Description

[0002] At present, when using natural foundation to build buildings, pile drivers are usually used to press pipe piles into the ground to become foundation piles, so that the upper part of the foundation piles can bear the building. In the process of producing pipe piles, the method of welding the skirt plate and the end plate together by the welding device is: first, the skirt plate and the end plate on the chassis are pressed down by the upper pressure plate, and then the pressure rod on the outer side of the upper pressure plate is used to apply pressure to press the skirt plate and the end plate, and then the upper pressure plate is raised and reset to make the chassis rotate, and the welding gun device on the outer side of the upper pressure plate is extended into the inner side of the end plate and the skirt plate to make a 360-degree circular welding along the inner side joint of the end plate and the skirt plate. In this welding method, the upper pressure plate needs to give way to the welding gun device and the skirt plate and the end plate are pressed by the pressure rod. When the chassis rotates, the pressure rod will squeeze out the skirt plate, resulting in the skirt plate and the end plate not fitting together, which will cause the welding workpiece to be scrapped and the equipment to be unstable.

[0041] Embodiment 1:

[0042] See also Figure 1The present embodiment provides a skirt plate assembly welding device 10, comprising a skirt plate assembly welding device body, a frame 20, a material discharge device 60 and two material feed devices. Figure 1 In the coordinate system shown in , the length direction of the frame 20 is defined as the X-axis direction, the width direction of the frame 20 is defined as the Y-axis direction, and the vertical (plumb) direction is defined as the Z-axis direction, wherein the horizontal direction includes the X-axis direction and the Y-axis direction, and the X-axis, Y-axis, and Z-axis directions are perpendicular to each other. The frame 20 is used to install the skirt plate assembly welding device body, the unloading device 60, and the two loading devices. The two loading devices are respectively used to transport the skirt plate 80 and the end plate 70 to the skirt plate assembly welding device body. The skirt plate assembly welding device body presses and welds the skirt plate 80 and the end plate 70 together to form a welding workpiece, and the unloading device 60 delivers the welding workpiece. That is, while improving the degree of automation of loading and unloading, the welding machine can also effectively fit the skirt plate 80 and the end plate 70 for welding, thereby improving the quality of the welding workpiece and the stability of the equipment.

[0043] Among them, see Figure 1 , 6 7. The skirt plate assembly welding device body includes a mounting platform 100, a chassis 101, a pressure plate 102, a pressure plate connecting plate 103, a pressure plate driving mechanism 104 and a welding mechanism 105. The chassis 101 can rotate on the mounting platform 100. The two feeding devices are used to transport the skirt plate 80 and the end plate 70 to the chassis 101 respectively; the pressure plate 102 and the pressure plate connecting plate 103 are fixed in the axial direction and can rotate relative to the pressure plate connecting plate 103. The pressure plate driving mechanism 104 and the pressure plate connecting plate 103 is connected to drive the pressure plate 102 to move up and down on the chassis 101 so that the pressure plate 102 can press the skirt 80 and the end plate 70 on the chassis 101; in some embodiments, the portion of the pressure plate 102 that contacts the top of the skirt 80 is set as a plane, so that the pressure plate 102 and the top of the skirt 80 form an annular line contact. Compared with the point contact between the pressure rod and the skirt and the end plate in the prior art, the line contact between the pressure plate 102 and the skirt 80 can more stably press the skirt 80. Further, a circle of annular protruding buckling parts 123 protruding toward the chassis 101 is provided on the plane where the pressure plate 102 contacts the top of the skirt 80, and the top of the skirt can be set outside the buckling part 123, so that the pressure plate 102 can better limit and press the skirt 80.

