The specific embodiment
In the described embodiment of Fig. 1-8, Fig. 1-8 has schematically described an exemplary non-restrictive example of chuck system.Chuck system comprises tool chuck 50, and this chuck is assemblied in and is used for fixing annex (as drill bit) on the power drill/driver (as drilling machine).But can understand, tool chuck 50 also can suitably be assemblied in and be used for fixing multiple annex (except that drill bit) on the multiple power drill/driver (except that drilling machine).
A. structure
As shown in Figure 1, 2, but tool chuck 50 comprises chuck body 52, sleeve 60 and the claw (not shown) of support chuck driving shaft 55.Chuck driveshaft 55 rotations are installed on the chuck body 52.Chuck driveshaft 55 links together securely with the output shaft 30 of power drill/driver.Relative rotation between chuck driveshaft 55 and the chuck body 52 can actuation tool chuck 50 (promptly open and close claw).
For example, tool chuck 50 is equipped with " propeller " formula claw (not shown).Here, the front end of chuck driveshaft 55 is provided with radially to inner face screw thread 58.With the structural similarity described in ' 503 applications, radially interact to the screw thread of face radially outward of inner face screw thread 58 with chuck actuating screw (not shown), the chuck actuating screw can support claw.Interaction between the screw thread 58 of chuck driveshaft 55 and the screw thread of chuck actuating screw can make claw move forward and backward vertically with respect to chuck body 52.As can be seen, chuck actuating screw and chuck body 52 can lock together rotatably by claw.
Power drill/driver comprises casing 90.Casing 90 comprises main body 92 and the end cap 94 that is assembled together.In alternative embodiment, main body 92 and end cap 94 can be as a whole, i.e. integrative-structure.Casing 90 can support power shaft 10, output shaft 30 and hammer mechanism 70.
B. operation
The operation of tool chuck 50 is according to following factor and difference: the axial location of (1) rotation fixed ratchet wheel 74; (2) axial location of sleeve 60.Different operator schemes comprises (but being not limited to) boring/drive pattern, hammering pattern and fixing pattern.
Fig. 1,2 is depicted as the boring/drive pattern under the chuck system no-bias.As shown in the figure, rotation fixed ratchet wheel 74 is in axially backward position (and break away from rotation ratchet 72), so hammer mechanism 70 is in halted state.Simultaneously, sleeve 60 is positioned at axial forward facing position.In this case, the spline 56 (as shown in Figure 7) of chuck driveshaft 55 engages to spline 66 with the back of sleeve 60, and chuck body 52, chuck driveshaft 55 and sleeve 60 just can be in the same place by spin locking like this, and rotate together as a unit.Because chuck body 52 is in the same place with chuck driveshaft 55 spin lockings, tool chuck 50 just can not become flexible in operation.
The user starts driver with rotation driving power shaft 10 then, makes it with respect to 74 rotations of rotation fixed ratchet wheel.Power shaft 10 rotates driving output shaft 30 by the joint that drives between lug 16 and the driven lug 26.Under the effect of spring 6, the inclined-plane that is tapered of driving lug 16 surpasses being tapered the inclined-plane of driven lug 26 and is inserted in the connecting portion 20.Under this state, will provide torque to connect, in this torque connect, all torque transfer of power shaft 10 were to output shaft 30.Output shaft 30 rotary drive tool chucks 50.
To similar shown in Fig. 1,2, be boring/drive pattern shown in Fig. 3,4, different is that chuck system is in bias state.Such as, when the user was pressed against annex (as drill bit) on the workpiece, bias voltage (perhaps external force) had just taken place.As shown in the figure, bias voltage can overcome the flange 34 of output shaft 30 and the influence of the spring (not shown) between the bearing 4, Move tool chuck 50 on respect to axially backward the direction of casing 90 (and therefore mobile output shaft 30 and power shaft 10).
Therefore output shaft 30 (and tool chuck 50) axially backward motion be subjected to pressing the restriction of the flange 34 of bearing 4.Like this, because axially moving backward of the assembly due to the bias voltage just is restricted, therefore rotate ratchet 72 and be kept away from rotation fixed ratchet wheel 74 (just hammer mechanism 70 keeps stopping), and sleeve 60 is kept away from end cap 94.After bias voltage was removed, assembly will be got back to the state shown in Fig. 1,2.
