Description

Technical Field

[0001] The utility model relates to the technical field of roller processing equipment, in particular to a positioning disc for roller grinding. Background Art

[0002] When the end face of a roller is ground, the roller needs to be fixed. Most of the existing fixing methods are to convey the roller to the positioning disc through a conveying channel, and a roller bin is opened on the positioning disc to fix the roller, and then a grinding device is used to grind its end. For example, a Chinese patent discloses a grinding device on a conical roller ball base surface grinding machine, which includes a conical roller, a separator disc and a grinding wheel. The cylinder bracket is fixed on the base, and the guide rod thin cylinder is fixed on the cylinder bracket. An oil stone holder is provided on the guide rod of the guide rod thin cylinder, a proximity switch is installed on the guide rod tubular cylinder, an oil stone is installed on the oil stone holder, and a positioning pin is arranged between the cylinder bracket and the base.

[0003] However, the disadvantage of this method is that the roller rotates during the grinding process, wears against the roller bin, and the long-term wear will cause the deformation of the roller bin, further reducing the positioning effect on the roller and resulting in a decrease in the processing yield. Summary of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a positioning disc for roller grinding that can avoid wear between the roller and the roller bin.

[0005] The embodiment of the utility model specifically adopts the following technical scheme to achieve the above purpose: a positioning disc for roller grinding, including a disc body, a roller bin is arranged on the side wall of the disc body, a clamping boss connected to the machine tool is arranged in the middle of the disc body, the disc body includes a base plate, a limit pressing plate is arranged outside the base plate, and a bushing corresponding to the position of the roller bin is arranged on the limit pressing plate.

[0006] As a further improvement of the above technical scheme:

[0007] A placement cavity for placing the limit pressing plate is arranged on the side wall of the base plate, and an avoidance groove is arranged in the middle of the placement cavity.

[0008] A clamping plate corresponding to the position of the avoidance groove is arranged in the middle of the limit pressing plate, and a positioning bolt connecting the clamping plate to the base plate is arranged on the clamping plate.

[0009] The number of the roller bins is multiple, and the multiple roller bins are evenly distributed along the circumferential direction of the base plate. Each roller bin is in a frustum shape and the diameter gradually decreases from the surface of the base plate towards the inside.

[0010] The number and position of the bushings correspond to those of the roller bins, and the bushings are detachably connected to the limit pressing plate.

[0011] The lower end of the bushing extends into the roller bin, and a positioning post that abuts against the limiting pressing plate is provided at the upper end. A positioning platform corresponding to the position of the positioning post is provided on the side wall of the limiting pressing plate.