[0044] See also Figure 6 , 7The welding mechanism 105 is installed on the pressure plate connecting plate 103. The pressure plate 102 and the pressure plate connecting plate 103 are respectively provided with welding ports 108. The welding mechanism 105 penetrates the welding ports 108 to weld the inner joint of the end plate 70 and the skirt plate 80 so as to weld the skirt plate 80 and the end plate 70 together. Even if the welding mechanism 105 is welded on the inner side of the pressure plate 102, there is no need to avoid the pressure plate 102, which can facilitate the welding of the welding mechanism 105, and keep the skirt plate 80 and the end plate 70 always in contact during the welding process. Compared with the prior art, the pressure plate needs to give way to the welding gun device and the skirt plate 80 and the end plate 70 are pressed by the pressure rod. When the chassis 101 rotates, the pressure rod will squeeze out the skirt plate, resulting in the problem that the skirt plate and the end plate do not fit together. In this embodiment, the pressure plate 102 and the pressure plate connecting plate 103 are provided with welding ports 108 for the welding mechanism 105 to pass through the pressure plate 102 and the pressure plate connecting plate 103 to weld the skirt plate 80 and the end plate 70, so that the pressure plate 102 does not need to give way to the welding mechanism 105, so that the skirt plate 80 can always be pressed against the end plate 70 during the welding process, so that the skirt plate and the end plate can always keep in contact during the welding process, which is conducive to improving the quality of the welding workpiece and the stability of the equipment. As the chassis 101 rotates, the skirt plate 80 and the end plate 70 rotate synchronously and can drive the pressure plate 102 to rotate on the pressure plate connecting plate 103, and the welding mechanism 105 can effectively weld the skirt plate 80 and the end plate 70 together. The pressure plate driving mechanism 104 of this embodiment applies a pressing force to the pressure plate 102 through the pressure plate connecting plate 103 , and the pressure plate 102 fits with the inner wall of the inner joint through the snap-fitting portion 123 , which can further increase the pressing force.

[0045] In other embodiments, the welding mechanism 105 may be installed on the frame 20 at a position where it can pass through the welding opening 108 for welding.

[0046] In this embodiment, two pressure plate driving mechanisms 104 are provided. Figure 1 , the two pressure plate driving mechanisms 104 are respectively connected to the front and rear sides of the pressure plate connecting plate 103, so that the pressure plate connecting plate 103 can drive the pressure plate 102 to rise and fall smoothly. The number of the pressure plate driving mechanisms 104 can also be specifically set according to actual production needs. In another embodiment, the two pressure plate driving mechanisms 104 are respectively connected to the left and right sides of the pressure plate connecting plate 103. Specifically, the pressure plate driving mechanism 104 is preferably a cylinder, and of course it can also be a driving component such as an oil cylinder.

[0047] Specifically, the welding device further includes a chassis 101 driving mechanism, which is used to drive the chassis 101 to rotate on the mounting platform 100. More specifically, the chassis 101 driving mechanism is installed below the mounting platform 100, and the chassis 101 is connected to the chassis 101 driving mechanism via a rotating shaft, and the chassis 101 driving mechanism drives the chassis 101 to rotate. Figure 6 , 7 The worm gear 106 and the rotating motor 107 may also be other driving components such as a servo motor or a pulley. Thus, the chassis 101 is effectively rotated on the mounting platform 100, so that the skirt plate 80 and the end plate 70 can be effectively welded together.

[0048] For specific implementation, please refer to Figure 5 A plurality of leak holes are provided on the chassis 101, which can reduce the weight of the chassis 101 and provide more margin for elastic deformation.

[0049] In this example, see Figure 6 , 7 A slewing bearing 117 is installed on the side of the pressure plate connecting plate 103 close to the chassis 101. The slewing bearing 117 has a through hole connected to the welding port 108. The pressure plate 102 is installed on the side of the slewing bearing 117 close to the chassis 101, thereby achieving effective rotation of the pressure plate 102 on the pressure plate connecting plate 103.

[0050] Specifically, see Figure 6 , 7 The welding mechanism 105 is installed on the pressure plate connecting plate 103, that is, the welding mechanism 105 can be raised and lowered synchronously with the pressure plate connecting plate 103, and the welding mechanism 105 does not need to be significantly raised and lowered through other driving components, so that the welding mechanism 105 can effectively weld the skirt plate 80 and the end plate 70.

[0051] Preferably, see Figure 6 , 7 The number of welding mechanisms 105 is set to two, and the welding port 108 is formed at the center of the pressure plate 102 and the pressure plate connecting plate 103. Even if the welding mechanisms 105 are arranged circumferentially around the welding port 108, the distances between the welding mechanisms 105 and the inner joints of the end plate 70 and the skirt plate 80 are the same, which facilitates welding the inner joints of the end plate 70 and the skirt plate 80. Of course, the number of welding mechanisms 105 can also be specifically set according to actual production needs.

