【正文】 has four to insert concretly and orienting the circle , clamping the cylinder etc. to make up mainly. Set is inserted four clamp the cylinder, Partition is fixed in inserting four concrete directions, Receive strength balancedly while clamping the work piece , Prevent the part from being out of shape. The key part of the jig , must make the dimensional tolerance of localization circle of four sets of jigs patible while orienting the circle And four gyration centre of jig turn round gyration of workingbench centre should coincident definitely too, could guarantee the machining accuracy of the part . Hydraulic pressure system The blood that the hydraulic pressure system of the lathe is equivalent to the human body likes the system, Clamping to process part, relax, to lift , rotate and drop workingbench, power head slippery platform enter, enter and is it is it realize to e by the hydraulic pressure system to retreat soon altogether soon. Centralized control stands by the hydraulic pressure mainly in the hydraulic pressure system, the hydraulic pressure electrical machinery is 22KW, the hydraulic pump is a variable blade pump, Slippery movement of platform to transfer by one three five electromagic valve speed valve control. Turn the lifting , dropping , turns round and restored to the throne of workingbench round, the clamping and relaxing of and the work piece , controlled by three two electromagic valves of Stone mainly. Electric system This lathe adopts the programmable controller of F160MR Mitsubishi as the central control pivot. It is hit, the large scale integrated circuit makes up , The function and logic of logic control with power store the function, the response speed is fast, the consumption is little , small, it is small to receive assignments, dependability is high, the monability is strong, not carried on online programming , debugged and revising to the procedure restraining from by the condition . It can realize that measure to the self diagnosis and trouble of the procedure , can carry on the logic operation and control of programming , timing and control that count, can easily person who realize, cable , liquid integrate. It is electric for exchange of system in, output not controlling for main shaft electrical machinery,hydraulic pressure electrical machinery, cool the electrical machinery. Direct current outputs ten routes of electromagic valves controlling the hydraulic pressure and standing mainly. The hardware of the electric system has a programmable controller mainly, voltage transformer , contactor , handle button , insurance device and rectification diode and flow diode , and journey switch ,etc. make up continuously。t turn machining center , main shaft of case round workingbench of to in, bee the vertical vertical overall arrangement. Loading and unload the work piece and processing the work piece can go on at the same time , does not interfere each other, Already cutting time and auxiliary time of the lathe has been coincident, thus improve the working efficiency of the lathe . the main ponent of the lathe up Lathe bed The lathe bed part must be enough bearing capacity and enough dynamic performance of rigidity and overload and store sparsly, so as to ensure that can keep its correct relative position for a long time between every part. Make up rigidity and precision keeping of part of lathe guarantee by the lathe bed part Lathe this lathe bed is it turn workingbench base round , set up of base , post and post cushion ,etc. form mainly to disappear. They play a making the basic skeleton of the lathe up role. Lathe bed part including counterweight weight is it make lathe total more than 70% of weight up to reach, therefore have good rigidity and antivibration performance , settle good foundation for guaranteeing the machining accuracy of the lathe . Slippery platform To is it is it enter give power part of sport to realize to used for slippery platform, It mainly by slippery platform, slippery pedestal and hydraulic pressure cylinder 3 part make up. The slippery pedestal is fixed on post, the cylinder block of hydraulic oil is fixed on slide , cylinder rod and slippery platform join each other, When working, hydraulic pressure cylinder regular, cylinder rod bring slippery platform make round sport at guide of slide. This slippery platform of hydraulic pressure of lathe belongs to the largescale slippery platform, enough energy stores . Slippery work of platform is it enter , stock and soon retreat 3 kinds of states altogether soon to have. Its movement was controlled together by the electric system and hydraulic pressure system. Install power heads and main shaft case on the slippery platform , is equipped with the pulley block of steel wire rope on the slippery tops , another end contains the counterweight one in the post, the purpose is to make the slippery platform move lightly on the slide , and can prevent the slippery ends from being overweight and glide . Power head and main shaft case The power head is the drives of sports of the main shaft , It drive each , main shaft of case output main shaft make cutter decide body sport. This lathe is got into, expanded , the diameter of hole cutter of dumpling is 25mm , 26 respectively. 6mm and 27mm, It is 35CrMoV to process the part material, hardness HRC2832, Consider the torsion stores coefficient , the lathe adopts the power very beginning of standard Model TD80A , the main electrical machin
