[0039] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0040] A multi-microporous throttling plane air-floating raw material pretreatment clamping device according to an embodiment of the present application will be described below in conjunction with the accompanying drawings.

[0041] like Figure 1-Figure 6 As shown, a multi-microporous throttling plane air flotation raw material pretreatment clamping device according to an embodiment of the present application may include a base plate 1, a support frame 2, a rotating assembly 3, four clamping devices 4, a releasing device 5 and a control end 6, wherein the support frame 2 is arranged on the top of the base plate 1.

[0042] It is understandable that the base plate 1 is first placed on a stable working platform, which is the basic supporting structure of the entire device to ensure the stability of the entire device. Subsequently, the support frame 2 is installed on the top of the base plate 1 to provide a support framework for the subsequent installation of other components.

[0043] The rotating assembly 3 is rotatably disposed on the supporting frame 2 , and the four clamping devices 4 include four clamping assemblies 41 , wherein the four clamping assemblies 41 are respectively disposed on four sides of the top of the rotating assembly 3 .

[0044] It can be understood that the multi-microporous throttling plane air-floating raw material is placed on four clamping devices 4. The four clamping components 41 are respectively arranged on the four sides of the top of the rotating component 3, and the raw material is firmly fixed by the structure of the clamping components 41.

[0045] The release device 5 includes a release component 51, wherein the release component 51 is slidably disposed on one side of the support frame 2, and one end of the release component 51 is movably connected to one side of the four clamping components 41, and the control end 6 is electrically connected to the rotating component 3 and the release component 51, respectively.

[0046] It is understandable that, after the raw material is fixed, the operator sends a command to the rotating assembly 3 through the control terminal 6. The rotating assembly 3 starts to rotate on the support frame 2, driving the four clamping devices 4 fixed with the raw material to rotate synchronously. The control terminal 6 can accurately control the rotation angle and speed of the rotating assembly 3 according to the requirements of the processing technology, so that the raw material is rotated to different processing stations in turn for pre-processing.

[0047] When the raw material at a certain position has completed the pre-processing, the control terminal 6 sends a command to the release device 5. The release component 51 of the release device 5 is slidably arranged on one side of the support frame 2. The release component 51 is actuated, and one end thereof is movably connected to one side of the four clamping components 41, and the corresponding clamping components 41 release the clamping of the raw material through the mechanical structure. In this way, the processed raw material can be easily taken out, and then new raw material to be processed can be put in to start the next round of processing flow.

[0048] During the entire working process, the control terminal 6 plays a key central control role. Through the electrical connection with the rotating component 3 and the loosening component 51, it realizes the automatic control of each action of the device, greatly improving the working efficiency and processing accuracy of the pretreatment of the multi-microporous throttling plane flotation raw materials.

[0049] In one embodiment of the present application, Figure 1-Figure 5 As shown, in an actual working scenario, the operation process of this part of the rotating component 3 is as follows:

[0050] Installation and connection: When assembling the device, the rotating shaft 31 is rotatably mounted on the top of the support frame 2 through rotating connection components such as bearings. This installation method ensures that the rotating shaft 31 can rotate smoothly and flexibly on the support frame 2. Subsequently, the mounting plate 32 is firmly fixed on the top of the rotating shaft 31. The mounting plate 32 is used to carry four clamping devices 4 to provide a position basis for the fixation of raw materials. Finally, the rotating motor 33 is fixed to one side of the support frame 2, and the output end of the rotating motor 33 is connected to the rotating shaft 31 through a coupling and other connecting components, thereby establishing a power transmission path.

[0051] Startup and power transmission: When the rotating assembly 3 needs to work, the control terminal 6 sends a command to start the rotating motor 33. The rotating motor 33 starts to run and outputs torque. Since the output end of the rotating motor 33 is connected to the rotating shaft 31, the rotational power of the motor is transmitted to the rotating shaft 31, driving the rotating shaft 31 to rotate around its own axis.

[0052] Drive the mounting plate and the clamping device to rotate: The rotation of the rotating shaft 31 drives the mounting plate 32 fixed on the top thereof to rotate synchronously. Because the four clamping devices 4 are respectively arranged on the four sides of the top of the mounting plate 32, the rotation of the mounting plate 32 also drives the four clamping devices 4 to rotate in a circle around the axis of the rotating shaft 31. In the pretreatment process of the multi-microporous throttling plane air flotation raw materials, the rotation angle and speed of the mounting plate 32 and the clamping device 4 can be accurately controlled by rotating the motor 33 in the forward and reverse directions and adjusting the speed, so that the raw materials can be rotated to different processing positions in turn to meet different processing requirements.

