Description

Technical Field

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

[0002] In the field of battery technology, a battery pack assembly refers to connecting multiple battery cells together in series, parallel, or mixed connections, and integrating components such as a battery management system, thermal management system, casing, and connectors to form a complete battery module to meet the voltage, capacity, and power requirements of different application scenarios. In battery pack assembly, welding between batteries is a fundamental and critical operation, aiming to achieve reliable electrical connections between battery cells and ensure the stability and safety of the battery pack.

[0003] In existing battery pack assembly processes, the common practice is to place multiple individual cells on a support plate and use a spot welder to weld them together to complete the electrical connection between the cells. However, due to the wide variety of battery types and the differences in height between different types of batteries, especially when encountering long cylindrical cells, the height of the cells makes it impossible to fit them into the gap between the support plate and the spot welder, making welding impossible and increasing the complexity and inconvenience of the operation.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] Regarding the aforementioned problem that currently, multiple individual batteries are typically placed on a support plate and welded together using a spot welding machine, different battery types have different heights. Especially when encountering long, cylindrical batteries, their height makes it impossible to fit them into the gap between the support plate and the spot welding machine, thus hindering welding operations. The technical solution adopted by this invention to solve this problem is:

[0006] A battery spot welding machine with an adjustment function includes a device body. The device body includes a spot welding machine for welding batteries, a support plate located on one side of the spot welding machine for supporting the batteries, and an adjustment mechanism movably disposed between the spot welding machine and the support plate. The adjustment mechanism is provided with a drive mechanism for locking or unlocking the adjustment mechanism. The drive mechanism is rotatably connected to the adjustment mechanism. When the drive mechanism is rotated, the drive mechanism can move relative to the adjustment mechanism so that the support plate moves away from or closer to the spot welding machine.

[0007] Furthermore, the adjustment mechanism includes an adjustment slide, an adjustment groove disposed on one side of the adjustment slide, and an adjustment slider slidably connected to the adjustment groove. The spot welding machine is disposed on the side of the adjustment slide away from the adjustment groove, and the adjustment slider is detachably connected to the support plate.

[0008] Furthermore, the driving mechanism includes a driving handle and a driving screw connected to the driving handle. The driving screw is threadedly connected to the support plate and the adjusting slider, respectively. The adjusting slide groove is provided with a plurality of locking holes that cooperate with the driving screw.

[0009] Furthermore, the drive handle and the drive screw are integrally formed.

[0010] Furthermore, the support plate includes a first support plate arranged in a horizontal direction and a second connecting plate arranged in a vertical direction and connected to the first support plate, and the driving mechanism is located on the side of the second connecting plate away from the spot welding machine.

[0011] Furthermore, a number of reinforcing ribs are provided between the first support plate and the second connecting plate.

[0012] Furthermore, the drive handle includes a first touch surface, a second touch surface, and a third transition surface located between the first touch surface and the second touch surface, wherein the third transition surface is obliquely connected to the first touch surface and the second touch surface to form a rounded corner.

[0013] Furthermore, the adjusting slide includes a first slide surface extending along the height direction of the adjusting slide block, a second slide surface located on one side of the first slide surface, and a third slide surface located on the other side of the first slide surface. The second slide surface and the third slide surface extend obliquely from the first slide surface toward the adjusting slider.

[0014] Furthermore, the adjusting slider includes a first slider surface corresponding to the first slide groove surface, a second slider surface corresponding to the second slide groove surface, and a third slider surface corresponding to the third slide groove surface. The second slider surface and the third slider surface are both inclinedly connected to the first slider surface to form rounded corners.

[0015] Furthermore, the device body also includes a support base located at the end of the adjusting slide, the support base having a rectangular cross-section.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention provides an adjustment mechanism between a spot welding machine and a support plate. This mechanism has locked and unlocked states. When the user needs to adjust the relative distance between the support plate and the spot welding machine, a rotating drive mechanism moves relative to the adjustment mechanism, switching the adjustment mechanism from the locked to the unlocked state. At this point, the user can adjust the distance between the support plate and the spot welding machine to accommodate the height differences of different battery types. This effectively solves the problem that currently, multiple individual batteries are typically placed on a support plate and welded together using a spot welding machine. However, different battery types have different heights, especially long cylindrical batteries, which, due to their height characteristics, cannot be placed in the gap between the support plate and the spot welding machine, making welding impossible.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 6The battery spot welding machine with adjustment function shown includes a device body 1. The device body 1 includes a spot welding machine 2 for welding batteries, a support plate 3 located on one side of the spot welding machine 2 for supporting batteries, and an adjustment mechanism 4 movably disposed between the spot welding machine 2 and the support plate 3. The adjustment mechanism 4 is provided with a drive mechanism 5 for locking or unlocking the adjustment mechanism 4. The drive mechanism 5 is rotatably connected to the adjustment mechanism 4. When the drive mechanism 5 is rotated, the drive mechanism 5 can move relative to the adjustment mechanism 4 so that the support plate 3 moves away from or closer to the spot welding machine 2.

