pipe positioning tools

101 and 102. The indexing mechanism 2 includes a fixed base 202 fixed to the work table 1 and a vertical T-shaped rotary shaft 203 forming a rotary pair with the fixed base 202. The lower end of the T-shaped rotating shaft 203 is connected with a rotating cylinder 201 arranged on the working platform 1 and can be driven by the rotating cylinder 201 to rotate 180 degrees around the vertical shaft.

Air cylinders

206 and 207 are respectively arranged on two sides of an upper end plate 210 of the T-shaped rotating shaft 203,

guide rails

208 and 209 are respectively fixed on two sides of the T-shaped rotating shaft 203, and a drilling mechanism 3 and a plug welding mechanism 4 which respectively form a vertical moving pair with the corresponding guide rails are arranged. Specifically, the drilling mechanism 3 and the plug welding mechanism 4 are connected to the telescopic ends of the respective

telescopic cylinders

206, 207 through a Z-shaped bracket 301 and an L-shaped bracket 401, respectively. The Z-shaped support 301 and the L-shaped support 401 respectively form a moving pair with corresponding guide rails, and can be driven by corresponding cylinders to lift as required, so that the drilling mechanism and the plug welding mechanism can respectively lift along the axial direction of the T-shaped rotating shaft 203 as required.

The drilling mechanism 3 comprises a drilling motor 305 arranged on the Z-shaped bracket 301 and a drilling connector 303 fixedly connected with the Z-shaped bracket 301, the drilling motor 305 is in transmission connection with a connecting shaft 302 of a drill bit 304 arranged at the lower end, and the lower end of the drilling connector 303 is in a concave arc shape matched with a pipe material to be processed, so that the pipe material can be clamped and stably positioned.

As shown in fig. 2, the tube positioning tool 101 (or 102) is provided with an L-shaped limit stop 103, which can stop one end of the tube for limiting, so as to achieve the required axial positioning.

An indexing stop block 205 is arranged at the position, adjacent to the rotary fixed seat 202, of the T-shaped rotating shaft 203, and a drilling stop block 204-1 and a plug welding stop block 204-2 are respectively arranged at two sides of the corresponding position of the fixed seat 202.
