Description
Technical field
The utility model relates to a kind of dual milling cutter construction of full-automatic dynamic balance machine.
Background technology
Electric tool is important production and daily necessities.Rotor wherein exists amount of unbalance owing to be subjected to the influence of material, manufacturing process and assembling.Therefore when rotating, can produce vibration when rotor, bring noise, shorten harmful effect such as life of product, even bring danger, so must carry out dynamic balancing its rotor.
During electric tool was produced, the calibration equipment of its rotor dynamic balancing can be divided into two big classes, promptly manual dynamic balancing machine and the full-automatic dynamic balance machine proofreaied and correct.Manual correction dynamic balancing machine cost is lower, but production efficiency is low, and it is not high to need equilibrium process to rely on its balance quality of workman's experience simultaneously yet, and more to the cutting of rotor, and then the weakening of its electric property causes motor performance to degenerate, and can not satisfy the needs of High-efficient Production high-quality motor.In contrast to this, full-automatic dynamic balance machine then production efficiency is contour, and the balance quality height can be optimized the rotor cutting, but the machine price is more expensive relatively.Along with the development of China's electric tool industry, adopt full-automatic dynamic balance machine to become inexorable trend at present.
Therefore the full-automatic dynamic balance machine cutting must have deep understanding to the characteristic and the dynamic balancing process of present rotor to liking rotor.Be exactly total dynamically balanced principle is converted the amount of unbalance of rotor on two parallel planes, to these two correcting planes correction mass or go the heavy dynamic balancing that just realized in addition, in case and rigid rotator after the balance under a certain rotating speed then all be balance under any rotating speed.The analysis of rotor characteristics is mainly reflected on the material and manufacturing process to rotor, and present general rotor core generally all is that the tight punching press of silicon steel sheet is made, and is aided with coating, coiling again, drips operation such as lacquer.The amount of unbalance of rotor also just produces in these operations, therefore must carry out dynamic balance calibration to these rotors.
Particularly, thus dynamic balancing machine determines that by measuring station the size of amount of unbalance determines cutting output, goes heavily by the V-type milling in two ends of rotor, thereby makes rotor have the dynamic balancing of certain precision.And in concrete working angles, because turning to of milling cutter is constant, make that an end exists a problem of breaing up silicon steel sheet therein, as shown in Figure 1, especially obvious in the rotor that this phenomenon is not enough in the silicon steel sheet thrust or an enamelled coating is thin, cause new amount of unbalance, so must will adopt different cutting directions at two ends at this rotor.Through investigating the main at present dual mode that adopts of dynamic balancing machine both domestic and external: the one, the double-pole mode as the SK company of Japan, has two independently milling cutters on its dynamic balancing machine, move respectively by two milling cutters of programme-control and finish rotor and go heavy process; Another kind is the rotor rotation mode, and as PDX2 type dynamic balancing machine, its principle is to utilize cylinder to drive rotor platform Rotate 180 degree after having cut an end, and the other end is cut in feed again again.
The form of double-pole does not influence the location of rotor, exactly the measuring position is cut respectively.But because two milling cutters are independently, therefore must two cover milling cutter slide unit and control device, increased very high cost.And most critical is that the double-pole structure has proposed very high requirement to programme-control, in case program is made mistakes and cutter occurred hitting and can destroy whole milling cutter slide unit even whole dynamic balancing machine.The rotor rotation mode is owing to only need a milling cutter Mobile Slide to have very big advantage on cost, yet because rotor rotates through 180 degree, therefore very high to its positioner requirement, otherwise can lose cutting position, need detect dynamic equilibrium position again, have a strong impact on efficient.Therefore must make improvement to existing mode, thoroughly solve the problem that exists.
Summary of the invention
The technical problems to be solved in the utility model is to go heavily dynamic balancing at the rotor both-end, design a kind of simple in structure, with low cost, running is reliable, and can adapt to the dual milling cutter construction of the full-automatic dynamic balance machine of various rotors, make that cutting force points to the side that silicon steel sheet compresses in working angles, guarantee the precision of cutting.
The dual milling cutter construction of full-automatic dynamic balance machine of the present utility model, comprise that a side is the base of insulation board, the base two ends are the bearing a set of cups and the end cap that seals of mounting strap rolling bearing respectively, initiatively cutting axle and driven cutting axle are supported on the base by rolling bearing, initiatively cutting axle and driven cutting axle utilize a pair of external gear pump transmission campaign, both ends of main drive shaft is installed belt wheel and milling cutter respectively, driven shaft one end is installed milling cutter, driven shaft is installed an end and the driving shaft of milling cutter and one end of milling cutter is installed in the same side, driving shaft and driven shaft are installed a side of milling cutter and are stretched out insulation board, in belt wheel one side of base the carbon brush holder that is used for the cutting point location are installed.
Compared with prior art, advantage of the present utility model is:
1) simple in structure, reliable, be easy to realize;
2) two ends that utilize the milling cutter of a pair of reverse rotation to cut rotor respectively realize that dynamic balancing goes all to point to the direction that compresses silicon steel sheet in the heavy process, have guaranteed dynamic balance accuracy; Be applicable to most rotor cutting, especially iron core pressure mounting defective tightness or drip the relatively thinner rotor of stop-off lacquer glue-line.
3) only need a cover Mobile Slide equipment, saved cost;
4) motion control is simple, has avoided hitting the generation of cutter phenomenon.
