Description

Technical Field

[0001] This invention relates to the field of laser cutting machine equipment technology, and in particular to a split-type cutting machine. Background Technology

[0002] Laser cutting machines have advantages such as high cutting precision, small kerf, good cutting quality, and no limitation on cutting patterns. As a result, they have replaced traditional metal cutting equipment and are widely used in metal processing industries.

[0003] Most existing laser cutting machines use a welded, one-piece construction for the machine bed, making it impossible to disassemble. Therefore, for transportation, only crates suitable for extra-long, extra-wide, and extra-height machines can be used. This method is more expensive than container shipping and requires additional wooden crates, further increasing logistics costs. However, a small number of laser cutting machines feature a split-type machine bed design, with two independent sides assembled via multiple connecting beams. While this allows for disassembly and transport, the low alignment precision of the two sides results in low structural stability, affecting cutting accuracy. Furthermore, the time-consuming assembly process increases labor costs.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a split-type cutting machine, which aims to save logistics costs by disassembling the bed and loading it into a container for transportation, as well as to make the bed assembly convenient and structurally stable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A split-type cutting machine includes a split-structure bed, a first worktable mounted on the bed, a laser mounted above the bed, and a three-axis moving mechanism for driving the laser. The bed includes an integral main frame, side beams, and connecting beams. The front ends of the main frame are provided with first connecting plates on both sides, and the rear ends of the two side beams are provided with second connecting plates. The first and second connecting plates are connected by a plurality of positioning pin assemblies and a first connecting assembly. The two ends of the connecting beams are spliced ​​to the front ends of the two side beams, respectively. The main frame is provided with a first heat insulation assembly arranged parallel to the connecting beams. The bottom of the main frame is provided with a first height adjustment foot, and the bottom of the side beams is provided with a second height adjustment foot. The bottom of the connecting beams is provided with a third height adjustment foot.

[0008] The positioning pin assembly includes a pin, a positioning washer, a removal seat, and a positioning screw. The removal seat is located on the first connecting plate. The first connecting plate and the second connecting plate are respectively provided with a communicating positioning hole. The pin is located in the positioning hole. The positioning screw can pass through the positioning washer and be threadedly connected to the pin, or it can pass through the removal seat and be threadedly connected to the pin.

[0009] It also includes adjustment seats, several of which are respectively located on both sides of the side beam. Adjustment screws are threaded onto the adjustment seats, and the ends of the adjustment screws abut against the side walls of the side beam.

[0010] A connecting seat is provided between the side beam and the connecting beam. The connecting seat has an L-shaped structure. One side of the connecting seat has several horizontally arranged first waist holes, and the other side of the connecting seat has several vertically arranged second waist holes.

[0011] The first heat insulation component includes a door-shaped cover, a fourth height adjustment foot located at the bottom of the door-shaped cover, and two first heat-resistant layers symmetrically located at the top of the door-shaped cover, with the first heat-resistant layers inclined downwards.

[0012] It also includes several second heat insulation components located between the main frame and the connecting beam. The second heat insulation components include a guide beam, a fifth height adjustment foot located at the bottom of the guide beam, and two second heat-resistant layers symmetrically located at the top of the guide beam. The second heat-resistant layers are inclined downwards.

[0013] The first workbench includes a platform frame and a rack. Side support plates are provided on the left and right sides of the platform frame. The side support plates are provided with slots arranged at equal intervals. Multiple racks are correspondingly arranged on the slots. The side support plates are provided with pressure plates that press the ends of the racks. The platform frame is provided with several racks perpendicular to the racks and several reinforcing beams parallel to the racks. The racks are provided with slots that match the racks. The upper surface of the reinforcing beams is provided with a third heat-resistant layer.

[0014] It also includes a second worktable and an exchange drive device. The first and second worktables are slidably connected to the bed, and the exchange drive device drives the first and second worktables to perform alternating translational movements. The bed also includes a base frame spliced ​​to the rear end of the main frame. The base frame includes two rear beams spliced ​​to the rear ends of the main frame and several crossbars located between the two rear beams. Several sixth height adjustment feet are provided at the bottom of the rear beams.

[0015] Several rollers are rotatably connected to the bottom of the first workbench and the bottom of the second workbench. Each side beam is equipped with two tracks that are slidably connected to the two rows of rollers, and both tracks extend to the rear beam.

