Description

Technical Field

[0001] The present invention relates to the technical field of bearing production, and more particularly to a bearing ball assembly mechanism and an assembly line. Background Art

[0002] The bearing consists of four parts: inner ring, outer ring, roller and cage. The rollers are assembled either manually or automatically by machine. However, due to machining accuracy issues, there will be slight differences in the sizes of different inner rings, outer rings and rollers. To further improve assembly accuracy, the roller diameters must be measured and then assembled one by one. Existing machine assembly has the following shortcomings: 1. The roller diameters cannot be measured sequentially, resulting in the rollers not being able to better adapt to the inner and outer rings, and the assembly accuracy is low; 2. The length of the existing cylindrical cavity is fixed, and only a specified number of rollers can be assembled. The number of rollers that can be loaded at a time cannot be changed, resulting in low adaptability (if the assembly machine switches from 5 rollers to 7 rollers, manual disassembly and debugging of the equipment is required).

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] This application provides bearing ball assembly mechanism and assembly line, please refer to Figure 1-Figure 7 : It includes a base 1, a column 2, a measuring instrument 3 and a roller 4, and also includes; The limiting assembly 5 is used to limit the falling of the roller 4. The measuring instrument 3 is installed on the limiting assembly 5 and measures the outer diameter of the roller 4. The connecting assembly 6 can reciprocate in the horizontal X-axis and Y-axis directions. After being connected to the limiting assembly 5, the roller 4 moves from the limiting assembly 5 to the connecting assembly 6. The connecting assembly 6 includes a cylindrical cavity 7 and a blocking component 8. The blocking component 8 can divide the cylindrical cavity 7 into multiple virtual sub-cavities 9. The virtual sub-cavity 9 can only accommodate one roller 4. The blocking component 8 controls the rollers 4 to fill the virtual sub-cavities 9 from top to bottom in sequence. The blocking component 8 can control the number of rollers 4 in the cylindrical cavity 7.

[0018] Specifically in practical applications, the measuring instrument 3 in this mechanism can be an electronic micrometer or a laser caliper or a measuring instrument modified using the principles thereof. The limit assembly 5 can limit the roller 4 to prevent the roller 4 from falling uncontrollably. The limit assembly 5 is provided with a plurality of channels for the roller 4 to fall. The roller 4 can measure the diameter through the measuring instrument 3 before falling. Since the diameter of the roller 4 has an error, the system marks the position of the roller 4 after the measurement. The connecting assembly 6 can reciprocate in the horizontal X-axis direction and the Y-axis direction according to the position. After the limit assembly 5 is connected to the connecting assembly 6, the roller 4 moves from the limit assembly 5 to the connecting assembly 6. After the connecting assembly 6 moves multiple positions, the roller 4 required for a bearing can be removed (if 5 rollers 4 are required, it will move 5 positions). Then the blocking component 8 is controlled to release the roller 4, and finally the purpose of releasing the roller 4 is achieved. The logic of the connecting component 6 for selecting the roller 4 is: according to the sizes of the inner and outer rings of the bearing, the optimal average size of the roller 4 is calculated. If the optimal average size of the roller 4 is 1, the roller 4 with the average size closest to 1 is selected through calculation.

[0019] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The connecting assembly 6 also includes a slide rail 61 installed on the column 2, a slider 62 is installed on the slide rail 61, a threaded hole 63 is provided on the slider 62, a driving motor 64 is installed on the column 2, and a threaded shaft 65 is provided at the rotating end of the driving motor 64 for transmission connection with the threaded hole 63; an L-shaped plate 66 is installed above the slider 62, a linear cylinder 67 is installed at one end of the L-shaped plate 66, a connecting rod 68 is installed at the telescopic end of the linear cylinder 67, a cylinder 69 is provided at one end of the connecting rod 68, and the cylindrical cavity 7 is vertically arranged in the cylinder 69, and both ends of the cylindrical cavity 7 are in an open state; a partition 621 is installed on the side wall of the slider 62, and a hole 622 is provided on the partition 621.

