However, the shape and structure of the above-mentioned brake caliper blank is relatively complex. When clamped by a standard fixture such as a bench vise, the tool needs to be aligned before each processing to position the product, which leads to low production efficiency and cannot guarantee high precision.

[0008] Through the above technical means, the arc support is used to support the side end of the blank body, so that the blank body is subjected to consistent force up and down when clamping, thereby increasing processing stability.

[0009] Preferably, a space-avoiding groove is formed through the forming block, and the space-avoiding groove is arranged at the upper end of the through hole of the blank body.

[0010] Through the above technical means, the connection hole and the through hole can be processed together without disassembly through the air avoidance groove, so that the positioning reference is consistent and the processing accuracy of the product is increased.

[0024] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0025] A brake caliper rapid positioning processing table includes a machine table, a forming frame 2 is provided on the machine table, a forming block 3 is provided on the upper end of the forming frame 2, a clamping groove 4 is provided in the middle of the forming block 3 to cooperate with the L-shaped plate 94, and a material-repelling cylinder 5 is also provided on the back of the forming frame 2. The material-repelling cylinder 5 is fixed to the forming frame 2 by screws. The output end of the material-repelling cylinder 5 passes through the forming frame 2 and is provided with a retaining block 6. The end of the retaining block 6 is also provided with a positioning head 7, and a guide slope 8 is provided on the positioning head 7. When the positioning head 7 is pushed into the through groove 95, the through groove 95 is pressed against the positioning head 7. The guide bevel 8 is used for guidance to prevent jamming. The material-receiving cylinder 5 drives the positioning head 7 to be stuck in the through groove 95 and makes the retaining block 6 press against the L-shaped plate 94, so that the L-shaped plate 94 is pressed tightly in the clamping groove 4, thereby completing the fixation. An arc retaining platform 9 is also provided on the machine platform. The arc retaining platform 9 is used to press against the bottom of the blank body 90. When the material-receiving cylinder 5 pushes the retaining block 6 to press against the blank body 90, the upper and lower ends of the blank body 90 are pressed tightly at the same time, so that the upper and lower forces of the blank body 90 are consistent when clamping, thereby increasing the processing stability.

[0026] The machine is set in the machining center, which is equipped with a three-axis drive assembly and a spindle box. The three-axis drive assembly is used to drive the spindle box to move in the X, Y, and Z axis directions. The spindle box is used to install the machining tool and drive it to rotate, thereby completing the processing of the blank body 90.

[0027] The forming block 3 is also provided with an air avoidance groove 10, which is arranged at the upper end of the through hole 93 of the blank body 90. The upper end of the forming block 3 is also provided with a second material-repelling cylinder 11, and the upper end of the forming block 3 is provided with a through hole. The output shaft of the second material-repelling cylinder 11 is arranged in the through hole and is used to press the blank body 90. By providing the air avoidance groove 10, the through hole 93 in the middle of the blank body 90 can be processed without disassembling the blank body 90, the positioning reference is kept consistent, and the processing accuracy of the product is increased. The blank body 90 is pressed downward by the second material-repelling cylinder 11, thereby increasing the Z-axis positioning accuracy of the blank body 90. At the same time, the height of the through groove 95 and the bottom thickness of the L-shaped plate 94 can have a large deviation, which facilitates the installation of the L-shaped plate 94 and makes it easier for the blank body 90 to be placed in the clamping groove 4.

[0028] The machine is also provided with a linear slide 12, and a servo motor 13 is provided on the slide seat of the linear slide 12. A drill bit 14 is fixedly provided at the output end of the servo motor 13. The linear slide 12 drives the servo motor 13 to move and process the hydraulic hole. A guide column 15 is also provided on the machine, and a guide hole 16 is provided in the middle of the guide column 15. A material-repelling cylinder 3 18 is also provided at the bottom of the machine. A positioning rod is provided at the output end of the material-repelling cylinder 3 18. The positioning rod slides with the guide hole 16, and a supporting ring 17 is fixed on the positioning rod. When the connecting hole 92 is processed, the supporting ring 17 and the positioning rod are driven upward by the material-repelling cylinder 3 18 and pushed into the connecting hole 92. At this time, the drill bit 14 is driven by the linear slide 12 to process the hydraulic hole, thereby increasing the processing stability and preventing the blank body 90 from vibrating during the processing of the hydraulic hole. An inclined conical surface is provided at the end of the positioning rod. When the material-repelling cylinder 3 18 drives the positioning rod to move, the inclined conical surface prevents the blank body 90 and the positioning rod from getting stuck.

[0029] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
