Problems solved by technology
[0003] The invention provides a positioning device for processing rectangular parts and a processing method for rectangular parts using the device. The positioning block is bonded to the surface of the part and the positioning platen, so that the parallelism between the positioning platen and the coordinate axis of the machine tool is transferred to the desired position. The processed rectangular parts simplify the alignment process and can solve the problem that the machining coordinate system of the part cannot be established by using the part's own shape positioning when processing the inner cavity and shape of the part at the same time

The invention discloses a movable positioning device and a rectangular part machining method utilizing the same, and provides the movable positioning device used for machining rectangular parts and an application method of the movable positioning device. The movable positioning device comprises three cylindrical positioning blocks identical in diameter, three ground positioning pressure plates, a plurality of pressure plates, adjusting bolts and supporting bolts, and the adjusting bolts and the supporting bolts are used in cooperation with the pressure plates; the movable positioning blocks are enabled to be attached to the parts and surfaces of the positioning pressure plates, so that depth of parallelism of the positioning pressure plates and a coordinate axis of a machine tool can be transmitted to the rectangular parts to be machined, the alignment process can be simplified, and problems that machining coordinate systems of the parts cannot be positioned and established by the aid of shapes of the parts when inner cavities and shapes of the parts are machined at the same time can be solved.
Description
technical field [0001] The invention relates to a live positioning device and a method for using the same, in particular to a live positioning device and a processing method for rectangular parts. Background technique [0002] For CNC machine tools, it is very important to determine the relative position of the workpiece in the machine tool coordinate system at the beginning of machining rectangular parts. Make it parallel to the X-axis and Y-axis of the machine tool coordinate system, and then use the edge finder to determine the X, Y, Z coordinate system values of the part in the machine tool coordinate system. When machining the shape of a rectangular part, the inner cavity of the part can be used for positioning, which simplifies the alignment process and reduces the alignment time. Similarly, when machining the inner cavity of a rectangular part, the inner cavity of the part can be used for positioning. correct way. However, when the inner cavity and shape of the pa...
