Description

Technical Field

[0001] The invention relates to the technical field of bearing production, in particular to a ball loading machine for a retaining rack of an automobile hub bearing. Background Art

[0002] The main function of automobile wheel hub bearings is to bear weight and provide precise guidance for the rotation of the wheel hub. It bears both axial load and radial load, and is an important component to ensure the smooth and safe driving of the car. The automobile wheel hub bearing cage ball loading machine is an important equipment used for the ball loading operation of automobile wheel hub bearing cages. Its working principle is mainly based on rolling friction and precise assembly. During the ball loading process, the balls are accurately loaded into the raceway of the cage through specific mechanisms and devices. Most of the existing automobile wheel hub bearing cage ball loading machines are provided with arc-shaped long holes with the same number of steel balls to be installed in the bearing. When the gate at the storage box is opened, the steel balls roll through the arc-shaped long holes to reach the bearing cage to complete the installation. In order to avoid the steel balls from getting stuck or causing channel blockage, the diameter of the arc-shaped long holes is generally larger than the diameter of the steel balls, thereby ensuring that the steel balls can be smoothly exported. However, in actual use, when the number of steel balls in the storage box is large, the export speed and interval of the steel balls will be affected by the acceleration of gravity. At the moment the gate is opened, the steel balls will quickly pass through the gate under the action of gravity, resulting in a situation where the number of exported steel balls is inconsistent. If the gate is a solenoid valve, it may be squeezed with the steel balls being exported at the moment the gate is closed, and the gate cannot be closed normally. Abnormal vibration, noise or temperature increase may occur, posing certain safety hazards. Summary of the invention

The continued rotation of the rotating chamber gradually closes the ball inlet hole, and other steel balls can be squeezed out of the rotating chamber during the closing process. At this time, there is only one steel ball in the rotating chamber, and the steel ball can be exported from the rotating chamber and introduced into the cavity of the bearing half shell cage through the feeding hose. The steel ball installation is completed, avoiding the situation that the number of exported steel balls is inconsistent, and there is no need to use an electromagnetic valve for control, avoiding the possibility that the electromagnetic valve gate may be squeezed with the exported steel balls at the moment of closing, and the gate cannot be closed normally; 2.

When the rotating chamber starts to rotate, the second rotating shaft starts to rotate accordingly, and pushes the first transmission rod through the eccentric wheel and the hinge shaft. The first transmission rod pushes the first slider to move under the restriction of the first slide groove through the telescopic rod. Since the first slide groove is inclined, the first slider will pull the folded part of the telescopic rod to extend it during the movement. At the same time, with the movement of the first slider, the ball pushing plate gradually rises and passes through the pushing plate moving groove opened on the rotating chamber. Due to the existence of the pushing plate moving groove, the ball pushing plate will not affect the normal rotation of the rotating chamber. At the same time, the pushing plate can contact the steel ball and push the steel ball into the feeding hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, an automobile hub bearing cage ball loading machine. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In order to solve the problem that when there are a large number of steel balls in the storage box, the export speed and interval of the steel balls will be affected by the acceleration of gravity. The steel balls will quickly pass through the gate under the action of gravity at the moment the gate is opened, resulting in a discrepancy in the number of exported steel balls. If the gate is a solenoid valve, it may be squeezed with the steel balls being exported at the moment the gate is closed, and the gate cannot be closed normally, which may cause abnormal vibration, noise or temperature rise, and there are certain safety hazards. The present invention proposes a car hub bearing cage ball loading machine, such as Figure 1 - Fig. 20 As shown: The billiard machine body 10 includes a base 11, a liftable frame 12 arranged on the base 11, and a conveyor belt 13 arranged below the frame 12. The bearing half shell 20 is placed on the conveyor belt 13. A ball feeding mechanism 30 is installed on the frame 12. The ball feeding mechanism 30 includes a rotatable shell 31 installed at the bottom of the frame 12, a plurality of first rotating grooves 32 inside the shell 31, and a steel ball storage cavity 33 connected to the first rotating grooves 32. The first rotating grooves 32 contain steel balls. When the equipment is started, the conveyor belt 13 will transport the bearing half shell 20 without steel balls installed to the bottom of the frame 12. At this time, the frame 12 descends to a suitable position, the shell 31 starts to rotate, and at the same time, the steel balls in the steel ball storage cavity 33 are guided to the retaining frame of the bearing half shell 20 through a feeding hose 34. As the shell 31 rotates, the steel balls can be sequentially inserted into the cavities of each retaining frame. In order to drive the housing 31 to rotate, a driving mechanism 60 is provided in the middle of the housing 31. Figure 4 and Figure 6 As shown, the driving mechanism 60 includes a mounting column 61 installed in the middle of the frame 12 and penetrating the middle of the housing 31, a servo motor 62 is installed at the bottom of the mounting column 61, a linkage rod 63 is installed on the output end of the servo motor 62, and the linkage rod 63 is connected to the housing 31; The ball feeding mechanism 30 also includes a first rotating groove 32 arranged on the frame 12. The shell 31 is rotatably embedded in the first rotating groove 32 and driven to rotate by the servo motor 62. Through this design, when the servo motor 62 is started, it can drive the shell 31 to rotate under the restriction of the first rotating groove 32, and the feeding hose 34 can deliver the steel balls to the retaining frame in sequence.

