Description

Technical Field

[0001] This invention relates to the field of automotive testing technology, specifically to a device and method for continuous testing of the brake surface of automotive brake discs. Background Technology

[0002] A car brake disc, also called a brake pad, is an important component of a car's braking system. Brake discs are usually made of high-strength steel or aluminum alloy, which have good heat resistance and wear resistance. It is fixed to the wheel hub and rotates with the wheel. When the driver presses the brake pedal, the brake pads in the brake caliper are pressed against both sides of the brake disc, generating friction and thus slowing down the wheel's rotation. During the production and processing of brake discs, the brake surface of the brake disc needs to be inspected. The main inspections include the flatness of the brake surface, the width and thickness of the brake disc, and crack detection, to ensure that the processed brake disc meets safety and performance standards. However, existing automotive brake disc brake surface inspections are mostly conducted separately, requiring transfer between multiple inspection stations. Furthermore, some automotive brake discs have heat dissipation holes, which can lead to significant errors when using traditional instruments, and may even cause the inspection probe to break if it enters the holes. Therefore, we propose a continuous inspection device and method for automotive brake disc brake surfaces to solve the above problems. Summary of the Invention

An auxiliary crossbar is vertically mounted at the bottom end of the auxiliary longitudinal shaft. An adjusting crossbar is provided at the end of the auxiliary crossbar away from the auxiliary longitudinal shaft. An auxiliary fixed rod is movably engaged in the adjusting crossbar.

A transmission gear is fixedly installed at the drive end of the fourth motor, and the transmission gear and the transmission gear ring are meshed together.

[0010] As a preferred embodiment of the present invention, the planar detection component includes a rotating longitudinal rod, which is rotatably mounted on a mechanism base. A horizontal sliding outer frame is vertically mounted on the top end of the rotating longitudinal rod. A horizontal sliding inner seat is slidably engaged on the side of the horizontal sliding outer frame away from the rotating longitudinal rod.

The drive end of the third motor is fixedly mounted to the bottom end of the rotating longitudinal rod.

[0011] As a preferred embodiment of the present invention, the feeding mechanism includes two horizontally distributed linear electric rails. Each linear electric rail has an electric lifting rod on both sides of its top end. The electric lifting rod is fixedly installed on the top of a U-shaped bracket. The driving end of the electric lifting rod is fixedly installed on the top of the linear electric rail. Each driving end of the linear electric rail is fixedly installed with a connecting cross seat. Positioning components are fixedly installed on both sides of the bottom end of the two connecting cross seats.

[0012] As a preferred embodiment of the present invention, the positioning component includes a positioning cross frame, and positioning longitudinal rods are slidably engaged on both sides of the bottom end of the positioning cross frame. Anti-slip pads are fixedly installed on the outer bottom of the positioning longitudinal rods. A bidirectional telescopic rod is fixedly installed in the middle of the connecting cross seat, and the driving end of the bidirectional telescopic rod is fixedly installed with the corresponding positioning longitudinal rod.

