Description

Technical Field

[0001] The present application relates to the field of bearing production equipment, and in particular to a finished bearing cleaning jig capable of quickly adjusting the spray range. Background Art

[0002] Bearings are a crucial component in modern machinery. They are primarily used to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Rolling bearings typically consist of an inner ring, an outer ring coaxially positioned outside the inner ring, a cage positioned between the inner and outer rings, and several rolling elements mounted on the cage.

[0003] After the current bearing is produced, it is necessary to clean the inside of the bearing. Currently, the retaining frame is flushed through a universal bamboo tube. During operation, the universal bamboo tube needs to be manually bent according to the specifications of the bearing so that the water outlet of the universal bamboo tube is aligned with the inside of the bearing. During the cleaning process, the water outlet position of the universal bamboo tube needs to be adjusted so that the water outlet of the universal bamboo tube moves around the bearing axis to clean the bearing. Not only is cleaning inconvenient, but the cleaning effect is also poor. Summary of the Invention

[0004] In order to facilitate the cleaning of finished bearings and improve the cleaning effect, the present application provides a finished bearing cleaning jig that can quickly adjust the spray range.

[0005] The present application provides a finished bearing cleaning fixture capable of quickly adjusting the spray range, which adopts the following technical solutions:

[0006] A finished bearing cleaning jig with a quickly adjustable spray range comprises a jig body, the jig body being provided with a water inlet cavity connected to a water source via a pipe, the jig body being provided with a plurality of water diversion channels along its circumferential direction, the water diversion channels being arranged radially along the jig body, and the water inlet ends being connected to the water inlet cavity; the jig body being provided with a plurality of groups of flushing water channels along its radial direction, each group of flushing water channels being distributed along the circumferential direction of the jig body, the flushing water channels being perpendicular to the water diversion channels, the water inlet ends of the flushing water channels being connected to the water diversion channels, and the water outlet ends of the flushing water channels being connected to the outside, and a control valve for controlling the on-off of each flushing water channel being provided on the jig body.

[0007] By adopting this technical solution, the bearing to be cleaned is coaxially placed on one side of the fixture body where the flushing channel is located. A pipe is connected to the water inlet chamber, so that the water inlet chamber and the water channel are filled with water at a certain pressure. Based on the specifications of the bearing to be cleaned, the control valve opens a set of flushing channels facing the retainer and closes the remaining flushing channels, preventing water pressure loss and allowing the open flushing channels to flush the bearing. Quickly adjusting the spray range according to the bearing specifications not only facilitates the cleaning of finished bearings, but also improves the cleaning effect of finished bearings.

[0008] Optionally, the fixture body is arranged horizontally, and a flow channel with a diameter larger than itself is opened at the water inlet end of the flushing water channel. A mounting hole is coaxially arranged on the fixture body corresponding to each flow channel, and the mounting hole is located on the side of the water diversion channel away from the flushing water channel. The control valve includes a sphere arranged at the water outlet end of the flow channel, a mounting seat arranged inside the mounting hole, and a magnet rod slidably arranged on the mounting seat. The diameter of the sphere is larger than the diameter of the flushing water channel, and the magnet rod slides axially along the flow channel.

[0009] By adopting this technical solution, the fixture body is positioned horizontally. When the bottom end of the magnet bar contacts the sphere, the sphere, under the combined forces of its own weight, the gravity of the water flow, and the pressure of the magnet bar, blocks the outlet of the flow channel, thereby closing the flushing channel. As the magnet bar slides upward, the sphere is attracted to the magnet bar, creating a gap between the sphere and the outlet of the flow channel, allowing water to flow through. This opens the flushing channel and allows the finished bearing to be rinsed. Once the flushing is complete, the magnet bar slides downward to reset, and the sphere blocks the outlet of the flow channel.

[0010] Optionally, a screw is provided at one end of the mounting seat, and the screw is threadedly connected to the mounting hole.

