Middle drive slanted kicking block pull rod 16 moves, so that slanted kicking block pull rod 16 drives slanted kicking block to be moved along Z-direction.
Its operation principle is as follows：
1st, toward placement workpiece to be processed 2 on clamping device 1：
Control connecting rod 122 drives the clamping jaw 121 of U-shaped briquetting up to stir, and it is U-shaped fixed that workpiece 2 is loaded into along X-direction
In the slot 110 of position, U-shaped locating slot 110 fixes workpiece 2 along Y direction.
2nd, the workpiece 2 being loaded into U-shaped locating slot 110 is processed：
Control connecting rod 122 drives clamping jaw 121 to rotate down, and clamping jaw 121 is made to be pressed from Z-direction in the surface of workpiece 2；
And the second cylinder is drivingly connected block 16 and declines, so that link block 16 is pressed on a side of workpiece 2 as positioning side, it is U-shaped
Locating slot 110 fixes workpiece 2 along Y direction, and bulb plunger is pressed in workpiece 2 from X-direction compared with the another of link block 16
A side is pushed workpiece 2 to positioning side and is fixed, and cylinder 14 is driven slanted kicking block and rises, until the inclined-plane of slanted kicking block and workpiece 2
Corner abuts, and so as to withstand workpiece 2, workpiece 2 is made to remain push-tight power in the X-axis direction, to avoid workpiece 2 in process
In toward where bulb plunger one side retreat so that workpiece 2 is closely locked in U-shaped locating slot 110.In some preferred embodiments
In, 14 power output of cylinder is maintained at 7-8KG, and workpiece 2 can be made to reach optimal locating effect, avoids workpiece 2 in process,
Because bulb plunger floats and then influences processing effect back and forth.
3rd, workpiece 2 is discharged after machining：
The clamping jaw of the control U-shaped briquetting of connecting rod band stirs upwards, to unclamp the clamping to 2 surface of workpiece.Second cylinder drives
Dynamic link block 16 rises, so that link block 16 unclamps the pressing that side is positioned to workpiece 2, meanwhile, cylinder 14 is driven under slanted kicking block
Drop, so that the inclined-plane of slanted kicking block reduces contact area with the corner of workpiece 2 or do not contact, also, bulb plunger retreats, so as to
Workpiece 2 is taken out out of U-shaped locating slot 110 convenient for manipulator.
Therefore, clamping device 1 provided in this embodiment can combine U-shaped locating slot by clamp system 13 and hold-down mechanism 12
110, clamping force can be applied to workpieces processing 2 from multiple directions, and then workpieces processing 2 is lock onto in U-shaped locating slot 110, it keeps away
Exempt from workpiece 2 to move in process, improve processing efficiency and product quality.
