Three-jaw turning tool for machining cuboid workpiece

Abstract

The invention belongs to the technical field of turning tools, and particularly relates to a three-jaw turning tool for machining a cuboid workpiece. The tool comprises a main body of a cylindrical structure. A mounting groove of a rectangular structure is formed in one end of the main body, and a storage groove coaxial with the main body is formed in the end, stretching into the main body, of themounting groove. A positioning rod coaxial with the main body is fixedly connected to the inner side wall on the side, away from the mounting groove, of the storage groove, the outer ring of the end,away from the storage groove, of the positioning rod is fixedly sleeved with a fixing disc, transverse guide mechanisms symmetrically arranged along the positioning rod are hinged to the two sides ofthe outer ring of the fixing disc, and two vertical guide mechanisms which are symmetrically arranged along the positioning rod are mounted on the sides, close to each other, of two transverse guidemechanisms. With the three-jaw turning tool for machining the cuboid workpiece, eccentric rotation of a workpiece is effectively avoided, the amplitude of vibration of the workpiece due to eccentricity is reduced, the stability of the workpiece after being clamped for machining is improved, the workpiece clamping error is small, and meanwhile tool is suitable for positioning and clamping operationon workpieces of different sizes.

Description

technical field [0001] The invention relates to the technical field of turning tooling, in particular to a tooling for turning a cuboid workpiece with three jaws. Background technique [0002] In the machining industry, many companies mostly use four-jaw chucks as the clamping mechanism when they process cube or cuboid parts. We know that the operation of the four-jaw chuck has the following disadvantages. 1. It takes time to find the center . 2. The position of the hole is completely controlled artificially, which is difficult to control. 3. The stability of product quality during mass production cannot be guaranteed. 4. The technical requirements for operators are relatively high, and generally only experienced masters can operate; [0003] Especially when the workpiece with a rectangular structure is used, it is inconvenient to clamp and position the workpiece. At the same time, the center of the workpiece deviates from the center of the chuck. When the workpiece is ro...

[0002] In the machining industry, many companies mostly use four-jaw chucks as the clamping mechanism when they process cube or cuboid parts. We know that the operation of the four-jaw chuck has the following disadvantages. 1. It takes time to find the center

2. The position of the hole is completely controlled artificially, which is difficult to control

3. The stability of product quality in mass production cannot be guaranteed

4. The technical requirements for operators are relatively high, and generally only experienced masters can operate;

[0003] Especially when the workpiece with a rectangular structure is used, it is inconvenient to clamp and position the workpiece. At the same time, the center of the workpiece deviates from the center of the chuck. When the workpiece is rotated, the eccentricity of the workpiece is serious, and the workpiece is easy to shake, so that the clamping error of the workpiece becomes larger. , the processing progress of the workpiece becomes lower, so a three-jaw turning tool for cuboid workpiece is needed
