[0013] 3. By driving the connecting plate to move horizontally towards one side of the positioning chuck, the connecting plate causes the arc-shaped pusher plate to move horizontally synchronously.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figure 1-10 As shown, the present invention provides a positioning device for milling and machining automobile wheel hubs, including a machining table 1. A positioning chuck 11 is fixedly installed on the upper surface of the machining table 1. The positioning chuck 11 can clamp and position automobile wheel hub blanks. This is prior art and will not be described in detail here. An equipment groove 14 is opened on the upper surface of the machining table 1. A transmission device 15 is provided on the inner wall of the equipment groove 14. The transmission belt of the transmission device 15 is horizontally aligned with the upper surface of the machining table 1. A movable groove 16 is opened on the surface of the machining table 1. A pushing mechanism 2 is provided in the movable groove 16. A feeding mechanism 4 is provided on the upper surface of the machining table 1. A driving mechanism 6 for the pushing mechanism 2 and the feeding mechanism 4 is provided on the lower surface of the machining table 1.

[0028] By adopting the above technical solution, after the forged car wheel hub is placed on the upper surface of the conveyor belt of the conveyor device 15, the conveyor belt transports the car wheel hub to the upper surface of the processing table 1 as the conveyor device 15 operates. By setting the pushing mechanism 2, the pushing mechanism 2 pushes a single car wheel hub horizontally to the axial position on the upper surface of the positioning chuck 11, thereby facilitating the automatic feeding of the car wheel hub. By setting the feeding mechanism 4, the feeding mechanism 4 facilitates the rotation of multiple car wheel hubs, making it easy for the pushing mechanism 2 to push a single car wheel hub, thereby facilitating the continuous feeding of the car wheel hub. By setting the driving mechanism 6, the driving mechanism 6 enables the pushing mechanism 2 and the feeding mechanism 4 to work together.

[0029] A milling device 12 is fixedly installed on the side of the machining table 1 near the positioning chuck 11, and a support frame 13 is fixedly installed on the side of the machining table 1 away from the positioning chuck 11. An inclined groove 17 is provided on the side of the machining table 1 near the milling device 12.

[0030] By adopting the above technical solution and setting the inclined groove 17, after the processing of the car wheel hub on the upper surface of the positioning chuck 11 is completed, the pushing mechanism 2 pushes the car wheel hub blank, the car wheel hub blank enters the upper surface of the positioning chuck 11, and pushes the processed car wheel hub into the interior of the inclined groove 17. The setting of the inclined groove 17 facilitates the unloading of the processed car wheel hub.

[0031] The pushing mechanism 2 includes an arc-shaped pushing plate 21. The lower surface of the arc-shaped pushing plate 21 is in contact with the upper surface of the processing table 1. A connecting plate 22 is fixedly installed on the lower surface of the arc-shaped pushing plate 21. The connecting plate 22 passes through the movable groove 16 and is in contact with the inner wall of the movable groove 16. A U-shaped seat 26 is fixedly installed on one side of the connecting plate 22. A first rotating shaft 27 is rotatably installed on the inner wall of the U-shaped seat 26. A push rod 28 is fixedly installed on the outer wall of the first rotating shaft 27.

[0032] By adopting the above technical solution, by driving the push rod 28 to move for one cycle, the push rod 28 causes the connecting plate 22 and the arc-shaped push plate 21 to move horizontally toward the positioning chuck 11 and return to the initial position via the first rotating shaft 27 and the U-shaped seat 26. The connecting plate 22 moves horizontally along the inner wall of the movable groove 16. At the same time, the arc-shaped push plate 21 pushes the car wheel hub blank between two adjacent feeding rotating plates 42 and pushes the car wheel hub blank to the axial position on the upper surface of the positioning chuck 11.

[0033] An L-shaped frame plate 23 is fixedly installed on the lower surface of the processing table 1. A guide groove 24 is provided on the upper surface of the L-shaped frame plate 23. A guide block 25 is slidably connected to the inner wall of the guide groove 24. One end of the connecting plate 22 away from the arc-shaped pusher plate 21 is fixedly connected to the upper surface of the guide block 25.

[0034] By adopting the above technical solution, by setting up an L-shaped frame plate 23, a guide groove 24 and a guide block 25, the guide groove 24 and the guide block 25 guide the connecting plate 22 and the arc-shaped pusher plate 21 in the horizontal direction, so that the connecting plate 22 and the arc-shaped pusher plate 21 keep moving in the horizontal direction.

[0035] A first rotating rod 29 is rotatably mounted on the lower surface of the processing table 1. A rotating disk 3 is fixedly mounted on the end of the first rotating rod 29 away from the processing table 1. A drive rod 31 is fixedly mounted on the side of the rotating disk 3 away from the first rotating rod 29. The end of the drive rod 31 away from the rotating disk 3 is rotatably connected to the end of the push rod 28. A first transmission rod 32 is rotatably mounted on the side of the processing table 1 close to the first rotating rod 29. A first transmission wheel 33 is fixedly mounted on the outer wall of the first transmission rod 32 and the outer wall of the first rotating rod 29. A first transmission belt 34 is connected between the two first transmission wheels 33. A first gear 35 is fixedly mounted on the end of the first transmission rod 32 away from the processing table 1.

