Description

Technical Field

[0001] This utility model relates to the technical field of protective covers for CNC lathes, specifically a CNC lathe protective cover door that can be quickly disassembled. Background Technology

[0002] In the long-term application of CNC lathes, traditional protective doors mostly use bolt fastening or complex locking methods. This design requires operators to spend a significant amount of time using tools to disassemble and reassemble during actual maintenance, tool changes, and debris removal, severely impacting equipment production efficiency and continuity. Frequent disassembly and reassembly not only increases the labor intensity of workers but also extends maintenance windows. Furthermore, repeated tightening of bolts can easily cause thread wear, posing a risk of decreased door positioning accuracy or poor sealing. Therefore, the market urgently needs a protective door structure that allows for quick, tool-free disassembly and reassembly to meet the efficient and flexible production needs of modern manufacturing.

[0003] Existing CNC lathe protective doors make it difficult to clean the observation window during use, making it difficult for operators to monitor the internal processing status in real time without interrupting equipment operation. This increases the safety risks and equipment wear caused by unnecessary door openings.

[0004] In view of this, we propose a quick-detachable protective cover for CNC lathes. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-detachable protective cover for CNC lathes. This quick-detachable protective cover solves the problem of difficulty in cleaning the observation window during use, which makes it difficult for operators to monitor the internal processing status in real time without interrupting equipment operation, and increases the safety risks and equipment wear caused by unnecessary door opening.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-detachable protective cover for a CNC lathe includes a machining device. The machining device includes a base, a control console fixedly connected to the top of the base, a machining table fixedly connected to one side of the control console, and a limit plate fixedly connected to the end of the machining table away from the control console. A sliding groove is formed on the top of the base and slidably connected to the protective cover. An observation window is formed on the protective cover. The device also includes a cleaning device for cleaning the observation window and a lubrication device for lubricating the sliding groove on the base. The cleaning device includes a lead screw, one end of which is fixedly connected to a circular plate.

[0008] Preferably, the cleaning device includes a motor, a lead screw is fixedly connected to the output shaft of the motor, a threaded sleeve is fitted on the circumferential surface of the lead screw, a fixed block is rotatably connected to the end of the lead screw away from the motor, a sliding groove is formed at the end of the threaded sleeve away from the lead screw, and a connecting plate is slidably connected thereto, a spring is fixedly connected to the bottom of the connecting plate, a scraper is fixedly connected to the end of the connecting plate near the spring, a slider is fixedly connected to the end of the connecting plate away from the threaded sleeve, a long plate is slidably connected to the end of the slider away from the connecting plate, a torsion spring rod is rotatably connected inside the long plate, the torsion spring rod passes through an inclined plate and is rotatably connected to the inclined plate.

[0009] Preferably, the motor is fixedly connected to the inner wall of the protective cover door, the long plate has a sliding groove and is slidably connected to the slider, the end of the fixing block away from the lead screw is fixedly connected to the inner wall of the protective cover door, the end of the lead screw away from the motor passes through the fixing block and is rotatably connected to the fixing block, and the lead screw and the threaded sleeve are internally meshed with each other.

[0010] Preferably, the lubrication device includes a circular plate, a cylindrical plate fixedly connected to one side of the circular plate, a rectangular plate rotatably connected to the circumferential surface of the cylindrical plate, a limit block passing through the end of the rectangular plate away from the cylindrical plate and slidably connected to the limit block, a pressing plate fixedly connected to the end of the rectangular plate away from the limit block, an airbag provided at the end of the pressing plate away from the rectangular plate, a fixing plate fixedly connected to the bottom of the airbag, a baffle fixedly connected to the circumferential surface of the airbag, and a pipe fixedly connected to the end of the airbag away from the fixing plate.

[0011] Preferably, the end of the limiting block away from the rectangular plate is fixedly connected to the inner wall of the protective cover door, one end of the fixing plate is fixed to the inner wall of the protective cover door, and the pipe passes through the protective cover door and is fixedly connected to the protective cover door.

[0012] Preferably, the bottom of the baffle is fixedly connected to the fixing plate, and the outlet of the pipe faces the groove set on the base.

[0013] Preferably, the protective cover door is slidably connected to the processing table, and the bottom of the limiting plate is fixedly connected to the base.

