Special-shaped pipe joint locating device

Abstract

The invention discloses a special-shaped pipe joint locating device so as to locate a work-piece accurately and stably. The special-shaped pipe joint locating device comprises a clamp body which is provided with a working table used for locating the bottom face of the work-piece. The clamp body is in an L shape after being turned over horizontally. The working table is located above the horizontal transverse edge of the clamp body. A transverse rocking rod is arranged above the vertical edge of the clamp body and hinged to a support. The support is connected above the vertical edge of the clamp body in a threaded mode. An upper clamping claw for locating the upper surface of the work-piece is hinged to the middle of the rocking rod. A side clamping claw is hinged to the end of the transverse edge of the clamp body in the side direction. A clamping part of the side clamping claw corresponds to the side direction of the work-piece. A pulling rod is hinged to the free end of the rocking rod and connected with a hole in the side clamping claw in a sliding mode. The portion, penetrating through the side clamping claw, of the pulling rod is provided with a thread and connected with a nut.

Description

technical field [0001] The invention relates to a special-shaped pipe joint positioning device. Background technique [0002] The concept of special-shaped steel pipe, rectangular pipe, square pipe sharp corner: special-shaped steel pipe, rectangular pipe, square pipe The traditional welded stainless steel square rectangular pipe is usually produced with a Turkish head roll and several square rectangular rolls. The production mainly depends on flat roll rolling and shaping. Since the flat roll is a two-roll structure, there are problems of unequal roll gaps at the four corners of the square and rectangular tubes and inconsistent force states at the corners, resulting in inconsistencies in the four corners of the square and rectangular tubes. Points vary, R=1.2t, the rectangular tube ruler is the radius of the outer fillet, and f is the wall thickness. Although it meets the relevant enterprise standards, it cannot meet the user's high-quality requirements for products. The ...

Problems solved by technology

The shortcoming of this scheme is: 1, the production cycle is long

2. Repeated disassembly and installation of the spindle connection plate will reduce the dimensional accuracy of the spindle and connection plate, and affect the machining accuracy of subsequent conventional shaft workpieces

3. Due to the different models of machine tools, the interface types and sizes of the spindle and connecting discs will be different, resulting in different structural sizes and types of faceplates.