[0011] By adopting the above technical solution, the screw rod is threadedly connected to the mounting hole, thereby facilitating the disassembly and assembly of the mounting seat, thereby replacing the mounting seat and the matching magnet rod.

[0012] Optionally, the mounting hole is a stepped hole, and a plurality of first sealing rings are provided on the steps inside the mounting hole. The end of the screw contacts the first sealing ring, and the magnet rod passes through the first sealing ring and interferes with the inner ring of the first sealing ring.

[0013] By adopting the above technical solution, the end of the screw contacts the first sealing ring, thereby sealing the connection between the mounting hole and the screw, reducing the possibility of water leakage at the mounting hole. At the same time, the magnet rod passes through the interior of the first sealing ring, and the inner ring of the first sealing ring and the magnet rod interfere to achieve sealing.

[0014] Optionally, the inner wall of the flow channel is provided with a limit block for limiting the sphere, and several limit blocks are provided along the circumferential direction of the flow channel. The surface of the limit block facing away from the side wall of the flow channel is arranged in an arc shape, and a channel no larger than the diameter of the sphere is formed between the several limit blocks.

[0015] By adopting the above technical solution, the volume of the sphere will shrink after being frozen. The frozen sphere can be placed into the water outlet end of the flow channel through the channel formed between several limit blocks. After the sphere is assembled, the temperature rises and its own volume becomes larger. Even if the magnet rod is pulled out, the sphere is not easy to fall out of the flow channel.

[0016] Optionally, a mounting groove is provided at the opening of the water inlet cavity, a sealing plate is detachably connected to the inside of the mounting groove, and a connecting port for connecting a water pipe is provided on the sealing plate.

[0017] By adopting the above technical solution, a sealing plate is detachably connected inside the installation groove to achieve sealing of the water inlet cavity, so that a sealed space is formed inside the water inlet cavity.

[0018] Optionally, a sealing protrusion is provided on one side of the sealing plate, the sealing protrusion is plugged into and matched with the water inlet cavity, and the side wall of the sealing protrusion is in contact with the side wall of the water inlet cavity.

[0019] By adopting the above technical solution, the sealing protrusion is inserted into the water inlet cavity and fits against the side wall of the water inlet cavity, thereby improving the sealing performance between the sealing protrusion and the water inlet cavity and reducing the possibility of water leakage inside the water inlet cavity.

[0020] Optionally, a sealing chamfer is provided at the step between the water inlet cavity and the mounting groove, a second sealing ring is sleeved on the outside of the sealing protrusion, and the second sealing ring is located in the space between the sealing chamfer and the sealing plate.

[0021] By adopting the above technical solution, after the sealing plate is installed, the second sealing ring will be used to squeeze the sealing chamfer, and the space between the sealing chamfer and the sealing plate will be filled through the deformation of the second sealing ring itself, thereby further improving the sealing inside the water inlet chamber and the water pressure bearing capacity inside the water inlet chamber, which helps to improve the flushing effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. During use, the bearing to be cleaned is coaxially placed on the side of the fixture body where the flushing channel is located. A pipe is connected to the water inlet chamber, so that the water inlet chamber and the water channel are filled with water at a certain pressure. Depending on the specifications of the bearing to be cleaned, the control valve controls the opening of a group of flushing channels facing the retainer or a portion of the flushing channels in a group, while the remaining flushing channels are closed to prevent water pressure loss. This allows the open flushing channels to flush the bearing. Ultimately, this not only facilitates the cleaning of finished bearings, but also improves the cleaning effect of finished bearings.

[0024] 2. The fixture is positioned horizontally. When the bottom end of the magnet bar contacts the sphere, the sphere blocks the outlet of the flow channel due to its own weight, the gravity of the water flow, and the pressure of the magnet bar, thereby closing the flushing channel. As the magnet bar slides upward, the sphere is attracted to the magnet bar, creating a gap between the sphere and the outlet of the flow channel, allowing water to flow through. This opens the flushing channel and allows the finished bearing to be flushed. After flushing is complete, the magnet bar slides downward to reset, and the sphere blocks the outlet of the flow channel.

