Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and in particular to a plate welding device for steel structures. Background Art

[0002] Purlin support plates are connecting plates that connect purlins and steel frame beams. They are made of two steel plates welded together. Since steel structure roofs with purlins are generally sloped roofs, the roof beams used to support the purlins have a slope. The purlins placed on the roof beams are unstable, so purlin support plates are needed to enhance the overall stability.

[0003] At present, purlin support plates are usually welded using semi-automated equipment. First, the worker places the steel plate with through holes flat on the workbench, and then places another steel plate vertically in the middle of the flat steel plate. The two steel plates form a T shape. Then, a driving mechanism such as an electric slide is used to drive the welding gun to move horizontally, so that the welding gun can move along the butt joint of the two steel plates for welding. After welding is completed, the worker removes it.

[0004] Among the currently available related technical solutions, Chinese patent CN218874215U discloses an automatic welding machine for purlin support plates, and Chinese patent CN114178747A discloses an automatic welding machine for steel structure purlin support plates. The operation methods of both are similar to the description above, and both require manual placement of two steel plates, resulting in low production efficiency. In addition, the placement process is affected by subjective factors such as work attitude and work experience, and defective products may be produced due to inaccurate placement. Summary of the Invention

[0005] In order to overcome the disadvantage of the prior art that steel plates need to be placed manually, the present invention provides a plate welding device for steel structures that can reduce manual operations.

A material pushing plate for pushing the vertical plate into the stop frame is fixedly connected to the lifting frame.

[0009] As a further preferred solution, it further includes a magnet and a magnetic rod. A magnet is fixedly connected inside the vertical clamping plate, enabling the vertical clamping plate to fix the vertical plate without too much clamping force. A magnetic rod is fixedly connected to the first material frame. The magnetic rod is used to limit the movement of the lower vertical plate.

[0010] The lower guide rod is provided with a No. 2 spring, and the side touch rod is connected with a limiting assembly, and the limiting assembly is used to drive the contact frame and the side touch rod to move synchronously to keep the cross plate clamped.

[0011] As a further preferred solution, the limit assembly includes a limit rod, a No. 3 spring and a separation rod. A limit hole is provided on the resistance frame. The side touch rod is slidably connected to the limit rod. The No. 3 spring is sleeved on the limit rod. The limit rod can enter the limit hole to connect the side touch rod and the resistance frame together. A separation rod is fixed under the welding seat. The separation rod is squeezed together with the limit rod to drive it to move out of the limit hole.

[0013] As a further preferred solution, it also includes a range-reducing mechanism that can enable the horizontal splint to continue moving when the vertical splint is stationary. The range-reducing mechanism is connected to the lifting frame. The range-reducing mechanism includes a range-reducing guide rod, a No. 4 spring, an upper baffle and a lower baffle.

[0014] As a further preferred solution, it also includes a positioning rod and a positioning ring for limiting the movement of the pushing plate. The positioning rod is fixedly connected to the bearing seat, and the positioning ring is rotatably connected to the pushing plate. The positioning ring can be sleeved on the positioning rod.

[0015] As a further preferred solution, a welding frame is further included. The supporting seat is fixedly connected to the welding frame, and the automatic welding gun is fixedly installed on the welding frame.

[0016] The present invention has the following advantages:

[0017] 1. This device can realize the synchronous loading and docking of two steel plates, and after the docking is completed, it can drive the steel plates to move to realize welding. It can also push out the last welded purlin support plate for unloading, solving the defect of the current welding equipment that requires workers to manually place the steel plates. It not only improves production efficiency and reduces manpower consumption, but also helps to ensure the stability of product quality.

[0018] 2. The push plate can automatically push the steel plate in the No. 1 material frame to the top of the stop frame, so that the push plate can push a single steel plate into the stop frame during its downward movement, so that the vertical clamping plate can clamp and load the steel plate individually;

[0019] 3. By setting a magnetic rod on the No. 1 material frame, it can not only prevent the steel plate from moving upward, so that the vertical clamping plate can clamp the steel plate in the stop frame individually, but also prevent the steel plate in the No. 1 material frame from automatically falling into the stop frame, causing the limit rod to be unable to reset;

[0020] 4. By arranging magnets on the vertical clamping plates, the vertical clamping plates can still clamp the steel plates without too much clamping force. This not only facilitates the vertical clamping plates to move to both sides of the steel plates for clamping, but also enables the steel plates to move normally for welding when the vertical clamping plates are not loosened.