[0027] This invention provides an adjustment mechanism between a spot welding machine and a support plate. This mechanism has locked and unlocked states. When the user needs to adjust the relative distance between the support plate and the spot welding machine, a rotating drive mechanism moves relative to the adjustment mechanism, switching the adjustment mechanism from the locked to the unlocked state. At this point, the user can adjust the distance between the support plate and the spot welding machine to accommodate the height differences of different battery types. This effectively solves the problem that currently, multiple individual batteries are typically placed on a support plate and welded together using a spot welding machine. However, different battery types have different heights, especially long cylindrical batteries, which, due to their height characteristics, cannot be placed in the gap between the support plate and the spot welding machine, making welding impossible.

[0028] Furthermore, users can utilize the adjustment mechanism 4 to enable the spot welding machine 2 to adapt to various battery types and sizes, which helps to expand the application range of the spot welding machine 2 and reduces the cost and time required to replace equipment due to changes in battery type.

[0029] Optionally, in some embodiments, the adjusting mechanism 4 includes a first connecting pipe and a second connecting pipe, both arranged vertically. The first connecting pipe is sleeved on the outer wall of the second connecting pipe, located above the second connecting pipe and movable vertically relative to it. The spot welding machine 2 is connected to the first connecting pipe, and the support plate 3 is connected to the second connecting pipe. The first connecting pipe has a plurality of first locking holes spaced vertically, and the second connecting pipe has a plurality of second locking holes corresponding to the first locking holes. The driving mechanism 5 includes an adjusting screw and an adjusting nut respectively threadedly connected to the first and second locking holes. Under normal conditions, the adjusting screw is connected to both the first and second locking holes, thus fixing the distance between the spot welding machine 2 and the support plate 3. When the user needs to adjust the distance between the spot welding machine 2 and the support plate 3, the adjusting nut is rotated, which drives the adjusting screw to rotate and disengage from the first and second locking holes. At this time, the user can adjust the relative position between the first and second connecting pipes, thereby adjusting the distance between the spot welding machine 2 and the support plate 3. After adjusting to the appropriate position, the adjusting nut and the adjusting screw are rotated again so that the adjusting screw re-enters the first and second locking holes, locking the relative position between the spot welding machine 2 and the support plate 3.

[0030] Optionally, in some embodiments, the adjusting mechanism 4 includes a first connecting pipe and a second connecting rod threaded to the inner wall of the first connecting pipe. Both the first connecting pipe and the second connecting rod are arranged vertically, with the second connecting rod located above the first connecting pipe. The first connecting pipe is connected to the support plate 3, and the second connecting rod is connected to the spot welding machine 2. The driving mechanism 5 includes an adjusting handle connected to the second connecting rod. When the user needs to adjust the distance between the spot welding machine 2 and the support plate 3, the adjusting handle is rotated, and the second connecting rod rotates with the handle. The second connecting rod moves relative to the first connecting pipe in the vertical direction, thereby adjusting the distance between the spot welding machine 2 and the support plate 3.

