A clamping tool for fitter processing

Abstract

The invention discloses a clamping tool for fitter processing, which discloses a support area for the inner wall of the pipe fitting through multiple sets of support ribs, so as to build an effective high-strength internal support structure to ensure that the pipe fitting will not be affected by the external clamping force. The device that is too large to cause deformation is characterized in that the fixed frame is a rectangular frame structure, the two ends of the fixed frame are arched to form arc blocks, and a set of guide grooves are respectively opened at both ends of the fixed frame, at least two A sliding column is placed in a group of guide grooves, and the two ends of the sliding column are respectively fixedly connected with the two sides of the fixed frame, and the two ends of the fixed frame are respectively provided with avoidance grooves, and the wedge-shaped top block is placed in the fixed frame , two sets of supporting ribs are respectively placed on both sides of the wedge-shaped top block, and a chute is opened on the supporting ribs, and the chute corresponds to the sliding post, and one set of supporting ribs is correspondingly inserted in a In the group guide groove, the sliding column is inserted in the chute.

Description

technical field [0001] The invention relates to a clamping tool for fitter processing, relates to a device for strengthening and supporting pipe fittings processed by fitters, and belongs to the field of fitter equipment. In particular, it relates to a device that increases the support area for the inner wall of the pipe fitting through multiple sets of supporting ribs, so as to build an effective high-strength inner support structure and ensure that the pipe fitting will not be deformed due to excessive external clamping force. Background technique [0002] In the fitter work, the vise is often used to clamp and fix the workpiece so that the fitter can process the workpiece. However, when the pipe parts are clamped by the vise, the inner hollow of the pipe lacks a supporting structure, which makes the outer wall of the pipe When clamping, it is very easy to cause deformation of the pipe fittings due to excessive clamping force, destroying its original structural accuracy, a...

[0002] In the fitter work, the vise is often used to clamp and fix the workpiece so that the fitter can process the workpiece. However, when the pipe parts are clamped by the vise, the inner hollow of the pipe lacks a supporting structure, which makes the outer wall of the pipe When clamping, it is very easy to deform the pipe fittings due to excessive clamping force, destroying its original structural accuracy, and if the clamping force is small, it will cause instability in the clamping of the pipe fittings, resulting in the collapse of the workpiece during processing. Dangerous, the existing notification number CN110842820A discloses a thin-walled tube internal support structure, including a first internal support rod, a second internal support rod, a first internal support head and a second internal support head, the first internal support rod and The first inner brace is connected by internal and external threads, the second inner brace and the second inner brace are connected by internal and external threads, and the first inner brace and the second inner brace are cross-connected, but the inner brace structure When supporting the inner wall of the pipe fitting, due to the small number of stress points and narrow distribution area, the inner support force has an uneven effect on the inner wall of the pipe fitting, and the single-point pressure of the inner support force is likely to cause point-shaped protrusions on the pipe fittings
