Description
Technical Field
[0001] This invention relates to a protective device, and more particularly to a protective device based on a CNC machine tool. Background Technology
[0002] Numerical control machine tools are a type of automated machine tool equipped with a program control system.
[0003] The moving base of existing CNC machine tools usually adopts a structure with a lead screw and nut. Since the chips generated when the machine tool is processing the object are easily splashed onto the lead screw, this will cause the lead screw to wear to a certain extent. For this reason, a retractable protective cover is usually required to cover the outside of the lead screw. However, when a lot of chips remain on the retractable protective cover, it will affect the normal use of the protective cover. Therefore, it is necessary to manually clean the chips remaining on the protective cover from time to time, which is inconvenient and labor-intensive. Summary of the Invention
[0004] To overcome the drawbacks of requiring manual cleaning of debris from the retractable protective cover at regular intervals, which is labor-intensive and inconvenient, this invention provides a protective device based on a CNC machine tool that facilitates debris cleaning.

The control panel is installed on the front side of the operation box. The clamping seat is installed on the rear side wall inside the operation box. The slide rail is fixed to the placement plate. The sliding seat is slidably connected to the slide rail. The workpiece is fixed to the sliding seat. The device also includes a cleaning mechanism for cleaning debris generated during processing and a pushing mechanism for driving the cleaning mechanism.
[0006] Preferably, the cleaning mechanism includes a protective cover, a mounting base, a motor, a fixed base, a lead screw, a nut seat, a sliding frame, a cleaning brush, and rollers. The protective cover is fixed between the slide rail and the sliding seat. The mounting base is fixed to the placement plate. The motor is mounted on the mounting base. The fixed base is fixed to the slide rail. The lead screw is rotatably connected to the right side of the fixed base and the protective cover. The output shaft of the motor is connected to the right end of the lead screw via a coupling. The nut seat is threaded to the lead screw and is fixed to the lower side of the sliding seat. A slide groove is formed on the placement plate. The sliding frame slides in the slide groove. A cleaning brush is fixed to the rear side of the sliding frame. The rollers are rotatably connected to the sliding frame and slide in contact with the upper and lower sides of the placement plate.
[0007] Preferably, the pushing mechanism includes a rack, a rotating rod, a gear, a fixed block, and a push rod. The rack is fixed to the left front side of the sliding seat, the rotating rod is rotatably connected to the placement plate, the gear is fixed to the rotating rod, the rack meshes with the gear, the fixed block is fixed to the middle of the sliding frame, the right end of the push rod is fixed to the rotating rod, and the fixed block is slidably connected to the left side of the push rod.
[0008] Preferably, it also includes a maintenance mechanism, which includes a storage box, a cover, an oil outlet pipe, a baffle plate, a telescopic frame, an elastic element, a guide wheel, and a lever. The storage box is snapped onto the lower side of the sliding seat, the cover is snapped onto the storage box, the oil outlet pipe is connected to and communicates with the bottom wall of the storage box, the baffle plate is slidably connected to the storage box, and a discharge hole is provided on the baffle plate. The telescopic frame is fixedly connected to the baffle plate, the rear end of the telescopic frame is connected to the front side wall of the storage box, an elastic element is sleeved on the telescopic frame, the guide wheel is rotatably connected to the telescopic frame, and the lever is fixedly connected to the slide rail.
[0009] Preferably, it also includes a cooling mechanism, which includes a cooling box, a shielding cover and a water pipe. The cooling box is fixed to the top of the operating box, the shielding cover is installed on the cooling box, and the water pipe is connected to and communicates with the cooling box. The water pipe is located inside the cooling box and the operating box.
[0010] Preferably, it also includes a protective plate, which is fixed to the workpiece.
[0011] Preferably, it also includes an observation window, which is fixed to the left and right side walls of the control box.
[0012] Preferably, it also includes a shielding strip, which is fixed between the slide groove and the slide frame.
[0013] By adopting the above solution, the beneficial effects achieved by the present invention are as follows:
[0014] 1. In this invention, the starting motor drives the lead screw to rotate, thereby driving the nut seat, sliding seat, and workpiece to process the object. After the object is processed, when the nut seat, sliding seat, and workpiece move to the right, the sliding seat drives the rack to move together. The rack moves to the right, causing the gear, rotating rod, and push rod to rotate clockwise. The push rod pushes the fixed block, sliding frame, and cleaning brush to move backward, so that the cleaning brush automatically cleans the debris on the slide rail and protective cover, avoiding excessive debris accumulation that affects the normal use of the protective cover, and helping to achieve the purpose of saving manpower.
