Description

Technical Field

[0002] The brake disc, in simple terms, is a round disc that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc is equipped with mounting holes for fixing. The precise position of the brake disc mounting holes is the key parameter to ensure the accurate installation of the brake disc and the wheel. If the position of the brake disc mounting holes is inaccurate, it is easy to cause the brake disc to be subjected to forces at different angles and directions on the disc surface, causing a slight deviation between the center of gravity of the brake disc and the axis of the wheel. Therefore, before the brake disc is put into use, it is necessary to use a hole position calibration tool to calibrate the hole position of the brake disc.

[0003] However, in the existing equipment, the calibration disc without disassembly function can only calibrate four-hole brake discs or five-hole brake discs, and the calibration disc with the corresponding number of holes cannot be replaced according to needs, and the scope of use is limited. Therefore, a brake disc process hole position calibration tool is proposed. Utility Model Content

The inner wall of the sealing ring fits with the pressure rod 904. A sliding rod 902 is movably provided on the vertical plate 901, and a limit handle is fixedly provided at one end of the sliding rod 902. A spring is sleeved on the sliding rod 902, and one end of the spring fits with the vertical plate 901, and the other end of the spring fits with the limit handle. Each group of sliding rods 902 A same arc plate 908 is fixedly provided at one end, and the arc plate 908 is adapted to the through groove. A guide block 903 is fixedly provided on the inner wall of the arc plate 908. A conical column 905 is fixedly provided at the bottom of the pressure rod 904.

[0030] Working principle: when the calibration disk 2 of the corresponding hole position needs to be replaced, rotate the calibration disk 2 counterclockwise, the calibration disk 2 drives the plug post 4, and the plug post 4 drives the card block 5 to rotate in the card slot 3. When the card block 5 fits with the inner wall of one side of the card slot 3 and does not rotate, the calibration disk 2 can be removed and replaced by pulling it upwards.

After the expansion is completed, one end of the insertion rod 907 can be reinserted into the insertion hole of the pressure rod 904. The setting of the outer diameter adjustment structure 9 can realize the adjustment of the outer diameter of the calibration column 8, so that it can be suitable for the calibration of brake discs with different mounting hole diameters, thereby improving the practicality of the equipment.