[0052] Specifically, see Figure 1 , 6 7. The welding device also includes a guide rod 109, which is vertically mounted on the mounting platform 100. The pressure plate connecting plate 103 can move up and down along the guide rod 109 so that the pressure plate 102 can move toward or away from the chassis 101 (Z-axis direction), thereby providing a guide for the lifting and lowering of the pressure plate 102.

[0053] In this example, see Figure 1 , 4The number of guide rods 109 is set to four. The welding device also includes a top plate 110. The two ends of the guide rods 109 are respectively connected to the top plate 110 and the mounting platform 100 and arranged corresponding to the four corners of the top plate 110 and the mounting platform 100. This arrangement can help improve the stability of the structure and facilitate the smooth lifting and lowering of the pressure plate connecting plate 103, that is, the smooth lifting and lowering of the pressure plate 102. Of course, the number of guide rods 109 can also be specifically set according to actual production needs. For specific implementation, please refer to Figure 5-8 The welding mechanism 105 includes a welding gun, one end of which is connected to a welding gun wire connected to a power source, and an idler wheel assembly 115 for winding the welding gun wire is provided on the top plate 110 to prevent the welding gun wire on the welding gun from rubbing against the frame 20 when the pressure plate connecting plate 103 is lifted and lowered. In this embodiment, the number of the idler wheel assemblies 115 matches the number of the welding mechanisms 105.

[0054] In this embodiment, the welding device further includes a horizontal position adjustment mechanism 111, see Figure 8 The platen connecting plate 103 is provided with a guide rail 112 extending along the length direction (X-axis direction) of the platen connecting plate 103. The welding mechanism 105 slides left and right on the guide rail 112 through a slider. The horizontal position adjustment mechanism 111 is used to drive the welding mechanism 105 to slide on the guide rail 112 to adjust the left and right position of the welding mechanism 105. In this way, the left and right position of the welding mechanism 105 can be effectively adjusted, so that the welding mechanism 105 can weld various end plates 70 and skirt plates 80.

[0055] In another embodiment, the guide rail 112 extends along the width direction (Y-axis direction) of the pressure plate connecting plate 103, so that the front and rear positions of the welding mechanism 105 can be effectively adjusted.

[0056] A more preferred embodiment is that the welding device further comprises a mounting seat 113 and an up and down position adjustment mechanism 114, see Figure 6-8 The horizontal position adjustment mechanism 111 is connected to the welding mechanism 105 through the mounting seat 113, and the vertical position adjustment mechanism 114 is used to drive the welding mechanism 105 to move up and down on the mounting seat 113 to adjust the vertical position of the welding mechanism 105. In this way, the vertical position of the welding mechanism 105 can be effectively adjusted, further improving the adaptability of the welding device.

[0057] In order to further improve the welding efficiency, the welding device further includes a welding lifting plate 118, a support plate 119 and a limit adjustment member 120, see Figure 6-8The mounting seat 113 is provided with a lifting movable groove 121 arranged along its height direction (Z-axis direction), and a lifting slider is provided on the welding lifting plate 118. The up and down position adjustment mechanism 114 is used to drive the welding lifting plate 118 to drive the welding mechanism 105 to move up and down on the mounting seat 113. As the welding lifting plate 118 is raised and lowered on the mounting seat 113, the lifting slider can slide up and down on the lifting movable groove 121, and the support plate 119 can be rotated on the welding lifting plate 118 to adjust the welding mechanism 105 to the desired inclination. The limit adjustment member 120 is used to lock the support plate 119 on the welding lifting plate 118 to maintain the inclination of the support plate 119. Specifically, the support plate 119 is provided with an adjustment through hole 122, the welding lifting plate 118 is provided with a connection hole, and the limit adjustment member 120 is provided with the adjustment through hole 122 and the connection hole. After the support plate 119 is rotated on the welding lifting plate 118 to adjust the welding mechanism 105 on the support plate 119 to the desired inclination, the limit adjustment member 120 is threadedly connected with the above-mentioned hole to lock the support plate 119. The limit adjustment member 120 is preferably a screw. More specifically, the adjustment through hole 122 is provided with an arc shape, thereby limiting the rotation angle of the support plate 119 on the welding lifting plate 118.

