Description
Technical field
The utility model relates to mechanized equipment technical field, specifically a kind of fixture for facilitating machine shaft to punch.
Background technique
With the innovation progress of technology, the model of motor is increasing in the market, at present when motor installs shaft, buying
The shaft of finished product motor does not meet requirement mostly, needs to change another shaft.But the gear of shaft and shaft end needs
It is connected by pin, it be in the shaft specific position drilling changed.Due to the difference in size, the fixture used that now drills is logical
With bench vice, it is not easy clamp and drilling effect is bad.
Meanwhile the pin being connect with shaft end gear for shaft is taper bolt, when assembly, need to throw stub end in axis into completely,
It need to be got from small head end when disassembly, consider that gear and motor body space length are narrow, it is to protrude into extrusion, phase with tweezers that operation is mostly
Between shaft rotate, therefore operate it is extremely inconvenient.
It is well known that motor is easily damaged device, exit that shank is inconvenient and tweezers have sharp one end with tweezers, it is easily right
Motor generates scratch, so that motor surface is generated impression using bench vice clamping, and shaft on motor arbitrarily bore by rotation
Hole is not easy, the shank of taking-up because it is small in size be easy to jump out and lose due to lose, cause damages.
Therefore, there is an urgent need to a kind of pair of motors effectively to clamp, be capable of fixing shaft is drilled, conveniently in narrow space
Shank is exited to the device of machine shaft.
Summary of the invention
In order to avoid with solve above-mentioned technical problem, the utility model proposes it is a kind of facilitate machine shaft punch folder
Tool.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of fixture for facilitating machine shaft to punch, the vee-block including holding motor body lower end, on the vee-block
It is connected with the pressing plate for pushing against motor body upper end, the head fixture block for holding machine shaft, the bottom of the vee-block is connected with pressure
Tight backing plate, be threaded on the compression backing plate it is horizontally disposed tighten screw, described tighten is connected with and head on screw
Fixture block cooperation can tighten briquetting for what gear compressed；It further include hand-held for installing and hitting the punching pin of shank.
Further, the part that the pressing plate is contacted with motor body is arc.
Further, the head fixture block is equipped with the V-shaped groove of support machine shaft.
Further, the bottom of the V-shaped groove is equipped with the cylindrical hole for collecting shank.
Further, the punching pin includes cylinder, is connected to formed punch tapered and elongated on cylinder.
Further, the pressing plate, head fixture block, compression backing plate are connected by screw on vee-block.
The beneficial effects of the utility model are:
The utility model have the advantages that structure is simple, easily fabricated, failure rate is low, it is safe and reliable, convenient for operation, make up
Existing deficiency of the operation without special fixture, the operation for facilitating machine shaft to drill, using tightening screw and tighten briquetting cooperation
Mode compress gear, avoid screw directly compress gear mesh strength of gear face generate impression possibility, avoid shaft from deforming,
The function of collecting shank is increased simultaneously, so that the utility model design more meets operational requirements.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure composition schematic diagram of the utility model；
Fig. 2 is the left view of the utility model；
Fig. 3 is the structural schematic diagram of punching pin in the utility model；
Fig. 4 is the structural schematic diagram one of head fixture block in the utility model；
Fig. 5 is the structural schematic diagram two of head fixture block in the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
It is further described in face of the utility model.
As shown in Figures 1 to 5, a kind of fixture for facilitating machine shaft to punch, the V-arrangement including holding motor body lower end
Block 1 is connected with the pressing plate 5 for pushing against motor body upper end, the head fixture block 2 for holding machine shaft, the V on the vee-block 1
The bottom of shape block 1, which is connected with, compresses backing plate 6, be threaded on the compression backing plate 6 it is horizontally disposed tighten screw 4, it is described
It tightens to be connected on screw 4 and can tighten briquetting 3 for what gear compressed with the cooperation of head fixture block 2；It further include hand-held for installing
With the punching pin 7 for hitting shank.
The part that the pressing plate 5 is contacted with motor body is arc.For convenience of operation, the design of fuselage briquetting 5 is not
Complete gland motor body.
The head fixture block 2 is equipped with the V-shaped groove 2a of support machine shaft.
The bottom of the V-shaped groove 2a is equipped with the cylindrical hole 2b for collecting shank.It is hit in use, cylindrical hole 2b solves shank
When collection problem.
The punching pin 7 includes cylinder 71, is connected to formed punch 72 tapered and elongated on cylinder 71.In use, installing, hitting
Punching pin 7 can be used in shank out, grows since formed punch 72 is thin, solve because pin hole diameter is small, the narrow space of fuselage and gear due to
Bring installation, disassembly problem.
The pressing plate 5, head fixture block 2, compression backing plate 6 are connected by screw on vee-block 1.Consider fuselage and gear
Narrow space, the collection of shank will facilitate, therefore the mating surface of each part has the requirement of roughness.
When the utility model is used, motor is clamped by vee-block 1 and briquetting 5, head fixture block 2 is inserted into motor gear and motor
Machine shaft is held between fuselage and by V-shaped groove 2a, while for convenience of operating, there is no complete glands for the design of fuselage briquetting 5
Motor body.
When shaft drills, screws and tighten screw 4, by tightening 3 clamping motor gear of briquetting, so that shaft rotation is limited,
Facilitate drilling；After drilling, by shank insertion drilling, shank is driven into drilling and realizes assembly by man-hour manually hand-held punching pin 7.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model also has
Various changes and modifications, these changes and improvements are both fallen in claimed invention.The requires of the utility model protection
Range is defined by the appending claims and its equivalent thereof.
