Description

Technical Field

[0001] The utility model relates to the technical field of bearing steel ball sorting equipment, in particular to a motor bearing steel ball sorting machine. Background Art

[0002] Motor bearing steel balls are used to reduce friction and support mechanical rotational loads, primarily in precision rolling bearings and other machinery. They significantly reduce friction during equipment operation, improving efficiency and stability. They are widely used in numerous industrial sectors, including automotive, home appliances, and medical devices. With the continued advancement of global industrialization, demand for motors and bearings continues to grow. Driven particularly by emerging markets such as new energy vehicles, demand for bearing steel balls, a core component, is expected to continue to rise.

[0003] In the existing technology, some used and discarded steel balls become uneven in size due to long-term operation and wear. Some have reduced diameters, while others have irregular deformation or damage due to friction. Steel balls of different diameters are mixed together during use, which brings additional difficulties to their sorting and reuse. Due to this mixed state and the existence of steel balls of similar sizes, traditional manual sorting becomes cumbersome and inefficient. Workers usually need to rely on the naked eye to identify and distinguish these tiny differences, making it difficult to ensure the accuracy and consistency of sorting. Even experienced workers find it difficult to complete the sorting task perfectly, especially when dealing with tens of thousands of steel balls. The work results are often unsatisfactory. In addition, if substandard steel balls are mistakenly used for bearing manufacturing during manual sorting, it will cause increased noise and vibration during machine operation, and even cause serious mechanical failures. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a motor bearing steel ball sorting machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a motor bearing steel ball sorting machine, comprising a workbench, a base is fixed on the top of the workbench, the inner wall of the base is rotatably connected to a rotating spindle, round-headed rotary vanes are fixed to the circumferences of both ends of the rotating spindle, a placement frame is fixed on the top of the round-headed rotary vane, an end moment mounting plate is fixed to one end of the placement frame, a sorting panel is provided on one side of the end moment mounting plate, a matrix of embedded holes is opened on one side of the sorting panel, an end extension plate is fixed on the other end of the placement frame, an end extension plate is rotatably connected to an end side shaft on one side, a threaded frame is fixed on one end of the end side shaft, a threaded frame is threadedly connected to a threaded rod on the inner wall of the threaded frame, a vertical bevel gear is fixed on the bottom of the threaded rod, and multiple rotating discs are fixed on the top of the workbench. The bottom piece has a right auxiliary shaft fixed on one side of the rotating bottom piece, and the circumference of the right auxiliary shaft is rotatably connected to a vertical shaft piece, and the top of the vertical shaft piece is rotatably connected to the bottom of the vertical bevel gear. A hollow shaft is fixed on one side of the rotating bottom piece on the other side, and one end of the hollow shaft is rotatably connected to a parallel bevel gear, and one end of the parallel bevel gear is rotatably connected to one end of the right auxiliary shaft. An output end shaft is fixed on the other end of the parallel bevel gear, and the circumference of the output end shaft is rotatably connected to the inner wall of the hollow shaft. The output end shaft is driven by an output motor. In the prior art, some used and discarded steel balls will become uneven in size due to long-term operation and wear. Some have reduced diameters, and some have irregular deformation or damage due to friction. Steel balls of different diameters will be used differently. In the process of sorting, they will be mixed together, which brings additional difficulty to their sorting and reuse. Due to this mixed state and the existence of steel balls of similar sizes, traditional manual sorting work becomes cumbersome and inefficient. Workers usually need to rely on the naked eye to identify and distinguish these tiny differences, and it is difficult to ensure the accuracy and consistency of sorting. Even experienced workers find it difficult to complete the sorting task perfectly, especially when dealing with tens of thousands of steel balls. The work effect is often unsatisfactory. In addition, if substandard steel balls are mistakenly used for bearing manufacturing during manual sorting, it will cause increased noise and vibration during machine operation, and even cause serious mechanical failure. In response to such problems, the utility model adopts the method of installing a placement frame to solve The solution is to realize that when the staff needs to separate steel balls of a certain diameter, they can install a sorting panel of the diameter to the end moment mounting plate, and then put the steel balls to be sorted into the placement frame, start the motor to make the output end shaft drive the parallel bevel gear to rotate, and the engagement makes the vertical bevel gear rotate. At the same time, the threaded rod screws out of the threaded frame downward, causing the placement frame to rotate counterclockwise. A large number of steel balls reach the sorting panel with the rotation, and at the same time, suitable steel balls are embedded in the embedding holes. The staff can use vibration equipment to accelerate this step, and then the motor is reversed to make the threaded rod screw into the threaded frame upward, causing the placement frame to rotate clockwise. A large number of steel balls fall back with the rotation, and suitable steel balls are embedded in the embedding holes. The staff can remove the sorting panel and collect the steel balls, thereby improving production efficiency.

