Description

Technical Field

[0001] This utility model belongs to the field of non-destructive testing technology, and in particular relates to a flaw detection spraying device for industrial non-destructive testing. Background Technology

[0002] Non-destructive testing (NDT) is a method of observing defects using magnetic powder as the display medium. First, the workpiece, made of ferromagnetic material, is magnetized. Then, a magnetic suspension is applied to the workpiece. Due to discontinuities within the workpiece, a leakage magnetic field is generated on the surface of the defect, causing the magnetic suspension to adhere to the leakage magnetic field. Under suitable lighting, this forms a visually visible magnetic trace, thus revealing the location, size, shape, and severity of the discontinuity. After testing, the magnetic suspension remaining on the workpiece can cause damage.

[0003] Existing devices, when spraying coatings on workpieces, fail to coat the clamping area with magnetic suspension fluid, resulting in incomplete detection during workpiece inspection. Therefore, an industrial non-destructive testing coating device that can solve the above problems is proposed. Utility Model Content

[0004] This utility model provides an industrial non-destructive testing spraying device, which aims to solve the problem that existing devices cannot fully coat the magnetic suspension fluid when spraying workpieces, resulting in incomplete detection during workpiece inspection.

[0005] This utility model is implemented as follows: an industrial non-destructive testing flaw detection spraying device includes a base plate, on which a spraying assembly for spraying workpieces is provided. The spraying assembly includes a spraying unit and a power unit. A collection box is fixedly connected to the base plate, and a placement unit for placing workpieces is provided on the collection box. The power unit cooperates with the placement unit to adjust the placement position of the workpieces.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0014] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0015] This utility model provides an industrial non-destructive testing spraying device, such as... Figures 1-4 As shown, the device includes a base plate 1, on which a spraying assembly for spraying workpieces is provided. The spraying assembly includes a spraying unit and a power unit. A collection box 2 is fixedly connected to the base plate 1. A placement unit for placing workpieces is provided on the collection box 2. The power unit cooperates with the placement unit to adjust the placement position of the workpieces.

[0016] In actual use, the above-mentioned device places the workpiece in the placement unit, and then the power unit drives the spraying unit to spray the workpiece repeatedly. While providing power, the power unit can also drive the placement unit to adjust the position of the workpiece to ensure the uniformity and accuracy of the spraying.

[0017] The power unit includes two symmetrically arranged first connecting plates 3 fixedly connected to the collection box 2. A power motor 4 is fixedly connected to one of the first connecting plates 3. A reciprocating lead screw 5 is fixedly connected to the output end of the power motor 4. The end of the reciprocating lead screw 5 is connected to the other end of the first connecting plate 3. A reciprocating slider 6 is sleeved on the outside of the reciprocating lead screw 5. A limit rod 7 is fixedly connected between the two first connecting plates 3. The limit rod 7 passes through the reciprocating slider 6.

[0018] When the aforementioned power unit is actually in use, the power motor 4 rotates, driving the reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 drives the reciprocating slider 6 to move back and forth, thereby driving the related components connected to the reciprocating slider 6 to move back and forth in the direction of the reciprocating screw 5.

[0019] Combination Figure 4 The spraying unit includes a connecting ring 8, which is fixedly connected to the reciprocating slider 6 via a first connecting rod 9. A plurality of spraying heads 10 arranged in a circular array are fixedly connected to the inward side of the connecting ring 8. A spraying pump 11 is fixedly connected to the reciprocating slider 6, and the output end of the spraying pump 11 is connected to the connecting ring 8 via a connecting pipe 12.

[0020] When the above-mentioned spraying unit is actually used, the spraying pump 11 pumps out the spraying liquid and sprays it out through the spraying head 10 arranged in a circumferential array, so as to uniformly spray the spraying liquid onto the workpiece for further inspection.

[0021] Combination Figure 2 and Figure 3 The placement unit includes multiple placement rods 13 arranged in an array. The multiple placement rods 13 are arranged at the upper end of the collection box 2. Two sets of symmetrically arranged second connecting plates 14 are fixedly connected to the collection box 2. A guide rod 15 is fixedly connected between each set of second connecting plates 14. The guide rod 15 passes through the placement rod 13. Adjacent second connecting plates 14 and placement rods 13 are connected by springs 16 for providing elasticity.

[0022] A third connecting plate 17 is fixedly connected to the side of the connecting ring 8. A plurality of arrayed adjusting blocks 18 are fixedly connected to the upper end of the third connecting plate 17. An adjusting curved surface 19 is provided on the adjusting block 18. An adjusting rod 20 that cooperates with the adjusting block 18 is fixedly connected to the lower end of the placement rod 13.

[0023] When the above-mentioned placement unit is actually used, the connecting ring 8 moves back and forth, which drives the third connecting plate 17 to move. When the adjusting surface 19 on the adjusting block 18 on the third connecting plate 17 contacts the adjusting rod 20, it drives the adjusting rod 20 to move to both sides, compressing or stretching the spring 16. After the adjusting block 18 is separated from the adjusting rod 20, the placement rod 13 moves in the direction of the guide rod 15 under the elastic force of the spring 16, causing the workpiece to change position and the spraying to be more thorough.

[0024] In summary, the working principle of this utility model is as follows: the placement unit places the workpiece, and then the power unit drives the spraying unit to reciprocate to spray the workpiece. While providing power, the power unit also drives the placement unit to adjust the position of the workpiece to ensure the uniformity and accuracy of the spraying. The rotation of the power motor 4 drives the reciprocating screw 5 to rotate, and the rotation of the reciprocating screw 5 drives the reciprocating slider 6 to move reciprocally, which in turn drives the related components connected to the reciprocating slider 6 to move reciprocally in the direction of the reciprocating screw 5. The spraying pump 11 pumps out the spraying liquid and passes it through a circumferential array. The spray head 10 sprays out the coating liquid, which is evenly sprayed onto the workpiece for further inspection. When the connecting ring 8 reciprocates, it drives the third connecting plate 17 to move. When the adjusting surface 19 on the adjusting block 18 on the third connecting plate 17 contacts the adjusting rod 20, it drives the adjusting rod 20 to move to both sides, compressing or stretching the spring 16. After the adjusting block 18 disengages from the adjusting rod 20, the placing rod 13 moves in the direction of the guide rod 15 under the elastic force of the spring 16, causing the workpiece to change position and making the coating more thorough.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
