Metal piece casting post-processing efficient grinding apparatus and machining method thereof

Abstract

The invention discloses a metal piece casting post-processing efficient grinding apparatus. The apparatus comprises a column, a bed, a working bench, a spindle box, grinding heads, frequency conversion main motors and clamps. One side of the column is connected to the spindle box. The multiple frequency conversion main motors are arranged at the top portion of the spindle box. Multiple couplings corresponding to the frequency conversion main motors are disposed inside the spindle box. A spindle is arranged between each coupling and the corresponding frequency conversion main motor. The multiple grinding heads are arranged at the bottom portions of the spindles. The working bench is arranged below the grinding heads. The multiple clamps are arranged between the working bench and the grinding heads. According to the invention, a wet processing manner is carried out with a stable feeding speed, the mechanized operation for casting post-processing grinding is achieved, the labor intensity of workers is greatly reduced, the production efficiency is improved, manpower and cost are reduced, and environment pollution and potential safety risks such as fire hazards and dust explosion all caused by dust can be avoided.

Description

technical field [0001] The invention relates to the field of post-processing of parts, in particular to a high-efficiency grinding device for post-processing of metal parts after casting. Background technique [0002] Casting technology is one of the main methods of obtaining mechanical product blanks. It is an important basic technology of the machinery industry and occupies an important position in the national economy. The current situation of my country's casting technology is that the output is large, with an annual output of about 12 million tons of castings, which is comparable to that of the world. Compared with the foundry technology in developed countries, the environmental pollution is serious, especially the safety hazards such as fire and dust explosion accompanied by a large amount of dust generated in the process of cleaning the burrs of castings. [0003] Casting has always been a traditional industry with heavy physical strength, heavy pollution and high inte...

Problems solved by technology

[0004] At present, most of the automatic grinding and cleaning machines produced in China adopt pneumatic-hydraulic hybrid control or full hydraulic control. The control system is mainly divided into traditional relay control mode or PLC control mode. The main problems of this type of equipment are: 1. Grinding A large amount of dust will have a degrading effect on the executive components of the hydraulic system such as the hydraulic cylinder lever and the rubber ring, which will aggravate the wear and cause a high failure rate; If you want to change the part number, you need to adjust the electrical switch, and all the fixtures need to be disassembled and replaced, resulting in low productivity; A large amount of dust and noise generated during the process seriously pollute the environment and the health of the operators

[0005] Most developed countries such as Japan and Germany adopt highly automated robot grinding units or automatic grinding equipment to completely replace labor. Compared with domestic manufacturing equipment, foreign imported equipment has excellent performance, but the price is high, and the follow-up maintenance cost is high. , resulting in equipment costs higher than labor costs, and many companies are still unable to popularize the use of