[0020] Specifically in actual applications, controlling the rotation of the drive motor 64 can drive the slider 62 to move along the slide rail 61, that is, to move in the X-axis direction. This movement method can drive the cylindrical cavity 7 to move to the position corresponding to the specified target roller 4. Then, the linear cylinder 67 is controlled to extend, and the linear cylinder 67 drives the cylinder 69 and the cylindrical cavity 7 to move, that is, to move in the Y-axis direction. The cylindrical cavity 7 is aligned with the target roller 4, and the roller 4 can enter the cylindrical cavity 7. The cylinder 69 and the hole 1 622 are in a misaligned state.

[0021] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Example 1 of the blocking component 8, the blocking component 8 includes an annular groove 811 provided on the inner wall of the cylindrical cavity 7, and there are multiple annular grooves 811. An airbag 812 is installed on the annular groove 811. The volume of the airbag 812 increases when it is inflated to block the roller 4 from falling, and the volume of the airbag 812 decreases when it is exhausted to release the roller 4 from falling. A gas distribution valve 813 is provided on one side of the partition 621. The gas distribution valve 813 can independently control the inflation and exhaust of the airbag 812. Multiple gas distribution valves 813 can be set, and the distance between the airbags 812 is the same as the diameter of the roller 4.

[0022] Specifically, in practical applications, the working method of the first embodiment of the barrier component 8 is described as follows. If the batch of bearings requires five rollers 4, by calculating the gap between the inner ring and the outer ring of the bearing, it is found that the average diameter of the five rollers 4 should be 1 cm. The diameter of the roller 4 at the bottom of the limit assembly 5 can be determined by measuring with the measuring instrument 3. After calculation, the five rollers 4 with an average diameter closest to 1 are obtained. Then, the drive motor 64 and the linear cylinder 67 are controlled to move in coordination, and the five rollers 4 with an average value closest to 1 are sequentially received into the cylindrical cavity 7. refer to Figure 4 and Figure 5 The airbags 8 are arranged from top to bottom in the order of No. 1 to No. 7. When the first roller 4 is accommodated, the No. 1 airbag 8 is expanded and the other airbags 8 are contracted. When the second roller 4 is accommodated, the No. 2 airbag 8 is expanded and the other airbags 8 are contracted. This process is repeated until the fifth roller 4 is accommodated. This method can achieve the purpose of taking out the rollers 4 in the limiting assembly 5 one by one. Finally, the linear cylinder 67 is controlled to shorten, the cylindrical cavity 7 is aligned with the hole 1 622, the No. 5 airbag is contracted, and the roller 4 in the cylindrical cavity 7 is released.

[0023] According to actual needs, the number of airbags 8 can be set to more; The gas distribution valve 813 can accurately control the inflation and deflation of the airbag 8.

[0024] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 , Example 2 of the blocking component 8, the blocking component 8 includes a long hole 821 opened on the side wall of the cylinder 69, the setting of the long hole 821 will not interfere with the moving path of the roller 4, a telescopic cylinder 822 is installed on the connecting rod 68, and a blocking rod 823 is installed at the telescopic end of the telescopic cylinder 822, the blocking rod 823 is hinged to the telescopic cylinder 822, and a torsion spring 824 is installed between the blocking rod 823 and the telescopic cylinder 822, and a limit block 825 is installed at the telescopic end of the telescopic cylinder 822. The torsion spring 824 makes the blocking rod 823 close to the limit block 825, and the elastic force generated by the torsion spring 824 can support multiple rollers 4, and an interference rod 826 is installed on the partition 621. The lower end of the blocking rod 823 contacts the interference rod 826, and the blocking rod 823 rotates clockwise, and the blocking rod 823 leaves the position of the cylindrical cavity 7 to release the roller 4 to fall.

[0025] Specifically, in practical applications, the working method of the second embodiment of the barrier component 8 is described as follows. If the batch of bearings requires five rollers 4, by calculating the gap between the inner ring and the outer ring of the bearing, it is found that the average diameter of the five rollers 4 should be 1.01 cm. The diameter of the roller 4 at the bottom end of the limit assembly 5 can be determined by measuring with the measuring instrument 3. After calculation, the five rollers 4 with an average roller diameter closest to 1.01 cm are obtained. Then, the drive motor 64 and the linear cylinder 67 are controlled to move in coordination, and the five rollers 4 with an average value closest to 1 are sequentially received into the cylindrical cavity 7. Since the mechanism matches the rollers 4 in an optimal solution, the rollers 4 can be assembled normally even when the average diameter of the five rollers 4 is less than 1.01 cm.

