TECHNICAL FIELD

[0001] The utility model relates to bearing production technical field especially relates to a ball arrangement conveying device for bearing assembly. BACKGROUND

[0002] Ball bearing is a kind of rolling bearing, and its core components include ball, inner ring, outer ring and retainer. Ball is installed in the middle of inner steel ring and outer steel ring, can bear larger load, and due to its small rolling friction resistance, the temperature generated by friction is lower.

[0003] When assembling ball bearing, ball needs to be arranged in the pipe at one time to facilitate the positioning and installation of ball between outer ring and inner ring by assembling equipment. In this process, ball needs to be arranged independently in the guide pipe in turn. The existing ball arrangement conveying equipment mainly sets up a circular pipe in ball bin and lifts ball into the circular pipe by the circular pipe, and the single arrangement of ball is very limited, and ball is pressed mutually, and ball cannot enter in single arrangement, therefore, the ball arrangement conveying device needs to ensure that ball can be arranged and conveyed quickly in multiple, and the speed of ball arrangement conveying into the guide pipe is improved. SUMMARY

[0004] The utility model provides a ball arrangement conveying device for bearing assembly in the prior art.

[0005] The utility model is realized through the following technical schemes:

[0006] A ball arrangement conveying device for bearing assembly, including ball bin, support frame, first air cylinder, push ball device and ball guide pipe, the support frame is fixedly arranged in the bottom of ball bin, the first air cylinder is installed in the bottom of support frame, the push ball device is fixedly arranged in the telescopic end of first air cylinder, the ball guide pipe is fixedly arranged in one side of ball bin, the push ball device includes lifting seat, ball clamping groove, clamping strip, second air cylinder and push block, the top of lifting seat is provided with clamping groove, the ball clamping groove is clamped in the top of lifting seat, the clamping strip is clamped in the clamping groove in the top of lifting seat, the second air cylinder is installed in the bottom of clamping groove in the top of lifting seat, and the push block is fixedly connected with the telescopic end of second air cylinder.

[0007] In a preferred embodiment of the utility model, the lifting seat is clamped in the bottom of ball bin, the bottom of ball bin is provided with guide groove matched with the lifting seat, and the telescopic end of first air cylinder is fixed with the bottom of lifting seat.

[0008] The outer surface of lifting seat is attached to the guide groove in the bottom of ball bin, effectively avoiding that ball is clamped in the gap between lifting seat and ball bin during the lifting and lowering process of first air cylinder controlling lifting seat.

[0009] In a preferred embodiment of the present invention, the top of the bead slot is provided with a V-shaped vertical cross-section limiting slot, and the bottom ends of the limiting slot at the top of the bead slot are provided with upward inclined ramps.

[0010] The V-shaped groove facilitates the placement of the balls in a single row at the top of the groove, while the slopes at both ends of the groove prevent the balls from rolling off during the lifting process of the first cylinder.

[0011] In a preferred embodiment of this utility model, the locking strip is movably connected to the top slot of the lifting seat by a pin, and one end of the locking strip is inclined.

[0012] In a preferred embodiment of the present invention, the push block is engaged outside the card strip, a guide groove is provided on the outer side of the inclined end of the card strip, a guide strip is provided on the inner side of the top of the push block to cooperate with it, and the guide strip on the inner side of the top of the push block is engaged in the guide groove on the surface of the card strip.

[0013] The extension of the second cylinder can move the push block forward. Since the inner guide strip on the top of the push block is locked in the inclined guide groove on the outer side of the locking strip, the forward movement of the push block can make the ball groove tilt upward around the connecting pin axis, thereby tilting the balls into the ball guide tube. The balls roll down in sequence, which facilitates the arrangement and sorting of the balls.

[0014] In a preferred embodiment of the present invention, the ball bearing guide is inclined downwards, and a receiving cover is provided at one end of the ball bearing chamber. The receiving cover at one end of the ball bearing guide has a trumpet-shaped structure.

