Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and in particular to a grinding equipment for processing a lubricated bearing seat. Background Art

[0002] The bearing seat is a base that provides stable support for the bearing. The bearing seat fixes the bearing in the exact position to ensure that oscillation and displacement are minimized when the machine rotates at high speed, thereby ensuring mechanical precision and stability. In order to prevent relative rotation between the bearing seat and the bearing, a keyway is provided on the inner wall of the bearing seat and a pin is provided on the outer wall of the bearing. The engagement of the pin and the keyway limits the relative rotation between the bearing and the bearing seat in the circumferential direction. This engagement method ensures that the positions of the bearing and the bearing seat in the circumferential direction are relatively fixed, so that they can work together to support and transmit the movement and power of the shaft.

[0003] The existing bearing seat grinding equipment uses a grinding roller to grind the inner wall of the bearing seat. When the grinding roller grinds the inner wall of the bearing seat, the grinding roller cannot fully contact the inside of the keyway, resulting in the inside of the keyway being relatively rough after grinding. During the use of the bearing seat, the keyway and the pin on the bearing are constantly worn, resulting in poor engagement between the keyway and the pin, and the bearing is prone to vibration during use; therefore, it does not meet the existing needs. In this regard, we have proposed a grinding equipment for lubricating bearing seat processing. Summary of the Invention

[0004] The present invention provides a grinding device for processing a lubricated bearing seat, which can automatically grind the keyway of the bearing seat. After grinding, the interior of the bearing seat is smooth and the pin is not easily worn, thereby ensuring the normal engagement of the keyway and the pin, and the bearing is not prone to vibration during use. This solves the problem mentioned in the above background technology that the existing bearing seat grinding equipment uses a grinding roller to grind the inner wall of the bearing seat. When the grinding roller grinds the inner wall of the bearing seat, the grinding roller cannot fully contact the inside of the keyway, resulting in the inside of the keyway being relatively rough after grinding. During the use of the bearing seat, the keyway and the pin on the bearing are constantly worn, resulting in poor engagement of the keyway and the pin, and the bearing is prone to vibration during use.

[0030] To make the above-mentioned objects, features, and advantages of the present disclosure more clearly understood, specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present disclosure. However, the present disclosure can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present disclosure. Therefore, the present disclosure is not limited to the specific embodiments disclosed below.

[0031] In the description of the present disclosure, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure. The terms "first" and "second" are used to distinguish one element from another and do not have sequentiality or importance. In addition, when the following description refers to the drawings, the same figure marks in different drawings represent the same or similar elements, which are not repeated in this disclosure.

[0032] In this disclosure, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise expressly limited. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0033] According to some embodiments of the present disclosure, a grinding device for lubricating a bearing seat is provided, referring to Figures 1 to 13 As shown in the figure, the grinding equipment for lubricating the bearing seat processing includes a grinder housing 101, an inner wall roller 102 is provided on the grinder housing 101, a grinding motor 103 is provided in the grinder housing 101, a turntable motor 221 is provided in the grinder housing 101, a revolving turntable 201 is provided on the output shaft of the turntable motor 221, a shifting turntable 202 is rotatably installed on the revolving turntable 201, the inner wall roller 102 is rotatably installed on the shifting turntable 202, a keyway roller 203 is also provided on the shifting turntable 202, the keyway roller 203 is transmission-connected to the grinding motor 103, and when the keyway roller 203 approaches the keyway of the bearing seat, the keyway roller 203 automatically moves into the keyway.

[0034] In this way, under the premise that the inner wall roller 102 grinds the inner wall of the bearing seat, a keyway roller 203 is also provided on the shifting turntable 202. When the keyway roller 203 approaches the keyway of the bearing seat, the shifting turntable 202 rotates and shifts, and the keyway roller 203 automatically moves to the keyway for grinding, thereby realizing the synchronous grinding of the inner wall of the bearing and the keyway. Since the keyway is polished relatively smoothly, after the bearing is installed in the bearing seat, the friction between the pin on the outer wall of the bearing and the keyway is effectively reduced, thereby reducing the wear of the pin, ensuring the normal engagement of the pin and the keyway, and improving the stability of the bearing during use.

[0035] It should be noted that the inner wall roller 102 coincides with the rotation axis of the shifting turntable 202. Therefore, before and after the shifting turntable 202 is shifted, the inner wall roller 102 is always in contact with the inner wall of the bearing seat. In addition, in order to ensure that the keyway roller 203 moves smoothly to the keyway and the keyway roller 203 moves smoothly out of the keyway, please refer to Figure 1 The rotation direction of the displacement turntable 202 is opposite to the rotation direction of the revolution turntable 201.