Fig. 5,6 is depicted as the hammering pattern of chuck system bias voltage.The user rotation fixed ratchet wheel 74 is moved on axial forward direction and the influence that overcomes spring 6 to realize the hammering pattern.Because chuck system is biased, output shaft 30 (relying on connecting portion 20), mobile power shaft 10 (and therefore moving rotation ratchet 72) and overcome the influence of spring 6 on axial backward direction.In this state, rotation fixed ratchet wheel 74 engages with rotation ratchet 72.Be appreciated that after removing bias voltage from chuck system spring 6 can make rotation ratchet 72 (and power shaft 10 and output shaft 30) move to axial position forward, this can make ratchet 72,74 break away from.
The user starts driver then, drive power shaft 10 (with rotating ratchet 72 together) with rotation, and power shaft 10 will be with respect to 74 rotation of spinning roller fixed ratchet wheel.If chuck system keeps bias voltage, the relative rotation between the ratchet 72,74 just causes power shaft 10, output shaft 30 and tool chuck 50 with respect to casing 90 relative displacement to take place so, thereby produces reciprocal axially-movable.For example, as shown in the figure, rotation ratchet 72 chord commentaries on classics fixed ratchet wheel 74 all has tooth separately.When the tooth of rotation ratchet 72 rode on the tooth that rotates fixed ratchet wheel 74, rotation ratchet 72 was vertically away from rotation fixed ratchet wheel 74.When tooth each other through out-of-date, be applied to bias voltage on the chuck system and make rotation ratchet 72 get back to axial location shown in Fig. 5,6.Like this, after driver starts, tool chuck 50 will rotate and be axially reciprocal.
Fig. 7,8 is depicted as the fixing pattern.As just example, power drill/driver can be when the non-bias voltage of chuck system (as shown in the figure) be under the fixing pattern and operate.Rotation fixed ratchet wheel 74 is in axially position (and breaking away from rotation ratchet 72) backward, so that hammer mechanism 70 stops.Simultaneously, the user can move to axially position backward with sleeve 60.In this axially-movable process, the back spline 56 to spline 66 and chuck driveshaft 55 of sleeve 60 breaks away from (thereby chuck driveshaft 55 is with respect to chuck body 52 rotations), and sleeve lug 68 can enter in the depression 98 of end cap 94 (thereby sleeve 60 and chuck body 52 can rotate on the casing 90 that is installed in power drill/driver).
When sleeve lug 68 enters depression 98, therefore sleeve lug 68 is backward directions drive pin 8 (and drive power shaft 10) and overcome the influence of spring 6 vertically.Output shaft 30 (and so connecting portion 20) under the effect of the spring (not shown) between flange 34 and the bearing 4, remains on axial forward facing position.Thus, axially moving backward of power shaft 10 will cause driving the driven lug 26 that lug 16 partly leaves connecting portion 20, can be on the be tapered inclined-plane (as shown in Figure 8) of circumferencial direction in the face of driven lug 26 so that drive the inclined-plane that is tapered of lug 16.
The user can start driver and rotate driving power shaft 10.Power shaft 10 rotates by the joint that drives lug 16 and driven lug 26 and drives output shaft 30.Output shaft 30 is with respect to chuck body 52 (being installed on the casing 90 by sleeve 60 rotations) rotation drive chuck driving shaft 55.As described in ' 503 applications, the relative rotation of (and so chuck actuating screw and claw) is with actuation tool chuck 50 (just opening and/or close claw according to the direction of operating of power drill/driver) between chuck driveshaft 55 and the chuck body 52.In addition, during chuck actuating, chuck body and claw do not rotate.Because the user is not easy to be subjected to the influence of (or observing) any rotary part, this just is called what is called " dead axle " feature.