[0006] Preferably, a trapezoidal groove is provided on one side of the end moment mounting plate, a square groove is provided on the inner wall of the trapezoidal groove, a spring plate is fixed on the inner wall of the square groove, an embedded bead is fixed in the middle of the spring plate, a trapezoidal piece is fixed on the bottom of the sorting panel, and a spherical groove is provided on the bottom of the trapezoidal piece. In the prior art, the collection and sorting of steel balls require the removal of the end moment mounting plate to collect the steel balls and then reassemble them for the next round of sorting. This repetitive disassembly and assembly is not only time-consuming and labor-intensive, but also has a negative impact on work efficiency. The end moment mounting plate is closely combined with the sorting panel, and the sorting panel has embedded holes of different diameters for sorting steel balls of different diameters. According to the sorting requirements, the staff must replace the sorting panels with embedded holes of different diameters to achieve accurate classification. Each time the sorting panel is replaced, the end moment mounting plate needs to be disassembled and reinstalled The process of installing the plate increases the complexity of the operation. If bolts and other fixing parts are used, the end torque mounting plate is often difficult to remove, especially after frequent operations. The bolts will be stuck or the threads will be worn due to long-term stress, making disassembly extremely difficult. This not only reduces work efficiency, but also increases work difficulty and causes delays in the production process. To address this problem, the utility model solves it by installing trapezoidal parts, so that when the staff finishes collecting, they pull out and remove the end torque mounting plate. When continuing to sort, the original end torque mounting plate or the trapezoidal part of the end torque mounting plate of a different model is slid into the trapezoidal groove. When the trapezoidal part slides to the lowest end, the spring plate rebounds to embed the embedded bead into its spherical groove, thereby stopping the end torque mounting plate and fixing it, while giving the staff force feedback, so as to achieve the effect of improving work efficiency.

[0007] Preferably, a small bottom hole is provided at the bottom of the inner wall of the embedded hole, and an exclusion groove is provided on one side of the end moment mounting plate. In the prior art, in the process of steel ball sorting, it is crucial to ensure that each steel ball can be accurately classified into the sieve plate of the corresponding diameter. However, the existing sorting method usually requires staff to start sorting from the steel balls with the smallest diameter. The reason for adopting this order is that the steel balls with small diameters can enter the holes of the sieve plate with large diameters. If the steel balls with large diameters are sorted first, the steel balls with small diameters will be mixed in, resulting in poor sorting effect. Although this sorting method guarantees the accuracy of screening to a certain extent, it also brings many operational challenges. First, the staff needs to make a preliminary diameter judgment on the steel balls and select them. Selecting the steel balls with the smallest diameter for sorting increases the complexity of the work. Secondly, once there are many types of steel balls, this sorting order will make the work process lengthy and inefficient. In addition, the principle of sorting small-diameter steel balls first also increases the steps of the operation, because after completing a round of sorting, the staff needs to re-sort the remaining steel balls and sort them again. To solve this problem, the utility model adopts the method of opening a bottom hole to solve it, so that the diameter of the bottom hole can be only smaller than the embedded hole, so that in the screening process, after the steel balls with smaller diameter enter the embedded hole, they will fall from the bottom hole and re-enter the placement frame from the exclusion slot, so that the staff can select steel balls of any diameter for sorting, thereby improving work efficiency.

