The cylinder body of the lifting cylinder 15 is fixedly installed on the bottom of the support plate 10 by bolts, and the piston rod of the lifting cylinder 15 extends upward and is fixedly connected to the lifting plate 12 by bolts. The lifting plate 12 can be driven to move up and down by the extension and contraction of the lifting cylinder 15.

[0035] A turntable 18 is provided on the top of the lifting plate 12, which is driven by a driving device and rotates around its own axis. The axis of the turntable 18 extends vertically, and the turntable 18 is coaxially arranged with the lifting plate 12. The bottom of the turntable 18 is fixed with a coaxially arranged rotating shaft 16 by bolts, and the rotating shaft 16 is rotatably mounted on the lifting plate 12 through bearings; a plurality of universal ball transfers 17 evenly spaced around the rotating shaft 16 are fixed on the top of the lifting plate 12 by bolts, and the universal ball transfers 17 are supported on the bottom of the turntable 18 to improve the stability of the rotation of the turntable 18.

[0036] The drive device includes a drive motor 19 mounted on the bottom of the lifting plate 12 by bolts. A driving bevel gear 20 is fixedly mounted on the rotating shaft of the drive motor 19. A driven bevel gear 21 is fixedly mounted on the lower end of the rotating shaft 16 and meshes with the driving bevel gear 20. The driving bevel gear 20 is driven by the drive motor 19 to rotate, and the driving bevel gear 20 then drives the rotating shaft 16 and the turntable 18 to rotate through the driven bevel gear 21.

[0037] A coaxially arranged support column 22 is fixed on the top of the turntable 18 by bolts. The diameter of the support column 22 is smaller than the interval between two adjacent conveying rollers 3. A long strip-shaped supporting plate 23 is fixed on the upper end of the support column 22 by bolts. The supporting plate 23 is located between two adjacent conveying rollers 3. A clamping component for clamping the workpiece to be polished is movably installed on the top of the supporting plate 23.

[0038] like Figure 6As shown, the supporting plate 23 is provided with two slide grooves 24 extending along its length direction, and the two slide grooves 24 are respectively located on opposite sides of the support column 22, and the slide groove 24 vertically penetrates the supporting plate 23; the clamping component includes a slide seat 25 slidably installed in the two slide grooves 24, and a guide rod 26 extending in the same direction is also fixedly installed in the slide groove 24 by bolts, and the slide seat 25 is slidably sleeved on the guide rod 26; the upper end of the slide seat 25 extends out from the top of the supporting plate 23, and the upper ends of the two slide seats 25 are respectively fixed with a clamping plate 27 by bolts on the side close to each other. In this embodiment, the side of the two clamping plates 27 close to each other is an arc shape that coincides with the outer circumferential surface of the wheel hub 38; a clamping cylinder 28 is also installed in the slide groove 24, and the cylinder body of the clamping cylinder 28 is fixedly installed on the inner wall of the slide groove 24 by bolts, and the piston rod of the clamping cylinder 28 extends along the length direction of the slide groove 24 and is fixedly connected to the corresponding slide seat 25.

[0039] When in use, the wheel hub 38 is conveyed by the roller conveyor 1. In the initial state, the top of the supporting plate 23 is lower than the top of the conveying roller 3, and the supporting plate 23 will not hinder the roller conveyor 1 from driving the wheel hub 38 to move; when the wheel hub 38 moves to the top of the supporting plate 23, the roller conveyor 1 stops driving the wheel hub 38 to move, and then drives the lifting plate 12 and the turntable 18 to rise as a whole through the lifting cylinder 15, and the turntable 18 drives the supporting plate 23 to move upward through the support column 22 until the supporting plate 23 is completely moved to the top of the conveying roller 3 At the top, the bottom of the wheel hub 38 is lifted upward by the supporting plate 23; then the two clamping cylinders 28 contract and drive the two slides 25 to approach each other, and the two slides 25 drive the two clamping plates 27 to clamp the wheel hub 38 inward, so as to clamp and fix the wheel hub, and then the top of the wheel hub 38 can be polished by the polishing mechanism 4. During the polishing process, the turntable 18 can also be driven to rotate by the driving motor 19, and the turntable 18 drives the supporting plate 23 to rotate through the support column 22, so as to adjust the angle of the wheel hub 38.

