DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes. Example

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic structural diagram of a first embodiment of a wheel hub manipulator rotating mechanism provided by the utility model; Figure 2 A schematic diagram of the structure of the hub manipulator rotating mechanism provided by the utility model; Figure 3 for Figure 2 A schematic cross-sectional view of the rotating frame shown; Figure 4 A side schematic diagram of the hub manipulator rotation mechanism provided by the utility model; Figure 5 for Figure 2 The bottom view of the rotating frame is shown. The hub manipulator rotating mechanism comprises: a supporting frame 1b;

[0025] A first servo motor 2b is installed on the support frame 1b, a screw rod 3b is rotatably connected to the support frame 1b, a movable frame 4b is threadedly connected to the outer surface of the screw rod 3b, a second servo motor 5b is installed on the movable frame 4b, a rotating frame 6b is fixedly connected to the output shaft of the second servo motor 5b, a first moving plate 7b and a second moving plate 8b are slidably connected to the rotating frame 6b, a reciprocating structure 9b is arranged between the first moving plate 7b and the second moving plate 8b, clamping wheels 10b are installed at the bottom of the first moving plate 7b and the second moving plate 8b, a cylinder 11b is fixedly connected to the rotating frame 6b, and the output end of the cylinder 11b is fixedly connected to the first moving plate 7b.

[0026] The first servo motor 2b is connected to the screw rod 3b via a transmission assembly, and the moving frame 4b is connected to the supporting frame 1b in a sliding manner.

[0027] The reciprocating structure 9b includes a rotating wheel 9b1 and two driving rods 9b2, the rotating wheel 9b1 is rotatably connected to the rotating frame 6b, one end of the two driving rods 9b2 are rotatably connected to the rotating wheel 9b1, and the other ends of the two driving rods 9b2 are rotatably connected to the first moving plate 7b and the second moving plate 8b respectively.

[0028] The extension of the cylinder 11b can drive the first moving plate 7b to move, so that one of the driving rods 9b2 is stretched, driving the rotating wheel 9b1 to rotate, so that the other driving rod 9b2 pushes the second moving plate 8b to move away.

[0029] The material of the clamping wheel 10b is polyurethane to avoid scratching the product, and the opening and closing strokes of the clamping wheel 10b meet the needs of different products.

[0030] The working principle of the hub manipulator rotating mechanism provided by the utility model is as follows:

[0031] The extension of the cylinder 11b causes the first moving plate 7b and the second moving plate 8b to move apart and unfold, and then the rotation of the first servo motor 2b drives the screw rod 3b to rotate, so that the moving frame 4b moves downward to the top of the wheel hub, and then the contraction of the cylinder 11b causes the first moving plate 7b and the second moving plate 8b to move relative to each other, so that the clamping wheel 10b clamps the wheel hub and fixes it, and then the first servo motor 2b rotates in the opposite direction, indirectly causing the moving frame 4b to move upward, so that the rotating frame 6b moves upward to lift the wheel hub, and the rotation of the second servo motor 5b can drive the rotating frame 6b to rotate, so that the wheel hub rotates for position adjustment and then enters the subsequent fixture inlay station.

[0032] Compared with the related art, the hub manipulator rotating mechanism provided by the utility model has the following beneficial effects:

[0033] The grabbing module composed of the first moving plate 7b and the second moving plate 8b adopts a linked pneumatic clamp to ensure concentric clamping each time; the clamp clamps the upper wheel waist, and the clamp wheel 10b, which is the part in contact with the product, is made of polyurethane material to avoid scratching the product. The opening and closing stroke of the clamp meets the needs of different products, which facilitates the clamping of the wheel hub and can adjust the position of the wheel hub, ensuring that the wheel hub can better cooperate with the fixture inlay station and can be better aligned, while reducing the labor intensity of the staff and eliminating the safety hazards that exist during manual construction by the staff. Example

[0034] Please refer to Figure 6Based on the wheel hub manipulator rotation mechanism provided in the first embodiment of the present application, the second embodiment of the present application proposes another wheel hub manipulator rotation mechanism. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0035] Specifically, the difference of the wheel hub manipulator rotation mechanism provided in the second embodiment of the present application is that two auxiliary rods 12b are penetrated through the rotating frame 6b, and the two auxiliary rods 12b are slidably connected to the rotating frame 6b, and a contact plate 13b is fixedly connected between the bottom ends of the two auxiliary rods 12b, and two telescopic rods 14b are installed on the top of the contact plate 13b, and a pressure plate 15b is fixedly connected between the top ends of the two telescopic rods 14b, and two compression springs 16b are arranged between the pressure plate 15b and the rotating frame 6b, and a pressure sensor 17b is installed at the bottom of the rotating frame 6b.

[0036] The pressure sensor 17b is electrically connected to the cylinder 11b.

[0037] A protection pad 18b is fixedly connected to the bottom of the contact plate 3b. The protection pad 18b can protect the wheel hub when contacting the wheel hub, thereby avoiding scratching the wheel hub.

[0038] The material of the protection pad 18b is rubber or sponge.

[0039] Compared with the related art, the hub manipulator rotating mechanism provided by the utility model has the following beneficial effects:

[0040] As the rotating frame 6b moves downward to prepare to clamp the wheel hub, the contact plate 13b will move downward with the rotating frame 6b. When the contact plate 13b contacts the wheel hub, the contact plate 13b will be pressed by the wheel hub and generate slight pressure, thereby through the reaction force of the compression spring 16b, the pressure plate 15b generates pressure on the pressure sensor 17b, thereby controlling the action of the cylinder 11b, so that the clamping wheel 10b moves to clamp the wheel hub, which can play a detection role and ensure that when the contact plate 13b contacts the wheel hub, the clamping wheel 10b immediately clamps the wheel hub, so that the clamping wheel 10b can be accurately clamped at the upper wheel waist position of the wheel hub, avoiding the displacement of the clamping position of the clamping wheel 10b.

[0041] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
