Embodiment Construction

[0034] The present invention is described in detail below in conjunction with accompanying drawing:

[0035] Universal precision CNC support column, mainly composed of replaceable support head 1, retractable protective cover 3, linear sliding bearing 4, limit sensor 5, mounting flange 6, support rod 7, outer cylinder liner 8, outer protective cover 9. Ball screw 10, ball screw nut 11, spline guide shaft 12, reducer 13, motor cabin seat 14, motor 15, numerical control module 16, electrical connector 17, and base 18.

[0036] The support rod 7 is located inside the outer cylinder sleeve 8, and can be stretched and contracted under the drive of the screw pair to form the linear motion part of the support column; the support rod 7 is a hollow structure, which is set on the outer layer of the ball screw 11, and the lower end surface is connected with the screw by the screw. The spline guide shaft 12 is connected, and is rigidly connected with the flange of the ball screw nut 11 by ...

Abstract

The invention discloses a universal precision numerical control support vertical column which mainly comprises a support rod, an outer cylinder sleeve, a lead screw pair, a speed reducer, a numerical control module, an electric plug connector and a base, wherein the outer cylinder sleeve is sleeved outside the support rod, the speed reducer is connected with a ball screw, the numerical control module is used for realizing a numerical control function of a motor, the electric plug connector is connected with the numerical control module, and the base is fixedly connected with the electric plug connector. The support rod is guided by a spline guide shaft, a guide groove in the inner wall of the outer cylinder sleeve and a linear sliding bearing, and the linear sliding bearing is mounted at the upper end of the inner wall of the outer cylinder sleeve. The universal precision numerical control support vertical column is convenient to mount and easy to operate, can be individually used, parts are supported and positioned in the machining and measuring process, the automation degree of the production process is improved, the universal precision numerical control support vertical column modularly designed is used for flexibly, intelligently and digitally supporting three-dimensional curved surface parts in the manufacturing process as a multipoint flexible fixture is mounted, and manufacturing cost and technical difficulty are reduced.

Description

technical field [0001] The invention relates to a support column whose height can be adjusted by numerical control. The invention belongs to the field of mechanical engineering. Background technique [0002] In the process of milling, drilling, scribing and assembly of large three-dimensional curved parts such as aircraft skins, train outer panels, and building exterior walls, special fixtures are required to absorb, support and position the parts. In the previous production process, each part required a set of special tooling, which was costly and required a large storage space. The multi-point flexible tooling can automatically arrange the required column position and adjust to the required height according to the size and geometric shape of the supported parts, instead of the traditional special tooling, support and fix large three-dimensional curved surface parts for measurement, drawing Line, edge milling, drilling and other operations, so as to realize the flexible, i...