[0031] Furthermore, as a preferred embodiment of this utility model, and not a limitation thereof, the adjusting mechanism 4 includes an adjusting slide 41, an adjusting groove 42 disposed on one side of the adjusting slide 41, and an adjusting slider 43 slidably connected to the adjusting groove 42. The spot welding machine 2 is disposed on the side of the adjusting slide 41 away from the adjusting groove 42, and the support plate 3 is disposed on the side of the adjusting slider 43 away from the adjusting groove 42. In the unlocked state, the adjusting slider 43 can move up and down along the extension direction of the adjusting groove 42, thereby adjusting the distance between the support plate 3 and the spot welding machine 2. The driving mechanism 5 includes a driving handle 51 and a driving screw connected to the driving handle 51. The rod 52 and the drive screw 52 are threadedly connected to the support plate 3 and the adjusting slider 43, respectively. The adjusting groove 42 is provided with several locking holes 420 that cooperate with the drive screw 52. When the relative positions of the support plate 3 and the spot welding machine 2 are properly adjusted, the user can rotate the drive handle 51. The drive handle 51 drives the drive screw 52 to rotate. Under the action of the threaded connection, the drive screw 52 moves relative to the support plate 3 and the spot welding machine 2 towards the adjusting groove 42. The drive screw 52 extends into the locking hole 420, and the adjusting mechanism 4 switches from the unlocked state to the locked state, thereby fixing the position of the support plate 3 and the spot welding machine 2.

[0032] like Figures 1 to 6 The adjustment mechanism 4 shown includes an adjustment slide 41, an adjustment groove 42 disposed on one side of the adjustment slide 41, and an adjustment slider 43 slidably connected to the adjustment groove 42. The spot welding machine 2 is disposed on the side of the adjustment slide 41 away from the adjustment groove 42. The adjustment slider 43 is detachably connected to the support plate 3.

[0033] Furthermore, the sliding connection between the adjusting slider 43 and the adjusting groove 42 allows the support plate 3 to move freely in the vertical direction, thereby easily adjusting the distance between it and the spot welding machine 2, so that the device body 1 can be adapted to batteries of different heights, which helps to increase the flexibility of operation.

[0034] Furthermore, the spot welding machine 2 is positioned on the side of the adjusting slide block 41 away from the adjusting slide groove 42, which helps to optimize the overall layout of the device, reduce space occupation, and make the overall structure of the device body 1 more compact.

[0035] Furthermore, the stable sliding of the adjusting slider 43 within the adjusting groove 42 helps ensure the stability of the support plate 3 during the adjustment process, effectively reducing safety risks caused by shaking or instability.

[0036] Furthermore, the support plate 3 can be quickly disassembled and replaced according to actual needs, so that users can replace the support plate 3 with a special one for batteries of different sizes or shapes, which helps to improve the versatility and flexibility of the device body 1.

[0037] Optionally, in some embodiments, the adjusting slider 43 and the support plate 3 may be connected by a snap-fit ​​connection.

[0038] Optionally, in some embodiments, the adjusting slider 43 and the support plate 3 may be connected by a slot connection.

[0039] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the adjusting slider 43 and the support plate 3 are connected by a threaded connection.

[0040] like Figures 1 to 6 The drive mechanism 5 shown includes a drive handle 51 and a drive screw 52 connected to the drive handle 51. The drive screw 52 is threadedly connected to the support plate 3 and the adjusting slider 43 respectively. The adjusting slide groove 42 is provided with a plurality of locking holes 420 that cooperate with the drive screw 52.

[0041] Furthermore, operators can easily control the rotation of the drive screw 52 by turning the drive handle 51, without the need for complex electrical equipment or automated control systems. During the adjustment process, operators can observe the relative positions of the support plate 3 and the spot welding machine 2 in real time according to the actual situation, and make adjustments at any time by turning the drive handle 51 to achieve position control of the support plate 3 and the spot welding machine 2.

[0042] Furthermore, once the relative positions of the support plate 3 and the spot welder 2 are properly adjusted, rotating the drive handle 51 causes the drive screw 52 to extend into the locking hole 420 on the adjusting slide 42, forming a mechanical lock. This provides reliable fixing force, ensuring that the positions of the support plate 3 and the spot welder 2 do not shift during battery welding, thus guaranteeing the stability and consistency of battery welding quality. Secondly, the adjusting slide 42 is equipped with several locking holes 420, allowing the support plate 3 and the spot welder 2 to be locked in multiple different positions. Users can flexibly select appropriate locking positions according to different welding process requirements and battery sizes, improving the versatility and applicability of the equipment.

[0043] Furthermore, the manual operation of the drive handle 51 is relatively safe, avoiding potential safety hazards such as electric shock and short circuits that may occur when using electrical equipment.

[0044] like Figures 1 to 6 The drive handle 51 and drive screw 52 shown are integrally formed;

[0045] Furthermore, the drive handle 51 and drive screw 52 are integrated components, avoiding the weak points at the connection points in the traditional split design. This helps to enhance the strength and rigidity of the overall structure. The one-piece molding design eliminates the risk of loosening or falling off the connection between the drive handle 51 and drive screw 52, ​​ensuring that stability and reliability are maintained even during frequent operation.