[0040] In this embodiment, two auxiliary support plates 30 driven to rise and fall by an adjusting cylinder 29 are further provided on the top of the turntable 18. The two auxiliary support plates 30 are respectively located on the front and rear sides of the supporting plate 23, and the auxiliary support plates 30 are located between two adjacent conveying rollers 3; two adjusting cylinders 29 are respectively arranged at intervals on the bottom of each auxiliary support plate 30, and the cylinder body of the adjusting cylinder 29 is fixedly mounted on the turntable 18 by bolts, and the piston rod of the adjusting cylinder 29 extends upward and is fixedly mounted on the auxiliary support plate 30 by bolts.

[0041] In the initial state, if Figure 2 and Figure 3As shown, the top of the auxiliary support plate 30 is flush with the top of the supporting plate 23. When the lifting cylinder 15 drives the lifting plate 12 and the turntable 18 to rise, the turntable 18 first drives the supporting plate 23 and the two auxiliary support plates 30 to move upward synchronously, and the supporting plate 23 and the two auxiliary support plates 30 simultaneously support the bottom of the wheel hub 38 and drive the wheel hub 38 to lift upward smoothly, so as to avoid uneven force on the wheel hub 38 and cause it to tilt. When the supporting plate 23 is completely moved to the top of the conveying roller 3 and the wheel hub 38 is clamped by the two clamping plates 27, the auxiliary support plate 30 is driven to move to the bottom of the conveying roller 3 by contracting the adjusting cylinder 29, as shown in FIG. Figure 8 As shown, the adjustment cylinder 29 and the auxiliary support plate 30 are prevented from interfering with the conveying roller 3 and hindering the rotation of the support plate 23.

[0042] Two cylinder supports 31 arranged opposite to each other are fixed on the top of the frame 2 corresponding to the position of the clamping mechanism by bolts. A clamping cylinder 32 is installed on each of the two cylinder supports 31. The cylinder bodies of the clamping cylinders 32 are fixed on the corresponding cylinder supports 31 by bolts. The piston rods of the two clamping cylinders 32 extend toward each other. Figure 7 As shown, a mounting bracket 33 is fixedly installed on the piston rod of the clamping cylinder 32 by bolts, and two mounting plates 34 are respectively provided on the side where the two mounting brackets 33 are close to each other and are arranged opposite to each other. A plurality of support wheels 35 are rotatably installed between the two mounting plates 34 of the same mounting bracket 33, and the axis of the support wheel 35 extends vertically. The plurality of support wheels 35 are distributed along an arc that fits the outer wall of the hub 38, and one side of the support wheel 35 is exposed outside the end of the mounting plate 34 away from the mounting bracket 33.

[0043] When the supporting plate 23 is completely moved to the top of the conveying roller 3 and the wheel hub 38 is clamped by the two clamping plates 27, the two clamping cylinders 32 are extended to drive the two mounting frames 33 to approach each other, and the mounting frames 33 drive the supporting wheels 35 thereon to fit the outer circumference of the wheel hub 38. In the process of the turntable 18 driving the supporting plate 23 and the wheel hub 38 to rotate, the multiple supporting wheels 35 can provide support for the wheel hub 38, thereby improving the stability of the rotation of the wheel hub 38.

[0044] An inverted L-shaped bracket 36 is provided on one side of the roller conveyor 1. The lower end of the vertical part of the bracket 36 is fixed to the ground, and the horizontal part of the bracket 36 extends to the top of the roller conveyor 1. An identification camera 37 is fixedly installed on the horizontal part of the bracket 36 and is located directly above the clamping mechanism 9. When the identification camera 37 detects that the wheel hub 38 moves to directly above the support plate 23, the roller conveyor 1 stops driving the wheel hub 38 to move, and clamps the wheel hub 38 through the clamping mechanism 9.
