Description

Technical Field

[0001] This utility model relates to the field of stainless steel pump body production and processing technology, specifically to a stainless steel pump body welding auxiliary device. Background Technology

[0002] A stainless steel pump body refers to a pump component whose main structure (pump casing) is made of stainless steel. It is the core component of the pump, housing internal working parts (such as impellers, shafts, and seals), bearing fluid pressure, and guiding fluid flow along the designed path. The welding of the inlet and outlet flanges of the stainless steel pump body is a critical process that directly affects the pump's sealing performance, corrosion resistance, and service life.

[0003] Based on the above, the following problems were found: the pump casing and inlet / outlet flanges are usually eccentric structures. Ordinary welding robots can only handle regular workpieces and it is difficult to accurately perform circumferential welding on the inlet / outlet flanges. Manual welding is inefficient and inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a stainless steel pump body welding auxiliary device in order to achieve a more practical purpose. Utility Model Content

The positioning rod is located at the top of the center of the rotating seat.

[0007] By adopting the above technical solution, the electric turntable facilitates the provision of a rotational power source to drive the fixed component to rotate the pump body horizontally. The rotating base provides an installation foundation for the fixed component, allowing the electric turntable to drive its rotation. The positioning holes facilitate the positioning of the fixed component during installation. The fixing bolts allow for easy fixation of the fixed component to the top of the rotating base and enable replacement of the fixed component according to the pump body to be welded, facilitating pump body welding. The through holes allow for convenient fixing of the fixed component onto the rotating base using fixing bolts. The positioning blocks facilitate the positioning of the pump body to be welded, allowing the loading and unloading equipment to place the pump body on top of the fixed plate and preventing pump body slippage. The positioning rods pass through the pump body to position the inlet and outlet flanges, facilitating the rotation of the pump body driven by the rotating component. This enables external welding equipment to stably and accurately weld the pump body and inlet / outlet flanges, improving welding precision.

[0015] By adopting the above technical solution, the support block is set inside the pump body. When the sliding block slides towards the positioning block, the support block and the positioning block cooperate to clamp and fix the pump body, thereby achieving stable installation of the pump body on the top of the fixed plate.

[0016] Furthermore, a worm gear is rotatably connected inside the fixed disk, and a toothed column is fixedly installed at the bottom of the sliding block, the toothed column meshing with the worm gear.

[0017] By adopting the above technical solution, the worm gear is designed to facilitate the rotation of the worm gear and control the sliding block to slide along the guide groove.

[0018] Furthermore, a clamping motor is fixedly installed in the middle of the fixed disk, and the output end of the clamping motor is fixedly connected to the worm gear.
