Abstract

The invention discloses a grinding head device with a plurality of grinding wheel main shafting, which comprises a grinding head box body, a dynamic and static pressure shafting, a dynamic pressure shafting, an electric main shafting, an oil supply device and a cooling device, wherein the dynamic and static pressure shafting, the dynamic pressure shafting and the electric main shafting are respectively arranged on the grinding head box body; a front end radical support bearing and a back end radical support bearing of the dynamic and static pressure shafting are liquid dynamic and static pressure bearings; a thrust bearing is a liquid dynamic and static pressure bearing; the liquid dynamic and static pressure bearing is respectively connected with the independent oil supply device; the overflow outlet of the oil supply device is connected with an oil pool of the dynamic and static pressure shafting; and a condensing pipe of the cooling device is arranged in the oil pool of the dynamic pressure shafting. With a forced circulation system of main shaft lubricating oil, the dynamic pressure shafting is arranged on the rotatable grind head; and with the dynamic and static pressure shafting, the dynamic pressure shafting and the electric main shafting which are arranged on the grinding head box body, various sand wheels for outer circles, end faces and inner holes for grinding parts such as rotatable bodies can be simultaneously installed to realize the high-speed high-efficiency grilling, the high-precision grinding, and the inner hole grinding of the grinding head.

Description

technical field [0001] The present invention relates to a grinding apparatus, and more particularly, to a grinding head assembly equipped with a plurality of grinding wheel spindles. Background technique [0002] With the industrial adjustment and product upgrading of military industry, aviation, automobile, tools and other industries, the requirements for machine tools are also constantly increasing. The composite processing equipment based on composite processing technology can meet its needs very well. [0003] However, the current grinding head device for compound grinding has certain problems, such as not high enough machining accuracy and efficiency, and difficult oil return for the dynamic and static pressure shaft system used. Contents of the invention [0004] In view of this, the main purpose of the present invention is to provide a grinding head device equipped with multiple grinding wheel spindle systems for high rigidity, high precision and high efficiency co...
