Description
Technical Field
The invention relates to the technical field of machining, in particular to a working method of a clamp for automatically and precisely turning an excircle of a printer drum base.
Background
Within printers and copiers, there is a class of critical components, called photoreceptor drums. According to different working principles, the photosensitive drum is divided into a selenium drum, an OPC drum and the like, and is made of an aluminum alloy drum base according to different modes. The aluminum alloy drum base is a thin-wall slender aluminum alloy pipe, and the wall thickness of the aluminum alloy drum base is 0.75-1 mm.
The final copying effect, the production cost and the yield of the photosensitive drum are obviously influenced by the quality of the aluminum drum base provided in the current situation and the development of the aluminum drum base of the photosensitive drum in China (authors: Guangzhou nonferrous metal research institute, Zhang loyal and Huangjing). The key indicators in the dimensional accuracy of the drum base are: excircle roundness, excircle straightness and excircle cylindricity. If a certain index does not meet the set standard, the drum base can generate the phenomenon of 'out of round turning' in the machining process, so that the whole drum base is scrapped due to the fact that a mirror surface is not formed on the outer circle surface of the drum base locally, and the control on the precision in the outer circle turning machining of the drum base is very important.
The Chinese patent (application number: 201220264268.2) provides a numerical control lathe structure for turning aluminum-based photoconductor drums, which comprises a lathe body, wherein a spindle box and a tailstock are respectively arranged at two ends of the lathe body, a positioning center is axially arranged on the tailstock, a dragging plate is arranged on the lathe body, a tool rest is arranged on the dragging plate, the numerical control lathe structure also comprises a fixed center and a centering disk, the centering disk is fastened at the end part of a spindle in the spindle box through bolts, the fixed center and the centering disk are coaxially and tightly matched through Morse taper, the positioning center is coaxially arranged on the tailstock through a pneumatic device, and the spindle, the centering disk, the fixed center and the positioning center are coaxially arranged. According to the technical scheme, the problems of poor positioning precision, low clamping speed and low product quality when the conventional numerical control lathe adopts the three-jaw chuck to position and clamp the workpiece are solved to a certain extent, but for the drum base, which is a special workpiece with the wall thickness of 0.75-1mm and the length-diameter ratio of 10-13, when the drum base outer circle is turned in the clamping mode, the phenomenon of circular runout still occurs, and the outer circle machining quality is difficult to ensure.
Researchers of Beijing machine tool research institute put forward a technical scheme for controlling a drum base to weaken bounce in outer circle turning in a thesis 'development of a drum base outer circle lathe', and specifically, a damping rod is inserted into an inner control of the drum base, and clamping jaws are adopted to clamp and fix two end faces of an inner hole of the drum base, so that the drum base has a certain effect of reducing vibration when rotating at a high speed along with a main shaft. But because the overall structure characteristic of shock attenuation stick for its and the loading and unloading of drum base need manual operation, if use on full-automatic production line, need additionally to install the device that the design was loaded and unloaded to the shock attenuation stick, this type of loading and unloading device structure is comparatively complicated, also needs a large amount of integral shock attenuation sticks to have enough to meet the need the use simultaneously, greatly increased full-automatic production line's manufacturing cost, also increased processing operation time, machining efficiency is low.
