Description
Technical Field

[0002] Ball pins are key components that ensure the stability of automobile handling, the smoothness, comfort, safety of driving, and the correct and accurate driving of the automobile. They are also called ball hinges and ball joints. At present, there are many ball pins in ball hinge assemblies such as automobile steering control arms, ball head suspensions, and steering tie rods. When ball pins are connected to other components, they often need to use cotter pin holes.
[0003] The grinding of ball pins is generally done directly with a grinding disc or a grinding roller, but this grinding method has poor grinding accuracy, and small burrs will remain on the surface of the workpiece after grinding. These fine burrs are generally small particles attached to the surface of the workpiece after rough grinding. Once attached to the surface, once a large force or friction force is applied, scratches will appear on the surface of the workpiece. Moreover, the ball pin is divided into a ball head and a rod-shaped structure. Traditionally, it is impossible to grind all positions of multiple ball pins at one time, which causes inconvenience in use and low processing efficiency. Utility Model Content

[0025] Reference Figure 1-4A deburring device for ball pin assembly processing comprises a bottom plate 1, a fixing rod 2 is fixedly mounted on the surface of the bottom plate 1, an electric telescopic rod 3 is fixedly mounted on the surface of the fixing rod 2, a mounting shell 4 is fixedly mounted on the output port of the electric telescopic rod 3, a brush 6 is arranged inside the mounting shell 4, a bottom shell 7 is fixedly mounted on the surface of the bottom plate 1, a first connecting roller 12 and a second connecting roller 13 are rotatably connected inside the bottom shell 7, a driving mechanism for driving the first connecting roller 12 and the second connecting roller 13 to rotate is arranged on the side wall of the bottom shell 7, the ball pin is directly placed on the surface of the first connecting roller 12 and the second connecting roller 13 during use, and the first connecting roller 12 and the second connecting roller 13 are driven by the driving mechanism to rotate Rotation, and there is friction between the ball pin body and the first connecting roller 12 and the second connecting roller 13, so the rotation of the first connecting roller 12 and the second connecting roller 13 can make the ball pin body rotate, and at this time the electric telescopic rod 3 is used to drive the mounting shell 4 to move downward, and the mounting shell 4 drives the brush 6 to move downward, so that the brush 6 is in contact with the ball pin body. Since the brush 6 is used for deburring, when the brush 6 passes through the surface of the part, the numerous brush filaments can be bent arbitrarily and naturally fit the contour of the workpiece, and enter the groove hole and other places that are difficult for general tools to enter to remove the burrs. When the brush 6 passes through the part, the force applied to the processed surface is not enough to produce cutting, and it only has a polishing effect on the processed surface, which will not affect the processing size of the part.
[0026] Furthermore, a receiving groove 11 is opened on the top of the bottom shell 7, and the first connecting roller 12 and the second connecting roller 13 are arranged inside the receiving groove 11. By setting the receiving groove 11, when the ball pin body is placed on the surface of the first connecting roller 12 and the second connecting roller 13, it is also located inside the receiving groove 11, so that during the grinding process with the brush 6, the burrs brushed off are also located inside the receiving groove 11, reducing the occurrence of splashing.
[0027] Furthermore, the driving mechanism includes two connecting shafts 8, both of which are rotatably connected to the accommodating groove 11, and one end of the two connecting shafts 8 rotates through the bottom shell 7, and a second motor 9 is fixedly installed on the side wall of the bottom shell 7. A driving turntable 16 and a driven turntable 15 are respectively fixedly installed on the surfaces of the two connecting shafts 8. The driving turntable 16 and the driven turntable 15 are connected by a belt drive, and the output shaft port of the second motor 9 is fixedly connected to one of the connecting shafts 8. When the driving mechanism is in use, the second motor 9 is started, and the second motor 9 drives the connecting shaft 8 to rotate. The two connecting shafts 8 rotate synchronously through the driving turntable 16, the driven turntable 15 and the belt, thereby driving the first connecting roller 12 and the second connecting roller 13 to rotate, and then the ball pin body on the surface rotates.
[0028] Furthermore, the diameter of the first connecting roller 12 is larger than the diameter of the second connecting roller 13, and the rotation direction of the second connecting roller 13 is toward the first connecting roller 12. Since the ball pin body is arranged between the first connecting roller 12 and the second connecting roller 13, and the diameter of the first connecting roller 12 is larger, when the first connecting roller 12 and the second connecting roller 13 rotate toward one side, the ball pin body will not rotate off the first connecting roller 12 and the second connecting roller 13, which is convenient for use.
[0029] Furthermore, a slot 14 is provided on the side wall of the bottom shell 7, the slot 14 is connected to the receiving groove 11, a collection box 10 is slidably inserted inside the slot 14, and waste chips can be collected conveniently by providing the slot 14 and the collection box 10 in the slot 14.
[0030] Furthermore, a first motor 5 is fixedly mounted on the side wall of the mounting shell 4 , a brush 6 is rotatably connected inside the mounting shell 4 , and an output shaft port of the first motor 5 is fixedly connected to the brush 6 .
[0031] In summary, during use, the ball pin is directly placed on the surface of the first connecting roller 12 and the second connecting roller 13, and the driving mechanism is used to drive the first connecting roller 12 and the second connecting roller 13 to rotate. There is friction between the ball pin body and the first connecting roller 12 and the second connecting roller 13, so the rotation of the first connecting roller 12 and the second connecting roller 13 can make the ball pin body rotate. At this time, the electric telescopic rod 3 is used to drive the mounting shell 4 to move downward, and the mounting shell 4 drives the brush 6 to move downward, so that the brush 6 contacts with the ball pin body. Since the brush 6 is used for deburring, when the brush 6 passes through the surface of the part, the numerous brush wires can be bent arbitrarily, naturally fit to the contour of the workpiece, enter the groove hole and other places that are difficult for general tools to enter, and remove the burrs. When the brush 6 passes through the part, the force on the processed surface is not enough to produce cutting, and it only polishes the processed surface, which will not affect the processing size of the part. By setting the accommodating groove 11, the ball pin body is placed on the first connecting The surfaces of the rollers 12 and the second connecting roller 13 are also located inside the receiving groove 11, so that the burrs brushed off during the grinding process with the brush 6 are also located inside the receiving groove 11, reducing the occurrence of splashing. When the driving mechanism is in use, the second motor 9 is started, and the second motor 9 drives the connecting shaft 8 to rotate. The two connecting shafts 8 rotate synchronously through the active turntable 16, the driven turntable 15 and the belt, thereby driving the first connecting roller 12 and the second connecting roller 13 to rotate, and then the ball pin body on the surface rotates. Since the ball pin body is arranged between the first connecting roller 12 and the second connecting roller 13, and the diameter of the first connecting roller 12 is larger, when the first connecting roller 12 and the second connecting roller 13 rotate toward one side, the ball pin body will not rotate off the first connecting roller 12 and the second connecting roller 13, which is convenient for use. By setting the slot 14 and setting the collection box 10 in the slot 14, it is convenient to collect waste chips.
