[0027] Working principle of this utility model:
[0028] The roller support assembly welding fixture in this device mainly consists of several parts, including a crossbeam system 1, a slide table system 2, a centering module system 3, and a clamping system 4.
[0029] During operation, the crossbeam system 1 serves as the support, the L-shaped support 12 serves as the support connecting the positioner and the tooling, and the linear slide rail slider 13 serves as the guide and weighing mechanism of the slide table system. The workpiece 5 is placed on the clamping system 4, and the cylinder on the frame serves as the clamping device. After the workpiece is clamped, the cylinder has a self-locking function to prevent air leakage from the air pipe and causing the workpiece to fall.

The linear slide rail slider and the positioning pin are used in conjunction to meet the workpiece requirements.
[0030] In conjunction with the upper slide system 2, the motor within the system drives the gears along the rack, adjusting the slide distance to meet usage requirements. The unpowered rollers support the workpiece, facilitating its axial movement. This allows for efficient welding operations.
