Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tool equipment, in particular to a lifting and adjusting platform for a numerical control lathe. Background Art

[0002] A numerical control lathe is a widely used numerical control machine tool. During the machining process, adjusting the height of the workbench is crucial for ensuring machining accuracy and efficiency.

[0003] However, traditional lifting and adjustment mostly rely on a hydraulic system. Although this method is simple and easy to operate, problems such as slower or faster response speeds may occur after long-term use, resulting in workpiece position deviation and affecting machining quality. At the same time, vibrations are generated when machining parts on the numerical control machine tool, which may accelerate the wear of the device parts and reduce the service life of the device. Also, when machining workpieces on the numerical control machine tool, the problem of unstable workpiece fixation will affect the machining accuracy.

[0004] A lifting and adjusting platform for a numerical control lathe disclosed in the publication number CN215788163U. Although the utility model relates to the technical field of numerical control machine tool equipment, in particular to a lifting and adjusting platform for a numerical control lathe, including a chassis, a weighing frame is arranged on the end face of the chassis, through holes are opened at the four corners of the end face of the chassis, a chute is opened on the end face of the chassis, a convex shaft is installed inside the chute, a hydraulic push rod is fixedly connected to the inner side wall of the weighing frame, one end of the hydraulic push rod is connected to one end of an intermediate rod, the other end of the intermediate rod is connected to an eccentric sprocket, and the eccentric shaft hole of the eccentric sprocket is rotatably connected to the convex shaft. The utility model transfers the linear displacement of the hydraulic push rod into the movement of the eccentric sprocket rotating around the convex column through the transmission of motion between the sprocket and the chain, eliminating the error of the linear displacement of the hydraulic push rod on the overall lifting and enhancing the accuracy of lifting. Moreover, with the threaded screw connection, it has a self-locking effect, ensuring that the device will not suddenly collapse after unloading, eliminating potential safety hazards to a certain extent.

[0005] Although the above patent achieves converting the linear displacement of the hydraulic push rod into the movement of the eccentric sprocket rotating around the convex column by using a hydraulic device to drive the hydraulic push rod through the special positions of the central rod and the eccentric sprocket, eliminating the error of the linear displacement of the hydraulic push rod on the overall lifting and enhancing the accuracy of lifting; however, this device lacks a shock absorption mechanism and a fixing component, cannot improve the stability of the device during machining, and cannot reduce the impact of vibrations on machining accuracy.
