Description

Technical Field

[0001] The utility model belongs to the technical field of circular cutters, in particular to a circular cutter. Background Art

[0002] Cutting tools are tools used for cutting in mechanical manufacturing, also known as cutting tools. Since the cutting tools used in mechanical manufacturing are basically used to cut metal materials, the term "cutting tool" is generally understood to refer to metal cutting tools.

[0003] Loading refers to the process of sending the workpiece to the working position and achieving positioning and clamping. During the loading process, the workpiece needs to be cut to facilitate subsequent loading. The tools in existing loading equipment are mostly rectangular structures. Although they can cut, if used for a long time, the force on the back of the tool will be low, which will cause the tool to break or be damaged, greatly reducing the scope of application of the tool. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a circular cutter, which can effectively solve the problems of the prior art.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a circular cutter, comprising a cutter body and a cutting blade arranged outside the cutter body, and further comprising:

[0007] The limiting groove is symmetrically arranged on the left and right sides of the upper end surface of the knife body, and the inner side of the limiting groove is clamped with a connecting piece;

[0008] The locking mechanism is arranged at the lower end of the knife body and is used to limit the position of the knife body.

[0009] Furthermore, the locking mechanism includes a connecting groove, a screw body, a base plate body and a positioning nut. The connecting groove is opened inside the knife body, and the connecting groove is arranged in a triangular shape. The screw body is fixed to the lower end face of the connecting piece, and the screw body is slidably engaged in the inner side of the connecting groove. The base plate body is slidably engaged in the inner side of the limited groove. The positioning nut is arranged on the lower end face of the base plate body, and the positioning nut is threadedly connected to the screw body.

[0010] Furthermore, limiting sliding grooves are symmetrically provided at the upper and lower ends of the connecting groove, and the cross section of the limiting sliding groove is a diamond-shaped structure.

[0011] Furthermore, a connection slot is provided on the lower end surface of the bottom plate body, the connection slot corresponds to the position of the connection groove, and the positioning nut can be located inside the connection slot.

[0012] Furthermore, the outer surface of the cutting blade is evenly provided with knife edge grooves, the knife edge grooves are arc-shaped structures, and the diameters of the knife edge grooves increase one by one in a clockwise direction.

[0013] The utility model has the following beneficial effects:

[0014] The utility model arranges the knife body to be a circular ring structure, so that the back side of the knife body can be subjected to greater force, thereby avoiding breakage or damage during long-term working conditions and prolonging the service life of the knife body. Then, the screw body at the lower end of the connecting piece can pass through the bottom plate body and be connected with the positioning nut, so as to limit the position of the knife body and avoid the knife body from deflecting and shaking. At the same time, due to the different diameters of the blade grooves, workpieces of different diameters can be cut, which can facilitate subsequent loading and further improve the scope of application of the equipment.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-4As shown, the utility model is a circular cutter, comprising a cutter body 1 and a cutting blade 2 arranged outside the cutter body 1, and further comprising:

[0024] The limiting groove 3 is symmetrically provided on the left and right sides of the upper end surface of the knife body 1, and the inner side of the limiting groove 3 is clamped with a connecting piece 4;

[0025] The locking mechanism is arranged at the lower end of the tool body 1, and is used to limit the position of the tool body 1; the locking mechanism includes a connecting groove 6, a screw rod body 7, a bottom plate body 8 and a positioning nut 10. The connecting groove 6 is opened in the interior of the tool body 1, and the connecting groove 6 is arranged in a triangular shape. The screw rod body 7 is fixed to the lower end surface of the connecting member 4, and the screw rod body 7 is slidably engaged with the inner side of the connecting groove 6, and the bottom plate body 8 is slidably engaged with the inner side of the limiting groove 3. The positioning nut 10 is arranged on the lower end surface of the bottom plate body 8, and the positioning nut 10 is threadedly connected to the screw rod body 7. The setting of the connecting groove 6 can facilitate the subsequent insertion of the screw rod body 7, and the bottom plate body 8 can be sleeved on the outer side of the screw rod body 7. Then, the positioning nut 10 is threadedly connected to the outer side of the screw rod body 7. Since one side of the positioning nut 10 contacts the bottom surface of the bottom plate body 8, the tool body 1 can be quickly connected. Since the screw rod body 7 is provided with three groups, the connection effect of the tool body 1 can be guaranteed by three-point positioning to avoid deviation and shaking.

[0026] The lower end surface of the base body 8 is provided with a connecting slot 9, which corresponds to the position of the connecting groove 6, and the positioning nut 10 can be located inside the connecting slot 9. The setting of the connecting slot 9 can limit the position of the positioning nut 10, which can prevent the positioning nut 10 from offsetting and shaking, thereby affecting subsequent processing; the upper and lower ends of the connecting groove 6 are symmetrically provided with limiting slide grooves 5, and the cross-section of the limiting slide groove 5 is a diamond structure, and the setting of the connecting groove 6 can be engaged with the connecting piece 4 and the protrusion on the inner side of the base body 8, which can ensure the connection effect of the knife body 1 with the connecting piece 4 and the base body 8.

[0027] The outer surface of the cutting blade 2 is evenly provided with a blade groove 11. The blade groove 11 is an arc-shaped structure and the diameter of the blade groove 11 increases one by one clockwise. By setting the blade groove 11 with different diameters, workpieces of different diameters can be cut, which can facilitate subsequent loading and further improve the scope of application of the equipment.
