Specific embodiments

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] As Figures 1 to 5 shown, the structure and function of a temperature sensor will be described in detail below;

[0033] A temperature sensor, an outer side of the temperature sensor 35 is fixedly connected with a mounting sleeve 31, a bottom of the mounting sleeve 31 is fixedly connected with an arc insert 32, the mounting sleeve 31 is mounted on the top shell 12, the top shell 12 is fixedly connected to the bottom shell 11, a positioning block 21 is slidably connected between the top shell 12 and the bottom shell 11, a sliding column 22 is fixedly connected to the positioning block 21, the sliding column 22 is slidably connected between the top shell 12 and the bottom shell 11, a compression spring is fixedly connected between the positioning block 21 and the top shell 12 and the bottom shell 11, an arc slot 23 is provided on the positioning block 21, and the arc insert 32 can be inserted into the arc slot 23;

[0034] During use, when the temperature sensor 35 is vibrated, the mounting sleeve 31 is used for shock absorption. The mounting sleeve 31 is preferably made of an elastic material, and the arc-shaped insert block 32 is preferably made of an elastic material, such as rubber, etc. The up-and-down movement of the temperature sensor 35 is realized through the positioning block 21, that is, the temperature sensor 35 can offset a part of the upward movement and can automatically reset after extending, thereby offsetting the vibrations generated in the up-and-down reverse directions;

[0035] A positioning protrusion 33 is provided on the arc-shaped insert block 32, and a positioning hole 24 is provided on the positioning block 21. The positioning protrusion 33 can be snapped into the positioning hole 24;

[0036] The positioning protrusion 33 is preferably made of an elastic material, such as rubber, etc.;

[0037] Two marking grooves 13 are provided on the top shell 12, and a marking strip 34 is fixedly connected to the mounting sleeve 31;

[0038] During installation, the mounting sleeve 31 is fixedly connected to the outside of the temperature sensor 35 in advance, and then the mounting sleeve 31 is inserted into the top shell 12. During initial installation, the marking strip 34 on the mounting sleeve 31 points to the marking groove 13 inclined at 45°, so that the plurality of arc-shaped insert blocks 32 at the bottom of the mounting sleeve 31 can be inserted between the plurality of positioning blocks 21, and then the mounting sleeve 31 is rotated so that the plurality of arc-shaped insert blocks 32 are respectively turned into the plurality of arc-shaped slots 23. At this time, the marking strip 34 points to the vertically arranged marking groove 13, indicating that the connection is completed. In this way, when a person installs and uses it, they can accurately know that the arc-shaped insert block 32 has been installed in place, and the connection between the mounting sleeve 31 and the plurality of positioning blocks 21 is completed; this connection method can ensure a stable connection between the mounting sleeve 31 and the plurality of positioning blocks 21, and due to the indication marks of the marking groove 13 and the marking strip 34, it can ensure that the mounting sleeve 31 is installed in place, preventing the positioning protrusion 33 from not being snapped into the positioning hole 24 due to the improper installation of the mounting sleeve 31. When vibrated, the mounting sleeve 31 is prone to rotation, causing the mounting sleeve 31 to disengage from the plurality of positioning blocks 21, and further causing the temperature sensor 35 to fall;

[0039] Further, in order to ensure that the arc insert block 32 does not rotate when the installation sleeve 31 is vibrated after the arc insert block 32 enters the arc slot 23, causing the arc insert block 32 to separate from the arc slot 23, a positioning protrusion 33 is provided. The positioning protrusion 33 can be snapped into the positioning hole 24. That is, when the arc insert block 32 and the arc slot 23 are installed, since the arc insert block 32 and the positioning protrusion 33 are made of elastic materials, the arc insert block 32 and the positioning protrusion 33 are deformed, enabling the positioning protrusion 33 to smoothly enter the positioning hole 24. After the positioning protrusion 33 enters the positioning hole 24, the positioning protrusion 33 resumes its deformation, and then the positioning protrusion 33 is snapped into the positioning hole 24, ensuring that the temperature sensor 35 will not cause the arc insert block 32 to separate from the arc slot 23 due to vibration. In this way, the installation is completed;

