[0024] Refer to Figures 1-7, A lubrication device for a mechanical bearing, including a carrier 100, a clamping assembly 200 is installed on the surface of the carrier 100, an oil delivery assembly 300 is arranged on the top of the clamping assembly 200, a bearing body 400 is placed between the clamping assembly 200 and the oil delivery assembly 300. The clamping assembly 200 includes a motor 201, a brush plate 204 and a pressing plate 207. The motor 201 is arranged at the bottom of the carrier 100, the brush plate 204 is fixedly connected to the top of the carrier 100, and the pressing plate 207 is installed through the carrier 100. The oil delivery assembly 300 includes a positioning head 301, a fixing strip 309 and a fixing block 310. The positioning head 301 is located at the center of the top of the carrier 100, the fixing strip 309 is fixedly connected to the surface of the positioning head 301, the fixing block 310 is slidably connected in the fixing strip 309, and a nozzle 303 is fixedly installed at the bottom of the fixing block 310.

[0025] In the present invention, the number of the brush plates 204 is three, and they are circumferentially distributed on the carrier 100 with the bearing body 400 as the center. Among them, the brush plate 204 includes a single hard plate and multiple bundles of elastic brushes. The hard plate is fixedly connected to the carrier 100, and the elastic brushes are fixedly installed on the hard plate. The top of the elastic brushes extends between the inner ring and the outer ring of the bearing body 400, that is, the position where the balls are located. A supporting block is fixedly connected to the inner side of the pressing plate 207 for supporting the bottom of the outer ring of the bearing body 400 to meet the placement requirement of the bearing body 400.

[0026] During use, the number of the fixing strips 309 is three, and they are arranged in an array on the positioning head 301. With this design, the nozzles 303 at three positions can simultaneously spray oil and lubricate the balls on the bearing body 400.

[0027] Specifically, the output end of the motor 201 is fixedly connected with a connecting seat 216. The center of the top of the connecting seat 216 is fixedly connected with a movable shaft 209. A receiving sleeve 211 is fixedly sleeved on the top of the movable shaft 209. The inner wall of the receiving sleeve 211 is fixedly connected with a first spring 213, and the other end of the first spring 213 is fixedly connected with a pressing block 212.

[0028] In the present invention, the shape of the pressing block 212 is L-shaped, and the pressing block 212 is in sliding contact with the receiving sleeve 211. Through the setting of the first spring 213, elastic supporting force can be provided for the pressing block 212. In the installed state, it is ensured that the pressing block 212 is in close contact with the inner ring of the bearing body 400, so that the inner ring of the bearing body 400 rotates synchronously when the pressing block 212 rotates.

[0029] During use, an elastic anti-slip pad is fixedly inlaid on the outer side of the pressing block 212 to increase the contact friction with the inner ring of the bearing body 400, and the elastic anti-slip pad can be well attached to the arc surface of the inner ring of the bearing body 400 to further increase the contact friction between the two.

[0030] Specifically, a positioning seat 210 is fixedly connected to the top of the movable shaft 209. An external thread sleeve 214 is rotatably connected to the surface of the movable shaft 209. An internal thread sleeve 208 is threadedly sleeved on the surface of the external thread sleeve 214. The outer ring of the internal thread sleeve 208 is rotatably connected to a movable plate 203. The other end of the movable plate 203 is rotatably connected to the bottom of the pressing plate 207.

[0031] In the present invention, the top surface of the external thread sleeve 214 is smooth. A bearing seat is bolted to the center of the bottom of the bearing frame 100. The smooth surface on the external thread sleeve 214 is movably connected to the bearing seat through a damping bearing. With this design, the frictional force to be overcome during the rotation of the external thread sleeve 214 can be increased. When the insertion rod 217 is not in the inserted state, the motor 201 only drives the movable shaft 209 to rotate during operation. Through the settings of the internal thread sleeve 208 and the external thread sleeve 214, when the external thread sleeve 214 rotates actively, the internal thread sleeve 208 generates a vertical displacement. The number of the pressing plates 207 and the movable plates 203 is three each. When the internal thread sleeve 208 moves up and down, the three movable plates 203 can synchronously drive the three pressing plates 207 to slide and displace.

[0032] Specifically, a mounting frame 202 is fixedly connected to the bottom of the bearing frame 100. The motor 201 is bolted to the bottom of the mounting frame 202. A chute 206 is formed in the top of the bearing frame 100. A guiding rod 205 is fixedly connected to the inner wall of the chute 206. The guiding rod 205 penetrates through the pressing plate 207 and is in sliding contact with the pressing plate 207. Through the settings of the guiding rod 205 and the chute 206, the displacement of the pressing plate 207 can be guided, effectively ensuring the movement stability of the pressing plate 207. The guiding rod 205 and the chute 206 have a certain stroke. With this design, excessive displacement of the pressing plate 207 can be avoided, preventing the internal thread sleeve 208 from disengaging from the external thread sleeve 214. A displacement ring 218 is arranged on the outer ring of the external thread sleeve 214. A second spring 215 and an insertion rod 217 are respectively fixedly connected to the bottom of the displacement ring 218. The other end of the second spring 215 is fixedly connected to the outer ring of the external thread sleeve 214.

