Description

Technical Field

[0001] This utility model relates to the field of spot welding machine technology, specifically to an adjustable spot welding machine that can be precisely positioned. Background Technology

[0002] A spot welding machine is a device that uses the electrothermal effect for welding. It mainly consists of welding electrodes, spring pressure plates, a transformer, and control circuitry. Its working principle is based on the instantaneous short circuit between positive and negative electrodes to generate an electric arc, which melts the solder and the material being welded, thus achieving the welding purpose. A precisely positioned adjustable spot welding machine is an advanced welding device that combines precise positioning with adjustable welding parameters, enabling high-precision weld point positioning and stable weld quality during the welding process. This type of spot welding machine is typically equipped with an advanced positioning system and adjustable welding parameters, allowing it to adapt to different welding needs and complex welding tasks.

[0003] As disclosed in Chinese Patent CN220259835U, an adjustable spot welding machine with precise positioning is designed to allow for precise positioning of the upper and lower welding electrodes. When it is necessary to adjust the upper and lower welding electrodes to be on the same vertical line, simply rotating the adjustment handwheel causes the connecting seat to move laterally through the adjustment structure. This changes the lateral position of the lower welding electrode. Furthermore, through the coordinated use of the infrared transmitter and receiver, the lower welding electrode can be adjusted to be on the same vertical line as the upper welding electrode, thereby achieving precise positioning and improving subsequent welding efficiency.

[0004] Although the upper and lower welding electrodes can be aligned in this structure, misalignment occurs when the alignment is incorrect. Since the structure lacks a protective mechanism, we propose an adjustable spot welding machine that can precisely position the aligned welding electrodes for secondary positioning to improve welding accuracy. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable spot welding machine that can be precisely positioned, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable spot welding machine with precise positioning, comprising a spot welding machine body, a lifting mechanism fixedly installed inside the spot welding machine body, an adjustment mechanism disposed below the lifting mechanism, and a processing component disposed inside the spot welding machine body, the processing component including a positioning component disposed below the lifting mechanism, and a protective component disposed outside the positioning component.

[0007] Preferably, the positioning component includes an upper welding electrode fixedly installed at the bottom of the lifting mechanism, a lower welding electrode fixedly installed on the top surface of the adjusting mechanism, a positioning rod hinged to the top surface of the lower welding electrode, a first magnetic block fixedly installed inside the positioning rod, a second magnetic block slidably installed inside the positioning rod, a slide rod fixedly installed on the side wall of the second magnetic block, a buffer pad fixedly installed on the side of the slide rod away from the second magnetic block, and a limiting frame slidably installed on the outer wall of the positioning rod.

[0008] Preferably, the protective component includes a collar fixedly installed at the bottom of the lifting mechanism, a limit ring fixedly installed on the inner wall of the collar, a sliding ring slidably disposed inside the collar, a protective ring fixedly installed at the bottom of the sliding ring, and a rubber pad fixedly installed at the end of the protective ring away from the sliding ring.

[0009] Preferably, the buffer pad is made of rubber, and the first magnetic block and the second magnetic block are magnetically repulsive. Under their restriction, the collision force between the upper welding electrode and the positioning rod can be buffered.

[0010] Preferably, the outer wall of the limiting frame is slidably connected to the positioning rod and the lower welding electrode at the hinge. The bottom of the upper welding electrode has a positioning hole. When the limiting frame slides upward, the positioning rod can be folded. When the upper welding electrode and the lower welding electrode are aligned, the positioning rod drives the buffer pad to slide with the positioning hole at the bottom of the upper welding electrode.

[0011] Preferably, the rubber pad is made of rubber and is slidably disposed inside the collar. When the collar and the protective ring move downward, the rubber pad contacts the workpiece first, thus avoiding scratching the surface of the workpiece.

