Tooling for machining cuboid workpiece with three-jaw turning

Abstract

The invention belongs to the technical field of turning tooling, in particular a tooling for three-jaw turning of a cuboid workpiece. The following proposal is now proposed, comprising a main body with a cylindrical structure, and one end of the main body is provided with a mounting groove of a rectangular structure, and the mounting groove One end protruding into the main body is provided with a storage groove coaxial with the main body, the inner wall of the storage groove away from the installation groove is fixed with a positioning rod coaxially arranged with the main body, and the positioning rod is far away from the end of the storage groove The outer ring is fixedly sleeved with a fixed plate, and the two sides of the outer ring of the fixed plate are hinged with lateral guide mechanisms arranged symmetrically along the positioning rods. Set vertical guide mechanism. The invention effectively avoids the eccentric rotation of the workpiece, reduces the vibration amplitude of the workpiece due to eccentricity, improves the stability of the workpiece clamped after processing, reduces the clamping error of the workpiece, and is suitable for the positioning and clamping operation of 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