[0013] A method for using a continuous detection device for the brake surface of an automotive brake disc includes the following steps: Step 1: First, select an auxiliary platform with multiple filler pillars according to the size of the brake disc and the position of the heat dissipation holes. Then, manually slide the horizontal sliding bracket according to the position of the inner groove on the auxiliary platform so that the end of the horizontal sliding bracket and the position of the inner groove are vertically aligned. Finally, use fastening bolts to fix it. The two conveyor belts are used to transport the car brake discs to be inspected. The car brake discs are transported to the bottom of the loading mechanism in sequence. The electric lifting rod is activated to control the two positioning components to descend, so that the positioning rod in one of the positioning components is placed in the middle of the car brake disc on one of the conveyor belts. Then, the bidirectional telescopic rod in one of the positioning components is extended, and the positioning rods on both sides are moved in opposite directions to expand the positioning of the car brake disc transported to the bottom of the loading mechanism. Then, the positioning component is raised, which drives the car brake disc to detach from the conveyor belt. The linear electric rail is activated to control the two positioning components to move horizontally, so that the expanded positioning car brake disc is moved to the top of the inspection mechanism for loading. At this time, the other positioning component corresponds to the other position of the conveyor belt for clamping and loading. Step 2: Activate multiple lifting cylinders to drive the lifting base frame to rise, thereby controlling multiple fixed support mechanisms to rise until the supporting balls and the lower surface of the car brake disc clamped on the positioning component contact each other, providing ball support for the car brake disc. Then, by simultaneously activating multiple telescopic cylinders to drive the sliding frame to move in opposite directions, so that the positioning wheel contacts the outer surface of the car brake disc, performing wheel positioning of the car brake disc. Afterward, release the clamps on the positioning component, and the car brake disc positioning support is loaded onto the multiple fixed support mechanisms. Step 3: Before adjusting the horizontal position of the car brake disc, turn on the second motor to drive the auxiliary longitudinal shaft to rotate the auxiliary crossbar and auxiliary fixed rod, so that the auxiliary fixed rod rotates to the top of the auxiliary platform. Adjust the position by manually sliding the auxiliary fixed rod and raising and lowering the auxiliary fixed rod so that the position of the auxiliary fixed rod is vertically aligned with the position of one of the filling columns on the auxiliary platform. Then, the first motor is turned on to drive the corresponding drive shaft to rotate. With the help of two transmission sprockets and transmission chains, the rotating shaft and the corresponding positioning wheel are driven to rotate, thereby controlling the horizontal rotation of the car brake disc of the positioning support. The horizontal position of the car brake disc is adjusted until the position of the auxiliary fixed rod and the position of one of the filling columns on the auxiliary platform are vertically aligned. Then, the second motor is turned on to rotate in the opposite direction, so that the auxiliary fixed rod is reset in the opposite direction and misaligned with the auxiliary platform. At the same time, multiple telescopic cylinders are activated to drive the sliding frame to move in the opposite direction, so that the positioning wheel is stored in the horizontal sliding bracket. Step 4: Lower multiple fixed support mechanisms to lower the car brake disc. At this time, multiple filling columns are precisely inserted into the heat dissipation holes on the car brake disc to fill them. Continue to lower multiple fixed support mechanisms. The end of the transverse sliding bracket passes through the inner groove and moves to the bottom of the auxiliary platform without affecting the subsequent rotation of the auxiliary platform. At this time, the car brake disc is positioned on the auxiliary platform. Step 5: During testing, turn on the third motor to drive the rotating rod to rotate, which will cause the horizontal sliding outer frame, the horizontal sliding inner seat, and the flat detector to rotate, so that the flat detector is moved above the car brake disc. Then, manually adjust the position of the bottom of the flat detector so that the bottom of the flat detector contacts the upper surface of the car brake disc. Subsequently, the transmission gear of the fourth motor is activated to rotate the transmission gear ring, which in turn rotates the connecting longitudinal tube and the auxiliary platform, thereby controlling the automatic rotation of the car brake disc. The fluctuation of the value on the flatness detector is observed to detect the flatness of the brake surface of the car brake disc. During this process, the electric telescopic rod is activated to control the horizontal movement of the flatness detector and adjust its position on the upper surface of the car brake disc for comprehensive inspection. During the inspection, because multiple filling columns fill the heat dissipation holes on the car brake disc, when the bottom end of the flatness detector contacts the heat dissipation hole position on the car brake disc, the bottom end detection probe of the flatness detector will not extend into the heat dissipation hole of the car brake disc and cause breakage or damage. Step Six: After the inspection is completed, reset the plane detector and the auxiliary stage to align the horizontal sliding bracket and the inner groove. Then, raise multiple fixed support mechanisms until the support ball and the lower surface of the car brake disc contact again. Move the multiple fixed support mechanisms upward again to move the inspected car brake disc below the positioning component for positioning and material removal. Then, control the two positioning components to move horizontally again to move the next car brake disc above the inspection mechanism for subsequent inspection, thereby achieving continuous inspection of multiple car brake discs.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a detection mechanism, the car brake disc is supported by wheel-type positioning ball bearings, thereby adjusting the horizontal position of the car brake disc. This ensures that the heat dissipation holes on the car brake disc correspond to the positions of multiple filling pillars on the auxiliary platform. This allows the multiple filling pillars to fill the heat dissipation holes on the car brake disc. When the bottom end of the flat detector contacts the position of the heat dissipation hole on the car brake disc, the detection probe at the bottom end of the flat detector will not extend into the heat dissipation hole and cause breakage or damage, thereby improving the detection efficiency of car brake discs with heat dissipation holes.

