Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a lifting device for numerically controlled lathes. Background Art

[0002] CNC lathe is a high-precision, high-efficiency automated machine tool, equipped with a multi-station turret or a power turret. The machine tool has a wide range of processing performance, and can process complex workpieces such as straight cylinders, oblique cylinders, arcs, various threads, grooves, worms, etc. It has various compensation functions of linear interpolation and circular interpolation, and has played a good economic effect in the mass production of complex parts. CNC lathe is also one of the most widely used CNC machine tools. It is mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary cone angles, complex rotary inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring. When adjusting the height of the CNC lathe, it is usually supported by an auxiliary lifting device, so that the CNC lathe can be adjusted in height according to the usage, which is very convenient;

[0003] According to the "A CNC Lathe Lifting Device" disclosed in Chinese Patent Publication No. CN215432506U, through the setting of the support assembly, when the CNC lathe installed on the top surface of the support table is adjusted to a suitable height, the pull plate can be pushed inward to drive the positioning plate to slide inside the rectangular cavity through two connecting rods, so that when it slides in the direction of the corresponding limit block, the positioning groove opened inside is fitted with the corresponding limit convex plate to complete the positioning of the limit block. While completing the height adjustment, effective support can be achieved through the cooperation of the two limit rods and the positioning blocks and limit blocks set at both ends. The support is more stable and the support strength of the scissor-type lifting arms on both sides and the corresponding hydraulic columns is reduced, so that the safety and service life of the device are improved. The two hydraulic columns are vertically arranged on the inner side of the corresponding scissor-type lifting arms through the positioning sheets, and both ends are rotatably connected. When the scissor-type lifting arms are extended and retracted by the lifting and lowering of the hydraulic columns, the hydraulic rod can be lifted vertically to reduce the bearing capacity of the connection between the hydraulic column and the hydraulic rod, thereby avoiding damage to the hydraulic column.

[0004] However, the above device has the problem that the lifting process is not stable enough during use, which makes it inconvenient to use. Utility Model Content
