Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic joint processing, and specifically relates to a hydraulic joint welding device. Background Technique

[0002] As an important component in fluid transmission and hydraulic systems, the quality of hydraulic joints directly affects the sealing performance and working stability of the system. The welding of hydraulic joints is a crucial step in its production process. However, when the existing welding devices weld two structural components of a hydraulic joint, it is often difficult to ensure the concentric docking and synchronous operation of the two groups of structural components. This problem leads to uneven seams and discontinuous welds during the welding process, thereby affecting the welding quality and increasing the difficulty of subsequent processing or maintenance.

[0003] The existing hydraulic joint welding devices usually adopt simple fixtures and welding methods. During the welding process, due to the lack of precise synchronous control, the two groups of welded structural components are prone to position deviation, making it difficult to ensure that they maintain a completely consistent welding state. In addition, the feeding systems of traditional welding devices are mostly single-axis or simple mechanical adjustments, and the positioning and welding paths of the welding torches are not precise enough, which further reduces the welding accuracy and efficiency.

[0004] With the continuous improvement of the precision requirements for hydraulic joint products, the limitations of existing devices are gradually emerging. Especially during the welding process, the uniformity and sealing performance of the welds have a direct impact on the final use performance of the products. The existing technologies are difficult to achieve precise automatic adjustment, the operation is complex, and the welding efficiency is low, which greatly restricts the batch and automatic production of hydraulic joints. Therefore, there is an urgent need for a hydraulic joint welding device that can ensure the synchronous operation of two groups of structural components, has high welding precision, and has uniform and continuous welds, so as to improve the welding quality and efficiency.

The adjusting slide base 21 includes two groups that are slidably installed in the assembly chute 11 and are symmetrically arranged. The adjusting lead screw 22 and the spline shaft 23 are both rotatably installed in the assembly chute 11. Two sections of thread grooves with opposite spiral directions are provided on the adjusting lead screw 22, and the two thread grooves are respectively screwed with the two adjusting slide bases 21. The two fixture components are respectively rotatably installed on the two adjusting slide bases 21.

[0033] The setting of the processing table 1 can ensure the stable assembly of the components involved thereon, and then ensure the stable operation of each component, and further enable the hydraulic joint assembly and welding work to proceed stably.

[0034] When processing the hydraulic joint, the two sets of structural parts to be welded are respectively clamped and fixed by the corresponding fixture assemblies. Since the two fixture assemblies are horizontally opposed, the two sets of structural parts fixed can automatically achieve concentric docking.

[0035] When controlling and adjusting the operation of the lead screw 22, the two sets of oppositely arranged thread grooves thereon can drive the two sets of adjusting sliders 21 and the fixture assemblies and hydraulic joint weldments assembled thereon to approach and dock with each other.

The horizontal feeding axis of the dual-axis feeding module 4 is parallel to the axis of the fixture assembly, and the vertical feeding axis of the dual-axis feeding module 4 is perpendicular to the axis of the fixture assembly.

[0037] When adjusting by controlling the dual-axis feeding module 4, it can drive the welding torch 5 assembled thereon to adjust its posture, so that the welding torch 5 is aligned with the connection position of the two sets of hydraulic joint structural parts, and the connection position of the structural parts is welded by means of the welding torch 5.

[0038] During the welding process, the spline shaft 23 drives the two sets of fixture assemblies and the structural parts fixed thereon to rotate synchronously.