[0040] As Figures 6 to 11 shown, in order to facilitate the implementation of a temperature sensor manufacturing process, a temperature sensor manufacturing device is designed to facilitate the processing of the positioning block 21, which is the core part of the temperature sensor. The structure and function of the temperature sensor manufacturing device will be described in detail below;

[0041] A temperature sensor manufacturing device includes a base 41. A support ring 51 is fixedly connected to the base 41. A rotating ring 52 is rotatably connected to the support ring 51. A plurality of clamping mechanisms are fixedly connected to the rotating ring 52. A sliding bracket 42 is fixedly connected to the base 41. A cutting mechanism is slidably connected to the sliding bracket 42;

[0042] A lead screw 43 is rotatably connected to the sliding bracket 42. A power mechanism I for driving the lead screw 43 to rotate is fixedly connected to the sliding bracket 42. A power mechanism II for driving the rotating ring 52 to rotate is fixedly connected to the support ring 51;

[0043] Each clamping mechanism includes two telescopic mechanisms I 53. A clamping sleeve 54 is fixedly connected to the telescopic end of each telescopic mechanism I 53;

[0044] The cutting mechanism includes a telescopic mechanism II 61. The telescopic mechanism II 61 is slidably connected to the sliding bracket 42. The telescopic mechanism II 61 is threadedly connected to the lead screw 43. A rotating bracket 62 is rotatably connected to the telescopic end of the telescopic mechanism II 61. A power mechanism III for driving the rotating bracket 62 to rotate is fixedly connected to the telescopic mechanism II 61. A rotating seat 63 is fixedly connected to the rotating bracket 62. A plurality of telescopic mechanisms III 64 are fixedly connected to the rotating seat 63. A cutting bracket 65 is fixedly connected to the telescopic end of each telescopic mechanism III 64;

[0045] A plurality of sliding seats 71 are slidably connected to the cutting support 65. A telescopic mechanism IV 72 is fixedly connected to each sliding seat 71. A cutting tool 73 is rotatably connected to the telescopic end of each telescopic mechanism IV 72. A power mechanism IV for driving the cutting tool 73 to rotate is fixedly connected to the telescopic end of each telescopic mechanism IV 72. Two telescopic mechanisms V 74 are fixedly connected to the cutting support 65. A compression spring is fixedly connected between the sliding seats 71. The telescopic end of the telescopic mechanism V 74 abuts against the sliding seat 71;

[0046] The multiple cutting tools 73 on each cutting support 65 are arranged in a staggered manner, and the cutting areas of the multiple cutting tools 73 can overlap;

[0047] During use, as Figure 6 shown, a plurality of to-be-processed positioning blocks 81 to be processed are respectively placed on the multiple clamping mechanisms. The telescopic mechanism I 53 is started. The telescopic mechanism I 53 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 53 drives the clamping sleeve 54 to move, so that the two clamping sleeves 54 approach each other, and the clamping sleeve 54 is sleeved on the sliding column 22 of the to-be-processed positioning block 81. The two clamping sleeves 54 squeeze and clamp the side edges of the to-be-processed positioning block 81, and the clamping of the to-be-processed positioning block 81 is completed;

[0048] As Figure 6 shown, the position of the clamping mechanism located on the lower side is set as the processing station here, and the remaining positions are the clamping stations of the to-be-processed positioning blocks 81, or the stations for disassembling the positioning block 21 after processing;

[0049] The power mechanism II is started. The power mechanism II is preferably a servo motor. The power mechanism II can be fixedly connected to the support ring 51. A toothed ring can be fixedly connected to the support ring 51. A gear can be fixedly connected to the output shaft of the power mechanism II. The toothed ring and the gear are meshed and driven. Then, when the output shaft of the power mechanism II starts to rotate, the output shaft of the power mechanism II drives the gear to rotate, the gear drives the toothed ring to rotate, and the toothed ring drives the support ring 51 to rotate;

[0050] The output shaft of the power mechanism II can drive the rotating ring 52 to rotate. When the rotating ring 52 rotates, it drives the multiple clamping mechanisms to move, so that the clamping mechanisms move to the processing station, that is, the to-be-processed positioning block 81 is moved to the processing position, or the processed positioning block 21 is moved out of the processing position;

