Description

Technical Field

[0001] The invention relates to the technical field of grinding and cleaning of bearing outer rings, and in particular to a device for grinding and cleaning of bearing outer rings. Background Art

[0002] A bearing is a mechanical element that limits relative motion to a desired range of motion and reduces friction between moving parts. Bearings are designed to provide free linear motion of moving parts or free rotation about a fixed axis, or to prevent motion by controlling the vector of the normal force acting on the moving part.

[0003] As a tight component, the smoothness of the outer ring of the bearing will directly affect the fit between the bearing and the installation equipment. Therefore, in order to increase the smoothness of the outer ring of the bearing, each batch of bearings needs to be carefully polished and cleaned after polishing. There are two ways of polishing, one is manual polishing and the other is machine polishing, but the former has poor polishing accuracy and the latter has low polishing efficiency. In addition, when cleaning, the staff will place batches of bearing outer rings in water. The bearings overlap each other, and some dust has strong adhesion. It is difficult to achieve a good cleaning effect by just washing with water. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a bearing outer ring grinding and cleaning device, which overcomes the deficiencies in the prior art and effectively solves the problems of poor grinding accuracy or low grinding efficiency and general cleaning effect.

[0026] In this embodiment, the rotating baffle 9 is driven to rotate by the stepper motor 8, and the outer rings of the bearings that continuously move toward one end of the grinding table 1 will pass through the rotating baffle 9 one by one. The angle plate 13 is pushed to move by the push cylinder 12, and the outer rings of the bearings will move between the two driving wheels 15. The bamboo nozzle 11 can directly flush the cleaning liquid downward, and the driving wheel 15 is driven to rotate by the servo motor 14. The outer rings of the bearings can be cleaned in all directions, ensuring the thoroughness of the cleaning. After cleaning, the water can be dried in time by relying on the blanking mesh plate 16 and the net bag 19, which is convenient for taking materials.

[0027] Reference Figure 1 A base 20 is welded to the bottom outer wall of the grinding table 1 , and the rotating cylinder 17 is fixedly connected to the top outer wall of the base 20 .

[0028] Reference Figure 1 A sewage pool 21 is arranged on the top outer wall of the base 20 , and the blanking mesh plate 16 is arranged on the top of the sewage pool 21 .

[0029] Reference Figure 3 The top outer wall of the grinding table 1 is fixedly connected with a symmetrically distributed slide 22, and the grinding unit 4 and the driving rotating unit 5 are both slidably connected to the outer wall of the slide 22.

[0030] Reference Figures 2 to 4 A connecting frame 23 is fixedly connected to the outer wall of the top of the grinding table 1 , and the photoelectric sensor 10 and the bamboo nozzle 11 are both fixedly connected to the inner wall of the connecting frame 23 .

[0031] Reference Figure 1 A symmetrically distributed gantry 24 is fixedly connected to the top outer wall of the grinding table 1 , and two pushing cylinders 12 are fixedly connected to the top outer wall of the gantry 24 .

[0032] Reference Figures 1 to 4A PLC controller 25 is fixedly installed on the outer wall of the supporting leg of the grinding table 1, and the PLC controller 25 is connected to the servo guide rail 3, the grinding unit 4, the driving rotating unit 5, the stepping motor 8, the photoelectric sensor 10, the pushing cylinder 12, the servo motor 14 and the rotating cylinder 17 through signal lines.

[0033] Working principle: according to the size of the outer ring of the bearing, the grinding unit 4 and the driving rotating unit 5 are driven to approach each other through the servo guide rail 3, and the distance between the grinding unit 4 and the driving rotating unit 5 is adjusted. Then, the outer ring of the bearing to be ground is uniformly placed on the bottom support rod 2. By continuously pushing the outer ring of the bearing forward, the outer ring of the bearing will be transferred between the grinding unit 4 and the driving rotating unit 5. Under the mutual cooperation of the two, the outer ring of the bearing is ground while rotating, and a push rod 7 is set on the top of the bottom support rod 2. The push rod 7 can prevent the outer ring of the bearing from being bounced off due to uneven force.

[0034] When each of the frontmost bearing outer rings moves to the rotating baffle 9, the rotating baffle 9 is driven to rotate by the stepper motor 8, and the bearing outer rings will intermittently pass through the rotating baffle 9 one by one, allowing only one bearing outer ring to pass at a time, and then the push cylinder 12 pushes the angle plate 13 to move, and the bearing outer ring will move between the two driving wheels 15, and the driving wheel 15 is driven to rotate by the servo motor 14. At this time, the bamboo nozzle 11 directly flushes the cleaning liquid downward, and the bearing outer ring can be cleaned while rotating. After cleaning, the two driving wheels 15 move away from each other, and the bearing outer ring falls onto the blanking mesh plate 16 and then rolls into the net bag 19. The rotating cylinder 17 drives the column 18 to rotate to control the swing of the two net bags 19, which is convenient for one net bag 19 to receive materials and the other net bag 19 to take materials.
