Pull rod detection device utilizing magnetorheological fluid

Abstract

The invention relates to the technical field of pull rod detection equipment, in particular to a pull rod detection device utilizing magnetorheological fluid. The device comprises a tension rod detection device, the center of the tension rod detection device is movably connected with a threaded rod, and the left side and the right side of the tension rod detection device are movably connected withconical tooth frameworks; the left side and the right side of the tension rod detection device are movably connected with telescopic devices through threaded rods, and the inner side of the tension rod detection device is movably connected with a movable pull rod framework through a conical tooth framework. According to the pull rod detection device utilizing the magnetorheological fluid, the pull rod is arranged in the middle of the rod grabbing claw to be fixed, and device driving is started, the threaded rod rotates, the gears are driven to rotate through meshing between the gears, the gears drive the telescopic spring rods to move outwards through the sliding belts on the two sides, pushing force borne by the telescopic spring rods is normal pulling force of a pull rod used by people,electric power serves as drive, and the principle of magnetism generated by electricity means that when current passes through a metal wire, a circular magnetic field can be generated in the space around the wire.

Description

technical field [0001] The invention relates to the technical field of tie rod detection equipment, in particular to a tie rod detection device using magnetorheological fluid. Background technique [0002] Many toolbox manufacturers want to find a suitable pull rod for their toolbox, but the requirements for toolbox pull rods are not as low as those of luggage pull rods, and their lubricity and firmness are high. , It usually requires the staff to check the lubricity of the normal pulling of the tie rod and its pressure bearing quality. [0003] Usually, when testing the lubricity of the pull rod, the staff needs to manually pull the pull rod to separate it from the groove, so as to feel whether the two are lubricated and whether they can be pulled apart with normal force. However, the force used for manual detection is different. The result is not accurate enough, the operation is more troublesome, and the pressure sensor needs to be replaced to detect the pressure bearing...

[0003] Usually, when testing the lubricity of the pull rod, the staff needs to manually pull the pull rod to separate it from the groove, so as to feel whether the two are lubricated and whether they can be pulled apart with normal force. However, the force used for manual detection is different. The result is not accurate enough, the operation is more troublesome, and the pressure sensor needs to be replaced to detect the pressure bearing of the pull rod later, and a different machine needs to be replaced, which greatly increases the detection cost. In order to solve the above problems, the inventor proposed a method. A pull rod detection device using magnetorheological fluid
