Description

Technical Field

[0001] This utility model relates to the field of ultrasonic water immersion flaw detection equipment, specifically to a water immersion ultrasonic clamping and rotating tooling for disc ring parts. Background Technology

[0002] The working principle of ultrasonic water immersion testing is based on the conductive properties of water and the characteristics of sound waves. The object to be tested is immersed in water, and an ultrasonic probe sends sound wave signals to the object, then receives the reflected signals. Changes in the signal can be used to determine whether defects or cracks exist in the object.

[0003] In traditional water immersion ultrasonic testing equipment, the fixtures used to clamp the workpieces generally require manual tightening of screws. When the workpiece wall thickness is small, uneven clamping force on different parts of the workpiece can easily occur, causing slight deformation of the workpiece. In addition, there are problems with low testing efficiency and low degree of automation. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a water-immersion ultrasonic clamping and rotating tooling for disc ring parts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model includes: a frame, on which a rotatable rotating seat is arranged; a rotating platform, which is arranged on the rotating seat and rotates synchronously with the rotating seat; and a centering clamping assembly, which is arranged on the rotating platform and rotates synchronously with the rotating seat, wherein the centering clamping assembly includes at least two sets of centering clamping units to clamp the disc ring in a manner that is away from or close to the central axis of the rotating platform.

[0006] In the preferred embodiment of the above-mentioned water-immersion ultrasonic clamping rotary tooling for disc ring parts, the centering clamping unit includes a driven screw rotatably mounted on the rotary table along the radial direction of the rotary table, a driven bevel gear mounted on the end of the driven screw, a slider threadedly connected to the driven screw, and a clamping block disposed on the slider.

[0007] In the preferred embodiment of the above-mentioned water-immersion ultrasonic clamping rotary tooling for disc ring parts, at least two of the driven bevel gears are driven by a centering drive structure. The centering drive structure includes at least a drive shaft rotatably configured in the middle of the rotary seat. The drive shaft has a drive bevel gear meshing with the driven bevel gear at its first end extending to the rotary table.

[0008] In the preferred technical solution of the above-mentioned water immersion ultrasonic clamping rotary tooling for disc ring parts, the rotary seat is an internal gear contact ball bearing, the bottom surface of the frame is equipped with a cover, the bottom of the frame is equipped with a first driving device inside the cover, and the rotating shaft end of the first driving device is equipped with a first drive gear that meshes with the rotary seat.

[0009] In the preferred embodiment of the above-mentioned water-immersion ultrasonic clamping rotary tooling for disc ring parts, a downwardly extending skirt is formed on the bottom surface of the periphery of the rotary table, and a sealing element is disposed between the skirt and the frame to seal the space between the bottom surface of the rotary table and the top surface of the frame.

[0010] In the preferred technical solution of the above-mentioned water immersion ultrasonic clamping and rotating tooling for disc ring parts, a second driving device is arranged at the bottom of the frame inside the cover, a second driving gear is arranged at the rotating shaft end of the second driving device, and a driven gear meshing with the second driving gear is arranged on the driving shaft.

[0011] In the preferred embodiment of the above-mentioned water-immersion ultrasonic clamping and rotating tooling for disc ring parts, a third driving device is arranged at the bottom of the frame inside the cover, and a third driving gear is arranged at the rotating shaft end of the third driving device to mesh with the driven gear.

[0012] In the preferred embodiment of the above-mentioned water-immersion ultrasonic clamping and rotating tooling for disc ring parts, the direction of the clamping block on the slider can be adjusted.

[0013] The beneficial effect of this utility model is that by simultaneously controlling at least two sets of centering clamping units to maintain the same displacement to clamp the disc ring, the clamped parts of the disc ring are subjected to uniform force, avoiding the problem of deformation of the tubular disc ring caused by different displacements of several centering clamping units. This allows this application to be adapted to tubular disc rings with smaller wall thickness, thus improving the applicability of this application. Attached Figure Description

Detailed Implementation

[0022] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "front," and "rear," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figures 1 to 7 As shown, the water-immersion ultrasonic clamping and rotating tooling for the disc ring component of this utility model includes: a frame 1, on which a rotatable rotating seat 2 is disposed; a rotating platform 3, which is disposed on the rotating seat 2 and rotates synchronously with the rotating seat 2; and a centering clamping assembly, which is disposed on the rotating platform 3 and rotates synchronously with the rotating seat 2. The centering clamping assembly includes at least two sets of centering clamping units 4 that clamp the disc ring component in a manner that is away from or close to the central axis of the rotating platform 3.

[0026] See Figure 1 The rotary table 3 and the rotary seat 2 are integrally rotated on the frame 1, and the centering clamping assembly is mounted on the rotary table 3. (See also...) Figure 1 , Figure 3The centering clamping assembly includes at least two sets of centering clamping units 4. The at least two sets of centering clamping units 4 are evenly distributed on the rotary table 3 with the central axis as the center. The at least two sets of centering clamping units 4 are positioned close to or away from the central axis of the rotary table 3 to loosen or clamp the inner ring of the tubular disc ring placed on the rotary table 3. This clamping method of the disc ring can effectively adapt to tubular components of different diameters and thicknesses, improve the detection range of different types of disc ring components, and control at least two sets of centering clamping units 4 to maintain the same displacement to clamp the disc ring component, so that the force on each clamped part of the disc ring component is uniform, avoiding the problem of deformation of the tubular disc ring component due to different displacements of several centering clamping units 4. This allows the application to adapt to tubular disc ring components with smaller wall thickness, thus improving the applicability of the application.

