[0051] See also Figure 1-Figure 4The embodiment of the present invention provides an ultrasonic toolholder load performance test platform 200 (hereinafter referred to as the test platform 200), which is used to measure the amplitude curve at the end surface of the tool 601 when the tool 601 loaded on the ultrasonic toolholder 600 is subjected to different loads. The test platform 200 includes: a loading platform 100, a toolholder fixing mechanism 300, a laser displacement sensor fixing mechanism 400 and a pressure sensor fixing mechanism 500. The toolholder fixing mechanism 300, the laser displacement sensor fixing mechanism 400 and the pressure sensor fixing mechanism 500 are all installed on the loading platform 100.

[0052] The tool holder fixing mechanism 300 is used to fix the ultrasonic tool holder 600, and the ultrasonic tool holder 600 is installed with a tool 601. Specifically, the ultrasonic tool holder 600 includes a primary side 602 and a secondary side 603, and the tool 601 is installed on the secondary side 603. The primary side 602 is provided with a primary coil, and the secondary side 603 is provided with a secondary coil. The test platform 200 may also include a power supply, which can wirelessly transmit electric energy through the primary coil and the secondary coil, and then load an ultrasonic signal of a certain voltage and frequency on the tool 601 to make the tool 601 vibrate. Moreover, the distance between the primary coil and the secondary coil can be adjusted to achieve different radio transmission effects according to performance or test requirements. In this embodiment, when the test platform 200 tests the tool 601, the tool 601 does not rotate. The ultrasonic tool holder load performance test platform 200 can be applied to ultrasonic machining systems.

[0053] Please combine Figure 1 The tool handle fixing mechanism 300 includes a first driving mechanism 101 , a second driving mechanism 102 , a third driving mechanism 103 , a first tool handle support pair 112 and a second tool handle support pair 113 .

[0054] The first driving mechanism 101 is installed on the loading platform 100 , the second driving mechanism 102 is installed on the first driving mechanism 101 , and the third driving mechanism 103 is installed on the second driving mechanism 102 .

[0055] The first tool handle bracket pair 112 is mounted on the second driving mechanism 102, and the second driving mechanism 102 is used to drive the first tool handle bracket pair 112 to clamp the primary edge 602 of the ultrasonic tool handle 600. The second tool handle bracket pair 113 is mounted on the third driving mechanism 103, and the third driving mechanism 103 is used to drive the second tool handle bracket pair 113 to clamp the secondary edge 603 of the ultrasonic tool handle 600. In this way, the fixation and position adjustment of the tool 601 can be achieved.

[0056] Specifically, the first driving mechanism 101 can be fixedly mounted on the loading platform 100, and the position of the ultrasonic knife handle 600 in the Y-axis direction can be adjusted by adjusting the first driving mechanism 101 (see Figure 1The coordinate system shown in the figure), the Y-axis direction may include the positive direction of the Y-axis and the negative direction of the Y-axis. The first driving mechanism 101 may include a screw driving mechanism or a linear motor driving mechanism, the second driving mechanism 102 may include a screw driving mechanism or a linear motor driving mechanism, and the third driving mechanism 103 may include a screw driving mechanism or a linear motor driving mechanism. In the embodiment shown in the accompanying drawings, the first driving mechanism 101, the second driving mechanism 102 and the third driving mechanism 103 all adopt a screw driving mechanism, and the structure of the screw driving mechanism is simple and the cost is low. Among them, the first driving mechanism 101 includes two sliders, the second driving mechanism 102 is fixed on one of the sliders of the first driving mechanism 101, and the third driving mechanism 103 is fixed on the other slider of the first driving mechanism 101. The first tool handle bracket pair 112 and the second tool handle bracket pair 113 are respectively fixed on the sliders of the second driving mechanism 102 and the third driving mechanism 103.

[0057] It can be understood that in other embodiments, the first, second and third driving mechanisms may also adopt other driving mechanisms that can achieve linear motion, which is not specifically limited here.

[0058] The first tool handle bracket pair 112 is formed with a first clamping notch 115, which is in a rhombus or circular shape, and the second tool handle bracket pair 113 is formed with a second clamping notch 116, which is in a rhombus or circular shape. In this way, the tool handle can be clamped to prevent the tool handle from shaking unexpectedly during the test and affecting the test results.

