Abstract
The utility model relates to a compound cutter for cylindrical cover guide pipe holes and seat ring holes. The compound cutter can process the guide pipe holes and the seat ring holes at one step and comprises a cutter, and a cutting edge, a squeezing edge, a guiding edge and a seat ring hole and boring hole cutter in the compound cutter are successively located on a cutter arbor from front to back. The compound cutter has the advantages that firstly, production efficiency is increased by 10%, processing precision (concentricity is within 0.02, and perpendicularity is within 0.05) is ensured, and quality goods ratio is increased by 2%, secondly, the compound cutter adopts a design of squeezing after reaming in terms of processing, and effectively guarantees durability of the cutter and roughness of processed surfaces, and thirdly, processing costs of products are reduced.
Description
Technical field
The utility model relates to disposable a kind of cylinder head guide pipe hole, the compound cutter in seat ring hole that guide hole and seat ring hole are processed of the enough compound cuttves of a kind of energy, belongs to cutter and makes the field.
Background technology
Separate machined when existing cylinder cover guide hole and seat ring hole, the processes sequential system is: guide hole: 1. bore ￠ 14 bottom outlets, 2 heavy borings are to ￠ 15.5, and 3. right boring is to ￠ 15.8, with the extruding cutter be squeezed to ￠ 16 (+0.025/+0) size, each needs one cutter each road preface; The seat ring hole: 1. heavy boring seat ring hole bottom outlet is to ￠ 52, and 2. half right boring is to ￠ 52.8, and 3. right boring is to ￠ 53(+0.03/0) each road preface each need one cutter.Its weak point: this processing technology because of cutter changing often, length not only consuming time, and guide hole and seat ring hole be not disposable processing, causes that easily axiality is overproof.
The utility model content
Purpose of design: avoid the weak point in the background technology, design disposable a kind of cylinder head guide pipe hole, the compound cutter in seat ring hole that guide hole and seat ring hole are processed of the enough compound cuttves of a kind of energy.
Design: in order to realize above-mentioned purpose of design.To be used to process the Tool Design that is used to process guide hole and seat ring hole is one, and once guide hole and seat ring hole time processing is gone out.Its technical scheme: a kind of cylinder head guide pipe hole, the compound cutter in seat ring hole, it comprises cutter, the cutting edge in the described compound cutter, extruding sword, guiding sword, seat ring hole hole boring cutter are positioned on the knife bar from front to back successively.
The utility model is compared with background technology, and the one, production efficiency has improved 10%, has guaranteed machining accuracy (in the axiality 0.02, in the perpendicularity 0.05), and the percentage of A-class goods has improved 2%; The 2nd, because the first design of afterwards squeezing of cutting with scissors has been adopted in the processing of compound cutter, effectively guaranteed the roughness of tool life and machined surface; The 3rd, reduced the product processing cost.

The specific embodiment
Embodiment 1: with reference to accompanying drawing 1-5.A kind of cylinder head guide pipe hole, the compound cutter in seat ring hole, it comprises cutter, the cutting edge 1 in the described compound cutter, extruding sword 2, guiding sword 3, seat ring hole hole boring cutter 5 are positioned on the knife bar 4 from front to back successively.
Described cutting edge 1, extruding sword 2, guiding sword 3 closely touch successively mutually.
Described cutting edge 1 is made of six cutter head equidistant ring, cutting edge 2 inclination angle angles 8 degree.
Described extruding sword 2 is made of six cutter head equidistant ring, extruding sword 2 inclination angle angles 15 degree.
Described guiding sword 3 is made of six cutter head equidistant ring, guiding sword 3 inclination angle angles 15 degree.
Described seat ring hole hole boring cutter 5 is made of six cutter head equidistant ring, seat ring hole hole boring cutter 5 inclination angle angles 10 degree.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
