Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of existing Glow Wire Tester, to provide a kind of and have the convenience of clamping through improvement, reaching the Glow Wire Tester that drives the test product dolly by counterweight, pulley traction rope by motor, clutch coupling, single-rail.
The technical solution of the utility model is achieved like this, and it comprises glowing filament and attemperating unit thereof; The test product dolly; Power-driven mechanism and the automaton thereof formed by the driven by motor guide rail; The permanent pulling force drive unit of forming by counterweight, pulley traction rope.Be characterized in:
A, power drive adopt motor to mesh through clutch coupling and single-rail, the test product dolly place single-rail before
It is to adopt an end to hang the traction rope of standard test weight by pulley and test product dolly that end, permanent pulling force drive
The front end bottom be connected;
B, power-driven mechanism and automaton thereof place in the seal closure at test product dolly rear portion;
C, standard test weight, pulley place in the glowing filament lower seal cover;
Be equipped with the magnetic test product stationary installation that to load and unload test product fast on D, the test product dolly;
E, be equipped with motor-driven and hang the automatic switching control equipment that the permanent pulling force of traction rope of standard test weight drives, with
Break away from motor-driven in a flash at test product contact glowing filament, switch to the permanent pulling force of traction rope and drive.
Since used single-rail, compact conformation, and matching requirements are low; The test product dolly places the guide rail front end, then make test product region and mobile space big, be convenient to lubricate, clean, maintain, guide rail and driving mechanism and counterweight pulley blocks place in the seal closure, reduce the influence of the pollutant of test generation to the driving of test product dolly.It is fast and convenient with magnetic test product stationary installation test product to be clamped.The automatic switching control equipment that power drive and permanent pulling force drive makes test product dolly advance and retreat automatically flexibly, avoids the acceleration bump, and test pressure is accurate.
