Description
[technical field]
This utility model relates to the technology neck of the technical field of machining, particularly Full-automatic drum base cylindrical precision turning
Territory.
[background technology]
In printer and photocopier, there is a class critical component, be called photosensitive drums.According to different operating principle, photosensitive
Drum is divided into toner cartridge, OPC drum etc., all has aluminium alloy drum base to be made according to different modes.Aluminium alloy drum base is that a kind of thin-walled is thin
Long aluminium-alloy pipe, its wall thickness is 0.75-1mm.
Paper " current situation and development of China's photosensitive drums aluminium drum base " (author: Guangzhou Research Institute of Nonferrous Metals, Zhang Zhongcheng and Huang
Quiet) middle proposition, the quality of aluminium drum base quality, final photocopying effect, production cost and the yield rate of appreciable impact photosensitive drums.Drum base
Key index in dimensional accuracy has: roundness of external circle, cylindrical linearity, cylindrical cylindricity.If a certain index not up to sets mark
Standard, drum base there will be the phenomenon of " car is non-round " in the course of processing, makes drum base outer round surface cause because local does not forms minute surface
Entirety is scrapped, thus particularly important to the control of precision in the cylindrical turning processing of drum base.
Chinese patent (application number: 201220264268.2) proposes a kind of numerical control for aluminum base-photoconductor drum turnery processing
Lathe structure, including lathe bed, lathe bed both ends are separately installed with main spindle box and tailstock, and tailstock is axially installed with locating centre,
Being provided with planker on lathe bed, planker is provided with knife rest, also includes stationary center and centering disc, centering disc is tight by bolt
The spindle nose being fixed in main spindle box, stationary center and centering disc are by the coaxial close-fitting of Morse's taper, and locating centre passes through gas
Dynamic device is coaxially installed on tailstock, and main shaft, centering disc, stationary center and locating centre are co-axially mounted.This technical scheme energy
Enough solve that positioning precision when existing numerically controlled lathe uses scroll chuck positioning and clamping workpiece is poor, clamping speed to a certain extent
Slowly, problem that product quality is low, but for drum this wall thickness of base be 0.75-1mm, draw ratio be the special workpiece of 10-13,
When carrying out rousing base cylindrical turning under above-mentioned installation way, still there will be the phenomenon that circle is beated, it is difficult to ensure Excircle machining quality.
The research worker of Beijing Machine Tool Inst. proposes one in paper " development of drum base cylindrical lathe " and controls drum base
In cylindrical turnery processing, weaken the technical scheme beated, in the internal control of drum base, specifically insert a damping rod, and adopt
With claw, the endoporus both ends of the surface of drum base being carried out blessing fixing, drum base is reduced vibration when with main shaft high-speed rotation and has one by this
Fixed effect.But the overall structure characteristic due to damping rod so that it needs manual operation with the handling of drum base, if application
On automatic production line, need the device that damping rod is loaded and unloaded by extra mounting design specially, this type of handler structure
Complex, it is also required to substantial amounts of monoblock type damping rod simultaneously and carries out turnover use, considerably increase the system of automatic production line
Causing this, too increase the process operation time, working (machining) efficiency is low.
So, it is now desired to one can high efficiency, high accuracy and carry out at low cost rousing base cylindrical automatic precision turning
Fixture.
