Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a rapid welding production device for automotive seat metal frames. Background Technology

[0002] The rapid welding production equipment for automotive seat metal frames is a device specifically designed for efficient and high-quality welding of automotive seat metal frames.

[0003] For example, the Chinese authorized patent (welding fixture) with publication number CN217913611U includes a support device, a pressure head device, a buffer device, and a connecting device. The buffer device includes a buffer connecting block, a buffer, and a buffer stop. The pressure head device and the connecting device are rotatably connected. The connecting device is fixed to the support device, the buffer connecting block is fixed to the connecting device and threadedly connected to the buffer, and the buffer stop is installed on the pressure head device at a position corresponding to the buffer. The buffer is used to buffer the force applied to the welding fixture by the pressure head device during its movement. This invention reduces the impact on the overall fixture during the welding fixture's operation, reduces damage to the fixture and its impact on product quality during welding production, shortens the replacement frequency of welding fixture components, increases the service life of the welding fixture, reduces the cost of using the welding fixture, and better ensures product quality.

[0004] However, most existing fixtures for welding automotive seat metal frames are fixed with fasteners, making replacement time-consuming, labor-intensive, and inconvenient; therefore, they do not meet current needs. In response, we have proposed a rapid welding production device for automotive seat metal frames. Utility Model Content

[0005] The purpose of this invention is to provide a rapid welding production device for automotive seat metal frames, in order to solve the problem mentioned in the background art that most of the existing automotive seat metal frame welding fixtures are fixed by fasteners, resulting in time-consuming and labor-intensive replacements that are inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid welding production device for automotive seat metal frames, comprising: a support frame, a first base provided on one side of the bottom end of the support frame, a second base provided on the other side of the bottom end of the support frame, a clamp provided on the upper end of the first base, a limiting end provided on the upper end of the second base, and a metal frame provided between the limiting end and the clamp.

[0007] Preferably, the clamp includes a vertical frame, a connecting frame is provided on one side of the vertical frame, a support frame is provided above the connecting frame, a fixing sleeve is provided on the other side of the vertical frame, and a locking seat is provided at the front end of the fixing sleeve.

[0008] Preferably, a locking pin is inserted inside the locking seat and moves along the locking seat. A locking pin is provided on one side surface of one end of the locking pin, a positioning part is provided at the lower end of the locking pin, and a mounting base plate is provided at the lower end of the positioning part.

[0009] Preferably, the positioning part includes a positioning plate, the upper surface of the positioning plate is provided with an unlocking groove, one side of the unlocking groove is provided with a locking groove, and a locking pin is switched between being inserted into the unlocking groove and the locking groove.

[0010] Preferably, the positioning part further includes a fixed base plate, and the fixed base plate is located on one side of the positioning plate, and a triangular plate is provided outside a right angle of the fixed base plate.

[0011] Preferably, the clamp further includes a limiting post, which is located at the upper end of the connecting frame. A mounting base is provided on the outer side of the bottom end of the limiting post. A through groove is provided on the upper surface of the support frame, and the mounting base is inserted into the through groove, with the limiting post passing through the through groove.

[0012] Preferably, both ends of the connecting frame are provided with fixing bolts, and one end of the fixing bolt passes through the connecting frame and is threadedly connected to the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a locking seat on one side of the vertical frame. The locking pin moves along the locking seat and inserts the locking pin into the locking groove. The locking pin connects the positioning part and the vertical frame to prevent separation. When it is necessary to disassemble and replace, the locking pin moves along the locking seat and inserts the locking pin into the unlocking groove. The solenoid valve located at the bottom of the positioning plate and corresponding to the unlocking groove is opened. Then the vertical frame is shaken. If it can shake, it means that it is unlocked. At this time, the vertical frame, support frame and connecting frame can be disassembled and replaced. This improves the convenience of replacement and the stability and firmness of locking. It solves the problem that most of the existing car seat metal frame welding clamps are fixed by fasteners, which makes replacement time-consuming, laborious and inconvenient.

[0015] (2) By setting a limiting post at the upper end of the connecting frame, inserting the mounting seat into the through groove, and the limiting post passing through the through groove, the connecting frame is fixed to the support frame by fixing bolts. The metal frame is placed between the limiting end and the clamp, and the limiting post of the limiting end and the clamp passes through the metal frame respectively. The limiting post contacts the inner wall of the metal frame, thereby limiting and fixing the metal frame, reducing the contact area, thus not hindering welding and improving welding stability.