[0027] In one or more embodiments, the centering clamping unit 4 includes a driven screw 41 rotatably mounted on the rotary table 3 along the radial direction of the rotary table 3, a driven bevel gear 42 mounted on the end of the driven screw 41, a slider 43 threadedly connected to the driven screw 41, and a clamping block 44 disposed on the slider 43; at least two driven bevel gears 42 are driven by the centering drive structure 6, which includes at least a drive shaft 61 rotatably disposed in the middle of the rotary seat 2, and a drive bevel gear 62 meshing with the driven bevel gear 42 is mounted at one end of the drive shaft 61 that extends to the rotary table 3.

[0028] See Figures 1 to 5 The centering drive structure 6 includes at least a drive shaft 61 and a drive bevel gear 62 mounted on the end of the drive shaft 61. The drive shaft 61 is coaxial with the rotating disk. The centering clamping unit 4 includes a driven screw 41 rotatably mounted on the top of the rotating table 3, a driven bevel gear 42 disposed on the driven screw 41 at one end facing the central axis of the rotating table 3, a slider 43 threadedly connected to the driven screw 41, and a clamping block 44 mounted on the slider 43. The top end of the drive shaft 61 extends to the top of the rotating table 3 so that the drive bevel gear 62 and the driven bevel gear 42 can mesh.

[0029] Specifically, when clamping or releasing the disc ring component, the drive shaft 61 and the drive bevel gear 62 rotate synchronously. The driven screw 41 rotates on the rotary table 3 via the driven bevel gear 42 mounted at its end. This allows the slider 43, which is threadedly connected to the driven screw 41, to slide on the rotary table 3, moving away from or closer to the central axis of the rotary table 3. Consequently, the clamping block 44 can move away from or closer to the central axis of the rotary table 3 on the surface of the rotating head, thus clamping or releasing the inner wall of the tubular disc ring component placed on the surface of the rotary table 3. By utilizing the meshing connection between the drive bevel gear 62 and the driven bevel gear 42, and the threaded connection between the driven screw 41 and the slider 43, this application can control the movement of the slider 43 and the clamping block 44 while simultaneously achieving precise control of the position of the clamping block 44. This avoids the problem of deformation of the tubular disc ring component due to excessive movement of the clamping block 44, enabling this application to be adapted to tubular disc ring components with smaller wall thicknesses, thus improving its applicability and practicality.

[0030] In one or more embodiments, the rotating seat 2 is an internal tooth contact ball bearing, the bottom surface of the frame 1 is provided with a cover 7, the bottom of the frame 1 is provided with a first drive device 8 inside the cover 7, and the rotating shaft end of the first drive device 8 is equipped with a first drive gear 9 that meshes with the rotating seat 2.

[0031] See Figures 3 to 5 The rotating seat 2 is an internal tooth contact ball bearing. The internal tooth contact ball bearing has an inner ring and an outer ring that can rotate relative to each other, connected by rolling elements. The outer ring is fixed on the frame 1, and the inner ring has teeth on its inner side. The rotating table 3 is fixed on the inner ring and rotates synchronously with the inner ring.

[0032] See Figures 3 to 5 The first drive device 8 configured at the bottom of the frame 1 can be a drive motor. The rotating shaft end of the drive motor is equipped with a first drive gear 9, which meshes with the teeth of the inner ring. By driving the first drive gear 9 to rotate through the drive motor, the inner ring and the rotating table 3 can rotate synchronously, thereby enabling the disc ring component fixed on the rotating table 3 to rotate synchronously. This application utilizes the meshing of the first drive gear 9 with the teeth of the inner ring of the internal tooth contact ball bearing to drive the inner ring, rotating table 3, and disc ring component to rotate. This method can effectively ensure the rotational precision control of the disc ring component and has the characteristics of high transmission efficiency and smooth transmission. In addition, this application selects the rotating seat 2 as an internal tooth contact ball bearing, which can ensure that the rotating table 3 rotates more smoothly on the rotating seat 2, reduce the friction during the rotation of the rotating table 3, and reduce energy loss.

[0033] See Figure 3The cover 7 is installed at the bottom of the frame 1. The cover 7 can seal the first drive device 8, thereby ensuring the sealing of the first drive device 8 and ensuring that the first drive device 8 can be submerged in water to work.

[0034] In one or more embodiments, a second drive device 63 is disposed at the bottom of the frame 1 inside the cover 7, a second drive gear 64 is disposed at the rotating shaft end of the second drive device 63, and a driven gear 65 meshing with the second drive gear 64 is disposed on the drive shaft 61; a third drive device 66 is disposed at the bottom of the frame 1 inside the cover 7, and a third drive gear 67 meshing with the driven gear 65 is disposed at the rotating shaft end of the third drive device 66.

