Abstract
The utility model discloses a kind of pin insulator internal thread checkout equipment, comprise inspection rule and holder, described inspection rule lower end is Thread check end, and described inspection rule are also provided with the through hole running through axis; The center of described holder is provided with the test rod perpendicular to holder direction, and described test rod upper end indicates scale; Described test rod upper end indicates scale, and test rod is through advising the zero graduation line position that position that top flushes is test rod after the through hole of described inspection rule with inspection; The external thread for carrying out the detection of pin insulator internal thread is carved with in described Thread check end outside, and the internal thread for connecting inspection rule is carved with in described thread measurement end inside.The utility model is simple and compact for structure, and production cost is low, can the screw thread process qualification rate of read check pin insulator internal thread and threaded hole height qualification rate soon, reduces proving time, promotes qualified efficiency, and easy to use, convenient operation.
Description
Technical field
The utility model relates to the production testing technical field of pin insulator, in particular, relates to a kind of pin insulator internal thread checkout equipment.
Background technology
Pin insulator is used for power-frequency voltage 6 ~ 20KV high ammonia syrings, in order to insulation and support wire, pin insulator internal thread is for installing metal screw, and wherein internal thread directly directly can process internal thread in idiosome forming process, also can process internal thread at core retainer plate endoporus.If machining internal thread in mucilage binding core retainer plate, then because core retainer plate belongs to metal master part, qualification rate is high and easily detect; But directly process internal thread on idiosome, then need through air-dry, sintering process, dry body becomes the shrinkage factor of porcelain often to have fluctuation, therefore, the direct internal thread processed on idiosome is needed entirely to examine; But general conventional tool is due to dimensional problem, being all difficult to use in the inspection of internal thread, therefore needing badly a kind of for checking the checkout equipment of pin insulator internal thread.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of pin insulator internal thread checkout equipment easy to use, simple to operate.
The utility model is achieved through the following technical solutions above-mentioned purpose: pin insulator internal thread checkout equipment, comprises inspection rule and holder, and described inspection rule lower end is Thread check end, and described inspection rule are also provided with the through hole running through axis; The center of described holder is provided with the test rod perpendicular to holder direction, and described test rod upper end indicates scale; Described test rod upper end indicates scale, and test rod is through advising the zero graduation line position that position that top flushes is test rod after the through hole of described inspection rule with inspection; The external thread for carrying out the detection of pin insulator internal thread is carved with in described Thread check end outside, and the internal thread for connecting inspection rule is carved with in described thread measurement end inside.
Further, described test rod is welded on holder center.
Further, the zero graduation line position on described test rod indicates a circle red-label, the yellow flag be carved with up and down in equidistant expression error range of zero graduation line position.
Further, described inspection rule upper end is also provided with the handle being convenient to hold.
The beneficial effects of the utility model are: the utility model is simple and compact for structure, and production cost is low, can the screw thread process qualification rate of read check pin insulator internal thread and threaded hole height qualification rate soon, reduce proving time, promote qualified efficiency, and easy to use, convenient operation.
Accompanying drawing explanation
Fig. 1 is inspection described in the utility model rule structural representations.
Fig. 2 is the structural representation of holder described in the utility model and test rod.
Fig. 3 be the utility model inspection rule and holder, test rod detection time constitutional diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Fig. 1 ~ 3, pin insulator internal thread checkout equipment, comprise inspection rule 1 and holder 2, described inspection rule 1 lower end is Thread check end 4, and described inspection rule 1 are also provided with the through hole running through axis; The center of described holder 2 is provided with the test rod 3 perpendicular to holder 2 direction, and described test rod 3 upper end indicates scale 6; Described test rod 3 upper end indicates scale 6, and test rod 3 is the zero graduation line position of test rod 3 through the position flushed with inspection rule 1 top after the through hole of described inspection rule 1; The external thread for carrying out the detection of pin insulator internal thread is carved with in described Thread check end 4 outside, and the internal thread for connecting inspection rule 1 is carved with in described thread measurement end inside.
Described test rod 3 is welded on holder 2 center.
Zero graduation line position on described test rod 3 indicates a circle red-label, the yellow flag be carved with up and down in equidistant expression error range of zero graduation line position.
Described inspection rule 1 upper end is also provided with the handle 5 being convenient to hold.
During use, be enclosed within by porcelain vase on the test rod 3 of holder 2, then screwed in the internal thread of porcelain vase by thread measurement end 4, if be up to the standards, then Thread check end 4 screws in internal thread hole smoothly; If disqualified upon inspection, then screw thread interferes, and thread measurement end 4 cannot screw in internal thread hole smoothly.After having inspected screw thread, whether whether the zero graduation line position observing test rod 3 and inspection rule 1 top at same level line or in error range, namely whether in the scope of two yellow flag, if whether the zero graduation line position of test rod 3 and inspection rule 1 top be at same level line or within the scope of yellow flag, then be up to the standards, on the contrary then defective.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
