Disclosure of Invention
The invention aims to overcome the defects and provide a barrel-shaped nut test tool which enables the test state to be closer to the working state of a product during assembly and use, better reflects the actual performance data of the product and is beneficial to the detection and research of the test performance of the product and a using method thereof.
The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:
the invention discloses a barrel-shaped nut test tool, which comprises a wrenching body, a chuck and a gasket and is characterized in that the wrenching body is provided with a clamping head; one end of the wrench is provided with an integrated clamping groove, one end of the gasket is provided with an integrated clamping head, the clamping head is clamped into the clamping groove, and the other end of the wrench is provided with an integrated clamping head.
And a semicircular groove is formed in the clamping head.
And through holes are formed in the middle parts of the gasket and the clamping head.
The collets are triangular.
The invention relates to a using method of a barrel-shaped nut testing tool; comprises the following steps;
1) Mounting bolts and nuts;
placing a nut into a semicircular groove arranged on the chuck, and screwing a bolt into the nut through the washer and the chuck;
2) Clamping and mounting by wrenching;
arranging a chuck which is integrated with the other end of the wrenching and clamping the chuck on a three-jaw chuck of a test torsion machine;
3) Clamping and mounting the bolt;
connecting a hexagonal head of the bolt with the other three-jaw chuck of the torque machine, and clamping a chuck into a clamping groove;
4) Performing simulation test;
the torque machine rotates to drive the chuck, the chuck drives the wrench to rotate, the wrench drives the clamping groove to rotate, the clamping groove drives the chuck to rotate, the chuck drives the nut to rotate, and the tightening torque is applied to the rotation of the bolt and the nut through rotation, so that the tightening torque detection and the installation performance detection are carried out.
Compared with the prior art, the invention has obvious beneficial effects; the technical scheme shows that: the one end of the wrench is provided with an integrated clamping groove, the one end of the gasket is provided with an integrated clamping head, the clamping head is clamped in the clamping groove, and the other end of the wrench is provided with an integrated clamping head. The loading face dop of packing ring adopts the face of cylinder with the pilot hole unidimensional, and nut and packing ring can be fine laminating in the testing process to because the increase of contact surface, can not produce the deformation phenomenon that nut and packing ring correspond the too big production of local atress in the testing process, experimental frock keeps unanimous when using with the assembly, and the data when experimental data is close to the in-service use more, the actual performance data of better reaction product. Meanwhile, in the process of screwing the nut in a rotating mode, a plane with the width being consistent with that of the nut is machined on the side face of the gasket and used for screwing the nut, the gasket is screwed together in the screwing process, the nut and the gasket are prevented from rotating and displacing due to the moment generated in the screwing process, and the assembling face can be well attached. And applying tightening torque through rotation, and performing tightening torque detection and installation performance detection. The test state is closer to the working state of the product during assembly and use, the actual performance data of the product is better reflected, and the test performance detection and research of the product are facilitated.
