Description

Technical Field

[0001] The utility model relates to the technical field of numerical control equipment, and particularly relates to a four-axis cam turntable. Background Technique

[0002] A numerical control machine tool is short for a numerically controlled machine tool, which is an automated machine tool equipped with a program control system. Turntables are commonly used on numerical control machine tools and are used as the fourth axis of the numerical control machine tool to meet the needs of the numerical control machine tool.

[0003] Most existing numerical control machine tools use three axes. Sometimes, they cannot complete the machining tasks at one time, and the machining efficiency is relatively low, and multiple clamping operations are required.

[0004] In order to overcome the above defects, there is a roller cam four-axis structure in the prior art 1 (a Chinese patent with the publication number CN218874441U and the application date of November 28, 2022). The four-axis structure of this utility model can complete the tasks that cannot be completed by a three-axis machine tool at one time. The fourth axis can rotate to enable multi-sided machining of the workpiece, greatly improving the machining efficiency and reducing the number of clamping operations; the surface of the camshaft is in line contact with the surface of the roller bearing of the turret to drive the turntable to rotate. The camshaft and the turret use the internal roller bearing to transmit torque during the rotation process. Such a working principle ensures zero backlash, excellent working accuracy and working efficiency, and effectively avoids the wear of internal parts, providing a long-lasting high-precision working state.

[0005] There is also a prior patent 2 (a Chinese patent with the publication number CN115647839A and the application date of October 10, 2022), a novel end-face roller cam four-axis turntable. The turntable bearing includes an inner ring part and an outer ring part. The inner ring part is fixedly connected to the main shaft part, and the outer ring part is connected to the turntable part. Therefore, the inner ring is fixed and the outer ring rotates. Under the action of the same force, the force arm of the outer ring part is larger, so the generated torque is larger, which is easier to push the outer ring part to rotate, thereby improving the transmission rigidity.

[0006] The four-axis structures of the prior art 1 and the prior art 2 can complete the tasks that cannot be completed by a three-axis machine tool at one time. However, during the use process, it is not convenient to lubricate the inside of the four-axis cam turntable, so that the inside of the turntable is worn, affecting the service life of the turntable.
