The utility model discloses in the course of working, the extension is generated heat by the processing part, and the part after the extension passes through thimble, dog and will exert power on the spring, and the spring pressurized is out of shape, and automatic compensation has been avoided by the extension of processing part by the pressure between the centre bore of processing part and the thimble too big, and the centre bore precision decline problem of the processing part that causes.

Description

Internal and external groove grinding machine tailstock

Technical Field

The utility model relates to the technical field of machining, specifically be an interior outer ditch grinding machine tailstock.

Background

A grinding machine is a machine tool that grinds the surface of a workpiece using a grinding tool. Most grinding machines use a grinding wheel rotating at a high speed for grinding, and a few grinding machines use other grinding tools such as oilstone and abrasive belt and free abrasive materials for processing, such as honing machines, superfinishing machines, abrasive belt grinding machines, polishing machines and the like.

At present, in a machining process, a part extends due to heating, so that the pressure of a central hole of the machined part on a tailstock ejector pin is increased sharply, the friction force between the central hole of the machined part and a tailstock center is too large, the precision of the central hole of the machined part is reduced, the machining precision of the machined part is reduced finally, a large amount of scraps are generated when a grinding machine is used for grinding the part, and the tailstock and a rail are seriously worn if the scraps are not treated in time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an interior outer ditch grinding machine tailstock to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an interior ditch grinding machine tailstock of outer, includes tailstock body and box, the tailstock body is provided with the spout, the tailstock body is provided with the cavity, cavity fixedly connected with fan, cavity fixedly connected with filter screen groove, swing joint has the filter screen in the filter screen groove, cavity hinged joint has the cabinet door, tailstock body fixedly connected with box, box top swing joint has the connecting rod, connecting rod upper end fixedly connected with hand wheel, the box is provided with the circular recess, be provided with the spring in the circular recess, spring left end and box fixed connection, spring right-hand member fixedly connected with dog, dog fixedly connected with preloading device, swing joint has the thimble in the preloading device.

Preferably, the cabinet door is provided with a handle.

Preferably, the filter screen is made of soft plastic materials.

Preferably, a controller is arranged on the tailstock body.

Preferably, the surface of the hand wheel is provided with a soft leather sleeve.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses in the course of working, the part that is processed generates heat and extends, and the part after the extension exerts power on the spring through thimble, dog, and the spring is compressed and is out of shape, has compensated the elongation of part that is processed automatically, has avoided the too big pressure between centre bore and the thimble of part that is processed, and the centre bore precision of part that causes descends the problem to be processed to improved the machining precision of part that is processed;

2. the utility model discloses can produce various sweeps in the course of working, open the switch of fan this moment, the fan is bloied to the orbit of tailstock body and is handled, blows away the sweeps on the track, avoids impurity to cause serious wearing and tearing to tailstock main part and inside and outside ditch grinding machine track, has improved the life of tailstock main part greatly.
