Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically to a clamping mechanism that enables the use of both arc welding and spot welding processes. Background Technology

[0002] Current resistance welding processes generate resistance heat by conducting positive and negative electrodes. Arc welding also requires the parts to be connected to a circuit, necessitating an electrode wire to connect the parts. Arc welding and spot welding require two independent circuit connection structures. These two circuit connection structures must be operated separately and independently during operation; they cannot coexist, otherwise, there is a risk of failure in the spot welding process. To avoid this failure risk, two sets of tooling must be used for the corresponding processes, resulting in lower welding efficiency and increased costs.

[0003] Therefore, it is urgent to propose a new solution to the above problems. Summary of the Invention

[0004] This invention provides a fixture mechanism that enables the use of both arc welding and spot welding processes, which solves the problem that the existing technology requires two independent circuit connection structures for arc welding and spot welding, resulting in low welding efficiency and increased costs.

An equipment electrode wire connecting block is fixed on the first insulating block, and a gripper electrode wire connecting block is fixed on the second insulating block. The equipment electrode wire connecting block is located above the gripper electrode wire connecting block. The separation and engagement of the equipment electrode wire connecting block and the gripper electrode wire connecting block are achieved by driving the equipment electrode wire connecting block to move up and down through the telescopic mechanism.

[0006] Furthermore, the first insulating block and the device electrode wire connecting block are fixedly connected by a pin, and an insulating sleeve is provided on the outside of the pin. The first insulating block and the device electrode wire connecting block are also provided with an insulating gasket.

[0012] As another preferred embodiment, the contact surfaces of the device electrode wire connecting block and the gripper electrode wire connecting block are concave-convex mating surfaces.

[0013] Compared to existing technologies, this invention utilizes a fixture structure consisting of a telescopic mechanism, a first insulating block, a second insulating block, a device electrode wire connecting block, and a gripper electrode wire connecting block to achieve the separation and connection of the device electrode wire connecting block and the gripper electrode wire connecting block.

[0020] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with accompanying drawings. Figures 1-5 The details are as follows.

[0021] like Figures 1-4 As shown, Embodiment 1 of this utility model provides a fixture mechanism for using both arc welding and spot welding processes. It includes a first insulating block 21 fixed to the movable part 11 of a telescopic mechanism 1 and a second insulating block 22 fixed to the fixed part 12. An equipment electrode wire connecting block 31 is fixed to the first insulating block 21, and a gripper electrode wire connecting block 32 is fixed to the second insulating block 22. The equipment electrode wire connecting block 31 is located above the gripper electrode wire connecting block 32. The separation and engagement of the equipment electrode wire connecting block 31 and the gripper electrode wire connecting block 32 are achieved by driving the equipment electrode wire connecting block 31 up and down through the telescopic mechanism 1. The equipment electrode wire connecting block 31 and the gripper electrode wire connecting block 32 are made of copper, and the first insulating block 21 and the second insulating block 22 are made of polyurethane.

[0022] This invention utilizes a fixture structure comprising a telescopic mechanism, a first insulating block, a second insulating block, an equipment electrode wire connecting block, and a gripper electrode wire connecting block to achieve the separation and connection of the equipment electrode wire connecting block and the gripper electrode wire connecting block. When separated, spot welding can be performed; when connected, arc welding can be performed. This fixture structure allows for the simultaneous and sequential execution of both spot welding and arc welding on the same fixture, making the entire production process more flexible.

[0023] In this embodiment, such as Figure 1 As shown, it includes a part positioning pin 41, a leak detection and electrical detection bracket 42, a part positioning pin 43, a first part clamping pressure head 44, a second part clamping pressure head 45, a gun changing connection plate 46, and a gripper head main support rod 47. The clamping structure is located near the gun changing connection plate 46, which minimizes the length of the equipment electrode wire connection line and also provides sufficient clearance.

[0024] In this embodiment, the first insulating block 21 and the device electrode wire connecting block 31 are fixedly connected by a pin. An insulating sleeve is provided on the outside of the pin. An insulating gasket is also provided on the first insulating block 21 and the device electrode wire connecting block 31, thus ensuring the insulation of the entire fixture structure.

[0025] In this embodiment, the second insulating block 22 and the gripper electrode wire connecting block 32 are fixedly connected by a pin. An insulating sleeve is provided on the outside of the pin. An insulating gasket is also provided on the second insulating block 22 and the gripper electrode wire connecting block 32, thus ensuring the insulation of the entire fixture structure.

[0026] In this embodiment, the telescopic mechanism 1 is a telescopic cylinder. The movable part 11 includes a cylinder head fixedly disposed on the telescopic cylinder and a first connecting plate 13 disposed on the cylinder head. The first insulating block 21 is fixedly disposed below the first connecting plate 13. The fixed part 12 includes a cylinder seat fixedly disposed on the telescopic cylinder and a second connecting plate 14 disposed on the cylinder seat. The second insulating block 22 is fixedly disposed above the second connecting plate 14. This makes it easier to separate and engage the equipment electrode wire connecting block 31 and the gripper electrode wire connecting block 32.

[0027] In this embodiment, the first connecting plate 13 and the first insulating block 21 are fixedly connected by a pin. An insulating sleeve is provided on the outside of the pin. The first connecting plate 13 and the first insulating block 21 are also provided with insulating gaskets, which ensures the insulation of the entire fixture structure.

[0028] In this embodiment, the second connecting plate 14 and the second insulating block 22 are fixedly connected by pins. An insulating sleeve is provided on the outside of the pins. The second connecting plate 14 and the second insulating block 22 are also provided with insulating gaskets, which ensures the insulation of the entire fixture structure. The first insulating block 21 and the second insulating block 22 are arranged in parallel, which can save overall space.

[0029] In the first embodiment of this utility model, as Figure 4 As shown, the contact surfaces of the device electrode wire connecting block 31 and the gripper electrode wire connecting block 32 are flat, wherein the lower surface of the device electrode wire connecting block 31 partially abuts against the upper surface of the gripper electrode wire connecting block 32, which facilitates manufacturing.

[0030] In the second embodiment of this utility model, as follows: Figure 5 As shown, the contact surfaces of the device electrode line connecting block 31 and the gripper electrode line connecting block 32 are concave-convex mating surfaces. The device electrode line connecting block 31 is provided with a downwardly protruding protrusion 311, and the upper end of the gripper electrode line connecting block 32 is provided with a concave-convex recess that mates with the protrusion 311. This increases the contact area between the two and makes the overall connection more stable.

[0031] In this embodiment, one end of the cable connecting the gripper is fixed to the gripper electrode wire connecting block 32, and the other end is fixed to the pressure head where the gripper contacts the part. One end of the cable connecting the equipment is fixed to the equipment electrode wire connecting block 31, and the other end is connected to the ground electrode of the arc welding equipment through the robot arm connector. During spot welding, the workpiece to be welded cannot be connected to the electrode wires of other equipment, but only to the gripper electrode wire connecting block 32; otherwise, current shunting will occur, leading to abnormal product quality. In addition, during arc welding, the workpiece to be welded must be connected to the equipment electrode wire connecting block 31 and the gripper electrode wire connecting block 32 in sequence to achieve arc ignition welding.

[0032] The above-described utility model only illustrates the implementation methods of the present utility model and should not be construed as limiting the scope of the utility model patent, nor is it a limitation on the structure of the present utility model embodiments in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present utility model embodiments, and these all fall within the protection scope of the present utility model embodiments.
