detailed description

The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

As shown in Figure 1, a kind of full-automatic pipe inner wall hydrostatic testing machine of the present invention comprises a pair of clamping mechanisms 1 for clamping pipe 17, a first guide rail 2, a second guide rail 3, several supports 4, a motor 5 reducer 6 and transmission box 7, the top surface of the bracket 4 is a V-shaped groove, the transmission box 7 is provided with a shaft 8, the output end of the motor 5 is connected to the input end of the reducer 6, and the The output end of the speed reducer 6 is connected to the shaft 8 in transmission, the shaft 8 is provided with a first bevel gear 9 and a second bevel gear 10, and the first guide rail 2 and the second guide rail 3 are arranged side by side on the same side of the transmission box 7. On the side, the first lead screw 11 is installed in the first guide rail 2, and the second lead screw 12 is installed in the second guide rail 3, and the first lead screw 11 and the second lead screw 12 are connected to the plurality of brackets 4 in transmission, One end of the first lead screw 11 is fixedly mounted with a third bevel gear 13, one end of the second lead screw 12 is fixedly mounted with a fourth bevel gear 14, and the first bevel gear 9 meshes with the third bevel gear 13 , the second bevel gear 10 meshes with the fourth bevel gear 14, a jacking device for lifting the pipe 17 is installed between the first guide rail 2 and the second guide rail 3, the first guide rail 2 and the second guide rail 3 One clamping mechanism 1 is installed on both sides.