[0016] The connecting beam is provided with symmetrically arranged anti-collision seats and a clamping device between the two anti-collision seats. The clamping device includes a lifting mechanism, a follower seat at the output end of the lifting mechanism, a first tension hook at the front end of the first workbench and a second tension hook at the front end of the second workbench. The follower seat is provided with a first locking wheel that can be engaged with the first tension hook and a second locking wheel that can be engaged with the second tension hook.

[0017] Beneficial effects:

[0018] The split-type cutting machine provided by this invention features a bed constructed from a single main frame, two side beams, and connecting beams. Using the first and second connecting plates as reference surfaces, and with the aid of positioning pin assemblies, the two side beams can be quickly joined to the main frame. This results in high assembly precision and structural stability of the bed, facilitating the assembly of various components. Furthermore, after disassembly, the single-frame main structure, side beams, connecting beams, and the first worktable can be directly loaded into a container, facilitating transportation and saving logistics costs.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the invention, the X-axis direction is the same as the front-back direction, the Y-axis direction is the same as the left-right direction, and the Z-axis direction is the same as the up-down direction; the direction of the main frame 11 toward the side beam 12 is "front", and "front" is opposite to "back".

[0041] Please see Figure 1-19 This invention provides a split-type cutting machine, including a split-structure bed 1, a first worktable 2 mounted on the bed 1, a laser 3 mounted above the bed 1, and a three-axis moving mechanism 4 for driving the laser 3. The bed 1 includes an integral main frame 11, side beams 12, and connecting beams 13. The front ends of the main frame 11 are respectively provided with first connecting plates 111, and the rear ends of the two side beams 12 are respectively provided with second connecting plates 121. The first connecting plates 111 and the second connecting plates 121 are connected by a plurality of positioning pin assemblies 14 and a first connecting assembly 15. The two ends of the connecting beams 13 are respectively spliced ​​to the front ends of the two side beams 12. The main frame 11 is provided with a first heat insulation assembly 16 arranged parallel to the connecting beams 13. The bottom of the main frame 11 is provided with a first height adjustment foot 112; the bottom of the side beams 12 is provided with a second height adjustment foot 122; and the bottom of the connecting beams 13 is provided with a third height adjustment foot 131.

[0042] In the assembly of the bed 1, the corresponding surfaces of the first connecting plate 111 and the second connecting plate 121 serve as reference surfaces. The second connecting plate 121 and the first connecting plate 111 are spliced ​​together, and with the help of the positioning pin assembly 14, the two side beams 12 can be quickly spliced ​​onto the front end of the main frame 11, resulting in high docking accuracy. Since the main frame 11 is a one-piece welded structure, and the front end of the main frame 11 is spliced ​​with the two side beams 12, and the front ends of the two side beams 12 are spliced ​​with the two ends of the connecting beam 13, the bed 1 has high structural stability. After the bed 1 is assembled, subsequent components such as the first worktable 2, outer casing, laser 3, dust extraction fan, water pump, and voltage stabilizer can be assembled to form a complete laser cutting machine.

[0043] The outer casing is assembled from various sheet metal blocks and is used to surround the laser cutting machine, thus protecting the operator's body during the laser cutting process. In this embodiment, during transportation, the outer casing is disassembled into a main bed module 91, a front sheet metal module 92, and a middle sheet metal module 93. The main bed module 91 is mounted on the main frame 11 and is not separated from the main frame 11 during cabinet loading. The front sheet metal module 92 is located on the front end of the two side beams 12. The middle sheet metal module 93 is used to connect the main bed module 91 and the front sheet metal module 92. By modularly disassembling the outer casing, the assembly time of the outer casing can be saved.

[0044] See Figure 18 , 19The split-type cutting machine provided by this invention can be disassembled and installed in two containers. The dust extraction fan, laser 3, front sheet metal module 92, main bed module 91 and main frame 11 are placed in one container. Here, the length of the main bed module 91 and the length of the front sheet metal module 92 are both less than the width of the container so that the main bed module 91 and the front sheet metal module 92 can be placed in the container, and the main frame 11 is fixed in the main bed module 91, which can reduce the space occupied. The water pump, voltage stabilizer, intermediate sheet metal module 93, first worktable 2, side beam 12, connecting beam 13, etc. can be placed in another container. Here, the first worktable 2 is placed along the diagonal direction of the container to achieve the purpose of making reasonable use of the container space.