[0059] Each pair of tool handle brackets includes two opposite brackets, and opposite sides of the two brackets are respectively formed with a V-shaped or semicircular notch, and the two notches of the two brackets together form a diamond-shaped or circular clamping notch.

[0060] exist Figure 1 In the illustrated embodiment, the first clamping notch 115 and the second clamping notch 116 are both rhombus-shaped, and the rhombus-shaped clamping notch has good versatility and can be applied to various types of ultrasonic knife handles 600. In other embodiments, the first clamping notch and the second clamping notch can also be made into a circle according to the size of the ultrasonic knife handle 600, and can be applied to a specific type of knife handle.

[0061] The laser displacement sensor fixing mechanism 400 includes a laser displacement sensor 111 for detecting the amplitude curve at the end face of the tool 601. Specifically, during the test, the power supply loads an ultrasonic signal of a set voltage and frequency to the tool 601 to make the tool 601 vibrate. The laser displacement sensor 111 can emit a laser to the end face of the tool 601 and receive the reflected laser from the end face of the tool 601. The amplitude curve at the end face of the tool 601 can be measured by the displacement change of the reflected laser. Those skilled in the art can refer to the relevant technology for the specific principle, which will not be elaborated in detail here.

[0062] The laser displacement sensor fixing mechanism 400 includes a fourth driving mechanism 104, a fifth driving mechanism 105 and a sixth driving mechanism 106. The fourth driving mechanism 104 is mounted on the loading platform 100, the fifth driving mechanism 105 is mounted on the fourth driving mechanism 104, the sixth driving mechanism 106 is mounted on the fifth driving mechanism 105, and the laser displacement sensor 111 is mounted on the sixth driving mechanism 106. The fourth driving mechanism 104, the fifth driving mechanism 105 and the sixth driving mechanism 106 are respectively used to adjust the position of the laser displacement sensor 111 in the Z-axis, Y-axis and X-axis directions. In this way, the position adjustment and fixing of the laser displacement sensor 111 can be achieved.

[0063] Specifically, the fourth driving mechanism 104 can be fixedly mounted on the loading platform 100. The fourth driving mechanism 104 may include a screw driving mechanism or a linear motor driving mechanism. The fifth driving mechanism 105 may include a screw driving mechanism or a linear motor driving mechanism. The sixth driving mechanism 106 may include a screw driving mechanism or a linear motor driving mechanism. In the embodiment shown in the accompanying drawings, the fourth driving mechanism 104, the fifth driving mechanism 105 and the sixth driving mechanism 106 all adopt a screw driving mechanism, and the structure of the screw driving mechanism is simple and low in cost. Among them, the fifth driving mechanism 105 is fixed on the slider of the fourth driving mechanism 104, and the sixth driving mechanism 106 is fixed on the slider of the fifth driving mechanism 105. The laser displacement sensor 111 is fixed on the slider of the sixth driving mechanism 106.

[0064] It can be understood that in other embodiments, the fourth, fifth and sixth driving mechanisms may also adopt other driving mechanisms that can realize linear motion, which is not specifically limited here.

[0065] The pressure sensor fixing mechanism 500 includes a pressure sensor 110 and a force loading frame 114. The force loading frame 114 is connected to the pressure sensor 110. The laser displacement sensor 111 is placed in the force loading frame 114 and is located between the pressure sensor 110 and the tool 601. The force loading frame 114 is provided with a through groove 117. The groove 117 is used for laser transmission (including the laser emitted by the laser displacement sensor 111 and the laser reflected by the tool 601). The pressure sensor fixing mechanism 500 is used to apply a load to the tool 601 through the pressure sensor 110 and the force loading frame 114.

[0066] Specifically, the force loading frame 114 is a frame. Figure 1 In the illustrated embodiment, the force loading frame 114 is a square frame, and the laser displacement sensor 111 is placed in the square frame. The laser displacement sensor 111 is placed in the force loading frame 114, and the laser displacement sensor 111 is spaced from the periphery of the force loading frame 114. The laser displacement sensor 111 and the force loading frame 114 are separate structures, and the vibration of the tool 601 will not be transmitted to the laser displacement sensor 111 to affect the test result.

