Description

Technical Field

[0001] This utility model relates to the field of disc brake caliper processing, and more specifically, to a processing device for disc brake calipers. Background Technology

[0002] Disc brakes consist of a brake disc connected to the wheel and brake calipers on the edge of the disc. When braking, high-pressure brake fluid pushes the brake pads to clamp the brake disc, thus producing a braking effect. Currently, all mechanical disc brake locks on the market are independent split structures with different models and sizes. After the vehicle is locked, the lock body is suspended between the disc brake caliper and the frame. During the manufacturing process of disc brake calipers, a drilling device is needed to perform drilling operations. The disc brake caliper needs to be fixed during drilling to prevent it from shifting during drilling.

[0003] A search revealed that Chinese patent application number 202320801701.X discloses a "disc brake caliper processing device, including a base, side plates fixedly connected to both sides of the top of the base, an electric slide rail fixedly connected to the top of the side plates, a cylinder fixedly connected to the bottom of the electric slide rail, a drilling mechanism fixedly connected to the bottom of the cylinder, an electric push rod fixedly connected to the top of the inner cavity of the base, a housing fixedly connected to the bottom of the electric push rod, a motor fixedly connected to the bottom of the inner cavity of the housing, and a screw fixedly connected to the output end of the motor. This invention, through the coordinated use of the base, side plates, electric slide rail, cylinder, drilling mechanism, electric push rod, housing, motor, screw, threaded sleeve, clamping plate, and pressure plate, solves the problem of poor fixing effect and inability to effectively limit the workpiece in existing disc brake caliper processing drilling devices, leading to easy shaking of the workpiece during processing, increasing the number of defective products, and thus failing to meet practical needs." However, it still has the following drawbacks:

[0004] (1) The calipers come in various sizes and the fixing devices cannot be flexibly adapted, resulting in unstable clamping or damage to the workpiece. During the processing, the calipers are prone to displacement, resulting in deviation of the drilling position, affecting the quality of the finished product and causing unstable clamping or damage to the workpiece.

[0005] (2) Traditional caliper processing devices are difficult to meet the requirements of multi-angle drilling, and the workpiece position needs to be adjusted frequently, resulting in low efficiency. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0037] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a processing device for disc brake calipers, including a base 10, a drive linear guide 110 driven by a linear motor and mounted on the outer wall of the base 10, and a swing cylinder embedded in the center of the base 10, and further including:

[0040] The swing disk 20 is fixedly installed on the swing end of the swing cylinder, and the swing disk 20 is rotatably connected to the base 10.

[0041] Positioning rod 30 is symmetrically installed on the top of swing disk 20, and a connecting plate 310 is fixedly connected to the end of positioning rod 30 away from swing disk 20;

[0042] The upper positioning plate 40 is evenly arranged on the outer side wall of the positioning rod 30. An avoidance groove is provided at the center of the upper positioning plate 40. The outer side wall of the upper positioning plate 40 is integrally formed with evenly distributed upper positioning frames 410. The top of the upper positioning plate 40 is provided with evenly distributed auxiliary positioning components 420 for constraining the caliper.

[0043] The drive screw 50 is installed on the side of the connecting plate 310 near the positioning rod 30. The drive screw 50 is driven by a forward and reverse motor. The end of the drive screw 50 away from the connecting plate 310 passes through the clearance groove and is rotatably connected to the swing disk 20.

[0044] The lower positioning plate 60 is threaded to the outer wall of the drive screw 50 and is positioned below the upper positioning plate 40. The outer wall of the lower positioning plate 60 is integrally formed with evenly distributed lower positioning frames 610.

[0045] Robotic arm 70 is mounted on the moving end of drive linear guide 110;

[0046] Drill bit 80 is installed at the output end of robotic arm 70;

[0047] The control system, based on a preset machining angle command, activates the swing cylinder, driving the swing disk 20 to rotate around the center of the base 10, thus moving the caliper to the target machining angle, such as 0°, 90°, or 180°. The hollow collection groove 210 rotates synchronously with the swing disk 20, maintaining a continuous chip guide path. A linear motor drives the robotic arm 70 to move horizontally along the drive linear guide rail 110, adjusting the X / Y axis position of the drill bit 80 to match the coordinates of the hole to be drilled by the caliper. The multi-degree-of-freedom joints at the end of the robotic arm 70 further fine-tune the attitude of the drill bit 80, ensuring... With a vertical cut, the drill bit 80 rotates and feeds at high speed under the drive of the robotic arm 70 to complete the drilling operation at the designated position of the caliper. The closed-loop control of the linear motor ensures that the drilling depth and position accuracy error is ≤0.1mm. After the single hole is processed, the swing cylinder drives the caliper to rotate to the next processing angle, and the robotic arm moves synchronously to the corresponding coordinate to realize multi-face continuous drilling. After the processing is completed, the drive screw 50 reverses, the lower positioning plate 60 descends and resets, the pressure plate 423 of the auxiliary positioning component 420 is loosened, and the operator takes out the finished caliper.

[0048] like Figure 1 and Figure 2 As shown, the top of the swing disk 20 is provided with a hollow collection groove 210 for collecting drilling debris.

