[0074] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0076] The first aspect of the present invention provides a high-precision ultrasonic automatic detection device, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, it is used to detect the ring forgings placed vertically in batches in the forging factory, and there are gaps between adjacent ring forgings. The equipment includes:

[0077] A first telescopic cylinder 3 and an adjusting portion for adjusting the position of the first telescopic cylinder 3 in the forging plant;

[0078] A connecting frame 13 fixed to the output shaft of the first telescopic cylinder 3 and a fixing column 14 fixedly connected to one end of the connecting frame 13, wherein the fixing column 14 is arranged horizontally, and the width of the gap is greater than the height of the fixing column 14;

[0079] At least one detection mechanism provided on the fixed column 14, the detection mechanism comprising:

[0080] An inner ring 24 is sleeved on the outer surface of the fixing column 14, and an outer ring groove 25 is provided on the outer side surface of the inner ring 24;

[0081] A sliding portion for driving the inner ring 24 to slide on the outer surface of the fixed column 14;

[0082] The inner side surface is provided with an outer ring 26 of a convex ring, the outer ring 26 is sleeved on the outer side surface of the inner ring 24, and the convex ring is rotatably connected with the outer ring groove 25;

[0083] A plurality of side rods 27 distributed around the central axis of the outer ring 26 and an ultrasonic phased array probe 30 connected to the side rods 27, wherein the bottom ends of the side rods 27 are fixed to the outer side surface of the outer ring 26;

[0084] A rotating part for driving the outer ring 26 to rotate;

[0085] The planes where the two end surfaces of the fixed column 14 are located constitute a contraction area. The inner ring 24 has at least a first position and a second position on the fixed column 14. When the inner ring 24 is in the first position, the ultrasonic phased array probe 30 is located in the contraction area. When the inner ring 24 is in the second position, the ultrasonic phased array probe 30 is located outside the contraction area.

[0086] When placing a ring forging, for example, with a diameter of about 1m, the following can be used: Figure 1 The ring forgings are placed in a vertical stacking manner as shown, and there is a certain width of gap between adjacent ring forgings to facilitate the staff to take and other operations. After the ring forgings are put into storage, the ring forgings in the warehouse will not be taken out of the warehouse for a considerable period of time. Therefore, it is possible to conduct non-destructive testing after the ring forgings are put into storage. If batch non-destructive testing can be carried out after the ring forgings are put into storage, the production efficiency of the ring forgings can be greatly improved. Accordingly, this application realizes non-destructive testing of the ring forgings after they are put into storage. The specific process is described in the following paragraph.

[0087] In this embodiment, when the annular forgings are stacked vertically, it is best to arrange them in a rectangular array, which can facilitate the detection of this equipment. The detection process is as follows:

[0088] Step 1: Apply coupling agent on the side of the ring forging;

[0089] Step 2: Use the adjustment part to adjust the fixing column 14 to be just above one of the gaps;

[0090] Step 3: Drive the fixed column 14 to move into the gap by the first telescopic cylinder 3 so that the central axis of the fixed column 14 coincides with the central axis of the annular forging to be inspected;

[0091] Step 4: The position of the inner ring 24 is adjusted by the sliding part so that the inner ring 24 moves from the first position to the second position, and the ultrasonic phased array probe 30 contacts the side of the annular forging. At this time, the ultrasonic phased array probe 30 can detect the annular forging. During the detection process, the rotating part drives the outer ring 26 to rotate, so that the ultrasonic phased array probe 30 detects multiple positions of the annular forging.

[0092] Since the gap is formed by two vertically stacked annular forgings, the above process can be used to complete the inspection of one of the annular forgings corresponding to the gap. After the inspection is completed, the inner ring 24 is moved from the second position to the first position through the sliding part. At this time, the ultrasonic phased array probe 30 is retracted to the contraction area again, and then the fixed column 14 and the inspection mechanism are separated from the gap through the first telescopic cylinder 3. Then the above inspection process can be repeated, so that the inspection mechanism inspects the adjacent gaps, thereby completing the inspection of all the annular forgings in turn. Through the present invention, after the annular forgings are produced, they are directly put into storage, and the vertically stacked annular forgings can be non-destructively inspected in turn in the warehouse of the forging factory. Therefore, the production time of the annular forgings occupied by non-destructive inspection can be saved, and the production efficiency can be effectively improved.

