Technical Field
[0001] This utility model relates to the field of car door hinges, specifically to a riveting fixture for car door hinge products. Background Technology
[0002] A car door hinge is a mechanical device, also known as a hinge, door hinge, or door hinge, mainly used to connect the car door and the car body to realize the opening and closing of the car door. The riveting fixture for car door hinge products is a process equipment specifically used for riveting car door hinge components. It can improve riveting efficiency and ensure the fixed position and assembly accuracy of the hinge.
[0003] Currently, most existing door hinge products still rely on manual pressing for fixation, followed by riveting by a riveting machine. However, manual pressing poses certain risks. While some existing door hinge products use cylinders for positioning and fixing, these methods are mostly simple and result in poor riveting stability, making them prone to loosening and shifting.
[0004] Therefore, it is necessary to invent a riveting fixture for car door hinge products to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a riveting fixture for car door hinge products. When the main body of the car door hinge is placed on the placement frame, the first cylinder switch is turned on, pushing the connecting plate and the pressure block to clamp the front side of the car door hinge main body. When the connecting plate moves telescopically, it causes the oblique angle of the fixing block on one side to fit and overlap with the oblique angle of the inner side of the clamping block, thereby pushing the clamping block to clamp and position the left side of the car door hinge main body. This can quickly clamp the front and left sides, improving the efficiency and stability of clamping and positioning, thus solving the problem mentioned in the background art of existing car door hinge product riveting fixtures. Currently, most of them still use manual pressing to fix, and then use riveting machinery to press down to rivet the hinge product. However, manual pressing has certain dangers. At the same time, some existing car door hinge product riveting fixtures also have cylinder-driven positioning and fixing, but most of them are simple positioning and fixing of the car door hinge product, which has poor riveting stability and is prone to loosening and displacement problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a riveting fixture for a car door hinge product, including a fixture base for assembling the riveting fixture;
[0007] The first clamping mechanism and the second clamping mechanism are installed above the tooling base for clamping and positioning. The first clamping mechanism includes a first cylinder and a pressure block, and the second clamping mechanism includes a fixed base and a clamping block.
[0008] A placement rack is set above a tooling base. The outer surface of the placement rack has a placement groove. The placement rack is fitted with a placement groove. A mounting slide is fixedly connected to the upper right side of the tooling base. A frame is slidably connected to the outside of the mounting slide. A motor is installed inside the frame. A rivet joint is fixedly connected to the output end of the motor. A second cylinder is installed on the rear side of the frame.
[0009] Preferably, the first cylinder is fixed above the rear side of the tooling base, the output end of the first cylinder is fixedly connected to a connecting plate, the front side of the connecting plate is fixedly connected to a pressure block, and a rubber pad is provided on the outside of the pressure block.
[0010] Preferably, a fixing block is fixedly connected to the left side of the connecting plate, and the inner side of the fixing block is set at an angle.
[0011] Preferably, a fixing frame is provided on both sides above the tooling base and below the connecting plate, a slide rail is fixedly connected to the top of the fixing frame, a slider is slidably connected to the outside of the slide rail, and the slider is fixedly connected to the connecting plate.
[0012] Preferably, the fixing seat is fixed on the upper left side of the tooling base, a connecting rod is fixedly connected inside the fixing seat, a moving block is sleeved on the outside of the connecting rod, a spring is provided on the right side of the moving block and outside the connecting rod, and a clamping block is fixedly connected above the moving block.
[0013] Preferably, the left side of the clamping block is set at an angle, and the left side of the clamping block overlaps with the inner corner of the fixing block.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. By setting up the first clamping mechanism and the second clamping mechanism, a set of first cylinders can simultaneously drive the pressure block and the clamping block to clamp and position the main body of the door hinge, which improves the stability and efficiency of clamping and positioning. When the main body of the door hinge is placed on the placement rack, the first cylinder switch is turned on, pushing the connecting plate and the pressure block to clamp the front side of the main body of the door hinge. When the connecting plate moves in extension and retraction, it drives the oblique angle of the fixed block on one side to fit and overlap with the oblique angle of the inner side of the clamping block, thereby pushing the clamping block to clamp and position the left side of the main body of the door hinge. This enables quick clamping on the front and left sides, improving the efficiency and stability of clamping and positioning.
[0016] 2. By setting up a placement rack, placement slot, door hinge body, mounting slide, frame, rivet head, and second cylinder, traditional riveting fixtures compact from top to bottom. However, left-right compaction riveting can be performed in confined spaces, avoiding interference from vertical forces on surrounding structures. At the same time, due to its flexible operation direction, left-right compaction riveting can adapt to hinge products of different shapes and sizes. The door hinge body is positioned by placing it in the placement slot on the placement rack. Then, the first and second clamping mechanisms clamp and position the door hinge body. After that, the motor switch inside the frame is turned on, driving the rivet head to rotate. Then, the second cylinder switch is turned on, pushing the entire frame to move on the mounting slide, so that the rivet head is aligned with the right side of the door hinge body for compaction riveting.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-6 The riveting fixture shown includes a fixture base 1 for assembling the riveting fixture.
[0028] The first clamping mechanism 2 and the second clamping mechanism 3 are installed above the tooling base 1 for clamping and positioning. The first clamping mechanism 2 includes a first cylinder 201 and a pressure block 203, and the second clamping mechanism 3 includes a fixed base 301 and a clamping block 305.
