[0001] The present invention relates to the technical field of welding equipment, in particular to a laser cutting and welding machine. Background Art

[0002] When producing cold-rolled steel coils, the head of a sheet needs to be welded to the tail of another sheet. Existing welding equipment generally includes a first sheet conveying mechanism, a second sheet conveying mechanism, a clamping mechanism, and a welding mechanism. The first sheet conveying mechanism conveys the first sheet to the workstation to be welded, and then the second sheet conveying mechanism conveys the second sheet to the workstation to be welded. The two sheets are clamped and fixed by the clamping mechanism, and then the welding mechanism set at the workstation to be welded welds the head of the sheet to the tail of the other sheet together. In order to ensure the welding performance of the two sheets, the above structure is generally only applicable to sheets with thicker thickness and spliced ​​welding, that is, the two sheets are horizontally close to each other, but is not applicable to the stacking welding of two thinner sheets, that is, the two sheets are stacked up and down, which reduces the applicability of the welding equipment.

DETAILED DESCRIPTION

[0046] The present invention provides a laser cutting and welding machine. To make the objectives, technical solutions, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0047] In this embodiment, the direction of the X-axis is the same as the front-back direction, the direction of the Y-axis is the same as the left-right direction, and the direction of the Z-axis is the same as the up-down direction.

[0048] See also Figure 1 and Figure 10The present invention provides a laser cutting and welding machine, comprising a base frame 100, a front auxiliary material setting device B, a movable matching device C and a rear auxiliary material setting device D arranged on the base frame 100 in sequence from front to back; the movable matching device C comprises a front feeding seat C1, a front swing mechanism C2 arranged on the front feeding seat C1, a rear feeding seat C3, a rear swing mechanism C4 arranged on the rear feeding seat C3 and a matching driving mechanism C5 that drives the front feeding seat C1 and the rear feeding seat C3 to move closer to or away from each other; the front swing mechanism C2 is provided with a front sheet metal automatic positioning device E and the front swing mechanism C2 is used to pull the front sheet material automatic positioning device E to tilt downward or reset upward, and the rear sheet material automatic positioning device F is provided on the rear swing mechanism C4 and the rear swing mechanism C4 is used to pull the rear sheet material automatic positioning device F to tilt downward or reset upward; a sheet material cutting and welding device G is also provided above the front sheet material automatic positioning device E and the rear sheet material automatic positioning device F; the front sheet material automatic positioning device E and the front auxiliary material setting device B are respectively used to clamp or separate the front sheet material, and the rear sheet material automatic positioning device F and the rear auxiliary material setting device D are used to clamp or separate the rear sheet material.

[0049] When two sheets of equal thickness and thickness greater than 1.0 mm are spliced ​​and welded, the operation mode is as follows: the rear sheet is transported from the rear to the front, passes through the rear auxiliary material setting device D, the rear sheet automatic positioning device F, the front sheet automatic positioning device E and the front auxiliary material setting device B in sequence, and then the sensor assembly is triggered, and then it is transported from the front to the rear. After being transported for a certain distance, the rear sheet is clamped by the rear sheet automatic positioning device F and the rear auxiliary material setting device D, and then the sheet cutting and welding device G is operated to cut off the edge of the head of the rear sheet; while the sheet cutting and welding device G is operating, the front sheet is transported from the front to the rear, and after being transported for a certain distance, the front sheet is clamped by the front sheet automatic positioning device E and the front auxiliary material setting device B, and then the sheet cutting and welding device G is operated to cut off the edge of the head of the rear sheet. After the tail edge of the sheet is cut and both sheets are cut, the front auxiliary material setting device B and the rear auxiliary material setting device D release the clamping of the front sheet or the rear sheet. Then the drive mechanism C5 is operated, causing the front feed base C1 to move backward and the rear feed base C3 to move forward, driving the front sheet automatic positioning device E and the rear sheet automatic positioning device F to approach each other until the tail of the front sheet and the head of the rear sheet touch each other. Then the sheet cutting and welding device G is operated to weld the contact position of the front and rear sheets. After welding is completed, the sheet cutting and welding device G is reset, and the front sheet automatic positioning device E and the rear sheet automatic positioning device F release the clamping of the front and rear sheets respectively. Then the front and rear sheets are transported to the rear, completing the cutting and welding of the front and rear sheets. In continuous production, the sheet that has become longer after welding is used as the rear sheet and the above operation mode is repeated, thereby continuously increasing the length of the cold-rolled steel coil.

[0050] Two plates of equal thickness and less than 1.0 mm or of unequal thickness and less than 1.0 mm are stacked and welded. Stacking welding is divided into front stacking (i.e., the front plate is stacked on top of the rear plate) and rear stacking (i.e., the front plate is stacked below the rear plate). The rear stack is taken as an example for description here. The actions of the front plate and the rear plate before welding are the same as those of splicing welding. Before the rear plate and the front plate are aligned after cutting, the front auxiliary material setting device B runs to clamp the front plate. At this time, the front plate automatic positioning device E and the rear plate automatic positioning device F are both in the open state. Then the front swing mechanism C2 runs to lift the front side of the front plate automatic positioning device E, so that the rear side thereof tilts downward, causing misalignment with the rear plate automatic positioning device F. Then the alignment drive mechanism C5 runs to move the front feeding seat C1 and the rear Driven by the feeding seat C3, the front sheet material automatic positioning device E and the rear sheet material automatic positioning device F are brought close to each other. After they are aligned, the rear sheet material is located above the front sheet material, and then the front sheet material automatic positioning device E is operated (the front auxiliary material setting device B is reset), clamping the front sheet material and the rear sheet material at the same time. After clamping in place, the front swing mechanism C2 is reset, driving the front sheet material automatic positioning device E to reset upward (that is, it is in a horizontal state again), and the rear sheet material automatic positioning device F clamps the rear sheet material, and then the front auxiliary material setting device B and the rear auxiliary material setting device D clamp the front sheet material and the rear sheet material respectively, and finally trigger the sheet material cutting and welding device G to weld the front sheet material and the rear sheet material. Stacking welding requires the sheet material cutting and welding device G to move back and forth once, that is, first move to the left and then to the right, or first move to the right and then to the left.

[0051] The operation mode of front stacking and rear stacking is basically the same. The difference is that the rear side of the rear plate automatic positioning device F is lifted by the rear swing mechanism C4, so that its front side is tilted downward, and then the front plate is sent to the rear plate automatic positioning device F. The rear plate automatic positioning device F clamps the front plate and the rear plate at the same time and then resets them upward.

