Abstract
The invention provides a multi-station alternating bending testing machine. A motor is controlled by a microcomputer; the motor is connected with a worm wheel and a worm rod by a belt wheel; the front end of a machine body is connected with a movable jaw seat and a fixed jaw seat by a tray; jaws are arranged between the two jaw seats; six fine adjusting devices are arranged at the upper part on the right side of the movable jaw seat and are used for adjusting clamping forces to a test sample by the six pairs of jaws; a nut seat is arranged at the lower part of the right side of the movable jaw seat and a hand wheel connection screw rod is connected with the movable jaw seat by the nut seat; an adjusting mechanism is arranged at the upper end of an oscillating bar device; the lower end of the oscillating bar device is connected with a small gear and the small gear is connected with a sector-shaped gear; the sector-shaped gear is connected with the worm rod and the worm rod by an eccentric wheel; the eccentricity degree of the eccentric wheel can be adjusted; the six pairs of jaws can be replaced; a micro-switch is arranged on each of the jaw seats; when the test sample is bent in place to be in contact with one micro-switch, a corresponding counter counts for one time; when one test sample is disconnected, the micro-switch corresponding to the test sample keeps fixed and the corresponding counter keeps previous data and does not work; and when the six counters do not work, the testing machine stops working.
