Description

Technical Field

[0001] This utility model relates to the field of spot welding machine technology, specifically to a spot welding machine structure. Background Technology

[0002] A spot welding machine is a device that uses resistance heating to join metals. It generates high temperature and applies pressure at the contact point of the workpiece by using current, so as to achieve fast and efficient connection of metal plates. It is widely used in automobile manufacturing, electronics industry and other fields.

[0003] For example, announcement number CN210908496U, entitled "A Spot Welding Machine," includes a base, a bracket fixed to the upper surface of the base, an upper electrode, a drive device connected to the bracket for driving the upper electrode to move up and down, a spot welding head fixed to the lower surface of the upper electrode, and a lower electrode. A groove is provided on the bracket directly below the upper electrode, and the lower electrode is located inside the groove, with the top of the lower electrode and the top of the bracket containing the groove at the same horizontal plane. At least two movable plates and several sliding grooves are provided on the surface of the bracket containing the groove. The movable plates, along with the slots, blocks, and springs provided on them, restrict the position of the workpiece to be processed. Simultaneously, the limiting structure restricts the position of the movable plates, preventing them from shaking during processing, thus ensuring the accuracy of the spot welding and improving the quality of the spot welding.

[0004] The existing welding machines described above can only clamp and limit the spot welding workpiece during use, and cannot adjust the spot welding position by displacement, which is not very flexible and causes inconvenience to users. Therefore, they do not meet the current needs, and a new spot welding machine structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a spot welding machine structure to solve the problem mentioned in the background art that existing electric welding machines can only clamp and limit the spot welding object during use, and cannot adjust the spot welding position by displacement, resulting in low flexibility and inconvenience to users.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spot welding machine structure, comprising: a spot welding machine body, with front and rear displacement components installed on both sides of the spot welding machine body, a lateral displacement component installed above each of the two front and rear displacement components, a pushing component for adjusting the spot welding position installed at one end of one of the lateral displacement components, and a drive connector installed between the two front and rear displacement components.

[0007] Preferably, the lateral displacement assembly includes a lateral displacement guide platform, and limit frames are installed on both sides of the upper surface of the lateral displacement guide platform. The limit frames have a limit guide groove inside for the displacement of the steel plate.

[0008] Preferably, the pushing component includes an electrically operated telescopic rod installed on the end wall of the lateral displacement guide platform, and an electromagnet is installed at the telescopic end of the electrically operated telescopic rod.

[0009] Preferably, the front-to-back displacement assembly includes a front-to-back displacement platform, with slide rails provided on both sides of the front-to-back displacement platform, and guide sliders installed on both sides of the bottom of the transverse displacement guide platform, the guide sliders sliding on the slide rails.

[0010] Preferably, mounting grooves are provided on both sides of the interior of the front and rear displacement stage, and ball screws and guide rods are respectively installed inside the two mounting grooves. A screw slider is installed between the ball screw and the guide rod, and the screw slider is connected to the transverse displacement guide stage by bolts.

[0011] Preferably, the drive connector includes a first synchronous pulley and a second synchronous pulley, which are respectively mounted on one end of the two ball screws.

[0012] Preferably, a synchronous belt is installed between the first synchronous pulley and the second synchronous pulley, and a drive motor is installed at the front end of the first synchronous pulley.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) In this utility model, the metal plate is restricted and guided by the lateral displacement guide table. The metal plate is placed in the limiting guide groove of the two limiting frames. The limiting frames limit the metal plate. The electromagnet attracts the metal plate by generating magnetism through energization. During spot welding, the electric telescopic rod extends forward and pushes the metal plate forward in the limiting guide groove to the main body of the spot welding machine. During the spot welding process, as the electric telescopic rod extends and pushes, the spot welding position of the metal plate can be effectively adjusted. Finally, the metal plate is pushed into the limiting guide groove on the other side. The electromagnet is de-energized and demagnetized, making it convenient for the user to remove the spot-welded metal plate at this location. The above structure improves the lateral adjustment flexibility during the spot welding process of the metal plate and makes it convenient for the user to quickly remove the spot-welded metal plate.

[0014] (2) In this utility model, the drive motor drives the lead screw slider on one side to slide on the ball screw. During the displacement, it drives the upper transverse displacement guide to move, which is used to adjust the front and rear spot welding positions between the metal plate and the spot welding electrode. Through the setting of the guide slider and the slide rail, the transverse displacement guide can be made smoother and more stable during the front and rear displacement process. At the same time, the drive motor drives the first synchronous wheel to rotate, and through the connection of the first synchronous belt, it drives the second synchronous wheel to rotate, thereby driving the lead screw slider on the other front and rear displacement platform to perform synchronous displacement operation. The above structure effectively improves the front and rear adjustment capability during the spot welding process. Attached Figure Description

The metal plate is restricted and guided by the transverse displacement guide table 401. The metal plate is placed in the limiting guide groove 404 of the two limiting frames 403. The limiting frames 403 limit the metal plate. The electromagnet 502 attracts the metal plate by generating magnetism when energized. During spot welding, the electric telescopic rod 501 extends forward, pushing the metal plate forward in the limiting guide groove 404 to the spot welding machine body 1. During spot welding, the spot welding position of the metal plate can be effectively adjusted as the electric telescopic rod 501 extends and pushes. Finally, the metal plate is pushed into the limiting guide groove 404 on the other side. The electromagnet 502 is de-energized and demagnetized, making it convenient for the user to remove the spot-welded metal plate at this point.

[0018] Please see Figure 2 , Figure 3 , Figure 4 The front and rear displacement assembly 2 includes a front and rear displacement platform 201. Slide rails 206 are provided on both sides of the front and rear displacement platform 201. Guide sliders 402 are installed on both sides of the bottom of the transverse displacement guide platform 401. The guide sliders 402 slide on the slide rails 206.

Screw sliders 205 are installed between the ball screws 203 and guide rods 204. Screw sliders 205 are connected to the transverse displacement guide platform 401 by bolts. The drive connector 3 includes a first synchronous pulley 301 and a second synchronous pulley 302. The first synchronous pulley 301 and the second synchronous pulley 302 are respectively installed at one end of the two ball screws 203. A synchronous belt 303 is installed between the first synchronous pulley 301 and the second synchronous pulley 302. A drive motor 304 is installed at the front end of the first synchronous pulley 301. The drive motor 304 drives the lead screw slider 205 on one side to slide on the ball screw 203. During the displacement, it drives the upper transverse displacement guide 401 to move, which is used to adjust the front and rear spot welding positions between the metal plate and the spot welding electrode. Through the setting of the guide slider 402 and the slide rail 206, the transverse displacement guide 401 can be made smoother and more stable during the front and rear displacement. At the same time, the drive motor 304 drives the first synchronous pulley 301 to rotate. Through the connection of the first synchronous belt 303, it drives the second synchronous pulley 302 to rotate, thereby driving the lead screw slider 205 on the other front and rear displacement platform 201 to perform synchronous displacement operation. The above structure improves the flexibility of adjusting the metal plate during the spot welding process.
