AI Technical Summary

Technical Problem

In existing technologies, external tooth machining requires multiple tool changes, resulting in a long processing time.

Method used

Design a dental cutter with a cutting head that includes a cutting section and a trimming section. When cutting, the trimming section simultaneously contacts the external tooth, achieving simultaneous cutting and trimming, thus reducing the number of times the cutting head needs to be replaced.

Benefits of technology

By simultaneously opening the threads and trimming the diameter, the number of tool changes is reduced, processing efficiency is improved, and time is saved.

Description

Technical Field

[0001] This utility model relates to the technical field of thread cutting on lathes, specifically a thread cutting tool. Background Technology

[0002] Before machining the external threads of a product, a thread cutter is used to cut the outer diameter of the area to be machined to the corresponding size (rough turning). Then, the external threads are machined. After the external threads are formed, an external diameter cutter is used to repair the external thread diameter to ensure the external thread diameter size, and at the same time, remove the internal burrs from the repair process.

[0003] For the above technical conditions, since the external diameter must be controlled by the external diameter cutter, when repairing the external diameter, it is necessary to change the external feed cutter, which results in a longer time consumption.

[0004] Based on this, the present invention designs a dental knife to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thread cutter, comprising a cutting head for threading a workpiece, the cutting head comprising a mounting part, a thread cutting part, and a diameter trimming part, the thread cutting part and the diameter trimming part being fixedly disposed on the mounting part, two diameter trimming parts being provided, the thread cutting part being located between the two diameter trimming parts, and when the thread cutting part performs thread cutting, the diameter trimming part abuts against the external teeth of the workpiece.

[0006] By adopting the above technical solution, when the tooth is being opened, the caliper is simultaneously pressed against the external tooth, thus allowing for simultaneous tooth opening and caliper ...

[0007] Preferably, the cross-section of the toothed portion is in the shape of an isosceles trapezoid.

[0008] By adopting the above technical solution, the bottom cross section of the alveolar bone is trapezoidal during tooth opening, which improves the strength of the tooth.

[0009] Preferably, the cutter head is provided with multiple opening sections.

[0010] By adopting the above technical solution, different positions of the cutter head can be switched to facilitate the switching of different sizes of dental openings.

[0011] In summary, this application has the following beneficial technical effects: when the tooth is being opened, the caliper is simultaneously against the external tooth, thus allowing for simultaneous tooth opening and caliper ... Attached Figure Description

[0012] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] Figure 1 This is a schematic diagram of the overall structure of the cutter head in this embodiment;

[0014] Figure 2 This is a schematic diagram of the structure of the dental opening in this embodiment.

[0015] The attached diagram lists the components represented by each number as follows:

[0016] 1. Cutting head; 2. Mounting section; 3. Thread cutting section; 4. Diameter trimming section. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] The following is combined with Figure 1-2 This application is described in further detail.

[0019] A thread cutter includes a cutting head 1 for threading a workpiece. The cutting head 1 includes a mounting part 2, a threading part 3, and a trimming part 4. The threading part 3 and the trimming part 4 are respectively fixedly mounted on the mounting part 2 and are integrally formed with the mounting part 2. There are two trimming parts 4, and the threading part 3 is located between the two trimming parts 4. When the threading part 3 performs threading, the trimming part 4 abuts against the external teeth of the workpiece.

[0020] When the tooth is being opened in the tooth-opening section 3, the diameter-reducing section 4 simultaneously abuts against the external tooth, thus opening the tooth and reducing the diameter at the same time. This eliminates the need to replace the cutter head 1 for diameter reduction later, thereby reducing the time spent.

[0021] The cross-section of the tooth opening 3 is an isosceles trapezoid. After the tooth opening is performed, the bottom cross-section of the alveolar bone becomes trapezoidal, thereby increasing the strength of the tooth.

[0022] The cutter head 1 is equipped with multiple opening sections 3. By switching different positions of the cutter head 1, it is convenient to switch between opening sections 3 of different specifications.

[0023] The implementation principle of this embodiment is as follows: when the tooth opening section 3 is opening the tooth, the diameter trimming section 4 simultaneously trims the outer diameter of the opened tooth, eliminating the need to switch to the diameter trimming cutter for additional trimming, thus reducing the time spent.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
