Positioning jig of hole system welding platform

Abstract

The present invention relates to a positioning jig of a hole system welding platform, which comprises more than one positioning support rod, the positioning support rod is suitable for passing througha positioning hole of the hole system welding platform and extending positioning along two sides of the positioning hole, more than one of the positioning support rod is used as support for forming at least one positioning support surface or clamping surface. The positioning support surface or support platform formed by building the support bar can replace a square-box function in prior art. Thesupport rod can extend along two sides of the positioning hole, thereby, a height of the formed support surface or support platform can be adjusted. Compared with the clamping by utilizing an insert type clamp in prior art, the formed support surface is more stable and accurate by selecting more than one positioning support bar, which realizes the support function no existed in the insert type clamp.

Description

technical field [0001] The invention relates to a welding positioning fixture, which is especially suitable for positioning and clamping workpieces on a welding workbench combined with holes or slots. Background technique [0002] The flexible welding workbench combined with holes or slot holes has many evenly arranged positioning holes on its table, and these positioning holes are used to locate or connect the corresponding fixtures or auxiliary tools, so as to realize the reasonable positioning of the workpieces welded on the platform. Positioning and clamping: There are mainly two positioning methods utilizing positioning holes in the prior art, and a commonly used one is the positioning method disclosed in the invention application of CN101053933A and the patent No. US5,676,359. Such positioning methods mostly use the superposition and combination of welding square boxes, right-angle positioning parts, connectors, etc. to complete the spatial positioning of the welded wo...

[0002] The flexible welding workbench combined with holes or slot holes has many evenly arranged positioning holes on its table, and these positioning holes are used to locate or connect the corresponding fixtures or auxiliary tools, so as to realize the reasonable positioning of the workpieces welded on the platform. Positioning and clamping: There are mainly two positioning methods utilizing positioning holes in the prior art, and a commonly used one is the positioning method disclosed in the invention application of CN101053933A and the patent No. US5,676,359. Such positioning methods mostly use the superposition and combination of welding square boxes, right-angle positioning parts, connectors, etc. to complete the spatial positioning of the welded workpieces. This positioning method can usually complete the positioning better, but its construction requirements are high. It takes up a lot of space and takes time to build. The most important thing is that the selected positioning parts are expensive, which is also the biggest obstacle for the current flexible welding workbench to be fully popularized; The German patent document DE10011490A1 and the U.S. patent No. US5,318,284 disclose the positioning form of using plug-in clamps to locate the welding workpiece. The feature of this type of positioning form is that it is easy to adjust, and the disadvantage is that it is limited to clamping and cannot The workpiece is supported from below, and due to the limitation of its structure, the plunger will deviate in the vertical direction when clamping with force, thus affecting the accuracy of positioning
