A kind of s pipe welding tool

Abstract

The invention provides an S pipe welding tool. The S pipe welding tool comprises a welding base, a spline shaft positioning seat, a cutting ring inner sleeve positioning mechanism, an S pipe body supporting adjusting seat, an S pipe body supporting seat and an outlet sleeve positioning mechanism, wherein the spindle shaft positioning seat comprises a spline shaft fixing sleeve; the cutting ring inner sleeve positioning mechanism comprises a three-jaw chuck; the outlet sleeve positioning mechanism comprises an outlet sleeve positioning sleeve; the abovementioned mechanisms are correspondingly used for positioning a spindle shaft, a cutting ring inner sleeve and an outlet sleeve; an S pipe body is positioned through the S pipe body supporting adjusting seat and the S pipe body supporting seat; the spindle shaft, the cutting ring inner sleeve, the S pipe body and the outlet sleeve are correspondingly subjected to spot welding through a welding machine after being positioned and are checked until the sizes are in line with a drawing, then each part is firmly welded, and thus the S pipe welding is finished. According to the S pipe welding tool, a matched spline shaft fixing sleeve and amatched outlet sleeve positioning sleeve are simply used through replacement to enable the S pipe welding tool to be applicable to S pipes with various sizes; and moreover, the S pipe welding tool can perform positioning more accurately, so that the S pipes are accurately, quickly and efficiently welded.

Description

technical field [0001] The present application relates to the field of concrete pumping mechanical equipment manufacturing, in particular to an S-pipe welding tool. Background technique [0002] Concrete delivery pump is a special equipment for transporting concrete to various construction sites through a pumping system for on-site concrete pouring. Because of its advantages of flexibility, convenience and high efficiency, it has become an important concrete delivery equipment for building high-rise buildings; the pump The delivery system is the core working mechanism of the concrete delivery pump, including S-valve and cartridge valve pumping systems. The S-valve pumping system has become the preferred structure of most concrete pumps due to its good sealing performance and high delivery pressure. [0003] The S tube is the core component of the S valve pumping system. figure 1 is a schematic structural diagram of a typical S tube, such as figure 1 As mentioned above, th...

Problems solved by technology

[0004] The existing welding tooling uses pressure plates, adjusting bolts, etc. to position and combine the S tube components together for welding. Since the S tubes have different sizes, it is necessary to make multiple sets of welding tools of different specifications to match the size of the S tubes. That is to say, the existing welding tool is a special structure with a single size, which cannot be used universally for S tubes of different sizes. Therefore, the operator needs to switch between different welding tools during welding, and needs to perform repeated positioning and adjustment according to the size of the S tube , which not only wastes man-hours but also reduces the accuracy of S tube size
