Description

Technical Field

[0001] The invention belongs to the technical field of mechanical protection equipment, in particular to a tool presetter for a numerically controlled machine tool. Background Art

[0002] The tool presetter for CNC machine tools, also known as the tool setting instrument, is a measuring device that can pre-adjust and measure the tool tip diameter and clamping length, and can input tool data into the NC program of the machining center. With the popularization of NC machine tools equipped with multi-tool automatic tool changers, the market for high-precision and high-efficiency tool presetters is continuing to expand. The presetter is mainly used for pre-adjustment of products such as cutting tools, iron knives, and drill bits.

[0003] At present, when the tool presetter for CNC lathes is used, when the presetter gradually moves close to products such as cutting knives, iron knives, and drill bits, the protective rubber at the top of the lower slide rail will be in a more compact folded shape. When it is away from products such as cutting knives, iron knives, and drill bits, the protective rubber at the top of the lower slide rail will be in a normal folded shape. However, when the cutting knives, iron knives, and drill bits are being tested, iron filings adhered to their surfaces will fall into the folded area of ​​the protective rubber at the top of the slide rail. At this time, due to the limitation of the rubber material and the large number of folded and bent areas, the staff cannot handle it quickly, which will affect the next preset detection effect. At the same time, the detection area at the top of the presetter will be damaged during long-term use. The glass protective cover on the outer wall of the detection part will be covered with dust. If it is not cleaned in time, it will affect the reception of the signal and cause data deviation. Therefore, a tool presetter for CNC machine tools is proposed to provide good protection for the presetter. For the tool presetter mentioned in this application, please refer to the following website: https: / / www.bilibili.com / video / BV17s4y1U7A5 / ?vd_source=711269d7ba2f1f232796311826823116. The tool presetter in this website is a device removed from the CNC machine tool and is installed to match the CNC machine tool. It is only shown as an independent device in the display. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a tool presetter for CNC machine tools, which solves the disadvantages of the prior art that there are a lot of iron filings on the top surface of the protective rubber on the top of the slide rail of the tool presetter for CNC machine tools, and a lot of dust on the protective glass cover at the outer end of the detection part, thereby affecting the subsequent presetting detection effect.

[0005] To achieve the above object, the present invention provides the following technical solutions: A tool presetting instrument for a numerical control machine tool, comprising a tool presetting instrument body for a numerical control machine tool and a mounting bracket. The tool presetting instrument body for a numerical control machine tool is movably connected to the bottom of the mounting bracket. One side of the upper end of the mounting bracket is movably clamped with a fixing bracket. A protective wiping assembly is movably clamped inside the mounting bracket and the fixing bracket. One end of the middle of the mounting bracket close to the fixing bracket is connected by a bearing to a rotating assembly. The rotating assembly is in transmission connection with the protective wiping assembly. One end of the lower end of the mounting bracket close to the fixing bracket is fixedly connected to a protection unit. One side of the top of the protection unit close to the mounting bracket is fixedly connected to a connection assembly. The connection assembly is meshed with the rotating assembly. A blowing assembly located on one side of the connection assembly is fixedly installed on the top of the protection unit. Both sides of the blowing assembly are fixedly connected to a movable assembly. The lower end of the movable assembly is fixedly connected to the protection unit. Both ends of the connection assembly are sleeved with a transmission assembly. The transmission assembly is fixedly connected to a side wall of the protection unit close to the mounting bracket.

[0006] Preferably, a positioning assembly is fixedly installed on one side of the bottom end of the protection unit close to the mounting bracket. One end of the protection unit away from the mounting bracket is hinged to a limiting unit. The bottom end of the limiting unit is in contact connection with the tool presetting instrument body for a numerical control machine tool. When the tool presetting instrument body for a numerical control machine tool is in use, place the device on the top of the tool presetting instrument body for a numerical control machine tool, and rotate the positioning assembly to make it clamped on the surface of the limiting unit. Through the positioning connection between the limiting unit and the positioning assembly, the device can be well fixed on the top of the tool presetting instrument body for a numerical control machine tool.

