Technical Field

[0001] This utility model relates to the technical field of machining fixtures, and in particular to a welding fixture for traction seat frame assembly. Background Technology

[0002] The traction seat frame requires welding before further processing and manufacturing. Currently, both manual and gantry-type clamping assembly methods rely on traditional techniques requiring two operators, which significantly wastes labor costs and increases the workload of workers. Therefore, it is necessary to develop a new, semi-automatic traction seat frame assembly and welding fixture that can be operated by a single person to meet production needs. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the present invention provides a welding fixture for assembling a traction seat frame.

[0004] The present invention provides a welding fixture for a traction seat frame assembly, which adopts the following technical solution: A welding fixture for traction seat frame assembly includes a platform and a control panel. The platform is equipped with a positioning cylinder and an M-shaped plate positioning mechanism for fixing an M-shaped plate, a front and rear plate clamping mechanism for fixing the front or rear plate, an ear plate clamping mechanism for fixing the inner or outer ear, and a frame positioning mechanism for fixing the traction seat frame.

[0005] By adopting the above technical solution, a single person can place the parts to be assembled in the corresponding positions and control the positioning cylinder, M-shaped plate positioning mechanism, front and rear piece clamping mechanism, ear plate clamping mechanism and frame positioning mechanism through the operation control panel to achieve precise clamping and positioning of each part. A single person can perform spot welding and complete the assembly of the entire frame assembly. This tooling is simple and efficient to operate and the parts are accurately positioned.

[0006] Preferably, the M-type plate positioning mechanism includes a bushing mounting bracket hinged to one side of the platform, a bushing fixed on the bushing mounting bracket, a cylinder 1 vertically arranged on one side of the platform, the top end of the piston rod of the cylinder 1 being hinged to the tail end of the bushing mounting bracket, and the piston rod of the positioning cylinder slidingly passing through the bushing.

[0007] By adopting the above technical solution, the piston rod of the cylinder extends to drive the bushing mounting bracket to rotate, so that the bushing applies pressure to the M-shaped plate, and the piston rod of the positioning cylinder extends to insert into the bushing, thereby cooperating to fix the M-shaped plate, and the M-shaped plate is firmly fixed.

[0008] Preferably, the bushing mounting bracket has a first protrusion and a second protrusion at its head. The M-shaped plate positioning mechanism also includes a bushing positioning bracket on the other side of the platform and a second cylinder for vertically pushing the first protrusion. The top of the bushing positioning bracket has a slot, and the second protrusion can be detachably inserted into the slot.

[0009] By adopting the above technical solution, the second protrusion cooperates with the slot, which improves the accuracy of the bushing pressing position. The second cylinder cooperates with the lifting bushing mounting bracket, which facilitates the bushing to detach from the M-shaped plate.

[0010] Preferably, the front and rear piece clamping mechanism includes a U-shaped clamping plate, a stop, and a cylinder three installed on the top surface of the platform. The U-shaped clamping plate is set with its opening facing upward, and the stop and the cylinder three are respectively set on the left and right sides of the front piece or the rear piece.

[0011] By adopting the above technical solution, the U-shaped clamp initially fixes the front or rear piece, and the front or rear piece is clamped and fixed by the cooperation of the cylinder and the stop seat, thereby improving the stability of the front or rear piece.

The positioning seat and the cylinder four are fixedly installed on the platform, and the sliding seat is slidably connected to the platform. A push rod for pressing against the inner ear or outer ear is horizontally installed on the sliding seat. The push rod is slidably inserted through the positioning seat, and the piston rod of the positioning cylinder is slidably inserted through the positioning seat and the sliding seat.

[0013] By adopting the above technical solution, the cylinder four-wheel drive causes the sliding seat to move, the sliding seat drives the push rod, and the push rod cooperates with the M-shaped plate to squeeze and fix the inner ear or outer ear, thereby keeping the inner ear or outer ear stable.

[0014] Preferably, a stop block is fixedly connected to the top rod, the stop block is supported on the side of the sliding seat near the positioning seat, and a compression spring is sleeved on the top rod, the compression spring elastically supporting the stop block and the positioning seat.

[0015] By adopting the above technical solution, when the cylinder retracts, the compression spring elastically extends, causing the push rod to disengage from the inner or outer ear, which facilitates the subsequent removal of the traction seat frame.

[0016] Preferably, a slide rail is fixedly installed on the top surface of the platform, and the sliding seat is slidably installed on the slide rail.

[0017] By adopting the above technical solution, the sliding seat and the slide rail work together to improve the stability of the sliding seat during movement.

[0018] Preferably, the frame positioning mechanism includes a positioning hook, the bottom end of which is hinged to the platform. A cylinder five is installed on the side of the platform to drive the positioning hook to rotate and hook the front or rear piece. The piston rod of the cylinder five is connected to the positioning hook.

[0020] Preferably, the positioning hook is provided with a waist-shaped hole, and a U-shaped connecting plate is installed at the end of the piston rod of the cylinder. The U-shaped connecting plate is clamped on the positioning hook, and a connecting pin passing through the waist-shaped hole is installed between the two arms of the U-shaped connecting plate.

[0021] By adopting the above technical solution, the connecting pin can move within the oblong hole, allowing the piston rod of the cylinder to effectively cooperate with the positioning hook.

[0022] Preferably, it also includes a frame lifting mechanism, which includes a cylinder six vertically installed below the platform. A horizontally arranged crossbeam is installed at the top of the piston rod of the cylinder six. A push rod is vertically installed at the top of the crossbeam. The push rod slides through the platform, and a support plate for lifting the traction seat frame is installed at the top of the push rod.

[0023] By adopting the above technical solution, after welding is completed, the six-cylinder drive moves the crossbeam, push rod and support plate upward, and the support plate lifts the traction seat frame, making it easy for the staff to remove the traction seat frame.
