Description

Technical Field

[0001] This invention relates to the field of ball bearing installation equipment technology, specifically to an automatic ball bearing tooling for feeding. Background Technology

[0002] Bearing ball installation equipment is a mechanical device used to automatically install balls between the inner and outer rings of a bearing. Its core technologies include automatic ball feeding, sorting, conveying, and pushing installation. The basic working principle of existing equipment usually uses a vibratory feeder or a cylinder as a ball storage container. The balls are sent to the guiding mechanism through a conveying pipe, and then, through the cooperation of reciprocating gears or intermittent distributing rollers, the balls are separated one by one and pushed in a directional manner, ultimately accurately filling the balls into the cage pockets or the rolling grooves between the inner and outer rings.

[0003] In actual use, the above installation method is prone to problems such as missing balls, omissions, and overflow. When a large number of balls enter the eccentrically set inner and outer rings of the bearing at once, the balls tend to clump together and collide with each other, eventually causing the balls to be knocked out of the outer ring. This results in inconsistent quality of mass-produced bearings. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows: An automatic ball bearing feeding fixture includes a ball feeding mechanism, a measuring mechanism, and a feeding mechanism. The ball feeding mechanism includes an injection channel, two upper horizontal plates and two lower horizontal plates respectively embedded on the front and rear sides of the injection channel, six rollers rotatably mounted between the two upper horizontal plates and the two lower horizontal plates, a rubber belt movably sleeved between three adjacent rollers, multiple circular grooves formed on the outer wall of the rubber belt, two motors fixedly connected to the machine body and the upper horizontal plate near the front side of the injection channel, a pressure frame located inside the rubber belt and fixedly connected between the two upper and two lower horizontal plates, the output shaft of each motor fixedly connected to a roller near the top of the injection channel, and a measuring mechanism. The structure includes a support plate fixedly connected to the top of the injection channel, two supports symmetrically fixed to the top of the support plate, two measuring boxes rotatably installed between the two supports, a torsion spring fixedly connected between the supports and the measuring boxes, a main material box suspended from the top of the measuring boxes and fixedly connected to the support plate, an elastic baffle fixedly connected to the outer wall of the measuring boxes, and a feeding mechanism. The feeding mechanism includes a transition hopper rotatably installed between the two supports, a motor fixedly connected between the supports near the front side of the support plate and the transition hopper, a hose fixedly connected between the transition hopper and the injection channel, and two pull ropes fixedly connected between the measuring boxes and the transition hopper. The support plate has a round opening suitable for the hose to pass through.

[0006] By adopting the above technical solution, after the balls enter the injection channel, the output shafts of the two motors are controlled to rotate in opposite directions. Then, the three rollers in the same group cooperate to drive the rubber belt to rotate. Under the squeezing action of the pressure frame, the gap between the two rubber belts is reduced, thereby squeezing and conveying the balls. When each ball falls between the inner and outer rings of the eccentrically set bearing, it will be affected by the friction force at the bottom of the rubber belt. This friction force will carry the installed balls to the outside of the injection channel, thereby avoiding collisions between the subsequently arriving balls and the installed balls. By driving the installed balls, it can be prevented that the balls fall out of the bearing due to collision, thus ensuring the yield rate of batch-molded bearings.

[0007] In a preferred embodiment, the invention may be further configured such that two upper horizontal plates are located on top of two lower horizontal plates, the length of the upper horizontal plates is less than the length of the lower horizontal plates, and both are made of metal.

[0008] In a preferred embodiment, the present invention can be further configured such that: six rollers are arranged in two groups of three, with the two groups of rollers located on both sides of the injection channel, and the three rollers in each group are arranged in a right-angled triangle.

[0009] In a preferred embodiment, the invention may be further configured such that the depth of the circular groove is less than the thickness of the rubber strip, and the circular groove extends movably into the interior of the injection channel.

[0010] In a preferred embodiment, the present invention can be further configured as follows: two motors are connected in series, and both motors are electrically connected to an external PLC.

[0011] In a preferred embodiment, the present invention can be further configured such that the pressure frame is composed of a rubber plate and four L-bars, the four L-bars are respectively fixed to the front and rear sides of the rubber plate, and the outer ends of the four L-bars are respectively fixed to two upper horizontal plates and two lower horizontal plates.

[0012] In a preferred embodiment, the present invention can be further configured such that: the support frame consists of a profile plate and two short columns, the two short columns are respectively located on both sides of the transition bucket, the short columns are fixed to the inner side of the profile plate, and the torsion spring is sleeved on the outer side of the short columns.

[0013] In a preferred embodiment, the present invention can be further configured such that the elastic baffle is arc-shaped and the outer wall surface of the elastic baffle is movably fitted with the output end of the main material box.

