Description

Technical Field

[0001] The utility model relates to the technical field of disc brake parallelism detection, in particular to a disc brake parallelism detection device. Background Art

[0002] Disc brakes are a common braking system that consists of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking is required, the brake caliper clamps the disc to achieve the purpose of braking.

[0003] For example, a disc brake disc flatness tester with authorization announcement number "CN219914302U" avoids collisions and contact with the disc during assembly and disassembly, improving safety. However, when limiting the position of the disc, the disc's inner ring is limited by ground plates on both sides, while the other two sides of the inner ring are not limited. This causes the disc to easily shake during testing, resulting in inaccurate flatness testing of the disc, which reduces work quality. Furthermore, this disc flatness tester requires workers to frequently move the ejector pin during testing, increasing their workload. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the ground plates on both sides are limited by the inner ring of the disc brake disc, while the other two sides of the inner ring of the disc brake disc are not limited, which causes the disc brake disc to shake easily during the detection process, thereby making the disc brake disc flatness detection inaccurate, thereby reducing the work quality and requiring workers to frequently move the position of the ejector pin when detecting the flatness of the disc, thereby increasing the labor force of the workers at work. A disc brake parallelism detection device is proposed to solve the problem that the ground plates on both sides are limited by the inner ring of the disc brake disc, while the other two sides of the inner ring of the disc brake disc are not limited,

The upper end of the base is installed with a moving mechanism. The front end of the box body is slidably connected to the box door through a hinge. The box body is fixedly connected to the first servo motor through a bracket. The output shaft of the first servo motor is connected to the round shell through a reduction box.

[0007] Preferably, the limiting mechanism includes a second servo motor, which is fixedly connected to the circular shell through a bracket, and the output shaft of the second servo motor is connected to the rotating shaft of the disc through a reduction gear box. The disc is rotatably connected to the circular shell through the rotating shaft, and the inner wall of the disc is slidingly connected to a plurality of protrusions, and the outer walls of the plurality of protrusions are fixedly connected to the rod body.

[0008] Preferably, the ends of the rods are fixedly connected to the blocks, and the inner walls of the blocks are connected to the bolt threads.

[0009] Preferably, the moving mechanism includes a shell, the lower end of the shell is fixedly connected to the base, the shell is fixedly connected to the third servo motor through a bracket, the output shaft of the third servo motor is connected to the rotating shaft of the gear through a reduction gear box, the gear is rotatably connected to the shell through the rotating shaft, and the outer wall of the gear is engaged with the rack.

The test gauge 8 can measure the specific flatness through the contact between the ejector pin 9 and the disc brake disc.

[0026] Working principle:

[0027] When the parallelism of the disc brake needs to be tested, the disc brake disc is placed in the block 205, and then the external power supply of the second servo motor 201 is turned on and started. The second servo motor 201 drives the disc 202 to rotate, and the disc 202 drives the protrusion 203 to move through the slide groove (because the outer wall of the protrusion 203 is relatively smooth, thereby reducing the friction between the protrusion 203 and the disc 202, thereby preventing damage to the protrusion 203 and the disc 203). The four protrusions 203 all drive the rod body 204 to move outward, thereby moving the four blocks 205. The inner walls of the four blocks 205 all contact the inner ring of the disc brake disc, thereby limiting the disc brake disc on the four blocks 205, and then respectively tighten the bolts 206 on the four blocks 205 so that the ends thereof are pressed against the disc brake disc, thereby reinforcing the limit of the disc brake disc, thereby making the limit of the disc brake disc more stable;

[0028] Then, the external power supply of the third servo motor 302 is connected and started. The third servo motor 302 drives the gear 303 to rotate. The gear 303 engages with the rack 304 and drives the rack 304 to move downward. The rack 304 drives the test table 8 to move downward and drives the ejector pin 9 to move downward. After the lower end of the ejector pin 9 contacts the limited disc brake disc, the third servo motor 302 is turned off. In the above manner, the ejector pin 9 is moved downward and contacts the disc brake disc. The external power supply of the servo motor 6 is connected and started. The first servo motor 6 drives the circular shell 7 to rotate slowly, and the limited disc brake disc rotates slowly. During the rotation of the disc brake disc, the ejector pin 9 contacts the disc brake disc and detects the flatness of the disc brake disc. The ejector pin 9 transmits the detection data value of the disc brake disc flatness to the test table 8 and displays it on the display screen of the test table 8. The worker can record the data.

[0029] After the flatness test on the disc brake disc is completed, the first servo motor 6 is turned off, and then the third servo motor 302 is started to move the ejector pin 9 upward to reset. After the ejector pin 9 is reset, the third servo motor 302 is turned off, and then the second servo motor 201 is used to cancel the fixation of the disc brake disc, and then it is removed from the block 205 and turned 180 degrees before limiting the disc brake disc on the block 205. Then, the third motor 302 is used to make the ejector pin 9 contact the disc brake disc again and then perform a flatness test on the other side of the disc brake disc. After the flatness test of the disc brake disc is completed, the first servo motor 6 is turned off, and then the third servo motor 302 is used to move the ejector pin 9 upward to reset. Then, the limit of the disc brake disc on the block 205 is canceled according to the above method, and the tested disc brake disc is manually removed from the block 205 and transported to the next process. The above method is used to complete the test of the flatness of the disc brake disc.
