[0020] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0021] Embodiment 1, in combination with Figures 1-25. A positioning fixture for a whirlwind milling cutter, used to provide a positioning reference for a blade block 2 on a handle 1. The connection structure between the handle 1 and the blade block 2 is as shown in the attached Figure 5 As shown; comprising a mounting sleeve 3 and a connecting sleeve 4; the inner hole of the mounting sleeve 3 is a tapered hole corresponding to the taper of the mounting end of the handle 1, that is, when in use, the handle 1 can be inserted into the mounting sleeve 3, so that the mounting end of the handle 1 is correspondingly adapted to the mounting sleeve 3;

[0022] A connecting sleeve 4 is provided at one end of the mounting sleeve 3 corresponding to the blade handle 1 for mounting the blade block 2; a positioning semi-ring 5 for positioning the blade block 2 is provided at the position of the connecting sleeve 4 corresponding to the blade block 2, and the inner ring surface of the positioning semi-ring 5 is the positioning reference of the blade block 2. When installing or replacing the blade block 2, the blade block 2 can be inserted into the mounting cavity of the blade handle 1 so that the tip of the blade block 2 contacts with the inner ring surface of the positioning semi-ring 5, and then the blade block 2 can be fastened to the blade handle 1 by a locking screw, which is convenient for the operator to quickly install the blade block 2 on the blade handle 1 of the cyclone milling cutter and can ensure the consistency of the installation;

[0023] It should be noted that the connecting sleeve 4 is coaxial with the shank 1, so the radius of the inner ring surface of the positioning semi-ring 5 can be set according to actual needs; for example, if the distance between the tip of the blade block 2 and the center line of the shank 1 is required to be 36 mm, the radius of the inner ring surface of the positioning semi-ring 5 can be 36 mm.

[0024] In addition, the mounting sleeve 3 and the connecting sleeve 4 are split structures, and one end of the mounting sleeve 3 is coaxially plugged into one end of the connecting sleeve 4, that is, the mounting sleeve 3 and the connecting sleeve 4 can rotate relative to each other. When the mounting end of the tool handle 1 is correspondingly adapted to the mounting sleeve 3, the mounting sleeve 3 is not convenient to rotate, and the positioning half ring 5 can be driven to rotate around the axis of the tool handle 1 by rotating the connecting sleeve 4, so as to facilitate the installation and positioning of the tool block 2.

[0025] Embodiment 2: It is found in actual use that after installing the blade block 2 on the handle 1, it is usually necessary to adjust the eccentricity of the handle 1 on the whirlwind milling machine. However, the measurement and verification of the eccentricity are relatively difficult. In order to solve the above technical problems, this embodiment is further improved.

[0026] Combined with Figures 3-4 , a positioning tool for a whirlwind milling cutter, which is different from embodiment 1 in that, on the basis of embodiment 1, the connecting sleeve 4 is provided with a positioning seat 6 at one end corresponding to the positioning half ring 5, and the positioning seat 6 is provided with an installation cavity that can be adapted to the corresponding ends of the positioning half ring 5 and the connecting sleeve 4; the positioning seat 6 is provided with a measuring meter 8 through a bracket 7; combined with the attached Figure 4When measuring the eccentricity of the tool handle 1 on the cyclone milling machine, the positioning seat 6 and the connecting sleeve 4 are assembled accordingly; the tool handle 1 is installed on the main shaft of the milling cutter of the cyclone milling machine, the connecting sleeve 4 is clamped by the three-jaw chuck of the cyclone milling machine, and the eccentricity of the tool handle 1 is measured by the measuring gauge 8. During the measurement, the tool handle 1 is rotated relative to the positioning seat 6; according to needs, the measuring gauge 8 is a micrometer, a dial gauge or a laser rangefinder, which is convenient and quick to use.

[0027] To prevent the positioning seat 6 from accidentally separating from the connecting sleeve 4, one end of the positioning seat 6 corresponding to the connecting sleeve 4 is threadedly connected with a positioning bolt 9 that can contact the connecting sleeve 4. That is, the positioning seat 6 and the connecting sleeve 4 can be fastened and connected accordingly by tightening the positioning bolt 9.

[0028] In order to further ensure the coaxiality of the locating seat 6 and the connecting sleeve 4, the connecting sleeve 4 is provided with an annular boss 10 on one end of the sleeve corresponding to the locating seat 6. The annular boss 10 has a conical structure corresponding to one end of the locating seat 6, and the mounting cavity of the locating seat 6 is provided with a conical cavity corresponding to the annular boss 10. That is, the coaxiality of the locating seat 6 and the connecting sleeve 4 can be effectively guaranteed by the corresponding adaptation of the conical structure of the annular boss 10 and the mounting cavity of the locating seat 6, thereby effectively ensuring the measurement accuracy.

[0029] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
