Description

Technical Field

[0001] This utility model relates to the technical field of aperture detection devices, specifically a device for detecting the aperture of a brake disc stamping die that is easy to position. Background Technology

[0002] In the production process of brake disc stamping dies, it is crucial to inspect the die bore diameter. As a key component of the automotive braking system, the quality of the brake disc directly affects driving safety. The accuracy of the die bore diameter determines the dimensional accuracy of the corresponding holes on the brake disc. If the bore diameter does not meet the design standards, it will lead to difficulties in assembling the brake disc with other components, affecting the overall performance of the braking system, and may even cause serious safety hazards such as brake failure. Therefore, strictly inspecting the die bore diameter during the production process is an indispensable and important measure to ensure the quality of brake discs and guarantee driving safety.

[0003] Currently, the positioning methods for inspecting the bore diameters of multiple brake disc stamping dies are complex and cumbersome, requiring inspectors to spend a significant amount of time on preparation and adjustments. Positioning accuracy is also difficult to guarantee; large positional deviations occur when positioning different dies or when positioning the same die multiple times, affecting the consistency and accuracy of the test results. Furthermore, existing positioning devices have poor adaptability; when faced with brake disc stamping dies of different specifications and shapes, it often requires replacing numerous parts or making complex modifications, failing to quickly and flexibly meet diverse testing needs and severely hindering the efficiency and quality improvement of testing work. Therefore, we propose a brake disc stamping die bore diameter inspection device that facilitates positioning. Utility Model Content

[0004] The purpose of this invention is to provide a brake disc stamping die bore diameter detection device that facilitates positioning, thereby solving the problems mentioned in the background art. Currently, when detecting the bore diameters of multiple brake disc stamping dies, the positioning method is complex and cumbersome, requiring inspectors to spend a lot of time on preliminary preparation and adjustment. The positioning accuracy is also difficult to guarantee. When positioning different dies or the same die multiple times, the positional deviation is large, which affects the consistency and accuracy of the test results. Moreover, the existing positioning devices have poor adaptability. When facing brake disc stamping dies of different specifications and shapes, it is often necessary to replace a large number of parts or carry out complex modifications, which cannot quickly and flexibly meet diverse testing needs, seriously restricting the efficiency and quality improvement of testing work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brake disc stamping die bore diameter detection device for easy positioning, comprising a base, a turntable at the upper end of the base, a rotating column fixedly connected to the center of the bottom of the turntable, a reduction motor fixedly installed on one side of the bottom of the base, a placement groove on the top of the turntable, a positioning plate arranged on one side of the placement groove, rubber plates fixedly installed on the opposite side of the positioning plate and the placement groove, and connecting rods fixedly connected to the top and bottom of one side of the positioning plate, with one end of each connecting rod penetrating to... Outside the turntable, a connecting plate is fixedly connected to one side of the two connecting rods. A rectangular cavity is opened in the center of one side of the placement slot. A spring is fixedly connected to one side of the rectangular cavity. A connecting block is fixedly connected to one end of the spring. A vertical plate is provided on one side of the base. A pressure plate is provided on one side of the vertical plate corresponding to one end of the connecting plate. A first electric cylinder is fixedly installed at the bottom of one side of the vertical plate. A second electric cylinder is fixedly installed at the center of the top of the vertical plate. A lifting plate is provided at the top of one side of the vertical plate. An aperture detection probe is provided at the lower end of the lifting plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This easy-to-position brake disc stamping die hole diameter detection device, through the design of placement slots, positioning plates, rubber plates, connecting rods, connecting plates, springs, connecting blocks, a first electric cylinder, and pressure plates, allows multiple dies to be tested to be placed in their respective placement slots on a turntable during brake disc stamping die hole diameter detection. As the turntable rotates, when each placement slot rotates to the side of the pressure plate, the first electric cylinder activates, causing the pressure plate to move towards the connecting plate. After the pressure plate contacts the connecting plate, the connecting rod drives the positioning plate to move towards the die side within the placement slot. The positioning plate cooperates with the inner wall of the placement slot to accurately position the die. The rubber plate increases the friction with the die, ensuring stable positioning, and also acts as a buffer to prevent damage to the die during positioning. During positioning, the spring is stretched. After the die hole diameter detection is completed, the device is ready to be tested. The first electric cylinder drives the pressure plate to reset, at which point the spring recovers its deformation and pulls the positioning plate back to its initial position via the connecting block, causing the positioning mechanism to open automatically. Subsequently, the turntable continues to rotate, rotating the mold in the next placement slot to the detection position, repeating the above positioning and detection process. This design, on the one hand, enables quick and accurate positioning of the mold during the detection process, greatly improving the accuracy and efficiency of the detection and avoiding detection errors caused by inaccurate mold positioning; on the other hand, the positioning mechanism can open automatically after the detection is completed, eliminating the need for manual operation, making it convenient for operators to remove the mold from the placement slot, further improving the convenience of operation and overall work efficiency. Compared with the existing technology, which suffers from difficulties in mold positioning, low detection efficiency, and inconvenience in removing and placing molds, this device has significant advantages.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5This utility model provides a technical solution: a brake disc stamping die hole diameter detection device for easy positioning, including a base 1, a turntable 2 at the upper end of the base 1, a rotating column 3 fixedly connected to the center of the bottom of the turntable 2, a reduction motor 4 fixedly installed on one side of the bottom of the base 1, a placement groove 5 on the top of the turntable 2, a positioning plate 6 arranged on one side of the placement groove 5, rubber plates 7 fixedly installed on the opposite side of the positioning plate 6 and the placement groove 5, and connecting rods 8 fixedly connected to the top and bottom of one side of the positioning plate 6, with one end of each connecting rod 8 extending through to the outside of the turntable 2. A connecting plate 9 is fixedly connected to one side of the base 1. A rectangular cavity 10 is opened in the center of one side of the placement groove 5. A spring 11 is fixedly connected to one side of the rectangular cavity 10. A connecting block 12 is fixedly connected to one end of the spring 11. A vertical plate 15 is provided on one side of the base 1. A pressure plate 17 is provided on one side of the vertical plate 15 corresponding to one end of the connecting plate 9. A first electric cylinder 16 is fixedly installed at the bottom of one side of the vertical plate 15. A second electric cylinder 18 is fixedly installed at the center of the top of the vertical plate 15. A lifting plate 19 is provided at the top of one side of the vertical plate 15. An aperture detection probe 21 is provided at the lower end of the lifting plate 19.

