The principle of this programme is such: because guide rod is connected with the crank be hinged on support, when crank, the roller be hinged on guide rod is rolled along guide rail, because guide rail is hinged with vertical mast moving up and down, when roller is rolled on guide rail, the hinge of horizontally disposed connecting rod in frame can be driven to rotate, because the clamping part of connecting rod and mounting spring is hinged, in connecting rod swing process, spring is made to be subject to downward alternate load, meanwhile, the hydraulic cylinder of frame top utilizes pump take out the liquid in pressure cylinder and start working, piston driving clamping part in hydraulic cylinder moves upward, make the alternate load that spring is subject to upwards, thus complete the test of cupping machine to the static load of spring.
The invention has the advantages that: the leverage of this cupping machine, be used on the cupping machine to spring, structure is simple, test easy to operate, greatly can improve the test efficiency of spring.
Preferably, described vertical mast is connected with worm gear, and described worm gear is connected with control handle by linkage, by control handle and worm gear, vertical mast can be driven to move up and down, thus guide rail is rotated, can regulate the size of load with this.
Preferably, the clamping part of described mounting spring comprises upper grip and is hinged on the lower chuck on connecting rod, described upper grip connecting fluid cylinder pressure, described spring fitting is between upper grip and lower chuck, when testting the spring be arranged between upper grip and lower chuck, piston in hydraulic cylinder will drive upper grip to rise, and lower chuck moves downward and extension spring, makes spring can be subject to the alternate load at upper and lower two ends.
Preferably, described base is also provided with bearing, described guide rail is hinged on bearing, guide rail can be rotated by the hinge on bearing, installation, convenient disassembly.
