Abstract
The utility model discloses a kind of support of PCD end faces, including support body and composite sheet, support body is cylindrical support body, and it is provided with endoporus in cylindrical support body, one end connection shoulder hole of endoporus, the side of shoulder hole is provided with step, step is made up of vertical plane connection inclined plane, shoulder hole is interconnected with step by dismantling mouth, composite sheet includes PCD layer and cement carbide substrate, PCD layer is crimped on cement carbide substrate by high temperature, and composite sheet is welded in shoulder hole by cement carbide substrate.The utility model structural strength is big, and fixation is more stable, the supporting surface guarantee mill machining accuracy made using PCD material, and improves the quality of machined object, while composite bed can be changed, therefore support body can be recycled, and reduce entreprise cost.
Description
Technical field
The utility model is related to machine-building manufacture field, more particularly to a kind of support of PCD end faces.
Background technology
Diamond (PCD) is used to process non-ferrous metal, has well to the non-ferrous metal such as copper, aluminium, violent, gold, silver, lead, titanium
Cutting power, is widely used in automobile, motorcycle engine piston, optical instrument, motor electronic industry etc., wear-resisting non-for processing
Metal, such as hardboard, the preferable cutter material of glass transmission.At present, the existing end face support of in the market uses rectangular sheet
Shape is designed, and wear-resistant surface is prepared using cement carbide substrate, end face support structure intensity difference, the machining accuracy of rectangular patch design
It is low, and hard alloy is relative to diamond, hard alloy low intensity, wear no resistance.Therefore it is badly in need of a kind of using PCD layer conduct
Wearing layer, and the structure design of end face support can meet high intensity, the PCD end faces of high-precision process requirements are supported.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of structural strength is high, PCD layer is easily changed
PCD end faces support.
To achieve the above object, the technical solution adopted in the utility model is：A kind of PCD end faces support, including support is originally
Body and composite sheet, the support body are to be provided with endoporus, endoporus in cylindrical support body, and the cylindrical support body
One end connection shoulder hole, the side of shoulder hole is provided with step, and the step is made up of vertical plane connection inclined plane, described
Shoulder hole is interconnected with step by dismantling mouth, and the composite sheet includes PCD layer and cement carbide substrate, and PCD layer is by height
Temperature and pressure are connected on cement carbide substrate, and composite sheet is welded in shoulder hole by cement carbide substrate.
In order to further optimize above-mentioned technical proposal, the technical measures that the utility model is used also include：
Further, the other end of above-mentioned endoporus is provided with a fixing hole.
Further, the middle setting annular groove of above-mentioned cylindrical support body.
A kind of PCD end faces that the utility model is provided are supported, and its advantage is：Support body of the present utility model is adopted
With cylinder design, structural strength is big, fixed more convenient, and the supporting surface that PCD material is made ensures mill machining accuracy, and improves
The quality of machined object, while the side of shoulder hole sets dismounting mouth, when PCD layer is damaged, with crowbar from dismantling mouth by PCD layer
The composite bed for having damaged is unloaded, and replaces with new composite bed, and supports the body can to recycle, and reduces entreprise cost.
Brief description of the drawings
Fig. 1 is this practical structural representation；
Fig. 2 is top view of the present utility model；
Fig. 3 is the top view that the utility model does not install composite sheet；
Reference therein is：1-support body, 2-PCD layer, 3-cement carbide substrate, 4-vertical plane, 5-incline
Inclined-plane, 6-endoporus, 7-fixing hole, 8-annular groove, 9-shoulder hole, 10-dismounting mouth.
Specific embodiment
With reference to the accompanying drawings, technical solutions of the utility model are further described in conjunction with the embodiments, so as to preferably
Understand the utility model.
Shown in reference picture 1, Fig. 2, the utility model proposes a kind of support of PCD end faces, including support body 1 and compound
Piece, the support body is the endoporus 6 being provided with cylindrical support body, and the cylindrical support body 1, endoporus 6
One end connects shoulder hole 9, and the side of shoulder hole 9 is provided with step, and the step connects inclined plane 5 and constitutes by vertical plane 4, institute
State shoulder hole 9 to be interconnected by dismantling mouth 10 with step, the composite sheet includes PCD layer 2 and cement carbide substrate 3, PCD layer
2 are crimped on the bottom of carbide matrix 3 by high temperature, and composite sheet is welded in shoulder hole 9 by cement carbide substrate 3.
Used as a preferred embodiment, the other end of above-mentioned endoporus 6 is provided with a fixing hole 7, the bearing pin of fixing device
Insertion fixing hole is used for fixed cylinder shape and supports body.
Used as a preferred embodiment, the middle setting annular groove 8 of above-mentioned cylindrical support body 1, annular groove 8 is consolidated
Determine device and clamp further fixed cylinder shape support body, it is ensured that the precision of processing.
It is not new to this practicality although above-mentioned be described with reference to accompanying drawing to specific embodiment of the present utility model
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Various modifications or deform still in protection model of the present utility model that field technique personnel make by need not paying creative work
In enclosing.