[0046] Furthermore, the one-piece molding configuration combines the drive handle 51 and the drive screw 52 into a single component, reducing the number of parts and assembly steps, and simplifying the production process.

[0047] Furthermore, the one-piece drive mechanism 5 reduces assembly errors and achieves higher transmission accuracy, which helps ensure the precision and stability of the support plate 3 during the adjustment process, improves the battery welding quality, and at the same time, the one-piece design also reduces the problem of decreased accuracy caused by component wear or loosening.

[0048] like Figures 1 to 6 The support plate 3 shown includes a first support plate 31 arranged in a horizontal direction and a second connecting plate 32 arranged in a vertical direction and connected to the first support plate 31. The driving mechanism 5 is located on the side of the second connecting plate 32 away from the spot welding machine 2.

[0049] Furthermore, the first support plate 31 is set in the horizontal direction to provide a stable support plane for the battery to be welded, ensuring that the battery is placed stably during the welding process. The second connecting plate 32 is set in the vertical direction, which increases the longitudinal space utilization efficiency of the equipment without increasing the horizontal area occupied too much. The drive mechanism 5 is located on the side of the second connecting plate 32 away from the spot welding machine 2, avoiding spatial conflict with the spot welding machine 2, so that the various components can be arranged in an orderly manner.

[0050] Furthermore, the drive mechanism 5 is located on the side of the second connecting plate 32 away from the spot welding machine 2, so that the appearance of the device body 1 is cleaner and more beautiful, while reducing the occupation of the operating area by the drive mechanism 5. At the same time, the drive mechanism 5 is located below the first support plate 31, so the user cannot see the setting of the drive mechanism 5 during normal use, further improving the aesthetics of the device body 1.

[0051] Furthermore, the first support plate 31 and the second connecting plate 32 are vertically connected, with an "L"-shaped cross-section. The "L"-shaped structure forms a more stable support system by vertically connecting the two plates, which helps to enhance the overall bending and torsional strength of the support plate 3, making it less prone to deformation or instability when subjected to large loads.

[0052] like Figures 1 to 6 A plurality of reinforcing ribs 33 are provided between the first support plate 31 and the second connecting plate 32 shown;

[0053] Furthermore, the reinforcing rib 33, as an important structural reinforcement, can significantly improve the overall stiffness of the support plate 3. By transferring and dispersing the load acting on the support plate 3, the reinforcing rib 33 enables the entire structure to better resist deformation, thereby maintaining its stability.

[0054] Furthermore, the reinforcement rib 33 is provided so that the support plate 3 can withstand a greater load. By providing the reinforcement rib 33, it is beneficial to ensure that the support plate 3 will not be damaged or fail during long-term use.

[0055] Optionally, in some embodiments, the reinforcing rib 33 is rectangular in shape. The rectangular reinforcing rib 33 is vertically connected between the first support plate 31 and the second connecting plate 32, and the plate surface of the reinforcing rib 33 is perpendicular to the intersection line of the first support plate 31 and the second connecting plate 32. The rectangular reinforcing rib 33 can be fixed between the first support plate 31 and the second connecting plate 32 by welding or other connection methods. The structure is simple and easy to manufacture and install.

[0056] Optionally, in some embodiments, the reinforcing rib 33 is arc-shaped, and the two ends of the arc-shaped reinforcing rib 33 are respectively connected to the first support plate 31 and the second connecting plate 32. The arc-shaped structure can better adapt to the deformation of the support plate 3 under stress, making the stress distribution more uniform. Compared with straight ribs, arc-shaped ribs can provide greater elastic deformation capacity in a smaller space, reduce stress concentration, and improve the service life of the support plate 3.

[0057] Optionally, in some embodiments, the cross-section of the reinforcing rib 33 is triangular. One side of the reinforcing rib 33 is connected to the first support plate 31, and the other side is connected to the second connecting plate 32. The hypotenuse serves to strengthen the support. The triangular reinforcing rib 33 has good mechanical properties, can effectively disperse stress, improve the load-bearing capacity of the support plate 3, and the triangular structure itself has stability, which can better resist the action of external forces and reduce the deformation of the support plate 3 under stress.

