Description

Technical Field

[0001] This utility model relates to the technical field of flatness testing devices, specifically a flatness testing device for brake disc manufacturing and processing. Background Technology

[0002] Electromagnetic power failure brakes are ideal automated actuators in modern industry, widely used in machinery in metallurgy, hoisting, construction, chemical, food, machine tools, and packaging to achieve rapid stopping and accurate positioning. They can be used for safety (risk prevention) braking during power failures. The brake disc is an essential component of the brake. To ensure the braking effect, the surface flatness of the brake disc needs to be tested after production. Only brake discs that pass the flatness test can be shipped for use. Traditionally, flatness testing is done manually by using a dial indicator to select points on the disc, which is inefficient. To improve this, a flatness testing device for brake disc production is proposed.

[0003] A flatness testing device, as disclosed in authorization announcement number CN218724073U, includes a base, a lifting seat on the top of the base, an auxiliary moving block inside the lifting seat, a motor at the bottom of the lifting seat, a screw at the drive end of the motor, the other end of the screw passing through the top of the auxiliary moving block for rotatable connection, a fixing rod inside the lifting seat located on one side of the screw, the two ends of the fixing rod being fixedly connected to the bottom and top of the lifting seat, an opening on one side of the lifting seat, a sleeve passing through the opening on one side of the auxiliary moving block, an extension rod inside the sleeve, a detection component at the end of the extension rod away from the sleeve, and a dual-drive motor at the bottom of the base, with first connecting rods at both ends of the dual-drive motor.

[0004] Although it achieves the design of telescopic device, when an object blocks the detection device and it cannot get close to the wall, the detection device can be detected when the telescopic device is installed and the extension rod is extended to a suitable position. When it is in a suitable position, it can be fixed by loosening or tightening the screw. When the extension rod needs to be extended or retracted, the screw is loosened, and when it needs to be fixed, the screw is tightened. It can effectively achieve the effects of small size and flexible use.

[0005] However, this does not solve the problem that existing flatness testing devices are not conducive to convenient linkage and external expansion center clamping and fixing of the brake disc during use, and are not conducive to circumferential testing of the brake disc, thus affecting the testing efficiency of brake disc flatness. Utility Model Content

[0006] The purpose of this utility model is to provide a flatness testing device for brake disc manufacturing and processing, so as to solve the problem in the above-mentioned flatness testing device that is not convenient for linking and expanding the center clamping and fixing the brake disc, which is not conducive to the circumferential testing of the brake disc and affects the testing efficiency of brake disc flatness.

[0007] To address the technical problems mentioned in the background section above, some embodiments of this application provide a flatness testing device for brake disc manufacturing, including a testing platform and a limiting ring. The limiting ring is installed at the top of the testing platform, and a bearing ring is movably installed inside the limiting ring. A toothed ring is installed at the top of the bearing ring. A servo motor is installed on the outer wall of the testing platform, and a gear is installed at the output end of the servo motor, with the gear meshing with the toothed ring.

[0008] Furthermore, an integrated frame is symmetrically mounted on the top of the toothed ring, and a placement block is installed at the center of the inside of the testing station.

[0009] Furthermore, three sets of equally spaced bearing blocks are installed at the top of the placement block, and a cylinder is installed at the bottom of the placement block.

[0010] Furthermore, each integrated frame has a lead screw movably installed inside, and each integrated frame has a drive motor at its top, with the output end of the drive motor connected to the lead screw.

[0011] Furthermore, the surface of the lead screw is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the lead screw.

[0012] Furthermore, each threaded sleeve is equipped with a connecting plate on its sidewall, and each connecting plate is equipped with a dial indicator at its bottom.

[0013] Furthermore, a push arm is installed at the output end of the cylinder, and the push arm passes through the placement block and is slidably connected to the placement block.

[0014] Furthermore, the push arm has three sets of linkage arms at equal intervals on its side wall, and the linkage arms are movably connected to the push arm.

[0015] Furthermore, each of the connecting arms is provided with a clamping arm at the end away from the push arm, and the clamping arm is movably connected to the connecting arm.

[0016] Furthermore, each of the clamping arms is provided with a pin at the end near the bearing block, and the clamping arm is movably connected to the bearing block through the pin.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the flatness detection device not only realizes the convenient linkage outward expansion center clamping and fixing of the brake disc, which facilitates the circumferential detection of the brake disc, but also improves the detection efficiency.

[0018] The brake disc to be tested is placed over the three sets of clamping arms. The cylinder is activated, causing the push arm to move. The push arm then rotates the linkage arm. Supported by the bearing block, the linkage arm rotates the clamping arms around the pivot, causing the three sets of clamping arms to rotate outwards. The clamping arms then clamp and fix the brake disc from the inside. To ensure the brake disc is level, after clamping, a level is placed on the surface of the brake disc to check its levelness. Then, the drive motor is activated, causing the lead screw to rotate. The lead screw moves the threaded sleeve downwards, and the threaded sleeve, through the connecting plate, moves the dial indicator downwards. The system moves the dial indicator to contact the surface of the brake disc. Then, the servo motor is activated, which drives the gear to rotate. The gear drives the gear ring to rotate, which in turn drives the integrated frame, connecting plate, and dial indicator to rotate. This causes the dial indicator to move on the upper surface of the brake disc. If the dial indicator moves to an uneven position, it will generate data fluctuations. This data is sent to the computer through a logic processor, and the computer generates a signal to mark whether the brake disc is qualified. This system realizes convenient linkage, external expansion, and center clamping to fix the brake disc, which facilitates the circumferential inspection of the brake disc and improves the efficiency of brake disc flatness inspection.

