Abstract
The utility model belongs to the technical field of installation of a clamp of a vibrating table and relates to an expanding-type thread binding sleeve. The expanding-type thread binding sleeve comprises a sleeve head and a sleeve body, the sleeve body is provided with internal threads and external threads, three through grooves are arranged along the longitudinal direction of the sleeve body to enable the sleeve body to form a triadius, an outer diameter of the sleeve body is larger than an inner diameter of an installation hole of a testing clamp, the top end of the sleeve body is a slant angle, and the minimum outer diameter of the slant angle is smaller than the inner diameter of the installation hole of the testing clamp. After the expanding-type thread binding sleeve is screwed in the testing clamp through a screwing tool, the triadius sleeve body expands due to self elasticity, the binding sleeve is automatically locked, the expanding-type thread binding sleeve cannot loosen due to vibration caused by the vibrating table along rotation of a bolt, a tested product can be effectively fixed, damage to the product caused by the vibration can be avoided, and reliability and safety of the tested product can be improved.
Description
Technical field
The utility model belongs to the mounting technique field of shake table clamp, relates to a kind of expansion screw thread coupling sleeve.
Background technique
In the vibration test fixing link of product, product and vibration tong need to be connected and fixed at present being internal and external threads formula steel bushing or directly holing at test fixture and add the mode that compresses screw of normal operation.This dual mode has certain defect.Adopt duralumin because the material of test fixture is most of, if directly boring in the above, the dismounting number of times is easy to damaged screw when higher.Present more employing be internal and external threads formula steel bushing, with vibration tong be common screw-thread fit, defective is the vibration that can produce along with the rotation of bolt and vibrating table in the process of dismounting and loosening even come off, and causes easily the damage that is subjected to trial product in the vibration processes.If the adding screw thread fastening glue when needing to change steel bushing because of wearing and tearing, but is difficult to dismounting.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of connection fastening and easy-off expansion screw thread coupling sleeve.
The technical solution of the utility model is: a kind of expansion screw thread coupling sleeve, comprise pullover and body, and described body is with internal and external threads; Vertically have three saturating grooves along body, making its body is Trident Type; The cover body diameter is greater than the internal diameter of test fixture mounting hole; The body top is the bevelling, and its minimum outer diameter is less than the internal diameter of test fixture mounting hole.
There is some screw-ins hole on the pullover top of above-mentioned coupling sleeve.
The beneficial effects of the utility model are: after by the screw-in instrument the utility model expansion screw thread coupling sleeve being screwed in test fixture, owing to the elasticity of Trident Type body self produces expansion, the auto lock coupling sleeve, the vibration that can not produce along with the rotation of bolt and vibrating table and becoming flexible, can effectively fixedly be subjected to trial product, avoid having improved the reliability and the Security that are subjected to trial product because vibration makes tested damage of product.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model expansion screw thread coupling sleeve;
Fig. 2 is that a kind of embodiment of the utility model expansion screw thread coupling sleeve shown in Figure 1 is along the sectional view of A-A line;
Fig. 3 is the right elevation of a kind of embodiment of the utility model expansion screw thread coupling sleeve shown in Figure 1;
Wherein, pullover, the 2-body of 1-, 3-internal thread, 4-outside thread, the saturating groove of 5-, 6-screw in the hole.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
With reference to figure 1, Fig. 2 and Fig. 3, a kind of expansion screw thread coupling sleeve comprises pullover 1 and body 2, and it is characterized by: described body 2 is with interior 3 outside threads 4; Vertically have three saturating grooves 5 along body 2, make its body 2 be Trident Type; Body 2 external diameters are than the large 0.04～0.05mm of internal diameter of test anchor clamps mounting hole; Body 2 tops are the bevelling, and its minimum outer diameter is less than the internal diameter of test fixture mounting hole.Pullover 1 top of coupling sleeve has three to screw in hole 6, is to use three to grab the Point of Strength that spanner is installed coupling sleeve.Above-mentioned pullover 1 is that " R " type and external diameter are greater than the cylindrical body of mounting hole.
After place, bevelling, body 2 top screws in the mounting hole of test fixture, grabbing spanner with three screws in coupling sleeve body 2 in the mounting hole of test fixture fully, because of the external diameter of coupling sleeve body 2 greater than the mounting hole interior threaded hole, so the process of installing will use larger power to screw in.
