[0001] This utility model relates to a welding fixture for pipe fittings, specifically a support dry limiting mechanism and a support welding clamping device. Background Technology

[0002] Pipe supports are mostly formed by bending or welding together multiple formed parts, such as Figure 10 The bracket shown requires the welding of multiple components during processing, such as... Figure 11 As shown, the support has three main components: a horizontally arranged support trunk, a vertically arranged column, and auxiliary supports between the column and the trunk.

[0003] During the welding process, these three parts need to be clamped and positioned to facilitate subsequent welding. When clamping the support frame, the support frame is placed at an angle, which makes it easy to slip and difficult to position. Furthermore, the entire support frame needs to be quickly disassembled after welding is completed. Utility Model Content

Detailed Implementation

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0032] As described in the background section, pipe supports are mostly formed by bending or welding together multiple formed components, such as... Figure 10 The bracket shown requires the welding of multiple components during processing, such as... Figure 11 As shown, the support has three main components: a horizontally arranged support trunk, a vertically arranged column, and auxiliary supports between the column and the trunk.

[0033] During the welding process, these three parts need to be clamped and positioned to facilitate subsequent welding. When clamping the support frame, the support frame is placed at an angle, which makes it easy to slip and difficult to position. Furthermore, the entire support frame needs to be quickly disassembled after welding is completed.

[0034] For the reasons mentioned above, this embodiment provides a support dry limiting mechanism, such as... Figures 4-7 As shown, the support frame limiting mechanism includes a limiting working surface, a positioning block 204 and a fixing block 202. The fixing block is fixedly installed on the limiting working surface. The positioning block is installed on the front of the fixing block through a guide rod 203. The guide rod passes through the positioning block and a positioning groove 205 is provided on the positioning block. The positioning groove is adapted to the end of the support frame.

[0035] An elastic element 206 (such as a spring) is installed between the positioning block and the fixing block and is fitted onto the guide rod.

[0036] The aforementioned technical features enable rapid positioning of the support frame via a slider-type positioning block, and allow for quick disassembly after welding. During use, the positioning block slides on the working surface, changing its position. When positioning is required, a spring-loaded component pushes the positioning block to the designated position, aligning the positioning groove and providing a positioning point for the support frame. The spring force provided by this component is greater than the backward or downward force of the support frame, preventing misalignment of the positioning point. For disassembly, the operator simply pushes the positioning block in the opposite direction of the spring force to release the positioning block's constraint and positioning of the support frame.

[0037] To ensure the positioning block reaches a designated position under the action of the elastic element, in one embodiment, a positioning block limiting member acting on the positioning block is installed on the limiting working surface or guide rod. The positioning block limiting member provides a positioning point for the positioning block, facilitating the positioning of the support frame.

[0038] For example, in one embodiment, the guide rod 203 is a screw, and the positioning block is a nut installed on the screw. Since the guide rod passes through the positioning block, the positioning block can be positioned by the nut. Furthermore, the position of the nut is adjustable through the cooperation between the nut and the screw, making it suitable for positioning various specifications or models of brackets. The positioning and limiting block can also be a protrusion fixed to the working surface.

[0039] To ensure smooth movement of the positioning block and provide accurate resetting, in one embodiment, a dovetail-shaped track 207 adapted to the positioning block is fixedly installed on the limiting working surface. The track allows the positioning block to move smoothly while accurately resetting, preventing deviation. Because the guide rod is a screw, the screw cannot fully serve as a guide for the positioning block's movement. Guiding with a screw can easily affect or damage the threads during the positioning block's sliding process, making subsequent nut installation or adjustment inconvenient.

[0040] In order to achieve such Figure 11 In another embodiment, the clamping of the three components of the bracket 600 shown is provided, such as a bracket welding clamping device. Figures 1-3 As shown, the bracket welding clamping device includes a workbench 100, a column limiting mechanism, and a bracket dry limiting mechanism 200 as described in the above embodiment. The column limiting mechanism is mounted on the workbench 100 via a column mounting platform 500. The bracket dry limiting mechanism is located on one side of the column limiting mechanism and is mounted on the workbench via a bracket dry mounting platform 201. The limiting working surface is the upper plane of the bracket dry mounting platform.

[0041] For example, such as Figure 8 and Figure 9 As shown, the column limiting mechanism includes a column limiting part 400 and column accessory limiting parts 300 located on both sides;

[0042] The column limiting part 400 includes a lower column limiting part 405, a pressure arm 402, a column pressure block 404, and a telescopic cylinder 401. The cylinder body of the telescopic cylinder is fixedly installed on the column mounting platform 500. The telescopic rod of the telescopic cylinder 401 is rotatably connected to the pressure arm 402 through a pin. The pressure arm 402 is rotatably installed on the pressure arm mounting block 403. The pressure arm mounting block 403 is fixedly installed on the column mounting platform 500. The column pressure block 404 is fixedly installed on the pressure arm 402. The lower column limiting part 405 is fixedly installed on the column mounting platform 500.

[0043] For example, the column accessory limiting part 300 includes a quick clamp 302, an accessory support block 303 and an accessory pressing block. The quick clamp is installed on the column mounting platform through a quick clamp bracket 301, the accessory pressing block is installed at the end of the quick clamp, and the accessory support block is fixedly installed on the column mounting platform.

[0044] For example, a bracket auxiliary support block is installed between the two column accessory limiting parts.

[0045] The aforementioned technical features enable the bracket to be clamped, facilitating subsequent welding processes. In use, the column is first placed at the lower limit position, then the column is pressed down by the column clamping block, and the bracket body is arranged laterally, with one end of the bracket body contacting the column and the other end placed in the positioning groove of the positioning block. Then, the auxiliary support is installed between the column and the bracket body, wherein the connecting ear of the auxiliary support is installed on the accessory support block. Then, the accessory clamping block is pushed by the block clamp to press the accessory clamping block onto the connecting ear, thereby achieving the clamping of the entire bracket for subsequent welding.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
