Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 , 3 The shown pipe diameter trimming device includes a diameter reducing seat 1, a number of reducing sliders 2 arranged in equal parts on the upper surface of the reducing seat, and a locking sleeve 3 arranged on the periphery of the reducing slider. Such as figure 2As shown, the reducing seat is in the shape of a disk, and a circular boss 11 is arranged at the center of the upper surface of the reducing seat, and a number of slide grooves are arranged radially around the circular boss, so that the reducing slide block and the The reducing seat constitutes the sliding connection in the radial direction of the reducing seat. The sliding groove adopts T-shaped groove, dovetail groove or other existing structures. The number of sliding grooves is generally between 8 and 12. In this embodiment, it is 8. The 8 slide groo...

Abstract

The invention discloses a tube diameter finishing device, which comprises a reducing seat, a plurality of circular reducing sliding blocks and clamping sleeves. The reducing sliding blocks are evenly disposed on the upper surface of the reducing seat. The clamping sleeves are disposed on the periphery of the reducing sliding blocks. The reducing sliding blocks is slidably connected with the reducing seat along the radial direction of the reducing seat. Detachable reducing blocks are disposed on the inner side of the reducing sliding blocks near the center of the reducing seat. The outer face, in contact with the inner wall of the corresponding clamping sleeve, of each sliding block is an inclined face inclined along the central line of the reducing seat. Correspondingly, a clamping inclined face which is matched with the outer face of the corresponding reducing sliding block is disposed on the inner wall of the clamping sleeve. All the inclined faces are enclosed to form a regularly polygonal platform. The tube diameter finishing device is low in wastage, long in service life, compact in structure and convenient in use.

Description

technical field [0001] The invention relates to a mechanical device for processing pipes, in particular to a trimming device for correcting the outer diameter of pipes. Background technique [0002] At present, the automobile industry has become a pillar industry in the national economy, and suspension parts are indispensable for automobile production. Among the suspension parts, the application of rubber suspension parts is very common, and the metal bushings usually need After a trimming process, its diameter is reduced to meet the design requirements. [0003] Existing pipe diameter trimming devices of this type usually include a locking sleeve. The inner surface of the locking sleeve is a conical surface. There are several reducing sliders inside the locking sleeve. The reducing sliders are mounted on a disc-shaped On the base, a number of radial slide grooves are equally divided on the base, so that the reducing slide block can slide and shrink along the radial slide g...
