Description

Technical Field

[0001] The utility model relates to the technical field of testers, and in particular to a probe tester. Background Art

[0002] An ultrasonic probe tester is a device used to detect and evaluate structural defects or features within materials or objects. To ensure accurate measurement, a test block is often added to the tester. Calibration and verification of the tester's accuracy is performed by measuring the top and bottom surfaces of the test block.

[0003] In order to facilitate the rotation of the test block, existing probe testers are often equipped with a ratchet mechanism. The test block rack is flipped by turning the crank, thereby achieving the purpose of quickly measuring both sides of the test block.

[0004] Although this can achieve double-sided measurement of the test block, the following problems still exist: the test block cannot be rotated accurately to 180°, resulting in the actual rotation angle being greater than 180 degrees or less than 180°, making the test surface of the test block not in a horizontal state, affecting the test result of the test block. Utility Model Content

[0005] The utility model provides a probe tester, which solves the problem in the prior art that the test block is difficult to accurately rotate to 180 degrees, thereby improving the practicability of the equipment.

[0006] The technical solution of the utility model is as follows:

[0008] A first sliding groove is provided at the lower end of the shell, and a box body is slidingly connected in the first sliding groove. A placement groove is provided on the top of the box body, and a mounting piece is rotatably connected to the side wall of the placement groove. A test block is detachably connected to the mounting piece, and a control structure for controlling the test block to rotate 180° is provided between the mounting piece and the box body.

[0009] Furthermore, the control structure includes a sliding rail fixedly arranged on the inner wall of the box body, a second sliding groove is provided in the sliding rail, the cross-section of the second sliding groove is a "convex" structure, a sliding member is slidingly connected to the second sliding groove, a plurality of connecting members are fixed on the sliding member, a first rotating shaft and a second rotating shaft are respectively fixed on both sides of the mounting member, the box body is rotatably connected to the first rotating shaft and the second rotating shaft at the same time, a rotating member is fixed on the first rotating shaft, a plurality of convex teeth are provided on the side wall of the rotating member, and the connecting member is engaged with the convex teeth.

[0010] Further, the rotating member is of a cylindrical structure. A first limiting portion is fixed to the top of the rotating member. A first limiting surface is provided on the top of the first limiting portion. A second limiting portion is fixed to the bottom of the rotating member. A second limiting surface is provided on the bottom of the second limiting portion. A first limiting plate and a second limiting plate are fixed to the sliding member. Each rotating member is disposed between the first limiting plate and the second limiting plate. Each convex tooth is between the first limiting portion and the second limiting portion. The first limiting surface abuts against the first limiting plate. The shortest distance from the first limiting surface to the center of the rotating member is equal to the shortest distance from the second limiting surface to the center of the connecting plate. The horizontal heights of the first limiting plate and the second limiting plate are the same.

[0011] Further, there is a gap between the first limiting plate and each connecting member, and there is a gap between the second limiting plate and each connecting member.

[0012] Further, guiding surfaces are provided on the side of the first limiting portion close to the convex tooth and the side of the second limiting portion close to the convex tooth. The guiding surfaces are of an arc-shaped structure.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 2 to 5As shown, this embodiment proposes a probe tester, the structure of which includes a shell 1. The first sliding groove 11 in this embodiment is set at the lower end of the shell 1, the box 2 is slidably set in the first sliding groove 11, the top of the box 2 is provided with a placement groove 24, the mounting member 3 is rotatably set on the side wall of the placement groove 24, and the test block 4 is detachably connected to the mounting member 3. A control structure is set between the mounting member 3 and the box 2, and is used to control the test block 4 to rotate 180°. This embodiment adopts a drawer-pull-out type to set the box 2, to ensure that the test block 4 can be stored in the shell 1 when not being tested, to prevent the test block 4 from being affected by the external environment and affecting the test accuracy of the test block 4.

[0028] The control structure in this embodiment includes a sliding rail 8, which is fixedly mounted on the inner wall of the housing 2. A second sliding groove 81 is disposed within the sliding rail 8. The cross-section of the second sliding groove 81 is a "convex"-shaped structure. The sliding member 5 is slidingly mounted on the second sliding groove 81. A plurality of connecting members 6 are fixedly mounted on the sliding member 5. A first rotating shaft 312 and a second rotating shaft 331 are respectively fixedly mounted on opposite sides of the mounting member 3. The housing 2 is simultaneously rotationally connected to the first rotating shaft 312 and the second rotating shaft 331. The rotating member 7 is fixedly mounted on the first rotating shaft 312. A plurality of protruding teeth 73 are disposed on the side walls of the rotating member 7. The connecting members 6 engage with the protruding teeth 73. In this embodiment, the protruding teeth 73 on the rotating member 7 engage with the connecting member 6 to achieve an 80° flip of the rotating member 7, thereby completing the test on both sides of the test block 4 and improving the test accuracy and efficiency.