[0052] The matching laser cutting and welding machine is suitable for cold-rolled steel coils with a width of 1.0-1.5m and a thickness of 0.3-3.5mm. It has a simple structure and strong practicality. By setting the front auxiliary material setting device B and the rear auxiliary material setting device D, the front plate and the rear plate are assisted in clamping, thereby improving the clamping effect of the plate; by setting the plate cutting and welding device G, it is used to cut and weld the edges of the two plates; by setting the matching drive mechanism C5, the front plate automatic positioning device E and the rear plate automatic positioning device F are made to approach or move away from each other; by setting the front swing mechanism C2 and the rear swing mechanism C4, in cooperation with the front plate automatic positioning device E and the rear plate automatic positioning device F, the front stacking welding and rear stacking welding of the two plates are realized.

[0053] See also Figure 1-Figure 3Furthermore, the front sheet material automatic positioning device E and the rear sheet material automatic positioning device F are symmetrically arranged, and the front sheet material automatic positioning device E and the rear sheet material automatic positioning device F each include an upper pressing clamp F1, a lower pressing clamp F2 arranged below the upper pressing clamp F1, and a clamping mechanism F3 arranged on the lower pressing clamp F2, the clamping mechanism F3 is used to make the upper pressing clamp F1 and the lower pressing clamp F2 contact or separate; a clamping induction group is also provided between the upper pressing clamp F1 and the lower pressing clamp F2 Part F6, the clamping sensing component F6 includes a mounting plate F61 connected to the side wall of the lower pressure clamp F2, the mounting plate F61 is provided with a waist-shaped hole F62 extending along its height direction, three clamping sensors F63 are provided in the waist-shaped hole F62, and a sensing plate F64 is provided on the side wall of the upper pressure clamp F1, the three clamping sensors F63 are respectively used to sense the sensing plate F64, and the three clamping sensors F63 are respectively electrically connected to the clamping mechanism F3.

[0054] In this embodiment, the distance between the clamping sensors F63 located at the top and the bottom is the maximum moving stroke of the upper clamp F1. When the clamping sensor F63 located at the top senses the sensing plate F64, the distance between the upper clamp F1 and the lower clamp F2 is the largest (in the fully open state). When the clamping mechanism F3 operates to drive the upper clamp F1 and the sensing plate F64 to move downward, until the clamping sensor F63 located in the middle senses the sensing plate F64, it is a single clamping (half-open state). At this time, the distance between the upper clamp F1 and the lower clamp F2 becomes smaller, and then the side edge mechanism F4 operates to perform the edge positioning operation of the sheet material, and then the clamping mechanism F3 operates again to make the upper clamp F1 continue to move downward. This is the secondary clamping. At this time, the clamping sensor F63 located at the bottom senses the sensing plate F64, and the upper clamp F1 and the lower clamp F2 are in a completely closed state. The above arrangement enables the front sheet material automatic positioning device E and the rear sheet material automatic positioning device F to have three different states (fully open state, primary clamping, secondary clamping), providing space for the sheet material to pass through and position the opposite edges of the sheet material.

[0055] See also Figure 1 、 Figure 2 、 Figure 6-Figure 8Furthermore, the lower surface of the upper pressing clamp F1 and the upper surface of the lower pressing clamp F2 are both provided with tooth plates F21, and the two tooth plates F21 are on the same vertical extension line. The upper surface of the upper pressing clamp F1 is also provided with an upper fixed edge mechanism F7, and the upper fixed edge mechanism F7 includes a fixed edge driving member F71, a connecting plate F72, a positioning plate F73, a positioning guide rod F74 and a fixed edge block F75; the output end of the fixed edge driving member F71 is set downward, and passes through the connecting plate F72 and is connected to the upper edge of the upper pressing clamp F1. Surface connection, the positioning guide rod F74 passes through the upper and lower surfaces of the upper pressing clamp F1, and its upper end face is connected to the lower surface of the connecting plate F72, and its lower end face is connected to the upper surface of the positioning plate F73, and a fixed edge block F75 is provided on the side wall of the positioning plate F73. There are two or more tooth plates F21 provided on the upper pressing clamp F1, and the fixed edge block F75 is provided between adjacent tooth plates F21. The side wall of the fixed edge block F75 contacts or separates from the head or tail of another sheet material.

[0056] See also Figure 2 Furthermore, a supporting plate F22 is provided on the upper surface of the lower pressing clamp F2, and one or more supporting plates F23 are provided between the tooth plate F21 and the supporting plate F22.

[0057] The tooth plate F21, the support plate F22 and the supporting plate F23 are all used to support the front plate or the rear plate, so that there is a certain distance between the plate and the upper surface of the lower pressure clamp F2, providing space for the setting of the side-to-edge mechanism F4 and enabling the upper and lower tooth plates F21 to clamp the plate when they come into contact. The above-mentioned upper edge fixing mechanism F7 is only operated when stacking and welding is being performed. Here, its operation mode is described by taking the front stack as an example. The actions before welding and matching the front and rear plates are the same as above, that is, the rear plate automatic positioning device F is in a one-time clamping state, the rear auxiliary fixing device D is operated, and the output end of the edge fixing drive member F71 is contracted, driving the connecting plate F72, the positioning plate F73, the positioning guide rod F74 and the edge fixing block F75 to move downward, and clamp the rear plate, and then the rear swing mechanism C4 is operated to tilt the front side of the rear plate automatic positioning device F downward, causing misalignment with the front plate, and then after matching in place, the front plate automatic positioning device E is opened to a one-time clamping state, and then the front plate is transported backward until the side of the front plate is The edge contacts the front side wall of the fixed edge block F75. The setting of the fixed edge block F75 limits the moving stroke of the front sheet. Then the side edge mechanism F4 positions the sheet against the edge, and then the rear sheet automatic positioning device F clamps it for the second time. Since the tooth plate F21 is set on both the upper pressing clamp F1 and the lower pressing clamp F2, the front sheet and the rear sheet are clamped at the same time by the tooth plate F21. Then the upper fixed edge mechanism F7 is reset (that is, the upper surface of the positioning plate F73 contacts the lower surface of the upper pressing clamp F1), the rear swing mechanism C4 is reset (even if the rear sheet automatic positioning device F is in a horizontal state again), the front sheet automatic positioning device E clamps it for the second time, and finally the sheet cutting and welding device G is triggered to open the gap between the teeth on the tooth plate F21 ( Figure 9 The M area is the weld, O represents the front sheet, and P represents the rear sheet) in which the front sheet and the rear sheet are welded by spot welding. The back stacking method is basically the same as the steps of the front stacking, except that it is the front sheet automatic positioning device E that is tilted downward, and the rear sheet is transported from the rear to the front to the top of the front sheet automatic positioning device E, and then the front sheet automatic positioning device E clamps the front sheet and the rear sheet at the same time. Through the above-mentioned setting, the laser cutting and welding machine can limit the side edge of the front sheet or the side edge of the rear sheet when stacking and welding, so as to prevent the welding position of the front sheet or the rear sheet from being completely covered by the rear sheet automatic positioning device F or the front sheet automatic positioning device E, thereby hindering the welding process.

