Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of probe fixing jigs, and particularly relates to a reinforced magnetic probe jig. Background Art
[0002] In various industrial ultrasonic detection and monitoring processes, the fixing method of the sensor probe is crucial for the accuracy and stability of the detection results. At present, the common probe fixing methods mainly include hand-held, pasting, mechanical fixing, and magnetic attraction, etc., but these methods have some problems and deficiencies in practical applications.
[0003] The hand-held method is the most direct method, but this method has high requirements for the operation skills and stability of the detection personnel. Long-term detection is easy to cause fatigue, resulting in unstable detection results. In addition, the hand-held method is difficult to implement in some special environments (such as high temperature, high humidity, high pressure, etc.).
[0004] The key to the pasting method is that the selection of the pasting material and the stability of the pasting position directly affect the detection results. After long-term use, the pasting material may age and fall off, causing the sensor probe to loosen and the detection data to be inaccurate.
[0005] The mechanical fixing method usually fixes the sensor probe on the surface of the object to be measured through bolts, jigs, etc. The fixing effect is good, but the installation and disassembly are relatively cumbersome, especially in a narrow or complex environment, the operation difficulty is large.
[0006] The magnetic attraction method is a method that has been gradually widely adopted in recent years. It avoids many problems brought by other methods, but when the surface of the object to be measured is a curved surface, there is a situation where the magnetic probe cannot fully contact the surface of the object to be measured, and when the surface of the object to be measured is a non-metallic material, the magnetic attraction method is not applicable. Content of the Utility Model
[0007] In view of the deficiencies in the background art, the utility model proposes a reinforced magnetic probe jig, which can fix the sensor probe more stably, conveniently and flexibly. The jig has a simple design structure, is easy to install and disassemble, not only improves the fixing reliability of the sensor probe, but also reduces the workload of the detection personnel and improves the accuracy and efficiency of the detection.
[0008] The technical solution for achieving the purpose of the utility model is as follows:
[0009] A reinforced magnetic probe fixture, comprising a square base and a cylindrical base. Perforations are provided on all four sides of the square base, and a probe fixing groove is provided inside the cylindrical base. The square base and the cylindrical base are an integral whole with a circular perforation in the middle. The cylindrical base is provided with an annular protruding part centered on the center of the inner upper surface. A rubidium magnet is fixed at the bottom of the cylindrical base, which can adsorb the entire fixing fixture on the surface of the object to be measured. A fixing rod passes through the circular perforation and is connected to a boss in the probe fixing groove. A spring is sleeved on the fixing rod, the lower end of the spring is sleeved on the outer side of the upper half of the boss, and the upper end of the spring is embedded inside the protruding part.
[0010] Preferably, the diameter of the circular perforation is the same as the diameter of the fixing rod, facilitating the fixing rod to pass through the circular perforation.
[0011] Preferably, each of the four sides of the square base contains a rectangular perforation. The length of the perforation is slightly smaller than the side length of the square base. A binding strap can pass through two opposite perforations. After being tied and fixed, the probe fixture is fastened to the surface of the object to be measured, thereby fastening the sensor probe. The four corners of the square base are cut into concave right angles to reduce the weight of the fixture.
[0012] Preferably, the cylindrical base is grooved on the cylindrical side. There are a total of 4 grooves, which are symmetrically distributed. Each groove occupies 1 / 8 of the circumferential plane where it is located, that is, the central angle is 45°. The protruding part is 2 mm thick, 5 mm high, and the diameter is slightly larger than the diameter of the spring, which is used for fixing when the spring is nested.
[0013] Preferably, the boss is formed by stacking two cylinders with different diameters after processing a cylinder. The diameter of the upper half is slightly smaller than that of the spring, facilitating the spring to be sleeved on the upper half of the boss. The diameter of the lower half is the same as the diameter of the inner probe fixing groove of the cylindrical base, so as to slide up and down in the inner probe fixing groove of the cylindrical base.
