Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing and manufacturing, in particular to a high-precision ball-gathering structure of a bearing. Background Art

[0002] During the installation of the bearing balls, the balls are randomly distributed inside the bearing. The balls can be separated and correctly installed in the bearing by separating and gathering the balls, so that the balls are gathered and positioned. The separation and gathering of the balls in the bearing is a key process step, which helps to correctly install the bearing and ensure the appropriate performance of the bearing under load. When performing this process, special tools or methods are usually used to separate and gather the balls to prevent damage to the balls or the internal structure of the bearing, so as to ensure the accuracy of the process and the reliability of the bearing.

[0003] However, the existing bearing ball gathering structure, such as the single-station ball gathering and dividing mechanism of a bearing with patent application number CN201821723658.5, can only drive a single ball dividing needle to perform ball gathering and dividing work through the ball dividing and gathering assembly. A single ball dividing needle needs to perform multiple ball gathering and dividing to ensure that the balls are installed in the correct position. In addition, different bearings have different numbers of balls inside. The number of ball dividing needles cannot be accurately matched with the number of balls, making it impossible for the ball dividing needle to divide the balls accurately, thereby affecting the efficiency of the ball dividing needle in dividing and gathering the bearing balls. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a high-precision ball-gathering structure for bearings, which can solve the problem that the existing ball-gathering structure for bearings can only drive a single ball-gathering needle to perform ball-gathering work through a ball-gathering and ball-gathering assembly, and the number of ball-gathering needles cannot accurately match the number of balls, thereby affecting the efficiency of the ball-gathering needle in dividing and gathering the bearing balls. The utility model can adjust the number of ball-gathering needles used according to the number of balls inside the bearing, thereby facilitating the ball-gathering needle to accurately divide the balls and improve the efficiency of dividing and gathering the balls, and at the same time can clean the ball-gathering needle to prevent the ball-gathering needle from contaminating the balls when dividing and gathering the balls.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision ball-gathering structure for a bearing, comprising a ball-gathering lateral shifting rod, a lateral shifting cylinder is installed on one side of the ball-gathering lateral shifting rod, a ball-gathering optical axis is connected to the inside of the ball-gathering lateral shifting rod, a linear bearing is sleeved on the outer surface of the ball-gathering optical axis, a stepper motor is connected to the upper end of the ball-gathering optical axis, a coupling is connected to one end of the stepper motor, and a ball-gathering assembly is installed inside the ball-gathering lateral shifting rod;

[0008] The lower end of the ball dividing and gathering optical axis is connected to a support block, a storage groove is provided inside the support block, a storage block is connected inside the storage groove, a limiting groove is provided on the outer surface of the storage block, a return spring is connected inside the storage block, the other end of the return spring is connected to a slider, the outer surface of the slider is fixedly connected to the limiting block, the interior of the storage block is fixedly connected to a fixing rod, the lower end of the slider is connected to a ball dividing needle, the outer surface of the ball dividing needle is provided with a groove, the lower surface of the support block is connected to a fixing block, a connecting spring is welded inside the fixing block, the other end of the connecting spring is connected to a connecting rod, and one end of the connecting rod is connected to a cleaning cotton.

[0009] Through the above technical scheme, the transverse cylinder drives the ball dividing and gathering transverse shifting rod to move, and the ball dividing and gathering optical axis and the ball dividing and gathering assembly are driven to the specified position through the ball dividing and gathering transverse shifting rod. The stepper motor drives the ball dividing and gathering optical axis to move, and the ball dividing and gathering work is performed through the ball dividing and gathering bearing balls. The ball dividing and gathering accuracy is improved through the transmission of the coupling and the guidance of the linear bearing.

[0010] Furthermore, the slider forms a telescopic structure inside the storage block through a return spring, the limiting groove is an inverted "Z"-shaped structure, and the depth of the limiting groove is less than the length of the limiting block.

[0011] Through the above technical scheme, the ball dividing needle is rotated to drive the slider to rotate, and the limit block connected to the slider slides inside the limit groove, pushing the ball dividing needle into the storage block, so that the ball dividing needle is stored in the storage block. The limit groove with a "Z"-shaped structure can limit the slider connected to the limit block to prevent the ball dividing needle connected to the slider from falling off from the storage block. The ball dividing needle can be used or stored by adjusting its position, thereby ensuring that the number of ball dividing needles used is consistent with the number of balls inside the bearing, which is beneficial for the ball dividing needle to accurately divide and gather the balls.

[0012] Furthermore, a plurality of ball dividing needles are provided, and the ball dividing needles are centrally symmetrically distributed with respect to the longitudinal center line of the support block.

[0013] Through the above technical solution, multiple balls inside the bearing can be separated and gathered by multiple ball separation needles, which is beneficial to improving the efficiency of the ball separation and gathering work.

[0014] Furthermore, the length of the ball dividing needle is smaller than the length of the storage block, and the lower end of the ball dividing needle is in a needle tip structure.

[0015] Through the above technical solution, the ball dividing needle with a needle tip structure can be accurately inserted between two adjacent balls to perform ball dividing and gathering work, and the ball dividing needle can be stored through the storage block to prevent the excess storage blocks from causing damage to the bearing balls.

[0016] Furthermore, the ball dividing needle is connected to the slider in a rotational manner, the groove is a spiral structure, and the groove is connected to the fixing rod.

[0017] By adopting the above technical solution, when the ball dividing needle is pushed into the interior of the storage block, since the groove is a spiral structure and under the action of the fixing rod, the ball dividing needle and the slider will rotate during the lifting and lowering process of the ball dividing needle.