[0025] 3. After the sealing plate is installed, the second sealing ring will squeeze the sealing chamfer, and the second sealing ring will deform to fill the space between the sealing chamfer and the sealing plate, thereby further improving the sealing inside the water inlet cavity and the water pressure bearing capacity inside the water inlet cavity, which helps to improve the flushing effect.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a finished bearing cleaning jig with a rapidly adjustable spray range.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 A finished bearing cleaning jig with a quickly adjustable spray range includes a jig body 1, which is a horizontally arranged cylindrical shape. A water inlet chamber 11 is coaxially opened at the center position of the top of the jig body 1, and the opening of the water inlet chamber 11 is sealed by a sealing plate 3. A plurality of water diversion channels 12 are opened on the side wall of the water inlet chamber 11 along its circumferential direction. In this embodiment, six water diversion channels 12 are taken as an example. Each water diversion channel 12 is arranged radially along the jig body 1, and the water inlet end of the water diversion channel 12 is connected to the water inlet chamber 11. A plurality of flushing water channels 13 connected to the water diversion channels 12 are arranged at the bottom of the jig body 1, and a control valve 2 ( Figure 1 Take one as an example).

[0035] Reference Figure 1 and Figure 3 , connecting the water inlet chamber 11 via a pipe, allowing water under a certain pressure to flow into the water inlet chamber 11 and the water diversion channel 12. Before rinsing, the bearing to be cleaned is coaxially placed below the fixture body 1. Depending on the specifications of the bearing to be cleaned, the control valve 2 opens the flushing channel 13 facing the retainer and closes the remaining flushing channels 13, thereby flushing the bearing in focus. Quickly adjusting the spray range according to the bearing specifications not only facilitates the cleaning of finished bearings, but also improves the cleaning effect.

[0036] Reference Figure 1 A circular mounting groove 111 is coaxially opened at the opening of the water inlet chamber 11, and the sealing plate 3 is embedded in the mounting groove 111. The sealing plate 3 is flush with the fixture body 1. The sealing plate 3 and the fixture body 1 are detachably connected. In this embodiment, the detachable method is bolt connection as an example. A connecting port 31 is opened in the center of the sealing plate 3, and an internal thread is provided at the connecting port 31 for convenient threaded connection of the water pipe.

[0037] Reference Figure 1In order to ensure the sealing of the water inlet chamber 11, a sealing protrusion 32 is integrally formed on one side of the sealing plate 3. The sealing protrusion 32 is plugged into the water inlet chamber 11, and the side wall of the sealing protrusion 32 is in contact with the side wall of the water inlet chamber 11, so that the sealing protrusion 32 seals the water inlet chamber 11. A sealing chamfer 112 is machined at the step between the water inlet chamber 11 and the mounting groove 111. The sealing chamfer 112 is a 45-degree straight chamfer. A second sealing ring 42 is sleeved on the outside of the sealing protrusion 32. When the sealing plate 3 is placed in the mounting groove 111, the second sealing ring 42 is pressed tightly into the space between the sealing chamfer 112 and the sealing plate 3, causing the second sealing ring 42 to deform and fill the space between the sealing chamfer 112 and the sealing plate 3, thereby improving the sealing of the water inlet chamber 11.

[0038] Reference Figure 3 The flushing channels 13 are vertically arranged, with the top of the flushing channels 13 communicating with the water diversion channel 12 and the bottom communicating with the outside. Several groups of flushing channels 13 are radially arranged along the fixture body 1. This embodiment uses six groups as an example. Each group of flushing channels 13 is arranged circumferentially along the fixture body 1, and each group of flushing channels 13 corresponds to a specific specification of bearing. During flushing, one group of flushing channels 13 or part of a group of flushing channels 13 is opened, and the remaining flushing channels 13 are closed.