[0058] In this embodiment, the mounting seat 113 is slidably connected to the guide rail 112 via a sliding member. Figure 6-8 The mounting seat 113 can also be rotated on the sliding member and then adjusted to a desired placement angle, further improving the position adjustment efficiency of the welding mechanism 105. Figure 8 The connection structure between the mounting seat 113 and the sliding member is roughly the same as the connection structure between the support plate 119 and the welding lifting plate 118. Corresponding limit adjustment members 120 and adjustment through holes 122 may also be provided to effectively adjust the placement angle of the mounting seat 113, which will not be repeated here.

[0059] In addition, the outer cover of the horizontal position adjustment mechanism 111 is provided with a protective cover 116, see Figure 6-8 A movable opening is provided on the protective cover 116 to facilitate the welding mechanism 105 to slide left and right on the horizontal position adjustment mechanism 111 through the mounting seat 113.

[0060] See also Figure 6-8 In a specific implementation, the horizontal position adjustment mechanism 111 and the up-and-down position adjustment mechanism 114 are preferably cylinders, but they can also be driving components such as oil cylinders and motors.

[0061] Specifically, see Figure 1 The mounting platform 100 is mounted on the frame 20 , and the two loading devices are an end plate loading device 30 and a skirt plate loading device 40 , respectively. The end plate loading device 30 and the skirt plate loading device 40 are located at the left and right sides of the mounting platform 100 .

[0062] Both feeding devices include a feeding drive mechanism and two symmetrically arranged grippers, the two grippers cooperate to form a gripping opening for gripping the skirt board or the end board, and the feeding drive mechanism is used to drive the two grippers to move in a horizontal direction to adjust the size of the gripping opening to grip the skirt board 80 or the end board 70. The feeding drive mechanism is respectively implemented as an end board feeding drive mechanism 300 and a skirt board feeding drive mechanism 400, and the grippers are respectively implemented as an end board gripper 301 and a skirt board gripper 401.

[0063] Among them, see Figure 2 The end plate feeding device 30 includes an end plate clamp and an end plate feeding drive mechanism 300. The end plate clamp is used to clamp the end plate 70 and can move to the right or left direction (X-axis direction) on the frame 20. The end plate feeding drive mechanism 300 is used to drive the end plate clamp to move to the right or left direction (X-axis direction) on the frame 20 to approach or move away from the chassis 101; please refer to Figure 3 The skirt board loading device 40 includes a skirt board clamp and a skirt board loading drive mechanism 400. The skirt board clamp is used to clamp the skirt board 80 and can move to the left or right direction (X-axis direction) on the frame 20. The skirt board loading drive mechanism 400 is used to drive the skirt board clamp to move to the left or right direction (X-axis direction) on the frame 20 to approach or move away from the chassis 101. In this way, the skirt board 80 and the end plate 70 are clamped by the above-mentioned clamp, and the above-mentioned loading drive mechanism drives the clamp to be transported to the chassis 101 direction (Z-axis direction) on the left and right sides of the frame 20, so that the skirt board 80 and the end plate 70 can be effectively transported to the chassis 101 for compression and welding, which is convenient for loading to improve welding efficiency.

[0064] In this example, see Figure 2 The end plate clamp includes two symmetrically arranged end plate grippers 301 and an end plate clamping mechanism. The two end plate grippers 301 can move relatively on the frame 20 and cooperate to form an end plate clamping opening 302 for clamping the end plate 70. The end plate clamping mechanism is used to drive the two end plate grippers 301 to move relatively and adjust the size of the end plate clamping opening 302 to clamp the end plate 70. In this way, the end plate 70 can be effectively clamped, so that the end plate 70 can be effectively transported.

