Description
Technical field
The present invention relates to a kind of retainer assembly equipment, relate in particular to a kind of gripping device that is used for the holder assembling.
Background technique
In the manufacturing of bearing, ribbon retainer or plastic cage need be loaded on the bearing automatically.The device of domestic now associated uses has two kinds: a kind of is pure craft, fully by artificial extracting and placement retainer; Another kind of mechanism utilizes gas to draw retainer, the absorption heads processing request of this device is very high, processing poor slightly just influence grasps effect even can't grasp, and this device can't produce a downward pressure when placing retainer, so it can't be placed with the plastic cage of bayonet socket, can not be pressed into bayonet socket to plastic cage, must be pressed into by hand by the people after placing.
Summary of the invention
A kind of gripping device that can realize the bearing holder assembling of grasping automatically, laying is provided when the technological deficiency that exists when solving the assembling of above-mentioned bearing holder, purpose of the present invention.
For reaching above-mentioned purpose, the present invention has adopted following technological scheme:
A kind of gripping device that is used for the bearing holder assembling, this device comprises connecting head, guide sleeve, central shaft and push rod cup, described guide sleeve is arranged on the connecting head below, central axle sleeve is located in the guide sleeve, be provided with compression spring A between central shaft and the connecting head, described push rod cup is set between guide sleeve and the central shaft, and is provided with the step surface that stops push rod cup below guide sleeve; The described central shaft outside is axially arranged with 3～8 mounting grooves, be respectively equipped with in the described mounting groove and pick up pawl, pick up being movably connected on the mounting groove of pawl, its inner side surface is provided with fulcrum, pick up the pawl bottom and be provided with claw hook, pick up pawl top and be provided with elastic component, described elastic component makes the default radially inner power in pawl top of picking up; Picking up below the fulcrum of pawl, described push rod cup inboard have at least any can with pick up pawl and be adjacent to mutually.
Above-mentioned elastic component makes picks up pawl around the trace rotation of fulcrum place, and can revert to original state again after rotating.In the time of work, whole device moves downward, when picking up pawl and touch retainer, the stressed elastic component that makes in lower end of picking up pawl is out of shape, pick up in the mounting groove of pawl retraction central shaft, in the claw hook insertion retainer internal diameter of picking up pawl, elastic component restores, claw hook snaps in the ball pocket of retainer, and retainer is held.Whole then device is parallel to be moved.During assembling, whole device moves downward, and central shaft is pressed onto the bearing inner race stop motion, compression press spring A.Because downward drive unit, push rod cup continues to descend, up to touching ribbon retainer, ribbon retainer is produced a downward power, also an end is stressed for the pawl of picking up that contact with ribbon retainer simultaneously, and elastic component is out of shape, and makes to pick up in the mounting groove that pawl is pressed into central shaft, retainer splits away off from pick up pawl like this, falls into bearing and finishes the action of laying ribbon retainer.
As preferably, described mounting groove is 4, and its corresponding pawl of picking up also is 4.Help balance like this and pick up retainer.
As preferably, described elastic component is an O type circle, and O type circle is arranged in the mount inlet of picking up pawl top.This material saving of O type circle has elasticity, can effectively make to pick up pawl and rotate around fulcrum.Certainly, above-mentioned elastic component also can replace with spring.
As preferably, the described inner side surface of picking up pawl is a circular arc, and the protuberance of circular arc is a fulcrum.
As preferably, be provided with stage clip B above the push rod cup, the top of stage clip B and connecting head lower end surface offset.Stage clip B can prevent that push rod cup from resisting retainer stubbornly and causing retainer to weigh wounded.
As preferably, the described pawl middle part of picking up is provided with notch, is provided with steel traveler in the notch, and the described pawl of picking up is movably connected in the mounting groove by steel traveler.Pick up pawl by steel traveler binding, make and pick up on the mounting groove that the pawl activity is fixed on central shaft.Certainly, above-mentioned activity means of fixation has multiple, also can pawl is hinged to be arranged in the mounting groove with picking up.
As preferably, described guide sleeve is provided with guider screw, and is provided with guiding groove in the central shaft outside, and the guiding slot port that the front end of described guider screw passes on the push rod cup cooperates with the guiding groove activity.The effect of guider screw and guiding groove is to make central shaft and push rod cup motion stabilization.
The present invention has realized that multiple retainer can both grasp and place owing to adopted above technological scheme, and central shaft can produce a down pressure during placement, can make retainer be pressed into bayonet socket.The present invention makes the assembling of retainer realize automation fully, grasps the efficient height.
