Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, in particular to a device which can effectively prevent rivet nuts from leaking out of automobile bumpers. Background Art

[0002] The production process of the anti-collision beam assembly is: roller pressing - spot welding - cutting - riveting - second protection welding - repair welding - slag cleaning - packing. In the riveting process, it is easy to have accidents of multiple rivets and unqualified parts due to missed processes being transferred to the downstream, which poses a great hidden danger to vehicle matching and automobile safety. Due to the large weight of a single piece and the long rivet hole position, it is closely related to the proficiency and awareness of the operators. Therefore, multiple rivets and unqualified parts due to missed processes being transferred to the downstream frequently occur when new employees take up their posts and take over the job.

[0003] The existing methods for preventing automobile bumpers from missing rivet nuts are generally: 1. Relying solely on manual inspection, this method increases the workload of operators and is effective in the short term. However, operators are prone to mechanical movements during long-term production. When workers are tired or new employees are negligent in their work, there is a small probability that multiple rivets or unqualified parts that have missed processes will be transferred to the next step; 2. This can be achieved by replacing fully automatic equipment, screening the riveted products through CCD, and then transferring the product parts. However, this solution is expensive, and the actual operation is greatly affected by other variables, and it will affect the production rhythm, making it difficult to implement. Therefore, it is very necessary to design a device that can reduce labor intensity, facilitate parts circulation, prevent product deformation, and is low-cost and easy to implement to prevent automobile bumpers from missing rivet nuts.

[0036] When in use, the operator first presses the start button 13 to start the pneumatic cylinder 9, thereby driving the upper clamp 6 to rotate upward, and then separating the lower clamp 4 and the upper clamp 6. At this time, the operator places the car bumper on the upper surface of the lower clamp 8, so that the two support blocks 17 can support the bumper from both ends of the car bumper. Then the operator presses the clamping button 14 to make the pneumatic cylinder 9 drive the upper clamp 6 to rotate downward, so that the upper clamp 7 and the lower clamp 8 cooperate to clamp and fix the car bumper, so that when the operator performs riveting operations on the car bumper, the problem of unqualified parts due to over-riveting and missed processes being transferred to the next sequence can be avoided.
