Description

Technical Field

[0001] This utility model relates to the field of bearing outer ring grinding and cleaning technology, and in particular to a bearing outer ring grinding and cleaning device. Background Technology

[0002] A bearing is a mechanical component that restricts relative motion within a desired range of motion and reduces friction between moving parts. Bearing design can allow for free linear motion or free rotation of moving parts about a fixed axis, or prevent motion by controlling the vector of the normal force acting on the moving parts.

[0003] As a tightly fitted component, the smoothness of the bearing's outer ring directly affects the fit between the bearing and the installed equipment. Therefore, to increase the smoothness of the bearing's outer ring, each batch of bearings needs to be meticulously polished, and then cleaned. There are two polishing methods: manual polishing and machine polishing. However, the former has poor polishing precision, while the latter has low polishing efficiency. In addition, during cleaning, workers place batches of bearing outer rings in water. The bearings overlap with each other, and some dust has strong adhesion, making it difficult to achieve a good cleaning effect simply by washing with water. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a bearing outer ring grinding and cleaning device, which overcomes the shortcomings of the prior art and effectively solves the problems of poor grinding accuracy, low grinding efficiency and mediocre cleaning effect.

A grinding unit and a drive rotation unit are fixedly connected to the two servo guide rail sliders respectively. A fixing plate is welded to the top outer wall of the grinding table, and a top rod is welded to one side of the fixing plate.

A servo motor is fixedly connected to the outer wall of one side of the corner plate, and a drive wheel is fixedly connected to the output shaft of the servo motor. A material dropping screen is welded to the outer wall of one end of the grinding table, and a rotating cylinder is installed at the bottom of the material dropping screen. A column is fixedly connected to the piston rod of the rotating cylinder, and symmetrically distributed mesh bags are welded to the top outer wall of the column.

[0008] Preferably, a base is welded to the bottom outer wall of the grinding table, and the rotary cylinder is fixedly connected to the top outer wall of the base.

[0009] Preferably, the outer wall of the top of the base is provided with a sewage tank, and the material discharge mesh is provided on top of the sewage tank.

[0024] In this embodiment, based on the size of the bearing outer ring, the servo guide rail 3 can drive the grinding unit 4 and the drive rotation unit 5 to approach each other. The bearing outer ring to be ground can be uniformly placed on the bottom support rod 2.

A stepper motor 8 is fixedly connected to the top outer wall of the grinding table 1, and a rotating baffle 9 is fixedly connected to the output shaft of the stepper motor 8. A photoelectric sensor 10 is installed on the top of the bottom support rod 2, and a bamboo-joint spray pipe 11 is installed on one side of the photoelectric sensor 10. A push cylinder 12 is symmetrically distributed at one end of the top outer wall of the grinding table 1, and a corner plate 13 is fixedly connected to the piston rod of the push cylinder 12. A servo motor 14 is fixedly connected to one side outer wall of the corner plate 13, and a drive wheel 15 is fixedly connected to the output shaft of the servo motor 14. A material dropping screen 16 is welded to one end outer wall of the grinding table 1, and a rotating cylinder 17 is installed at the bottom of the material dropping screen 16. A column 18 is fixedly connected to the piston rod of the rotating cylinder 17, and a symmetrically distributed net bag 19 is welded to the top outer wall of the column 18.

[0026] In this embodiment, the stepper motor 8 drives the rotating baffle 9 to rotate, and the outer rings of the bearings that move continuously toward one end of the grinding table 1 pass through the rotating baffle 9 one by one. The push cylinder 12 pushes the corner plate 13 to move, and the outer rings of the bearings move between the two drive wheels 15. The bamboo joint spray pipe 11 can directly rinse the cleaning liquid downwards. The servo motor 14 drives the drive wheels 15 to rotate, and the outer rings of the bearings can be cleaned from all directions, ensuring thorough cleaning. After cleaning, the material can be dried in time by the material dropping screen 16 and the net bag 19, which is convenient for material removal.

[0027] Reference Figure 1 The grinding table 1 has a base 20 welded to its bottom outer wall, and the rotary cylinder 17 is fixedly connected to the top outer wall of the base 20.

[0028] Reference Figure 1 The base 20 has a sewage tank 21 on its top outer wall, and the material drop plate 16 is set on top of the sewage tank 21.

[0029] Reference Figure 3 The top outer wall of the grinding table 1 is fixedly connected with symmetrically distributed slides 22, and the grinding unit 4 and the drive rotation unit 5 are both slidably connected to the outer wall of the slides 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 joint nozzle 11 are both fixedly connected to the inner wall of the connecting frame 23.

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

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

[0033] Working principle: Based on the size of the bearing outer ring, the servo guide rail 3 drives the grinding unit 4 and the drive rotation unit 5 to approach each other. After adjusting the distance between the grinding unit 4 and the drive rotation unit 5, the bearing outer ring to be ground is placed on the bottom support rod 2. By continuously pushing the bearing outer ring forward, the bearing outer ring will be transferred between the grinding unit 4 and the drive rotation unit 5. With the cooperation of the two, the bearing outer ring is ground while rotating. A top rod 7 is set at the top of the bottom support rod 2. The top rod 7 can prevent the bearing outer ring from being bounced off due to uneven force.

[0034] When each outer ring of the foremost bearing moves to the rotating baffle 9, the stepper motor 8 drives the rotating baffle 9 to rotate. The outer rings of the bearings will pass through the rotating baffle 9 one by one intermittently, allowing only one outer ring of the bearing to pass at a time. Then, the push cylinder 12 pushes the corner plate 13 to move, and the outer ring of the bearing will move between the two drive wheels 15. The servo motor 14 drives the drive wheels 15 to rotate. At this time, the bamboo joint spray pipe 11 directly washes the cleaning liquid downwards. The outer ring of the bearing can be cleaned while rotating. After cleaning, the two drive wheels 15 move away from each other, and the outer ring of the bearing falls onto the material dropping screen plate 16 and then rolls into the net bag 19. The rotating cylinder 17 drives the column 18 to rotate, which can control the swing of the two net bags 19, making it convenient for one net bag 19 to receive material and the other net bag 19 to pick up material.
