Description

A multi-purpose modular fixture device suitable for CNC machine tools

technical field

This patent relates to the technical field of tooling fixtures for CNC machine tool processing, and mainly relates to a mechanical fixture device with replaceable and fixed sliding blocks.

Background technique

Fixtures are one of the indispensable important process equipment to ensure the quality of machining, improve production efficiency, reduce labor intensity, reduce excessive requirements for workers' skills, and realize the automation of production process. Fixtures installed on the dynamometer can reduce auxiliary time, improve labor productivity, and reduce processing costs. Guarantee processing accuracy and stable processing quality. Reduce the technical requirements for workers, reduce the labor intensity of workers, and ensure safe production. The function of the fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to assist processing or testing. Ordinary machine tool workpiece fixtures can only clamp a single workpiece and require multiple processing on the surface of the workpiece in order to conform to the characteristics of the fixture, which will leave processing marks on the surface of the workpiece and increase the workload at the same time. Therefore, a new type of fixture is needed, which can not only realize clamping at different positions, realize space utilization efficiency, realize as little processing on the workpiece as possible, reduce processing steps, and reduce surface damage to the workpiece, thereby improving work efficiency. It can also be modularized, easy to disassemble, and suitable for workpieces of different sizes.

Contents of the invention

The invention provides a multi-purpose modular clamping device suitable for a numerical control machine tool, aiming to solve the problem that workpieces cannot be conveniently and quickly installed on the machine tool during numerical control machining. Its main features are that it can be used alone, it is easy to disassemble, and it is suitable for workpieces of different sizes. It can realize fast clamping of workpieces, reduce processing steps, and realize multiple uses of fixtures.

Above-mentioned purpose realizes by following technical scheme:

A multi-purpose modular fixture device suitable for CNC machine tools, which consists of: a base, which is characterized in that it is provided with six threaded through holes along the peripheral edge, which are respectively used to connect with the fixture bracket and the machine tool, and the base is provided with The fixture bracket is equipped with four fixed sliders that can move along the radial direction of the support disk.

Four guide grooves are evenly distributed on the fixture bracket, and the four guide grooves are distributed in a cross shape, and each guide groove is equipped with a replaceable positioning slider that can move along the length direction of the guide groove, and the positioning slider The blocks can be replaced according to the diameter of the impeller bottom surface.

The positioning slider is provided with an adjusting bolt at the position connected with the fixture bracket, which is used for quantitatively adjusting the position of the slider, so as to facilitate fastening of the workpiece.

The positioning sliders move back and forth along the length direction of the guide groove, and there are four in total, which can be replaced and together form a supporting surface for supporting the back of the workpiece to be processed.

The center of the base is provided with an inner rod, and the upper and lower ends of the inner rod are processed with threads, respectively connecting the base and the fixture bracket, and the inner rod is covered with a pre-tightening spring.

The inside of the clamp bracket is connected to the base through a pre-tightening spring, which acts as a pre-tightening support for the clamp bracket. A rubber washer is installed at the lower end of the pre-tightening spring, which is beneficial to reducing the vibration of the workpiece during processing.

Beneficial effect:

The invention has a simple and reasonable structure, can adjust the size of the opening according to the actual size of the workpiece to be processed, and is equipped with a replaceable fixed slider according to the radius of the bottom surface of the workpiece, without frequent replacement of fixtures, and can significantly improve the processing efficiency. In the structure of the present invention, a pre-tightened spring is used to connect the base and the fixture bracket, and a rubber ring is provided inside to have a certain vibration damping function, which can obviously improve the processing efficiency of the workpiece in the actual processing process.