[0021] 5. The contact frame squeezes the side contact rod to enable the horizontal guide plate to drive the horizontal clamping plate to clamp the lowest steel plate of the No. 2 material frame. Since the distance between the No. 2 material frame and the welding plate can only accommodate one steel plate, the horizontal clamping plate can drive the single steel plate to push and load the material.

[0022] 6. After the limit rod enters the limit hole, the contact frame and the side contact rod are connected, so that the transverse splint can maintain the clamping of the steel plate during the movement, and the separation rod can drive the limit rod to disengage from the limit hole by squeezing it, so that the transverse splint can automatically release the clamping when it moves to the set position.

DETAILED DESCRIPTION

[0033] The following further illustrates the technical solution with reference to specific embodiments. It should be noted that terms such as "up," "down," "left," and "right" used herein to indicate directions refer only to the positions of the structures depicted in the corresponding drawings. Component numbers, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connected" and "coupled" in this application, unless otherwise specified, include both direct and indirect connections (couplings).

[0034] Example 1: A plate welding device for steel structure, such as Figures 1 - 7As shown in the figure, it includes a main frame 1, an automatic welding gun 101, a lifting frame 102, a vertical support 103, a vertical clamping plate 104, a vertical spring 1041, a bearing seat 105, a first material frame 106, a stop frame 107, a horizontal slide bar 108, a horizontal support plate 109, a horizontal clamping plate 110, a second material frame 111 and a welding seat 112. Two automatic welding guns 101 are symmetrically and fixedly arranged inside the main frame 1. The automatic welding gun 101 is a prior art. A lifting frame 102 is slidably connected to the main frame 1 in the vertical direction. A vertical support 103 is installed on the lifting frame 102. Two vertical clamping plates 104 are slidably connected to the vertical support 103 in the horizontal direction. A vertical spring 1041 is sleeved on the guide rod of the vertical clamping plate 104. When the two vertical clamping plates 104 move away from each other, the vertical spring 1041 will be compressed. A bearing seat 105 is fixedly connected to the main frame 1. The top of the bearing seat 105 is fixedly connected to a first material frame 106. The first material frame 106 is a U-shaped frame body. The first material frame 106 is used to store steel plates placed vertically. Hereinafter, the steel plates placed vertically will be simply referred to as vertical plates. Two stop frames 107 are symmetrically and fixedly connected to the bearing seat 105. The upper end of the stop frame 107 passes through the bearing seat 105 and is fixedly connected to the bottom of the first material frame 106. The stop frame 107 is a U-shaped frame body. The vertical plates in the first material frame 106 can be pushed into the two stop frames 107. Only one vertical plate can be accommodated in the two stop frames 107 together. The two stop frames 107 are symmetrically arranged and have a gap between them. The vertical clamping plate 104 can move vertically between the two stop frames 107 to clamp the vertical plate. The vertical clamping plate 104 is used to clamp the vertical plate in the stop frame 107 and convey it between the two automatic welding guns 101 below. Two slide ways are symmetrically opened inside the main frame 1. A horizontal slide bar 108 is slidably connected to each slide way in the horizontal direction. A horizontal support plate 109 is fixedly connected to the two horizontal slide bars 108 together. Four horizontal clamping plates 110 are symmetrically installed on the horizontal support plate 109. The horizontal clamping plate 110 is L-shaped. A welding seat 112 is fixedly installed on the ground inside the main frame 1. A second material frame 111 is fixedly connected to the main frame 1. The second material frame 111 is a frame structure that is transparent up and down. The second material frame 111 is used to store steel plates placed horizontally. Hereinafter, the steel plates placed horizontally will be simply referred to as horizontal plates. The second material frame 111 is located above the welding seat 112, and the distance between the second material frame 111 and the welding seat 112 can only accommodate one horizontal plate to pass through. The horizontal clamping plate 110 is used to clamp the horizontal plate that falls on the welding seat 112. The vertical clamping plate 104 will convey the vertical plate downward between the two automatic welding guns 101 and make the left end of the vertical plate between the two automatic welding guns 101. The horizontal clamping plate 110 will convey the horizontal plate downward to the vertical plate and make the left ends of the horizontal plate and the vertical plate aligned. After the automatic welding gun 101 spot-welds the horizontal plate and the vertical plate together, the horizontal clamping plate 110 will drive the two of them to translate synchronously, so that the automatic welding gun 101 can complete the welding of the entire butt joint seam.