[0015] 2. By setting up a feeding mechanism and using a conveyor belt, two positioning components are used to expand and position the automotive brake disc, and continuous feeding and unloading are performed, which facilitates continuous testing of the automotive brake disc and further improves the testing efficiency of the automotive brake disc.

The two conveyor belts 4 are used to transport automotive brake discs to be detected, and sequentially transport the automotive brake discs to the bottom of the feeding mechanism 3. The feeding mechanism 3 includes two horizontally distributed linear electric rails 31. Each linear electric rail 31 has an electric lifting rod 311 on both sides of its top end. The electric lifting rod 311 is fixedly installed on the top of the U-shaped bracket 11. The drive end of the electric lifting rod 311 is fixedly installed on the top end of the linear electric rail 31. Each drive end of the linear electric rail 31 is fixedly installed with a connecting cross seat 32. Positioning components are fixedly installed on both sides of the bottom end of the two connecting cross seats 32. The two positioning components are controlled to descend by opening the electric lifting rod 311, and the two positioning components are controlled to move horizontally by opening the linear electric rail 31.

[0031] The positioning component includes a positioning cross frame 33. Positioning longitudinal rods 331 are slidably mounted on both sides of the bottom end of the positioning cross frame 33. Anti-slip pads 332 are fixedly installed on the outer bottom of the positioning longitudinal rods 331. A bidirectional telescopic rod 333 is fixedly installed in the middle of the connecting cross seat 32. The driving end of the bidirectional telescopic rod 333 and the corresponding positioning longitudinal rod 331 are fixedly installed. By opening the extension of the bidirectional telescopic rod 333 in one of the positioning components, the positioning longitudinal rods 331 on both sides are controlled to move in opposite directions, and the car brake disc transported to the bottom of the loading mechanism 3 is positioned outward. At this time, the car brake disc held on the other positioning component is located above the detection mechanism 2, and the car brake disc is loaded.

[0032] The testing mechanism 2 includes a mechanism base 21, which is fixedly installed on one side of the top of the base 1. A connecting longitudinal pipe 22 is fixedly installed in the middle of the top of the mechanism base 21. An auxiliary platform 23 is fixedly installed at the top of the connecting longitudinal pipe 22. Multiple filling columns 231 corresponding to the position of the brake disc heat dissipation holes are fixedly installed at the top of the auxiliary platform 23. The auxiliary platform 23 with multiple filling columns 231 is selected and installed according to the size of the brake disc and the position of the heat dissipation holes. A lifting base 24 is movably fitted on the outer side of the connecting longitudinal tube 22. Multiple connecting longitudinal rods 242 arranged in a circular array are fixedly installed on the top of the lifting base 24. A fixed support mechanism 25 is fixedly installed on the top of each connecting longitudinal rod 242. The multiple fixed support mechanisms 25 are arranged in a circular array. A flat detection component 5 is provided on one side of the mechanism base 21. Multiple lifting cylinders 241 arranged in a circular array are provided at the bottom of the lifting base 24. The multiple lifting cylinders 241 are fixedly installed on the mechanism base 21. The drive end of the multiple lifting cylinders 241 is fixedly installed at the bottom of the lifting base 24. By opening the multiple lifting cylinders 241, the lifting base 24 is driven to rise, thereby controlling the multiple fixed support mechanisms 25 to rise.

