Novel linear grating ruler installation structure of vertical tool rest of numerical control vertical lathe

Abstract

The invention discloses a novel linear grating ruler installation structure of a vertical tool rest of a numerical control vertical lathe. The installation structure is composed of a push rod, a grating ruler, a vertical tool rest ram, a vertical tool rest slide carriage, a connecting plate, a linear guide rail and an adjusting pad, wherein the grating ruler is fixedly installed on one side of the front of the vertical tool rest slide carriage through screws; the linear guide rail is installed on one side, close to the grating ruler, of the side face of the vertical tool rest slide carriage through screws; a grating ruler reading head on the grating ruler and a guide rail sliding block on the linear guide rail are fixedly connected by the connecting plate through the screws; the adjusting pad is arranged between the connecting plate and the grating ruler reading head; the lower end of the push rod and the connecting plate are fixedly connected; the upper end of the push rod is fixed at the upper end of the vertical tool rest ram. The conventional installation method of the grating ruler is changed, the grating ruler is installed on one side of the front of the vertical tool rest slide carriage, and the novel linear grating ruler installation structure of the vertical tool rest of the numerical control vertical lathe has the characteristics of good environmental conditions at the installation position of the grating ruler, large installation base plane of the grating ruler, high fixed connection stiffness and the like.

Description

technical field [0001] The invention relates to a novel installation structure of a linear grating scale for a vertical tool post of a numerically controlled vertical lathe, belonging to the technical field of large mechanical equipment. Background technique [0002] The ram of the vertical tool post of the existing CNC vertical lathe moves vertically, and the linear grating ruler generally adopts that the grating ruler is installed on the ram or on the side of the feed box for the vertical movement of the ram. Practice has proved that if it is installed on the ram, it is easy to cause the lubricating oil mist of the guide rail of the ram to soak into the inside of the grating scale, making it unable to work normally. Installed on the side of the feed box for the vertical movement of the ram, due to the limited height of the feed box, when the vertical stroke of the ram is large, most of the grating scale at the upper end of the feed box is in a suspended state, which is eas...

Practice has proved that if it is installed on the ram, it is easy to cause the lubricating oil mist of the ram guide rail to soak into the inside of the grating scale, making it unable to work normally

Installed on the side of the feed box for the vertical movement of the ram, due to the limited height of the feed box, when the vertical stroke of the ram is large, most of the grating scale at the upper end of the feed box is in a suspended state, which is easy to vibrate when the tool holder moves or is caused by cutting Vibration occurs, causing the system to alarm and make it unable to work normally