[0008] Preferably, a blocking plate is fixed on the top of the workbench to prevent the placing frame from rotating at too large an angle and exerting too much pressure on the threaded rod, causing it to bend and deform. The blocking plate provides supporting force, thereby increasing the service life of the equipment.

[0009] Preferably, a pad groove is provided on the top of the blocking plate to increase the contact area between the blocking plate and the placement frame, prevent scratches, and increase the service life of the equipment.

[0010] Preferably, a triangular fixing piece is fixed to the bottom end of the blocking plate to improve the stability of the blocking plate and the stability of the equipment.

[0011] Preferably, the four corners of the workbench are set as chamfers to reduce the weight of the equipment and increase the scope of application of the equipment.

[0012] Beneficial effects:

Some of the used and discarded steel balls are After long-term operation and wear, the size of the steel balls will become uneven. Some will have reduced diameters, while others will have irregular deformation or damage due to friction. Steel balls of different diameters will be mixed together during use, which brings additional difficulties to their sorting and reuse. Due to this mixed state and the existence of steel balls of similar sizes, traditional manual sorting becomes cumbersome and inefficient. Workers usually need to rely on the naked eye to identify and distinguish these tiny differences, making it difficult to ensure the accuracy and consistency of sorting. Even experienced workers find it difficult to complete the sorting task perfectly, especially when dealing with tens of thousands of steel balls. The work results are often unsatisfactory. In addition, if substandard steel balls are mistakenly used for bearing manufacturing during manual sorting, The problem of this problem is that the noise and vibration of the machine increase during operation, and even cause serious mechanical failure. The problem is solved by installing a placement frame 203. When the staff needs to separate steel balls of a certain diameter, they can install a sorting panel 205 of the diameter to the end moment mounting plate 204, and then put the steel balls to be sorted into the placement frame 203. The motor is started to make the output end shaft 2017 drive the parallel bevel gear 2016 to rotate, and the engagement makes the vertical bevel gear 2011 rotate. At the same time, the threaded rod 2010 screws out of the threaded frame 209 downward, causing the placement frame 203 to rotate counterclockwise. A large number of steel balls reach the sorting panel 205 with the rotation, and the appropriate steel balls are embedded in the embedding holes 206. The staff can use vibration equipment to accelerate this step, and then the motor is reversed.The threaded rod 2010 is screwed upward into the threaded frame 209, so that the placement frame 203 rotates clockwise.

A pad groove 501 is provided on the top of the blocking plate 5 to increase the contact area between the blocking plate 5 and the placement frame 203, prevent scratches, and increase the service life of the equipment. A triangular fixing piece 502 is fixed to the bottom end of the blocking plate 5 to improve the stability of the blocking plate 5 and the stability of the equipment. The four corners of the workbench 1 are set as cut corners 101 to reduce the weight of the equipment and increase the scope of application of the equipment.

