Description

Technical Field

[0001] This utility model belongs to the technical field of CNC machine tool protective covers, and in particular relates to a CNC machine tool protective cover with intelligent sensing dust removal. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. CNC machine tools are generally equipped with protective covers to prevent flying debris generated during the operation of the machine tool from injuring workers.

[0003] For example, the authorized utility model provides a "CNC machine tool protective cover" patent number: 202223076834.X, which includes a first protective cover and a second protective cover. The upper and lower ends of the left side of the second protective cover are respectively connected to a first mounting block and a second mounting block; the upper and lower ends of the right side of the first protective cover are provided with a first mounting groove and a second mounting groove, and the first mounting block and the second mounting block are respectively connected to the inside of the first mounting groove and the second mounting groove. The device has a built-in dehumidifier and a temperature and humidity sensor. The temperature and humidity sensor monitors the internal temperature and humidity in real time. Users can turn on the dehumidifier to reduce the moisture inside the protective cover, effectively preventing the internal equipment or circuits from getting damp and reducing their service life.

[0004] While the aforementioned documents address the issue of existing CNC machine tool protective covers lacking dehumidification capabilities, which makes machine tools and wiring susceptible to moisture corrosion, they still lack intelligent dust removal functionality. The absence of dust removal in these covers leads to long-term dust accumulation on and inside the equipment, accelerating wear on mechanical components. Furthermore, untimely dust removal may cause short circuits or abnormal heat dissipation, ultimately affecting machining accuracy and the machine tool's lifespan. Therefore, we provide a CNC machine tool protective cover with intelligent dust removal functionality to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a CNC machine tool protective cover with intelligent sensing dust removal. Through the cooperation of the movable blade assembly and the dust collection assembly, it solves the problem that the existing CNC machine tool protective covers do not have a dust removal function, which leads to the inability to clean up the dust and debris generated during processing in a timely manner. This results in the accumulation of dust and debris on the surface and inside of the equipment, accelerating the wear of mechanical parts and affecting the processing accuracy.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a CNC machine tool protective cover with intelligent sensing dust removal, comprising a machine tool, a fixed plate fixedly connected to one side of the machine tool's inner cavity, a dust sensor disposed on the top of one side of the fixed plate, a worktable disposed at the bottom of the machine tool's inner cavity, an opening on one side of the machine tool, a protective cover body movably connected to the inner cavity of the opening, a movable blade assembly disposed on one side of the inner cavity of the protective cover body, a dust collection assembly disposed on one side of the movable blade assembly, the movable blade assembly including a fixed frame, the fixed frame being fixedly connected to the inner cavity of the opening on one side of the protective cover body, a swing plate movably connected to the inner cavity of the fixed frame, a swing blade fixedly connected to one side of the swing plate, a drive frame fixedly connected to the other side of the swing plate, a drive shaft movably connected to the inner cavity of the drive frame, a drive rod fixedly connected to one end of the drive shaft, an electric push rod fixedly connected to the top of the protective cover body, and the telescopic shaft of the electric push rod being fixedly connected to the surface of the drive rod.

[0008] The present invention is further configured such that the dust collection assembly includes a dust collection shell, one side of which is fixedly connected to the surface of the protective cover body. A filter frame is provided in the inner cavity of the dust collection shell, and a lifting plate is fixedly connected to the top of the filter frame. A fan shell is fixedly connected to the side of the dust collection shell away from the protective cover body. A motor is provided on one side of the fan shell. The output shaft of the motor passes through the inner cavity of the fan shell and is fixedly connected to a fan blade. When the motor is started, the output shaft of the motor drives the fan blade to rotate. The highly rotating fan blade creates a negative pressure in the inner cavity of the dust collection shell. The protective cover body surrounds the machine tool processing area to form a closed area. Air and dust in the machine tool processing area are drawn into the inner cavity of the dust collection shell, and the filter frame in the inner cavity of the dust collection shell filters out the dust and debris.