[0036] By adopting the above technical solution, the first gear 35 is driven to rotate, which in turn causes the first transmission rod 32 to rotate. The first transmission rod 32 causes the first rotating rod 29 to rotate through the two first transmission wheels 33 and the first transmission belt 34. The first rotating rod 29 causes the driving rod 31 to rotate around the axis of the rotating disk 3 through the rotating disk 3. The driving rod 31 causes the push rod 28 to reciprocate.

[0037] The feeding mechanism 4 includes a fixed base 41, one end of which is in movable contact with the upper surface of the processing table 1. A feeding turntable 42 arranged in a ring array is fixedly installed on the outer wall of the fixed base 41. The lower surface of the feeding turntable 42 is in movable contact with the upper surface of the processing table 1. A through groove 44 is opened on the surface of the feeding turntable 42. Two arc-shaped limiting plates 45 are provided inside the through groove 44. An arc-shaped anti-slip pad 46 is fixedly installed on the inner wall of the arc-shaped limiting plate 45. Two second rotating shafts 47 are rotatably installed on the inner wall of the through groove 44. A connecting sleeve 48 is fixedly installed on the outer wall of the second rotating shaft 47. A connecting seat 49 is fixedly installed on the outer wall of the connecting sleeve 48. One side of the connecting seat 49 is fixedly connected to the outer wall of the arc-shaped limiting plate 45. Torsion springs 5 ​​are movably sleeved on both ends of the second rotating shaft 47. One end of two adjacent torsion springs 5 ​​is fixedly connected to the inner wall of the through groove 44, and the other end of two adjacent torsion springs 5 ​​is fixedly connected to the upper and lower surfaces of the connecting seat 49.

[0038] By adopting the above technical solution, when the conveying device 15 conveys the automobile wheel hub blank between two adjacent feeding turntables 42, the outer wall of the conveyed automobile wheel hub contacts the inner wall of the two arc-shaped anti-slip pads 46. As the conveying device 15 conveys, the two arc-shaped limiting plates 45 change angles around the axes of the two second rotating shafts 47 via the two connecting seats 49 and the two connecting sleeves 48. When the axis of the automobile wheel hub blank is at the center position of the two arc-shaped limiting plates 45, the four torsion springs 5 ​​return to their original position, and the two arc-shaped limiting plates are fixed by the two second rotating shafts 47, the two connecting sleeves 48, and the two connecting seats 49. Plate 45 returns to its initial state, and the inner walls of the two curved anti-slip pads 46 are completely in contact with the outer wall of the car wheel hub blank. The two curved limiting plates 45 limit the car wheel hub blank through the two curved anti-slip pads 46, improving the stability of the car wheel hub blank. When the fixed seat 41 rotates, the fixed seat 41 causes multiple feeding rotating plates 42 to rotate around the axis of the fixed seat 41. The multiple feeding rotating plates 42 cause the limited car wheel hub blank to rotate synchronously around the axis of the fixed seat 41. As the car wheel hub blank is rotated to the front side of the curved push plate 21, the pushing operation of the car wheel hub blank can be realized.

[0039] The surface of the feeding turntable 42 is provided with a through slot 43, and the arc-shaped push plate 21 and the through slot 43 cooperate with each other.

[0040] By adopting the above technical solution and by setting the through slot 43, when the feeding turntable 42 rotates around the axis of the fixed seat 41, the through slot 43 avoids the feeding turntable 42 in the rotating state from colliding with the arc-shaped push plate 21.

[0041] A second rotating rod 51 is rotatably mounted on the lower surface of the processing table 1. One end of the second rotating rod 51 is fixedly connected to one end of the fixed base 41. A second transmission rod 52 is rotatably mounted on the side of the processing table 1 near the second rotating rod 51. A second transmission wheel 53 is fixedly mounted on the outer wall of the second transmission rod 52 and the end of the second rotating rod 51 away from the processing table 1. A second transmission belt 54 is connected between the two second transmission wheels 53. A second gear 55 is fixedly mounted on the end of the second transmission rod 52 away from the processing table 1.

[0042] By adopting the above technical solution, the second gear 55 is driven to rotate, which in turn causes the second transmission rod 52 to rotate. The second transmission rod 52 then causes the second rotating rod 51 to rotate via two second transmission wheels 53 and a second transmission belt 54. The second rotating rod 51 then causes the fixed base 41 to rotate.

[0043] The drive mechanism 6 includes a servo motor 61. A third rotating rod 63 is fixedly installed at the drive output end of the servo motor 61. The end of the third rotating rod 63 away from the servo motor 61 is rotatably connected to the lower surface of the processing table 1. A sector gear 64 is fixedly installed on the outer wall of the third rotating rod 63. The sector gear 64 and the first gear 35 are meshed and connected. The sector gear 64 and the second gear 55 are horizontally corresponding.

