Description

Technical Field

[0001] The invention relates to the field of acoustic measurement technology, and in particular to an impedance tube material sampling and cutting device and a use method thereof. Background Art

[0002] When using an impedance tube to test the sound absorption and insulation performance of a material, it is necessary to take samples from the material according to the size of the impedance tube. Currently, the sampling knife is usually installed on a bench drill to cut the material. However, in the process of rotating and cutting the material, the material may be driven to rotate due to the high-speed rotation of the tool. Therefore, the material needs to be fixed during cutting. However, for some soft materials, it is not convenient to use common clamps to fix them, and it is inconvenient to use a bench drill to cut such materials. At the same time, due to the limited stroke of the bench drill, cutting materials of different thicknesses requires adjusting the height of the bench drill's rotating drive assembly, which makes the cutting steps more cumbersome. Finally, when cutting the material, due to the obstruction of the line of sight, it is difficult to judge whether the tool has completely penetrated the material. Insufficient cutting depth will cause sampling failure, and excessive cutting depth may damage the tool. Summary of the invention

[0003] The purpose of the present invention is to provide an impedance tube material sampling and cutting device and a method of use to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] The present invention provides an impedance tube material sampling and cutting device, comprising:

[0007] The rotary cutting assembly comprises a rotary driving mechanism and the first lifting mechanism driving the rotary driving mechanism to move up and down, wherein the rotary driving mechanism is provided with a rotary driving end facing downward, and the rotary driving end is used to install a rotary cutting tool to drive the rotary cutting tool to rotate;

[0008] The tooling assembly includes a tooling table located below the rotating drive end, a second lifting mechanism for driving the tooling table to move up and down, and a pressure seat adjustable up and down between the tooling table and the rotating drive end, wherein the pressure seat is provided with a cutting hollow portion opposite to the rotating drive end and for the rotating cutting tool to pass through.

[0009] The impedance tube material sampling and cutting device of the present invention has the following beneficial effects:

[0010] When in use, the height position of the pressure seat between the workbench and the rotary driving end is adjusted in advance according to the thickness of the material to be sampled and cut. If the thickness of the material is large, the pressure seat is adjusted upward, and then the material to be sampled and cut is placed on the top side of the workbench, and the workbench is driven to move upward by the second lifting mechanism, and the material is clamped by the mutual approach of the workbench and the pressure seat, and then the rotary driving mechanism is driven downward by the first lifting mechanism to drive the rotary cutting tool to move downward and pass through the cutting hollow part. Under the drive of the rotary driving mechanism and the first lifting mechanism, the rotary cutting tool performs rotary cutting and sampling on the material. The present invention drives the workbench to move in the up and down directions by the second lifting mechanism and the up and down adjustable setting of the pressure seat, on the one hand, to match with the pressure seat to achieve clamping of the material, and on the other hand, for materials of different thicknesses, the up and down position of the pressure seat can be adjusted to adjust the initial distance between the top of the material and the rotary cutting tool, so that the rotary cutting tool penetrates the material during rotary cutting when the up and down stroke of the rotary cutting tool is fixed.

[0011] As a further improvement of the above technical solution, the workbench is provided with an upwardly disposed receiving groove, and the receiving groove matches the shape and size of the pressure seat so that the pressure seat extends into the receiving groove along the up and down directions.

[0012] When in use, the material is placed in the accommodating groove, which plays a role in limiting the placement of the material, and the pressure seat can extend into the accommodating groove from top to bottom to press the material in the accommodating groove. This has a better clamping effect on the material, and the clamping force in the up and down directions is used to clamp and fix the material. The material is limited by the inner wall of the accommodating groove to prevent the material from rotating with the rotating cutting tool during rotary cutting.

[0013] As a further improvement of the above technical solution, the workbench includes a base plate and four side panels distributed in a rectangular shape on the top surface of the base plate. The four side panels are divided into a detachable side panel and three fixed side panels. The two ends of the detachable side panel are respectively magnetically connected to two adjacent fixed sides.

[0014] The receiving groove in the present solution is composed of a bottom plate and four side plates. In some embodiments, when placing materials, the workbench can be lowered until the distance between the workbench and the press seat is greater than the thickness of the material, and the material can be placed from between the workbench and the press seat into the receiving groove. However, if the thickness of the material is large, the lowering stroke of the workbench may not be sufficient. In the present solution, the detachable side panels are removed to form an inlet on the side of the workbench, the material is placed into the receiving groove from the inlet, and then the detachable side panels are sealed. The detachable side panels of the present solution are fixed by magnetic attraction, which is convenient for disassembly and assembly.