[0016] The bottom of the rotating column 3 extends into the interior of the base 1 and is movably connected to a bearing fixedly installed on one side of the bottom of the base 1. A driven gear is fixedly installed on the surface of the rotating column 3 near the center. A driving gear is meshed with one side of the driven gear. A reduction motor 4 is fixedly connected to a drive shaft through its top output end. The upper end of the drive shaft is fixedly connected to the center of the bottom of the driving gear. The reduction motor 4 drives the drive shaft to rotate, which in turn drives the driving gear to rotate, thereby driving the driven gear meshing with the driving gear to rotate. The driven gear drives the rotating column 3 to rotate, providing power for the rotation of the turntable 2. This enables the molds in the multiple placement slots 5 on the turntable 2 to rotate sequentially, facilitating continuous hole diameter detection of different molds and improving the automation and efficiency of the detection.

[0017] Several ball bearing sets are rolled on the upper end of the base 1. The bottom of the turntable 2 has an annular groove corresponding to the top of each ball bearing set. The upper end of the ball bearing set passes through the interior of the annular groove and contacts the inner wall of the annular groove, which transforms the sliding friction between the turntable 2 and the base 1 into rolling friction. This greatly reduces the friction force when the turntable 2 rotates, making the turntable 2 rotate more smoothly and stably, reducing energy consumption and wear during the rotation process. It also helps to improve the rotation accuracy of the turntable 2, thereby ensuring the accuracy of mold positioning and inspection.

[0018] The number of placement slots 5 is set in a ring array. The ball bearing assembly cooperates with the ring slots. The multiple placement slots 5 are arranged in a ring array on the turntable 2, which can simultaneously place multiple brake disc stamping dies to be tested. When the turntable 2 rotates, it can sequentially rotate the dies in each placement slot 5 to the test position, realize the continuous testing of multiple dies, make full use of the testing equipment time, greatly improve the efficiency of the testing work, and reduce the idle time of the equipment.

[0019] One side of the connecting block 12 extends through to the outside of the rectangular cavity 10 and is fixedly connected to the center of one side of the positioning plate 6. A sliding groove 13 is provided on one side of the top and bottom of the rectangular cavity 10. A slider 14 is fixedly connected to one side of the top and bottom of the connecting block 12. The two sliders 14 are slidably connected to the inner walls of the two sliding grooves 13 respectively. By sliding the sliders 14 in the sliding grooves 13, the positioning plate 6 can be moved smoothly and accurately under the action of the spring 11, so that the positioning plate 6 forms a stable and resettable clamping force on the mold, ensuring the accuracy of mold positioning. At the same time, the reset function of the spring 11 allows the positioning plate 6 to open automatically after detection, which is convenient for mold loading and unloading.

[0020] The No. 1 electric cylinder 16 is fixedly connected to the No. 1 piston rod through its output end on one side. The end of the No. 1 piston rod away from the No. 1 electric cylinder 16 is fixedly connected to the center of one side of the pressure plate 17. The No. 1 electric cylinder 16 is controlled to push the pressure plate 17 to move horizontally.