[0036] Also, please refer to Figure 2 、 Figure 3A keyway roller shaft 204 and an inner wall roller shaft 205 are rotatably installed on the shifting turntable 202. One end of the keyway roller shaft 204 is connected to the keyway roller 203, and the other end of the keyway roller shaft 204 is equipped with a No. 1 gear 206. One end of the inner wall roller shaft 205 is connected to the inner wall roller 102, and the other end of the inner wall roller shaft 205 is equipped with a No. 2 gear 207. The No. 2 gear 207 is meshed with the No. 1 gear 206. A driving gear 208 for meshing with the No. 2 gear 207 is installed on the output shaft of the grinding motor 103.

[0037] For further information, please refer to Figure 4 、 Figure 5 In order to realize the automatic displacement of the displacement turntable 202, an annular rack 215 is provided inside the grinding machine casing 101. The annular rack 215 is configured as a segmented rack. A second rotating shaft 229 is provided on the revolving turntable 201. A displacement gear 216 for intermittently engaging with the annular rack 215 is rotatably installed on the second rotating shaft 229. An energy storage torsion spring 230 is provided on the second rotating shaft 229. One end of the energy storage torsion spring 230 is connected to the second rotating shaft 229, and the other end of the energy storage torsion spring 230 is connected to the displacement gear 216. The displacement gear 216 is transmission-connected to the displacement turntable 202. The segmented position of the annular rack 215 corresponds to the keyway of the bearing seat, ensuring that the displacement gear 216 only engages when the keyway roller 203 approaches the keyway.

[0038] It should be noted that, for every rotation of the revolution turntable 201, the shift gear 216 meshes with the annular rack 215 twice. When the shift gear 216 meshes with the annular rack 215 for the first time, the shift gear 216 rotates, and the energy storage torsion spring 230 is twisted and stored by the shift gear 216. When the shift gear 216 is not meshed with the annular rack 215, the energy storage torsion spring 230 is quickly released, and the energy storage torsion spring 230 drives the shift gear 216 to rotate in the opposite direction. At this time, the shift turntable 202 The keyway roller 203 rotates rapidly and moves into the keyway for grinding. Then the shifting gear 216 engages with the annular rack 215 for the second time, and the energy storage torsion spring 230 is twisted by the shifting gear 216 again. After the energy storage keyway roller 203 finishes grinding the keyway, the shifting gear 216 loses engagement with the annular rack 215, and the energy storage torsion spring 230 is quickly released. The energy storage torsion spring 230 drives the shifting gear 216 to rotate in the opposite direction. At this time, the shifting turntable 202 drives the keyway roller 203 to move out of the keyway.

[0039] Specifically, please refer to Figure 4 、 Figure 6 、 Figure 7A gear ring 209 is provided on the shifting turntable 202, and a No. 1 rotating shaft 225 is rotatably installed on the revolving turntable 201. The No. 1 rotating shaft 225 is provided with a one-way gear 223 for engaging with the gear ring 209. The No. 1 rotating shaft 225 is also provided with a transmission gear 217 for engaging with the shifting gear 216. A ratchet 224 is provided on the transmission gear 217, and a pawl 226 is hinged on the No. 1 rotating shaft 225. The ratchet 224 and the pawl 226 are movably engaged.

[0040] It should be noted that when the shift gear 216 is engaged with the annular rack 215, the shift gear 216 drives the transmission gear 217 to rotate. At this time, the ratchet 224 and the pawl 226 are not engaged, so the No. 1 rotating shaft 225 does not rotate. When the shift gear 216 is not engaged with the annular rack 215, the energy storage torsion spring 230 drives the shift gear 216 to rotate in the opposite direction, and the shift gear 216 drives the transmission gear 217 to rotate in the opposite direction. At this time, the ratchet 224 and the pawl 226 are engaged, and the transmission gear 217 drives the No. 1 rotating shaft 225 to rotate. At the same time, the one-way gear 223 set on the No. 1 rotating shaft 225 rotates, and the one-way gear 223 drives the shift dial 202 to shift by engaging with the gear ring 209.

