Abstract
Description
Technical Field
[0001] The utility model relates to the field of non-destructive flaw detection, in particular to a feeding device of a magnetic particle flaw detector. Background Art
[0002] The magnetic particle detector is a non-destructive testing device used to detect surface and near-surface defects in metals. It uses the phenomenon that magnetic particles gather at defects under the action of a magnetic field. By observing and analyzing the distribution of magnetic particles, it can determine whether there are defects such as cracks, pores, and inclusions inside the inspected material.
[0003] Magnetic particle inspection machines are usually used to inspect the surface of steel pipes. Their workflow mainly includes the following steps: workpiece preparation, workpiece loading, parameter setting, magnetic powder spraying, magnetic field application, observation and evaluation, cleaning and recording, and demagnetization and unloading.
[0004] When loading workpieces into existing magnetic particle inspection machines, steel pipes are usually pushed into the machine. During use and observation, it was found that the steel pipes would shift during pushing, which would cause the position of the steel pipes to deviate during inspection, and thus lead to detection errors when the steel pipes were observed.
[0005] Therefore, in order to solve the above problems, a feeding device for a magnetic particle flaw detector is proposed. Utility Model Content
[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.
[0007] The technical solution adopted by the utility model to solve its technical problems is: the feeding device of a magnetic particle flaw detector described in the utility model comprises a support seat; the top of the support seat is fixedly connected to a slide rail; the middle of the slide rail is fixedly connected to a cylinder; the output end of the cylinder is fixedly connected to a slide plate; the slide plate and the slide rail are slidingly connected; the middle of the slide plate is symmetrically provided with a slide groove; the middle of the slide groove is slidingly connected to a orifice plate; the end of the orifice plate is fixedly connected to an elastic rod; the elastic rod and the slide groove are clearance fit; the top of the elastic rod is fixedly connected to a top plate; the bottom of the top plate is fixedly connected to a spring; the spring and the slide plate are both fixedly connected; after the steel pipe is placed on the surface of the slide plate, it will be clamped by the orifice plate and move with the slide plate, so as to realize the loading of the device during magnetic particle flaw detection of the steel pipe, improve the accuracy and convenience of the movement of the device during magnetic particle flaw detection of the steel pipe, and reduce the offset and shaking during the movement of the steel pipe.
[0008] Preferably, a sleeve is fixedly connected to the inner side wall of the slide groove; the sleeve is an L-shaped structure; the elastic rod and the sleeve are clearance-fitted; when the elastic rod moves along the slide groove, it will come into contact with the sleeve. Because the sleeve is an L-shaped structure, the sleeve will guide and support the elastic rod when it moves, reducing the shaking or deviation of the elastic rod when it moves, and also reducing the direct contact between the elastic rod and the slide groove, reducing the friction between the elastic rod and the slide groove.
[0009] Preferably, a plurality of first fixing plates are fixedly connected to the middle part of the elastic rod; a plurality of second fixing plates are fixedly connected to the inner side wall of the sleeve; the ends of the first fixing plate and the second fixing plate are correspondingly arranged; when the elastic rod moves along the sleeve, the first fixing plate will move together with the elastic rod, and the first fixing plate will pass through the second fixing plate and slide along the surface of the second fixing plate when moving; when the elastic rod has a tendency to reset under the elastic force of the spring, the first fixing plate will rub against the second fixing plate, causing the elastic rod to be subjected to additional friction, thereby improving the stability of the elastic rod during operation and further reducing the shaking and deviation of the elastic rod during operation.
[0010] Preferably, a plurality of protrusions are fixed to the end of one of the orifice plates; a plurality of grooves are opened at the end of the other orifice plate; the protrusions and grooves are correspondingly arranged and are slidably matched; when a pair of orifice plates approach each other, the protrusions will also move with the orifice plates and approach each other with the grooves. When a pair of orifice plates come into contact, the protrusions will enter the interior of the grooves, so that the orifice plates will be affected by the friction of the protrusions and the grooves, thereby enhancing the sealing of the connection between the pair of orifice plates, reducing the dislocation or offset that occurs when the orifice plates are connected, and enabling the orifice plates to fix the steel pipe more stably.
[0011] Preferably, a first magnet is fixed to the middle of the protrusion; a second magnet is fixed to the inner wall of the groove; when the distance between the protrusion and the groove is close to each other, the first magnet will also move with the protrusion, and the distance between the first magnet and the second magnet will change. When the first magnet and the second magnet are close to each other, the first magnet will be affected by the suction force of the second magnet, so that when the protrusion enters the groove, it will be affected by the magnetic force between the first magnet and the second magnet, further improving the stability of the orifice plate connection.