[0065] Specifically, see Figure 2 Each end plate clamping hand 301 includes an end plate clamping plate and two end plate clamping parts 305. The end plate clamping plate is an integrated structure, on which there are an end plate base plate 303 and an end plate clamping part 304. The two end plate clamping parts 305 are screwed on the lower end of the end plate clamping part 304 through threaded cooperation. When the distance between the two end plate clamping hands 301 becomes larger, the end plate clamping parts 305 can clamp the side wall of the inner circular hole of the end plate 70. The above-mentioned end plate clamping parts 305 are roughly columnar structures. Such a structure can facilitate the disassembly and assembly of the end plate clamping parts 305 and facilitate replacement.

[0066] For specific implementation, please refer to Figure 2 The end plate clamping mechanism includes two end plate clamping cylinders, which are respectively connected to the two end plate clamps 301. The two end plate clamping cylinders respectively drive the two end plate clamps 301 to move in the direction away from or close to each other (X-axis direction), thereby realizing the opening or closing function of the two end plate clamps 301.

[0067] Horizontal guide devices 50 are provided on both the front and rear sides of the frame 20 along the length direction (X-axis direction), see Figure 2 The end plate feeding drive mechanism 300 includes an end plate screw 306 and an end plate screw motor 307, wherein the end plate clamping mechanism slides on the horizontal guide device 50 through the end plate slide 308 and is connected to the two end plate clamps 301, the output shaft of the end plate screw motor 307 is connected to the end plate screw 306, and drives the end plate screw 306 to rotate; the end plate screw 306 is connected to the end plate slide 308, so when the end plate screw 306 rotates, it can drive the end plate slide 308 to move along the length direction (X-axis direction) of the frame 20. Specifically, both sides of the end plate slide 308 Two end plate clamping cylinders (not shown in the figure) are respectively provided, and are connected to the two end plate clamping hands 301 through the two end plate clamping cylinders, thereby, the end plate slide 308, the end plate clamping cylinder and the end plate clamping hands 301 form a movable whole, which can be driven by the end plate screw rod 306 to move as a whole on the horizontal guide device 50 along the length direction (X-axis direction) of the frame 20, and the end plate clamping mechanism on the end plate slide 308 drives the two end plate clamps 301 to move relative to each other, and the end plate clamp realizes the clamping and loosening of the end plate 70 by changing the relative distance between the two end plate clamps 301.

[0068] In this example, see Figure 3 The skirt board clamp includes two symmetrically arranged skirt board grippers 401 and a skirt board clamping mechanism. The two skirt board grippers 401 can move relative to each other on the frame 20 and cooperate to form a skirt board clamping opening 402 for clamping the skirt board 80. The skirt board clamping mechanism is used to drive the two skirt board grippers 401 to move relative to each other and adjust the size of the skirt board clamping opening 402 to clamp the skirt board 80. In this way, the skirt board 80 can be effectively clamped, so that the skirt board 80 can be effectively transported.

[0069] More specifically, see Figure 3 , 910. Each skirt board clamp 401 includes a skirt board base plate 403, a skirt board clamping member 404 and two skirt board clamping members 405. The two skirt board clamping members 405 are screwed to the lower end of the skirt board clamping member 404 by threaded engagement. The skirt board clamping member 404 can move in the left and right directions (X-axis direction) of the skirt board clamping member 404 and maintain the skirt board clamping member 404 on the skirt board base plate 403. The above-mentioned skirt board clamping member 405 is roughly a columnar structure. The skirt board clamp arranged in this way can facilitate the disassembly and assembly of the skirt board clamping member 405 and the skirt board clamping member 404, and is convenient for replacement, so that the skirt board clamp can clamp skirt boards 80 of various sizes. During specific implementation, the number of skirt board clamping members 405 on each skirt board clamping member 404 can also be specifically set according to actual production needs. Similarly, the end plate clamp can also be set with reference to the structure of the skirt board clamp, but considering that the end plate 70 is relatively thin, a simpler structure can be adopted. Please refer to Figure 2 In this embodiment, a plurality of mounting holes 309 are provided on each end plate clamping portion 304. These mounting holes 309 can be arranged radially along the end plate clamping portion 304, so that the end plate clamping parts 305 can be installed on the mounting holes 309 at different positions to form end plate clamping openings 302 of different sizes, so that the end plate clamp can clamp end plates 70 of various sizes. In specific implementation, corresponding to the number of end plate clamping parts 305 on each end plate clamping portion 304, the mounting holes 309 are arranged in two rows, that is, the two rows of mounting holes 309 are arranged radially along the end plate clamping portion 304 and include a plurality of mounting holes 309, thereby improving the clamping force.

