The utility model is composed of a power transmission mechanism, a needle conveying mechanism, and an assemble mechanism, which makes the structure designed skillfully. Different needle charging mechanisms and cover dies can be changed, and the needle roller with various types can be assembled. The utility model has the advantages of small volume, multiple functions, low cost, and high work efficiency. Besides, the utility model is an ideal special device for the bearing to charge the needle.

Description

The bearing pointer assembling machine

The utility model relates to a kind of special device of needle roller assembling in the automobile gimbal bearing assembling field.

At present, the dress pin production method of automobile industry universal joint needle bearing all is that the armrest frock is joined, especially multiple garden diameter is less than the small size bearing of 15mm in, assemble needle roller by hand, because of operator's finger diameter greater than multiple garden in it, assembling difficulty is big, and work efficiency is also very low, is that enterprise wants to be situated between certainly and a difficult problem that can't resolve always.

The purpose of this utility model is the problem at above-mentioned existence, we have designed the pointer assembling machine that is used for the universal joint needle roller bearing without inner ring, for diameter at 25mm with interior, tack, the knob needle roller of length below 15mm, sleeve diameter is even more ideal less than the dress pin of the small size bearing of 20mm, work efficiency height but also alleviated working strength of workers not only makes the universal joint shaft of automobile industry take up pin production and realizes mechanization.

The utility model is formed power transmission mechanism by motor and connecting rod etc.: form defeated pin mechanism by hopper, rotating shaft etc.: formed combined mechanism and formed positioning device etc. by setting sleeve, positioning shaft and locating slot and form by rotating disk and cover die etc.For the needle roller of assembling different model, can finish the dress pin operation of various models by the cover that more reloads, rotating shaft and cover die.

Now be explained in detail in conjunction with the accompanying drawings

Fig. 1 is a schematic representation of the present utility model

Fig. 2 is the cut-away view of positioning device

Balance 7 and nut 6 are fastened on the upper end of rotating shaft 5, link into an integrated entity with hopper cover 2 by bearing (ball) cover 4, bolt 3 and bearing 9, hopper cover 2 is assemblied in the top of hopper 1, one end of connecting rod 8 is fixed on the balance 7, the other end is connected with the idler 10 that is assemblied in vertical rod 12 upper ends, the reciprocally swinging that driven by motor idler 10, process connecting rod 8 and balance 7 are done by a small margin rotating shaft 5, hopper 1 is fastened on the supporting rod 15 by tapering pin and bolt 11, and vertical rod 12 and supporting rod 15 all are fixed on the base 28.The structure of cover die 30 has overcoat 24, the internal layer of overcoat 24 is middle cover 14, the lower end is by spring 22 supportings, the inner chamber that can slide up and down middle cover 14 has mandrel 21, the bottom is connected with cushion block 23, fixing two cover dies 30 in the groove in the rotating disk 27, rotating disk 27 is assemblied on the base 28 by bearing 26 and stationary axle 25, handle 29 links to each other with rotating disk 27, by handle 29 rotating disk 27 is rotated, locate by the locating slot 20 on positioning shaft 19 and the rotating disk 27, make cover die 30 accurately, needle roller is fallen among the cover die 30 automatically facing to the hopper end opening.Positioning shaft 19 is contained in the setting sleeve 18, setting sleeve 18 is fastened on the base 18 by pressing plate and nut 17, one end of positioning shaft 19 is being adorned location axle pin 16, when the other end is subjected to the external force effect, just move right along chute 32 together with location axle pin 16, do not have external force to do the time spent, be subjected to the elastic force effect of spring 31 that positioning shaft 19 and locating stud 16 together are moved to the left, up to inserting locating slot 20.

The utility model embodiment: cleaned needle roller is packed in the hopper 1, makes reciprocally swinging by a small margin by the rotating shaft 5 of driven by motor, makes to have sequentially vertically to arrange in the gap in needle roller garden outside the inwall of hopper 1 and rotating shaft 5 to move down.Rotate rotating disks 27 by handle 29 and make cover die 30 aim at the hopper end openings, the needle roller cover die 30 of packing into.Joystick 29 again, rotate rotating disk 27, make another cover die 30 aim at hopper 1 feed opening, at this moment, the cover die 30 of having loaded onto needle roller is loaded onto need on the axle sleeve of needle roller facing to cover die 30, down presses with pointing, middle cover 14 stressed pressuring springs move down, and needle roller heads into axle sleeve by mandrel 21.

The utlity model has the advantage that volume is little, easy to operate, cost is low, work efficiency is high, can alleviate workman's labour intensity, is a kind of splendid special equipment of bearing dress pin.