[0039] Reference Figure 4 A flow channel 131 with a diameter larger than itself is provided at the water inlet end of each flushing water channel 13. A mounting hole 14 is coaxially provided on the top of the fixture body 1 corresponding to each flow channel 131. The mounting hole 14 is connected to the water diversion channel 12 and is a stepped hole.

[0040] Reference Figure 1 and Figure 4 The control valve 2 includes a sphere 21, a mounting seat 22, and a magnet rod 23. The sphere 21 is arranged at the outlet end of the flow channel 131. The outlet end of the flow channel 131 is arranged in a conical surface. The diameter of the flow channel 131 is larger than the diameter of the sphere 21. The diameter of the sphere 21 is larger than the diameter of the flushing water channel 13, so that the sphere 21 blocks the outlet end of the flow channel 131 under the action of gravity. The mounting seat 22 is a hexagonal column. A screw 221 is integrally formed at one end of the mounting seat 22. The screw 221 is threadedly connected to the mounting hole 14. In order to ensure the sealing performance at the mounting hole 14, a plurality of first sealing rings 41 are placed on the stepped surface inside the mounting hole 14. In this embodiment, two are taken as an example. When the screw 221 is tightened, the end of the screw 221 conflicts with the first sealing ring 41.

[0041] Reference Figure 1 and Figure 4Magnet rod 23 is coaxially arranged with flow channel 131 and slides through mounting base 22. The bottom end of magnet rod 23 contacts sphere 21. Magnet rod 23 is a neodymium magnet. Neodymium magnets are tetragonal crystals composed of neodymium, iron, and boron, and have excellent magnetic properties, improving operational stability. Magnet rod 23 interferes with the inner ring of first sealing ring 41, achieving a seal.

[0042] Reference Figure 1 and Figure 4 When the magnet bar 23 contacts the sphere 21, the sphere 21 blocks the outlet of the flow channel 131 due to the combined effects of its own weight, the water pressure, and the magnet bar 23, and the flushing water channel 13 is closed. When the magnet bar 23 slides upward, the sphere 21 is attracted by the magnet bar 23, creating a gap between the sphere 21 and the outlet of the flow channel 131 for water to flow through. The flushing water channel 13 is opened, allowing the finished bearing to be flushed. After flushing is completed, the magnet bar 23 slides downward, causing the sphere 21 to return to its original position, blocking the outlet of the flow channel 131.

[0043] Reference Figure 1 and Figure 4 A plurality of limit blocks 132 are integrally formed on the inner wall of flow channel 131. In this embodiment, two limit blocks 132 are provided along the circumference of flow channel 131. The surfaces of the limit blocks 132 facing away from the sidewall of flow channel 131 are curved. A channel for spherical body 21 is formed between the two limit blocks 132. The diameter of the channel matches that of spherical body 21. After being frozen, spherical body 21 is reduced in volume and then placed through the channel into the outlet of flow channel 131. After assembly, spherical body 21 heats up and expands in volume. Even if magnet rod 23 is removed, spherical body 21 is unlikely to fall out of flow channel 131.

[0044] The implementation principle of the finished bearing cleaning jig with a rapidly adjustable spray range according to the embodiment of the present application is as follows: a water pipe is connected to the sealing plate 3 to allow water with a certain pressure to flow into the water inlet chamber 11 and the water diversion channel 12. Before flushing, the bearing to be cleaned is coaxially placed below the jig body 1. At this time, all the flushing water channels 13 are in a closed state. According to the specifications of the bearing to be flushed, the flushing water channel 13 facing the retaining frame is controlled to open. When opened, the corresponding magnet rod 23 slides downward and approaches the sphere 21. When the sphere 21 is adsorbed by the magnet rod 23, a gap is generated between the sphere 21 and the water outlet end of the flow channel 131 for water to flow through. The flushing water channel 13 is opened to clean the finished bearing. After flushing is completed, the magnet rod 23 slides upward, and the sphere 21 is reset under the action of its own gravity and the action of the water flow, blocking the water outlet end of the flow channel 131, completing the cleaning process of the finished bearing.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
