Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment.
As shown in Figures 1 to 8, the multi-functional brushless lithium electric hammer drill of the Single button of the present embodiment, including the preceding machine being fixedly connected
Shell 1 and back cabinet 2, back cabinet 2 are spliced by left and right casing 21,22, and setting is solid inside front housing 1 and 2 junction of back cabinet
Reservation 3, is rotatablely connected parallel impact shaft assembly 4 and transmission shaft 5 between front housing 1 and fixing seat 3, impact shaft assembly 4 includes
Impacting shaft 42,42 rear end of impacting shaft are installed with cylinder 43, percussion hammer 44 are arranged in cylinder 43, is installed with inside 42 leading portion of impacting shaft of cooperation
It hammers column 45 into shape, brushless motor component 6 is fixed in back cabinet 2, the driving end of brushless motor component 6 passes through fixing seat 3 and transmission shaft 5 connects
It connects, spline 51 is fixed on transmission shaft 5, and be arranged the first, second clutch 52,53 with the cooperation clamping of spline 51 on transmission shaft 5,
First, second clutch 52,53 is separately connected driving gear 54 and Oscillating lever bearing 55, drives outside gear 54 and impact shaft assembly 4
The driven gear 41 of side connection engages connection, and the swing rod of Oscillating lever bearing 55 is connected by connecting pin and 43 rear end of cylinder pin, and first, the
Two clutches 52,53 are separately connected the first, second shift fork 56,57, and the convex of knob 7 is arranged between the first, second shift fork 56,57
Block, and knob 7 is rotatably coupled to 1 outside of front housing, the first, second shift fork 56,57 is all connected with reset far from 7 side of knob
Spring 58, the first, second shift fork 56,57 are through on shift fork guiding axis 59 fixed in front housing 1, and the first, second shift fork 56,
Two reset springs 58 of 57 connections are also set on shift fork guiding axis 59, and two 58 one end of reset spring are separately connected the
One, the second shift fork 56,57, the other end is fixedly connected with shift fork guiding axis 59, and back cabinet 2 is also connected with brushless motor controller 8
With electronic speed-regulating switch 9, brushless motor controller 8 connects lithium battery pack 81.
It is installed with guide pin 561 on first shift fork 56, the fixed tooth plate of fit engagement driven gear 41 is arranged on guide pin 561
562, and the buffer spring 563 for connecting fixed tooth plate 562 with the first shift fork 56 is also arranged on guide pin 561, pass through fixed tooth
The engageable driven gear 41 of plate 562 prevents the static friction band when carrying out single hammer operation, between transmission shaft 5 and driving gear 54
Dynamic driving gear 54 rotates, so that driven gear 41 be driven to rotate, plays locking function, when preventing from singly hammering into shape, cutter rotation.
It is located at knob 7 on the outside of front housing 1 and function Pointing sign board 71 is set, knob 7 is provided with lock-button 72, lock-button 72
Connection locking pressure spring 73, by 72 lockable knob 7 of lock-button, to lock hammer drill function.
The multi-functional brushless lithium electric hammer drill of the Single button of the present embodiment can connect cutter in use, passing through and impacting shaft assembly 4, when
When carrying out hammer drill operation, the rotation of knob 7 to centre, the first, second clutch 52,53 connects with the spline 51 of transmission shaft 5 at this time
It connects, at this time when transmission shaft 5 rotates, driving gear 54 and Oscillating lever bearing that the first, second clutch 52,53 can be driven to connect
55 rotations, driving gear 54 drive the driven gear 41 of engagement to rotate, impacting shaft 42 can be driven to rotate, and band cutter is bored
Operation, while the rotation of Oscillating lever bearing 55 can drive cylinder 43 to move forward and backward, and cooperate hammer by the percussion hammer 44 in cylinder 43
Column 45, hammers cutter, i.e. the operation of realization cutter hammer, i.e., carries out hammer drill operation simultaneously, when progress is single bores function, rotation
Button 7 is rotated to 53 direction of second clutch, and second clutch 53 can be driven to separate with spline 51, when transmission shaft 5 rotates at this time,
Oscillating lever bearing 55 does not rotate, and loses the operation of hammer, only retains the operation bored, and when singly hammer operation, knob 7 is to first clutch 52
Direction rotation, can drive first clutch 52 to separate with spline 51, when theoretically transmission shaft 5 rotates at this time, drive gear 54
It does not rotate, loses the operation of brill, only the operation of reservation hammer, since driving gear 54 and transmission shaft 5 have friction under actual conditions,
The rotation of transmission shaft 5 will drive driving gear 54 and rotate by a small margin, so that cutter still has to be turned by a small margin when causing single hammer operation
It is dynamic, in order to solve this problem, fixed tooth plate 562 is set on first clutch 52, knob 7 drives first clutch 52 mobile
While separation with spline 51, first clutch 52 drives fixed tooth plate 562 thereon to move, if the tooth of fixed tooth plate 562
Located on a straight line with the tooth socket of driven gear 41, then fixed tooth plate 562 is directly engaged with driven gear 41, passes through fixed tooth plate
562 position driven gear 41, can prevent impacting shaft 42 from rotating, if the tooth of the tooth of fixed tooth plate 562 and driven gear 41
Slot is out-of-line, and fixed tooth plate 562 is first against 41 side of driven gear, drives gear 54 and transmission shaft 5 to there is friction, passes
Moving axis 5 drives driving gear 54 to rotate, and driving gear 54 can drive driven gear 41 slightly to turn an angle, due to fixation
Buffer spring 563 is arranged in 562 side of tooth plate, when driven gear 41 turns to the tooth of tooth socket and fixed tooth plate 562 in a straight line
Position, fixed tooth plate 562 can be inserted into driven gear 41 under the action of buffer spring 563, can be fixed by buffer spring 563
Driven gear 41 is lived in position, can prevent impacting shaft 42 from rotating, and due to there is buffer spring 563 to play buffer function, prevents fixed tooth
Very stiff and demanding problem occurs for plate 562 and driven gear 41, prevents fixed tooth plate 562 and driven gear 41 from damaging.
Above description is explanation of the invention, is not intended to limit the invention, and limited range of the present invention is referring to right
It is required that the present invention can make any type of modification without prejudice to basic structure of the invention.
