The present invention secures the support device on both ends of the rotating roll when grinding the rotating processing roll in the roll grinding machine to prevent the roll from rolling and to prevent the wear of both center parts installed in the polishing machine by smoothing the rotation of the roll. The present invention relates to abrasion preventing device of both centers in the processing of rotary roll of grinding machine.

This device separates the device supporting side to the center of spindle and tailstock by fixing part and rotating part to prevent center abrasion and to prevent the centerline from being disturbed by center wear. And to improve the degree of cylindricality and to prevent degradation of the surface quality.

In the general roll grinding machine 10, the workpiece is fixed to the main shaft 11, and the center hole is machined in the tailstock 12, and the center hole is used as the rotation center, but the roll grinding machine 10 In order to prevent the brushing phenomenon in which the roll 14 moves from side to side on the headstock 11 and tailstock 12 by using a method of supporting the roll neck NECK rather than the fixed support in the PED. Supporting polishing has been carried out using a stopper operated by plastic between the center and the roll 14.

However, when the support polishing with the plastic is pushed severely from the tailstock (12) side to the main shaft (11) side, the plastic and the center is worn, the setting work is performed for the accuracy of roundness and cylinder degree. The roundness and the cylinder caused by the disordered centerline of the workpiece due to the defect also causes the defect, and if loosely supported, the surface processing quality is deteriorated due to the tipping of the roll.

Therefore, the present invention was devised to solve this problem in consideration of the above-mentioned problems. The wear of both center parts during the rotary rolling roll processing of the grinding machine, which prevents center wear and facilitates roll support by removing heat generation at the joint part The object is to provide a prevention device.

In order to achieve the above object, the present invention assembles a fixed part fixed to a center, a bearing, and a rotating part that is in close contact with a roll end and rotates like a roll, thereby providing a wear protection window of both center parts during a rotary processing roll processing of the polishing machine. By.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the conventional roll grinding machine 10 provided with the tailstock 11 on one side and the tailstock 12 provided with a handle 13 on the other side

At each of the headstock 11 and the tailstock 12, the front end portion of each of the support body 20, 20a for firmly supporting both ends of the rotary processing roll 14, but the headstock 11 side The support body 20a and the support body 20a on the tail stock 12 side of the support body 20 are provided with the respective turning tools 21 and 21a on both sides. The fasteners 22 and 22a machined by the inclination of the outer light inner diameter were inserted and installed, and the bearings 23 and 23a were placed between the fasteners 22 and 22a and the rotary balls 21 and 21a. It is installed by fastening the stop rings 24, 24a to both ends of the bearings 23, 23a.

Referring to the effect of the present invention configured as described above are as follows.

The present invention is first, as shown in Figures 2 and 3, the fixture 22 processed as a slope of the center with a synthetic resin material in order to prevent the impact on the center of the main shaft 11 and the tailstock 12, The bearings 23 and 23a are fitted to the rotating holes 21 and 21a so as to smoothly rotate the rotating holes 21 and 21a, and the bearings 23 and 23a are provided at both ends of the bearings 23 and 23a. The stoppers 24 and 24a are fastened to prevent the positional deviation of the rotary balls 21, 21a and the fixtures 22, 22a and the bearings 23, 23a. It became.

Rotation after the main body of the main shaft (11) side fixture body 20 and the tailstock 12 side fixture body (20a) is installed in the center of the main shaft 11 and the center of the tail stock 12. After transporting the processing roll 14 by a crane or the like and laying it on the roll polishing machine 10, the support body body 20a on the tailstock 12 side is supported by one hand and coupled to the center of the tailstock 12. The tailstock 12 is conveyed to the construction table 11 side by turning the handle 13 provided in (12).

When the tailstock 12 is moved to the main shaft 11 side by a predetermined distance as described above, both ends of the rotary processing roll 14 is fixed to the fixtures 22, 22a installed in the rotor 21, 21a. While being coupled to the rotary processing roll 14 to maintain the level.

At this time, since the rotary spheres 21 and 21a are in contact with both sides of the rotary processing roll 14 to rotate together in the direction of rotation of the rotary processing roll 14, good roundness and cylinder degree of the rotary processing roll 14 are achieved. Also, the friction does not occur with the center part of the rotary processing roll 14, the main shaft 11, and the tailstock 12 generated while rotating, and there is no fear of wear, and the main shaft is loosely supported. (11) and the tailstock (12) is a useful design that can protect the polishing machine and improve the quality of the rotational processing roll because it does not cause tilting and shaking.
