The No. 1 worm 10 is meshingly connected with the No. 1 worm wheel 8. One end of the No. 1 worm 10 passes through one of the No. 1 fixing seats 9 and is fixedly installed with a No. 1 turning handle 11.

[0031] Two first slide grooves are formed on the top of the workbench 3 , and the four rotating shafts 13 are respectively disposed inside the two first slide grooves and have no contact with the workbench 3 .

[0032] A plurality of springs 15 are fixedly mounted on one side of the fixed plate 14, a pressure plate 16 is fixedly mounted on one end of the plurality of springs 15, a plurality of sliding columns 17 are fixedly mounted on one side of the pressure plate 16, the plurality of sliding columns 17 penetrate the fixed plate 14 and are in sliding contact with the fixed plate 14, and a limiting plate 18 is fixedly mounted on one side of the plurality of sliding columns 17.

[0033] A rotating column 19 is rotatably installed on the inner side of the fixed frame 12, and two No. 1 bevel gears 20 are fixedly installed on the outer side of the rotating column 19. One end of the two rotating shafts 13 passes through the top of the fixed frame 12 and is fixedly installed with No. 2 bevel gears 21. The two No. 1 bevel gears 20 are meshed and connected with the two No. 2 bevel gears 21 respectively.

[0034] One end of the rotating column 19 passes through the fixed frame 12 and is fixedly mounted with a No. 2 worm wheel 22.

[0035] Two second slide grooves are provided on the top of the main frame 1 , and the two moving blocks 5 and the two limiting blocks 7 are respectively arranged inside the two second slide grooves and in sliding contact with the main frame 1 .

[0036] It should be noted that the present invention is a welding table for processing automobile seat accessories. When the square accessories are fixed, the accessories are placed on the top of the workbench 3, and then the No. 1 turning handle 11 is turned to drive the No. 1 worm 10 to rotate, thereby driving the No. 1 worm wheel 8 to mesh and rotate, to drive the bidirectional screw 4 to rotate accordingly, thereby driving the two moving blocks 5 to move in relative directions, to drive the two fixing frames 12 to move accordingly, thereby driving the two fixing plates 14 on the top of the two fixing frames 12 to move accordingly, and then the placed accessories are clamped and fixed by four pressing plates 16, so that the staff can perform welding processing;

[0037] When the circular accessory is fixed, the two No. 2 turning handles 25 are rotated respectively, and the two No. 2 turning handles 25 will respectively drive the two No. 2 worm gears 24 to rotate, thereby driving the two No. 2 worm wheels 22 to mesh and rotate, to drive the two rotating columns 19 to rotate accordingly, to drive the four No. 1 bevel gears 20 to rotate respectively, to drive the four No. 2 bevel gears 21 to mesh and rotate, and then drive the four fixing plates 14 to rotate through the four rotating shafts 13 to adjust the angles of the four fixing plates 14, so as to effectively clamp and fix the circular accessory. When the triangular accessory is fixed, one No. 2 turning handle 25 is rotated alone, so that the angles of two of the fixing plates 14 are changed to match the angles of the corner tips of the triangle, and the other two fixing plates 14 remain unchanged to match the flat parts of the triangle, so as to effectively fix the triangular accessory. When fixing a smaller accessory, it is only necessary to place the smaller accessory between two of the fixing plates 14 for clamping and fixing, thereby improving the use effect of the device.

[0038] like Figure 5 - Figure 6 As shown, in order to better adapt to the clamping of different car seat accessories and accessories of different shapes, the present invention also includes an air layer clamping mechanism, which includes an inflatable layer 27, an adjustment stud 28, an adjustment nut 29, an impact zone center line 30, an impact zone surrounding elastic line 31, a fastening suction cup 32, and an impact zone 33. The inflatable layer is arranged on the clamping side of the pressure plate 16. The inflatable layer 27 is provided with a plurality of impact zones 33. The impact zone 33 includes an impact zone center line 30 and an impact zone surrounding elastic line 31. The impact zone center line 30 and the impact zone surrounding elastic line 31 are both arranged inside the inflatable layer 27. One end of the impact zone center line 30 and the impact zone surrounding elastic line 31 are fixed on the outside of the inflatable layer 27. The other end is fixed to one end of the adjusting stud 28, and the adjusting stud 28 passes through the inner side of the inflatable layer 27. The pressing plate 16 is provided with a corresponding threaded hole. The adjusting stud 28 cooperates with the threaded hole to extend out of the pressing plate 16, and the adjusting nut 29 cooperates with the outer end of the adjusting stud 28 to prevent the adjusting stud 28 from loosening. Working process: Due to the different shapes of the surfaces to be clamped of the automobile seat accessories, in order to better fit the automobile seat accessories than the traditional inflatable layer 27, the inflatable layer 27 is provided with a plurality of influence areas 33. The adjusting studs at the corresponding positions are adjusted according to the shapes of the surfaces to be clamped of the automobile seat accessories, so as to tighten or prevent the looseness of the central line 30 of the influence area and the elastic line 31 around the influence area, so as to shrink or restore the inflatable layer at the corresponding position, so as to better match the shape of the accessories and achieve better clamping.

[0039] Furthermore, in order to prevent the influence area from being too large, there are multiple elastic lines 31 around the influence area, and a single elastic line 30 in the center of the influence area. On the outside of the inflation layer 27, the elastic lines 31 around the influence area are arranged in multiple circles around the center of the influence area 30. The farther the elastic lines 31 around the influence area are from the center of the influence area 30, the greater the elasticity. Thus, the smaller the influence area is, thereby avoiding the influence area being too hard as a whole and lacking smoothness, thereby failing to achieve better clamping.

[0040] Furthermore, since there are more influence zones 33 in the middle of the inflation layer 27, the smaller the radius, the fewer influence zones 33 are on the upper and lower sides, and the larger the radius, the inflation layer 27 can be adjusted more finely in the clamping area, while the clamping surfaces on both sides are used less and the number can be reduced.

[0041] Furthermore, a plurality of fastening suction cups 32 are evenly arranged on the outside of the inflatable layer 27, and the fastening suction cups 32 cooperate with the deformation of the influence zone 33, so that the fastening suction cups 32 are better perpendicular to the surface of the car seat accessories, thereby achieving better adsorption of the car seat accessories by the fastening suction cups 32. The fastening suction cups 32 of the present invention work synergistically with the influence zone, and compared with the traditional flat-arranged suction cups, the suction cups in the influence zone 33 undergo a slight angle change, thereby better adsorbing the accessories.

[0042] Furthermore, if Figure 7 In order to prevent the car seat accessories from accidentally falling and damaging the surface of the equipment platform, the present invention also provides a protection structure, which includes a back plate 34, an inclined plate 35, an airbag 36, a one-way valve 37, and a plane air cushion 38. The back plate 35 is arranged at the lower end of the pressure plate 17, and one end of the inclined plate 35 is hinged to the inner side of the back plate 34. An airbag 36 is arranged between the lower end of the inclined plate 35 and the back plate 34. A plane air cushion 38 is arranged on the surface of the workbench 3, and the plane air cushion 38 is connected to the airbag 36 through a gas pipeline. The gas pipeline is provided with a one-way valve 37 to prevent the gas of the plane air cushion 38 from flowing back to the airbag 36. Working process: when the car seat accessories accidentally fall, the inclined plate 35 is squeezed, and the inclined plate 35 squeezes the airbag 36. There is no gas in the plane air cushion 38 initially. The gas squeezed from the airbag 36 flows to the plane air cushion 38, thereby realizing the secondary buffering of the car seat accessories.
