Description

Technical Field

[0001] The invention relates to the technical field of welding positioning, and in particular to a welding positioning device and method. Background Art

[0002] When welding the wire harness to the terminal, two relatively arranged limit push blocks are required to limit the welding width, so as to ensure a better welding effect between the terminal and the wire harness; in order to avoid the influence of the small amplitude vibration of the terminal during the welding process on the limit push blocks, the distance between the limit push blocks is located above the terminals; and in order to avoid interference between the welding head and the limit push blocks, the distance between the welding head and the limit push blocks in the horizontal direction needs to be adjusted.

[0003] However, since the distance between the limit push block and the welding head is usually adjusted by a cylinder, that is, the position of the limit push block is directly adjusted by the linear motion of the cylinder, it is necessary to manually adjust the nut repeatedly to adjust the extension distance of the cylinder's piston rod. The adjustment process is cumbersome, laborious and time-consuming, and the accuracy of the position of the limit push block cannot be guaranteed.

[0004] In view of the above problems, a welding positioning device and method are urgently needed to solve the above problems. Summary of the invention

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] Welding positioning device, comprising:

[0018] As an optional solution, the welding positioning device further includes:

[0019] The second adjustment component includes a second driving member, which drives the limit push block to move downward along the Z axis until it touches the first workpiece. After the limit push block touches the first workpiece, the second driving member drives the limit push block to move upward along the Z axis away from the first workpiece by a second preset distance.

[0020] As an optional solution, the second adjustment assembly further includes a second adjustment member, and the second driving member is connected to the second adjustment member so as to drive the limiting push block to move along the Z axis through the second adjustment member.

[0021] As an optional solution, the second adjusting member includes:

[0022] a lower wedge block, wherein the lower wedge block is slidably disposed on the base with the inclined surface facing upward; and

[0023] An upper wedge block, wherein the upper wedge block is stacked on the lower wedge block, the inclined surface of the upper wedge block is slidably connected to the inclined surface of the lower wedge block, the upper wedge block is connected to the supporting plate, and the second output end of the second driving member is connected to the lower wedge block, which can drive the lower wedge block to move along the Y axis, so as to drive the supporting plate to move along the Z axis through the upper wedge block.

The distance between the top end surface of the first workpiece and the bottom end surface of the limit push block on the Z axis is the second preset distance.

[0030] The beneficial effects of the present invention are:

[0031] By setting a first adjustment component including a first driving member and a limit push block, when it is necessary to adjust the spacing between the limit push block and the welding head on the Y-axis, the first driving member is first driven to drive the limit push block to move along the Y-axis until the first driving member stops working when the limit push block touches the welding head, thereby accurately finding the first touch position between the limit push block and the welding head; when the limit push block touches the welding head, the first driving member drives the limit push block to move a first preset distance away from the welding head on the Y-axis from the first touch position and then stops working, so that the spacing between the welding head and the limit push block on the Y-axis is the first preset distance, thereby accurately adjusting the spacing between the limit push block and the welding head; the spacing between the limit push block and the welding head is adjusted by the above-mentioned method of first touching and then moving away, and the adjustment method is automated, time-saving and labor-saving, and the position of the limit push block can be accurately adjusted to ensure that the spacing between the limit push block and the welding head is relatively accurate, thereby better avoiding interference between the limit push block and the welding head.

[0045] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0046] Embodiment 1

[0047] like Figures 1 to 3As shown, a welding positioning device is proposed in this embodiment, which can accurately locate the first preset distance between the limit push block 35 and the welding head 20, and can accurately locate the second preset distance between the limit push block 35 and the first workpiece, so as to ensure the welding quality between the first workpiece and the second workpiece 10. Among them, the first workpiece is located between two relatively set limit push blocks 35, and the first workpiece is located at one end of the second workpiece 10, and the welding head 20 is located above the first workpiece. Among them, the first workpiece can be specifically a terminal, and the second workpiece 10 can be specifically a wiring harness, so that the wiring harness can be welded to the terminal through the welding head 20. The specific structure of the first workpiece and the second workpiece 10 is not limited here.

