Description

Technical Field

[0001] This application relates to the field of bearing technology, and in particular to a grinding device for a bearing cage. Background Technology

[0002] In the production process of bearing cages, a vibratory grinder is usually used to grind and polish the bearing cages. The bearing cages are usually poured directly into the grinding media of the vibratory grinder, and the grinding is completed by the friction between the grinding media and the cage through the vibration of the vibratory grinder. Finally, the bearing cages in the grinding media are manually removed. However, the bearing cages are scattered in the grinding media, which makes the collection process time-consuming and labor-intensive. Summary of the Invention

[0003] To overcome the drawback of bearing cages being scattered within the grinding media, resulting in a time-consuming and labor-intensive collection process, this invention provides a mesh cylinder grinding device for bearing cages.

[0004] Technical Solution: A grinding device for a bearing cage includes a base plate and a vibrating frame. The vibrating frame is connected to the base plate via a vibrating assembly, and the vibrating frame is filled with grinding media. The vibrating assembly consists of a vibrating motor and several supporting springs, and is used to drive the vibrating frame to vibrate. An opening and closing part is detachably connected to the lower rear of the vibrating frame. The device also includes a mounting column 1, a connecting rod, a mounting column 2, a partition plate, a grinding cylinder, locking blocks, protruding rods, and a cylinder 1. Several mounting columns 1 are placed inside the vibrating frame. A connecting rod is fixedly connected to the middle of each mounting column 1. A mounting column 2 is screwed onto each connecting rod. The grinding cylinder is slidably connected between mounting columns 1 and 2. Several locking blocks are equidistantly fixed to the left side of the mounting column 2. A partition plate is slidably connected inside the vibrating frame, and the front and rear of the partition plate are both arc-shaped. Several protruding rods are equidistantly fixed to the partition plate. A cylinder 1 is fixedly connected to the left and right sides of the base plate. The extension and retraction ends of both cylinders 1 are in contact with the partition plate.

[0005] Furthermore, it is particularly preferred that the bottom of the vibrating frame is inclined, with the rear lower than the front.

[0006] In addition, it is particularly preferred that it also includes a second cylinder and a first baffle; two second cylinders are fixedly connected to the base plate; and a first baffle is fixedly connected to the extension and retraction ends of the two second cylinders respectively.

[0007] Furthermore, it is particularly preferred that the lower part of the baffle is cone-shaped.

[0008] Furthermore, it is particularly preferred that the outer surface of the connecting rod be made of an abrasive material.

[0009] Furthermore, it is particularly preferred that the plate also includes hooks; each of the two baffles is fixedly attached with a hook.

[0010] Furthermore, it is particularly preferred that the vibrating frame also includes a toggle block; a toggle block is fixedly attached to the left side and the right side of the vibrating frame respectively.

[0011] Furthermore, it is particularly preferred that it also includes cylinder three and baffle two; several cylinder three are fixedly connected to the front of the base plate; and baffle two is fixedly connected to the telescopic ends of all cylinder three.

[0012] Furthermore, it is particularly preferred that the lower part of the second baffle is cone-shaped.

[0013] Furthermore, it is particularly preferred that several air pipes are equidistantly arranged inside the baffle, with the air nozzles of the air pipes angled downwards and backwards.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a storage cylinder composed of a first mounting column, a second mounting column, a mesh cylinder, a clamping block, and a connecting rod to place the bearing cage. The grinding medium can contact and rub against the bearing cage inside the mesh cylinder through the through hole, thereby grinding and polishing the bearing cage. The grinding effect is no different from grinding the bearing cage directly in the grinding medium. After grinding, simply remove the storage cylinder and then remove the bearing cage from the connecting rod. This facilitates convenient and quick collection of the bearing cage and effectively improves the grinding efficiency of the cage.

[0015] 2. During the grinding process, the two cylinders are controlled to extend and retract back and forth, thereby driving the partition plate and the convex rod to move back and forth left and right. This causes the mesh cylinder and the grinding medium to move relative to each other, making it easier for the grinding medium to enter and exit the mesh cylinder, increasing the contact friction frequency between the grinding medium and the bearing cage, and enhancing the grinding effect.

