In a preferred embodiment of the present invention, the clamping device comprises a first clamp 2, a second clamp 3 and a connecting pin 4. Wherein the first clamp 2 comprises a clamp 21 and the second clamp 3 comprises a clamp 31. The clamp 21 and the clamp 31 are arranged right and left, are U-shaped in cross section, and each comprise a base plate 21a and two clamping plates 21 b. The base plate 21a is vertically arranged, and the two clamping plates 21b are respectively formed by vertically extending the upper end and the lower end of the base plate 21a towards the same side.

The first clamp 2 further includes a grip 22, and the grip 22 is vertically fixed to the base 21a of the chuck 21.

The second clamp 3 also comprises a grip 32. One end of the grip 32 is fixed to the base plate 21a of the chuck 31, and the other end is inclined in a horizontal plane toward a side away from the first chuck 2, for example, at an angle of 45 °. Rubber sleeves 33 are fixedly sleeved on one ends of the holding rods 22 and 23 far away from the corresponding chucks.

The connecting pin 4 extends in the left-right direction. One end of the connecting pin 4 is pinned to the chuck 21, and the other end of the connecting pin 4 is pinned to the chuck 31.

For right-handed workers, the first clamp 2 is preferably arranged on the right side of the second clamp 3; for left-handed workers, the first clamp 2 is preferably arranged to the left of the second clamp 3.

Taking a right-handed worker as an example, the holding rod 22 is used as a main holding rod, namely, the grinding wheel is positioned on the right side; the grip 32 serves as a secondary grip. After the casting is clamped between the two clamping heads 22 and 32, the casting can be clamped by relatively rotating the two holding rods 22 and 23; when the casting needs to be released, the holding rods 22 and 23 are rotated to be coplanar.

In other embodiments, it is preferable that the clamping device further includes two stoppers 5 for restricting the relative movement of the connecting pin 4 and the corresponding collet from left to right.

Specifically, the limiting member 5 includes a pressing sleeve 51, an end cap 52 and a locking piece 53. The connecting pin 4 includes a pin 41 and caps 42 fixed to left and right ends of the pin 41. The left and right ends of the chucks 21, 31 are opened with pin holes 24 corresponding to the connecting pins 4. One end of the pressing sleeve 51 presses the column cap 42 on the bottom of the corresponding pin hole 24, and the other end of the pressing sleeve 51 is vertically fixed with the end cover 52. The end caps 52 are engaged with the left and right opposite ends of the chucks 21, 31. The left and right ends of the locking piece 53 are fixed perpendicularly to the end cap 52. The left and right ends of the locking piece 53 extend toward one side of the pressing sleeve 51 and are fixed to the corresponding chuck by the screw 7.

To facilitate the clamping of the casting 1 between the clamping plates of the clamping head, the inner walls of the clamping plates 21b may form a certain opening angle α, for example, 5 ° to 10 °.

In other embodiments, it is preferable that a rotating shaft 25 is fixed to a lower end of the chuck of the first chuck 2, and the rotating shaft 25 extends in the left-right direction. Correspondingly, a semicircular groove 60 is correspondingly formed on the frame 6 of the grinding machine on the grinding wheel side in a concave mode. When the casting grinding machine is used, the rotating shaft 25 can be positioned and supported in the groove 60, and then the casting 1 can be subjected to rotating grinding in a labor-saving mode.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
