High-precision machining device and control method thereof

Abstract

The invention discloses a high-precision machining device. The technical scheme of the invention has the key points that the high-precision machining device comprises a machine tool body, at least one tool clamp arranged on the machine tool body and used for installing a tool, a workbench and a tray used for supporting a workpiece; the tray is clamped on the workbench in the machining process; the tool clamp can move along a first linear axis, a second linear axis and a third linear axis which are perpendicular to one another; the workbench comprises a machining region and a preparation region; the workbench is provided with two parallel first sliding rails; the tray enables the workpiece to move to the machining region from the preparation region and return through the first sliding rails; the tool clamp is provided with a connecting piece; the tray is provided with a connecting matching piece adaptive to the connecting piece; and the workbench is provided with a positioning device. The invention provides the machining device which improves the positioning precision of an air compressor shell, guarantees compression on the air compressor shell and effectively improves the machining precision and the machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of air compressor shell processing, and in particular relates to a high-precision processing device and a control method thereof. Background technique [0002] After the air compressor shell is cast, it needs to be milled, drilled and other cutting processes. The structure of the air compressor shell is shown in the attached figure 1 As shown, in the process of production, it is necessary to press and fix the air compressor casing through the fixing hole at the bottom, and then punch holes on one side of the air compressor casing. Usually, it will be processed before processing. Place the air compressor housing on the processing machine tool or pallet, and then move the air compressor housing by hand to enter the working range of the tool. However, the air compressor housing is heavy, and it is difficult to move it manually, and it is easy to move The loss of the pallet will affect the accuracy of the proce...

[0002] After the air compressor shell is cast, it needs to be milled, drilled and other cutting processes. The structure of the air compressor shell is shown in the attached figure 1 As shown, in the process of production, it is necessary to press and fix the air compressor casing through the fixing hole at the bottom, and then punch holes on one side wall of the air compressor casing. Usually, it will be processed before processing. Place the air compressor shell on the processing machine tool or on the pallet, and then move the air compressor shell by hand to enter the working range of the tool. However, the air compressor shell is heavy, and it is difficult to move it manually, and it is easy to move The loss of the pallet will affect the accuracy of the processing machine tool. In order to ensure the processing accuracy of the air compressor shell, it is also necessary to ensure the compression of the air compressor shell and improve the drilling efficiency.