[0014] In a preferred embodiment, the present invention may be further configured such that: a replenishing component is provided on the rear side of the main material box, the replenishing component includes a material preparation frame fixed to the rear side of the main material box, a push plate slidably disposed inside the material preparation frame, and two hydraulic cylinders fixed between the material preparation frame and the push plate, the two hydraulic cylinders being connected in series and electrically connected to an external PLC.

[0015] In a preferred embodiment, the present invention can be further configured such that: two tripods are fixedly connected between the main material box and the material preparation frame, and the two tripods are vertically symmetrical about the vertical center plane of the material preparation frame.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. In this invention, after the balls enter the injection channel, the output shafts of two motors are controlled to rotate in opposite directions. Then, the three rollers in the same group cooperate to drive the rubber belt to rotate. Under the squeezing action of the pressure frame, the gap between the two rubber belts is reduced, thereby squeezing and conveying the balls. When each ball falls between the inner and outer rings of the eccentrically set bearing, it will be affected by the frictional force at the bottom of the rubber belt. This frictional force will carry the installed balls to the outside of the injection channel, thereby avoiding collisions between the subsequently arriving balls and the installed balls. By driving the installed balls, it is possible to prevent the balls from falling out of the bearing due to collisions, thereby ensuring the yield rate of batch-molded bearings.

[0017] 2. In this invention, each time the output shaft of the motor rotates left or right, the hopper connected to it will be pulled downward by the pull rope to the measuring box close to the direction of rotation. Then, the other measuring box will be aligned with the discharge end of the main material box. Then, the balls in the main material box will smoothly roll into the measuring box. The length of the measuring box is designed to be equal to the sum of the diameters of the multiple balls filled at one time, thus preparing for fixed-quantity loading, thereby avoiding excessive loading in the later stage, further reducing the error rate of assembly operation, and ensuring the bearing forming effect.

[0018] 3. In this invention, when the balls in the main material box are quickly used up, the movable end of the hydraulic cylinder extends, and then the push plate squeezes the balls in the preparation frame into the main material box, so that the ball assembly operation can continue and production efficiency can be guaranteed.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic feeding bearing ball tooling. Example

[0024] Combination Figures 1-7 As shown, the present invention provides an automatic ball bearing feeding fixture, including a ball feeding mechanism 100, a measuring mechanism 200, and a feeding mechanism 300. The ball feeding mechanism 100 includes an injection channel 110, two upper horizontal plates 120 and two lower horizontal plates 130 respectively embedded in the front and rear sides of the injection channel 110, six rollers 140 rotatably installed between the two upper horizontal plates 120 and the two lower horizontal plates 130, a rubber belt 150 movably sleeved between three adjacent rollers 140, a plurality of circular grooves 160 formed on the outer wall of the rubber belt 150, two motors 170 fixedly connected to the machine body and the upper horizontal plate 120 near the front side of the injection channel 110, and a pressure frame 180 disposed inside the rubber belt 150 and fixedly connected between the two upper horizontal plates 120 and the two lower horizontal plates 130. The output shaft of the motor 170 is fixedly connected to the roller 140 near the top of the injection channel 110. The material measuring mechanism 200 includes a support plate 210 fixedly connected to the top of the injection channel 110, two supports 220 symmetrically fixedly connected to the top of the support plate 210, two measuring boxes 230 rotatably installed between the two supports 220, a torsion spring 240 fixedly connected between the supports 220 and the measuring boxes 230, a main material box 250 suspended above the measuring boxes 230 and fixedly connected to the support plate 210, and an elastic baffle 260 fixedly connected to the outer wall of the measuring boxes 230. The feeding mechanism 300 includes a transition hopper 310 rotatably mounted between two support frames 220, a motor 320 fixed between the support frame 220 and the transition hopper 310 near the front side of the support plate 210, a hose 330 fixed between the transition hopper 310 and the injection channel 110, and two pull ropes 340 fixed between the measuring box 230 and the transition hopper 310. The support plate 210 has a round opening suitable for the hose 330 to pass through.

[0025] Furthermore, the two upper horizontal plates 120 are respectively located on top of the two lower horizontal plates 130. The length of the upper horizontal plate 120 is less than the length of the lower horizontal plate 130. Both are made of metal. Using metal to make the upper horizontal plate 120 and the lower horizontal plate 130 can firmly support the roller 140 and the pressure frame 180, thereby improving the stability of the loading structure to a certain extent.

[0026] Furthermore, the six rollers 140 are arranged in two groups of three, with the two groups of rollers 140 located on both sides of the injection channel 110. The three rollers 140 in each group are arranged in a right-angled triangle. The layout design of the rollers 140 can guide the shape of the rubber belt 150, so that when the two rubber belts 150 cooperate with each other, they can both transport the balls and push the loaded balls to the outside of the injection channel 110 by friction, effectively avoiding the balls from colliding with each other during continuous loading.