[0015] As a further improvement of the above technical solution, the second lifting mechanism includes two plate seats arranged with an upper and lower interval, and a telescopic lifting device connected between the two plate seats, the telescopic lifting device includes two lifting frame bodies and a telescopic driving structure, the two lifting frame bodies are cross-arranged and tilted up and down, the middle parts of the two lifting frame bodies are hinged to each other, one end of the lifting frame body is hinged to one of the plate seats, and the other end of the lifting frame body is connected to the other plate seat in a transverse sliding manner and is defined as a transverse movement end, the telescopic driving structure is used to drive one of the transverse movement ends to move transversely, and the workbench is installed on the plate seat located on the upper side.

[0016] This solution uses a telescopic drive structure to drive the transverse movement end of one of the lifting frames to move horizontally, so as to drive the two lifting frames to rotate and telescope relative to each other, so as to drive the two plate seats to move closer to and away from each other in the up and down directions, thereby realizing the lifting and lowering of the workbench. This solution converts the transverse linear drive of the telescopic drive structure into the rotation of the lifting frame, and then converts the rotation of the lifting frame into the lifting and lowering of the workbench.

[0017] As a further improvement of the above technical solution, the telescopic driving structure includes a screw rod rotatably fixedly mounted on one of the plate seats, and the screw rod is threadedly connected to one of the transverse ends.

[0018] In this solution, a rotating screw is used to drive the lateral movement of the lateral moving end on one of the lifting frames, and the rotating screw is threadedly connected and cooperated with the lateral moving end to achieve a self-locking function.

[0019] As a further improvement of the above technical solution, the impedance tube material sampling and cutting device also includes a frame, the frame includes a base, a column vertically connected to the base, the pressure seat is connected to a fixing clamp, the pressure seat is adjusted up and down on the column through the fixing clamp, and the rotary cutting assembly is installed on the column;

[0020] The plate seat at the lower side is slidably mounted on the base along a first direction, and the tooling table is slidably mounted on the plate seat at the upper side along a second direction. The first direction and the second direction are perpendicular to each other on a horizontal plane.

[0021] In this solution, the rotary cutting assembly and the pressure seat support are erected by means of columns, and the workbench and the second lifting mechanism are installed on the base. During installation and debugging, the position of the plate seat located on the lower side is adjusted along the first direction, and the position of the workbench is adjusted along the second direction to achieve the position adjustment of the workbench on the horizontal plane, so that the workbench is located directly below the rotary cutting tool.

[0022] As a further improvement of the above technical solution, the cut hollow portion is a stepped through hole with a large opening facing downward, the stepped through hole magnetically attracts a ring-shaped clamping plate, the middle of the clamping plate is provided with a cutting hole, and the outer edge of the clamping plate is provided with a positioning step that fits in the stepped through hole.

[0023] During sampling, in order to make the material sample cut by the rotary cutting tool more complete, that is to say, to improve the integrity of the material cut, this solution sets an annular clamping plate at the rotary cutting point to clamp the material. The size of the rotary cutting tool matches the cutting hole, so that the rotary cutting tool can more stably perform rotary cutting of the material. In addition, it is necessary to replace rotary cutting tools of different sizes according to the size of the impedance tube, and then it is also necessary to replace clamping plates with cutting holes of different sizes, so as to meet different cutting requirements. Moreover, the clamping plate of this solution is fixed to the step through hole by magnetic attraction, and the clamping plate is matched with the step through hole by positioning the step, so as to facilitate disassembly and replacement.

[0024] As a further improvement of the above technical solution, the impedance tube material sampling and cutting device also includes a cut-through sensing component, which includes a power supply, a prompt element and conductive silicone. The rotary cutting tool is a conductive component, and the conductive silicone is arranged on the top side of the workbench. The conductive silicone, power supply, prompt element and rotary cutting tool are connected in series in sequence.