[0045] It should be noted that the length of the main frame 11 in the X-axis direction should be less than the width of the container to avoid the main frame 11 being too wide in the Y-axis direction and thus unable to be loaded into the container.

[0046] Preferably, during disassembly, the three-axis moving mechanism 4 can be moved onto the main frame 11 and loaded into the container along with the main frame 11 to reduce subsequent assembly processes. The three-axis moving mechanism 4 is existing technology, used to move the laser 3 along the X, Y, and Z axes. It includes first guide rails on the left and right sides of the bed 1, a gantry moving along the first guide rails, an X-axis drive assembly driving the gantry, a second guide rail on the top of the gantry, a slide moving along the second guide rail, a Y-axis drive assembly driving the slide, and a Z-axis lifting assembly on one side of the slide. The laser 3 is located at the output end of the Z-axis lifting assembly. Under the action of the X-axis drive assembly, the gantry moves horizontally along the first guide rail; under the action of the Y-axis drive assembly, the slide moves horizontally along the second guide rail; and under the action of the Z-axis lifting assembly, the laser 3 moves up and down, enabling the laser 3 to cut the workpiece according to processing requirements. The first guide rail is a segmented guide rail. When disassembling the bed 1, only the section of the first guide rail that connects the main frame 11 and the side beam 12 needs to be disassembled, thus saving subsequent assembly time.

[0047] In this embodiment, the preferred option is described in the reference section. Figure 7 The main frame 11 includes two symmetrically arranged main beams 113. A bottom beam 114 is welded and fixed to the front end of the two main beams 113, and a cross beam 115 is welded and fixed to the middle of the two main beams 113. The bottom beam 114 and the cross beam 115 are parallel to each other, and the first heat insulation component 16 is located on the bottom beam 114. The two main beams 113, the bottom beam 114, and the cross beam 115 are spliced ​​into a frame structure, which makes the main frame 11 structurally stable and provides a basis for the assembly stability of the bed 1. Moreover, the main frame 11 with an integrated structure, the side beams 12, and the connecting beams 13 are combined to form a split bed 1, which is easy to load into a container after disassembly, resulting in low logistics costs.

[0048] To ensure the alignment accuracy between the main frame 11 and the side beam 12, two first connecting components 15 are provided on the side of the first connecting plate 111 and the second connecting plate 121 closest to the inner side of the main frame 11; three first connecting components 15 and two positioning pin components 14 are provided on the side of the first connecting plate 111 and the second connecting plate 121 furthest from the inner side of the main frame 11, with each positioning pin component 14 located between two adjacent connecting components. By providing two positioning pin components 14 between each first connecting plate 111 and the second connecting plate 121, the alignment accuracy during splicing can be improved, and by providing five connecting components, the stability of the connection can be improved.

[0049] Further, see Figure 8 , 9 The positioning pin assembly 14 includes a pin 141, a positioning washer 142, a take-out seat 143, and a positioning screw 144. The take-out seat 143 is disposed on the first connecting plate 111. The first connecting plate 111 and the second connecting plate 121 respectively have communicating positioning holes 1111. The pin 141 is disposed in the positioning hole 1111. The positioning screw 144 can pass through the positioning washer 142 and be threadedly connected to the pin 141, or it can pass through the take-out seat 143 and be threadedly connected to the pin 141. Specifically, the pin 141 includes an insertion part 1411 that matches the positioning hole 1111 and an abutment part 1412 located at the end of the insertion part 1411. The insertion part 1411 has a threaded hole 1413 that is threadedly connected to the positioning screw 144. When assembling the main frame 11 and the side beam 12, the first connecting plate 111 and the second connecting plate 121 are aligned. Then, the insertion part 1411 of the pin 141 is inserted into the positioning hole 1111, and the abutment part 1412 fits against the first connecting plate 111. The positioning screw 144 passes through the positioning washer 142 and connects to the threaded hole 1413 of the pin 141 from one side of the second connecting plate 121 to achieve the splicing and positioning of the first connecting plate 111 and the second connecting plate 121. Conversely, when removing the positioning pin assembly 14, the positioning screw 144 is first unscrewed. The positioning screw 144 passes through the removal seat 143 and is screwed into the threaded hole 1413 of the pin 141. Then, the positioning screw 144 is rotated in the opposite direction. Utilizing the threaded connection characteristics between the positioning screw 144 and the pin 141, the pin 141 can be slowly pulled out of the positioning hole 1111.

