[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Figures 1 to 5An embodiment of the utility model of the vibration detection device of the rotating body with a tapered hole is shown. The vibration detection device of the rotating body with a tapered hole in this embodiment includes a detection table assembly 1, a measuring mechanism 2 and a rotating drive member 3 (such as a servo motor, etc.) for driving the detection table assembly 1 to rotate. The detection table assembly 1 includes a first frustum 11 and a second frustum 12 which are coaxially arranged and have different diameters. The first frustum 11 is slidably connected to the second frustum 12.

[0028] The present embodiment of the vibration detection device of the rotary body with a tapered hole, wherein the detection table assembly 1 includes a first truncated cone 11 and a second truncated cone 12 which are coaxially arranged and of different sizes, and the first truncated cone 11 and the second truncated cone 12 are slidably connected. When the rotary body workpiece 7 with a tapered hole is placed on the detection table assembly 1, it first contacts the outer diameter line of the small truncated cone, and then continues to move axially until it contacts the outer diameter line of the large truncated cone, completing the material placement. Placing the workpiece 7 by the outer diameter lines of the two truncated cones can play a good centering role, and the structure of the small truncated cone floating along the axial direction can be compatible with workpieces 7 with different inner tapered hole sizes. It has a simple structure, is easy to use, has good compatibility, helps to reduce equipment costs, avoids frequent replacement, and is also conducive to improving production efficiency.

[0029] Furthermore, in this embodiment, the first truncated cone 11 includes a coaxially arranged first truncated cone portion 111 and a connecting rod 112, the diameter of the connecting rod 112 is smaller than the diameter of the first truncated cone portion 111, the second truncated cone 12 includes a coaxially arranged second truncated cone portion 121 and a connecting tube 122, the diameter of the connecting tube 122 is smaller than the diameter of the second truncated cone portion 121, the diameters of the first truncated cone portion 111 and the second truncated cone portion 121 are not equal, and the connecting rod 112 extends into the connecting tube 122. When the rotating workpiece 7 with a conical hole is placed on the inspection table assembly 1, it first contacts the outer diameter line of the small truncated cone, and then continues to move axially until it contacts the outer diameter line of the large truncated cone, completing the material placement. Placing the workpiece 7 by the outer diameter lines of the two truncated cones can play a good centering role, and the cooperation of the connecting rod 112 and the connecting tube 122 realizes the structure of the small truncated cone floating along the axial direction, which can be compatible with workpieces 7 with different inner cone hole sizes, and the structure is simple and effective.

[0030] As a preferred embodiment, the first truncated cone portion 111 is located above the second truncated cone portion 121 and has a diameter smaller than that of the second truncated cone portion 121. An elastic member (not shown in the figure, for example, a spiral spring, elastic rubber, etc.) is provided in the connecting tube 122. The lower end of the connecting rod 112 abuts against the elastic member, that is, in this embodiment, the detection table assembly 1 adopts a vertical structure. Of course, in other embodiments, the detection table assembly 1 may also adopt other arrangements. When the workpiece 7 is placed on the detection table assembly 1, it first contacts the outer diameter line of the first truncated cone portion 111. Later, because the weight of the workpiece 7 overcomes the elastic force of the elastic member, the first truncated cone 11 is pressed downward until the workpiece 7 contacts the outer diameter line of the second truncated cone portion 121 to complete the placement of the workpiece 7. The small truncated cone floats up and down to be compatible with workpieces 7 with different inner cone hole sizes. After the workpiece 7 is detected and taken out, the elastic force of the elastic member drives the first truncated cone 11 to rise and reach a balanced state.

[0031] Furthermore, in this embodiment, a limiting groove 113 is provided on the connecting rod 112, and a limiting member 123 (preferably a limiting screw, or a limiting pin, etc.) is provided on the side wall of the connecting tube 122, and the limiting member 123 extends into the limiting groove 113. The limiting member 123 cooperates with the limiting groove 113 to limit the relative rotation of the first truncated table 11 and the second truncated table 12, so that the rotating driving member 3 drives the two to rotate synchronously for detection.