[0070] For specific implementation, please refer to Figure 3 Threaded holes are provided on the skirt board base plate 403 and the skirt board clamping piece 404 , and the fasteners are preferably screws, which are threadedly connected to the threaded holes to lock the skirt board clamping piece 404 on the skirt board base plate 403 .

[0071] To further improve the fit of the skirt clamp, please refer to Figure 3 , 910, each skirt board clamp 401 also includes a skirt board lifting connection member 414, the skirt board clamping member 404 can be moved left and right on the skirt board lifting connection member 414 to adjust its left and right position, and then locked on the skirt board lifting connection member 414 by a fastener, and each skirt board clamp is provided with a lifting plate 406, and the lifting plate 406 is located above the skirt board base plate 403, and a plurality of lifting light rods 407 are arranged through the skirt board base plate 403 and can move up and down relative to the skirt board base plate 403, and the top of the lifting light rod 407 is fixedly connected to the top The lifting plate 406, whose bottom end is fixedly connected to the skirt lifting connector 414, is provided with a through hole for matching the lifting rod 407 and a skirt lifting cylinder 408 on the skirt base plate 403, and the fixed end of the skirt lifting cylinder 408 is installed on the skirt base plate 403, and the telescopic end is connected to the lifting plate 406, and the skirt lifting cylinder 408 drives the lifting plate 406 to move up and down, and the lifting plate 406 drives the skirt lifting connector 414 to move up and down through the lifting rod 407, thereby driving the skirt clamping member 404 to move up and down. The number of skirt lifting cylinders 408 on each skirt base plate 403 is set to two to achieve the smooth lifting of the lifting plate 406, and of course, it can also be specifically set according to actual production needs.

[0072] For specific implementation, please refer to Figure 3 The skirt board clamping mechanism includes two skirt board clamping cylinders, which are respectively connected to two skirt board clamping hands 401. The two skirt board clamping cylinders respectively drive the two skirt board clamping hands 401 to move in a direction away from or close to each other (X-axis direction), thereby realizing the opening or closing function of the two skirt board clamping hands 401.

[0073] See also Figure 3 The skirt board feeding drive mechanism 400 includes a skirt board screw 409 and a skirt board screw motor 410, wherein the skirt board clamping mechanism slides on the horizontal guide device 50 through a skirt board slide 411 and is connected to the two skirt board clamps 401, and the output shaft of the skirt board screw motor 410 is connected to the skirt board screw 409 and drives the skirt board screw 409 to rotate; the skirt board screw 409 is connected with the skirt board slide 411, so when the skirt board screw 409 rotates, it can drive the skirt board slide 411 to move along the length direction (X-axis direction) of the frame 20, and the skirt board slide 411 is moved upward. The skirt board clamping mechanism then drives the two skirt board clamps 401 to move, that is, the skirt board slide 411, the two skirt board clamping cylinders (not shown in the figure) and the two skirt board clamps 401 form a movable whole, which can slide as a whole on the horizontal guide device 50, so that the skirt board clamp can move in the length direction (X-axis direction) of the frame 20 to achieve effective transportation of the skirt board 80, and the skirt board clamping cylinder on the skirt board slide 411 then drives the two skirt board clamps 401 to move relative to each other, and the clamping and loosening of the skirt board 80 are achieved by changing the relative distance between the two skirt board clamps 401.

[0074] For specific implementation, please refer to Figure 2The horizontal guide device 50 can be a slide rail or other guide devices such as a guide rod 109.

[0075] See also Figure 1 , 3 When the skirt board 80 is transferred to the skirt board clamping part 404, the two skirt board clamping cylinders drive the two skirt board grippers 401 to close until the two skirt board clamping parts 405 clamp the skirt board 80 from the periphery, and then the skirt board screw motor 410 drives the skirt board screw 409 to rotate, and the skirt board screw 409 drives the skirt board slide 411 to move above the end plate 70 on the chassis 101, and the skirt board lifting cylinder 408 pulls the skirt board lifting connecting part 414 downward, thereby driving the skirt board clamping part 404 to move downward until the skirt board 80 is installed on the end plate 70, and then the skirt board clamping cylinder extends to drive the distance between the two skirt board base plates 403 to increase, and the skirt board clamping part 405 releases the skirt board 80, so that the skirt board 80 is installed on the end plate 70. The skirt board feeding device 40 stops here and waits for material collection.

