[0048] 1. The present invention sets a dust extraction component. After the amount of dust escape exceeds a predetermined value, the dust reduction effect of spraying cutting fluid by default cannot reach the expected effect, which may cause the dust to scatter and fly to other parts of the equipment.

[0050] 3. The present invention is provided with two rotating plates. On the one hand, it helps to enhance the suction at the entrance after the two rotating plates are in a trumpet shape. When the airflow passes through the gradually narrowing trumpet mouth, according to Bernoulli's principle, the flow velocity increases, resulting in enhanced suction, which helps to more effectively inhale dust and particulate matter. On the other hand, by turning the rotating plate into a trumpet shape, the side on which the dust adheres is made to face the adsorption port, and the adhered dust is adsorbed and collected in the subsequent adsorption process. On the third hand, because the rotating plate is movably connected to the rotating shaft, after the rotating plate is converted into a trumpet shape, the rotating plate itself will shake and vibrate under the action of the airflow, so that the residual dust can be further processed and collected.

[0064] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0065] Application scenario: In the process of turning lenses, in order to control the high temperature generated during the cutting process, it is usually necessary to spray cutting fluid. However, in this process, some dust may escape and spread to other parts of the equipment and accumulate, which may cause damage to the equipment. In order to effectively control dust escape, corresponding measures need to be taken to prevent dust from damaging the equipment.

[0066] like Figures 1 to 12 The diamond ultra-precision single-point turning equipment shown in the figure includes an equipment frame 1, and a cutting component and a cooling component are arranged inside the equipment frame 1. The cutting component is used to turn the target workpiece, and the cooling component is used to spray cutting fluid on the target workpiece during the cutting process. It is characterized in that it also includes:

[0067] The transmission housing 2 is movably arranged inside the equipment frame 1;

[0068] A transmission plate 3 is rotatably connected to the side wall of the transmission housing 2;

[0069] The transmission assembly is arranged inside the transmission housing 2 and is used to drive the transmission disc 3 to rotate;

[0070] A pneumatic chuck 4 is fixedly connected to the side wall of the transmission plate 3 and is used to adsorb and fix the target workpiece;

[0071] Monitoring unit, used to obtain dust escape information;

[0072] The dust extraction component is arranged on the outer wall of the transmission housing 2, and is used to construct a negative pressure space to capture and collect the escaped dust when the monitoring unit obtains that the escaped dust exceeds the standard;

[0073] Specifically, the target workpiece to be turned is placed on the pneumatic chuck 4, and the pneumatic chuck 4 generates an adsorption force through the transmission component to complete the adsorption limit of the target workpiece, and then the target workpiece and the cutting component are adjusted to a suitable position, and then the cutting component and the transmission component are started, and the pneumatic chuck 4 is driven to rotate through the transmission component, and the pneumatic chuck 4 drives the target workpiece to rotate, so that the cutting component cuts the target workpiece. High temperature will be generated in the cutting process, so in this process, the cooling component will also be synchronously controlled to spray liquid to cool the high temperature generated in the working process, and dust will be reduced in the process of spraying cutting fluid when the cutting component cuts the target workpiece;

[0074] At the same time, the amount of dust escape is monitored in real time through the monitoring unit. When the amount of dust escape exceeds the preset value, it is assumed that the dust reduction effect of spraying the cutting fluid cannot reach the expected effect, which may cause the dust to scatter and fly to other parts of the equipment. As the dust flies, it may cause damage to the equipment and even the human body. Therefore, when the amount of dust escape exceeds the preset value, the dust extraction component is controlled to start, and a negative pressure space is constructed in the space above the dust through the dust extraction component, and then the escaped dust is collected into the interior of the dust extraction component by using the pressure difference, so as to prevent the dust from flying and causing damage to the equipment and human body.

[0075] As an optional implementation, the cutting assembly includes existing components such as a cutting seat, a cutting blade and a driving source, which are widely used in various industries and will not be disclosed in detail here.

