Described Coupling is provided with the gathering sill that is parallel to top tube axis, in adjusting device, is provided with the gib block that is complementary with gathering sill.In order to keep pushing up the position of wheel, make the top wheel when regulating its can be around the top axis of tube rotate, Coupling is provided with gathering sill, through on the adjustable column of centre frame, gib block being set, matches with gathering sill, the situation of having avoided the top wheel to rotate.
Said adjusting device is provided with rotating disk, and rotating disk is connected with the top wheel through the screw rod in the adjusting device.In order to adapt to the needs of different workpieces, drive the screw rod in the adjusting device through rotating disk, screw rod promotes the top wheel and moves along the diametric(al) of centre frame body, regulates the position of workpiece on the centre frame with this.
The present invention compared with prior art has following advantage and beneficial effect:
The slender piece of 1 machined stock-removing machine of the present invention is to feeling concerned about system; Thimble is installed on slide rail; Centre frame; Pass through chuck; Centre frame; The mode that thimble is fixing with workpiece; Make slender piece on axis, receive three places chucking power radially; Strengthened the rigidity of slender piece; Overcome eccentric problem; The top wheel is installed on the adjusting device of centre frame body; Convert the frictional force between workpiece and the centre frame body to force of rolling friction; Reduced workpiece by the situation of locking, simultaneously, through the drive of rotating disk; Can regulate the active force between top wheel and the workpiece, make workpiece stressed evenly;
The slender piece of 2 machined stock-removing machines of the present invention is to feeling concerned about system; Through on the tube of top, mounting groove being set; Bearing is installed in mounting groove; The mode of suit roller on the bearing; Convert the frictional force between top wheel and the workpiece to force of rolling friction; Reduce workpiece by the situation of locking, helped the processing of workpiece.
