Description
Technical field
The present invention relates to grinding device technical fields, more particularly to a kind of polishing device for hollow shaft center hole of motor train unit.
Background technology
When the centre bore to axle of motor train unit is machined out, since centre bore is overproof, surface is jagged or speckles with iron
It considers to be worth doing and generates bounce, reduce mach precision and easy to produce waste product.Therefore, it before machining, needs to beat centre bore
Mill is repaired, and the requirement of process for machining is reached.Currently, to the method that the polishing of centre bore is repaired, it is usually logical with sand paper
Artificial manual grinding is crossed to complete.This polishing process there are working efficiencies low, the big disadvantage of labor intensity.
Invention content
The technical problem to be solved by the present invention is to low to the polishing working efficiency of centre bore at present, labor intensity is big.
In order to solve the above technical problems, the present invention provides a kind of polishing device for hollow shaft center hole of motor train unit, including beat
Grinding machine main body, the grinding head being connect with sander main body offer sand paper folder hole on the grinding head；
One end of sander main body towards the grinding head offers sliding slot, and sliding connection in the sliding slot, there are two limits
Block offers threaded hole on two limited blocks, and the hand of spiral of the threaded hole on two limited blocks is opposite；
Two threaded hole internal threads are connected with screw rod, and the screw rod is connect with sander body rotation.
Technique effect：The sander main body that the present invention is arranged can drive grinding head to work, and sand paper folder hole is used to place sand paper,
Start sander body of work, grinding head rotation can utilize the sand paper of rotation to the hole of centre bore to drive sand paper to rotate
Wall is polished, and to substitute manual polishing, grinding efficiency is high, labor intensity is also low, and makes polishing effect good；In addition, by
During the work time in sander main body, vibration is will produce, and can be shaken when operating personnel's hand-held grinder main body, so as to
Lead to grinding head centre of percussion hole hole wall, the hole wall of centre bore is damaged, two limited blocks and screw rod that the present invention is arranged
It is threadedly coupled, and the hand of spiral of the threaded hole on two limited blocks can make two limited blocks same on the contrary, when then rotating screw rod
When it is close to each other or be located remotely from each other simultaneously, when needing to centre hole polishing, rotate screw rod first, keep two limited blocks mutual
It is close, by limited block deeply into the inlet in hole, screw rod is then rotated, two limited blocks is made to be located remotely from each other, finally and center
The hole wall of hole inlet contradicts, and realizes the limit to sander main body, sander main body is made not shaken in work process
It is dynamic, and grinding head is in stable state, will not center of impact hole hole wall, in addition, the gravity of sander main body and grinding head is not
Operating personnel can be fully fallen on hand, operating process is lighter.
The technical solution that the present invention further limits is：
Further, the limited block is arc-shaped, and the inside of limited block described in two arcs is close to each other.
The preceding polishing device for hollow shaft center hole of motor train unit, the one end of the limited block far from sander main body are mutual
Close, the angle between the limited block and sander main body is 55-65 °.
The preceding polishing device for hollow shaft center hole of motor train unit, the distance between two limited blocks and grinding head phase
Deng.
The preceding polishing device for hollow shaft center hole of motor train unit, the grinding head are taper grinding head.
The preceding polishing device for hollow shaft center hole of motor train unit, the side that the limited block is located remotely from each other are equipped with rubber
It pads, non-slip texture is offered on the rubber pad.
The beneficial effects of the invention are as follows：
（1）Camber is arranged in limited block in the present invention, it can be made preferably to be bonded with the hole wall of centre bore, to make
Limited block is more stable, and then sander main body is made more to stablize, in addition, the present invention is by one of limited block far from sander main body
Hold close to each other, and the angle between limited block and sander main body is 55-65 °, can be further by limited block and center
The hole wall in hole stablizes fitting.
（2）By the equal of the distance between two limited blocks and grinding head setting in the present invention, grinding head can be made to be in
The center of centre bore, and then the contact that the emery cloth of grinding head both sides can be made to stablize with the hole wall of centre bore, so as to
There is preferable polishing effect to the hole wall of centre bore；
（3）On the one hand the rubber pad being arranged in the present invention can improve the frictional force between limited block and centre bore hole wall,
So that limited block is tended towards stability, on the other hand can slow down destruction of the limited block to centre bore hole wall.

Specific implementation mode
A kind of polishing device for hollow shaft center hole of motor train unit provided in this embodiment, structure are as shown in Figs. 1-3.
The polishing device for hollow shaft center hole of motor train unit, including sander main body 1, the polishing that is connect with sander main body 1
First 2, grinding head 2 is taper grinding head, and sand paper folder hole 21 is offered on grinding head 2, and sander main body 1 drives.
One end of sander main body 1 towards grinding head 2 offers sliding slot 3, and sliding connection in sliding slot 3, there are two limited blocks
31, offer threaded hole 311 on two limited blocks 31, and the threaded hole 311 on two limited blocks 31 hand of spiral on the contrary,
Two 311 internal threads of threaded hole are connected with screw rod 312, and screw rod 312 is rotatablely connected with sander main body 1, then rotates screw rod 312
When, two limited blocks 31 can be made close to each other simultaneously or be located remotely from each other simultaneously.
Limited block 31 is arc-shaped, and the inside of two arc-shaped limit blocks 31 is close to each other, and limited block 31 is far from polishing owner
One end of body 1 is close to each other, and the angle between limited block 31 and sander main body 1 is 55-65 °, and limited block 31 can be made more preferable
Be bonded with the hole wall of centre bore, to keep limited block 31 more stable, so make sander main body 1 more stablize.
Two limited blocks 31 are equal with the distance between grinding head 2, and the side that limited block 31 is located remotely from each other is equipped with rubber pad
