Description

Technical Field

[0001] The present invention belongs to the technical field of magnetic particle flaw detection devices, and specifically refers to a jig for the flow operation of magnetic particle flaw detection of pick teeth. Background Art

[0002] A pick tooth is a rotary tooth-shaped tool used for excavating soil or rock, usually made of high-hardness and expensive steel. Since pick teeth bear large stresses and loads for a long time, flaw detection on the surface and inside of pick teeth is an important part of inspection and maintenance work.

[0003] Magnetic particle flaw detection is a common detection method for fine scratches on the surface or near the surface of metal parts; when a workpiece is magnetized, if there are defects on the surface of the workpiece, due to the increased magnetic resistance at the defect, magnetic leakage occurs, forming a local magnetic field, and magnetic powder accumulates here to show the shape and position of the defect, thereby judging the existence of the defect.

[0004] Magnetic particle flaw detection is a relatively mature non-destructive testing method, but its operation is currently mostly completed manually. Not only is the efficiency low, but uneven spraying of magnetic powder will also affect the judgment of the size of the scratches; moreover, since the rotary parts need to be detected all around, if an automated flow jig is designed in the factory, a full-circle magnetic suspension liquid spraying device and a scanning detection device are mostly required to achieve surface detection of the parts. Summary of the Invention

[0005] In view of the above situation, to overcome the defects of the prior art, the present invention proposes a jig for the flow operation of magnetic particle flaw detection of pick teeth; due to the heavy weight of the pick teeth to be tested, multi-point clamping on the same plane can limit its horizontal position and longitudinal height, but cannot limit its inclination and swing deviating from the vertical axis; and if clamping on two planes is set, the structure will be relatively complex. Based on multi-point clamping on the same plane, the present invention utilizes the characteristic that an attractive force will be generated between the pick teeth to be tested after magnetization and an iron ring to adjust the central axis of the pick teeth to be tested; at the same time, the lifting ejector pin used for magnetization, which needs to contact the pick teeth to be tested, is also used to limit the bottom central position of the pick teeth to be tested; without adding a clamping mechanism on the second plane, stable clamping of the pick teeth to be tested is also achieved.

[0006] In addition, the present invention also uses a fork for controlling the lifting of the pick teeth to be tested to push the pre-tightening rack synchronously, and without distinguishing the diameter specifications of the pick teeth to be tested, it can achieve the technical effects of automatically synchronously clamping when installing the pick teeth to be tested and automatically synchronously releasing when disassembling the pick teeth to be tested.

[0007] The technical solution adopted by the present invention is as follows: The present invention provides a magnetic particle flaw detection flow operation tooling for picks, including an adaptive clamping mechanism, a lifting mechanism, a direction adjustment and holding mechanism, and a transmission mechanism. The adaptive clamping mechanism is arranged on a reciprocating conveying component, the lifting mechanism is arranged on the adaptive clamping mechanism, and the direction adjustment and holding mechanism is arranged on the adaptive clamping mechanism.

[0008] Further, the adaptive clamping mechanism includes a clamping sliding component, an elastic clamping component, an arc-shaped clamping component, and a self-rotation driving component. The clamping sliding component is arranged on the reciprocating conveying component, the elastic clamping component is arranged on the clamping sliding component, the arc-shaped clamping component is arranged on the clamping sliding component, and the self-rotation driving component is arranged on the arc-shaped clamping component.

[0009] Through the adaptive clamping mechanism, without setting an independent lifting control module, by using the driving of the clamping driving component on the clamping device, the height adjustment of the pick to be tested can be realized simultaneously, thereby improving the clamping stability; compared with the traditional technical solution, the structure and operation steps are simplified.

[0010] Preferably, the clamping sliding component includes a bottom plate, a guide rail, a slider, and a sliding plate. The bottom plate is arranged on the reciprocating conveying component, the guide rail is arranged on the bottom plate, the slider is engaged and slidably arranged on the guide rail, the sliding plate is arranged on the slider, and the sliding plates are symmetrically arranged.

[0011] As a further preference of the present invention, the elastic clamping component includes a rack guiding bracket, a pre-tightening rack, a spring bracket, and a rack pre-tightening spring. The rack guiding bracket is fixedly connected to the sliding plate, the pre-tightening rack is engaged and slidably arranged in the rack guiding bracket, the spring bracket is arranged on the bottom plate, and the rack pre-tightening spring is arranged between the pre-tightening rack and the spring bracket.

