Description

Technical Field

[0001] This utility model relates to the field of welding machine electrode technology, and in particular to an integral electrode device for a welding machine. Background Technology

[0002] The welding electrode is a key conductive component in the welding circuit, responsible for transmitting welding current to the workpiece and achieving metal fusion under the heat of the electric arc.

[0003] Currently, the existing electrodes are completely fixed to the electrode base by clamping devices and slag baffles. Due to gaps and installation tolerances between the devices, the electrodes may move or shift between the clamping devices. This causes the electrodes to shift or twist when clamping the welding machine's electrodes to the rails. Because the electrodes cannot make close contact with other components, gaps may appear. During the power-on process, this can cause electrical arcing that damages the electrodes and electrode base. This problem can easily lead to the surface of the electrode base being milled off by 4-5mm. If this milling is repeated, the electrode base will be destroyed, resulting in significant losses.

[0004] Therefore, this application proposes an integral electrode device for a welding machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated electrode device for a welding machine, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integral electrode device for a welding machine includes: an electrode body, with clamping blocks on both sides of the electrode body, and a base movably engaged at the bottom ends of the electrode body and the clamping blocks; the electrode body and the base, and the clamping blocks and the base, are fixed by screws; a limiting component is provided between the electrode body and the clamping blocks, the limiting component including a locking block and a bolt, and engaging grooves are provided on both sides of the clamping blocks, one end of the locking block being triangular, and the triangular end of the locking block being able to engage in the corresponding engaging groove.

[0008] According to the overall electrode device of the welding machine, positioning holes are provided at both the front and rear ends of the electrode body, and the base is provided with a through hole at the corresponding positioning hole position.

[0009] According to the overall electrode device of the welding machine, the positioning hole is provided with a steel thread, and the screw moves through the round hole and the corresponding positioning hole.

[0010] According to the overall electrode device of the welding machine, the top of the clamping block is provided with two sets of first circular mounting cavities, and the base cavity is provided with mounting holes at the corresponding positions of the first circular mounting cavities. The screw moves through the first circular mounting cavity and the corresponding mounting hole and is threadedly connected to the nut.

[0011] According to the overall electrode device of the welding machine, the locking groove is triangular prism-shaped, and the end of the locking block away from the locking groove is rectangular.

[0012] According to the overall electrode device of the welding machine, a second circular mounting cavity is provided on the side wall of the two sets of clamping blocks that are far apart from each other, and a rectangular groove is provided on the side wall of the two sets of clamping blocks that are close to each other, and the rectangular end of the clamping block is movably engaged in the corresponding rectangular groove.

[0013] According to the overall electrode device of the welding machine, a through hole is opened between the second circular mounting cavity and the corresponding rectangular groove. A threaded mounting seat is inlaid on the side of the locking block away from the locking groove. The bolt moves through the through hole and is threadedly connected to the threaded mounting seat.

[0014] This utility model provides an integral electrode device for a welding machine. It has the following advantages:

[0015] (1) This utility model sets up a snap-fit ​​connection between the electrode body, the clamping block and the base and a steel thread fastening structure. The screw passes through the round hole and forms a shear-resistant anchor with the steel thread in the positioning hole on one side of the electrode body. At the same time, the first round mounting cavity at the top of the clamping block and the bolt fixing at the bottom mounting hole are used to achieve a rigid connection between the electrode body and the base. This design significantly enhances the overall structure's anti-displacement ability and shear resistance, effectively suppresses the displacement of the electrode body during welding, and reduces defects such as false welding and spatter caused by displacement.

[0016] (2) By setting a bidirectional constraint limiting component and a threaded mounting seat, the triangular tip of the clamping block is precisely wedged into the clamping groove, the rectangular end is embedded in the rectangular groove, and the bolt passes through the through hole and locks with the threaded mounting seat, forming a bidirectional mechanical constraint in the horizontal and vertical directions, so that the electrode body, clamping block and base are tightly connected as a whole, which not only eliminates the risk of electrode movement and electric arcing, but also greatly reduces the contact resistance and current fluctuation due to the fine treatment of the electrode body surface, ensuring a stable and efficient welding process.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-6 As shown, this utility model is an integral electrode device for a welding machine, including an electrode body 10. Clamping blocks 11 are provided on both sides of the electrode body 10. The bottom ends of the electrode body 10 and the clamping blocks 11 are movably engaged with a base 12. The electrode body 10 and the base 12, as well as the clamping blocks 11 and the base 12, are fixed by screws. The surface roughness Ra of the electrode body 10 is 0.4μm, which significantly reduces the contact resistance and reduces current fluctuations during welding. The engaging arrangement of the base 12 constrains the electrode body 10 and the clamping blocks 11, effectively clamping the electrode body 10 and preventing gaps from appearing between the electrode body 10 and the base 12.

