It is scheduled in fixed seat, in order to do corresponding shear strength test to brake shoe by various plant equipment, to reduce work
Intensity, test period is reduced, improve shearing test efficiency.Groove can reduce weight, while reduce consumptive material.Groove surrounding is with consolidating
Fixed seat uniform wall thickness L, wall thickness L=12mm are formed between the outer wall of reservation, can be while fixed seat intensity be kept, to the greatest extent
Amount reduces consumptive material and reduces weight.Level meter can play a part of measuring levelness, so as to timely when levelness is not up to standard
Adjust the position of fixed seat.Protective plate, which had both played the steel plate for preventing from cutting off on brake shoe and collapsed, to fly to get to people or article, moreover it is possible to rises
The steel plate cut off on to collection brake shoe, in order to test its Material Strength and recycling.After the completion of brake shoe clamping,
Fixed seat is placed on test mechanical by supporting plate, by the collapsing length and angle of adjustable telescopic rod, adjusts fixed seat
Height and position and levelness, by motor and rotating disk, adjust the direction of fixed seat, after the completion of regulation, Retractive leg elongation, make pad
The bottom surface of plate touches with test mechanical table top, and keeps the height and position of fixed seat, levelness and direction before this, to be tried
When testing, supported by support base and supporting plate, and ensure that height and position, levelness and the direction of fixed seat do not occur at any time
Change.
