[0025] When in use, one end of the ultrasonic knife rod is rigidly connected to the transducer, the transducer is placed in the groove on the positioning block, and then the front end of the driving rod is pressed downward and the front end of the rotating rod is driven to move downward. The clamping block approaches the positioning block until the transducer is clamped, and the other end of the ultrasonic knife rod is located above the supporting wheel, which can not only realize the clamping and positioning of one end of the ultrasonic knife rod installed on the transducer, but also provide stable support for the other end of the ultrasonic knife rod.

[0026] The receiving groove 122 is a V-shaped groove.

[0027] The bottom surface of the accommodating groove 122 is an arc-shaped surface matching the outer surface of the ultrasonic knife rod 4 .

[0028] An elastic gasket 121 is attached to the inner wall of the receiving groove 122 .

[0029] The elastic gasket 121 is a rubber gasket;

[0030] It can form a flexible support for the knife bar to prevent the ultrasonic knife bar from getting hot or even damaged due to high-frequency friction and impact during vibration.

[0031] The base 91 is mounted on the positioning block 5 via an L-shaped connecting block 13 . The vertical portion 131 of the L-shaped connecting block 13 is connected to the positioning block 5 , and the base 91 is mounted on the horizontal portion 132 of the L-shaped connecting block 13 .

Since the specifications of the test piece are different, the height of the strip mounting hole can be adjusted according to the different diameters of the transducer, and the distance between the two grooves can be changed, so that the diameter of the clamping area is suitable for tool rods with different diameters.

[0034] Embodiment 2: A stable tool bar test support mechanism comprises: a bottom plate 1 and a vertical plate 2 installed on the upper surface of the bottom plate 1, a positioning block 5 is installed on the upper surface of one end of the vertical plate 2, a clamping block 6 is arranged above the positioning block 5, a groove 7 is provided on the lower surface of the rotatable clamping block 6 and the upper surface of the positioning block 5, so that a clamping area 8 is surrounded by two relatively arranged grooves 7, a strip plate 11 is provided on the outer side of the other end of the vertical plate 2, a supporting wheel 12 is installed on the upper end of the vertically extending strip plate 11 and on the side thereof facing the vertical plate 2, a receiving groove 122 extending along the circumferential direction thereof is provided on the outer circumferential surface of the upper part of the supporting wheel 12 located above the vertical plate 2, the other end of the ultrasonic tool bar 4 connected to the transducer 3 at one end is embedded in the receiving groove 122 and contacts and cooperates with the inner wall of the receiving groove 122, and the transducer 3 is embedded in the clamping area 8;

[0035] A base 91 is provided on one side of the positioning block 5, and the lower part of one end of a rotating rod 92 is rotatably connected to the base 91, and the other end of the rotating rod 92 extends to the top of the positioning block 5 and is connected to the clamping block 6. The upper part of the rotating rod 92 connected to the base 91 is rotatably connected to a driving rod 94, and the other end of the driving rod 94 connected to the rotating rod 92 at one end extends in a direction away from the clamping block 6. A connecting rod 93 is provided on the rotating rod 92 on the side opposite to the positioning block 5, and the upper end of the connecting rod 93 rotatably connected to the base 91 at the lower end is rotatably connected to the driving rod 94;

[0036] In the initial state, the front end of the driving rod tilts upward and drives the front end of the rotating rod upward. At this time, the clamping block is away from the positioning block;

[0037] During the test, the other end of the ultrasonic knife rod was placed in the accommodating groove. The rolling support wheel alleviated the friction generated by the friction between the two when the ultrasonic knife rod moved longitudinally. The contact between the ultrasonic knife rod and the elastic gasket can alleviate the situation where the ultrasonic knife rod becomes hot or even damaged due to high-frequency friction and impact during vibration.

[0038] The above-mentioned receiving groove 122 is a V-shaped groove, and the V-shaped receiving groove can limit the lateral vibration of the ultrasonic knife rod, thereby further improving the accuracy of the test.

[0039] An elastic gasket 121 is attached to the inner wall of the receiving groove 122 .

[0040] The elastic gasket 121 is a silicone gasket.

[0041] The base 91 is mounted on the positioning block 5 via an L-shaped connecting block 13 . The vertical portion 131 of the L-shaped connecting block 13 is connected to the positioning block 5 , and the base 91 is mounted on the horizontal portion 132 of the L-shaped connecting block 13 .

[0042] The lower end of the strip plate 11 is mounted on the side surface of the vertical plate 2 .

[0043] The lower end of the strip plate 11 is provided with a plurality of strip through holes 111 extending in the vertical direction, and the vertical plate 2 is provided with a plurality of second circular mounting holes 14 cooperating with the strip through holes 111;

[0044] At this time, by adjusting the position of the strip through hole in the vertical direction, the height of the support wheel is adjusted until the ultrasonic knife rod can contact the support wheel and is located in the test position. This can adapt to ultrasonic knife rods of different heights and avoid the ultrasonic knife rod being suspended or tilted, causing breakage during vibration.

[0045] At least three support legs 10 are installed on the lower surface of the base plate 1 and are spaced apart from each other.

[0046] The two grooves 7 are both arc-shaped grooves.

[0047] The working principle of the utility model is as follows:

[0048] In the initial state, the front end of the driving rod tilts upward and drives the front end of the rotating rod upward. At this time, the clamping block is away from the positioning block;

[0049] When in use, one end of the ultrasonic knife rod is rigidly connected to the transducer, and the transducer is placed in the groove on the positioning block. Then the front end of the driving rod is pressed downward and the front end of the rotating rod is driven to move downward, and the clamping block approaches the positioning block until the transducer is clamped, and the other end of the ultrasonic knife rod is located above the supporting wheel, which can realize the clamping and positioning of one end of the ultrasonic knife rod installed on the transducer, and can also provide stable support for the other end of the ultrasonic knife rod;

[0050] At this time, by adjusting the position of the strip through hole in the vertical direction, the height of the support wheel is adjusted until the ultrasonic knife rod can contact the support wheel and is located in the test position, which can adapt to ultrasonic knife rods of different heights and avoid the ultrasonic knife rod being suspended or tilted, resulting in breakage during vibration.

[0051] During linear adjustment, the locking knob is in the unlocked state. At this time, by adjusting the position of the slider on the slide rail, after the adjustment is completed, the screw rod cooperates with the thread of the adjustment groove, and the inner wall of the adjustment groove is gradually approached while rotating the locking knob until the locking block holds the guide rail tightly, thereby changing the distance between the test piece and the test unit, ensuring the accuracy of the test, and preventing the slider from shifting during vibration.

[0052] During this process, the other end of the ultrasonic knife rod is placed in the accommodating groove. The rolling support wheel alleviates the friction generated by the friction between the two when the ultrasonic knife rod moves longitudinally. The contact between the ultrasonic knife rod and the elastic gasket can alleviate the situation where the ultrasonic knife rod becomes hot or even damaged due to high-frequency friction and impact during vibration. The V-shaped accommodating groove can limit the lateral vibration of the ultrasonic knife rod, further improving the accuracy of the test.

[0053] When the above-mentioned stable knife rod test support mechanism is adopted, it can not only realize the clamping and positioning of one end of the ultrasonic knife rod installed on the transducer, but also stably support and limit the other end of the ultrasonic knife rod, thereby ensuring the stability of the ultrasonic knife rod during the test to improve the test accuracy; further, through the rotatable setting of the clamping block, it improves the convenience of clamping and disassembly of the test piece while protecting the test piece, which is beneficial to improve the test efficiency.

[0054] 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.