[0058] See also Figure 6-8Furthermore, the fixed edge driving member F71 is an oil cylinder; the connecting plate F72 is also provided with an emergency cylinder F76 with an output end facing downward, and the output end of the emergency cylinder F76 contacts or separates from the upper surface of the upper pressure clamp F1. The oil cylinder has a strong load-bearing capacity. When the oil cylinder fails, the connecting plate F72 loses the supporting force of the oil cylinder, and due to the action of gravity, it will drive the positioning guide rod F74, the positioning plate F73, and the fixed edge block F75 to move downward, thereby affecting the passage of the sheet material between the upper pressure clamp F1 and the lower pressure clamp F2. By setting up an emergency cylinder F76, when the oil cylinder fails, the emergency cylinder F76 is started, and the output end is extended and contacted with the upper surface of the upper pressure clamp F1 through the action of the air source, and then the connecting plate F72 is lifted, thereby driving the positioning guide rod F74, the positioning plate F73 and the fixed edge block F75 to rise, so that the upper surface of the positioning plate F73 contacts the lower surface of the upper pressure clamp F1, which will not hinder the passage of the sheet material, so that the sheet material can continue to be produced or the fixed edge drive component F71 can be repaired.

[0059] See also Figure 5 Furthermore, an oil inlet pipe F11 and an oil outlet pipe F12 are provided on the side wall of the upper clamp F1. Both the oil inlet pipe F11 and the oil outlet pipe F12 are equipped with a first valve F13. The oil cylinder is connected to the oil inlet pipe F11 or the oil outlet pipe F12. The oil inlet pipe F11 is connected to the oil inlet end of the oil cylinder, and the oil outlet pipe F12 is connected to the oil outlet end of the oil cylinder. Opening the first valve F13 drains the hydraulic oil from the oil inlet pipe F11 and the oil outlet pipe F12, facilitating maintenance of the oil cylinder without affecting the passage of sheet metal.

[0060] See also Figure 2 、 Figure 4-Figure 5 Furthermore, the lower pressure clamp F2 is also provided with a side-to-side mechanism F4, which includes a side-to-side drive motor F401, a side-to-side top block F402, a side-to-side screw F403, a side-to-side bearing seat F404, a side-to-side top material push rod F405 and a side-to-side top material block F406. The output end of the side-to-side drive motor F401 is transmission-connected to the side-to-side screw F403, the side-to-side top block F402 is provided on the side-to-side screw F403, and the side-to-side top material push rod F405 is provided with a side-to-side top material push rod F406. The end of the side screw F403 is connected to the opposite side bearing seat F404, and the opposite side bearing seat F404 is arranged on the lower pressure clamp F2. The opposite side ejection push rod F405 is connected to the side wall of the opposite side ejection block F402, and its end is connected to the opposite side ejection block F406. The opposite side ejection block F406 is used to push the sheet material between the upper pressure clamp F1 and the lower pressure clamp F2. The lower pressure clamp F2 is provided with a side sensing component F5 for sensing the side of the sheet material.

[0061] In actual use, the side-to-side mechanism F4 is used to position and align the side edges of the sheet. The side-to-side mechanism F4 will only operate when the front sheet automatic positioning device E or the rear sheet automatic positioning device F is in a single clamping state. The above operation plays a certain limiting role on uneven sheets, preventing the side-to-side lifting block F406 from having no effect on the sheet. That is, in order to prevent the height of the side-to-side lifting block F406 from being set too high and affecting the clamping of the upper pressure clamp 1 and the lower pressure clamp 2, the height of the side-to-side lifting block F406 is set relatively low, and it is difficult to ensure that the side-to-side lifting block F406 is in contact with the side edge of the sheet when it is fully open.

[0062] In this embodiment, when the front or rear sheet is being cut, spliced, welded, or stacked, the side drive motor F401 is in operation, driving the side screw F403 to rotate, causing the side push block F402, side push rod F405, and side push block F406 mounted on the side screw F403 to move toward the sheet until the other side of the sheet contacts the side sensing assembly F5. The side sensing assembly F5 then receives a signal indicating that the sheet is in place through the control mechanism, which in turn transmits a signal to the side drive motor F401 to stop or reverse rotation. Through this arrangement, the cutting and welding quality of the two sheets is guaranteed.

[0063] See also Figure 2 、 Figure 6 Furthermore, the side sensing component F5 includes a first side positioning block F51, a second side positioning block F52 and a contact sensor F53; the first side positioning block F51 is arranged on the upper surface of the lower pressing clamp F2 away from the side-to-edge mechanism F4, and the second side positioning block F52 is arranged on the lower surface of the upper pressing clamp F1. The first side positioning block F51 and the second side positioning block F52 are staggered, and the contact sensor F53 is arranged on the first side positioning block F51 for contacting or separating with the side of the front plate or the rear plate.

[0064] When the upper clamp F1 moves downward, the upper surface of the first side positioning block F51 contacts the lower surface of the upper clamp F1, and the lower surface of the second side positioning block F52 contacts the upper surface of the lower clamp F2, forming a certain gap between the upper clamp F1 and the lower clamp F2, providing space for the opposite side lifting block F406 to be set between the upper clamp F1 and the lower clamp F2. The inner side walls of the first side positioning block F51 and the second side positioning block F52 are flush, which plays the role of limiting and opposite edges, so that the side of the sheet material contacts them. In actual use, after the side of the sheet material contacts the first side positioning block F51, the contact sensor F53 is triggered, causing the contact sensor F53 to switch from disconnected to connected, and then transmits the in-position signal to the control mechanism, which controls the opposite side drive motor F401 to stop rotating.

[0065] See also Figure 5 Furthermore, the side-to-side mechanism F4 also includes a side-to-side motor seat F407, a side-to-side coupling F408, a side-to-side push rod guide sleeve F409 and a side-to-side connecting column F410; the side-to-side drive motor F401 is arranged on the side-to-side motor seat F407, and the output end of the side-to-side drive motor F401 is connected to one end of the side-to-side coupling F408, and the other end of the side-to-side coupling F408 is connected to the side-to-side screw F403; the side-to-side push rod guide sleeve F409 is arranged on the upper surface of the lower pressure clamp F2, and the side-to-side ejecting push rod F405 passes through the left and right side walls of the side-to-side push rod guide sleeve F409; one end of the side-to-side connecting column F410 sequentially passes through the side-to-side motor seat F407 and the side-to-side ejecting block F402, and the lower end surface of the other end thereof is connected to the upper surface of the lower pressure clamp F2. The side push rod guide sleeve F409 and the side connecting column F410 are provided to improve the stability of the side motor base F407 and the side ejector block F402, thereby improving the movement smoothness of the side ejector block F406.