[0007] Preferably, the protective wiping assembly includes a first wiping unit. The first wiping unit is connected by a bearing to the fixing bracket. A second wiping unit is movably clamped inside one end of the first wiping unit away from the fixing bracket. The second wiping unit is connected by a bearing to the upper end of the mounting bracket. The surface of the first wiping unit is in transmission connection with the rotating assembly. The rotating assembly includes a rotating shaft and a belt. The two ends of the rotating shaft are respectively connected by a bearing to the fixing bracket and the mounting bracket. The rotating shaft is in transmission connection with the protective wiping assembly through the belt. One end of the rotating shaft away from the belt is fixedly connected to a gear. The surface of the gear is meshed with the connection assembly.

[0008] Preferably, the first wiping unit includes a first wiping roller, which is connected to the fixed frame by bearings. A positioning groove is formed on the surface of the top end of the first wiping unit. The second wiping unit includes a second wiping roller, which is connected to the mounting frame by bearings. A first spring telescopic tube is fixedly connected to the bottom of the inner cavity at the top end of the second wiping roller. The top of the first spring telescopic tube is fixedly connected to a positioning block, and the upper end of the positioning block is movably connected to the inner wall of the positioning groove. Pulling the second wiping roller will drive the positioning block to move inside the positioning groove. Through the design of multiple positioning grooves, the effect of fixing the second wiping roller and the first wiping roller at different positions is realized. By adjusting the distance value between the first wiping unit and the second wiping unit, it is applicable to the distance values of different tool presetters for detecting preset positions.

[0009] Preferably, the connecting component includes a worm, which is connected to the top end of the protection unit by bearings. Transmission components are sleeved at both ends of the worm. Spring pieces are fixedly connected to both sides of the surface of the worm. A protective shell is fixedly installed on the outer surface of the spring pieces, and the spring pieces are fixedly connected to the protection unit through the protective shell. The worm will rotate through the transmission component. After the worm rotates, it will drive a gear to rotate through the middle position thereof, and then drive the entire rotating shaft to rotate. The protective wiping component is driven to move through the rotating shaft, thus facilitating the wiping effect of the subsequent protective wiping component.

[0010] Preferably, the protection unit includes a rectangular positioning frame, which is fixedly connected to the mounting frame. A protection plate is movably connected inside the rectangular positioning frame. A magnetic absorption arc block is movably connected inside the protection plate. A second spring telescopic tube is fixedly connected to the top of the magnetic absorption arc block, and the top of the second spring telescopic tube is fixedly connected to the inner wall of the protection plate. Both ends of the protection plate are fixedly connected to the movable component. The bottom surface of the magnetic absorption arc block is arc-shaped.

[0011] Preferably, the blowing assembly includes a placement bin, which is fixedly connected to the top of the protection unit. Both sides of the top end of the placement bin are movably sleeved with leather plug blocks. One end of the placement bin away from the mounting frame is fixedly connected to an air outlet pipe. One end of the air outlet pipe away from the placement bin is hinged with a baffle plate. One side wall of the baffle plate away from the air outlet pipe is fixedly connected to a first arc-shaped spring telescopic cylinder. One end of the first arc-shaped spring telescopic cylinder away from the baffle plate is fixedly connected to the air outlet pipe. The moving assembly includes a first connecting pipe, which is fixedly connected to the blowing assembly. The lower end of the first connecting pipe is fixedly connected to a second connecting pipe, which is fixedly connected to the protection unit. A piston block is movably sleeved inside the second connecting pipe. One end of the piston block away from the connecting assembly is fixedly installed with a C-shaped rod, which is fixedly connected to the protection unit. When the protection unit moves towards the mounting frame, the leather plug blocks will be repositioned on the top of the placement bin. The piston block will move backward inside the second connecting pipe. At this time, the air inside the second connecting pipe will enter the inside of the air outlet pipe. Due to the continuous pushing of the piston block, the gas located inside the air outlet pipe will impact the baffle plate, causing the baffle plate to fold, allowing the air inside the air outlet pipe to be discharged outward. Then, after cleaning the top of the slide rail at the lower end of the tool presetting instrument through multiple air outlet pipes, wind blowing is carried out.