[0018] Furthermore, the connecting rod forms a telescopic structure inside the fixed block through a connecting spring, and the length of the connecting rod is greater than the horizontal distance from the ball dividing needle to the fixed block.

[0019] Through the above technical solution, the connecting spring pushes the cleaning cotton connected to the connecting rod to clean the ball dividing needle and absorb the lubricating oil adhered to the outer surface of the ball dividing needle, thereby preventing the subsequent ball dividing needle from contaminating the ball when dividing and gathering the balls.

[0020] Furthermore, the cleaning cotton is an arc-shaped sheet structure, a plurality of the cleaning cottons are provided, and the cleaning cottons correspond to the ball dividing needles one by one.

[0021] Through the above technical solution, the cleaning cotton with an arc-shaped sheet structure can fit tightly with the ball dividing needle, thereby facilitating the cleaning cotton to perform precise cleaning of the ball dividing needle.

[0022] Compared with the prior art, the utility model provides a high-precision ball-gathering structure for a bearing, which has the following beneficial effects:

[0023] In the utility model, the ball dividing needle is rotated to make the limit block connected to the slider slide inside the limit groove, and the ball dividing needle is pushed toward the inside of the storage block, so that the ball dividing needle can be stored inside the storage block, thereby ensuring that the number of ball dividing needles used is consistent with the number of balls inside the bearing. The balls are accurately divided and gathered by multiple ball dividing needles, which is beneficial to improving the efficiency of the ball dividing and gathering work. In this process, since the groove has a spiral structure and under the action of the fixed rod, the ball dividing needle and the slider will rotate, and at the same time, the connecting spring pushes the cleaning cotton connected to the connecting rod to clean the rotating ball dividing needle, which is beneficial to avoid the lubricating fluid adhered to the outer surface of the ball dividing needle from contaminating the balls when the balls are divided and gathered.

[0034] See also Figure 1-Figure 7The lower end of the ball dividing and gathering optical axis 6 is connected to a supporting block 8, a receiving groove 9 is provided inside the supporting block 8, a receiving block 10 is connected inside the receiving groove 9, a limiting groove 12 is provided on the outer surface of the receiving block 10, a return spring 11 is connected inside the receiving block 10, a slider 13 is connected at the other end of the return spring 11, a limiting block 14 is fixedly connected to the outer surface of the slider 13, a fixing rod 17 is fixedly connected inside the receiving block 10, a ball dividing needle 15 is connected to the lower end of the slider 13, a groove 16 is provided on the outer surface of the ball dividing needle 15, a fixing block 18 is connected to the lower surface of the supporting block 8, a connecting spring 19 is welded inside the fixing block 18, a connecting rod 20 is connected to the other end of the connecting spring 19, and a cleaning cotton 21 is connected to one end of the connecting rod 20.

[0035] The principle of separating and gathering the bearing balls is as follows: the transverse cylinder 2 drives the ball-separating and gathering transverse shift rod 1 to move, and the ball-separating and gathering optical axis 6 and the ball-separating and gathering assembly 7 are driven to the specified position through the ball-separating and gathering transverse shift rod 1, the stepper motor 4 drives the ball-separating and gathering optical axis 6 to move, and the ball-separating and gathering work is performed on the bearing balls through the ball-separating needle 15, and the ball-separating and gathering accuracy is improved through the transmission of the coupling 5 and the guidance of the linear bearing 3.

[0036] See also Figure 1-Figure 7 The slider 13 forms a telescopic structure inside the storage block 10 through the return spring 11. The limiting groove 12 is an inverted "Z"-shaped structure. The depth of the limiting groove 12 is less than the length of the limiting block 14. There are multiple ball dividing needles 15, and the ball dividing needles 15 are centrally symmetrically distributed about the longitudinal center line of the support block 8. The length of the ball dividing needle 15 is less than the length of the storage block 10, and the lower end of the ball dividing needle 15 is a needle tip structure.

[0037] The principle of being able to adjust the number of ball dividing needles 15 used is: rotating the ball dividing needle 15 allows the limit block 14 connected to the slider 13 to slide inside the limit groove 12, and pushing the ball dividing needle 15 into the interior of the storage block 10 allows it to be stored inside the storage block 10, thereby adjusting the number of ball dividing needles 15 used, so that the number of ball dividing needles 15 used is consistent with the number of ball bearings inside the bearing, which is conducive to the precise insertion of multiple ball dividing needles 15 between two adjacent ball bearings to perform ball dividing and gathering work, thereby improving the efficiency of the ball dividing and gathering work.

[0039] It should be noted that: since the groove 16 is a spiral structure, under the action of the fixing rod 17 , the ball dividing needle 15 and the slider 13 will rotate during the process of the ball dividing needle 15 rising and falling inside the storage block 10 .

[0040] See also Figure 1-Figure 3 and Figure 6 The connecting rod 20 forms a telescopic structure inside the fixed block 18 through the connecting spring 19.

A plurality of cleaning cottons 21 are provided, and the cleaning cottons 21 correspond to the ball dividing needles 15 one by one.

[0041] It is worth mentioning that: the connecting spring 19 pushes the arc-shaped cleaning cotton 21 connected to the connecting rod 20 to move horizontally, so that the cleaning cotton 21 fits tightly against the ball dividing needle 15, and the cleaning cotton 21 absorbs the lubricating oil adhered to the outer surface of the ball dividing needle 15, thereby preventing the subsequent ball dividing needle 15 from contaminating the ball when dividing and gathering the balls.
