Description

Technical Field

[0001] This utility model relates to the field of vehicle body frame assembly platform, specifically an assembly platform for vehicle body frame assembly. Background Technology

[0002] The vehicle body frame is the basic supporting structure of an automobile, consisting of core load-bearing components such as longitudinal beams, cross beams, and pillars. It bears the load of the entire vehicle, ensures structural strength and occupant safety, and achieves lightweighting and collision protection through optimized design. The vehicle body frame assembly platform is a large-scale specialized process equipment used to precisely position, clamp, and weld the six major components of the vehicle body (front bulkhead, rear bulkhead, left and right side bulkheads, roof, and chassis frame assembly) into a hexahedral structure. It is usually used in conjunction with industrial robots.

[0003] Based on existing assembly tables for vehicle body frames, it was found that the welding of the vehicle body frame is carried out by robots on the assembly table. However, the assembly table itself has a simple structure and low adjustability. In particular, the driving of the assembly table is usually transmitted through the ground drive wheels in the workshop. However, the assembly table is difficult to move when it is detached from the ground drive wheels. Based on this, this utility model designs an assembly table for vehicle body frames to solve the above problems. Utility Model Content

[0032] Support socket 201: vertically welded to the four corners of the assembly table 1, with a rectangular sliding groove inside;

[0033] Support plate 202: Inserted into the groove of support socket 201, with support frame 203 connected at the bottom;

[0041] The working principle of this utility model is as follows: The assembly table for the body frame assembly achieves dynamic adaptation and multi-scenario movement through the modularly designed adjustment mechanism 2 and conveying mechanism 3. The adjustment mechanism 2 consists of a support socket 201, a support plate 202, and an adjusting screw 205. When the operator rotates the adjusting screw 205, the support plate 202 slides linearly within the support socket 201 through the transmission of the threaded seat 204, driving the assembly table body 1 to rise and fall. Four sets of symmetrically distributed support units, together with the reinforcing steel frame 207, ensure stability. The placement tray 208 adjusts its height synchronously to maintain operational convenience. The conveying mechanism 3 includes a drive motor 302 that drives three sets of transmission wheels 304 and drive wheels 307 through a transmission belt 303. The limiting slide rail 308 at the bottom of the bearing plate 206 achieves precise conveying on the production line. When detached from the production line, the universal wheels 310 at the bottom of the support seat 309 enable free manual movement. The two systems are mechanically linked through the bearing plate 206, ultimately achieving a triple functional integration of stepless adjustment of assembly height, synchronous conveying on the production line, and offline autonomous displacement.
