Description

The electronic poll pick of spring
Technical field
The present invention relates to power tools technology field, more particularly, to a kind of electronic poll pick of spring.
Background technology
Electronic poll pick is one kind of electric drill, is mainly used to drill on concrete, floor, brick wall and stone material.Common electricity Dynamic poll pick is on the basis of electric drill, increases a piston for having crankshaft-link rod by motor driven, reciprocal in a cylinder Compressed air, it is in mechanical periodicity to make cylinder inner air pressure, and the air pressure of change drives the hammer in cylinder back and forth to hit brill The top of head, similar to hammer percussive drill bit.Because the drill bit of electronic poll pick is also created along electric drill while rotating The faster reciprocal motion (frequent impact) in the direction of bar, so it can be on the material such as the big cement concrete of fragility and stone material Quick punching.High-grade electronic poll pick can utilize change-over switch, the drill bit of electronic poll pick is in different working conditions, i.e., only Rotation is not impacted, or only impacts and do not rotate, or has not only impacted but also rotated.
The present invention is the improvement to the electronic poll pick of tradition.
The content of the invention
For above-mentioned the shortcomings of the prior art, it is an object of the invention to provide a kind of electronic poll pick of spring, and it has There is the characteristics of simple in construction, operating efficiency is higher.
To achieve these goals, the technical solution adopted in the present invention is:The electronic poll pick of spring, including casing, should Motor is provided with casing, and the upside left part of the casing is provided with block stamp, the left part of the block stamp is provided with extends to the casing to the left Outside tool heads, it is additionally provided with the casing:
Locating snap ring, the locating snap ring remain static relative to the casing, and the locating snap ring has the penetrating cooperation in left and right Hole, the side wall of the mating holes are provided with inwardly projecting stop protrusion;
Sprocket wheel, the sprocket wheel is rotatable relative to the casing but can not move left and right, and the sprocket wheel has left and right penetrating Perforate, ball is embedded with the side wall of the perforation;
Screw mandrel, the screw mandrel can horizontally slip, meanwhile, the left end of the screw mandrel is through in the mating holes and the perforation, and the silk The left part surface of bar is provided with and the stop ear of stop protrusion matching, the helicla flute that right part surface is provided with and ball matches;
Spring, the left end of the spring withstands on the right part of the leading screw, right-hand member is withstood on the casing;And
The left end of the screw mandrel and the block stamp match;
The sprocket wheel power connector is to the motor.
The sprocket wheel is coaxially fixed with a driven gear by belt power connector a to driving pulley, the driving pulley, The driven gear is engaged with a driving gear, and the driving gear is fixed on the power output shaft of the motor.
After said structure, the invention has the advantages that compared with the prior art,:It is simple in construction, operating efficiency compared with It is high.The electronic poll pick of spring of the present invention drives screw mandrel to move right by the rotation of clasp, after being moved to a certain degree, screw mandrel Departing from the limitation of locating snap ring can be rotated, i.e., can under the action of the spring, and drive screw is impacted forward, tool heads is had impact Ability.Because the part that the electronic poll pick of the spring uses is less, structure is relatively simple, and the potential energy of spring directly acts on silk On bar, operating efficiency has been significantly greatly increased.

Embodiment
Embodiment, as shown in Fig. 1 to Fig. 6:The electronic poll pick of spring, including casing 10.Certainly, the casing 10 has hand The structures such as handle, skull.Is provided with motor 20 in the casing 10, the motor 20 is necessarily connected to power supply by switching, and the switch can be with It is arranged on the positions such as the handle of the casing 10.The upside left part of the casing 10 is provided with block stamp 30, and the left part of the block stamp 30 is provided with The tool heads 40 of the outside of the casing 10 are extended to the left.The tool heads 40 can be the pick that right part is plugged on the block stamp 30 Head or drill bit etc..
It is additionally provided with the casing 10:The parts such as locating snap ring 50, sprocket wheel 60, screw mandrel 70, spring 80.
Wherein:
The locating snap ring 50 remains static relative to the casing 10.For example the locating snap ring 50 is fixed in the casing 10. The locating snap ring 50 has the penetrating mating holes 51 in left and right, and the side wall of the mating holes 51 is provided with inwardly projecting stop protrusion 52. So-called protrude inwardly from refers to that bearing of trend points to the center of the locating snap ring 50.
The sprocket wheel 60 is rotatable relative to the casing 10 but can not move left and right.Such as the two end portions of the sprocket wheel 60 It is not fixed in the inner ring of two bearings, and the outer ring of bearing is fixed on inside the casing 10.The sprocket wheel 60 has left and right penetrating Perforation 61, be embedded with ball 62 in the side wall of the perforation 61.Ball 62 also can be the cylinder with spherical head.
The screw mandrel 70 can horizontally slip.Meanwhile the left end of the screw mandrel 70 is through in the mating holes 51 and the perforation 61.The silk The left part surface of bar 70 is provided with and the stop ear 71 of the matching of stop protrusion 52, the spiral that right part surface is provided with and ball 62 matches Groove 72.That is, when the left part of the screw mandrel 70 is located in the locating snap ring 50, stop protrusion 52 and stop ear 71 can form phase Mutually stop, the screw mandrel 70 is not rotated;Ball 62 is stuck in helicla flute 72, after ball 62 rotates with the sprocket wheel 60, once The screw mandrel 70 can not rotate, then necessarily drive the screw mandrel 70 to move right.
The left end of the spring 80 withstands on the right part of the leading screw 70, right-hand member is withstood on the casing 10.That is, the spring 80 makes this Screw mandrel 70 has the trend being moved to the left.
More specifically:
The left end of the screw mandrel 70 and the block stamp 30 match.That is, the screw mandrel 70 can be formed after being moved to the left to the block stamp 30 Impact.
The power connector of sprocket wheel 60 is to the motor 20.That is, the motor 20 can drive the sprocket wheel 60 to rotate.
In the present embodiment, the power connector of sprocket wheel 60 to the mode of the motor 20 is:The sprocket wheel 60 passes through the power of belt 91 A driving pulley 921 is connected to, the driving pulley 921 is coaxially fixed with a driven gear 922, and the driven gear 922 is engaged with One driving gear 93, the driving gear 93 are fixed on the power output shaft of the motor 20.That is, after the motor 20 work, the master Moving gear 93 rotates, and drives the driven gear 922 to rotate, the synchronous rotary of driving pulley 921, drives this to buckle by the belt 91 The rotation of wheel 60.
The operation principle of the present invention:In an initial condition, the left part of the screw mandrel 70 can not by the constraint of the locating snap ring 50 Rotation.After the sprocket wheel 60 rotation, ball 62 drives the screw mandrel 70 that can not be rotated to move right, and the spring 80 compression has enough bullets Property potential energy.In impact conditions, with moving right for the screw mandrel 70, the screw mandrel 70 departs from the constraint of the locating snap ring 50, the silk Bar 70 can be rotated, and in the presence of the spring 80, the screw mandrel 70 is moved to the left rapidly, and the screw mandrel 70 impacts the block stamp 30, should Tool heads 40 obtain one-shot.After the completion of impact, the left part of the screw mandrel 70 is again by the constraint of the locating snap ring 50.Walk above Suddenly, circulation is carried out.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, every utilization The equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations Technical field, be included within the scope of the present invention.
