Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardness tester technology, and in particular to a magnetically attracted fixed-point ultrasonic hardness tester. Background Technology
[0002] An ultrasonic hardness tester is a portable instrument that utilizes the correlation between the propagation characteristics of ultrasonic pulses in materials and the material's hardness. By measuring these parameters and converting them using a built-in algorithm, it can quickly and non-destructively determine the hardness of materials.
[0003] However, traditional ultrasonic hardness testers rely on manual holding to keep the probe perpendicular to the test point, which makes it difficult to ensure the accuracy and stability of the measurement. Even with a simple stand, the probe is easily moved by external forces or vibrations during the measurement process. Moreover, the position of the stand and the ultrasonic hardness tester must be readjusted every time the test point is changed, which is cumbersome and inefficient. In addition, the process of assembling and disassembling the ultrasonic hardness tester on the stand is complicated, which is not conducive to the operator quickly responding to test points that are inconvenient to measure. Utility Model Content
[0004] The purpose of this invention is to provide a magnetically attached, fixed-point ultrasonic hardness tester to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes a magnetic base, a placement seat is provided on one side of the magnetic base, a vertical adjustment component is provided on the magnetic base, a horizontal adjustment component is provided on one side of the vertical adjustment component, a clamping component is provided on the horizontal adjustment component, and an ultrasonic hardness tester is provided inside the clamping component.
[0006] As a preferred embodiment of this utility model, the vertical adjustment component includes a support frame disposed on a magnetic base, a fixing sleeve disposed on the magnetic base, a lead screw inserted inside the fixing sleeve, and a motor disposed on the top of the support frame corresponding to the position of the fixing sleeve, the transmission end of the motor being connected to one end of the lead screw.
[0007] As a preferred embodiment of this utility model, a driving block is helically sleeved on the outer side of the lead screw, and a pair of lifting guide rails are symmetrically arranged on both sides of the support frame, with the driving block slidably mounted on the lifting guide rails.
[0008] As a preferred embodiment of this utility model, the horizontal adjustment component includes a mounting box disposed on one side of the drive block, a second motor disposed inside the mounting box, a gear disposed on the transmission end of the second motor, and a rack meshing with one side of the gear.
[0009] As a preferred embodiment of this utility model, the mounting box is provided with a movable guide rail, the rack is slidably mounted on the movable guide rail, and the mounting box is provided with a protective plate.
[0010] As a preferred embodiment of the present invention, the clamping assembly includes a connecting frame disposed on a rack, a mounting plate disposed at the end of the connecting frame away from the rack, a pair of telescopic cylinders symmetrically disposed on both sides of the mounting plate, and a V-shaped clamping seat disposed at the top of the telescopic rods of the two telescopic cylinders.
[0011] As a preferred embodiment of this invention, the ultrasonic hardness tester includes a handheld PDA and a CUI measuring probe, wherein the handheld PDA is located in the placement base and the CUI measuring probe is located between V-shaped clamps.
[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0013] 1. This utility model, by setting up a vertical adjustment component, uses a motor to drive the lead screw to rotate, converting the rotational motion of the lead screw into the linear motion of the drive block, and relies on the lifting guide rail to ensure the stability of the drive block during movement. This enables the ultrasonic hardness tester to perform precise and stable position adjustment in the vertical direction, which not only improves the accuracy of measurement, but also enhances the adaptability and flexibility of the device, and can adapt to the measurement needs of different heights.
[0014] 2. This utility model, by setting up a horizontal adjustment component, uses a motor to drive the gear to rotate. Through the meshing relationship between the gear and the rack, the rack moves horizontally along the moving guide rail, ensuring that the ultrasonic hardness tester is accurately positioned in the horizontal direction and that the movement process is smooth and without shaking. This improves the stability and accuracy of the measurement, meets the need for sequential measurement of multiple test points, and eliminates the need for frequent movement of the entire device.
[0015] 3. This utility model, by setting up a clamping assembly, uses the telescopic rod of the telescopic cylinder to drive the V-shaped clamping seat to clamp or release the CUI measuring probe of the ultrasonic hardness tester. This not only ensures the stability of the CUI measuring probe during measurement, but also allows operators to quickly remove the CUI measuring probe when encountering inconvenient test points and hold it with both hands for measurement, thus improving work efficiency. In addition, the V-shaped clamping seat can adapt to CUI measuring probes of different sizes, enhancing the versatility and practicality of the overall device.
[0016] 4. This utility model, by setting up a magnetic base and a placement seat, allows the magnetic base to quickly and firmly fix the ultrasonic hardness tester to the metal test surface with its strong and stable adsorption capacity, realizing fixed-point measurement, effectively resisting external interference and vibration, providing reliable support for hardness measurement, and ensuring accurate and stable measurement. At the same time, the placement seat provides storage space for the handheld PDA, which not only properly places it to avoid damage or loss, but also makes it convenient for operators to access and place it at any time, ensuring a smooth and efficient measurement process.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] like Figures 1-4 As shown, the present invention proposes a magnetically attached fixed-point ultrasonic hardness tester, which includes a magnetic base 1. The magnetic base 1 provides a stable adsorption force, so that the whole device can be firmly fixed on the metal test surface. A placement seat 2 is provided on one side of the magnetic base 1. The placement seat 2 is used to place the handheld PDA of the ultrasonic hardness tester 6. A vertical adjustment component 3 is provided on the magnetic base 1. A horizontal adjustment component 4 is provided on one side of the vertical adjustment component 3. A clamping component 5 is provided on the horizontal adjustment component 4. The ultrasonic hardness tester 6 is placed inside the clamping component 5.
