Abstract
The invention discloses a kind of three line value detecting tools, including common normal micrometer, retainer and needle roller, described retainer is respectively arranged at common normal micrometer two and measures on the work surface of end；The dovetail groove identical with common normal micrometer it is provided with on described retainer；Being provided with opening on this retainer, described needle roller inserts retainer from one end, and blocks opening with elastic u-shaped catch；Make needle roller can not come off from retainer, during measurement, it is positioned in the retainer of common normal micrometer stationary face two needle rollers of loading, needle roller is made to slide into the working channel of screw rod to be measured, it is positioned in the retainer of common normal micrometer motion work surface one needle roller of loading, also needle roller is slided into the working channel of screw rod to be measured, measures according to the operation principle of micrometer, three line values of screw rod can be drawn.The present invention has simple and quick, reduces processing cost, reduces the measurement time, improves work efficiency, be widely used, the advantage that needle roller does not falls off in retainer.
Description
Technical field
The invention belongs to detecting tool technical field, especially relate to a kind of three lines being applicable to screw rod processing
Value detecting tool.
Background technology
At work, steel ball contacts ball screw pair with screw rod working channel, forms rolling friction, its
The way of contact is Gothicism curvilinear contact；In the screw rod course of processing, especially roller pricks screw rod, Yin Qijia
The size being i.e. commonly called as, easily occurs that screw rod is inconsistent at the working channel of diverse location, in the restriction of work technique
Head, therefore, in the inspection during manufacture of screw rod, needs the situation checking screw rod concentric reducer whether occur, mesh
Before, usual way is that standard nut coordinates with screw rod, runs to the other end from screw rod one end, checks spiral shell
Female walking smooth degree, but for the ball screw produced in enormous quantities, this method of inspection is the most numerous and diverse；In fact,
Practice examining has only to measure steel ball coordinate with screw channel after center of circle diameter, i.e. three line values, just
Whether can there is concentric reducer by simple and fast inspection screw rod, but because diameter of the steel ball is too small, it has not been convenient to measure, and
Use the needle roller identical with diameter of the steel ball as simulation steel ball uses, and with common normal micrometer measurement
Words, can not fix because of needle roller in measurement, still measurement are caused very big inconvenience, reduce work efficiency.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of simple and quick, reduces processing cost, reduces and survey
The amount time, improving work efficiency, be widely used, needle roller does not falls off in three line value detecting tools of retainer.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of three line value detecting tools,
Including common normal micrometer, retainer and needle roller, described retainer is respectively arranged at common normal micrometer two
On the work surface of individual measurement end, and less than common normal micrometer work surface；Be provided with on described retainer with
The dovetail groove that common normal micrometer is identical；Being provided with opening on this retainer, described needle roller inserts from one end
Retainer, and block opening with elastic u-shaped catch.
The described retainer being positioned at common normal micrometer stationary face is provided with two needle rollers.
The described retainer being positioned at common normal micrometer motion work surface is provided with a needle roller.
Owing to using technique scheme, traditional measurement can not be fixed because of needle roller, measurement is caused greatly
Inconvenience, so, the present invention makes special retainer, make needle roller in the range of retainer slidably, with
It is convenient for measuring；Retainer is designed as lower section the dovetail groove identical with common normal micrometer, is installed on public law
On the work surface at line micrometer two ends, and less than common normal micrometer work surface, needle roller uses from one end
Insert the form of retainer, and block opening with resilient U-shaped catch, make the needle roller can not be from retainer
In come off, during measurement, be positioned in the retainer of common normal micrometer stationary face loading two needle rollers,
Make needle roller slide into the working channel of screw rod to be measured, be positioned in the retainer of common normal micrometer motion work surface
Load a needle roller, also needle roller is slided into the working channel of screw rod to be measured, according to the operation principle of micrometer
Measure, three line values of screw rod can be drawn, same screw rod is carried out the multipoint measurement of multi-angle,
Measurement of comparison numerical value, the three line value curves going out screw rod, thus and screw rod required precision curve comparison,
And then the machining accuracy of detection screw rod.
The invention has the beneficial effects as follows: have simple and quick, when reducing processing cost, reduction measurement
Between, improving work efficiency, be widely used, needle roller does not falls off in retainer advantage.
Accompanying drawing explanation
Below with reference to accompanying drawing and combine example and be specifically described the present invention, advantages of the present invention and realization
Mode will become apparent from, and wherein content shown in accompanying drawing is only used for explanation of the present invention, and not structure
The restriction gone up in all senses of the present invention in pairs, in the accompanying drawings:
Fig. 1 is the structural representation of the present invention
In figure:
1, common normal micrometer 2, screw rod to be measured 3, retainer
4, needle roller 5, screw rod working channel 6, opening
7, elastic u-shaped catch
Detailed description of the invention
As it is shown in figure 1, a kind of three line value detecting tools of the present invention, including common normal micrometer 1, keep
Frame 3 and needle roller 4, described retainer 3 is respectively arranged at common normal micrometer 1 two and measures the work of end
On face, and less than common normal micrometer 1 work surface；It is provided with on described retainer 3 and common normal thousand points
The dovetail groove that chi 1 is identical；Being provided with opening 6 on this retainer 3, described needle roller 4 inserts from one end and protects
Hold frame 3, and block opening 6 with elastic u-shaped catch 7；Described it is positioned at common normal micrometer 1 regular worker
Make the retainer 3 in face is provided with two needle rollers 4；Described it is positioned at common normal micrometer 1 motion work surface
Retainer 3 in a needle roller 4 is installed.
The work process of this example: during measurement, is positioned at the retainer of common normal micrometer 1 stationary face
Load two needle rollers 4 in 3, make needle roller 4 slide into the screw rod working channel 5 of screw rod 2 to be measured, be positioned at public law
The retainer 3 of line micrometer 1 motion work surface loads a needle roller 4, also needle roller 4 is slided into be measured
The screw rod working channel 5 of screw rod 2, measures according to the operation principle plesiotype of micrometer, can draw to be measured
Three line values of screw rod 2, carry out the multipoint measurement of multi-angle, measurement of comparison to same screw rod 2 to be measured
Numerical value, the three line value curves going out screw rod 2 to be measured, thus and screw rod 2 required precision curve to be measured
Contrast, and then detect the machining accuracy of screw rod 2 to be measured.
Above embodiments of the invention are described in detail, but described content has been only the preferable of the present invention
Embodiment, it is impossible to be considered the practical range for limiting the present invention.All according to the scope of the invention made equal
Deng change and improvement etc., within all should still belonging to this patent covering scope.