[0033] The fixed support mechanism 25 includes a horizontal sliding frame 251, which is fixedly installed on the top of the corresponding connecting vertical rod 242. A horizontal sliding bracket 252 is slidably opened in the horizontal sliding frame 251. An inner groove 232 corresponding to the horizontal sliding bracket 252 is opened on the auxiliary platform 23. A support ball 2521 is rolled and locked at the top of the horizontal sliding bracket 252 away from the horizontal sliding frame 251. Multiple fixed support mechanisms 25 rise until the support ball 2521 contacts the lower surface of the car brake disc held on the positioning member, so as to provide ball support for the car brake disc. The sliding bracket 252 has a sliding frame 253 movably attached to one end away from the sliding frame 251. The sliding frame 253 has a positioning wheel 254 rotatably attached to the other end away from the sliding frame 251. A telescopic cylinder 255 is fixedly installed in the sliding bracket 252. The drive end of the telescopic cylinder 255 is fixedly installed with the sliding frame 253. Then, by simultaneously opening multiple telescopic cylinders 255, the sliding frame 253 is driven to move towards each other, so that the positioning wheel 254 contacts the outer surface of the car brake disc, and the car brake disc is wheel-positioned. Then, the clamps on the positioning parts are released, and the car brake disc is positioned and supported on multiple fixed support mechanisms 25 for feeding. A fastening screw 2511 is fixedly installed at the top of the horizontal sliding frame 251. A fastening bolt 2512 is installed in the middle thread of the fastening screw 2511. The bottom end of the fastening bolt 2512 contacts the upper surface of the horizontal sliding bracket 252. According to the position of the inner groove 232 on the auxiliary platform 23, the horizontal sliding bracket 252 is manually slid so that the end of the horizontal sliding bracket 252 and the position of the inner groove 232 are vertically aligned. Then, the fastening bolt 2512 is used to fix it.

[0034] In one of the fixed support mechanisms 25, a rotating shaft 26 is fixedly installed in the middle of the positioning wheel 254. The rotating shaft 26 is rotatably installed in the corresponding sliding frame 253. A drive shaft 261 is provided on one side of the rotating shaft 26, and the drive shaft 261 is rotatably installed in the corresponding sliding frame 253. A transmission sprocket 262 is fixedly installed on the outer side of both the rotating shaft 26 and the drive shaft 261. A transmission chain 263 is movably sleeved on the outer side of the two transmission sprockets 262. A first motor 264 is fixedly installed on the side of the corresponding sliding frame 253 near the drive shaft 261. The drive end of the first motor 264 is fixedly installed on the bottom end of the corresponding drive shaft 261. By turning on the first motor 264, the corresponding drive shaft 261 is driven to rotate. With the transmission of the two transmission sprockets 262 and the transmission chain 263, the rotating shaft 26 and the corresponding positioning wheel 254 are driven to rotate, thereby controlling the horizontal rotation of the car brake disc of the positioning support and adjusting the horizontal position of the car brake disc.

