Abstract

The invention provides an L-shaped support for cabin quality characteristic measurement, relates to the L-shaped support and is to solve the problems of low measurement precision and poor measurement accuracy since during cabin quality characteristic three-dimensional parameter precision test in the prior art, measurement of three-dimensional mass center and rotational inertia can be finished through multiple lifting and mounting of a product to be tested. The L-shaped support comprises a base, a support, a screw rod, a nut, a handle, two positioning blocks, two linear guide rails, two bearing bases and four sliding blocks. The two linear guide rails are arranged on the base, and one positioning block is arrange close to the right end of each linear guide rail; the screw rod is arranged between the two linear guide rails; the two ends of the screw rod are fixedly equipped with the bearing bases respectively; the screw rod is in rotation connection with the bearing bases; the bearing bases are fixedly arranged to cross beams of a rectangular frame body respectively; the nut is sleeved on the screw rod; the sliding blocks are arranged on the linear guide rails; and the bottom end surface of the support is fixedly arranged on the nut and the sliding blocks. The L-shaped support is used for cabin quality characteristic measurement.

Description

technical field [0001] The invention relates to an L-shaped bracket, in particular to an L-shaped bracket used for measuring cabin quality characteristics. Background technique [0002] In order to complete the precision test of the three-dimensional parameters of the quality characteristics of the cabin, it is necessary for the product to be tested to achieve a certain pose transformation on the test equipment. The commonly used method is to hoist the product to be tested multiple times and clamp it multiple times to complete the measurement of the three-dimensional center of mass and moment of inertia. This leads to the problems of low measurement accuracy and poor measurement accuracy. However, in the prior art, there is also a bracket that can realize the measurement of the three-dimensional center of mass and moment of inertia for the product once installed, and it is necessary to provide a device to solve such problems. "Based on the above, the application number is 2...
