Detailed Description
Referring to fig. 1, the multi-position bolt mechanism of the invention comprises at least two or more than two parallel tensioning devices 7, and a group of tensioning units is formed by a plurality of tensioning devices, such as 2 to 20 or more, wherein the front end of each tensioning device is provided with a tensioning rod positioning and locking mechanism 11, a central axis of each tensioning rod positioning and locking mechanism is provided with a tensioning rod positioning hole, a bolt hole is vertically arranged in the horizontal direction of the corresponding mounting positioning hole, a bolt 5 is arranged in the bolt hole and can horizontally move along the hole, two connected but caliber-different double-position rod holes 9 are formed in the bolt 5, and the double-position rod holes are correspondingly matched with the tensioning rod locking positions. The plugboards 5 in the two adjacent tension rod positioning and locking mechanisms in the tension set are connected in a point or surface contact mode to form a linkage plugboard group. In this embodiment, a screw hole is formed in an end face of one side of the plugboard, a round head ejector rod or an ejector rod with balls is arranged in the screw hole and corresponds to an end face of an adjacent plugboard, and the plugboard groups are mutually pushed to realize synchronization when moving horizontally and laterally. The tensioning bench is synchronously locked or unlocked by the plugboard group. And when the tensioning cylinder feeds, stretches and withdraws, adjacent plugboards are contacted but do not interfere with each other. And the two ends of the tensioning unit are respectively provided with an A action oil cylinder 1 and a B action oil cylinder 8, wherein the rod end of the A action oil cylinder corresponds to one side of a large hole site of the plugboard group, and the rod end of the B action oil cylinder corresponds to one side of a small hole site of the plugboard group, namely a locking position.
The rod ends of the action oil cylinder A and the action oil cylinder B are also provided with oil cylinder push heads 3, and the oil cylinder push heads are connected with corresponding plugboards.
Figure 2 is a schematic view of a dual bit shank hole in a card. In the figure, the two-position rod hole is provided with two rod positions with different calibers, wherein the small caliber side is a locking position.
When the hydraulic locking device works, the A action oil cylinder 1 is in a piston rod extending state, the B action oil cylinder 8 is in a piston rod retracting state, the tension rod 6 passes through a large-caliber hole site of the plugboard 5 and enters a tension locking hole in the tension rod positioning locking mechanism, during locking operation, the pressure of a rod cavity and a rodless cavity of the A action oil cylinder 1 is balanced, the position of the piston rod is in a floating state, the piston rod of the B action oil cylinder 8 extends out to drive the oil cylinder push head 3 to push the plugboard group to synchronously displace, and the tension rod 6 enters a locking position, as shown in a state of fig. 1. During unlocking operation, the pressure of the rod cavity and the rodless cavity of the action oil cylinder 8 is balanced, the position of the piston rod is in a floating state, the piston rod of the action oil cylinder 1 extends out to drive the oil cylinder push head 3 to push the plugboard group to synchronously displace, and the tension rod 6 enters an unlocking position, namely a large-aperture position.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
