Abstract
The utility model, which belongs to the mechanical technology field, provides a screen plate for a nut, so that technical problems including the low test efficiency and the like in the prior art can be solved. The screen plate comprises a panel; a plurality of screening holes that are step holes are arranged on the panel, wherein the diameter of the large end of each screening hole is a maximum value of an external diameter error of a tested nut and the diameter of the small end of the screening hole is a minimum value of the external diameter error of the tested nut. According to the utility model, the multiple screening holes are used to screen a nut. When the dimension of the tested nut is larger than the maximum value of the manufacturing error, the nut can not enter a screening hole; and when the dimension of the tested nut is less than the minimum value of the manufacturing error, the tested nut is dropped out from the small end of a screening hole; and only a nut with the dimension within the manufacturing error zone can be kept in a screening hole, so that the screening can be carried out conveniently.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of screen plate of nut.
Background technology
Nut is exactly nut, the part that is screwed in to play the role of fastening with bolt or screw rod, all manufacture a kind of element that machinery must usefulness. nut of a great variety, we common are GB, the English mark, American Standard, day target nut. nut is divided into several large types such as carbon steel, high strength, stainless steel, plastic-steel according to the difference of material. be divided into common, nonstandard, (always) GB, new national standard, made in U.S.A, made in Great Britain, moral mark according to the different standard No. of the corresponding country of product attribute.Vary in size, screw thread is not divided into different specifications. and general GB, moral mark represent (for example M8, M16) with M, and made in U.S.A, English system then represents specification (such as 8#, 10#, 1/4,3/8) with mark or #.
The at present manufacturing of nut processing is all produced in enormous quantities, and its finished product that produces need to be through check, and at present check all is that the workman manually carries out, and the power of tests rate is lower, can't satisfy industrial demand.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and the screen plate of the high nut of a kind of screening effeciency is provided.
The purpose of this utility model can realize by following technical proposal:
A kind of screen plate of nut, it is characterized in that, this screen plate comprises a panel, offer several screen holes on the described panel, described screen holes is a stepped hole, the outside diameter of this screen holes is tested nut detector for outer diameter error maximal value, and the end diameter of described screen holes is tested nut detector for outer diameter error minimum value.
In the screen plate of above-mentioned a kind of nut, each screen holes is evenly distributed on panel, is some horizontally-arrangeds and some vertical setting of types.
In the screen plate of above-mentioned a kind of nut, the quantity of described horizontally-arranged is 40 to 60 rows, and the quantity of described vertical setting of types is 20 to 40 rows.
Compared with prior art, advantage of the present utility model is as follows:
1, this screen plate designs several screen holes and screens nut, when tested nut during greater than the foozle maximal value, this nut can not enter in the screen holes, when tested nut during less than the foozle minimum value, will drop from the small end of screen holes, only the nut in the foozle interval just can be stayed in the screen holes, thereby finishes screening easily.
Description of drawings
Fig. 1 is the structure front elevational schematic among this screen plate embodiment.
Fig. 2 is the structure schematic side view among this screen plate embodiment.
Among the figure, 1, panel; 2, screen holes.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, this screen plate comprises a panel 1, offers several screen holes 2 on the panel 1, and screen holes 2 is a stepped hole, the outside diameter of this screen holes 2 is tested nut detector for outer diameter error maximal value, and the end diameter of screen holes 2 is tested nut detector for outer diameter error minimum value.Each screen holes 2 is evenly distributed on panel 1, is some horizontally-arrangeds and some vertical setting of types.The quantity of horizontally-arranged is 40 to 60 rows, and the quantity of vertical setting of types is 20 to 40 rows.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
