Description

Technical Field

[0001] This utility model relates to the field of bearing steel ball screening technology, and in particular to a defective product collection device for screening bearing steel ball small balls. Background Technology

[0002] Bearing balls are rolling elements used in bearings, usually made of high-strength, wear-resistant steel. Their main function is to reduce friction and improve the efficiency of rotating parts. Inevitably, defective bearing balls will be produced during production. Defective balls may have problems such as incorrect size, irregular shape, or surface defects, which can lead to increased friction or uneven movement, thereby reducing the overall efficiency of the bearing. Therefore, it is necessary to screen out defective balls.

[0003] Traditionally, bearing steel balls are screened using a vibrating screener. After screening, a collection device is needed to collect the defective balls. However, most existing vibrating screeners lack a limiting mechanism for the collection device. When the vibrating screener is working, the collection device also vibrates, which may cause the position of the collection device to shift. This results in some defective bearing steel balls failing to fall into the collection device, causing them to scatter and become difficult to collect. Therefore, it is necessary to design a defective ball collection device for screening bearing steel balls to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a defective product collection device for screening bearing steel balls.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A defective ball collection device for screening bearing steel balls includes a base plate, a vibrating screener mounted on top of the base plate, a support plate mounted on top of the base plate, a collection box mounted on top of the support plate, four square-shaped casters fixedly connected to the bottom of the support plate, side plates fixedly connected to both sides of the collection box, two positioning rods passing through the side plates, holes adapted to the positioning rods being opened on the side plates, and the four positioning rods fixedly connected to the top of the support plate. A fixing plate is fixedly connected to the top of one end of the base plate, and limit plates are fixedly connected to the top of both ends of the fixing plate. The bottom end of the limit plate is inclined. Two first guide rods are fixedly connected to the top of the end of the base plate away from the fixing plate, and a first sliding plate is sleeved on each of the two first guide rods. The first sliding plate slidably connects to the first guide rods. A U-shaped plate is fixedly connected to the two first sliding plates on their adjacent sides, and a spring is mounted on the top of the first sliding plate, which is sleeved on the first guide rod. The device utilizes the coordinated use of positioning rods, side plates, and limit plates. The technical means of restricting the position of the collection box and the position of the tray by the U-shaped plate, through the cooperation of the positioning rod, side plate, and limiting plate, can restrict the lateral and vertical position of the side plate, thus restricting the position of the collection box. The U-shaped plate blocks one side of the tray, so that the collection box can be stably positioned directly below the discharge port of the vibrating screen. When the vibrating screen is working, the position of the collection box will not shift. This effectively solves the problem mentioned in the background technology that most existing vibrating screens lack a limiting mechanism for the collection device. When the vibrating screen is working, the collection device will also vibrate, and its position may shift, causing some of the falling defective bearing steel balls to fail to fall into the collection device, resulting in the bearing steel balls being scattered everywhere and difficult to collect. Thus, it achieves the technical effect of effectively constraining the position of the collection box, ensuring its stability during the vibrating screening process, avoiding the inability to effectively collect bearing steel balls due to positional shift. It is simple to operate and easy to install and remove the collection box.

[0007] As a further embodiment of this utility model, a roller is rotatably connected to the U-shaped plate, a pressing plate is provided at the bottom of the roller, and a pull rod is fixedly connected to one side of the pressing plate.

[0008] As a further embodiment of this utility model, the bottom of the tray is fixedly connected to two second sliding plates, and a second guide rod is provided inside the second sliding plate, with the second sliding plate slidably connected to the second guide rod.

[0009] As a further embodiment of this utility model, the second guide rod is fixedly connected to the fixing plate.

[0010] As a further embodiment of this utility model, a third sliding plate is fixedly connected to both sides of the extrusion plate, a third guide rod is passed through the third sliding plate, the third sliding plate is slidably connected to the third guide rod, and a square plate is fixedly connected to both sides of the third guide rod.

