Abstract
Description
Technical fields:
[0001] This invention relates to the field of production technology of ring testing equipment, and in particular to a ring rotating mechanism. Background technology:
[0002] For larger diameter raceways, there are currently two main methods. One is probe movement, where the probe is moved around the raceway's circular surface. However, during this movement, the probe is easily affected by external vibrations, causing slight vibrations that affect the raceway's flaw detection results. The other method is to rotate the raceway. However, due to its weight, it is difficult to rotate the raceway manually during inspection. To address this, devices that automatically rotate raceways have emerged on the market. However, when these devices rotate the raceway, most of the power is applied to the side of the raceway. This power needs to be tightly pressed against the side of the raceway to rotate it. However, the side of the raceway is prone to slippage, especially when the external force is too strong. Once slippage occurs on the side of the raceway during rotation, the center position of the raceway can easily shift, leading to deviations in the flaw detection results. Summary of the Invention:
[0003] The purpose of this invention is to provide a rotating mechanism for a ring, which solves one or more of the problems of the prior art mentioned above.
[0004] To solve the above-mentioned technical problems, the present invention provides a rotating mechanism for a ring, the structure of which includes a ring inspection station and three bases. The three bases are distributed in a circle on the outside of the inspection station. The innovation lies in that the structure also includes a slider that can slide freely on the base and three drive boxes fixed on the base. The sliding direction of the three sliders on the three bases is close to or away from the center of the inspection station. The three drive boxes are all located away from the inspection station. Each drive box is provided with a sliding drive component that drives the slider to slide on the base. The sliding drive component is provided with a fixed plate connected to the slider. One of the fixed plates is provided with a movable plate that can move elastically. The elastic movement direction of the movable plate is close to or away from the center of the inspection station. Support blocks are fixed on the other two fixed plates. Each movable plate and the two support blocks is provided with an L-shaped clamping rotating component. The long side of the clamping rotating component is provided with a rotatable roller. The rotation surface of the roller is parallel to the horizontal plane. The short side of the clamping rotating component is provided with a rotatable bushing. The rotation surface of the bushing is perpendicular to the horizontal plane. Rotation drive components that drive the roller to rotate are provided between the support blocks and the drive boxes.
[0005] Furthermore, the aforementioned sliding drive component includes a drive nut, a lead screw, and a first rotary motor mounted on a fixed plate. The interior of the drive housing is divided into a rotary drive area and a sliding drive area. The first rotary motor is fixed to the top of the drive housing and its output end extends into the sliding drive area. A connecting block is provided at the end of the base, and a first rotating hole is provided at the bottom of the connecting block. One end of the lead screw is rotatably mounted on the first rotating hole, and the rod body of the lead screw is threadedly connected to the drive nut. The other end of the lead screw extends into the interior of the sliding drive area and is provided with a first connecting gear. The output end of the first rotary motor is provided with a first drive gear, and the first drive gear is meshed with the first connecting gear.
[0006] Furthermore, one of the fixed plates has a slide rail on its surface, with one end of the slide rail extending toward the center of the inspection station. The other end of the slide rail has a spring seat fixed to the fixed plate. The bottom of the movable plate has a sliding block that slides on the slide rail. The spring seat has several buffer springs that extend parallel to the slide rail and are fixedly connected to the end of the movable plate.
[0007] The support block includes a left support block and a right support block. Both the left and right support blocks are fixed vertically upwards on the surfaces of two other fixed plates. The right support block is set close to the inspection station, and the distance between the left and right support blocks corresponds to the length of the roller.
[0008] Furthermore, the clamping rotating component includes a first side plate and a second side plate. The first side plate is vertically fixed to one end of the movable plate or the top of the right support block, and the second side plate is vertically fixed to the other end of the movable plate or the top of the left support block. The height of the second side plate is higher than the height of the first side plate. The bushing is rotatably disposed on the top of the second side plate, and the roller is rotatably disposed between the bottom of the second side plate and the first side plate.
[0009] Furthermore, the aforementioned rotary drive component includes a second rotary motor and a rotating rod. The second rotary motor is fixed to the top of the drive box and its output end extends into the rotary drive area. The top of the two connecting blocks is provided with a second rotating hole. One end of the rotating rod is rotatably connected to the inside of the second rotating hole. The rod body rotatably passes through the first side plate and the second side plate in sequence. A second drive gear is provided at the connection between the rotating rod and the second side plate. A second connecting gear is provided at the end of the roller. The second drive gear and the second connecting gear are meshed together. A third drive gear is provided at the output end of the second rotary motor. The other end of the rotating rod extends into the inside of the rotary drive area and is provided with a third connecting gear. The third connecting gear and the third drive gear are meshed together.