[0058] like Figures 1 to 6 The drive handle 51 shown includes a first touch surface 511, a second touch surface 512, and a third transition surface 513 located between the first touch surface 511 and the second touch surface 512. The third transition surface 513 is obliquely connected to the first touch surface 511 and the second touch surface 512 to form rounded corners.

[0059] Furthermore, the rounded corners allow for a smoother transition of the fingers when the user grips and rotates the drive handle 51, reducing friction and discomfort caused by sharp edges, making operation easier and more natural, and improving the user experience.

[0060] Furthermore, rounded corners not only improve the user's operating experience, but also enhance the structural strength of the drive handle 51 to a certain extent. By forming a smooth transition surface through the inclined connection, the possibility of stress concentration is reduced, making the drive handle 51 more stable when subjected to external forces.

[0061] Furthermore, the rounded corners make the lines of the drive handle 51 smoother, enhancing the overall aesthetics of the device. The rounded corner transition makes the surface of the drive handle 51 feel softer, increasing the high-end feel of the device.

[0062] like Figures 1 to 6 The adjustable slide 42 shown includes a first slide surface 421 extending along the height direction of the adjustable slide block 41, a second slide surface 422 located on one side of the first slide surface 421, and a third slide surface 423 located on the other side of the first slide surface 421. The second slide surface 422 and the third slide surface 423 extend obliquely from the first slide surface 421 toward the adjustable slider 43, respectively.

[0063] Furthermore, by setting the inclined second slide surface 422 and the third slide surface 423, a more stable guiding effect can be provided for the adjusting slider 43, reducing wobbling and offset during the sliding process, thereby improving the accuracy of the adjustment process.

[0064] Furthermore, the inclined arrangement of the second slide surface 422 and the third slide surface 423 can reduce the impact force on the adjusting slider 43 during the sliding process, thereby reducing noise and vibration and improving the stability of equipment operation.

[0065] like Figures 1 to 6 The adjustable slider 43 shown includes a first slider surface 431 corresponding to the first slide groove surface 421, a second slider surface 432 corresponding to the second slide groove surface 422, and a third slider surface 433 corresponding to the third slide groove surface 423. The second slider surface 432 and the third slider surface 433 are both inclinedly connected to the first slider surface 431 to form rounded corners.

[0066] Furthermore, the rounded corners are designed to make the sliding of the adjusting slider 43 in the adjusting groove 42 smoother. When the adjusting slider 43 moves along the adjusting groove 42, the rounded corners can reduce the friction and resistance between the adjusting slider 43 and the adjusting groove 42, making the sliding action smoother and more stable.

[0067] Furthermore, the rounded corners help reduce the direct contact area between the adjusting slider 43 and the adjusting groove 42, thereby reducing wear caused by friction, extending the service life of the adjusting slider 43 and the adjusting groove 42, and reducing equipment failure and maintenance costs caused by wear.

[0068] Furthermore, by forming rounded corners through inclined connections, the structural strength of the adjusting slider 43 is enhanced. The rounded corners can disperse the stress on the adjusting slider 43 during movement, reduce stress concentration, and thus improve the deformation resistance and damage resistance of the adjusting slider 43.

[0069] like Figures 1 to 6 The device body 1 shown also includes a support base 6 located at the end of the adjusting slide 41, and the cross-section of the support base 6 is rectangular;

[0070] Furthermore, the rectangular cross-section support base 6 provides a larger support area for the device body 1 compared to other shapes such as circles and triangles. When the device is working, whether it is subjected to vertical gravity or horizontal external force, the larger support area can make the contact between the device and the support surface more stable, reducing the risk of the device tipping over or shaking due to uneven force.

[0071] Furthermore, the geometric characteristics of the rectangular structure enable the support base 6 to evenly distribute the weight of the device body 1 onto the support surface. When the device is under load, the four sides and four corners of the rectangular base can share the pressure, avoiding excessive local pressure.

[0072] Optionally, the support base 6 can be welded to the end of the adjusting slide 41.

[0073] Optionally, the ends of the support base 6 and the adjusting slide 41 can be connected by threaded connection, snap-fit ​​connection, slot connection, or other connection methods.