[0012] Preferably, the limiting unit includes a limiting rubber arc plate, which is hinged to the protection unit. One end of the upper side wall of the limiting rubber arc plate away from the protection unit is fixedly connected to a second arc-shaped spring telescopic cylinder. One end of the second arc-shaped spring telescopic cylinder away from the limiting rubber arc plate is fixedly connected to the top of the protection unit. The positioning assembly includes a rubber gasket, which is fixedly connected to the protection unit. Both ends of the rubber gasket are fixedly installed with clamping columns. The outer surface of the clamping columns is movably sleeved with telescopic sleeves. One end of the telescopic sleeve away from the rubber gasket is movably clamped to the outer wall of the limiting unit. When the device is placed on the top of the slide rail at the lower end of the tool presetting instrument, the limiting rubber arc plate is folded so that its bottom end is connected to the outer wall of the tool presetting instrument. At this time, a stable positioning effect will be achieved for the device.

[0013] Preferably, the transmission assembly includes a round shaft, which is connected to the protection unit. A connecting rope is movably connected to the outer surface of the round shaft. The top of the connecting rope is fixedly connected to the connecting assembly. The bottom end of the connecting rope is fixedly connected to the protection unit. When the protection plate moves, it will pull the connecting rope to move together. At this time, the connecting rope will drive the worm to rotate, thus facilitating subsequent coordinated use.

[0014] Preferably, the outer shape of the air outlet pipe is in an "S" shape, and the opening at its bottom end faces downward. The bottom end of the air outlet pipe is located at the middle position of the protection unit. The "S" shape is more conducive to the filling and flow of air, and the limitation of its low position ensures that when the protection unit moves, it will not block the bottom end of the air outlet pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] Through the cooperation of structures such as magnetic attraction arc blocks and protection plates, the present invention realizes the cleaning of iron filings inside the folded area of the protective rubber at the top of the lower slide rail of the tool presetting instrument, ensuring that during the next movement, there will be no iron filings left to cause the protective rubber to rupture. Pull the protection plate to move the magnetic attraction arc blocks outward from the inside of the rectangular positioning frame. At this time, as the protection plate moves, the bottoms of the multiple magnetic attraction arc blocks will adsorb the iron filings at the folded part of the protective rubber, thereby achieving the effect of cleaning the iron filings and improving the protection effect of the tool presetting instrument when not in use;

[0017] Through the cooperation of structures such as the blowing component and the moving component, the present invention realizes the effect of secondary cleaning, ensuring the cleanliness of the inner wall of the folded area of the protective rubber. When the protection plate moves, its two ends will drive the piston blocks to pull outward inside the second connecting pipe, and air can enter the inside of the second connecting pipe. When the magnetic attraction arc blocks move towards one end of the mounting frame, the air inside the second connecting pipe will be squeezed by the piston blocks and enter the inside of the first connecting pipe, the placement bin, and the air outlet pipe, causing the air inside the air outlet pipe to impact the baffle, so that the baffle releases the closure of the air outlet pipe. At this time, the air will blow towards the top surface of the protective rubber through the air outlet pipe, thereby realizing the effect of secondary cleaning, ensuring the cleanliness of its folded area, and improving the protection effect of the tool presetting instrument when not in use;