[0026] refer to Figure 4 and Figure 5 The telescopic cylinder 822 extends from top to bottom by a distance of 1 cm to 7 cm (the distance is close to the diameter of the roller 4). When the first roller 4 is accommodated, the telescopic cylinder 822 extends by 1 cm; when the second roller 4 is accommodated, the telescopic cylinder 822 extends by 2 cm, and so on until the fifth roller 4 is accommodated. This method can achieve the purpose of removing the rollers 4 in the limit assembly 5 one by one; (As a counterexample, if the extension is directly 2 cm, the limit assembly 5 will be pushed away and will not restrict the fall of the rollers 4. The two adjacent rollers 4 will directly enter the cylindrical cavity 7, which contains the roller 4 that has not been measured, affecting the assembly accuracy). like Figure 2As shown, the linear cylinder 67 is finally controlled to shorten, the cylindrical cavity 7 moves, and the cylindrical cavity 7 is aligned with the hole 1 622 in the vertical direction. The telescopic cylinder 822 is directly extended to the longest state. At this time, the blocking rod 823 contacts the interference rod 826, forcing the blocking rod 823 to rotate, so that the blocking rod 823 rotates out of the range of the cylindrical cavity 7. The roller 4 can be directly moved downward, and finally the assembly is completed; When the linear cylinder 67 is shortened and reset, the blocking rod 823 can be reset by the action of the torsion spring 824 and be in a horizontal state again.

[0027] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The limiting assembly 5 includes a support plate 51 installed on the column 2, an L-shaped connecting plate 52 is installed at one end of the upper surface of the support plate 51, and a rectangular bar 53 is installed on one side of the L-shaped connecting plate 52. A second hole 54 is opened on the rectangular bar 53, and there are multiple holes 54. The axis of the second hole 54 is in a vertical state, and the axis of the second hole 54 and the axis of the first hole 622 are in a staggered state; a horizontal hole 55 is opened at the lower end of the L-shaped connecting plate 52, and a piston rod 56 is provided in the horizontal hole 55. A blocking block 511 is installed on the support plate 51, and one end of the piston rod 56 passes through the blocking block 511. A rectangular block 512 is installed on the piston rod 56, and a compression spring 513 is installed between the rectangular block 512 and the blocking block 511.

[0028] Specifically, in actual application, the compression spring 513 drives the piston rod 56 and the rectangular block 512 to move toward the horizontal hole 55. The blocking block 511 makes the movement of the piston rod 56 more stable. At this time, the end of the piston rod 56 away from the compression spring 513 blocks the second hole 54. The roller 4 in the second hole 54 cannot fall due to the obstruction of the piston rod 56. However, when the cylindrical cavity 7 in the connecting assembly 6 moves, the piston rod 56 can be pushed open, and the second hole 54 can be aligned with the cylindrical cavity 7 for the roller 4 to pass through.

[0029] Reference Figure 1 、 Figure 2 and Figure 3 , it also includes a circular plate 21 installed at the upper end of the column 2, a storage box 22 is installed on the circular plate 21, and there are multiple storage boxes 22. A discharge pipe 23 is installed at the lower end of the storage box 22, a linear motor 24 is installed at the center of the circular plate 21, and a circular plate 25 is installed at the telescopic end of the linear motor 24.

A connecting hose 27 is installed between the material guide pipe 26 and the second hole 54.

[0030] Specifically in actual application, the roller 4 is located in the storage box 22, and the linear motor 24 can indirectly drive the guide tube 26 to move up and down through the extension and contraction of the linear motor 24. The guide tube 26 and the discharge tube 23 are in a slidable connection state. The guide tube 26 can be inserted into the bottom of the storage box 22, so that the roller 4 can move smoothly from the storage box 22 to the connecting hose 1 27 and the hole 2 54.