[0074] The implementation method of Example 1 is as follows:

[0075] A battery spot welding machine with an adjustable function includes a device body 1. The device body 1 includes a spot welding machine 2 for welding batteries, a support plate 3 located on one side of the spot welding machine 2 for supporting the batteries, and an adjusting mechanism 4 movably disposed between the spot welding machine 2 and the support plate 3. The adjusting mechanism 4 is provided with a drive mechanism 5 for locking or unlocking the adjusting mechanism 4. The adjusting mechanism 4 includes an adjusting slide 41, an adjusting groove 42 located on one side of the adjusting slide 41, and an adjusting slider 43 slidably connected to the adjusting groove 42. The spot welding machine 2 is located on the side of the adjusting slide 41 away from the adjusting groove 42. The adjusting slider 43 is detachably connected to the support plate 3. The drive mechanism 5 includes a drive handle 51 and a drive screw 52 connected to the drive handle 51. The drive screw 52 is threadedly connected to the support plate 3 and the adjusting slider 43 respectively. The adjusting groove 42 is provided with a plurality of locking holes 420 that cooperate with the drive screw 52. Under normal conditions, the drive screw 52 extends into the locking holes 420. At this time, the adjustment mechanism 4 is in the locked state. When the user needs to adjust the relative position of the spot welding machine 2 and the support plate 3, the user rotates the drive handle 51. The drive handle 51 drives the drive screw 52 to rotate. Under the action of the threaded connection, the drive screw 52 moves relative to the support plate 3 and the adjustment slider 43. The drive screw 52 disengages from the locking hole 420, and the adjustment mechanism 4 switches from the locked state to the unlocked state. At this time, the adjustment slider 43 can move up and down along the extension direction of the adjustment groove 42, thereby adjusting the distance between the support plate 3 and the spot welding machine 2. After the relative position of the support plate 3 and the spot welding machine 2 is adjusted properly, the user rotates the drive handle 51 in the opposite direction. The drive handle 51 drives the drive screw 52 to rotate. Under the action of the threaded connection, the drive screw 52 moves relative to the support plate 3 and the spot welding machine 2 towards the adjustment groove 42. The drive screw 52 extends into the locking hole 420, and the adjustment mechanism 4 switches from the unlocked state to the locked state, thereby fixing the position of the support plate 3 and the spot welding machine 2.

[0076] The implementation method of Example 2 is as follows:

[0077] The difference between Example 2 and Example 1 is that: the adjusting mechanism 4 includes a first connecting pipe and a second connecting pipe, both of which are arranged vertically. The first connecting pipe is sleeved on the outer wall of the second connecting pipe, and is located above the second connecting pipe and can move vertically relative to it. The spot welding machine 2 is connected to the first connecting pipe, and the support plate 3 is connected to the second connecting pipe. The first connecting pipe has several first locking holes spaced vertically, and the second connecting pipe has several second locking holes corresponding to the first locking holes. The driving mechanism 5 includes adjusting screws threadedly connected to the first and second locking holes respectively, and adjusting... Under normal conditions, the adjusting screw is connected to both the first and second locking holes, thus fixing the distance between the spot welding machine 2 and the support plate 3. When the user needs to adjust the distance between the spot welding machine 2 and the support plate 3, the adjusting nut is rotated, which drives the adjusting screw to rotate and disengage from the first and second locking holes. At this time, the user can adjust the relative position between the first and second connecting pipes, thereby adjusting the distance between the spot welding machine 2 and the support plate 3. After adjusting to the appropriate position, the adjusting nut and the adjusting screw are rotated again so that the adjusting screw re-enters the first and second locking holes, locking the relative position between the spot welding machine 2 and the support plate 3.

[0078] The implementation method of Example 3 is as follows:

[0079] The difference between Embodiment 3 and Embodiment 1 is that: the adjusting mechanism 4 includes a first connecting pipe and a second connecting rod threaded to the inner wall of the first connecting pipe. Both the first connecting pipe and the second connecting rod are arranged vertically, with the second connecting rod located above the first connecting pipe. The first connecting pipe is connected to the support plate 3, and the second connecting rod is connected to the spot welding machine 2. The driving mechanism 5 includes an adjusting handle connected to the second connecting rod. When the user needs to adjust the distance between the spot welding machine 2 and the support plate 3, the adjusting handle is rotated, and the second connecting rod rotates with the handle. The second connecting rod moves relative to the first connecting pipe in the vertical direction, thereby adjusting the distance between the spot welding machine 2 and the support plate 3.
