High-low temperature drawing toggle switch testing device

Abstract

The invention discloses a high-low temperature drawing toggle switch testing device, and belongs to the technical field of drawing toggle switch testing. The device comprises a heat preservation box for providing a high-low temperature environment and a testing mechanism mounted in the heat preservation box; and the testing mechanism comprises a base, a toggle servo motor, a bearing seat, a coupler, a toggle rotating shaft, an angle sensor, a swing arm, a switch fixing seat, a drawing servo motor, a cam, a sliding rail, a sliding block, a cam rod, a drawing force sensor, a connecting rod, a hoop, an L-shaped connecting plate and a toggling force sensor. The heat preservation box is adopted for providing a high-low temperature environment for the testing mechanism, and the testing mechanismcan normally work in the high-low temperature environment and is high in stability; the drawing force can be measured through the drawing force sensor; the toggling angle can be measured through theangle sensor, and the toggling force can be measured through the toggling force sensor; the multi-hole switch fixing seat is cooperated with the hoop, so that not only can a single drawing toggle switch be tested, but also a plurality of switches can be tested at the same time.

Description

technical field [0001] The invention relates to a high and low temperature pull-out toggle switch testing device, which belongs to the technical field of pull-out toggle switch testing. Background technique [0002] The pull-out toggle switch test uses a variety of sensors to repeatedly measure the pull-out force, toggle force, and toggle angle of the switch to understand the performance of the pull-out toggle switch. The high and low temperature pull toggle switch test refers to the measurement of the switch performance under the conditions of high temperature +90℃~low temperature -130℃. At present, switch detection equipment is mainly designed for normal temperature conditions. The test structure or accessories used may not be available under high and low temperature conditions of +90°C to -130°C. In addition, the existing pull-out toggle switch The test requires multiple measurements, and the pulling force, pulling force, and moving angle cannot be performed at the same ...

Problems solved by technology

At present, switch detection equipment is mainly designed for normal temperature conditions. The test structure or accessories used may not be available under high and low temperature conditions of +90°C to -130°C. In addition, the existing pull-out toggle switch The test requires multiple measurements, and the pulling force, pulling force, and moving angle cannot be performed at the same time. Therefore, a high and low temperature pulling toggle switch test device is designed, which has a high degree of automation and can operate normally under high and low temperature conditions.
