Description

Technical Field

[0001] This invention relates to the field of miniature bearing transfer technology, and in particular to a transfer device for a miniature bearing cage. Background Technology

[0002] Miniature bearings are a category of rolling bearings with a nominal outer diameter of less than 26 mm. Among them, miniature ball bearings with a metric outer diameter of less than 9 mm are called ultra-miniature bearings. The main materials include carbon steel, bearing steel, stainless steel, plastic and ceramic. The smallest inner diameter can be as small as 0.6 mm. Common specifications cover metric 68, 69, 60 series and imperial R series miniature deep groove ball bearings. Derivative structures include types with ZZ steel plate dust covers, RS rubber seals, Teflon seals and flanges. These bearings are composed of inner and outer rings, bearing balls, cages and other components. They are mainly used in high-speed equipment such as miniature motors, instruments, hard disk motors, computer cooling fans and other equipment, and are gradually expanding into medical devices, industrial robots, autonomous driving and other fields.

[0003] Existing miniature bearing cage transfer devices typically involve loading the product into a suitable position and then clamping it for positioning and transfer. However, in the existing technology, the fixed clamping method can easily cause micro-deformation of the bearing cage during transportation, which adversely affects the bearing's load-bearing capacity during subsequent transportation and application. Therefore, we propose a miniature bearing cage transfer device to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a transfer device for miniature bearing cages. This device primarily utilizes a three-stage hollow tube installed below each set of the mounting block. The three-stage hollow tube sets up the fixing ring and slip ring. After installation, the flexible air tube, air pump, and suction nozzle are attracted to the top. A pneumatic pusher and adjusting rod push the magnetic ball out of the gaps in the three-stage hollow tube. This operating method effectively transfers and transports the cage under a multi-force balance through the action of magnetism and air pressure without direct hard contact. During this process, the product is less likely to deform, thereby reducing the user's loss costs.

[0045] The working principle of this invention is as follows: A sufficient number of miniature bearing cages are placed into the circular groove 105. The equipment is placed at the processing location by the shock absorber 101 and the base plate 102 to achieve a supporting effect. Then, the vibration base 104 outputs vibration force to initiate resonance, driving the spiral track 106 to vibrate. The cages gradually rise and are sorted along the spiral track to avoid stacking. The shock absorber 101 buffers the vibration to prevent the equipment from shifting. The sorted cages enter the track groove 107. The pneumatic arc block 109 extends and retracts to adjust the cage posture, directionally conveying it to the cylindrical track 1010.

The pneumatic arc clamp 2011 comes into contact with the retainer from all sides and pneumatically telescopically clamps the retainer.

The drive gear 204 drives the driven gear 203 to rotate, which drives the square frame 205 to rotate through the assembly base 202, so that the pneumatic arc clamp 2011 is aligned with the discharge end of the cylindrical track 1010.

Pressure is applied to prevent damage to the cage. The horizontal lead screw 406 and the vertical lead screw 4010 work together to move the cage laterally and longitudinally. The electric rotating seat 408 and the electric rotating rod 4012 adjust the cage angle to achieve multi-dimensional precise transfer. The magnetic ball 4027 assists in positioning and improves transfer accuracy. The cage is transferred above the discharge conveyor belt 307.
