It can be divided into cutting and pressure processing according to the difference in processing methods. When a welding platform performs welding machining, it needs to clamp and position the workpiece, which requires a workpiece clamping and fixing structure that works with the welding platform.

[0003] The existing Chinese patent CN217224006U, disclosed on August 19, 2022, is a clamping device for arc welding workpieces, belonging to the field of arc welding technology. It includes a worktable and a support plate. The support plate is fixedly installed on one side of the worktable.

The slide groove A is fixedly installed on one side of the upper part of the worktable, and the placement plate A is installed on the upper part of the slide groove A through the slider.

[0004] However, when the above-mentioned device clamps the workpiece, it fixes it through the clamping mechanism and the fixing mechanism, and uses the plane of the clamping plate A for clamping. When fixing a smooth round rod workpiece, the overall fixation is not very stable.

[0005] Therefore, we propose a novel workpiece clamping and fixing structure that mates with a welding platform to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a workpiece clamping and fixing structure that works in conjunction with a welding platform. This solves the problem that when the above-mentioned devices clamp workpieces, the overall fixing is not very stable when using the plane of the clamping plate A for clamping, as the clamping mechanism and fixing mechanism are used for fixing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a workpiece clamping and fixing structure that cooperates with a welding platform, comprising: A platform mounting base, which is mounted on the welding platform by screws; A magnetic telescopic mechanism is installed inside the middle of the platform mounting base by screws. A pipe fitting limiting and clamping mechanism is installed on the upper end of the platform fixing base by screws; Two side abutment mechanisms are symmetrically installed on both sides of the upper end of the pipe fitting limiting clamping mechanism.

[0008] Preferably, the platform mounting base includes a screw mounting plate, which is mounted on the welding platform by screws. A hollow sleeve is fixed to the middle of the upper end of the screw mounting plate, and a limiting cavity is formed on the inner side of the hollow sleeve.

[0009] Preferably, the magnetic telescopic mechanism includes a first electric telescopic cylinder, which is mounted on the upper middle of the screw mounting plate by screws and located in the middle of the limiting sleeve cavity. The telescopic rod end of the first electric telescopic cylinder is mounted with a movable disc by screws, and a strong magnetic disc is fixed to the inner side of the upper end of the movable disc.

[0010] Preferably, the pipe fitting limiting clamping mechanism includes two adjusting clamping components and a workpiece limiting sleeve, wherein the adjusting clamping components are movably installed on the inner sides of both ends of the workpiece limiting sleeve.

[0011] Preferably, the adjusting clamping assembly includes an arc-shaped clamping plate, with a rubber pad adhered and fixed to the inner end of the arc-shaped clamping plate, an I-shaped turntable rotatably mounted on the inner side of the outer end of the arc-shaped clamping plate, an adjusting rotating rod fixed to the outer end of the I-shaped turntable, the adjusting rotating rod being threadedly connected to the workpiece limiting sleeve, and two positioning sleeves symmetrically fixed to both sides of the adjusting rotating rod on the arc-shaped clamping plate.

[0012] Preferably, the two positioning rods are correspondingly sleeved in the holes of the workpiece limiting sleeve.

A screw sleeve is fixedly connected to the inner side of the upper end of the L-shaped bracket, and a rotating screw is threadedly connected to the inner side of the screw sleeve. An abutment chuck is fixedly connected to the inner end of the rotating screw.

[0014] Preferably, the tops of the movable disk and the powerful magnet disk are aligned.

[0016] 2. This utility model can clamp and position a planar workpiece by setting a side abutment mechanism. The rotating screw of the side abutment mechanism can rotate in the screw sleeve, so it can move inward and outward by rotating in the forward and reverse directions. Rotating the screw can change the position of the abutment chuck for abutment.

[0024] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here.

Adjustable clamping components are movably installed on the inner sides of both ends of the workpiece limiting sleeve 1, and the workpiece inside the workpiece limiting sleeve 1 can be effectively clamped and positioned by the adjustable clamping components.