[0019] In order to avoid the phenomenon that the number of steel balls exported is inconsistent due to the excessively fast steel ball export speed, an anti-blocking mechanism 40 is provided inside the steel ball storage chamber 33. Figure 7 and Figure 8As shown, the anti-blocking mechanism 40 includes a guide plate 41 located at the bottom of the steel ball storage chamber 33 and a rotatable rotating chamber 42 arranged in the guide plate 41. The surface of the rotating chamber 42 is provided with a ball entry hole 43 with the same outer diameter as the steel ball. When the ball entry hole 43 rotates to the top with the rotating chamber 42, the steel ball enters the rotating chamber 42. The rotating chamber 42 continues to rotate to close the ball entry hole 43. The surface of the ball entry hole 43 is provided with a surrounding ball pushing plate moving groove 431, as shown in FIG. Fig. 9 As shown; In the process of guiding the steel balls from the steel ball storage chamber 33 to the feeding hose 34 in sequence, the steel balls will gather to the top of the guide plate 41 under the action of gravity. In order to improve the gathering effect of the guide plate 41 on the steel balls, the inner edge of the guide plate 41 is set as an inclined surface that gradually decreases from top to bottom, and the bottom of the guide plate 41 is also provided with an arc slope with the end ends located at both sides of the ball inlet hole 43. The steel balls gather on both sides of the ball inlet hole 43 under the guidance of the arc slope. At this time, the ball inlet hole 43 is fully opened with the rotation of the rotating chamber 42, and the steel balls can enter the rotating chamber 42 through the ball inlet hole 43 and are blocked. The other steel balls continue to be introduced and the continued rotation of the rotating chamber 42 causes the ball entry hole 43 to gradually close. During the closing process, other steel balls can also be squeezed out of the rotating chamber 42. At this time, there is only one steel ball in the rotating chamber 42, which can be led out from the rotating chamber 42 and introduced into the cavity of the retaining frame of the bearing half shell 20 through the feeding hose 34. The installation of the steel balls is completed, avoiding the situation where the number of steel balls led out is inconsistent, and there is no need to use an electromagnetic valve for control, which avoids the situation that the electromagnetic valve gate may be squeezed with the steel ball being led out at the moment of closing, and the gate cannot be closed normally.