[0053] In one embodiment of the present application, Figure 1-Figure 2 As shown, in actual operation, four clamping components 41 are responsible for fixing the multi-microporous throttling plane air-floating raw materials, and the working process is as follows:

[0054] Installation in place: During the equipment assembly stage, the mounting seat 411 is fixedly mounted on one side of the top of the mounting plate 32 as the installation base of the entire clamping assembly 41. The stable installation of the mounting seat 411 ensures the stability of subsequent components during operation.

[0055] Raw material placement: The multi-microporous throttling plane air-floating raw material is placed between the mounting seat 411 and the fixed block 412. Since the middle part of the fixed block 412 is movably arranged on one side of the mounting seat 411, the fixed block 412 can rotate or move within a certain range with the movable connection point as the axis.

[0056] Clamping action: After the raw material is placed, the fixed block 412 moves towards the direction close to the raw material under the action of the two springs 414. This is because the two connecting rods 413 are respectively fixed at the two ends of the fixed block 412, and one end of the two springs 414 is respectively connected to the two side walls of the mounting seat 411, and the other end is respectively connected to the two connecting rods 413. When the spring 414 is in a natural state, it will generate a pulling force on the connecting rod 413, thereby driving the fixed block 412 to tightly press the raw material, thereby achieving elastic clamping of the raw material. This elastic clamping method can adapt to raw materials of different sizes. Even if there is a certain tolerance in the size of the raw material, the elastic deformation of the spring 414 can ensure that a stable clamping force is provided to the raw material, ensuring that the raw material will not be displaced during the processing process.

[0057] Stability maintenance during processing: When the raw material rotates with the rotating component 3 and is processed, the clamping component 41 continues to play a role. The spring 414 always maintains a certain elastic force, and the raw material is firmly fixed on the mounting seat 411 through the connecting rod 413 and the fixing block 412, overcoming various external forces generated during the processing, such as cutting force, centrifugal force, etc., to ensure the accuracy and quality of processing.

[0058] Loosen the raw materials: When the processing is completed and the raw materials need to be loosened, the loosening component 51 of the loosening device 5 is actuated to push the fixing block 412 to overcome the elastic force of the spring 414, so that the fixing block 412 moves away from the raw materials, thereby releasing the clamping of the raw materials, making it convenient to take out the processed raw materials and prepare for the next processing operation.

[0059] In one embodiment of the present application, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when the raw material needs to be loosened after processing, the loosening component 51 of the loosening device 5 starts to function, and its working process is as follows:

[0060] Start-up preparation: The fixed plate 511 is pre-fixed on a side wall of the support frame 2 as a support for the installation of other components of the loosening assembly 51. The slide rail 512 is installed on the fixed plate 511 to provide a sliding track for the electric slide 513.

[0061] Sliding propulsion: The control terminal 6 issues a command, and the electric slide 513 starts to slide on the slide rail 512. The electric slide 513 can move stably and accurately along a predetermined direction by virtue of good cooperation with the slide rail 512.

[0062] Contact push: Since the contact block 514 is fixedly arranged on the top of the electric slide 513, the contact block 514 will move with the electric slide 513. The contact wheel 515 is rotatably arranged at one end of the contact block 514, and the contact wheel 515 is movably connected to the lower end of the fixed block 412. When the contact wheel 515 moves with the contact block 514 to contact the lower end of the fixed block 412, the contact wheel 515 that continues to move will push the fixed block 412.

[0063] Release the clamping: The fixed block 412 overcomes the elastic force of the spring 414 and moves away from the raw material under the push of the contact wheel 515, thereby releasing the clamping of the raw material. At this time, the processed raw material can be easily taken out and prepared for the next processing operation.

[0064] In one embodiment of the present application, Figure 1-Figure 5 As shown, when the multi-microporous throttling plane air-floating raw material is placed on the clamping device 4 and fixed, if the rotating component 3 is required to drive the raw material to rotate to the processing station, the operator inputs the corresponding rotation command on the control terminal 6, such as setting the rotating motor 33 to rotate forward, the speed is 10 rpm, and the rotation angle is 90°. After receiving the command, the control terminal 6 converts it into an electrical signal and sends it to the rotating motor 33. The driver of the rotating motor 33 receives the electrical signal, drives the motor to operate according to the set parameters, and the output end of the motor drives the rotating shaft 31 to rotate, thereby causing the mounting plate 32 installed on the top of the rotating shaft 31 to rotate together with the four clamping devices 4 and the raw material.