[0050] Furthermore, see Figure 10The system also includes adjustment seats 17, with several adjustment seats 17 respectively located on both sides of the side beam 12. Adjustment screws 171 are threaded onto each adjustment seat 17, with the ends of the adjustment screws 171 abutting against the side wall of the side beam 12. Preferably, each side beam 12 is provided with four adjustment seats 17, and the four adjustment seats 17 are symmetrically arranged. Each adjustment seat 17 is threaded with two adjustment screws 171. During assembly, the two side beams 12 are placed along the extension directions of the front ends of the main frame 11, and then multiple adjustment seats 17 are correspondingly placed on both sides of the side beam 12. The adjustment seats 17 are fixed to the ground with screws. The position between the ends of the adjustment screws 171 on two symmetrically arranged adjustment seats 17 is the placement position of the side beam 12. Fine-tuning of the installation position of the side beam 12 is achieved by adjusting the screw length of the adjustment screws 171 on each adjustment seat 17, allowing the first connecting plate 111 and the second connecting plate 121 to be quickly assembled, further saving assembly time. After assembly, each adjustment seat 17 needs to be removed to avoid positional interference between the adjustment seat 17 and the second heat insulation component 18.

[0051] In a preferred embodiment, see [reference] Figure 2 , 3 A connecting seat 132 is provided between the side beam 12 and the connecting beam 13. The connecting seat 132 has an L-shaped structure. One side of the connecting seat 132 has several horizontally arranged first waist holes 1321, and the other side of the connecting seat 132 has several vertically arranged second waist holes 1322. The first waist holes 1321 are connected to the front end of the side beam 12 through connectors, and the second waist holes 1322 are connected to the end of the connecting beam 13 through connectors. With the above arrangement, the connecting beam 13 and the side beam 12 can be flexibly spliced ​​together.

[0052] In this embodiment, it is preferable that there are four first height adjustment feet 112 and four second height adjustment feet 122 on each side beam 12. The first height adjustment feet 112, the second height adjustment feet 122 and the third height adjustment feet 131 provide independent support for the main frame 11, the side beam 12 and the connecting beam 13, respectively, so that the installation height of each component can be adjusted separately, so that the connection positions between the components are on the same horizontal plane, which facilitates assembly.

[0053] Specifically, see Figure 2 , 5The first adjustable foot 112 includes a mounting base 1121 at the bottom of the main frame 11 and a first foot plate 1122 below the mounting base 1121. A first adjusting foot cup 1123 and a first adjusting screw 1124 are provided between the mounting base 1121 and the first foot plate 1122. Adjusting nuts are provided on both the first adjusting foot cup 1123 and the first adjusting screw 1124. By rotating the adjusting nuts, the distance between each first foot plate 1122 and the mounting base 1121 can be adjusted, allowing the operator to adjust the levelness of the main frame 11 according to the flatness of the ground. The first foot plate 1122 can be fixed to the ground with expansion bolts to ensure the stability of the main frame 11 installation.

[0054] Similarly, the structures of the second height adjustment foot 122 and the third height adjustment foot 131 are similar to those of the first height adjustment foot 112. For details, refer to the structure of the first height adjustment foot 112. By setting the first height adjustment foot 112, the second height adjustment foot 122 and the third height adjustment foot 131, the installation height of the main frame 11, the side beam 12 and the connecting beam 13 can be adjusted according to the flatness of the ground and the assembly requirements, which facilitates the operator to assemble the bed 1. The first height adjustment foot 112, the second height adjustment foot 122 and the third height adjustment foot 131 can be fixed to the ground with expansion bolts, which can improve the stability of the bed 1 structure after assembly and prevent the bed 1 from shifting due to the impact of heavy plates.

