Description

Technical Field

[0001] The utility model relates to the technical field of magnetic particle flaw detectors, in particular to a semi-automatic fluorescent magnetic particle flaw detector. Background Art

[0002] In nature, magnetic lines of force always maintain their continuity. When a ferromagnetic workpiece is placed in a saturated magnetic field, the magnetic lines of force will be guided through the workpiece. If the magnetic lines of force encounter discontinuities in the workpiece material, they will bypass these areas of low magnetic permeability and leak out of the workpiece surface to form a "leakage magnetic field." In this way, magnetic poles will be generated on both sides of the defect, attracting magnetic powder around defects such as cracks, forming clearly visible linear or dot-shaped accumulations. Existing fluorescent magnetic particle flaw detectors use the above method to inspect tubular parts.

[0003] The fluorescent magnetic particle flaw detector needs to fix the tubular parts before inspecting them, and then spray the suspension onto their surface while rotating the tubular parts. The lengths of the tubular parts to be inspected vary, and the fluorescent magnetic particle flaw detector cannot quickly adjust itself to fix them according to the length of the tubular parts to be inspected, making it less practical. Utility Model Content

[0007] In order to better achieve the above-mentioned purpose, the present invention adopts a further technical solution: the liquid supply assembly includes a reciprocating screw rotatably mounted on the surface of a fixed seat, a slide threadedly sleeved on the reciprocating screw, a piston rod fixedly mounted on the surface of the slide and a hollow rod with a closed end, the hollow rod is fixedly connected to the lower surface of the placement plate through a connecting rod, the piston rod sliding seal is inserted in the hollow rod, the hollow rod is connected to the liquid storage tank and the liquid guide box through a liquid inlet pipe and a liquid outlet pipe respectively, and a one-way valve is provided in the liquid inlet pipe and the liquid outlet pipe. The reciprocating screw is controlled to rotate by a transmission component, and the transmission component includes two sprockets and a chain fixedly sleeved on the reciprocating screw and the output shaft of the drive motor respectively, and the chain is meshed and wound around the two sprockets.

[0008] In order to better achieve the above purpose, the present invention adopts a further technical solution: the conducting direction of the one-way valve in the liquid inlet pipe is from the liquid storage tank to the hollow rod, and the conducting direction of the one-way valve in the liquid outlet pipe is from the hollow rod to the liquid guide box.

[0009] In order to better achieve the above-mentioned purpose, the utility model adopts a further technical solution: a sliding opening is horizontally opened at one end of the liquid guide box away from the fixed seat, and a U-shaped baffle is sealed and slidably configured in the sliding opening. The end of the baffle located on the outside is fixedly connected to the surface of the movable seat, and the baffle is used to cover the pipe openings of multiple liquid inlet pipes located in the liquid guide box.

[0010] In order to better achieve the above-mentioned purpose, the present invention adopts a further technical solution: an anti-slip layer is bonded to the wall of the regulating wheel, and the material of the anti-slip layer is rubber.

[0011] The advantages of the utility model are:

[0012] Through the cooperation between the threaded rod, the movable seat and the fixed seat, tubular parts of different lengths can be quickly pressed and fixed, which is convenient and quick, and improves the practicality of the device.

There is no need to manually spray the suspension on the surface of the tubular part, which reduces the labor burden of the staff.

[0014] Under the action of the baffle, only the liquid tube corresponding to the position of the tubular part will flow out the suspension, while the liquid tube not corresponding to the position of the tubular part will be in a closed state and unable to flow out the suspension, thereby avoiding multiple liquid tubes being in an open state all the time and being unable to adjust the switch according to the length of the tubular part, resulting in waste of suspension.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Reference Figure 1-Figure 5 As shown, the semi-automatic fluorescent magnetic particle flaw detector includes a table 1, a fixed seat 2 is fixedly installed on the upper surface of the table 1, a drive motor 3 is fixedly installed on the surface of the fixed seat 2, the output shaft of the drive motor 3 passes through the fixed seat 2 and is fixedly installed with a disc 4, a mounting groove is horizontally opened on the upper surface of the table 1, a threaded rod 5 is horizontally rotatably installed in the mounting groove, a slider 6 is threadedly sleeved on the threaded rod 5, a moving seat 7 is fixedly installed on the top of the slider 6, a rotating groove is opened on the surface of the moving seat 7, a turntable 8 is rotatably installed in the rotating groove, one end of the threaded rod 5 passes through the table 1 and is fixedly installed with an adjusting wheel, and an anti-slip layer is bonded to the wall of the adjusting wheel, and the material of the anti-slip layer is rubber. The anti-slip layer of rubber can increase the friction between the contact surface between the adjusting wheel and the palm.

[0023] Before fixing the tubular part to be inspected, first place it horizontally between the turntable 8 and the butt plate 4, and make one end of it butt against the surface of the butt plate 4, then by rotating the threaded rod 5, the slider 6 threaded on the threaded rod 5 will move the movable seat 7 laterally, and control the movable seat 7 to move in the direction close to the tubular part until the turntable 8 and the end of the tubular part away from the butt plate 4 are tightly butted against each other, and the tubular part can be pressed and fixed quickly. Tubular parts of different lengths can be fixed quickly and conveniently, and after starting the drive motor 3, the drive motor 3 will rotate the tubular part that is pressed and fixed.

