Abstract
The utility model provides a crankcase finish boring hole and under bracing face combined machining cutter, belongs to cutter technical field. It includes the cutter body, the cutter body is the step structure, and from the top down reduces in proper order, and outer bearing face blade is scraped to essence that cutter body upper portion set up interconnect and the outer bearing side tool post is scraped to the essence, and the middle part sets up and scrapes lower support face cutter, and the bottom sets up bent axle hole borer. By adopting the above technique, the utility model, it is as an organic whole with the processing collection of crankcase finish boring hole and under bracing face, obtain a novel combined machining cutter, replaced original processing cutter one to one, avoided frequent change cutter, reduce the operating procedure, the processing of bore hole, holding surface and the outer bearing face of crankcase can once only be accomplished to this combined machining cutter, improves its machining efficiency, has further improved the processingquality of crankcase moreover.
Description
Technical field
The utility model belongs to cutting-tool engineering field, is specifically related to that a kind of machine tool utilization rate is high, converted products stay-in-grade crankcase right boring hole and lower support face compound cutting tool.
Background technology
Crankcase hair needs before using to process further it, as crankshaft hole opened by needs after badly making, its lower support face needs essence to scrape, surfaces externally and internally needs chamfering etc., at present, above steps is all distributing processing, and a few procedure of score processes, and each procedure needs to use different cutters, its cutter dismounting operation is many, inefficiency, and different cutters uses and considerably increases production cost, and the Product Precision processed is unstable, product quality declines.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide that a kind of machine tool utilization rate is high, converted products stay-in-grade crankcase right boring hole and lower support face compound cutting tool.
Described a kind of crankcase right boring hole and lower support face compound cutting tool, comprise cutter body, it is characterized in that described cutter body is staircase structural model, reduce successively from top to bottom, cutter body top arranges interconnective essence and scrapes outer shaft bearing surface blade and essence scrapes outer bearing side tool post, middle part arranges and scrapes lower support surface cutter, and bottom arranges crankshaft hole borer.
Described a kind of crankcase right boring hole and lower support face compound cutting tool, scrape lower support surface cutter and comprise and scrape lower support surface surface blade and scrape lower support surface outer wall blade described in it is characterized in that.
Described a kind of crankcase right boring hole and lower support face compound cutting tool, is characterized in that the diameter of crankshaft hole borer is greater than the diameter of crankcase preformed hole.
Above-mentioned a kind of crankcase right boring hole and lower support face compound cutting tool, comprise cutter body, described cutter body is staircase structural model, reduce successively from top to bottom, cutter body top arranges interconnective essence and scrapes outer shaft bearing surface blade and essence scrapes outer bearing side tool post, middle part arranges and scrapes lower support surface cutter, and bottom arranges crankshaft hole borer.The utility model is by adopting above-mentioned technology, the processing in crankcase right boring hole and lower support face is integrated, obtain a kind of NEW TYPE OF COMPOSITE process tool, instead of original man-to-man process tool, avoid and frequently change cutter, reduce operating procedure, this compound cutting tool disposablely can complete the processing of the bore hole of crankcase, supporting surface and outer shaft bearing surface, improve its working (machining) efficiency, and further increase the crudy of crankcase.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 2-outer shaft bearing surface blade, 1-outer bearing side tool post, 3-scrapes lower support surface cutter, and 301-scrapes lower support surface surface blade, and 302-scrapes lower support surface outer wall blade, 4-crankshaft hole cutter.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited in this:
As shown in Figure 1, crankcase right boring hole of the present utility model and lower support face compound cutting tool, use for machining crankshafts case, it comprises cutter body, described cutter body is staircase structural model, reduce successively from top to bottom, cutter body top arranges interconnective essence and scrapes outer shaft bearing surface blade 2 and essence scrapes outer bearing side tool post 1, middle part arranges and scrapes lower support surface cutter 3, bottom arranges crankshaft hole borer 4, described in scrape lower support surface cutter 3 and comprise and scrape lower support surface surface blade 301 and scrape lower support surface outer wall blade 302.
The diameter of crankshaft hole borer 4 of the present utility model is greater than the diameter of crankcase preformed hole, therefore the preformed hole of crankcase essence hall can be become the hole of actual requirement.
The utility model is by adopting above-mentioned technology, this fine boring crankshaft bore, essence are scraped supporting surface and end face, essence scrapes outer shaft bearing surface, merge into a procedure, by the tandem of feed, complete fine boring crankshaft bore successively, essence scrapes supporting surface and end face, essence are scraped outer shaft bearing surface, thus completed the processing of crankcase.
Claims (2)
1. a crankcase right boring hole and lower support face compound cutting tool, comprise cutter body, it is characterized in that described cutter body is staircase structural model, reduce successively from top to bottom, cutter body top arranges interconnective essence and scrapes outer shaft bearing surface blade (2) and essence scrapes outer bearing side tool post (1), middle part arranges and scrapes lower support surface cutter (3), bottom arranges crankshaft hole borer (4), described in scrape lower support surface cutter (3) and comprise and scrape lower support surface surface blade (301) and scrape lower support surface outer wall blade (302).