[0012] Preferably, the inner side wall of the skateboard is rotatably connected to a plurality of wheels; the wheels are arranged in an array; when the steel pipe is placed on the surface of the skateboard, it will come into contact with the wheels, and the wheels will support the steel pipe. When the staff observes the distribution of magnetic powder on the surface of the steel pipe, it needs to be rotated. When the steel pipe rotates, it will come into contact with the wheels and rotate under the action of friction. When the wheels rotate, the sliding friction between the steel pipe and the skateboard is converted into rolling friction, reducing the friction between the steel pipe and the skateboard, and also reducing the direct contact between the steel pipe and the top plate when it rotates, thereby improving the convenience of steel pipe rotation.
[0013] Preferably, a plurality of sponges are fixedly connected to the middle of the rotating wheel; the sponges are located at the top of the slide rail; before inspecting the steel pipe, the steel pipe can be rotated first so that the rotating wheel rotates with the steel pipe, and the sponges will rotate together when the rotating wheel rotates. When the sponges move, they will come into contact with the surface of the steel pipe and clean it, thereby reducing impurities attached to the surface of the steel pipe and realizing the cleaning of the steel pipe by the device before inspection.

[0025] Specific examples are given below.
[0026] See also Figures 1 to 5 As shown, a feeding device of a magnetic particle flaw detector described in an embodiment of the present invention includes a support seat 1; a slide rail 12 is fixedly connected to the top of the support seat 1; a cylinder 13 is fixedly connected to the middle of the slide rail 12; a slide plate 14 is fixedly connected to the output end of the cylinder 13; the slide plate 14 and the slide rail 12 are slidably connected; a slide groove 15 is symmetrically opened in the middle of the slide plate 14; a hole plate 16 is slidably connected to the middle of the slide groove 15; an elastic rod 17 is fixedly connected to the end of the hole plate 16; the elastic rod 17 and the slide groove 15 are clearance-fitted; the top of the elastic rod 17 is fixedly connected to a top plate 19; the bottom of the top plate 19 is fixedly connected to a spring 18; the spring 18 and the slide plate 14 are both fixedly connected; when working, a steel pipe is placed on the surface of the slide plate 14, the steel pipe will come into contact with and squeeze the top plate 19, and the top plate 19 will transmit pressure to the spring 18, The spring 18 will be in a compressed state under the action of pressure, and the elastic rod 17 and the top plate 19 will move along the slide 15 with the spring 18. When the elastic rod 17 moves, it will fit the inner wall of the slide 15 and bend. At the same time, when the elastic rod 17 moves, the orifice plate 16 will slide along the slide 15. At this time, the pair of orifice plates 16 will approach each other until they are in contact. When the pair of orifice plates 16 are in contact, the steel pipe will be fixed. Then the cylinder 13 can be started to make the slide plate 14 move with the steel pipe to the detection area. Finally, after the steel pipe is sprayed with magnetic powder and magnetized, the staff can rotate and observe the steel pipe; after the steel pipe is placed on the surface of the slide plate 14, it will be clamped by the orifice plate 16 and move with the slide plate 14, realizing the loading of the device during magnetic particle flaw detection of the steel pipe, improving the accuracy and convenience of the device's movement during magnetic particle flaw detection of the steel pipe, and reducing the offset and shaking during the movement of the steel pipe.
[0027] See also Figures 2 to 4As shown, the inner side wall of the slide groove 15 is fixedly connected with a sleeve 2; the sleeve 2 is an L-shaped structure; the elastic rod 17 and the sleeve 2 are clearance-fitted; when the elastic rod 17 moves along the slide groove 15, it will come into contact with the sleeve 2. Because the sleeve 2 is an L-shaped structure, the sleeve 2 will guide and support the elastic rod 17 when it moves, reducing the shaking or deviation of the elastic rod 17 when it moves, and also reducing the direct contact between the elastic rod 17 and the slide groove 15, reducing the friction between the elastic rod 17 and the slide groove 15.
[0028] See also Figure 4 As shown, a plurality of first fixing plates 3 are fixedly connected to the middle part of the elastic rod 17; a plurality of second fixing plates 32 are fixedly connected to the inner side wall of the sleeve 2; the ends of the first fixing plate 3 and the second fixing plate 32 are correspondingly arranged; when the elastic rod 17 moves along the sleeve 2, the first fixing plate 3 will move together with the elastic rod 17, and the first fixing plate 3 will pass through the second fixing plate 32 and slide along the surface of the second fixing plate 32 when moving. When the elastic rod 17 tends to reset under the elastic force of the spring 18, the first fixing plate 3 will rub against the second fixing plate 32, so that the elastic rod 17 is subjected to additional friction, thereby improving the stability of the elastic rod 17 during operation and further reducing the shaking and deviation of the elastic rod 17 during operation.
[0029] See also Figure 3 and Figure 5 As shown, a plurality of protrusions 4 are fixed to the end of one of the orifice plates 16; a plurality of grooves 42 are opened at the end of the other orifice plate 16; the protrusions 4 and the grooves 42 are correspondingly arranged and are slidably matched; when a pair of orifice plates 16 approach each other, the protrusions 4 will also move with the orifice plates 16 and approach each other with the grooves 42. When a pair of orifice plates 16 come into contact, the protrusions 4 will enter the interior of the grooves 42, so that the orifice plates 16 will be subject to the friction between the protrusions 4 and the grooves 42, thereby enhancing the sealing of the connection between the pair of orifice plates 16, reducing the dislocation or offset that occurs when the orifice plates 16 are connected, and enabling the orifice plates 16 to fix the steel pipe more stably.
