One end of the connecting plate 60 is connected to the upper surface 11 of the rotary driving member 10, and the other end of the connecting plate 60 is connected to the moving end of the processing device, which can drive the connecting plate 60 and the rotary driving member 10 to move. The machining device includes, but is not limited to, a CNC (machining center), a machine tool.

The clamping device 100 further includes a fixing block 70. The fixing block 70 has a substantially rectangular shape. The opposite sides of the fixed block 70 are respectively connected with the clamping driving member 20 and the rotary driving member 10, so that the rotary driving member 10 more stably drives the clamping driving member 20 to rotate.

The clamp driving member 20 is a parallel clamp cylinder (double acting cylinder). The clamp drive member 20 has a power end on each of opposite sides.

The positioning member 30 includes two positioning posts 31 and two positioning pins 32 disposed on the bottom surface 22 of the clamping driving member 20. Two reference column 31 and two locating pin 32 are mouth shape and distribute and parallel arrangement each other, and two reference column 31 and two locating pin 32 cooperate each other and insert and establish in order to fix a position the work piece in the work piece.

In the present embodiment, the parallelism of the two positioning columns 31 and the two positioning pins 32 is less than 0.05 mm. In the parallelism value, the positioned workpiece is vertical to the positioning column 31 and the positioning pin 32, the clamping device 100 can horizontally clamp the workpiece and accurately place the workpiece on a machining station, and the problem that the workpiece is obliquely clamped by the clamping device 100 and deviates from the machining station after the workpiece is placed can be effectively avoided.

In this embodiment, the sensing probe 50 is an edge finder.

The edge finder is a detection tool for accurately determining the central position of a workpiece to be processed in the numerical control processing. The edge finder has the working principle that one end of an X-axis is selected to be zero, the other end of the X-axis is selected to obtain a numerical value, half of the numerical value is taken as the midpoint of the X-axis, then the midpoint of the Y-axis is determined according to the same method, and finally the center of an XY plane is determined according to the midpoint of the X-axis and the midpoint of the Y-axis, wherein the center is a moving reference point.

In the application, the sensing probe 50 firstly carries out edge finding and positioning on a standard part placed at a workpiece placing position, and determines a moving reference point of the standard part; then, placing the workpiece on the standard part; then, the clamping device 100 moves to a position right above the reference point for moving, and clamps and positions the workpiece on the placement position by the cooperation of the clamping driving member 20 and the positioning member 30.

It will be appreciated that in use, the standard component may be omitted and the sensing probe 50 may be used to locate the workpiece directly at the workpiece placement location for precise clamping of the workpiece.

The implementation process of the embodiment is as follows:

mounting the clamping device 100 on the moving end of the processing device;

the standard part placed at the workpiece placing position is subjected to edge searching and positioning through the sensing probe 50, and a moving reference point of the standard part is determined; after determining to remove the fiducial, the selection of whether to disassemble the sensing probe 50 can be made as desired.

Placing the workpiece on the standard part;

the moving end of the processing device controls the clamping device 100 to move right above the moving reference point and move towards the workpiece, and in the moving process, the positioning column 31 and the positioning pin 32 are matched with each other and inserted into the workpiece to position the workpiece; then, the clamping driving member 20 drives the two clamping members 40 to approach each other and clamp the workpiece;

the moving end of the processing device controls the clamping device 100 to move to the processing station for processing. It is understood that before the workpiece is placed at the processing station, the rotation of the clamping drive member 20 can be controlled by the rotation drive member 10 to rotate the workpiece to a preset angle according to actual needs.

The clamping device 100 of the application firstly finds the edge of the workpiece through the sensing probe 50 before clamping the workpiece, then the clamping device 100 moves to the upper part of the workpiece placing position and clamps the workpiece after positioning the workpiece through the positioning part 30, and the workpiece can be rotated to a preset angle according to the processing requirement. Compared with the prior art, the clamping device 100 can accurately clamp the workpiece, can rotate the workpiece as required, is simple to operate, has various functions, and can meet diversified operation requirements.
