Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, and more specifically, to a component welding anti-deformation tooling. Background Art

[0002] During the processing of parts, welding operations are often required. During welding, the parts need to be clamped and fixed to facilitate welding.

[0003] After searching, the existing patent (publication number: CN212977272U) discloses a fixture for welding arc-shaped parts, including a base, a first mounting groove, a second mounting groove and two first slide grooves are provided on the base, and a second slide groove is provided on the inner side wall of the second mounting groove. Two baffles are fixedly installed on the top of the base, and the part to be welded is placed on the base, and the part to be welded is pressed against the two baffles. A clamping mechanism is provided in each of the two first slide grooves, and the two clamping mechanisms are pressed against the ends of the part to be welded. A pushing mechanism is provided in the first mounting groove, and the pushing mechanism is fixedly connected to the side walls of the two clamping mechanisms. A clamping mechanism is provided in the second mounting groove, and the side walls of the clamping mechanism are pressed against the side walls of the part to be welded. The structural design of this utility model is reasonable, and it can limit and clamp arc-shaped parts with special shapes, so that they will not easily move during the welding process, ensuring the normal progress of the welding work. In the process of realizing this utility model, the inventor found that the existing technology has the following problems:

[0004] Existing fixtures cause the metal to expand thermally when the welded parts are heated to a high temperature, and then contract after cooling. The shrinkage of the weld and the surrounding area causes deformation of the overall structure. The stress and temperature changes during welding make it difficult for workers to control the dimensions of subsequent components, which can easily lead to improper assembly or poor docking of components. Workers need to make multiple corrections through manual or mechanical means, resulting in a large amount of rework, which invisibly increases labor costs and reduces production efficiency. The deformation needs to be corrected on machine tools, causing costs to increase exponentially. In addition, the fixtures will be damaged by factors such as high temperature and deformation during the welding process during long-term use, requiring regular maintenance and correction, thereby increasing overall production costs.

[0005] Therefore, in order to solve the above problems, a component welding anti-deformation tool is proposed. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0032] As attached Figures 1 to 10 The illustrated assembly welding anti-deformation tool comprises a longitudinal square tube 1, an upper mounting plate 4, a lower mounting plate 5, a weldment body 6, and a fixing pile 10. A transverse square tube 2 is provided on one side of the lower end of the longitudinal square tube 1. A connecting thick plate 3 is installed between the longitudinal square tube 1 and the transverse square tube 2. The upper mounting plate 4 is provided on the left side of the upper end of the longitudinal square tube 1, and the lower mounting plate 5 is provided on the left side of the transverse square tube 2. The weldment body 6 is installed above the connecting thick plate 3.

[0033] A first positioning locking pin 7 is installed in the inner cavity of one end of the weldment body 6, and a second positioning locking pin 8 is installed in the inner cavity of the other end of the weldment body 6. The two ends of the weldment body 6 are respectively abutted on the same side of the upper mounting plate 4 and the lower mounting plate 5. Nuts 9 are installed on the outer surfaces of the first positioning locking pin 7 and the second positioning locking pin 8. Several groups of nuts 9 are provided. A fixing pile 10 is welded to the left side of the lower mounting plate 5. Adjustment holes 11 are opened in the inner cavity at the four corners of the fixing pile 10, and bolts 12 are installed in the inner cavity of the adjusting hole 11.

[0034] Among them: when the weldment body 6 needs to be fixed for processing, the longitudinal square tube 1, the transverse square tube 2 and the connecting thick plate 3 together form a supporting frame, thereby providing a stable foundation, so that the weldment body 6 is not easily deformed or displaced during processing, the upper mounting plate 4 and the lower mounting plate 5 are respectively located at one end of the longitudinal square tube 1 and the transverse square tube 2, the first positioning locking pin 7 and the second positioning locking pin 8 respectively install the two ends of the weldment body 6 on the upper mounting plate 4 and the lower mounting plate 5, and lock them with nuts 9, thereby ensuring that the weldment body 6 is firmly installed in the predetermined position during processing, and bolts 12 are installed in the adjustment holes 11 at the four corners of the fixing pile 10. The fixing pile 10 abuts against the weldment body 6 through the bolts 12, thereby allowing the operator to accurately adjust the support when installing the weldment body 6. By rotating the bolt 12, the protruding length of the bolt 12 can be adjusted, thereby achieving more precise positioning and support for the weldment body 6. Example 2

[0035] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 10 As shown, see the following description for details:

[0036] As a preferred embodiment, the two ends of the weldment body 6 respectively abut against one side of the upper mounting plate 4 and the lower mounting plate 5, and the shape of the weldment body 6 is arc-shaped; further, a good contact surface is formed between the arc-shaped weldment body 6 and the upper mounting plate 4 and the lower mounting plate 5, abutting against each other and providing stable support.

[0037] As a preferred embodiment, one end of the first positioning locking pin 7 passes through the inner cavity of the weldment body 6 and the lower end mounting plate 5 in sequence, and the first positioning locking pin 7 is engaged with the nut 9; further, the first positioning locking pin 7 ensures the fastening relationship between the weldment body 6 and the lower end mounting plate 5 through the engagement connection with the nut 9, effectively fixing the position of the weldment body 6 and avoiding displacement caused by the action of force during operation or use.

[0038] As a preferred embodiment, one end of the second positioning locking pin 8 passes through the inner cavity of the weldment body 6 and the upper end mounting plate 4 in sequence, and the second positioning locking pin 8 is engaged and connected with the nut 9; further, the engagement of the second positioning locking pin 8 and the nut 9 ensures the tightness of the weldment body 6 and the upper end mounting plate 4.

[0039] As a preferred embodiment, thick ribs 13 are provided at both ends of the upper mounting plate 4 and the longitudinal square tube 1, and thick ribs 13 are provided at the connection between the lower mounting plate 5 and the two ends of the transverse square tube 2; further, the thick ribs 13 improve the strength of the connection between the upper mounting plate 4 and the longitudinal square tube 1, and can effectively withstand greater bending moments and shear forces, thereby ensuring the reliability of the overall structure under heavy load conditions.

[0040] As a preferred embodiment, the bolts 12 are engaged with the nuts 9 through the adjustment holes 11, and one end of each of the four groups of bolts 12 abuts against one side of the fixing pile 10; further, by rotating the bolts 12 in the adjustment holes 11 of the fixing pile 10, the bolts 12 slowly move to abut the surface of one end of the weldment body 6, thereby providing a firm support, making the weldment body 6 more stable when bearing loads, and reducing displacement or loosening caused by vibration or external force.

[0041] The working process of the present invention is as follows: first, when the weldment body 6 needs to be fixed, the longitudinal square tube 1, the transverse square tube 2 and the connecting thick plate 3 together form a supporting frame, and the longitudinal square tube 1 and the transverse square tube 2 have a lower mounting plate 5 and an upper mounting plate 4 at the ends away from each other, respectively. The two ends of the weldment body 6 are respectively mounted on the same side of the upper mounting plate 4 and the lower mounting plate 5 through the first positioning locking pin 7 and the second positioning locking pin 8, and are engaged and connected by nuts 9 to lock it. The fixing pile 10 on one side of the lower mounting plate 5 rotates the bolt 12 in the adjustment hole 11 and slowly abuts against the end where the weldment body 6 is connected to the lower mounting plate 5, thereby supporting it. The thick ribbed plate 13 increases the strength of the connection between the upper mounting plate 4 and the longitudinal square tube 1 and the lower mounting plate 5 and the transverse square tube 2, respectively, to provide further support strength. The above is the working principle of this component welding anti-deformation tooling.