[0055] In a preferred embodiment, see [reference] Figure 2 , 7 11. The first heat insulation component 16 includes a door-shaped cover 161, a fourth height adjustment foot 162 disposed at the bottom of the door-shaped cover 161, and two first heat-resistant layers 163 symmetrically disposed at the top of the door-shaped cover 161, the first heat-resistant layers 163 being inclined downwards. This arrangement protects the connecting beam 13, preventing the laser 3 from prolonged contact with the connecting beam 13 during cutting, thus avoiding heat transfer to the bed 1.

[0056] Further, see Figure 2 , 7It also includes several second heat insulation components 18 disposed between the main frame 11 and the connecting beam 13. Each second heat insulation component 18 includes a guide beam 181, a fifth height adjustment foot 182 disposed at the bottom of the guide beam 181, and two second heat-resistant layers 183 symmetrically disposed at the top of the guide beam 181. The second heat-resistant layers 183 are inclined downwards. Both the first heat insulation component 16 and the second heat insulation component 18 guide the material cart's pushing and pushing direction. The material cart is disposed on both sides of the first heat insulation component 16 and the second heat insulation component 18, and is used to collect waste generated during the cutting process. The first heat-resistant layer 163 and the second heat-resistant layer 183 guide the waste falling from above into the material carts on both sides, preventing waste from accumulating on the top of the gate cover 161 and the guide beam 181.

[0057] It should be noted that the material cart, used to collect dust and waste generated during laser cutting, is not shown in the attached drawing. The material cart represents existing technology, and its specific structure and working principle will not be elaborated further.

[0058] Specifically, see Figure 11 The fourth height adjustment foot 162 includes a second foot plate 1621 located below the portal cover 161 and a second height adjustment screw 1622 located between the portal cover 161 and the second foot plate 1621. An adjusting nut is provided on the second height adjustment screw 1622. By rotating the adjusting nut, the installation height of the portal cover 161 is adjusted, ensuring that the side wall of the portal cover 161 guides the material cart, and that the inclined end of the first heat-resistant layer 163 is positioned above the material cart. The second foot plate 1621 can be fixed to the ground with expansion bolts to ensure the stability of the first heat insulation component 16 installation and prevent positional displacement due to collisions with the material cart.

[0059] Similarly, the structure of the fifth height adjustment foot 182 is similar to that of the fourth height adjustment foot 162. For details, please refer to the structure of the fourth height adjustment foot 162, which will not be repeated here.

[0060] In a preferred embodiment, see [reference] Figure 12 , 1314. The first workbench 2 includes a platform frame 21 and racks 22. Side support plates 23 are provided on the left and right sides of the platform frame 21, and slots 231 are arranged at equal intervals on the side support plates 23. Multiple racks 22 are correspondingly arranged in the slots 231. Pressure plates 24 are provided on the side support plates 23 to press the ends of the racks 22. Under the action of the pressure plates 24, multiple racks 22 can be fixed to ensure that the workbench can tilt inside the container after loading. Removing the pressure plates 24 facilitates the replacement of the racks 22. The platform frame 21 contains several clamping strips 25 perpendicular to the racks 22 and several reinforcing beams 26 parallel to the racks 22. The clamping strips 25 have slots 251 that match the racks 22. The clamping strips 25 support the racks 22 to ensure that the racks 22 can support the workpiece to be cut, and the reinforcing beams 26 enhance the structural strength of the workbench. The upper surface of the reinforcing beam 26 is provided with a third heat-resistant layer 27, which protects the reinforcing beam 26 and prevents it from deforming due to heat during laser cutting, thereby affecting the service life of the worktable.

[0061] Optionally, the first heat-resistant layer 163, the second heat-resistant layer 183, and the third heat-resistant layer 27 are made of refractory bricks, which serve as fire-resistant and heat-insulating materials.

[0062] To improve cutting efficiency, please refer to Figure 1 The system also includes a second worktable 5 and an exchange drive device 6. The first worktable 2 and the second worktable 5 are slidably connected to the bed 1, and the exchange drive device 6 drives the first worktable 2 and the second worktable 5 to perform alternating translational movements. The bed 1 also includes a base frame 19 spliced ​​to the rear end of the main frame 11. The base frame 19 includes two rear beams 191 spliced ​​to the rear sides of the main frame 11 and several crossbars 192 disposed between the two rear beams 191. Several sixth height adjustment feet 193 are provided at the bottom of the rear beams 191. By setting the base frame 19, when one worktable is cutting, the other worktable is loading and unloading materials on the base frame 19.