[0018] Through the cooperation of structures such as the first wiping roller and the second wiping roller, the present invention realizes the wiping effect on the protective glass on the outer wall of the detection module of the presetting instrument, greatly improving the protection effect on the numerical control machine tool tool presetting instrument. The protection plate will drive the worm to rotate by pulling the connecting rope, and the worm will cause the gear to rotate. The rotation of the gear will drive the first wiping roller and the second wiping roller to rotate together through the belt. At this time, the first wiping roller and the positioning groove will wipe the protective glass on the outer wall of the detection module of the tool presetting instrument, thereby greatly improving the presetting effect during the next inspection of products such as reamers, iron cutters, and drills, and improving the protection effect of the tool presetting instrument when not in use.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 13 shown, the present invention provides a tool presetting instrument for a CNC machine tool, including a body 1 of the tool presetting instrument for a CNC machine tool and a mounting frame 2. The body 1 of the tool presetting instrument for a CNC machine tool is movably connected to the bottom of the mounting frame 2. One side of the upper end of the mounting frame 2 is movably clamped with a fixed frame 3. A protective wiping assembly 4 is movably clamped inside the mounting frame 2 and the fixed frame 3. One end of the middle part of the mounting frame 2 close to the fixed frame 3 is connected by a bearing with a rotating assembly 5. The rotating assembly 5 is in transmission connection with the protective wiping assembly 4. One end of the lower end of the mounting frame 2 close to the fixed frame 3 is fixedly connected with a protective unit 7. One side of the top of the protective unit 7 close to the mounting frame 2 is fixedly connected with a connecting assembly 6. The connecting assembly 6 is meshed with the rotating assembly 5. A blowing assembly 8 is fixedly installed on the top of the protective unit 7 on one side of the connecting assembly 6. Both sides of the blowing assembly 8 are fixedly connected with a moving assembly 9. The lower end of the moving assembly 9 is fixedly connected with the protective unit 7. Transmission assemblies 12 are sleeved at both ends of the connecting assembly 6. The transmission assemblies 12 are fixedly connected with one side wall of the protective unit 7 close to the mounting frame 2.

[0035] Adopting the above solution: Through the cooperation of the above structures, when the tool presetting instrument body 1 of the numerical control machine tool needs to be protected when not in use, pull the protection unit 7 so that its bottom end moves along the inside of the lower slide rail of the tool presetting instrument body 1 of the numerical control machine tool. The lower end of the protection unit 7 will adsorb and clean the iron filings at the folding part of the top of the slide rail. When the protection unit 7 moves, the protection unit 7 will drive the protection wiping component 4 to rotate through the connection component 6 and the rotating component 5. When the protection wiping component 4 rotates, both sides of it will wipe the outer glass surface of the upper detection module of the tool presetting instrument body 1 of the numerical control machine tool, so as to ensure the cleanliness of its surface. At the same time, when the protection unit 7 moves towards one side of the mounting frame 2, the protection unit 7 will blow air at the bent position of the top of the lower slide rail of the tool presetting instrument body 1 of the numerical control machine tool through the movable component 9, so as to achieve the effect of secondary cleaning, and further greatly improve its protection effect when not in use.

[0036] As Figure 1 and Figure 5 shown, a positioning component 11 is fixedly installed on one side of the bottom end of the protection unit 7 close to the mounting frame 2. One end of the protection unit 7 far from the mounting frame 2 is hinged with a limiting unit 10. The bottom end of the limiting unit 10 is in contact connection with the tool presetting instrument body 1 of the numerical control machine tool. The protection wiping component 4 includes a first wiping unit 401. The first wiping unit 401 is connected to the fixed frame 3 by a bearing. A second wiping unit 402 is movably clamped inside one end of the first wiping unit 401 far from the fixed frame 3. The second wiping unit 402 is connected to the upper end of the mounting frame 2 by a bearing. The surface of the first wiping unit 401 is in transmission connection with the rotating component 5. The rotating component 5 includes a rotating shaft 501 and a belt 502. The two ends of the rotating shaft 501 are respectively connected to the fixed frame 3 and the mounting frame 2 by bearings. The rotating shaft 501 and the protection wiping component 4 are in transmission connection through the belt 502. One end of the rotating shaft 501 far from the belt 502 is fixedly connected with a gear 503. The surface of the gear 503 is meshed with the connection component 6.

[0037] Adopting the above solution: Through the cooperation of structures such as the protective wiping component 4 and the rotating component 5, when the rotating shaft 501 rotates, it will drive the first wiping unit 401 to rotate through the belt 502. When the first wiping unit 401 rotates, it will drive the second wiping unit 402 to rotate together. At this time, the outer walls of the first wiping unit 401 and the second wiping unit 402 will rotate and wipe the outer wall of the glass protective cover of the detection area of the CNC machine tool tool presetting instrument body 1, so as to ensure the cleanliness of the glass outer cover surface when the CNC machine tool tool presetting instrument body 1 is used next time and improve the presetting effect; Through the cooperation of the limiting unit 10 and the positioning component 11, when the CNC machine tool tool presetting instrument body 1 is in use, place the device on the top of the CNC machine tool tool presetting instrument body 1, rotate the positioning component 11 to make it snap onto the surface of the limiting unit 10. Through the positioning connection of the limiting unit 10 and the positioning component 11, the device can be well fixed on the top of the CNC machine tool tool presetting instrument body 1.

