Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.

As shown in fig. 1 to 4, the present invention provides a positive-secondary vertical dual-spindle station apparatus, which includes: base, stand, swivel work head, power sword tower, main shaft and vice main shaft, wherein: the rotary workbench and the upright post are arranged on the base, the rotary workbench can rotate relative to the base, and the upright post is arranged on one side of the rotary workbench; a plurality of stations are arranged on the rotary workbench, and each station is provided with an auxiliary main shaft; the main shaft and the power tool turret are arranged on the upright post, and the main shaft is arranged right above one of the stations of the rotary worktable and can move up and down; the power tool turret can move up and down to process the workpieces clamped by the main shaft and the auxiliary main shaft.

Furthermore, an accommodating cavity is formed in the middle of the base, and a supporting shaft is arranged in the accommodating cavity; the rotary table is mounted on the support shaft through a turntable bearing and is rotatable relative to the support shaft. Each station further comprises a driving motor for driving the workpiece to rotate, and the driving motor is arranged below the rotary workbench. The driving motor is arranged in a space between the inner wall of the accommodating cavity and the supporting shaft.

A plurality of stations are arranged on the rotary workbench and are distributed at equal intervals along the circumferential direction of the rotary workbench.

In more detail, the upright post is a V-shaped upright post, the main shaft is arranged on one inner side surface of the V-shaped upright post, and the power tool turret is arranged on the other inner side surface of the V-shaped upright post. The projections of the workpiece clamped by the main shaft and the workpiece clamped by the auxiliary main shaft on the horizontal plane are superposed. The axis of the main shaft when clamping the workpiece is coincident with the axis of the auxiliary main shaft when clamping the workpiece. When the rotary worktable is provided with N stations, the rotary worktable rotates 360/N degrees every time, wherein N is an integer larger than 1.

More specifically, the main and auxiliary vertical double-spindle stations mainly comprise four parts, wherein the first part is a column 6 part, and the column is locked on the base 1 through bolts. The second part is a sub-main shaft 3 part, which is fixed on the rotary worktable 2 and can rotate along with the rotary table. The third part is a main shaft 4 which is fixed on a vertical column 6 and can move vertically in the vertical direction. The fourth part is a power tool turret 5 which is also fixed on the other surface of the upright post 6 and can also do vertical movement in the vertical direction, meanwhile, the main shaft 4 has the A-axis positioning function, and the power tool turret 5 can also do simple plane milling action.
