[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-7This utility model provides an embodiment: a multi-station fixture for automotive brake caliper brackets, including a frame 1; it also includes a bridge plate 2, clamp 1 3, clamp 2 4, clamping head 1 11, clamping head 2 13, clamping head 3 15, and a central clamping head 22. The bridge plate 2 is rotatably connected between the left and right sides of the frame 1. Four clamps 1 3 are installed on the top of the bridge plate 2, and four clamps 2 4 are installed on the bottom of the bridge plate 2. Cylinders 1 10 are installed on the lower ends of the left and right sides of the front of clamps 2 4. The output ends of the cylinders 1 10 are connected to clamping heads 1 11. Cylinders 1 10 are installed on the left and right sides of the top of clamps 2 4. Cylinder 2 (12) has a clamping head 2 (13) connected to its output end. Cylinder 3 (14) is mounted on the top rear side of clamp 2 (4). Cylinder 3 (14) has a clamping head 3 (15) connected to its output end. Hydraulic cylinder 16 is mounted inside the lower end of clamp 2 (4). Conical head 17 is connected to the output end of hydraulic cylinder 16. Connecting rod 18 is provided on both the left and right sides of the front end of conical head 17. Return spring 19 is connected to the outer side of connecting rod 18. Dust cover 20 is connected to the other end of return spring 19. Dust cover 20 is located on the left and right sides of clamp 2 (4). The other end of connecting rod 18 is connected to the dust cover 20. Connecting rod 21 is attached to the second end of the device, and a centering clamping head 22 is connected to the other end of the connecting rod 21. A positioning fixture 36 is connected between the centering clamping heads 22 via a keyway. The positioning fixture 36 is connected via a keyway, enabling quick replacement and facilitating the inspection of various products. After placing the workpiece, the hydraulic cylinder 16 is activated. The hydraulic cylinder 16 drives the conical head 17 to move forward. The conical head 17 then pushes the connecting rods 18 on both sides to move outward synchronously through its conical surface. The connecting rods 18 then push the connecting rod 21 to rotate around its axis. The other end of the connecting rod 21 can then... Pushing the centering clamping head 22 inward, the centering clamping head 22 can center and position the workpiece. Then, the second cylinder 12 and the third cylinder 14 are activated. The second cylinder 12 and the third cylinder 14 can drive the clamping heads 2 13 and 3 15 downward to perform three-point main fixation clamping on the workpiece. Finally, the first cylinder 10 is activated. The first cylinder 10 can drive the first clamping head 11 to move backward, so that the first clamping head 11 can perform two-point final fixation clamping on the workpiece, thereby ensuring reliable workpiece positioning and firm clamping. The setting of the return spring 19 facilitates the reset of the connecting rod 18.

[0026] Please see Figures 3-4In this embodiment, support blocks 1 5 are connected to the left and right sides of the front of clamp 2 4, support blocks 2 6 are connected to the left and right sides of the top of clamp 2 4, support block 3 7 is connected to the top of clamp 2 4, limit seats 8 are connected to the left and right ends of the inner back of clamp 2 4, and tilting head 9 is connected to the front of clamp 2 4. Support blocks 1 5 are correspondingly set with clamping head 1 11, support blocks 2 6 are correspondingly set with clamping head 2 13, and support blocks 3 7 are correspondingly set with clamping head 3 15. The arrangement of support blocks 1 5, support blocks 2 6 and support blocks 3 7 can cooperate with clamping head 1 11, clamping head 2 13 and clamping head 3 15 to clamp and fix the workpiece. The limit seats 8 and tilting head 9 can limit the workpiece. With the clamp, the phenomenon of the workpiece falling off when it is flipped can be avoided.