[0015] The beneficial effects of this utility model are:

[0016] This ball bearing arrangement and conveying device lifts the balls in the ball bearing chamber, causing them to be locked in a single row into the ball bearing slot at the top of the lifting seat. The inclined surfaces at both ends of the ball bearing slot prevent the balls from falling out. Then, the cylinder controls the lifting seat to rise and controls the ball bearing slot to rotate, causing the balls to roll from one end of the ball bearing slot into the ball bearing guide. The balls roll into the ball bearing guide in sequence, completing the sorting and conveying work. This equipment can arrange and convey multiple balls at a time, effectively improving the ball bearing sorting and conveying speed and maintaining the ball bearing sorting and conveying effect.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0023] like Figures 1-4 The ball bearing assembly ball arrangement and conveying device shown includes a ball chamber 1, a support frame 2, a first cylinder 3, a ball pushing device 4, and a ball guide tube 5. The support frame 2 is fixedly installed at the bottom of the ball chamber 1, the first cylinder 3 is installed at the bottom of the support frame 2, the ball pushing device 4 is fixedly installed at the telescopic end of the first cylinder 3, and the ball guide tube 5 is fixedly installed on one side of the ball chamber 1. The ball pushing device 4 includes a lifting seat 41, a ball retaining groove 42, a retaining strip 43, a second cylinder 44, and a push block 45. The top of the lifting seat 41 has a retaining groove, the ball retaining groove 42 is engaged at the top of the lifting seat 41, the retaining strip 43 is engaged in the retaining groove at the top of the lifting seat 41, the second cylinder 44 is installed at the bottom of the retaining groove at the top of the lifting seat 41, and the push block 45 is fixedly connected to the telescopic end of the second cylinder 44.

[0024] Specifically, the lifting seat 41 is locked at the bottom of the ball chamber 1. The bottom of the ball chamber 1 is provided with a guide groove that cooperates with the lifting seat 41. The telescopic end of the first cylinder 3 is fixed to the bottom of the lifting seat 41. The top of the ball groove 42 is provided with a V-shaped vertical cross-section limiting groove. The bottom ends of the limiting groove at the top of the ball groove 42 are provided with upward inclined ramps. The locking strip 43 is movably connected to the top locking groove of the lifting seat 41 by a pin. One end of the locking strip 43 is inclined. The push block 45 is locked outside the locking strip 43. A guide groove is provided on the outer side of the inclined end of the locking strip 43. A guide strip that cooperates with the push block 45 is provided on the inner side of the top. The guide strip on the inner side of the top of the push block 45 is locked in the guide groove on the surface of the locking strip 43. The ball guide tube 5 is inclined downward. One end of the ball guide tube 5 is provided with a receiving cover. The receiving cover at one end of the ball guide tube 5 has a trumpet-shaped structure.

[0025] In this embodiment, the bearing balls that need to be arranged are placed in the ball magazine 1. Then, the first cylinder 3 at the bottom of the support frame 2 rises, causing the lifting seat 41 to rise. The outer side of the lifting seat 41 fits against the inner wall of the guide groove at the bottom of the ball magazine 1, so that when the lifting seat 41 rises, the balls will not fall into the gap at the connection between the guide groove and the lifting seat 41. After the first cylinder 3 lifts the lifting seat 41, a single row of balls will be locked into the V-shaped groove at the top of the ball locking groove 42. Since the top V-shaped groove of the ball locking groove 42 has an upward inclined slope at both ends, one end of the slope has a larger slope angle and a larger slope surface, which prevents the balls from falling from the end. The other end of the slope has a smaller slope surface and a smaller area, which plays a certain limiting effect and also prevents the balls from falling off later.

[0026] Furthermore, the second cylinder 44 extends, driving the push block 45 forward. The guide strip on the inner side of the top of the push block 45 is engaged in the guide grooves on both sides of the bottom of the retaining strip 43, and the guide grooves and guide strips are inclined. This causes the push block 45 to lift one end of the retaining strip 43 upward, so that the retaining ball groove 42 can rotate upward around the pin connecting the retaining strip 43 and the lifting seat 41, so that the balls roll down from the end of the retaining ball groove 42 with a smaller slope. The balls that roll down in sequence will fall into the trumpet-shaped receiving cover at the end of the ball guide tube 5, and then roll into the collection pipe in sequence along the downwardly inclined ball guide tube 5, thus facilitating the installation of bearing balls.
