At present, existing ball bearing adopts crown solid cage, use engineering plastics are injection molded, its principal feature is, quality is light, rub little, shortcoming is that version is crown, and intensity is low, easily distortion under high-speed case, when high-speed cruising, ball bearing is under deadweight and centripetal force effect, and the misalignment retainer Dou Kong center of steel ball, if retainer pocket hole dimension is too small, can reduce the storing lubricating grease amount in few pocket hole, retainer pocket internal surface of hole and steel ball surface become friction pair, and thermal value is large, and bearing can produce noise and abnormal sound; If retainer pocket hole dimension is excessive, when bearing high-speed cruising, can produce equally abnormal sound, lubricate operation life bad and reduction bearing, therefore need to ensure the size in the Ji Dou hole, position at retainer Dou Kong center, pocket encloses spherical surface in hole, spherical diameter is little, uses contact utensil to measure, and is not easy to place measuring point, each retainer has the pocket hole of 10 left and right, detection efficiency is low, uses other high-end precision detecting instruments, also has complex operation, efficiency is lower, is especially not suitable for production scene batch detection.
Summary of the invention:
Goal of the invention of the present utility model is to overcome the shortcoming that prior art exists, seek design a kind of ball bearing retainer pick-up unit is provided, realize the detection to pocket hole by measuring the utmost point maximum and minimum shifting amount of steel ball in crown retainer pocket hole, and according to the limit tolerance that in the drawing of retainer, size specifies, determine steel ball qualified minimum and maximum value of collecting together momentum in retainer pocket hole.
To achieve these goals, agent structure of the present utility model comprises base plate, dial gauge, dial gauge fixed leg, fixing pressure head, standard ball, positioning seat, afterburning lever holder, afterburning lever, spring, retainer to be measured, boss, location short column, stripe shape groove and adjusting nut; Dial gauge fixed leg is fixedly mounted on base plate, dial gauge is arranged on dial gauge fixed leg, positioning seat is fixedly mounted on base plate, positioning seat top is shaped with location short column, on the short column of location, place the retainer to be measured that is shaped with pocket hole, above retainer to be measured, be placed with fixing pressure head, in the pocket hole of retainer to be measured, be placed with standard ball, when measurement, location short column each stop location, pocket hole to retainer to be measured; Middle, positioning seat upper end is shaped with boss, and boss contacts with the standard ball in retainer to be measured, makes the center of standard ball and the pocket hole center superposition of retainer to be measured, ensures the accuracy of measuring; Afterburning lever holder is fixedly mounted on base plate, on afterburning lever holder, install and be shaped with slidable afterburning lever, one end of spring is arranged on afterburning lever by adjusting nut, the other end contacts with afterburning lever holder, the decrement of adjusting nut regulating spring, the power that makes to be applied in standard ball is 1 newton; Compress Spring produces spring force, in the effect of spring force, the relatively afterburning lever holder of afterburning lever is slided; On the horizontal direction of afterburning lever holder and vertical direction, manufacture and have stripe shape groove respectively, stripe shape groove is adjusted the contact position point of afterburning lever and standard ball, ensure contact position point, the measuring point of dial gauge and the center three point on a straight line of standard ball of afterburning lever and standard ball, improve accuracy of measurement.
Concrete measuring process of the present utility model is:
(1), standard ball is joined respectively in the pocket hole of retainer to be measured;
(2), on retainer horizontal positioned positioning seat to be measured, adjust retainer pocket to be measured hole site, make the pocket hole of retainer to be measured in position to be measured;
(3), fixing pressure head is installed on the retainer to be measured of placing, fixing pressure head limits moving radially of retainer to be measured, and coordinate with the internal diameter of retainer to be measured, make retainer to be measured automatic centering, positioning seat is shaped with boss in position to be measured, and boss holds up standard ball, makes the pocket hole center superposition of standard ball center and retainer to be measured, now, positioning seat limits the degree of freedom of retainer to be measured around center rotating;
(4), the position of adjusting dial gauge, the precompression of dial gauge gauge head to standard ball, makes standard ball depart from maximum to retainer to be measured outside by afterburning lever transmission in retainer pocket to be measured hole, writes down dial gauge registration A1;
(5), handle afterburning lever, the opposite side of standard ball is applied to the power that is less than 1 newton, make afterburning lever balance, now standard ball departs from maximum to retainer center position to be measured in retainer pocket to be measured hole, writes down dial gauge registration A2;
(6), calculate the absolute value of poor (A2-A1) of twice dial gauge registration, the standard ball in retainer pocket to be measured hole, within the scope of retainer to be measured qualified play radially, is and judges that whether pocket hole qualified.
The utility model is compared with existing, and it is simple in structure, easy to operate, and detection efficiency is high, and accuracy of detection is accurate, and cost is low, is applicable to the batch detection of production scene.
