Technical Field

[0001] The utility model relates to the technical field of workpiece detection fixtures, and particularly relates to a detection fixture for metal product processing. Background Art

[0002] Metal products refer to various products mainly made of metal materials and processed, including but not limited to structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily metal products, etc.

[0003] During the production and manufacturing of metals, to ensure the quality of metal products, it is generally necessary to detect problems such as cracks, porosity, air holes, and inclusions in the manufactured metal workpieces. The existing detection method is to use an ultrasonic flaw detector and move the probe on the surface of the workpiece to achieve non-destructive detection. However, since the ultrasonic waves appearing on the display screen of the detector need to be observed while moving the probe, it is impossible to always ensure the positional relationship between the probe and the workpiece during the pressure application and movement operation, resulting in the phenomenon that the position between the probe and the workpiece is prone to deviation during the movement, thus affecting the detection result and being not conducive to use. Summary of the Utility Model

[0004] Based on the above description, the utility model provides a detection fixture for metal product processing to solve the problem that the traditional non-destructive detection operation method is prone to probe deviation and affects the detection result.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A detection fixture for metal product processing includes a detection table, an ultrasonic detector, and a metal workpiece. A workpiece limiting groove and several slots are opened on the surface of the detection table. A fixing plate is arranged on the surface of the detection table. Several through holes and several jacks are opened on the surface of the fixing plate. Several first limiting plates, a convex rod is arranged on the surface of the first limiting plate, a threaded rod is arranged on the surface of the first limiting plate, and a nut is arranged on the outer side of the threaded rod. Several springs are respectively located in several through holes. Several second limiting plates, and a connecting plate is arranged on the surface of the second limiting plate.

[0006] On the basis of the above technical solution, the utility model can be further improved as follows.

[0007] Further, the convex rod is designed in an "L" shape, and the end of the convex rod away from the first limiting plate is designed as a semi-circle. The surfaces of the fixing plate and the convex rod are both smooth surfaces.

[0008] Further, a rubber gasket is arranged on one side of the first limiting plate, and the side of the rubber gasket away from the first limiting plate is in close contact with the surface of the fixing plate.

[0009] Further, the first limiting plate is designed with a plastic material, and a cavity is provided inside the first limiting plate, and a first handle is provided on the surface of the first limiting plate.

[0010] Further, a first opening, a second opening, and a third opening are respectively formed on the surface of the first limiting plate.

[0011] Further, a first rubber plug, a second rubber plug, and a third rubber plug are respectively provided inside the first opening, the second opening, and the third opening.

[0012] Further, one ends of the first rubber plug, the second rubber plug, and the third rubber plug protrude to the outside of the first limiting plate.

[0013] Further, a second handle is provided on the surface of the second limiting plate.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0015] 1. By respectively providing the second limiting plate and the first limiting plate on the detection table and the fixing plate, the limiting effects on the metal workpiece and the ultrasonic detector can be effectively realized by using the second limiting plate and the first limiting plate, so that it is more beneficial for the staff to move the probe part of the ultrasonic detector, avoiding the phenomenon of probe deviation when moving the probe part of the ultrasonic detector and observing the ultrasonic wave at the same time, and the detection result is more accurate.

[0024] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant drawings. Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] This embodiment provides a detection fixture for metal product processing. This detection fixture can achieve a limiting effect on detection probes of different specifications and sizes and is applicable to the detection of metal products of various thicknesses. Specifically, such as Figures 1-5As shown in the figure, it includes a detection table 1, an ultrasonic detector 2, a metal workpiece 3, a fixing plate 4, two first limit plates 5, two springs 7 and two second limit plates 8. The ultrasonic detector 2 includes a probe part and an instrument host part, and the probe part is connected to the instrument host part through a data processing line. The ultrasonic detector 2 is a workpiece internal defect detector of model HY-CT350. A workpiece limit groove 11 and a plurality of slots 12 are formed on the top surface of the detection table 1. The workpiece limit groove 11 is used for placing metal products of different thicknesses. The plurality of slots 12 are divided into two groups, and each group of slots 12 is respectively formed on the top surface of the detection table 1 and near the left and right sides of the workpiece limit groove 11. The fixing plate 4 is vertically fixedly connected to the top surface of the detection table 1 and near the back position. Two through holes 41 and a plurality of jacks 42 are formed on the surface of the fixing plate 4. The plurality of jacks 42 are divided into two groups, and each group of jacks 42 is respectively arranged at equal intervals along a circular shape on the front surface of the fixing plate 4 and near the outside of the through hole 41. A convex rod 51 is fixedly connected to the surface of the first limit plate 5. The convex rod 51 is designed in an "L" shape. One end of the convex rod 51 away from the first limit plate 5 protrudes into the jack 42. A threaded rod 52 is horizontally and longitudinally fixedly connected to the back surface of the first limit plate 5. The threaded rod 52 is located in the through hole 41. A nut 6 is threadedly connected to the outside of the threaded rod 52. The two springs 7 are respectively located between the two fixing plates 4 and the nut 6 through the two through holes 41. The springs 7 are in a compressed state and are in close contact with the surfaces of the fixing plate 4 and the nut 6 respectively. A connecting plate 81 is integrally formed on the surface of the second limit plate 8. A second handle 82 is provided on the surface of the second limit plate 8 to facilitate the position adjustment between the second limit plate 8 and the detection table 1. The front view shape between the second limit plate 8 and the connecting plate 81 is designed in a "T" shape. The connecting plate 81 is movably inserted into the slot 12, so that the probe part of the ultrasonic detector 2 can be limited between the two first limit plates 5, and the metal workpiece 3 of corresponding thickness is limited between the two second limit plates 8, so that the probe part of the ultrasonic detector 2 can always be on the surface of the metal workpiece 3, avoiding the phenomenon of deviation during the sliding detection process.

