Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a shaft pin hole positioning device for a handle of a numerical control machine tool. Background Art

[0002] There are one or more speed regulating handles on the exterior of CNC machine tool boxes. In order to properly adjust to the appropriate position of each gear and make the label and the handle shaft match properly, the position of the pin hole on the handle has a high position requirement. In the mechanical processing industry, high-precision equipment is used for high-precision parts processing, and rough processing equipment is used for rough processing of parts.

[0003] After searching, the applicant found that a Chinese patent disclosed "a component fine shaft pin hole positioning device", and its publication (announcement) number is "CN202045595U". This patent is mainly fixed to a vertical panel of an L-shaped plate through four adjusting fastening screws, and a support seat is installed on the bottom surface of the L-shaped plate. The components to be processed are placed on the top of the support seat. There is a U-shaped groove on the upper center line of the vertical panel of the L-shaped plate, which is used to fix the parts that cooperate with the components to be processed. However, the device is not convenient for fixing according to the length of the parts, so that the pin hole positioning device cannot adapt to shaft pins of different lengths. For this reason, we propose a shaft pin hole positioning device for CNC machine tool handles. Utility Model Content