[0014] By employing the above technical solution, this utility model provides a quickly detachable protective cover for CNC lathes. It possesses at least the following beneficial effects:

[0015] (1) After the motor is started, the screw is driven to rotate, causing the threaded sleeve that meshes with it to move horizontally along the axial direction. The threaded sleeve drives the connecting plate and the slider fixed on it to move synchronously through the slide groove at its end. The slider slides in the slide groove opened in the long plate. The inside of the slide groove is a movable inclined plate. When the slider moves along the groove to the inclined plate area, its movement trajectory is guided by the groove wall, which applies a force to the inclined plate, forcing it to rise around the hinge point, thereby pulling the scraper at the bottom of the connecting plate upward and separating it from the surface of the processing table, completing one work cycle. The spring set between the connecting plate and the scraper provides the power for the connecting plate to reset in this process, ensuring that the connecting plate descends smoothly in the slide groove of the long plate, achieving the cleaning of the observation window, and ensuring that the operator can keep abreast of the internal processing status without interrupting the operation of the equipment, reducing the safety risks and equipment wear caused by unnecessary opening of the door.

[0016] (2) In this invention, a circular plate is rotated by a lead screw, which in turn drives a cylindrical plate fixedly connected to it to rotate synchronously. The circumferential surface of the cylindrical plate is rotatedly connected to one end of the rectangular plate, thereby converting the rotational motion of the circular plate into the planar oscillation of the rectangular plate. A pressing plate is fixedly connected to the end of the rectangular plate. When the rectangular plate is driven to move towards the fixed plate, the pressing plate applies pressure to the airbag fixed on the fixed plate. Under pressure, the lubricating oil stored inside the airbag is discharged quantitatively through a pipe fixedly connected to its outlet end. This pipe passes through and is fixed to the protective cover. The outlet of the pipe is precisely aligned with the groove on the base, so that the discharged lubricating oil can be directly and concentratedly sprayed onto the key friction pair surface of the sliding connection between the protective cover and the processing table, thereby achieving precise and automated lubrication and effectively ensuring the smooth operation and long-term precision maintenance of the sliding parts.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A quick-detachable protective cover for CNC lathes, such as... Figure 1 - Figure 5 As shown, the processing device 1 includes a base 101, a control console 102 fixedly connected to the top of the base 101, a processing table 103 fixedly connected to one side of the control console 102, a limit plate 104 fixedly connected to the end of the processing table 103 away from the control console 102, a sliding groove provided at the top of the base 101 and slidably connected to a protective cover door 105, and an observation window 106 provided on the protective cover door 105; it also includes a cleaning device 2 for cleaning the observation window 106; and a lubrication device 3 for lubricating the sliding groove on the base 101; the cleaning device 2 includes a lead screw 202, one end of which is fixedly connected to a circular plate 301.

[0028] The cleaning device 2 includes a motor 201. A lead screw 202 is fixedly connected to the output shaft of the motor 201. A threaded sleeve 203 is fitted on the circumferential surface of the lead screw 202. A fixing block 204 is rotatably connected to the end of the lead screw 202 away from the motor 201. A sliding groove is formed on the end of the threaded sleeve 203 away from the lead screw 202, and a connecting plate 205 is slidably connected thereto. A spring 206 is fixedly connected to the bottom of the connecting plate 205. A scraper 207 is fixedly connected to the end of the connecting plate 205 near the spring 206. The scraper 207 is located on the end of the connecting plate 205 away from the threaded sleeve 202. One end of the sleeve 203 is fixedly connected to a slider 208. The end of the slider 208 away from the connecting plate 205 is slidably connected to a long plate 209. A torsion spring rod 211 is rotatably connected inside the long plate 209. The torsion spring rod 211 passes through an inclined plate 210 and is rotatably connected to the inclined plate 210. The above design allows the sliding groove to be opened at the end of the threaded sleeve 203 away from the lead screw 202, and the connecting plate 205 to be slidably connected. This enables the movement of the slider 208 on the long plate 209 to drive the connecting plate 205 to move up and down.

[0029] The motor 201 is fixedly connected to the inner wall of the protective cover door 105. The long plate 209 has a sliding groove and is slidably connected to the slider 208. The end of the fixed block 204 away from the lead screw 202 is fixedly connected to the inner wall of the protective cover door 105. The end of the lead screw 202 away from the motor 201 passes through the fixed block 204 and is rotatably connected to the fixed block 204. The lead screw 202 and the threaded sleeve 203 are internally meshed with each other. The above design, through the internal meshing of the lead screw 202 and the threaded sleeve 203, enables the rotation of the lead screw 202 to be converted into the axial horizontal movement of the threaded sleeve 203.

[0030] The protective door 105 is slidably connected to the processing table 103, and the bottom of the limiting plate 104 is fixedly connected to the base 101. The above design, through the slidable connection between the protective door 105 and the processing table 103, can limit the range of motion of the protective door 105 and provide it with a precise endpoint position.