[0012] Preferably, the outer wall of the protective ring is slidably disposed with the inner side of the limiting ring, and the outer wall of the slip ring is slidably disposed with the inner side of the collar. Under the restriction of the slip ring, the protective ring and the collar can be prevented from falling off.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This precisely positioned adjustable spot welding machine consists of a positioning assembly. When welding a workpiece, the upper and lower welding electrodes need to be aligned. The adjusting mechanism precisely adjusts the lower welding electrode. The workpiece is then placed between the upper and lower welding electrodes. The lifting mechanism is activated, pushing the upper welding electrode downwards. When the positioning rod aligns with the positioning hole at the bottom of the upper welding electrode, the upper and lower welding electrodes are precisely aligned. If a deviation occurs between the lower and upper welding electrodes, the bottom of the upper welding electrode contacts and presses against the buffer pad, causing the buffer pad to slide the second magnetic block into the first magnetic block. The upper welding electrode is then moved upwards, and the lower welding electrode is adjusted again, ensuring the buffer pad and second magnetic block are aligned. Under the magnetic repulsion constraint of the first magnetic block, the collision between the upper welding electrode and the positioning rod is buffered, preventing the bottom of the upper welding electrode from directly impacting the positioning rod. When maintenance of the lower welding electrode and the upper welding electrode is required, the limiting frame is pulled so that the limiting frame no longer restricts the hinge between the positioning rod and the lower welding electrode, and the positioning rod is folded, making it easier for the operator to maintain the lower welding electrode and the upper welding electrode. This structure can perform secondary positioning of the adjusted lower welding electrode and the upper welding electrode to avoid deviation between the lower welding electrode and the upper welding electrode, thereby improving welding accuracy (the spot welding machine body, lifting mechanism, adjusting mechanism, upper welding electrode and lower welding electrode are existing disclosed technologies in the prior art, therefore their structures are not fully described in this case).

[0015] 2. This precisely positioned adjustable spot welding machine includes a protective component. When the lifting mechanism moves the upper welding electrode downwards and works in conjunction with the lower welding electrode to weld the workpiece, welding foreign objects may appear during the welding process, requiring protective treatment. When the lifting mechanism moves the collar downwards, the protective ring also moves downwards. When the rubber pad contacts the workpiece, as the lifting mechanism descends, the collar moves the limiting ring to slide on the outer wall of the protective ring, thus securing the protective ring. Under the protection of the protective ring and the collar, welding foreign objects are prevented from injuring the operator. Under the restriction of the rubber pad, collision damage to the workpiece can be avoided. This structure can provide welding protection and prevent welding impurities from flying out and injuring the operator. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the adjustable spot welding machine with precise positioning provided by this utility model is as follows: Figures 1 to 6 As shown: An adjustable spot welding machine with precise positioning, including a spot welding machine body 1;

[0025] The spot welding machine body 1 has a lifting mechanism 2 fixedly installed inside;

[0026] An adjustment mechanism 3 is provided below the lifting mechanism 2;

[0027] The processing component 4 is located inside the spot welding machine body 1. The processing component 4 includes a positioning component 41 located below the lifting mechanism 2. The positioning component 41 includes an upper welding electrode 411 fixedly installed at the bottom of the lifting mechanism 2, a lower welding electrode 412 fixedly installed on the top surface of the adjusting mechanism 3, a positioning rod 413 hinged to the top surface of the lower welding electrode 412, a first magnetic block 414 fixedly installed inside the positioning rod 413, a second magnetic block 415 slidably installed inside the positioning rod 413, a slide rod 416 fixedly installed on the side wall of the second magnetic block 415, a buffer pad 417 fixedly installed on the side of the slide rod 416 away from the second magnetic block 415, and a limiting frame 418 slidably installed on the outer wall of the positioning rod 413.