[0067] The force loading frame 114 includes a first side 118 and a second side 119 relative to each other, and a third side 120 and a fourth side 121 relative to each other. The third side 120 and the fourth side 121 are connected to the first side 118 and the second side 119 respectively. The first side 118 is fixedly connected to the pressure sensor 110. The second side 119 is provided with a groove 117. The groove width of the groove 117 is smaller than the diameter of the tool 601, and the length of the groove 117 meets the requirements of the laser transmission path.

[0068] Specifically, the first side 118 can be fixedly connected to the pressure sensor 110 by screws. The groove 117 provided on the second side 119 is a vertical groove. In one example, the groove width of the groove 117 is 1 mm, and the diameter of the tool 601 is 4 mm. It can be understood that the specific numerical values ​​in the above examples are only for the convenience of explaining the present invention, and cannot be understood as limiting the present invention. The numerical values ​​appearing in other parts of the present invention specification should also be understood as herein.

[0069] The length of the slot 117 meets the requirements of the laser transmission path. It can be understood that the length of the slot 117 should allow the laser emitted by the laser displacement sensor 111 to the tool 601 to pass through the slot 117, and the laser reflected by the tool 601 to pass through the slot 117. In this way, the laser displacement sensor 111 can measure the vibration curve at the end face of the tool 601.

[0070] The surface of the second side 119 opposite to the tool 601 is provided with buffer parts 122 located on both sides of the groove 117, and the buffer parts 122 are used to abut the tool 601. In this way, it can be prevented that the force loading frame 114 and the tool 601 are damaged due to hard contact between the force loading frame 114 and the tool 601 during the test process.

[0071] In one example, the buffer component 122 may be rubber. In other embodiments, the buffer component 122 may also be other components, such as a material having a lower hardness than the force loading frame 114 and the cutter 601 and having a certain elasticity.

[0072] The pressure sensor fixing mechanism 500 includes a seventh driving mechanism 107, an eighth driving mechanism 108 and a ninth driving mechanism 109. The seventh driving mechanism 107 is mounted on the loading platform 100, the eighth driving mechanism 108 is mounted on the seventh driving mechanism 107, and the ninth driving mechanism 109 is mounted on the eighth driving mechanism 108. One end of the pressure sensor 110 is connected to the ninth driving mechanism 109, and the other end of the pressure sensor 110 is connected to the force loading frame 114. The seventh driving mechanism 107, the eighth driving mechanism 108 and the ninth driving mechanism 109 are respectively used to adjust the positions of the pressure sensor 110 and the force loading frame 114 in the Z-axis, Y-axis and X-axis directions. In this way, the position adjustment and fixing of the pressure sensor 110 and the force loading frame 114 can be achieved.

[0073] Specifically, the seventh drive mechanism 107 can be fixedly mounted on the loading platform 100. The seventh drive mechanism 107 includes a screw drive mechanism or a linear motor drive mechanism, the eighth drive mechanism 108 includes a screw drive mechanism or a linear motor drive mechanism, and the ninth drive mechanism 109 includes a screw drive mechanism or a linear motor drive mechanism. In the embodiment shown in the accompanying drawings, the seventh drive mechanism 107, the eighth drive mechanism 108 and the ninth drive mechanism 109 all adopt a screw drive mechanism, and the structure of the screw drive mechanism is simple and low in cost. Among them, the eighth drive mechanism 108 is fixed on the slider of the seventh drive mechanism 107, and the ninth drive mechanism 109 is fixed on the slider of the eighth drive mechanism 108. One end of the pressure sensor 110 is fixed on the slider of the ninth drive mechanism 109, and the other end is fixedly connected to the force loading frame 114.

[0074] Furthermore, please combine Figure 5 The test platform 200 includes a controller 123 and a control handle 124. The control handle 124 is electrically connected to the controller 123. The controller 123 is used to control the operation of the test platform 200 according to the control signal of the control handle 124. In this way, the required control of the test platform 200 can be achieved.

