[0020] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0021] Embodiment 1: A testing device for an ultrasonic knife bar, comprising: a bottom plate 1, a vertical plate 2 installed on the upper surface of the bottom plate 1 and extending left and right, and a testing module 18 arranged on the right side of the vertical plate 2, wherein a guide rail 3 extending left and right is installed on the upper surface of the vertical plate 2, a positioning block 5 is arranged on the upper surface of a slider 4 movably installed on the guide rail 3, a clamping block 6 is arranged above the positioning block 5, a groove 7 is provided on the lower surface of the clamping block 6 and the upper surface of the positioning block 5, so that a clamping area 8 is surrounded between the two oppositely arranged grooves 7;

[0022] First, one end of the ultrasonic knife rod is rigidly connected to the transducer, and then the transducer is placed in the clamping area surrounded by the positioning block and the clamping block to clamp the transducer;

[0023] A transducer 101 equipped with an ultrasonic knife rod 102 is embedded and installed in the clamping area 8, and the end of the ultrasonic knife rod 102 opposite to the transducer 101 extends toward the test module 18, and the test module 18 further includes: a laser generator 181 arranged toward the end surface of the right end of the ultrasonic knife rod 102, a receiving screen 182 for receiving reflected light from the end surface of the ultrasonic knife rod 102 and forming a light spot, and a displacement sensor 183 for sensing the change of the light spot position on the receiving screen 182;

[0024] A mounting seat 16 is provided between the test module 18 and the bottom plate 1, and a first horizontal slide 17 and a second horizontal slide 13 are stacked in sequence above the mounting seat 16 whose lower surface is connected to the bottom plate 1, and a movable portion of the first horizontal slide 17 whose fixed portion is mounted on the upper surface of the mounting seat 16 is connected to a fixed portion of the second horizontal slide 13, and the test module 18 is mounted on the movable portion of the second horizontal slide 13;

[0025] When in use, the laser beam emitted by the laser generator irradiates the end face of the ultrasonic knife rod head, and the generated reflected light will be received by the receiving screen to form a light spot. When the ultrasonic knife rod is stationary, the test module is moved in the horizontal direction by adjusting the positions of the first horizontal slide and the second horizontal slide respectively until the light spot reflected by the ultrasonic knife rod can fall on the center of the receiving screen. At this time, the light spot position is set to zero, ensuring that the receiving screen can receive the reflected light spot in the subsequent test process, thereby improving the test accuracy and efficiency.

[0026] The test module 18 is mounted on the movable portion of the second horizontal slide 13 via a support plate 15 .

[0027] A manual adjustment knob 9 is provided on each of the first horizontal slide 17 and the second horizontal slide 13 .

[0028] A locking block 10 is installed on the guide rail 3. A locking knob 11 is provided on the locking block 10 connected to the slider 4 or the positioning block 5. When the locking knob 11 is in a locked state, the locking block 10 is tightly matched with the guide rail 3. When the locking knob 11 is in an unlocked state, the locking block 10 is slidably matched with the guide rail 3.

[0029] When the locking knob is in the locked state, the inner wall of the adjustment slot holds the guide rail tightly. At this time, the position of the slider on the guide rail cannot be adjusted, which can prevent the slider from being displaced during the test.

[0030] Embodiment 2: A testing device for an ultrasonic knife bar, comprising: a bottom plate 1, a vertical plate 2 installed on the upper surface of the bottom plate 1 and extending left and right, and a testing module 18 arranged on the right side of the vertical plate 2, wherein a guide rail 3 extending left and right is installed on the upper surface of the vertical plate 2, a positioning block 5 is arranged on the upper surface of a slider 4 movably installed on the guide rail 3, a clamping block 6 is arranged above the positioning block 5, a groove 7 is provided on the lower surface of the clamping block 6 and the upper surface of the positioning block 5, so that a clamping area 8 is enclosed between the two oppositely arranged grooves 7;

[0031] A transducer 101 equipped with an ultrasonic knife rod 102 is embedded and installed in the clamping area 8, and the end of the ultrasonic knife rod 102 opposite to the transducer 101 extends toward the test module 18, and the test module 18 further includes: a laser generator 181 arranged toward the end surface of the right end of the ultrasonic knife rod 102, a receiving screen 182 for receiving reflected light from the end surface of the ultrasonic knife rod 102 and forming a light spot, and a displacement sensor 183 for sensing the change of the light spot position on the receiving screen 182;

[0032] A mounting seat 16 is provided between the test module 18 and the bottom plate 1, and a first horizontal slide 17 and a second horizontal slide 13 are stacked in sequence above the mounting seat 16 whose lower surface is connected to the bottom plate 1, and a movable portion of the first horizontal slide 17 whose fixed portion is mounted on the upper surface of the mounting seat 16 is connected to a fixed portion of the second horizontal slide 13, and the test module 18 is mounted on the movable portion of the second horizontal slide 13;

[0033] When the ultrasonic tool rod vibrates, the position of the light spot reflected by the end face vibrates accordingly. At this time, the displacement sensor converts the position of the light spot into an electrical signal output, and then derives the vibration waveform through supporting facilities.

