Description

Technical Field

[0001] This utility model relates to the field of workpiece welding fixture technology, specifically to a multi-purpose anti-deformation process device for welding. Background Technology

[0002] In the field of construction machinery manufacturing, lightweight structural components have become an important development trend. To meet the demands of energy conservation, emission reduction, and improved equipment mobility, modern construction machinery widely uses thin-plate materials to manufacture major structural components. However, thin-plate materials face severe deformation problems during the welding process. Due to the uneven heat input during welding, thin-plate parts are prone to significant warping and shrinkage deformation after welding. These deformations not only affect the appearance quality of the product but also lead to serious assembly interference problems, impacting the overall performance and reliability of the machine.

[0003] Currently, the industry primarily uses manual adjustment to correct welding deformation. This method is not only inefficient but also heavily reliant on the experience and skill level of the operators. In actual production, multiple adjustments are often required to meet assembly requirements, significantly increasing production time and labor costs, and potentially leading to material fatigue and performance degradation. Furthermore, due to the varying structural characteristics and welding processes of different products, existing fixed anti-deformation tooling often has limited applicability and struggles to meet the demands of multi-variety, small-batch production. This situation severely restricts further improvements in production efficiency and product quality. Therefore, there is an urgent need for a versatile and flexible anti-deformation process device to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a multi-purpose anti-deformation process device for welding.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a multi-purpose anti-deformation process device for welding, comprising:

[0006] The support tube has its two ends sealed by gaskets. The upper part of the support tube is symmetrically provided with guide threaded tubes on both sides. The guide threaded tubes are internally threaded with a manual threaded rod. The upper part of the manual threaded rod is provided with a manual tightening head, and the bottom of the manual threaded rod is provided with a detachable tightening block.

[0007] As a preferred embodiment of this application, the bottom of the support tube is provided with a fixing seat, the fixing seat is provided with a fixing hole for fixing the device to the surface of the structural component, the fixing seat is provided with a locking opening, the support tube is locked in the locking opening, the fixing seat is connected to a connecting seat by bolts, and the bottom of the connecting seat is provided with a pressing port for pressing the support tube.

[0008] As a preferred embodiment of this application, the two ends of the support tube are also equipped with limiters via the manual threaded rod, the limiters being used to counteract lateral deformation generated during the welding process.

[0009] As a preferred embodiment of this application, the limiter includes a U-shaped mounting part, which is nested into the end of the support tube through a U-shaped fitting opening. The U-shaped mounting part is provided with a through hole for the manual threaded rod to pass through, and the manual tightening head presses the U-shaped mounting part onto the support tube.

[0010] As a preferred embodiment of this application, the end of the U-shaped mounting portion away from the support tube is provided with a tensioning screw, and a top rod sleeve is threaded onto the tensioning screw.

[0011] As a preferred embodiment of this application, an L-shaped frame is provided on the side of the U-shaped mounting part away from the support tube, and a U-shaped groove is formed between the L-shaped frame and the U-shaped mounting part. A screw and a fixing bolt are threaded to both sides of the U-shaped groove, respectively.

[0012] Compared with the prior art, this application has the following significant advantages:

[0013] First, this application achieves excellent versatility and adaptability through modular design. The device adopts an adjustable structural design, which can be flexibly adjusted according to the structural characteristics and welding deformation patterns of different products. By changing the configuration of different specifications of clamping blocks and adjusting the limit switches, the same device can be applied to multiple product models, greatly improving equipment utilization and economy. This design reduces tooling manufacturing costs and simplifies the complexity of tooling management on the production site.

[0014] Secondly, this application provides a precise and controllable anti-deformation adjustment capability. The device achieves fine-tuning through a threaded transmission mechanism, which can accurately set the anti-deformation amount based on the predicted value of welding deformation, thereby applying the deformation in the opposite direction in advance before welding, effectively counteracting the deformation generated during welding. This proactive, preventative deformation control method is not only more effective than post-correction methods, but also avoids secondary damage to the workpiece caused by correction operations.

[0015] Finally, this application significantly improves production efficiency and product quality. By using this device, the deformation of welded structural components is greatly reduced, decreasing the workload of subsequent shaping operations and shortening the production cycle. Simultaneously, due to effective deformation control, the dimensional accuracy and assembly quality of the workpieces are significantly improved, reducing rework and scrap losses caused by assembly interference. This device has a simple structure and is easy to operate, suitable for both mass production and small-batch single-piece production, and has significant potential for widespread application.

[0029] The support tube 1 has its two ends sealed by gaskets 6, which prevent impurities from entering the tube and enhance the strength of the ends. Symmetrically arranged guide threaded tubes 5 are provided on both sides of the upper part of the support tube 1. A manual threaded rod 3 is internally threaded into each guide threaded tube 5. The manual threaded rod 3 has a manual tightening head at its upper part and a removable tightening block 4 at its bottom. The tightening block 4 can be replaced according to the surface shape of the workpiece to increase the contact area and improve the anti-slip effect.

[0030] In this embodiment, the bottom of the support tube 1 is provided with a fixing seat 7. The fixing seat 7 has fixing holes for fixing the device to the surface of the structural component, and the fixing seat 7 can be fastened to the workpiece by bolts. The fixing seat 7 has a locking port, in which the support tube 1 is locked. A connecting seat 2 is connected to the fixing seat 7 by bolts. The bottom of the connecting seat 2 has a clamping port for clamping the support tube 1. By tightening the bolts, the connecting seat 2 can clamp the support tube 1, realizing quick assembly and disassembly.

[0031] In this embodiment, the device is mounted on the product surface via the fixing base 7. By turning the manual tightening head, the manual threaded rod 3 is rotated, causing the clamping block 4 to press downward against the product surface, forming a reverse support force that effectively counteracts the upward deformation generated during welding. The manual threaded rod 3 can be configured in multiple sets and symmetrically distributed on both sides of the support tube 1 to provide uniform support force and better anti-deformation effect.

A screw 12 and a fixing bolt 14 are threadedly connected to both sides of the U-shaped groove 13, respectively. Different sizes of crossbeams can be accommodated by adjusting the screw 12 and the fixing bolt 14.

[0041] In this embodiment, the manual threaded rod 3 acts as a locking bolt, and the clamping block 4 is detachable to complete the installation of the limiter.
