Description

Technical Field

[0001] The invention relates to a pipe joint tapping device, belonging to the field of tapping devices. Background Art

[0002] Tapping is a common metal processing process used to make internal threads on workpieces. By processing the internal threads in the pipe joints in the pipe fittings, it is convenient to install the pipe fittings at one end of the pipe by means of threaded connection. In order to improve the tapping efficiency, multiple clamps are often used to limit the pipe fittings, and then the driving parts are used to drive multiple motors with tapping heads to descend synchronously, so that multiple rotating tapping heads can process the internal threads of the pipe joints in multiple pipe fittings at the same time. During the process of multiple tapping heads tapping multiple pipe joints respectively, if a tapping head fails to work, it is necessary to stop the multiple tapping heads synchronously.

[0012] Beneficial effects of the present invention:

[0013] 1. When a motor fails and cannot drive the corresponding tapping head to rotate normally, the corresponding vertical cylinder is controlled to extend and the corresponding rotating cylinder is controlled to work, so that the pressure arm is separated from the corresponding pipe joint, so that the vertical cylinder drives the connecting column to move downward along the oblong hole through the connecting seat. At this time, the base moves downward, and the pipe joint formed by the spherical head and the pipe joint is separated from the clamp structure formed by the base and the V-shaped seat. Other motors that have not failed can continue to work for tapping operations, avoiding the trouble-free tapping heads from being stuck in the corresponding pipe joints when multiple motors stop working at the same time, thereby reducing the workload of separating the tapping heads from the pipe joints.

[0014] 2. Adjust the spacing between multiple L-shaped plates along the transverse screw rod as needed. At this time, the relative position of the L-shaped plate and the carrier plate changes. When the L-shaped plate moves to the desired position, the first nut is used to limit the relative position of the L-shaped plate and the transverse screw rod, so that the relative position of the L-shaped plate and the carrier plate can be adjusted as needed. The L-shaped plate and the carrier plate are connected by connecting screws, thereby increasing the connection range between the vertical cylinder and the carrier plate and improving the stability of the structure.

[0015] 3. Make the end of the transverse screw pass through the through hole on the support ear, and then use the second nut to limit the relative position of the transverse screw and the support ear to complete the assembly of the transverse screw and the positioning plate. On the one hand, it is convenient to increase the number of L-shaped plates on the transverse screw, and on the other hand, it realizes the convenient disassembly and assembly of the transverse screw and the positioning plate.

[0016] 4. Make the two vertical screws on the horizontal plate pass through the two vertical holes on the positioning plate respectively, and adjust the position of the vertical screws along the vertical holes according to the installation height of the positioning plate. At this time, the spacing between the horizontal plate and the positioning plate changes, that is, the spacing between the positioning plate and the vertical cylinder changes. The limit nut is used to limit the relative position of the vertical screw and the positioning plate, so as to complete the restriction of the relative position of the positioning plate and the vertical cylinder, so as to adjust the installation position of the positioning plate on the carrier plate without changing the layout position of the vertical cylinder. At the same time, it is convenient to adjust the height of the base and the vertical cylinder according to the length of the pipe joint to meet the needs of tapping different pipe joints, and because the height of the base is adjustable, that is, the spacing between the base and the tapping head in the initial state is adjustable, when the base moves downward, when the hydraulic cylinder is fully extended, the depth of the tapping head moving into the pipe joint becomes shorter, and vice versa, the depth of the tapping head moving into the pipe joint increases, so as to achieve the purpose of adjusting the tapping depth in the pipe joint as needed.

The spacing between the multiple L-shaped plates 21 can be adjusted along the transverse screw rod 18 as needed. At this time, the relative position of the L-shaped plate 21 and the carrier plate 11 changes. When the L-shaped plate 21 moves to the desired position, the first nut 20 is used to limit the relative position of the L-shaped plate 21 and the transverse screw rod 18, so that the relative position of the L-shaped plate 21 and the carrier plate 11 can be adjusted as needed, and the L-shaped plate 21 and the carrier plate 11 are connected by the connecting screw 19, thereby increasing the connection range between the vertical cylinder 12 and the carrier plate 11 and improving the stability of the structure.

[0030] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 Two ears 31 are symmetrically connected and fixed on the upper surface of the positioning plate 16. Through holes 30 are opened on the opposite surfaces of the two ears 31. The end of the transverse screw 18 passes through the through hole 30.