[0025] When cutting the material, it is difficult to judge whether the rotary cutting tool has completely penetrated the material due to the obstructed line of sight. Insufficient cutting depth will cause sampling failure, and excessive cutting depth may damage the rotary cutting tool. Therefore, this solution also designs a cut-through sensing component. When the rotary cutting tool does not penetrate the material, the circuit between the rotary cutting tool and the conductive silicone is considered to be open, and the circuit is not conductive at this time; when the rotary cutting tool penetrates the material and touches the conductive silicone, the circuit is conductive, and the prompt element will generate a corresponding prompt. It can be understood that the setting of the cut-through sensing component can remind the user when the rotary cutting tool just cuts through the material.

[0026] As a further improvement of the above technical solution, the prompt element includes an indicator light and a speaker connected in parallel.

[0027] When the rotary cutting tool penetrates the material and touches the conductive silicone, the circuit is connected, the speaker sounds and the indicator light comes on.

[0028] The present invention also provides a method for using the impedance tube material sampling and cutting device, the method comprising:

[0029] Placing the material to be sampled and cut on the conductive silicone rubber of the tooling table;

[0030] Adjusting the upper and lower positions of the press seat according to the thickness of the material;

[0031] The tooling table is driven to move upward by the second lifting mechanism so that the material is clamped between the tooling table and the press seat;

[0032] The first lifting mechanism drives the rotary drive mechanism to move downward, so as to drive the rotary cutting tool driven by the rotary drive mechanism to perform rotary cutting on the material;

[0033] When the rotary cutting tool contacts the conductive silicone, the prompt element sends out a prompt to monitor that the rotary cutting tool penetrates the material and the rotary cutting is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Reference Figure 1 to Figure 7 The impedance tube material sampling and cutting device of the present invention is implemented as follows:

[0058] like Figure 1 As shown, the impedance tube material sampling and cutting device of this embodiment includes a rotary cutting assembly 100 and a tooling assembly 200 .

[0059] like Figure 1 and Figure 2 As shown, the rotary cutting assembly 100 includes a rotary driving mechanism 110 and a first lifting mechanism 120, wherein the rotary driving mechanism 110 is provided with a rotary driving end 111, the axial direction of the rotary driving end 111 is vertically arranged, and the rotary driving end 111 is arranged downward, and the rotary driving end 111 is used to install a rotary cutting tool 130, and drive the rotary cutting tool 130 to rotate around a vertical axis to achieve a rotary cutting action. Specifically, the rotary driving mechanism 110 is built with a rotary motor, and the rotary cutting tool 130 is driven to rotate by the rotary motor, and a quick-release structure is used between the rotary driving end 111 and the rotary cutting tool 130 to achieve rapid replacement and assembly.

[0060] The first lifting mechanism 120 is used to drive the rotary drive mechanism 110 to move up and down, so as to drive the rotary cutting tool 130 to move up and down, so as to realize the feed and retract actions of rotary cutting. The first lifting mechanism 120 and the rotary drive mechanism 110 generally adopt a conventional bench drill structure, which will not be described in detail here. However, it should be noted that the stroke of the first lifting mechanism 120 to drive the rotary drive mechanism 110 to move up and down is fixed and the stroke is relatively short.

[0061] like Figure 1 , 2 3, the tooling assembly 200 includes a tooling table 210, a second lifting mechanism 220 and a pressure seat 230, wherein the tooling table 210 is arranged directly below the rotating drive end 111, the tooling table 210 is used to place the material 300 to be sampled and cut, and the pressure seat 230 is arranged between the tooling table 210 and the rotating drive end 111, and the pressure seat 230 is adjustable up and down relative to the tooling table 210 and the rotating drive end 111. It can be understood that, in a natural state, the height of the pressure seat 230 can be adjusted separately, and the pressure seat 230 is fixed between the tooling table 210 and the rotating drive end 111. In addition, the pressure seat 230 is provided with a cutting hollow portion that passes through from top to bottom, the position of the cutting hollow portion is opposite to the rotating drive end 111, and the rotating cutting tool 130 can pass through the cutting hollow portion.

