Abstract
This application discloses a kind of rotatable parts for instrument of surveying and mapping and its manufacture method, this rotatable parts includes the first position with the first hardness and the second position with the second hardness, described first hardness is more than described second hardness, and the surface of described second position is coated with nickel dam.The present invention is protected by nickel dam, can optionally the position needing to improve hardness be processed, and without changing the hardness being protected position by nickel dam, simultaneously because product surface is coated with one layer of nickel dam, can play the effect preventing from getting rusty.
Description
Technical field
The application belongs to survey field, more particularly to a kind of rotation section for instrument of surveying and mappings such as total powerstation, level gauges
Part and its manufacture method.
Background technology
In prior art, rotatable parts use and are arrived with the technique raising hardness of quenching after bearing steel is processed into product
65 ° about, then grind critical size position again, such product has a drawback it is simply that product is after integral quenching
, all at 65 ° about, the toughness of such workpiece is not just good enough for the hardness of whole workpiece because the use particularity of instrument of surveying and mapping it is desirable to
There is certain drop resistant ability.Also have and be just because that the use environment major part of the instrument of surveying and mappings such as total powerstation is more severe, so
The antirust ability of part is had high demands, but does not allow to apply antirust oil, so method before adds when completed knocked down products again
Work product out is also not ideal on antirust.
Content of the invention
It is an object of the invention to provide a kind of rotatable parts for instrument of surveying and mapping and its manufacture method, existing to overcome
Deficiency in technology.
For achieving the above object, the present invention provides following technical scheme：
The embodiment of the present application discloses a kind of rotatable parts for instrument of surveying and mapping, including having first of the first hardness
Position and the second position with the second hardness, described first hardness is more than described second hardness, the plated surface of described second position
There is nickel dam.
Preferably, above-mentioned for, in the rotatable parts of instrument of surveying and mapping, described first hardness is HRC65 °～70 °.
Preferably, above-mentioned for, in the rotatable parts of instrument of surveying and mapping, described second hardness is HRC20 °～30 °.
Preferably, above-mentioned in the rotatable parts of instrument of surveying and mapping, the thickness of described nickel dam be 0.01mm～
0.02mm.
Preferably, above-mentioned for, in the rotatable parts of instrument of surveying and mapping, the material of described rotatable parts is 38CrMoAl
Steel alloy.
Correspondingly, disclosed herein as well is a kind of manufacture method of the rotatable parts for instrument of surveying and mapping, including：
(1), 38CrMoAl steel alloy material is processed through quenched thermal process；
(2), the steel alloy after processing is processed making rotatable parts semi-finished product；
(3), in surface of semi-finished nickel plating；
(4), remove the nickel dam on first position surface；
(5), nitridation process is adopted to improve the hardness of first position.
Compared with prior art, it is an advantage of the current invention that：The present invention is protected by nickel dam, can be optionally to needs
The position improving hardness is processed, without changing the hardness being protected position by nickel dam, simultaneously because product surface is coated with
One layer of nickel dam, can play the effect preventing from getting rusty.
Specific embodiment
The embodiment of the present application discloses a kind of rotatable parts for instrument of surveying and mapping, including having first of the first hardness
Position and the second position with the second hardness, the first hardness is more than the second hardness, and the surface of second position is coated with nickel dam.
In this technical scheme, rotatable parts can apply to the instrument of surveying and mappings such as total powerstation, level gauge.In the present embodiment only
Energy nickel plating, as antirust coat, can not accomplish the nitriding of selectivity position using doing below if other material during nitridation process again,
Occur that whole workpiece all can nitriding.
Further, the first hardness is HRC65 °～70 °.More preferably 70 °.
In this technical scheme, when doing fatigue test, (2000 revs/min of rotating speed is continuous to rotate 170 to high rigidity
Hour) the no any damage in surface.
Further, the second hardness is HRC20 °～30 °.More preferably 30 °.
In this technical scheme, soft position has enough toughness, when meeting and beat collision is not in
The phenomenons such as rupture.
Further, the thickness of nickel dam is 0.01mm～0.02mm.
In this technical scheme, protected by nickel dam, accordingly even when long storage time, work is not yet under rugged environment
Get rusty phenomenon occurs.
Further, the material of rotatable parts is 38CrMoAl steel alloy.
The embodiment of the present application also discloses a kind of manufacture method of the rotatable parts for instrument of surveying and mapping, including：
(1), 38CrMoAl steel alloy material is processed through quenched thermal process；
(2), the steel alloy after processing is processed making rotatable parts semi-finished product；
(3), in surface of semi-finished nickel plating；
(4), remove the nickel dam on first position surface；
(5), nitridation process is adopted to improve the hardness of first position.
In this technical scheme, apply 38CrMoAl steel alloy material, first pass through quenched thermal process and process, it can make it
Metal properties are stable, are also beneficial to follow-up nitridation process.
It should be noted that herein, such as first and second or the like relational terms are used merely to a reality
Body or operation are made a distinction with another entity or operation, and not necessarily require or imply these entities or deposit between operating
In any this actual relation or order.And, term " inclusion ", "comprising" or its any other variant are intended to
Comprising of nonexcludability, wants so that including a series of process of key elements, method, article or equipment and not only including those
Element, but also include other key elements being not expressly set out, or also include for this process, method, article or equipment
Intrinsic key element.In the absence of more restrictions, the key element that limited by sentence "including a ..." it is not excluded that
Also there is other identical element including in the process of key element, method, article or equipment.
The above is only the specific embodiment of the application it is noted that coming for those skilled in the art
Say, on the premise of without departing from the application principle, some improvements and modifications can also be made, these improvements and modifications also should be regarded as
The protection domain of the application.
