[0001] This utility model relates to the field of nondestructive testing technology, specifically a nondestructive testing device with a positioning mechanism. Background Technology

[0002] Non-destructive testing (NDT) refers to a method of inspecting and testing the internal structure, state, and type, quantity, and shape of defects in mechanical materials without damaging or affecting their performance or internal structure. This is done by utilizing changes in thermal, acoustic, optical, electrical, and magnetic reactions caused by abnormalities or defects in the material's internal structure, using physical or chemical methods and modern technology and equipment.

[0003] In the prior art, such as the non-destructive testing device for steel with a positioning mechanism proposed in patent application number "CN202321375300.9", this utility model can clamp and position steel of different specifications, avoid the steel from shaking during the testing process, ensure the accuracy of non-destructive testing of steel, and at the same time, can perform non-destructive testing on different positions of steel, which greatly improves the testing efficiency.

[0004] However, in the aforementioned patent application, steel of different specifications can be positioned before inspection. However, after the steel surface is inspected, it cannot be automatically flipped over. It still requires manual flipping and non-destructive testing of the reverse side of the steel. The operation is relatively troublesome and affects the efficiency of non-destructive testing of steel. Utility Model Content

[0005] The purpose of this invention is to provide a non-destructive testing device with a positioning mechanism to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A non-destructive testing device with a positioning mechanism includes a testing table and a support. Connecting shafts are rotatably connected to both inner sidewalls of the testing table. A frame is movably installed inside the testing table, and one end of each of the two connecting shafts is fixedly connected to the frame. A limit mechanism is provided inside the frame. A turntable is rotatably connected to the top of the support via a shaft. A testing instrument body is mounted on the bottom surface of the turntable, and a probe is mounted on the bottom of the testing instrument body. A horizontal groove is formed on the back of the testing table, and a reciprocating screw is rotatably connected inside the groove. A movable block is sleeved on the outside of the reciprocating screw, and one end of the movable block is fixedly connected to the support. A groove is formed on the outer sidewall of the frame, and a trigger mechanism is provided inside the groove. A switch button is installed at the top of the groove.

[0008] The limiting mechanism includes two clamping plates and two double-ended threaded screws. The two clamping plates are movably installed inside the frame, and the two double-ended threaded screws are rotatably connected inside the frame near the two sides. The triggering mechanism includes a triangular block and a contact plate, both of which are movably installed inside the groove.

[0009] Preferably, each of the two double-ended threaded screws is fitted with a movable block one near both ends, and one end of the movable block one is fixedly connected to the clamping plate.

[0010] Preferably, the outer wall of the clamping plate has a plurality of insertion holes, and a clamping head is inserted into each of the plurality of insertion holes. A support spring is installed between one end of the clamping head and the inner wall of the insertion hole.

[0011] Two motors are installed on the outer wall of the frame, and the output ends of the two motors are respectively connected to one end of two double-ended threaded screws.

[0012] Preferably, gears are fixedly connected to the outer walls of both connecting shafts, support frames are installed on both outer walls of the testing platform, and electric telescopic rods are installed at the bottom of the inner sides of both support frames.

[0013] Preferably, each of the two electric telescopic rods has a rack fixedly connected to its upper end, and the two racks are respectively meshed with two gears. The output end of the switch button is electrically connected to the input end of the two electric telescopic rods.

[0014] Preferably, one end of the touch plate is slidably connected to the triangular block, and two telescopic push rods are installed on the inner sidewall of the groove, with one end of each of the two telescopic push rods being fixedly connected to the triangular block.

[0015] Both of the two telescopic push rods are fitted with a return spring. Two telescopic push rods are installed at the top of the groove, and the bottom ends of both telescopic push rods are fixedly connected to the contact plate. Both telescopic push rods are fitted with a return spring.

[0016] Preferably, a second motor is installed on the outer wall of the testing platform, and the output end of the second motor is connected to one end of a reciprocating lead screw. A third motor is installed on the upper surface of the bracket, and the output end of the third motor is connected to the turntable.