[0009] The present invention is further configured such that a support limiting plate is fixedly connected to the bottom of one side of the machine tool, and a through groove is opened on the top of the support limiting plate. A sliding plate is movably connected to the inner cavity of the through groove. The top of the sliding plate is fixedly connected to the bottom of the protective cover body. The sliding plate moves in the inner cavity of the through groove as the protective cover body moves. The size of the inner cavity of the through groove is adapted to the size of the sliding plate so that the protective cover body will not shake when it moves.

[0010] The present invention is further configured such that a receiving frame is fixedly connected to the bottom of the dust collection shell, and a dust collection box is movably connected to the inner cavity of the receiving frame. The dust and debris filtered out by the inner cavity of the dust collection shell fall into the inner cavity of the dust collection box under the action of gravity, and the staff can periodically take out the dust collection box for cleaning.

[0011] The present invention is further configured such that a top plate is fixedly connected to the top of the inner cavity of the passage, and a limiting roller is movably connected to the inner cavity of the top plate. The bottom of the limiting roller contacts the top of the protective cover body. As the protective cover body moves in the inner cavity of the passage, the limiting roller rolls on the top of the protective cover body, thereby limiting the movement of the protective cover body without affecting its normal movement.

[0012] The present invention is further configured such that limiting frames are fixedly connected to both sides of the top of the dust collection shell inner cavity, and movable rollers are movably connected to the inner cavity of the limiting frames. One side of the movable rollers contacts the surface of the filter frame. As the filter frame is inserted into the inner cavity of the dust collection shell, the movable rollers in the inner cavities of the two limiting frames roll on the surface of the filter frame. While limiting the two sides of the filter frame, it does not affect the filter frame entering and exiting the dust collection shell.

[0013] The present invention is further configured such that a ventilation port is provided on one side of the fan housing, and a dustproof net is provided in the inner cavity of the ventilation port. Both external air and air in the machine tool processing chamber can enter and exit through the ventilation port under the action of the high-speed rotating fan blades, and the dustproof net can filter dust in the external air.

[0014] The present invention is further configured such that a clamping rod is movably connected to both sides of the top of the dust collection shell, the bottom of the clamping rod contacts the top of the lifting plate, and by rotating the clamping rod until its bottom contacts the top of the lifting plate, the top of the lifting plate can be clamped and limited, and the filter frame at the bottom of the lifting plate can be fixed in the inner cavity of the dust collection shell.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model has the functions of sensing dust concentration and efficient dust removal. The dust sensor monitors the concentration of dust and debris in the air inside the protective cover in real time. Once the concentration of dust and debris exceeds the standard, the controller immediately starts the motor. The motor drives the fan blades to rotate at high speed, which creates a negative pressure in the inner cavity of the dust collection shell. The dust-laden air in the inner cavity of the main body of the protective cover is quickly sucked into the dust collection chamber and effectively filtered by the filter frame, which greatly reduces the impact of dust and debris on the working environment and machine tool during the processing.

[0017] 2. This utility model has significant advantages in cleaning and maintenance. After the set time, the motor reverses, and a large amount of external air enters the protective cover. At the same time, the electric push rod drives the swing blade to swing, expanding the air blowing coverage area and effectively blowing away the dust on the processing tools, worktable and dust sensor, avoiding dust accumulation that affects the operation of the equipment. In addition, the dust and debris filtered out in the dust collection shell fall into the dust collection box due to gravity. The staff only needs to periodically take out the dust collection box for cleaning, which is simple to operate and reduces the workload and cost of maintenance. Attached Figure Description