[0031] Example 2

[0032] like Figure 1 - Figure 6As shown, the lubrication device 3 includes a circular plate 301. A cylindrical plate 302 is fixedly connected to one side of the circular plate 301. A rectangular plate 303 is rotatably connected to the circumferential surface of the cylindrical plate 302. A limiting block 304 passes through the rectangular plate 303 away from the cylindrical plate 302 and is slidably connected to the limiting block 304. A pressing plate 305 is fixedly connected to the rectangular plate 303 away from the limiting block 304. An airbag 306 is provided at the end of the pressing plate 305 away from the rectangular plate 303. A fixing plate 307 is fixedly connected to the bottom of the airbag 306. A baffle 308 is fixedly connected to the circumferential surface of the airbag 306. A pipe 309 is fixedly connected to the end of the airbag 306 away from the fixing plate 307. The above design, by having the limiting block 304 pass through the rectangular plate 303 away from the cylindrical plate 302 and is slidably connected to the limiting block 304, can effectively limit the radial displacement or torsion that may occur in the rectangular plate 303 during movement, ensuring that it always moves smoothly along the preset axial trajectory.

[0033] The end of the limiting block 304 away from the rectangular plate 303 is fixedly connected to the inner wall of the protective door 105. One end of the fixing plate 307 is fixed to the inner wall of the protective door 105. The pipe 309 passes through the protective door 105 and is fixedly connected to the protective door 105. The above design, through the pipe 309 passing through the protective door 105 and being fixedly connected to the protective door 105, enables the pipe 309 to move synchronously with the protective door 105, fundamentally avoiding the problems of pipe entanglement, excessive bending or wear caused by repeated opening and closing of the door.

[0034] The bottom of the baffle 308 is fixedly connected to the fixed plate 307, and the outlet of the pipe 309 faces the groove provided on the base 101. The above design, by having the outlet of the pipe 309 face the groove provided on the base 101, allows the lubricating oil to act directly on the movement track of the protective cover door 105 without any waste, ensuring the smooth operation and long-term accuracy of the sliding parts.

[0035] In use, the quick-detachable CNC lathe protective cover of this utility model is first started by motor 201, which drives lead screw 202 to rotate, causing threaded sleeve 203 to move horizontally along the axial direction. The threaded sleeve 203 drives connecting plate 205 and slider 208 fixed thereon to move synchronously through a groove at its end. The slider 208 slides within a groove opened in long plate 209. Inside the groove is a rotatable inclined plate 210. When the slider 208 moves along the groove to the area of ​​inclined plate 210, its trajectory is guided by the groove wall, applying a force to the inclined plate 210, forcing it to rise around torsion spring rod 211. As the slider 208 continues to advance and passes under the inclined plate 210, the inclined plate 210 descends and resets under the torque assistance of the torsion spring rod 211. This descent forces the slider 208 to move upward along the inclined plate 210 into the groove, thereby pulling the scraper 207 at the bottom upward through the connecting plate 205, separating it from the surface of the observation window 106, completing one work cycle. The spring 206 between the connecting plate 205 and the scraper 207 provides the resetting power for the connecting plate 205 during this process, ensuring that the connecting plate 205 descends smoothly in the groove of the long plate 209, achieving the cleaning of the observation window 106. This ensures that the operator can monitor the internal processing status in real time without interrupting the equipment operation, reducing the safety risks and equipment wear caused by unnecessary door opening. At the same time, the lead screw 202 drives the circular plate 301 to rotate, which in turn drives the cylindrical plate 302 fixedly connected to it to rotate synchronously. The circumferential surface of the cylindrical plate 302 is rotatably connected to one end of the rectangular plate 303, thereby converting the rotational motion of the cylindrical plate 301 into the planar oscillation of the rectangular plate 303. A pressing plate 305 is fixedly connected to the end of the rectangular plate 303. When the rectangular plate 303 is driven to move towards the fixed plate 307, the pressing plate 305 applies pressure to the airbag 306 fixed on the fixed plate 307. Under pressure, the lubricating oil stored inside the airbag 306 is metered out through a pipe 309 fixedly connected to its outlet end. This pipe 309 passes through and is fixed to the protective cover 105. The outlet of the pipe 309 is precisely aligned with the groove on the base 101, allowing the discharged lubricating oil to be sprayed directly and concentrated onto the key friction pair surfaces where the protective cover 105 and the processing table 103 slide, thus achieving precise and automated lubrication and effectively ensuring the smooth operation and long-term precision maintenance of the sliding components.
