Machine tool special for machining gamma-knife spherical cap focusing holes

Abstract

The invention relates to a machine tool special for machining gamma-knife spherical cap focusing holes. The machine tool comprises a base, a protruding plate is arranged in the center of the base, a forming drum is installed on the outer wall of the protruding plate in a matched mode, a height control clamping groove is formed in the inner wall of the forming drum, a pressing plate is arranged on the height control clamping groove, a stand column is fixedly installed in the center of the pressing plate, and multiple balancing weights which are different in diameter are installed on the stand column in a sleeving mode. The invention aims at solving the technical problem of providing a test die which is directly formed by mixed concrete and simulates corresponding forming pressure, the test requirements can be met, and meanwhile the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of machine tool devices, in particular to a special machine tool for gamma knife spherical crown focusing hole processing. Background technique [0002] like Figure 3-4 The picture shown is a part of the medical equipment---Gamma Knife (there are many kinds of similar parts), and the focusing accuracy of the focusing hole on the spherical crown is very high. The traditional processing method is: design and manufacture a set of fixtures, and perform drilling and boring processing on a high-precision horizontal coordinate boring machine. Its disadvantages are as follows: 1. The design of the fixture is complicated, the precision requirement is high, and the production is difficult; 2. The versatility of the fixture is poor. There are many kinds of parts similar to the spherical crown focusing hole, and many kinds of fixtures are required; 3. It is difficult to operate and process. Every time a type of processing part...

AI Technical Summary

Problems solved by technology

The disadvantages are: 1. The design of the fixture is complicated, the precision is high, and the production is difficult; 2. The versatility of the fixture is poor

There are many kinds of parts similar to the spherical crown focusing hole, and many kinds of fixtures are required; 3. Difficult to operate and process

Every time a type of processing part is changed, it is necessary to replace the fixture, which is difficult to adjust; 4. The operation and processing of the coordinate boring machine requires high technical level of the operator, and the numerical control cannot be realized, and the processing accuracy is also low; 5. The production efficiency is low.