[0076] It should be noted that the cooling component includes existing components such as a liquid storage tank, a liquid spray pipe and a liquid spray head, which is an existing mature technology and will not be elaborated here one by one.

[0077] The transmission assembly, including existing components such as motors and vacuum pumps, has many applications in the current technical field and will not be elaborated in detail here.

[0078] As a further embodiment, the dust extraction component includes:

[0079] The collecting box 5 is fixedly mounted on the outer wall of the transmission housing 2;

[0080] A negative pressure pump 6 is installed on the collection box 5;

[0081] The collecting cylinder 7 is fixedly mounted on the side wall of the transmission housing 2 and is fixedly connected to the collecting box 5 through a connecting pipe;

[0082] The dust collecting hopper 8 is fixedly connected to the side wall of the collecting tube 7, and a plurality of through holes 9 are formed inside the dust collecting hopper 8;

[0083] Specifically, by controlling the start-up of the negative pressure pump 6, the negative pressure pump 6 will discharge the air inside the collection box 5 to the outside, thereby constructing a negative pressure space inside the collection box 5, and then collecting the escaped dust through the connecting pipe, the collection cylinder 7 and the dust hopper 8. The opening of the dust hopper 8 faces the direction of contact between the cutting assembly and the target workpiece, which helps to better collect the dust.

[0084] As a further embodiment, it also includes:

[0085] The extension tube 10 is slidably connected to the inside of the dust collecting hopper 8;

[0086] A driving unit, disposed on the dust collecting hopper 8, for driving the extension tube 10 to move;

[0087] An extension piece, disposed inside the extension tube 10;

[0088] The electric push rod 11 is fixedly connected to the outer wall of the extension tube 10, and the electric push rod 11 is used to push the extension piece to approach a specified direction;

[0089] Specifically, in the above example, it is mentioned that the escaped dust is collected by constructing a negative pressure space. However, the dust may not only flow and escape, but also enter the gaps between components. If it is not cleaned in time, it may affect the life and working speed of the equipment.

[0090] Therefore, by setting the extension tube 10 and the extension piece, in the initial state, the extension piece is directed toward the transmission disk 3, and after the dust hopper 8 collects dust for a certain period of time, the driving unit is first controlled to drive the extension tube 10 to move, so that the extension tube 10 is connected with the through hole 9 on the dust hopper 8, and then the electric push rod 11 is controlled to push the extension piece toward the transmission disk 3, so that the extension piece absorbs the dust accumulated on the transmission disk 3. At this time, the dust suction port on the extension piece is facing the gap on the transmission disk 3, so that the extension piece is used to absorb the dust in the gap, which helps to reduce the occurrence of dust accumulation in the gap to damage the equipment.

[0091] It should be noted that the drive unit includes a drive motor 12, which is fixedly mounted on the side wall of the dust hopper 8. The output shaft end of the drive motor 12 is fixedly connected to a threaded rod 13, and a threaded seat 14 is fixedly connected to the outer wall of the threaded rod 13. The threaded seat 14 is fixedly connected to the extension tube 10.

[0092] As a further embodiment, the extension piece comprises:

[0093] An extension tube, slidably connected to the interior of the extension tube 10;

[0094] Two shielding covers 16 are symmetrically slidably connected to the ends of the extension tube;

[0095] A connecting frame 17, fixedly connected to the telescopic end of the electric push rod 11;

[0096] Two triangular plates 18, the two triangular plates 18 are symmetrically slidably connected to the two shielding covers 16;

[0097] Two slide grooves 19 are respectively provided on the two triangular plates 18, and the connecting frame 17 is slidably connected between the two triangular plates 18;

[0098] An elastic stretching member 31 is fixedly connected between the two triangular plates 18;

[0099] Two rotating plates 20, both rotating plates 20 are movably connected with rotating shafts 21, the two rotating shafts 21 are rotatably connected to the two shielding covers 16, and the ends of the two rotating shafts 21 are fixedly connected with disks 22, and a torsion spring 23 is fixedly installed between the disk 22 and the shielding cover 16, and the torsion spring 23 is sleeved on the outer wall of the rotating shaft 21;