[0038] As Figure 6 shown, the first wiping unit 401 includes a first wiping roller 4011, the first wiping roller 4011 is connected to the fixed frame 3 by bearings, a positioning groove 4012 is formed on the surface of the top end of the first wiping unit 401, the second wiping unit 402 includes a second wiping roller 4021, the second wiping roller 4021 is connected to the mounting frame 2 by bearings, a first spring telescopic tube 4022 is fixedly connected to the bottom of the inner cavity of the top end of the second wiping roller 4021, a positioning block 4023 is fixedly connected to the top of the first spring telescopic tube 4022, and the upper end of the positioning block 4023 is movably connected to the inner wall of the positioning groove 4012.

[0039] Adopting the above solution: Through the cooperation of structures such as the first wiping unit 401 and the second wiping unit 402, pulling the second wiping roller 4021 will drive the positioning block 4023 to move inside the positioning groove 4012. Through the design of multiple positioning grooves 4012, the effect of fixing the second wiping roller 4021 and the first wiping roller 4011 at different positions is realized. By adjusting the distance value between the first wiping unit 401 and the second wiping unit 402, it is suitable for the distance values of different tool presetting instrument detection and presetting positions, increasing the overall applicability.

[0040] As Figure 7 、 Figure 8 and Figure 10As shown in the figure, the protection unit 7 includes a rectangular positioning frame 701. The rectangular positioning frame 701 is fixedly connected to the mounting frame 2. A protection plate 702 is movably connected inside the rectangular positioning frame 701. A magnetic attraction arc block 703 is movably connected inside the protection plate 702. A second spring telescopic tube 704 is fixedly connected to the top of the magnetic attraction arc block 703. The top of the second spring telescopic tube 704 is fixedly connected to the inner wall of the protection plate 702. Both ends of the protection plate 702 are fixedly connected to the movable assembly 9. The bottom surface of the magnetic attraction arc block 703 is arc-shaped. The connection assembly 6 includes a worm 601. The worm 601 is connected to the top end of the protection unit 7 by a bearing. Transmission assemblies 12 are sleeved on both ends of the worm 601. Spring pieces 602 are fixedly connected to both sides of the surface of the worm 601. A protective shell is fixedly installed on the outer surface of the spring pieces 602. The spring pieces 602 are fixedly connected to the protection unit 7 through the protective shell.

[0041] Adopting the above scheme: The top end of the worm 601 is meshed and connected with the gear 503. Through the cooperation of the structures of the worm 601 and the spring pieces 602, the worm 601 will rotate through the transmission assembly 12. After the worm 601 rotates, it will drive the gear 503 to rotate through the middle position thereof, and then drive the entire rotating shaft 501 to rotate. The protective wiping assembly 4 is driven to move through the rotating shaft 501, thereby facilitating the wiping effect of the subsequent protective wiping assembly 4. Through the cooperation of structures such as the rectangular positioning frame 701 and the second spring telescopic tube 704, pulling the protection plate 702 will drive the magnetic attraction arc block 703 to move outwards from the inside of the rectangular positioning frame 701, so that its bottom surface contacts the inside of the lower slide rail of the tool presetting instrument, adsorbing the iron filings in its folding area, ensuring the cleanliness inside the tool presetting instrument during the next use, and preventing its slide rail from being blocked during operation, ensuring the smoothness of the slide rail movement.