[0011] As a further embodiment of this utility model, both square plates are fixedly connected to the top of the base plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing a combination of positioning rods, side plates, and limiting plates to restrict the position of the collection box, and a U-shaped plate to restrict the position of the pallet, the positioning rods, side plates, and limiting plates can restrict the lateral and vertical positions of the side plates, thus limiting the position of the collection box. The U-shaped plate, positioned on one side of the pallet, ensures the collection box is stably located directly below the discharge port of the vibrating screen. This prevents the collection box from shifting during operation, effectively solving the problem mentioned in the background section where most existing vibrating screens lack a limiting mechanism for the collection device. During operation, the collection device vibrates, potentially causing it to shift, resulting in some defective bearing balls failing to fall into the collection device and scattering, making collection difficult. This solution effectively constrains the position of the collection box, ensuring its stability during vibrating screening and preventing ineffective collection of bearing balls due to positional shift. The system is also simple to operate, facilitating installation and removal of the collection box. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1 - Figure 6A defective ball screening and collection device for bearing steel balls includes a base plate 1, a vibrating screener 2 mounted on top of the base plate 1, a support plate 3 mounted on top of the base plate 1, a collection box 4 mounted on top of the support plate 3, four square-shaped casters 5 fixedly connected to the bottom of the support plate 3, side plates 7 fixedly connected to both sides of the collection box 4, two positioning rods 6 passing through the side plates 7, and holes adapted to the positioning rods 6 on the side plates 7, all four positioning rods 6 fixedly connected to the top of the support plate 3, and a fixing plate 14 fixedly connected to the top of one end of the base plate 1, with limit plates 8 fixedly connected to the top of both ends of the fixing plate 14. The bottom end of the limiting plate 8 is sloped. Two first guide rods 9 are fixedly connected to the top of the bottom plate 1 at the end furthest from the fixed plate 14. Each of the two first guide rods 9 is fitted with a first sliding plate 10. The first sliding plate 10 is slidably connected to the first guide rod 9. When the first sliding plate 10 moves, it moves along the first guide rod 9, ensuring the stability of the U-shaped plate 11 during vertical movement. The two first sliding plates 10 are fixedly connected to the U-shaped plate 11 on their adjacent sides. A spring 13 is provided at the top of the first sliding plate 10, and the spring 13 is fitted onto the first guide rod 9. By providing the spring 13, the spring 13 returns to its natural state. When the U-shaped plate 11 descends and no longer blocks one side of the pallet 3, the pallet 3 can be pulled out. Due to the use of positioning rods, side plates, and limiting plates working together to restrict the position of the collection box, and the U-shaped plate restricting the position of the pallet, the positioning rods, side plates, and limiting plates can restrict the lateral and vertical positions of the side plates, thus restricting the position of the collection box. With the U-shaped plate blocking one side of the pallet, the collection box can be stably positioned directly below the discharge port of the vibrating screen. During operation of the vibrating screen, the position of the collection box will not shift, effectively solving the problem of… The prior art, as described in the background section, largely lacks a mechanism to limit the position of the collection device on vibrating screens. During operation, the collection device vibrates, potentially causing it to shift position. This results in some defective bearing balls failing to fall into the collection device, scattering and becoming difficult to collect. The proposed solution effectively constrains the position of the collection box, ensuring its stability during vibrating screening and preventing ineffective collection of bearing balls due to positional shifts. It also offers the advantages of simple operation and easy installation and removal of the collection box.

[0024] In this embodiment, a roller 12 is rotatably connected to the U-shaped plate 11, and a pressing plate 17 is provided at the bottom of the roller 12. A pull rod 18 is fixedly connected to one side of the pressing plate 17.

[0025] In this embodiment, two second sliding plates 16 are fixedly connected to the bottom of the tray 3. A second guide rod 15 is provided inside the second sliding plate 16. The second sliding plate 16 is slidably connected to the second guide rod 15. When the tray 3 moves, it will drive the second sliding plate 16 to move along the second guide rod 15 to ensure the stability of the tray 3 when it moves.

[0026] In this embodiment, the second guide rod 15 is fixedly connected to the fixing plate 14.

[0027] In this embodiment, a third sliding plate 19 is fixedly connected to both sides of the extrusion plate 17. A third guide rod 20 is provided on the third sliding plate 19. The third sliding plate 19 is slidably connected to the third guide rod 20. A square plate 21 is fixedly connected to both sides of the third guide rod 20. When the extrusion plate 17 moves, it will drive the third sliding plate 19 to move along the third guide rod 20, ensuring the stability of the extrusion plate 17 when it moves.

[0028] In this embodiment, the tops of both square plates 21 are fixedly connected.

[0029] Working Principle: When using this device, place the bearing steel balls into the vibrating screen 2, connect an external power supply, and start the vibrating motor of the vibrating screen 2 to vibrate the screening box for screening. Defective products will fall through the screen into the collection box 4 and be collected, while qualified products will remain in the screening box of the vibrating screen 2. To remove the collection box 4, pull the lever 18. The lever 18 will move the squeezing plate 17, which will move the bottom of the roller 12. At this time, the contracted spring 13 will extend, allowing the first sliding plate 10 to descend. The first sliding plate 10 will then move the U-shaped plate 11, which will then descend. The U-shaped plate 11 will no longer block one side of the support plate 3, allowing the support plate 3 to be pulled out. Remove the side plate 7 from the positioning rod 6 to remove the collection box 4. When installing the collection box 4, place the side plate 7 on the positioning rod 6 for positioning. Push the tray 3 to move it, and move the side plate 7 to the bottom of the limiting plate 8. The lateral position of the collection box 4 can be limited by the cooperation of the positioning rod 6 and the side plate 7. The vertical position of the collection box 4 can be limited by the cooperation of the side plate 7 and the limiting plate 8. After the tray 3 moves past the U-shaped plate 11, push the pull rod 18 to make the squeezing plate 17 squeeze the roller 12. The squeezing plate 17 will squeeze the roller 12 and make the roller 12 rise. The roller 12 will drive the U-shaped plate 11 to rise. The first sliding plate 10 will squeeze the spring 13 again and make the spring 13 contract. When the roller 12 is at the top of the squeezing plate 17, the U-shaped plate 11 will block one side of the tray 3, which can limit the position of the tray 3 and make the tray 3 between the U-shaped plate 11 and the fixed plate 14. The collection box 4 can be installed in place to prevent the position of the collection box 4 from shifting during the screening process, which would cause some defective bearing steel balls to scatter everywhere.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
