In actual production and processing, when the side beam inner plate contains multiple regions with varying thickness (such as locally reinforced mounting hole positions), special-shaped cross-section (such as stepped, variable curvature surfaces) or built-in reinforcing rib assemblies, it is difficult to form a single sheet at one time, and it needs to be processed in blocks and then welded, and then the material is fixed with a welding clamp.

[0047] Embodiment 2

[0048] Reference Figures 2 to 10 This embodiment is based on the previous embodiment.

[0049] Specifically, the pressing part 32 comprises a sliding sleeve 32-1 arranged on the outer ring of the sleeve head 31, the outer ring of the sliding sleeve 32-1 is provided with exhaust holes 32-11, one side of the sliding sleeve 32-1 is provided with a fixing sleeve 32-2, one end of the fixing sleeve 32-2 is fixed on the outer ring of the sleeve head 31, a horizontal rod 32-3 is fixed in the fixing sleeve 32-2, the other end of the horizontal rod 32-3 is fixed with a sealing head 32-4, and the sealing head 32-4 is in sliding connection with the sliding sleeve 32-1, the other end of the sealing head 32-4 is fixed with a first spring 32-5, and the other end of the first spring 32-5 is fixed in the sliding sleeve 32-1.

[0050] The exhaust holes 32-11 are a plurality of and circumferentially arranged on the sliding sleeve 32-1, and are obliquely arranged, so that the cleaning range of the jet is expanded during the exhaust operation, so as to ensure the cleanliness of the suction pad 33-2.

[0051] When the sliding sleeve 32-1 is actively displaced, the first spring 32-5 is compressed, and the gas in the sliding sleeve 32-1 can be extruded outward with the assistance of the sealing head 32-4, and finally sprayed out through the exhaust holes 32-11.

[0052] The sleeve 33-1 is fixed with a support 33-10, the receiving sleeve 33-4 is rotationally connected to the support 33-10, the screw sleeve 33-7 is internally threadedly connected with a screw rod 33-9, one end of the screw rod 33-9 is fixed on the threaded head 33-8, and the other end of the screw rod 33-9 is fixed with a hexagonal rod 33-6 and is in sliding connection with the receiving sleeve 33-4.

[0053] Through the arrangement of the bidirectional wind wheel 33-5, the bidirectional wind wheel 33-5 can generate forward rotation or reverse rotation when the gas flows into the sleeve 33-1 or is discharged from the sleeve 33-1, so as to link the receiving sleeve 33-4 to rotate synchronously.

[0054] The hexagonal rod 33-6 is a hexagonal rod, and the receiving sleeve 33-4 is provided with a hexagonal groove matched with the hexagonal rod, so that when the receiving sleeve 33-4 is driven to rotate, the hexagonal rod 33-6 can rotate synchronously.

[0055] One end of the screw sleeve 33-7 is fixed on the support 33-10, and when the screw rod 33-9 generates forward rotation or reverse rotation, the screw rod 33-9 will also move outward or inward under the cooperation of the screw sleeve 33-7.

[0056] When the gas flows through the sleeve 33-1, the bidirectional wind wheel 33-5 rotates automatically, the hexagonal rod 33-6 rotates together with the receiving sleeve 33-4, and under the cooperation of the screw sleeve 33-7, the threaded head 33-8 can rotate forward and move outward when the screw rod 33-9 rotates forward, and the threaded head 33-8 can rotate reversely and move inward when the screw rod 33-9 reverses.

[0057] The locking piece 34 comprises an auxiliary seat 34-1 fixed to the outer circle of the sleeve head 31, a first rotating block 34-2 rotatably connected to the auxiliary seat 34-1, a second rotating block 34-3 rotatably connected to one side of the first rotating block 34-2, a second spring 34-4 fixed to one end of the second rotating block 34-3, a third rotating block 34-5 fixed to the other end of the second spring 34-4, and a fourth rotating block 34-6 rotatably connected to one side of the third rotating block 34-5.

[0058] The fourth rotating block 34-6 is fixed with a locking sleeve 34-61 which is threadedly connected with the threaded head 33-8. A touch switch 34-62 is embedded in the locking sleeve 34-61. The third rotating block 34-5 is slidingly connected in the second rotating block 34-3.

[0059] The first rotating block 34-2 is fixed with an anti-dropping head 34-21. The sleeve 33-1 is provided with a groove 33-11. One end of the sleeve head 31 is fixed with a pressing head 31-1.

