Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a drilling device for automotive brake calipers that can prevent shaking. Background Technology

[0002] The brake caliper is an indispensable key component in the automotive braking system. It is mainly responsible for transmitting the hydraulic oil pressure generated by the master cylinder to the brake pads, thereby achieving the purpose of braking.

[0003] Drilling is a crucial step in the production of brake calipers. However, existing brake caliper drilling equipment often struggles to accommodate brake calipers of different shapes, resulting in poor fixation and causing the caliper to wobble during drilling. This not only affects the accuracy and quality of the drilling but also damages the drill bit, increasing production costs and processing time. Therefore, it is necessary to redesign a brake caliper drilling equipment that can prevent wobble. Utility Model Content

[0022] This utility model provides a technical solution for a drilling and machining device for automotive brake calipers that can prevent shaking:

[0023] Please see Figs. 1-4 A drilling and machining device for automotive brake calipers that prevents shaking includes a base 1, a support seat 2 fixedly mounted on the upper surface of the base 1, a bidirectional screw 3 rotatably mounted on the outer wall of the base 1 via a moving groove, a motor 4 fixedly mounted on the outer wall of the base 1 and connected to the bidirectional screw 3, two moving blocks 6 rotatably mounted on the outer wall of the bidirectional screw 3 via a limiting mechanism, assembly plates 8 fixedly connected to the outer walls of the two moving blocks 6 via a connecting mechanism, and two support shafts 9 fixedly mounted on the upper surfaces of the two assembly plates 8. Clamping plates 10 are slidably installed on the outer walls. Each clamping plate 10 has a sliding opening on its upper surface that mates with the support shaft 9. Electric push rods 13 are fixedly installed on the upper surfaces of the two assembly plates 8 through a support mechanism. First connecting frames 14 are fixedly installed on the telescopic ends of the two electric push rods 13. Two connecting plates 15 are rotatably installed inside the two first connecting frames 14. A second connecting frame 16 is rotatably installed at the end of each connecting plate 15. Each second connecting frame 16 is fixedly connected to the outer wall of the corresponding clamping plate 10.

[0024] Furthermore, the limiting mechanism includes a limiting rod 5 fixedly installed inside the moving groove. The limiting rod 5 slides through the two moving blocks 6, and the limiting rod 5 can restrict the two moving blocks 6 so that the two moving blocks 6 can only move axially along the outer wall of the bidirectional screw 3.

[0025] Furthermore, the connecting mechanism includes a connecting plate 7 fixedly installed on the outer wall of the movable block 6, with the end of the connecting plate 7 fixedly connected to the outer wall of the assembly plate 8.

[0026] Furthermore, the support mechanism includes a support plate 12 fixedly installed on the upper end face of the assembly plate 8, and an electric actuator 13 fixedly installed on the inner wall of the support plate 12.

[0027] Furthermore, each clamping plate 10 has an anti-slip toothed plate 11 fixedly installed on its inner wall. Each anti-slip toothed plate 11 is made of vulcanized rubber. Vulcanized rubber refers to rubber that has been vulcanized. It has properties such as not sticking and not being easy to break. It also has high elasticity, heat resistance, tensile strength and insolubility in organic solvents.

[0028] In practical use, the working principle of this utility model is as follows:

[0029] The workpiece can be placed on the upper surface of the support base 2, and then the motor 4 is started. After the motor 4 is powered on, its output shaft drives the bidirectional screw 3 connected to it to rotate in the moving groove. Since the limiting rod 5 passes through the moving block 6 and the limiting rod 5 is fixed in the moving groove, the moving block 6 cannot rotate with the bidirectional screw 3, but can only move in a straight line along the thread direction of the bidirectional screw 3. As the bidirectional screw 3 continues to rotate, the two moving blocks 6 will move relative to each other or away from each other according to the thread direction of the bidirectional screw 3. The connecting plate 7 drives the assembly plate 8 to move synchronously, thereby adjusting the distance between the two assembly plates 8 to adapt to the placement requirements of workpieces of different sizes.

[0030] Once the assembly plate 8 is adjusted to the appropriate position, the electric actuator 13 is activated. The telescopic end of the electric actuator 13 begins to move, pushing the first connecting frame 14 connected to it to move. During the movement of the first connecting frame 14, it causes the internally rotatably mounted connecting plate 15 to change its angle. Since the other end of the connecting plate 15 is rotatably mounted on the second connecting frame 16, and the second connecting frame 16 is fixedly connected to the outer wall of the clamping plate 10, the change in the angle of the connecting plate 15 will pull the second connecting frame 16, causing the clamping plate 10 to slide along the sliding opening on the support shaft 9. The two clamping plates 10 gradually approach the workpiece. The vulcanized rubber anti-slip toothed plate 11 on the inner wall of the clamping plate 10 is tightly attached to the surface of the workpiece. The vulcanized rubber anti-slip toothed plate 11 has good flexibility and large friction, which can increase the contact area with the workpiece, disperse the clamping force, and effectively prevent the workpiece from shaking due to uneven force during drilling. At this time, the workpiece is stably clamped, and the matching drilling equipment can be used to drill the workpiece. Throughout the process, the device ensures the stability of the workpiece during drilling and improves the accuracy and quality of drilling by virtue of its stable clamping structure and reasonable power transmission design.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