[0027] As Figure 4 shown, in this embodiment, one end of the convex rod 51 away from the first limit plate 5 is designed in a semi-circular structure, and the surfaces of the fixing plate 4 and the convex rod 51 are both smooth surfaces, which makes it more beneficial for the staff to insert the convex rod 51 into the jack 42 when rotating and adjusting the first limit plate 5, and the adjustment operation of the first limit plate 5 is more convenient.

[0028] As Figure 4As shown, in this embodiment, a rubber washer 9 is adhesively fixed at the back of the first limiting plate 5 and near the outer side. The side of the rubber washer 9 away from the first limiting plate 5 is in close contact with the surface of the fixing plate 4. The first limiting plate 5 is designed with a plastic material and has a cavity inside, making the overall mass of the first limiting plate 5 lighter and more convenient for adjustment. A first handle 53 is provided on the surface of the first limiting plate 5, enabling the staff to hold the first handle 53 to exert an outward pressure on the first limiting plate 5 and rotate it for adjustment, thereby effectively using the rubber washer 9 to achieve the protective effect on the first limiting plate 5 and avoiding the situation that when the convex rod 51 corresponds to the jack 42 and the spring 7 in the compressed state rebounds suddenly, the first limiting plate 5 and the fixing plate 4 collide with each other during contact and cause accidental damage.

[0029] As Figure 1 and Figure 4 shown, in this embodiment, an opening one 54, an opening two 55 and an opening three 56 are respectively formed on the surface of the first limiting plate 5. The opening one 54, the opening two 55 and the opening three 56 are all in a through state with the cavity formed in the first limiting plate 5. The diameters of the opening one 54, the opening two 55 and the opening three 56 are adapted to the specifications of the respective probes. Rubber plugs one 101, rubber plugs two 102 and rubber plugs three 103 are respectively provided inside the opening one 54, the opening two 55 and the opening three 56. One ends of the rubber plugs one 101, rubber plugs two 102 and rubber plugs three 103 protrude to the outside of the first limiting plate 5, so that the respective probes of each specification can be restricted and stored by using the opening one 54, the opening two 55 and the opening three 56 respectively, which is convenient for reusing the stored probes. At the same time, by providing the rubber plugs one 101, rubber plugs two 102 and rubber plugs three 103, the temporary closing effects on the opening one 54, the opening two 55 and the opening three 56 can be respectively achieved, avoiding external sundries from falling into the first limiting plate 5 through the opening one 54, the opening two 55 and the opening three 56 and being unfavorable for storing the probe part.

[0030] During the use of the above metal product detection fixture, the staff can select the corresponding probe part of the ultrasonic detector 2 according to the thickness of the metal workpiece 3 to be detected and install it. Then, hold the handle 53 of the first limiting plate 5 and pull it, so that the spring 7 in the through hole 41 is continuously compressed under the extrusion force of the nut 6, and the convex rod 51 is away from the jack 42. Then, rotate the first limiting plate 5 so that the distance between the two first limiting plates 5 corresponds to the size of the corresponding probe part. Then, release the handle 53, and the spring 7 rebounds, and the convex rod 51 is inserted into another jack 42. Then, the staff can hold the handle 82 of the second limiting plate 8 and lift the second limiting plate 8 upward to separate the connecting plate 81 from the slot 12, and adjust the position distance between the two second limiting plates 8. After adjusting the position distance, insert the connecting plate 81 into the slot 12 again to complete the position adjustment of the second limiting plate 8. Finally, the staff can insert the metal workpiece 3 to be detected between the two second limiting plates 8, so that a part of the surface of the metal workpiece 3 is located directly below the two first limiting plates 5. Finally, the staff can hold the probe part of the ultrasonic detector 2 and detect the metal workpiece 3 along between the two first limiting plates 5 to avoid the deviation of the probe.

[0031] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