[0016] 3. In this invention, the storage cylinder is removed from the grinding medium by a hook, so that the storage cylinder is moved above the vibration frame, which facilitates manual observation of the grinding condition of the bearing cage inside the storage cylinder. After the storage cylinder is moved above the vibration frame, the storage cylinder is located behind the air outlet of the air pipe. The air pipe is connected to an air pump in advance, and then the air pump is started, so that high-pressure gas is sprayed through the air pipe onto the bearing cage inside the storage cylinder to remove the residual grinding agent on the bearing cage, thereby facilitating manual observation of the grinding condition.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0025] Example 1

[0026] A grinding device for a bearing cage, such as Figures 1-6 As shown, it includes a base plate 1 and a vibrating frame 2; the vibrating frame 2 is connected to the base plate 1 via a vibrating assembly, and the vibrating frame 2 is filled with grinding media; the lower rear part of the vibrating frame 2 is detachably connected to an opening and closing part 201.

[0027] It also includes mounting posts 3, connecting rods 31, mounting posts 4, partition plates 7, mesh cylinders 8, locking blocks 9, protruding rods 10, and cylinders 11; four mounting posts 3 are placed inside the vibration frame 2; a connecting rod 31 is welded to the middle part of each mounting post 3; a mounting post 4 is screwed to the right side of each connecting rod 31; a mesh cylinder 8 is slidably connected between mounting posts 3 and mounting posts 4; several locking blocks 9 are welded at equal intervals to the left side of mounting posts 4; a partition plate 7 is slidably connected inside the vibration frame 2, and the front and rear parts of the partition plate 7 are both arc-shaped; several protruding rods 10 are welded at equal intervals on the partition plate 7; a cylinder 11 is fixed to the left and right sides of the base plate 1; the telescopic ends of the two cylinders 11 are in contact with the partition plate 7.

[0028] To facilitate the movement of the grinding media, the bottom of the vibrating frame 2 is inclined, with the rear lower than the front.

[0029] It also includes cylinder 25 and baffle 16; two cylinders 25 are fixedly connected to the base plate 1; and a baffle 16 is fixedly connected to the extension and retraction ends of the two cylinders 25 respectively.

[0030] To facilitate insertion into the grinding media, the lower part of the baffle 6 is designed to be conical.

[0031] In order to grind the inner side of the bearing cage, the outer surface of the connecting rod 31 is made of a grinding material.

[0032] The second mounting column 4 is manually unscrewed from the connecting rod 31. The second mounting column 4, via the locking block 9, moves the mesh cylinder 8 and separates from the first mounting column 3, exposing the connecting rod 31. Then, the bearing cage is fitted onto the connecting rod 31, and the second mounting column 4 is screwed back onto it. The first mounting column 3, the second mounting column 4, the mesh cylinder 8, the locking block 9, the connecting rod 31, and the bearing cage inside are then placed into the vibrating frame 2. Next, the vibration assembly on the base plate 1 is activated, causing the vibrating frame 2 to vibrate. The vibration energy generated by the vibration motor is transferred to the vibrating frame 2, causing it to vibrate at high frequency on the support spring, thereby driving... The internal grinding media moves clockwise within the vibrating frame 2, based on a right-to-left viewing angle. This clockwise movement of the grinding media causes the mounting posts 3, 4, 8, 9, 31, and the bearing cage to move together. The 8 has through holes, allowing the grinding media to contact and rub against the bearing cage, thus polishing it. The polishing effect is identical to grinding the bearing cage directly within the grinding media. Multiple mounting posts 3, 4, and 9 can be placed simultaneously within the vibrating frame 2. The storage cylinder, composed of cylinder 8, clamping block 9, and connecting rod 31, can grind multiple sets of bearing cages at once. After grinding, the control cylinder 2 5 drives the baffle 1 6 to descend, causing the baffle 1 6 to insert into the rear of the grinding medium, thus blocking the movement of the mounting post 1 3. In this way, the storage cylinder (hereinafter referred to as the storage cylinder for convenience) composed of mounting post 1 3, mounting post 2 4, mesh cylinder 8, clamping block 9, and connecting rod 31 is blocked by the baffle 1 6 and exposed above the grinding medium, facilitating its removal. The storage cylinder is then manually removed, and mounting post 2 4 is unscrewed from the connecting rod 31. The second 4 uses the locking block 9 to move the mesh cylinder 8 and separate it from the mounting column 3, exposing the connecting rod 31. Then, the bearing cage can be removed from the connecting rod 31. This facilitates the quick and easy collection of bearing cages and effectively improves the grinding efficiency of the cages. Moreover, different batches of bearing cages can be placed in each storage cylinder and marked on the storage cylinders, so that different batches of bearings can be ground simultaneously. When the bearing cage in a storage cylinder is ground, simply remove the storage cylinder and the bearing cage can be removed. The bearing cages in the other storage cylinders can continue to be ground without being affected.

