A servo motor 402 is fixedly connected to the top of the protective box 401, and the output end of the servo motor 402 is fixedly connected to the top of the first rotating rod 406 through a coupling. A controller 2 is fixedly connected to the top of the workbench 1, and the output end of the controller 2 is electrically connected to the receiving end of the servo motor 402, and the output end of the controller 2 is electrically connected to the receiving end of the torque sensor 404.

[0024] Torque sensor 404, also known as torque sensor, torque sensor, torque sensor, torque meter, is divided into two categories: dynamic and static. Dynamic torque sensor can also be called torque sensor, torque speed sensor, non-contact torque sensor, rotation torque sensor, etc. Torque sensor is a detection of the perception of torsional torque on various rotating or non-rotating mechanical parts.

The surface of the destaticizing plate 520 abuts against the surface of the cleaning sleeve 513 .

[0027] The anti-static plate 520 is a static eliminator, and its principle is as follows. It consists of a high-voltage power generator and a discharge electrode, and ionizes the air into a large number of positive and negative ions through the high-voltage corona discharge at the tip, and then blows the large number of positive and negative ions to the surface of the object with wind to neutralize the static electricity, or directly brings the static eliminator close to the surface of the object to neutralize the static electricity.

[0028] The number of the driven gears 511 is two, and the two driven gears 511 are distributed in a ring array.

At this time, the test end of the brake passes through the installation slot 503, so that the test end of the brake fits with the test wheel 519. By starting the servo motor 402, the servo motor 402 rotates forward, thereby driving the first rotating rod 406 to rotate forward. The torque sensor 404 can be used to monitor the torque, so that the controller 2 can better control the output power of the servo motor 402. When the first rotating rod 406 rotates, the second rotating rod 405 will rotate synchronously, thereby driving the first bevel gear 403 to rotate, thereby driving the second bevel gears 508 on the left and right sides to rotate synchronously, so that the third rotating rod 507 rotates synchronously, and the test wheel 519 rotates. The brake is tested, and the test wheel 519 is rotated and locked by powering on and off the brake. The force on the third rotating rod 507 is fed back to the display instrument through the torque sensor 404 to complete the detection of the brake torque. S2. While the brake torque is being detected, the third rotating rod 507 rotates, which drives the driving gear 510 to rotate, thereby driving the driven gear 511 to rotate, so that the fourth rotating rod 509 drives the cam 514 to rotate, and the fourth rotating rod 509 drives the cleaning sleeve 513 to rotate. While the cleaning sleeve 513 rotates, the surface of the test wheel 519 is processed, so that when the test wheel 519 contacts the brake, the result of the brake locking is more accurate. When the cam 514 rotates, it drives the driven rod 517 to move back and forth left and right. Through the limiting of the U-shaped limiting plate 516, the moving frame 515 can reciprocate horizontally, so that the L-shaped plate 512 drives the anti-static plate 520 to reciprocate horizontally, and the static electricity on the surface of the cleaning sleeve 513 is processed, thereby improving the detection accuracy of the brake.

[0032] The present invention provides a brake torque measurement device and method. When working, two brakes are fixed on two fixing plates 502 on the left and right sides. At this time, the test end of the brake passes through the mounting slot 503, so that the test end of the brake fits with the test wheel 519. By starting the servo motor 402, the servo motor 402 rotates forward, thereby driving the first rotating rod 406 to rotate forward. The torque sensor 404 is set to monitor the torque, so that the controller 2 can better control the output power of the servo motor 402. When the first rotating rod 406 rotates, the second rotating rod 406 will rotate forward. 405 rotates synchronously, thereby driving the first bevel gear 403 to rotate, thereby driving the second bevel gears 508 on the left and right sides to rotate synchronously, so that the third rotating rod 507 rotates synchronously, so that the test wheel 519 rotates, and the brake is detected. The rotation and locking of the test wheel 519 are achieved by powering on and off the brake. The force on the third rotating rod 507 is fed back to the display instrument through the torque sensor 404 to complete the detection of the brake torque. The rotation of the third rotating rod 507 will drive the driving gear 510 to rotate, thereby driving the driven gear 51 1 is rotated, so that the fourth rotating rod 509 drives the cam 514 to rotate, and the fourth rotating rod 509 drives the cleaning sleeve 513 to rotate. When the cleaning sleeve 513 rotates, the surface of the test wheel 519 is processed. When the test wheel 519 is in use, the surface of the test wheel will generate static electricity due to friction with the brake, causing the surface of the test wheel to absorb dust. The cleaning sleeve 513 processes the dust absorbed on the surface of the test wheel 519, so that when the test wheel 519 contacts the brake, the result of the brake locking is more accurate. When the cam 514 rotates, it drives the driven rod 5 17 reciprocates left and right, and the U-shaped limiting plate 516 is limited to allow the movable frame 515 to reciprocate horizontally, so that the L-shaped plate 512 drives the anti-static plate 520 to reciprocate horizontally, and the cleaning sleeve 513 will discharge the static electricity on the surface of the test wheel 519 while processing the dust adsorbed on the surface of the test wheel 519. The anti-static plate 520 processes the static electricity on the surface of the cleaning sleeve 513 and also completes the processing of the static electricity on the surface of the test wheel 519. When the brake is locked, the influence of static electricity and dust is effectively reduced, and the detection accuracy of the brake is improved.

The first rotating rod (406) rotates At the same time, the second rotating rod (405) will be rotated synchronously, thereby driving the first bevel gear (403) to rotate, thereby driving the second bevel gears (508) on the left and right sides to rotate synchronously, so that the third rotating rod (507) is rotated synchronously, so that the test wheel (519) is rotated, and the brake is tested. The test wheel (519) is rotated and locked by powering on and off the brake. The force on the third rotating rod (507) is fed back to the display instrument through the torque sensor (404), and the brake torque is tested; S2. While the brake torque is being detected, the third rotating rod (507) rotates, which drives the driving gear (510) to rotate, thereby driving the driven gear (511) to rotate, so that the fourth rotating rod (509) drives the cam (514) to rotate, and the fourth rotating rod (509) drives the cleaning sleeve (513) to rotate. While the cleaning sleeve (513) rotates, the surface of the test wheel (519) is processed, so that when the test wheel (519) contacts the brake, the result of the brake locking is more accurate. When the cam (514) rotates, it drives the driven rod (517) to move back and forth left and right. Through the limitation of the U-shaped limiting plate (516), the moving frame (515) can reciprocate horizontally, so that the L-shaped plate (512) drives the anti-static plate (520) to reciprocate horizontally, and the static electricity on the surface of the cleaning sleeve (513) is processed, thereby improving the detection accuracy of the brake.