[0020] In order to further prevent the steel ball outlet speed from being affected by the inclination angle of the pipeline, the rotating chamber 42 can be horizontally arranged inside the guide plate 41. At this time, in order to be able to push the steel ball in the rotating chamber 42 into the feeding hose 34, as shown in FIG. Figure 7 As shown, a pushing mechanism 50 is provided below the ball entry hole 43, and the pushing mechanism 50 includes a mounting chamber 51 provided at the bottom of the guide plate 41, an inclined first slide groove 58 provided in the mounting chamber 51, and a ball pushing plate 59 moving along the length direction of the first slide groove 58; When the ball inlet 43 is in a fully open state, the ball pushing plate 59 is located outside the rotating chamber 42. When the rotating chamber 42 starts to rotate, the second rotating shaft 52 starts to rotate accordingly, and pushes the first transmission rod 55 through the eccentric wheel 53 and the hinge shaft 54. The first transmission rod 55 pushes the first slider 57 to move under the restriction of the first slide groove 58 through the telescopic rod 56. Since the first slide groove 58 is inclined, the first slider 57 will pull the folded part of the telescopic rod 56 to extend it during the movement. At the same time, with the movement of the first slider 57, the ball pushing plate 59 gradually rises and passes through the ball pushing plate moving groove 431 opened on the rotating chamber 42. Due to the existence of the ball pushing plate moving groove 431, the ball pushing plate 59 will not affect the normal rotation of the rotating chamber 42. At the same time, the ball pushing plate 59 can contact the steel ball and push the steel ball into the feeding hose 34.

[0021] The ball pushing plate 59 pushes out the steel ball through the moving groove 431 of the ball pushing plate in cooperation with the rotation of the rotating chamber 42. The movement of the ball pushing plate 59 and the rotation of the rotating chamber 42 need to be performed simultaneously. In order to achieve this purpose, Figure 7 As shown, the anti-blocking mechanism 40 further includes a first rotating shaft 44 connected to the rotating chamber 42, a motor is installed at the bottom of the guide plate 41, the output end of the motor is connected to the first rotating shaft 44, and a first bevel gear 441 is sleeved and installed on the first rotating shaft 44; The second rotating shaft 52 is sleeved with a second bevel gear 521 meshing with the first bevel gear 441. When the motor is started, the rotating cavity 42 is driven to rotate through the first rotating shaft 44. At the same time, the first rotating shaft 44 drives the second rotating shaft 52 to rotate synchronously through the cooperation of the first bevel gear 441 and the second bevel gear 521.

[0022] In order to process different types of bearing half shells 20, it is necessary to adjust the outlet position of the feeding hose 34 according to the position of the retainer on the bearing half shell 20, such as Fig.12 - Fig.14 As shown, the bottom of the housing 31 is provided with the same number of regulating chambers 311 as the feeding hoses 34 and corresponding in position, the outlet end of the feeding hoses 34 is located in the regulating chamber 311, and a variable pitch mechanism 70 is provided below the regulating chamber 311; The pitch changing mechanism 70 includes a bottom plate 71 installed at the bottom of the adjusting chamber 311 and a plurality of second slide grooves 72 provided on the bottom plate 71. A second slider 73 is slidably embedded in the second slide groove 72. A positioning frame 74 sleeved at the outlet end of the feeding hose 34 is provided on the second slider 73. The position of the steel ball dropped through the feeding hose 34 changes with the movement of the second slider 73. The movement of the second slider 73 is controlled by the linkage rod 63. An adjustment mechanism 80 is provided in the adjustment cavity 311. The adjustment mechanism 80 includes an annular second rotating groove 81 provided in the adjustment cavity 311 and a rotating disk 82 rotatably embedded in the second rotating groove 81. The rotating disk 82 is controlled to rotate by the linkage rod 63. A plurality of arc-shaped guide grooves 83 are provided on the rotating disk 82. A slide 84 is slidably embedded in the guide groove 83. When the rotating disk 82 rotates, the guide groove 83 pushes the slide 84 to move. An adjusting rod 85 is fixedly installed in the middle of the slide 84, and the adjusting rod 85 is connected to the positioning frame 74. When the slide 84 moves, the adjusting rod 85 drives the second slide block 73 to move horizontally along the length direction of the second slide groove 72; When the linkage rod 63 drives the turntable 82 to rotate, the linkage rod 63 no longer drives the shell 31 to rotate. At this time, the turntable 82 can push the slide 84 through the guide groove 83 under the restriction of the second rotating groove 81, so that the slide 84 drives the positioning frame 74 to move through the adjusting rod 85. The positioning frame 74 can only move along the length direction of the second slide groove 72 under the restriction of the second slide groove 72 and the second slider 73. With the movement of the position of the positioning frame 74, the feeding hose 34 connected to the positioning frame 74 can gradually move into the adjusting chamber 311, thereby achieving the purpose of changing the position of the outlet end of the feeding hose 34, so that it can adapt to the assembly operations of bearing half shells 20 of various sizes and different numbers of steel balls.