In the chuck actuating process, when tool chuck 50 does not does not open or close (for example when claw is is still opening or closing) fully, power shaft 10 can drive output shaft 30 rotatably by the interaction that drives between lug 16 and the driven lug 26.When tool chuck 50 is closed (annex that is with or without insertion) fully or opened fully, the revolving force that driving lug 16 affacts on the driven lug 26 will strengthen.This revolving force is increased to a threshold value, matches on the inclined-plane that is tapered of this lug 16,26 to drive power shaft 10 and overcome the influence of spring 6 on axial backward directions, therefore drives the end that lug 16 slips over driven lug 26.In this case, drive lug 16 and driven lug 26 a clutch feature can be provided, be used for limiting the torque that is applied in the chuck actuating process.
Be appreciated that the value that drives the required revolving force of power shaft 10 on axial backward direction is subjected to the influence as the spring constant of the angle of inclination on the inclined-plane that is tapered of lug 16,26 and/or spring 6.In addition, by the be tapered profile on inclined-plane of suitable design, can make the torque threshold of the torque threshold of fastened tools chuck 50 less than back off tool chuck 50, vice versa.
In the described embodiment of Fig. 9-14, Fig. 9-14 has schematically described an exemplary and nonrestrictive tool chuck 150.This tool chuck can be applicable to in the described chuck system in top.Shown in Fig. 9-14, tool chuck 150 receives the handle of annex 105 movably.
A. structure
Shown in Fig. 9-11, tool chuck 150 comprises chuck body 152.Chuck body 152 rotation support chuck driving shafts 155.In this exemplary and nonrestrictive embodiment, chuck driveshaft 155 has two assemblies that comprise lining 110 and drive sleeve 120.Lining 110 is connected on the output shaft 130 of power drill/driver securely.Lining 110 comprises spline 116 (as shown in figure 10), and spline 116 selectively cooperates to spline 166 (as shown in figure 11) with the back of sleeve 160.Lining 110 also comprises forward direction clutch surfaces 112 (as shown in figure 10), and forward direction clutch surfaces 112 cooperates to clutch surfaces 122 (as shown in figure 11) with the back of drive sleeve 120.
Chuck actuating screw 180 comprises radial passage 186, and claw 101 can slide via these passages respectively.Radial passage 186 is rotatably fixed to chuck actuating screw 180 on the claw 101.Interaction between the screw thread 128 and 188 causes that chuck actuating screw 180 advances in the axial direction with respect to chuck body 152 or retreats.
The front end of chuck body 152 supports noses 140 and pawl fixator 145 securely.Noses 140 are taper, and around pawl fixator 145.Pawl fixator 145 has tipper 147 (as shown in figure 10), and claw 101 can slide through these grooves respectively.Claw 101 has the tab 103 that can slide along the outline that is tapered of pawl fixator 145.The radially inner surface pressure of noses 140 is removed from the groove 147 of pawl fixator 145 to prevent claw 101 by the surface radially outward of tab 103.Be appreciated that chuck actuating screw 180, noses 140 and pawl fixator 145 can be in the same place by claw 101 spin lockings.
The axial location of sleeve 160 (with respect to chuck body 152) is subjected to the influence of lock pin 157.In the embodiment that changes, be provided with a plurality of lock pins 157.Lock pin 157 is by the radially outside bias voltage of spring 159.Lock pin 157 and spring 159 are contained in the depression of chuck body 152.The interaction of the groove 167 of lock pin 157 and sleeve 160 so that influence the axial location of sleeve 160, will be described in detail below.
B. operation
Figure 12 shows that boring/drive pattern.As shown in the figure, sleeve 160 is positioned at the axial centre position with respect to chuck body 152.In this state, between two inclined-planes 161,162 that lock pin 157 sets in groove 167.The axial location of sleeve 160 in use can be offset.During this skew, inclined-plane 161,162 and spring-loaded lock pin 157 interacts, to influence the axial centre position of sleeve 160 shown in getting back to.
In addition, the spline 116 of lining 110 engages to spline 166 with the back of sleeve 160, causes chuck body 152, chuck driveshaft 155 (comprising lining 110 and drive sleeve 120) and sleeve 160 to lock together rotatably, and as a unit rotation.Like this, tool chuck 150 can not become flexible at work.
