The utility model is a kind of thick fine boring cutter of combination for elevator box processing, the thick fine boring cutter of this combination is processed for the dead eye of elevator traction box body, it comprises the tool rest being arranged at the knife bar of back segment, the cutter hub in stage casing and leading portion, described cutter hub is evenly equipped with the some fine boring cutter grooves along its circumference, described fine boring cutter groove is arranged in the middle part of cutter hub, be provided with fine boring cutter in described fine boring cutter groove, described tool rest front end is provided with rough boring cutter.Combination of the present utility model thick fine boring cutter improves working (machining) efficiency together with being condensed to right boring two procedures by the heavy boring of elevator traction box body dead eye, reduces cooperage use, and cutter structure is simple, and reliability is high, applied widely.
Description
Technical field
The utility model relates to elevator components machining tool field, is specifically related to a kind of thick fine boring cutter of combination for elevator box processing.
Background technology
Elevator traction box body is on lathe during machining shaft bearing bore, manufacturing procedure originally first uses rough cutter (i.e. rough boring cutter) roughing hole, stay right boring surplus, and then change fine boring cutter aperture is worked into corresponding precision prescribed, it needs distribution two operations, time and production cost are very high, inefficiency.
For the problems referred to above, the heavy boring of elevator traction box body dead eye and right boring two procedures unite two into one by the utility model, and a shaft chisel completes two procedures.
Utility model content
The purpose of this utility model is to overcome prior art Problems existing, provides a kind of thick fine boring cutter of combination for elevator box processing.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of thick fine boring cutter of combination for elevator box processing, the thick fine boring cutter of this combination is processed for the dead eye of elevator traction box body, it comprises the knife bar being arranged at back segment, the cutter hub in stage casing and the tool rest of leading portion, described cutter hub is evenly equipped with the some fine boring cutter grooves along its circumference, described fine boring cutter groove is arranged in the middle part of cutter hub, fine boring cutter is provided with in described fine boring cutter groove, described fine boring cutter is spacing by cross-under alignment pin on the vertical cell wall of fine boring cutter groove, briquetting is being provided with near on the opposite side outside face of vertical cell wall relative to described fine boring cutter, described briquetting one end is against the outside face other end of fine boring cutter against the kerve face of fine boring cutter groove, and it is spacing that described briquetting screws by the kerve face of a soket head cap screw and fine boring cutter groove the triangle configuration formed fine boring cutter, described tool rest front end is provided with rough boring cutter.
Further, described cutter hub is provided with two and becomes 180 ° of fine boring cutter grooves arranged, the fine boring cutter both sides outside in fine boring cutter groove stays the seamed edge of 0.5 ㎜, and the tool orthogonal rake of described fine boring cutter gets 0 °.
Further, described rough boring cutter is fixed on tool rest by brazing.
Further, described tool rest is connected with cutter hub by contiguous block and corresponding screw.
Further, described tool rest outer face is provided with hold-down bolt and compresses tool rest and cutter hub.
The beneficial effects of the utility model are:
Together with the heavy boring of elevator traction box body dead eye is condensed to right boring two procedures by the thick fine boring cutter of combination of the present utility model, greatly improve working (machining) efficiency, reduce cooperage to use, on the basis of original two procedures, production efficiency can improve about 80%, and cutter structure is simple, and reliability is high, applied widely, all can use in the process equipment such as boring machine, machining center.