[0035] In one of the fixed support mechanisms 25, an auxiliary longitudinal shaft 27 is rotatably mounted in the middle of the transverse sliding bracket 252. An auxiliary crossbeam 271 is vertically mounted at the bottom of each auxiliary longitudinal shaft 27. An adjusting transverse groove 2721 is provided at the end of the auxiliary crossbeam 271 away from the auxiliary longitudinal shaft 27. An auxiliary fixed rod 272 is movably engaged in the adjusting transverse groove 2721. Two first adjusting nuts 273 are threaded onto the outer side of the auxiliary fixed rod 272, located at the bottom and top of the auxiliary crossbeam 271 respectively. A second motor 274 is fixedly mounted in the middle of the top of the transverse sliding bracket 252. The drive end of the second motor 274 is fixedly mounted to the top of the auxiliary longitudinal shaft 27. Before adjusting the horizontal position of the car brake disc, the second motor 274 is turned on. The machine 274 drives the auxiliary longitudinal shaft 27 to rotate the auxiliary crossbar 271 and the auxiliary fixed rod 272, causing the auxiliary fixed rod 272 to rotate above the auxiliary platform 23. The position of the auxiliary fixed rod 272 is adjusted by manually sliding and raising the auxiliary fixed rod 272, so that the position of the auxiliary fixed rod 272 corresponds vertically with the position of one of the filling pillars 231 on the auxiliary platform 23. This allows the auxiliary fixed rod 272 to be used to position the horizontally adjusted car brake disc, so that the position of the heat dissipation holes on the car brake disc corresponds with the position of the auxiliary fixed rod 272. This also allows the position of the heat dissipation holes on the car brake disc to correspond with the positions of multiple filling pillars 231 on the auxiliary platform 23, so that the multiple filling pillars 231 can fill the heat dissipation holes on the car brake disc.

[0036] A transmission gear ring 221 is fixedly installed at the bottom of the connecting longitudinal tube 22. A fourth motor 222 is fixedly installed on the side of the mechanism base 21 near the transmission gear ring 221. A transmission gear 223 is fixedly installed at the drive end of the fourth motor 222. The transmission gear 223 and the transmission gear ring 221 are meshed together. By turning on the fourth motor 222, the transmission gear 223 is driven to rotate, thereby driving the connecting longitudinal tube 22 and the auxiliary platform 23 to rotate, thereby controlling the automatic rotation of the car brake disc, which facilitates the subsequent detection of the flatness of the brake surface of the car brake disc.

[0037] The planar detection component 5 includes a rotating longitudinal rod 51, which is rotatably mounted on the mechanism base 21. A horizontal sliding outer frame 52 is vertically mounted on the top of the rotating longitudinal rod 51. A horizontal sliding inner seat 53 is slidably engaged on the side of the horizontal sliding outer frame 52 away from the rotating longitudinal rod 51. An electric telescopic rod 531 is fixedly installed in the horizontal sliding outer frame 52. The drive end of the electric telescopic rod 531 is fixedly installed in the horizontal sliding inner seat 53. A planar detector 54 is slidably inserted in the middle of the horizontal sliding inner seat 53. Two second adjusting nuts 541 are threaded on the outer side of the planar detector 54. The two second adjusting nuts 541 are located at the bottom and top of the horizontal sliding inner seat 53, respectively. A third motor 55 is fixedly installed on the side of the rotating longitudinal rod 51 closest to it. The drive end of the third motor 55 is fixedly installed in the bottom of the rotating longitudinal rod 51. During detection, the third motor 55 is turned on to drive the rotating longitudinal rod 51 to rotate, thereby rotating the horizontal sliding outer frame. 52. The inner sliding seat 53 and the flat surface detector 54 rotate, moving the flat surface detector 54 above the car brake disc. The position of the bottom end of the flat surface detector 54 is manually adjusted so that the bottom end of the flat surface detector 54 contacts the upper surface of the car brake disc. Then, the car brake disc is controlled to rotate automatically, and the fluctuation of the value on the flat surface detector 54 is observed to detect the flatness of the brake surface of the car brake disc. During this process, the electric telescopic rod 531 is activated to control the horizontal movement of the flat surface detector 54 and adjust the position of the flat surface detector 54 on the upper surface of the car brake disc for comprehensive detection of the upper surface of the car brake disc. During the detection, because multiple filling columns 231 fill the heat dissipation holes on the car brake disc, when the bottom end of the flat surface detector 54 contacts the heat dissipation hole position on the car brake disc, the detection probe at the bottom end of the flat surface detector 54 will not extend into the heat dissipation hole on the car brake disc and cause breakage or damage.