[0034] The test module 18 is mounted on the movable portion of the second horizontal slide 13 via a support plate 15 .

[0035] A locking block 10 is installed on the guide rail 3. A locking knob 11 is provided on the locking block 10 connected to the slider 4 or the positioning block 5. When the locking knob 11 is in a locked state, the locking block 10 is tightly matched with the guide rail 3. When the locking knob 11 is in an unlocked state, the locking block 10 is slidably matched with the guide rail 3.

[0036] When the locking knob is in an unlocked state, the inner wall of the adjusting slot is away from the guide rail. At this time, the position of the slider on the guide rail can be adjusted.

[0037] The locking block 10 is provided with a slide groove 121 that matches the guide rail 3. The locking block 10 is provided with an adjustment groove 122 located above the guide rail 3, and the lower end of the adjustment groove 122 is connected to the slide groove 121. The screw portion 111 of the locking knob 11 passes through the adjustment groove 122 and is threadedly connected to the locking block 10.

[0038] After the adjustment is completed, the screw rod cooperates with the thread of the adjustment groove, and the locking knob is rotated while driving the inner wall of the adjustment groove gradually closer until the locking block holds the guide rail tightly, thereby changing the distance between the ultrasonic tool rod and the test unit, ensuring the accuracy of the test and avoiding displacement of the slider during vibration.

[0039] At least three support legs 14 are installed on the lower surface of the base plate 1 and are spaced apart from each other.

[0040] The above two grooves 7 are both arc-shaped grooves:.

[0041] The working principle of the utility model is as follows:

[0042] First, one end of the ultrasonic knife rod is rigidly connected to the transducer, and then the transducer is placed in the clamping area surrounded by the positioning block and the clamping block to clamp the transducer;

[0043] When the locking knob is in an unlocked state, the inner wall of the adjusting groove is away from the guide rail. At this time, the position of the slider on the guide rail can be adjusted. After the adjustment is completed, the screw rod cooperates with the thread of the adjusting groove, and the locking knob is rotated while driving the inner wall of the adjusting groove to gradually approach until the locking block hugs the guide rail. At this time, when the locking knob is in a locked state, the inner wall of the adjusting groove hugs the guide rail, thereby changing the distance between the ultrasonic knife rod and the test unit, ensuring the accuracy of the test, and preventing the slider from being displaced during the vibration process;

[0044] When in use, the laser beam emitted by the laser generator irradiates the end face of the ultrasonic knife rod head, and the generated reflected light will be received by the receiving screen to form a light spot. When the ultrasonic knife rod is stationary, the test module is moved in the horizontal direction by turning the manual adjustment knobs on the first horizontal slide and the second horizontal slide respectively, until the light spot reflected by the ultrasonic knife rod can fall on the center of the receiving screen. At this time, the light spot position is set to zero, ensuring that the receiving screen can receive the reflected light spot in the subsequent test process, thereby improving the accuracy and efficiency of the test;

[0045] When the ultrasonic tool rod vibrates, the position of the light spot reflected by the end face vibrates accordingly. At this time, the displacement sensor converts the position of the light spot into an electrical signal output, and then derives the vibration waveform through supporting facilities.

[0046] When the above-mentioned ultrasonic knife rod test device is used, by rotating the manual adjustment knobs respectively installed on the first horizontal slide and the second horizontal slide, the test module can be adjusted in the horizontal direction after the transducer equipped with the ultrasonic knife rod is clamped and positioned, thereby returning the reflected light spot to zero, ensuring that the receiving screen can receive the reflected light spot in subsequent tests, thereby improving the accuracy and efficiency of the test, and the position of the clamped ultrasonic knife rod can be adjusted along its axial direction, so that the distance between each ultrasonic knife rod and the test unit can be adjusted to ensure the accuracy of the test, and the distance between the positioning block and the test unit can be adjusted according to the length of ultrasonic knife rods of different specifications, thereby improving versatility.

[0047] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
