Abstract
The utility model relates to the technical field of machinery, in particular to a separating type wire thread insert for a testing machine. A first step hole is formed in a locating sleeve, the front end of the first step hole is a round through hole, the rear end of the first step hole is a rectangular through hole, a core sleeve is embedded in the first step hole in the locating sleeve, a second step hole is formed in the core sleeve, the front end of the second step hole is a round threaded hole, and the rear end of the second step hole is a round through hole. Compared with the prior art, the separating type wire thread insert can replace a nut for testing, the problem that a short bolt can not be tested through a nut in the testing machine is solved, and short bolt testing is more convenient; in addition, after the core sleeve loses efficacy, the separating type wire thread insert can continue to be used after the core sleeve is replaced, and cost is saved.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of separated type screw insert for testing machine.
Background technique
On ZWICK testing machine, when lag bolt is carried out to the dependence test of friction factor, because the length of bolt is shorter, cannot test with nut.
Therefore, need to design a kind of separated type screw insert for testing machine that can make lag bolt test.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of separated type screw insert for testing machine that can make lag bolt test is provided.
In order to achieve the above object, the utility model has designed a kind of separated type screw insert for testing machine, it is characterized in that: in setting sleeve, be provided with step hole one, the front end of step hole one is manhole, the rear end of step hole one is rectangular through-hole, and core retainer plate is embedded in the step hole one of setting sleeve, is provided with step hole two in core retainer plate, the front end of step hole two is round thread hole, and the rear end of step hole two is manhole.
The front end of described core retainer plate protrudes outside setting sleeve.
Described core retainer plate is made up of base plate and cylinder, and cylinder is fixed on the center of top of base plate, and base plate cross section is rectangular, and the cross section of cylinder is rounded.
The bottom sides of described setting sleeve is provided with two slotted eyes.
Described setting sleeve is fixed on testing machine.
The tapped hole of described step hole two is connected with bolt.
The utility model compared with the existing technology, has designed split type screw insert, and split type screw insert can replace nut to test, and having solved lag bolt cannot carry out test problem at testing machine nut, thereby makes the test of lag bolt more convenient; In addition,, after core retainer plate lost efficacy, split type screw insert only need be changed core retainer plate and just can continue to use, and provides cost savings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model setting sleeve parts.
Fig. 3 is the plan view of the utility model setting sleeve parts.
Fig. 4 is the structural representation of the utility model core retainer plate parts.
Fig. 5 is the plan view of the utility model core retainer plate parts.
Referring to Fig. 1-Fig. 5,1 is setting sleeve; 2 is core retainer plate; 3 is slotted eye; 4 is step hole one; 5 is step hole two.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1-Fig. 5, the utility model is a kind of separated type screw insert for testing machine.In setting sleeve 1, be provided with step hole 1, the front end of step hole 1 is manhole, the rear end of step hole 1 is rectangular through-hole, core retainer plate 2 is embedded in the step hole 1 of setting sleeve 1, in core retainer plate 2, be provided with step hole 25, the front end of step hole 25 is round thread hole, and the rear end of step hole 25 is manhole.
In the utility model, for the ease of the replacing of core retainer plate 2, the front end of core retainer plate 2 protrudes outside setting sleeve 1, and core retainer plate 2 is made up of base plate and cylinder, and cylinder is fixed on the center of top of base plate, and base plate cross section is rectangular, and the cross section of cylinder is rounded.
The bottom sides of setting sleeve 1 is provided with two slotted eyes 3.
Setting sleeve 1 is fixed on testing machine.The tapped hole of step hole 25 is connected with bolt.
The utility model has designed split type screw insert, and split type screw insert can replace nut to test, and having solved lag bolt cannot carry out test problem at testing machine nut, thereby makes the test of lag bolt more convenient; In addition,, after core retainer plate 2 lost efficacy, split type screw insert only need be changed core retainer plate 2 and just can continue to use, and provides cost savings.
