Description

A kind of tool detecting bayonet lock counterbore depth

Technical field

The utility model relates to connector technique fields, are used for bayonet lock locking type connector, especially a kind of detection bayonet lock The tool of counterbore depth.

Background technique

There are a variety of connection locking modes in connector, have bayonet, bayonet lock locking linking, screw-threaded coupling linking and Direct-inserting locking linking etc..In bayonet, bayonet lock locking type connector, bayonet, card is respectively adopted in the plug and socket of connector The structure of pin.When bayonet, bail type connector in practical application connect, dextrorotation coupling nut, when hearing " clicker " sound, Bayonet lock drops into bayonet, indicates that the plug and socket of connector is locked completely；When separation, then left-handed coupling nut, until It is kept completely separate.Prior art bayonet, bayonet lock locking type connector are equipped with bayonet lock on plug, and bayonet lock is by varus riveting Form is fixed in the pin hole of plug attachment cap.The problem is that the pine of the bayonet lock of attachment cap in actual use The phenomenon that moving, falling off is occurred repeatedly, and connector scrap of the product is caused, to find out its cause, be bayonet lock counterbore processing it is lack of standardization, cause Technique requirement is not achieved in the riveter sequence of turning over of bayonet lock and attachment cap pin hole, in addition, when testing to attachment cap bayonet lock counterbore, It is difficult to measure with the conventional measurer such as vernier caliper, and leads to the nonstandard reason of attachment cap bayonet lock counterbore size, how to design A kind of easy, rapid survey bayonet lock counterbore cubing, is the necessary means to solve the above problems.

Summary of the invention

The purpose of this utility model be in view of the deficiencies of the prior art and provide a kind of detection bayonet lock counterbore depth work Tool, the utility model use the step shaft member being made of one section of handle and one section of gauge, and a gauge design is cylindrical shape, in gauge Root be equipped with groove, the combination end face of gauge and handle is designed as cambered surface, is measured with gauge to attachment cap bayonet lock counterbore, Ensure the processing dimension specification of bayonet lock counterbore, it is ensured that bayonet lock and pin hole retain in varus riveting accurately turns over riveting space, this reality Have the advantages that simple and easy, measurement is accurate and measurement efficiency is high with novel.

Technical scheme of realizing the purpose of the utility model is that

A kind of tool detecting bayonet lock counterbore depth, it is characterized in that the tool was made of one section of handle and one section of gauge Step shaft member, the gauge are cylindrical shape, and the root of gauge is equipped with groove, and the combination end face of gauge and handle is cambered surface.

The utility model uses the step shaft member being made of one section of handle and one section of gauge, and a gauge design is cylindrical shape, Be equipped with groove in the root of gauge, the combination end face of gauge and handle is designed as cambered surface, with gauge to attachment cap bayonet lock counterbore into Row measurement, it is ensured that the processing dimension specification of bayonet lock counterbore, it is ensured that bayonet lock and pin hole retain that accurately to turn over riveting empty in varus riveting Between, the utility model has the advantages that simple and easy, measurement is accurate and measurement efficiency is high.

Detailed description of the invention

Fig. 2 is the product schematic diagram of attachment cap to be detected；

Fig. 3 is partial sectional view at A-A of Fig. 2；

Fig. 4 is the side view of Fig. 1；

Fig. 5 is the use state diagram of the utility model.

Specific embodiment

Refering to fig. 1, Fig. 4, the step shaft member that the utility model is made of one section of handle 1 and one section of gauge 2, the gauge 2 For cylindrical shape, the root of gauge 2 is equipped with groove 21, and the combination end face of gauge 2 and handle 1 is cambered surface 22.

The utility model works in this way:

Refering to fig. 1, Fig. 2, Fig. 3, Fig. 4, the test object of the utility model are the bayonet lock counterbores on attachment cap 3, are being connected Pin hole 31 is set on the wall of cap 3, to bayonet lock Hole chamfering 32 on the outer wall of attachment cap, forms bayonet lock counterbore, is blocked by detection Pin hole 31 is by attachment cap inner wall to the position of chamfering 32, therefore, it is determined that whether the processing dimension of bayonet lock counterbore standardizes.

The detection of bayonet lock counterbore:

Refering to fig. 1, Fig. 3, Fig. 5 hold handle 1, gauge 2 are filled in the bayonet lock counterbore to be detected by 3 inner wall of attachment cap, protect The cambered surface 22 for holding gauge 2 and the cambered surface of attachment cap inner wall are tangent, detect the circumference of 2 top surface of gauge and the circumference of counterbore chamfering 32 The registration of line, to determine whether bayonet lock counterbore is qualified.

The setting of the utility model groove:

Refering to fig. 1, Fig. 4, Fig. 5, the utility model are equipped with groove 21 in the root of gauge 2, i.e. groove 21 is arranged in handle 1 With the junction of gauge 2, when detection, once there are impurity in 3 bayonet lock counterbore of attachment cap, remaining impurity will fall into groove 21 Interior, impurity falls into the cambered surface 22 of handle 1 Yu gauge 2 when avoiding detection, and detection is caused to be judged by accident.

The setting of the utility model cambered surface:

Refering to fig. 1, Fig. 4, Fig. 5, for guarantee the 3 bayonet lock counterbore of attachment cap of different-diameter is detected, prevent gauge 2 with The combination end face of handle 1 and the tangent generation error of cambered surface of 3 different curvature radius of attachment cap, the utility model is in gauge 2 and handle The combination end face of hand 1 devises cambered surface 22, since the radius of curvature of the cambered surface 22 is much smaller than the curvature half of various 3 internal diameters of attachment cap Diameter, so when detecting, the utility model gauge 2 connects with the cambered surface 22 of handle 1 and the inner wall of 3 bayonet lock counterbore of attachment cap for line Touching, not only increases detection accuracy, but also meet and detect to the attachment cap pin hole 31 of different-diameter.
