Abstract

The utility model relates to a cutter head on a machine tool of a multi-plane cutting instrument, which comprises a cutter head body on which six tool holder mounting grooves are formed, wherein, the cutter head body is equally divided by the four tool holder mounting grooves which are at right angles to each other; the other two tool holder mounting grooves are symmetrically formed on the two sides of one of the four tool holder mounting grooves, and the cutter head body is equally divided by the other two tool holder mounting grooves and one of the four holder mounting grooves which are at angles of 120 DEG to each other; a tool holder mounting screw hole is formed on each tool holder mounting groove; a fixing counter bore of the cutter head and a key slot are formed on the cutter head body; tool holder counter bores and tool holder mounting screw holes are formed on tool holders; the tool holder counter bores correspond to the tool holder mounting screw holes; and the tool holders are fixed in the tool holder mounting grooves through bolts passing through the tool holder counter bores and the tool holder mounting screw holes. The tool holders and the cutter head body of the utility model are connected through the bolts, the tool holders are conveniently disassembled and assembled, and different amounts of tool holders in different positions can be mounted on the cutter head body according to the production requirements, thereby meeting the requirements for parts in flat, square, hexagonal and octagonal shapes, dispensing with operations like the customization or the change of the cutter head, and facilitating the processing of different parts.

Description

Cutterhead on a kind of many flush cuts watchmaker's machine tool

Technical field

The utility model relates to a kind of watchmaker's machine tool, relates in particular to the cutterhead on a kind of many flush cuts watchmaker's machine tool.

Background technology

Watchmaker's machine tool is a kind of equipment of common processing small-sized machine part.Common multilevel part such as the shape in flat, cubic, six sides, all directions, all is the method that adopts calibration to carry out milling, and its work efficiency is lower.Therefore if finish large batch of part production, processing has just become a very big problem.Based on this, a kind of watchmaker's machine tool of many flush cuts has appearred in the watchmaker's machine tool production industry recently, and its principle is to utilize the rotating ratio of power transmission shaft and work spindle, and diaxon rotates in the same way, finishes in the time of the many flush cut of realization workpiece.But the structure of this class lathe is all fairly simple at present, particularly aspect cutterhead, do not consider more, there is limitation in cutterhead, as shown in Figure 1, knife rest 2 ' and cutter head 1 ' are one, present cutterhead can only satisfy mostly that car is flat, cubic, six sides' needs, and can not satisfy car needs from all directions.If customer requirement car part from all directions then can only customize and change cutterhead, processing is very inconvenient.

Summary of the invention

The utility model is in order to solve the problems of the technologies described above; Provide a kind of simple in structure, need not change whole cutter head, just can realize part can car flat, cubic, the hexagon shape, the cutterhead on many flush cuts watchmaker's machine tool of part that again can car all directions shape.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises cutter head and the knife rest of being located on the cutter head, described cutter head is provided with six knife rest mounting grooves, wherein four knife rest mounting grooves are mutually branch cutter heads such as right angle, one both sides and this three knife rest mounting grooves that two other knife rest mounting groove is located in above-mentioned four knife rest mounting grooves symmetrically are mutually the described cutter head of 120 degree five equilibriums, described knife rest is located in the described knife rest mounting groove, and described cutter head is provided with cutterhead fixedly counterbore and keyway.

As preferably, described knife rest mounting groove is provided with two or more knife rests screw is installed, described knife rest is provided with knife rest counterbore and knife rest screw, it is corresponding that knife rest on described knife rest counterbore and the described cutter head is installed screw, described knife rest by pass the knife rest counterbore, knife rest is installed the bolting of screw to described cutter head.

As preferably, described cutter head and knife rest are 45 steel material.

The beneficial effects of the utility model are: knife rest links to each other by bolt with cutter head, the knife rest easy accessibility, can make up according to the needs of producing, the knife rest of varying number, diverse location is installed on cutter head, satisfy that car is flat, cubic, six sides, the needs of the part of shape from all directions, save customization or, be convenient to the processing of different parts with many work such as tool changing dishes.The utility model is made simple, and with low cost, structure is both artistic and practical.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: the cutterhead on a kind of many flush cuts watchmaker's machine tool of present embodiment, as Fig. 2, shown in Figure 3, comprise cutter head 1, have six knife rest mounting grooves 3 on the cutter head 1, wherein four knife rest mounting grooves 3 are mutually branch cutter heads 1 such as right angle, one both sides and this three knife rest mounting grooves 3 that two other knife rest mounting groove 3 is located in above-mentioned four knife rest mounting grooves 3 symmetrically are mutually branch cutter heads 1 such as 120 degree, each knife rest mounting groove 3 has three knife rests that screw 4 is installed, and cutter head 1 has cutterhead fixedly counterbore 5 and keyway 6.Have knife rest counterbore 7 and knife rest screw 8 on the knife rest 2, the knife rest on knife rest counterbore 7 and the cutter head 1 installs that screw 4 is corresponding, and knife rest 2 is embedded in the knife rest mounting groove 3, knife rest 2 by pass knife rest counterbore 7, knife rest is installed the bolting of screw 4 to cutter head 1.By knife rest screw 8 cutter is installed on the knife rest 2.Cutter head 1 and knife rest 2 adopt 45 steel material.

The utility model is carried out the mode that knife rest separates with cutter head, can knife rest be installed according to the turning situation.Following several situation is specifically arranged: after installing knife rest and cutter on any one knife rest mounting groove, the two side's shapes that come out according to multiaspect turning principle car; Load onto two knife rests and two cutters in any two relative knife rest mounting grooves, what car came out is exactly cubic shape; In orthogonal four knife rest mounting grooves, load onto four knife rests and four, the shape from all directions that car comes out cutter; In 3 knife rest mounting grooves that are mutually 120 degree, load onto three knife rests and three cutter, six side's shapes that car comes out.

It should be noted that above what enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
