The following describes in detail the operation of a test bench 100 according to the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, in the initial state, the table 103 and the bottom plate 107 are substantially in parallel and aligned in the longitudinal direction. The support bar 121 supports the table top 103. The test piece is loaded onto the table 103 through the mounting hole 126. When the test bench 100 starts to operate, an operator controls the second cylinder 120 to retract through the controller, and the gear block is separated from the rack 118. Then, the pulling device 112 is started to control the first oil cylinder 113 to shrink, the piston rod 114 pulls the first cross rod 105, so that the first cross rod 105 slides from one end to the other end of the chute 110, and the first cross rod 105 keeps a distance from the bottom plate 107 and slides to the middle in a direction parallel to the bottom plate 107 due to the fact that the length direction of the chute 110 is consistent with the length direction of the bottom plate 107. The first cross bar 105 drives the table top to move relative to the bottom plate 107 through the table top supporting piece 104, and as the length direction of the supporting groove 106 forms a set included angle with the plane where the table top 103 is located, the bearing 111 of the bearing seat 109 moves from one end to the other end of the supporting groove 106 under the supporting action of the bearing 111, so that the table top 103 is gradually lifted. Referring to fig. 1 and 3, the table 103 is flipped a set angle along the AA axis relative to the floor 107. The second cylinder 120 is controlled to push and extend, the tooth block is meshed with the rack 118, and the supporting assembly 117 supports the table top 103 through the second cross bar 116. At this time, the test piece under a specific angle may be tested. Conventionally, the first oil cylinder 113 and the second oil cylinder 120 are controlled by a control program of a controller to extend and retract through electromagnetic valves and oil ways, so that the angle overturning of the table top 103 and the rigid connection of the rack 118 and the tooth sleeve 119 are completed. The inlet and return paths of the first cylinder 113 and the second cylinder 120 are provided with hydraulic check valves to ensure that sufficient pressure is applied to firmly pull the first and second cross bars 105, 116 and to ensure that the table top 103 is stable.
