Description

Technical Field

[0001] This utility model belongs to the field of magnetic particle testing technology, and in particular relates to a positioning fixture for magnetic particle testing with an anti-deviation mechanism. Background Technology

[0002] Magnetic particle testing is a method that utilizes the property of magnetic powder sprayed onto the surface of magnetic metal parts. The magnetic force distribution at the defects on the surface of the parts causes the magnetic powder to fill the defects, thus detecting defects on the surface of magnetic metal parts. This method can accurately detect defects on the surface of magnetic metal parts.

[0003] During the dry magnetic particle inspection of welded joints of pipe fittings, the curved surface of the fittings causes the magnetic powder to easily slide to both sides after being sprayed. Furthermore, external influences can cause the magnetic powder to shift and slide off the fitting surface, preventing it from remaining on the surface. This makes magnetic particle inspection difficult and affects the inspection results. To address these issues, a positioning fixture with an anti-deviation mechanism for magnetic particle inspection is urgently needed. Utility Model Content

[0004] The purpose of this invention is to address the problem that during dry magnetic particle testing of pipe fittings, the pipe fitting surface has a certain curvature, causing the magnetic powder sprayed onto the pipe fitting surface to easily slide to both sides. Furthermore, when the pipe fitting is affected by external factors, the magnetic powder on the pipe fitting surface may also shift and slide off, thus failing to stay on the pipe fitting surface. This makes magnetic particle testing of the pipe fitting surface difficult and affects the effectiveness of the magnetic particle testing. Therefore, this invention proposes a positioning fixture for magnetic particle testing with an anti-deviation mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning fixture for magnetic particle testing with an anti-offset mechanism, comprising a base plate, a support frame fixedly connected to the top surface of the base plate, a clamping assembly at the top of the support frame, and a receiving assembly on one side of the support frame;

[0006] The clamping assembly includes a mounting rod, an arc-shaped plate fixedly connected to one side of the mounting rod, a second threaded rod rotatably connected to the mounting rod through a groove on one side of the mounting rod, a baffle slidably connected to the mounting rod through a groove on its top surface, a support plate slidably connected to the baffle through a groove on its bottom surface, a fixing pin slidably connected to the support plate through a through hole in the support plate, and a spring fixedly connected to the top of the support plate.

[0007] As a further description of the above technical solution:

[0008] The other end of the spring is fixedly connected to the baffle, and the support plate is slidably connected to it through an opening on one side of the mounting rod.

[0009] As a further description of the above technical solution:

[0010] The fixing pin is slidably connected to the mounting rod through a through hole, and the second threaded rod is threadedly connected to the support frame through a threaded hole.

[0011] As a further description of the above technical solution:

[0012] One end of the baffle is provided with a rubber strip, and both ends of the mounting rod are provided with arc-shaped plates.

[0013] As a further description of the above technical solution:

[0014] The receiving assembly includes a mounting frame, and the mounting frame is fixedly connected to a telescopic groove through a groove opened therein.

[0015] As a further description of the above technical solution:

[0016] A slider is slidably connected inside the telescopic groove, and a support frame is fixedly connected to the top of the slider.

[0017] As a further description of the above technical solution:

[0018] The slider is threadedly connected to a first threaded rod through a threaded hole inside it, and the first threaded rod is rotatably connected to it through a through hole at the bottom of the telescopic groove.

[0019] As a further description of the above technical solution:

[0020] The mounting frame is slidably connected to a receiving groove through a groove at its bottom end, and both ends of the mounting frame are fixedly connected to a support frame.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by providing a baffle inside, when performing magnetic particle testing on the pipe fitting, the pipe fitting is placed between the arc-shaped plates, and the pipe fitting is fixed by rotating the second threaded rod, causing the arc-shaped plates to contact the pipe fitting. At the same time, the spring is compressed. In use, the baffle can be moved to a suitable height by moving the support plate, and then fixed by inserting the fixing pin into the support plate and the mounting rod. Through this design, if the magnetic powder on the top surface of the pipe fitting slips during magnetic powder spraying, the baffle can block the magnetic powder and allow it to accumulate on the baffle. When the accumulation reaches a certain level, it can prevent the magnetic powder on the top of the pipe fitting from continuing to slip, so that the magnetic particle testing can achieve the corresponding effect. Furthermore, by fixing the pipe fitting with the baffle and the arc-shaped plate, it can effectively avoid the deviation caused by the influence of the external environment on the pipe fitting, thereby enabling the testing to be carried out accurately.

