Heavy numerical control horizontal lathe tailstock capable of being adjusted within small distance and adjusting method

Abstract

The invention relates to the technical field of numerical control, and discloses a heavy numerical control horizontal lathe tailstock capable of being adjusted within a small distance, the heavy numerical control horizontal lathe tailstock comprises a base, a barrel, a screw rod, a transmission gear, a first rocking wheel, a limiting rod and a fine adjustment assembly, the top end of the base is fixedly connected with the barrel, the inner wall of the barrel is movably connected with the screw rod, and the outer wall of the screw rod is located on the left side of the barrel and fixedly connected with the transmission gear. According to the heavy numerical control horizontal lathe tailstock capable of being adjusted within the small distance and the adjusting method, the first rocking wheel is rocked to drive the screw rod to rotate, so that the tailstock is preliminarily adjusted, then the position of the limiting rod is adjusted to adjust the position of a clamping block, thus the clamping block is selected to be clamped with one of a first limiting block, a second limiting block and a third limiting block, then a power gear is selected to be meshed with one of a single-fluted disc, a double-fluted disc and a four-fluted disc, and then a second rocking wheel is used for finely adjusting the position of the screw rod until the position reaches a proper position.

Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a heavy-duty numerical control horizontal lathe tailstock which can be adjusted within a small distance and an adjustment method. Background technique [0002] There are three main functions of the CNC lathe tailstock: use the eccentric shaft of the tailstock car, adjust the lathe precision and assist drilling through the tailstock during installation. [0003] The existing method of using the tailstock of the lathe is to directly rotate the screw through the rocking wheel, and then drive the movement of the thimble through the rotation of the screw. Adjust the moving distance of the thimble within a certain distance. When processing some small workpieces, the locking will not be stable, and it will easily cause scratches on the surface of the workpiece, which will greatly reduce the machining accuracy of the machine tool. [0004] On the premise that the tailstock its...

[0003] The existing method of using the tailstock of the lathe is to directly rotate the screw through the rocking wheel, and then drive the movement of the thimble through the rotation of the screw. Adjust the moving distance of the thimble within a certain distance. When processing some small workpieces, the locking will not be stable, and it will easily cause scratches on the surface of the workpiece, which will greatly reduce the machining accuracy of the machine tool.