[0075] Specifically, the controller 123 may include a PLC controller or other controllers, and the control handle 124 may be provided with physical or virtual buttons, which can realize the control of the operating state of the test platform 200, for example, control the movement of each drive mechanism, the switch of each electrical component, including but not limited to realizing the position adjustment and fixation of the tool 601, the laser displacement sensor 111, and the pressure sensor 110, and loading a certain voltage and frequency ultrasonic signal to the tool 601, and ending the test, etc. In an embodiment of the present invention, each drive mechanism adopts a screw drive mechanism to further reduce costs. In the test platform 200 of this embodiment, the 9 groups of screw drive mechanisms are manual, and the hand wheel is manually rotated to adjust the position of the slider in the screw drive mechanism. In other embodiments, the screw drive mechanism can also be improved to automatic adjustment, which can be achieved by assembling a motor in the screw drive mechanism.

[0076] Please combine Figure 6 The embodiment of the present invention provides a method for testing the load performance of an ultrasonic tool holder, which is used in the test platform 200 of the above embodiment to measure the amplitude curve at the end face of the tool 601 when the tool 601 loaded on the ultrasonic tool holder 600 is subjected to different loads.

[0077] Ultrasonic toolholder load performance test methods include:

[0078] Step 01, fix the ultrasonic knife handle 600 using the knife handle fixing mechanism 300;

[0079] Step 02, adjusting the pressure sensor fixing mechanism 500 so that the groove of the force loading frame abuts against the end surface of the tool 601;

[0080] Step 03, adjusting the laser displacement sensor fixing mechanism 400 so that the laser displacement sensor 111 can detect the amplitude curve at the end surface of the tool 601, and the laser emitted by the laser displacement sensor 111 and the laser reflected by the tool 601 can both pass through the slot 117 of the force loading frame 114;

[0081] Step 04, adjust the pressure sensor fixing mechanism 500, apply load to the tool 601 by the force loading frame 114, and record the end face amplitude curve of the tool 601 detected by the laser displacement sensor 111 under different load conditions.

[0082] The above-mentioned ultrasonic tool holder load performance test method can use a laser displacement sensor to measure the amplitude curve at the end face of the tool while applying a load on the tool of the ultrasonic tool holder through a pressure sensor, thereby realizing the performance test of the ultrasonic tool holder.

[0083] Specifically, in the above steps, each driving mechanism can be controlled so that the groove of the force loading frame is against the end surface of the tool 601, so that the laser displacement sensor 111 can detect the amplitude curve at the end surface of the tool 601, and the force loading frame 114 applies a load to the tool 601.

[0084] Specifically, in step 01, the ultrasonic knife handle 600 is clamped by the second driving mechanism 102 and the third driving mechanism 103, thereby fixing the ultrasonic knife handle 600 and the knife 601. The position of the ultrasonic knife handle 600 in the Y-axis direction can also be adjusted by the first driving mechanism 101.

[0085] In step 02 , at least one of the fourth, fifth and sixth driving mechanisms 106 may be used to make the groove 117 of the force loading frame abut against the end surface of the tool 601 .

[0086] In step 03, at least one of the seventh, eighth and ninth driving mechanisms 109 can be used to enable the laser displacement sensor 111 to detect the amplitude curve at the end surface of the tool 601, and the laser emitted by the laser displacement sensor 111 and the laser reflected by the tool 601 can both pass through the slot 117 of the force loading frame 114.

[0087] In step 04, by setting different loads (such as pressure), the corresponding amplitude curve is measured. During the test, a certain voltage and frequency ultrasonic signal is applied to the tool 601 to make the tool 601 vibrate. In one example, the first group of amplitude curves is measured by no load, that is, a load of 0 Newton is applied, and then a load of 5 Newton is applied to measure the second group of amplitude curves, and then a load of 10 Newton is applied to measure the third group of amplitude curves, and so on. In this way, the load range in which the tool 601 works effectively can be obtained, and the performance test of the tool 601 is achieved.

[0088] In summary, the advantages of the present invention include but are not limited to the following:

[0089] 1. While a load is applied to the tool 601 of the ultrasonic tool holder 600, the laser displacement sensor 111 can be used to measure the amplitude curve at the end surface of the tool 601;

[0090] 2. The laser displacement sensor 111 and the force loading frame 114 are separate structures, and the vibration of the tool 601 will not be transmitted to the laser displacement sensor 111;