[0048] Specifically, Figures 1 to 3 As shown, the welding positioning device includes a base 1 and a first adjustment component 3; wherein a supporting plate 2 is arranged on the base 1; two first adjustment components 3 are arranged in parallel along the Y-axis, the first adjustment components 3 are arranged on the supporting plate 2, and the second workpiece 10 is arranged between the two first adjustment components 3 along the X-axis; the first adjustment component 3 includes a first driving member 31 and the above-mentioned limiting push block 35, the limiting push blocks 35 in the two first adjustment components 3 are arranged relatively, and the fixed end of the first driving member 31 is arranged on the supporting plate 2; the first driving member 31 is used to drive the limiting push block 35 to move along the Y-axis until it touches the welding head 20, when the limiting push block 35 touches the welding head 20, the first driving member 31 drives the limiting push block 35 from the first touch position with the welding head 20 along the Y-axis away from the welding head 20 by a first preset distance, thereby adjusting the spacing of the limiting push block 35 relative to the welding head 20 on the Y-axis. Among them, the first touch position is specifically the position where the limit push block 35 just touches the welding head 20; and the first workpiece is suspended on the supporting plate 2 through a positioning member, and the positioning member is not connected to the supporting plate 2, that is, the movement of the supporting plate 2 on the Z axis will not affect the first workpiece, so that the first workpiece always remains stationary during the entire process.

[0049] Specifically, when the spacing between the limit push block 35 and the welding head 20 needs to be adjusted, the first driving member 31 drives the limit push block 35 to move along the Y axis until the limit push block 35 touches the welding head 20, and the first driving member 31 stops working, so that the first touching position between the limit push block 35 and the welding head 20 can be accurately found; then the first driving member 31 drives the limit push block 35 to move away from the welding head 20 on the Y axis by a first preset distance, and the first driving member 31 stops working at this time, so that the spacing between the welding head 20 and the limit push block 35 on the Y axis is the first preset distance, so that the spacing between the limit push block 35 and the welding head 20 can be accurately adjusted. In this embodiment, the first preset distance is specifically 5 wires, and the specific value of the first preset distance is not limited here, and needs to be determined according to specific working conditions and actual welding requirements.

[0050] Compared with the prior art, the welding positioning device in this embodiment changes the adjustment method of the limit push block 35; by adjusting the distance between the limit push block 35 and the welding head 20 by first touching and then moving away, the adjustment method is automated, saving time and effort, and can accurately adjust the position of the limit push block 35 to ensure that the distance between the limit push block 35 and the welding head 20 is relatively accurate, thereby better avoiding interference between the limit push block 35 and the welding head 20.

[0051] Furthermore, the first driving member 31 includes a first driving structure and a first calculating element; wherein the first driving structure is used to drive the limit push block 35 to move along the Y axis; and the first calculating element is used to calculate the distance that the limit push block 35 needs to move to touch the welding head 20, so as to ensure that the limit push block 35 touches the welding head 20. In this embodiment, the first calculating element can be a common calculating module in the prior art.

[0052] Preferably, the first driving structure can be specifically a first servo electric cylinder, and the first servo electric cylinder has a first servo torque working mode and a first servo displacement working mode; when it is necessary to accurately find the first contact position between the limit push block 35 and the welding head 20, the first servo electric cylinder is in the first servo torque working mode; when it is necessary to ensure that the moving distance of the limit push block 35 relative to the welding head 20 is relatively accurate, the first servo electric cylinder is in the first servo torque working mode, so as to ensure that the spacing between the limit push block 35 and the welding head 20 can be accurately adjusted. In other embodiments, the first driving structure can also be other structures, or the first driving structure can be used in conjunction with other limit structures, as long as it can ensure that the spacing between the limit push block 35 and the welding head 20 can be accurately adjusted. Here, the specific structure of the first driving structure is not limited.

