Description
Technical field:
The utility model relates to the electric power transfer field, is specifically related to the coning sleeve tapering deep hole processing method and the special equipment thereof of carbon fiber composite core wire special electric power fitting.
Background technology:
For energy-saving and emission-reduction, China's power industry is introduced new technology in recent years energetically, new material is used for electric power transfer, carbon fiber composite core wire wherein with the gold utensil that is connected of supporting lead special use be the advanced technology of introducing the U.S..Along with China to constantly digesting and assimilating of introducing technology, carbon fiber lead and gold utensil domesticize at present, State Grid Corporation of China is progressively promoting this new technology.Applying in the process of this new technology, to the wherein processing of the tapering deep hole of the stainless steel coning sleeve of electric armour clamp strain clamp, all be to adopt the machining mode drill and ream, this processing mode exist cutter life short, production cost is high, efficient is low, percent defective is high and machining accuracy is difficult to reach defectives such as designing requirement.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of carbon fiber composite core wire special electric power fitting taper sleeve taper hole special equipment, improves working (machining) efficiency, the machining accuracy of taper sleeve taper hole, reduces the production and processing cost.
The utility model is achieved through the following technical solutions:
The processing method of carbon fiber composite core wire special electric power fitting taper sleeve taper hole comprises the following steps:
(1) at first to the processing dimension and the procedure of numerically controlled lathe setting workpiece, then workpiece to be processed is sandwiched in the chuck of numerically controlled lathe;
(2) start numerically controlled lathe, start the frock of cutter simultaneously; The workpiece of gripper chuck and cutter are rightabout and rotate, and workpiece is walked around moving with per minute 80-120, and cutter is walked around moving with per minute 1400-2400, workpiece is carried out high-speed milling; At least should carry out a roughing earlier, and then carry out a fine finishining.
Described rough machined milling amount is 0.5-0.7mm, and accurately machined milling amount is 0.2-0.4mm.The velocity of rotation of workpiece and cutter during fine finishining, all higher than the velocity of rotation of workpiece in the roughing and cutter.
Carbon fiber composite core wire special electric power fitting taper sleeve taper hole special equipment comprises the chuck of numerically controlled lathe, middle supporting plate, also comprises cutter and the frock that drives the cutter rotation, and described frock is arranged on the middle supporting plate.
Described frock is made of rotating shaft and housing, and rotating shaft is movably connected on housing by bearing, and described housing and middle supporting plate connect firmly.
The utility model is poor at the stainless steel material cutting ability, the characteristics that coning sleeve deep hole machining difficulty is big, designed the frock of cutting tool and clamping cutter, and frock has been arranged on the middle supporting plate of numerically controlled lathe, workpiece to be processed is sandwiched in the chuck of numerically controlled lathe.In process, workpiece to be processed rotates at a slow speed, cutter rotates at a high speed, and both are the rightabout rotation.
The housing of frock is an ironcasting in the utility model, and ironcasting can damping during with the power set transmission, prevents that frock from producing vibrations.Housing is installed power transmission shaft and bearing (thrust bearing, radial bearing, plane bearing) thereof by bore hole, installed thrust bearing and radial bearing purpose are the stability of rotation that guarantees axle, the right-hand member of power transmission shaft is provided with spacer, by bolted can further eliminate power transmission shaft end play, prevent axial runout.
The utility model compared with prior art has the following advantages:
One, because the utility model has adopted above-mentioned process for machining, allow the cutter rotary cutting, with be Milling Principle, therefore the stainless steel grinding dust that forms in working angles becomes the sheet of particle, cool off and wash with the cooling fluid of numerically controlled lathe, well solve the chip removal problem, stainless steel cuttings scratch surface of the work can not take place, influenced the surface accuracy of workpiece.
Two, because cutter is the rotation milling, a plurality of cutting edges have not been finished working angles on the cutter head under knife bar also is able to do in time the situation of strain, thereby avoided traditional reamer fixing, that do not move, problem such as knife bar cutter relieving, vibration, cutting is imperfect, the surface of the work tool marks obvious, workpiece accuracy difference in the process of processing tapering deep hole; Also avoided traditional reamer work in-process, the reamer contact-making surface is big, moment of torsion causes problems such as reamer fatigue, wearing and tearing greatly, influences the form tolerance and the dimensional tolerance of workpiece.
Three, the knife bar of cutter is selected the high-carbon steel material of good rigidly for use in the utility model, it is conical that the shape of knife bar is, with the tapering consistent (cross section of both same positions, the diameter of knife bar is less than the diameter of trepanning) of the tapering trepanning of workpiece, help cutting and chip removal like this.Cutter head adopts the proprietary material that cuts stainless steel, and has designed a plurality of cutting edges on the cutter head.The acquisition expenses of this cutter only is 1/10th of a former technology use cutter, method of the present utility model in addition, make cutter in process, because little with the contact-making surface of workpiece, moment of torsion is little, can not cause problems such as cutter fatigue, wearing and tearing, therefore not only make processed workpiece satisfy specification requirements such as form tolerance, dimensional tolerance, guarantee the machining accuracy (yield rate can reach 99 percent) of workpiece, and prolonged service life of cutter greatly, reduced production cost.
Four, production efficiency of the present utility model has improved more than four times than prior art.
