Description

Technical Field

[0001] This utility model relates to the field of automotive crossbeam riveting technology, specifically to an automotive crossbeam assembly positioning and riveting fixture. Background Technology

[0002] Currently, there are two main scenarios for installing automotive crossbeams: one is during overall assembly in automobile production, and the other is during later automotive repair. In current intelligent production workshops, intelligent robotic arms are used at workstations to move and assemble parts during final assembly. However, in automotive repair, crossbeams are mostly assembled manually. When using robotic arms to assemble crossbeams, the robotic arm typically needs to hold the crossbeam in a fixed position before riveting at multiple locations. Riveting takes time, causing the robotic arm to spend considerable time on this step, thus delaying the assembly of other parts and reducing its efficiency. Similarly, manually stabilizing the crossbeam during repair also consumes significant human resources. Therefore, there is a lack of appropriate positioning and support fixtures for automotive crossbeam assembly. This paper proposes a positioning and riveting fixture for automotive crossbeam assembly. Utility Model Content

[0003] The purpose of this utility model is to solve the problem of the lack of corresponding positioning and support fixtures during the assembly of automobile crossbeams. This utility model provides a positioning and riveting fixture for automobile crossbeam assembly.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A positioning and riveting fixture for automotive crossbeam assembly includes a base plate. A support block is fixedly installed on the upper side of the base plate, and a receiving groove is formed on the side wall of the support block. A support bearing is embedded in the receiving groove, and a connecting block is fixedly inserted into the support bearing. A first electric push rod is fixedly installed on the connecting block, and a locking ring is fixedly installed on the periphery of the first electric push rod. A fastening mechanism is provided on the support block on one side of the locking ring. A rotating mechanism is fixedly installed at one end of the first electric push rod, and an assembly block is provided on the rotating mechanism. A second electric push rod is fixedly installed on the assembly block, and an adsorption connection mechanism is fixedly installed at one end of the second electric push rod.

[0006] Preferably, the fastening mechanism includes an axial plate, which is fixedly mounted on a support block, and a push spring is provided on the support block. A brake pad is fixedly mounted on one end of the push spring, and the brake pad abuts against the side wall of the locking ring.

[0007] Preferably, the rotating mechanism includes a U-shaped frame, which is mounted on the first electric push rod. The U-shaped frame has a rotating hole, and a connecting shaft is rotatably installed in the rotating hole. Positioning round plates are fixedly installed at both ends of the connecting shaft, and the assembly block is fixedly installed on the connecting shaft.

[0008] Preferably, a vertical support plate is fixedly installed on the side wall of the U-shaped frame, and a compression spring is fixedly installed on the side wall of the vertical support plate. An arc-shaped brake plate is fixedly installed at one end of the compression spring, and the arc-shaped brake plate abuts against the side wall of the positioning circular plate.

[0009] Preferably, a connecting sleeve is fixedly installed on the U-shaped frame, and the connecting sleeve is slidably mounted on the first electric push rod.

[0010] Preferably, the adsorption connection mechanism includes an expansion box, one side of which is fixedly mounted on a second electric push rod, and multiple adsorption nozzles are provided on the side wall of the expansion box. An air pump is fixedly mounted on the side wall of the expansion box and is connected to the inside of the expansion box.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, when a car crossbeam needs to be assembled during the production or later maintenance of a car, the base plate is fixed on the work station, and then the locking ring is rotated to make the first electric push rod rotate to a suitable angle. Then, the brake pad is used to tighten it. Next, the tooling is adjusted to a reasonable height by controlling the first electric push rod. At the same time, the support elevation angle can be adjusted by the connecting shaft on the U-shaped frame. Then, the second electric push rod on the assembly block is started to drive the expansion box to press against the car crossbeam. Then, the air pump is started to create negative pressure in the expansion box, so that the car crossbeam can be adsorbed onto the expansion box through the suction nozzle. This allows the robotic arm and manual support during the riveting process to be removed, which helps to improve the overall assembly efficiency of the car. Attached Figure Description

[0021] like Figure 1-3As shown, a positioning and riveting fixture for automotive crossbeam assembly includes a base plate 1. A support block 2 is fixedly installed on the upper side of the base plate 1, and a receiving groove 20 is provided on the side wall of the support block 2. A support bearing 21 is embedded in the receiving groove 20, and a connecting block is fixedly inserted into the support bearing 21. A first electric push rod 4 is fixedly installed on the connecting block, and a locking ring 3 is fixedly installed on the periphery of the first electric push rod 4. The locking ring 3 allows the first electric push rod 4 to be manually pushed and its angle adjusted by means of the support bearing 21.

[0022] A fastening mechanism is provided on one side of the locking ring 3 on the support block 2. The fastening mechanism includes an axial plate 5, which is fixedly installed on the support block 2. A push spring 6 is provided on the support block 2, and a brake pad 7 is fixedly installed on one end of the push spring 6, with the brake pad 7 in contact with the side wall of the locking ring 3. The brake pad 7 helps to maintain the stability of the locking ring 3 after the angle is adjusted.

[0023] A rotating mechanism is fixedly installed at one end of the first electric push rod 4. The rotating mechanism includes a U-shaped frame 9, which is set on the first electric push rod 4. A rotating hole is opened on the U-shaped frame 9, and a connecting shaft 10 is rotatably installed in the rotating hole. Positioning round plates 14 are fixedly installed at both ends of the connecting shaft 10. An assembly block 15 is set on the connecting shaft 10, and a second electric push rod 16 is fixedly installed on the assembly block 15. The connecting shaft 10 on the U-shaped frame 9 allows the entire tooling to be adjusted for support angle, thereby better supporting the automobile crossbeam.

[0024] A vertical support plate 12 is fixedly installed on the side wall of the U-shaped frame 9, and a compression spring 13 is fixedly installed on the side wall of the vertical support plate 12. An arc-shaped brake plate 11 is fixedly installed at one end of the compression spring 13, and the arc-shaped brake plate 11 abuts against the side wall of the positioning circular plate 14.

Then, the air pump 19 is activated to create a negative pressure inside the expansion box 17, so that the car crossbeam can be adsorbed onto the expansion box 17 through the adsorption nozzles 18, thereby maintaining the stability of the car crossbeam during the assembly process.

[0026] In summary: When a car needs to be assembled with a crossbeam during production or maintenance, the base plate 1 is fixed at the designated work station. Then, the locking ring 3 is rotated so that the first electric push rod 4 rotates to a suitable angle through the support bearing 21. Then, the push spring 6 drives the brake plate 7 to press against the locking ring 3 for fastening. Next, the first electric push rod 4 is activated to control the tooling to adjust to a reasonable height. At the same time, the connecting shaft 10 on the U-shaped frame 9 can drive the assembly block 15 to adjust the support angle. Then, the clamping spring 13 drives the arc brake plate 11 to lock the positioning round plate 14 to prevent it from rotating arbitrarily. Next, the second electric push rod 16 on the assembly block 15 is activated to drive the expansion box 17 to press against the car crossbeam. Then, the air pump 19 is activated to create negative pressure in the expansion box 17, so that the car crossbeam can be adsorbed onto the expansion box 17 through the suction nozzle 18, thereby providing stable support for the car crossbeam during the riveting process.