[0076] In this example, see Figure 4 The above-mentioned loading device also includes a loading conveying mechanism and a lifting device, wherein the loading conveying mechanism is preferably a loading conveying roller, the loading conveying roller includes an end plate loading conveying roller 310 and a skirt plate loading conveying roller 412, the lifting device includes an end plate lifting device 311, a skirt plate lifting device 413 and a shell covering the outside of the two, specifically, the end plate loading conveying roller 310 is located below the end plate fixture and is used to convey the end plate 70 toward the chassis 101 direction (X-axis direction), and the end plate lifting device 311 is used to drive the end plate loading conveying roller The end plate 70 on the cylinder 310 moves toward or away from the end plate clamp (X-axis direction) so that the end plate clamp can clamp the end plate 70 on the end plate feeding conveying roller 310; the skirt plate feeding conveying roller 412 is located below the skirt plate clamp and is used to convey the skirt plate 80 toward the chassis 101 direction (X-axis direction), and the skirt plate lifting device 413 is used to drive the skirt plate 80 on the skirt plate feeding conveying roller 412 to move toward or away from the skirt plate clamp (X-axis direction) so that the skirt plate clamp can clamp the skirt plate 80 on the skirt plate feeding conveying roller 412. More specifically, the end plate feeding conveying roller 310 and the skirt plate feeding conveying roller 412 each include a plurality of conveying rollers, which are spaced apart to form a lifting channel, and the end plate lifting device 311 and the skirt plate lifting device 413 each include a lifting mechanism and a plurality of lifting parts, please refer to Fig.11 The above-mentioned lifting members correspond to the positions of the lifting channels. When the lifting mechanism drives the lifting members connected thereto to rise, these lifting members can pass through the lifting channels and lift the end plate 70 or skirt plate 80 on the conveying roller so that the end plate clamp or skirt plate clamp can take the plate.

[0077] Specifically, the lifting mechanism is preferably an oil cylinder, but it can also be a driving component such as a pneumatic cylinder.

[0078] During the work, please refer to Figure 1 , 4 , the end plate 70 is placed on the end plate feeding conveying roller 310 on the left side, the end plate feeding conveying roller 310 starts and conveys the end plate 70 to the end plate lifting device 311, the end plate lifting device 311 starts and drives the end plate 70 to be lifted to a position below the end plate clamp where it can be clamped. Similarly, the skirt board 80 is placed on the skirt board feeding conveying roller 412 on the right side, the skirt board feeding conveying roller 412 starts and conveys the skirt board 80 to the skirt board lifting device 413, the skirt board lifting device 413 starts and drives the skirt board 80 to be lifted to a position below the skirt board clamp where it can be clamped.

[0079] Specifically, see Figure 1 , 2 The end plate feeding device 30 further includes a positioning plate 312 and a positioning mechanism. The positioning plate 312 can move along the height direction (Z-axis direction) of the frame 20. The positioning mechanism is used to drive the positioning plate 312 to move in the height direction (Z-axis direction) of the frame 20 so that the positioning plate 312 can contact the end plate 70 on the end plate feeding conveying roller 310 when the end plate feeding conveying roller 310 is close to the end plate clamp, thereby limiting the remaining end plates 70 from being conveyed to the bottom of the end plate clamp, thereby enabling the end plate clamp to only clamp one end plate 70 at a time. Of course, the skirt plate feeding device 40 can also be provided with a corresponding positioning plate 312 and a positioning mechanism so that the skirt plate clamp can only clamp one skirt plate 80 at a time.

[0080] During specific implementation, the positioning mechanism is preferably a cylinder, but it can also be a driving component such as an oil cylinder or a motor.

