[0005] In addition, it is particularly preferred that the bottom of the vibration frame is inclined, with the rear portion being lower than the front portion.

[0006] In addition, it is particularly preferred that it also includes a cylinder 2 and a baffle 1; two cylinders 2 are fixedly connected to the bottom plate; and a baffle 1 is fixedly connected to the telescopic ends of the two cylinders 2 respectively.

[0007] Furthermore, it is particularly preferred that a lower portion of the baffle is configured to be conical.

[0008] Furthermore, it is particularly preferred that the outer surface of the connecting rod is configured to be a ground material.

[0009] In addition, it is particularly preferred that a hook is further included; one hook is fixedly connected to each of the two baffles.

[0010] In addition, it is particularly preferred that a toggle block is further included; a toggle block is fixedly connected to the left side and the right side of the vibration frame respectively.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0025] Example 1

[0026] A mesh cylinder grinding device for a bearing retainer, such as Figure 1-Figure 6 As shown, it includes a bottom plate 1 and a vibration frame 2; the bottom plate 1 is connected to the vibration frame 2 through a vibration component, and the vibration frame 2 is filled with grinding media; the lower rear portion of the vibration frame 2 is detachably connected to an opening and closing portion 201;

[0027] It also includes a mounting column 1 3, a connecting rod 31, a mounting column 2 4, a partition plate 7, a net tube 8, a block 9, a protruding rod 10 and a cylinder 11; four mounting columns 3 are placed in the vibration frame 2; a connecting rod 31 is welded in the middle of each mounting column 3; a mounting column 2 4 is screwed to the right of each connecting rod 31; a net tube 8 is slidably connected between the mounting column 1 3 and the mounting column 2 4; a number of blocks 9 are equidistantly welded to the left of the mounting column 2 ; a partition plate 7 is slidably connected in the vibration frame 2, and the front and rear parts of the partition plate 7 are both arranged in an arc shape; a number of protruding rods 10 are equidistantly welded on the partition plate 7; a cylinder 11 is fixedly connected to the left and right parts of the bottom plate 1; the telescopic ends of the two cylinders 11 are in contact with the partition plate 7.

[0028] In order to facilitate the movement of the grinding medium, the bottom of the vibration frame 2 is inclined, with the rear portion being lower than the front portion.

[0029] It also includes a cylinder 2 5 and a baffle 1 6; two cylinders 2 5 are fixedly connected to the bottom plate 1; and a baffle 1 6 is fixedly connected to the telescopic ends of the two cylinders 2 5 respectively.

[0030] In order to facilitate insertion into the grinding medium, the lower part of the baffle 6 is set to be conical.

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

[0032] Manually unscrew the mounting column 2 4 from the connecting rod 31, and the mounting column 2 4 moves with the net tube 8 through the clamping block 9 to separate from the mounting column 1 3, so that the connecting rod 31 is exposed, and then the bearing retainer is sleeved on the connecting rod 31, and then the mounting column 2 4 is screwed on the connecting rod 31, and then the mounting column 1 3, the mounting column 2 4, the net tube 8, the clamping block 9, the connecting rod 31 and the bearing retainer inside are placed into the vibration frame 2, and then the vibration assembly on the bottom plate 1 is started to drive the vibration frame 2 to vibrate, and the vibration energy generated by the vibration motor is transmitted to the vibration frame 2, so that the vibration frame 2 generates high-frequency vibration on the supporting spring, thereby driving The grinding medium inside moves, with the view from right to left as the reference, so that the grinding medium in the vibration frame 2 moves clockwise. When the grinding medium moves clockwise, it will drive the mounting column 1 3, the mounting column 2 4, the net tube 8, the block 9, the connecting rod 31 and the bearing retainer inside to move together. The net tube 8 is provided with a through hole, and the grinding medium can pass through the through hole to contact and rub with the bearing retainer in the net tube 8, thereby grinding and polishing the bearing retainer. The grinding effect is the same as that of directly placing the bearing retainer in the grinding medium for grinding. Multiple mounting columns 1 3, mounting columns 2 4, net tubes 8, block blocks 9, connecting rods 31 and the bearing retainer inside can be placed in the vibration frame 2 at the same time. The storage cylinder composed of the cylinder 8, the block 9 and the connecting rod 31 can grind multiple groups of bearing retainers at one time; after grinding, the control cylinder 25 drives the baffle 6 to descend, so that the baffle 6 is inserted into the rear part of the grinding medium to block the movement of the mounting column 3, so that the storage cylinder composed of the mounting column 3, the mounting column 24, the net cylinder 8, the block 9 and the connecting rod 31 (hereinafter referred to as the storage cylinder for the convenience of description) is blocked by the baffle 6 when moving, and is exposed on the upper part of the grinding medium, so that the storage cylinder is taken out manually, and then the mounting column 24 is unscrewed from the connecting rod 31, and the mounting column 24 is removed. The second 4 moves with the net tube 8 through the clamping block 9 and separates from the mounting column 3, so that the connecting rod 31 is exposed, and then the bearing retainer can be removed from the connecting rod 31, which is conducive to the convenient and rapid collection of the bearing retainers, and effectively improves the grinding efficiency of the retainers; and different batches of bearing retainers can be placed in each storage tube, and marks can be made on the storage tube, so that different batches of bearings can be ground at the same time. When the bearing retainer in a storage tube is ground, it is only necessary to take out the bearing retainer from the storage tube, and the bearing retainers in the other storage tubes continue to be ground without being affected.