[0051] Further, start the power mechanism I. The power mechanism I is preferably a servo motor. The power mechanism I can be fixedly connected to the sliding bracket 42. The output shaft of the power mechanism I can drive the lead screw 43 to rotate. The output shaft of the power mechanism I drives the lead screw 43 to rotate. When the lead screw 43 rotates, it drives the telescopic mechanism II 61 to move through the thread. The telescopic mechanism II 61 drives the rotating bracket 62, the rotating seat 63, the telescopic mechanism III 64, the cutting bracket 65, the sliding seat 71, the telescopic mechanism IV 72, the cutting tool 73, and the telescopic mechanism V 74 to move, thereby adjusting the lateral positions of the multiple cutting tools 73 and adjusting the relative positions of the cutting tool 73 and the to-be-processed positioning block 81.

[0052] When the to-be-processed positioning block 81 moves to the processing position, start the power mechanism III. The power mechanism III is preferably a servo motor. The output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the rotating bracket 62 to rotate. The rotating bracket 62 drives the multiple cutting tools 73 to rotate. Start the telescopic mechanism II 61. The telescopic mechanism II 61 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 61 drives the rotating bracket 62 to move, thereby adjusting the height of the rotating bracket 62. The rotating bracket 62 drives the multiple cutting tools 73 to move, adjusting the relative distance between the multiple cutting tools 73 and the to-be-processed positioning block 81, and completing the cutting of the to-be-processed positioning block 81, so that the end shape of the to-be-processed positioning block 81 is an arc surface. The shape of the arc surface can fit on the outer side of the mounting sleeve 31, ensuring the contact between the mounting sleeve 31 and the positioning block 21. The stably connected mounting sleeve 31 and positioning block 21 can improve the damping effect.

[0053] Further, start the power mechanism IV. The power mechanism IV is preferably a servo motor. The power mechanism IV can be fixedly connected to the telescopic end of the telescopic mechanism IV 72. The output shaft of the power mechanism IV drives the cutting tool 73 to rotate.

[0054] Further, when it is necessary to adjust the cutting radius of the multiple cutting tools 73 according to the diameter of the mounting sleeve 31, start the telescopic mechanism III 64. The telescopic mechanism III 64 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 64 drives the cutting bracket 65 to move. The cutting bracket 65 drives the multiple cutting tools 73 to move, thereby adjusting the rotation radius of the multiple cutting tools 73 during rotation, and further adjusting the size of the arc diameter formed when cutting the to-be-processed positioning block 81.

[0055] Further, when the arc slot 23 needs to be cut and processed, the telescopic mechanism Ⅳ 72 is started. The telescopic mechanism Ⅳ 72 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism Ⅳ 72 drives the cutting tool 73 to move, so that one of the multiple cutting tools 73 extends out, changing the cutting radius of the cutting tool 73, and then enabling the cutting tool 73 to cut the to-be-processed positioning block 81 to form the arc slot 23;

[0056] Further, when the width of the arc slot 23 formed by processing needs to be adjusted, multiple telescopic mechanisms Ⅳ 72 are started to make multiple cutting tools 73 extend out. As Figure 10 shown, there is an overlapping cutting area among the multiple cutting tools 73. Then, by adjusting the relative distance between the cutting tools 73, the processing width can be adjusted. Further, the telescopic mechanism Ⅴ 74 is started. The telescopic mechanism Ⅴ 74 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism Ⅴ 74 drives the sliding seat 71 to move, so that the multiple sliding seats 71 are pressed against each other. And compression springs are arranged between the multiple sliding seats 71 to be able to position the sliding seat 71. Since during rotary cutting, the cutting tool 73 receives the reaction force of the to-be-processed positioning block 81, and this reaction force is perpendicular to the direction of the driving force when the sliding seat 71 slides. With the positioning of the compression spring, it is ensured that the sliding seat 71 does not generate lateral movement when the cutting tool 73 is cutting; then the relative distance between the cutting tools 73 is adjusted, the cutting area of the extended cutting tool 73 is adjusted, and further the width of the arc slot 23 formed by cutting is adjusted;