[0032] Furthermore, in this embodiment, the connection rod 112 and the connection tube 122 are clearance-matched, so as to facilitate the movement of the first truncated table 11 relative to the second truncated table 12 to complete the placement of the workpiece 7 .

[0033] Furthermore, in this embodiment, a partition 4 is provided between the detection platform assembly 1 and the measuring mechanism 2, and a passage 41 is provided on the partition 4 for the measuring mechanism 2 to pass through (specifically, for the displacement sensor 21 of the measuring mechanism 2 to pass through). The partition 4 can play a certain shielding and protective role, preventing the workpiece 7 from colliding with the measuring mechanism 2 when being placed on the detection platform assembly 1 or taken out, and also improving the aesthetics of the device.

[0034] Furthermore, in this embodiment, the measuring mechanism 2 includes a displacement sensor 21 and a measuring drive 22 (cylinder, electric push rod, etc.) for driving the displacement sensor 21 to move back and forth. During measurement, the measuring drive 22 drives the displacement sensor 21 to extend from the channel 41 and rests against the position of the workpiece 7 that needs to be detected. The rotating drive 3 drives the workpiece 7 to rotate through the detection table assembly 1, and the runout value of the workpiece 7 is measured by the change in the reading of the displacement sensor 21. The structure is simple and effective. After the detection is completed, the measuring drive 22 drives the displacement sensor 21 to withdraw from the channel 41.

[0035] Furthermore, in this embodiment, the measuring mechanism 2 further includes a movable guide rail 23 and a slider 24 disposed on the movable guide rail 23, and the displacement sensor 21 is connected to the slider 24. The movable guide rail 23 can provide a guide for the slider 24, ensuring that the slider 24 and the displacement sensor 21 move steadily and smoothly, and ensuring high motion accuracy.

[0036] Furthermore, in this embodiment, the measuring mechanism 2 is disposed on a lifting platform 5. The lifting platform 5 can be used to drive the measuring mechanism 2 to rise and fall, and realize height adjustment, so as to measure different height positions of the workpiece 7, and can also adapt to workpieces 7 of different heights.

[0037] Furthermore, in this embodiment, the vibration detection device of the rotary body with a tapered hole further includes a dotting pen 61, and a dotting driving member 62 (such as a cylinder, an electric push rod, etc.) for driving the dotting pen 61 to move back and forth is provided on the lifting platform 5. According to the measurement data of the measuring mechanism 2, the dotting driving member 62 drives the dotting pen 61 to extend out of the channel 41 to make a mark on the workpiece 7.

[0038] The working principle of the vibration detection device of the utility model with a conical hole rotary body is as follows:

[0039] 1) Placing the workpiece 7: First, the workpiece 7 is brought into contact with the outer diameter line of the first truncated cone 111, and then, because the weight of the workpiece 7 overcomes the elastic force of the elastic member, the first truncated cone 11 is pressed downward until the workpiece 7 is brought into contact with the outer diameter line of the second truncated cone 121, and the workpiece 7 is placed;

[0040] 2) Runout detection: The lifting platform 5 drives the measuring mechanism 2 to rise and fall to achieve height adjustment. After it is in place, the measuring drive 22 drives the displacement sensor 21 to extend from the channel 41 and rests on the position of the workpiece 7 that needs to be detected. The rotating drive 3 drives the workpiece 7 to rotate through the detection platform assembly 1, and measures the runout value of the workpiece 7 through the change in the reading of the displacement sensor 21. According to the measurement data of the displacement sensor 21, the dotting drive 62 drives the dotting pen 61 to extend from the channel 41 to mark the workpiece 7. After the detection is completed, the measuring drive 22 drives the displacement sensor 21 to withdraw from the channel 41, and the dotting drive 62 drives the dotting pen 61 to withdraw from the channel 41.

Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