[0033] Please see Figures 1 to 5 This utility model provides an embodiment of a flatness testing device for brake disc manufacturing and processing, comprising a testing platform 1 and a limiting ring 19. The limiting ring 19 is installed at the top of the testing platform 1, and a bearing ring 18 is movably installed inside the limiting ring 19. A gear ring 4 is installed at the top of the bearing ring 18. A servo motor 2 is installed on the outer wall of the testing platform 1, which serves as a power drive. A gear 3 is installed at the output end of the servo motor 2, and the gear 3 meshes with the gear ring 4. An integrated frame 5 is symmetrically installed at the top of the gear ring 4. A placement block 6 is installed at the center position inside the testing platform 1. Three sets of bearing blocks 14 with equal spacing are installed at the top of the placement block 6. A cylinder 12 is installed at the bottom of the placement block 6, which serves as a power drive.

[0034] The integrated frame 5 has a lead screw 10 installed inside, and a drive motor 8 is installed at the top of the integrated frame 5. The drive motor 8 plays the role of power driving, and the output end of the drive motor 8 is connected to the lead screw 10.

[0035] The surface of the lead screw 10 is fitted with a threaded sleeve 9, and the threaded sleeve 9 is threadedly connected to the lead screw 10. A connecting plate 11 is installed on the side wall of the threaded sleeve 9, and a dial indicator 7 is installed at the bottom of the connecting plate 11. A push arm 13 is installed at the output end of the cylinder 12, and the push arm 13 passes through the placement block 6 and is slidably connected to the placement block 6.

[0036] Three sets of linkage arms 17 are provided on the side wall of the push arm 13 at equal intervals, and the linkage arms 17 are movably connected to the push arm 13. Each linkage arm 17 is provided with a clamping arm 16 at the end away from the push arm 13, and the clamping arm 16 is movably connected to the linkage arm 17.

[0037] Each clamping arm 16 is provided with a pin 15 at one end near the bearing block 14, and the clamping arm 16 is movably connected to the bearing block 14 through the pin 15.

[0038] The brake disc to be tested is placed over the three sets of clamping arms 16. The cylinder 12 is activated, causing the push arm 13 to move. The push arm 13 then rotates the linkage arm 17. Supported by the bearing block 14, the linkage arm 17 rotates the clamping arms 16 around the pin 15, causing the three sets of clamping arms 16 to rotate outwards. The clamping arms 16 clamp and fix the brake disc from the inside. To ensure the brake disc is level, after clamping, a level is placed on the surface of the brake disc to check its levelness. Then, the drive motor 8 is activated, causing the lead screw 10 to rotate. With the lead screw 10 threadedly connected to the threaded sleeve 9, the lead screw 10 moves the threaded sleeve 9 downwards. The threaded sleeve 9, through the connecting plate 11, moves the dial indicator 7 downwards. The dial indicator 7 is moved downwards to contact the surface of the brake disc. Then, the servo motor 2 is turned on, which drives the gear 3 to rotate. Under the mutual meshing of the gear 3 and the gear ring 4, and the sliding cooperation of the bearing ring 18 and the limiting ring 19, the gear 3 drives the gear ring 4 to rotate. The gear ring 4 drives the integrated frame 5, the connecting plate 11 and the dial indicator 7 to rotate, so that the dial indicator 7 moves on the upper surface of the brake disc. If the dial indicator 7 moves to an uneven position, it will generate data fluctuations. This data is sent to the computer through the logic processor and the computer generates a signal to mark whether the brake disc is qualified. This realizes convenient linkage external expansion center clamping and fixing of the brake disc, which facilitates the circumferential inspection of the brake disc and improves the inspection efficiency of the brake disc flatness.

[0039] Working principle: The brake disc to be tested is placed over the three sets of clamping arms 16. The cylinder 12 drives the push arm 13 to move, which in turn drives the linkage arm 17 to rotate. Supported by the bearing block 14, the linkage arm 17 drives the clamping arm 16 to rotate around the pin 15, causing the three sets of clamping arms 16 to rotate outward. The clamping arms 16 clamp and fix the brake disc from the inside. To ensure the brake disc is level, after clamping, a level is placed on the surface of the brake disc to check its levelness. The drive motor 8 drives the lead screw 10 to rotate, which in turn drives the threaded sleeve 9 to move downward. The threaded sleeve 9, through the connection... Plate 11 moves dial indicator 7 downwards so that dial indicator 7 contacts the surface of the brake disc. Servo motor 2 drives gear 3 to rotate. Under the sliding engagement of bearing ring 18 and limit ring 19, gear 3 drives gear ring 4 to rotate. Gear ring 4 drives integrated frame 5, connecting plate 11 and dial indicator 7 to rotate, so that dial indicator 7 moves on the upper surface of the brake disc. If dial indicator 7 moves to an uneven position, it will generate data fluctuation. This data is sent to computer through logic processor and computer generates a signal to mark whether the brake disc is qualified, thereby completing the use of the flatness detection device for brake disc production and processing.