[0041] In addition, when the inner wall roller 102 grinds the inner wall of the bearing seat indiscriminately, the inner wall roller 102 will cause the edge of the keyway to be rounded, affecting the engagement of the keyway and the bearing pin. In order to avoid the influence of the inner wall roller 102 on the keyway, please refer to Figure 8 The second gear 207 is rotatably mounted on the shifting turntable 202, the inner wall roller shaft 205 is slidably plugged into the second gear 207, and a key block 210 for engaging with the second gear 207 is provided on the inner wall roller shaft 205. A sleeve 214 is provided on the shifting turntable 202, and a piston rod 213 is slidably mounted in the sleeve 214. A connecting rod 211 is connected between the piston rod 213 and the inner wall roller shaft 205. A return spring 228 is provided in the sleeve 214, and the other end of the return spring 228 is in contact with the piston rod 213. When the inner wall roller 102 approaches the key slot, the inner wall roller shaft 205 and the inner wall roller 102 actively move in the direction away from the key slot (see Figure 9 ), when the inner wall roller 102 passes over the keyway, under the action of the reset compression spring 228 in the sleeve 214, the piston rod 213, the connecting rod 211, the inner wall roller shaft 205 and the inner wall roller 102 are reset.

[0042] In addition, in order to realize that the inner wall roller 102 actively moves away from the keyway, please refer to Figure 9 、 Figure 10A resistance block 212 is provided on the connecting rod 211, and the resistance block 212 is set to a spherical block. A vertical plate 218 is provided in the grinder housing 101, and a positioning rod 219 is slidably inserted on the vertical plate 218. A push plate 222 is installed at the end of the positioning rod 219 away from the vertical plate 218, and an energy storage compression spring 227 is sleeved on the positioning rod 219. The other end of the energy storage compression spring 227 is connected to the vertical plate 218. The push plate 222 intermittently conflicts with the resistance block 212, and a wedge block 220 is provided on the revolving turntable 201, and the wedge block 220 is in sliding contact with the push plate 222.

[0043] It should be noted that when the wedge block 220 contacts the push plate 222, the push plate 222 moves away from the interference block 212, and at the same time, the energy storage spring 227 is compressed and stores energy under the pressure of the push plate 222. When the wedge block 220 is separated from the push plate 222, the energy storage spring 227 is released, and the push plate 222 pushes the interference block 212 and the connecting rod 211 under the pressure of the energy storage spring 227. At the same time, the inner wall roller 205 and the inner wall roller 102 actively move away from the keyway. When the inner wall roller 102 passes the keyway, the push plate 222 disengages from the interference block 212, and under the action of the reset spring 228 in the sleeve 214, the piston rod 213, the connecting rod 211, the inner wall roller 205 and the inner wall roller 102 are reset.

[0044] Through the above technical solution, when the grinding equipment for lubricating bearing seat processing provided by the present invention is in use, the shifting gear 216 meshes with the annular rack 215 twice every time the revolving turntable 201 rotates one circle. When the shifting gear 216 meshes with the annular rack 215 for the first time, the shifting gear 216 rotates, and the energy storage torsion spring 230 is twisted and energy is stored by the shifting gear 216. When the shifting gear 216 is not meshed with the annular rack 215, the energy storage torsion spring 230 is quickly released, and the energy storage torsion spring 230 drives the shifting gear 216 to rotate in the opposite direction. At this time, the shifting turntable 202 rotates quickly, and the keyway roller 203 moves to the keyway for grinding, and then the shifting turntable 202 rotates quickly. The gear 216 is meshed with the annular rack 215 for the second time, and the energy storage torsion spring 230 is twisted by the shifting gear 216 again. After the energy storage keyway roller 203 finishes grinding the keyway, the shifting gear 216 loses meshing with the annular rack 215, and the energy storage torsion spring 230 is quickly released. The energy storage torsion spring 230 drives the shifting gear 216 to rotate in the opposite direction. At this time, the shifting turntable 202 drives the keyway roller 203 to move out of the keyway, thereby realizing automatic grinding of the bearing seat keyway. After grinding, the interior of the bearing seat is smooth, making the latch not easy to wear, ensuring the normal engagement of the keyway and the latch, and the bearing is not easy to vibrate during use, thereby improving the reliability of the device. In addition, when the wedge block 220 on the revolving turntable 201 contacts the push plate 222, the push plate 222 moves away from the interference block 212, and at the same time, the energy storage spring 227 is compressed and stores energy under the pressure of the push plate 222. When the wedge block 220 is separated from the push plate 222, the energy storage spring 227 is released, and the push plate 222 pushes the interference block 212 and the connecting rod 211 under the pressure of the energy storage spring 227. At the same time, the inner wall roller shaft 205 and the inner wall roller 102 actively move away from the keyway, thereby avoiding contact between the inner wall roller 102 and the edge of the keyway, preventing the inner wall roller 102 from causing chamfering on the edge of the keyway when grinding, which is beneficial to the normal engagement of the keyway and the pin, and further improving the reliability of the device.

