Abstract
The utility model discloses a steel cap tension breaking tooling for a suspension insulator. The tooling comprises a pull rod and a clamping block which are movably connected with each other, wherein the lower half segment of the pull rod and the clamping block are positioned in a steel cap; the clamping block is formed by at least four cushion blocks matched with each other; and the clamping block is propped against the flange of an opening of the steel cap. According to the utility model, the process that the steel cap and the pull rod are fixed together by using a cement adhesive is not required; and the solidification of the cement adhesive is not necessary, so that materials are saved and a detection result is obtained in time. Therefore, the production speed is accelerated.
Description
Technical field
The utility model belongs to the technical field of electric porcelain insulator, relates in particular to a kind of suspended insulator steel cap tensile failure frock.
Background technology
At present when suspension insulator steel cap being carried out the test of pull weights strength failure, all be that the steel cap is cut or polish jade with an emery wheel at product or special-purpose test with the cement glue mucilage binding, treat that its cement conservation cycle then carries out tensile failure test again, not only waste material, and can not in time draw assay, affect manufacturing schedule.
The utility model content
The technical problems to be solved in the utility model provides a kind of suspended insulator with steel cap tensile failure frock, can in time draw assay, and not need cement glue.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of suspended insulator steel cap tensile failure frock, comprise pull bar and the fixture block that is flexibly connected with pull bar, the size of pull bar bottom is less than the steel cap cavity size at narrow place, the lower semisection of pull bar and fixture block place in the steel cap cavity, described fixture block is comprised of at least four cushion blocks that cooperatively interact, greater than the steel cap cavity size at narrow place, the flange of fixture block and steel cap opening part offsets to the distance of pull bar center line at the fixture block edge after being connected with pull bar.
In the foregoing description, the size at each position means: the width on this place's horizontal direction, and to describe the interference and collision possibility at each position.
Compared with prior art, the utility model has the advantage of: the lower semisection of pull bar and fixture block place in the steel cap cavity, the flange of fixture block and steel cap opening part offsets, be connected to during use on corresponding puller system and the equipment, continue to increase pulling force until the steel cap destroys, do not need with cement glue steel cap and pull bar to be fixed together, do not need to wait cement glue to solidify yet, save material, can in time draw assay simultaneously, accelerated manufacturing schedule.
Further, for easy to assembly, described fixture block and pull bar are slidingly connected, and the bottom of pull bar is provided with limit base, and the size of described limit base bottom is less than the steel cap cavity size at narrow place, in order to limit base can be placed in the steel cap cavity equally.
Further, because of the stressed maximum in the bottom of pull bar, described pull bar lower semisection is that diameter is from little to large taper.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is the structural representation that the utility model suspended insulator is used steel cap tensile failure frock embodiment.
Embodiment
As shown in Figure 1, a kind of suspended insulator of the utility model steel cap tensile failure frock, comprise pull bar 1 and the fixture block 2 that is flexibly connected with pull bar 1, the size of pull bar 1 bottom is less than the steel cap cavity size at narrow place, the lower semisection of pull bar 1 and fixture block 2 place in the steel cap cavity, described fixture block 2 is comprised of at least four cushion blocks that cooperatively interact, and greater than the steel cap cavity size at narrow place, the flange 3 of fixture block 2 and steel cap opening part offsets to the distance of pull bar center line at the fixture block edge after being connected with pull bar.For easy to assembly, described fixture block 2 is slidingly connected with pull bar 1, and the bottom of pull bar 1 is provided with limit base 4.Because of the stressed maximum in the bottom of pull bar 1, described pull bar 1 lower semisection is that diameter is from little to large taper.
The lower semisection of the utility model pull bar 1 and fixture block 2 place in the steel cap cavity, fixture block 2 offsets with steel cap opening flange 3, be connected to during use on corresponding puller system and the equipment, continue to increase pulling force until the steel cap destroys, do not need with cement glue steel cap and pull bar 1 to be fixed together, do not need to wait cement glue to solidify yet, saved material, simultaneously can in time draw assay, accelerate manufacturing schedule.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (3)
1. a suspended insulator is with steel cap tensile failure frock, it is characterized in that: comprise pull bar and the fixture block that is flexibly connected with pull bar, the size of pull bar bottom is less than the steel cap cavity size at narrow place, described fixture block is comprised of at least four cushion blocks that cooperatively interact, after being connected with pull bar the fixture block edge to the distance of pull bar center line greater than the steel cap cavity size at narrow place.
