Abstract
The utility model discloses a screw plug gauge. A screw groove with screw pitch same to that of an internal screw in parts to be detected is screwed on an outer surface of the gauge body, a cylindrical helical spring is wound in the screw groove, and a projection part for detecting the internal screw of the parts to be detected is arranged on the cylindrical helical spring and projects from a gauge body surface on a screw groove port. The screw plug gauge is formed by the gauge body on which the screw groove is wound, and the helical spring with relatively high hardness, and the high hardness of the helical spring is used, thus the requirement for the surface hardness of the gauge body is effectively reduced, therefore the process difficulty of the screw plug gauge is reduced. The structure of the screw plug gauge is simple, the process is convenient, and the process cost of the screw plug gauge is saved.
Description
Technical field
The utility model relates to a kind of plug thread gauge.
Background technology
Insulated tension pole adopts internal thread to be connected with drive disk assembly in the high-voltage switch gear.At present, internal thread on the insulated tension pole as shown in Figure 1, the thread form of the internal thread 11 of its insulated tension pole 10 is the R shape screw thread of circular arc at the bottom of adopting tooth, when assembling, need to the internal thread of insulated tension pole be tested with plug thread gauge for the assurance assembly precision, because the internal thread in the insulated tension pole is not screw thread commonly used, therefore need the special plug thread gauge that is used for check of making, but when making this plug thread gauge, because of needs its skin hardness is processed to improve in its surface, therefore it is high, difficult large to process this plug thread gauge difficulty, and the cost of manufacturing is higher.
The utility model content
The purpose of this utility model is: provide a kind of manufacture difficulty low plug thread gauge.
The technical solution of the utility model is: a kind of plug thread gauge, comprise regulator, spiral is provided with the pitch thread groove identical with the seized part internal thread on the outside surface of described regulator, in thread groove, be arranged with cylindrical helical spring, be provided with the projection that protrudes regulator surface, thread groove notch place, is used for check seized part internal thread at cylindrical helical spring.
The internal diameter of described cylindrical helical spring is less than the path of thread groove.
Trench bottom at close its two ends of described thread groove offers respectively pin-and-hole, fixedly is coated with respectively the corresponding fixing register pin of pegging graft with pin-and-hole on the regulator at the two ends of described cylindrical thread spring.
Described thread groove is that semicircular arc groove consists of by the cross section, and described cylindrical helical spring is that circular steel wire wound forms by the cross section.
Described regulator comprises that by regulator and no-go gage regulator the diameter of the cylindrical helical spring that arranges on the described drift regulator is greater than the diameter of cylindricality thread bullet spring on the no-go gage regulator.
Plug thread gauge of the present utility model is comprised of the regulator that is arranged with thread groove and the higher screw thread spring of hardness and forms, it utilizes existing screw thread spring to have the characteristics of higher hardness, effectively reduce the requirement to the regulator skin hardness, thereby reduced the difficulty of processing of plug thread gauge, this plug thread gauge simple in structure, easy to process, the processing cost of saving the power plug thread gauge.

Fig. 1 is the structural representation of insulated tension pole internal thread;
Fig. 2 is the structural representation of the utility model plug thread gauge specific embodiment.
Embodiment
The specific embodiment of plug thread gauge of the present utility model as shown in Figure 2, this plug thread gauge is comprised of drift and no-go gage, wherein drift comprises drift regulator 1, and to be provided with by the cross section be the first thread groove 2 that semicircular arc groove consists of to spiral on an end outside surface of drift regulator 1; No-go gage comprises no-go gage regulator 6, and to be provided with by the cross section be the second thread groove 9 that semicircular arc groove consists of to spiral on the end outside surface of no-go gage regulator 6, is equipped with connector for connecting handle 5 at the other end of drift regulator 1 and no-go gage regulator 6.The pitch of the second thread groove 9 on the first thread groove 2 on the drift regulator 1 and the no-go gage regulator 6 all with insulated tension pole 10 to be detected in internal thread 11 identical, simultaneously, the radius of the first thread groove 2 is greater than the radius of the second thread groove 9.Be arranged with the first cylindrical helical spring 3 that is become by the coil component spring steel wire wound in the first thread groove 2 on drift regulator 1, the steel wire radius of this first cylindrical helical spring 3 equates with the radius of the first thread groove, be arranged with the second cylindrical helical spring 7 that is become by the coil component spring steel wire wound in the second thread groove 9 on no-go gage regulator 6, the steel wire radius of this second cylindrical helical spring 7 equates with the radius of the second thread groove 9, thereby so that be equipped with the projection that protrudes regulator surface, corresponding thread groove notch place on the first cylindrical helical spring 3 and the second cylindrical helical spring 7, the projection of the first cylindrical helical spring 3 and the second cylindrical helical spring 7 is configured for detecting the feeler gauge external thread of seized part internal thread.For guaranteeing that each cylindrical helical spring 3,7 cooperates closely with corresponding regulator 1,6, in the present embodiment, two cylindrical helical springs 3,7 internal diameter are less than thread groove 1 on the corresponding regulator, 6 path.In addition, the two ends of corresponding the first cylindrical thread spring 3 also offer pin-and-hole in the first thread groove 2, fixedly are coated with the register pin 4 of pegging graft and fixing with respective pin hole at the two ends of the first cylindrical helical spring 3; The two ends of corresponding the second cylindrical thread spring 7 also offer pin-and-hole in the second thread groove 9, fixedly are coated with the register pin 8 of pegging graft and fixing with respective pin hole at the two ends of the second cylindrical helical spring 7.
During use, drift regulator 1 is connected with handle 5 by connector respectively with no-go gage regulator 6, can detects the internal thread 11 of insulated tension pole 10.
Plug thread gauge of the present utility model utilizes thread groove and the volute spring offered on the regulator to consist of, it is not only simple in structure, and the size of feeler gauge can meet the accuracy requirement of detection fully, simultaneously, the feeler gauge screw thread that utilizes volute spring to form has reduced the requirement to the regulator skin hardness, thereby reduced the difficulty of processing of plug thread gauge, saved processing cost.
