Detailed Description

The present invention will be described in detail with reference to the accompanying drawings. All equivalent changes and modifications made according to the contents of the present specification belong to the technical scope of the present application.

The utility model is used for polishing and chamfering the clamping sleeve and is placed on a tool rest of a lathe, thereby realizing the cleaning and chamfering operation of the inner wall of the clamping sleeve.

Referring to fig. 1, the machining tool for chamfering the clamping sleeve comprises a tool shank 1 and a blade 2, and the blade 2 is fixedly mounted on the tool shank 1 through a screw 3.

Referring to fig. 2, fig. 3 and fig. 7, the tool shank 1 includes a clamping bar 11 and a tool head 12, the clamping bar 11 is located at a lower portion and is fixedly mounted on a tool rest of a lathe, and the tool head 12 is fixedly connected to an upper portion of the clamping bar 11 and is used for mounting the blade 2.

The cutter head portion 12 is a cylinder, and 1/4 parts are removed along mutually perpendicular radial directions; the removed portion 1/4 forms a front cut 111, a side cut 112, and a horizontal cut 113 on the cylinder. The front cut surface 111 and the side cut surface 112 are arranged along the radius of the cylinder and are perpendicular to each other. The horizontal section 113 is perpendicular to the axis of the cylinder, i.e. in a horizontal position.

Referring to fig. 3, 4 and 7, the upper end surface of the tool head 12 is provided with an inner conical bore 115 for guiding the head of the workpiece chuck sleeve, and the half cone angle of the inner conical bore 115 is 45 °. The center of the bottom of the inner conical hole 115 is provided with a convex conical tip 116 for supporting the inner wall of the pipe orifice of the ferrule pipe, and the half cone angle of the tip 116 is 45 degrees, as shown in fig. 4. The apex 116 and the internal conical bore 115 are coaxial with the cylinder of the tool head 12, see fig. 3 and 4.

Referring to fig. 2, 5 and 7, a cutting slot 114 is formed on the front section 111 of the blade portion 12, the cutting slot 114 is square, and a threaded hole 117 for connecting the screw 3 is formed in the center, as shown in fig. 5 and 6.
