Description

Technical Field

[0001] The utility model belongs to the technical field of torque testing machines, and particularly relates to an auxiliary device for torque testing. Background Technique

[0002] A torsion testing machine is used to determine the mechanical properties of metal or non-metal specimens under torsion. This testing machine can apply torque to the specimen and measure the magnitude of the torque. It is a special equipment for torsion experiments. There are many types and different structural forms, but generally it consists of two basic parts: loading and force measurement.

[0003] After retrieval, Chinese Patent No. CN214667420U discloses an auxiliary device for calibrating a torque testing machine, including a base, a control panel is provided on the base, a top plate is provided above the base, columns penetrating the top plate are symmetrically provided on both sides of the upper end of the base, a cylinder is provided at the upper end of the top plate, a fixed shaft is provided at the lower end of the top plate, a workbench is provided at the upper end of the base, and clamping assemblies are provided at the lower end of the fixed shaft and the upper end of the workbench. Through the elastic action of the first spring and the second spring, the utility model can not only buffer the force of the device squeezing the tested object, avoid direct rigid extrusion of the tested object by the clamping block and cause damage, but also make several sleeves extend different lengths according to the surface of the tested object and abut against the uneven surface of the tested object through the reaction force of the first spring and the second spring, so as to limit and fix the tested object, so that the device can fix irregular objects, which is convenient to use and has strong practicability.

[0004] However, the above patent has the following problems:

[0005] Although through the elastic action of the first spring and the second spring, when the tested object is irregular in shape, several sleeves will extend different lengths according to the surface of the tested object and abut against the uneven surface of the tested object, so as to limit and fix the tested object, making the device fix irregular objects. However, when the torque testing device is in use, since the lengths of the objects to be tested are different, and the above torque testing device cannot adjust the distance between the two clamping mechanisms, when performing torque tests on objects of different lengths, different torque testing devices need to be used. Therefore, an auxiliary device is needed to adjust the distance between the two clamping mechanisms so that the torque testing device can test objects of different lengths. Therefore, an auxiliary device for torque testing is proposed. Content of the Utility Model

[0006] The purpose of the present utility model is to provide an auxiliary device for torque testing, which solves the problem that in the existing auxiliary device for torque testing, the torque testing device cannot adjust the distance between two clamping mechanisms during use. Therefore, an auxiliary device is needed to adjust the distance between the two clamping mechanisms so that the torque testing device can test objects of different lengths.

[0007] To solve the above technical problems, the present utility model is realized through the following technical solutions:

The two first clamping plates correspond to each other, the two second clamping plates correspond to each other, and the two fixing blocks are respectively fixedly connected with the fixed shaft and the two adjusting plates.

[0015] Furthermore, the four stabilizing rods are respectively fixedly connected to the four corners of the lower surface of the corresponding fixing block. Sliding grooves are formed on both sides of the surface of the fixing block. The moving block is slidably connected with the fixing block through the sliding groove. The second bidirectional threaded rod is rotatably connected to the inside of the fixing block through a bearing seat.

[0016] The utility model has the following beneficial effects:
