Description

Technical Field

[0002] A clamping jaw is a mechanical device used to clamp a workpiece on a machine tool. The workpiece is clamped by utilizing the radial movement of the movable clamping jaws evenly distributed on the chuck, making it easier for the machine tool's machining tool to process the workpiece.

[0003] For example, a high-strength copper lathe clamping jaw with the authorization announcement number "CN217223633U" can adjust the length of the fixed block by assembling the fixed block when clamping workpieces of different lengths, so that the device clamps more stably and improves the applicability of the device. When the device adjusts the clamping jaw, the length of the clamping jaw is adjusted by transmission between the gear and the rack, but when clamping, the clamping jaw will clamp the workpiece under the action of hydraulic pressure, and the clamping jaw will be subjected to a large force. At the same time, the device is easily damaged by transmission between the gear and the rack, resulting in poor clamping effect of the device. At the same time, the device is easy to be damaged, which will make the device unable to adapt to high-intensity processing. Utility Model Content

[0021] Refer to the attached Figure 1-5 : The locking device 7 includes a card plate 701 and a short rod 705. The card plate 701 is movably connected to the surfaces of the two groups of short rods 705 through grooves provided on the surface, and the rotation centers of the short rods 705 on both sides are fixed. The card plate 701 is tightly pressed against the surface of the handle 704 through the grooves provided on the surface. The surface of the handle 704 is fixedly connected to one end of the two groups of short rods 705. The short rods 705 on both sides can fix the position and rotation center of the handle 704.

[0023] Working principle:

[0024] When the chuck is used, the base 1 is mounted to the surface of the chuck by means of the threaded plate 8 and bolts, so that one side of the threaded plate 8 is close to the center of the chuck.

[0025] Adjustment process:

[0026] The operator removes the base 1, and the operator turns the handle 704 so that the handle 704 can be rotated and unfolded. The operator pulls the handle 704 to pull the clamping plate 701 to move, so that the clamping plate 701 can push the round blocks 702 on both sides to move, so that the round blocks 702 on both sides can compress the first springs 703 on both sides, so that the clamping plate 701 can be pulled out, and the movement of the clamping plate 701 can drive the three groups of round rods 2 to move synchronously, so that the three groups of round rods 2 can no longer be clamped with the trapezoidal block 3, so that the position of the trapezoidal block 3 can be adjusted. After the adjustment is completed, according to the above operation, the three groups of round rods 2 can be clamped with the round holes 4 on the surface of the trapezoidal block 3 again.

[0027] Auxiliary locking process:

[0028] When adjusting the position of the trapezoidal block 3, (in Figure 2 (from the perspective of ) when the trapezoidal block 3 moves to the left, the circular hole 4 can continuously push the inclined block 603 to move, so that the inclined block 603 can continuously compress the second spring 604, so that the inclined block 603 can limit the trapezoidal block 3. When the trapezoidal block 3 needs to move in the opposite direction, the operator pulls the bent rod 601 so that the bent rod 601 can drive the inclined block 603 to move through the connecting rod 602, so that the inclined block 603 is retracted into the base 1, so that the trapezoidal block 3 can move.
