Description

Technical Field

[0001] The utility model relates to the field of resistance welding, in particular to a quick-detachable resistance welding electrode rod clamping structure. Background Art

[0002] Currently, the welding gun head of a resistance welding machine uses a copper rod with a hole in the middle, into which the electrode rod is inserted and locked. However, when the electrode rod needs to be replaced, it is difficult to remove the electrode rod from the copper rod hole due to the influence of long-term high temperature.

[0003] Therefore, it is necessary to provide a quick-release resistance welding electrode rod clamping structure to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a quick-release resistance welding electrode rod clamping structure.

[0005] The utility model provides a quick-release resistance welding electrode rod clamping structure, comprising an outer sleeve, a mounting seat fixed on the inner side of the outer sleeve, a copper rod symmetrically installed inside the mounting seat, a notch provided at one end of the copper rod, a clip installed at the notch, a semi-circular arc groove provided at the center of one side of the clip and the center of the notch, and the two semi-circular arc grooves form a circular groove, an electrode rod is installed in the circular groove, a mounting hole is provided on the clip, a first threaded hole is provided on the mounting seat, and the clip is connected to the copper rod by screws.

[0006] Preferably, the copper rod is slidably connected to the mounting seat, a copper ring is fixed to the side wall of the copper rod close to one end of the electrode rod, a spring is installed on the outside of the copper rod between the mounting seat and the copper ring, and a blocking plate is provided on the side wall of the copper rod, and the blocking plate cooperates with the end face of the mounting seat.

[0007] Preferably, a flat portion is provided on the side wall of one end of the copper rod away from the electrode rod, and a second threaded hole is symmetrically provided inside the copper rod opposite the flat portion. A limiting column is fixedly connected to the side wall of the copper rod opposite the second threaded hole by a screw, and a sliding groove is provided on the side wall of the outer sleeve, and the limiting column is slidably connected in the sliding groove.

[0008] Preferably, the copper ring is fixedly connected to the copper rod by screws.

[0010] Compared with the related art, the present invention has the following beneficial effects:

[0011] The electrode rod is installed and clamped by a screw-locking clip. Loosening the screw releases the clip, allowing the electrode rod to be easily removed. This makes replacing the electrode rod more convenient and faster than existing structures. The two springs are independently retracted, so they can meet the needs of simultaneous welding at different heights of two welding parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0019] Please refer to Figures 1 to 5 A quick-release resistance welding electrode rod clamping structure, the main components of which include an outer sleeve 1, the inner side of which is firmly connected to a mounting base 2. Inside the mounting base 2, copper rods 3 are symmetrically assembled, and a notch a is cleverly designed at one end of the copper rods 3, and a clip 4 is installed at this notch a. The design of the clip 4 and the notch a is very sophisticated. A semi-circular arc groove b is provided at the center of each side of each of them. When the two semi-circular arc grooves b are merged, a complete circular groove c is formed. This circular groove c is used to install the electrode rod 5. The clip 4 is provided with a mounting hole 6, and the mounting base 2 is provided with a first threaded hole 7. The clip 4 is connected to the copper rod 3 by screws (the screw passes through the mounting hole 6 and is connected to the first threaded hole 7 by thread).

[0020] The connection between the copper rod 3 and the mounting base 2 adopts a sliding connection. This design allows the copper rod 3 to move flexibly within the mounting base 2. A copper ring 8 is also fixed to the end of the side wall of the copper rod 3 near the electrode rod 5. The copper ring 8 and the copper rod 3 are also fixed by screws, which is convenient for both installation and disassembly. A spring 9 is also installed on the outside of the copper rod 3, between the mounting base 2 and the copper ring 8. The design of this spring 9 allows the entire structure to better buffer and adapt when subjected to external forces. The side wall of the copper rod 3 is provided with a blocking plate 10, and the blocking plate 10 is matched with the end face of the mounting base 2.

[0021] A flat portion 11 is provided on the side wall of one end of the copper rod 3 away from the electrode rod 5, and a second threaded hole 12 is symmetrically provided in the copper rod 3 opposite the flat portion 11. A limiting column 13 is fixedly connected to the side wall of the copper rod 3 opposite the second threaded hole 12 by a screw, and a sliding groove 14 is provided on the side wall of the outer sleeve 1, and the limiting column 13 is slidably connected in the sliding groove 14.

[0022] In actual use, a worker can easily grasp the outer sleeve 1 and apply both electrode rods 5 simultaneously to the welded part. When the electrode rods 5 contact the welded part, the welded part pushes against the electrode rods 5, causing the copper rod 3 to slide relative to the outer sleeve 1 (at this point, the limit post 13 slides within the slide 14), thereby compressing the spring 9. Because the two springs 9 are independently retractable, they can meet the requirements of simultaneous welding of two welds at different heights.

[0023] The electrode rod 5 is installed and clamped by means of a screw locking clip 4. When the screw is loosened, the clip 4 is loosened, and the electrode rod 5 can be easily removed. This makes it more convenient and faster to replace the electrode rod 5 than the existing structure.

[0024] The flat surface 11 is connected to the external wires through screws.

[0025] The copper ring 8 is fixedly connected to the copper rod 3 by screws, which is convenient for installation and disassembly.

[0026] The side wall of the copper rod 3 is provided with an annular groove 15, and the blocking plate 10 is clamped in the annular groove 15, which facilitates the installation of the blocking plate 10 (the blocking plate 10 is similar to a retaining spring).

[0027] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