The unloading device 60 includes a unloading conveying mechanism and a picking device 601. The unloading conveying mechanism is arranged along the width direction (Y-axis direction) of the frame 20, that is, the unloading conveying mechanism conveys the welding workpiece along the width direction (Y-axis direction) of the frame 20. The skirt board clamp takes the welded welding workpiece out from the chassis 101 and sends it to the picking device 601. The picking device 601 is lifted to the skirt board clamp to take the material and then descends to move the welding workpiece to the unloading conveying mechanism, and the unloading conveying mechanism outputs the welding workpiece.

[0082] Specifically, see Figure 1 , 4 The unloading conveying mechanism is preferably an unloading conveying roller 600. The structures of the unloading conveying roller 600 and the material taking device 601 are substantially the same as the above-mentioned end plate unloading conveying roller 310 and end plate lifting device 311 (skirt plate unloading conveying roller 412 and skirt plate lifting device 413).

[0083] Embodiment 2:

[0084] The main difference between this embodiment and embodiment 1 is that:

[0085] See also Fig.12 The welding device also includes a safety device, which can interfere with the movement trajectory of the pressure plate connecting plate 103 to limit the pressure plate 102 from moving up and down on the chassis 101, that is, to limit the pressure plate connecting plate 103 from moving up and down along the guide rod 109. Specifically, the safety device includes a safety limiter 124, a safety mating member 125 and a safety limiter driving mechanism 126. The safety mating member 125 is installed on the pressure plate connecting plate 103 and has a mating hole. The fixed end of the safety limiter driving mechanism 126 is fixed On the top plate 110, the safety limiter 124 is the output shaft of the safety limiter driving mechanism 126. When the pressure plate 102 is not working or under maintenance, the pressure plate driving mechanism 104 drives the pressure plate connecting plate 103 to rise to a preset position close to the top plate 110, and the safety limiter driving mechanism 126 drives its output shaft to be ejected and assembled with the matching hole of the safety matching member 125 on the pressure plate connecting plate 103, thereby locking the pressure plate connecting plate 103 at this height to prevent the pressure plate connecting plate 103 from falling and hitting people. Of course, the installation positions of the safety matching member 125 and the safety limiter driving mechanism 126 can be interchanged.

[0086] In other embodiments, the installation positions of the safety fitting 125 and the safety limit driving mechanism 126 may also be set on the guide rod 109 and the pressure plate connecting plate 103 .

One end of the two end plate pull rods 314 is symmetrically rotatably connected to the end plate push plate 313, and the other end is respectively rotatably connected to an end plate clamping hand 301. One end of the end plate clamping cylinder 315 is connected to the end plate slide 308, and the other end is connected to one of the end plate clamping hands 301. The end plate clamping cylinder 315 drives the left end plate clamping hand 301 by telescopic movement, so that the distance between the end plate clamping hand 301 and the end plate slide 308 changes. At the same time, an end plate pull rod 314 connected to the left end plate clamping hand 301 drives the end plate push plate 313 to rotate, thereby driving the right end plate clamping hand 301 connected to it through the other end plate pull rod 314, so as to realize the opening or closing function of the two end plate clamping hands 301.

[0088] See also Fig.12The skirt board clamping mechanism is similar to the above-mentioned end board clamping mechanism, which includes a skirt board push plate, two skirt board pull rods and a skirt board clamping cylinder. The skirt board push plate is rotatably arranged on the skirt board slide 411. One end of the two skirt board pull rods is symmetrically rotatably connected to the skirt board push plate, and the other end is respectively rotatably connected to a skirt board clamp 401. One end of the skirt board clamping cylinder is connected to the skirt board slide 411, and the other end is connected to one of the skirt board clamps 401. The skirt board clamping cylinder drives the left skirt board clamp 401 by telescopic movement, so that the distance between the skirt board clamp 401 and the skirt board slide 411 changes. At the same time, a skirt board pull rod connected to the left skirt board clamp 401 drives the skirt board push plate to rotate, thereby driving the right skirt board clamp 401 connected to it through another skirt board pull rod, so as to realize the opening or closing function of the two skirt board clamps 401.

[0089] See also Figure 14-17 Similar to the chassis 101, a leakage hole is also provided on the bottom surface of the pressure plate 102, which can reduce the weight of the pressure plate 102 and provide more margin for elastic deformation.
