After the turning and milling, the spindle 58 is reset by the second screw slide module 57, and then the second screw slide module 57 is moved by the sliding module 54 away from the bottom of the wheel rim. At this time, the sliding module 54 drives the first screw slide module 55 to move, and then the hardness tester 56 is driven to move by the first screw slide module 55, so that the hardness tester 56 measures the hardness value of the wheel rim.

[0028] Two support rods 61 are fixedly connected to the inner side of one end of the module mounting frame 1, and the first fixing columns 62 are fixedly connected to the top ends of the two support rods 61, and the second fixing columns 63 are fixedly connected to the top of the first fixing columns 62. The outer side of the first fixing columns 62 is connected to a placement plate 64, and the outer side of the second fixing columns 63 is movably sleeved with a telescopic spring 65, which is located between the placement plate 64 and the top of the first fixing columns 62. The top of the placement plate 64 is provided with a through groove 66; the clamping column 410 is driven by the profile lock 47 The inner wheel rim moves so that it moves to the top of the placement plate 64, and then the piston rod of the second cylinder 45 is reset, so that the clamping column 410 drives the wheel rim to move downward, so that the bottom of the wheel rim contacts the top of the placement plate 64, and the wheel rim is fixed to the top of the placement plate 64 by the clamping column 410. During this process, the placement plate 64 is subjected to force, and the placement plate 64 moves outside the second fixing column 63, so that the telescopic spring 65 is compressed, and the placement plate 64 is given an upward force by the telescopic spring 65, so that the wheel rim is fixed more firmly.

[0029] A mounting plate is fixedly connected to one side of the module mounting frame 1, a rodless cylinder 71 is fixedly connected to one side of the mounting plate, a first slide 72 is slidably connected to the outer side of the rodless cylinder 71, a connecting frame 73 is fixedly connected to the outer side of the first slide 72, a slide rail 74 is fixedly connected to one side of the mounting plate below the rodless cylinder 71, a second slide 75 is slidably connected to the outer side of the slide rail 74, a push rod 76 is hinged at one end of the second slide 75, a mini cylinder 77 is movably connected to one side of the connecting frame 73, and the piston rod of the mini cylinder 77 is movably connected to the push rod 76. The outside of the wheel rim is moved by the first slide 72 on the rodless cylinder 71, so that the push rod 76 moves to the rear side of the wheel rim, and the piston rod of the mini cylinder 77 is extended, and the push rod 76 is turned over by the piston rod of the mini cylinder 77, so that the push rod 76 rotates to a horizontal state, so that the push rod 76 is located behind the wheel rim, and the first slide 72 is moved by the rodless cylinder 71, so that the first slide 72 drives the push rod 76 to contact the outside of the wheel rim, and the wheel rim is pushed by the push rod 76 to move above the placement plate 64, so that the wheel rim proceeds to the next process.

[0030] The working principle or structural principle is that when in use, the car wheel rim enters into the interior of the device and moves to the top of the transmission module 2. When the wheel rim moves to the top of the finger cylinder 36, the cylinder clamp 37 is located on the outside of the wheel rim. The cylinder clamp 37 is driven to move by the finger cylinder 36, so that the cylinder clamp 37 clamps the wheel rim. Then, by controlling the piston rod of the first cylinder 33 to extend, the piston rod of the first cylinder 33 pushes the sliding frame 39 to move on the inner side of the fixed frame 32, so that the connecting seat 35 drives the wheel rim to move upward through the finger cylinder 36, so that the wheel rim is separated from the top of the transmission module 2. The output shaft of the servo motor 38 drives the connecting seat 35 to rotate through the gear box 34, so that the wheel rim rotates 360 degrees. The wheel hub is scanned by the barcode scanner 9 to identify the model of the wheel hub.

[0031] By resetting the piston rod of the second cylinder 45, the piston rod of the second cylinder 45 drives the lower end of the Z-axis slide rail 44 to move downward, and the Z-axis slide rail 44 drives the first connecting plate 46 to move downward, so that the clamping column 410 moves to the outside of the wheel rim.

[0032] The finger cylinder 36 is controlled to drive the cylinder clamp 37 to reset, so that the cylinder clamp 37 is separated from the outer side of the wheel rim, and then the piston rod of the first cylinder 33 is reset, so that the sliding frame 39 drives the cylinder clamp 37 on the finger cylinder 36 to reset, and the piston rod of the second cylinder 45 is extended, so that the clamping column 410 drives the wheel rim to move upward, and then the Z-axis connecting frame 43 moves above the X-axis slider 42, so that the Z-axis connecting frame 43 drives the Z-axis slide rail 44 to move, so that the profile lock 47 drives the clamping column 410 to move upward. The wheel rim on the side moves so that it moves to the top of the placement plate 64, and then the piston rod of the second cylinder 45 is reset, so that the clamping column 410 drives the wheel rim to move downward, so that the bottom of the wheel rim contacts the top of the placement plate 64, and the wheel rim is fixed to the top of the placement plate 64 by the clamping column 410. During this process, the placement plate 64 is subjected to force, and the placement plate 64 moves outside the second fixing column 63, so that the telescopic spring 65 is compressed, and the placement plate 64 is given an upward force by the telescopic spring 65, so that the wheel rim is fixed more firmly.

[0033] At this time, the wheel rim can be turned and milled by the spindle 58 on the second screw slide module 57. After the turning and milling, the spindle 58 is reset by the second screw slide module 57, and then the second screw slide module 57 is moved away from the bottom of the wheel rim by the sliding module 54. At this time, the sliding module 54 drives the first screw slide module 55 to move, and then the first screw slide module 55 drives the hardness tester 56 to move, so that the hardness tester 56 can measure the hardness value of the wheel rim. After the measurement is completed, the piston rod of the third cylinder 49 is reset, so that the U-shaped slider 48 moves on the outside of the profile lock 47, so that the U-shaped slider 48 drives the clamping column 410 to separate from the outside of the wheel rim, and then the piston rod of the third cylinder 49 is extended, so that the piston rod of the third cylinder 49 drives the Z-axis slide rail 44 to move upward, so that the profile lock 47 drives the clamping column 410 to move upward, and then moves on the X-axis slide rail 41 through the Z-axis connecting frame 43, driving the clamping column 410 to reset.

[0034] The first slide 72 on the rodless cylinder 71 is moved, so that the push rod 76 moves to the rear side of the wheel rim, and the piston rod of the mini cylinder 77 is extended, and the piston rod of the mini cylinder 77 drives the push rod 76 to flip, so that the push rod 76 rotates to a horizontal state, so that the push rod 76 is located behind the wheel rim, and the first slide 72 is moved by the rodless cylinder 71, so that the first slide 72 drives the push rod 76 to contact the outside of the wheel rim, and the wheel rim is pushed by the push rod 76 to move above the placement plate 64, so that the wheel rim proceeds to the next process.

[0035] Through the above settings, no human intervention is required throughout the process, unmanned production can be realized, and the requirements of random inspection or full inspection during production can be met. In addition, the automated measurement is stable and reliable, and will not affect the quality of the product due to errors caused by manual operation.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