[0063] Further, see Figure 4 The main frame 11 has third connecting plates 116 on both sides of its rear end, and a fourth connecting plate 194 on the front end of the rear beam 191. The third connecting plates 116 and the fourth connecting plates 194 are spliced ​​together via a second connecting assembly. During assembly, the corresponding surfaces of the third connecting plates 116 and the fourth connecting plates 194 serve as reference surfaces. The splicing of the third connecting plates 116 and the fourth connecting plates 194 allows the two rear beams 191 to be quickly spliced ​​onto the rear end of the main frame 11. The combination of the two rear beams 191 and multiple crossbars 192 improves the stability of the underframe 19 structure. After disassembly, it can be easily loaded into a container for convenient transportation.

[0064] Optionally, a crossbar 196 connects the top of the main beam 113 and the rear beam 191, further improving the stability of the connection between the base frame 19 and the main frame 11.

[0065] Optional, see below Figure 6 The sixth height adjustment foot 193 includes a foot 1931 located at the bottom of the rear beam 191 and two second adjustment cups 1932 located at the bottom of the foot 1931. The second adjustment cups 1932 are provided with adjustment nuts. By rotating the adjustment nuts, the installation height and levelness of the rear beam 191 can be adjusted individually, which facilitates the splicing of the rear beam 191 with the main frame 1.

[0066] It should be noted that both the first connecting component 15 and the second connecting component include bolts, washers, and nuts, which are commonly used connecting parts between components.

[0067] To achieve a sliding connection between the first worktable 2 and the second worktable 5 and the bed 1, and to facilitate easy disassembly or assembly from or onto the bed 1, refer to... Figure 4 , 12 The bottom of the first workbench 2 and the bottom of the second workbench 5 are rotatably connected to several rollers 28. Each side beam 12 is provided with two tracks 123 that are slidably connected to the two rows of rollers 28, and both tracks 123 extend to the rear beam 191. With the above arrangement, the exchange drive device 6 can synchronously drive the first workbench 2 and the second workbench 5 to move alternately horizontally along the two tracks.

[0068] It should be noted that by adding a second workbench 5, the first workbench 2 and the second workbench 5 can be stacked and placed diagonally on opposite sides of the container when loading it into the container; and the rear beam 191 and the crossbeam 115 can be stacked next to the first workbench 2 along with the side beam 12.

[0069] Further, see Figure 2 The exchange drive device 6 includes a drive shaft 61 rotatably connected to the rear end of the main frame 11, a drive motor 62 driving the drive shaft 61 to rotate, and two chain drive assemblies 63 respectively disposed on both sides of the bed 1. The drive motor 62 drives one of its chain drive assemblies 63 to rotate in both directions, and realizes the synchronous rotation of the two chain drive assemblies 63 through the drive shaft 61, thereby realizing the alternating translational movement of the first worktable 2 and the second worktable 5; specifically, the driving wheel of the chain drive assembly 63 is rotatably connected to the rear end of the main frame 11, its driven wheel is rotatably connected to the front end of the side beam 12, and its chain is sleeved on the driving wheel and the driven wheel. The first worktable 2 is connected to the partial chain located above and close to the driven wheel, and the second worktable 5 is connected to the partial chain located below and close to the driving wheel.

[0070] In a preferred embodiment, see [reference] Figure 1 , 1517. The connecting beam 13 is provided with symmetrically arranged anti-collision seats 7 and a clamping device 8 between the two anti-collision seats 7. The anti-collision seats 7 limit the position of the first worktable 2 or the second worktable 5. The clamping device 8 can clamp the first worktable 2 or the second worktable 5 to prevent the worktable from vibrating during cutting, thereby affecting the cutting accuracy. The clamping device 8 includes a lifting mechanism 81, a follower seat 82 located at the output end of the lifting mechanism 81, a first tension hook 29 located at the front end of the first worktable 2, and a second tension hook 51 located at the front end of the second worktable 5. The follower seat 82 is provided with a first locking wheel 83 that can be engaged with the first tension hook 29 and a second locking wheel 84 that can be engaged with the second tension hook 51. When the first worktable 2 or the second worktable 5 moves to the connecting beam 13, the lifting mechanism 81 drives the follower seat 82 to descend, so that the first locking wheel 83 engages with the first tension hook 29 or the second locking wheel 84 engages with the second tension hook 51, thereby locking the first worktable 2 or the second worktable 5.