[0033] In the present invention, a jack is provided at the top of the connecting seat 216. The jack cooperates with the insertion rod 217. A damping ring is embedded inside the jack, which is used to increase the friction force that the insertion rod 217 needs to overcome during the insertion state, so as to prevent the insertion rod 217 from moving randomly. Similarly, in order to achieve the above operation, magnets can be installed at the bottom of the insertion rod 217 and inside the jack, and the magnets arranged up and down are in magnetic contact, which can also increase the force that the insertion rod 217 needs to overcome. The inner diameter of the displacement ring 218 is larger than the outer diameter of the external thread sleeve 214, that is, the displacement ring 218 does not contact the external thread sleeve 214. The number of insertion rods 217 is four, and they are all fixedly installed at the bottom of the displacement ring 218. The bottom of the external thread sleeve 214 is extended to provide an installation space for the insertion rod 217 and the second spring 215.

[0034] In the present invention, the oil delivery assembly 300 further includes a fixing rod 302. The bottom of the fixing rod 302 is fixedly connected to the top of the carrier 100. The top of the fixing rod 302 penetrates through the fixing strip 309 and is in sliding contact with the fixing strip 309. Through the setting of the fixing rod 302, the downward installation of the fixing strip 309 can be positioned and installed, and the fixing strip 309 can be prevented from rotating randomly. A displacement groove 307 is provided at the top of the fixing strip 309. A cross bar 306 is fixedly connected to the inner wall of the displacement groove 307. One end of the cross bar 306 is fixedly connected to the surface of the fixing block 310. Through the setting of the displacement groove 307, a sliding displacement space can be provided for the clamping block 304, the third spring 305, and the fixing block 310.

[0035] During use, through the setting of the cross bar 306, the sliding of the clamping block 304 and the fixing block 310 can be guided to ensure the stability of their movements.

[0036] Specifically, the cross bar 306 is sleeved with the clamping block 304 and the third spring 305 respectively. One end of the third spring 305 is fixedly connected to one side of the clamping block 304, and the other end of the third spring 305 is fixedly connected to one side of the fixing block 310.

[0037] In the present invention, the number of the clamping blocks 304 and the third springs 305 is two, and they are symmetrically distributed on the fixing block 310. The specifications and elastic coefficients of the two third springs 305 are the same. By setting the third spring 305, an elastic force can be provided for the clamping block 304, so that during the installation state, the inner and outer rings of the bearing body 400 can be clamped and positioned by the clamping block 304.

[0038] Specifically, an oil delivery pipe 308 is connected to the top of the nozzle 303. The other end of the oil delivery pipe 308 is connected to an external oil pump. Through the setting of the oil delivery pipe 308, under the action of the external oil pump, the lubricating oil can be transmitted through the oil delivery pipe 308 and finally sprayed out through the nozzle 303.

[0039] The working principle of the present invention: S1: First, according to the specifications of the bearing body 400 to be lubricated, press the displacement ring 218 so that the bottom end of the insertion rod 217 is placed into the connecting seat 216, and the second spring 215 is compressed. At this time, control the motor 201 to work, so that the movable shaft 209 and the external thread sleeve 214 rotate together. Under the screw drive, the internal thread sleeve 208 gradually moves downward. Under the connection of the movable plate 203, the pressing plate 207 will slide in the chute 206 to conform to the specifications of the bearing body 400, and actively move up the displacement ring 218 to disengage the insertion rod 217 from the connecting seat 216; S2: After the bearing body 400 is placed, control the motor 201 to work again. The three pressing plates 207 complete the stable clamping of the bearing body 400. At this time, the upper end of the brush plate 204 is placed into the bearing body 400; S3: During the downward movement of the bearing body 400, press the pressing block 212 inward, and the first spring 213 is compressed. After the bearing body 400 is placed, release the pressing block 212. Under the elastic support of the first spring 213, the pressing block 212 is in close contact with the inner ring of the bearing body 400; S4: Move the oil delivery assembly 300 downward. Under the cooperation of the positioning seat 210 and the positioning head 301 and the positioning function of the fixing rod 302, the oil delivery assembly 300 is quickly and accurately installed downward. The clamping block 304 will be extruded by the inner and outer rings of the bearing body 400 and displace outward, and the third spring 305 is stretched, so as to keep the fixing block 310 always at the center position between the two clamping blocks 304. Since the inner and outer rings of the bearing body 400 have the same specifications, the fixing block 310 and the nozzle 303 can be located at the ball of the bearing body 400; S5: Control the external oil pump to work, so that the lubricating oil is sprayed out from the oil delivery pipe 308 and the nozzle 303 to the ball of the bearing body 400. At the same time, control the motor 201 to work, so that the movable shaft 209 rotates alone, and cooperate with the first spring 213 and the pressing block 212 to drive the inner ring of the bearing body 400 to rotate, so that the ball of the bearing body 400 rotates. At the same time, the rotating ball receives the lubricating oil sprayed by the nozzle 303 and is elastically brushed by the brush plate 204, and the overall lubrication effect is better, and it can be well adapted to different specifications of the bearing body 400.

[0040] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0041] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
