A milling fixture

Abstract

The invention provides a milling clamping tool, which includes a base, a guide block group, an arc claw group, and a screw rod. The head of the base is provided with a milling head installation hole that penetrates the base from top to bottom. The guide blocks are symmetrically and movably installed on both sides of the base. The arc claw group includes several arc claws which are arranged in the lower part of the base and correspond to the guide block group one by one. The connection is disassembled, and the lower end surface of the arc block is adapted to the processing surface of the workpiece to be milled. The device has a simple and reasonable structure, is convenient to use, and has high processing efficiency. By replacing the arc claws adapted to the processing surface of the workpiece, the groove milling can be performed on workpieces with various shapes of processing surfaces, and the utility model has strong versatility.

Description

technical field [0001] The invention belongs to the technical field of clamping tooling, and in particular relates to a milling clamping tooling. Background technique [0002] In the process of modern machinery manufacturing, whether it is in the production of parts in the fields of automobile, aerospace, shipbuilding, etc., it will involve the processing of milling grooves on the surface of the part, especially the tapered surface. Among them, the groove effect may directly affect the overall assembly relationship between parts, and is an indispensable part to realize the overall performance of the mechanism. [0003] For milling grooves of parts made of metal materials, the processing method generally adopted is five-axis machining centers. When five-axis machining centers process parts, a series of preliminary preparations such as modeling, programming, clamping, and positioning are required. , the overall cost of the cycle time is longer, and the production cost is high...

[0003] For milling grooves of parts made of metal materials, the processing method generally adopted is five-axis machining centers. When five-axis machining centers process parts, a series of preliminary preparations such as modeling, programming, clamping, and positioning are required. , the overall cost of the cycle time is longer and the production cost is higher

In the production process of parts, not only parts of metal materials are processed, but also non-metal parts need to be processed and produced. However, due to the processing of non-metal materials in the five-axis machining center, non-metal waste chips are generated. It will block the guide rail of the machine tool, seriously damage the performance and machining accuracy of the machine tool, make maintenance more difficult, and cause greater economic losses

Especially for some workpieces with non-planar processing surfaces, it is more difficult to mill grooves