[0100] A rubber block 24 is fixedly mounted on one of the rotating plates 20, and an adsorption groove 25 is formed on the rubber block 24;

[0101] It should be noted that after the electric push rod 11 is started, it pushes the connecting frame 17 to move, and the connecting frame 17 slides inside the slide groove 19. Because the two triangular plates 18 are limited by the elastic stretching member 31, and because the extension tube is slidably connected to the extension tube 10 and is not limited, the connecting frame 17 will drive the shielding cover 16 to move through the triangular plate 18, and the shielding cover 16 drives the extension tube to slide inside the extension tube 10, so that the shielding cover 16 approaches the direction of the transmission disk 3, and the shielding cover 16 will drive the rubber block 24 to contact the transmission disk 3. After the rubber block 24 contacts the transmission disk 3, the rubber block 24 is deformed by force and fits the side wall of the transmission disk 3, and the adsorption groove 25 contacts the gap on the transmission disk 3, and continuously adsorbs the dust in the gap during the rotation of the transmission disk 3, thereby helping to remove and collect the dust accumulated in the gap on the transmission disk 3;

[0102] After cleaning the gap for a certain period of time, if the dust escape content continues to increase, the extension tube 10 is driven by the driving unit to move toward the cutting position of the cutting assembly and the target workpiece, and then the electric push rod 11 continues to drive the shielding cover 16 to approach the cutting position of the cutting assembly and the target workpiece through the connecting frame 17 and the triangular plate 18. After the extension tube moves to the maximum moving distance inside the extension tube 10, as the electric push rod 11 continues to push the connecting frame 17, the connecting frame 17 slides in the slide groove 19 inside the triangular plate 18, and then the connecting frame 17 pushes the two triangular plates 18 away from each other, and the two triangular plates 18 drive the two shielding covers 16 away from each other, and the two shielding covers 16 drive the rotating plates 20 away from each other through the rotating shaft 21, so that the gap between the two rotating plates 20 will be enlarged at this time, and the two rotating plates 20 will start to expand the dust inlet after approaching the closest distance to the cutting position of the cutting assembly and the target workpiece, which will help the rotating plate 20 to adsorb the specific position where dust is generated during the cutting process, so as to help further reduce the occurrence of escape.

[0103] It should be noted that the elastic stretching member 31 is specifically a sliding sleeve and two elastic telescopic rods. The two elastic telescopic rods are respectively fixedly connected to the two ends of the sliding sleeve, and the telescopic ends of the two elastic telescopic rods are respectively fixedly connected to the two triangular plates 18.

[0104] As a further embodiment, a toothed ring 26 is fixedly mounted on the outer wall of the disc 22, a support column 27 is provided below the shielding cover 16, one end of the support column 27 is fixedly connected to the end of the extension tube 10, and a rack 28 is fixedly mounted on the other end of the support column 27, and the rack 28 is meshed with the toothed ring 26;

[0105] Specifically, the dust accumulated in the gap is adsorbed by the adsorption groove 25, so as to keep the gap clean. However, the gap between the two rotating plates 20 is enlarged to reduce the escape of dust. However, after the two rotating plates 20 move away from each other, some dust will remain on the rotating plates 20 under the action of the airflow.

[0106] In the process of the two rotating plates 20 moving away from each other, the disc 22 will be driven to move through the rotating shaft 21, and the disc 22 will drive the gear ring 26 to rotate. After the gear ring 26 contacts the rack 28, it will drive itself to rotate. The rack 28 drives the rotating shaft 21 to rotate through the disc 22, and the rotating shaft 21 drives the rotating plate 20 to rotate, so that the rotating plate 20 is trumpet-shaped. On the one hand, it helps to enhance the suction at the entrance after the two rotating plates 20 are trumpet-shaped, and when the airflow passes through the gradually narrowing trumpet mouth, according to the Bernoulli principle, the flow rate increases, resulting in enhanced suction, which helps to more effectively inhale dust and particulate matter. On the other hand, by turning the rotating plate 20 into a trumpet shape, the side with dust adhered to it faces the adsorption port, and then the adhered dust is adsorbed and collected in the subsequent adsorption process. On the third aspect, because the rotating plate 20 is movably connected to the rotating shaft 21, after the rotating plate 20 is converted into a trumpet shape, the rotating plate 20 itself will shake and vibrate to a certain extent under the action of the airflow, so that the residual dust can be further processed and collected.

