1. the workpiece is supported at multiple points through the multiple groups of displacement adjusting mechanisms, the supporting plates of the multiple groups of displacement adjusting mechanisms share stress, the position of the workpiece is adjusted together, and a displacement adjusting device special for large heavy workpieces does not need to be produced, so that the production cost is reduced.
2. Through the setting of first detection piece, detect the work piece position, and then judge whether the work piece adjusts the required position, improve the accuracy nature of displacement adjustment.
Through the setting of second detection piece, third detection piece, improve the precision of displacement adjustment. Specifically, when the speeds of the first driving member and the second driving member for driving the sliding plate and the supporting plate are set, errors are inevitably generated between the set speed and the actual speed, and when a single set of displacement adjusting mechanism is used, the errors do not affect the movement of the workpiece. But when setting up multiunit displacement adjustment mechanism simultaneously, will produce the multiple spot error, when a plurality of backup pads motion is asynchronous promptly, lead to the backup pad to drive the accuracy nature reduction that the work piece removed, can produce relative motion even between partial backup pad and the work piece.
The sliding of the sliding plate is taken as an example, if the sliding speeds of the sliding plates of the multiple groups of displacement adjusting mechanisms or the sliding distances in the same time are different, this shows that the synchronism of the sliding plate movement of the multiple groups of displacement adjusting mechanisms is poor, then the synchronism of the sliding plate driving the movement of the supporting plate is poor, therefore, the synchronism of the movement of the multiple sliding plates is detected (correspondingly) through the second detecting piece, the third detecting piece is used for detecting the synchronism of the vertical movement of the multiple supporting plates, the movement synchronism of the sliding plate or the supporting plate is judged, and then the first driving piece or the second driving piece is adaptively adjusted, so that the synchronism of the movement of the workpieces driven by the multiple supporting plates is ensured, and the accuracy of the movement of the workpieces driven by the supporting plates is improved.

In the process, the two first lateral support rods 3 are respectively located on the side of the workpiece 1A and the side of the workpiece B, for example, the workpiece 1 moves towards the side a, the first lateral support rod 3 on the side a is pushed to slide towards the first piston barrel 6, the first piston 5 on the side a pushes hydraulic oil in the first piston barrel 6 to enter the first piston barrel 6 on the side B through the first oil inlet pipe 7, and the first piston 5 on the side B pushes the first lateral support rod 3 to slide and abut against the side surface of the workpiece 1, namely, in the process of displacement of the workpiece 1X, the two first lateral support rods 3 can slide along with the first lateral support rod, so that the workpiece 1 is always supported, and the stability of displacement of the workpiece 1 is improved. The flow detector detects the flowing conditions of the hydraulic oil in the two corresponding first piston barrels 6 in the X-direction displacement process of the workpiece 1, and the accuracy of the whole X-direction displacement of the workpiece 1 can be judged in an auxiliary manner by comparing the flowing conditions of the hydraulic oil in the multiple groups of corresponding first piston barrels 6.
Accordingly, when the workpiece 1 is transported out while being displaced in the Y direction, the valve in the first oil feed pipe 7 is closed, the valve in the second oil feed pipe 21 is opened, and the oil pump is started. The first lateral supporting rod 3 is fixed and used for limiting the workpiece 1 in the X direction, and deviation of the workpiece 1 in the displacement process is avoided. In the process, the oil pump is used for pumping the hydraulic oil in the two corresponding second piston barrels 20, namely the hydraulic oil in one of the second piston barrels 20 is pumped into the other second piston barrel 20, the second lateral support rod 19 located on one side of the workpiece 1 slides into the second piston barrel 20, under the action of the hydraulic oil, the second lateral support rod 19 located on the other side of the workpiece 1 slides out of the second piston barrel 20, in the Y-direction displacement process of the workpiece 1, the two second lateral support rods 19 can slide along with the second lateral support rod 19, the workpiece 1 is always supported, and the displacement stability of the workpiece 1 is improved. Meanwhile, because the second lateral supporting rods 19 are obliquely arranged, the free ends of the second lateral supporting rods 19 on the two positioning plates 2 are far away from or close to each other in the sliding process, when the second lateral supporting rods 19 on the two positioning plates 2 are far away from each other, the distance can be used for the workpiece 1 to pass through, and the workpiece 1 can not be obstructed from being transported out from the direction.
Example 4
The present embodiment further includes a first locking member for locking the first lateral support bar 3 and a second locking member for locking the second lateral support bar 19, based on embodiment 1 or embodiment 3, as shown in fig. 4. The first locking part comprises a first rack 9 fixed on the first lateral supporting rod 3, a first limiting strip 10 (in the direction shown in fig. 4, the vertical direction is a direction perpendicular to the paper surface) which is used for being clamped between adjacent teeth of the first rack 9 is vertically and slidably connected to the positioning plate 2, and an air cylinder used for driving the first limiting strip 10 to slide is installed on the positioning plate 2; the second locking piece comprises a second rack fixed on the second lateral supporting rod 19, a second limiting strip used for being clamped between adjacent teeth of the second rack is connected to the positioning plate 2 in a vertical sliding mode, and an air cylinder used for driving the second limiting strip to slide is mounted on the positioning plate 2.
During the specific use, work piece 1 is when X to the displacement, and second lateral support pole 19 provides the limiting displacement to work piece 1, consequently locks second lateral support pole 19 through the second locking piece, avoids second lateral support pole 19 to slide, and is specific, inserts between the adjacent tooth of second rack through the spacing strip of second, realizes the locking to the second rack, and then realizes the locking to second lateral support pole 19. Correspondingly, when the workpiece 1 is displaced in the Y direction, the first lateral support rod 3 provides a limiting effect on the workpiece 1, so that the first lateral support rod 3 is locked by the first locking piece, specifically, the first limiting strip 10 is inserted between adjacent teeth of the first rack 9, and the first lateral support rod 3 is locked.
