Two-freedom-degree concentric-rotating hole-lapping device of ultrahigh back-pressure glass ball

Abstract

Provided is a two-freedom-degree concentric-rotating hole-lapping device of an ultrahigh back-pressure glass ball. A hemi-ball installing disc (10) is installed in an X-axis rotating seat (5), an inner drilling mechanism (6) and an outer drilling mechanism (8) are coaxially and oppositely installed on a rack (1), the X-axis rotating seat (5) is located between the inner drilling mechanism (6) and the outer drilling mechanism (8), a central line plane of the X-axis rotating seat (5) vertically penetrates through a diameter extension line of a Z-axis rotating disc (2), and the middle axes of the inner drilling mechanism (6) and the outer drilling mechanism (8) penetrate through the center of the hemi-ball installing disc (10). The Z-axis rotating disc is mutually matched with the X-axis rotating seat to achieve accurate control of two freedom degrees. In addition, a ball body is coaxially and oppositely clamped by using the inner drilling mechanism and the outer drilling mechanism, a drill bit rotating at high speed is controlled to rapidly advance, work-feed and rapidly reverse for lapping with respect to the center of the ball, rough lapping and finish lapping are performed in a linkage mode, manual hole lapping is completely replaced, and hole-lapping precision and production efficiency are ensured.

Description

technical field [0001] The invention belongs to IPC classification B24B for grinding or polishing machine tools, devices or process technologies, and relates to an auxiliary grinding hole processing device for a glass protective cover of deep-sea shock wave detection equipment, especially a two-degree-of-freedom concentric rotation of an ultra-high back pressure glass ball Grinding device. Background technique [0002] At present, the working environment of seismic wave detection instruments used to detect deep-sea crustal activities is below 10,000 meters above sea level. Since the outside of the protective cover of seismic wave detection instruments needs to withstand a pressure close to 1000KG / square centimeter, that is, ultra-high back pressure, it is an important key component. The cover adopts two ultra-high-strength glass hemispherical structures. Several round holes need to be processed on the glass hemispherical structure of the protective cover for the connection p...
