Description

Technical Field

[0001] This utility model relates to the field of ball screening technology, and in particular to a rapid ball screening device for bearings. Background Technology

[0002] Bearing balls are a key component of rolling bearings. They support the rotating shaft through rolling friction, while reducing friction and wear, and improving the efficiency and lifespan of mechanical equipment. Bearing balls are usually composed of an inner ring, an outer ring, balls, and a cage. Due to mechanical errors during production, bearing balls usually have a certain size error. Therefore, bearing balls are usually screened after production to ensure the quality of the bearing.

[0003] A search revealed that the document with publication number "CN213914805U" mentions "a bearing ball screening device, including a grading screening box, a sliding screening component, a sliding protective net, and a slide rail. The slide rail is located inside the grading screening box, the sliding screening component is located on the slide rail, and the sliding protective net is located on the sliding screening component. The sliding screening component includes a drive frame, a half gear, a drive motor, a screen frame, and an mounted screen disc. The drive frame is slidably located at the bottom of the slide rail, and the screen frame is slidably located on the slide rail." This device uses the horizontal reciprocating motion of the sliding screening component to grade and screen the balls. However, when screening the balls through the screen, some balls easily get stuck in the mesh due to their similar size. Shaking them is insufficient to dislodge these balls, leading to clogging and affecting the screening effect and speed of the bearing balls.

[0004] To address these issues, we provide a rapid ball bearing screening device. Utility Model Content

[0005] This application provides a rapid ball bearing screening device, which solves the problem that when existing screens screen balls, some balls are easily stuck in the screen mesh due to their similar size. It is difficult to shake the balls out of the screen mesh by shaking, which leads to screen clogging and affects the screening effect and speed of bearing balls.

[0006] This application provides a rapid screening device for bearing balls, including a device body and a screening mechanism, wherein the screening mechanism is arranged above the device body;

[0007] The screening mechanism includes a drive assembly mounted on top of the main body of the device, and a screening and unloading assembly is provided on the right side of the drive assembly.

[0008] Preferably, the drive assembly includes a support platform located at the top left side of the device body, a rotating mounting bracket rotatably connected to the top of the support platform, and a mounting ring fixedly connected to the top of the rotating mounting bracket.

[0009] Preferably, a drive motor is installed at the left end of the mounting ring frame, and a screening mounting column is provided at the right end of the mounting ring frame, with a screening roller connected to the right end of the screening mounting column via a slot.

[0010] Preferably, the screening and unloading assembly includes a screening inner cylinder installed inside the screening drum, the surface of the screening inner cylinder having a first screening hole, and the surface of the screening drum having a second screening hole, wherein the diameter of the first screening hole is larger than the diameter of the second screening hole.

[0011] Preferably, a sliding groove is provided on the right side of the screening inner cylinder, a sealing plate is movably connected to the right end of the screening inner cylinder, a connecting inner plate is provided on the inner side of the sealing plate, and a sealing outer plate is welded to the outer side of the sealing plate.

[0012] Preferably, a magnetic block is provided on the inner side of the groove, and the sealing plate is made of magnetically absorbable metal.

[0013] Preferably, a collection component is provided at the top of the main body of the device. The collection component includes a first collection groove fixedly installed at the top of the main body of the device, a second collection groove is provided to the right of the first collection groove, and a third collection groove is provided to the right of the second collection groove.

[0014] As can be seen from the above technical solution, this application provides a rapid screening device for bearing balls. The bearing balls to be screened are placed in the inner screening cylinder, and then a sealing plate is installed on the slide groove. This seals the inner screening cylinder and the screening drum with the sealing plate and the outer sealing plate, preventing the bearing balls from slipping off the sides during screening and ensuring the screening effect. Simultaneously, a magnetic block magnetically fixes the sealing plate, preventing it from sliding during screening and ensuring the stability of the sealing plate and the outer sealing plate. Then, a drive motor rotates the screening mounting column. This causes the screening drum to rotate, allowing the bearing balls to roll inside. Oversized bearing balls remain in the inner screening drum, while undersized balls are screened out through the second screening hole. Qualified bearing balls remain in the screening drum for rapid screening. Afterward, the sealing plate and outer sealing plate are opened, and the rotating mounting bracket on the support platform is rotated, causing the screening drum to tilt. This facilitates the unloading of the screened bearing balls. Simultaneously, multiple sets of collection tanks collect the bearing balls in groups during screening, improving the convenience of subsequent classification and use of the bearing balls.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The screening mechanism uses a sealing plate and an outer sealing plate to enclose the inner screening cylinder and screening drum, preventing the bearing balls from slipping off the sides during screening and ensuring effective screening. Magnetic blocks magnetically fix the sealing plate and outer sealing plate, ensuring their stability. A drive motor rotates the screening mounting column, causing the screening drum to rotate and the bearing balls to roll inside. During rotation, the bearing balls stuck in the screening holes automatically fall out under their own weight, preventing them from being stuck and affecting the screening of other bearing balls. By setting the diameter of the first screening hole to the maximum and minimum tolerance of the bearing balls, oversized bearing balls remain in the inner screening cylinder, while undersized balls are screened out through the second screening hole, leaving qualified bearing balls in the screening drum for rapid screening.