[0093] As an implementation method, Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the adjustment unit includes:

[0094] Side beams 8 are parallel to each other, the side beams 8 are arranged inside the forging plant, and side grooves 9 are arranged on opposite sides of the side beams 8;

[0095] A cross beam 1 is located between the side beams 8, the ends of the cross beam 1 are slidably connected with the corresponding side grooves 9, and a beam groove 2 is provided on the side surface of the cross beam 1;

[0096] A first motor 6 is provided on the side beam 8 and a screw rod 12 having one end fixedly connected to the output shaft of the first motor 6, one end surface of the side beam 8 is provided with a rotating hole communicating with the side groove 9, the screw rod 12 is rotatably connected to the rotating hole, the screw rod 12 is threadedly connected to the screw hole 10 provided on the cross beam 1, and the other end of the screw rod 12 is rotatably connected to the end of the side groove 9;

[0097] A connecting block 4 is arranged on the side of the first telescopic cylinder 3, and a bottom plate 5 is arranged at the bottom of the connecting block 4, and the bottom plate 5 is slidably connected with the beam groove 2;

[0098] The second motor 11 is arranged on the connecting block 4 and the main gear 7 is installed on the output shaft of the second motor 11 . The main gear 7 is meshed with a first spur rack arranged on the side surface of the beam 1 .

[0099] In this embodiment, the adjustment part is arranged in the warehouse of the forging factory and is located above the placed annular forgings. When adjusting the position of the fixed column 14, the first motor 6 drives the screw 12 to rotate to drive the overall movement of the beam 1, and the second motor 11 drives the main gear 7 to rotate, thereby driving the first telescopic cylinder 3 to move on the beam 1, thereby realizing the adjustment of the position of the fixed column 14, so that the fixed column 14 can move to any gap position.

[0100] In addition, as an implementation method, Figure 2 , Figure 6 , Figure 7 As shown, two detection mechanisms are provided and are symmetrically arranged on the fixing column 14 .

[0101] In this embodiment, the vertical stacking method is preferably as follows Figure 1 As shown, the batch of annular forgings presents a rectangular array effect, and the central axes of the annular forgings in each column are collinear, so as to ensure that the gaps formed in each column of the annular forgings will not be misaligned. Under the above conditions, through two detection mechanisms, after entering a gap, the two annular forgings corresponding to the gap can be detected. Therefore, here, it is assumed that there are 7 gaps in one column, namely the first gap, the second gap, the third gap, the fourth gap, the fifth gap, the sixth gap and the seventh gap. After the first gap is detected, the second gap can be skipped and the third gap can be directly entered for measurement. After the measurement of the third gap is completed, the fourth gap is skipped and the fifth gap is directly entered for measurement. After the measurement of the fifth gap is completed, the sixth gap is skipped and the seventh gap is directly entered for measurement. The detection efficiency can be effectively improved.

[0102] Here, a structure of a sliding part is introduced, such as Figure 2 , Figure 6 , Figure 7 , Fig.10 , Fig.12 As shown, the sliding part includes:

[0103] A second telescopic cylinder 16 is disposed at one end of the fixed column 14. An adjusting chamber 17 is disposed inside the fixed column 14. The output shaft of the second telescopic cylinder 16 extends into the adjusting chamber 17.

[0104] A connecting rod 22 with one end fixed to the inner side of the inner ring 24, the connecting rod 22 is slidably connected to a surface groove 23 provided on the side surface of the fixing column 14, and in different detection mechanisms, the opposite surface grooves 23 are connected through a connecting hole 55 provided in the fixing column 14, and an extension plate extending into the connecting hole 55 is provided on one side of the connecting rod 22;

[0105] An intermediate gear 51 is disposed in the communicating hole 55. The intermediate gear 51 is located between two extension plates. A second spur rack is disposed on the surface of the extension plate. The intermediate gear 51 meshes with the second spur rack.

[0106] The adjusting frame 18 is located in the adjusting chamber 17 , and the adjusting frame 18 is fixedly connected to the output shaft of the second telescopic cylinder 16 , and the adjusting frame 18 is fixedly connected to all the connecting rods 22 in one of the detection mechanisms.