[0049] like Figure 3and Figure 4 As shown, the lower positioning plate 60 includes a plate body 620 placed below the upper positioning plate 40. A slot is provided in the middle of the plate body 620. A ball cover 630 is fixedly connected to the bottom of the plate body 620. The inner cavity of the ball cover 630 communicates with the slot. A threaded groove 640 is provided at the center of the ball cover 630, which is threaded to engage with the drive screw 50. When the drive screw 50 driven by the forward and reverse motor is started, the lower positioning plate 60 is driven to rise along the screw, so that the lower positioning frame 610 contacts the bottom of the caliper, forming initial support. As the drive screw 50 continues to rotate, the lower positioning plate 60 moves down through the threaded groove 640, and supports and positions the caliper body with the upper positioning frame 410 on the upper positioning plate 40.

[0050] like Figure 3 and Figure 4 As shown, the bottom outer wall of the spherical cover 630 is provided with a drain valve 650 communicating with the inner cavity, and the outer wall of the spherical cover 630 is provided with an observation window. The inner wall of the spherical cover 630 is fixedly connected with a protective shell 660 communicating with the threaded groove 640. The protective shell 660 avoids the drive screw 50, isolates drilling debris, and protects the drive screw thread from contamination. The metal debris generated by drilling falls into the inner cavity of the spherical cover 630 through the hollow collection groove 210 of the swing disk 20. The observation window displays the amount of debris accumulation in real time. The operator opens the drain valve 650 periodically to collect and discharge the debris to an external collection container.

[0051] like Figure 3 and Figure 4 As shown, the auxiliary positioning component 420 includes an inverted L-shaped clamping plate 421 fixedly installed on the top of the upper positioning plate 40, with the horizontal section of the inverted L-shaped clamping plate 421 positioned above the upper positioning frame 410.

[0052] like Figure 3 and Figure 4 As shown, a screw 422 is threaded to the horizontal end of the inverted L-shaped clamping plate 421. The screw 422 passes through one end of the horizontal section of the inverted L-shaped clamping plate 421 and is rotatably connected to a pressure plate 423. A rubber layer is provided at the end of the pressure plate 423 away from the screw 422. The operator places the disc brake caliper to be processed in the upper positioning frame 410 area of ​​the upper positioning plate 40 and abuts the caliper against the horizontal section of the inverted L-shaped clamping plate 421. The operator rotates the screw 422 of the auxiliary positioning assembly 420, driving the pressure plate 423 to press down onto the caliper surface. The rubber layer provides flexible contact to prevent scratches. This ensures that the caliper body initially fits the contour of the upper positioning frame 410. The horizontal section of the inverted L-shaped clamping plate 421 covers the edge of the caliper, forming multi-point constraints to resist displacement caused by processing vibrations.

[0053] Specifically, when using the processing device for disc brake calipers: the operator places the disc brake caliper to be processed in the upper positioning frame 410 area of ​​the upper positioning plate 40, and abuts the caliper against the horizontal section of the inverted L-shaped clamping plate 421. The operator rotates the screw 422 of the auxiliary positioning component 420, driving the pressure plate 423 to press down onto the caliper surface. The rubber layer provides flexible contact to prevent scratches. This ensures that the caliper body initially fits the contour of the upper positioning frame 410, and the horizontal section of the inverted L-shaped clamping plate 421 covers the edge of the caliper, forming multi-point constraints to resist displacement caused by processing vibrations.

[0054] Start the drive screw 50 driven by the forward and reverse motor, which drives the lower positioning plate 60 to rise along the screw, so that the lower positioning frame 610 contacts the bottom of the caliper to form initial support. The drive screw 50 continues to rotate, and the lower positioning plate 60 moves down through the threaded groove 640 to support and position the caliper body with the upper positioning frame 410 on the upper positioning plate 40.

[0055] According to the preset machining angle command, the control system starts the swing cylinder, drives the swing disk 20 to rotate around the center of the base 10, and drives the caliper to the target machining angle, such as 0°, 90°, 180°, etc. The hollow collection groove 210 rotates synchronously with the swing disk 20 to keep the chip guide path continuous. The linear motor drives the robotic arm 70 to move horizontally along the drive linear guide rail 110, adjusts the X / Y axis position of the drill bit 80, matches the coordinates of the caliper to be drilled, and the multi-degree-of-freedom joint at the end of the robotic arm 70 further fine-tunes the attitude of the drill bit 80 to ensure vertical cutting.

[0056] The drill bit 80 rotates and feeds at high speed under the drive of the robotic arm 70 to complete the drilling operation at the designated position of the caliper. The closed-loop control of the linear motor ensures that the drilling depth and position accuracy error is ≤0.1mm. After the single hole is processed, the swing cylinder drives the caliper to rotate to the next processing angle, and the robotic arm moves synchronously to the corresponding coordinate to realize multi-face continuous drilling. After the processing is completed, the drive screw 50 reverses, the lower positioning plate 60 descends and resets, the pressure plate 423 of the auxiliary positioning component 420 is loosened, and the operator takes out the finished caliper.

[0057] All technical features in this embodiment can be freely combined according to actual needs.

[0058] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
