Abstract
The invention relates to a tool special for bearing appearance quality inspection and a using method. The problem that determination performed on surface defects such as scratches, nicks and sink marks through visual inspection in the prior art is poor in operability is solved. The tool special for bearing appearance quality inspection is composed of a pen point, a pen holder and a locking nut. The pen point is composed of a screw rod section, a middle connecting rod and a ruby nib; the ruby nib is arranged at the end of the pen point and connected with the screw rod section through the middle connecting rod; the pen holder is of a hollow structure, the two ends of the pen holder are provided with internal threads, and the screw rod section is matched with the internal thread at one end of the pen holder. The method comprises the steps that under the floodlight irradiation condition, the pen point perpendicularly makes contact with the surface of a bearing part to be inspected, and then pressure is exerted to the pen holder to enable the pen holder to slide on the surface of the bearing part to be inspected; when the pen point is clamped, it is indicated that the standard requirement is not met. The tool is used for appearance quality inspection of finished bearings and finished parts.
Description
Technical field
The present invention relates to a kind of special bearing presentation quality checking tool and using method.
Background technology
At present, bearing and its spare part in process of production, in order to improve the ex factory pass rate of product, need to be to product appearance
Whether quality is qualified to be checked, for the decision problem of the depth acceptable degree of the defects such as scuffing, indentation and indenture, need to carry
For a kind of simple, quick, workable inspection method.
External aircraft bearing presentation quality test stone is carried out to surface defect using special detection tool in a standard
Identification, and detailed regulation has been carried out to the using method of instrument, enhance the practicality of standard.Domestic standard Main Basiss
GJB269-87《Aviation rolling bearing technical conditions》In technical requirements to bearing outward appearance, content is fairly simple, and to scratching,
The judgement that the surface defect such as indentation and indenture is visually inspected does not have operability.
Content of the invention
The present invention is that do not have to solve the existing judgement that the surface defects such as scuffing, indentation and indenture are visually inspected
The problem of operability, and a kind of special bearing presentation quality checking tool and using method are provided.
A kind of special bearing presentation quality checking tool of the present invention is made up of nib, penholder and locking nut；Described pen
Head is made up of spiro rod section, middle part connecting rod and ruby nib；Described ruby nib is arranged on the end of nib, described red treasured
Slate pencil point is connected with spiro rod section by middle part connecting rod；For hollow structure and two ends are provided with internal thread to described penholder, described spiral shell
Bar segment is matched with the internal thread of penholder one end, and the outside that described spiro rod section is connected with the internal thread of penholder one end is provided with locking
Nut.
A kind of special bearing presentation quality checking tool is carried out according to the following steps：
Under the conditions of astigmatism light irradiation, using special bearing presentation quality checking tool, bearing part to be measured is checked,
By nib perpendicular to bearing part surface to be measured, ruby nib is contacted with bearing part surface to be measured, then applies pressure to penholder
Enter line slip on bearing part surface to be measured, when catching phenomenon in nib, illustrate that it is not inconsistent standardization requirement.
Beneficial effect：
The present invention can accurately judge presentation quality, application specific bearing presentation quality checking tool, facilitates reviewer to grasp
Make, the judgement to defects such as bearing surface scuffing, indentation and indentures is more directly perceived, increased the operability of standard.The present invention uses
Presentation quality inspection in bearing finished products and fabricated part.
Brief description
Fig. 1 is a kind of structural representation of special bearing presentation quality checking tool.
Specific embodiment
Specific embodiment one：In conjunction with Fig. 1, present embodiment is described, a kind of present embodiment special bearing presentation quality is examined