[0027] like Figure 1-2 As shown, positioning holes 14 are provided at both the front and rear ends of the electrode body 10, and circular holes 13 are provided through the base 12 at the corresponding positions of the positioning holes 14. Steel thread is provided in the positioning holes 14, and the screw moves through the circular hole 13 and the steel thread in the corresponding positioning hole 14. The screw and the steel thread cooperate to improve the shear resistance of the device, prevent the electrode body 10 from being misaligned, and reduce welding defects caused by the misalignment of the electrode body 10.

[0028] like Figure 3As shown, the top of the clamping block 11 has two sets of first circular mounting cavities 15. The cavity of the base 12 has mounting holes 16 at the corresponding positions of the first circular mounting cavities 15. The screw moves through the first circular mounting cavity 15 and the corresponding mounting hole 16 and is threaded with a nut, thereby fixing the clamping block 11 and the base 12.

[0029] like Figure 4 As shown, a limiting component is provided between the electrode body 10 and the clamping block 11. The limiting component includes a locking block 20 and a bolt. Both sides of the clamping block 11 are provided with engagement grooves 17. One end of the locking block 20 is triangular, and the triangular tip of the locking block 20 is precisely wedged into the engagement groove 17 to achieve bidirectional constraint on the electrode body 10. Whether in the horizontal or vertical direction, it can limit its unnecessary movement, which significantly improves the stability and accuracy of the electrode body 10. The engagement groove 17 is triangular prism-shaped, and the end of the locking block 20 away from the engagement groove 17 is rectangular, which facilitates engagement with the rectangular groove 19.

[0030] like Figure 5-6 As shown, each of the two sets of clamping blocks 11 has a second circular mounting cavity 18 on the side wall away from each other, providing space for bolt installation. A rectangular groove 19 is formed on the side wall of the two sets of clamping blocks 11 close to each other, and the rectangular end of the locking block 20 is movably engaged in the corresponding rectangular groove 19. A through hole 22 is formed between the second circular mounting cavity 18 and the corresponding rectangular groove 19. A threaded mounting seat 21 is embedded on the side of the locking block 20 away from the engaging groove 17. The bolt moves through the through hole 22 and is threadedly connected to the threaded mounting seat 21. By threading the bolt through the through hole 22 and connecting it to the threaded mounting seat 21 on the locking block 20, the locking block 20 can be firmly fixed to the clamping block 11, ensuring that the locking block 20 will not loosen during long-term welding operations and guaranteeing the continuous effectiveness of the limiting component. The triangular tips of the two sets of locking blocks 20 are precisely wedged into the engaging groove 17, thus connecting the device into a stable whole. The electrode body 10 will not shift or move during welding, avoiding electrical sparking during welding.

[0031] The implementation principle of the integral electrode device for a welding machine according to this utility model is as follows:

[0032] First, place the electrode body 10 on the base 12 and initially clamp it with the clamping blocks 11 on both sides. Then, use screws to firmly fix the clamping blocks 11 to the base 12 through the first circular mounting cavity 15 at the top of the clamping block 11 and the corresponding mounting hole 16 on the base 12, and with nuts. At the same time, use screws to fasten the bottom of the electrode body 10 to the base 12 through the circular hole 13 on the base 12 and the corresponding positioning hole 14 with steel thread on the electrode body 10. The steel thread design significantly enhances the shear resistance of this connection point.

[0033] Next, the rectangular end of the locking block 20 is inserted into the rectangular groove 19 on the side wall of the clamping block 11. Then, a bolt is inserted through the through hole 22 on the outer side wall of the clamping block 11. The bolt passes through the through hole 22 and is threadedly connected to the threaded mounting seat 21 embedded on the locking block 20. The bolt is tightened to firmly press and fix the locking block 20 on the clamping block 11. During this process, the triangular tip of the locking block 20 is precisely wedged into the engagement groove 17 on the side of the electrode body 10.

[0034] Finally, the electrode body 10 is reliably constrained in the structure composed of the clamping block 11 and the base 12. In particular, the triangular tip of the locking block 20 is wedged into the locking groove 17, forming a bidirectional constraint force from the two clamping blocks 11 toward the electrode body 10. This makes the electrode body 10 tightly connected with the clamping block 11 and the base 12 into a stable whole, effectively eliminating the fit gap and greatly improving the assembly rigidity and stability.