[0027] Furthermore, the groove depth of the circular groove 160 is less than the thickness of the rubber belt 150, and the circular groove 160 extends movably into the inside of the injection channel 110. This size design allows the rubber belt 150 to smoothly convey the balls into the inner and outer rings of the eccentric bearing.

[0028] Furthermore, the two motors 170 are connected in series, and both motor 170 and motor 320 are electrically connected to an external PLC. This connection method makes the device more intelligent and improves the user experience.

[0029] Furthermore, the pressure frame 180 is composed of a rubber plate 181 and four L-bars 182. The four L-bars 182 are respectively fixed to the front and rear sides of the rubber plate 181, and the outer ends of the four L-bars 182 are respectively fixed to two upper horizontal plates 120 and two lower horizontal plates 130. The structural design of the pressure frame 180 can press the rubber belt 150 into the injection channel 110, ensuring that the rubber belt 150 can smoothly squeeze the balls down when it moves.

[0030] Furthermore, the support frame 220 is composed of a profile plate 221 and two short columns 222. The two short columns 222 are located on both sides of the transition hopper 310. The short columns 222 are fixed to the inner side of the profile plate 221, and the torsion spring 240 is sleeved on the outer side of the short columns 222. The structural design of the support frame 220 serves to stably support the measuring box 230, and at the same time, it also reduces the deformation of the torsion spring 240, ensuring the service life of the torsion spring 240.

[0031] Furthermore, the elastic baffle 260 is configured as an arc shape, and the outer wall surface of the elastic baffle 260 is movably fitted with the output end of the main material box 250. The installation method of the elastic baffle 260 can control the discharge time of the main material box 250 and effectively prevent the abnormal falling of the ball bearings. Example

[0032] Combination Figure 1 and Figure 7 As shown, based on Embodiment 1, a replenishing component 400 is provided on the rear side of the main material box 250. The replenishing component 400 includes a material preparation frame 410 fixed to the rear side of the main material box 250, a push plate 420 slidably disposed inside the material preparation frame 410, and two hydraulic cylinders 430 fixed between the material preparation frame 410 and the push plate 420. The two hydraulic cylinders 430 are connected in series and electrically connected to an external PLC. When the balls in the main material box 250 are quickly used up, the movable end of the hydraulic cylinder 430 extends, and then the push plate 420 squeezes the balls in the material preparation frame 410 into the main material box 250, so that the ball assembly operation can continue and ensure production efficiency. Example

[0033] Combination Figure 1 and Figure 7 As shown, in the above embodiment, two tripods 500 are fixedly connected between the main material box 250 and the material preparation frame 410. The two tripods 500 are vertically symmetrical about the vertical center plane of the material preparation frame 410. The tripods 500 can improve the installation firmness of the main material box 250 and the material preparation frame 410.

[0034] Working principle and usage process of this invention: When this device is put into actual use, motor 2 320 first drives the transition bucket 310 to deflect to the right. Under the traction of the pull rope 340, the measuring box 230 near the right side of the bearing plate 210 is pulled downward and tilted under the restraint of the torsion spring 240 connected to it. At this time, the elastic baffle 260 on the measuring box 230 just blocks the right discharge end of the main material box 250. At the same time, the pull rope 340 at the bottom of the other measuring box 230 is in a relaxed state. Therefore, under the restraint of the torsion springs 240 on its front and rear sides, it is kept on the same axis as the left discharge end of the main material box 250. Thus, the balls in the main material box 250 smoothly roll into the measuring box 230. The length of the measuring box 230 is designed to be equal to the sum of the diameters of the multiple balls filled at one time, thus preparing for fixed-quantity filling. Subsequently, the output shaft of motor 320 deflects to the left. Following the same principle, the main material box 250 containing a fixed number of balls tilts downwards, and the fixed number of balls quickly roll into the transition hopper 310, and then are guided by the hose 330 into the material injection channel 110. Next, the output shafts of the two motors 170 are controlled to rotate in opposite directions, causing the three rollers 140 in the same group to work together and drive the rubber belt 150 to rotate. Under the squeezing action of the pressure frame 180, the gap between the two rubber belts 150 is reduced, thereby squeezing and conveying a fixed number of balls. When each ball falls between the inner and outer rings of the eccentrically set bearing, it will be affected by the friction force at the bottom of the rubber belt 150. This friction force will carry the installed balls to the outside of the injection channel 110, thereby avoiding collisions between the subsequently arriving balls and the installed balls. By controlling the number of balls in advance and actively driving the installed balls, the loading operation can achieve zero errors and ensure the yield rate of batch-molded bearings.

[0035] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