[0033] When multiple storage cartridges equipped with bearing retainers are placed in the vibration frame 2 for grinding, there is a situation where multiple storage cartridges are stacked together and stuck, which in turn affects the movement of the grinding media, resulting in a decrease in the grinding efficiency of the grinding media on the bearing retainer; therefore, a partition plate 7 is provided in the vibration frame 2, so that the storage cartridges and the grinding media move clockwise around the outer surface of the partition plate 7, such as Figure 4 As shown, the distance between the lower side of the partition plate 7 and the inner lower side of the vibration frame 2, the distance between the front side of the partition plate 7 and the inner front side of the vibration frame 2, and the distance between the rear side of the partition plate 7 and the inner rear side of the vibration frame 2 are all sufficient for only one storage cartridge to pass through, thereby preventing the storage cartridges from being stacked together and getting stuck, thereby preventing the grinding efficiency of the bearing retainer from being reduced due to the grinding medium.

[0034] During grinding, the mesh tube 8 will affect the movement of the grinding medium and the contact with the bearing retainer inside it, resulting in reduced grinding efficiency; therefore, during the grinding process, the two cylinders 11 are controlled to extend and retract back and forth to drive the partition plate 7 and the protruding rod 10 to move back and forth. The distance between the lower side of the partition plate 7 and the lower inner side of the vibration frame 2 is only enough for one storage tube to pass through. When the storage tube moves to the lower inner side of the partition plate 7 and the vibration frame 2, the protruding rod 10 will be inserted into the mesh tube 8 through the mesh. When the storage tube is subsequently moved to the upper side of the partition plate 7, the protruding rod 10 on the upper side of the partition plate 7 will also be inserted into the mesh tube 8 through the mesh. When the partition plate 7 and the protruding rod 10 move back and forth left and right, the protruding rod 10 drives the storage cylinder to move through the net cylinder 8. When it moves to the mounting column 1 3 or the mounting column 2 4 and contacts the inner wall of the vibration frame 2, the mounting column 1 3, the mounting column 2 4 and the connecting rod 31 no longer move, and the net cylinder 8 continues to be driven by the protruding rod 10 to move until the net cylinder 8 contacts the mounting column 1 3 or the mounting column 2 4. In this way, the net cylinder 8 and the grinding medium are relatively displaced, making it easier for the grinding medium to enter and exit the net cylinder 8, thereby increasing the contact friction frequency between the grinding medium and the bearing retainer and enhancing the grinding effect.

[0035] Example 2

[0036] On the basis of Example 1, Figure 4 As shown, a hook 21 is also included; a hook 21 is fixedly connected to the middle of the front side of each of the two baffles 6.

[0037] The vibration frame 2 also includes a toggle block 22 ; a toggle block 22 is welded to the left and right sides of the vibration frame 2 .

[0038] In order to ensure the grinding effect of the bearing retainer and prevent the bearing retainer from being over-grinded, it is necessary to observe the grinding condition of the grinding bearing retainer during the grinding process; when observation is needed, the control cylinder 25 drives the baffle 1 6 and the hook 21 to descend, and descend until the hook 21 is aligned with the middle of the storage tube above the partition plate 7. When the storage tube moves to contact with the hook 21, the hook 21 will be inserted into the through hole of the net tube 8 to hook the storage tube. Then the control cylinder 25 drives the baffle 1 6, the hook 21 and the hooked storage tube to move upward and move out of the grinding medium, and make the storage tube located behind the toggle block 22. Most of the grinding media in the storage tube falls back into the vibration frame 2 from the through hole, and a small part of the grinding media remains between the vibration frame 2 and the shaft When the vibration frame 2 vibrates, it will drive the toggle block 22 to vibrate together. When the toggle block 22 vibrates, it will toggle the storage cylinder on the hook 21, causing the mounting column 3 to shake, so that the grinding medium remaining in the storage cylinder between the vibration frame 2 and the bearing holder is shaken off, and then the cylinder 2 5 is controlled to drive the baffle 1 6, the hook 21 and the hooked storage cylinder to move upward, so that the storage cylinder moves to the top of the vibration frame 2, so as to facilitate manual observation of the grinding condition of the bearing holder in the storage cylinder, and then the manual observation of the grinding condition of the bearing holder can be made through the through hole on the mesh tube 8, or the mounting column 2 4 can be directly unscrewed, and the bearing holder can be directly taken out for observation. After the observation, if grinding still needs to be continued, the storage cylinder can be put back into the vibration frame 2.