[0044] By adopting the above technical solution, by turning on the servo motor 61, the drive shaft of the servo motor 61 causes the third rotating rod 63 to rotate, the third rotating rod 63 causes the sector gear 64 to rotate, the sector gear 64 drives the first gear 35 to rotate, and when the sector gear 64 disengages from the first gear 35, the sector gear 64 meshes with the second gear 55 and drives the second gear 55 to rotate, thereby realizing the cooperative operation of the pushing mechanism 2 and the feeding mechanism 4 to complete the feeding of batch automotive wheel hub blanks one by one.

[0045] An L-shaped bracket 62 is fixedly mounted on the outer wall of the servo motor 61, and the upper surface of the L-shaped bracket 62 is fixedly connected to the lower surface of the processing table 1.

[0046] By adopting the above technical solution, and by setting up an L-shaped fixing bracket 62, the stability of the servo motor 61 is improved.

[0047] Working principle: When a batch of raw automotive wheel hubs needs to be milled, the operator first uses the conveyor device 15 to transport the batch of raw automotive wheel hubs. When a raw automotive wheel hub enters between two adjacent feeding plates 42, the outer wall of the raw automotive wheel hub contacts the inner wall of the two adjacent curved anti-slip pads 46 and pushes the two curved anti-slip pads 46. As the conveyor device 15 transports the material, the two adjacent curved limiting plates 45 change angles around the axis of the corresponding second rotating shaft 47 via two connecting seats 49 and two connecting sleeves 48. After the shaft is positioned at the center of the two arc-shaped limiting plates 45, the four torsion springs 5 ​​are reset, and the two arc-shaped limiting plates 45 are restored to their initial state through the two second rotating shafts 47, the two connecting sleeves 48, and the two connecting seats 49. At this time, the inner walls of the two arc-shaped anti-slip pads 46 and the outer walls of the car wheel hub blank are completely in contact. The two adjacent arc-shaped limiting plates 45 limit the car wheel hub blank through the two arc-shaped anti-slip pads 46, thus conveniently realizing the limiting of the car wheel hub blank during the feeding process, thereby effectively improving the stability of the car wheel hub blank during subsequent rotating feeding.

[0048] At this time, the operator shuts off the transmission device 15 and turns on the servo motor 61. The drive shaft of the servo motor 61 causes the third rotating rod 63 to rotate, which in turn causes the sector gear 64 to rotate. The sector gear 64 drives the first gear 35 to rotate. After the sector gear 64 disengages from the first gear 35, it meshes with the second gear 55 and drives it to rotate. The second gear 55 causes the second transmission rod 52 to rotate. The second transmission rod 52, through two second transmission wheels 53 and a second transmission belt 54, causes the second rotating rod 51 to rotate. The second rotating rod 51 causes the fixed base 41 to rotate, and the fixed base 41 causes multiple feeding rotors to rotate. Plate 42 rotates around the axis of fixed base 41. Multiple feeding plates 42 cause the limited car wheel hub blanks to rotate synchronously around the axis of fixed base 41. When sector gear 64 disengages from second gear 55 and meshes with first gear 35, sector gear 64 drives second gear 55 to rotate once. Two adjacent feeding plates 42 rotate 18 degrees and are horizontally aligned with positioning chuck 11. At this time, multiple feeding plates 42 stop rotating. During this period, the transmission device 15 continues to transmit car wheel hub blanks, so that multiple car wheel hub blanks enter between two adjacent feeding plates 42 respectively.

[0049] When a piece of raw car wheel hub material is rotated to the front of the curved pusher plate 21, as the sector gear 64 disengages from the second gear 55 and the first gear 35, the multiple feeding turntables 42 stop rotating. Simultaneously, the sector gear 64 drives the first gear 35 to rotate, which in turn causes the first transmission rod 32 to rotate. The first transmission rod 32, through two first transmission wheels 33 and a first transmission belt 34, causes the first rotating rod 29 to rotate. The first rotating rod 29, through the rotating disk 3, causes the drive rod 31 to rotate around the axis of the rotating disk 3. The drive rod 31 causes the push rod 28 to move one cycle. During this period, the push rod 28 causes the connecting plate 22 and the arc-shaped push plate 21 to move horizontally toward the positioning chuck 11 via the first rotating shaft 27 and the U-shaped seat 26 and then back to the initial position. The arc-shaped push plate 21 pushes the car wheel hub blank between two adjacent feeding rotating plates 42 and pushes the car wheel hub blank to the axial position on the upper surface of the positioning chuck 11, thereby facilitating the automatic feeding of the car wheel hub blank, effectively improving the convenience of feeding the car wheel hub blank, and at the same time, effectively improving the efficiency of milling the car wheel hub blank, and saving the operating cost of manual feeding.