[0045] It should be noted that the pawl 226 can rotate in one direction through the spring, so that the ratchet 224 can only drive the first shaft 225 to rotate in one direction through the pawl 226. The cooperation between the ratchet 224 and the pawl 226 is well known in the art and will not be elaborated here.

[0046] In some embodiments of the present disclosure, reference Figures 1 to 13 As shown in the figure, an inner wall nozzle 301 and a keyway nozzle 302 are provided on the side of the revolving turntable 201 close to the bearing seat, and a water pump 305 is provided on the side of the revolving turntable 201 away from the bearing seat. The inner wall nozzle 301 is set to be normally on, and the keyway nozzle 302 is set to be intermittently started. The water spraying direction of the inner wall nozzle 301 corresponds to the grinding position of the inner wall roller 102, and the keyway nozzle 302 is turned on only when it is located above the keyway. At this time, the keyway roller 203 is located outside the keyway, thereby preventing the keyway roller 203 from blocking and affecting the keyway nozzle 302.

[0047] For details, please refer to Figure 12 A piston cylinder 308 is provided on the revolving turntable 201, and a water inlet pipe 312 is connected between the water inlet of the piston cylinder 308 and the water pump 305, a No. 1 hose 306 is connected between the piston cylinder 308 and the inner wall nozzle 301, and the No. 1 hose 306 is connected to the water inlet pipe 312, and a No. 2 hose 307 is connected between the piston cylinder 308 and the keyway nozzle 302, and the No. 2 hose 307 is intermittently connected to the water inlet pipe 312.

[0048] Among them, please refer to Figure 12 、 Figure 13A piston plate 314 is slidably installed in the piston cylinder 308, and a pull rod 310 is installed on the side of the piston plate 314 away from the No. 1 hose 306. The connection between the No. 2 hose 307 and the water inlet pipe 312 is controlled by the displacement of the piston plate 314. The displacement of the piston plate 314 is adjusted by the stroke of the pull rod 310. When the pull rod 310 moves in the direction away from the water inlet pipe 312, the No. 2 hose 307 is connected to the water inlet pipe 312. A tension spring 311 is provided on the pull rod 310, and the other end of the tension spring 311 is connected to the piston cylinder 308. When the pull rod 310 is reset under the tension of the tension spring 311, the No. 2 hose 307 is not connected to the water inlet pipe 312.

[0049] In addition, the end of the pull rod 310 away from the piston plate 314 is hinged to the rotating plate 309, and a return torsion spring 315 is provided on the rotating plate 309. One end of the return torsion spring 315 is connected to the rotating plate 309, and the other end of the return torsion spring 315 is connected to the pull rod 310.

A resistance compression spring 313 is provided in the slide groove 304, and the other end of the resistance compression spring 313 is in contact with the slider 303. The slider 303 intermittently contacts the rotating plate 309. The slider 303 is triggered to move by the rotation of the displacement turntable 202, so that the rotating plate 309 periodically contacts the pull rod 310.

[0050] It should be noted that as the revolution turntable 201 rotates, when the keyway nozzle 302 moves to the highest position, the nozzle direction of the keyway nozzle 302 corresponds to the keyway. At this time, the slider 303 conflicts with the rotating plate 309, the rotating plate 309, the pull rod 310, and the piston plate 314 move away from the water inlet pipe 312, the No. 2 hose 307 is connected to the water inlet pipe 312, the keyway nozzle 302 is turned on, and the keyway nozzle 302 flushes the metal particles polished off the keyway. After the slider 303 moves to the maximum displacement, the rotating plate 309 deflects, and the rotating plate 309 , the pull rod 310 and the piston plate 314 are reset under the action of the tension spring 311, the No. 2 hose 307 is no longer connected to the water inlet pipe 312, and the keyway nozzle 302 is closed. At this time, the flushing is completed. The intermittent opening of the keyway nozzle 302 can clean the keyway in a targeted manner to achieve the effect of saving water. At the same time, the keyway nozzle 302 is only opened when it is above the keyway. The keyway nozzle 302 can flush the dead corners of the keyway, and the keyway roller 203 is located outside the keyway at this time, thereby preventing the keyway roller 203 from blocking the keyway nozzle 302.