[0024] The vertical adjustment assembly 3 includes a support frame 31 mounted on the magnetic base 1. The support frame 31 provides an installation base for other components in the vertical adjustment assembly 3. A fixing sleeve 32 is mounted on the magnetic base 1. A lead screw 33 is inserted into the fixing sleeve 32. The fixing sleeve 32 provides support for the lead screw 33 to ensure the stability of the lead screw 33 during rotation. A motor 34 is mounted on the top of the support frame 31 at a position corresponding to the fixing sleeve 32. The transmission end of the motor 34 is connected to one end of the lead screw 33. The motor 34 provides rotational power to the lead screw 33, converting the rotational motion of the lead screw 33 into the linear motion of the drive block 35.
[0025] A drive block 35 is helically sleeved on the outside of the lead screw 33. The drive block 35 provides an installation base for the horizontal adjustment component 4. A pair of lifting guide rails 36 are symmetrically arranged on both sides of the support frame 31. The drive block 35 is slidably mounted on the lifting guide rails 36. The lifting guide rails 36 provide guidance for the drive block 35 and ensure the stability of the drive block 35 when it moves.
[0026] The horizontal adjustment assembly 4 includes a mounting box 41 disposed on one side of the drive block 35. The mounting box 41 provides a mounting base for other components in the horizontal adjustment assembly 4. A second motor 42 is disposed inside the mounting box 41. A gear 43 is disposed on the transmission end of the second motor 42. The second motor 42 provides rotational power to the gear 43. A rack 44 is meshed on one side of the gear 43. The rotation of the gear 43 transmits power to the rack 44 through meshing, thereby driving the rack 44 to move.
[0027] The mounting box 41 is equipped with a movable guide rail 45, and the rack 44 is slidably mounted on the movable guide rail 45. The movable guide rail 45 provides guidance for the rack 44 and ensures the stability of the rack 44 when it moves. The mounting box 41 is equipped with a protective plate 46, which protects the internal components of the mounting box 41 from external environmental interference.
[0028] The clamping assembly 5 includes a connecting frame 51 mounted on the rack 44. A mounting plate 52 is provided at the end of the connecting frame 51 away from the rack 44. The connecting frame 51 connects the mounting plate 52 and the rack 44. When the rack 44 moves, it drives the mounting plate 52 to move. A pair of telescopic cylinders 53 are symmetrically arranged on both sides of the mounting plate 52. A V-shaped clamping seat 54 is provided at the top of the telescopic rod of each telescopic cylinder 53. The extension and retraction of the telescopic rod of the telescopic cylinder 53 can drive the two V-shaped clamping seats 54 to clamp or release the CUI measuring probe of the ultrasonic hardness tester 6.
[0029] The ultrasonic hardness tester 6 includes a handheld PDA and a CUI measuring probe. The handheld PDA is located in the placement base 2 and is used to control and display measurement data. The CUI measuring probe is located between the V-shaped clamps 54 and is used to actually measure the hardness of the material.
[0030] In use, the operator first attaches the magnetic base 1 to the metal surface to be tested, ensuring the device is stable and fixed. Then, the handheld PDA of the ultrasonic hardness tester 6 is placed in the placement seat 2, and the CUI measuring probe is placed between the two V-shaped clamps 54. The telescopic cylinder 53 then extends its telescopic rod, driving the two V-shaped clamps 54 to move closer together and clamp the CUI measuring probe, ensuring stability during hardness measurement. Next, the motor 34 of the vertical adjustment component 3 drives the lead screw 33 to rotate, converting the rotational motion of the lead screw 33 into the linear motion of the drive block 35. This causes the drive block 35 and the horizontal adjustment component 4 to rise and fall along the lifting guide rail 36, adjusting the CUI measuring probe of the ultrasonic hardness tester 6. The vertical position is then adjusted. Next, the motor 42 of the horizontal adjustment component 4 drives the gear 43 to rotate. The gear 43 transmits power to the rack 44 through meshing, causing the rack 44 to move horizontally along the moving guide rail 45. This further adjusts the horizontal position of the CUI measuring probe, allowing the CUI measuring probe to be aligned with multiple test points in sequence. Then, hardness measurement begins. The handheld PDA displays the measurement results. When encountering test points that are inconvenient to measure, the operator can retract the telescopic rod of the telescopic cylinder 53 in the clamping component 5, causing the two V-shaped clamping seats 54 to move away from each other and release the CUI measuring probe. The operator can then perform the measurement by holding the probe with both hands, achieving accurate positioning and stable measurement of the ultrasonic hardness tester 6.
