Description

Technical Field

[0001] This invention relates to the field of shock absorber processing, and more specifically, to a double-ring welding device. Background Technology

[0002] In a vehicle's suspension system, the shock absorber is an indispensable key component. Shock absorber linkages often require welded lifting rings. During welding, it's difficult for operators to manually maintain the lifting rings in the correct position on the linkage; even slight touches can cause slippage or deflection. Even with simple V-blocks or clamps, it's often impossible to simultaneously constrain multiple degrees of freedom of the lifting ring, resulting in unreliable pre-positioning and directly affecting the accuracy of the starting point for subsequent welding. Furthermore, during manual welding, parameters such as the welding torch angle, movement speed, and arc dwell time vary from person to person, leading to unstable weld formation and defects such as porosity, undercut, and insufficient penetration.

[0003] Therefore, providing a double-ring welding device with pre-positioning function that can replace manual welding is a problem that this invention urgently needs to solve. Summary of the Invention

[0004] The purpose of this invention is to provide a double-ring welding device that can quickly and reliably pre-position the rings and connecting rods and achieve automated welding.

The first servo module is used to drive the welding torch to move along a first direction; The second servo module is used to drive the welding torch to move along a second direction, wherein the second horizontal direction is perpendicular to the first horizontal direction in the horizontal plane.

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] like Figure 1-6As shown: This invention provides a double-ring welding device, comprising a welding fixture assembly mounted on a frame 12, a first servo module 7 mounted on both sides of the welding fixture assembly, a second servo module 8 mounted on the output end of the first servo module 7, a welding torch adjustment assembly 9 mounted on the output end of the second servo module 8, and a welding torch 10 mounted on the welding torch adjustment assembly 9. The first servo module 7 drives the welding torch 10 to move along a first direction; the second servo module 8 drives the welding torch 10 to move along a second direction, the second horizontal direction being perpendicular to the first horizontal direction in the horizontal plane. By setting the welding fixture assembly to position the rings and connecting rods, and arranging the first and second servo modules on both sides respectively, the welding torch can automatically move in two mutually perpendicular directions in the horizontal plane, achieving rapid switching and precise positioning of the two rings. This structure replaces the manual hand-held welding torch operation, solving the problem of inconsistent welding torch angle and position during manual welding, and providing a reliable two-dimensional planar motion basis for the sequential automated welding of double rings.

[0021] In a preferred embodiment of the present invention, the first servo module 7 and the second servo module 8 each include a servo motor, a lead screw, and a movable slide that cooperates with the lead screw, with the movable slide serving as an output end. By using a servo motor in conjunction with the lead screw and the movable slide as the driving unit, high-precision, high-repeatability linear displacement can be achieved, resulting in smooth movement and rapid response.

[0022] In a preferred embodiment of the present invention, the welding torch adjustment assembly 9 includes a three-axis moving platform disposed on the output end of the second servo module 8 and a clamping fixture disposed on the output end of the three-axis moving platform, with the welding torch 10 disposed within the clamping fixture. The three-axis moving platform is disposed at the output end of the second servo module, and the welding torch is fixed at its end by the clamping fixture, allowing for fine-tuning in three directions after coarse horizontal positioning of the welding torch. The clamping fixture ensures the stability of the welding torch clamping and prevents torch head displacement caused by welding vibration. This combined structure satisfies the need for rapid, wide-range movement while achieving precise alignment of the welding starting point, significantly improving welding quality. The three-axis moving platform used here is a type known and commonly used in the art.

[0023] In a preferred embodiment of the present invention, the three-axis moving platform includes a first slide moving along a first horizontal direction, a second slide moving along a second horizontal direction, and a third slide moving along a vertical direction. The first, second, and third slides are stacked sequentially, and their respective moving directions are perpendicular to each other. By stacking the first, second, and third slides sequentially with their moving directions perpendicular to each other, a complete three-dimensional fine-tuning system is formed. The operator or control system can independently adjust the position of the welding torch in two horizontal directions and in the vertical direction.

[0024] In a preferred embodiment of the present invention, the welding fixture assembly includes a base 1 fixed to the frame 12, a clamping assembly fixed to the upper end of the base 1, and a lifting ring positioning V-block 6 fixed to the lower end of the base 1. The lifting ring positioning V-block 6 on the base is used to engage the positioning lifting ring, and the clamping assembly can press the connecting rod against the welding surface of the lifting ring.

[0025] In a preferred embodiment of the present invention, in order to effectively press the connecting rod against the welding surface of the lifting ring, the pressing assembly includes a pressing cylinder 2 fixed on the base 1 and a pressing block 3 fixed on the output shaft of the pressing cylinder 2.

[0026] In a preferred embodiment of the present invention, a plurality of connecting rod positioning V-blocks 4 are fixedly fixed at intervals on the side of the seat 1. Fixing a plurality of connecting rod positioning V-blocks at intervals on the side of the seat can provide multi-point radial support and axial limitation for the connecting rods, preventing the connecting rods from bending or twisting during the welding process.

[0027] In a preferred embodiment of the present invention, magnets are provided in the V-grooves of both the lifting ring positioning V-block 6 and the connecting rod positioning V-block 4. Before the clamping assembly is activated, the magnets can keep the lifting ring and the connecting rod in contact, resisting slight touches or vibrations, without requiring manual support from the operator.

[0028] In a preferred embodiment of the present invention, in order to effectively isolate welding spatter, arc radiation and fumes, protect the safety of operators and improve the working environment, a protective cover 11 is provided on the frame 12, the welding fixture assembly is located inside the protective cover 11, and clearance grooves are formed on both sides of the protective cover 11 so that the welding torch 10 can extend from the clearance grooves into the protective cover 11.

[0029] In a preferred embodiment of the present invention, a rotary cylinder is fixed on the base. The rotary cylinder can effectively press the connecting rod into the connecting rod positioning V-block 4, preventing the connecting rod from bending or twisting during the welding process.

[0030] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