[0066] See also Figure 5 Furthermore, a side groove F4061 is provided on the side wall of the edge-push block F406, away from the edge-push drive motor F401. The side edge of the sheet metal is positioned within this groove F4061. The sheet metal on the lower clamp F2 is supported by the support plate F22 and the tooth plate F21. During the movement of the edge-push block F406, the groove F4061 increases the contact area between the edge-push block F406 and the side edge of the sheet metal and serves to limit the sheet metal's position, preventing it from shifting during the pushing process.

[0067] See also Figure 5 Furthermore, the clamping mechanism F3 includes a clamping drive seat F31, a hydraulic cylinder F32 with an output end facing upward, a guide column F33 and a guide column cover F34; the clamping drive seat F31 is connected to the lower surface of the lower pressure clamp F2, the hydraulic cylinder F32 is arranged on the clamping drive seat F31, and its output end is connected to the lower surface of the guide column F33, the guide column F33 passes through the upper and lower surfaces of the upper pressure clamp F1 and the upper and lower surfaces of the lower pressure clamp F2, and its upper part is connected to the guide column cover F34, and the lower surface of the guide column cover F34 abuts against the upper surface of the upper pressure clamp F1. In actual use, the output end of the hydraulic cylinder F32 is extended to lift the guide column F33 and the upper pressure clamp F1, so that the upper pressure clamp F1 and the lower pressure clamp F2 are separated; the output end of the hydraulic cylinder F32 is contracted to drive the guide column F33 and the upper pressure clamp F1 downward, so that the upper pressure clamp F1 and the lower pressure clamp F2 are in contact. The hydraulic cylinder F32 has a strong load-bearing capacity and good stability.

[0068] See also Figure 5 Furthermore, an oil inlet pipe F11 and an oil outlet pipe F12 are provided on the sidewall of the lower clamp F2, each of which is equipped with a first valve F13. The hydraulic cylinder F32 is connected to the oil inlet pipe F11 or the oil outlet pipe F12. This arrangement facilitates the discharge of hydraulic oil from the hydraulic cylinder F32 through the pipes.

[0069] See also Figure 5 Furthermore, emergency threaded holes are provided on each end of the upper clamp F1, into which emergency screws F14 are threadedly connected. Blind holes F24 are provided on each end of the lower clamp F2, corresponding to the locations of the emergency threaded holes. Similarly, if the hydraulic cylinder F32 malfunctions, the hydraulic oil within it is drained, and the emergency screws F14 are rotated to open or close the upper clamp F1, allowing sheet metal to pass through, facilitating continued sheet metal production or repairing components in the clamping mechanism F3.

[0070] See also Figure 10 、 Figure 11 Furthermore, the front swing mechanism C2 and the rear swing mechanism C4 are symmetrically arranged, and both the front swing mechanism C2 and the rear swing mechanism C4 include a swing driving member C41 and two swing supporting seats C42; the swing driving member C41 includes a swing hydraulic cylinder C411, a swing driving member mounting seat C412 and a swing top block C413, the swing driving member mounting seat C412 is arranged on the side wall away from the rear feeding seat C3 or the front feeding seat C1, the swing hydraulic cylinder C411 is arranged on the swing driving member mounting seat C412, the swing hydraulic cylinder C411 is arranged on the swing driving member mounting seat C412, and the swing hydraulic cylinder C411 is arranged on the swing driving member mounting seat C412. The output end of the cylinder C411 is rotatably connected to the swing top block C413, and the upper surface of the swing top block C413 is connected to the lower surface of the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F; the two swing support seats C42 are respectively arranged at the two ends of the front feeding seat C1 or the rear feeding seat C3, and the two swing support seats C42 rotate when following the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F to tilt downward, and rotate in the opposite direction when following the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F to reset upward.

[0071] In actual use, the front swing mechanism C2 and the rear swing mechanism C4 do not operate during splicing welding, and only operate during stacking welding. Taking the back stacking as an example, its specific operation mode is: before the front feeding seat C1 and the rear feeding seat C3 are matched, the output end of the swing hydraulic cylinder C411 on the front feeding seat C1 extends, driving the swing top block C413 to rise, lifting the front side of the front plate automatic positioning device E, and making the rear side of the front plate automatic positioning device E tilt downward by a certain angle, and then the swing supporting seat C42 is driven by the front plate automatic positioning device E to rotate toward the direction of the rear plate automatic positioning device F, so as to make the front plate automatic positioning device E tilt downward smoothly and limit it, and then the rear plate is transported to the front plate automatic positioning device E, and the moving stroke of the rear plate is limited by the upper edge fixing mechanism F7, and then the front plate automatic positioning device E operates to clamp the front plate and the rear plate, and then the output end of the swing hydraulic cylinder C411 contracts, driving the swing top block C413 to descend, and the swing supporting seat C42 rotates in the opposite direction, so that the front plate automatic positioning device E is reset upward. The above-mentioned arrangement has a simple structure. A swing driving component C41 is provided to lift the front side of the front plate automatic positioning device E or the rear side of the rear plate automatic positioning device F. A swing supporting seat C42 is provided to support the front plate automatic positioning device E or the rear plate automatic positioning device F and to limit the front plate automatic positioning device E or the rear plate automatic positioning device F respectively.

[0072] See also Figure 11Furthermore, the swing supporting seat C42 includes a supporting bracket C421, a swing frame C422, a swing shaft C423 and a swing top plate C424; the supporting bracket C421 is arranged on the upper surface of the front feeding seat C1 or the rear feeding seat C3, the swing frame C422 is arranged inside the supporting bracket C421, and the two ends of the swing shaft C423 pass through the left and right sides of the supporting bracket C421 and the swing frame C422. The upper surface of the swing frame C422 is provided with the swing top plate C424, and the upper surface of the swing top plate C424 is connected to the lower surface of the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F. In actual use, the swing top plate C424 is used to support the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F. When the swing hydraulic cylinder C411 rises, the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F tilts downward, driving the swing frame C422 and the swing top plate C424 to rotate around the swing axis C423, so that the swing frame C422 and the top plate C424 rotate toward the direction of the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F; when the swing hydraulic cylinder C411 descends, the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F resets upward, driving the swing frame C422 and the swing top plate C424 to rotate away from the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F (i.e., reverse rotation), so that the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F is back to a horizontal state.

[0073] See also Figure 11 Furthermore, the supporting bracket C421 includes two first support plates C4211 and a second support plate C4212 connecting the two ends of the two first support plates C4211; the upper parts of the two first support plates C4211 are both provided with chamfers, and the height of the second support plate C4212 is less than the height of the first support plate C4211; the swing frame C422 includes two third support plates C4221 and a fourth support plate C4222 arranged between the two third support plates C4221; the lower parts of the two third support plates C4221 are both provided with chamfers, and the inclination angle of the chamfer on the third support plate C4221 is greater than the inclination angle of the chamfer on the first support plate C4211. By setting chamfers on the upper part of the first support plate C4211 and the lower part of the third support plate C4221 and limiting the height of the second support plate C4212, space is provided for the rotation of the third support plate C4221 when the front plate automatic positioning device E or the rear plate automatic positioning device F tilts downward or resets upward, thereby preventing interference.

