Description

Technical Field

[0001] This utility model relates to the field of high-voltage switchgear manufacturing technology, specifically to a quick riveting auxiliary device for positioning rivets on the end plate of the cabinet for high-voltage switchgear reducer installation. It is suitable for precise positioning and efficient riveting operation during the riveting process of the cabinet end plate, solving the problems of inaccurate positioning and low efficiency of traditional manual riveting. Background Technology

[0002] In the manufacturing process of high-voltage switchgear, the riveting of the end plates of the high-voltage switchgear reducer mounting cabinet is one of the key processes. Traditional riveting methods rely primarily on manual operation, requiring operators to manually position the end plates before using tools to rivet them. However, manual positioning makes it difficult to guarantee the positional accuracy of the end plates during riveting, easily leading to positioning deviations. This results in the riveted end plates failing to meet assembly requirements, necessitating rework and increasing production costs and time. Furthermore, manual riveting is inefficient, physically demanding, and prolonged operation can further reduce riveting accuracy and efficiency due to fatigue, failing to meet the demands of large-scale high-voltage switchgear production. Therefore, there is an urgent need for auxiliary equipment capable of precise positioning and efficient riveting of end plates to address the problems associated with traditional manual riveting. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of inaccurate positioning and low efficiency in the traditional manual riveting of the cabinet end plates of high-voltage switch reducers. It provides an auxiliary device for riveting the cabinet end plates of high-voltage switches. By optimizing the overall structural support through a C-shaped frame and combining multi-component collaborative positioning and driving, it achieves accurate positioning and efficient riveting of the cabinet end plates, thereby improving production efficiency and riveting quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-voltage switch cabinet end plate riveting auxiliary device includes a C-shaped frame, a base, a lower base plate, a guide column, an upper pressure plate, a drive lifting cylinder, a rivet riveting clamping top rod, a positioning plate, a positioning groove, and a slot for the vertical bending edge of the processed plate to pass through and avoid. The C-shaped frame has a "C" shaped structure, including a horizontally set platform and a top beam vertically fixed to one side of the platform. The top beam is vertically distributed with the platform and is located directly above the subsequent upper pressure plate, providing stable installation support for driving the lifting cylinder. The base is bolted to the platform of the C-shaped frame, and the lower base plate is bolted to the top of the base. The base is used to elevate the lower base plate to facilitate the handling and operation of the processed parts. The guide post is provided with two posts, which are located at the four corners of the lower base plate and are symmetrically distributed. The lower ends of the two guide posts are welded and fixed to the lower base plate. The upper pressure plate has four through holes that are adapted to the guide posts. The upper pressure plate is movably sleeved on the two guide posts through the through holes and can move stably up and down along the axial direction of the guide posts to avoid deviation. The upper body of the drive lifting cylinder is fixed to the top crossbeam of the C-shaped frame by bolts. The lower drive end of the drive lifting cylinder is connected to the bottom of the upper pressure plate through a flange. When the drive lifting cylinder is working, it can drive the upper pressure plate to move up and down along the guide column, providing stable power for riveting and pressing. The positioning plate is fixedly installed on the top of the bottom plate by bolts and is located between two guide posts. The top of the positioning plate is integrally formed with a positioning groove, which is adapted to the positioning protrusion on the processing plate and is used to perform lateral positioning of the processing plate. The positioning plate is also provided with a slot for the vertical bending edge of the processing plate to pass through and avoid interference. The slot runs through the front and rear sides of the positioning plate to avoid interference between the positioning plate and the placement of the processing plate. The rivet clamping top rod is provided with four rods. All four rods are fixedly installed on the bottom of the upper pressure plate by threaded connection, and their positions correspond one-to-one with the positions of the rivets to be riveted on the processing plate. When the upper pressure plate moves down, the rivets can be precisely clamped to assist the riveting operation.

[0005] Compared with the prior art, the present invention has the following beneficial effects: Stable and reliable structure: The C-shaped frame provides overall support, and the driving lifting cylinder is fixed to the top crossbeam and the base is installed on the platform, forming a symmetrical and stable force-bearing structure, which avoids shaking during operation and ensures riveting accuracy; Precise and efficient positioning: The positioning groove cooperates with the positioning protrusion of the processing plate to form positioning, while avoiding the slot opening to facilitate the placement of the processing plate, effectively solving the problem of inaccurate traditional manual positioning; Easy and labor-saving operation: The lifting cylinder drives the upper pressure plate to move along the guide column through the flange, which drives the rivet riveting clamping top rod to automatically clamp the rivet, replacing manual operation, reducing labor intensity and improving riveting efficiency; Flexible assembly and adaptability: Each component is detachably connected by bolts, threads, etc. The number and position of guide columns, rivets, and clamping rods can be adjusted according to the specifications of the processed plates to adapt to the riveting requirements of different models of cabinet end plates.