[0038] A method for using a continuous detection device for the brake surface of an automotive brake disc includes the following steps: Step 1: First, select and install the auxiliary platform 23 with multiple filler pillars 231 according to the size of the brake disc and the position of the heat dissipation hole. Then, according to the position of the inner groove 232 on the auxiliary platform 23, manually slide the horizontal sliding bracket 252 so that the end of the horizontal sliding bracket 252 and the position of the inner groove 232 are vertically aligned. Then, use the fastening bolt 2512 to fix it. The two conveyor belts 4 are used to transport the car brake discs to be inspected. The car brake discs are transported to the bottom of the loading mechanism 3 in sequence. By opening the electric lifting rod 311, the two positioning parts are lowered so that the positioning rod 331 in one of the positioning parts is placed in the middle of the car brake disc on the one-position conveyor belt 4. Then, the bidirectional telescopic rod 333 in one of the positioning parts is extended, and the two positioning rods 331 on both sides are moved in opposite directions to expand the positioning of the car brake disc transported to the bottom of the loading mechanism 3. Then, the positioning parts are raised, which drives the car brake disc to get off the conveyor belt 4. The linear electric rail 31 is opened to control the two positioning parts to move horizontally so that the expanded positioning car brake disc is moved to the top of the inspection mechanism 2 for loading. At this time, the other positioning part corresponds to the other position conveyor belt 4 for clamping and loading. Step 2: Activate multiple lifting cylinders 241 to drive the lifting base frame 24 to rise, thereby controlling multiple fixed support mechanisms 25 to rise until the supporting balls 2521 contact the lower surface of the car brake disc clamped on the positioning component, providing ball support for the car brake disc. Then, by simultaneously activating multiple telescopic cylinders 255, drive the sliding frame 253 to move towards each other, so that the positioning wheel 254 contacts the outer surface of the car brake disc, performing wheel positioning of the car brake disc. Then, release the clamps on the positioning component, and the car brake disc positioning support is loaded onto the multiple fixed support mechanisms 25. Step 3: Before adjusting the horizontal position of the car brake disc, turn on the second motor 274 to drive the auxiliary longitudinal shaft 27 to rotate the auxiliary crossbar 271 and the auxiliary fixed rod 272, so that the auxiliary fixed rod 272 rotates to the top of the auxiliary platform 23. Adjust the position by manually sliding the auxiliary fixed rod 272 and raising and lowering the auxiliary fixed rod 272 so that the position of the auxiliary fixed rod 272 corresponds vertically to the position of one of the filling columns 231 on the auxiliary platform 23. Subsequently, the first motor 264 is turned on, driving the corresponding drive shaft 261 to rotate. In conjunction with the transmission of the two transmission sprockets 262 and the transmission chain 263, the rotating shaft 26 and the corresponding positioning wheel 254 are driven to rotate, thereby controlling the positioning support of the car brake disc to rotate horizontally and adjusting the horizontal position of the car brake disc until the position of the auxiliary fixed rod 272 and the position of one of the filling columns 231 on the auxiliary platform 23 are vertically aligned. Then, the second motor 274 is turned on to rotate in the opposite direction, causing the auxiliary fixed rod 272 to reset in the opposite direction and misalign with the auxiliary platform 23. At the same time, multiple telescopic cylinders 255 are turned on to drive the sliding frame 253 to move in the opposite direction, so that the positioning wheel 254 is stored in the horizontal sliding bracket 252. Step 4: Lower multiple fixed support mechanisms 25 to lower the car brake disc. At this time, multiple filling columns 231 are precisely inserted into the heat dissipation holes on the car brake disc to fill them. Continue to lower multiple fixed support mechanisms 25. The end of the transverse sliding bracket 252 passes through the inner groove 232 and moves to the bottom of the auxiliary platform 23 without affecting the subsequent rotation of the auxiliary platform 23. At this time, the car brake disc is positioned on the auxiliary platform 23. Step 5: During testing, turn on the third motor 55 to drive the rotating rod 51 to rotate, which in turn drives the horizontal sliding outer frame 52, the horizontal sliding inner seat 53, and the plane detector 54 to rotate, so that the plane detector 54 is moved above the car brake disc. Then, manually adjust the position of the bottom of the plane detector 54 so that the bottom of the plane detector 54 contacts the upper surface of the car brake disc. Subsequently, by activating the fourth motor 222 to drive the transmission gear 223 to rotate the transmission gear ring 221, thereby driving the connecting longitudinal tube 22 and the auxiliary platform 23 to rotate, thus controlling the automatic rotation of the car brake disc. The fluctuation of the value on the flatness detector 54 is observed to detect the flatness of the brake surface of the car brake disc. During this process, the electric telescopic rod 531 is activated to control the horizontal movement of the flatness detector 54 and adjust the position of the flatness detector 54 on the upper surface of the car brake disc so as to conduct a comprehensive inspection of the upper surface of the car brake disc. During the inspection, because multiple filling columns 231 fill the heat dissipation holes on the car brake disc, when the bottom end of the flatness detector 54 contacts the heat dissipation hole position on the car brake disc, the detection probe at the bottom end of the flatness detector 54 will not extend into the heat dissipation hole on the car brake disc and cause breakage or damage. Step 6: After the test is completed, reset the plane detector 54 and the auxiliary platform 23 to make the positions of the horizontal sliding bracket 252 and the inner groove 232 correspond. Then, raise multiple fixed support mechanisms 25 until the support ball 2521 and the lower surface of the car brake disc contact again. Then, move multiple fixed support mechanisms 25 upward again to move the tested car brake disc to the bottom of the positioning component for positioning and unloading. Then, control the two positioning components to move horizontally again to move the next car brake disc to the top of the testing mechanism 2 for subsequent testing, thereby realizing the continuous testing of multiple car brake discs.