[0023] At the same time, in order to realize the switching between the linkage rod 63 controlling the rotation of the housing 31 and the control of the rotation of the rotating disk 82, as shown in FIG. Fig.14 - Fig.17 As shown, the linkage rod 63 includes a rod body 631 connected to the output end of the servo motor 62, and the upper and lower ends of the rod body 631 are respectively sleeved with a turntable connecting ring 821 connected to the turntable 82 and a bottom plate connecting ring 711 connected to the bottom plate 71; A plurality of lifting rods 632 are embedded in the rod body 631, and the lifting rods 632 are connected by assembly rings 635; The upper and lower ends of the lifting rod 632 are respectively provided with an upper clamping block 633 engaged with the turntable connecting ring 821 and a lower clamping block 634 engaged with the bottom plate connecting ring 711. The surface of the rod body 631 is provided with through holes for the upper clamping block 633 and the lower clamping block 634 to move. When the upper clamping block 633 rises, the upper clamping block 633 is engaged with the turntable connecting ring 821, and the engagement between the bottom plate connecting ring 711 and the lower clamping block 634 is released. At this time, the output end of the servo motor 62 drives the turntable connecting ring 821 to rotate only through the rod body 631, and the turntable The disk 82 rotates through the turntable connecting ring 821 to adjust the outlet position of the feeding hose 34. When the upper clamping block 633 descends, the engagement between the upper clamping block 633 and the turntable connecting ring 821 is released, and at the same time, the bottom plate connecting ring 711 is engaged with the lower clamping block 634. At this time, the output end of the servo motor 62 drives the bottom plate connecting ring 711 to rotate through the rod body 631, and the bottom plate connecting ring 711 drives the adjusting chamber 311 to rotate through the bottom plate 71, thereby achieving the purpose of driving the housing 31 to rotate, and completing the switching of the control of the linkage rod 63. In order to adjust the position of the upper block 633 more conveniently, Fig.18 - Fig. 20 As shown, the assembly ring 635 is controlled by a switching mechanism 90, and the switching mechanism 90 includes a positioning rod 91 arranged at the bottom of the rod body 631, a guide pin 92 is arranged in the middle of the positioning rod 91, and a spring 93 is wound around the surface of the guide pin 92; A push plate 95 is inserted into the bottom of the rod body 631 to push the assembly ring 635 to move. The push plate 95 pushes the lifting rod 632 to move through the assembly ring 635. A sleeve rod 96 is provided in the middle of the push plate 95 to engage with the guide pin 92. By moving the push plate 95, the push plate 95 drives the sleeve rod 96 to be inserted into the bottom of the rod body 631. At this time, the sleeve rod 96 squeezes the spring 93 under the guidance of the guide pin 92 to make it produce elastic deformation. At the same time, the push plate 95 contacts the assembly ring 635 to push the lifting rod 632 to rise, thereby completing the adjustment of the position of the lifting rod 632 and completing the switching of the control of the linkage rod 63. A plurality of limiting grooves 94 are formed on the inner wall of the positioning rod 91, and the limiting grooves 94 include a vertical moving section and an arc section; The outer wall of the sleeve rod 96 is provided with a limit block 97 that cooperates with the limit groove 94. During the process of inserting the push plate 95, the limit block 97 set on the sleeve rod 96 can be driven to insert into the vertical moving section first. After reaching the end of the vertical moving section, the push plate 95 is rotated to make the limit block 97 rotate into the arc section for fixation. The positions of the limit block 97 and the sleeve rod 96 are fixed, and the push plate 95 can continuously apply a lifting force to the assembly ring 635 to ensure that the upper clamping block 633 and the turntable connecting ring 821 are engaged for a long time.
