Description

[0003] The existing technology usually places the brake base plate securely on the workbench to ensure that it can stably withstand the next operation; then, we will drive the clamps to start relative movement, and these clamps will gradually approach the surface of the brake base plate under precise mechanical control; when the surface of the clamps is in close contact with the surface of the brake base plate, they will firmly fix the brake base plate on the workbench through the clamping force generated; in this way, we can perform various required processing operations on the fixed brake base plate;

[0004] However, in the processing of the brake base plate, it is often necessary to perform fine processing on the bottom end of the brake base plate; but the existing technology will encounter some efficiency problems when performing this step; specifically, when we need to process the bottom end of the brake base plate, we must first cancel the clamping of the brake base plate; this means that we need to stop the current processing flow, adjust the position of the fixture, and then re-clamp the brake base plate; this not only increases the complexity of the operation, but also significantly reduces the overall processing efficiency.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 6As shown, the utility model provides a processing fixture for a brake bottom plate of an automobile brake, comprising a base 1, and a fixing plate 2 is fixedly installed at both left and right ends of the base 1;

[0025] A rotating mechanism is arranged inside the fixed plate 2, and the rotating mechanism includes a screw rod 3, which is rotatably connected to the inside of the right-end fixed plate 2, and a limit rod 4 is fixedly installed inside the left-end fixed plate 2. The surface of the limit rod 4 is slidably connected with a moving block 5, and the surface of the screw rod 3 is threadedly connected with a moving block 2 6. The bottom end of the surface of the screw rod 3 is fixedly sleeved with a worm gear 7, and the right side of the right-end fixed plate 2 is fixedly installed with a motor 8, and the output end of the motor 8 is fixedly installed with a worm 9. The opposite sides of the moving block 2 6 are rotatably connected with a rotating rod 10, and a square shell 11 is fixedly installed on the top of the base 1, and a gear 12 located inside the square shell 11 is fixedly installed on the surface of the left-end rotating rod 10, and a connecting rod 13 is fixedly installed inside the square shell 11, and a rack 14 is fixedly installed on the top of the front side of the connecting rod 13.

[0026] The above scheme is adopted: after the brake base plate is fixed and the bottom side of the brake base plate needs to be processed, the motor 8 can be driven to rotate the worm 9. Because the worm 9 is meshed with the worm wheel 7, the worm 9 drives the worm wheel 7 to rotate, and then the worm wheel 7 drives the screw rod 3 to rotate. Because the screw rod 3 is threadedly connected with the moving block 2 6, when the screw rod 3 rotates, it will drive the moving block 2 6 to rise, and then the moving block 2 6 will drive the two rotating rods 10 and the moving block 1 5 to rise, and then the rotating rod 10 at the left end will drive the gear 12 to rise. When the gear 12 moves to the bottom end of the rack 14, because the gear 12 is meshed with the rack 14, when the gear 12 moves, it will rotate, and then the gear 12 will drive the brake base plate to rotate one hundred and eighty degrees, and then the operator can process the bottom side of the brake base plate.

[0027] like Figure 3 As shown, a fixing box 18 is fixedly installed on the opposite side of the rotating rod 10, and a spring assembly 23 is elastically connected inside the fixing box 18. A clamp body 22 is fixedly installed on the opposite side of the spring assembly 23. A U-shaped plate 21 is fixedly installed at the rear end of the clamp body 22. A motor 19 is fixedly installed inside the fixing box 18, and a screw rod 20 is fixedly installed on the output end of the motor 19. One end of the screw rod 20 passes through the surface of the U-shaped plate 21 and is threadedly connected to the U-shaped plate 21.

[0028] The above scheme is adopted: the screw rod 20 is rotated by driving the motor 2 19, because the screw rod 20 is threadedly connected to the U-shaped plate 21, and when the screw rod 20 rotates, the U-shaped plate 21 will be driven to move relatively, and then the U-shaped plate 21 will drive the clamp body 22 to move relatively. When the clamp body 22 moves, the spring assembly 23 will stretch, and then the clamp body 22 will be limited, and then the surface of the clamp body 22 will contact the surface of the brake base plate, thereby clamping and fixing the brake base plate.