[0033] When multiple storage cylinders containing bearing cages are placed in the vibrating frame 2 for grinding, there is a possibility that the cylinders may stack together and become stuck, affecting the movement of the grinding media and reducing the grinding efficiency of the media on the bearing cage. Therefore, a partition plate 7 is provided inside the vibrating frame 2, so that the storage cylinders and grinding media move clockwise around the outer surface of the partition plate 7. Figure 4 As shown, the distance between the lower side of the partition plate 7 and the lower side of the inner side of the vibration frame 2, the distance between the front side of the partition plate 7 and the front side of the inner side of the vibration frame 2, and the distance between the rear side of the partition plate 7 and the rear side of the inner side of the vibration frame 2 are all only enough for one storage cylinder to pass through. This avoids the storage cylinders from being stacked together and getting stuck, thereby avoiding a reduction in the grinding efficiency of the grinding media on the bearing cage.

[0034] During grinding, the mesh cylinder 8 affects the movement of the grinding media and its contact with the bearing cage inside, resulting in reduced grinding efficiency. Therefore, during the grinding process, the two cylinders 11 are controlled to extend and retract back and forth, driving the partition plate 7 and the protruding rod 10 to move left and right back and forth. The distance between the lower side of the partition plate 7 and the lower side of the vibrating frame 2 is only enough for one storage cylinder to pass through. When the storage cylinder moves to the lower side of the partition plate 7 and the vibrating frame 2, the protruding rod 10 will insert into the mesh cylinder 8 through the mesh. Subsequently, when the storage cylinder moves to the upper side of the partition plate 7, the protruding rod 10 on the upper side of the partition plate 7 will also insert into the mesh cylinder 8 through the mesh. Inside, as the partition plate 7 and the protruding rod 10 move back and forth, the protruding rod 10 drives the storage cylinder to move through the mesh cylinder 8. When it moves to the point where the mounting column 1 3 or mounting column 2 4 contacts the inner wall of the vibration frame 2, the mounting column 1 3, mounting column 2 4 and connecting rod 31 stop moving, while the mesh cylinder 8 continues to be driven to move by the protruding rod 10 until the mesh cylinder 8 contacts the mounting column 1 3 or mounting column 2 4. This causes the mesh cylinder 8 and the grinding medium to undergo relative displacement, making it easier for the grinding medium to enter and exit the mesh cylinder 8, increasing the contact friction frequency between the grinding medium and the bearing cage, and enhancing the grinding effect.

[0035] Example 2

[0036] Based on Example 1, such as Figure 4 As shown, it also includes a hook 21; a hook 21 is fixedly attached to the middle of the front side of each of the two baffles 6.

[0037] It also includes a toggle block 22; a toggle block 22 is welded to the left side and the right side of the vibrating frame 2 respectively.

[0038] To ensure the grinding effect of the bearing cage and prevent over-grinding, the grinding process needs to be observed. When observation is required, control cylinder 25 lowers baffle 6 and hook 21 until hook 21 is aligned with the middle of the storage cylinder above partition plate 7. When the storage cylinder contacts hook 21, hook 21 inserts into the through hole of mesh cylinder 8, thus hooking the storage cylinder. Then, control cylinder 25 moves baffle 6, hook 21, and the hooked storage cylinder upwards, removing them from the grinding medium and positioning the storage cylinder behind the actuating block 22. Most of the grinding medium in the storage cylinder falls back into the vibrating frame 2 through the through hole, while a small portion of the grinding medium remains in the vibrating frame 2 and the shaft. Between the bearing cage and the vibrating frame 2, when the vibrating frame 2 vibrates, it will drive the actuating block 22 to vibrate as well. When the actuating block 22 vibrates, it will actuate the storage cylinder on the hook 21, causing the mounting column 3 to shake. This will cause the grinding medium remaining between the vibrating frame 2 and the bearing cage in the storage cylinder to be shaken off. Then, the cylinder 2 5 will be controlled to drive the baffle 1 6, the hook 21 and the storage cylinder hooked on it to move upward, so that the storage cylinder moves above the vibrating frame 2, so that the grinding condition of the bearing cage in the storage cylinder can be observed manually. Then, the manual can observe the grinding condition of the bearing cage through the through hole on the mesh cylinder 8, or directly unscrew the mounting column 2 4 and directly take out the bearing cage for observation. After observation, if grinding is still required, the storage cylinder can be put back into the vibrating frame 2.

