Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6. This utility model provides an oil injection device for bearing processing, including a worktable 1 and an oil tank 2 mounted on the surface of the worktable 1 via a bracket. An electric oil injector 3 is mounted on the surface of the bracket. A turntable 4 is arranged above the worktable 1. Several first sliding grooves 6 are evenly opened on the surface of the turntable 4. A clamping block 5 is slidably connected inside each first sliding groove 6. A V-shaped groove is opened on the adjacent side of every two clamping blocks 5. A first spring 7 is arranged inside each first sliding groove 6. The two ends of the first spring 7 are fixedly connected to the clamping block 5 and the turntable 4, respectively. Several positioning rods 8 are evenly rotatably connected inside the turntable 4. Each positioning rod 8 is located between two clamping blocks 5. Several abutment plates 9 are evenly arranged around each positioning rod 8. The abutment plates 9 are fixedly connected to the positioning rod 8 by second springs 10. When positioning bearings of different diameters is required, align the center inner hole of the bearing with the positioning rod 8 and press down. The inner wall of the bearing will first contact the abutment plate 9 and squeeze it. The second spring 10 will be compressed by force. The elastic potential energy of the second spring 10 makes the abutment plate 9 fit tightly against the inner wall of the bearing, thus achieving initial positioning of the bearing. When the bearing is pressed down, the outer wall of the bearing will squeeze the two clamping blocks 5, causing the clamping blocks 5 to slide inside the first slide groove 6 under pressure. The first spring 7 will be compressed by force. The elastic potential energy of the first spring 7 will allow the clamping blocks 5 to fit tightly against the outer wall of the bearing, thus clamping the bearing. The V-groove of the clamping block 5 can accommodate bearings of a certain diameter.

[0024] In this embodiment, the surface of the turntable 4 is evenly provided with a plurality of positioning grooves 17, each positioning groove 17 corresponding to a positioning rod 8. When the oiled bearing is removed with a clamp, one side of the clamp is inserted into the interior of the positioning groove 17 until it reaches the bottom of the bearing, and the other side of the clamp is placed on the top of the bearing, which facilitates clamping.

[0025] In this embodiment, a motor 11 is mounted on the bottom surface of the workbench 1, and a grooved wheel 13 is provided on the top surface of the workbench 1. The output shaft of the motor 11 passes through the surface of the workbench 1 and is connected to the grooved wheel 13. A Maltese cross 12 is rotatably connected to the workbench 1 via a bearing. The grooved wheel 13 and the Maltese cross 12 are meshed together, and the Maltese cross 12 is fixedly connected to the turntable 4. To facilitate lubrication of the bearings, after the bearings are positioned, the motor 11 is connected to an external power source and started. The grooved wheel 13 drives the turntable 4 to rotate via the Maltese cross 12. Due to the special tooth shape of the grooved wheel 13 and the Maltese cross 12, the Maltese cross 12 can only rotate 90 degrees after the grooved wheel 13 rotates one revolution. This indirectly allows the turntable 4 to rotate 90 degrees each time with an interval, which facilitates lubrication of the bearings.

[0026] In this embodiment, a first gear 14 is fixedly connected to the top of the Geneva wheel 13, and an internal gear 15 is rotatably connected to the bottom surface of the turntable 4 via a bearing. The internal gear 15 and the first gear 14 are meshed together. The end of the positioning rod 8 away from the abutment plate 9 passes through the surface of the turntable 4 and is in contact with the outer surface of the internal gear 15. When the Geneva wheel 13 rotates, it drives the internal gear 15 to rotate on the bottom surface of the turntable 4 through the first gear 14. When the Maltese cross 12 rotates, the internal gear 15 rotates synchronously with the Maltese cross 12, making them relatively stationary. When the Maltese cross 12 stops but the Geneva wheel 13 continues to rotate, the internal gear 15 will rotate along with it. When the internal gear 15 rotates, it will drive the positioning rod 8 to rotate due to friction. This causes the inner ring of the bearing to rotate but the outer ring to not rotate when the bearing is being lubricated, thereby causing the internal balls of the bearing to rotate and making the oil spread more evenly.

[0027] In this embodiment, oil guide grooves 16 are provided on the top surface of the turntable 4 at the positions of the positioning rods 8. The oil guide grooves 16 have a trapezoidal structure with the inclined surface facing downwards. An oil guide ring 18 is fixedly connected to the surface of the worktable 1. The opening of the oil guide ring 18 is located below the edge of the turntable 4, and an oil outlet frame 19 is fixedly connected to the surface of the oil guide ring 18. When oil overflows from inside the bearing, the oil will fall into the interior of the oil guide groove 16. Because the bottom surface of the oil guide groove 16 is inclined, the oil will slide along the oil guide groove 16 into the interior of the oil guide ring 18, and finally flow into the external collection box through the oil outlet frame 19 for collection and recycling.

[0028] The use of this utility model involves the following steps:

[0029] S1: When it is necessary to position bearings of different diameters, align the center inner hole of the bearing with the positioning rod 8 and press down. The inner wall of the bearing will first contact the abutment plate 9 and squeeze it. The second spring 10 will be compressed by force. The elastic potential energy of the second spring 10 makes the abutment plate 9 stick tightly to the inner wall of the bearing, thus achieving the initial positioning of the bearing. When the bearing is pressed down, the outer wall of the bearing will squeeze the two clamping blocks 5, causing the clamping blocks 5 to slide inside the first slide groove 6 under pressure. The first spring 7 will be compressed by force. The elastic potential energy of the first spring 7 will make the clamping blocks 5 stick tightly to the outer wall of the bearing, thus clamping the bearing. The V-groove of the clamping block 5 can adapt to bearings of a certain diameter. When it is necessary to inject oil, connect the electric oiler to the external power supply, draw oil from the oil tank 2 through the pipeline, and inject it into the bearing.

[0030] S2: To facilitate lubrication of the bearing, after positioning the bearing, connect the motor 11 to the external power supply and start it. The grooved wheel 13 will drive the turntable 4 to rotate through the Maltese cross 12. Due to the special shape of the teeth of the grooved wheel 13 and the Maltese cross 12, the Maltese cross 12 can only rotate 90 degrees after the grooved wheel 13 rotates one revolution. This indirectly makes the turntable 4 rotate 90 degrees each time with an interval, which is convenient for lubricating the bearing.

[0031] S3: When the grooved wheel 13 rotates, it will drive the inner gear 15 to rotate on the bottom surface of the turntable 4 through the first gear 14. When the Maltese cross 12 rotates, the inner gear 15 and the Maltese cross 12 rotate synchronously, so that the two are relatively stationary. When the Maltese cross 12 stops and the grooved wheel 13 continues to rotate, the inner gear 15 will rotate. When the inner gear 15 rotates, it will drive the positioning rod 8 to rotate due to friction. This makes the inner ring of the bearing rotate while the outer ring does not rotate when the bearing is lubricated, so that the balls inside the bearing rotate, making the oil spread more evenly.

[0032] S4: When oil overflows from inside the bearing, the oil will fall into the oil guide groove 16. Because the bottom surface of the oil guide groove 16 is inclined, the oil will slide into the oil guide ring 18 along the oil guide groove 16, and finally flow into the external collection box through the oil outlet frame 19 for collection and recycling.

[0033] S5: When removing the oiled bearing with the clamp, insert one side of the clamp into the positioning groove 17 until it reaches the bottom of the bearing, and place the other side of the clamp on the top of the bearing for easy clamping.

[0034] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