[0028] In this embodiment, when welding the workpiece, it is necessary to align the upper welding electrode 411 with the lower welding electrode 412. The adjusting mechanism 3 precisely adjusts the lower welding electrode 412. The workpiece is then placed between the upper and lower welding electrodes 411. The lifting mechanism 2 is activated, pushing the upper welding electrode 411 downwards. When the positioning rod 413 is fitted with the positioning hole at the bottom of the upper welding electrode 411, the upper and lower welding electrodes 412 are precisely aligned. When a deviation occurs between the lower and upper welding electrodes 412, the bottom of the upper welding electrode 411 contacts and presses against the buffer pad 417, causing the buffer pad 417 to slide the second magnetic block 415 into the first magnetic block 414. The upper welding electrode 411 is then moved upwards, and the lower welding electrode 412 is adjusted again. The buffer pad 417, the second magnetic block 415, and the first magnetic block 414 are then in contact. Under the mutual repulsion constraint, the collision between the upper welding electrode 411 and the positioning rod 413 is buffered to prevent the bottom of the upper welding electrode 411 from directly impacting the positioning rod 413. When maintenance of the lower welding electrode 412 and the upper welding electrode 411 is required, the limiting frame 418 is pulled so that the limiting frame 418 no longer restricts the hinge of the positioning rod 413 and the lower welding electrode 412, and the positioning rod 413 is folded, making it easier for the operator to maintain the lower welding electrode 412 and the upper welding electrode 411. This structure can reposition the lower welding electrode 412 and the upper welding electrode 411 after adjustment, avoiding deviation between the lower welding electrode 412 and the upper welding electrode 411, thereby improving welding accuracy (the spot welding machine body 1, lifting mechanism 2, adjusting mechanism 3, upper welding electrode 411 and lower welding electrode 412 are existing disclosed technologies in the prior art, therefore their structures are not fully described in this case).

[0029] Furthermore, the buffer pad 417 is made of rubber, and the first magnetic block 414 and the second magnetic block 415 are magnetically repelled. Under their restriction, the collision force between the upper welding electrode 411 and the positioning rod 413 can be buffered.

[0030] Furthermore, the outer wall of the limiting frame 418 is slidably connected to the positioning rod 413 and the lower welding electrode 412 at the hinge. The bottom of the upper welding electrode 411 has a positioning hole. When the limiting frame 418 slides upward, the positioning rod 413 can be folded. When the upper welding electrode 411 and the lower welding electrode 412 are aligned, the positioning rod 413 drives the buffer pad 417 to slide with the positioning hole at the bottom of the upper welding electrode 411.

[0031] Example 2: Based on Example 1, a preferred embodiment of the adjustable spot welding machine with precise positioning provided by this utility model is as follows: Figures 1 to 6As shown: The protective component 42 includes a collar 421 fixedly installed at the bottom of the lifting mechanism 2. A limit ring 422 is fixedly installed on the inner wall of the collar 421. A slip ring 423 is slidably arranged inside the collar 421. A protective ring 424 is fixedly installed at the bottom of the slip ring 423. A rubber pad 425 is fixedly installed at the end of the protective ring 424 away from the slip ring 423.

[0032] In this embodiment, when the lifting mechanism 2 drives the upper welding electrode 411 to move downward and cooperates with the lower welding electrode 412 to weld the workpiece, welding foreign objects will appear during the welding process, which need to be protected. When the lifting mechanism 2 drives the collar 421 to move downward, the protective ring 424 also moves downward. When the rubber pad 425 contacts the workpiece, as the lifting mechanism 2 descends, the collar 421 drives the limiting ring 422 to slide on the outer wall of the protective ring 424, thus covering the protective ring 424. Under the protection of the protective ring 424 and the collar 421, welding foreign objects are prevented from injuring the operator. Under the restriction of the rubber pad 425, the workpiece can be prevented from being damaged by collision. This structure can protect the welding process and prevent welding impurities from flying out and injuring the operator.

[0033] Furthermore, the rubber pad 425 is made of rubber and is slidably disposed inside the collar 421. When the collar 421 and the protective ring 424 move downward, the rubber pad 425 contacts the workpiece first, thus preventing the workpiece surface from being scratched.

[0034] In addition, the outer wall of the protective ring 424 is slidably disposed with the inner side of the limiting ring 422, and the outer wall of the slip ring 423 is slidably disposed with the inner side of the collar 421. Under the restriction of the slip ring 423, the protective ring 424 and the collar 421 can be prevented from falling off.

[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