[0057] Further, when cutting the positioning block 21, the multiple cutting tools 73 first perform arc cutting on the end of the positioning block 21. When cutting the arc slot 23, the telescopic mechanism Ⅳ 72 at the specified position is started to make the telescopic mechanism Ⅳ 72 drive the specified cutting tool 73 to extend out, adjusting the cutting radius of the cutting tool 73 to achieve the cutting of the arc slot 23. At the same time, when the width of the arc slot 23 to be cut is relatively large, the telescopic mechanism Ⅴ 74 is started. First, the distance between the multiple cutting tools 73 for cutting the arc slot 23 is made smaller, and a smaller slot is cut first. Then, the telescopic mechanism Ⅴ 74 is gradually started to make the multiple cutting tools 73 move away from each other, and the distance between the multiple cutting tools 73 is made larger, realizing the processing from small to large in width. Similarly, when cutting the depth of the arc slot 23, according to the processing requirements of the depth of the arc slot 23, the telescopic mechanism Ⅳ 72 can also be started to make the multiple cutting tools 73 gradually extend out to complete the cutting and processing of the arc slot 23;

[0058] Here, to clearly distinguish between the cutting of the end arc shape of the positioning block 21 and the cutting of the arc slot 23, when multiple cutting tools 73 are within the same cutting radius during rotation, it is the cutting of the end arc shape of the positioning block 21. When some of the multiple cutting tools 73 extend to produce a larger cutting radius, it is the cutting of the arc slot 23. Here, by controlling the length of the extended end of the telescopic mechanism Ⅳ72, the cutting radius of the cutting tool 73 is controlled and adjusted, and the distance between multiple cutting tools 73 and the overlapping cutting part are adjusted by the telescopic mechanism Ⅴ74;

[0059] Further, by starting the power mechanism Ⅲ, the output shaft of the power mechanism Ⅲ drives the rotating seat 63 to rotate, thereby driving multiple cutting tools 73 to move. During the rotation of the multiple cutting tools 73, a virtual cutting circle is generated based on the cutting radius of the multiple cutting tools 73. Start multiple telescopic mechanisms Ⅳ72 to move the outer ends of the multiple cutting tools 73 to the virtual cutting circle to complete the cutting of the positioning block 81 to be processed. Since the multiple cutting tools 73 are arranged in a staggered manner, that is, the multiple cutting tools 73 on each cutting bracket 65 contact the end of the positioning block 81 to be processed successively, the cutting area is reduced, the cutting effect is ensured. At the same time, during the start of the telescopic mechanism Ⅴ74, the relative distance between the multiple cutting tools 73 can be adjusted. Thus, after the first cutting tool 73 cuts the positioning block 81 to be processed, when the second cutting tool 73 cuts the positioning block 81 to be processed again, the cutting width of the second cutting tool 73 can be adjusted to meet different processing requirements;

[0060] Further, by starting the telescopic mechanism Ⅲ64, the positions of the multiple cutting tools 73 can be adjusted as a whole, thereby adjusting the cutting radius of the multiple cutting tools 73 and further adjusting the size of the arc diameter formed when cutting the positioning block 81 to be processed, so that the end of the positioning block 81 to be processed can fit mounting sleeves 31 with different diameters;

[0061] Embodiment 1: This embodiment is for facilitating chip removal and improving the tool life.

[0062] Set the first set of cutting tools 73 to have a small cutting width but a large cutting depth; the second set of cutting tools 73 has an increased cutting width relative to the first set of cutting tools 73, but the cutting depth is one-third of that of the first set of cutting tools 73; the third set of cutting tools 73 has an increased cutting width relative to the second set of cutting tools 73, but the cutting depth is two-thirds of that of the first set of cutting tools 73; the fourth set of cutting tools 73 has an increased cutting width relative to the third set of cutting tools 73, but the cutting depth increases to be the same as that of the first set of cutting tools 73; when the first set of cutting tools 73 cuts the to-be-machined positioning block 81, a groove with a small width but a large depth will be machined on the to-be-machined positioning block 81. Compared with the cutting method of directly machining a large width and a large depth at one time, the mutual force between the tool and the workpiece to be machined can be greatly reduced, thereby improving the tool life. Secondly, the second set of cutting tools 73 starts to cut the to-be-machined positioning block 81. The cutting width of the second set of cutting tools 73 increases, but the depth is small, which can reduce the mutual force between the tool and the workpiece to be machined, thereby improving the tool life. And the waste chips generated by cutting can be discharged from the groove cut by the first set of cutting tools 73. The principles of the third set of cutting tools 73 and the fourth set of cutting tools 73 are the same as those of the second set, gradually increasing the cutting width and the cutting depth, reducing the mutual force between the tool and the workpiece to be machined, thereby improving the tool life. The groove cut by the first set of cutting tools 73 is also convenient for chip removal.

