Description

Technical Field

[0001] The utility model relates to the technical field of flaw detectors, in particular to a special fluorescent magnetic particle flaw detector for six-way magnetized steering knuckles. Background Technique

[0002] Magnetic particle flaw detection utilizes the interaction between the leakage magnetic field at the workpiece defect and the magnetic powder. It makes use of the difference in magnetic permeability between the surface and near-surface defects of steel products and the magnetic permeability of steel. After magnetization, the magnetic field at these material discontinuities will be distorted, forming a leakage magnetic field on the workpiece surface at the partial magnetic flux leakage points, thereby attracting magnetic powder to form a magnetic powder accumulation at the defect. Under appropriate lighting conditions, the position and shape of the defect are revealed.

[0003] In the existing six-way magnetized steering knuckle flaw detection technology, the six-way magnetized steering knuckle is fixedly installed on the device, and the host controls the fixed device to rotate, thereby controlling the six-way magnetized steering knuckle to rotate for detection. However, in this process, the six-way magnetized steering knuckle is in a continuous rotation state, and it is impossible to grasp the detection angle accurately, resulting in undetected positions and thus affecting the accuracy of the detection result. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that the angle of the six-way magnetized steering knuckle cannot be freely adjusted, and a special fluorescent magnetic particle flaw detector for six-way magnetized steering knuckles is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A special fluorescent magnetic particle flaw detector for six-way magnetized steering knuckles, including a main body equipped with a fluorescent magnetic particle flaw detector. A driven turntable is rotatably installed on the main body, and a fixing mechanism for fixing the six-way magnetized steering knuckle is arranged on the driven turntable. A cavity is opened in the main body, and a driving motor is fixedly installed on one side of the main body. A rotating mechanism for controlling the rotation of the driven turntable and driven by the driving motor is arranged in the cavity. A collecting frame for collecting fluorescent magnetic powder is slidably installed at the bottom end of the main body. The fixing mechanism includes a guide post welded to the driven turntable. A long guide hole is opened in the guide post. A ball screw rotatably connected to the guide post is rotatably installed on the driven turntable. An internal hexagonal hole column is welded to the free end of the ball screw. A sliding nut threadedly connected to the ball screw is slidably installed in the guide post. Four guide rods corresponding to the long guide holes are rotatably installed on the sliding nut. The free ends of the four guide rods are all rotatably connected to a support plate that abuts against the six-way magnetized steering knuckle from the inside to the outside, and the four support plates are slidably installed on the driven turntable.

[0007] To better achieve the above object, the utility model adopts the following further technical solution: the four groups of the supporting plates are all arc-shaped structures that fit the inner circle of the six-way magnetized knuckle, and the four groups of supporting plates are circumferentially equidistantly distributed. The four groups of guiding long holes are equidistantly distributed on the guiding column, and the guiding rod slidably penetrates through the guiding long holes.

[0008] To better achieve the above object, the utility model adopts the following further technical solution: the rotating mechanism includes a transmission turntable fixedly installed on the driven turntable. A driving turntable in abutting connection with the transmission turntable is installed in a matching manner at the output end of the driving motor. A telescopic rod is fixedly installed in the driving turntable, and a strong spring located outside the telescopic rod is welded in the driving turntable. A sliding rod connected to the free ends of the telescopic rod and the strong spring is slidably installed in the driving turntable.

[0009] To better achieve the above object, the utility model adopts the following further technical solution: four groups of equally spaced slot holes are formed at the middle position of the transmission turntable, and four groups of equally spaced arc-shaped notches in abutting connection with the driving turntable are formed at the corners of the transmission turntable.

[0010] The advantages of the utility model are as follows: aiming at the characteristic of the six-way magnetized knuckle having circular holes, the six-way magnetized knuckle is sleeved on the supporting plates. The ball screw is controlled to rotate counterclockwise, and the supporting plates are pulled outwards by the guiding rods to support, so as to fix the six-way magnetized knuckle on the machine. The driving motor is used to control the rotation of the driving turntable. The sliding column rotates into the slot hole to dial the transmission turntable, and then drives the transmission turntable to rotate. This rotating mechanism has the characteristic of intermittent transmission, so as to comprehensively detect the six-way magnetized knuckle. BRIEF DESCRIPTION OF THE DRAWINGS

A cavity 3 is opened in the main body 1. A driving motor 4 is fixedly installed on one side of the main body 1. A rotating mechanism for controlling the rotation of the driven turntable 2 and driven by the driving motor 4 is provided in the cavity 3. A collection box 5 for collecting fluorescent magnetic particles is slidably installed at the bottom of the main body 1. When spraying fluorescent magnetic particles on the six-way magnetized knuckle, some fluorescent magnetic particles will fall into the collection box 5. The fixing mechanism includes a guide post 6 welded to the driven turntable 2. A guide long hole 7 is opened in the guide post 6. A ball screw 8 rotatably connected to the guide post 6 is rotatably installed on the driven turntable 2. A hexagon socket head cap screw 9 is welded to the free end of the ball screw 8. A sliding nut 10 threadedly connected to the ball screw 8 is slidably installed in the guide post 6. Four groups of guide rods 11 corresponding to the guide long holes 7 are rotatably installed on the sliding nut 10. The free ends of the four groups of guide rods 11 are all rotatably connected to support plates 12 that abut against the six-way magnetized knuckle from the inside to the outside. The four groups of support plates 12 are slidably installed on the driven turntable 2. The movement of the guide rods 11 is synchronously controlled by the sliding nut 10 to pull the four groups of support plates 12 to slide synchronously, making the fixation of the six-way magnetized knuckle more reliable.

[0019] The four groups of support plates 12 are all arc-shaped structures that fit the inner circle of the road magnetized knuckle. The arc-shaped structure fits better with the external structure of the six-way magnetized knuckle, enabling it to be stably sleeved on the support plates 12. The four groups of support plates 12 are circumferentially equidistantly distributed. The four groups of guide long holes 7 are equidistantly distributed on the guide post 6, and the guide rods 11 slide through the guide long holes 7.

[0021] Four groups of equally spaced slots 1301 are provided at the middle of the transmission turntable 13, and four groups of equally spaced arc-shaped notches 1302 are provided at the corners of the transmission turntable 13 to contact the driving turntable 14. The arc-shaped notches 1302 are always in contact with the driving turntable 14 to ensure the stability of the transmission.

[0022] It should be noted that the specific model and specifications of the drive motor 4 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0023] When the utility model is used, the six-way magnetized steering knuckle is mounted on the support plate 12, and the ball screw 8 is screwed counterclockwise with an inner hexagonal wrench to control the sliding nut 10 to move downward, and the support plate 12 is pulled by the guide rod 11 to slide outward, so that the six-way magnetized steering knuckle is supported and fixed from the inside out; the drive motor 4 is started to control the drive turntable 14 to rotate, and when the slide rod 17 moves into the slot 1301, the transmission turntable 13 is toggled to rotate, thereby driving the driven turntable 2 to rotate, thereby controlling the six-way magnetized steering knuckle to rotate intermittently.
