Description
Technical Field
[0001] The utility model relates to the technical field of nut strength detection, in particular to a nut locking micro-controlled torsion testing machine. Background Art
[0002] The microcomputer controlled self-locking nut torsion testing machine is mainly suitable for factories and mining enterprises, and is widely used in the manufacturing and use of self-locking nuts in aviation, aerospace railways, steel, automobiles, bridges, subways and scientific research institutes. It is a detection device for the locking performance of self-locking nuts.
[0003] Most existing torsion testing machines can only limit the position of rod-shaped screws. When testing nuts that need to be installed on U-shaped or other special-shaped screws, it is difficult to fix the special-shaped nut rods, so rod-shaped screws with the same specifications as the special-shaped screws are used as test substitutes. Not using the original screws for testing is likely to affect the detection accuracy of the nut. At the same time, existing torsion testing machines mostly use clamps to clamp and fix the nuts, and only use friction to ensure the stability of the nuts in the left and right directions, which has poor safety.
[0004] Therefore, it is necessary to provide a new nut locking micro-controlled torsion testing machine to solve the above technical problems. Utility Model Content
[0005] In order to solve the technical problem that the existing torsion testing machine is difficult to fix the U-shaped screw and difficult to ensure the stability of the nut, the utility model provides a nut locking micro-controlled torsion testing machine.

[0014] The utility model provides a nut locking micro-controlled torsion testing machine:
[0015] 1. The guide rail, slider and locking piece can be used to clamp and fix the nut without affecting the normal movement detection of the nut. The guide rail can limit the movement path of the slider to prevent the slider from easily detaching from the torsion test machine body, thereby increasing the stability of the nut. The limit plate can prevent the nut from directly contacting the torsion test machine body. The adjustment block can make it easier to rotate the threaded rod. The position of the limit block can be adjusted by rotating the threaded rod. The limit block is close to the limit plate, which can close the left and right movement path of the nut. Compared with relying solely on friction to stabilize the nut, it can more effectively prevent the nut from moving out. The fixing plate can ensure that the threaded rod does not contact the card plate body, ensuring that the threaded rod can rotate normally;
[0016] 2. The limit block can be limited by the limit groove to prevent the limit block from rotating with the threaded rod and making it difficult to adjust the position of the limit block. The limit groove can make the limit block extend to the other side of the card plate body more easily. The ball bearing can ensure the stability of the adjustment block and make the adjustment block rotate more smoothly. By adjusting the extension length of the output rod of the electric telescopic rod, the two clamping blocks can be brought close to each other, so that the bolt can be clamped and fixed. The card slot can ensure that the U-shaped bolt can be normally extended into the screw fixing piece to prevent one side of the U-shaped bolt from contacting the screw fixing piece, resulting in instability of the U-shaped bolt;
[0017] 3. The anti-slip pad can increase the friction between the clamp block and the bolt, thereby increasing the stability of the clamped bolt. The anti-slip pattern can further increase the stability of the clamping nut of the clamping plate body. The protective shell can protect the test environment when the torsion tester body is running to detect the nut. The test appearance of the nut can be directly observed from the outside through the observation window. The moving distance of the slider can be more intuitively understood through the scale line. The bolts and nuts can be installed and removed more easily by opening the movable door. The stability of the movable door when closed can be ensured by the lock. BRIEF DESCRIPTION OF THE DRAWINGS