[0053] Specifically, Figure 2 and Figure 3 As shown, the first adjustment assembly 3 also includes a first adjustment member 32, the driving end of the first driving member 31 is connected to the first adjustment member 32, the first adjustment member 32 is slidably disposed on the bearing plate 2, and the limit push block 35 is slidably connected to the first adjustment member 32; the first driving member 31 is used to drive the first adjustment member 32 to move along the X axis, so as to drive the limit push block 35 to move along the Y axis. In this embodiment, the first adjustment member 32 can be specifically a horizontal wedge block.

[0054] Furthermore, if Figures 1 to 3As shown, the first adjustment component 3 also includes a positioning main block 33 and a positioning sub-block 34; wherein the positioning main block 33 is fixedly mounted on the carrier plate 2, the first adjustment member 32 is slidably arranged inside the positioning main block 33 along the X-axis, the fixed end of the first driving member 31 is located at one end of the positioning main block 33, and the first output end 311 of the first driving member 31 passes through the positioning main block 33 along the X-axis and is fixedly connected to the first adjustment member 32; the positioning sub-block 34 is slidably arranged on one side of the first adjustment member 32 along the Y-axis, a first wedge surface is arranged on the first adjustment member 32, a second wedge surface is arranged at one end of the positioning sub-block 34, the first wedge surface is slidably connected to the second wedge surface, and the other end of the positioning sub-block 34 is fixedly connected to the limit push block 35, that is, the first wedge surface and the second wedge surface are connected by a horizontal sliding structure, and the horizontal sliding structure can be, for example, a slide rail slider, which is not limited here. wherein the first output end 311 is specifically a first telescopic rod.

[0055] Specifically, when the first driving member 31 is working, the first output end 311 drives the first adjusting member 32 to slide along the X-axis inside the main positioning block 33. Due to the sliding connection between the first wedge surface of the first adjusting member 32 and the second wedge surface of the positioning block 34, the positioning block 34 can be driven to move on the Y-axis through the movement of the first adjusting member 32, thereby driving the limit push block 35 to move on the Y-axis, so that the two limit push blocks 35 are close to or away from each other, and the spacing of the limit push block 35 relative to the welding head 20 can be adjusted.

[0056] Furthermore, if Figure 3 As shown, a sliding groove 331 is provided inside the positioning main block 33, and the first adjusting member 32 is slidably provided in the sliding groove 331, so as to ensure the smooth sliding of the first adjusting member 32 inside the positioning main block 33; and when the first output end 311 drives the first adjusting member 32 to return, the sliding groove 331 can provide a guide for the return of the first adjusting member 32, so as to ensure the rapid return of the two first adjusting members 32. In this embodiment, the shape of the sliding groove 331 does not need to be exactly the same as that of the first adjusting member 32, as long as the shape of the sliding groove 331 matches that of the first adjusting member 32, and no specific limitation is made here.

[0057] Specifically, Figure 1 and Figure 2 As shown, the first adjustment assembly 3 further includes a limiter 36 , which is disposed on one side of the main positioning block 33 and connected to the first adjustment member 32 , and is used to limit the sliding of the first adjustment member 32 .

[0058] Specifically, if Figure 1 and Figure 2As shown, the limiting member 36 includes a clamp 361 and a clamp rod 362, the clamp 361 is installed on the end of the positioning main block 33 where the first driving member 31 is not provided; one end of the clamp rod 362 is fixedly connected to the first adjusting member 32, and the other end of the clamp rod 362 passes through the clamp 361; when the first adjusting member 32 moves to a suitable position along the X-axis, the clamp 361 is started so that the clamp rod 362 can be clamped by the clamp 361, so as to limit the first adjusting member 32 by the clamp rod 362, thereby limiting the position change of the first adjusting member 32 when subjected to unexpected force, thereby ensuring that the first adjusting member 32 can be stably fixed at this position.

[0059] During the welding process, in order to enable resonance between the welding head 20 and the first workpiece, thereby ensuring the welding effect, it is necessary to adjust the distance between the bottom end surface of the limit push block 35 and the top end surface of the first workpiece on the Z axis; for this purpose, in this embodiment, Figure 1 and Figure 5 As shown, the welding positioning device also includes a second adjustment component 4, which includes a second driving member 41. The second driving member 41 is used to drive the limit push block 35 to move downward along the Z axis until it touches the first workpiece. When the limit push block 35 touches the first workpiece, the second driving member 41 drives the limit push block 35 to move upward along the Z axis away from the first workpiece by a second preset distance from the second touch position, thereby adjusting the spacing of the limit push block 35 relative to the first workpiece on the Z axis. The second touch position is specifically the position where the limit push block 35 just touches the first workpiece.

[0060] Specifically, when it is necessary to adjust the spacing between the limit push block 35 and the first workpiece, the second driving member 41 drives the limit push block 35 to move along the Z axis until the limit push block 35 touches the first workpiece, and the second driving member 41 stops working, so that the second touching position between the limit push block 35 and the first workpiece can be accurately found; then the second driving member 41 drives the limit push block 35 to move away from the first workpiece on the Z axis by a second preset distance, and the second driving member 41 stops working at this time, so that the spacing between the first workpiece and the limit push block 35 on the Z axis is the second preset distance, so that the spacing between the limit push block 35 and the first workpiece can be accurately adjusted. In this embodiment, the second preset distance is specifically 5 wires, and the specific value of the second preset distance is not limited here, and needs to be determined according to specific working conditions and actual welding requirements.

[0061] By adjusting the distance between the limit push block 35 and the first workpiece by first touching and then moving away, the adjustment method is automated, saving time and effort, and can accurately adjust the position of the limit push block 35 to ensure that the distance between the limit push block 35 and the first workpiece is relatively accurate, thereby better ensuring resonance between the welding head 20 and the first workpiece.

[0062] Furthermore, the second driving member 41 includes a second driving structure and a second calculating element; wherein the second driving structure is used to drive the limit push block 35 to move along the Z axis; the second calculating element is used to calculate the distance that the limit push block 35 needs to move to touch the first workpiece, so as to ensure that the limit push block 35 touches the first workpiece. In this embodiment, the second calculating element can use a common calculating module in the prior art.

[0063] Preferably, the second driving structure can be specifically a second servo electric cylinder, and the second servo electric cylinder has a second servo torque working mode and a second servo displacement working mode; when it is necessary to accurately find the second contact position between the limit push block 35 and the first workpiece, the second servo electric cylinder is in the second servo torque working mode; when it is necessary to ensure that the moving distance of the limit push block 35 relative to the first workpiece is relatively accurate, the second servo electric cylinder is in the second servo torque working mode, so as to ensure that the distance between the limit push block 35 and the first workpiece can be accurately adjusted. In other embodiments, the second driving structure can also be other structures, or the second driving structure can be used in conjunction with other limit structures, as long as it can ensure that the distance between the limit push block 35 and the first workpiece can be accurately adjusted. Here, the specific structure of the second driving structure is not limited.

[0064] Furthermore, if Figure 4 As shown, the second adjustment component 4 also includes a second adjustment member 44, the second driving member 41 is connected to the second adjustment member 44, the second adjustment member 44 is connected to the supporting plate 2, and the second driving member 41 is used to drive the second adjustment member 44 to move, so as to drive the supporting plate 2 and the first adjustment component 3 thereon to move along the Z axis through the second adjustment member 44, so as to drive the limiting push block 35 to move along the Z axis.

[0065] Moreover, in this embodiment, a second driving member 41 and a second adjusting member 44 are provided to drive the supporting plate 2 and the first adjusting component 3 thereon to move on the Z-axis, thereby realizing the lifting and lowering adjustment function of the limit push block 35 on the Z-axis; compared with the current limit push block 35 which has no lifting and lowering adjustment function, the Z-axis lifting and lowering adjustment of the limit push block 35 is added, so that the position adjustment flexibility of the limit push block 35 is better, and the adjustment method is simpler and more convenient.