[0074] See also Figure 11Furthermore, an angle adjustment mechanism C6 is provided on the inner side wall of the supporting bracket C421, and the angle adjustment mechanism C6 includes two angle adjustment seats C61 and two adjustment screws C62; the two angle adjustment seats C61 are respectively arranged along the front and rear directions of the base frame 100, and each of the angle adjustment seats C61 is provided with an adjustment threaded hole, and the adjustment screw C62 is threadedly connected to the corresponding adjustment threaded hole.

[0075] In actual use, the swing angle of the front sheet metal automatic positioning device E or the rear sheet metal automatic positioning device F is adjusted by adjusting the height of the two adjustment screws C62 relative to the angle adjustment base C61. The operation of the angle adjustment mechanism C6 is described below using the angle adjustment mechanism C6 located on the front feed base C1 as an example. The adjustment screw C62 located near the rear sheet metal automatic positioning device F is screwed into the angle adjustment base C61, shortening the protrusion of the adjustment screw C62 from the angle adjustment base C61. When the front sheet metal automatic positioning device E tilts downward, the protrusion of the adjustment screw C62 decreases, thereby increasing the downward tilt angle of the front sheet metal automatic positioning device E. Conversely, when the adjustment screw C62 protrudes from the angle adjustment base C61 longer, the downward tilt angle of the front sheet metal automatic positioning device E decreases. Similarly, when the adjusting screw C62 away from the rear sheet metal automatic positioning device F is screwed into the angle adjustment seat C61, the length of the adjusting screw C62 protruding from the angle adjustment seat C61 becomes shorter, and when the front sheet metal automatic positioning device E resets upward, its tilt angle becomes larger. It should be noted here that when the length of the adjusting screw C62 protruding from the angle adjustment seat C61 away from the rear sheet metal automatic positioning device F is too short, the front sheet metal automatic positioning device E is likely to tilt upward to a certain angle, which may easily bend the rear sheet metal when clamping the two sheets; and when the adjusting screw C62 protruding from the angle adjustment seat C61 is too long, the front sheet metal automatic positioning device E is likely to still tilt downward after reset, and after clamping the two sheets, it may affect the sheet metal cutting and welding device G's ability to weld the two sheets. Therefore, through the above arrangement, on the one hand, it serves to support and limit the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F when it tilts downward or resets upward; on the other hand, it is convenient to fine-tune the angle of the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F according to actual usage, so that the position of the sheet material inserted into the front sheet material automatic positioning device E or the rear sheet material automatic positioning device F and the welding position are optimal.

[0076] See also Figure 11Furthermore, the inner sidewall of the support bracket C421 is provided with two vertical rocking grooves C4213, and the outer sidewalls of the two angle adjustment seats C61 are each provided with a protrusion C611, which is disposed in the corresponding rocking grooves C4213. Both the support bracket C421 and the angle adjustment seat C61 are provided with mounting holes C612, and the same connecting member is disposed in both mounting holes C612. When installing the angle adjustment seat C61, the protrusion C611 is inserted into the rocking grooves C4213 along the height direction, and then the angle adjustment seat C61 is fixed to the support bracket C421 via the connecting member. Specifically, the connecting member can be provided as a bolt and a nut threadedly connected to the bolt.

[0077] See also Figure 12 Furthermore, the mating drive mechanism C5 includes a mating drive motor C51, a first mating coupling C52, a first mating screw C53, a second mating coupling C54 and a second mating screw C55 connected in sequence; the output end of the mating drive motor C51 extends along the length direction of the base frame 100; a first mating nut seat C56 is provided on the first mating screw C53, and the upper surface of the first mating nut seat C56 is connected to the lower surface of the front feed seat C1; a second mating nut seat C57 is provided on the second mating screw C55, and the upper surface of the second mating nut seat C57 is connected to the lower surface of the rear feed seat C3; the thread of the first mating screw C53 is opposite to the thread on the second mating screw C55. In this embodiment, when the mating drive motor C51 rotates forward, it drives the first mating coupling C52, the first mating screw C53, the second mating coupling C54 and the second mating screw C55 to rotate forward. Since the threads on the first mating screw C53 and the threads on the second mating screw C55 are set in opposite directions, the first mating nut seat C56 and the second mating nut seat C57 approach each other, driving the front feed seat C1 and the rear feed seat C3 to approach each other; when the mating drive motor C51 rotates reversely, it drives the first mating coupling C52, the first mating screw C53, the second mating coupling C54 and the second mating screw C55 to rotate reversely, so that the first mating nut seat C56 and the second mating nut seat C57 approach each other, driving the front feed seat C1 and the rear feed seat C3 away from each other. The above arrangement enables the front feeding seat C1 and the rear feeding seat C3 to move simultaneously and share the same alignment drive mechanism C5 , resulting in high synchronization and facilitating accurate alignment of the front feeding seat C1 and the rear feeding seat C3 .

[0078] See also Figure 10Furthermore, the upper surface of the base frame 100 is provided with a mating guide rail 101 along its length. The mating guide rail 101 is provided with two or more mating sliders 102 that cooperate therewith. The upper surface of the mating sliders 102 is connected to the lower surface of the front feed seat C1 or the rear feed seat C3. The middle portion of the front feed seat C1 or the rear feed seat C3 is connected to the first mating nut seat C56 and the second mating nut seat C57 respectively. By providing the mating sliders 102, the two ends of the front feed seat C1 or the rear feed seat C3 are respectively connected to the corresponding mating sliders 102. The mating sliders 102 cooperate with the mating guide rail 101 to ensure smooth movement of the front feed seat C1 or the rear feed seat C3.

[0079] See also Figure 12 Furthermore, a balancing cylinder 104 is provided on the inner side wall of the base frame 100. The output end of the balancing cylinder 104 extends along the length direction of the base frame 100, and its output end is connected to the lower surface of the front feed seat C1 or the rear feed seat C3. In actual use, when the front feed seat C1 or the rear feed seat C3 are close to each other, the output ends of the two relatively arranged groups of balancing cylinders 104 are synchronously extended; when the front feed seat C1 or the rear feed seat C3 are away from each other, the output ends of the two relatively arranged groups of balancing cylinders 104 are synchronously contracted. By providing the balancing cylinder 104, it is used to prevent the front sheet material automatic positioning device E connected to the front feed seat C1 and the rear sheet material automatic positioning device F connected to the rear feed seat C3 from starting and stopping jitter when the front feed seat C1 or the rear feed seat C3 are aligned.