[0063] Embodiment 2: In this embodiment, cooperative cutting is carried out to effectively suppress the vibration of the workpiece and improve the machining quality.

[0064] In each set of tools of the present invention, there are multiple cutting tools 73. When cutting the to-be-machined positioning block 81, the multiple cutting tools 73 in each set can be superimposed in the cutting width. Thus, by synchronously rotating the multiple cutting tools 73 in each set of tools, the cutting force distribution becomes more uniform, avoiding the forced vibration caused by single-point cutting, thereby effectively suppressing the vibration of the workpiece and improving the machining quality. In this embodiment, the method of gradually increasing the cutting depth of the second set of cutting tools 73, the third set of cutting tools 73, and the fourth set of cutting tools 73 can also be used to reduce the mutual force between each set of tools and the workpiece to be machined, thereby improving the tool life. Similarly, in the width direction, the above method can also be used to gradually increase the width of each set of tools for machining, so as to effectively suppress the vibration of the workpiece, improve the machining quality, and at the same time improve the tool life.

[0065] Embodiment 3: This embodiment is a further expansion of Embodiment 2, which can reduce the surface waviness of the machined surface.

[0066] In each set of tools of the present invention, there are multiple cutting tools 73. When cutting the to-be-machined positioning block 81, the multiple cutting tools 73 can be superimposed in the cutting width. By adjusting the superimposing ratio, the tool paths are superimposed to form a continuous cutting band, reducing the waviness of the machined surface.

[0067] Embodiment 4: This embodiment performs cooperative cutting, facilitating chip evacuation and enhancing the service life of the cutting tool 73.

[0068] In each set of tools of the present invention, there are multiple cutting tools 73. As Figure 9 shown, there are four cutting tools 73, but this is only an embodiment and does not limit that each set of cutting tools 73 in the present invention must be 4, and it can also be other quantities. The following takes the Figure 9 shown case as an example. Along the rotational cutting direction of the cutting tool 73, the first tool contacting the to-be-machined positioning block 81 is called the first cutting tool 73, and the subsequent contacting ones are respectively called the second cutting tool 73, the third cutting tool 73, and the fourth cutting tool 73. The first cutting tool 73, the second cutting tool 73, the third cutting tool 73, and the fourth cutting tool 73 also have a certain distance from front to back in the cutting rotational direction. That is to say, the first cutting tool 73 is the first to cut the to-be-machined positioning block 81, leaving a groove on the to-be-machined positioning block 81. Secondly, the second cutting tool 73 starts to cut the to-be-machined positioning block 81, and the generated waste chips will be discharged from the groove machined by the first cutting tool 73. Similarly, then the third cutting tool 73 starts to cut the to-be-machined positioning block 81, and the generated waste chips will be discharged from the grooves machined by the first cutting tool 73 and the second cutting tool 73. Finally, the fourth cutting tool 73 cuts the to-be-machined positioning block 81. Through this tool arrangement, chip evacuation is facilitated, and the cutting width of each tool is reduced, reducing the interaction force between each tool and the workpiece to be machined, thereby enhancing the tool life.