[0015] 2. In this invention, the storage box moves together with the sliding seat. When the guide wheel on the storage box contacts the paddle on the slide rail, the paddle pushes the guide wheel to move backward, causing the telescopic frame to retract. The retraction of the telescopic frame will cause the baffle plate to move backward. When the baffle plate moves backward, the discharge hole and the oil outlet pipe are connected. The lubricating oil in the storage box will fall from the connection between the discharge hole and the oil outlet pipe onto the lead screw, which can effectively and automatically apply lubricating oil to the lead screw, which is beneficial for maintaining and protecting the lead screw and nut seat, and thus helps to extend the service life of mechanical parts.
[0016] 3. In this invention, by adding cooling water into the cooling box, the cooling water flows through the water pipe to the milling cutter on the workpiece, which can cool the milling cutter during the processing and prevent the milling cutter from affecting the processing effect due to excessive temperature.
[0017] 4. In this invention, a protective plate is set to prevent debris from splashing, an observation window is set to observe the machine operation inside the control box, and a shielding strip is set to prevent debris from splashing from the chute into the control box below the placement plate.

Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] Example 1
[0031] A protective device based on CNC machine tools, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes an operation box 1, a drain pipe 2, a placement plate 3, a filter plate 4, a protective door 5, a control panel 6, a clamp, a slide rail 8, a sliding seat 9, and a workpiece 10. A drain pipe 2 is connected and communicates with the bottom wall of the operation box 1. The placement plate 3 is bolted to the operation box 1. The filter plate 4 is embedded and snapped onto the placement plate 3. The two protective doors 5 are rotatably connected to the front side wall of the operation box 1. The control panel 6 is installed on the front side of the operation box 1. The clamp is bolted to the rear side wall inside the operation box 1. The clamp is an existing device used to clamp the workpiece to be processed. The slide rail 8 is bolted to the placement plate 3. The sliding seat 9 is slidably connected to the slide rail 8. The workpiece 10 is bolted to the sliding seat 9. The workpiece 10 includes a drive motor and a milling cutter. It also includes a cleaning mechanism 11 for cleaning the debris generated during processing and a pushing mechanism 12 for driving the cleaning mechanism 11.
[0032] like Figure 4 and Figure 5As shown, the cleaning mechanism 11 includes a protective cover 1101, a mounting base 1102, a motor 1103, a fixed base 1104, a lead screw 1105, a nut seat 1106, a sliding frame 1108, a cleaning brush 1109, and rollers 1110. The protective cover 1101 is fixed between the slide rail 8 and the sliding seat 9. The mounting base 1102 is bolted to the placement plate 3. The motor 1103 is mounted on the mounting base 1102. The fixed base 1104 is bolted to the slide rail 8. The lead screw 1105 is connected to the fixed base 1104 and the protective cover 1101. The right side wall is rotatably connected, the output shaft of motor 1103 is connected to the right end of lead screw 1105 through a coupling, nut seat 1106 is threadedly connected to lead screw 1105, nut seat 1106 is bolted to the lower side of sliding seat 9, two sliding grooves 1107 are opened on the placement plate 3, sliding frame 1108 slides in the sliding groove 1107, a cleaning brush 1109 is bolted to the rear side of sliding frame 1108, multiple rollers 1110 are rotatably connected to sliding frame 1108, and rollers 1110 slide in contact with the upper and lower sides of placement plate 3.
[0033] like Figure 6 As shown, the pushing mechanism 12 includes a rack 1201, a rotating rod 1202, a gear 1203, a fixed block 1204, and a push rod 1205. The rack 1201 is bolted to the left front side of the sliding seat 9. The rotating rod 1202 is rotatably connected to the placement plate 3. The gear 1203 is fixedly connected to the rotating rod 1202. The rack 1201 meshes with the gear 1203. The fixed block 1204 is fixedly connected to the middle of the sliding frame 1108. The right end of the push rod 1205 is fixedly connected to the rotating rod 1202. A through groove is provided on the left side of the push rod 1205. The fixed block 1204 slides in the through groove on the left side of the push rod 1205.
