An adjustment component 4 is arranged on the top of the workbench 1, and multiple groups of adjustment components 4 are provided. Through the adjustment component 4, it is convenient to adjust the positions of multiple groups of testers 2, so that it is convenient for the staff to use different testers 2 to detect the ultrasonic transducer. The tester 2 can be installed and disassembled on the adjustment component 4, and multiple groups of testers 2 are provided. By moving the tester 2 to the front end of the top of the workbench 1, it is convenient for the staff to use the tester 2. A clamping component 3 is arranged on the top of the workbench 1. Through the clamping component 3, it is convenient for the staff to install or disassemble the ultrasonic transducer, so as to detect ultrasonic transducers of different sizes.
[0034] Refer to Figure 1 and Figure 2 , The clamping component 3 includes a movable plate 32. An arc-shaped plate A33 is fixedly connected to the top of the movable plate 32. The clamping surfaces of the arc-shaped plate A33 and the arc-shaped plate B34 are both rubber surfaces. An arc-shaped plate B34 is slidably connected to the left inner wall of the top of the movable plate 32. Through the sliding effect of the arc-shaped plate B34, the arc-shaped plate B34 and the arc-shaped plate A33 clamp and fix the ultrasonic transducer, or release the fixing effect. A hinge rod 35 is hinged to the front of the arc-shaped plate B34. Through the moving effect of the hinge rod 35, the arc-shaped plate B34 is driven to slide. The right end of the hinge rod 35 is hinged to a slider 36. A limiting component 37 is arranged on the inner wall of the top of the slider 36. Through the limiting component 37, the slider 36 is limited, so that the arc-shaped plate B34 remains fixed.
[0035] Refer to Figure 1 and Figure 3 , The adjustment component 4 includes a sliding plate 41. An L-shaped block 42 is fixedly connected to the left side of the sliding plate 41. Through the fixing effect of the L-shaped block 42, the L-shaped block 42 is prevented from falling off. A fixed frame 45 is fixedly connected to the top of the workbench 1. Through the fixing effect of the fixed frame 45, the fixed frame 45 is prevented from falling off. A chute 47 is opened on the top of the workbench 1.
[0036] Refer to Figure 2The outer wall of the movable plate 32 is slidably connected to the inner wall of the top front end of the workbench 1. The ultrasonic transducer is driven to move by the sliding effect of the movable plate 32. The top front end of the movable plate 32 is fixedly connected with the fixed plate 31. The fixing effect of the fixed plate 31 prevents the fixed plate 31 from falling off. A cylindrical groove 373 is opened on the top of the fixed plate 31. There are multiple groups of cylindrical grooves 373. The multiple groups of cylindrical grooves 373 and cylindrical blocks 374 are used to perform clamping effects at different positions, thereby limiting the slider 36 at different positions. The outer periphery of the slider 36 is slidably connected to the inner wall of the fixed plate 31. The sliding effect of the slider 36 drives the hinged rod 35 to move.
[0037] Reference Figure 2 and Figure 5 The limiting assembly 37 includes a bolt 371, and a threaded hole 372 is opened on the inner wall of the top front end of the workbench 1. There are multiple groups of threaded holes 372. The multiple groups of threaded holes 372 are connected to the bolts 371 at different positions, so as to limit the movable plate 32 at different positions. The top inner wall of the slider 36 is elastically connected with a cylindrical block 374 through a limiting spring 375. Through the elastic force of the limiting spring 375, the cylindrical block 374 always maintains a clamping effect with the cylindrical groove 373 when not affected by external force, thereby limiting the slider 36.
[0038] Reference Figure 3 and Figure 4 The outer wall of the slide plate 41 is slidably connected to the inner wall of the slide groove 47. The sliding effect of the slide plate 41 drives the tester 2 to move. The top of the slide plate 41 contacts the bottom of the tester 2. The L-shaped block 42 is slidably connected to the inner wall of the top rear end of the workbench 1. The sliding effect of the L-shaped block 42 drives the slide plate 41 to slide. The left inner wall of the L-shaped block 42 is elastically connected with a clamping block 44 through a spring 43. Through the elastic force of the spring 43, the clamping block 44 always maintains the clamping effect with the clamping groove 46 without being affected by external force, thereby limiting the L-shaped block 42. A clamping groove 46 is opened on the left side of the fixed frame 45. The clamping groove 46 is symmetrically arranged in two groups. The two groups of clamping grooves 46 are used to perform clamping effects with the clamping block 44 at different positions, thereby performing limiting effects on the L-shaped block 42 at different positions. The outer wall of the L-shaped block 42 is slidably connected to the inner wall of the fixed frame 45.