[0062] The second lifting mechanism 220 is used to drive the tooling table 210 to move up and down. When in use, the height position of the pressure seat 230 between the tooling table 210 and the rotary drive end 111 is adjusted in advance according to the thickness of the material 300 to be sampled and cut. If the thickness of the material 300 is large, the pressure seat 230 is adjusted upward, and then the material 300 to be sampled and cut is placed on the top side of the tooling table 210, and the tooling table 210 is driven to move upward by the second lifting mechanism 220, and the material 300 is clamped by the mutual approach of the tooling table 210 and the pressure seat 230, and then the rotary drive mechanism 110 is driven to move downward by the first lifting mechanism 120 to drive the rotary cutting tool 130 to move downward, and Through the cutting hollow part, driven by the rotary drive mechanism 110 and the first lifting mechanism 120, the rotary cutting tool 130 performs rotary cutting and sampling on the material 300. The present invention drives the workbench 210 to move in the up and down directions and the up and down adjustable setting of the pressure seat 230 through the second lifting mechanism 220, on the one hand, to match with the pressure seat 230 to achieve clamping of the material 300, and on the other hand, for materials 300 of different thicknesses, the up and down positions of the pressure seat 230 can be adjusted to adjust the initial distance between the top of the material 300 and the rotary cutting tool 130. When the up and down stroke of the rotary cutting tool 130 is fixed, the rotary cutting tool 130 penetrates the material 300 during rotary cutting.

[0063] Furthermore, the top side of the workbench 210 of the present embodiment is provided with an upwardly disposed receiving groove 211, and the receiving groove 211 matches the shape and size of the pressure seat 230 so that the pressure seat 230 can extend into the receiving groove 211 in the up and down directions. When in use, the material 300 is placed in the receiving groove 211, which plays a role in limiting the placement of the material 300, and the pressure seat 230 can extend into the receiving groove 211 from top to bottom to press the material 300 in the receiving groove 211, so that the clamping effect on the material 300 is better, and the clamping force in the up and down directions is used to clamp and fix the material 300, and the material 300 is limited by the inner wall of the receiving groove 211 to prevent the material 300 from rotating with the rotating cutting tool 130 during rotary cutting.

[0064] like Figure 3 and Figure 4 As shown, the receiving groove 211 of this embodiment is a rectangular groove structure, and the workbench 210 includes a bottom plate 212 and four side plates distributed in a rectangular shape on the top surface of the bottom plate 212. The receiving groove 211 is composed of the bottom plate 212 and the four side plates.

[0065] In some embodiments, when placing the material 300 , the tooling table 210 can be lowered until the distance between the tooling table 210 and the press seat 230 is greater than the thickness of the material 300 , so that the material 300 can be placed from between the tooling table 210 and the press seat 230 into the receiving groove 211 .

[0066] If the thickness of the material 300 is relatively large, the descending stroke of the workbench 210 may not be sufficient. Therefore, in this embodiment, the four side panels are divided into a removable side panel 216 and three fixed side panels 213. The three fixed side panels 213 are fixedly mounted on the bottom plate 212, while the removable side panel 216 is removable. When discharging the material, the removable side panel 216 is removed, and an inlet 214 is formed on the side of the workbench 210. The material 300 is placed from the inlet 214 into the containing groove 211, and then the removable side panel 216 is sealed.

[0067] The detachable side panel 216 of this embodiment is disposed at the front side, so that an entrance 214 is formed on the front side of the workbench 210 for easy operation.

[0068] The two ends of the removable side panel 216 of the present embodiment are respectively connected to the two adjacent fixed side magnetic connections. Specifically, the inner side surfaces of the two ends of the removable side panel 216 of the present embodiment are provided with holes for placing magnets, and the magnetic attraction of the removable side panel 216 is achieved by magnets. In order to improve the firmness of the installation, reinforcement holes are also provided at both ends of the removable side panel 216. The reinforcement holes are provided with handles with M6 threads. The handles with M6 threads can be used to lock the removable side panel 216 to ensure safety.

[0069] Regarding the specific structure of the second lifting mechanism 220, Figures 1 to 4 As shown, the second lifting mechanism 220 of the present embodiment includes two plate seats and a telescopic lifting device. The two plate seats are arranged at an interval up and down, and the two plate seats are divided into an upper plate seat 221 and a lower plate seat 222, and the telescopic lifting device is connected between the upper plate seat 221 and the lower plate seat 222. The telescopic lifting device includes two lifting frames 223 and a telescopic driving structure. The two lifting frames 223 are arranged crosswise and tilted up and down. The middle parts of the two lifting frames 223 are hinged to each other through a hinge shaft 224 extending forward and backward. The lifting frames 223 are arranged to be tilted up and down. The two ends of the lifting frames 223 in the up and down directions are divided into a hinge end 2231 and a transverse movement end 2232, and the hinge end 2231 is hinged to one of the plate seats, and the transverse movement end 2232 is connected to the other plate seat for horizontal sliding left and right. The telescopic driving structure is used to drive one of the transverse movement ends 2232 to move horizontally left and right, and the workbench 210 is installed on the top side of the upper plate seat 221.