[0023] 2. In this utility model, by providing an internal mounting frame, during the inspection of the pipe fitting, if it is necessary to rotate the pipe fitting, the first threaded rod can be rotated to bring the lifting frame into contact with the pipe fitting, and then the second threaded rod can be slightly rotated to separate the arc plate from the pipe fitting. Thus, the pipe fitting can be adjusted by rotating it. During the spraying of magnetic powder, the falling magnetic powder will fall into the mounting frame and slide into the receiving trough. Through this design, when the magnetic powder is sprayed, the mounting frame can be used to collect the magnetic powder and let it slide into the receiving trough, thus facilitating the recovery of the magnetic powder. Furthermore, the lifting frame can be used to lift the pipe fitting, thus facilitating the rotation of the pipe fitting and the inspection of other parts of the pipe fitting.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a positioning fixture for magnetic particle testing with an anti-offset mechanism, including a base plate 1, a support frame 2 fixedly connected to the top surface of the base plate 1, a clamping component 4 at the top of the support frame 2, and a receiving component 3 on one side of the support frame 2;

[0032] The clamping assembly 4 includes a mounting rod 42, an arc-shaped plate 43 fixedly connected to one side of the mounting rod 42, a second threaded rod 44 rotatably connected to the mounting rod 42 through a groove on one side of the mounting rod 42, a baffle 41 slidably connected to the mounting rod 42 through a groove on its top surface, a support plate 46 slidably connected to the baffle 41 through a groove on its bottom surface, a fixing pin 45 slidably connected to the support plate 46 through a through hole in the support plate 46, and a spring 47 fixedly connected to the top of the support plate 46.

[0033] The other end of the spring 47 is fixedly connected to the baffle 41. The support plate 46 is slidably connected to it through a hole opened on one side of the mounting rod 42. The fixing pin 45 is slidably connected to it through a through hole opened in the mounting rod 42. The second threaded rod 44 is threadedly connected to it through a threaded hole opened in the support frame 2. One end of the baffle 41 is provided with a rubber strip. Both ends of the mounting rod 42 are provided with arc-shaped plates 43.

[0034] The specific implementation method is as follows: When performing magnetic particle testing on the pipe fitting, the pipe fitting is placed between the arc plates 43, and the mounting rod 42 is moved by rotating the second threaded rod 44, thereby causing the arc plates 43 to contact the pipe fitting and fixing the pipe fitting by squeezing the pipe fitting with the arc plates 43. At the same time, during the process of the arc plates 43 contacting the surface of the pipe fitting, the baffle 41 moves with the movement of the mounting rod 42, and one end of the baffle 41 contacts the pipe fitting first. At the same time, as the mounting rod 42 continues to move, the spring 47 is compressed. In use, the baffle 41 can be moved to a suitable height by moving the support plate 46, so that the baffle 41 can contact the top surface of the pipe fitting at a suitable position. Then, the fixing pin 45 is inserted into the support plate 46 and the mounting rod 42 for fixing.

[0035] The receiving assembly 3 includes a mounting frame 34, which is fixedly connected to a telescopic groove 31 through a groove opened inside it. A slider 35 is slidably connected inside the telescopic groove 31. A lifting frame 36 is fixedly connected to the top of the slider 35. A first threaded rod 32 is threadedly connected to the slider 35 through a threaded hole opened inside it. The first threaded rod 32 is rotatably connected to the telescopic groove 31 through a through hole opened at the bottom end. The receiving groove 33 is slidably connected to the mounting frame 34 through a sliding groove opened at its bottom end. Both ends of the mounting frame 34 are fixedly connected to the support frame 2.

[0036] The specific implementation method is as follows: During the inspection of the pipe fitting, if the pipe fitting needs to be rotated, the first threaded rod 32 can be rotated to drive the slider 35 and the lifting frame 36 to move upward, so that the lifting frame 36 contacts the pipe fitting. Then, the second threaded rod 44 is rotated slightly to drive the arc plate 43 to separate from the pipe fitting. At the same time, the baffle 41 is still in contact with the pipe fitting through the action of the spring 47. Thus, the pipe fitting can be adjusted by rotating it. During the process of spraying magnetic powder, the falling magnetic powder will fall into the mounting frame 34 and slide into the receiving trough 33. When the inspection is finished, the receiving trough 33 can be pulled out to recover the magnetic powder.

[0037] Working principle: When performing magnetic particle testing on pipe fittings, the pipe fitting is placed between the arc-shaped plates 43. Rotating the second threaded rod 44 moves the mounting rod 42, causing the arc-shaped plates 43 to contact the pipe fitting. The arc-shaped plates 43 then press against the pipe fitting, fixing it in place. Simultaneously, during the contact between the arc-shaped plates 43 and the pipe fitting surface, the baffle 41 moves with the mounting rod 42, with one end of the baffle 41 contacting the pipe fitting first. As the mounting rod 42 continues to move, the spring 47 is compressed. In use, the baffle 41 can be moved to a suitable height by moving the support plate 46, ensuring the baffle 41 is positioned appropriately against the top surface of the pipe fitting. The pipe is then fixed by inserting the fixing pin 45 into the support plate 46 and the mounting rod 42. If the pipe needs to be rotated, the first threaded rod 32 can be rotated to move the slider 35 and the lifting frame 36 upward, so that the lifting frame 36 contacts the pipe. Then, the second threaded rod 44 is rotated slightly to separate the arc plate 43 from the pipe. At the same time, the baffle 41 is still in contact with the pipe through the action of the spring 47. Thus, the pipe can be adjusted by rotating the pipe. During the process of spraying magnetic powder, the falling magnetic powder will fall into the mounting frame 34 and slide into the receiving trough 33. When the test is over, the receiving trough 33 can be pulled out to recover the magnetic powder.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