[0017] The beneficial effects of this utility model are:

[0018] 1. In this utility model, after the upper surface of the steel is inspected, the support continues to move, causing one end of the contact plate to move relative to the inclined plane of the triangular block. The contact plate moves vertically upward, pressing the switch button to activate the two electric telescopic rods. With the help of two gears, the frame is rotated 180° to flip the steel. Through the reciprocating screw and the second movable block, the support and the probe head move in opposite directions to the main body of the detector, and the flipped steel is inspected. Thus, after the upper surface of the steel is inspected, it is automatically flipped to inspect the reverse side of the steel, making the steel inspection more comprehensive and eliminating the need for manual flipping, effectively improving the efficiency of non-destructive testing of steel.

[0019] 2. In this utility model, two motors simultaneously drive two double-ended threaded screws to rotate. In conjunction with each movable block, the two clamping plates can be moved closer to each other, so that each clamping head contacts the outer wall of the steel. Each clamping head can move into the insertion hole according to the shape of the steel, causing the support spring to be compressed and contracted. Under the action of the rebound force of the support spring, the clamping head that has moved into the insertion hole can be moved outward, squeezing the steel. This can effectively clamp and fix steel of different shapes, effectively improving the applicability of the non-destructive testing device. Moreover, the main body of the testing instrument and the probe can move along a circular trajectory and move laterally as a whole, which can perform all-round testing of the steel to be tested.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] A non-destructive testing device with a positioning mechanism, such as Figures 1-7 As shown, the device includes a testing platform 1 and a support 5. Connecting shafts 3 are rotatably connected to both inner walls of the testing platform 1. A frame 2 is movably installed inside the testing platform 1, and one end of each of the two connecting shafts 3 is fixedly connected to the frame 2. A limit mechanism is installed inside the frame 2. A turntable 6 is rotatably connected to the top of the support 5 via a shaft. A detector body 7 is mounted on the bottom surface of the turntable 6, and a probe head 22 is mounted on the bottom of the detector body 7. A transverse groove is opened on the back of the testing platform 1, and a reciprocating screw 17 is rotatably connected inside the groove. A movable block 1 is sleeved on the outside of the reciprocating screw 17. 6. One end of the movable block 16 is fixedly connected to the bracket 5. The outer wall of the frame 2 has a groove 13. A triggering mechanism is set inside the groove 13. A switch button 19 is installed at the top of the groove 13. The limiting mechanism includes two clamping plates 8 and two double-ended threaded rods 9. The two clamping plates 8 are movably installed inside the frame 2. The two double-ended threaded rods 9 are rotatably connected inside the frame 2 near the sides. The triggering mechanism includes a triangular block 14 and a contact plate 15. The triangular block 14 and the contact plate 15 are movably installed inside the groove 13.

[0032] Two double-ended threaded screws 9 are fitted with movable blocks 10 near both ends on their outer surfaces. One end of each movable block 10 is fixedly connected to the clamping plate 8. The threads on the outer walls of the double-ended threaded screws 9 are in opposite directions near both ends. The inner wall of the movable block 10 where it engages with the double-ended threaded screw 9 is provided with threads that match the threads on the double-ended threaded screw 9. When the double-ended threaded screw 9 rotates, the movable block 10 can be moved by the engagement of the threads.

[0033] The outer wall of the clamping plate 8 has several insertion holes, and each insertion hole has a clamping head 11 inserted inside. A support spring is installed between one end of the clamping head 11 and the inner wall of the insertion hole. Two motors are installed on the outer wall of the frame 2, and the output ends of the two motors are respectively connected to one end of two double-ended threaded screws 9. Motor 2 is installed on the outer wall of the testing table 1, and the output end of motor 2 is connected to one end of the reciprocating screw 17. Motor 3 is installed on the upper surface of the bracket 5, and the output end of motor 3 is connected to the turntable 6. The inner wall of the joint between the movable block 2 16 and the reciprocating screw 17 has a thread that matches the reciprocating screw 17. When the reciprocating screw 17 rotates, it can drive the movable block 2 16 to move laterally in the transverse groove under the cooperation of the thread. The models of motors 1, 2 and 3 are all PG42-775.