[0026] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1

[0028] Please see Figure 1-6This utility model is a CNC machine tool protective cover with intelligent sensing dust removal, including a machine tool 1. A fixing plate 2 is fixedly connected to one side of the inner cavity of the machine tool 1. A dust sensor 3 is installed on the top of one side of the fixing plate 2. A worktable 4 is installed at the bottom of the inner cavity of the machine tool 1. An opening 5 is opened on one side of the machine tool 1. A protective cover body 6 is movably connected to the inner cavity of the opening 5. A movable blade assembly 7 is installed on one side of the inner cavity of the protective cover body 6. A dust collection assembly 8 is installed on one side of the movable blade assembly 7. The movable blade assembly 7 includes a fixing frame 701. 1. The inner cavity of the protective cover body 6 with an opening on one side is fixedly connected. The inner cavity of the fixed frame 701 is movably connected to the swing plate 702. One side of the swing plate 702 is fixedly connected to the swing blade 703. The other side of the swing plate 702 is fixedly connected to the drive frame 704. The inner cavity of the drive frame 704 is movably connected to the drive shaft 705. One end of the drive shaft 705 is fixedly connected to the drive rod 706. The top of the protective cover body 6 is fixedly connected to the electric push rod 707. The telescopic shaft of the electric push rod 707 is fixedly connected to the surface of the drive rod 706.

[0029] Specifically: When dust sensor 3 detects a high concentration of dust and debris in the machining chamber of machine tool 1, it transmits a signal to the controller on machine tool 1. The controller then activates motor 805, causing the output shaft of motor 805 to drive fan blade 806 to rotate at high speed. The high rotation of fan blade 806 creates negative pressure inside the dust collection chamber 801, drawing dust-laden air from the machining chamber into the dust collection chamber. The filter frame 802 inside the dust collection chamber filters out the dust and debris. After a set time, the controller reverses the rotation of motor 805, causing the output shaft of motor 805 to drive fan blade 806 to rotate at high speed in the opposite direction, drawing a large amount of external air into the dust collection chamber. The dust from the inner cavity of the dust shell 801 then enters the inner cavity of the protective cover body 6. At the same time, the electric push rod 707 is opened. The telescopic shaft of the electric push rod 707 drives the drive rod 706 to move up and down. The drive rod 706 drives the drive shaft 705 to move in the inner cavity of the drive frame 704, which in turn drives the swing plate 702 to swing in the inner cavity of the fixed frame 701. The swing plate 702 drives the swing blade 703 to swing up and down. Through the up and down swing of the swing blade 703, the wind blowing from one side of the protective cover body 6 towards the machining chamber of the machine tool 1 can cover a larger space and blow away the dust on the machining tools, the worktable 4, and the dust sensor 3.

[0030] Example 2

[0031] Please see Figure 1-6Based on Embodiment 1, the dust collection assembly 8 includes a dust collection shell 801. One side of the dust collection shell 801 is fixedly connected to the surface of the protective cover body 6. A filter frame 802 is provided in the inner cavity of the dust collection shell 801. A lifting plate 803 is fixedly connected to the top of the filter frame 802. A fan shell 804 is fixedly connected to the side of the dust collection shell 801 away from the protective cover body 6. A motor 805 is provided on one side of the fan shell 804. The output shaft of the motor 805 passes through the inner cavity of the fan shell 804 and is fixedly connected to a fan blade 806. A support limiting plate is fixedly connected to the bottom of one side of the machine tool 1. A through groove is opened at the top of the support limiting plate. A sliding plate is movably connected to the inner cavity of the through groove. The top of the sliding plate is connected to... The bottom of the protective cover body 6 is fixedly connected to a receiving rack, the bottom of the dust collection shell 801 is fixedly connected to a receiving rack, the inner cavity of the receiving rack is movably connected to a dust collection box, the top of the inner cavity of the opening 5 is fixedly connected to a top plate, the inner cavity of the top plate is movably connected to a limiting roller, the bottom of the limiting roller is in contact with the top of the protective cover body 6, the two sides of the top of the inner cavity of the dust collection shell 801 are fixedly connected to limiting frames, the inner cavity of the limiting frames is movably connected to a movable roller, one side of the movable roller is in contact with the surface of the filter frame 802, a ventilation opening is opened on one side of the fan shell 804, the inner cavity of the ventilation opening is provided with a dustproof net, the two sides of the top of the dust collection shell 801 are movably connected to a pressing rod, the bottom of the pressing rod is in contact with the top of the lifting plate 803.