10. A method of using the continuous detection device for the brake surface of an automotive brake disc as described in claim 9, characterized in that, Includes the following steps: Step 1: First, select an auxiliary platform (23) with multiple filler columns (231) according to the size of the brake disc and the position of the heat dissipation holes. Then, according to the position of the inner groove (232) on the auxiliary platform (23), manually slide the horizontal sliding bracket (252) so that the end of the horizontal sliding bracket (252) and the position of the inner groove (232) are vertically aligned. Then, use fastening bolts (2512) to fix it. The two conveyor belts (4) are used to transport the car brake discs to be tested. The car brake discs are transported to the bottom of the loading mechanism (3) in sequence. The two positioning parts are lowered by opening the electric lifting rod (311) so that the positioning rod (331) in one of the positioning parts is placed in the middle of the car brake disc on one of the position conveyor belts (4). Then, the bidirectional telescopic rod (333) in one of the positioning parts is extended, and the positioning rods (331) on both sides are moved in opposite directions to expand the positioning of the car brake disc transported to the bottom of the loading mechanism (3). Then, the positioning parts are raised to drive the car brake disc to get off the conveyor belt (4), and the linear electric rail (31) is opened to control the two positioning parts to move horizontally so that the expanded positioning car brake disc is moved to the top of the testing mechanism (2) for loading the car brake disc. At this time, the other positioning part corresponds to the other position conveyor belt (4) so ​​as to clamp and load the car brake disc. Step 2: Activate multiple lifting cylinders (241) to drive the lifting base frame (24) to rise, thereby controlling multiple fixed support mechanisms (25) to rise until the supporting ball bearings (2521) and the lower surface of the car brake disc clamped on the positioning component are in contact, providing ball bearing support for the car brake disc. Then, by activating multiple telescopic cylinders (255) simultaneously, drive the sliding frame (253) to move towards each other, so that the positioning wheel (254) is in contact with the outer surface of the car brake disc, performing wheel positioning for the car brake disc. Then, release the clamping on the positioning component, and the car brake disc positioning support is loaded onto the multiple fixed support mechanisms (25). Step 3: Before adjusting the horizontal position of the car brake disc, turn on the second motor (274) to drive the auxiliary longitudinal shaft (27) to rotate the auxiliary crossbar (271) and the auxiliary fixed rod (272), so that the auxiliary fixed rod (272) rotates to the top of the auxiliary platform (23), and adjusts the position by manually sliding the auxiliary fixed rod (272) and raising and lowering the auxiliary fixed rod (272) so that the position of the auxiliary fixed rod (272) is vertically aligned with the position of one of the filling columns (231) on the auxiliary platform (23); Subsequently, the first motor (264) is turned on to drive the corresponding drive shaft (261) to rotate. With the transmission of the two transmission sprockets (262) and the transmission chain (263), the rotating shaft (26) and the corresponding positioning wheel (254) are driven to rotate, thereby controlling the positioning support of the car brake disc to