In this embodiment, the transfer device 8 is a pneumatic sliding table, and other structures with similar functions may be adopted in practice according to circumstances.

Referring to fig. 4-5, the floating measurement device 7 includes a support 9, an upper limit block 10 is disposed at an upper end of the support 9, a rod hole 11 is formed in the upper limit block 10, and a vertical adjustment rod 12 is inserted into the rod hole 11. The top end of the adjusting rod 12 is provided with a limiting piece 13, and a floating spring 14 is sleeved on the adjusting rod 12 between the limiting piece 13 and the upper limiting piece 10. The lower end of the adjusting rod 12 is provided with a sliding measuring head frame 15, and the sliding measuring head frame 15 is slidably arranged on the support 9. In this embodiment, the support 9 is provided with a vertical guide rail 16, the guide rail 16 is provided with a slider 17, and the sliding head measuring frame 15 is arranged on the slider 17. The sliding head stock 15 can slide up and down along the guide rail 16.

The sliding measuring head frame 15 is provided with a rotatable swing measuring head frame 18, the swing measuring head frame 18 is positioned at the side end of the sliding measuring head frame 15, and the rotating shaft of the swing measuring head frame 18 is in the horizontal direction. In this embodiment, the sliding head frame 15 is provided with a spindle 19, and the swinging head frame 18 is provided on the spindle 19 through a bearing 20. The pendulum head frame 18 is able to perform a pendulum rotation relative to the sliding head frame 15 via the bearing 20. The swing head measuring frame 18 is provided with a dust cover 21 opposite to the bearing 20 to protect the bearing 20 and facilitate later maintenance and repair. In this embodiment, the left and right ends of the sliding head-measuring rack 15 are respectively provided with a side baffle 22, and the two side baffles 22 are respectively located at two sides of the swinging head-measuring rack 18. A limit spring 23 is arranged between the side baffle 22 and the swing measuring head frame 18, and four limit springs 23 are arranged in the limit spring 23 and are respectively positioned above and below two sides of the swing measuring head frame 18. When the swing measuring head frame 18 swings, the limit spring 23 can perform a certain buffering function on the swing measuring head frame, and can also promote the reset of the swing measuring head frame 18.

The lower end of the swing measuring head frame 18 is provided with a fixed measuring head 24, and the upper end of the swing measuring head frame 18 is provided with a movable measuring head 25. In this embodiment, two fixed measuring heads 24 are provided, so that the fixed measuring heads can be ensured to be always in close contact with the workpiece 31 in the rotating process, and the measuring result is ensured not to be influenced by rotation. In this embodiment, the top end of the fixed probe 24 is set to be slightly higher than the surface of the rotary measuring platform 2 by 0.5mm, so that the fixed probe 24 is gradually pressed down by the workpiece 31 when the fixed probe 24 moves toward the workpiece 31.

An automatic blanking device and a blanking conveying device 26 are arranged on the side of the rotary measuring platform 2, and the automatic blanking device is used for transferring the workpiece 31 on the rotary measuring platform 2 to the blanking conveying device 26. In this embodiment, the automatic blanking device includes a second material sensor 27 and a blanking cylinder 28. The second material sensor 27 is disposed at a feeding end of the blanking conveying device 26, and is used for determining whether there is a workpiece 31, in this embodiment, the second material sensor 27 employs a photoelectric switch, and other similar sensing devices may be employed as required in practice. The blanking cylinder 28 is connected with a blanking pull rod 29, the end of the blanking pull rod 29 and the blanking conveying device 26 are respectively located on two sides of the rotary measuring platform 2, and the end of the blanking pull rod 29 is equal to the height of a workpiece 31 on the rotary measuring platform 2. The cylinder drives the blanking pull rod 29 to reciprocate, so that the workpiece 31 on the rotary measuring platform 2 is pushed to the blanking conveying device 26. The blanking conveying device 26 is a roller conveying device, and the blanking air cylinder 28 is arranged on the roller conveying device and is positioned below the conveying rollers.

The driving device, the transferring device 8, the movable measuring head 25, the automatic blanking device and the blanking conveying device 26 are respectively in control connection with a controller 30, and the controller 30 controls the whole device to work.

In the operation of the embodiment, the first material sensor 6 determines whether there is a workpiece 31 on the rotary measuring platform 2, and if there is no workpiece 31, a supporting feeding device, such as a robot, places the workpiece 31 on the rotary measuring platform 2 and sends a start detection signal to the controller 30. The controller 30 starts the pneumatic sliding table to drive the floating measuring device 7 to approach the workpiece 31 to be measured, the fixed measuring head 24 contacts the lower surface of the workpiece 31 firstly, and because the fixed measuring head is slightly higher than the lower surface of the workpiece 31 by 0.5mm, the fixed measuring head 24 is pressed down by the lower surface of the product in the approaching process, and under the action of the floating spring 14, the whole floating measuring device 7 floats, so that the floating measuring device 7 gradually moves downwards after approaching, and the fixed measuring head 24 is adapted to the lower surface of the workpiece 31. The movable probe 25 then begins to contact the upper surface of the workpiece 31 for measurement purposes.

After the pneumatic sliding table is in place, the pneumatic sliding table sends a signal in place to the controller 30, then the rotating motor 3 starts to rotate to drive the rotating main shaft 4 and the rotating measuring platform 2 to rotate, and further the workpiece 31 to be measured is driven to rotate, and therefore the thickness of the whole workpiece 31 in one circle is detected. In the rotation detection process, if the over-tolerance point occurs, the detection is stopped, the controller 30 outputs an alarm signal, and then the unqualified workpiece 31 is removed under manual intervention. After the rotation detection process, if the workpiece 31 is qualified, the controller 30 checks the signal of the second material sensor 27 to determine whether the blanking conveying device 26 is full of material, if so, waits, and if not, sends a signal to the blanking cylinder 28 to pull the blanking pull rod 29 to pull the workpiece 31 to be detected onto the blanking conveying device 26.

The adjusting screw and the floating spring 14 are used in cooperation, the position of the sliding measuring head frame 15 can be adjusted, the fixed measuring head 24 is slightly higher than the surface of the rotary measuring platform 2 by 0.5mm when not measuring, and the fixed measuring head can be contacted with the lower surface of the workpiece 31 when measuring. The floating spring 14 generates elastic force to ensure a certain pressure between the fixed measuring head 24 and the workpiece 31, and ensures that the fixed measuring head cannot be separated in the rotating process. The bearing 20 and the mandrel 19 enable the swing measuring head frame 18 to rotate freely within a small angle, and the fixed measuring head 24 can fluctuate along with the fluctuation of the bottom surface of the workpiece 31, so that a good measuring effect is ensured.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