[0107] In this embodiment, when the inner ring 24 needs to be moved from the first position to the second position, the output shaft of the second telescopic cylinder 16 is contracted, and the connecting rod 22 connected to the adjustment frame 18 will move to the outside of the contraction area. At the same time, through the intermediate gear 51, the connecting rod 22 on the other side drives the corresponding inner ring 24 to move to the outside of the contraction area. When the inner ring 24 moves to the second position and the ultrasonic phased array probe 30 contacts the side of the annular forging, the ultrasonic phased array probe 30 can detect the annular forging, and the second telescopic cylinder 16 maintains the output shaft state at this time. When the detection is completed, the output shaft of the second telescopic cylinder 16 extends outward, so that the inner ring 24 moves to the first position, and the ultrasonic phased array probe 30 is located in the contraction area.

[0108] Considering that the difference between the inner diameter and the outer diameter of some specifications of annular forgings is large, the ultrasonic phased array probe 30 has a small detection range after contacting one position on the side of the annular forging. Therefore, as an embodiment, Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the testing organization also includes:

[0109] A telescopic rod 29 whose top end is fixedly connected to the ultrasonic phased array probe 30, a telescopic hole 28 is provided inside the side rod 27, the telescopic hole 28 penetrates the top end surface of the side rod 27, the telescopic rod 29 is slidably connected to the telescopic hole 28, and the top end of the telescopic rod 29 extends to the outside of the telescopic hole 28;

[0110] The device further comprises a driving unit for driving the telescopic rod 29 to slide along the telescopic hole 28 .

[0111] In this embodiment, after the ultrasonic phased array probe 30 contacts a certain position on the side of the annular forging, detection can be performed. Since there are several ultrasonic phased array probes 30 and multiple contact positions at the same time, a circular ring composed of multiple first contact positions is an initial contact ring. When the rotating part drives the outer ring 26 to rotate, the ultrasonic phased array probe 30 can be used to detect multiple positions of the initial contact ring. After completing the detection of the initial contact ring, the driving part drives the telescopic rod 29 to slide along the telescopic hole 28, so that the ultrasonic phased array probe 30 can move above or below the initial contact ring. After the ultrasonic phased array probe 30 moves to the next contact position, the driving part stops driving. At this time, the circular ring composed of the positions contacted by each ultrasonic phased array probe 30 is a subsequent contact ring. The ultrasonic phased array probe 30 detects each contact position in the subsequent contact ring. The accuracy of the detection result is ensured by detecting multiple positions.

[0119] A driving gear 21 mounted on the rotating shaft 19, the driving gear 21 corresponds to the driving ring 45;

[0120] A plurality of planetary gears 42 are disposed around the driving gear 21, the planetary gears 42 mesh with the driving gear 21, a wheel groove 41 is provided between the surface ring groove 44 and the shaft cavity 20, the planetary gears 42 are disposed in the wheel groove 41, and the planetary gears 42 mesh with a gear ring 43 disposed on the inner side of the driving ring 45;

[0121] The fixing member is used to fix the outer ring 26 when the inner ring 24 is located at the first position, and the fixing member is separated from the outer ring 26 when the inner ring 24 is located at the second position.

[0122] In this embodiment, when the inner ring 24 is located at the second position, the ultrasonic phased array probe 30 contacts the side of the annular forging. It can be seen from the introduction of the previous embodiment that the contact position is located in the initial contact ring. The ultrasonic phased array probe 30 can detect multiple positions of the initial contact position through the driving of the rotating part. When the ultrasonic phased array probe 30 needs to be adjusted to the next subsequent contact ring, it is first necessary to move the inner ring 24 to the first position through the sliding part. At this time, the fixing member fixes the outer ring 26, and then the third motor 15 is started, and the third motor 15 is driven by the driving gear 21 and Each corresponding planetary gear 42 causes the driving ring 45 to rotate. When the driving ring 45 rotates, the linkage ring 34 is driven to rotate through the driving rod 33. During the rotation of the linkage ring 34, due to the meshing of the first thread and the second thread, the telescopic rod 29 slides in the telescopic hole 28 to achieve the purpose of changing the position of the ultrasonic phased array probe 30. After the position of the ultrasonic phased array probe 30 is directly opposite to the position of the subsequent contact ring, the sliding part drives the inner ring 24 to move to the second position again, which is the separation of the fixing part from the outer ring 26. In this way, the rotating part can normally drive the outer ring 26 to rotate. In addition, here, since the position of the inner ring 24 is variable, when the position of the inner ring 24 changes, the inner slider 37 slides in the inner wall groove 36 to ensure that after the inner ring 24 moves to the first position, the driving rod 33 can normally drive the linkage ring 34.