[0071] Furthermore, the lifting mechanism 81 includes a support 811 and a drive cylinder 812 vertically mounted on the support 811. The follower seat 82 includes a vertical plate 821 and a horizontal plate 822 spliced ​​into a T-shape. A first chuck 83 is located on the upper part of the vertical plate 821, and a second chuck 84 is located on the lower part of the vertical plate 821. The end of the extension rod of the drive cylinder 812 is connected to the horizontal plate 822. With the above configuration, the extension rod of the drive cylinder 812 extends or retracts, driving the first chuck 83 and the second chuck 84 to perform synchronous lifting and lowering movements. This achieves the use of one drive cylinder 812 to lock the position of the first worktable 2 and the second worktable 5. Compared with the method of using two cylinders for positioning, this saves the use of one cylinder and the air circuit and electrical components connected to the cylinder.

[0072] Optionally, the vertical plate 821 has a vertically extending groove 8211, and the support 811 is provided with a guide plate 823 that is slidably connected to the groove 8211. The guide plate 823 serves to limit the vertical movement of the follower seat 82 and prevent the follower seat 82 from swaying left and right during the lifting process.

[0073] In this embodiment, the guide plate 823 is provided with a mounting plate 824, and a pressure roller 825 is rotatably connected to the mounting plate 824. The wheel surface of the pressure roller 825 acts on the side of the vertical plate 821 away from the first chuck 83. Through the above arrangement, the vertical plate 821 is prevented from tilting to one side after being pressed.

[0074] To ensure that the first pressure roller 825 can press the first tension hook 29 and the second pressure roller 825 can press the second tension hook 51, refer to Figure 15 , 16The first tensioning hook 29 includes a first hook seat 291, on which a first V-groove 292 is formed. A first inclined plate 293 is provided on the side of the first V-groove 292 away from the first worktable 2. The first inclined plate 293 increases the contact area between the first V-groove 292 and the first retaining wheel 83 to ensure that the first retaining wheel 83 can press the first tensioning hook 29. Similarly, the second tensioning hook 51 includes a second hook seat 511, on which a second V-groove 512 is formed. A second inclined plate 513 is provided on the side of the second V-groove 512 away from the second worktable 5. The second inclined plate 513 increases the contact area between the second V-groove 512 and the second retaining wheel 84 to ensure that the second retaining wheel 84 can press the second tensioning hook 51.

[0075] Optionally, the first roller 83 and the second roller 84 can be cam bearing followers, which facilitate downward sliding along the surfaces of the first inclined plate 293 and the second inclined plate 513 to press the first tension hook 29 and the second tension hook 51.

[0076] Further, see Figure 17 Each anti-collision seat 7 is equipped with a first impact block 71 corresponding to the position of the first worktable 2 and a second impact block 72 corresponding to the position of the second worktable 5. The first impact block 71 and the second impact block 72 are used to limit the stop position of the first worktable 2 and the second worktable 5, respectively, to prevent the first worktable 2 or the second worktable 5 from moving beyond its range. One anti-collision seat 7 is equipped with a first limit switch 73 for detecting the position of the first worktable 2 and a second limit switch 74 for detecting the position of the second worktable 5. When the first limit switch 73 detects the first worktable 2, it means that the first worktable 2 has moved to the cutting position; similarly, when the second limit switch 74 detects the second worktable 5, it means that the second worktable 5 has moved to the cutting position. When the above situations occur, the extension rod of the drive cylinder 812 retracts, driving the follower seat 82 to move downward.

[0077] By using the first impact block 71 to limit the position of the first worktable 2 and the first chuck 83 to press down on the first inclined plate 293, the horizontal and vertical movement of the first worktable 2 are limited, resulting in a good clamping effect and high stability of the first worktable 2, effectively preventing vibration of the first worktable 2. Similarly, by using the second impact block 72 to limit the position of the second worktable 5 and the second chuck 84 to press down on the second inclined plate 513, the horizontal and vertical movement of the second worktable 5 are limited, resulting in a good clamping effect and high stability of the second worktable 5, effectively preventing vibration of the second worktable 5.

[0078] It is understood that those skilled in the art can make equivalent substitutions or changes to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