[0035] See Figure 3 , Figure 4 Both the second drive device 63 and the third drive device 66 can be drive motors. The second drive device 63 is an active drive motor, and the third drive device 66 is an auxiliary drive motor. The second drive gear 64 mounted on the rotating shaft end of the second drive device 63 and the third drive gear 67 mounted on the rotating shaft end of the third drive device 66 both mesh with the driven gear 65 mounted on the drive shaft 61. Both the second drive device 63 and the third drive device 66 are located within the space covered by the cover 7.

[0036] Specifically, when fixing the position of the disc ring component and controlling its rotation, the second drive device 63 first controls the second drive gear 64 to rotate, causing the driven gear 65 to drive the drive shaft 61 and the drive bevel gear 62 to rotate. The third drive device 66 controls the third drive gear 67 to rotate to assist the driven gear 65 in rotating. The drive bevel gear 62 can drive at least two driven bevel gears 42 meshing with it to rotate, so that the driven screw 41 drives the slider 43 and the clamping block 44 away from the central axis of the rotary table 3 while rotating, thereby clamping the disc ring component placed on the rotary table 3. After clamping the disc ring component, the first drive device 8 controls the first drive gear 9 to rotate, which drives the rotary seat 2 to rotate, so that the rotary table 3 and the clamped disc ring component on the rotary seat 2 can rotate with the rotary seat 2. This method has the characteristics of high clamping precision and high rotational accuracy of the disc ring component, and the overall structure is compact, with low space occupation and simple operation.

[0037] It should be noted that in order to ensure that the clamping degree of the clamping block 44 on the ring part remains unchanged when the rotating table 3 rotates, it is necessary to control the driven bevel gear 42 and the driving bevel gear 62 to rotate synchronously with the rotating table 3. That is, when the rotating table 3 and the ring part, the driven screw 41, and the driven bevel gear 42 arranged thereon are driven to rotate synchronously, the driving bevel gear 62 and the driving shaft 61 rotate synchronously with the rotating table 3, and the driven gear 65 rotates synchronously with the driving shaft 61. At this time, it is necessary for the second driving device 63 to control the second driving gear 64 and the third driving device 66 to control the third driving gear 67 to rotate to cooperate with the rotation of the driven gear 65 and the driving shaft 61, so as to ensure that when the rotating table 3 rotates, the driving bevel gear 62 and the driven bevel gear 42 can relatively remain stationary, and then ensure that when the rotating table 3 rotates, the position of the clamping block 44 remains unchanged, thus ensuring the clamping effect on the ring part.

[0038] In one or more embodiments, a skirt 31 extending downward is formed on the bottom surface of the circumferential side of the rotating table 3, and a seal 10 for sealing the space between the bottom surface of the rotating table 3 and the top surface of the frame 1 is arranged between the skirt 31 and the frame 1.

[0039] See Figure 3 、 Figure 6 、 Figure 7 The rotating seat 2 is an internal gear type contact ball bearing, and the internal gear type contact ball bearing has an inner ring and an outer ring that are rotatably connected to each other; in order to seal the working space formed by the upper part of the frame 1, the inner part of the inner ring, and the bottom surface part of the rotating table ३ to protect the normal operation of several gear sets, in this application, the bottom surface of the circumferential side of the rotating table 3 is extended downward to the upper part of the frame 1 to form a skirt 31, and a seal 10 is arranged between the inner wall of the skirt 31 and the frame 1 to make the above working space in a sealed state.

[0040] See Figure 3 、 Figure 6 、 Figure 7 The seal 10 can be a metal spring piece and a rubber cushion layer coated on the surface of the metal spring piece. The shape of the metal spring piece can be "凵" or "冂", or a shape formed by the combination of "凵" and "冂" in the vertical direction. It should be noted that the upper and lower ends of the metal spring piece on the side far from the axis of the rotating table 3 always abut against the inner wall of the skirt 31 of the rotating table 3. The metal spring piece on the side far from the axis of the rotating table 3 is generally in a ")" structure. Through this setting, it can be ensured that the upper and lower ends of the metal spring piece on the side far from the axis of the rotating table 3 always have a tendency to abut against the skirt 31, thereby ensuring the sealing effect on the above working space.

[0041] In one or more embodiments, the direction of the clamping block 44 on the slider 43 can be adjusted.

[0042] See Figure 2 , Figure 3 The clamping block 44 includes a base and a pressing part. The base has a cam structure and is bolted to the slider 43. The pressing part is located on the base and is relatively far away from the slider 43. When it is necessary to lock the disc ring with a smaller inner diameter, the pressing part can be installed on the side close to the central axis of the rotary table 3. When it is necessary to lock the disc ring with a larger inner diameter, the pressing part can be installed on the side away from the central axis of the rotary table 3. At the same time, it can be combined with several centering clamping units 4 to lock disc rings of different diameters, further improving the detection range of disc ring types in this application.

[0043] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