[0039] Reference Figure 2 and Figure 5The outer wall of the bolt 371 is threadedly connected to the inner wall of the top right end of the movable plate 32. By screwing the bolt 371, the bolt 371 and the threaded hole 372 are threadedly connected or released, thereby limiting or releasing the limiting effect of the movable plate 32. One end of the limiting spring 375 is fixedly connected to the top inner wall of the slider 36, and the other end of the limiting spring 375 is fixedly connected to the bottom of the cylindrical block 374. The fixing effect of the limiting spring 375 keeps the cylindrical block 374 fixed to prevent the cylindrical block 374 from falling off.
[0040] Reference Figure 3 One end of the spring 43 is fixedly connected to the left inner wall of the L-shaped block 42, and the other end of the spring 43 is fixedly connected to the outer wall of the card block 44. The fixing effect of the spring 43 keeps the card block 44 fixed to prevent the card block 44 from falling off. The outer wall of the card block 44 is slidably connected to the left inner wall of the L-shaped block 42. The sliding effect of the card block 44 allows the card block 44 to be engaged or released from the card slot 46. The outer wall of the card block 44 is engaged with the inner wall of the card slot 46. The engagement effect of the card block 44 and the card slot 46 allows the fixed frame 45 to limit the L-shaped block 42.
[0041] Reference Figure 1 and Figure 5 The outer wall of the bolt 371 is threadedly connected to the inner wall of the threaded hole 372, and the outer wall of the cylindrical block 374 is slidably connected to the top inner wall of the slider 36. Through the sliding effect of the cylindrical block 374, the cylindrical block 374 and the cylindrical groove 373 are engaged or released. The outer wall of the cylindrical block 374 is engaged with the inner wall of the cylindrical groove 373. Through the engaging effect of the cylindrical block 374 and the cylindrical groove 373, the fixed plate 31 limits the slider 36.
[0042] Working principle: When the staff needs to test the ultrasonic transducer, the staff places the ultrasonic transducer on the movable plate 32 and between the arc plate A33 and the arc plate B34. By pressing the cylindrical block 374, the cylindrical block 374 is released from the clamping effect with the cylindrical groove 373, and the limiting effect on the slider 36 is released. The slider 36 is slid to the left, so that the hinge rod 35 drives the arc plate B34 to slide toward the back of the movable plate 32, and the ultrasonic transducer is clamped and fixed by the arc plate B34 and the arc plate A33. The cylindrical block 374 is released, so that the cylindrical block 374 is clamped with the cylindrical groove 373 under the elastic force of the limiting spring 375, thereby limiting the slider 36 and keeping the arc plate B34 in a fixed clamping state.
[0043] The staff presses the block 44 to release the clamping effect of the block 44 on the clamping slot 46 and release the limiting effect on the L-shaped block 42. The L-shaped block 42 is slid toward the front of the workbench 1, thereby driving the slide plate 41 to slide toward the front of the workbench 1 along the inner wall of the slide slot 47, so that the tester 2 moves to the top front end of the workbench 1. The block 44 is released, so that the block 44 is clamped with the clamping slot 46 under the elastic force of the spring 43, and the L-shaped block 42 is limited, so that the slide plate 41 remains fixed. The staff loosens the bolt 371 to release the limiting effect on the movable plate 32, and moves the movable plate 32 to the position of the tester 2 of the item to be tested. The bolt 371 is tightened to keep the movable plate 32 fixed, which is convenient for the staff to perform testing. Through the same operation as above, it is convenient to perform comprehensive testing of various items on the ultrasonic transducer.
[0044] When it is necessary to test ultrasonic transducers of different sizes, the limiting effect of the slider 36 is released and the slider 36 is slid to the right, so that the hinge rod 35 drives the arc plate B34 to slide toward the front of the movable plate 32, thereby releasing the clamping and fixing effect of the ultrasonic transducer, thereby facilitating the staff to replace the ultrasonic transducer.
[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