[0066] Furthermore, if Figure 4As shown, the second adjusting member 44 includes an upper wedge block 441 and a lower wedge block 442, the lower wedge block 442 is slidably arranged on the base 1 with the inclined surface facing upward, the upper wedge block 441 is stacked on the lower wedge block 442, and the inclined surfaces of the upper wedge block 441 and the lower wedge block 442 abut against each other and are slidably connected, the upper wedge block 441 is fixedly connected to the bottom end surface of the supporting plate 2, the fixed end of the second driving member 41 is arranged on the base 1, and the second output end of the second driving member 41 is connected to the lower wedge block 442 to drive the lower wedge block 442 to move along the Y axis. Since the inclined surfaces of the upper wedge block 441 and the lower wedge block 442 are slidably connected, the upper wedge block 441 can be driven to move along the Z axis through the movement of the lower wedge block 442, thereby driving the supporting plate 2 and the first adjusting component 3 thereon to move along the Z axis. Among them, the second output end 411 is specifically a second telescopic rod; and an inclined sliding connection structure is provided between the upper wedge block 441 and the lower wedge block 442 to ensure the sliding guidance and stability between the upper wedge block 441 and the lower wedge block 442; the inclined sliding connection structure can be, for example, an inclined guide block and an inclined guide rail, which is not limited here.

[0067] Specifically, Figure 5 As shown, the second adjustment assembly 4 also includes a synchronization plate 42 and an elastic member 43; wherein the synchronization plate 42 is fixedly connected to the bottom end surface of the carrier plate 2; the elastic member 43 extends along the Z axis, one end of the elastic member 43 is connected to the synchronization plate 42, and the other end of the elastic member 43 is connected to the base 1. In this embodiment, the elastic member 43 is specifically a tension spring. Among them, a vertical sliding structure is provided between the synchronization plate 42 and the base 1 to ensure the guidance and stability of the synchronization plate 42 and the carrier plate 2 moving on the Z axis; the vertical sliding structure can be, for example, a guide block guide rail, which is not limited here.

[0068] Specifically, when the lower wedge block 442 drives the upper wedge block 441 and the supporting plate 2 to move upward along the Z axis, the supporting plate 2 drives the synchronous plate 42 to rise so that the elastic member 43 is stretched; when the supporting plate 2 moves downward along the Z axis, the synchronous plate 42 and the supporting plate 2 can smoothly descend under the elastic tension of the elastic member 43, thereby ensuring that the supporting plate 2 can return to its original position relatively smoothly and quickly.

[0069] Embodiment 2

[0070] This embodiment proposes a welding positioning method, based on the welding positioning device in the first embodiment, adjusting the distance between the limit push block 35 and the welding head 20, and the limit push block 35 and the first workpiece; Figure 6 As shown, the specific steps include:

[0071] When adjusting the distance between the limit push block 35 and the welding head 20:

[0072] S1: The first driving member 31 is operated, and the first driving member 31 drives the first adjusting member 32 to move along the X-axis, so as to drive the limiting push block 35 to move along the Y-axis, until the limiting push block 35 touches the welding head 20, and the first driving member 31 stops working;

[0073] S2: After the limit push block 35 touches the welding head 20, the first driving member 31 drives the first adjusting member 32 to move along the X-axis to drive the limit push block 35 to move a first preset distance away from the welding head 20 from the first touch position on the Y-axis. At this time, the first driving member 31 stops working, so that the distance between the welding head 20 and the limit push block 35 on the Y-axis is the first preset distance.

