A base plate is fixedly installed between two sets of support legs on the lower surface of the positioning plate. An installation groove is formed in the center of the upper surface of the base plate, and guide grooves are formed on both sides of the inner wall of the installation groove. Lifting components are provided at the lower ends of the support legs. The spot welding machine body is fixedly installed on the upper surface of the positioning plate. An adjustment component is provided on the base plate, and a protective component is provided on the adjustment component. The protective component is located at the upper end of the positioning plate. The adjustment component can adjust the position of the protective component. This utility model has the advantage that when the battery spot welding machine is placed after use, the operator can activate the adjustment component to adjust the position of the protective component, thereby achieving the advantage that the protective component can protect the spot welding machine body and improve the safety of the spot welding machine body during placement.

[0004] The existing technology has the following shortcomings: the existing spot welding device protection structure can only protect the spot welding machine when it is not working, and cannot protect the working area of ​​the spot welding machine during operation. This leaves the workers completely exposed in front of the working area of ​​the spot welding machine, which in turn affects the safety of the workers. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for battery spot welding. The protective plate can protect the working area of ​​the spot welding machine body, and the protective window and hand hole can facilitate the spot welding operation of the battery by the operator under protection, thus ensuring the safety of the spot welding process and solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for battery spot welding, comprising a spot welding machine body, and further comprising: A fixing mechanism located on the outside of the spot welding machine body and a protective mechanism located on the inside of the fixing mechanism; The fixing mechanism includes an operating table, a controller is fixedly installed on one outer wall of the operating table, a fixing plate is fixedly installed on one top side of the operating table, the top inner side of the fixing plate is fixedly connected to the spot welding machine body, and a clamping mechanism is provided on the top of the operating table. The protective mechanism includes two fixed shafts, which are rotatably mounted on both ends of the inner side of the fixed plate. Protective plates are fixedly sleeved on the outer sides of the two fixed shafts. Protective windows are fixedly installed at the joint positions of the two protective plates. Hand holes are opened at the joint positions of the two protective plates. A driving component is provided on the top of the two fixed shafts.

[0007] Preferably, a feeding plate is fixedly installed on the inner wall of the operating table, and the clamping mechanism includes a movable groove, which is formed on the bottom inner wall of the fixed plate.

[0008] Preferably, a hydraulic cylinder is fixedly installed at the middle position of the inner wall of the movable groove, and two piston rods of the hydraulic cylinder are fixedly installed with sliders, and the outer walls of the two sliders are slidably connected to the inner walls at both ends of the movable groove.

[0009] Preferably, a clamping plate is fixedly installed on one side of each of the two sliders, and the driving component includes two rotating worm gears fixedly sleeved on the outer side of the top of the fixed shaft. A bidirectional worm is rotatably installed on one side of the top of the fixed plate, and the two ends of the bidirectional worm mesh with the two rotating worm gears respectively.

[0010] Preferably, a servo motor is fixedly installed on the outer wall of one end of the fixed plate, and the servo motor is connected to one end of the bidirectional worm gear through an output shaft. An adjustment knob is rotatably installed on the outer wall of one side of the operating table.

[0011] Preferably, a snap-fit ​​plate is fixedly sleeved on the outside of the adjustment knob, and the snap-fit ​​plate is located on the outside of the joint position of the two protective plates.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1.

Through the meshing transmission between the bidirectional worm gear and the rotating worm wheel, the two fixed shafts rotate accordingly. This allows the two protective plates to protect the opening area inside the fixed plates. The protective window and handhole allow the operator to operate the spot welding machine body under protective conditions. This can protect the operator during the battery spot welding process and ensure the safety of the operator and the surrounding environment. 2.

[0020] This utility model provides, for example Figure 1 The protective device for battery spot welding shown includes a spot welding machine body 2, and further includes: The fixing mechanism 1 is located on the outside of the spot welding machine body 2, and the protective mechanism 3 is located on the inside of the fixing mechanism 1.

[0021] To ensure stable spot welding of the battery, such as Figure 1-3 As shown, the fixing mechanism 1 includes an operating table 101. A controller 102 is fixedly installed on the outer wall of one side of the operating table 101. A fixing plate 104 is fixedly installed on the top side of the operating table 101. The top inner side of the fixing plate 104 is fixedly connected to the spot welding machine body 2. A clamping mechanism is provided on the top of the operating table 101. The battery can be placed through the operating table 101. The controller 102 enables the clamping mechanism to clamp and fix the battery, so that the battery remains stable during the spot welding process. The fixing plate 104 can install and fix the spot welding machine body 2. The controller 102 enables the spot welding machine body 2 to perform spot welding operations on the battery.