[0024] A placement plate is fixedly installed on the upper surface of the platform 1, and a liquid storage tank 9 is fixedly installed on the upper surface of the placement plate. The liquid storage tank 9 is filled with a suspension. A liquid guide box 10 is fixedly installed on the lower surface of the placement plate through two connecting rods. A plurality of liquid pipes 11 are fixedly installed at the bottom of the liquid guide box 10 at equal intervals. A liquid supply component is provided on the lower surface of the liquid storage tank 9. The liquid supply component is used to supply the suspension in the liquid storage tank 9 to the liquid guide box 10. The liquid supply component includes a reciprocating screw rod 12 rotatably installed on the surface of the fixed seat 2, a slide plate 13 threadedly sleeved on the reciprocating screw rod 12, a piston rod 14 fixedly installed on the surface of the slide plate 13, and a hollow rod 15 with a closed design at one end. The hollow rod 15 is connected to the placement plate by a connecting rod. The lower surface of the plate is fixedly connected, and the piston rod 14 is slidingly sealed and inserted in the hollow rod 15. The hollow rod 15 is connected to the liquid storage tank 9 and the liquid guide box 10 through the liquid inlet pipe 16 and the liquid outlet pipe 17 respectively. A one-way valve is provided in the liquid inlet pipe 16 and the liquid outlet pipe 17. The conduction direction of the one-way valve in the liquid inlet pipe 16 is from the liquid storage tank 9 to the hollow rod 15, and the conduction direction of the one-way valve in the liquid outlet pipe 17 is from the hollow rod 15 to the liquid guide box 10. The reciprocating screw 12 is controlled to rotate by a transmission component, and the transmission component includes two sprockets 18 and a chain 19 which are respectively fixedly sleeved on the reciprocating screw 12 and the output shaft of the drive motor 3. The chain 19 is meshed and wound around the two sprockets 18.

[0025] When the output shaft of the driving motor 3 rotates together with the disc 4, the fixed tubular part and the turntable 8, the reciprocating screw 12 will also rotate together under the transmission action of the two sprockets 18 and the chain 19. The slide 13 threadedly connected to the reciprocating screw 12 will carry the piston rod 14 to move back and forth horizontally. During the reciprocating movement of the piston rod 14, the volume inside the hollow rod 15 will continue to change from small to large and then from large to small. When the volume inside the hollow rod 15 increases, the pressure decreases, and the liquid in the liquid storage tank 9 is released. The suspension inside will enter the hollow rod 15 from the liquid inlet pipe 16. When the volume inside the hollow rod 15 becomes smaller, the pressure increases, and the suspension in the hollow rod 15 will enter the liquid guide box 10 from the liquid outlet pipe 17, and then flow out from the multiple liquid pipes 11, and then act on the surface of the rotating tubular parts, thereby achieving the effect of automatically applying the suspension to the surface of the tubular parts. There is no need to manually spray the suspension on the surface of the tubular parts, which reduces the labor burden of the staff and does not require an additional electric drive device, so no additional electricity cost is generated.

[0026] A sliding opening is horizontally opened at one end of the liquid conducting box 10 away from the fixed seat 2, and a U-shaped baffle 20 is sealed and slidably configured inside the sliding opening. The baffle 20 is fixedly connected to the surface of the movable seat 7 at one end located on the outside, and the baffle 20 is used to cover the pipe openings of multiple liquid inlet pipes 16 located in the liquid conducting box 10.

[0027] When the movable seat 7 moves laterally with the turntable 8, the baffle 20 will also move together. When the tubular part is fixed, the distance between the plate 4 and the turntable 8 is the length of the tubular part. At this time, the pipe openings of the multiple liquid tubes 11 corresponding to the position of the tubular part will all be in an open state, and the pipe openings of the liquid tubes 11 that do not correspond to the position of the tubular part will be covered by the baffle 20. In this way, when the tubular part rotates, the suspension in the liquid guide box 10 will only flow out from the liquid tubes 11 that are in an open state, so that the outflowing suspension can completely act on the surface of the tubular part, avoiding the liquid tubes 11 that do not correspond to the position of the tubular part from flowing out the suspension, resulting in waste of the suspension.

[0028] Before fixing the tubular part to be inspected, first place it horizontally between the turntable 8 and the butt plate 4, and make one end of it butt against the surface of the butt plate 4, then by rotating the threaded rod 5, the slider 6 threaded on the threaded rod 5 will move the movable seat 7 laterally, and control the movable seat 7 to move in the direction close to the tubular part until the turntable 8 and the end of the tubular part away from the butt plate 4 are tightly butted against each other, and the tubular part can be pressed and fixed. Tubular parts of different lengths can be fixed quickly, which is convenient and fast, and improves the practicality of the device. After starting the drive motor 3, the drive motor 3 will rotate with the tubular part that is pressed and fixed.
