Detailed Implementation

[0021] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0022] like Figure 1 and Figure 2 As shown, a special device for processing a disc brake bracket includes a first reinforcing rib and a second reinforcing rib connected at both ends. A mounting groove is provided through the middle of the first and second reinforcing ribs. Specifically, the special device for processing a disc brake bracket includes a tooling base 3. Taking the horizontally positioned state of the tooling base 3 before flipping as the directional reference, support frames 1 are provided on the left and right sides of the tooling base 3. A motor 13 is externally connected to the right support frame 1. The tooling base 3 rotates around a shaft 14 parallel to the left and right directions on both sides of the support frame 1. A useful... The hydraulic brake locks the rotation angle of the fixture base 3. The fixture base 3 is equipped with a reinforcing rib support assembly for positioning the middle of the workpiece, a lower support assembly for supporting the bottom of the workpiece, a clamping device 5 for pressing the workpiece, and a flipping support assembly for supporting the workpiece after flipping. The reinforcing rib support assembly is located in the middle of the fixture base 3, and the lower support assembly is located on the outside of the reinforcing rib support assembly. The flipping support assembly includes a side positioning member 12 for abutting against the side wall of the workpiece and an inner positioning member 11 for extending into the mounting groove. It allows for rapid switching of the workpiece processing angle, offering strong versatility and practicality. The support frame 1 has a built-in hydraulic brake, which improves the stability of angle adjustment through hydraulic locking, reduces the risk of vibration and deviation during processing, saves fixture space, and ensures that the fixture stops precisely at the required angle and position, guaranteeing the required angle for the processed workpiece.

[0023] Specifically, the support frame 1 has four positioning holes at its bottom, allowing for quick connection and fixation to the machine tool, facilitating rapid tooling changes. The tooling base 3 is rotatably connected to the support frame 1 via a rotating support 2 and a tooling rotating block 4. The rotating support 2 is rotatably connected to the support frame 1 and is hydraulically braked to the rotating support 2. The tooling rotating block 4 is connected to the rotating support 2, and the tooling base 3 is connected to the tooling rotating block 4. Two side positioning elements 12 and two inner positioning elements 11 are each provided, symmetrically arranged on both sides, working together to form a composite positioning reference, ensuring balanced bidirectional force during machining.

[0024] Furthermore, the reinforcing rib support assembly includes a first reinforcing rib support seat 6 and a second reinforcing rib support seat 7. The first reinforcing rib support seat 6 and the second reinforcing rib support seat 7 are symmetrically arranged from left to right to form a stable positioning, effectively constraining the radial displacement of the workpiece during processing and improving positioning accuracy.

[0025] Furthermore, the first reinforcing rib support 6 is arched, which adapts to the arched structure in the middle of the first and second reinforcing ribs and enhances the compressive strength of the support. Both ends of the support are rotatably connected with ball bearings, so that the workpiece can achieve a small amount of sliding when the angle is adjusted, which ensures the positioning reliability and avoids surface scratches.

[0026] Furthermore, the upper end of the second reinforcing rib support 7 is fixedly connected to a tapered support, which can automatically compensate for minor deviations and improve the positional stability during the processing.

[0027] Furthermore, the lower support assembly includes a first lower support block 8, a second lower support block 9, and a third lower support block 10. The first lower support block 8, the second lower support block 9, and the third lower support block 10 are arranged in an L-shape and a triangle to form multi-directional support, which can achieve full circumferential bearing for the irregular structure at the bottom of the workpiece and prevent deformation caused by local stress concentration.

[0028] Furthermore, the upper ends of the first lower support block 8, the second lower support block 9, and the third lower support block 10 are conical top structures cut parallel to the front side of the axis, and the tops are flattened.

[0029] Furthermore, the clamping device 5 includes a rotary drive unit and a rotating arm. The rotary drive unit is mounted and fixed on the tooling base 3, and the rotary drive unit is driven and connected to the rotating arm. The rotation axis of the rotating arm is set perpendicular to the rotation axis of the tooling base 3.

[0030] Furthermore, the rotating arm includes a mounting part, a connecting part, and a clamping part in sequence. The clamping part is raised relative to the mounting part through the connecting part to form a clearance space.

[0031] In summary, the above solutions enable rapid tooling changeover, accurate positioning, quick switching of product processing angles, strong versatility, high practicality, high efficiency, and guaranteed quality, thus providing a good match for automated production.
