A fixture load force measuring device

Abstract

The invention discloses a device for measuring the carrying capacity of a clamp. The device comprises a base and an upright installed perpendicularly to the base. A plurality of guiding rails used for fixing a pulley lever are arranged on the upright. One end of the pulley lever is fixed to the guiding rails, the guiding rails are evenly distributed from top to bottom in sequence in the length direction of the upright, the pulley lever is fixed to the inner portion of the guiding rails through bolts, a plurality of clamping grooves used for fixing the pulley lever are formed in the guiding rails, one end of the pulley lever is fixed in the clamping grooves of the guiding rails, the other end of the pulley lever is provided with a pulley, one end of a hanging rope penetrates through the pulley and is connected with a weight and the other end of the hanging rope is provided with a hanging ring. The device for measuring the carrying capacity of the clamp and the clamp are fixed to the same plane, the offset of a clamp mechanism is measured through the suspending hanging force of the weight, according to the change of measured data before force receiving of the clamp and after the force receiving of the clamp, whether the carrying capacity of the clamp is qualified or not is judged through a three-coordinate measuring instrument, and influence, caused by the fluctuation quantity of the clamp in the force receiving state, on the size of an automobile body is avoided.

Description

technical field [0001] The invention relates to a clamp load force measuring device. Background technique [0002] In the design and manufacture of fixtures in the automobile manufacturing industry, the load force of the fixture reflects the fluctuation of the fixture positioning dimension of the mechanism under long-term stress. The confirmation of the mechanism load force of the fixture is only based on empirical evaluation, which often cannot accurately reflect the real state. . At present, there is no easy way to measure the load force of the fixture. It is impossible to quickly judge the load force of the fixture during fixture debugging and tooling delivery, which leaves a great hidden danger to the stability of the fixture during the mass production process. Affect the service life of the fixture. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fixture load force measuring device for the existing probl...