[0030] See also Figure 3 and Figure 5 As shown, the middle part of the protrusion 4 is fixed with a first magnet 5; the inner wall of the groove 42 is fixed with a second magnet 52; when the distance between the protrusion 4 and the groove 42 is close to each other, the first magnet 5 will also move with the protrusion 4, and the distance between the first magnet 5 and the second magnet 52 will change. When the first magnet 5 and the second magnet 52 are close to each other, the first magnet 5 will be affected by the suction force of the second magnet 52, so that when the protrusion 4 enters the groove 42, it will be affected by the magnetic force between the first magnet 5 and the second magnet 52, further improving the stability of the orifice plate 16 when connected.
[0031] See also Figure 5 As shown, the inner wall of the slide 14 is rotatably connected to a plurality of wheels 6; the wheels 6 are arranged in an array; when the steel pipe is placed on the surface of the slide 14, it will come into contact with the wheels 6, and the wheels 6 will support the steel pipe. When the staff observes the distribution of magnetic powder on the surface of the steel pipe, it is necessary to rotate it. When the steel pipe rotates, it will come into contact with the wheels 6 and rotate under the action of friction. When the wheels 6 rotate, the sliding friction between the steel pipe and the slide 14 is converted into rolling friction, reducing the friction between the steel pipe and the slide 14, and also reducing the direct contact between the steel pipe and the top plate 19 when it rotates, thereby improving the convenience of steel pipe rotation.
[0032] See also Figure 5 As shown, a plurality of sponges 7 are fixedly connected to the middle of the rotating wheel 6; the sponges 7 are located at the top of the slide rail 12; before inspecting the steel pipe, the steel pipe can be rotated first so that the rotating wheel 6 rotates with the steel pipe, and the rotating wheel 6 rotates with the sponges 7, and the sponges 7 come into contact with the surface of the steel pipe when moving and clean it, thereby reducing impurities attached to the surface of the steel pipe and realizing the cleaning of the steel pipe before inspection by the device.
[0033] Working principle: Place the steel pipe on the surface of the slide 14, the steel pipe will come into contact with the top plate 19 and squeeze it, the top plate 19 will transfer the pressure to the spring 18, the spring 18 will be in a compressed state under the action of pressure, the elastic rod 17 and the top plate 19 will move along the slide 15 together with the spring 18, the elastic rod 17 will fit the inner wall of the slide 15 and bend when it moves, and at the same time, the elastic rod 17 will make the orifice plate 16 slide along the slide 15 when it moves. At this time, the pair of orifice plates 16 will approach each other until they come into contact. When the pair of orifice plates 16 come into contact, they will fix the steel pipe, and then the cylinder 13 can be started to make the slide 14 move with the steel pipe. When the elastic rod 17 moves along the chute 15, it will come into contact with the sleeve 2. Because the sleeve 2 is an L-shaped structure, the sleeve 2 will guide and support the elastic rod 17 when it moves. When the elastic rod 17 moves along the sleeve 2, the first fixed plate 3 will move with the elastic rod 17. When the first fixed plate 3 moves, it will pass through the second fixed plate 32 and slide along the surface of the second fixed plate 32. When the elastic rod 17 has a tendency to reset under the elastic force of the spring 18, the first fixed plate 3 will rub against the second fixed plate 32, causing the elastic rod 17 to return to its original position. The rod 17 is subjected to additional friction; when the pair of orifice plates 16 approach each other, the protrusion 4 will also move with the orifice plates 16 and approach each other with the groove 42. When the pair of orifice plates 16 come into contact, the protrusion 4 will enter the interior of the groove 42, so that the orifice plates 16 will be subjected to the friction of the protrusion 4 and the groove 42; when the distance between the protrusion 4 and the groove 42 is close to each other, the first magnet 5 will also move with the protrusion 4, and the distance between the first magnet 5 and the second magnet 52 will change. When the first magnet 5 and the second magnet 52 are close to each other, the first magnet 5 will be attracted by the second magnet 52, causing the protrusion 4 to enter the groove 42. When the steel pipe is placed on the surface of the slide 14, it will come into contact with the runner 6, and the runner 6 will support the steel pipe. When the staff observes the distribution of magnetic powder on the surface of the steel pipe, it needs to be rotated. When the steel pipe rotates, it will come into contact with the runner 6 and rotate under the action of friction. When the runner 6 rotates, the sliding friction between the steel pipe and the slide 14 is converted into rolling friction. Before testing the steel pipe, the steel pipe can be rotated first so that the runner 6 rotates with the steel pipe. When the runner 6 rotates, it will rotate with the sponge 7. When the sponge 7 moves, it will come into contact with the surface of the steel pipe and clean it.
