Clamping fixture and method for testing torsional moment of panel knob of automobile air-conditioner

Abstract

The invention discloses a clamping fixture and a method for testing the torsional moment of a panel knob of an automobile air-conditioner. The clamping fixture for testing the torsional moment comprises a fixture body, wherein clamping blocks for clamping the knob are arranged on one side of the fixture body, and are arranged in pairs; one end of each clamping block is connected with the fixture body, a sliding chute is formed on each clamping block, sliding blocks matched with the sliding chutes are arranged on the fixture body, and the clamping blocks are connected with the fixture body in a way that the sliding blocks are matched with the sliding chutes; the other end of each clamping block has a planar or cambered structure which is matched with a clamping position of the knob; a bolt is arranged at one end of the clamping blocks connected with the fixture body, two ends of the bolt penetrate out of the clamping blocks, compression nuts are arranged at two ends of the bolt penetrating out of the clamping blocks, and in a working state, the compression nuts are compressed tightly on the bolt; and a connecting column which is connected with a torque meter is arranged on the other side of the fixture body. The method for testing the torsional moment comprises three steps. The clamping fixture and the method can meet testing requirements of knobs with different sizes and shapes, and the detection efficiency is high.

Description

technical field [0001] The invention relates to the field of automobile air conditioners, in particular to a torque test clamping tool for a panel knob of an automobile air conditioner and a torque test method thereof. Background technique [0002] The torque of the panel knob of the automobile air conditioner is an important index to measure the ergonomics of the control panel. Therefore, the torque of the panel knob must have a reasonable design value. At present, the measurement tool usually used in the panel knob torque test is a torque meter with a range of 0-100N. Knobs all need to involve separate knob clamping fixtures; on the one hand, these clamping fixtures will greatly increase the testing cost and resource consumption; on the other hand, every time a knob is tested, the fixture fixture needs to be connected to the torque meter once , not only increases the detection difficulty, but also consumes time and low detection efficiency.
