When the roller 44 contacts the first arc surface 511, the swing rod 42 is in a stop state; when the roller 44 contacts the upper inclined surface 513, the swing rod 42 swings rightward; when the roller 44 contacts the second arc surface 512, the swing rod 42 is in a stop state; when the roller 44 contacts with the inclined plane 513 below, the swing rod 42 swings leftwards, so that the swing rod 42 is driven to swing leftwards and rightwards in a reciprocating manner, and the swing rod stops at the limit positions on two sides; by the cooperation of the sliding groove 43 at the upper end of the swing rod 42 and the sliding rod 41, the moving block 37 and the push rod 39 are driven to reciprocate left and right, and stop at the limit positions at the left end and the right end. When the push rod 39 moves rightwards, the test plate 5 at the bottom of the groove body 4 is pushed between the first roller 58 and the second roller 60, the first roller 58 and the second roller 60 rotate in opposite directions, and the test plate 5 is conveyed out of the test box 2 through the material guide opening 63 at the time of stopping the push rod 39; when the push rod 39 moves leftwards and stops at the limit position, the plurality of test boards 5 above the push rod drop, the whole thickness of the whole test board group drops, then the pressing plate 6 presses downwards, so that the circulation is continued, the pressing plate 6 presses downwards each time, the thickness of the test board group is reduced relative to the last thickness, the output pressure value corresponding to the spring of the elastic brake actuator under different expansion lengths is correspondingly measured, the measurement is more intelligent, the measurement precision is high, and the measurement efficiency is also improved. In addition, the axle 48 rotates to drive the second pulley 50 to rotate, the second belt 62 drives to drive the fourth pulley 61 to rotate, the fourth pulley 61 rotates to drive the second roller 60 to rotate, the first roller 58 and the peripheral outer wall of the second roller 60 are clung to each other due to the elastic force of the second spring 56, so that the second roller 60 drives the first roller 58 to move in opposite directions, the first roller 58 can move along with the sliding block 55 in the vertical direction, the driving of test boards with different thicknesses can be met, and the test boards are clamped between the first roller 58 and the second roller 60 so as to be transported out, so that the thickness of the test boards can be changed, and the output pressure measurement is carried out by the elastic actuators meeting different specifications.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
