Abstract

A clamping device is described for clamping a log such as a log of wound material.

Claims

1. A clamping device for clamping a log, the clamping device comprising:

a frame;

a supporting arm fixed on the frame for supporting the log;

a pair of clamps for clamping the log; and

a base plate for carrying the pair of clamps, the pair of clamps moveably disposed on the base plate for changing the distance between the clamps, and the base plate moveably disposed on the frame for changing the distance between the clamps and the supporting arm.

2. The clamping device of claim 1 further comprising at least one post, the base plate moveably connected to the at least one post.

3. The clamping device of claim 2, wherein the at least one post is a screw, the base plate is threadedly engaged with the at least one post, and the base plate moves relative to the frame via the rotation of the at least one post.

4. The clamping device of claim 1 further comprising a pair of cradles moveably disposed on the base plate, the pair of clamps being connected to the pair of the cradles respectively.

5. The clamping device of claim 4, wherein a follower is rotatably formed on each cradle, a profile is fixed on the frame corresponding to the follower, the profile has a surface on which the follower moves along to change the distance between the cradles.

6. The clamping device of claim 5, wherein the follower on one cradle and a corresponding profile are symmetrical with respect to the follower on another cradle and another corresponding profile relative to a vertical plane parallel to the longitudinal axis of the log and passing through a central region of the clamping device.

7. The clamping device of claim 4, wherein one clamp is fixed onto one cradle, and another clamp is pivotably connected to another cradle and wherein the another clamp is capable of rotating between a clamping position and an open position.

8. The clamping device of claim 4, wherein a cradle actuator is connected to each cradle for changing the distance between the cradles.

9. A clamping device for clamping a log, the log having a circumferential surface, the clamping device comprising:

a frame;

a supporting arm fixed on the frame for holding a bottom of the circumferential surface of the log;

at least one post;

a base plate moveably formed on the at least one post to adjust a vertical position thereof; and

at least one pair of clamps for symmetrically clamping opposite sides of the circumferential surface of the log, the at least one pair of clamps moveably disposed on the base plate to adjust a horizontal position thereof.

10. The clamping device of claim 9 further comprising at least one pair of cradles moveably disposed on the base plate, wherein each clamp is connected to a corresponding cradle.

11. The clamping device of claim 10, wherein a rail and a track are formed between the cradle and the base plate to provide a slidable movement between the cradle and the base plate.

12. The clamping device of claim 11, wherein a follower is rotatably formed on each cradle, a profile is fixed on the frame corresponding to the follower, the profile has a surface on which the follower moves along to change the position of the cradle on the base plate, thereby changing the position of a corresponding clamp on the base plate.

13. The clamping device of claim 11, wherein a cradle actuator is connected to each cradle for changing the horizontal position of the cradle on the base plate.

14. The clamping device of claim 10, wherein one of the at least one pair of clamps is fixed onto one of the at least one pair of cradles, and another of the at least one pair of clamps is pivotably connected to another of the at least one pair of cradles and capable of rotating between a clamping position and an open position.

15. The cutting machine of claim 14 further comprising a motor and an actuator connecting the another of the at least one pair of clamps, the actuator transferring power provided by the motor to the another of the at least one pair of clamps to drive the rotation of the another of the at least one pair clamps between the clamping position and the open position.

16. The cutting machine of claim 15, wherein the motor is fixed on the frame, and the actuator is positioned beneath the base plate, and penetrates through the base plate to connect the another of the at least one pair clamps.

17. The cutting machine of claim 9, wherein the at least one post is a screw, the base plate is threadedly engaged with the at least one post, and the base plate moves relative to the frame via the rotation of the at least one post to change the vertical position of the base plate, thereby changing the vertical position of the at least one pair of clamps.

18. The cutting machine of claim 17 further comprising a motor for driving the at least one post.

19. The clamping device of claim 18, wherein the motor is fixed on the frame.
