Description
Technical field the utility model relates to a kind of processing unit (plant) of bearing, especially for the device of processing steel ball.
Background technology existing bearing big steel ball (more than the Φ 40mm) all adopts vertical lapping machine to grind.This vertical lapping machine has decides, moves two horizontal abrasive sheets, respectively being provided with cross section, a few road on their relative annular abrasion faces is semicircular concentric groove, and the groove of two abrasive sheets is corresponding up and down, constituting the cross section is circular closed-loop, polished steel ball places in it, by hand abrasive pastes are directly spread upon on the polished steel ball, starting moving abrasive sheet can grind.The shortcoming of above-mentioned single ditch lapping device is: (1) can only revolve round the sun and rotation in the raceway groove of oneself owing to steel ball, and the centrifugal force of the interior raceway groove of centrifugal force that the outer raceway groove of abrasive sheet produces is big, so the consumption of outer raceway groove product size is fast, cause inside and outside raceway groove ball size tolerance inconsistent, easily produce the tail ball during combo.(2) for preventing that steel ball two balls contact when grinding from producing burn, so idle batching sphere is set between steel ball, it occupies 1/3 raceway groove approximately, make the original steel ball number that can process with regard to limited grinding space still less, the number steel ball is organized in the little very difficult processing of product lot quantity greatly, if selection may be gathered together enough one group in a large amount of steel balls, but cost is high.(3) by hand smear abrasive pastes and can't guarantee that evenly, then size consumption is fast in the abrasive material many places, cause with coil in addition big with raceway groove product size discreteness, accuracy class is low.
Summary of the invention the utility model mainly provides a kind of basic identical with batch product size, and accuracy class height, product lot quantity are big, the waste of anury ball, can produce the bearing big steel ball circular grinding device of big group of number steel ball.The utility model mainly includes: fixed, moving two abrasive sheets, the dish of losing, material road and grinding agent cycling mechanism.Wherein the structure of fixed, moving two abrasive sheets is same as the prior art substantially, and promptly respectively being provided with cross section, a few road on their relative annular abrasion faces is semicircular concentric groove, and the groove of two abrasive sheets is corresponding, and constituting the cross section is circular closed-loop.But two abrasive sheet abradant surfaces of the present utility model are vertical state.Be provided with the rectangular through-hole corresponding near crossing the horizontal section of axis deciding abrasive sheet, have in this through hole to be fixed on and decide the material road that two channel steel shapes up and down on the abrasive sheet tilt and pass with the abradant surface width.Wherein the higher end (entrance point) in material loading road is near the abradant surface of moving abrasive sheet, and a lower end (port of export) is hung to the dish of the losing side of scoring; The abradant surface of the approaching moving abrasive sheet of an end (port of export) that the blanking road is lower, a higher end (entrance point) is adjacent with the dish rotating disk of losing.Preferably the loading and unloading road is provided with and corresponding straight flute road, abrasive sheet abradant surface raceway groove cross section, and it is steel ball guiding of turnover abrasive sheet, guarantees turnover ball is smooth and easy to put in place, prevents that dislocation from stopping up.The above-mentioned dish of losing have one can be by the rotating disk of motor drives rotation, there is a vertical column at this rotating disk middle part, on the outer peripheral face of column, be fixed with the annular slab of level, be provided with the coaxial tubular coaming plate that internal diameter is a bit larger tham the annular slab external diameter in this annular slab outside, this coaming plate is fixed on the following bearing.The position that this coaming plate is corresponding with the blanking road is provided with slit opening in addition.In losing dish, this is provided with the dividing plate that steel ball that has just entered and the steel ball that is about to away can be separated, this dividing plate places the bar shaped of certain altitude dividing plate on the annular slab, a stile of one end and blanking road entrance point joins, though the other end is a free end, the steel ball that moves with rotating disk just is pushed into it column place.The utility model also is provided with the grinding agent cycling mechanism.Be provided with the grinding agent jet pipe above near the blanking road entrance point, it can make the liquid grinding agent evenly be sprayed at and be about to grinding aid on the polished steel ball.Below two abrasive sheets, be provided with the grinding agent groove that the opening of collecting grinding agent makes progress.The circulating pump feed tube places in the grinding agent groove, and drain pipe then links to each other with the grinding agent jet pipe by conduit, by circulating pump grinding agent is recycled.
The utility model course of work is as follows: polished a collection of steel ball is placed in the dish of losing, and its rotating disk orders about rotation down at motor, so the steel ball that just drives on it rotates.In the time of near steel ball forwards blanking road entrance point to, the grinding agent jet pipe sprays grinding agent on it.The steel ball that one row has a grinding agent rolls down to the raceway groove of moving abrasive disk naturally along the inclined-plane in blanking road, and is driven in two abrasive disks by moving abrasive disk and to revolve round the sun and rotation.When steel ball forwarded material loading road entrance point to, the steel ball that has ground a circle at two abrasive disks then rolled out naturally along the inclined-plane in material loading road, freely fell into goal one side that the dish of losing is separated by dividing plate from the material loading road port of export.Lose dish in when work the steel ball position change at random on it, lose when coiling out ball one side blanking road entrance point when steel ball forwards to again, repeat top process again, till grinding reaches standard-required.
The utility model has following advantage compared to existing technology:
1. owing to adopt the dish circulation turnover steel ball of losing, therefore steel ball switch mutually in the dish of losing, the probability that makes every steel ball enter each groove equates, stressed and grinder is understood uniformity, thereby realized that batch ball size discreteness is little, basic identical together, need not size separation, the waste of anury ball, geometric accuracy is improved synchronously.Adopt the dish of losing that product lot quantity is increased simultaneously, general every dish has 200-250 kilogram steel ball approximately, thereby is easy to produce big group of number steel ball, and combo rate height, production cost are low.
2. adopt grinding fluid to substitute grinding cream, not only guaranteed to have solved with the big problem of dish product size discreteness with dish steel ball stock removal uniformity, and the grinding precision height, meet or exceed GB308 standard G16 level level, the product that processes than existing equipment improves 2 ranks.Grinding fluid can be recycled in addition, has saved processing cost.
3. the steel ball that processes of the utility model can reach the regulation requirement once going on foot, and therefore can reduce by two procedures, the saving of labor, save time, province's expense, reduce the processing cost of grinding greatly.
4. in the utility model, low mutually the disappearing of centrifugal force that the gravity of steel ball and steel ball produce with the abrasive sheet revolution, so steel ball dispersion naturally in raceway groove do not need batching sphere, have increased effective grinding space, have improved production efficiency.
