Problems solved by technology

However, the application aims to measure the contact pressure of the entire transfer switch. At this time, it has been assembled into a finished product and the patent measures N sets of data, so the measured data has a large error. For those who need to accurately control the final pressure of the contact The product cannot achieve the purpose of pre-detection and improvement. It is known that the measurement transmission part of the invention is a slider sliding transmission. This kind of transmission has poor stability. Measurement results are highly disturbed

Embodiment

[0023] A moving contact final pressure detection mechanism, its structure is as follows figure 1 As shown, it includes a positioning fixture 2 for placing the moving contact 1 to be tested, which is movably connected to the base 4 through four screws, and can be disassembled and replaced according to the size of the moving contact 1 to be tested. Also be provided with the horizontal adjustment support 14 of adjusting its horizontal position below base 4, be connected with the lead screw 11 of servo motor 3, lead screw 11 is supported through support 12, be provided with on lead screw 11 and move up and down along lead screw 11. The pressure head 9 has a built-in pressure sensor, and the screw 11 is used to ensure the stability and accuracy of the transmission, reducing the error caused by the measurement system. In addition, the screw 11 is equipped with a scale 13, so that the pressure head 9 can be detected in real time. Location.

Abstract

The invention relates to a moving contact terminal pressure detection mechanism comprising a positioning clamp which is used for placing a moving contact to be detected and flexibly connected on a base, a lead screw which is connected with a servo motor, wherein a pressing head moving upwardly and downwardly along the lead screw is arranged on the lead screw, and a displayer which is provided with a data processing module and receives pressure detected by the pressing head and displays pressure. Compared with mechanisms in the prior art, the moving contact terminal pressure detection mechanism has characteristics of being simple in structure, intelligent, high in compatibility, low in energy consumption, low in cost, high in effect, long in replacement cycle and convenient to maintain and provides a better detection prevention platform for guaranteeing the great quality of a circuit breaker.

Description

technical field [0001] The invention relates to a detection mechanism, in particular to a detection mechanism for the final pressure of a moving contact. Background technique [0002] At present, the moving contact of the circuit breaker is directly used to assemble the product after the assembly is completed, and there are few detection devices for related detection. The most important parameter --- the final pressure of the contact is not controlled at all. This parameter is directly It affects the breaking capacity and protection characteristics of the entire circuit breaker; if it is retested after assembly, it will inevitably cause waste of manpower and material resources, and if it flows to the final customer, it will cause more serious personal and property safety, and even major accidents. [0003] Chinese patent CN102840934A discloses a transfer switch contact pressure detection device, including a workbench for positioning and clamping the transfer switch, a signal...
