A beam with rolling and sliding rails

Abstract

The invention discloses a beam with a rolling guide track and a sliding guid track. The beam with the rolling guide track and the sliding guid track comprises a beam (1), a rolling line track(2) and a sliding hard track (3). According to the beam with the rolling guide track and the sliding guid track, two guide tracks of the rolling line track and the sliding hard track are respectively arranged on the beam, when rough milling is carried out, a light-load transverse motion device is controlled to stay at a side and be static, a heavy-load X lead screw assembly and a heavy-load X servo motor are controlled to drag a heavy-load transverse motion device to carry out transverse motion target heavy-load rough milling along an axis X on the beam, when fine milling is carried out, the heavy-load transverse motion device is controlled to stay at the side and be static, a light-load X lead screw assembly and a light-load X servo motor are controlled to drag the light-load transverse motion device to carry out transverse motion target light-load fine milling along the axis X on the beam. The technical scheme is applied, a one-drag-two numerical control milling machine is capable of being through rough processing and fine processing by one-time clamping, and the aims that the rough processing and the fine processing are compatible, cost is lowered, efficiency is improved, and processing accuracy is improved are achieved.

Description

technical field [0001] The invention relates to a beam member of a numerically controlled milling machine, specifically referring to two sets of rolling and sliding guide rails provided on the beam of a numerically controlled milling machine, respectively bearing and dragging two sets for high-speed fine milling and heavy-duty rough milling A type of lateral movement device with a beam that has two guide rails for rolling and sliding. Background technique [0002] The CNC milling machine is composed of a three-axis three-dimensional Cartesian coordinate motion device in the X direction, Y direction, and Z direction. The beam is a component used by the CNC engraving and milling machine tool to carry and drag the lateral motion device for lateral movement, that is, the X direction. The so-called lateral motion device consists of Z direction Skateboard pair, Z-direction screw pair, Z-direction servo motor, and spindle motor; the beam of some CNC milling machines only carries an...

Problems solved by technology

[0003] The two sets of load-carrying rails of the one-to-two crossbeam in the prior art are all one kind, that is, either the hard rail structure that is all sliding is called sliding hard rail, or the line rail structure that is all rolling is called rolling line rail; The rail is suitable for bearing the strong impact and vibration produced by heavy-duty rough milling, and the rolling line rail is suitable for high-speed precision fine milling. Since the two sets of bearing rails for the same beam are one type, it is difficult for one-to-two CNC milling machines to meet the requirements of one-time clamping. Rough and fine compatible processing requirements, that is, rough milling is efficient, fine milling is not precise, and fine milling is precise, but rough milling is not efficient. It is used for precision fine milling; for efficient heavy-duty rough milling, the one-to-two CNC milling machine with sliding hard rails is only used for heavy-duty rough milling. In addition, the workpiece after heavy-duty rough milling must be moved to the precision machining After the machine tool is clamped for the second time, the finishing milling process is performed. Repeatedly moving and clamping in this way is labor-intensive and time-consuming, resulting in high processing costs, low efficiency, and difficult to guarantee processing accuracy. The problems and deficiencies of high ranking, low efficiency and poor machining accuracy