[0039] Example 3

[0040] On the basis of Example 2, Figure 3-Figure 4 As shown, it also includes a cylinder three 41 and a baffle two 42; two cylinder three 41 are fixedly connected to the front of the bottom plate 1; and the telescopic ends of all cylinder three 41 are fixedly connected to the baffle two 42.

[0041] In order to facilitate insertion into the grinding medium, the lower portion of the baffle plate 2 42 is configured to be conical.

[0042] A plurality of air pipes 43 are evenly spaced in the baffle plate 42, and the air jets of the air pipes 43 are arranged obliquely downward and rearward.

[0043] When the storage cylinder is placed in the vibration frame 2, due to the obstruction of the grinding medium, the storage cylinder cannot be directly placed near the partition plate 7, that is, the storage cylinder is exposed above the grinding medium, which makes it difficult for the subsequent grinding medium to bring the storage cylinder between the partition plate 7 and the lower side of the vibration frame 2, and then makes it difficult for the subsequent grinding medium to move the storage cylinder around the surface of the partition plate 7, and subsequently it is impossible to drive the net cylinder 8 and the grinding medium to relative displacement through the convex rod 10 on the partition plate 7 to enhance the grinding effect; therefore, when the storage cylinder is put back into the vibration frame 2, the cylinder three 41 is first controlled to drive the baffle two 42 to move downward, so that the baffle two 42 is inserted into the vibration frame 2. , so that baffle plate 2 42 is located in front of the partition plate 7, and the movement of the grinding medium on the front side is blocked by baffle plate 2 42, while the grinding medium on the rear side of baffle plate 2 42 continues to move backward and is stacked on the rear part of the vibration frame 2, so that the grinding medium on the upper side of the partition plate 7 close to the rear side of baffle plate 2 42 becomes less, and then the storage cylinder is put in, so that the storage cylinder is as close to the partition plate 7 as possible, so that the grinding medium can bring the storage cylinder between the partition plate 7 and the lower side of the vibration frame 2, and then the convex rod 10 on the partition plate 7 can drive the net cylinder 8 and the grinding medium to relative displacement and stagger, thereby enhancing the grinding effect; after being put in, the cylinder three 41 is controlled to drive the baffle plate 2 42 to move upward and reset.

[0044] In order to enhance the grinding effect, an abrasive containing a surfactant component is usually added to the grinding medium. A large amount of foam will be generated during the grinding process, resulting in foam attached to the bearing retainer after the storage cylinder is moved to the top of the vibration frame 2, which is not conducive to manual observation of the grinding situation. Therefore, an air pipe 43 is provided, and the air pipe 43 is pre-connected to an external air pump. After the storage cylinder is moved to the top of the vibration frame 2, the storage cylinder is located behind the air outlet of the air pipe 43, and then the air pump is controlled to start, so that high-pressure gas is sprayed to the bearing retainer in the storage cylinder through the air pipe 43 to spray off the residual foam on the bearing retainer, thereby facilitating manual observation of the grinding situation.

[0045] After the grinding medium has been used for a long time, it needs to be replaced. A collection box is placed at the lower rear of the vibration frame 2 in advance. At this time, the opening and closing part 201 is disassembled, so that the grinding medium in the vibration frame 2 will flow into the collection box for collection. Finally, some grinding medium will remain at the bottom of the vibration frame 2. At this time, since a partition plate 7 is provided in the vibration frame 2, part of the grinding medium below the partition plate 7 is not convenient for manual cleaning. The baffle plate 2 42 is driven downward by the control cylinder 3 41 so that the lower side of the baffle plate 2 42 is close to the bottom of the vibration frame 2, and then the air pump is controlled to start so that high-pressure gas is sprayed toward the bottom of the vibration frame 2 through the air pipe 43, so that the grinding medium remaining at the bottom of the vibration frame 2 is blown into the collection box for collection; then, the control cylinder 3 41 drives the baffle plate 2 42 to move up and reset, and the opening and closing part 201 is reinstalled back into the vibration frame 2, and finally new grinding medium is poured in to complete the replacement of the grinding medium.

[0046] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application.
