Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1-5, an axial and radial adjusting mechanism for a cutting tool comprises a main handle 1, an adjusting ring 2, a connecting handle 3, a tool bar 4, a first threaded hole 5, a hexagon socket head cap screw 6 and a second threaded hole 7, and is characterized in that: the main handle 1 with the connecting surface excircle of connecting handle 3 overlaps there is one adjustable ring 2, be provided with the recess that bears screw extrusion on the adjustable ring 2, the bottom of cutter arbor 4 cut with the circular conical surface of 3 bottom conical surfaces of connecting handle adaptation each other, the cutter arbor 4 is followed 3 front ends of connecting handle insert in the connecting handle 3, the cutter arbor 4 with there is a packing ring on the parallel terminal surface of 3 bottoms of connecting handle, hexagon socket head cap screw 6 passes the packing ring to screw up 4 bottom centers of cutter arbor in the two 7 threaded holes, make the cutter arbor 4 with 3 zonulae occludens of connecting handle. The connection surface of the main handle 1 and the connection handle 3 is provided with corresponding threaded holes and is connected through bolts. The center of the connecting handle 3 is provided with an inner hole penetrating through the center line of the connecting handle 3, the bottom end of the inner hole is provided with a circular conical surface, and the angle which can be extended by the conical hole of the circular conical surface is 7-10 degrees. The inner diameters of other holes except the taper hole of the circular conical surface of the connecting handle 3 are all larger than the diameters of other holes except the taper hole of the circular conical surface of the cutter bar 4 by 4 to 6 wires. The excircle of the front end of the connecting handle 3 is provided with a front threaded hole 5, a rear threaded hole 5, a left threaded hole 5 and a right threaded hole 5 which correspond to each other, and the outer wall of the connecting handle 3 is penetrated by the threaded holes. And the center of the end surface of the bottom end of the cutter bar 4 is provided with a second threaded hole 7.

Firstly, the cutter bar 4 is inserted into the connecting handle 3 from the front end of the connecting handle 3, because the bottom end of the cutter bar 4 is provided with a circular conical surface which is mutually adaptive to the bottom end of the connecting handle 3, the tapered surfaces of the two parts are slightly deformed by compression during the insertion of the tool bar 4 so as to be attached to each other, a gasket is arranged on the parallel end surfaces of the bottom end of the cutter bar 4 and the bottom end of the connecting handle 3, the inner hexagonal bolt 6 penetrates through the gasket and is screwed in the second threaded hole 7 in the center of the bottom end of the cutter bar 4 to realize the tight combination of the cutter bar 4 and the connecting handle 3, then, the connecting handle 3 is installed on the main handle 1 through the corresponding threaded holes on the connecting handle 3 and the main handle 1 by using screws, then the main handle 1 is installed on a main shaft of a machine tool, and finally the adjusting ring 2 is sleeved on the outer circle of the connecting surface of the main handle 1 and the connecting handle 3.

The axial adjustment is performed first, and then the radial adjustment is performed. As shown in fig. 5, the axial adjustment is to adjust the tool holder 4 perpendicular to the actual working surface, 4 screw holes I and 5 corresponding to the 4 screw bolts arranged around the excircle of the connecting handle 3 are used for adjusting the verticality of the cutter bar 4 and the actual working surface, in the adjusting process, the screw in the opposite direction is screwed down when the cutter bar 4 is required to move to, as the diameter of the inner hole of the connecting handle 3 is larger than that of the cutter bar 4, the 4 screws firstly pass through the first threaded hole 5 on the connecting handle 3 to reach a pre-tightening state, and then the corresponding screws are screwed according to the moving direction of the cutter bar 4 which needs to be adjusted, when the screw is tightened, the screw will be pushed against the tool bar 4, which causes the tool bar 4 to move, and when the tool bar 4 is completely perpendicular to the actual working surface, all 4 screws are tightened.

As shown in fig. 1 to 3, the radial adjustment is to adjust the central points of two radial surfaces of the main shank 1 and the connecting shank 3 to be consistent, when the adjusting ring 2 is sleeved on the outer circles of two connecting surfaces of the main shank 1 and the connecting shank 3, the radial runout detection is performed by using a traditional tool runout method, the direction needing the radial adjustment is found by detection, and then the groove on the adjusting ring 2 is squeezed by using a screw to realize the radial adjustment, so that the radial central points of the main shank 1 and the connecting shank 3 are finally consistent.

The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above.
