Description

Technical Field

[0001] This utility model relates to the field of brake disc manufacturing technology, specifically a positioning device for electric vehicle brake discs. Background Technology

[0002] With the rapid expansion of the electric vehicle market, the production quality and efficiency of its various components are receiving increasing attention. As a core component of the electric vehicle braking system, the brake disc directly relates to vehicle safety and the lives of passengers. Therefore, the positioning process is crucial in brake disc production. The positioning accuracy of the brake disc directly impacts subsequent processing, assembly, and other procedures.

[0003] Chinese Patent No. CN219945856U discloses a clamping and positioning device for manufacturing automotive brake discs. It includes a mounting base with several mounting holes, and a housing is fixedly mounted on the mounting base. A handle is provided; rotating the handle drives a bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it causes two adjusting blocks to move relative to each other. During this relative movement, a connecting rod drives several inner fixing plates to move relative to each other, achieving the function of clamping and unlocking the inner walls of brake discs of different sizes. In conjunction with several outer fixing plates, the inner and outer walls of the brake disc are synchronously fixed, ensuring stability during brake disc processing.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, because the device has positioning mechanisms set at both the inner and outer diameters of the brake disc, the part of the brake disc covered by the positioning mechanisms is difficult to process effectively, which greatly reduces the flexibility of the device. Therefore, it is necessary to provide a positioning device for electric vehicle brake discs to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for electric vehicle brake discs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A first gear is fixedly installed on one end of the adjusting screw. A positioning claw is sleeved on the outer wall of the adjusting screw and is slidably connected to the limiting groove. A double-sided annular toothed plate is rotatably installed on the outer side of the lifting plate and meshes with the first gear. A driving mechanism is provided at the bottom of the lifting plate.

[0012] Preferably, the driving mechanism includes a second servo motor, which is fixedly installed on the bottom of the lifting plate. A second gear is fixedly installed on the driving end of the second servo motor, and the second gear meshes with a double-sided annular toothed plate.

[0013] Preferably, a plurality of auxiliary telescopic rods are fixedly installed on the top of the base plate, and the telescopic ends of the auxiliary telescopic rods are fixedly connected to the bottom of the lifting plate.

The clamp can be used to position and fix the outer diameter of the brake disc, while the positioning claw can be used to position and fix the inner diameter. These two positioning methods are independent and can be flexibly used according to processing requirements. In this way, during brake disc processing, effective processing operations can be easily performed on the parts covered by the positioning mechanism. Furthermore, when positioning is not required, the clamp or positioning claw can be removed from the processing area, avoiding interference with the brake disc processing. This significantly improves the flexibility and practicality of the device in practical applications, better adapting to diverse brake disc processing scenarios. Attached Figure Description

[0028] The bottom of the processing table 1 is fixedly installed with several fixing rods 11 on the outside of the through hole 2. The bottom end of the fixing rods 11 is fixedly installed with a base plate 10, and the top of the base plate 10 is provided with an inner diameter positioning mechanism.

[0029] The inner diameter positioning mechanism includes a hydraulic telescopic rod 17, which is fixedly installed on the top of the base plate 10. A lifting plate 13 is fixedly installed on the drive end of the hydraulic telescopic rod 17. Several limiting grooves 14 are evenly and equidistantly opened on the top of the lifting plate 13. An adjusting screw 19 is rotatably installed inside the limiting groove 14. One end of the adjusting screw 19 passes through the lifting plate 13 and extends to the outside of the lifting plate 13. A first gear 16 is fixedly installed on one end of the adjusting screw 19. A positioning claw 12 is sleeved on the outer wall of the adjusting screw 19 and is slidably connected to the limiting groove 14. A double-sided annular toothed plate 15 is rotatably installed on the outer side of the lifting plate 13 and meshes with the first gear 16. A driving mechanism is provided at the bottom of the lifting plate 13, which realizes the automatic positioning and clamping effect of the inner diameter of the brake disc.

[0030] In one embodiment, the driving mechanism includes a second servo motor 20, which is fixedly mounted on the bottom of the lifting plate 13. A second gear 21 is fixedly mounted on the driving end of the second servo motor 20, and the second gear 21 meshes with the double-sided annular toothed plate 15, which can stably drive the double-sided annular toothed plate 15 to rotate.

[0031] In one preferred embodiment, a plurality of auxiliary telescopic rods 18 are fixedly installed on the top of the base plate 10, and the telescopic ends of the auxiliary telescopic rods 18 are fixedly connected to the bottom of the lifting plate 13, thereby improving the stability of the base plate 10 during operation.

[0032] In one embodiment, the outer wall of the bidirectional lead screw 7 is provided with symmetrically distributed left-hand threads and right-hand threads.

The adjusting block 4 is threadedly connected to the bidirectional lead screw 7 through the threaded hole, so that the two adjusting blocks 4 can move relative or oppositely in sync with the rotation of the lead screw, thereby efficiently achieving the clamping or loosening positioning of the outer diameter of the brake disc.

[0033] In one preferred embodiment, the positioning claw 12 has a threaded hole that matches the adjusting screw 19, and the positioning claw 12 is threadedly connected to the adjusting screw 19 through the threaded hole, so that the positioning claw 12 can retract or extend as the adjusting screw 19 rotates, which is convenient for positioning, clamping or releasing the inner ring of the brake disc, and the operation is simple and efficient.

[0034] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a computer or other conventionally known control device. Existing publicly available power connection technologies are not detailed here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, the brake disc is placed on top of the machining table 1, above the through hole 2. When the outer diameter of the brake disc needs to be fixed, the first servo motor 8 is operated, causing its drive end to rotate the bidirectional lead screw 7. Utilizing the thread transmission characteristics of the left-hand and right-hand threads on the bidirectional lead screw 7, and the sliding engagement of the adjusting block 4 within the slide rail 3, the two adjusting blocks 4 are smoothly moved relative to each other or in opposite directions. The movement of the adjusting block 4 drives the connecting arm 5, which in turn moves the clamp 6, causing the two clamps 6 to move relative to each other, thus fixing the outer diameter of the brake disc and precisely clamping and positioning it on top of the machining table 1. At this time, machining operations can be performed on the inner diameter and other parts of the brake disc. When machining the outer diameter of the brake disc is required, the two clamps 6 are controlled to move in opposite directions away from the brake disc. Simultaneously, the hydraulic telescopic rod 17 is activated, its drive end driving the lifting plate 13 to rise and fall, allowing the positioning claw 12 to pass through the through hole 2 and through the inner ring of the brake disc. Then, the second servo motor 20 is operated, its drive end driving the second gear 21 to rotate. Through the meshing transmission between the second gear 21 and the double-sided annular toothed plate 15, the double-sided annular toothed plate 15 rotates. Then, through the meshing of the double-sided annular toothed plate 15 and the first gear 16, the first gear 16 drives the adjusting screw 19 to rotate. Through the threaded transmission between the adjusting screw 19 and the positioning claw 12, and the sliding of the positioning claw 12 within the limiting groove 14, multiple positioning claws 12 are simultaneously retracted or extended. Multiple positioning claws 12 are simultaneously extended and pressed against the inner ring of the brake disc, achieving positioning and clamping from the inner ring position of the brake disc. At this time, the outer diameter of the brake disc can be machined.