[0060] The locking sleeve 34-61 is fixed with a protrusion on the outer circle and is slidingly connected with the groove 33-11, which is used to guide the action of the locking sleeve 34-61, so as to ensure that the locking sleeve 34-61 and the threaded head 33-8 are always in concentric alignment.

[0061] The positioning assembly 4 comprises a sliding rod 41 slidingly connected to the top of the workbench 11, a short rod 42 rotatably connected to the top of the sliding rod 41, an expansion rod 43 rotatably connected to the other end of the short rod 42, a clamping head 44 rotatably connected to the expansion rod 43, a buckle plate 45 rotatably connected to the top of the workbench 11, a positioning frame 46 fixed to the bottom of the workbench 11, a rotating strip 47 rotatably connected to the positioning frame 46, and a pressing seat 48 slidingly connected in the workbench 11.

[0062] The bottom of the sliding rod 41 is in contact with the top of the rotating strip 47. The other end of the rotating strip 47 is in contact with the pressing seat 48.

[0063] The positioning frame 46 divides the rotating strip 47 into a short plate and a long plate. When the sliding rod 41 moves down by a small distance and presses one end of the rotating strip 47 to rotate, the other end of the rotating strip 47 will press the pressing seat 48 to produce a longer displacement.

[0064] The buckle plate 45 is arranged to buckle the sliding rod 41 after the adjustment of the sliding rod 41 is completed, so as to avoid the upward and downward displacement of the sliding rod 41.

[0065] The side of the pressing seat 48 away from the rotating strip 47 is a rubber pad. When the clamping head 44 locks the supporting rod 23, the rubber pad is compressed, which not only prevents the inner plate template 14 from slipping and pressing, but also prevents the inner plate thin material placed on the inner plate template 14 from slipping and pressing, thereby meeting the requirements of pre-pressing and positioning the inner plate template 14 and the inner plate thin material.

[0066] The outer ring of the receiving seat 21 is provided with a clamping hole 21-1 and is in sliding connection with the clamping head 44. The outer ring top of the supporting rod 23 is sleeved with a torsion spring 23-1. One end of the torsion spring 23-1 is fixed to the inner ring of the fixed ring 22, and the other end of the torsion spring 23-1 is fixed to the supporting rod 23.

[0067] Through the arrangement of the torsion spring 23-1, torsion can be provided for the supporting rod 23. Without external force, the supporting rod 23 is prevented from rotating at will, and the initial position of the supporting rod 23 is maintained.

[0068] When the sliding rod 41 is moved downward, the inclination angles of the two expansion rods 43 are adjusted synchronously under the cooperation of the short rod 42, so that the clamping head 44 is moved outward and slides on the clamping hole 21-1, and the supporting rod 23 is tightly pressed to ensure the angle and height of the supporting rod 23.

[0069] The top of the workbench 11 is provided with a displacement slot 11-1. The pressing seat 48 is in sliding connection in the displacement slot 11-1. The third spring 49 is sleeved on the pressing seat 48. One end of the third spring 49 is fixed to the pressing seat 48, and the other end of the third spring 49 is fixed to the inner wall of the displacement slot 11-1.

[0070] When the sliding rod 41 moves downward, one end of the rotating strip 47 is pressed, and the other end of the rotating strip 47 acts on the pressing seat 48. The third spring 49 is stretched, the rubber pad is in contact with the inner plate template 14 or the inner plate thin material and is compressed, and the compression rates of the rubber pad in the two cases are different, but both can play a good antiskid positioning role.

[0071] In use, the inner plate template 14 is placed on the workbench 11 and moved close to the base frame 12. At this time, the sliding rod 41 is driven to move downward, the rotating strip 47 presses the pressing seat 48, the third spring 49 is stretched to pre-press and position the inner plate template 14, and the hands of the operator are released to facilitate the operator to cooperate with the mounting piece 14-1 to fix the inner plate template 14 on the base frame 12. After installation is completed, the sliding rod 41 is loosened, and under the elastic connection of the third spring 49, the pressing seat 48 is reset to drive the sliding rod 41 to move upward and reset.

[0072] The thin material of the edge beam inner plate is placed in contact with the inner plate template 14, and then the supporting rod 23 or the rotating supporting rod 23 is displaced upward and downward to adjust the height or angle of the electric push rod 24. Finally, the above-mentioned sliding rod 41 action steps are repeated to pre-press and position the thin plate by the pressing seat 48, and the supporting rod 23 is locked by the cooperation of the clamping head 44 and the clamping hole 21-1 to ensure the installation stability of the electric push rod 24.

