Abstract
A method of middle-size and small-size bearing no marking fulcrum is improved, bearing machining is related to.In order to which fulcrum trace occurs and need to add a procedure removing trace when solving the problem of to the processing of bearing outer ring mill, superfinishing outer rollaway nest.Coat side is covered on alloy block, and supporting point body and alloy block not will produce cut when being contacted with coat side by welding integrator, workpiece, the process that can remove reconditioning outer diameter, while the service life that increases fulcrum itself, reduces production cost.
Description
Technical field
The technical program belongs to bearing machining field.
Background technology
The material of country's bearing industry bearing outer ring mill processing fulcrum is substantially alloy at present, can during processing
Fulcrum trace is generated on outer ring, it is necessary to fulcrum trace be removed by reconditioning outer diameter, one procedure of addition is thus needed to make a return journey
Except trace, not only increases the production cycle and also improve production cost.
Technical solution content
The purpose of the technical program be in order to solve the problems, such as the production cycle increase the production cost increases this, and then provide one
The method that kind improves middle-size and small-size bearing no marking fulcrum.
The technical program plan uses novel fulcrum, and fulcrum is made of 3 parts, including supporting point body, alloy block, coat side,
Supporting point body 45# materials are alloy block with the material that supporting point body is combined, and the two is combined and completed by vacuum silver soldering, last
A part of coat side is PVD materials, and PVD is combined with alloy block by physical vapour deposition (PVD).(physical vapour deposition (PVD),
In vacuum, low-voltage makes plating material evaporate under high current effect, and molecule or ion generate a variety of reactions after collision, molecule or
Ion is in substrate deposit.)
The technical program has the following effects that compared with prior art：When workpieces processing, workpiece is in contact not with supporting point body
Cut is will produce, while supporting point body service life increases.
Description of the drawings
Fig. 1 is schematic diagram before the middle-size and small-size bearing no marking fulcrum described in the technical program improves；
Fig. 2 is schematic diagram after the middle-size and small-size bearing no marking fulcrum described in the technical program improves；
Specific implementation mode
In order to make the object, technical solution and advantage of the technical program be more clearly understood, below in conjunction with attached drawing to this skill
Art scheme is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain this technology side
Case is not used to limit the technical program.
Specific implementation mode one illustrates the technical program embodiment referring to Figures 1 and 2, described in present embodiment
A method of improving middle-size and small-size bearing no marking fulcrum, which is characterized in that include the following steps：
Step 1：We plan the novel fulcrum used, and fulcrum includes supporting point body, alloy block, coat side；
Step 2：Supporting point body selects 45# materials, is alloy block with the material that supporting point body is combined, the two passes through vacuum silver
It is soldered into.
Step 3：The material selection of coat side is PVD materials, and PVD is covered on alloy block, and the two is heavy by physical vapor
Product combines.
Step 4：Whether there is cut to test at fulcrum by using new material coat side, fulcrum is not external
Diameter generates bearing trace.
Specific implementation mode two, the method according to specific implementation mode one, it is characterised in that step 3 floating coat face
Selected material is PVD materials, and PVD is covered alloy block surface；
Specific method is：When using PVD covering alloy blocks, chooses workpiece and covered with the surface that supporting point body easily contacts.
Specific implementation mode three, the method according to specific implementation mode one, it is characterised in that PVD is covered in step 3
Onto alloy block, the two is combined by physical vapor deposition；
Specific method is：In a vacuum, low-voltage makes plating material evaporate under high current effect, and molecule or ion are by collision
After generate a variety of reactions, molecule or ion are in substrate deposit.
In the description of the technical program, it should be noted that unless otherwise clearly defined and limited, term " knot
Conjunction ", shall be understood in a broad sense " covering ", for example, it may be being fixedly connected, be integrally connected；Can be that partial mulching or entirety are covered
Lid；For the ordinary skill in the art, above-mentioned term in the technical scheme specific can be understood with concrete condition
Meaning.
The foregoing is merely the preferred embodiments of the technical program, all at this not to limit the technical program
All any modification, equivalent and improvement etc., should be included in the technical program made by within the spirit and principle of technical solution
Protection domain within.