[0029] A placement rack 4 is positioned above the tooling base 1. A placement groove 5 is formed on the outer surface of the placement rack 4, and the placement groove 5 is fitted onto the outside of the placement rack 4. A mounting slide 7 is fixedly connected to the upper right side of the tooling base 1. A frame 8 is slidably connected to the outside of the mounting slide 7. A motor is installed inside the frame 8, and a rivet joint 9 is fixedly connected to the output end of the motor. A second cylinder 10 is installed on the rear side of the frame 8. When the door hinge body 6 is placed on the placement rack 4, the switch of the first cylinder 201 is turned on, pushing the connecting plate 202 and the pressure block 203 to clamp the front side of the door hinge body 6. When the connecting plate 202 moves in extension and retraction, it causes the oblique angle of the fixing block 205 on one side to fit and overlap with the oblique angle of the inner side of the clamping block 305, thereby pushing the clamping block 305 to clamp and position the left side of the door hinge body 6. This enables quick clamping on the front and left sides, improving the efficiency and stability of clamping and positioning.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the first cylinder 201 is fixed on the rear side above the tooling base 1. The output end of the first cylinder 201 is fixedly connected to the connecting plate 202. The front side of the connecting plate 202 is fixedly connected to the pressure block 203. The outside of the pressure block 203 is provided with a rubber pad 204. By turning on the switch of the first cylinder 201, the connecting plate 202, the pressure block 203 and the rubber pad 204 are pushed to stick to the front side of the door hinge body 6 for clamping and positioning. The setting of the rubber pad 204 can prevent the door hinge body 6 from being scratched during the clamping process.
[0031] like Figure 2 and Figure 3 As shown, a fixing block 205 is fixedly connected to the left side of the connecting plate 202. The inner side of the fixing block 205 is set at an angle. When the connecting plate 202 moves in a telescopic manner, it can drive the fixing block 205 on the left side to telescopically move, thereby driving the clamping block 305 to move and complete the overall clamping and positioning.
[0032] like Figure 3As shown, a fixing frame 206 is provided on both sides above the tooling base 1 and below the connecting plate 202. A slide rail 207 is fixedly connected to the top of the fixing frame 206. A slider 208 is slidably connected to the outside of the slide rail 207. The slider 208 is fixedly connected to the connecting plate 202. When the connecting plate 202 is pushed by the first cylinder 201, the slider 208 below the connecting plate 202 slides outside the slide rail 207, thereby improving the stability of the connecting plate 202 during telescopic movement.
[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the fixed base 301 is fixed on the upper left side of the tooling base 1. A connecting rod 302 is fixedly connected inside the fixed base 301. A moving block 303 is sleeved on the outside of the connecting rod 302. A spring 304 is provided on the right side of the moving block 303 and the outside of the connecting rod 302. A clamping block 305 is fixedly connected above the moving block 303. The clamping block 305 and the moving block 303 can slide on the connecting rod 302 inside the fixed base 301. The inner spring 304 can play a telescopic rebound role. When the fixed block 205 telescopically retracts through the connecting plate 202, the clamping block 305 loses the compression of the fixed block 205. The rebound action of the spring 304 causes the clamping block 305 to release the door hinge body 6.
[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the left side of the clamping block 305 is set at an angle, and the left side of the clamping block 305 overlaps with the inner corner of the fixing block 205. When the connecting plate 202 moves in extension and retraction, it drives the angle of the fixing block 205 on one side to fit and overlap with the angle of the inner side of the clamping block 305, thereby pushing the clamping block 305 to clamp and position the left side of the door hinge body 6.
[0035] The working principle of this utility model is as follows: First, connect the external power supply. Then, place the door hinge body 6 to be riveted on the placement bracket 4 on the tooling base 1. After placement, turn on the first cylinder 201 switch to push the connecting plate 202 and the pressure block 203 to clamp the front side of the door hinge body 6. When the connecting plate 202 moves telescopically, it causes the oblique angle of the fixing block 205 on one side to fit and overlap with the oblique angle of the inner side of the clamping block 305, thereby pushing the clamping block 305 to clamp and position the left side of the door hinge body 6. This allows for quick clamping on the front and left sides, improving the efficiency and stability of clamping and positioning. After the door hinge body 6 is clamped and positioned, turn on the motor inside the frame 8 to drive the frame 8 to rotate. Then, turn on the second cylinder 10 switch to push the frame 8 and the riveting joint 9 to slide on the mounting slide 7. The device moves, causing the rivet head 9 to slide and rotate to rivet the right side of the door hinge body 6 where it needs to be riveted. After riveting is completed, the second cylinder 10 switch is turned off, and the frame 8 and rivet head 9 are extended and retracted. Then, the first cylinder 201 switch is turned off, and the connecting plate 202 and the pressure block 203 are extended and retracted to loosen the front side of the door hinge body 6. When the fixing block 205 is extended and retracted through the connecting plate 202, the clamping block 305 loses the pressure of the fixing block 205. The spring 304 rebounds, causing the clamping block 305 to loosen the door hinge body 6. Finally, the riveted door hinge body 6 is taken out, and then the next door hinge body 6 that needs to be riveted is placed in. When the device is no longer in use, the external power is cut off. This completes the use process of the riveting fixture for the door hinge product.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
