When the clamp needs to be adjusted or replaced, the operator may face great difficulties, thereby reducing work efficiency. Utility Model Content

[0005] In response to the problems mentioned in the background technology, the purpose of the present utility model is to provide a tooling fixture for welding automobile seats to solve the problem that the placement table cannot be disassembled when not in use, which occupies a large space and reduces the space utilization rate in the workshop or factory, and when the fixture needs to be adjusted or replaced, the operator may face great difficulties, thereby reducing work efficiency.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A fixture for welding a car seat comprises a base, an upper end of the base is provided with a receiving slot, a rotating disk is rotatably connected to the receiving slot, a rotating assembly is installed inside the receiving slot, an upper end of the rotating disk is fixedly connected to an electric push rod, a telescopic end of the electric push rod is movably connected to a mounting seat, a bottom end of the mounting seat is fixedly connected to a connecting block, a fixing assembly is symmetrically installed inside the connecting block, an upper end of the mounting seat is symmetrically slidably connected to a placement seat, connecting plates are symmetrically provided at both ends of the placement seat, a clamping assembly is directly installed on the connecting plate and the placement seat, one end of the connecting plate close to the placement seat is fixedly connected to a connecting rod, the other end of the connecting rod extends into the placement seat and is fixedly connected to a splint, and the other end of the splint is glued to a non-slip pad;

[0008] The locking block is fixedly provided with a locking plate, and one end of the locking plate is connected to the locking plate by a locking mechanism.

[0009] As an optimal technical solution, the rotating assembly includes a driving motor, a driving gear, a connecting shaft and a driven gear. The driving motor is installed at the bottom end of the accommodating groove, and the outer wall of the output end of the driving motor is fixedly connected to the driving gear. The bottom end of the accommodating groove is rotatably connected to the connecting shaft through a bearing, and the outer wall of the connecting shaft is fixedly connected to the driven gear. The driven gear and the driving gear are meshed with each other. An annular slide groove is provided inside the accommodating groove, and an annular slider is fixedly connected to the outer wall of the rotating disk. The curvature of the annular slide groove matches that of the annular slider. The annular slide groove and the annular slider are slidably connected, which enables the welding gun to easily reach various parts of the workpiece that need to be welded without moving the entire workpiece, thereby greatly reducing the time and labor cost of adjusting the position of the workpiece.

[0010] As an optimal technical solution, the clamping assembly includes a fixed seat, a first limiting column, a second limiting column and a tension spring. The opposite ends of the connecting plate and the placing seat are symmetrically fixedly connected with the fixed seat. One end of the placing seat is fixedly connected to the first limiting column. The second limiting column is slidably connected inside the first limiting column. The other end of the second limiting column is fixedly connected to the end of the fixed seat fixedly connected to one end of the connecting plate. Tension springs are sleeved on the outside of the first limiting column and the second limiting column. The head and tail ends of the tension springs are respectively fixedly connected to the opposite ends of the fixed seat, which can simplify the operation process of the tooling fixture and reduce the difficulty and complexity of the operation.

[0011] As an optimal technical solution, T-shaped slots are symmetrically opened on the upper end of the mounting seat, and T-shaped blocks are symmetrically fixedly connected to the bottom end of the placement seat. The T-shaped blocks and T-shaped slots are slidably connected, which can make the welding surface fitting process faster and more accurate, reducing adjustment time and waiting time.

[0012] In summary, the present invention has the following beneficial effects:

[0013] First, in the present invention, the mounting seat is combined with the telescopic end of the electric push rod, so that the connecting block is inserted into the connecting groove. During the insertion process, the extrusion force applies pressure to the inclined surface of the bottom end of the locking block, so that the locking block drives the movable plate to compress the reset spring, and the locking block retracts into the cavity. Then, when the locking block moves to the locking groove, the reset spring is reset, and the movable plate rebounds to drive the locking block to pop out. The locking block and the locking groove are clamped and fixed to complete the installation of the mounting seat. This allows operators to quickly adjust or replace the fixture according to production needs, greatly improving the flexibility of operation. In addition, the mounting seat can be disassembled and stored in a designated area, effectively saving production space.

[0014] Second, in the present invention, the driving motor is started to control the driving gear to rotate, the driving gear drives the driven gear to rotate, and at the same time the driven gear drives the connecting shaft to rotate, the connecting shaft drives the rotating disk to rotate inside the rotating groove, and at the same time the annular slider slides inside the annular slide groove. When the rotating disk rotates, it drives the upper electric push rod and the mounting seat and the seat workpiece to rotate, so that the welding gun can easily reach various parts of the workpiece that need to be welded without moving the entire workpiece, thereby greatly reducing the time and labor cost of adjusting the workpiece position, and can ensure that the workpiece is in the best welding position during welding, making the welding operation more accurate and stable.