[0074] Further, when adjusting the distance between the limiting push block 35 and the first workpiece, as Figure 6 As shown, the welding positioning method also includes the following steps:

[0075] S3: The second driving member 41 drives the second adjusting member 44 to move along the Y axis, and at the same time, the second adjusting member 44 moves along the Z axis, so as to drive the supporting plate 2 and the limiting push block 35 to move downward along the Z axis as a whole through the second adjusting member 44, until the bottom end surface of the limiting push block 35 touches the top end surface of the first workpiece, and the second driving member 41 stops working;

[0076] S4: After the limit push block 35 touches the first workpiece, the second driving member 41 drives the second adjusting member 44 to move along the Y-axis, and at the same time makes the second adjusting member 44 move along the Z-axis, so as to drive the supporting plate 2 and the limit push block 35 as a whole to move upward along the Z-axis away from the first workpiece from the second touch position to a second preset distance. At this time, the second driving member 41 stops working, so that the distance between the top end surface of the first workpiece and the bottom end surface of the limit push block 35 is the second preset distance.

[0077] Through the above-mentioned adjustment process of first touching and then moving away, the accurate touching position of the limit push block 35 and the accurate return distance of the limit push block 35 can be guaranteed, thereby ensuring that the distance between the welding head 20 and the limit push block 35 on the Y axis is the first preset distance, and the distance between the top end surface of the first workpiece and the bottom end surface of the limit push block 35 on the Z axis is the second preset distance; the entire adjustment process does not require manual participation, has a high degree of automation, and saves time and effort.

[0078] Furthermore, before each welding between the first workpiece and the second workpiece 10, the above steps S1-S4 need to be repeated to adjust the distance between the limit push block 35 and the welding head 20, and between the limit push block 35 and the first workpiece; when the welding head 20 is worn, the limit push block 35 can still move the first preset distance in the direction away from the welding head 20 after touching the welding head 20, so as to ensure that the distance between the welding head 20 and the limit push block 35 will not change due to the wear of the welding head 20, and ensure that the distance between the welding head 20 and the limit push block 35 always remains at the first preset distance, thereby realizing adaptive adjustment of the distance between the welding head 20 and the limit push block 35, which is equivalent to compensating for the wear of the welding head 20, thereby avoiding the problem that the distance between the welding head 20 and the limit push block 35 becomes larger due to the wear of the welding head 20, thereby causing the welding material to flow out from the enlarged distance and resulting in poor welding effect, so as to ensure the welding width between the first workpiece and the second workpiece 10, so as to achieve better welding quality.

[0079] Furthermore, when the thickness of the first workpiece changes, the limit push block 35 can still move the second preset distance in the direction away from the first workpiece after touching the first workpiece, thereby ensuring that the distance between the first workpiece and the limit push block 35 will not change due to the change in the thickness of the first workpiece, ensuring that the distance between the first workpiece and the limit push block 35 always remains at the second preset distance, realizing adaptive adjustment of the distance between the first workpiece and the limit push block 35, which is equivalent to compensating for the distance change of the thickness of the first workpiece, thereby avoiding the distance between the first workpiece and the limit push block 35 from becoming larger or smaller due to the change in the thickness of the first workpiece, thereby ensuring better welding quality; and ensuring that the vibration of the first workpiece during the welding process will not interfere with the limit push block 35.

[0080] Furthermore, if Figure 6 As shown, before step S1, the following step S0 is also included: the second driving member 41 is operated, and the second driving member 41 drives the second adjusting member 44 to move, so as to drive the supporting plate 2 and the limiting push block 35 to move upward along the Z axis for a third preset distance as a whole, so that the bottom end surface of the limiting push block 35 is higher than the top end surface of the first workpiece.

[0081] By setting step S0 before step S1, on the one hand, it can be ensured that the limit push block 35 will not collide with the first workpiece when the limit push block 35 touches the welding head 20, so as to better protect the first workpiece; on the other hand, the bottom end surface of the limit push block 35 is higher than the top end surface of the first workpiece, so as to facilitate the limit push block 35 to move downward along the Z axis to touch the top end surface of the first workpiece in step S3.