[0042] As Figure 13 As shown in the figure, the blowing assembly 8 includes a placement bin 801. The placement bin 801 is fixedly connected to the top of the protection unit 7. Plug blocks 802 are movably sleeved on both sides of the top end of the placement bin 801. An air outlet pipe 803 is fixedly connected to one end of the placement bin 801 away from the mounting frame 2. A baffle 804 is hinged to one end of the air outlet pipe 803 away from the placement bin 801. A first arc-shaped spring telescopic cylinder 805 is fixedly connected to one side wall of the baffle 804 away from the air outlet pipe 803. The end of the first arc-shaped spring telescopic cylinder 805 away from the baffle 804 is fixedly connected to the air outlet pipe 803. The movable assembly 9 includes a first connecting pipe 901. The first connecting pipe 901 is fixedly connected to the blowing assembly 8. A second connecting pipe 902 is fixedly connected to the lower end of the first connecting pipe 901. The second connecting pipe 902 is fixedly connected to the protection unit 7. A piston block 903 is movably sleeved inside the second connecting pipe 902. A C-shaped rod 904 is fixedly installed at one end of the piston block 903 away from the connection assembly 6. The C-shaped rod 904 is fixedly connected to the protection unit 7.

[0043] Adopting the above scheme: The first connecting pipe 901 is communicated with the placement bin 801. One end of the C-shaped rod 904 close to the mounting bracket 2 is fixedly connected to the protection plate 702. Through the cooperation of structures such as the blowing assembly 8 and the moving assembly 9, when the protection unit 7 moves, the piston block 903 will be pulled to move together inside the second connecting pipe 902. At this time, the leather plug 802 is taken out upward from the top of the placement bin 801. Then, external air will enter the inside of the second connecting pipe 902. When the protection unit 7 moves towards the mounting bracket 2, the leather plug 802 is repositioned on the top of the placement bin 801, and the piston block 903 will move backward inside the second connecting pipe 902. At this time, the air inside the second connecting pipe 902 will enter the inside of the air outlet pipe 803. Due to the continuous pushing of the piston block 903, the gas located inside the air outlet pipe 803 will impact the baffle 804, causing the baffle 804 to be in a folded state, so that the air inside the air outlet pipe 803 can be discharged outward. Furthermore, after cleaning the top of the lower slide rail of the tool presetting instrument through multiple air outlet pipes 803, wind blowing is carried out, thereby further improving the cleanliness.

[0044] As Figure 8 Shown in the figure, the limiting unit 10 includes a limiting rubber arc plate 1001. The limiting rubber arc plate 1001 is hinged to the protection unit 7. The upper end of the side wall of the limiting rubber arc plate 1001 away from the protection unit 7 is fixedly connected to a second arc-shaped spring telescopic cylinder 1002. One end of the second arc-shaped spring telescopic cylinder 1002 away from the limiting rubber arc plate 1001 is fixedly connected to the top of the protection unit 7. The positioning assembly 11 includes a rubber gasket 1102. The rubber gasket 1102 is fixedly connected to the protection unit 7. Clamping columns 1103 are fixedly installed at both ends of the rubber gasket 1102. The outer surface of the clamping column 1103 is movably sleeved with a telescopic sleeve 1101. One end of the telescopic sleeve 1101 away from the rubber gasket 1102 is movably clamped to the outer wall of the limiting unit 10.

[0045] Adopting the above scheme: Through the cooperation of the limiting rubber arc plate 1001 and the second arc-shaped spring telescopic cylinder 1002 structures, when the device is placed on the top of the lower slide rail of the tool presetting instrument, at this time, the limiting rubber arc plate 1001 is folded so that its bottom end is connected to the outer wall of the tool presetting instrument, and then a stable positioning effect will be achieved for the device. Rotate the telescopic sleeve 1101 so that it is clamped to the outer wall of the limiting rubber arc plate 1001, thereby realizing the positioning of the lower end of the device with the tool presetting instrument.

[0046] As Figure 9 and Figure 13As shown in the figure, the transmission component 12 includes a circular shaft 1201. The circular shaft 1201 is connected to the protection unit 7. A connecting rope 1202 is movably connected to the outer surface of the circular shaft 1201. The top of the connecting rope 1202 is fixedly connected to the connecting component 6, and the bottom end of the connecting rope 1202 is fixedly connected to the protection unit 7. The outer shape of the air outlet pipe 803 is in an "S" shape, and the bottom opening thereof faces downward. The bottom end of the air outlet pipe 803 is located at the middle position of the protection unit 7.