[0073] When the electric push rod 24 is further extended, the first spring 32-5 is compressed, and the gas in the sliding sleeve 32-1 is squeezed out and sprayed through the exhaust hole 32-11 under the cooperation of the sealing head 32-4, thereby cleaning the dust on the part to be adsorbed on the sheet.

[0074] When the electric push rod 24 is further extended, the first spring 32-5 is compressed, and the gas in the sliding sleeve 32-1 is squeezed out and sprayed through the exhaust hole 32-11 under the cooperation of the sealing head 32-4, thereby cleaning the dust on the part to be adsorbed on the sheet.

[0075] During the compression of the suction cup 33-2 and the air bag 33-3, the inclination of the sleeve 33-1 changes according to the shape of the sheet, thereby driving the first rotating block 34-2 to change the inclination, the distance between the second rotating block 34-3 and the third rotating block 34-5 increases or decreases, the second spring 34-4 is stretched or compressed, and the position of the fourth rotating block 34-6 changes.

[0076] When the electric push rod 24 is further extended, the first spring 32-5 is compressed, and the gas in the sliding sleeve 32-1 is squeezed out and sprayed through the exhaust hole 32-11 under the cooperation of the sealing head 32-4, thereby cleaning the dust on the part to be adsorbed on the sheet.

[0077] Similarly, when the electric push rod 24 is retracted, the gas is supplemented into the suction cup 33-2, and the air bag 33-3 is elastically reset, the gas flows into the sleeve 33-1, and under the cooperation of the bidirectional wind wheel 33-5, the threaded head 33-8 is reversed and moved inward to be separated from the locking sleeve 34-61.

[0078] After the positioning and clamping of the sheets on the two inner plate templates 14 are completed, the welding operation can be performed in cooperation with the welding piece 13.

[0079] Embodiment 3

[0080] Reference Figures 4 to 10 This embodiment is based on the previous two embodiments.

[0081] Specifically, the outer circle of the sleeve 33-1 is provided with an anti-falling groove, and the anti-falling groove is in sliding connection with the anti-falling head 34-21, and the anti-falling groove and the anti-falling head 34-21 are both T-shaped in design, which is used to ensure the sliding stability of the sleeve 33-1.

[0082] The mounting piece 14-1 includes a stud fixed to the inner plate template 14, and two hexagonal nuts screwed onto the stud, and the base frame 12 is provided with a wide slot on both sides, which is matched with the hexagonal nut, and a narrow slot is provided in the wide slot, which is matched with the stud. This design can accommodate the mounting piece 14-1 by the base frame 12, so that the two inner plate templates 14 are installed without interference. It should be noted that after the inner plate template 14 is installed, there is still space for the operator to operate between the inner plate template 14 and the base frame 12, which meets the disassembly and assembly operation requirements.

[0083] The electric push rod 24 is fixed at the base end of the auxiliary frame 23-2, one side of the auxiliary frame 23-2 is fixed with a positioning head 23-3, and the outer circle of the fixed ring 22 is provided with a positioning groove 22-1 and is slidably connected with the positioning head 23-3.

[0084] The cross sections of the positioning groove 22-1 and 22-3 are both T-shaped. This design makes the auxiliary frame 23-2 and the fixed ring 22 have anti-disengagement characteristics.

[0085] The setting of the auxiliary frame 23-2 and the positioning head 23-3 can improve the installation stability of the electric push rod 24, and under the cooperation of the positioning groove 22-1 and the positioning head 23-3, the rotation angle stability of the supporting rod 23 is effectively improved.

[0086] The fixed ring 22 is fixed at the bottom of the long strip, and the outer circle of the receiving seat 21 is provided with a long groove and is slidably connected with the long strip, as shown in the accompanying drawings Figure 5 This design is used to improve the up-down displacement stability of the fixed ring 22.

[0087] The locking sleeve 34-61 is embedded with a touch switch 34-62, which is normally closed and cooperates with an external mechanical interlocking interlocking switch.

[0088] The interlocking switch includes a contact A for controlling the extension work of the electric push rod 24, and a contact B for controlling the retraction work of the electric push rod 24, and the contact A and the contact B cannot be closed at the same time. Among them, the contact A-touch switch 34-62 and the driving part of the electric push rod 24 are connected in series.

[0089] This design can make the touch switch 34-62 trigger after the threaded head 33-8 is screwed into the locking sleeve 34-61, and the electric push rod 24 stops extending. At this time, even if the upper contact A of the interlocking switch is pressed again, the electric push rod 24 cannot extend, but only the contact B can retract, which is used to adapt to the shape of the inner plate template 14 and the inner plate material, without manual adjustment. The whole operation is more rapid and convenient.