[0035] The vertical plate refers to the steel plate that needs to be placed vertically during welding, and the horizontal plate refers to the steel plate that needs to be placed horizontally during welding. The two steel plates are arranged in a T shape. Before using this device, first stack multiple vertical plates vertically into the first material frame 106. At this time, there is no vertical plate in the stop frame 107. Then stack multiple horizontal plates into the second material frame 111. Since the horizontal clamping plate 110 is located at Figure 1In the initial position shown in the figure, the horizontal clamping plate 110 in the initial position is in a closed state, resulting in the cross plate being unable to fall on the welding seat 112; then control the lifting frame 102 to reciprocate up and down once. When the lifting frame 102 moves downward, it will drive the vertical clamping plate 104 to approach the automatic welding gun 101 below through the vertical support 103, and a vertical plate directly above the stop frame 107 will be pushed downward, that is, a vertical plate in the first material frame 106 will be pushed into the stop frame 107. During this process, the horizontal slide bar 108 will slide in the direction of the automatic welding gun 101, thereby driving the horizontal clamping plate 110 to move away from below the second material frame 111, enabling the cross plate at the bottom to fall onto the welding seat 112; when the lifting frame 102 returns upward, it will drive the vertical clamping plate 104 to move upward through the vertical support 103. During the movement of the vertical clamping plate 104, the inclined surface on it will contact the edge of the lower end of the vertical plate in the stop frame 107. The vertical plate in the stop frame 107 cannot move upward, so the vertical clamping plate 104 will move to both sides of the vertical plate under the action of the inclined surface and compress the vertical spring 1041. Then the vertical clamping plate 104 moves upward along the outer surface of the vertical plate, and the vertical clamping plate 104 will maintain contact with the surface of the vertical plate under the action of the vertical spring 1041. During this process, the horizontal clamping plate 110 will move downward and return to the position below the second material frame 111, and when it is about to move directly below the second material frame 111, the four horizontal clamping plates 110 start to contract, thereby positioning and clamping the cross plate on the welding seat 112; the first reciprocating up and down movement of the lifting frame 102 is to complete the feeding of the vertical plate and the cross plate. Then control the lifting frame 102 to move downward again. The vertical clamping plate 104 drives the vertical plate to move between the two automatic welding guns 101, and the horizontal clamping plate 110 drives the cross plate to move below the two automatic welding guns 101. When the left end face of the cross plate moves to the positions of the two automatic welding guns 101, the vertical plate just presses on the top of the cross plate, and the left end of the vertical plate is aligned with the left end of the cross plate. The two automatic welding guns 101 are directly opposite the left end of the butt joint seam of the cross plate and the vertical plate. The cross plate and the vertical plate form a T shape, and then the automatic welding gun 101 starts welding, thereby first welding and fixing the left ends of the cross plate and the vertical plate together. During the continuous movement of the horizontal clamping plate 110 driving the cross plate, since the left ends of the cross plate and the vertical plate have been welded together, the cross plate will drive the vertical plate to move synchronously in the horizontal direction, thereby welding the cross plate and the vertical plate into a T-shaped purlin support plate during the movement. When the welding is completed, the horizontal slide bar 108 is about to move to the set position. When the horizontal slide bar 108 moves to the set position, the horizontal clamping plate 110 will automatically release the clamping of the cross plate. Then control the lifting frame 102 to return upward, and the horizontal slide bar 108 slides and returns in the direction of the second material frame 111; during the process of welding the next purlin support plate, since the horizontal clamping plate 110 drives the cross plate to move along the surface of the welding seat 112, and the previously welded cross plate is on the welding seat 112, the previously welded purlin support plate can be pushed off the welding seat 112.