[0032] Specifically: The motor 805 is started, and its output shaft drives the fan blades 806 to rotate. The highly rotating fan blades 806 create negative pressure inside the dust collection housing 801. The protective cover body 6 surrounds the processing area of ​​the machine tool 1, forming a closed area. Air and dust within the processing area of ​​the machine tool 1 are drawn into the inner cavity of the dust collection housing 801. The filter frame 802 inside the dust collection housing 801 filters out the dust and debris. The sliding plate moves within the cavity of the through slot as the protective cover body 6 moves. The size of the through slot cavity matches the size of the sliding plate, preventing the protective cover body 6 from shaking during movement. The dust and debris filtered out by the dust collection housing 801 fall into the inner cavity of the dust collection box under gravity. The dust collection box can be cleaned periodically by the operator. As the protective cover body 6 moves within the cavity of the through-hole 5, the limited... The positioning roller rolls on top of the protective cover body 6, limiting the protective cover body 6 without affecting its normal movement. As the filter frame 802 is inserted into the inner cavity of the dust collection shell 801, the movable rollers in the inner cavities of the two limiting frames roll on the surface of the filter frame 802, limiting both sides of the filter frame 802 without affecting its entry and exit from the dust collection shell 801. External air and air in the processing chamber of the machine tool 1 can enter and exit through the ventilation port under the action of the high-speed rotating fan blade 806, and the dustproof net can filter the dust in the external air. Rotate the clamping rod until its bottom contacts the top of the lifting plate 803, and the top of the lifting plate 803 can be clamped and limited, fixing the filter frame 802 at the bottom of the lifting plate 803 in the inner cavity of the dust collection shell 801.

[0033] The working principle of this utility model is as follows: After the workpiece is fixed on the worktable 4, the protective cover body 6 is pushed so that one side of the protective cover body 6 is pressed tightly against the surface of the fixing plate 2, and processing begins. During the processing of the workpiece, dust and debris will be generated. The dust sensor 3 senses the concentration of dust and debris in the air inside the protective cover body 6. When the concentration exceeds the set value, the controller automatically turns on the motor 805. The output shaft of the motor 805 drives the fan blade 806 to rotate at high speed. The high rotation of the fan blade 806 creates a negative pressure in the inner cavity of the dust collection shell 801. The dust-laden air in the processing chamber of the machine tool 1 is drawn into the inner cavity of the dust collection shell. The filter frame 802 in the inner cavity of the dust collection shell filters out the dust and debris. After the set time, the controller controls the motor 805 to reverse. The output shaft of the motor 805 drives the fan blade 806 to rotate in the opposite direction at high speed. A large amount of air is drawn into the inner cavity of the dust collection shell 801 and then into the inner cavity of the protective cover body 6. At the same time, the electric push rod 707 is opened. The telescopic shaft of the electric push rod 707 drives the drive rod 706 to move up and down. The drive rod 706 drives the drive shaft 705 to move in the inner cavity of the drive frame 704, which in turn drives the swing plate 702 to swing in the inner cavity of the fixed frame 701. The swing plate 702 drives the swing blade 703 to swing up and down. Through the up and down swing of the swing blade 703, the air blown from one side of the protective cover body 6 to the processing chamber of the machine tool 1 can cover a larger space, blowing away the dust on the processing tools, worktable 4 and dust sensor 3. The dust and debris filtered out by the inner cavity of the dust collection shell 801 fall into the inner cavity of the dust collection box under the action of gravity. The staff can regularly remove the dust collection box for cleaning.