[0065] When the raw material processing is completed and needs to be released and taken out, the operator inputs the release command on the control terminal 6, and the control terminal 6 converts the command into an electrical signal and sends it to the electric slide 513. Assuming that the electric slide 513 is set to slide forward 50mm at a speed of 50mm / s, after the electric slide 513 receives the electrical signal, its internal drive device starts to work and slides on the slide rail 512 according to the set speed and stroke. Since the contact block 514 is fixed on the top of the electric slide 513, the contact block 514 moves with the electric slide 513, and the contact wheel 515 set at one end of the contact block 514 also moves therewith. When the contact wheel 515 moves to contact with the lower end of the fixed block 412, the contact wheel 515 that continues to move pushes the fixed block 412, so that it overcomes the elastic force of the spring 414 and moves in the direction away from the raw material, thereby releasing the clamping of the raw material.

[0066] In one embodiment of the present application, Figure 2 As shown, when the multi-microporous throttling plane air-floating raw material is placed between the mounting seat 411 and the fixing block 412, and the fixing block 412 approaches and presses the raw material under the action of the two springs 414, the anti-slip rubber layer is in direct contact with the raw material. The surface of the anti-slip rubber layer has special texture and material characteristics, and its rough surface can increase the friction between the raw material and the raw material. Even if the surface of the raw material is relatively smooth, the anti-slip rubber layer can effectively prevent the raw material from sliding between the fixing block 412 and the mounting seat 411 by virtue of its own characteristics, so that the raw material remains stable when it is initially fixed.

[0067] It should be noted that the control method of the present application can be automatically controlled by a controller, and the control method of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field, and the present application is mainly used to protect mechanical structures, so the present application will no longer explain the control method and circuit connection in detail.

[0068] Specifically, the workflow during the actual implementation is as follows:

[0069] When the multi-microporous throttling plane air-floating raw material pretreatment clamping device is actually used, the base plate 1 is first placed on a solid and flat working platform, and then the support frame 2 is installed on the top of the base plate 1 to build the basic frame of the device. Then, the rotating shaft 31 is rotatably installed on the top of the support frame 2 through a bearing, the mounting plate 32 is fixed on the top of the rotating shaft 31, and the rotating motor 33 is fixed on one side of the support frame 2, and its output end is connected to the rotating shaft 31 through a coupling, and the assembly of the rotating component 3 is completed.

[0070] Four mounting seats 411 are respectively fixed on the four sides of the top of the mounting plate 32, and the multi-microporous throttling plane air-floating raw material is placed between the mounting seat 411 and the fixing block 412. Under the action of two springs 414, the fixing block 412 tightly presses the raw material through the connecting rod 413, and uses the anti-slip rubber layer on the fixing block 412 to increase the friction force and firmly clamp the raw material.

[0071] The operator inputs a command on the control terminal 6, such as setting the rotating motor 33 to rotate forward at a speed of 15 rpm and a rotation angle of 180°. The control terminal 6 converts the command into an electrical signal and sends it to the rotating motor 33. The motor drives the rotating shaft 31 to rotate, and the mounting plate 32 and the four clamping devices 4 rotate accordingly, and the raw materials are sent to the processing station.

[0072] When the raw material is processed at this station, the operator inputs a release command at the control terminal 6 again, such as controlling the electric slide 513 to slide forward 40 mm at a speed of 40 mm / s. The control terminal 6 sends the command signal to the electric slide 513, and the electric slide 513 slides on the slide rail 512 on the fixed plate 511, driving the contact block 514 and the contact wheel 515 at the top to move. When the contact wheel 515 contacts the lower end of the fixed block 412, it continues to push the fixed block 412 to overcome the elastic force of the spring 414, so that it is away from the raw material, the clamping is released, the processed raw material is taken out, and the new raw material to be processed is put in, and the above process is repeated for a new round of processing.

[0073] In summary, a multi-microporous throttling plane air flotation raw material pretreatment clamping device in an embodiment of the present application can fix multiple workpieces at the same time by setting four clamping devices, which significantly improves the processing efficiency. The automatic control of the rotating component and the releasing device is realized through the control end to reduce manual intervention. The design of the clamping device and the releasing device ensures the stability of the workpiece during the processing and improves the processing accuracy. Through the cooperation of the rotating component and the releasing device, the workpiece can be quickly fixed and released, and the operation is simple.