[0022] To ensure that workers are properly protected during the spot welding process, such as Figure 1-5 As shown, the protective mechanism 3 includes two fixed shafts 301, which are rotatably mounted on both ends of the inner side of the fixed plate 104. Protective plates 302 are fixedly sleeved on the outer sides of the two fixed shafts 301. Protective windows 303 are fixedly installed at the joint of the two protective plates 302. Hand holes 304 are provided at the joint of the two protective plates 302. A driving component is provided on the top of the two fixed shafts 301. The controller 102 makes the driving component work, which in turn drives the two fixed shafts 301 to rotate. This allows the two protective plates 302 to seal the opening area between the operating table 101 and the fixed plate 104. The hand holes 304 allow the operator to stably operate the spot welding machine body 2 and stably perform spot welding operations. The protective windows 303 allow the operator to observe the working status of the spot welding machine body 2 and also provide protection.

[0023] To ensure the battery remains stable during the spot welding process, such as Figure 2-3 and Figure 5 As shown, a feeding plate 103 is fixedly installed on the inner wall of the operating table 101. The clamping mechanism includes a movable groove 105, which is opened on the bottom inner wall of the fixed plate 104. A hydraulic cylinder 106 is fixedly installed in the middle of the inner wall of the movable groove 105. Slider 107 is fixedly installed on both piston rods of the hydraulic cylinder 106. The outer walls of the two sliders 107 are slidably connected to the inner walls at both ends of the movable groove 105. A clamping plate 108 is fixedly installed on one side of each slider 107. The operating table 101 can install and fix the feeding plate 103. The movable groove 105 can install the hydraulic cylinder 106. The controller 102 causes the hydraulic cylinder 106 to extend or retract, so that the two sliders 107 can move relative to or away from each other along the inner wall of the movable groove 105. This allows the distance between the two clamping plates 108 to be adjusted. Batteries of different sizes can be clamped by the two clamping plates 108, so that the batteries remain stable during spot welding.

[0024] In order for the protective plate 302 to provide stable protection, such as Figure 2-5 As shown, the drive component includes two rotating worm gears 305 fixedly sleeved on the outer side of the top of the fixed shaft 301. A bidirectional worm gear 306 is rotatably mounted on one side of the top of the fixed plate 104, with both ends of the bidirectional worm gear 306 meshing with the two rotating worm gears 305 respectively. A servo motor 307 is fixedly mounted on the outer wall of one end of the fixed plate 104, and the servo motor 307 is connected to one end of the bidirectional worm gear 306 through an output shaft. An adjustment knob 109 is rotatably mounted on the outer wall of one side of the operating table 101, and a snap-fit ​​plate 110 is fixedly sleeved on the outer side of the adjustment knob 109. The snap-fit ​​plate 110 is located outside the joint position of the two protective plates 302. The fixed plate 104 can adjust the bidirectional worm gear 306 and the servo motor 307. For installation and fixation, the controller 102 drives the servo motor 307 to rotate the bidirectional worm gear 306. Through the meshing transmission between the bidirectional worm gear 306 and the rotating worm wheel 305, the two fixed shafts 301 rotate relative to each other, thereby allowing the protective plate 302 to seal the opening area between the operating table 101 and the fixed plate 104. At the same time, the rotation of the adjustment knob 109 can drive the snap-fit ​​plate 110 to rotate, so that the snap-fit ​​plate 110 can snap and limit the contact position of the two protective plates 302. In addition, both the servo motor 307 and the adjustment knob 109 are equipped with a self-locking structure, thereby allowing the protective plate 302 to stably play a protective role.

[0025] During the spot welding operation of the battery, the battery is placed on top of the unloading plate 103. Then, the controller 102 extends or retracts the hydraulic cylinder 106, which drives the two sliders 107 to move relative to or away from each other along the inner wall of the movable groove 105. This, in turn, moves the two clamping plates 108, allowing them to clamp and fix the battery. Then, the controller 102 drives the servo motor 307 to rotate the bidirectional worm gear 306. Through the meshing transmission between the bidirectional worm gear 306 and the two rotating worm wheels 305, the two fixed shafts 301 rotate relative to each other, thereby... The two protective plates 302 can be rotated to seal the opening between the fixed plate 104 and the operating table 101. Then, the operator can operate the spot welding machine body 2 through the handhole 304. The protective window 303 allows the operator to clearly observe the spot welding status of the spot welding machine body 2 on the battery, while also providing protection. This ensures that the operator is well protected during the battery spot welding process and guarantees the safety of the operator and the surrounding environment. This embodiment specifically solves the problem that the existing technology can only protect the spot welding machine when it is not in operation.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