[0010] The beneficial effects of this invention are as follows:
[0011] 1. This invention provides a rotating mechanism for a ferrule. The ferrule to be inspected is placed at the inspection station, with its bottom supported on three rollers. A sliding drive is then activated, causing a fixed plate to move towards the center of the inspection station. The slider's design ensures stable movement of the fixed plate. As the fixed plate moves, the side of the ferrule gradually abuts against the three bushings, thus clamping the ferrule tightly between the three rotating clamping components. The elastic movement of the movable plate prevents the side of the ferrule from being rigidly pressed between two bushings, allowing the ferrule to adaptively clamp between the three rotating clamping components. Then, the rotary drive is activated, which drives the two rollers to rotate, thereby causing the ring to rotate on the three rollers. At this time, the three bushings are synchronously and tightly attached to the side of the ring and rotate with the ring. During the rotation of the ring, the force of the rotation of the two rollers comes from the bottom of the ring and drives the rotation of the ring. The bushings only limit the rotation position of the ring and do not need to be pressed tightly on the side of the ring. This can prevent the side of the ring from slipping on the bushings and ensure that the ring always stays in the same center position during the rotation, thus ensuring the stability of the ring detection.
[0012] 2. This invention provides a rotating mechanism for a collar. When the three bushings clamp the side of the collar, they need to be kept at the same height. When the collar is placed on the three rollers, the three rollers also need to be kept on the same horizontal plane to ensure that the clamping of the collar can be kept stable. Therefore, one bushing and one roller are set on the movable plate, and their height is affected by the stacking effect of the sliding block and the movable plate. Therefore, when the bushings and rollers are set on the other two fixed plates, the left support block and the right support block are used to counteract the stacking height of the sliding block and the movable plate, thereby ensuring that the height of the three bushings and the three rollers can be kept consistent.
[0013] 3. The present invention provides a rotating mechanism for a ferrule. The clamping rotating component is set in an L-shape by a first side plate and a second side plate. The roller connects the bottom of the second side plate and the first side plate. The bushing is rotatably fixed to the top of the second side plate, so that the bushing, the second side plate, the roller and the first side plate form an L-shape. The L-shaped setting of the clamping rotating component can fit against the side of the ferrule, thereby ensuring that the clamping and fixing of the ferrule among the three clamping rotating components can remain stable.
[0014] 4. This invention provides a rotating mechanism for a ring. The connecting block can be used for both the rotating end connected to one end of the lead screw and the rotating end connected to one end of the rotating rod. Meanwhile, the other end of the lead screw and the other end of the rotating rod are connected to the first rotary motor and the second rotary motor respectively inside the drive box 2. The two are separated by the sliding drive area and the rotary drive area respectively, thereby avoiding mutual interference at the connection point of the two inside the drive box, ensuring the independence of the rotation of the lead screw and the rotation of the rotating rod, and thus optimizing the connection structure of the lead screw and the rotating rod.

[0022] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.
[0023] like Figures 1 to 2In one specific embodiment of the present invention, the structure includes a ring inspection station 101 and three bases 100, which are arranged in a circle on the outer side of the inspection station 101. The structure also includes sliders 1 that can slide freely on the bases 100 and three drive boxes 2 fixed to the bases 100. The sliding directions of the three sliders 1 on the three bases 100 are all close to or away from the center of the inspection station 101. The three drive boxes 2 are all located away from the inspection station 101. Each drive box 2 is provided with a sliding drive component 3 that drives the sliders 1 to slide on the bases 100. The sliding drive component 3 is connected to the slider 1. The fixed plate 102 has a movable plate 4 that can move elastically. The movable plate 4 moves elastically towards or away from the center of the detection station 101. Support blocks 5 are fixed on the other two fixed plates 102. L-shaped clamping rotating parts 6 are provided on the movable plate 4 and the two support blocks 5. The long side of the clamping rotating part 6 is provided with a rotatable roller 103. The rotating surface of the roller 103 is parallel to the horizontal plane. The short side of the clamping rotating part 6 is provided with a rotatable bushing 104. The rotating surface of the bushing 104 is perpendicular to the horizontal plane. Rotary driving parts 7 for driving the roller 103 to rotate are provided between the support blocks 5 and the drive box 2.
