Technical Field
[0001] This utility model relates to the technical field of machine tool dust prevention equipment, specifically a desktop machine tool dust cover that is easy to open and close twice. Background Technology
[0002] A machine tool is a machine used to process metal or other material blanks or workpieces to obtain the required geometry, dimensional accuracy, and surface quality. Machine tools are called "mother machines" or "machine tools" because they are machines that manufacture machines. Benchtop machine tools refer to small machine tools that can be placed on a worktable for operation, mainly including benchtop drilling machines, benchtop milling machines, and benchtop lathes. In applications with high dust levels, machine tools need to be isolated from the external environment to prevent dust accumulation and interference with the operation and accuracy of CNC machine tools.
[0003] In response, Chinese utility model patent CN212470733U discloses a dust cover for CNC machine tools, including a base. Screws are fixedly connected to the middle positions of both sides of the top of the base, and the top of the two screws is fitted with the same dust cover. Two second pulleys are rotatably connected to the inner wall of the top of the dust cover via bearings, and the two screws are threaded to the centers of the two second pulleys. A motor is fixedly connected to the middle position of the outer wall of the top of the dust cover, and the output end of the motor is driven by a coupling to a first pulley. This utility model uses a motor to drive the two second pulleys to rotate. During rotation, the two second pulleys descend along the screws, thereby lowering the dust cover and isolating the CNC machine tool above the base. When the CNC machine tool needs to be moved, the motor is reversed, and the dust cover rises, facilitating operation or transport of the CNC machine tool by the operator.
[0004] The equipment requires the entire dust cover to be moved to operate the machine tool, which is time-consuming and inefficient. Therefore, we propose a benchtop machine tool dust cover that is easy to open and close twice to solve the above problems. Utility Model Content

[0022] Example 1:
[0023] Please see Figure 1-3 This utility model provides a technical solution: a desktop machine tool dust cover that is easy to open and close twice, including a dust cover body 1.
[0024] Please see Figure 1 and Figure 2 The dust cover body 1 has symmetrical mounting blocks 2 fixed to the outer walls on both sides. The mounting blocks 2 are respectively provided with mounting holes 201. The outer wall of the dust cover body 1 is provided with an operation port 101. The top surface of the inner wall of the operation port 101 is provided with a passage 102. The movable baffle 3 is snapped into the passage 102. The bottom surface of the movable baffle 3 contacts the bottom surface of the inner wall of the operation port 101. The bottom surface of the limiting baffle 4 is fixed to the top surface of the movable baffle 3. The bottom surface of the limiting baffle 4 contacts the top surface of the dust cover body 1. The movable baffle 3 is provided with an observation port 301. An observation window 5 is installed in the observation port 301. The operator can use the observation window 5 in the observation port 301 on the movable baffle 3 to check the operation of the machine tool.
[0025] Furthermore, the length of the movable baffle 3 is equal to the length of the operating port 101 and the through port 102, and the thickness of the movable baffle 3 is equal to the width of the through port 102, which facilitates limiting the position of the movable baffle 3.
[0026] Furthermore, the length of the limiting baffle 4 is equal to the length of the dust cover body 1, and the width of the limiting baffle 4 is greater than the width of the passage 102.
[0027] Please see Figure 1 and Figure 2 The dust cover body 1 has an installation port 105 on its top surface, in which a fixed fan 9 is installed. Multiple ventilation ports 106 are evenly distributed on both sides of the outer wall of the dust cover body 1, and dust filters 10 are fixedly connected to each ventilation port 106. The present invention can turn on the fixed fan 9 through the controller 11, which works with the ventilation ports 106 to accelerate the air circulation inside the dust cover body 1 and facilitate heat dissipation. The dust filters 10 installed in the ventilation ports 106 further improve the dustproof effect.
[0028] Please see Figure 1 A controller 11 is provided on the outer wall of the dust cover body 1. This utility model can control the switch of the fixed fan 9 through the controller 11.
[0029] Example 2:
[0030] Please see Figure 1 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment;
[0031] Specifically, a positioning groove 302 is provided on the outer wall of the movable baffle 3. A movable handle 6 is fixedly connected to the outer wall of the movable baffle 3 below the positioning groove 302. A telescopic groove 103 is provided on the inner wall side of the opening 102 near the movable handle 6, corresponding to the positioning groove 302. A fixing hole 104 is provided on the bottom surface of the telescopic groove 103. A movable rod 7 is engaged in the fixing hole 104. A positioning block 701 is fixedly connected to one end of the movable rod 7 near the movable baffle 3. The positioning block 701 is engaged in the telescopic groove 103. The movable rod 7 is away from the movable baffle. One end of the plate 3 is fixed to the moving block 702, and one end of the fixing spring 8 is fixed to the bottom surface of the telescopic groove 103. The other end of the fixing spring 8 is fixed to the positioning block 701. When needed, the moving baffle 3 can be lifted by moving the handle 6. When the positioning groove 302 is aligned with the telescopic groove 103, the positioning block 701 will move away from the telescopic groove 103 under the action of the fixing spring 8 and lock into the positioning groove 302, fixing the position of the moving baffle 3 and opening the operation port 101, making it convenient for the staff to operate the machine tool.
[0032] Furthermore, the diameter of the moving rod 7 is equal to the diameter of the fixing hole 104, the diameter of the positioning block 701 is equal to the diameter of the telescopic groove 103 and the positioning groove 302 respectively, and the diameter of the moving block 702 is greater than the diameter of the fixing hole 104.
[0033] Please see Figures 1 to 3 ;
[0034] In use, the dust cover body 1 is placed over the outside of the benchtop machine tool and fixed in place by the mounting block 2 and mounting hole 201. The operator can observe the machine tool's operation using the observation window 5 inside the observation port 301 on the movable baffle 3. When needed, the movable baffle 3 can be lifted by the movable handle 6, causing the limiting baffle 4 to move upwards. When the positioning groove 302 aligns with the telescopic groove 103, the positioning block 701 will disengage from the telescopic groove 103 and engage in the positioning groove 302 under the action of the fixing spring 8, fixing the position of the movable baffle 3 and opening the operating port 101. The dust cover is designed to be easy for operators to use, eliminating the need to move the entire dust cover body 1. Simply adjusting the position of the movable baffle 3 and operating through the control port 101 reduces dust entry into the dust cover body 1 and minimizes dust contact with the machine tool. The controller 11 can activate the fixed fan 9, which, in conjunction with the vent 106, accelerates airflow within the dust cover body 1, facilitating heat dissipation. The vent 106 contains a dust filter 10, further enhancing dust protection. When the machine tool needs to be moved, the dust cover body 1 can be disassembled for easy repositioning.
