Torque wrench life testing machine

Abstract

The present invention discloses a torque wrench life testing machine which comprises a testing table, a torque testing mechanism, a torque loading mechanism and an electric control cabinet. The testing table comprises a table frame and a work bench arranged on the table frame. The torque testing mechanism comprises a torque sensor, a drive adapter, a crank connection rod mechanism, a speed reducer gearbox and a motor. The work bench is provided with a hollow mounting frame. The torque sensor and the drive adapter are installed in the middle cavity of the mounting frame. The drive adapter is under the torque sensor. The convex square head of the lower end of the torque sensor extends into the concave square hole of the upper end face of the drive adapter. Both the speed reducer gearbox and the motor are fixedly connected to the table frame. The motor is connected to the convex square head of the lower end of the drive sensor through the speed reducer gearbox and the crank connection rod mechanism. The torque loading mechanism is arranged on the work bench corresponding to the torque sensor. The circuit system of the electric control cabinet is electrically connected to the motor. The quality control problem of a torque wrench of a domestic producer is solved and optimized.

Description

technical field [0001] The invention specifically relates to a torque wrench life testing machine, which is used for the type test of a manual torque wrench. Background technique [0002] In actual work, manufacturers must regularly conduct type tests on the torque wrenches they produce, including 50,000 durability tests. The newly developed torque wrench needs to be type-tested to ensure that the torque wrench meets the requirements stipulated in the standard, so as to avoid the torque value deviating from the assembly requirements in subsequent use, causing potential accidents, and even safety accidents such as torque wrench breakage. [0003] It is obviously unrealistic to conduct the above tests on torque wrenches by manpower, and most domestic enterprises do not have automatic testing equipment for this. [0004] In view of the above problems, there is an urgent need in the prior art for a torque wrench life testing machine that can automatically type test a manual tor...