[0080] See also Figure 10 、 Figure 12Furthermore, a sensing block C11 is provided on the side wall of the front feeding seat C1, and a position sensing component 103 for sensing the sensing block C11 is provided on the side wall of the base frame 100. The position sensing component 103 includes a first position sensor 1031, a first zero position sensor 1032 and a second position sensor 1033. The distance between the first position sensor 1031 and the second position sensor 1033 is the maximum moving stroke of the front feeding seat C1 and the rear feeding seat C3. When the first zero position sensor 1032 senses the sensing block C11, the first zero position sensor 1032 transmits a signal to the control mechanism, and the control mechanism transmits the signal to the mating drive motor C51, controlling the mating drive motor C51 to stop running. At this time, the front feeding seat C1 and the rear feeding seat C3 are moved away from each other; similarly, when the second position sensor 1033 senses the sensing block C11, the second position sensor 1033 transmits a signal to the control mechanism, and the control mechanism transmits the signal to the mating drive motor C51, controlling the mating drive motor C51 to stop running. At this time, the front feeding seat C1 and the rear feeding seat C3 are moved close to each other; the first position sensor 1031 is provided to protect the front feeding seat C1 and the rear feeding seat C3. When the first zero position sensor 1032 fails, the mating drive mechanism C5 continues to run. When the first position sensor 1031 senses the sensing block C11, the mating drive motor C51 is also stopped by signal transmission. Through the above arrangement, the linkage between the components in the movable matching device C is made higher, which is conducive to improving its automation level.

[0081] See also Figure 13 Furthermore, the front auxiliary material setting device B and the rear auxiliary material setting device D are symmetrically arranged, and the front auxiliary material setting device B and the rear auxiliary material setting device D both include an auxiliary material setting frame B1, a main lifting mechanism B2, an upper pressure plate B3 and a lower pressure plate B4 arranged on the auxiliary material setting frame B1, the output end of the main lifting mechanism B2 is arranged downward, and its output end is connected to the upper pressure plate B3, the lower pressure plate B4 is arranged above the upper pressure plate B3, and the main lifting mechanism B2 is used to make the upper pressure plate B3 contact or separate from the lower pressure plate B4.

[0082] In actual use, when the front sheet material is conveyed to the front auxiliary material setting device B or the rear sheet material is conveyed to the rear auxiliary material setting device D, the main lifting mechanism B2 drives the upper pressing plate B3 to rise, so that it is located above the lower pressing plate B4, so that the front sheet material or the rear sheet material can smoothly pass through the gap between the upper pressing plate B3 and the lower pressing plate B4, and then triggers the main lifting mechanism B2 to drive the upper pressing plate B3 to press down, so that the lower surface of the upper pressing plate B3 abuts against the upper surface of the front sheet material or the rear sheet material, and the upper surface of the lower pressing plate B4 abuts against the lower surface of the front sheet material or the rear sheet material, thereby realizing the front sheet material The front sheet or the rear sheet is clamped, and at the same time, the front sheet automatic positioning device E clamps the front end of the front sheet, the front auxiliary material setting device B clamps the front end of the sheet, the rear sheet automatic positioning device F clamps the front end of the rear sheet, and the rear auxiliary material setting device D clamps the rear end of the rear sheet, and then the sheet cutting and welding device G runs to cut off or weld the edge of the rear end of the front sheet or the edge of the front end of the rear sheet; when the front sheet or the rear sheet needs to continue to move backward, the main lifting mechanism B2 and the upper pressing plate B3 are reset (i.e., move upward) to release the clamping of the front sheet or the rear sheet. Through the above arrangement, the clamping of the front and rear ends of the front sheet or the rear sheet is achieved, which is conducive to improving the clamping and positioning effect of the sheet and enabling the front sheet automatic positioning device E or the rear sheet automatic positioning device F to still clamp the front sheet or the rear sheet when it is in a single clamping state, thereby preventing the front sheet or the rear sheet from shifting.

[0083] See also Figure 13 Furthermore, the auxiliary material setting frame B1 includes an inverted L-shaped bracket B11, a horizontal beam B12, and a vertical beam B13. The inverted L-shaped bracket B11 is provided in two, and the two inverted L-shaped brackets B11 are symmetrically arranged on both sides of the lower pressing plate B4. The upper surfaces of the two inverted L-shaped brackets B11 are respectively connected to the horizontal beam B12. The vertical beams B13 are respectively provided on the inner side walls of the two inverted L-shaped brackets B11. The upper surface of the main lifting mechanism B2 is connected to the lower surface of the horizontal beam B12. The two vertical beams B13 are each provided with a groove B131. The two ends of the upper pressing plate B3 are respectively slidably set in the corresponding grooves B131. In this embodiment, the upper surface of the inverted L-shaped bracket B11 is connected to the sheet metal cutting and welding device G. Both the front auxiliary dosing device B and the rear auxiliary dosing device D have two main lifting mechanisms B2, one on each side of the crossbeam B12, to enhance the smooth movement of the upper platen B3. When the main lifting mechanism B2 rises, it moves the upper platen B3 within the groove B131, causing it to rise. When the main lifting mechanism B2 descends, it moves the upper platen B3 within the groove B131, causing it to descend. This arrangement ensures smoother movement of the upper platen B3 and enhances the rigidity of the auxiliary dosing frame B1.

[0084] See also Figure 13Furthermore, the main lifting mechanism B2 is an oil cylinder, and an auxiliary lifting mechanism B5 is also provided on the beam B12. The auxiliary lifting mechanism B5 is a cylinder, and the output end of the cylinder is set downward and connected to the upper surface of the upper pressure plate B3; the upper surface of the beam B12 is also provided with an emergency manual air valve B51, and the emergency manual air valve B51 is connected to the auxiliary lifting mechanism B5 through a pipeline (not shown in the figure). In actual use, when the cylinder is running, no gas is introduced into the cylinder, so that the output end of the cylinder can rise as the cylinder output end rises, and fall as the cylinder output end falls; when the cylinder fails, after the hydraulic oil in the cylinder is unloaded, due to the action of gravity, the output end of the cylinder will naturally move downward, thereby pressing the upper pressure plate B3 down to the lower pressure plate B4. At this time, by opening the emergency manual air valve B51, the gas in the workshop is connected to the cylinder through the pipeline, and the upper pressure plate B3 is driven to rise through the contraction of the cylinder output end, thereby releasing the clamping force on the sheet material, thereby not affecting the passage of the sheet material.

[0085] See also Figure 13 、 Figure 14 Furthermore, a screw seat B6 is provided on the crossbeam B12. The screw of the screw seat B6 passes through the crossbeam B12 and is fixed to the crossbeam B12 via a nut. The lower portion of the screw seat B6 is connected to the auxiliary lifting mechanism B5. With this arrangement, the position of the lower pressure plate B4 can be adjusted by adjusting the relative position of the screw on the screw seat B6 and the crossbeam B12.