[0017] 2. By setting up the collection components, the sealing plate and the outer sealing plate are opened after screening. The rotating mounting frame is rotated on the support platform, which drives the screening roller to tilt, making it easier to unload the screened bearing balls. At the same time, multiple sets of collection tanks are used to collect the bearing balls in groups during screening, which improves the convenience of subsequent classification and use of bearing balls.

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] See Figure 1-4 A rapid screening device for bearing balls includes a main body 1 and a screening mechanism 2, with the screening mechanism 2 arranged above the main body 1.

[0026] The screening mechanism 2 includes a drive assembly 21 installed above the main body 1 of the device, and a screening and unloading assembly 22 is provided on the right side of the drive assembly 21.

[0027] In this utility model, the drive assembly 21 includes a support platform 211 located at the top left side of the main body 1. A rotating mounting frame 212 is rotatably connected to the top of the support platform 211, and a mounting ring frame 213 is fixedly connected to the top of the rotating mounting frame 212. The rotating mounting frame 212 rotates on the support platform 211, causing the screening roller 216 to tilt, which facilitates the unloading of the screened bearing balls.

[0028] In this utility model, a drive motor 214 is installed on the left end of the mounting ring 213, and a screening mounting column 215 is provided on the right end of the mounting ring 213. A screening roller 216 is connected to the right end of the screening mounting column 215 by a slot. The drive motor 214 drives the screening mounting column 215 to rotate, thereby causing the screening roller 216 to rotate, which facilitates the rapid screening of the bearing balls.

[0029] In this invention, the screening and unloading assembly 22 includes a screening inner cylinder 221 installed inside the screening drum 216. The surface of the screening inner cylinder 221 is provided with a first screening hole 222, and the surface of the screening drum 216 is provided with a second screening hole 223. The diameter of the first screening hole 222 is larger than the diameter of the second screening hole 223. The diameter of the first screening hole 222 is set to the maximum error of the bearing ball, and the diameter of the first screening hole 223 is set to the minimum error of the bearing ball. In this way, when screening the bearing balls, the excessively large bearing balls are left in the screening inner cylinder 221, while the excessively small ones are screened out through the second screening hole 223, and the qualified bearing balls are left in the screening drum 216, so as to quickly screen the bearing balls.

[0030] In this invention, a sliding groove 224 is provided on the right side of the screening inner cylinder 221, and a sealing plate 225 is movably connected to the right end of the screening inner cylinder 221. A connecting inner plate 226 is provided on the inner side of the sealing plate 225, and a sealing outer plate 227 is welded to the outer side of the sealing plate 225. The sealing plate 225 is installed on the sliding groove 224, thereby sealing the screening inner cylinder 221 and the screening roller 216 through the sealing plate 225 and the sealing outer plate 227, preventing the bearing balls from slipping off from both sides during screening, and ensuring the screening effect of the bearing balls.

[0031] In this utility model, a magnetic block 228 is provided on the inner side of the slide 224, and the sealing plate 225 is made of magnetically attractive metal. The magnetic block 228 is used to magnetically fix the sealing plate 225 to prevent the sealing plate 225 from sliding during screening, thus ensuring the stability of the installation of the sealing plate 225 and the outer sealing plate 227.

[0032] In some embodiments, a collection component 3 is provided at the top of the device body 1. The collection component 3 includes a first collection groove 31 fixedly installed at the top of the device body 1, a second collection groove 32 is provided on the right side of the first collection groove 31, and a third collection groove 33 is provided on the right side of the second collection groove 32. By using multiple collection grooves, the bearing balls are collected in groups during the screening process, thereby improving the convenience of subsequent classification and use of the bearing balls.

[0033] As can be seen from the above technical solution, in use, the device is installed at the desired location, and then the bearing balls to be screened are placed in the inner screening cylinder 221. Next, the sealing plate 225 is installed on the slide groove 224, thereby sealing the inner screening cylinder 221 and the screening drum 216 through the sealing plate 225 and the outer sealing plate 227, preventing the bearing balls from slipping off the sides during screening and ensuring the screening effect. Simultaneously, the sealing plate 225 is magnetically fixed by the magnetic block 228 to prevent slippage during screening, ensuring the stability of the installation of the sealing plate 225 and the outer sealing plate 227. Then, the drive motor 214 drives the screening mounting column 215 to rotate, thereby... The screening drum 216 rotates, causing the bearing balls to roll inside. Oversized bearing balls are left in the inner screening cylinder 221, while undersized balls are screened out through the second screening hole 223. Qualified bearing balls remain in the screening drum 216, thus quickly screening the bearing balls. Afterward, the sealing plate 225 and the outer sealing plate 227 are opened, and the rotating mounting bracket 212 rotates on the support platform 211, causing the screening drum 216 to tilt, facilitating the unloading of the screened bearing balls. Simultaneously, multiple sets of collection troughs collect the bearing balls in groups during screening, improving the convenience of subsequent classification and use. This completes the use of a rapid bearing ball screening device.
