Description

Technical Field

[0001] This utility model relates to the field of rivet nuts, and more specifically, to a clamping device for rivet nuts. Background Technology

[0002] Rivet nuts, also known as pull nuts or rivet caps, are used in the fastening of various metal sheets and pipes in the manufacturing industry. They are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. Developed to address the shortcomings of welding nuts on thin metal sheets and pipes, such as easy melting, easy deformation of the base material during welding, and easy stripping of internal threads, rivets eliminate the need for tapping internal threads and welding nuts, providing strong and efficient riveting and ease of use.

[0003] The processing of conventional rivet nuts requires clamping equipment, which can clamp and fix the rivet nut blank. After the conventional clamping equipment clamps and fixes the rivet nuts, it is usually necessary to manually remove the rivet nuts one by one. This cannot effectively achieve the unified collection of multiple rivet nuts and is not conducive to improving processing efficiency. Therefore, we have made improvements and proposed a clamping device for rivet nuts. Summary of the Invention

[0004] The purpose of this utility model is to provide a clamping device for rivet nuts, which solves the problem that the existing clamping device for rivet nuts cannot effectively collect multiple rivet nuts in a unified manner during use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A clamping device for riveting nuts includes a platform, a track box fixedly connected above the platform, a nut fixing platform slidably connected to the track box, a nut fixing seat fixedly connected to the nut fixing platform, the bottom of the nut fixing seat being hollowed out, and the surface of the track box also having a hollowed-out groove corresponding to the bottom wall of the nut fixing seat.

[0007] Two clamps are slidably connected to each side of the storage platform, and a drive unit is connected between the two clamps.

[0008] As a preferred technical solution of this application, the drive unit includes a toothed rod fixedly connected to the surface of the clamp plate. Both toothed rods penetrate the interior of the storage platform, and a height gap is formed between the two toothed rods located inside the storage platform. A gear is provided in the height gap.

[0009] The gear is movably connected to the side wall of the platform via bearings, and the top and bottom of the gear mesh with the corresponding rack.

[0010] As a preferred technical solution of this application, table legs are fixedly connected to the four corners of the bottom of the storage platform, and extension plates are fixedly connected to the two table legs at the front end of the storage platform. A storage box is connected to the upper end of the extension plate.

[0011] As a preferred technical solution of this application, a limiting rod is inserted below each corresponding toothed rod of the storage platform, and a limiting groove is formed on the surface of the toothed rod located inside the storage platform;

[0012] The sliding limit rod can be inserted into the limit groove at one end to fix the toothed rod.

[0013] As a preferred technical solution of this application, the track box includes a box body and slide rails distributed on the top of the box body. A drop groove is provided on one side of the top of the box body, and the nut fixing seat is slidably assembled with the box body through the slide rails.

[0014] The sliding nut holder can be moved above the drop groove to allow the rivet nut to fall into the storage box.

[0015] As a preferred technical solution of this application, an L-shaped block is fixed to the front end of the nut fixing seat, and a buffer pad is fixed to the end of the L-shaped block.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. With the storage box, after the rivet nuts are clamped and processed, when the nut fixing table is pushed along the slide rail to the drop groove, the rivet nuts fall into the storage box through the hollow nut fixing seat at the bottom. This eliminates the need to take out multiple rivet nuts one by one, making it convenient to collect the rivet nuts after slotting.

[0019] 2. By fixing multiple nut fixing seats to the nut fixing platform, multiple rivet screw seats can be fixed simultaneously when the bolts are slotted in the clamping plate, thereby achieving uniform slotting of multiple rivet nuts. Attached Figure Description

[0034] like Figures 1-5 As shown, this embodiment proposes a clamping device for riveting nuts, including a storage platform 1, a track box 2 fixedly connected above the storage platform 1, a nut fixing platform 3 slidably connected on the track box 2, a nut fixing seat 4 fixedly connected on the nut fixing platform 3, the bottom of the nut fixing seat 4 being hollowed out, and the surface of the track box 2 also having a hollowed-out groove 24 corresponding to the bottom wall of the nut fixing seat 4.

[0035] Two clamping plates 6 are slidably connected to both sides of the storage platform 1, and a drive unit 5 is connected between the two clamping plates 6.

[0036] like Figure 1 As shown, the outer side of the clamping plate 6 is provided with a processing groove. Through this processing groove, when the clamping plate 6 fixes the rivet nut, the inner side of the clamped rivet nut can be processed from the outside.

[0037] The drive unit 5 includes a rack 51 fixedly connected to the surface of the clamping plate 6. Both racks 51 penetrate the interior of the storage platform 1, and a height gap 52 is formed between the two racks 51 inside the storage platform 1. A gear 53 is provided in the height gap. The gear 53 is movably connected to the side wall of the storage platform 1 through a bearing, and the top and bottom of the gear 53 mesh with the corresponding rack 51.

[0038] Table legs 11 are fixedly connected to the four corners of the bottom of the storage platform 1. An extension plate 7 is fixedly connected to the two table legs 11 at the front end of the storage platform 1. A storage box 8 is connected to the upper end of the extension plate 7. In this embodiment, the storage box 8 is placed on the extension plate 7, so that the rivet nuts that fall from above can be collected in a unified manner. After collection, the storage box 8 can be removed and the rivet nuts inside can be transferred synchronously to the next process.

[0039] Each of the corresponding toothed rods 51 on the storage platform 1 is inserted with a limiting rod 54. A limiting groove 55 is formed on the surface of the toothed rod 51 located inside the storage platform 1. The sliding limiting rod 54 can insert one end into the limiting groove 55 to fix the toothed rod. There are multiple limiting grooves 55, and the portions of the multiple limiting grooves 55 are equidistant from each other on the limiting rod 54.

[0040] The track box 2 includes a box body 21 and slide rails 22 distributed on the top of the box body 21. A drop groove 23 is provided on one side of the top of the box body 21. The nut fixing seat 4 is slidably assembled with the box body 21 through the slide rail 22. The sliding nut fixing platform 3 can be moved above the drop groove 23 so that the riveted nut can fall into the storage box 8.

[0041] The above plan will be further described below with reference to specific working methods:

[0042] Specifically, when using this rivet nut clamping device: when the rivet nut needs to be processed, first push the nut fixing platform 3 to the area of ​​the box 21, then place the rivet nut on the nut fixing seat 4, push the rack 51 inward, and the rack 51 will mesh with the gear 53. The meshing gear 53 will rotate and form a transmission with the other rack 51 on one side, so that the two clamping plates 6 can move closer or further away from each other. When the clamping plate 6 touches the outside of the rivet nut, the clamping is completed. The rivet nut to be processed can be fixed by inserting the limiting rod 54 through the groove and limiting groove 55 on the placement platform 1.

[0043] When the riveting nut is finished, pull out the limit rod 54, then pull the toothed rod 51 outward, and then slide the nut fixing platform 3 so that the nut fixing platform 3 is on the drop groove 23. At this time, the finished riveting nut will fall into the storage box 8, completing the unified collection of multiple riveting nuts, which is conducive to improving processing efficiency.