[0012] By sliding the two sliding plates, the gap size for clamping the pick to be tested can be changed, so as to automatically adapt to the diameter size of the handle part of picks with different specifications; by providing a pre-tightening force through the rack pre-tightening spring, it can automatically adapt to picks with different specifications, thereby achieving the technical effect of automatically clamping picks with unknown diameters without setting sensors.

[0013] Preferably, the arc-shaped clamping component includes a fork, a main rotating shaft, an arc-shaped bracket, and a clamping wheel. The fork is arranged on the sliding plate, the main rotating shaft is rotatably arranged in the fork, the arc-shaped bracket is fixedly connected to the main rotating shaft, the clamping wheel is rotatably arranged on the arc-shaped bracket, and the outer contours of the arc-shaped bracket and the clamping wheel are continuous arcs.

[0014] Through the overall swing of the arc-shaped clamping assembly, the lifting of the to-be-tested pick can be controlled, thereby completing the longitudinal position adjustment of the to-be-tested pick. This can not only install the to-be-tested pick to a position convenient for the magnetic ring but also improve the firmness of clamping.

[0015] As a further preference of the present invention, the self-rotation drive assembly includes a winding wheel, a rotating pull rope, and a winding spring. The winding wheel is fixedly connected to the clamping wheel at the top. The rotating pull rope is wound around the winding wheel. The end of the rotating pull rope is arranged on the external frame. The winding spring is arranged between the winding wheel and the arc-shaped bracket.

[0016] When the adaptive clamping mechanism moves as a whole, through the release of the rotating pull rope, the winding wheel can drive a clamping wheel connected thereto to rotate, and at the same time, the winding spring accumulates elastic potential energy. When resetting, the winding wheel will rewind the rotating pull rope under the elastic force of the winding spring.

[0017] Furthermore, the lifting mechanism includes a clamping drive assembly and a transmission assembly. The clamping drive assembly is arranged on the bottom plate, and the transmission assembly is rotatably arranged on the arc-shaped clamping assembly.

[0018] Preferably, the clamping drive assembly includes a drive motor, a drive gear, and a gear shaft. The drive motor is arranged on the bottom plate. The drive gear is arranged on the output shaft of the drive motor. The gear shaft is rotatably arranged on the fork. The gear shaft and the drive gear are meshed and transmitted.

[0019] As a further preference of the present invention, the transmission assembly includes a clamping gear and a transmission gear. The clamping gear is fixedly connected to the main rotating shaft. The clamping gear and the gear shaft are meshed and transmitted. The transmission gear is fixedly connected to one end of the main rotating shaft. The transmission gear and the pre-tightening rack are meshed and transmitted.

[0020] Through the transmission of the gear shaft, on the one hand, the swing of the arc-shaped clamping assembly can be controlled, and on the other hand, the compression amount of the rack pre-tightening spring can be changed by pushing the pre-tightening rack, so that the arc-shaped clamping assembly slides to the position of clamping the to-be-tested pick and applies a certain clamping force.

[0021] Furthermore, the direction adjustment and holding mechanism includes a folding top contact device and a magnetic adsorption type direction adjustment component. The folding top contact device is arranged on the clamping sliding component, and the magnetic adsorption type direction adjustment component is arranged on the clamping sliding component.

[0022] Preferably, the foldable top contact device is arranged on the bottom plate. The magnetic attraction type direction adjustment assembly includes a lifting sleeve, a lifting thimble, a thimble spring and an iron ring. The lifting sleeve is arranged on the bottom plate. The lifting thimble is clamped and slidably arranged in the lifting sleeve. The thimble spring is arranged between the lifting sleeve and the lifting thimble. The iron ring is fixedly connected to the outside of the lifting sleeve, and there is an attractive force between the magnetized pick to be measured and the iron ring.

[0023] The magnetized pick to be measured can be attracted through the iron ring, so as to adjust and limit the direction of the pick to be measured. By the way that the lifting thimble contacts the bottom of the pick to be measured, the pick to be measured can be magnetized, and the position of the central axis during the self-rotation of the pick to be measured can also be limited, thereby improving the stability of the pick to be measured in the vertical direction.

[0024] Furthermore, the transmission mechanism includes a reciprocating conveying assembly, a magnetic suspension spraying device and a scanning detection device. The magnetic suspension spraying device and the scanning detection device are arranged on the reciprocating conveying assembly.