[0036] As Figure 2 , Figure 5 and Figure 6 shown, it further includes a baffle mechanism for preventing the vertical plate from falling out of the stop frame 107. The baffle mechanism is connected to the vertical support 103. The baffle mechanism includes a limit drop rod 2, a first spring 201, a trapezoidal block 202, and a top plate 203. The limit drop rod 2 is slidably connected to the stop frame 107 in the horizontal direction. When the limit drop rod 2 moves to the lower part of the stop frame 107, it can prevent the vertical plate from falling out. A first spring 201 is sleeved on the guide rod of the limit drop rod 2. When the two limit drop rods 2 move away from each other, the first spring 201 will be compressed. Two trapezoidal blocks 202 are symmetrically fixed on the limit drop rod 2. The top plate 203 is fixed on the vertical support 103. When the top plate 203 moves upward, it will squeeze the trapezoidal blocks 202 on both sides, causing the two limit drop rods 2 to move away from each other to move away from the lower part of the stop frame 107.

[0037] When the limit drop rod 2 is located below the stop frame 107, it will prevent the vertical plate from falling. When the vertical clamping plate 104 moves to both sides of the vertical plate and the vertical support 103 continues to move upward, the top plate 203 will squeeze the trapezoidal blocks 202 to make the two limit drop rods 2 move away from each other to move away from the lower part of the stop frame 107, and will compress the first spring 201; when the vertical clamping plate 104 moves downward, it will first drive the vertical plate in the stop frame 107 downward, and the vertical plate will prevent the limit drop rod 2 from resetting. Only when the vertical plate is separated from the limit drop rod 2 will the first spring 201 push it to reset.

[0038] As Figure 2 and Figure 5 shown, it further includes a pushing mechanism for pushing the vertical plate into the stop frame 107. The pushing mechanism is connected to the first material frame 106. The pushing mechanism includes a pushing frame 204, a pushing plate 205, a first pulling spring 206, and a material pushing plate 207. The pushing frame 204 is fixed on the first material frame 106. The pushing plate 205 is slidably connected to the pushing frame 204 in the horizontal direction, and the pushing plate 205 slides in the first material frame 106. The pushing plate 205 is used to push the vertical plate in the first material frame 106. The first pulling spring 206 is sleeved on the pushing frame 204. One end of the first pulling spring 206 is fixed to the pushing plate 205, and the other end of the first pulling spring 206 is fixed to the pushing frame 204. The first pulling spring 206 is used to drive the pushing plate 205 to move in the direction close to the stop frame 107. The material pushing plate 207 for pushing the vertical plate into the stop frame 107 is fixed on the lifting frame 102.

[0039] When it is necessary to place a vertical plate into the No. 1 material frame 106, first push the pushing plate 205 in the direction away from the pushing frame 204, and then place the vertical plate between the pushing plate 205 and the No. 1 material frame 106. The first tension spring 206 will always apply tension to the pushing plate 205, thereby automatically pushing the vertical plate toward the top of the stop frame 107. When the lifting frame 102 moves downward, it will drive the pushing plate 207 to push the vertical plate directly below into the stop frame 107.

[0040] like Figure 4 and Figure 5 As shown, it also includes a magnet 3 and a magnetic rod 301. The magnet 3 is fixedly connected to the vertical clamp 104, so that the vertical clamp 104 can fix the vertical plate without too much clamping force. The vertical clamp 104 is provided with an inclined surface. During the upward movement of the vertical clamp 104, it will move to the side of the vertical plate through the force of the inclined surface, so that the vertical plate is adsorbed on the magnet 3. A magnetic rod 301 is fixedly connected to the No. 1 material frame 106. The magnetic rod 301 is magnetic. The magnetic rod 301 is used to prevent the vertical plate from moving upward so that the vertical clamp 104 can move to the side of the vertical plate, and the magnetic rod 301 can attract the vertical plate to prevent it from falling downward, so that the vertical plate can only move into the stop frame 107 under the push of the push plate 207.

[0041] By arranging magnets 3 on the vertical clamping plate 104, the vertical clamping plate 104 can still fix the vertical plate when the vertical spring 1041 does not have a large elastic force, thereby preventing the vertical clamping plate 104 from being difficult to move to the sides of the vertical plate when the vertical spring 1041 has a large elastic force, and facilitating the horizontal plate to drive the vertical plate to move horizontally together; when the vertical clamping plate 104 transports the vertical plate in the stop frame 107 downward, the magnetic rod 301 can prevent the vertical plate below from moving downward through magnetic force, thereby preventing the vertical plate from following the downward movement and affecting the reset of the drop limit rod 2, so that the vertical plate can enter the stop frame 107 only under the push of the push plate 207. During the upward movement of the vertical clamping plate 104, the magnetic rod 301 can prevent the vertical plate from moving upward, so that the vertical clamping plate 104 can move to the side of the vertical plate by using its own inclined surface and the squeezing of the vertical plate.

