Abstract
The invention discloses a kind of support components and its manufacturing method for outdoor measuring instrument, the support member includes having the front end position of higher hardness and with the rear end position compared with soft, the volume at the front end position is greater than the volume at the rear end position, and the surface at the rear end position is coated with chrome layer.The present invention is protected by chrome layer, is handled the position for needing to improve hardness to the property of can choose, without changing by the hardness of chrome layer protection portion position, simultaneously because product surface is covered with one layer of chrome layer, can play the role of preventing from getting rusty.
Description
Technical field
The application belongs to the bracing reinforcement field of measuring instrument, more particularly to one kind for often in outdoor adverse circumstances
The support member and its manufacturing method of the instrument of surveying and mapping of middle work.
Background technique
For measuring instrument in field work, environment is extremely severe, and the time, which has been grown, to be easy to cause fracture or get rusty.
In the prior art, measuring instrument support member is processed into after product using bearing steel and is improved with the technique of quenching
Then hardness grinds critical size position again, it is the same for will lead to product hardness of entire workpiece after integral quenching in this way
, cause the toughness of workpiece not good enough, and measuring instrument is more accurate, needs certain drop resistant ability, field wind and rain is more,
Certain antirust ability is needed, existing product and technique can not meet these requirements.
Summary of the invention
To solve the above problems, the purpose of the present invention is to provide a kind of support components for outdoor measuring instrument
And its manufacturing method, to overcome deficiency in the prior art.
To achieve the above object, the invention provides the following technical scheme:
A kind of support member for instrument of surveying and mapping, including the front end position with higher hardness and with compared with soft
Rear end position, the volume at the front end position are greater than the volume at the rear end position, and the surface at the rear end position is coated with chromium plating
Layer.
Preferably, the material of the support member is steel alloy.
Correspondingly, disclosed herein as well is a kind of manufacturing methods of support member for instrument of surveying and mapping, including
(1), alloy steel is handled by quenched thermal process；
(2), to treated, steel alloy carries out being processed into support member semi-finished product；
(3), in surface of semi-finished chromium plating；
(4), the chrome layer on the portion faces of front end is removed.
Compared with the prior art, the advantages of the present invention are as follows: the present invention to be protected by chrome layer, the property of can choose to needing
The position for improving hardness is handled, without changing by the hardness of chrome layer protection portion position, simultaneously because product surface covers
It is stamped one layer of chrome layer, can play the role of preventing from getting rusty.
Specific embodiment
The embodiment of the present application discloses a kind of support member for instrument of surveying and mapping, including the front end with higher hardness
Position and with the rear end position compared with soft, higher hardness is greater than compared with soft, and the surface at rear end position is coated with chrome layer.
Further, the material of support member is steel alloy.
The embodiment of the present application also discloses a kind of manufacturing method of support member for instrument of surveying and mapping, comprising:
(1), alloy steel is handled by quenched thermal process；
(2), to treated, steel alloy carries out being processed into support member semi-finished product；
(3), in surface of semi-finished chromium plating；
(4), the chrome layer on the portion faces of front end is removed.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, this field ordinary engineering and technical personnel is to the technology of the present invention side
The various changes and improvements that case is made, should fall within the scope of protection determined by the claims of the present invention.
Claims (2)
