Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaw detection equipment technology, specifically to a ring flaw detection centering and rotating device. Background Technology
[0002] A ring is a form of product in the forging industry. It is a ring-shaped object exposed to external forces in a metal component and undergoes plastic deformation to become an object subject to appropriate compressive forces. Due to various factors during the ring rolling process, the rolled ring products may develop various types of defects. Therefore, the quality of the rings needs to be inspected before they are put into production.
[0003] Existing flaw detection equipment for rings uses two main methods: one involves moving an ultrasonic probe to contact the surface of the ring to detect internal damage, but this method has a large blind zone, low efficiency, and cannot detect the ring clamping area; the other method involves rotating the ring using a worktable, but the center position of the ring is prone to shift during rotation, making it impossible to simultaneously ensure the ring's centering and rotation, resulting in inaccurate flaw detection results.
[0004] Chinese patent CN206832750U discloses an automatic flaw detection device for annular forgings, including a rotary drive device and a detection device. The rotary drive device includes a limiting roller and drive shafts respectively disposed on both sides of the limiting roller. The limiting roller abuts against the inner surface of the annular forging, and the drive shafts abut against the outer surface of the annular forging and drive it to rotate. The detection device includes a bracket, on which a first moving probe and a second moving probe are disposed. The first moving probe moves along a first direction, and the second moving probe moves along a second direction. The first direction is perpendicular to the second direction and parallel to the axial direction of the annular forging. The first and second moving probes are connected to an ultrasonic flaw detector. The advantage of this invention is that during the detection process, the workpiece is detected through the cooperation of the drive shaft and the limiting roller. After each rotation of the probe, it moves horizontally until the entire detection area is covered, achieving flaw detection of the entire annular forging. However, due to its structural limitations, it can only detect flaws on the outer wall and top surface of the annular forging, but it cannot effectively detect flaws on the inner wall and bottom surface. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a ring component flaw detection centering and rotating device that can achieve centering and rotation of the ring component during flaw detection, and can adjust, clamp and support ring components of different sizes to achieve all-round flaw detection of the ring component.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0007] A ring component flaw detection centering rotary device includes a base, on which a rotating support mechanism is uniformly distributed in a circle along the center of the base, and a centering clamping mechanism for clamping the ring component is slidably mounted on the rotating support mechanism; a gearbox is also provided at the center of the base to drive the centering clamping mechanism to move centripetally to clamp the ring component, and the gearbox is connected to a drive motor; a flaw detection adjustment component for flaw detection at different positions on the surface of the ring component is also provided on the base, and the flaw detection adjustment component is offset from the rotating support mechanism.
[0008] The aforementioned ring component flaw detection centering rotary device includes a rotary support mechanism comprising a mounting plate radially disposed on a base, bearing seats disposed at both ends of the mounting plate, and a support roller for supporting the ring component installed between the bearing seats; one end of the support roller away from the center of the base is connected to a rotary motor.
[0009] The aforementioned ring flaw detection centering and rotating device includes a centering and clamping mechanism comprising a sliding plate slidably mounted on a mounting plate, a top clamping wheel mounted on the top of the sliding plate that abuts against the side wall of the ring and clamps the ring; the bottom of the sliding plate is threadedly connected to a lead screw mounted on the mounting plate via a lead screw nut, and the radial end of the lead screw is connected to the output shaft of the gearbox.
[0010] In the aforementioned ring component flaw detection centering rotary device, the lead screw is installed between two bearing seats and positioned below the support roller.
[0011] In the aforementioned ring component flaw detection centering rotary device, a driven bevel gear is provided on the output shaft inside the gearbox, the motor shaft of the drive motor is connected to the driving bevel gear, and the driven bevel gear meshes with the driving bevel gear for transmission.
[0012] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0013] This invention provides a ring component flaw detection centering and rotating device with a simple structure and convenient operation. It uses a support roller to support the ring component and utilizes the friction between the roller and the ring component to rotate it, thereby adjusting the circumferential position of the ring component for inspection at different locations. Furthermore, by incorporating a radially movable centering and clamping mechanism, it achieves both clamping and centering of the ring component. This device not only provides stable support for the ring component, ensuring smooth rotation, but also simultaneously achieves centering and clamping, making it suitable for flaw detection of ring components of different sizes.
[0014] Because the flaw detection adjustment component and the rotating support mechanism are misaligned, the bottom surface of the ring will be exposed during the rotation of the ring. By adjusting the position of the flaw detection equipment to the bottom of the ring, the flaw detection of the bottom surface of the ring can be completed. Therefore, this utility model realizes comprehensive flaw detection of different positions of the ring surface by adjusting the position of the flaw detection equipment, thus improving the flaw detection efficiency.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] A rotating device for centering and inspecting flawed components, such as Figures 1 to 4 As shown, the device includes a base 1, on which a rotating support mechanism is evenly distributed in a circle along the center of the base 1. A centering clamping mechanism for clamping the ring 12 is slidably mounted on the rotating support mechanism. A gearbox 9 is also mounted at the center of the base 1 to drive the centering clamping mechanism to move centripetally and clamp the ring 12. The gearbox 9 is connected to a drive motor 10. A flaw detection adjustment assembly 11 for flaw detection on the surface of the ring 12 at different positions is also mounted on the base 1. The flaw detection adjustment assembly 11 is offset from the rotating support mechanism.
[0022] In this embodiment, there are three rotating support mechanisms, and adjacent rotating support mechanisms are spaced 120° apart.
