Description
Technical Field
The utility model relates to a detect frock, especially a ball valve spheroid circularity short-term test frock.
Background
The schematic diagram of a currently-used sphere inspection tool is shown in fig. 1, after a sphere is placed and fixed, a micrometer is used for measuring two points at any diameter on the sphere, measuring points are randomly selected, and data obtained through measurement are analyzed to judge the actual processing roundness of the sphere.
According to the tool for detecting the roundness of the sphere, the diameter of the sphere needs to be measured once when each datum is obtained, the roundness of the sphere needs to be accurately obtained, the diameter of the sphere needs to be measured for many times, and the more measurement points, the more the reflected roundness is, the more accurate the roundness is. Meanwhile, in the whole sphere roundness detection process, the measured diameter occupies most of time, more time is needed for repeated measurement, and the selected measuring points are random and more in one surface, so that the accuracy of the sphere roundness cannot be better reflected. Especially when the spheroid is great in batches, bring inconvenience for the inspection work after the spheroid processing, and the commonality of micrometer as the inspection tool is not good, and the spheroid of different bores need select the micrometer of corresponding specification for use just can measure. Therefore, a tool is designed, the variable quantity of the roundness of the ball can be quickly and accurately detected, the structure is compact, the tool is light and has good universality, and the detection efficiency of the roundness of the ball can be greatly improved.
SUMMERY OF THE UTILITY MODEL
In order to overcome the prior art problem, the utility model provides a detect frock, the detection that can be quick accurate detects out the change volume of spheroid circularity, improves the detection efficiency of spheroid circularity.
The technical scheme of the utility model, a ball valve spheroid circularity short-term test frock, including the locating lever, the location tray, the percentage table, the table pole, locating lever quantity is four, the locating lever all inserts in the through-hole around the location tray, the locating lever passes through the fix with screw on the location tray, the locating lever is parallel between two liang and the interval equals, the table pole is connected to the percentage table, the table pole inserts in the central through-hole of location tray, the central through-hole of location tray is the boss hole of falling, be equipped with the screw hole on the boss lateral wall, threaded hole has adjusting screw, the table pole is parallel with the locating lever, the locating lever bottom is the sphere of unified size.
The beneficial effects of the utility model are that, adopt the percentage table to arrange the locating lever in the middle of, the locating lever carries out the frock form of automatic centering, namely, make the automatic directional spheroid centre of sphere that awaits measuring of table pole axis, simple structure that messenger's frock can be done, the commonality is good, the overall arrangement is compact, small, one hand grips, only need lean on the frock to press the jump condition of the slide observation percentage table pointer of optional position on the spheroid sphere that awaits measuring can judge spheroidal circularity, it is poor to have avoided utilizing the few measurement accuracy of micrometer sampling point, many times measuring time is long, the problem of inefficiency, the problem of the operation error of measurement personnel micrometer has also been avoided simultaneously, locating lever or table pole have in addition if wearing and tearing can change at any time, the percentage table also can be changed at any time if there is precision error, the life of this frock has been prolonged. Meanwhile, the roundness detection of the machined ball body in a factory is improved in efficiency by using the tool, the time is saved, and the detection reliability is improved.

Detailed Description
As shown in fig. 2-4, a ball valve spheroid circularity short-term test frock, including the locating lever, the location tray, the percentage table, the table pole, locating lever quantity is four, the locating lever all inserts in the through-hole around the location tray, the locating lever passes through the fix with screw on the location tray, the locating lever is parallel and the interval equals between two liang, the table pole is connected to the percentage table, the table pole inserts in the central through-hole of location tray, the central through-hole of location tray is the inverted boss hole, be equipped with the screw hole on the boss lateral wall, there is adjusting screw in the screw hole, the length of setting tray is stretched down to the adjusting table pole, the table pole is parallel with the locating lever, the locating lever bottom is the sphere of uniform size, it is.
The working principle is as follows: adopt above-mentioned locating lever, location tray, percentage table and table pole's distribution structure can make the automatic directional spheroid centre of sphere that awaits measuring of table pole axis, when detecting the sphere circularity of spheroid orifice department or section department, the sight of percentage table position observation is not influenced by any, only needs simultaneously with the spheroid sphere that awaits measuring contact arbitrary three locating levers just can the automatic centering, namely, makes the automatic directional spheroid centre of sphere that awaits measuring of table pole axis.
Through the detection tool, the requirements of being unconstrained and quickly reading and judging the roundness of the ball body during the roundness detection of the ball body can be realized, and the detection efficiency is greatly improved.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
