Lifting device for repairing numerically-controlled machine tool

Abstract

The invention provides a lifting device for repairing a numerically-controlled machine tool. The lifting device comprises two movable plates; four support rods in rectangular distribution are symmetrically and fixedly mounted on the tops of the movable plates; the same support plate is fixedly mounted at the top ends of the four support rods; a motor frame is fixedly mounted on the top of the support plate; a motor is fixedly mounted on the top of the motor frame; the same lifting rod is rotatably mounted among the movable plates and the support plate; the top end of the lifting rod is fixedlyconnected with the output shaft of the motor; a threaded pipe is fixedly arranged on the outer side of the lifting rod in a sleeving manner; two lifting plates in sliding fit with the four support rods fixedly sleeve the outer side of the threaded pipe; and elevating plates are fixedly mounted on two mutually closed sides of the two lifting plates. The lifting device is convenient to use and highin stability and safety and can prevent a risen numerically-controlled machine tool from falling off suddenly while lifting the numerically-controlled machine tool.

Description

technical field [0001] The invention relates to the technical field of maintenance of numerical control machine tools, in particular to a lifting device for maintenance of numerical control machine tools. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] After retrieval, the application number is: 201820620745.1 A lifting device for CNC machine tool maintenance disclosed, includi...