[0034] The operator starts the motor 1103 via the control panel 6, which drives the lead screw 1105 to rotate. The rotation of the lead screw 1105 causes the nut seat 1106, sliding seat 9, and workpiece 10 to move to the left, automatically moving the workpiece 10 to the left to process the object on the clamp. As the workpiece 10 moves to the left, the left-side protective cover 1101 folds up, preventing processing debris from splashing onto the lead screw 1105. After processing is complete, the nut seat 1106, sliding seat 9, and workpiece 10 move to the right. The rightward movement of the sliding seat 9 causes the rack 1201 to move as well, and the rack 1201 moves to the right... Gear 1203 and rotating rod 1202 rotate clockwise. When rotating rod 1202 rotates, it drives push rod 1205 to rotate together. The clockwise rotation of push rod 1205 pushes fixed block 1204, sliding frame 1108 and cleaning brush 1109 to move backward. Roller 1110 slides on placement plate 3 at the edge of slide groove 1107. The cleaning brush 1109 moves backward and automatically sweeps the debris on slide rail 8 and protective cover 1101, sweeping the debris onto filter plate 4. Then filter plate 4 is removed and the debris is cleaned, avoiding excessive debris accumulation that affects the normal use of protective cover 1101, which helps to save manpower.
[0035] Example 2
[0036] Based on Example 1, such as Figure 7 , Figure 8 and Figure 9 As shown, it also includes a maintenance mechanism 13, which includes a storage tank 1301, a cover 1302, an oil outlet pipe 1303, a baffle plate 1304, a telescopic frame 1306, an elastic element 1307, a guide wheel 1308, and a lever 1309. The storage tank 1301 is engaged with the lower side of the sliding seat 9, the cover 1302 is engaged with the storage tank 1301, the oil outlet pipe 1303 is connected to and communicates with the bottom wall of the storage tank 1301, and the baffle plate 1304 is engaged with the storage tank 9. The storage box 1301 is slidably connected, and a material discharge hole 1305 is provided on the baffle plate 1304. The lower front part of the telescopic frame 1306 is fixedly connected to the baffle plate 1304, and the rear end of the telescopic frame 1306 is connected to the front side wall of the storage box 1301. An elastic element 1307 is sleeved on the telescopic frame 1306. The elastic element 1307 is a return spring. Two guide wheels 1308 are rotatably connected to the telescopic frame 1306. The lever 1309 is bolted to the slide rail 8.
[0037] When the sliding seat 9 moves left and right on the slide rail 8 to perform processing with the workpiece 10, the storage box 1301 moves with the sliding seat 9. When the guide wheel 1308 on the storage box 1301 contacts the lever 1309 on the slide rail 8, the lever 1309 pushes the guide wheel 1308 to move backward, causing the telescopic frame 1306 to retract backward and the elastic element 1307 to be compressed. The retraction of the telescopic frame 1306 will drive the baffle plate 1304 to move backward. When the baffle plate 1304 moves backward, the discharge hole 1305 is partially connected to the oil outlet pipe 1303. The lubricating oil in the storage box 1301 will fall from the connection between the discharge hole 1305 and the oil outlet pipe 1303 onto the lead screw 1105, which can effectively and automatically apply lubricating oil to the lead screw 1105. This is beneficial for the maintenance and protection of the lead screw 1105 and the nut seat 1106, and thus helps to extend the service life of mechanical parts.
[0038] like Figure 10 As shown, it also includes a cooling mechanism 14, which includes a cooling box 1401, a shielding cover 1402 and a water pipe 1403.

The water pipe 1403 is connected to and communicates with the cooling box 1401. The water pipe 1403 is located inside the cooling box 1401 and the operating box 1.
[0039] The staff opens the cover 1402 and adds cooling water to the cooling box 1401. The cooling water flows through the water pipe 1403 to the milling cutter on the workpiece 10, which can cool the milling cutter during the processing and prevent the milling cutter from affecting the processing effect due to excessive temperature.
[0040] like Figure 4 As shown, it also includes a protective plate 15, which is bolted to the workpiece 10.
[0041] The protective plate 15 is used to prevent debris from flying.
[0042] like Figure 2 As shown, it also includes an observation window 16, which is fixed to the left and right side walls of the control box 1. The observation window 16 is a transparent glass plate.
[0043] The observation window 16 allows staff to observe the operation of the machine inside the control box 1.
[0044] like Figure 4 As shown, it also includes a shielding strip 17, which is fixed between the slide groove 1107 and the slide frame 1108. The shielding strip 17 is made of a soft and foldable material.
[0045] The shielding strip 17 is used to prevent debris from splashing from the chute 1107 into the operating box 1 below the placement plate 3.
