Problems solved by technology

The central water outlet of the traditional spindle unit is carried out by adding a rotary joint to the broach bar. The structure is complex and the manufacturing cost is high. Especially when the spindle motor requires a direct-coupled structure, the central water outlet needs to use a hollow spindle motor. The cost will increase significantly

Abstract

The invention discloses a central water discharging structure of a main shaft unit and a front end sealing structure of a main shaft. The water discharging structure and the sealing structure are directly machined at the front end of the main shaft; an original front flange cover and an original sealing structure can be used, so that the material cost is low; furthermore, the water discharging structure and the sealing structure are easy to machine and realize; and the front end of the main shaft is more convenient and direct to maintain.

Description

technical field [0001] The invention relates to a central water outlet structure of a main shaft unit and a sealing structure of the front end of the main shaft, in particular to a central water outlet structure of a main shaft unit of a machining center and a sealing structure of the front end of the main shaft. Background technique [0002] In the cutting process, especially when drilling, in order to ensure reliable cooling and lubrication and improve tool life, the way of water outlet from the center of the spindle is usually used to realize the function of water outlet from the center of the tool. The central water outlet of the traditional spindle unit is carried out by adding a rotary joint to the broach bar. The structure is complex and the manufacturing cost is high. Especially when the spindle motor requires a direct-coupled structure, the central water outlet needs to use a hollow spindle motor. The cost increases substantially. Since the front end of the spin...