[0027] Please see Figures 1-7 In this embodiment, the output end of cylinder 3 14 is connected to an arc-shaped gas detection trigger block 23, which is located outside the clamping head 3 15. The top of clamp 1 3 is connected to a mounting base 33, which is located in front of the arc-shaped gas detection trigger block 23. A gas detection device 24 is threadedly connected inside the mounting base 33. A gas detection core 25 is provided inside the gas detection device 24, which is located in front of the arc-shaped gas detection trigger block 23. An annular block 26 is connected to the outside of the gas detection core 25. A return spring 27 is connected to the front side of the annular block 26. The other end of the return spring 27 is connected to the rear side of the inside of the gas detection device 24. A sealing ring 28 is sleeved on the front outer side of the gas detection core 25. A conical groove 29 is opened on the front side of the inside of the gas detection device 24. The conical groove 29 matches the sealing ring 28. An air inlet 30 is opened on the front inner side of the conical groove 29. An air inlet passage 31 is opened inside the mounting base 33. The air inlet 30 communicates with the air inlet passage 31. The rear side of the gas detection device 24 is opened... An exhaust port 32 is provided, which communicates with the interior of the air detection device 24. Cylinders 34 are connected to both the left and right ends of the outer side of clamp 3. The output end of cylinder 34 is connected to a clamping head 35. Activating cylinder 34 drives clamping head 35 to clamp and fix the workpiece on clamp 3. When clamping the workpiece on clamp 4 at three points, cylinder 314 synchronously drives the arc-shaped air detection trigger block 23 to move downwards. The arc-shaped air detection trigger block 23 pushes the air detection core 25. When the gas detector 25 moves forward, it can cause the sealing ring 28 to press against the conical groove 29 to seal the gas. At this time, the gas detection is qualified, indicating that there is no deviation in the workpiece position. When the arc-shaped gas detection trigger block 23 continues to move downward, the gas detector 25 moves backward under the action of the return spring 27. The sealing ring 28 separates from the conical groove 29, and the gas is discharged from the exhaust hole 32. At this time, the gas detector leaks, indicating that there is a deviation in the workpiece position, which can remind the personnel to adjust the workpiece.

[0028] During operation, after placing the workpiece, firstly, hydraulic cylinder 16 is activated. Hydraulic cylinder 16 drives conical head 17 to move forward. Conical head 17 then pushes connecting rods 18 on both sides to move outward simultaneously through its conical surface. Connecting rods 18 then push connecting rod 21 to rotate around its axis. The other end of connecting rod 21 pushes the centering clamping head 22 to move inward, thus centering and clamping the workpiece. Subsequently, cylinders 12 and 14 are activated. Cylinders 12 and 14 drive clamping heads 13 and 15 downward respectively to perform three-point main clamping of the workpiece. Finally, cylinder 10 is activated. Cylinder 10 drives clamping head 11 to move backward, thus... The system can perform two-point final clamping of the workpiece to ensure reliable workpiece positioning and secure clamping. During three-point positioning and clamping of the workpiece, cylinder 3 14 synchronously drives the arc-shaped gas detection trigger block 23 to move downward. The arc-shaped gas detection trigger block 23 pushes the gas detection core 25 forward. The gas detection core 25 then drives the sealing ring 28 to press against the conical groove 29 to seal the gas. At this time, the gas detection is qualified, indicating that there is no deviation in the workpiece position. When the arc-shaped gas detection trigger block 23 continues to move downward, the gas detection core 25 moves backward under the action of the return spring 27. The sealing ring 28 separates from the conical groove 29, and the gas is discharged from the exhaust hole 32. At this time, the gas detection leaks, indicating that there is a deviation in the workpiece position, thus reminding the personnel to adjust the workpiece.

[0029] Through the above steps, by setting up bridge plate 2, clamp 1 3, clamp 2 4, clamping head 1 11, clamping head 2 13, clamping head 3 15 and centering clamping head 22, this device is a four-station clamp. When clamping the workpiece, hydraulic cylinder 16, cylinder 2 12, cylinder 3 14 and cylinder 1 10 can clamp and fix the workpiece. The operation is simple and convenient, improving processing efficiency. The positioning fixture 36 is connected by a keyway, which can realize quick replacement and facilitate the testing of various products. This solves the problem that some existing clamps for automotive brake caliper brackets are mostly two-station clamps. In mass production, the downtime and clamping time of two-station processing is long, and the clamping operation and correction are cumbersome, requiring high technical skills from personnel, which reduces processing efficiency.