[0034] In use, the steel to be tested is placed inside the frame 2 and positioned between the two clamping plates 8. Then, two motors simultaneously drive two double-ended threaded screws 9 to rotate, causing each movable block 10 to move along the double-ended threaded screws 9. This causes the two clamping plates 8 to move closer to each other, so that each clamping head 11 contacts the outer wall of the steel. Along the shape of the outer wall of the steel, the corresponding clamping heads 11 that are in contact with the steel are squeezed and retracted into the insertion hole. The length of the clamping head 11 moving into the insertion hole is determined by the shape of the steel, which causes the support spring to be squeezed and retracted. Under the action of the rebound force of the support spring, the clamping heads 11 that have moved into the insertion hole can be moved outward to squeeze the steel. This allows for good clamping and positioning of steel of different shapes, effectively improving the applicability of the non-destructive testing device.

[0035] After the steel to be inspected is fixed, the reciprocating screw 17 is rotated by motor 2, which in turn moves the movable block 16 along the transverse groove, causing the support 5 to move. The main body 7 of the detector and the probe 22 follow the support 5 to move above the steel and probe along the top of the steel for non-destructive testing. At the same time, the turntable 6 is rotated by motor 3, which can move the main body 7 of the detector and the probe 22 along a circular trajectory, so that any position on the steel can be inspected, realizing comprehensive inspection of the upper surface of the steel. The probe 22 emits ultrasonic pulses, which propagate inside the steel and are reflected when they encounter defects or interfaces between different materials. The detector body 7 analyzes the pulses to determine the location and size of defects in the steel, thus completing the non-destructive testing of the steel. Other existing technologies are not described in detail here.

[0036] Gears 4 are fixedly connected to the outer walls of both connecting shafts 3. Support frames 23 are installed on both outer walls of the testing table 1. Electric telescopic rods 12 are installed at the bottom of both support frames 23. Racks 18 are fixedly connected to the upper ends of both electric telescopic rods 12, and the two racks 18 are respectively meshed with the two gears 4. The output end of the switch button 19 is electrically connected to the input end of the two electric telescopic rods 12. The electrical connection can be through wires, which is existing technology and will not be described in detail. The model of the electric telescopic rod 12 is YNS-07-B or any other model with the same function.

[0037] One end of the contact plate 15 is slidably connected to the triangular block 14. Two telescopic push rods 20 are installed on the inner side wall of the groove 13, and one end of each telescopic push rod 20 is fixedly connected to the triangular block 14. A return spring is sleeved on the outside of each telescopic push rod 20. Two telescopic push rods 21 are installed at the top inside the groove 13, and the bottom ends of each telescopic push rod 21 are fixedly connected to the contact plate 15. A return spring is sleeved on the outside of each telescopic push rod 21. When the triangular block 14 moves, the telescopic push rods 20 and the return springs 1 are pulled and extended accordingly. The telescopic push rods 20 limit the movement of the triangular block 14, so that the triangular block 14 can only move laterally. Similarly, the telescopic push rods 21 limit the contact plate 15 to move only vertically. As the contact plate 15 moves, the telescopic push rods 21 and the return springs 2 are compressed and shortened accordingly. Subsequently, under the action of the rebound force of the return springs 1 and 2, the triangular block 14 and the contact plate 15 can be reset and restored to their initial state.

[0038] Specifically, after the inspection of the upper surface of the steel is completed, the bracket 5 continues to move, contacts the triangular block 14, and pushes the triangular block 14 to move laterally along the inside of the groove 13, so that one end of the contact plate 15 moves relative to the inclined surface of the triangular block 14, causing the contact plate 15 to move vertically upward, triggering the switch button 19, activating the two electric telescopic rods 12, causing the moving ends of the two electric telescopic rods 12 to drive the two racks 18 to move upward, thereby driving the two gears 4 to rotate 180°, causing the frame 2 to rotate 180°, flipping the steel. At this time, the reciprocating screw 17 works in the same way. The second movable block 16 can drive the bracket 5 to move in the opposite direction to inspect the flipped steel. This allows for automatic flipping after the upper surface of the steel is inspected, enabling more comprehensive steel inspection without manual flipping and effectively improving the efficiency of non-destructive testing. Subsequently, triggering the switch button 19 will cause the electric telescopic rod 12 to move the rack 18 down to the initial position, allowing the next piece of steel to be inspected to be flipped. By repeating the above operation, the flipping operation can be performed continuously on each piece of steel to be inspected.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
