A cutter head for CNC machine tool cutting

Abstract

This invention relates to the field of CNC machine tool technology, and in particular to a tool disc for CNC machine tool cutting, comprising a mounting frame and a CNC machine tool body. The mounting frame is fixedly connected to the upper end of the CNC machine tool body, and the mounting frame is threadedly connected to a frame via multiple sets of bolts. The frame is slidably connected to a sliding plate via grooves in its inner wall, and a square plate is fixedly connected to the upper end of the sliding plate. Through the cooperation of a transmission control device, an adjustment device, a turntable, and a ring, the operator drives the turntable to rotate via a handle, causing the grooves on the turntable surface to continuously push a semi-circular block to move, allowing the semi-circular block to continuously compress and release a first spring. This allows the through holes on the turntable surface to align with the tool to be removed and replaced. Based on the above operation, the tool is no longer clamped, allowing for rapid individual tool adjustment. The ability to pick up and put away a group of tools makes the tool disc more convenient to use.

[0052] The control cylinder 802 is operated so that the telescopic end of the cylinder 802 is extended to drive the trapezoidal block 803 to move downward, so that the trapezoidal block 803 can push the inclined surface of the push block 806 through the inclined surface provided on the outer wall, so that the push block 806 can slide on the surface of the horizontal column 808, so that the push block 806 can compress the second spring 809, and the push block 806 can drive the top block 807 to press against the outer wall of the annular plate 20, so that the positions of the annular plate 20 and the turntable 21 are fixed, and the control motor 13 is operated so that the output shaft of the motor 13 rotates to drive the sleeve 12 to rotate, so that the sleeve 12 can drive the rotating shaft 5 to rotate, so that the rotating shaft 5 can drive the through-hole plate 908 to rotate, so that the through-hole plate 908 can drive the connecting column 4 to rotate synchronously, so that the connecting column 4 can drive the third horizontal plate 205 to rotate. , so that the third horizontal plate 205 can drive the round rod 203 to move synchronously, so that the round rod 203 can drive the semicircular block 204 to move synchronously, so that the semicircular block 204 can continuously slide in the groove on the surface of the turntable 21, so that the first spring 202 is continuously compressed and released, and the motor 13 drives the connecting column 4 to rotate, so that the connecting column 4 and the through-hole plate 908 drive multiple sets of tools to move. When the required tool moves to align with the through-hole on the surface of the turntable 21, the motor 13 is stopped. According to the above operation, the multiple sets of arc blocks 902 are no longer pressed against the tool surface. Under the action of gravity, the tool can fall out of the through-hole on the surface of the turntable 21. The operator can take out the tool. According to the above operation, the top block 807 is separated from the annular plate 20, and the multiple sets of arc blocks 902 are pressed against the tool again.

[0053] Individual tool change process:

[0054] The operator drives the turntable 21 to rotate through the handle 201, so that the groove on the surface of the turntable 21 can continuously push the semicircular block 204 to move, so that the semicircular block 204 can continuously compress and release the first spring 202, so that the through hole on the surface of the turntable 21 can be aligned with the tool to be taken out and replaced. According to the above operation, the tool is no longer pressed tightly, so that the tool can be quickly adjusted individually.

[0055] Although the invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