[0024] In this invention, the working principle of rotation during ring inspection is as follows: The ring to be inspected is placed at the inspection station 101, with the bottom of the ring supported on three rollers 103. Then, the sliding drive 3 is activated, driving the fixed plate 102 to move towards the center of the inspection station 101. The slider 1 is set to ensure that the movement of the fixed plate 102 remains stable. As the fixed plate 102 moves, the side of the ring gradually abuts against the three bushings 104, thereby clamping the ring tightly between the three clamping rotating parts 6. The elastic movement of the movable plate 4 prevents the side of the ring from being rigidly pressed between two bushings 104, allowing the ring to adaptively clamp between the three clamps. Between the rotating parts 6, the rotating drive 7 is then turned on. The rotating drive 7 drives the two rollers 103 to rotate, thereby causing the ring to rotate on the three rollers 103. At this time, the three bushings 104 are synchronously and tightly attached to the side of the ring and rotate with the ring. During the rotation of the ring, the rotational force of the two rollers 103 comes from the bottom of the ring and drives the rotation of the ring. The bushings 104 only limit the rotation position of the ring and do not need to be pressed tightly on the side of the ring. This can prevent the side of the ring from slipping on the bushings 104 and ensure that the ring always stays in the same center position during the rotation, thus ensuring the stability of the ring detection.
[0025] In this invention, as a preferred embodiment, the sliding drive component 3 includes a drive nut 31, a lead screw 32, and a first rotary motor 33 disposed on the fixed plate 102. The interior of the drive box 2 is divided into a rotary drive area 21 and a sliding drive area 22. The first rotary motor 33 is fixed to the top of the drive box 2 and its output end extends to the sliding drive area 22. The end of the base 100 is provided with a connecting block 8, and the bottom of the connecting block 8 is provided with a first rotating hole 81. One end of the lead screw 32 is rotatably disposed on the first rotating hole 81. The rod body of the lead screw 32 is threadedly connected to the drive nut 31. The other end of the lead screw 32 extends into the interior of the sliding drive area 22 and is provided with a first connecting gear 321. The output end of the first rotary motor 33 is provided with a first drive gear 331, and the first drive gear 331 is meshed with the first connecting gear 321.
[0026] In this invention, the working principle of the sliding drive component 3 is as follows: the movement of the fixed plate 102 on the base 100 is powered by the first rotary motor 33. Under the meshing action of the first drive gear 331 and the first connecting gear 321, the meshing position of the two is in the sliding drive area 22, thereby driving the lead screw 32 to rotate on the first rotating hole 81. The rotation of the lead screw 32 acts on the drive nut 31, thereby driving the fixed plate 102 to move. The movement of the fixed plate 102 drives the slider 1 to slide on the base 100, thereby ensuring the stability of the movement of the fixed plate 102 on the base 100.
[0027] In this invention, as a preferred embodiment, a slide rail 105 is provided on the surface of one of the fixed plates 102. The extension direction of one end of the slide rail 105 is toward the center of the detection station 101. The other end of the slide rail 105 is provided with a spring seat 9 fixed on the fixed plate 102. A sliding block 41 is provided at the bottom of the movable plate 4. The sliding block 41 is slidably disposed on the slide rail 105. A plurality of buffer springs 91 are provided on the spring seat 9. The extension direction of the buffer springs 91 is parallel to the slide rail 105 and is fixedly connected to the end of the movable plate 4.
[0028] The support block 5 includes a left support block 51 and a right support block 52. Both the left support block 51 and the right support block 52 are fixed vertically upward on the surfaces of the other two fixed plates 102. The right support block 52 is set close to the detection station 101. The distance between the left support block 51 and the right support block 52 corresponds to the length of the roller 103.