rotate horizontally and adjusting the horizontal position of the car brake disc until the position of the auxiliary fixed rod (272) and the position of one of the filling columns (231) on the auxiliary platform (23) are vertically aligned. Then, the second motor (274) is turned on to rotate in the opposite direction, so that the auxiliary fixed rod (272) is reset in the opposite direction and misaligned with the auxiliary platform (23). At the same time, multiple telescopic cylinders (255) are turned on to drive the sliding frame (253) to move in the opposite direction, so that the positioning wheel (254) is stored in the horizontal sliding bracket (252). Step 4: Lower multiple fixed support mechanisms (25) to lower the car brake disc. At this time, multiple filling columns (231) are precisely inserted into the heat dissipation holes on the car brake disc for filling. Continue to lower multiple fixed support mechanisms (25). The end of the transverse sliding bracket (252) passes through the inner groove (232) and moves to the bottom of the auxiliary platform (23) without affecting the subsequent rotation of the auxiliary platform (23). At this time, the car brake disc is positioned on the auxiliary platform (23). Step 5: During the test, turn on the third motor (55) to drive the rotating rod (51) to rotate, which will drive the horizontal sliding outer frame (52), the horizontal sliding inner seat (53) and the plane detector (54) to rotate, so that the plane detector (54) is moved above the car brake disc. The bottom of the plane detector (54) is manually adjusted so that the bottom of the plane detector (54) contacts the upper surface of the car brake disc. Subsequently, by turning on the fourth motor (222) to drive the transmission gear (223) to drive the transmission gear ring (221) to rotate, thereby driving the connecting longitudinal tube (22) and the auxiliary platform (23) to rotate, thereby controlling the car brake disc to rotate automatically, observing the fluctuation of the value on the plane detector (54), and detecting the flatness of the brake surface of the car brake disc. During this period, the electric telescopic rod (531) is turned on to control the plane detector (54) to move horizontally and adjust the position of the plane detector (54) on the upper surface of the car brake disc so as to conduct a comprehensive inspection of the upper surface of the car brake disc. During the inspection, since multiple filling columns (231) fill the heat dissipation holes on the car brake disc, when the bottom end of the plane detector (54) contacts the heat dissipation hole position on the car brake disc, the detection probe at the bottom end of the plane detector (54) will not extend into the heat dissipation hole on the car brake disc and cause breakage or damage. Step 6: After the test is completed, reset the plane detector (54) and reset the auxiliary stage (23) so that the horizontal sliding bracket (252) and the inner groove (232) are in the same position. Then, raise multiple fixed support mechanisms (25) until the support ball (2521) and the lower surface of the car brake disc are in contact again. Then, move multiple fixed support mechanisms (25) up again to move the tested car brake disc to the bottom of the positioning component for positioning and material removal. Then, control the two positioning components to move horizontally again to move the next car brake disc to the top of the testing mechanism (2) for subsequent testing, thereby realizing the continuous testing of multiple car brake discs.
