Specific embodiment

As shown in figure 1, the utility model proposes a kind of grinding Knife handle structure, including grinding handle of a knife 1 and grind for installing The joint 2 of knife milling tool.

Specifically, as shown in Figures 4 to 6, in the present embodiment, the grinding handle of a knife 1 includes insertion section 11, inlay card portion 12 With the connecting portion 13 for installing, the insertion section 11 is connected by the inlay card portion 12 with the connecting portion 13, wherein, connect Portion 13 is the morse shank specification matched with machine tool chief axis；The inlay card portion 12 is provided with the installation of insertion to the end face of the insertion section 11 Passage 3；The inlay card portion 12 is provided with two caulking grooves 121, and the caulking groove 121 is with the central shaft of inlay card portion 12 as symmetrical axial symmetry Arrange, the tail end of the caulking groove 121 is provided with an insertion groove 122, the end of the opening of the insertion groove 122 in the insertion section 11 On face, the caulking groove 121 and the insertion groove 122 at right angles connect；The inlay card portion 12 is provided with a latch 41, and described slotting The end of pin 41 is located on the central shaft in the inlay card portion 12.

Further, in the present embodiment, its preferred version is：It is provided between the insertion section 11 and the inlay card portion 12 One first chamfering α, is provided with one second undercut ss between the inlay card portion 12 and the connecting portion 13, and the first chamfering α and second is fallen Angle beta is 45 °, it is ensured that the regularity of the grinding outward appearance of handle of a knife 1, it is to avoid big corner angle occur, cause unwanted trouble, while also Can material-saving.Meanwhile, the latch 41 is telescopic thrust screw, is easy to be carried out when joint 2 is connected with grinding handle of a knife 1 Prop up work.And the insertion section 11 is provided with least three floating screws 42, outside of the floating screw 42 along insertion section 11 Radially uniform distribution, and the floating screw 42 insert the insertion section 11 distance it is equal, floating screw 42 can guarantee that and connect 2 all the time on the central shaft of grinding handle of a knife 1.

As shown in Figure 1 to Figure 3, in the present embodiment, the head of the joint 2 is provided with a pair and can be embedded in the caulking groove 121 alignment pin 21；In the present embodiment, its preferred version is：The part of the clamping milling cutter of the joint 2 is collet chuck structure 23.The head of the joint 2 is provided with an arc-shaped slot 22, the center of the centrage of the arc-shaped slot 22 and the alignment pin 21 Axle has one first radial direction angle γ, and the first radial direction angle γ is 25 °, as shown in fig. 6, the end face of the insertion groove 122 Centrage has one second radial direction angle ω with the end face of the latch 41, and the second radial direction angle ω is 25 °.
