Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing tools, and in particular relates to a processing tool designed with a groove. Background Art

[0002] In daily blank processing and production, different tools may be used for rough and fine processing on each surface to be processed, which requires more tools and a longer overall process, resulting in low production efficiency and higher processing costs.

[0003] Some machined parts have some special-shaped structural features, which are often important key features and require precision during processing. For example, in the past, we usually process the structure with a round protrusion in the middle by using a ball-end cutter or wire cutting. This processing method has poor precision, low efficiency, many processes and high cost. Therefore, it is necessary to design a tool for the product structure that needs to be formed, so as to improve efficiency in medium and large-scale production. Utility Model Content

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A machining tool designed with a groove comprises a tool body, characterized in that the tool body consists of a handle portion and a blade portion, the blade portion is integrally formed at one end of the handle portion, the handle portion is a cylindrical structure, and an annular groove is designed and formed on the blade portion, with the annular groove as the boundary, the cross-section of the upper half of the blade portion is square, and the cross-section of the lower half is trapezoidal; the blade portion has a total of four machining surfaces.

[0006] Preferably, the diameter of the shank portion ranges from Φ7.5 mm to Φ8.5 mm.

[0007] Preferably, the wall surface of the annular groove is one of the four processed surfaces of the blade portion, and its formed size range is between R0.5 and R0.9.

[0008] Preferably, the maximum diameter of the blade portion ranges from 12.5 mm to 9.5 mm, and the minimum diameter ranges from 9.6 mm to 10.6 mm.

[0009] Preferably, the height dimension of the blade portion ranges from 7.5 mm to 8.5 mm.

[0010] Preferably, the overall length of the tool body is between 26 mm and 29 mm.

[0011] Preferably, the four processing surfaces of the blade portion are respectively the first processing surface, the second processing surface, the third processing surface and the fourth processing surface, and the connecting edges between the first processing surface and the second processing surface, the second processing surface and the third processing surface, and the third processing surface and the fourth processing surface are all rounded edges.

[0012] Compared with the prior art, the advantages of the present invention are: the processing production based on the milling forming method of the present invention can effectively improve its work efficiency, because it is a tool designed for products of specific shapes, and can process and form the shape through a single pass. In terms of processing convex grooves and convex edges, compared with using a multi-ball end tool to feed a small number of times, it has significant advantages in tool change efficiency, tool setting time, and processing pass time, and it can achieve rough processing, semi-finishing and finishing by adjusting the feed amount to ensure that it can process the blank from the blank to the finished product or semi-finished product, thereby achieving the purpose of improving efficiency and reducing time costs.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 3As shown, the utility model is a processing tool designed with a groove. The utility model is a processing tool specially designed for processing requirements. It is a tool body (1) composed of a handle part (2) and a blade part (3), wherein the blade part (3) is integrally formed at one end of the handle part (2), the handle part (2) is a cylindrical structure, and the blade part (3) is designed and formed with an annular groove (30). With the annular groove (30) as the boundary, the cross section of the upper half of the blade part (3) is square, and the cross section of the lower half is trapezoidal. There can be at most four grooves on the blade part (3). The first processing surface (31), the second processing surface (32), the third processing surface (33) and the fourth processing surface (34) are respectively processed surfaces, and considering the beauty and safety of the product after molding, the connecting edges between the first processing surface (31) and the second processing surface (32), the second processing surface (32) and the third processing surface (33), and the third processing surface (33) and the fourth processing surface (34) are all rounded edges. Such a design can ensure that the molded product is integrally molded with chamfers without the need for additional tool change processing, which saves time and improves production efficiency to a certain extent, and also reduces the loss that may occur in subsequent chamfering.

[0018] It is worth noting that the utility model designs and forms an annular groove (30) on the blade portion (3) to cooperate with the processing, so as to form a structure that is difficult to form with other conventional tools of the ball knife at one time, such as Figure 3 The sink cavity structure with a convex edge shown in the figure makes it difficult for a standard tool to move the tool inward in the sink cavity to form a curved convex edge. Therefore, the processing production based on the milling forming method of the utility model can effectively improve its work efficiency, and has significant advantages in tool change efficiency, tool setting time, and processing tool time. It can also achieve rough processing, semi-finishing and finishing by adjusting the feed amount to ensure that it can process the blank from the blank to the finished product or semi-finished product, thereby achieving the purpose of improving efficiency and reducing time costs.

[0019] The specifications of the utility model are as follows: the diameter size range of the handle portion (2) is between Φ7.5mm and Φ8.5mm; the wall surface of the annular groove (30) is one of the four processed surfaces of the blade portion (3), and its molding size range is between R0.5 and R0.9; the diameter size range of the blade portion (3) at the largest point is between 12.5mm and 9.5mm, and the diameter size range of the smallest point is between 9.6mm and 10.6mm; the height size range of the blade portion (3) is between 7.5mm and 8.5mm; and the overall length size of the tool body (1) is between 26mm and 29mm.

[0020] In addition to forming special-shaped structural features in a targeted manner, the other three processing surfaces, namely the first processing surface (31), the third processing surface (33) and the fourth processing surface (34), can replace some standard tools for simple processing and finishing according to actual processing requirements, thereby saving tool changing steps and improving work efficiency.