[0069] Embodiment 5: In this embodiment, multiple sets of cutting tools 73 pass by the to-be-machined positioning block 81 with a gap, reducing the temperature during the machining of the to-be-machined positioning block 81, reducing the temperature of the cutting tool 73, and improving the service life of the cutting tool 73 and the machining accuracy of the to-be-machined positioning block 81;

[0070] As Figure 9As shown, four cutting tools 73 on a cutting bracket 65 form a set of tools. When the driving rotating seat 63 rotates, the rotating seat 63 drives a plurality of cutting brackets 65 to move, so that multiple sets of cutting tools 73 sequentially pass through the to-be-processed positioning block 81 to cut the to-be-processed positioning block 81. Since there is a movement gap between multiple sets of tools, that is, after a set of cutting tools 73 finishes cutting, it takes a period of time for the next set of cutting tools 73 to pass. During this period, the to-be-processed positioning block 81 can dissipate heat, thereby ensuring that the to-be-processed positioning block 81 will not be deformed by heat, and further ensuring the processing accuracy of the to-be-processed positioning block 81;

[0071] Embodiment 6: This embodiment is a further expansion of Embodiment 5, which can reduce the damage of the cutting tool 73; by multiple sets of cutting tools 73 sequentially passing through the to-be-processed positioning block 81, each set of tools can undertake different cutting tasks, that is, start the telescopic mechanism V 74, and the telescopic end of the telescopic mechanism V 74 drives the cutting tool 73 to move, thereby adjusting the lateral position of each set of cutting tools 73. Thus, each set of cutting tools 73 undertakes different cutting tasks, that is, the first set of cutting tools 73 cuts one-fourth, that is, the second set of cutting tools 73 cuts the second one-fourth, and so on. Reducing the cutting tasks of each set of cutting tools 73 can reduce the damage of the cutting tool 73;

[0072] Embodiment 7: In this embodiment, the rotation directions of the cutting tools 73 are different, reducing the cutting ripples generated at the end of the to-be-processed positioning block 81; here, the cutting tasks of multiple sets of cutting tools 73 can be the same, that is, the cutting areas of each set of cutting tools 73 are the same, but the rotation direction of the first set of cutting tools 73 is clockwise, and the rotation direction of the second set of cutting tools 73 is counterclockwise. Thus, after the first set of cutting tools 73 finishes cutting, the second set of cutting tools 73 passes through the cutting position, that is, the multiple cutting tools 73 of the first set rotate clockwise, and the multiple cutting tools 73 of the second set rotate counterclockwise. After the multiple cutting tools 73 of the first set generate cutting marks, the multiple cutting tools 73 of the second set rotate in the reverse direction, thereby offsetting the cutting marks generated by the multiple cutting tools 73 of the first set;

[0073] A manufacturing process for a temperature sensor, the process comprising the following steps:

[0074] Step 1: Place the to-be-processed positioning block 81 on the clamping mechanism for clamping; place multiple to-be-processed positioning blocks 81 to be processed on multiple clamping mechanisms respectively, and start the telescopic mechanism I 53. The telescopic mechanism I 53 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 53 drives the clamping sleeve 54 to move, so that the two clamping sleeves 54 approach each other, and the clamping sleeve 54 is sleeved on the sliding column 22 of the to-be-processed positioning block 81. The two clamping sleeves 54 squeeze and clamp the side of the to-be-processed positioning block 81 to complete the clamping of the to-be-processed positioning block 81.

[0075] Step 2: Drive the rotating ring 52 to rotate so that the to-be-processed positioning block 81 moves to the processing position; the output shaft of the power mechanism II can drive the rotating ring 52 to rotate. When the rotating ring 52 rotates, it drives multiple clamping mechanisms to move, so that the clamping mechanism moves to the processing station, that is, the to-be-processed positioning block 81 is moved to the processing position, or the processed positioning block 21 is moved out of the processing position.

[0076] Step 3: The cutting mechanism moves to cut the to-be-processed positioning block 81 so that the to-be-processed positioning block 81 forms an arc end face and an arc slot 23; after the to-be-processed positioning block 81 moves to the processing position, start the power mechanism III. The power mechanism III is preferably a servo motor. The output shaft of the power mechanism III starts to rotate, and the output shaft of the power mechanism III drives the rotating bracket 62 to rotate. The rotating bracket 62 drives multiple cutting tools 73 to rotate. Start the telescopic mechanism II 61. The telescopic mechanism II 61 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 61 drives the rotating bracket 62 to move, thereby adjusting the height of the rotating bracket 62. The rotating bracket 62 drives multiple cutting tools 73 to move, and adjusts the relative distance between the multiple cutting tools 73 and the to-be-processed positioning block 81 to complete the cutting of the to-be-processed positioning block 81.
