Problems solved by technology

At present, in the CNC upgrading and transformation of ordinary lathes, the connection method between the servo motor assembly and the spline shaft or ball screw is based on accurate measurement and calculation, and then the mounting plate is installed at the position of the original tool post reducer. The servo motor assembly is installed on the mounting plate. This servo motor connection method has certain shortcomings, because the installation position of the servo motor assembly needs to be punched on the bed elevation of the lathe, and the mounting plate There are installation errors in the position. The determination of the installation position of the servo motor assembly on the mounting plate has many variable factors, such as the processing accuracy of the transmission gear,

Abstract

The invention discloses a vertical type lathe servo motor assembly connecting device and a connecting method thereof. The connecting device comprises a rack, a transmission shaft, a servo motor assembly, a mounting plate and an adjustment plate. The transmission shaft is connected with a tool holder of a vertical type lathe and transmits feeding power for the tool holder. The mounting plate is fixedly mounted at the transmission shaft driving end of the rack. The servo motor assembly is fixed to the adjustment plate. An output shaft of the servo motor assembly is in transmission connection with the transmission shaft through a gear. The mounting plate and the adjustment plate are each provided with a through hole, wherein the through holes allow the output shaft of the servo motor assemblyto penetrate through. The mounting plate and the adjustment plate are fixedly connected through bolts arranged in mounting holes of the adjustment plate. Each mounting hole is a long hole. Two locating pins are arranged between the adjustment plate and the mounting plate. The connecting device and the connecting method thereof are simple in structure and convenient to mount; the workload of refitting the vertical type lathe into a numerically-controlled machine tool is greatly reduced; the transmission precision of the numerically-controlled machine tool can be guaranteed; the numerically-controlled machine tool obtained after refitting and upgrading can operate steadily and is low in noise; and the quality of machined products can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vertical lathes, and relates to a connecting device for a servo motor assembly of a vertical lathe and a connecting method thereof. Background technique [0002] The development of the manufacturing industry requires higher control precision for processing and manufacturing equipment; the development of electronic technology has made the application of CNC lathes and semi-NC lathes (PLC-controlled servo-driven lathes) widely popularized. In traditional ordinary lathes, the main movement generally adopts a multi-axis product step change mechanism, the system structure is complex, and the transmission chain is long, resulting in low transmission accuracy and poor dynamic performance. Modern CNC lathes mostly use servo motors to drive the rotation of the spindle, and the transmission is realized by the servo motor plus a few stages of variable speed. This transmission mode has a short transmission chain, not...