The user starts driver, and rotation drives output shaft 130, drives output shaft 130 rotary drive tool chuck 150 and annex 105 again successively.
Figure 13 shows that assembly mode.User's moving sleeve 160 is to axial forward location, to realize assembly mode.In this axially-movable, the inclined-plane 161 of groove 167 is radially driving lock pin 157 on the inward direction, and overcomes the influence of spring 159.Sleeve 160 remains on axial forward location versatilely, causes the part of lining 110 to come out.
The expose portion of lining 110 can be grasped by instrument, with permission tool chuck 150 is assembled on the output shaft 130 of power drill/driver, perhaps it is unloaded from output shaft 130.In case when releasing activity kept, inclined-plane 161 and spring-loaded lock pin 157 just can interact, so that sleeve 160 is got back to axial centre position as shown in figure 12.
Figure 14 shows that the fixing pattern.At this, the user can move on to sleeve 160 axial back to the position.When this initially moved axially, the inclined-plane 162 of groove 167 was radially driving lock pin 157 on the inward direction, and overcomes the influence of spring 159.In further moving axially, lock pin 157 (under the effect of spring 159) radially outward direction moves, and strides across inclined-plane 164.
In addition, the back spline 116 to spline 166 disengaging linings 110 of sleeve 160 is so that chuck driveshaft 155 (comprising lining 110 and drive sleeve 120) can relative chuck body 152 rotations.The lug 198 of end cap 194 enters into the depression 168 of sleeve 160.In this state, sleeve 160, chuck body 152, noses 140, pawl retainer 145 and claw 101 are installed on the casing 190 of power drill/driver revolvably.
The user starts driver with rotation driving output shaft 130 then.Output shaft 130 rotatable driving linings 110.Lining 110 rotates by the joint between interface 112 and 122 and drives drive sleeve 120.Drive sleeve 120 is with respect to 180 rotations of chuck actuating screw, and its (by claw 101, noses 140, pawl retainer 145, chuck body 152 and sleeve 160) remains on the casing 190.This relative rotation causes chuck actuating screw 180 by radially to inner face screw thread 128 and the interaction between the face screw thread 188 radially outward, advances in axial direction or retreats (according to the direction of rotation of drive sleeve 120).This moving of chuck actuating screw 180 can push away or draw claw 101 (by 147 guidings of the tipper on the pawl retainer 145), so that it opens or be closed.
During chuck actuating, sleeve 160, chuck body 152, noses 140, pawl retainer 145, claw 101 and chuck actuating screw 180 keep being installed in rotatably on the casing 190, chuck actuating screw 180 can move (by rotatablely moving of drive sleeve 120) in the axial direction relative to chuck body 152 simultaneously, to open or closed claw 101.Because the user is not easy to be subjected to the influence of (or observing) any rotary part, this just is called as what is called " dead axle " feature.
In the chuck actuating process, when tool chuck 150 does not does not open or close fully (when still opening or closing such as claw 101), lining 110 drives drive sleeve 120 by the rotation of the interaction between the interface 112 and 122.When tool chuck 150 was closed (annex 105 that is with or without insertion) fully or opened fully, the revolving force that lining 110 is applied on the drive sleeve 120 can strengthen.This revolving force is increased to a threshold value, and interface 112 and 122 will get out of the way (or slip) under this threshold values, with the torque that applies in the restriction chuck actuating process.When interface 112 and 122 slided, drive sleeve 120 (with chuck body 152 and sleeve 160) will be vertically forwards to the influence that is driven and overcomes spring 106.Yet, should be appreciated that this (when the occurring in the clutch slip) deficiency that axially travels forward is so that the lug 198 of end cap 194 breaks away from the depression of sleeves 160.
It will be appreciated that the value axially forwards upwards driving drive sleeve 120 required revolving forces is subjected to the influence as the spring constant of interface 112 and 122 geometrical constructions and/or spring 106.In addition, by the geometrical construction of suitable design interface 112 and 122, make the torque threshold of the torque threshold of fastened tools chuck 150 less than back off tool chuck 150, vice versa.
