Description

Technical Field

[0001] This utility model relates to the field of riveting technology for covered housings, specifically a riveting fixture for covered housings. Background Technology

[0002] Riveting capped housings typically requires a specialized riveting gun, which is currently expensive. When the number of rivets to be riveted is small, using this gun can make the cost prohibitively high. Furthermore, the product has a spring-loaded upper and lower housing structure, making proper securing impossible. Traditional tooling can easily damage the product, resulting in wasted time and effort.

[0003] A search of existing technology reveals that publication number CN109420731B discloses a riveting mold. It includes a base with a clamping block positioning groove in the center. The clamping block slides vertically within the clamping block positioning groove, which is an inverted conical groove. The clamping block is an inverted conical body that mates with the clamping block positioning groove. The clamping block includes a right half-clamping block and a left half-clamping block that mates with the right half-clamping block. A clamping groove is provided at the connection between the right and left half-clamping blocks, consisting of a right half-clamping groove on the right half-clamping block and a left half-clamping groove on the left half-clamping block.

[0004] The prior art document describes a riveting process where, during riveting, the clamping block moves downward in the clamping block positioning groove, and the right and left halves of the clamping block move towards each other, clamping the rivet in the groove. After riveting, the clamping block moves upward in the clamping block positioning groove, and the right and left halves of the clamping block move away from each other, releasing the rivet from the groove. This invention has a simple structure, effectively avoids rivet deformation during riveting, and facilitates the insertion of the rivet before riveting and the removal of the riveted product after riveting. However, it cannot be used to rivet items with complex internal structures. Utility Model Content

[0005] The purpose of this utility model is to provide a riveting fixture for a covered housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including an upper mold and a lower mold, wherein a fixing groove is provided on the lower surface of the upper mold, a limiting groove is provided on the upper surface of the lower mold, threaded grooves are provided on both the left and right sides of the lower mold, and limiting grooves are provided on both the front and rear sides of the upper mold, a top cover is installed inside the upper mold, and an insertion rod is provided inside the lower mold.

[0007] Preferably, the top cover has extension pieces on both sides, and the top cover has a riveting groove inside, with a support spring and a washer inside the riveting groove.

[0008] Preferably, the lower mold has a through hole inside, one end of which is connected to a limiting groove. The shape of the limiting groove is adapted to the shape of the top cover. An insertion rod is slidably connected inside the through hole, and the insertion rod is adapted to the riveting groove.

[0009] Preferably, the limiting groove is positioned horizontally above the extension piece, and a bolt is slidably connected inside the limiting groove.

[0010] Preferably, the upper mold has through slots on its left and right sides, the through slots are located directly above the threaded slots, and fastening screws are threaded into the threaded slots.

[0011] Compared with existing technologies, the advantages of this utility model are: it provides a purely manual riveting fixture for single-specification covered housings that is simple to operate, safe and reliable, convenient to use, and low in cost, while ensuring riveting quality, efficiency, and consistency. It solves the problems of high cost, cumbersome installation, and time-consuming and labor-intensive manual alignment associated with existing riveting guns for riveting a small number of rivets. When riveting a covered housing, first place the top cover inside the upper mold, then place the support spring and washer inside the top cover. Next, place the upper mold cover on the lower mold and place the insertion rod inside the lower mold. Close the upper and lower molds by tightening the screws. Then insert the bolt and press the cover plate to rivet the two together. Attached Figure Description
