Abstract
The utility model discloses a workpiece shaft for an inner groove grinder for a bearing ring. The workpiece shaft for the inner groove grinder for the bearing ring comprises a shaft sleeve, a workpiece shaft support is arranged in the shaft sleeve, the workpiece shaft penetrates through and is connected with the workpiece shaft support, and a magnetic coil, a water baffle plate and a workpiece backer are arranged at the front end of the workpiece shaft in sequence, wherein a workpiece shaft end cover is fixedly arranged between the shaft sleeve and the magnetic coil in sealed mode, at least one compressed air pipe is arranged in the workpiece shaft end cover, and an air outlet of the compressed air pipe is located at the position of a clearance between the magnetic coil and the workpiece shaft. Due to the fact that the compressed air pipe is arranged in the workpiece shaft end cover, and the air outlet of the compressed air pipe is located at the position of the clearance between the magnetic coil and the workpiece shaft, in the working process, through motive power of compressed air, grinding liquid in the clearance between the magnetic coil and the workpiece shaft can be blown out, and therefore the magnetic coil is protected.
Description
Technical field
The utility model relates to a kind of workpiece spindle, especially a kind of workpiece spindle for groove grinder in the bearing ring.
Background technology
Workpiece is in process, and because the grinding meeting produces a large amount of heats, will use the grinding fluid shower nozzle this moment, and grinding fluid is sprayed on the position that workpiece contacts with emery wheel, cools off workpiece with this between emery wheel and the workpiece.In this process, have the gap that the part grinding fluid enters into grinding machine and magnetic coil, and in the grinding fluid with materials such as iron filings, can affect magnetic coil and the problems such as wearing and tearing, corrosion occur.
In order to solve problem last time; current technical scheme is to add a water fender in the front of magnetic coil; stop grinding fluid to enter magnetic coil with this; although this method can stop most grinding fluid; but still have partially liq under the workpiece and emery wheel drive of High Rotation Speed; enter in the magnetic coil, so this magnetic coil is frequent or the problems such as wearing and tearing, corrosion can occur, needs needed for repair and replacement.
The utility model content
The utility model is for the problems referred to above, enter the problem of magnetic coil in order to solve grinding fluid, purpose is to provide a kind of workpiece spindle for groove grinder in the bearing ring, this workpiece spindle is with a compressed air line, the grinding fluid that enters magnetic coil can be blown out, thereby guarantee that magnetic coil does not go wrong.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of workpiece spindle for groove grinder in the bearing ring, comprise axle sleeve, being provided with workpiece spindle in the axle sleeve the inside supports, workpiece spindle passes the workpiece spindle support and is attached thereto, the front end of workpiece spindle is disposed with magnetic coil, water fender, workpiece backer, between axle sleeve and magnetic coil, fix and seal and be provided with the workpiece spindle end cap, be provided with at least one compressed air hose in the workpiece spindle end cap, the gas outlet of described compressed air hose is positioned at the gap of magnetic coil and workpiece spindle.
The beneficial effects of the utility model are: because the utility model is provided with compressed air hose in the workpiece spindle end cap; the gas outlet of this compressed air hose is positioned at the gap of magnetic coil and workpiece spindle; when therefore working; by compressed-air actuated power; the grinding fluid that enters the gap of magnetic coil and workpiece spindle can be blown out, thereby play the effect of protecting magnetic coil.
Description of drawings
Fig. 1 is structure chart of the present utility model;
Fig. 2 is A-A cutaway view of the present utility model.
Among the figure: axle sleeve 1, workpiece spindle support 2, workpiece spindle 3, workpiece spindle end cap 4, magnetic coil 5, compressed air hose 6, water fender 7, workpiece backer 8.
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
As shown in the figure, the a place is the gap of the utility model magnetic coil 5 and workpiece spindle 3, a kind of workpiece spindle for groove grinder in the bearing ring of the utility model, comprise axle sleeve 1, be provided with workpiece spindle in axle sleeve 1 the inside and support 2, workpiece spindle 3 passes workpiece spindle support 2 and is attached thereto, the front end of workpiece spindle 3 is disposed with magnetic coil 5, water fender 7, workpiece backer 8, it is characterized in that: between axle sleeve 1 and magnetic coil 5, fix and seal being provided with workpiece spindle end cap 4, be provided with at least one compressed air hose 6 in workpiece spindle end cap 4, the gas outlet of described compressed air hose 6 is positioned at the gap of magnetic coil 5 and workpiece spindle 3.
Operation principle of the present utility model is: the workpiece of processing is installed on the workpiece backer 8, with the emery wheel processing of polishing, grinding fluid is sprayed onto the place that workpiece backer 8 contacts with emery wheel, cool off workpiece and emery wheel with this.This moment, a large amount of grinding fluids was blocked by water fender 7; but still have a small amount of grinding fluid can enter into a place, space of magnetic coil 5 and workpiece spindle 3; open compressed air; because the outlet of compressed air hose 6 is positioned at a place; therefore a small amount of grinding fluid that can will enter wherein blows out, thereby play the effect of protection magnetic coil 5.