[0086] See also Figure 13 Furthermore, the front side walls of the two inverted L-shaped brackets B11 are connected to the same first oil pipe B22 and second oil pipe B23. Second valves B24 are provided at both ends of the first oil pipe B22 and the second oil pipe B23. The first oil pipe B22 and the second oil pipe B23 are connected to the main lifting mechanism B2 via pipelines (not shown). In actual use, the first oil pipe B22 is connected to the oil inlet of the oil cylinder, and the second oil pipe B23 is connected to the oil outlet of the oil cylinder. When the oil cylinder malfunctions, the hydraulic oil at the oil inlet and outlet of the oil cylinder can be discharged by opening the second valve B24, facilitating maintenance of the oil cylinder. At the same time, the provision of the auxiliary lifting mechanism B5 does not affect the passage of sheet metal, meaning there is no need to shut down the main lifting mechanism B2 for maintenance.

[0087] See also Figure 13 Furthermore, an upper platen connection base B21 is provided at the output end of the main lifting mechanism B2, and the upper platen B3 extends through both sides of the upper platen connection base B21. This arrangement improves the connectivity between the upper platen B3 and the main lifting mechanism B2, thereby ensuring smooth movement of the upper platen B3.

[0088] See also Figure 13 Furthermore, a support plate B7 is provided on the front side wall of the front auxiliary material setting device B. The upper surface of the support plate B7 is flush with the upper surface of the lower pressing plate B4. The support plate B7 is provided to support the front sheet material conveyed from the front and the rear sheet material conveyed from the rear, so that they can enter the gap between the upper pressing plate B3 and the lower pressing plate B4 horizontally.

[0089] See also Figure 13 Furthermore, a front anti-stuck plate B8 is provided on the front side wall of the inverted L-shaped bracket B11. The front anti-stuck plate B8 is arranged to tilt downward from the front to the back. This arrangement can guide upward-curving sheet materials, preventing them from directly contacting the front side wall of the upper platen B3 due to upward curvature, thereby preventing them from entering the gap between the upper platen B3 and the lower platen B4.

[0090] See also Figure 14 、 Figure 15 Furthermore, a rear anti-stuck plate B9 is installed on the rear sidewall of the inverted L-shaped bracket B11. This plate B9 is tilted downward from front to back, with the horizontal extension of its highest point higher than the horizontal extension of the lowest point of the front anti-stuck plate B8. Similarly, the provision of rear anti-stuck plate B9 allows the sheet metal to smoothly pass through the gap between the upper platen B3 and the lower platen B4.

[0091] See also Figure 13 Furthermore, hoisting arms B111 are provided on the outer side walls of the two inverted L-shaped brackets B11. The front auxiliary material-sizing device B, rear auxiliary material-sizing device D, front sheet metal automatic positioning device E, and rear sheet metal automatic positioning device F are all modular structures. The hoisting arms B111 are used to hoist the front auxiliary material-sizing device B and rear auxiliary material-sizing device D using a crane and then install them with the other modular structures, improving installation efficiency.

[0092] See also Figure 16 Furthermore, the sheet metal cutting and welding device G includes a work frame G1, a slide G2 arranged on the work frame G1, an X-axis driving assembly G3 that drives the slide G2 to move forward and backward, a Y-axis driving assembly G4 that drives the slide G2 to move left and right, a mounting arm G5 connected to the slide G2, a cutting assembly G7 arranged on the side wall of the mounting arm G5 and a Z-axis cutting driving assembly G6 that drives the cutting assembly G7 to move up and down, a welding assembly G9 arranged on the other side wall of the mounting arm G5 and a Z-axis welding driving assembly G8 that drives the welding assembly G9 to move up and down.

[0093] When the sheet metal cutting and welding device G is in standby mode, the slide G2 is located at the end positions on both sides. When cutting the front and rear sheets, the X-axis drive assembly G3 drives the mounting arm G5 to move along the front-to-back direction of the work frame G1 so that the welding assembly G9 reaches the top of the rear sheet metal. Then the Z-axis cutting drive assembly G6 drives the cutting assembly G7 to move downward, and the Y-axis drive assembly G4 drives the slide G2 to move horizontally to the left or right from the end of the work frame G1. During the translation process, the cutting assembly G7 cuts off the edge of the head of the rear sheet metal, and then the cutting assembly G7 is reset to the end position; then the front sheet metal is transported from the front to the front sheet metal automatic After the front sheet is clamped by the automatic positioning device E on the positioning device E, the mounting plate F61 similarly moves forward and backward, followed by the cutting assembly G7 moving downward. The slide G2 then shifts leftward or rightward from the end. The cutting assembly G7 cuts off the edge of the rear end of the front sheet, and the slide G2 returns to the other end. The front feeder C1 and the rear feeder C3 then approach each other, bringing the rear end of the front sheet into contact with the head of the rear sheet, triggering the welding assembly G9 to shift leftward or rightward from the other end to weld the sheets. When the front and rear sheets are stacked and welded, to improve welding quality, the welding assembly G9 must move back and forth along the workbench G1 once, first from one end to the other, and then from the other end to the other. The sheet cutting and welding device G allows the cutting assembly G7 and the welding assembly G9 to share a set of X-axis drive assemblies G3 and Y-axis drive assemblies G4, achieving both sheet cutting and welding, thereby reducing the volume of the combined laser cutting and welding machine.

[0094] See also Figure 17 、 Figure 18 Furthermore, the X-axis drive assembly G3 includes an X-axis drive motor G31, an X-axis driving wheel G32, an X-axis driven wheel G33, an X-axis synchronous belt G34, an X-axis screw G35, an X-axis nut seat G36 and an X-axis bearing seat G37; the X-axis drive motor G31 is arranged on the upper surface of the slide G2, the output end of the X-axis drive motor G31 is transmission-connected to the X-axis driving wheel G32, and the X-axis driven wheel G33 is arranged on the upper surface of the slide G2 Below, the X-axis synchronous belt G34 is wound around the X-axis driving wheel G32 and the X-axis driven wheel G33; both ends of the X-axis screw G35 are respectively connected to the X-axis bearing seat G37, and the X-axis bearing seat G37 located in front of the X-axis driven wheel G33 is connected to the X-axis driven wheel G33; the X-axis screw G35 is connected to the X-axis nut seat G36, and the lower surface of the X-axis nut seat G36 is connected to the upper surface of the mounting arm G5.

[0095] In actual use, the X-axis drive motor G31 rotates, driving the X-axis driving pulley G32, X-axis synchronous belt G34, and X-axis driven pulley G33, providing driving force for the rotation of the X-axis lead screw G35. This in turn causes the X-axis nut holder G36, which is connected to the X-axis lead screw G35, to move on the X-axis lead screw G35, driving the cutting assembly G7 and welding assembly G9 on the mounting arm G5 to move simultaneously. When the X-axis drive motor G31 rotates in the opposite direction, it drives the cutting assembly G7 and welding assembly G9 on the mounting arm G5 in opposite directions. This structure has high precision and transmission efficiency, allowing the cutting assembly G7 or welding assembly G9 to accurately reach above the front or rear sheet metal.