[0029] The rotating member 7 in this embodiment is a cylindrical structure, which is used to facilitate the installation of the protruding teeth 73 and the rotation of the rotating member 7. The first limiting portion 71 is fixedly arranged at the top of the rotating member 7, and the first limiting surface 711 is arranged at the top of the first limiting portion 71. The second limiting portion 72 is fixedly arranged at the bottom of the rotating member 7, and the second limiting surface 721 is arranged at the bottom of the second limiting portion 72. The sliding member 5 is fixed with a first limiting plate 51 and a second limiting plate 52. Each rotating member 7 is arranged between the first limiting plate 51 and the second limiting plate 52, and each protruding tooth 73 is positioned between the first limiting portion 71 and the second limiting portion 72. The first limiting surface 711 abuts against the first limiting plate 51. The shortest distance from the first limiting surface 711 to the center of the rotating member 7 is equal to the shortest distance from the second limiting surface 721 to the center of the connecting plate. The horizontal height of the first limiting plate 51 and the horizontal height of the second limiting plate 52 are the same. When measuring the top surface of the test block 4, the first limit surface 711 abuts against the first limit plate 51, so that the test block 4 will not rotate during the test; when measuring the bottom surface of the stone, the second limit surface 721 abuts against the second limit plate 52, ensuring that the test block 4 will not rotate when testing the bottom surface, thereby improving the accuracy of measurement and calibration.

[0030] In this embodiment, the guiding surface 712 is provided on the side of the first limiting portion 71 close to the convex tooth 73 and the side of the second limiting portion 72 close to the convex tooth 73. The guiding surface 712 is an arc-shaped structure. The guiding surface 712 is provided to help the convex tooth 73 on the rotating member 7 engage with the connecting member 6, and prevent misalignment between the rotating member 7 and the connecting member 6, which may cause non-engagement.

[0031] In this embodiment, the connecting member 6 is a cylindrical structure, which is convenient for engaging with the convex tooth 73, so that the sliding member 5 will not be stuck when sliding. There is a gap between the first limiting plate 51 and each connecting member 6, and there is a gap between the second limiting plate 52 and each connecting member 6. Such a design not only ensures that the rotating member 7 will not rotate when the first limiting plate 51 abuts against the first abutting surface or the second limiting plate 52 abuts against the second abutting surface, but also enables the rotating member 7 to rotate through the gap when passing through the connecting member 6 from the first limiting plate 51 or the second limiting plate 52, helping the rotating member 7 to transition from the restricted rotation state to the rotation state.

[0032] In this embodiment, the handle 21 is fixedly arranged on the outer surface of the box body 2. The sliding hole 23 is arranged on the box body 2. The control member 22 is slidably arranged in the sliding hole 23, and the control member 22 is fixedly connected to the connecting member 6. The design of the handle 21 in this embodiment is to facilitate the movement of the box body 2 and facilitate the removal of the box body 2 for measuring the test block 4. The design of the control member 22 outside the box body 2 is to facilitate the quick adjustment of the rotation of the test block 4. The user can move the control member 22 to one end of the sliding hole 23 to realize the test of one end or the other end of the test block 4.

[0033] In this embodiment, the mounting member 3 includes a first mounting portion 31 and a second mounting portion 33. The clamping groove 311 is arranged on the side of the first mounting portion 31 close to the second mounting portion 33 and the side of the second mounting portion 33 close to the first mounting portion 31. The cross-section of the clamping groove 311 is a "U" - shaped structure. A number of locking bolts 34 are arranged on the side wall of the clamping groove 311. The test block 4 is inserted into the clamping groove 311 and abuts against the locking bolts 34. The mounting plate 32 is fixedly arranged at the end of the clamping groove 311, which is used to enable the test block 4 to be clamped into the clamping groove 311 and abut against the mounting plate 32 when installing a new test block 4, facilitating the use of the locking bolts 34 for locking and fixing. This is actually to facilitate the quick disassembly and installation of the test block 4 when the test block 4 is worn or damaged.

[0034] In this embodiment, an area for displaying the operation method and calculation formula may be provided on the right side of the operation interface 9, so that the user can directly view the relevant operation method and calculation formula during the operation process, improving the intuitiveness and accuracy of the operation. The operation steps and calculation formula of the current test index are intuitively displayed in the form of images, texts or a combination of images and texts, and the user can operate without referring to other materials.

[0035] The working process of this embodiment is as follows: when the test block 4 needs to be calibrated, first slide the box body 2 out of the shell body 1 through the handle 21, and then measure the top of the test block 4 through the probe. At this time, the first limit plate 51 is in contact with the first limit surface 711, and then move the control member 22, and drive the sliding member 5 to move through the control member 22, so that the rotating member 7 is separated from the first limit plate 51 and rotated through the connecting member 6. Finally, the second limit plate 52 on the rotating member 7 is in contact with the second limit surface 721 to complete the 180° rotation of the test block 4, and then the other side of the test block 4 can be calibrated and measured.

[0036] The above are only 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 principles of the present invention should be included in the scope of protection of the present invention.