[0025] Preferably, the reciprocating conveying assembly includes a conveying frame, rollers and a conveyor belt. The rollers are rotatably arranged on the conveying frame. The conveyor belt is in rolling contact with the rollers. The magnetic suspension spraying device and the scanning detection device are arranged on the conveying frame. The bottom plate is arranged on the conveyor belt.

[0026] The beneficial effects obtained by the present invention with the above structure are as follows: (1) Through the adaptive clamping mechanism, without setting an independent lifting control module, by using the clamping driving assembly to drive the clamping device, the height adjustment of the pick to be measured can be realized simultaneously, thereby improving the clamping stability; compared with the traditional technical solution, the structure and operation steps are simplified.

[0027] (2) By sliding the two sliding plates, the size of the gap for clamping the pick to be measured can be changed, so as to automatically adapt to the diameter size of the handle part of the pick to be measured with different specifications; by the way that the rack pre-tightening spring provides a pre-tightening force, it can automatically adapt to picks to be measured with different specifications, so as to achieve the technical effect of automatically clamping the pick to be measured with an unknown diameter without setting a sensor.

[0028] (3) Through the overall swing of the arc-shaped clamping assembly, the lifting of the pick to be measured can be controlled, so as to complete the longitudinal position adjustment of the pick to be measured. It can not only install the pick to be measured to a position convenient for the magnetic ring, but also improve the clamping firmness.

[0029] When the adaptive clamping mechanism moves as a whole, by releasing the rotating cable, the winding wheel can drive one of the clamping wheels connected thereto to rotate, while the winding spring accumulates elastic potential energy. When resetting, the winding wheel will rewind the rotating cable under the elastic force of the winding spring.

[0030] (5)Through the transmission of the gear shaft, on the one hand, the swinging of the arc-shaped clamping assembly can be controlled, and on the other hand, the compression amount of the rack pre-tightening spring can be changed by pushing the pre-tightening rack, so that the arc-shaped clamping assembly slides to the position where the to-be-tested pick is clamped and applies a certain clamping force.

[0031] (6)The magnetized to-be-tested pick can be attracted by the iron ring, so as to adjust and limit the direction of the to-be-tested pick. By the way that the lifting thimble contacts the bottom of the to-be-tested pick, the to-be-tested pick can be magnetized and the position of the central axis during the self-rotation of the to-be-tested pick can be limited, thereby improving the stability of the to-be-tested pick in the vertical direction.

[0037] As Figures 1 to 11 shown, the present invention provides a tooth pick magnetic particle flaw detection flow operation tooling, including an adaptive clamping mechanism 1, a lifting mechanism 2, a direction adjustment and holding mechanism 3, and a transmission mechanism 4.

The bottom plate 9 is arranged on the conveyor belt 42.

[0040] The adaptive clamping mechanism 1 includes a clamping sliding assembly 5, an elastic clamping assembly 6, an arc-shaped clamping assembly 7, and a self-rotation driving assembly 8. The clamping sliding assembly 5 is arranged on the reciprocating conveying assembly 37. The elastic clamping assembly 6 is arranged on the clamping sliding assembly 5. The arc-shaped clamping assembly 7 is arranged on the clamping sliding assembly 5. The self-rotation driving assembly 8 is arranged on the arc-shaped clamping assembly 7.

[0041] Through the adaptive clamping mechanism 1, without setting up an independent lifting control module, by using the driving of the clamping driving component 24 for the clamping device, the height adjustment of the to-be-tested pick 43 can be realized simultaneously, thereby improving the clamping stability; compared with the traditional technical solution, the structure and operation steps are simplified.

[0042] The clamping sliding assembly 5 includes a bottom plate 9, a guide rail 10, a slider 11, and a sliding plate 12. The bottom plate 9 is arranged on the reciprocating conveying assembly 37. The guide rail 10 is arranged on the bottom plate 9. The slider 11 is engaged and slidably arranged on the guide rail 10. The sliding plate 12 is arranged on the slider 11. The sliding plates 12 are symmetrically arranged.

[0043] The elastic clamping assembly 6 includes a rack guiding bracket 13, a pre-tightening rack 14, a spring bracket 15, and a rack pre-tightening spring 16. The rack guiding bracket 13 is fixedly connected to the sliding plate 12. The pre-tightening rack 14 is engaged and slidably arranged in the rack guiding bracket 13. The spring bracket 15 is arranged on the bottom plate 9. The rack pre-tightening spring 16 is arranged between the pre-tightening rack 14 and the spring bracket 15.