[0029] In this invention, the process of the elastic movement of the movable plate 4 is as follows: When the bushing 104 on the movable plate 4 abuts against the side of the collar, the bushing 104 is subjected to the reaction force of the side of the collar. The bushing 104 is pushed by the collar and moves away from the detection station 101, thereby driving the movable plate 4 to move away from the detection station 101 on the fixed plate 102. The setting of the sliding block 41 and the slide rail 105 ensures the stability of the movement of the movable plate 4, while the buffer spring 91 can play an elastic buffering role on the movement of the movable plate 4, thereby ensuring that the bushing 104 can always abut against the side of the collar, so that the collar can be adaptively clamped between the three bushings 104. This can ensure the stability of the collar being clamped by the three bushings 104, and also avoid the phenomenon of the collar being rigidly clamped by the three bushings 104 and being damaged by clamping.
[0030] In this invention, when the three bushings 104 clamp the sides of the collar, they need to be kept at the same height, and when the collar is placed on the three rollers 103, the three rollers 103 also need to be kept on the same horizontal plane to ensure that the clamping of the collar can be kept stable. Therefore, one bushing 104 and one roller 103 are set on the movable plate 4, and their height is affected by the stacking effect of the sliding block 41 and the movable plate 4. Therefore, when the bushings 104 and rollers 103 are set on the other two fixed plates 102, the left support block 51 and the right support block 52 are used to counteract the stacking height of the sliding block 41 and the movable plate 4, thereby ensuring that the heights of the three bushings 104 and the three rollers 103 can be kept consistent.
[0031] In this invention, as a preferred embodiment, the clamping rotating member 6 includes a first side plate 61 and a second side plate 62. The first side plate 61 is vertically fixed to one end of the movable plate 4 or the top of the right support block 52, and the second side plate 62 is vertically fixed to the other end of the movable plate 4 or the top of the left support block 51. The height of the second side plate 62 is higher than the height of the first side plate 61. The bushing 104 is rotatably disposed on the top of the second side plate 62, and the roller 103 is rotatably disposed between the bottom of the second side plate 62 and the first side plate 61.
[0032] In this invention, the clamping rotating member 6 is set in an L-shape by the first side plate 61 and the second side plate 62. The roller 103 connects the bottom of the second side plate 62 and the first side plate 61. The bushing 104 is rotatably fixed to the top of the second side plate 62, so that the bushing 104, the second side plate 62, the roller 103 and the first side plate 61 form an L-shape. The L-shaped setting of the clamping rotating member 6 can fit against the side of the ring, thereby ensuring that the clamping and fixing of the ring among the three clamping rotating members 6 can remain stable.
[0033] In this invention, as a preferred embodiment, the aforementioned rotary drive component 7 includes a second rotary motor 71 and a rotating rod 72. The second rotary motor 71 is fixed to the top of the drive box 2 and its output end extends to the rotary drive area 21. The tops of the two connecting blocks 8 are provided with second rotating holes 82. One end of the rotating rod 72 is rotatably connected to the inside of the second rotating hole 82. The rod body of the rotating rod 72 rotatably passes through the first side plate 61 and the second side plate 62 in sequence. A second drive gear 621 is provided at the connection between the rotating rod 72 and the second side plate 62. A second connecting gear 622 is provided at the end of the roller 103. The second drive gear 621 and the second connecting gear 622 are meshed together. The output end of the second rotary motor 71 is provided with a third drive gear 711. The other end of the rotating rod 72 extends into the inside of the rotary drive area 21 and is provided with a third connecting gear 721. The third connecting gear 721 and the third drive gear 711 are meshed together.
[0034] In this invention, the working principle of the rotary drive 7 is as follows: the rotation of the drum 103 is powered by the second rotary motor 71. Under the meshing action of the third drive gear 711 and the third connecting gear 721, the meshing position of the two is in the rotary drive area 21, thereby driving the rotating rod 72 to rotate on the second rotating hole 82. The rotation of the rotating rod 72, under the meshing action of the second connecting gear 622 and the second drive gear 621, drives the drum 103 to rotate.
[0035] In this invention, the connecting block 8 can be used for both the rotating end connected to one end of the lead screw 32 and the rotating end connected to one end of the rotating rod 72. Meanwhile, the other end of the lead screw 32 and the other end of the rotating rod 72 are connected to the first rotary motor 33 and the second rotary motor 71 respectively inside the drive box 2. The two are separated by the sliding drive area 22 and the rotary drive area 21 respectively, thereby avoiding mutual interference at the connection point of the two inside the drive box 2. This ensures the independence of the rotation of the lead screw 32 and the rotation of the rotating rod 72, thus optimizing the connection structure of the lead screw 32 and the rotating rod 72.
