And the end faces of the support plates 104 and the connecting plates 205 in contact and connection are welded and then finely processed to ensure flatness to stably support the tooling 2. And a forklift inlet for the forklift to lift the tooling 2 is provided between two adjacent support plates 104 in the table 1;

[0028] Two mutually parallel connecting rods 102 are horizontally and fixedly connected between every two adjacent vertical rods 101 on the periphery. A connecting rod 102 is also horizontally and fixedly connected between the two vertical rods 101 in the middle. And all the connecting rods 102 are lower than the tops of the vertical rods 101.

[0029] In this embodiment, four pressing cylinders 3 are fixedly installed on the tooling 2. Two pressing cylinders 3 are symmetrically arranged on the left and right at the position where the sunroof is installed in the middle of the car roof, that is, two pressing cylinders 3 are installed on a cross bar 202. The other two pressing cylinders 3 are arranged on the outside of the car roof, that is, two pressing cylinders 3 are installed on one side of the rectangular frame 201. If there is no sunroof hole in the middle of the car roof, the four pressing cylinders 3 are symmetrically arranged on both sides of the rectangular frame 201. The pressing cylinder 3 includes a cylinder block 305, a piston rod 310, a rotating rod 311, a pressing plate 306, a chain plate 308 and a connecting seat 309. The cylinder block 305 is fixedly installed above the rectangular frame 201 or the cross bar 202. A bottom plate 303 is fixedly installed below the cylinder block 305 through two fixing plates 304. A support rod 302 is fixedly installed below the bottom plate 303. The support rod 302 is mainly used to increase the height of the cylinder block 305, so that the pressing cylinder 3 can clamp from above the car roof.

[0030] A rectangular plate 301 is fixedly installed at the lower end of the support rod 302. The rectangular plate 301 is fixedly installed on the rectangular frame 201 or the cross bar 202. The lower end of the piston rod 310 is installed in the cylinder block 305 in a lifting manner. The lower end of the rotating rod 311 is hinged to the top of the piston rod 310.

[0031] It should be added that, as is well known, the lower end of the piston rod 310 is installed in the cylinder block 305 through a piston for telescoping. When the piston rod 310 in the cylinder block 305 moves vertically upward, the top of the piston rod 310 can drive the lower end of the rotating rod 311 to move upward, so that the rotating rod 311 rotates counterclockwise downward along the upper end of the chain plate 308. For reference, see Figure 5 to achieve the purpose of pressing down the pressing plate 306 to press the upper surface of the car roof.

[0032] In this embodiment, an airbag 307 is fixedly installed on one side of the pressure plate 306, and the airbag 307 is sealed and filled with low-pressure gas. As is known to all, the low-pressure gas is lower than the atmospheric pressure. Therefore, under normal conditions, the outer wall of the airbag 307 is flattened by the external atmospheric pressure, and can automatically deform according to the shape of the outer wall of the automobile roof. The airbag 307 is made of non-elastic and airtight woven fabric, and the outer end surface of the airbag 307 is evenly coated with wear-resistant glue, which is mainly used to prevent the airbag 307 from being cut. A pressure sensor 313 is fixedly connected to one side of the pressure plate 306, and the air inlet of the pressure sensor 313 and the inner cavity of the airbag 307 are connected to each other. The pressure sensor 313 is used to display the pressure of the low-pressure gas in the airbag 307;

[0033] When the pressure plate 306 approaches and presses down the outer wall of the car roof, the airbag 307 is cushioned between the pressure plate 306 and the outer wall of the car roof, and can automatically deform and fit according to the shape of the outer wall of the car roof, so that the clamping is more stable. The clamping force of the pressure plate 306 on the car roof can also be detected by the air pressure sensor 313. When the pressure detected by the air pressure sensor 313 reaches the preset pressure, the air pressure sensor 313 transmits a stop pressing signal to the cylinder body 305 to stop pressing down the pressure plate 306.

[0034] It should be noted that the working process of the easily replaceable supporting device for punching holes in the automobile roof can be referred to Figure 6 .

[0035] The utility model can realize a detachable positioning connection between the table top 1 and the tooling 2 through the positioning clamping of the two positioning pins 105 and the two bushings 206 in the table top 1 and the tooling 2, as well as the positioning contact connection of the four support plates 104 and the four connecting plates 205 in the table top 1 and the tooling 2. Combined with the forklift inlet arranged between the table top 1 and the tooling 2, it is convenient to use a forklift to quickly install and remove the tooling 2 on the table top 1, and the four connecting plates 205 and the two bushings 206 under the supporting tooling 2 used for automobile roofs of different models are compatible with the four support plates 104 and the two positioning pins 105 on the table top 1, which is convenient for compatible replacement of the supporting tooling 2 used for automobile roofs of different models.