[0023] The rotating support mechanism includes a mounting plate 2 radially arranged on the base 1. Bearing seats 3 are respectively provided at both ends of the mounting plate 2. A support roller 4 for supporting the ring 12 is installed between the bearing seats 3. One end of the support roller 4 away from the center of the base 1 is connected to a rotary motor 5 to drive the support roller 4 to rotate. The friction between the support roller and the ring is used to drive the ring to rotate so as to perform flaw detection at different positions of the ring.
[0024] The centering clamping mechanism includes a sliding plate 7 slidably mounted on the mounting plate 2. A clamping wheel 8 is mounted on the top of the sliding plate 7, which abuts against the side wall of the ring 12 and clamps the ring 12. The clamping wheel 8 is connected to the clamping wheel shaft on the sliding plate 7 through a bearing.
[0025] The bottom of the sliding plate 7 is threadedly connected to the lead screw 6 installed on the mounting plate 2 via a lead screw nut seat. The lead screw 6 is installed between two bearing seats 3 and is located below the support roller 4. In this utility model, the lead screw can be a ball screw or a T-type lead screw, etc.
[0026] The mounting plate 2 is equipped with guide rails on both sides to guide the sliding plate 7, ensuring the stability of the sliding plate's operation.
[0027] The radial end of the lead screw 6 is connected to the output shaft of the gearbox 9. A driven bevel gear is provided on the output shaft inside the gearbox 9. The motor shaft of the drive motor is connected to the driving bevel gear. The driven bevel gear meshes with the driving bevel gear, thereby driving the output shaft of the gearbox to rotate.
[0028] The gearbox 9 drives the lead screw 6 to rotate, converting the rotational motion of the lead screw into the centripetal linear motion of the lead screw nut and the sliding plate 7, thereby causing the clamping wheel to abut against the side wall of the ring and clamp the ring. At the same time, multiple clamping wheels at different angles cooperate to center the ring.
[0029] In this embodiment, there are two clamping wheels 8, which are arranged symmetrically about the center of the mounting base 2.
[0030] In actual operation, the clamping wheel 8 can clamp either the inner wall or the outer wall of the ring 12. Figure 3 The center clamping wheel 8 clamps the ring 12 by abutting against the outer wall of the ring 12. Figure 4 The center clamping wheel 8 clamps the ring by abutting against the inner wall of the ring.
[0031] The flaw detection adjustment assembly 11 can adjust the position of the flaw detection equipment. Since the flaw detection adjustment assembly and the rotating support mechanism are misaligned, the bottom surface of the ring will be exposed during the rotation of the ring. Therefore, the flaw detection adjustment assembly can perform comprehensive flaw detection on the inner side, outer side, top surface and bottom surface of the ring.
[0032] In this embodiment, there are two flaw detection adjustment components 11. In other embodiments, to ensure the number of flaw detections, multiple flaw detection adjustment components 11 can be evenly arranged along the circumferential direction.
[0033] In this embodiment, the flaw detection adjustment component 11 is a three-axis adjustment module. Of course, in this utility model, the flaw detection adjustment component 11 can also be a two-axis module.
[0034] Specifically, the flaw detection adjustment assembly 11 includes a first radial slide rail disposed on the base 1, a centripetal adjustment slider slidably disposed on the first radial slide rail, a vertical slide rail mounted on the centripetal adjustment slider, a vertical adjustment slider slidably disposed on the vertical slide rail, a second radial slide rail mounted on the vertical adjustment slider, and a flaw detection device slidably disposed on the second radial slide rail.
[0035] The horizontal position of the flaw detector is adjusted by the first radial slide rail, the height position is adjusted by the vertical slide rail, and the horizontal position is readjusted by the second radial slide rail. This allows the flaw detector to be moved to the inner side, outer side, bottom surface, and top surface of the ring for flaw detection. The operation is simple and can be flexibly adjusted as needed.
[0036] The operating steps and principle of this utility model are as follows:
[0037] First, place the ring 12 on the support roller 4 so that the support roller 4 can support the bottom of the ring. Then, start the drive motor 10 so that the sliding plate 7 drives the top tightening wheel 8 to move towards the center. When all the top tightening wheels 8 abut against the outer wall of the ring, the ring will automatically center under the tightening action of the top tightening wheels 8.
[0038] Next, the rotary motor 5 is started. The rotary motor 5 drives the support roller to rotate, which in turn drives the ring to rotate, so that the flaw detection equipment can perform flaw detection on different positions of the ring.
[0039] During the flaw detection process, the position of the flaw detection equipment can be adjusted by the flaw detection adjustment component 11, so that the flaw detection equipment can perform multi-directional flaw detection on the inner wall, outer wall, top surface and bottom surface of the ring, and the error of each ring can be corrected by the color recognition sensor.
[0040] This invention provides a ring component flaw detection centering and rotating device with a simple structure and convenient operation. It uses a support roller to support the ring component and utilizes the friction between the roller and the ring component to rotate it, thereby adjusting the circumferential position of the ring component for inspection at different locations. Furthermore, by incorporating a radially movable centering and clamping mechanism, it achieves both clamping and centering of the ring component. This device not only provides stable support for the ring component, ensuring smooth rotation, but also simultaneously achieves centering and clamping, making it suitable for flaw detection of ring components of different sizes.
[0041] Because the flaw detection adjustment component and the rotating support mechanism are misaligned, the bottom surface of the ring will be exposed during the rotation of the ring. By adjusting the position of the flaw detection equipment to the bottom of the ring, the flaw detection of the bottom surface of the ring can be completed. Therefore, this utility model realizes comprehensive flaw detection of different positions of the ring surface by adjusting the position of the flaw detection equipment, thus improving the flaw detection efficiency.
