Description

Technical Field

[0001] This utility model relates to the field of electrode arm technology, and in particular to a splicing electrode arm. Background Technology

[0002] Nowadays, with the rapid advancement of technology, there are more and more welded parts needed in our lives. Of course, in resistance welding, the electrode arm is a consumable part, and resistance welding is widely used in the automotive processing field. The main function of the electrode arm in resistance welding is to transmit current and apply pressure.

[0003] Chinese Patent Publication No. CN214350218U discloses a segmented electrode arm, including a first electrode arm body and a second electrode arm body. An electrode nozzle is provided at the end of the first electrode arm body away from the second electrode arm body, and a connector is provided at the end of the second electrode arm body away from the first electrode arm body. A tube is fixedly provided on the end face of the first electrode arm body near the second electrode arm body, and a slot is formed on the second electrode arm body corresponding to the tube. The slot is ring-shaped and its shape is adapted to the tube. The inner diameter of the tube is larger than the inner diameter of the slot. Threads are provided on the outer wall of the tube and the groove wall of the slot, and the tube and slot are threadedly connected. Its structure is novel, being segmented, and can be disassembled and reassembled. If a part of the electrode arm is damaged, it can be replaced, reducing production costs and waste.

[0004] However, compared with existing technologies and prior art documents, the existing splicing electrode arms adopt a segmented structure that can be disassembled and assembled. Because the segmented structure uses a threaded connection, long-term use and frequent disassembly and assembly cause the threads to wear down, making it impossible to connect the replaced electrode arms. Utility Model Content

[0005] The main purpose of this invention is to provide a splicing electrode arm.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A splicing electrode arm includes an electrode arm comprising a first arm body and a second arm body, wherein a fixing sleeve is provided on the outer side of the connection between the first arm body and the second arm body, and multiple sets of limiting grooves are evenly opened in the fixing sleeve, a fixing mechanism is installed at the top of the first arm body, a limiting mechanism is provided at the bottom of the second arm body, and a threaded hole is opened on the second arm body, wherein a fixing bolt is rotatably connected in the threaded hole.

[0008] Preferably, one end of the first arm body has an arc-shaped structure, and an electrode nozzle is installed at the arc-shaped end of the first arm body.

[0009] Preferably, the fixing mechanism includes a base, a boss, and a groove, wherein the diameter of the boss is larger than the diameter of the base.

[0010] Preferably, the groove is formed on the boss, and the number of the groove and the limiting groove are the same.

[0011] Preferably, the limiting mechanism includes a limiting plate, a slot, a telescopic spring, and a limiting block. The limiting plate is located outside the second arm, and the number of limiting plates is the same as the number of limiting slots.

[0012] Preferably, the slot is formed in the inner wall of the second arm, and one end of the telescopic spring is fixed in the slot.

[0013] Preferably, the other end of the telescopic spring is fixedly connected to the limiting block, and both the top and bottom ends of the limiting block are inclined structures.

[0014] The beneficial effects of this technology are:

[0015] This utility model allows for the following steps when replacing one set of booms: the operator inserts the limiting plate from the limiting mechanism into one side of the limiting groove. During insertion, the limiting block is supported by the telescopic spring. After insertion, the limiting plate is rotated to one side of the limiting groove, at which point the limiting block is located on one side of the bottom of the boss, thus limiting the second boom. After limiting, the operator inserts the fixing bolt into the threaded hole and through the base, thereby connecting the first and second booms. This allows for multiple reuses and avoids damage to the threads that would prevent subsequent replacement. Attached Figure Description

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-3 As shown, this embodiment provides a splicing electrode arm, including an electrode arm 1. The electrode arm 1 includes a first arm body 101 and a second arm body 102. A fixing sleeve 3 is provided on the outer side of the connection between the first arm body 101 and the second arm body 102. The fixing sleeve 3 can limit the first arm body 101 and the second arm body 102. Multiple sets of limiting grooves 4 are evenly opened in the fixing sleeve 3. The limiting grooves 4 can limit the limiting plate 601. A fixing mechanism 5 is installed at the top of the first arm body 101. A limiting mechanism 6 is provided at the bottom of the second arm body 102. A threaded hole 7 is opened on the second arm body 102. A fixing bolt 8 is rotatably connected in the threaded hole 7. The fixing bolt 8 can fix the first arm body 101 and the second arm body 102 through the threaded hole 7.

[0023] like Figure 1 As shown, one end of the first arm 101 has an arc-shaped structure, and an electrode nozzle 2 is installed at the arc-shaped end of the first arm 101, so that the electrode nozzle 2 can be fixed by the electrode arm 1 to make it work.

[0024] like Figure 2 As shown, the fixing mechanism 5 includes a base 501, a boss 502, and a slide groove 6503. The diameter of the boss 502 is larger than the diameter of the base 501, which facilitates the support of the limiting mechanism 6 through the fixing mechanism 5.

[0025] like Figure 2 As shown, the slide groove 6503 is formed on the boss 502, and the number of slide grooves 6503 and the limiting groove 4 are the same, which enables the limiting block 604 in the limiting mechanism 6 to move to the bottom of the boss 502 through the slide groove 6503.

[0026] like Figures 1-3 As shown, the limiting mechanism 6 includes a limiting plate 601, a slot 602, a telescopic spring 603, and a limiting block 604. The limiting plate 601 is located outside the second arm body 102, and the number of limiting plates 601 and limiting slots 4 are the same, so that the second arm body 102 can be connected to the first arm body 101 through the limiting mechanism 6.

[0027] like Figures 1-3 As shown, the slot 602 is formed in the inner wall of the second arm body 102, and one end of the telescopic spring 603 is fixed in the slot 602, so that the telescopic spring 603 can be installed in the second arm body 102 through the slot 602.

[0028] like Figure 2As shown, the other end of the telescopic spring 603 is fixedly connected to the limiting block 604, and both the top and bottom ends of the limiting block 604 are inclined structures, which facilitates the fixing of one end of the telescopic spring 603 to the limiting block 604.

[0029] The working principle of this device is as follows: When replacing the second arm 102, the operator places the new second arm 102 in the fixed sleeve 3, aligns the limiting plate 601 on the outside of the second arm 102 with one side of the upper limit groove 4 of the fixed sleeve 3, and then inserts the second arm 102. During the insertion process, the limiting block 604 in the limiting mechanism 6 can move along the slide groove 6503 to the bottom of the boss 502. After the second arm 102 is inserted, the operator rotates the second arm 102, causing the limiting plate 601 to rotate to the other side of the limiting groove 4. At this time, the boss 502 can limit the limiting plate 601. After the rotation is completed, the operator uses the fixing bolt 8 to pass through the base 501 and the second arm 102, and connects the fixing bolt 8 with the threaded hole 7 on the second arm 102, so that the first arm 101 and the second arm 102 can be quickly connected.

[0030] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
