Description

Technical Field

[0001] The utility model relates to the technical field of a brake disc punching and marking precise positioning device, in particular to a brake disc punching and marking precise positioning device. Background Art

[0002] The positioning device is a device that is generally installed on the punching and marking equipment during the brake disc processing to fix the brake disc and then cooperate with the punching and marking equipment to perform orderly punching and marking processing on the brake disc.

[0003] Existing positioning and fixing clamps for drilling brake discs are generally limited to fixing the brake discs, so that they can only be used with drilling and marking equipment whose drilling drill can move accurately. When the positioning and fixing clamp needs to be used with equipment that the drilling drill cannot move, it is usually only possible to manually rotate the brake disc to the corresponding position after drilling a hole, and then position and fix it before drilling. Manual movement may cause the drilled holes to be offset or misplaced, making the processed brake disc unusable, which reflects the low adaptability of traditional positioning and fixing clamps. Utility Model Content

When the positioning and fixing clamp needs to be used with a device whose drilling drill cannot be moved, the brake disc can usually only be manually rotated to a corresponding position after drilling a hole, and then the drilling operation can be performed after it is positioned and fixed. Manual movement of the brake disc may cause the drilled hole to be offset or misaligned, thereby making the processed brake disc unusable. This reflects the problem that the conventional positioning and fixing clamps have low adaptability, and a device for accurately positioning the holes and marking the brake discs is proposed.
