Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a tower-type cutter head device of a tool magazine of a comprehensive machining center as shown in figures 1-4, the cutter head is composed of a disk body 1, at least two blades 3, a shaft sleeve 4 and a handle 5, the number of the blades 3 is at least two, the disk body 1 is fixedly welded with the bottom of the shaft sleeve 4, the outer side of the disk body 1 is annularly provided with at least two mounting grooves 2 which are mainly used for mounting the blades 3, simultaneously, the material used for the disk body is reduced, the cost is reduced, the at least two blades 3 are fixedly connected with one side of the inner wall of the corresponding mounting groove 2 through bolts and are used for cutting an object to be processed, the bottom of the handle 5 is annularly provided with a group of clamping pieces 6, the number of the group of clamping pieces 6 is at least more than two even numbers, the balance of the clamping force between the handle 5 and the shaft sleeve 4 can be kept, the width of the group of clamping pieces 6 is reduced from top to bottom, the top of axle sleeve 4 corresponds and has been seted up with chucking piece 6 assorted chucking groove 7, chucking piece 6 uses with the cooperation in chucking groove 7 and can make handle 5 and axle sleeve 4 remain stable fixed, not hard up phenomenon can not appear, chucking piece 6 and the fixed joint in chucking groove 7 that is located on same vertical line, thread groove 9 has been seted up to the bottom annular of handle 5, the top of 4 inner chambers of axle sleeve is equipped with hexagon nut 10, the top that axle sleeve 4 was run through to the bottom of handle 5 is passed through and is passed through thread groove 9 and hexagon nut 10 threaded connection, the cooperation of thread groove 9 and hexagon nut 10 is used and can drive handle 5 and descend, thereby make chucking piece 6 block gradually in chucking groove 7.

Chucking spare 6 comprises two trapezoidal boards 11 and two

springs

12, 11 fixed connection in the bottom of 5 outer walls of handle of two trapezoidal boards, two springs 12 are fixed connection respectively in top and bottom between two trapezoidal boards 11, it is in chucking groove 7 to block into gradually at two trapezoidal boards 11, because the extrusion force that chucking groove 7 both sides inner wall produced two trapezoidal boards 11 respectively makes two trapezoidal boards 11 crooked in opposite directions a little, the compression of spring 12, can utilize spring 12's elastic restoring force to drive two trapezoidal boards 11 and remain the extrusion to 7 both sides inner walls of chucking groove throughout after wearing and tearing appear in two

trapezoidal boards

11 or 7 inner walls of chucking groove, thereby improve the stable strength between handle 5 and axle sleeve 4.

The chucking groove 7 alternates with chucking piece 6 junction position and is connected with wear-resisting bush 8, improves chucking piece 6 and wearability, prolongs chucking piece 6's life, and the top of hexagon nut 10 is equipped with the gasket with disk body 1's junction position, plays a guard action to between hexagon nut 10 and the disk body 1, improves hexagon nut 10's fixed strength simultaneously.

This practical theory of operation: when the cutter head is assembled, the handle 5 is inserted into the through hole at the top of the shaft sleeve 4, and the clamping piece 6 and the clamping groove 7 are kept on the same vertical line, so that the clamping piece 6 is inserted into the clamping groove 7 along with the insertion of the handle 5 into the shaft sleeve 4, then the hexagonal nut 10 is sleeved at the position of the thread groove 9 at the bottom of the handle 5 from the inner cavity of the disk body 1, the hexagonal nut 10 is pulled by using an internal hexagonal wrench, because the hexagonal nut 10 is supported by the top end of the inner cavity of the disk body 1, the handle 5 moves downwards when the hexagonal nut 10 rotates, the handle 5 drives the clamping piece 6 to be gradually clamped into the clamping groove 7 while moving downwards, when the resistance generated between the clamping piece 6 and the clamping groove 7 is greater than the torque force between the hexagonal nut 10 and the thread groove 9, the hexagonal nut 10 cannot rotate again, and simultaneously the clamping piece 6 and the clamping groove 7 are mutually clamped and fixed, so that the handle 5 can be stably fixed on the shaft, and the handle 5 and the shaft sleeve 4 cannot be loosened when the handle rotates due to the clearance between the handle and the shaft sleeve 4.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