[0044] By sliding the two sliding plates 12, the gap size for clamping the to-be-tested pick 43 can be changed, so that for to-be-tested picks 43 of different specifications, the diameter size of the handle part can be automatically adapted; by providing a pre-tightening force through the rack pre-tightening spring 16, to-be-tested picks 43 of different specifications can be automatically adapted, so as to achieve the technical effect of automatically clamping the to-be-tested pick 43 with an unknown diameter without setting up a sensor.

[0045] The direction adjustment and holding mechanism 3 includes a folding top contact device 31 and a magnetic adsorption type direction adjustment component 32. The folding top contact device 31 is arranged on the clamping sliding assembly 5. The magnetic adsorption type direction adjustment component 32 is arranged on the clamping sliding assembly 5.

[0046] The foldable top contact device 31 is arranged on the bottom plate 9. The magnetic attraction type direction adjustment component 32 includes a lifting sleeve 33, a lifting ejector pin 34, an ejector pin spring 35 and an iron ring 36. The lifting sleeve 33 is arranged on the bottom plate 9. The lifting ejector pin 34 is engaged and slidably arranged in the lifting sleeve 33. The ejector pin spring 35 is arranged between the lifting sleeve 33 and the lifting ejector pin 34. The iron ring 36 is fixedly connected to the outside of the lifting sleeve 33. There is an attractive force between the magnetized cutting pick 43 to be measured and the iron ring 36.

[0047] The magnetized cutting pick 43 to be measured can be attracted through the iron ring 36, so as to adjust and limit the direction of the cutting pick 43 to be measured. By the way that the lifting ejector pin 34 contacts the bottom of the cutting pick 43 to be measured, not only can the cutting pick 43 to be measured be magnetized, but also the position of the central axis during the self-rotation of the cutting pick 43 to be measured can be limited, thereby improving the stability of the cutting pick 43 to be measured in the vertical direction.

[0048] The arc-shaped clamping component 7 includes a fork bracket 17, a main rotating shaft 18, an arc-shaped bracket 19 and a clamping wheel 20. The fork bracket 17 is arranged on the sliding plate 12. The main rotating shaft 18 is rotatably arranged in the fork bracket 17. The arc-shaped bracket 19 is fixedly connected to the main rotating shaft 18. The clamping wheel 20 is rotatably arranged on the arc-shaped bracket 19. The outer contours of the arc-shaped bracket 19 and the clamping wheel 20 are continuous arcs.

[0049] Through the overall swing of the arc-shaped clamping component 7, the lifting of the cutting pick 43 to be measured can be controlled, so as to complete the longitudinal position adjustment of the cutting pick 43 to be measured. Not only can the cutting pick 43 to be measured be installed at a position convenient for the magnetic ring, but also the clamping firmness can be improved.

[0050] The self-rotation driving component 8 includes a winding wheel 21, a rotating pull rope 22 and a winding spring 23. The winding wheel 21 is fixedly connected to the clamping wheel 20 at the top. The rotating pull rope 22 is wound around the winding wheel 21. The end of the rotating pull rope 22 is arranged on the external frame. The winding spring 23 is arranged between the winding wheel 21 and the arc-shaped bracket 19.

[0051] When the adaptive clamping mechanism 1 moves as a whole, through the release of the rotating pull rope 22, the winding wheel 21 can drive one clamping wheel 20 connected thereto to rotate, and at the same time the winding spring 23 stores elastic potential energy. When resetting, the winding wheel 21 will rewind the rotating pull rope 22 under the elastic force of the winding spring 23.

[0052] The lifting mechanism 2 includes a clamping driving component 24 and a transmission component 25. The clamping driving component 24 is arranged on the bottom plate 9. The transmission component 25 is rotatably arranged on the arc-shaped clamping component 7.

[0053] The clamping drive assembly 24 includes a drive motor 26, a drive gear 27 and a gear shaft 28. The drive motor 26 is arranged on the bottom plate 9, the drive gear 27 is arranged on the output shaft of the drive motor 26, the gear shaft 28 is rotatably arranged on the fork 17, and the gear shaft 28 and the drive gear 27 are in meshing transmission.

[0054] The transmission assembly 25 includes a clamping gear 29 and a transmission gear 30. The clamping gear 29 is fixedly connected to the main rotating shaft 18, the clamping gear 29 and the gear shaft 28 are in meshing transmission, the transmission gear 30 is fixedly connected to one end of the main rotating shaft 18, and the transmission gear 30 and the pre-tightening rack 14 are in meshing transmission.

