The panel positioning seat 10 can support the panel 25. The panel positioning seat 10 is provided with a second bolt 16 for inserting into the hole in the side wall of the panel 25 and a front positioning wall 15 for the panel 25 to abut against. The front pushing cylinders 11 can press the panel 25 against the front positioning wall 15 after being extended. The horizontal bar positioning seat 12 can support the horizontal bar 26. The second lifting platforms 13 are provided with third bolts 14. After the two second lifting platforms 13 are raised, the two third bolts 14 can be raised to positions for positioning the horizontal bar 26. When the horizontal bar 26 is placed on the horizontal bar positioning seat 12, it can be positioned by inserting the two third bolts 14 into the holes on the horizontal bar 26.
[0023] In the embodiment, the structure of the left and right clamping mechanism 9 on the inner side comprises: a first slide 30 that can slide left and right and is installed on the workbench 1 through a linear guide rail, and a first sliding drive mechanism that can drive the first slide 30 to move left and right. A plurality of push blocks are arranged on the first slide 30 in front and back intervals. The first slide 30 moves towards the bottom plate 24 box wall under the drive of the sliding drive mechanism, and the push blocks on it can push and press the bottom plate 24 box wall from the inner side.
[0024] The structure of the front and back clamping mechanism 20 on the inner side comprises: a second slide 31 that can slide forward and backward and is installed on the workbench 1 through a linear guide rail, and a second sliding drive mechanism that can drive the second slide 31 to move forward and backward.

The second slide 31 moves towards the back sealing plate 27 under the drive of the sliding drive mechanism, and the push blocks on it can push and press the back sealing plate 27 from the inner side.
[0025] As shown in Figure 4 The first sliding drive mechanism and the second sliding drive mechanism each comprise: a mounting frame 32 fixed to the workbench 1, a vertical rod 33, an outer connecting rod 34, an inner connecting rod 35, and a cylinder frame 36. The cylinder frame 36 is located below the workbench 1, a cylinder is installed on the cylinder frame 36, one side of the cylinder frame 36 is hinged to the mounting frame 32, the piston rod of the cylinder is fixed to the lower end of the vertical rod 33, the upper end of the vertical rod 33, one end of the outer connecting rod 34, and one end of the inner connecting rod 35 are hinged together, the other end of the outer connecting rod 34 is hinged to the slide, the other end of the inner connecting rod 35 is hinged to the mounting frame 32, a limiting block 37 that can limit the upper end of the vertical rod 33 is arranged on the top of the mounting frame 32, the limiting block 37 can limit the pushing distance of the slide by limiting the upward movement distance of the vertical rod 33, the piston rod of the cylinder retracts to drive the slide to retreat through the outer connecting rod 34, and vice versa. The piston rod of the cylinder extends to drive the slide to move forward through the outer connecting rod 34 to push the push block. In the embodiment, the maximum distance that the limiting block 37 limits the upward movement of the vertical rod 33 is exactly when the outer connecting rod 34 and the inner connecting rod 35 are in a horizontal state and are in a straight line. At this time, the outer connecting rod 34 and the inner connecting rod 35 interact to jointly push the push block. At this time, the outer connecting rod 34 and the inner connecting rod 35 are in a self-locking state, and only when the vertical rod 33 is retracted can the self-locking state of the outer connecting rod 34 and the inner connecting rod 35 be released.
[0026] In actual production, compared with directly pushing with a cylinder, the first sliding drive mechanism and the second sliding drive mechanism have the following advantages: when the air pressure is unstable, the pushing force of the cylinder will fluctuate greatly, so it cannot be reliably pushed. However, in the embodiment, the sliding drive mechanism will be in a self-locking state when the outer connecting rod 34 and the inner connecting rod 35 are in a horizontal state and are in a straight line. At this time, even if the air pressure is unstable, the pushing force of the outer connecting rod 34 and the inner connecting rod 35 will not be loose, so it can be reliably pushed.