[0042] Example 2: Based on Example 1, Figure 3 、 Figure 7 、 Figure 8 and Figure 9As shown, it also includes a transmission mechanism for driving the transverse splint 110, the transmission mechanism is connected to the transverse support plate 109, the transmission mechanism includes a transverse guide plate 4, a second tension spring 401, a connecting rod 402, a side touch rod 403, a lower guide rod 404, a contact frame 405, a second spring 406 and a limit assembly, the transverse support plate 109 is symmetrically slidingly connected with two transverse guide plates 4, the guide rod of the transverse guide plate 4 is sleeved with a second tension spring 401, one end of the second tension spring 401 is fixed to the transverse guide plate 4, and the other end of the second tension spring 401 is fixed to the transverse support plate 109, each transverse guide plate 4 is symmetrically slidingly connected with two connecting rods 402, the transverse splint 110 is fixed to the top of the connecting rod 402, and the transverse support plate 109 is provided with four slides, and the four slides are in two symmetrical figure eights. shaped arrangement, each connecting rod 402 is slidably connected to an adjacent slide, and when the two transverse guide plates 4 move relative to each other, the four connecting rods 402 will shrink toward the center along the slide to drive the transverse clamping plate 110 to clamp the transverse plate on the welding seat 112, and a side touch rod 403 is fixed to the transverse guide plate 4, and the side touch rod 403 is located on the adjacent side of the two transverse guide plates 4. Two lower guide rods 404 are symmetrically fixed to the welding seat 112, and the two lower guide rods 404 are slidably connected with a contact frame 405. The contact frame 405 squeezes the side touch rod 403 to make the two transverse guide plates 4 move relative to each other, and a No. 2 spring 406 is sleeved on the lower guide rod 404. A limiting assembly is connected to the side touch rod 403, and the limiting assembly is used to drive the contact frame 405 and the side touch rod 403 to move synchronously to keep the transverse plate clamped.

[0043] In the horizontal direction of the slide bar 108 Figure 1 During the movement from the initial position shown in the figure, the contact frame 405 will squeeze the side contact rod 403 to make the two transverse guide plates 4 move relative to each other, and will stretch the second tension spring 401. The transverse guide plate 4 will drive the connecting rod 402 to slide along the slide on the transverse support plate 109, thereby driving the transverse clamping plate 110 to position and clamp the transverse plate on the welding seat 112. During the movement of the transverse slide bar 108 toward the automatic welding gun 101, the side contact rod 403 will drive the contact frame 405 to move synchronously through the limit assembly, and the contact frame 405 will pull the second spring 406 Compression, after welding is completed, the horizontal slide bar 108 will continue to slide an end distance, during this process the limit assembly will automatically release the connection with the contact frame 405, the contact frame 405 will be reset to the bottom of the No. 2 material frame 111 under the action of the No. 2 spring 406, and when the contact frame 405 is disengaged from the side contact rod 403, the horizontal guide plate 4 will move in opposite directions under the action of the second tension spring 401, thereby driving the horizontal clamping plate 110 to loosen the clamping of the horizontal plate through the connecting rod 402, and then the horizontal slide bar 108 will slide and reset toward the direction of the No. 2 material frame 111.

[0044] like Figure 3 、 Figure 8 and Figure 9As shown, the limit assembly includes a limit rod 501, a No. 3 spring 502 and a separation rod 503. A limit hole 5 is opened on the contact frame 405. The side contact rod 403 is horizontally slidably connected to the limit rod 501. The No. 3 spring 502 is sleeved on the limit rod 501. When the limit rod 501 contracts into the side contact rod 403, the No. 3 spring 502 is compressed. The limit rod 501 can enter the limit hole 5 to connect the side contact rod 403 and the contact frame 405 together. A separation rod 503 is fixed under the welding seat 112. The separation rod 503 is squeezed and matched with the limit rod 501 to drive it to move out of the limit hole 5.

