Single module positioning guide mechanism

Abstract

A single module positioning and guiding mechanism, characterized in: comprising a pull rod (14), the outer circumference of the pull rod (14) being provided with a cone (1); installed via long T-shaped keys (4) on the outer circumference of the cone (1) is a module (5) that cooperates and slides with the cone; the cone (1) and the module (5) are fixed on the long T-shaped keys (4) via fixing elements; also installed on the outer circumference of the pull rod (14) is a support ring (7); installed between an end surface of the support ring (7) and an end surface of the module (5) are short T-shaped keys (6); installed via a sliding block assembly (3) on the other end surface of the module (5) is a guiding ring (2); multiple T-shaped grooves (8) and square grooves (9) are provided on the ring surface of the guiding ring (2) in equal intervals. The guiding ring effectively ensures that the matching gaps between the T-shaped keys and the surface of the T-shaped grooves on the cone are even, and that the matching gaps between the short T-shaped keys and the T-shaped grooves of the support ring are even. The precision of the equal intervals between the long T-shaped keys, the T-shaped grooves on the cone, the T-shaped grooves on the support ring, and the module on the outer circumference having the pull rod as the axis are ensured. The guiding is effective, the operation reliability of an expanding head is enhanced, and the service life thereof is extended.

Description

technical field [0001] The invention relates to the technical field of diameter expanding equipment, in particular to a single module positioning and guiding mechanism for a diameter expanding head. Background technique [0002] At present, in the expanding equipment, the expanding head is a key component in the expanding equipment. The expansion tool is equipped with an expansion head, which occupies limited space, and has a complex shape and built-in structure. The fixation of the expansion tool ensures that the force on the expansion head is uniform, and the force on the expansion head is: convert the axial movement of the tie rod into direct contact with the steel pipe The radial movement of the pipe wall module eliminates the forming pressure generated during the forming process of the steel pipe and the welding stress generated during welding, and ensures that the diameter of the entire length of the steel pipe is basically the same. [0003] The expanding head in the...

Problems solved by technology

The pressure between the above contact surfaces is high, if the lubrication is poor, the wear will be accelerated, and even the contact surface of the parts will be damaged

In the prior art, there is no positioning device at the small end of the module, its guiding performance is poor, and the accuracy of the circumference equalization cannot reach the best controllable state, its use effect is poor, and the gap between the components cannot be guaranteed
