Abstract
The utility model discloses a PCD (polycrystalline diamond) reamer for machining a positioning hole of a valve body of a trailer of a motor vehicle, comprising a reamer body and a reamer head, wherein the front end of the reamer head is provided with a cutting edge; and the front reamer surface of the reamer head is a helical surface. The front surface of the reamer head is a helical surface, therefore, scrap discharging is convenient, the cutting force can be effectively reduced, the service life of the reamer is prolonged, simultaneously, the machining accuracy of the cutting is also greatly improved, and the quality of workpieces are greatly improved.
Description
Technical field
The utility model belongs to the machining tool technical field, particularly a kind of PCD reamer that is used for processing automobile trailer valve body locating hole.
Background technology
Along with development of science and technology, machinery manufacturing industry also is more and more higher to the requirement of machining accuracy, adopts the PCD reamer as the processing of auto trailer valve body locating hole, and the PCD reamer can directly influence the machining accuracy of machine-building.At present, PCD reamer cutting edge mainly is composite polycrystal-diamond (or polycrystalline cubic boron nitride composite sheet), this composite sheet is formed through the HTHP compacting by polycrystalline diamond layer (or polycrystalline cubic boron nitride layer) and hard alloy layer, and composite sheet is in the same place by solder bond with cutter hub.Because the rake face of this kind reamer is the plane, causes reamer in cutting process, the chip removal difficulty, cutting force is bigger, and machining accuracy is low, and working (machining) efficiency is low, and reamer is short service life.
The utility model content
The purpose of this utility model provides a kind of chip removal, PCD reamer that is used for processing automobile trailer valve body locating hole that cutting force is little be convenient to.
For achieving the above object, the technical solution of the utility model is: a kind of PCD reamer that is used for processing automobile trailer valve body locating hole, comprise cutter hub and cutter head, and the cutter head front end is provided with cutting edge, and the rake face of described cutter head is a helicoid.
Described cutter hub and cutter head core are provided with water injection hole, and helicoid is provided with the apopore that communicates with water injection hole.
Described water injection hole is provided with the apopore that leads to cutting edge near the end of cutting edge.
The rake face of the utility model cutter head is a helicoid, is convenient to chip removal, and can effectively reduce cutting force, prolongs cutter life; Simultaneously, the precision of machining is greatly enhanced, the workpiece quality also greatly promotes.
Be provided with the apopore that communicates with water injection hole on helicoid, water injection hole is provided with the apopore that leads to cutting edge near an end of cutting edge, and the temperature when being beneficial to chip removal and reducing cutting guarantees that machining carries out smoothly.
The utility model is simple in structure, reasonable in design, can improve the machining accuracy of workpiece, increases the service life, and improves working (machining) efficiency, strengthens product competitiveness.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
The PCD reamer that is used for processing automobile trailer valve body locating hole as depicted in figs. 1 and 2, it comprises cutter hub 1 and cutter head 2, and cutter head 2 front ends are provided with cutting edge 5, and cutter hub 1 is provided with water injection hole 3 with cutter head 2 cores.Cutting edge 5 mainly is polycrystalline diamond (PCD) composite sheet (or polycrystalline cubic boron nitride composite sheet), this composite sheet is suppressed through HTHP by polycrystalline diamond (PCD) layer (or polycrystalline cubic boron nitride layer) and hard alloy layer and is formed, and composite sheet and cutter hub 1 are in the same place by solder bond.The rake face of cutter head 2 is a helicoid 6, is convenient to chip removal, and can effectively reduce cutting force, prolongs cutter life; Be provided with the apopore 4 that communicates with water injection hole 3 on helicoid 6, water injection hole 3 is provided with the apopore 7 that leads to cutting edge 5 near an end of cutting edges 5, and the temperature when being beneficial to chip removal and reducing cutting guarantees that machining carries out smoothly.
The utility model is specially adapted to processing automobile trailer valve body locating hole, is convenient to chip removal, and cutting force is little, machining accuracy height, working (machining) efficiency height, the prolongation of looking cutter life.
