Background

In the assembly process of a certain type of actuator, the stroke of the switch needs to be controlled, and unqualified switches are eliminated. The actuator causes the switch to transition from the pressed on state to the non-pressed off state by pushing open the spring piece. At present, no tool for measuring the stroke of the spring piece for switching on and off the switch aiming at key parameters is provided. Because the deformation of the spring piece can only be measured from the outer side of the actuator to measure the stroke of the actuator for switching on and off the switch in an appointed state, an assembler can measure the stroke by means of a method of holding the dial indicator by hands at present, the method cannot ensure that the dial indicator is perpendicular to a measuring surface during testing, meanwhile, the position of a measuring point of a head of the dial indicator, which is pressed on the spring piece, is not fixed, and the error of a measuring result is extremely large.

The support is made of high-strength steel, and the chuck is made of rubber.

The utility model discloses a use method does: place the actuator on testboard base, the actuator mounting hole passes two and is accurate the placing on testboard base that the diagonal angle was placed, passes two piece set of housing screws respectively again and is fixed in testboard base with the actuator after two pieces of packing rings on, so far, the actuator has pinpointed and fastened on this measurement frock. And after the shell of the dial indicator measuring shaft penetrates through the inner hole of the dial indicator clamping head of the test bench, two screws penetrate through the dial indicator clamping head of the test bench and are screwed to the dial indicator bracket of the test bench, and meanwhile, the dial indicator is also clamped and is parallel to the base of the test bench. Two screws penetrate through two bottom holes of the dial indicator bracket of the test bench and are screwed on the base of the test bench, so that the dial indicator, the dial indicator bracket of the test bench and the dial indicator chuck of the test bench are integrally positioned and fixed on the base of the test bench. The spring piece is shifted to enable the bending deformation of the spring piece to be gradually increased, the dial indicator head moves along with the spring piece and starts to measure, and when the spring piece is bent to just not extrude the switch any more so that the switch is switched off, the dial indicator measured value is the accurate switch stroke measured value.

The utility model has the advantages that:

the stroke measuring tool for the actuator switch avoids the possibility that errors are generated when a tester holds a dial indicator to measure, the dial indicator is not perpendicular to a spring piece, the testing position of the dial indicator head is inconsistent when the tester measures the dial indicator head, and the like, ensures that the testing result is more accurate and reliable, and simultaneously ensures that the testing process of the key assembly index of the actuator switch stroke is more standard.