[0014] Preferably, the fixing rod passes through the circular perforation of the base and is threadedly connected to the upper half of the boss. A cylindrical component with a diamond-shaped anti-slip pattern is fixed at the top of the fixing rod. The diameter of the cylindrical component is larger than the diameter of the fixing rod and is located above the square base.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] (1) Dual fixation: It has two fixation methods, magnetic attraction and mechanical fixation. By using a strong magnet and a binding strap, it ensures that the sensor probe can be firmly fixed on the surface of the object to be measured, avoiding the displacement and loosening of the sensor probe during the detection process, and ensuring the accuracy and stability of the detection result;
[0017] (2) Wide application range: The fixture design of the present utility model can adapt to the surfaces of measured objects with different shapes and materials. Whether it is a plane or a curved surface, whether it is a metal material or a non-metal material, it can effectively fix the sensor probe, expanding the application range;
[0018] (3) Improve work efficiency: By using this fixture, the detector does not need to hold the sensor for a long time during detection, reducing labor intensity and fatigue, and improving the detection efficiency. At the same time, the stability of the fixed fixture makes the detection results more reliable, reducing detection errors caused by operational mistakes. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0023] See Figures 1 to 3 As shown in the figure, a reinforced magnetic adsorption type probe fixture in this embodiment includes a base. The base includes two upper and lower parts. The upper part is a square base 101 with perforations on all four sides, and the lower part is a cylindrical base 102 with a probe fixing groove inside. A boss 203, a spring 202, and a fixing rod 201 are successively arranged from bottom to top in the middle of the groove body.
[0024] The square base 101 and the cylindrical base 102 are an integral body with a circular perforation in the middle, and the diameter is the same as that of the fixing rod 201.
[0025] Each of the four sides of the square base 101 contains a rectangular perforation, and the length of the perforation is slightly less than the side length of the square base.
[0026] The cylindrical base 102 is grooved on its cylindrical side. There are a total of 4 grooves, which are symmetrically distributed. Each groove occupies 45° of the circumferential plane where it is located. With the center of the inner upper surface as the center of the circle, there is a raised part 1021 with a thickness of 2 mm, a height of 5 mm, and a diameter slightly larger than that of the spring 202. A strong rubidium magnet is embedded at the bottom of the cylindrical base 102 and fixed by screws.
[0027] The boss 203 is cylindrical. The diameter of the upper half is slightly smaller than that of the spring 202, and the diameter of the lower half is the same as the inner diameter of the cylindrical base 102.
[0028] The fixing rod 201 passes through the through hole of the base and is threadedly connected to the upper half of the boss 203. The top end of the fixing rod 201 is a cylinder with a diameter much larger than that of the fixing rod 201, and there is a diamond-shaped anti-slip pattern design, which is convenient for the installation and use of the fixing rod 201.
[0029] The spring 202 is nested on the fixing rod 201. One end facing down is nested on the upper half of the boss 203, and the end facing up is nested on the raised part of the inner upper surface of the cylindrical base 102.
[0030] When in use, the upper end of the spring 202 is stuck in the middle of the raised part of the inner upper surface of the cylindrical base 102 to prevent the upper end of the spring from moving when the fixture is used. The lower end is nested on the upper half of the boss 203 to prevent the lower end of the spring from moving when the fixture is used. Then the fixing rod 201 is passed through the perforation between the square base 101 and the cylindrical base 102 and threadedly connected to the upper half of the boss 203. The sensor probe to be fixed is pressed against the boss 203 and placed in the sensor probe fixing groove inside the cylindrical base 102. The sensor connecting wire is routed through the groove on the side of the cylindrical base 102.
[0031] After cleaning the surface of the object to be measured, place the reinforceable magnetic adsorption type probe fixture on the surface of the object to be measured, and then gently press the fixture to ensure that the strong rubidium magnet at the bottom of the fixture is completely adsorbed on the surface of the object to be measured. The sensor probe is in full contact with the surface of the object to be measured. Finally, pass a tie strap with a length similar to the perforation length of the four sides of the square base 101 through the opposite perforations, bypass the surface of the object to be measured, and tie the two ends of the tie strap to achieve the function of secondary fixation.
[0032] When the surface of the object to be measured is a non-metallic material, first hold the fixture manually, and then fix it through the tie strap.
[0033] In summary, the present invention provides a more stable, convenient and flexible sensor probe fixing solution, overcomes the deficiencies in the prior art, and has broad application prospects and practical value.
[0034] The above embodiments are only used to illustrate the technical concept and features of the present utility model. The purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model.