[0082] Furthermore, since the lifting and lowering adjustment function on the Z-axis is realized by the second driving member 41 and the second adjusting member 44 in this embodiment, after the first workpiece and the second workpiece 10 are welded, and when the first workpiece is larger in volume or is an irregular structure or the welding area between the first workpiece and the second workpiece 10 is smaller, at this time, since the first workpiece is not convenient to be directly taken out from the two limit push blocks 35, the second driving member 41 is operated to drive the second adjusting member 44 to move, so as to drive the supporting plate 2, the limit push block 35 and the second workpiece 10 to move upward along the Z-axis as a whole, so that the first workpiece and the second workpiece 10 are in an inclined state, so as to provide space for taking out the first workpiece and the second workpiece 10, and then it is beneficial to take out the first workpiece and the second workpiece 10 directly from above the first adjustment component 3, so that the taking out of the first workpiece and the second workpiece 10 is relatively simple and convenient.

[0083] The specific positioning and adjustment process of the welding positioning method in this embodiment is as follows:

[0084] First, the second driving member 41 is activated, and the second driving member 41 drives the lower wedge block 442 to move along the Y-axis, so as to drive the upper wedge block 441 and the supporting plate 2 to move upward along the Z-axis, so that the limiting push block 35 on the supporting plate 2 moves upward along the Z-axis by a third preset distance, so that the bottom end surface of the limiting push block 35 is higher than the top end surface of the first workpiece.

[0085] Afterwards, the first driving member 31 is operated so that the first output end 311 drives the first adjusting member 32 to slide along the X-axis in the sliding groove 331 of the positioning main block 33. Due to the sliding connection between the inclined surface of the first adjusting member 32 and the positioning block 34, the positioning block 34 moves on the Y-axis along the inclination direction of the inclined surface of the first adjusting member 32, thereby driving the limit push block 35 to move on the Y-axis, so that the two limit push blocks 35 approach each other until the two limit push blocks 35 touch the welding head 20 respectively. For this reason, at this time, the first driving member 31 stops working.

[0086] Then, the first driving member 31 is operated so that the first output end 311 drives the first adjusting member 32 to slide back along the X-axis in the sliding groove 331 of the positioning main block 33, so that the positioning block 34 moves on the Y-axis along the inclination direction of the inclined surface of the first adjusting member 32, thereby driving the limiting push block 35 to move on the Y-axis, so that the limiting push block 35 moves on the Y-axis away from the welding head 20 until a first preset distance. At this time, the first driving member 31 stops working, so that the distance between the outer side surface of the welding head 20 and the front side surface of the limiting push block 35 is the first preset distance; and, the clamp 361 is started to clamp the clamp rod 362 through the clamp 361 to position the clamp rod 362 and the first adjusting member 32 to ensure that the first adjusting member 32 will not move again.

[0087] Then, the second driving member 41 is operated so that the second output end drives the lower wedge block 442 to move along the Y-axis. Since the inclined surfaces of the upper wedge block 441 and the lower wedge block 442 are slidably connected, the upper wedge block 441 and the supporting plate 2 are driven to move downward along the Z-axis, thereby causing the limiting push block 35 on the supporting plate 2 to move downward along the Z-axis until the bottom end surface of the limiting push block 35 touches the top end surface of the first workpiece and the second driving member 41 stops working.

[0088] Afterwards, the second driving member 41 is operated so that the second output end drives the lower wedge block 442 to move along the Y-axis, thereby driving the upper wedge block 441 and the supporting plate 2 to move upward along the Z-axis, so that the limiting push block 35 on the supporting plate 2 moves upward along the Z-axis away from the first workpiece by a second preset distance. At this time, the second driving member 41 stops working, so that the distance between the top end surface of the first workpiece and the bottom end surface of the limiting push block 35 is the second preset distance.

[0089] Then, the welding head 20 welds the first workpiece to one end of the second workpiece 10 to ensure the welding quality between the first workpiece and the second workpiece 10 .

[0090] Finally, when welding is completed, the second driving member 41 is operated to drive the limiting push block 35 on the supporting plate 2 and the second workpiece 10 to move upward along the Z-axis away from the first workpiece, so that the first workpiece and the second workpiece 10 are in an inclined state, so that the first workpiece and the second workpiece 10 can be directly taken out from above the first adjustment component 3, thereby completing the entire distance adjustment and welding process.
