Abstract
The utility model relates to a small-modulus diamond worm rod rolling wheel which comprises a worm rod rolling wheel body; the side surface of the worm rod rolling wheel body is provided with a plurality of spine-piece-shaped vapor deposition synthesized diamonds in a protruding way; and the spine-piece-shaped vapor deposition synthesized diamonds are arranged in order to form a protruded-spine-shaped circumference. The small-modulus diamond worm rod rolling wheel adopts the vapor deposition synthesized diamonds, and the vapor deposition synthesized diamonds can be cut with required shapes and sizes according to requirements, and therefore, a gear with small gear top width and a machining modulus being below M0.5 can be obtained, and the service life of the rolling wheel can be prolonged by the structure composition.
Description
Technical field
The utility model relates to Gear Processing when producing used diamond worm screw roller specifically relates to the used diamond worm screw roller of a kind of fine module gear.
Background technology
The worm abrasion wheel roll flute is a kind of process means commonly used in the Gear Processing in enormous quantities, and it is through the generating Machining of Gear on gear grinding machine with worm grinding wheel.Worm abrasion wheel used on the gear grinding machine with worm grinding wheel need obtain required shape and size through finishing, just can process qualified gear, uses diamond roller trimming now from initial being trimmed to diamond tool.
The head of worm screw roller must be than smaller by the tooth top width of the gear of grinding, guaranteeing grind whole gear profile, when the modulus of gear hour, the head of the corresponding worm screw roller very point that just becomes causes processing difficulties.
The making of diamond worm screw roller at present mainly contains 3 kinds of methods: outer plating method, interior plating method and sintering process.Outer plating method is on the outer mold surface of metallic matrix, to electroplate one deck diamond; But the head of matrix own can't be accomplished very point; Add adamantine particle diameter, therefore the diamond worm screw roller addendum width of outer plating method is not less than 0.6 (R0.3), i.e. module >=1 usually; Interior plating method is to make a former opposite with the profile of actual needs earlier; Electroplated diamond on the interior die cavity of former; Through subsequent handlings such as the demoulding, cast low-melting alloy, machineds; Obtain required diamond roller, but be subject to adamantine particle size, the tooth top width of the diamond worm screw roller that usually interior plating method is made can be not module >=0.5 less than 0.4 (R0.2) also; Sintering process is to adopt heat pressing process that diamond and bond sintering are compressed on the metallic matrix; Pass through follow-up machined and finishing again, obtain required diamond roller, be subject to adamantine particle size equally; The tooth top width of the diamond worm screw roller that sintering process is made can be not module >=0.5 less than 0.4 (R0.2) also; And in above-mentioned 3 kinds of methods,, just must select fine grain diamond for use when the tooth top width that requires during near dimension limit; This causes the life-span of diamond roller sharply to descend again, and is even not available.
The utility model content
The purpose of the utility model provides a kind of little modulus diamond worm screw roller, and used when supplying Gear Processing to produce, it can process modulus M0.5 and following gear, and the service life that can improve roller.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of little modulus diamond worm screw roller comprises the worm screw roller wheel body, on the side of worm screw roller wheel body, is extruded with the vapour deposition diamond synthesis of several spine sheet shapes, the regularly arranged formation pointed circumference of dashing forward.
Preferably, the thickness of the vapour deposition diamond synthesis of said spine sheet shape between 0.8mm-1mm, its tip width >=0.05mm.
Beneficial effect: the utility model adopts the vapour deposition diamond synthesis; Can cut into required shape and size as requested; Can obtain having very little tooth top width and processing modulus thus can be to M0.5 and following gear, the service life that such structure composition can also improve roller.

The specific embodiment
As depicted in figs. 1 and 2; A kind of little modulus diamond worm screw roller of the utility model; Comprise worm screw roller wheel body 1, on the side of worm screw roller wheel body, be extruded with the vapour deposition diamond synthesis 2 of several spine sheet shapes, the regularly arranged formation pointed circumference of dashing forward.
Be processed into the little modulus diamond of this kind worm screw roller in the following manner: process a former 3 earlier; The interior profile of former 3 is required diamond worm screw roller profile; Abrasive material adopts vapour deposition diamond synthesis 2; Vapour deposition diamond synthesis 2 is the thick sheet of 0.8mm-1mm, and the I of tip size b is cut to 0.05mm, and is as shown in Figure 3.In conjunction with shown in Figure 4, some vapour deposition diamond synthesis 2 are regularly arranged successively on the inner top of the matrix of former 3, and electroforming nickel-cobalt alloy 4 is to certain thickness in matrix; Then cooperate with iron core 5, cast low-melting alloy or glue coated make nickel-cobalt alloy 4 and iron core 5 strong bonded; The demoulding then, machining, last reconditioning vapour deposition diamond synthesis face; Obtain required size, in conjunction with Fig. 5, shown in Figure 6.
The foregoing description is technical conceive and the characteristics for the utility model is described just, its objective is to be the content that lets the one of ordinary skilled in the art can understand the utility model and to implement according to this, can not limit the protection domain of the utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the utility model.