[0021] A base plate is fixedly installed at the bottom of the base 1 and the vertical plate 15. A vertical cavity is opened at the top of the vertical plate 15. One end of the lifting plate 19 passes through the interior of the vertical cavity and is fixedly connected to a guide block. A guide groove is opened on one side of the vertical cavity. One end of the guide block extends into the interior of the guide groove and slides in connection with the inner wall of the guide groove. A second electric cylinder 18 is fixedly connected to a second piston rod through its bottom output end. The lower end of the second piston rod passes through the interior of the vertical cavity and is fixedly connected to one side of the top of the lifting plate 19. A guide rail is fixedly installed on one side of the bottom of the vertical plate 15. A linear motor 20 is movably installed at the lower end of the guide rail. The upper end of the aperture detection probe 21 is fixedly connected to the bottom of the linear motor 20. The second electric cylinder 18 drives the lifting plate 19 to move up and down in the vertical cavity through the second piston rod. The cooperation between the guide block and the guide groove ensures the smooth movement of the lifting plate 19. The linear motor 20 moves horizontally on the guide rail, driving the aperture detection probe 21 to flexibly adjust its position in the horizontal direction. This allows for precise adjustment of the detection position according to the actual aperture of the mold, improving the flexibility and accuracy of the detection and enabling it to meet the aperture detection needs of molds of different specifications.

[0022] When the easy-to-position brake disc stamping die bore diameter detection device is working, multiple brake disc stamping dies to be tested are first placed sequentially into the placement slots 5 arranged in a ring on the turntable 2. At this time, the dies are in a natural placement state after being placed in the placement slots 5. Under the initial tension of the spring 11, the positioning plate 6 is on the side relatively away from the die, and will not clamp the die. Then, the reduction motor 4 is started, and its drive shaft drives the drive gear to rotate. The drive gear drives the driven gear meshing with it to rotate. The driven gear drives the rotating column 3 to rotate in the base 1. With the cooperation of the ball bearing assembly at the upper end of the base 1 and the ring groove at the bottom of the turntable 2, the turntable 2 rotates smoothly, rotating the dies in each placement slot 5 to the detection position in sequence. When the placement slot 5 rotates to the side of the pressure plate 17, the first electric cylinder 16 is started, pushing the pressure plate 17 towards the connecting plate 9 through the first piston rod. After the pressure plate 17 contacts the connecting plate 9, the connecting rod 8 drives the positioning plate 6 towards the die in the placement slot 5. The positioning plate 6 moves to one side, and the rubber plate 7 on the inner wall of the placement groove 5 cooperates to accurately position the mold. The rubber plate 7 increases the friction between the mold and the positioning plate 7, ensuring stable positioning and providing a buffering effect. Then, the second electric cylinder 18 drives the lifting plate 19 to move up and down in the vertical cavity of the vertical plate 15 through the second piston rod. The guide block and the guide groove cooperate to ensure that the lifting plate 19 moves smoothly and adjusts the vertical position of the aperture detection probe 21. At the same time, the linear motor 20 moves horizontally on the guide rail, driving the aperture detection probe 21 to flexibly adjust its position in the horizontal direction, so that the aperture detection probe 21 is accurately aligned with the mold aperture for detection. After the detection is completed, the first electric cylinder 16 drives the pressure plate 17 to reset. At this time, the spring 11 returns to its deformation and pulls the positioning plate 6 back to the initial position through the connecting block 12. The positioning mechanism automatically opens, and the turntable 2 continues to rotate, rotating the next mold in the placement groove 5 to the detection position. The above positioning and detection process is repeated until all molds are detected.

[0023] In summary, this easy-to-position brake disc stamping die hole diameter detection device, through the design of placement slots 5, positioning plates 6, rubber plates 7, connecting rods 8, connecting plates 9, springs 11, connecting blocks 12, electric cylinder 16, and pressure plates 17, allows multiple dies to be tested to be placed in the placement slots 5 on the turntable 2 during brake disc stamping die hole diameter detection. As the turntable 2 rotates, when each placement slot 5 rotates to the side of the pressure plate 17, the electric cylinder 16 starts, driving the pressure plate 17 to move towards the connecting plate 9. After the pressure plate 17 contacts the connecting plate 9, the connecting rod 8 drives the positioning plate 6 to move towards the die side within the placement slot 5. The positioning plate 6 cooperates with the inner wall of the placement slot 5 to accurately position the die. The rubber plate 7 increases the friction with the die, ensuring stable positioning, and also acts as a buffer to prevent damage to the die during positioning. During positioning, the spring 11 is pulled... Once the mold aperture detection is complete, the first electric cylinder 16 drives the pressure plate 17 to reset. At this time, the spring 11 recovers its deformation and pulls the positioning plate 6 back to its initial position through the connecting block 12, causing the positioning mechanism to open automatically. Subsequently, the turntable 2 continues to rotate, rotating the next mold in the placement slot 5 to the detection position, repeating the above positioning and detection process. This design method, on the one hand, can quickly and accurately position the mold during the detection process, greatly improving the accuracy and efficiency of the detection and avoiding detection errors caused by inaccurate mold positioning; on the other hand, the positioning mechanism can open automatically after the detection is completed, without manual operation, making it convenient for operators to remove the mold from the placement slot 5, further improving the convenience of operation and overall work efficiency. Compared with the existing technology, which suffers from difficulties in mold positioning, low detection efficiency, and inconvenience in picking up and placing molds, this device has significant advantages.
