Abstract
The utility model discloses a polishing device for the hollow shaft center hole of a motor train unit, and solves the problems of low accuracy of center hole polishing and repairing and high probability of new exceed difference in the prior art. The polishing device comprises a polisher main body (1), and a tapered polishing head (5) made of nylon, wherein the tapered tail part connecting handle (2) of the tapered polishing head (5) is connected together with the polisher main body (1) through a locking device (3), a cross-shaped abrasive paper fixing groove (6) is formed at the head of the tapered polishing head (5), and in the cross-shaped abrasive paper fixing groove (6), the horizontal groove is wider than the vertical groove, so as to be suitable for abrasive papers with different thicknesses to be inserted. The polishing device for the hollow shaft center hole of the motor train unit achieves quick and accurate polishing to the hollow shaft center hole of the motor train unit.
Description
Technical field
The present invention relates to a kind of EMUs hollow shaft centre bore sanding apparatus, particularly a kind of device of being polished fast in the centre bore surface of EMUs axletree of being used for.
Background technology
When the centre bore to the EMUs axletree carries out machined, overproof owing to centre bore, the surface is jagged or speckle with iron filings produces and beat, reduce mach precision and be easy to generate waste product.Therefore, before machined, need repair, make it reach the requirement of process for machining the centre bore polishing.At present, to the method that the polishing of centre bore is repaired, generally be to accomplish through artificial manual grinding with sand paper.This polishing process be difficult to guarantee that polishing repairs precision, and can cause new overproof.In addition, also there is inefficiency in manual grinding, and labour intensity is big, the vulnerable shortcoming of operating personnel.
Summary of the invention
The invention provides a kind of EMUs hollow shaft centre bore sanding apparatus, it is not high to the polishing reparation precision of centre bore to have solved prior art, is easy to generate new overproof problem.
The present invention overcomes the above problems through following scheme:
A kind of EMUs hollow shaft centre bore sanding apparatus; Comprise the polishing machine main body; The taper rubbing head of nylon material, the tapered tail of taper rubbing head connect handle and link together through locking device and polishing machine main body, are provided with criss-cross sand paper holddown groove at the head of described taper rubbing head; And the translot of criss-cross sand paper holddown groove is wider than vertical slot, to be applicable to the sand paper that embeds different-thickness.
The tapering α of the head of described taper rubbing head is 60 degree or 90 degree.
Be movably set with the sand paper that two back-to-back sand stick together towards the other places in translot in described criss-cross sand paper holddown groove or the vertical slot, these two the back-to-back sand paper edge directions opposite with the rubbing head direction of rotation that stick together the head both sides that reach the taper rubbing head fold.
The present invention has realized the precisely polishing fast of EMUs hollow shaft centre bore, has reduced polishing and has repaired labour intensity, has improved operating efficiency.

Specific embodiment
A kind of EMUs hollow shaft centre bore sanding apparatus comprises polishing machine main body 1, the taper rubbing head 5 of nylon material; The tapered tail of taper rubbing head 5 connects handle 2 and links together through locking device 3 and polishing machine main body 1; Head at described taper rubbing head 5 is provided with criss-cross sand paper holddown groove 6, and the translot of criss-cross sand paper holddown groove 6 is wider than vertical slot, to be applicable to the sand paper that embeds different-thickness; When the thickness of sand paper is thicker; The sand paper activity is inserted in the translot of broad, when sand paper volume thinner thickness, the sand paper activity is inserted in the narrower vertical slot.
The tapering α of the head of described taper rubbing head 5 is 60 degree or 90 degree.
Be movably set with the sand paper that two back-to-back sand stick together towards the other places in translot in described criss-cross sand paper holddown groove 6 or the vertical slot; These two the back-to-back sand paper edge directions opposite with the rubbing head direction of rotation that stick together the head both sides that reach taper rubbing head 5 fold, and sand paper is polished as windmill is even.
Claims (3)
