Slot 1330 is put, i.e. one end of slanted kicking block pull rod 16 is fixed in the guide hole at 14 top of cylinder, and is passed through in air cylinder fixed plate 15
Perforation, and then the other end is inserted in the storage tank 1330 of the bottom of slanted kicking block, so that process of the cylinder 14 in movement
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.
In addition, the utility model also provides a kind of numerically controlled lathe, including main shaft and turning attachment, the structure of main shaft with it is existing
Technology is similar, and turning attachment is the turning attachment of above-described embodiment, and concrete structure no longer specifically repeats herein.
It is different from the prior art, the clamping device and numerically controlled lathe provided by the utility model for preventing workpiece shift,
Middle clamping device includes bearing base, jig main body, hold-down mechanism and clamp system, and jig main body is arranged on bearing base,
And jig main body is provided with U-shaped locating slot, U-shaped locating slot allows workpiece to load along the first direction, and along perpendicular to first direction
Second direction to workpiece;Hold-down mechanism is compressed along perpendicular to first direction and the third direction of second direction positioned at U-shaped
Workpiece surface in locating slot, clamp system along the first direction applies workpiece shifts trend opposite effect with it, so that
Workpiece is fitted closely in U-shaped locating slot.Therefore, the clamping device of the utility model can be U-shaped by what is set on jig main body
Locating slot, hold-down mechanism and clamp system position workpiece from multiple directions, so as to can ensure that workpiece in process
It does not shift, improves processing efficiency and product quality.
Based on this, described above it does not limit the scope of the patent of the present invention, every to be said using the utility model
The mutual knot of technical characteristic between the equivalent structure or equivalent flow shift that bright book and accompanying drawing content are made, such as each embodiment
It closes, is directly or indirectly used in other related technical areas, is similarly included in the scope of patent protection of the utility model
It is interior.