[0039] Example 3

[0040] Based on Example 2, such as Figures 3-4 As shown, it also includes cylinder 3 41 and baffle 2 42; two cylinder 3 41 are fixedly connected to the front of the base plate 1; all the telescopic ends of cylinder 3 41 are fixedly connected to baffle 2 42.

[0041] To facilitate insertion into the grinding media, the lower part of the baffle 42 is designed to be conical.

[0042] Several air pipes 43 are equidistantly arranged inside the baffle 42, and the air nozzles of the air pipes 43 are set obliquely to the rear and lower.

[0043] When the storage cylinder is placed into the vibrating frame 2, the grinding media prevents it from being placed directly near the partition plate 7, meaning the storage cylinder is exposed above the grinding media. This makes it difficult for the grinding media to carry the storage cylinder between the partition plate 7 and the lower part of the vibrating frame 2, thus hindering the movement of the storage cylinder around the surface of the partition plate 7. Consequently, the protrusion 10 on the partition plate 7 cannot drive the mesh cylinder 8 to move relative to the grinding media, thus failing to enhance the grinding effect. Therefore, when the storage cylinder is placed back into the vibrating frame 2, the cylinder 3 41 is first controlled to move the baffle 2 42 downwards, allowing the baffle 2 42 to insert into the vibrating frame 2. This arrangement positions the second baffle 42 in front of the partition plate 7, blocking the movement of the grinding media in front of it. The grinding media behind the second baffle 42 continues to move backward and accumulates at the rear of the vibration frame 2, reducing the amount of grinding media on the upper side of the partition plate 7 near the rear of the second baffle 42. Then, the storage cylinder is placed in, bringing it as close to the partition plate 7 as possible, so that the grinding media can carry the storage cylinder between the partition plate 7 and the lower inner side of the vibration frame 2. This allows the protruding rod 10 on the partition plate 7 to cause relative displacement between the mesh cylinder 8 and the grinding media, enhancing the grinding effect. After placement, the cylinder 3 41 is controlled to move the second baffle 42 upward to reset it.

[0044] To enhance the grinding effect, abrasives containing surfactants are usually added to the grinding media. During the grinding process, a large amount of foam is generated. As a result, after the storage cylinder moves above the vibrating frame 2, foam adheres to the bearing cage, making it difficult to observe the grinding process manually. Therefore, an air pipe 43 is provided, which is pre-connected to an air pump. After the storage cylinder moves above the vibrating frame 2, the storage cylinder is located behind the air outlet of the air pipe 43. Then, the air pump is started, so that high-pressure gas is sprayed through the air pipe 43 onto the bearing cage inside the storage cylinder, removing the residual foam on the bearing cage and making it easier to observe the grinding process manually.

[0045] After prolonged use, the grinding media needs to be replaced. A collection box is placed below the rear of the vibrating frame 2 beforehand. Then, the opening and closing part 201 is removed, allowing the grinding media inside the vibrating frame 2 to flow into the collection box for collection. Some grinding media will remain at the bottom of the vibrating frame 2. Since there is a partition plate 7 inside the vibrating frame 2, the grinding media located below the partition plate 7 is not easy to clean manually. By controlling the cylinder 3 41 to move the baffle 2 42 downward, the lower side of the baffle 2 42 is close to the bottom of the vibrating frame 2. Then, the air pump is started, and high-pressure gas is sprayed through the air pipe 43 to the bottom of the vibrating frame 2, thus blowing the grinding media remaining at the bottom of the vibrating frame 2 into the collection box for collection. Then, the cylinder 3 41 is controlled to move the baffle 2 42 upward and reset it, and the opening and closing part 201 is reinstalled into the vibrating frame 2. Finally, new grinding media is poured in to complete the replacement of the grinding media.

[0046] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