[0070] In this embodiment, the telescopic drive structure is used to drive the transverse end 2232 on one of the lifting frames 223 to move horizontally, so as to drive the two lifting frames 223 to rotate and telescope relative to each other, so as to drive the upper plate seat 221 and the lower plate seat 222 to move closer to and away from each other in the up and down directions, thereby realizing the lifting and lowering of the workbench 210. In this embodiment, the transverse linear drive of the telescopic drive structure is converted into the rotation of the two lifting frames 223, and then the rotation of the two lifting frames 223 is converted into the lifting and lowering of the workbench 210.

[0071] The telescopic driving structure includes a screw 225 rotatably fixedly mounted on the upper plate seat 221, and the screw 225 is threadedly connected to one of the transverse ends 2232. In some embodiments, the screw 225 can be installed on the lower plate seat 222. The embodiment of the present invention drives the transverse end 2232 on one of the lifting frame bodies 223 to move laterally by rotating the screw 225, and the rotating screw 225 is threadedly connected to the transverse end 2232 to achieve a self-locking function.

[0072] For ease of operation, a rotating wheel 2251 is provided at the outer end of the screw rod 225 .

[0073] In some other embodiments, the telescopic drive structure may adopt other linear drive structures.

[0074] like Figure 1 As shown, for the installation of the pressure seat 230, the present embodiment is further provided with a frame 400, wherein the frame 400 includes a base 410 and a column 420, the column 420 is vertically connected to the base 410, a fixing clamp 231 is connected to the rear side of the pressure seat 230, and the pressure seat 230 is installed on the column 420 in an adjustable manner up and down by the fixing clamp 231. When the up and down position of the pressure seat 230 needs to be adjusted, the fixing clamp 231 can be loosened.

[0075] In addition, the rotary cutting assembly 100 is also installed on the column 420, and the lower plate seat 222 is slidably installed on the base 410 along the first direction, and the workbench 210 is slidably installed on the upper plate seat 221 along the second direction. The first direction and the second direction are arranged perpendicular to each other on the horizontal plane. The first direction of this embodiment is the front-to-back direction, and the second direction is the left-to-right direction.

[0076] like Figure 1 and Figure 3 As shown, the base 410 of this embodiment is provided with a plurality of front and rear slide grooves 411 arranged along the front and rear directions, and the lower plate seat 222 is adjustably connected to the front and rear slide grooves 411 through a bolt and nut structure, and the bottom of the workbench 210 is provided with a plurality of left and right slide grooves 215 extending along the left and right directions, and the upper plate seat 221 is adjustably connected to the left and right slide grooves 215 through a bolt and nut structure.

[0077] In this embodiment, the rotary cutting assembly 100 and the pressure seat 230 are supported and erected by the column 420, and the workbench 210 and the second lifting mechanism 220 are installed on the base 410. During installation and debugging, the position of the plate seat located on the lower side is adjusted along the first direction, and the position of the workbench 210 is adjusted along the second direction to achieve the position adjustment of the workbench 210 on the horizontal plane, so that the workbench 210 is located directly below the rotary cutting tool 130.

[0078] like Figure 5 and Figure 6 As shown, the cut hollow portion of the present embodiment is a stepped through hole 232, the large mouth of the stepped through hole 232 is arranged downward, the stepped through hole 232 is magnetically attracted with a ring-shaped clamping plate 240, the middle part of the clamping plate 240 is provided with a cutting hole 241 which passes through from top to bottom, and the outer edge of the clamping plate 240 is provided with a positioning step 242 which is positioned and sleeved with the stepped through hole 232.

[0079] During sampling, in order to make the sample of material 300 cut out by the rotary cutting tool 130 more complete, that is to say, to improve the integrity of the cut of the material 300, the present solution sets an annular clamping plate 240 at the rotary cutting position to clamp the material 300. The size of the rotary cutting tool 130 matches the cutting hole 241, so that the rotary cutting tool 130 can perform rotary cutting of the material 300 more stably. In addition, it is necessary to replace rotary cutting tools 130 of different sizes according to the size of the impedance tube, and then it is also necessary to replace clamping plates 240 with cutting holes 241 of different sizes, so as to meet different cutting requirements. In addition, the clamping plate 240 of the present solution is fixed to the step through hole 232 by magnetic attraction, and the clamping plate 240 is matched with the step through hole 232 by positioning the step 242, so as to facilitate disassembly and replacement.