[0029] like Figure 3 As shown, the surface of the clamp body 22 is designed to be curved, and the surface of the clamp body 22 is rough.

[0030] The above solution is adopted: through the design of the clamp body 22, when the clamp body 22 contacts the brake base plate, because the clamp body 22 is designed with an arc and a rough surface, it will increase the friction with the brake base plate, thereby preventing the brake base plate from falling off when it rotates.

[0031] like Figure 5 As shown, a cylinder 15 is fixedly installed inside the base 1 , a connecting block 17 is fixedly installed on the output shaft of the cylinder 15 , and a workbench 16 is fixedly installed on the top of the connecting block 17 .

[0032] The above scheme is adopted: through the design of the cylinder 15, the workbench 16 and the connecting block 17, after the brake base plate rotates one hundred and eighty degrees, the cylinder 15 can be driven, and then the output shaft of the cylinder 15 will push the connecting block 17 to move, and then the connecting block 17 will drive the workbench 16 to move, and then the bottom end of the workbench 16 will contact the surface of the brake base plate, thereby supporting the brake base plate, thereby facilitating the processing of the brake base plate.

[0033] like Figure 2 As shown, the limiting rod 4 is cylindrical in design, the surface of the limiting rod 4 is smooth, and both ends are fixedly connected to the top and bottom ends inside the fixing plate 2.

[0034] The above solution is adopted: through the design of the limiting rod 4, because the surface of the limiting rod 4 is designed to be smooth, the moving block 1 5 can move more smoothly on the surface of the limiting rod 4.

[0035] like Figure 5 As shown, the surface of the connecting block 17 is in contact with the inner wall of the base 1, and the two ends of the bottom end of the connecting block 17 are designed to be outward-facing.

[0036] The above solution is adopted: through the design of the connecting block 17, when the connecting block 17 enters the interior of the base 1, the outward-facing eight-shaped design can greatly reduce the resistance during entry, so that the connecting block 17 can enter the interior of the base 1 more smoothly and easily.

[0037] like Figure 4As shown, a through groove is provided on the surface of the square shell 11 , and the left end rotating rod 10 can move inside the square shell 11 .

[0038] With the above solution, through the design of the square shell 11 , when the left end rotating rod 10 moves, it will move inside the through slot, and thus the square shell 11 will not interfere with the movement of the rotating rod 10 .

[0039] The working principle and use process of this utility model:

[0040] First, the operator can place the brake base plate on the top of the workbench 16, and then drive the motor 2 19 to rotate the screw 20, and then the screw 20 will drive the U-shaped plate 21 and the clamp body 22 to move relative to each other, and then the surface of the clamp body 22 will contact the surface of the brake base plate, and then clamp the brake base plate, and then the operator can process the top of the brake base plate. When it is necessary to process the bottom side, the motor 1 8 can be driven to rotate the worm 9, and the worm 9 will drive the worm wheel 7 to rotate, and then the worm wheel 7 will drive the screw 1 3 to rotate, and the screw 1 3 will drive the moving block 2 6 to move up, and then the moving block 2 6 drives the two clamps The main body 22 and the brake base plate being clamped by the clamp body 22, when the two clamp bodies 22 move, the gear 12 at the left end will move inside the square shell 11, and then the surface of the gear 12 will contact the bottom end of the rack 14, and then when the gear 12 moves, it will rotate, and then the gear 12 will drive the clamp body 22 and the brake base plate to rotate one hundred and eighty degrees. After the rotation is completed, the output shaft of the cylinder 15 will push the connecting block 17 and the workbench 16 to move, and then the bottom end of the workbench 16 will contact the surface of the brake base plate, thereby supporting the brake base plate, and then the operator can process the bottom end of the brake base plate.
