Abstract

The present utility model relate to a diamond composite milling reamer for processing inner die cavity holes and pertains to the field of mechanical processing of cutting tools. The diamond composite milling reamer is provided with a cutter holder, the front end of the cutter holder is processed to form a drill head, the back side part of the drill head has reaming cutter teeth and molding teeth, the two sides of the cutter holder are provided with toothspaces symmetrically, and the toothspaces are installed with diamond cutter tooth respectively. The diamond composite milling reamer which has a simple structure has characteristics of completing all steps of drilling, enlarging, reaming, milling and processing of chamfer angles, geometrical shape surfaces and the like in one process, replacing multiple-station processing of lathing, boring, shaping, milling and the like on a lot of workpieces, assuring proper alignment of holes and surfaces to center lines, and preventing quality problems of low rotating precision of components, liquid or gas leakage, and the like.

Description

The diamond composite milling reamer in die cavity hole in being used to process

Technical field

The utility model relates to the machining tool field, says it is a kind of diamond composite milling reamer that is used to process interior die cavity hole in detail.

Background technology

As everyone knows: die cavity hole on auto parts and components, having a lot, die cavity hole is according to former processing technology in these, need boring, reaming, fraising, reprocess out geometry surface and chamfered part, need many operations, will change tens cutters at least and just can finish, efficient is extremely low, and each hole and surface still are difficult to guarantee to the axiality of center line, so that cause the parts running accuracy low, are easy to generate the quality problems such as leakage of liquid or gas.

Summary of the invention

The purpose of this utility model just is to overcome that existing cutter working (machining) efficiency is low, low precision and processing technology complicated technology deficiency, a kind of diamond multiple-cutting-edge compound tool that is used to process interior die cavity hole is provided, use this cutter can on a procedure, machine in the processing on brill, expansion, hinge, mill, chamfering and geometry surface etc. of die cavity, on a lot of workpiece, replaced multistation processing such as car, boring, shaping processing, mill, guaranteed each hole and surface axiality center line.

The utility model adopts following technical solution: a kind of diamond composite milling reamer that is used to process interior die cavity hole, be provided with knife bar, the front end of knife bar is processed with drill bit, the drill bit rear lateral portion is provided with reaming cutter tooth and molding gear, the bilateral symmetry of knife bar is processed with teeth groove, is separately installed with a diamond cutter tooth on the teeth groove.

The utility model also can be realized by following measure: the axial location place of knife bar is processed with tank, and tank is connected with cooling hole on the teeth groove.

The beneficial effects of the utility model are, simple in structure, the processing on brill, expansion, hinge, mill, chamfering and the geometry surface etc. of die cavity in can on a procedure, machining, on a lot of workpiece, multistation processing such as car, boring, shaping processing, mill have been replaced, guarantee each hole and surface axiality to center line, prevent to cause the parts running accuracy low, and produce the quality problems such as leakage of liquid or gas.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

1. reaming cutters tooth among the figure, 2. drill bit, 3. teeth groove, 4. tank, 5. knife bar, 6. cooling hole, 7. teeth groove, 8. cutter tooth.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding the utility model content.

As shown in Figure 1, the utility model is provided with knife bar 5, and the front end of knife bar 5 is processed with drill bit 2, drill bit 2 rear lateral portion be provided with reaming cutter tooth 1 and molding gear, the bilateral symmetry of knife bar 5 is processed with teeth groove 3 and teeth groove 7, is separately installed with a diamond cutter tooth 8 on teeth groove 3 and the teeth groove 7.All be processed with on each teeth groove and diamond cutter tooth 8 corresponding cooling holes 6, the axial location place of knife bar 5 is processed with tank 4, and tank 4 is connected with cooling hole 6 on the teeth groove, and cooling water is used for cooling, lubricates cutter through tank 4 ejection in the cooling hole 6.

Claims