[0123] The fixings here, such as Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 As shown, the fixing member is a positioning rod 53 arranged on the outer side of the fixing column 14, a positioning end is provided at the top of the positioning rod 53, and a positioning hole 54 matching the positioning end is provided on the outer side of the outer ring 26. When the inner ring 24 is in the first position, the positioning end is located in the positioning hole 54.

[0124] In this embodiment, when the inner ring 24 is in the first position, the positioning end is located in the positioning hole 54, so the outer ring 26 can be fixed to prevent the outer ring 26 from rotating when the driving unit in the previous embodiment drives the telescopic cylinder to slide. When the inner ring 24 is in the second position, the positioning end is separated from the positioning hole 54, and the rotating unit can normally drive the outer ring 26 to rotate. Before the inner ring 24 moves from the second position to the first position, the position of the outer ring 26 is adjusted by the rotating unit so that the positioning end is facing one of the positioning holes 54, so as to ensure that the positioning end enters the positioning hole 54 after the inner ring 24 moves to the first position.

[0125] As an implementation method, Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 As shown, the rotating part includes:

[0126] A linkage rod 48 is fixed at one end to the side rod 27, and a ring slot 50 is provided on the side surface of the driving ring 45, and the front end of the linkage ring 34 is rotatably connected to the ring slot 50;

[0127] A linkage plate 49 is arranged at the front end of the linkage rod 48 , and a linkage groove 52 is arranged on the inner wall of the inserting ring groove 50 . When the inner ring 24 is located at the second position, the linkage plate 49 is located in the linkage groove 52 .

[0128] In this embodiment, when the inner ring 24 is located in the first position, the linkage plate 49 is located in the insert ring groove 50 and is separated from the linkage groove 52. At this time, after the third motor 15 is started, the driving rod 33 can achieve the purpose of driving the telescopic rod 29. After the telescopic rod 29 drives the ultrasonic phased array probe 30 to move to a certain position, at this time, the linkage plate 49 is facing one of the linkage grooves 52. In this way, when the inner ring 24 moves to the second position, the linkage plate 49 just enters the linkage groove 52. In this way, when the third motor 15 causes the driving ring 45 to rotate, the outer ring 26 can be driven to rotate through the linkage rod 48.

[0129] As an implementation method, Figure 2 , Figure 6 , Figure 7 , Fig.16 As shown, the device also includes:

[0130] An extension column 59 connecting the ultrasonic phased array probe 30 and the telescopic rod 29;

[0131] A sealing cover 57 is provided with a plug hole 58, and an extension column 59 is sealed and slidably connected to the plug hole 58;

[0132] A spring 56 sleeved on the extension column 59, one end of the spring 56 is fixed to the telescopic rod 29, and the other end of the spring 56 is fixed to the sealing cover 57;

[0133] An inlet 60 is arranged on the sealing cover 57, and the inlet 60 is connected to the water outlet of the water pump through a hose. The water inlet of the water pump is connected to the water reservoir. An air outlet connected to the inside of the sealing cover 57 is also arranged near the inlet 60, and a solenoid valve for controlling the opening and closing of the air outlet is arranged on the air outlet.

[0134] In this embodiment, a sealing ring is further provided at the opening of the sealing cover 57. When the sealing cover 57 contacts the side of the annular forging, a sealed space will be formed in the sealing cover 57. The elastic force of the spring 56 can improve the sealing effect after the sealing space is formed in the sealing cover 57. After the sealed space is formed, the water pump is started to pump water into the sealing cover 57. At this time, the solenoid valve is opened to discharge the gas in the sealing cover 57. When the sealing cover 57 is filled with water, the solenoid valve is closed, and the water in the sealing cover 57 is used as a coupling agent.

[0135] In addition, here, the first telescopic cylinder 3 and the second telescopic cylinder 16 can be air cylinders, hydraulic cylinders or electric telescopic cylinders.