[0055] Through the transmission of the gear shaft 28, on the one hand, the swing of the arc-shaped clamping assembly 7 can be controlled, and on the other hand, the compression amount of the rack pre-tightening spring 16 can be changed by pushing the pre-tightening rack 14, so that the arc-shaped clamping assembly 7 slides to the position where the test pick 43 to be clamped is located and applies a certain clamping force.

[0056] During specific use, an external motor drives the roller 41 to rotate, thereby driving the conveyor belt 42 to reciprocate. During this process, the bottom plate 9 also reciprocates and slides along with the conveyor belt 42; Embodiment 1: When the bottom plate 9 is stationary at the starting position, the test pick 43 to be measured is placed at a specific height directly above the bottom plate 9 through an external clamping mechanism, and then the drive motor 26 is started. The rotation of the drive gear 27 drives the gear shaft 28 and the main rotating shaft 18 to rotate. When the gear shaft 28 drives the transmission gear 30 to rotate, since the transmission gear 30 and the pre-tightening rack 14 are in meshing, the pre-tightening rack 14 will slide along the rack guide bracket 13 towards the direction close to the spring bracket 15. At this time, the compression amount and elastic force of the rack pre-tightening spring 16 increase; Under the action of the elastic force, the symmetrically arranged sliding plates 12 will slide along the sliders 11 towards the middle position. When the rotating pull rope 22 contacts the handle part of the test pick 43, the sliding plates 12 will stop sliding; then the rack pre-tightening spring 16 continues to deform, and the extrusion force between the clamping wheel 20 and the test pick 43 also increases accordingly, thereby improving the stability of the test pick 43 after being clamped; For the above clamping method, although it can adapt to various specifications of the test pick 43 within a certain range, due to the absence of a rigid locking mechanism and only four points in the same plane in contact, even if there is a certain clamping force and the test pick 43 can be restricted in height, it is still not stable enough in the angular direction.

[0057] Embodiment 2: While the main rotating shaft 18 is rotating, the fork 17 also rotates itself to lower the to-be-tested pick 43. After the bottom end of the to-be-tested pick 43 contacts the thimble spring 35, it will retract into the lifting sleeve 33. By supporting the point at the center of the bottom of the to-be-tested pick 43 through the lifting thimble 34, the stability of the to-be-tested pick 43 during subsequent self-rotation can be improved; then the foldable top contact device 31 unfolds until it contacts the top of the to-be-tested pick 43; At this time, through the two metal contact points of the lifting thimble 34 and the foldable top contact device 31, the to-be-tested pick 43 can be magnetized by being energized. After magnetization, an attractive force will be generated between the to-be-tested pick 43 and the iron ring 36. This attractive force is vertically downward and can adjust the to-be-tested pick 43 to a vertically downward angle; When the fork 17 swings to the position where the uppermost set of clamping wheels 20 contacts the to-be-tested pick 43 and stops, at this time, the winding wheel 21 is approximately at a horizontal angle.

[0058] Embodiment 3: After the clamping fixation and direction adjustment are both completed, the to-be-tested pick 43 is moved by the movement of the conveyor belt 42. Since one end of the winding wheel 21 is fixed to the external frame, during the movement of the conveyor belt 42, the winding wheel 21 will rotate by releasing the rotating pull rope 22, and at the same time drive the uppermost clamping wheel 20 to rotate. The rotating directions of each group of clamping wheels 20 are the same. Therefore, the to-be-tested pick 43 clamped by the clamping wheels 20 will rotate while following the movement of the conveyor belt 42; Due to the self-rotation of the to-be-tested pick 43, neither the magnetic suspension spraying device 38 nor the scanning detection device 39 needs to be set in multiple directions. When the to-be-tested pick 43 rotates past the magnetic suspension spraying device 38, the magnetic suspension spraying device 38 can spray the magnetic suspension with magnetic powder on the surface of the to-be-tested pick 43. By changing the movement speed of the conveyor belt 42, the self-rotation speed of the to-be-tested pick 43 can be adjusted, thereby appropriately increasing the centrifugal force of the to-be-tested pick 43 to remove the excess magnetic powder and improve the obviousness of the scar position; When the to-be-tested pick 43 moves to the scanning detection device 39, the magnetic powder distribution on the surface of the to-be-tested pick 43 can be detected through machine vision, so as to feedback the scar condition on or near the surface of the to-be-tested pick 43.

[0059] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0060] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