[0107] As a further embodiment, it also includes:

[0108] Two groups of openings 29 are respectively formed on the side walls of the extension tube 10;

[0109] Two sliding shielding plates 30, the two sliding shielding plates 30 are rotatably connected to the two side walls of the extension tube 10 respectively;

[0110] Specifically, in the above example, the dust accumulated in the gap is adsorbed by the adsorption groove 25 to keep the gap clean. However, the gap between the two shielding covers 16 is enlarged to reduce the escape of dust. However, after the two shielding covers 16 are separated from each other, some dust may escape from the extension tube.

[0111] Therefore, when the two shielding covers 16 move away from each other, the two shielding covers 16 will push the two sliding shielding plates 30 to flip, thereby exposing the openings 29. At this time, the dust that wants to escape to the two sides of the extension tube will be adsorbed by the openings 29, thereby expanding the adsorption range to further collect the escaping dust.

[0112] Furthermore, the shielding cover 16 will further shield the dust to help prevent the dust from continuing to fly upward, and is more conducive to the dust being quickly collected through the opening 29.

[0113] As a further implementation, the monitoring unit includes a plurality of dust sensors, and all the dust sensors are distributed inside the transmission housing 2 .

[0114] The dust sensor is fixedly installed inside the transmission housing 2, and the dust is monitored by the dust sensor.

[0115] As a further embodiment, a controller is fixedly installed on the equipment rack 1, and the control method of the controller includes the following steps:

[0116] Acquire first parameter information, where the first parameter information includes dust information;

[0117] generating first control information according to the dust information;

[0118] The first control information is sent to the dust extraction component to control the dust extraction component to perform dust extraction.

[0119] As a further embodiment, it also includes:

[0120] When the first control information is generated, the second control information is also generated;

[0121] The second control information is sent to the driving unit to drive the extension tube 10 to communicate with the through hole 9 .

[0122] As a further embodiment, it also includes:

[0123] generating third control information according to the work completion information of the driving unit;

[0124] The third control information is sent to the electric push rod 11 to push the extension piece toward the specified direction.

[0125] The working principle of the present invention is as follows: the target workpiece to be turned is placed on the pneumatic chuck 4, and the pneumatic chuck 4 generates an adsorption force through the transmission component to complete the adsorption limit of the target workpiece, and then the target workpiece and the cutting component are adjusted to a suitable position, and then the cutting component and the transmission component are started, and the pneumatic chuck 4 is driven to rotate through the transmission component, and the pneumatic chuck 4 drives the target workpiece to rotate, so that the cutting component cuts the target workpiece. High temperature will be generated during the cutting process, so in this process, the cooling component will also be synchronously controlled to spray liquid to cool the high temperature generated during the working process, and dust will be reduced during the process of spraying cutting fluid to reduce the dust generated when the cutting component cuts the target workpiece;

[0126] At the same time, the amount of dust escape is monitored in real time through the monitoring unit. When the amount of dust escape exceeds the preset value, it is assumed that the dust reduction effect of spraying the cutting fluid cannot reach the expected effect, which may cause the dust to scatter and fly to other parts of the equipment. As the dust flies, it may cause damage to the equipment and even the human body. Therefore, when the amount of dust escape exceeds the preset value, the dust extraction component is controlled to start, and a negative pressure space is constructed in the space above the dust through the dust extraction component, and then the escaped dust is collected into the interior of the dust extraction component by using the pressure difference, so as to prevent the dust from flying and causing damage to the equipment and human body.

[0127] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