[0029] A trapezoidal groove 3 is provided on one side of the end moment mounting plate 204, and a square groove is provided on the inner wall of the trapezoidal groove 3. A spring plate 301 is fixed on the inner wall of the square groove, and an embedded bead 302 is fixed in the middle of the spring plate 301. A trapezoidal piece 303 is fixed to the bottom of the sorting panel 205, and a spherical groove is provided at the bottom of the trapezoidal piece 303. The collection and sorting of the steel balls require the removal of the end moment mounting plate 204 to collect the steel balls and then reassemble them for the next round of sorting. This repetitive disassembly and assembly is not only time-consuming and labor-intensive, but also has a negative impact on work efficiency. The end moment mounting plate 204 is tightly combined with the sorting panel 205, and the sorting panel 205 has embedded holes 206 of different diameters for sorting steel balls of different diameters. According to the sorting requirements, the staff must replace the sorting panel 205 with embedded holes 206 of different diameters to achieve accurate sorting. Each time the sorting panel 205 is replaced, the end moment mounting plate 204 needs to be removed and reinstalled The installation plate 204, this process increases the complexity of the operation. If bolts and other fixing parts are used, the end torque mounting plate 204 is often difficult to remove, especially after frequent operations. The bolts will be stuck or the threads will be worn due to long-term stress, making disassembly extremely difficult. This not only reduces work efficiency, but also increases work difficulty and causes delays in the production process. The problem is solved by installing a trapezoidal piece 303. After the staff finishes collecting, they pull out and remove the end torque mounting plate 204. When continuing to sort, the original end torque mounting plate 204 or the trapezoidal piece 303 of a different model of end torque mounting plate 204 is slid into the trapezoidal groove 3. When the trapezoidal piece 303 slides to the lowest end, the spring plate 301 rebounds to embed the embedded bead 302 into its spherical groove, thereby stopping the end torque mounting plate 204 and fixing it, while giving the staff force feedback, thereby achieving the effect of improving work efficiency.A small bottom hole 4 is provided at the bottom of the inner wall of the embedded hole 206, and an exclusion groove 401 is provided on one side of the end moment mounting plate 204. In the process of steel ball sorting, it is crucial to ensure that each steel ball can be accurately classified into the sieve plate of the corresponding diameter. However, the existing sorting method usually requires staff to start sorting from the steel balls with the smallest diameter. The reason for adopting this order is that the steel balls with small diameters can enter the holes of the sieve plate with large diameters. If the steel balls with large diameters are sorted first, the steel balls with small diameters will be mixed in, resulting in poor sorting effect. Although this sorting method guarantees the accuracy of screening to a certain extent, it also brings many operational challenges. First, the staff needs to make a preliminary diameter judgment on the steel balls and select the ones with the smallest diameters. Small-diameter steel balls are sorted, which increases the complexity of the work. Secondly, once there are many types of steel balls, this sorting order will make the work process lengthy and inefficient. In addition, the principle of sorting small-diameter steel balls first also increases the steps of the operation, because after completing a round of sorting, the staff needs to re-sort the remaining steel balls and sort them again. The solution is to open a bottom hole 4, so that the diameter of the bottom hole 4 can be only smaller than the embedding hole 206. In the screening process, after the steel balls with smaller diameters enter the embedding hole 206, they will fall from the bottom hole 4 and re-enter the placement frame 203 from the exclusion slot 401, so that the staff can choose steel balls of any diameter for sorting, thereby improving work efficiency.

[0030] The working principle of the present utility model is as follows: when the staff needs to separate the steel balls of a certain diameter, they can install the sorting panel 205 of the diameter to the end moment mounting plate 204, and then put the steel balls to be sorted into the placement frame 203, start the motor to make the output end shaft 2017 drive the parallel bevel gear 2016 to rotate, meshing to make the vertical bevel gear 2011 rotate, and at the same time, the threaded rod 2010 screws out of the threaded frame 209 downward, so that the placement frame 203 rotates counterclockwise, and a large number of steel balls reach the sorting panel 205 with the rotation, and at the same time, the appropriate steel balls are embedded in the embedding holes 206. The staff can use a vibration device to accelerate this step, and then the motor is reversed to make the threaded rod 2010 screw into the threaded frame 209 upward, so that the placement frame 203 rotates clockwise, and a large number of steel balls are separated. The steel balls fall back with the rotation, and suitable steel balls are embedded in the embedding holes 206. The staff can remove the sorting panel 205 to collect the steel balls. When the staff has finished collecting, they pull out and remove the end moment mounting plate 204. When continuing to sort, the original end moment mounting plate 204 or the trapezoidal piece 303 of a different type of end moment mounting plate 204 is slid into the trapezoidal groove 3. When the trapezoidal piece 303 slides to the lowest end, the spring plate 301 rebounds to embed the embedded balls 302 into its spherical groove, thereby stopping the end moment mounting plate 204 and fixing it. During the screening process, steel balls with smaller diameters enter the embedding holes 206, fall from the bottom small holes 4, and re-enter the placement frame 203 from the exclusion slot 401, so that the staff can select steel balls of any diameter for sorting.
