Detailed Description

As shown in fig. 1 to 6, the present invention mainly includes a frame 1, a clamping unit and a drilling unit, and the present invention is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the frame 1 has a rectangular parallelepiped structure, and the bottom of the frame is provided with legs 11. A groove 12 is arranged in the front side wall of the rack, the groove penetrates through the front side wall and the upper side wall of the rack, the upper half part of the groove is rectangular, and the lower half part of the groove is semicircular. A mounting groove 13 is also provided in the upper surface of the frame, the mounting groove being located at the rear side of the recess.

The clamping unit is arranged on the frame and comprises an adjusting motor 21 arranged in the frame and a supporting shaft 2 fixed at the output end of the adjusting motor, and the supporting shaft 2 is in threaded connection with the output end of the adjusting motor as shown in fig. 2. When the adjustable support shaft is used, a casting part is placed on the support shaft, and the support shaft with the required outer diameter is selected to be installed at the output end of the adjusting motor according to the size of a center hole of the casting part. The front end of the supporting shaft is conical so as to facilitate the placement of a casting piece. The casting is mounted on the support shaft and is also placed in the groove.
