A cnc six-axis linkage machining device for bathroom castings

Abstract

The invention relates to a CNC (Computer Numerical Control) six-axis linked sanitary casting machining device. The CNC six-axis linked sanitary casting machining device is characterized in that the device comprises a body big plate (1), fixtures and body positioning pins (2); the number of the fixtures is six, the six fixtures are installed on the body big plate (1), the number of the body positioning pins (2) is four, and the four body positioning pins are located at the four corners of the body big plate (1) and are used for positioning the body big plate (1); each fixture comprises a first cross-shaped positioning key (3), a left valve chamber positioning device (4), a water inlet positioning device (5), a water inlet positioning sleeve (6), a right valve chamber positioning device (7) and an eccentric cam mechanism (8).

Description

technical field [0001] The patent of the present invention relates to a CNC six-axis linkage machining device for bathroom castings. Background technique [0002] High-end faucet products are mainly made of brass castings, which are called high-end. The most important thing is that the requirements for appearance are quite strict. In its manufacturing process, grinding and polishing the outer surface is an important link. The basic process is: coarse sanding, fine sanding, and polishing. Among them, coarse sanding is an important link to meet the requirements of high-end faucets for surface quality and shape consistency. The role is to determine the shape of the product and evenly remove the slag layer on the casting surface, which is the basis for quality assurance. The best solution at present, on the one hand, is the traditional process, which is completed by high-skilled manual operation. The disadvantage is worker training. The proficiency period is long, the labor int...

Problems solved by technology

In its manufacturing process, grinding and polishing the outer surface is an important link. The basic process is: coarse sanding, fine sanding, and polishing. Among them, coarse sanding is an important link to meet the requirements of high-end faucets for surface quality and shape consistency. The function is to determine the shape of the product and evenly remove the slag layer on the casting surface, which is the basis of quality assurance. The best solution at present is the traditional process method, which is completed by high-skilled manual operation. The disadvantage is worker training. The proficiency period is long, the labor intensity is high, the working environment is poor, the production efficiency is low, the labor resources are increasingly scarce, and it is difficult to ensure the accuracy and consistency of the product shape; on the other hand, it uses robot polishing, and its basic process is manipulator The workpiece is clamped, and through the space movement of 6 degrees of freedom, the shape of a product is polished in several steps on different types of sanding machines. The production efficiency is basically the same as that of manual operation.

The disadvantage is that the technology is difficult, the preparation work in the early stage of production is complicated, the main equipment needs to be imported, the one-time input equipment cost and production maintenance cost are high, and the complex shape product cannot adapt to all surface processing; this is a common problem faced by the high-end faucet manufacturing industry.