[0096] See also Figure 18 Furthermore, an X-axis guide rail G38 is provided on the lower surface of the slide G2, on which an X-axis slider G39 slides. The lower surface of the X-axis slider G39 is connected to the upper surface of the X-axis nut seat G36. This arrangement improves the smooth movement of the X-axis nut seat G36, thereby improving the stability of the cutting assembly G7 and welding assembly G9 on the mounting arm G5.

[0097] See also Figure 18 Furthermore, an anti-collision rubber G40 is provided in front of the X-axis bearing seat G37. The anti-collision rubber G40 is provided to prevent any component in the X-axis drive assembly G3 from directly colliding with the X-axis bearing seat G37 when a component fails.

[0098] See also Figure 17 Furthermore, an X-axis drive motor adjustment seat G11 is provided on the upper surface of the slide G2, and a plurality of first mounting holes C612 are provided on the X-axis drive motor adjustment seat G11 along its height direction, and an X-axis motor mounting plate G12 is provided on the side wall of the X-axis drive motor adjustment seat G11, and a plurality of first waist-shaped holes are provided on the X-axis motor mounting plate G12 along its height direction, and the first waist-shaped holes are connected to the corresponding first mounting holes C612 through connecting parts; the X-axis drive motor G31 is installed on the X-axis motor mounting plate G12.

[0099] In actual use, the position of the X-axis motor mounting plate G12 on the adjustment base G11 of the X-axis drive motor G31 can be adjusted according to the tightness of the X-axis synchronous belt G34 to adjust the tension of the X-axis synchronous belt G34. Specifically, when the X-axis synchronous belt G34 is loose, loosen the connector, move the X-axis motor mounting plate G12 upward, and then pass the connector through the first waist-shaped hole and the first mounting hole C612 to secure the X-axis motor mounting plate G12 to the adjustment base G11 of the X-axis drive motor G31. When the X-axis synchronous belt G34 is tight, loosen the connector, move the X-axis motor mounting plate G12 downward, and then tighten the connector. In this embodiment, the connector can be configured as a screw and a nut threadedly connected to the screw.

[0100] See also Figure 19 Furthermore, the Y-axis drive assembly G4 includes a Y-axis drive motor G41, a Y-axis first driving wheel G42, a Y-axis second driving wheel G43, a Y-axis first synchronous belt G44, a Y-axis driving shaft G45, a Y-axis first driven wheel G46, a Y-axis second driven wheel G47, a Y-axis driven shaft G48 and a Y-axis second synchronous belt G49; the Y-axis driving shaft G45 and the Y-axis driven shaft G48 are respectively arranged on both sides of the workbench G1, and the output end of the Y-axis drive motor G41 is transmission-connected to the Y-axis first driving wheel G42, and the Y-axis second driving wheel G43 It is arranged on the Y-axis driving shaft G45, and the Y-axis first synchronous belt G44 is wound between the Y-axis first driving wheel G42 and the Y-axis second driving wheel G43. The two ends of the Y-axis driving shaft G45 are respectively connected to the Y-axis first driven wheel G46; the two ends of the Y-axis driven shaft G48 are respectively connected to the Y-axis second driven wheel G47, and the Y-axis second synchronous belt G49 is wound between the Y-axis first driven wheel G46 and the Y-axis second driven wheel G47 located on the same side; the slide G2 is arranged across the two Y-axis second synchronous belts G49.

[0101] In actual use, the Y-axis drive motor G41 rotates, sequentially driving the Y-axis first driving pulley G42, the Y-axis first synchronous belt G44, and the Y-axis second driving pulley G43. This then drives the Y-axis driving shaft G45, which in turn drives the Y-axis first driven pulley G46 connected to both ends of the Y-axis driving shaft G45. The Y-axis first driven pulley G46 then drives the Y-axis second synchronous belt G49, the Y-axis second driven pulley G47, and the Y-axis driven shaft G48, thereby moving the slide G2. When the Y-axis drive motor G41 rotates in the reverse direction, it drives the slide G2 in the reverse direction. This structure has a high load-bearing capacity and can ensure the smooth movement of the slide G2.

[0102] See also Figure 17Furthermore, the work frame G1 is also provided with a Y-axis guide rail G13, on which a Y-axis slider G14 is slidably provided. A Y-bearing support plate G15 is provided on the upper surface of the Y-axis slider G14, and the Y-axis second synchronous belt G49 is provided on the upper surface of the Y-bearing support plate G15. Since the Y-axis second synchronous belt G49 is long and the slide G2 is heavy, the Y-bearing support plate G15 is provided to support the slide G2 and prevent the Y-axis second synchronous belt G49 from falling. Similarly, the provision of the Y-axis guide rail G13 and the Y-axis slider G14 provides a guiding function for the movement of the slide G2, thereby enhancing the smooth movement of the slide G2.

[0103] See also Figure 19 Furthermore, the work frame G1 is also provided with a Y-axis drive motor adjustment seat G16, which is provided with a second waist-shaped hole along its height. A Y-axis motor mounting plate G17 is provided on the sidewall of the Y-axis drive motor adjustment seat G16.

Similarly, through the above arrangement, the tightness (i.e., tension) of the Y-axis first synchronous belt G44 can be adjusted. The specific operation steps are basically the same as those for the X-axis drive motor G31 adjustment seat G11 and will not be repeated here.

A sensing rod G21 is provided on the lower surface of the slide G2, and the in-position sensor group G18 is used to sense the sensing rod G21. The in-position sensor group G18 is electrically connected to the control mechanism. During actual use, when the sensing rod G21 on the slide G2 moves onto the first limit sensor G181, the first limit sensor G181 transmits a signal to the control mechanism, which in turn controls the Y-axis drive motor G41 to stop or reverse rotation. When the sensing rod G21 on the slide G2 moves onto the second zero-position sensor G182, the second zero-position sensor G182 transmits a signal to the control mechanism, which in turn controls the Y-axis drive motor G41 to stop or reverse rotation. The provision of the second limit sensor G183 prevents the Y-axis drive motor G41 from continuing to operate if the second zero-position sensor G182 fails, potentially causing the slide G2 to collide with the workbench G1. This configuration enhances the precision of the slide G2's movement and improves the interoperability of the sheet metal cutting and welding device G.

A Z-axis cutting slider G67 slides on the Z-axis cutting guide rail G66. The sidewall of the Z-axis cutting slider G67 is connected to the sidewall of the Z-axis cutting nut seat G64. This arrangement improves the smooth movement of the Z-axis cutting nut seat G64, thereby reducing vibration of the cutting assembly G7 and improving cutting quality.