[0045] In the horizontal direction of the slide bar 108 Figure 1 During the movement from the initial position shown in the figure, the limit rod 501 will be squeezed by the contact frame 405, causing it to shrink into the side contact rod 403, and the No. 3 spring 502 will be compressed. When the side contact rod 403 drives the limit rod 501 to move to face the limit hole 5, the limit rod 501 will enter the limit hole 5 under the push of the No. 3 spring 502, so that the side contact rod 403 can drive the contact frame 405 to move synchronously; when the welding is completed and the horizontal slide bar 108 continues to slide, the separation rod 503 will contact the lower sides of the two limit rods 501, and the two limit rods 501 will move away from each other through the squeezing between the inclined surfaces, thereby causing the limit rod 501 to move out of the limit hole 5, and the contact frame 405 can be reset under the action of the No. 2 spring 406.

[0046] Example 3: Based on Example 2, Figures 1 - 3 As shown, it also includes a driving mechanism for driving the lifting frame 102 and the horizontal slide bar 108 to move, and the driving mechanism includes an electric push rod 6, an articulated shaft 601 and an articulated rod 602. The electric push rod 6 is fixed to the main frame 1, and the telescopic shaft of the electric push rod 6 is fixed to the lifting frame 102. Two articulated shafts 601 are symmetrically fixed to the lower side of the lifting frame 102. One end of the articulated rod 602 is rotatably connected to the articulated shaft 601, and the other end of the articulated rod 602 is rotatably connected to the horizontal slide bar 108.

[0047] When the electric push rod 6 is extended or retracted, it can drive the lifting frame 102 to move up and down. When the lifting frame 102 moves up and down, it can drive the transverse slide bar 108 to slide along the slideway provided on the main frame 1 through the hinge shaft 601 and the hinge rod 602.

[0048] like Figure 3As shown, it also includes a range-reducing mechanism that can enable the horizontal splint 110 to continue moving when the vertical splint 104 is stationary. The range-reducing mechanism is connected to the lifting frame 102. The range-reducing mechanism includes a range-reducing guide rod 7, a No. 4 spring 701, an upper baffle 702 and a lower baffle 703. The lifting frame 102 is slidably connected to the range-reducing guide rod 7 in the vertical direction. The No. 4 spring 701 is sleeved on the range-reducing guide rod 7. The lower end of the range-reducing guide rod 7 is fixed to the vertical bracket 103. When the range-reducing guide rod 7 slides upward, the No. 4 spring 701 will be compressed. The upper baffle 702 is fixed to the vertical bracket 103, and two lower baffles 703 are symmetrically fixed to the bearing seat 105.

[0049] When the left end of the horizontal plate moves to the position of the two automatic welding guns 101, and the vertical plate is pressed on the top of the horizontal plate and the left ends of the two are aligned, the upper baffle 702 contacts the lower baffle 703, causing the vertical bracket 103 to no longer move downward, that is, the height of the vertical clamping plate 104 remains unchanged, and then the electric push rod 6 continues to extend and drives the lifting frame 102 to move downward. At this time, the No. 4 spring 701 will be compressed, and the lifting frame 102 will drive the horizontal slide bar 108 to continue to slide through the hinge rod 602, so that after the automatic welding gun 101 welds the left ends of the horizontal plate and the vertical plate together, the horizontal plate can drive the vertical plate to move horizontally to complete the welding of the entire butt joint.

[0050] like Figure 5 As shown, it also includes a positioning rod 8 and a positioning ring 801 for limiting the movement of the push plate 205. The positioning rod 8 is fixed to the support seat 105, and the positioning ring 801 is rotatably connected to the push plate 205. The positioning ring 801 can be sleeved on the positioning rod 8 to limit the sliding of the push plate 205.

[0051] Positioning rod 8 and positioning ring 801, when it is necessary to place the vertical plate into the No. 1 material frame 106, the worker can put the positioning ring 801 on the positioning rod 8 to prevent the pushing plate 205 from moving under the action of the first tension spring 206.

[0052] like Figure 5 As shown, a welding frame 9 is also included. Two welding frames 9 are symmetrically fixed to the lower side of the supporting seat 105, and the automatic welding gun 101 is fixedly installed on the welding frame 9.

[0053] The welding frame 9 serves to fix the automatic welding gun 101 , and technicians may also use other methods to fix it.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
