Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, and the utility model is further explained below.

As shown in fig. 1-2, a spindle head includes a fixed end 1, and a housing 2 mounted on the fixed end 1. Stiff end 1 is used for with the stand movable mounting of lathe seat, and concrete mounting means does, sets up the lead screw structure in the stand, is equipped with the cover on stiff end 1 in order to realize the lead screw cover of mutually supporting on the lead screw, rotates through the motor drive lead screw that installs the correspondence on the lathe seat, and then realizes the lift of the lead screw cover by the vertical slip support of stand on the lathe seat.

A transmission assembly 3 is arranged in the box body 2; the transmission assembly 3 comprises a first transmission rod 301 and a second transmission rod 303 which is connected with one end of the first transmission rod 301 through a universal joint 302; the other end of the first transmission rod 301 and the other end of the second transmission rod 303 are respectively provided with a first bevel gear 304 and a second bevel gear 305. The first bevel gear 304 is connected with a driving machine mounted on the machine tool base, and specifically, the motor and a gearbox used in cooperation with the motor are used as the driving machine, and a bevel gear transmission set is adopted to drive the first bevel gear 304 and the first transmission rod 301. The second bevel gear 305 meshes with the teeth structure of the drive bit, which is also a bevel gear, and meshes with the second bevel gear 305.