[0047] With the above solution: Through the limitation of the outer shape of the air outlet pipe 803, the "S" shape is more conducive to the filling and flow of air. The limitation of its low position ensures that when the protection unit 7 moves, it will not block the bottom end of the air outlet pipe 803; Through the cooperation of the structures of the circular shaft 1201 and the connecting rope 1202, the bottom end of the connecting rope 1202 is connected to the protection plate 702, and the top end of the connecting rope 1202 is fixedly connected to the worm 601. When the protection plate 702 moves, it will drive the connecting rope 1202 to move together. At this time, the connecting rope 1202 will drive the worm 601 to rotate, thus facilitating subsequent cooperative use.

[0048] The working principle and usage process of the present invention:

[0049] S1. Place the device on the top of the lower slide rail of the tool presetting instrument. Flip the limiting rubber arc plate 1001 so that the bottom surface of its lower end fits against the outer wall of the tool presetting instrument, and make it fixedly connected to the tool presetting instrument through the elastic force of the second arc spring telescopic cylinder 1002. At the same time, the inner wall of the rubber gasket 1102 will also fit against the outer wall of the tool presetting instrument, so as to realize the positioning function of the device.

[0050] S2. Move the detection module at the upper end of the tool presetting instrument to the same horizontal position as the protection and wiping component 4. At this time, press the positioning block 4023 downward through the positioning groove 4012 so that it moves into the interior of the second wiping roller 4021. Then, according to the interval value between the detection modules on both sides at the upper end of the tool presetting instrument, pull the first wiping roller 4011 and the second wiping roller 4021 so that their outer ends fit against the protective glass on the outer wall of the detection module of the tool presetting instrument, and realize the fixing function of the first wiping roller 4011 and the second wiping roller 4021 through the positioning block 4023 and the positioning groove 4012.

[0051] S3. Pull the protection plate 702 so that the magnetic attraction arc block 703 moves outwards from the interior of the rectangular positioning frame 701. At this time, the magnetic attraction arc block 703 will move downward and fit against the top surface of the protective rubber on the top of the lower slide rail of the tool presetting instrument. At this time, as the protection plate 702 moves, the bottoms of multiple magnetic attraction arc blocks 703 will adsorb the iron filings at the folding part of the protective rubber, so as to achieve the effect of cleaning the iron filings.

[0052] S4. As the protective plate 702 moves, its two ends will drive the piston block 903 to pull outwards inside the second connecting pipe 902. At this time, the leather plug block 802 is pulled out so that air can enter the inside of the second connecting pipe 902. After the bottom of the magnetic adsorption arc block 703 adsorbs the iron filings and moves towards one end of the mounting frame 2, the leather plug block 802 is pressed back into the placement bin 801. At this time, the air inside the second connecting pipe 902 will enter the inside of the first connecting pipe 901, the placement bin 801, and the air outlet pipe 803 through the extrusion of the piston block 903. Due to the continuous application of the extrusion force, the air inside the air outlet pipe 803 will impact the baffle 804, causing the baffle 804 to release the closure of the air outlet pipe 803. At this time, the air will blow towards the top surface of the protective rubber through the air outlet pipe 803, thereby achieving the effect of secondary cleaning. And through the cooperation of the first arc spring telescopic cylinder 805, the reset effect of the baffle 804 will be achieved;

[0053] S5. When the protective plate 702 drives the magnetic adsorption arc block 703 to clean, the protective plate 702 will drive the worm 601 to rotate by pulling the connecting rope 1202. The worm 601 will cause the gear 503 to rotate. The rotation of the gear 503 will drive the first wiping roller 4011 and the second wiping roller 4021 to rotate together through the belt 502. At this time, the first wiping roller 4011 and the positioning groove 4012 will wipe the outer wall protection glass of the tool presetting instrument detection module. Through the cooperation of the above steps, the protection effect of the tool presetting instrument is greatly improved when the tool presetting instrument is not in use.
