Abstract

The utility model relates to a combined milling cutter, which comprises two face and side cutters and a rotary handle. The two face and side cutters are assembled on the rotary handle in an interference fit manner. The blades of the two assembled face and side cutters are machined and moulded simultaneously. Two adjusting nuts are arranged on the rotary handle between the two face and side cutters and used for adjusting the machining width of the two face and side cutters. The diameter of an inner hole of the rotary handle is matched with a main shaft of a machine tool. According to the combined milling cutter, as the blades of the two face and side cutters are machined and moulded simultaneously, the jumping values of the diameter excircles and the blades of the two face and side cutters are highly consistent and both the parallelism and the height difference of step faces simultaneously machined on both sides of a part by the two face and side cutters are smaller than 0.02 mm, so that the design requirements of the part are completely met. In addition, the milling width of the cutter can be adjusted freely according to the machining requirements of the part and the consistency of the jumping values of the diameter excircles and the blades of the two face and side cutters in the whole adjusting process is not affected.

Description

A kind of combined type milling cutter
Technical field
The utility model relates to the milling cutter that machining is used, and specifically is a kind of combined type milling cutter.It is particularly suitable for the bacterial type blade root outsourcing of blade is processed, and also is suitable for other part is processed.
Background technology
The bacterial type blade root of turbine blade during fabrication; Usually all can leave allowance (seeing the A among Fig. 1) in the outsourcing of blade root; Blade is when assembling; Need replenish processing to the outsourcing of bacterial type blade root according to the actual measurement size of impeller of rotor, this replenishes processing is that outsourcing width (seeing the L ' among Fig. 1) to the bacterial type blade root carries out milling, the depth of parallelism that requires to replenish the bacterial type blade root outsourcing both sides after the completion of processing and difference of height be equal<and 0.02mm.This has proposed very high request to machining accuracy, and common process tool is difficult to directly reach this processing request, normally adopts the substep method for processing to accomplish, and this method not only working (machining) efficiency is low, and machining accuracy is also low, has directly increased the enterprise production cost.
Summary of the invention
The purpose of the utility model is: the deficiency to above-mentioned prior art, and provide a kind of machining accuracy and working (machining) efficiency all high, be particularly suitable for the combined type milling cutter that the bacterial type blade root outsourcing of blade is processed.
The technical scheme that the utility model adopts is: a kind of combined type milling cutter; Comprise two face and side cutters and a rotation handle of a knife; Said two face and side cutters are assemblied on the rotation handle of a knife with the mode of interference fit, and the blade of two face and side cutters after the assembled shapes simultaneously; On the rotation handle of a knife between two face and side cutters, be provided with two adjusting nuts, these two adjusting nuts are as the working width of regulating two face and side cutters; The diameter of bore and the machine tool chief axis of rotation handle of a knife are complementary.
Be provided with the transmission flat key between said face and side cutter and the rotation handle of a knife.
Said face and side cutter is three sword arc cutters.
The beneficial effect of the utility model is: the blade of two face and side cutters is shaped simultaneously; The diameter cylindrical of two face and side cutters and each jitter values of blade have kept the uniformity of height; The depth of parallelism of the step surface that two face and side cutters process in the part both sides simultaneously and difference of height all<0.02mm, satisfy the designing requirement of part fully; In addition, the milling width of cutter can carry out free adjustment according to the processing request of part, and whole adjustment process can not influence the diameter cylindrical of two face and side cutters and the uniformity of each jitter values of blade.It has reasonable in design, simple in structure, easy to adjust, working (machining) efficiency is high, machining accuracy is high, characteristics such as practical.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the bacterial type blade root sketch map of turbine blade.
Fig. 2 is a kind of structural representation of the utility model.
The specific embodiment
Referring to Fig. 2: the utility model comprises two face and side cutters 1 and a rotation handle of a knife 3, and endoporus 5 diameters of rotation handle of a knife 3 should be complementary with the main shaft diameter of institute use lathe.Two face and side cutters 1 are assemblied on the rotation handle of a knife 3 with the mode of interference fit; After the assembled; Simultaneously the blade of two face and side cutters 1 is processed, this has effectively guaranteed the outside diameter Φ of two face and side cutters 1 and the height uniformity of each jitter values of blade.For the driving torques that guarantee in the part processing process that two face and side cutters 1 can be enough, two face and side cutters 1 are respectively equipped with transmission flat key 4 with rotating between the handle of a knife 3.On the rotation handle of a knife 3 between two face and side cutters 1, be provided with two adjusting nuts 2, these two adjusting nuts 2 are used separately as the working width L that regulates two face and side cutters 1, and working width L can carry out free adjustment according to the processing request of part.
Above-mentioned face and side cutter 1 is three sword arc cutters.

Claims (3)

1. combined type milling cutter; Comprise two face and side cutters (1) and a rotation handle of a knife (3); It is characterized in that: said two face and side cutters (1) are assemblied on the rotation handle of a knife (3) with the mode of interference fit, and the blade of two face and side cutters (1) after the assembled shapes simultaneously; On the rotation handle of a knife (3) between two face and side cutters (1), be provided with two adjusting nuts (2), these two adjusting nuts (2) are as the working width (L) of regulating two face and side cutters (1); Endoporus (5) diameter and the machine tool chief axis of rotation handle of a knife (3) are complementary.
