Annular groove forming turning tool complete set tool

Technical Field

The utility model belongs to the technical field of machining and discloses a complete set of tool for forming a turning tool of an annular groove.

Background

In the field of machining, a plurality of O-shaped sealing rubber ring rubber molds have high appearance requirements on a forming turning tool for machining a groove of the mold, various angles of the tool have high precision requirements, certain difficulty is caused for machining, a tool point is machined usually in a pure manual blade grinding mode, the technical level requirements of operators are strict, certain limitation is caused for the whole machining process, and the problems of low production efficiency, high rejection rate and the like are often caused due to large machining difficulty and hard tool point materials.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problems in the prior art, the utility model provides a complete set of tooling (an indexable double-shaft sliding table mechanism), as shown in fig. 2, the tooling comprises five parts: the small tool rest 5, the tool body 6, the sliding table 7, the rotating shaft 8 and the base 9.

Each part of the tool can be formed through conventional machining, the structure of the tool is used for manufacturing a base 9, a rotating shaft 8 is installed on the base through bolts in a connected mode, a sliding table 7 is moved on the outer sleeve of the rotating shaft, a fixed tool rest 5 is installed on the upper portion of the sliding table through bolts and stud pins, cutter body blanks 6 are fixed inside the tool rest through tightening bolts, then the tool is installed on a grinding machine platform through long-rod bolts, pressing plates and other tools and fixed well, and the positioning of the transverse, longitudinal, rotary and freedom degrees can be achieved. The orientation between the parts at the variable joint is fixed through a handle nut of a conventional standard part, so that the quick adjustment and positioning are realized. The whole set of tool adopts the central idea of light weight, standardization and lean, and the tool has the advantages of easy processing, low cost, convenient use and easy operation.

The specific technical scheme of the utility model is as follows: the complete set of tooling (an indexable double-shaft sliding table mechanism) is fixed on a tool grinding machine platform, and the postures of the transverse direction and the rotating shaft on the sliding table are adjusted, so that the forming turning tool body clamped on the tool rest and the cup-shaped grinding wheel form a proper feeding angle. And (the cup-shaped grinding wheel needs to be trimmed to form a required inclination angle in advance according to grinding parameters) the mechanical manufacturing of the annular groove forming turning tool is finally realized through repeated certification in a production field.

The tool has the advantages that the tool point of the tool can be quickly centered, positioned and stably clamped only by arranging the self-made complete tool (the indexable double-shaft sliding table mechanism) with a simple structure on the universal tool grinding machine, and the tool is simple in structure, low in cost, convenient to operate, simple to maintain and suitable for conventional machining. Professional training of operators is not needed, and difficulty is low. The problem that a forming turning tool of a ring groove in an O-shaped sealing rubber ring die is not easy to grind is effectively solved. The technical bottleneck is broken for many years, the machining precision of the cutter is ensured, and the utility model has the characteristics of low production cost and high production efficiency and has wide application prospect. The tool point machining device is suitable for machining the tool point of the annular groove forming turning tool on a conventional grinding machine in cooperation with a special tool clamp, can realize quick centering and original point reference setting, replaces the traditional method of an operator, makes up the blank of mechanical machining of the tool point of the forming turning tool, and has general significance for the fields of aviation and even mechanical machining.

Detailed Description

1, installing a complete set of tooling:

as shown in fig. 2. The small tool rest 5, the sliding table 7, the rotating shaft 8 and the base 9 are assembled and formed into a complete set of tool according to a drawing, the rotating shaft is installed on the base through bolts in a connected mode, the sliding table is sleeved between the rotating shafts, the upper portion of the sliding table is fixedly installed on the tool rest through bolts and stud pins, cutter body blanks are fixed inside the tool rest through tightening bolts, then the tool is installed on a grinding machine platform through long rod bolts, pressing plates and other tools and fixed well, and positioning of transverse, longitudinal, rotating and freedom degrees can be achieved. The orientation between the parts at the variable joint is fixed through a handle nut of a conventional standard part, so that the quick adjustment and positioning are realized.

2, tool machining, mounting and positioning:

as shown in fig. 1, namely, the clamping mode of the annular groove forming turning tool. Firstly, a cup-shaped grinding wheel 3 is arranged on a universal tool grinding machine 2, if the axis of the grinding wheel is upwards raised by 10 degrees, 10 degrees are the back angle of a cutter, then a complete set of tooling (an indexable double-shaft sliding table mechanism) 1 is arranged on a grinding machine platform 4 and is fixed to the platform through a base 9; as shown in fig. 2, the ground turning tool body 6 is fixed in the small tool holder 5. Finally, the cup mouth of the cup-shaped grinding wheel 3 is trimmed and polished into a sharp point less than 90 degrees, and the sharp point is the working part of the grinding wheel.

3, forming and processing of a cutter:

as shown in fig. 2, a tool body blank 6 to be processed is mounted in a small tool rest 5, and then integrally fixed to a general tool grinding machine 2 together with a tool set 1, the postures of two axes of a sliding table 7 and a rotating shaft 8 are adjusted to enable the circular arc center of a tool tip of the tool body 6 to be coaxial with the rotating shaft 8, then the sharp point of a cup-shaped grinding wheel 3 is adjusted to be consistent with the tool center, and the grinding diameter of the tool can be controlled through the feeding amount of the grinding wheel, so that the precise grinding of the tool inclination angle and the tool neck is realized. As shown in fig. 3, the flank 10 after grinding forms a tool relief angle, and the rotating shaft 8 is required to rotate by 190 degrees continuously during grinding to form the whole flank, and the cup wheel 3 keeps a fixed elevation angle of 10 degrees.

As shown in figure 4, the processing method is ingenious in that the small tool rest 5 of the tool set can smoothly enter the interior of the cup-shaped grinding wheel in the rotating process, and does not interfere with other parts of the grinding wheel. (the cup-shaped grinding wheel is used for grinding the turning tool angle in a special matching way, and the grinding of the tool cannot be realized if the grinding wheel with other shapes is adopted).