[0080] like Figure 1 The impedance tube material sampling and cutting device shown is used for cutting small diameter materials 300, such as Fig. 9 The impedance tube material sampling and cutting device shown is for cutting large diameter material 300 .

[0081] Furthermore, when cutting the material 300 , it is difficult to determine whether the rotary cutting tool 130 completely penetrates the material 300 due to the obstructed line of sight. Insufficient cutting depth may cause sampling failure, while excessive cutting depth may damage the rotary cutting tool 130 .

[0082] like Figure 7 As shown, the impedance tube material sampling and cutting device of this embodiment also includes a cutting-through sensing component, which includes a power supply 500, a prompt element and a conductive silicone 600. The rotating cutting tool 130 is a conductive component. The conductive silicone 600 is arranged on the top side of the workbench 210. An insulating material 300 is arranged between the conductive silicone 600 and the workbench 210. The conductive silicone 600, the power supply 500, the prompt element and the rotating cutting tool 130 are connected in series in sequence.

[0083] When the rotary cutting tool 130 does not penetrate the material 300, the circuit between the rotary cutting tool 130 and the conductive silicone 600 is considered to be open, and the circuit is not conductive; when the rotary cutting tool 130 penetrates the material 300 and touches the conductive silicone 600, the circuit is conductive, and the prompt element will generate a corresponding prompt. It can be understood that the setting of the cut-through sensing component can enable the rotary cutting tool 130 to remind the user when it just cuts through the material 300.

[0084] The prompt element includes an indicator light 700 and a speaker 800 connected in parallel. When the rotary cutting tool 130 penetrates the material 300 and touches the conductive silicone 600, the circuit is turned on, the speaker 800 makes a sound and the indicator light 700 lights up.

[0085] like Figure 8 As shown, the present invention also provides a method for using the impedance tube material sampling and cutting device, the method comprising:

[0086] Step S100: placing the material 300 to be sampled and cut on the conductive silicone 600 of the tooling table 210;

[0087] Step S200: adjusting the upper and lower positions of the pressing seat 230 according to the thickness of the material 300;

[0088] Step S300: The second lifting mechanism 220 drives the tooling table 210 to move upward, so that the material 300 is clamped between the tooling table 210 and the press seat 230;

[0089] Step S400: The first lifting mechanism 120 drives the rotary drive mechanism 110 to move downward, so as to drive the rotary cutting tool 130 driven by the rotary drive mechanism 110 to perform rotary cutting on the material 300;

[0090] Step S500: When the rotary cutting tool 130 contacts the conductive silicone 600, the prompt element sends a prompt to monitor that the rotary cutting tool 130 penetrates the material 300 and the rotary cutting is completed.

[0091] In step S100, the removable side panel 216 is removed, and an inlet 214 is formed on the side of the workbench 210. The material 300 is placed into the receiving groove 211 from the inlet 214, and then the removable side panel 216 is sealed. The rotating cutting tool 130 of the corresponding size is replaced according to the size of the impedance tube, and the clamping plate 240 of the cutting hole 241 of the corresponding size also needs to be replaced.

[0092] In step S200 , the fixing clip 231 is loosened, the pressing seat 230 is adjusted to a set position, and then the fixing clip 231 is fixed.

[0093] In step S300, the screw rod 225 is rotated to drive the transverse end 2232 on one of the lifting frames 223 to move laterally, so as to drive the two lifting frames 223 to rotate and retract relative to each other, so as to drive the two plate seats to move closer to and away from each other in the vertical direction, thereby realizing the lifting and lowering of the tooling table 210.

[0094] In step S500, when the rotary cutting tool 130 penetrates the material 300 and touches the conductive silicone 600, the circuit is turned on, the speaker 800 makes a sound and the indicator light 700 lights up, and the rotary driving mechanism 110 stops moving downward.

[0095] The present invention is used to achieve clamping when sampling and cutting the material 300 and is convenient to adjust for materials 300 of different sizes and thicknesses. At the same time, the device is equipped with a reminder function, which can remind the user in time when the rotary cutting tool 130 just penetrates the material 300 to avoid sampling failure or damage to the rotary cutting tool 130.

[0096] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
