Description

Technical Field

[0001] This application relates to the field of machining auxiliary equipment technology, and in particular to automatic pressing devices. Background Technology

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0055] See Figures 1 to 3 At least one embodiment of this application provides an automatic pressing device 1000, which includes a base 100, a pressing assembly 200, and a reset assembly 300. The pressing assembly 200 includes a pressing member 210 and a pressure driving member 220. The pressing member 210 is movably connected to the base 100, and the pressure driving member 220 is mounted on the base 100 and drivenly connected to the pressing member 210, providing pressure to the pressing member 210 to abut against the workpiece 3000. The reset assembly 300 is mounted on the base 100 and drivenly connected to the pressing member 210. When the pressure driving member 220 stops providing pressure to the pressing member 210, the reset assembly 300 provides a force to the pressing member 210 to separate it from the workpiece 3000.

[0056] The automatic pressing device 1000 according to an embodiment of this application can be used as an auxiliary device to assist in fixing the workpiece 3000 when the fixture 2000 is holding it. The automatic pressing device 1000 is fixed to the fixture 2000 by mounting the base 100 on the side plate 2100 of the fixture 2000. The automatic pressing device 1000 assists in fixing the workpiece 3000, increasing the clamping force on the workpiece 3000 and reducing vibration to meet the needs of machining with large cutting volumes and large feed rates. When the workpiece 3000 does not require auxiliary fixing, the reset assembly 300 separates the pressing member 210 from the workpiece 3000, avoiding contact with the workpiece 3000 and facilitating the loading and unloading of the workpiece 3000.

[0057] See Figure 3 In some embodiments, the pressing member 210 is rotatably connected to the base 100. The pressure driving member 220 is provided with a pressure output end 221, which is used to abut against the pressing member 210 and drive the pressing member 210 to rotate. Specifically, the rotation axis of the pressing member 210 is horizontally set, and the pressing member 210 can swing up and down along the rotation axis. When swinging downward, it can abut against the workpiece 3000 below, and when swinging upward, it can separate from the workpiece 3000. The pressure driving member 220 can apply downward pressure to the pressing member 210 to realize the automatic pressing function. The reset assembly 300 can provide an upward force to separate the pressing member 210 from the workpiece 3000.

[0058] Specifically, in some embodiments, the pressure driving member 220 is configured as a hydraulic cylinder, and the pressure output end 221 is configured as a hydraulic cylinder piston rod. The hydraulic cylinder is vertically arranged, and when the hydraulic cylinder piston rod extends downward, it presses against the pressing member 210 downward, so that the pressing member 210 contacts the workpiece 3000 and continuously applies downward pressure.

[0059] See Figure 3 and Figure 4 In some embodiments, a slide rod 400 is provided on the base 100, and a rotating hole 2113 is provided on the pressing member 210. The pressing member 210 is rotatably connected to the base 100 through the rotating hole 2113. Specifically, the base 100 is provided with two fixing blocks 110, and both ends of the slide rod 400 are fixedly mounted on the fixing blocks 110. The pressing member 210 can rotate on the slide rod 400 when subjected to pressure from the pressure driving member 220. The pressing member 210 can slide on the slide rod 400 when subjected to an axial force along the slide rod 400.

[0060] In some embodiments, shock-absorbing blocks 410 are provided at both ends of the slide bar 400, and the shock-absorbing blocks 410 are used to abut against the pressing member 210. When the pressing member 210 slides on the slide bar 400 to both ends, the pressing member 210 abuts against the shock-absorbing block 410 instead of directly impacting the fixed block 110, thereby further reducing vibration.

[0061] Understandably, the slide bar 400 can also be configured as a linear guide or a linear bearing, as long as it can be rotatably and slidably connected to the pressing member 210.

[0062] In some embodiments, the movable connection between the pressing member 210 and the base can also be configured in other ways, such as allowing the pressing member 210 to slide linearly along a track or groove on the base. This connection method allows the pressing member 210 to translate in one or more directions, thereby realizing the action of pressing and releasing the workpiece 3000. Specifically, a linear guide rail can be installed on the base, and the pressing member 210 can slide by cooperating with the linear guide rail via a slider. Alternatively, a groove can be formed on the base, and a protrusion adapted to the groove can be provided on the pressing member 210, allowing the pressing member 210 to slide within the groove.

[0063] In some embodiments, the pressing member 210 and the base can also be elastically connected, using an elastic element, such as a spring or rubber, to connect the pressing member 210 and the base. When the pressing member 210 is subjected to an external force, the elastic element deforms, thereby enabling the pressing member 210 to move. When the external force disappears, the elastic element returns to its original shape, causing the pressing member 210 to return to its initial position. Specifically, a spring can be installed between the pressing member 210 and the base, with both ends of the spring fixedly connected to the pressing member 210 and the base, respectively. Elastic materials such as rubber pads can also be used to achieve the elastic connection.

[0064] See Figure 3 In some embodiments, the reset assembly 300 includes a first magnetic unit 310, which includes a first magnet 311 and a second magnet 312. The first magnet 311 is mounted on the side wall of the pressing member 210 near the workpiece 3000, and the second magnet 312 is mounted on the base 100 at the position corresponding to the first magnet 311. The first magnet 311 and the second magnet 312 are arranged with the same pole facing each other.

[0065] See Figure 3 and Figure 6 Specifically, the pressing member 210 has a first mounting groove 2115 for the first magnet 311 to be inserted, and the base 100 has a second mounting groove 120 for the second magnet 312 to be inserted, so that the first magnet 311 and the second magnet 312 can be installed discreetly, improving space utilization. The first magnet 311 and the second magnet 312 are opposite each other and generate a repulsive force. This repulsive force causes the pressing member 210 to swing upward and separate from the workpiece 3000 below when the pressure driving member stops providing pressure to the pressing member 210.

[0066] In some embodiments, the reset assembly 300 includes a second magnetic unit 320. The second magnetic unit 320 includes a third magnet 321 and a metal plate 322. The third magnet 321 is mounted on the sidewall of the pressing member 210 away from the workpiece 3000. The metal plate 322, corresponding to the position of the third magnet 321, is mounted on the base 100 and located on the side of the pressing member 210 away from the workpiece 3000. Specifically, the pressing member 210 has a third mounting groove 2116 for embedding the third magnet 321, allowing the third magnet 321 to be concealed and further improving space utilization. There is an attractive force between the third magnet 321 and the metal plate 322. This attractive force causes the pressing member 210 to swing upwards and separate from the workpiece 3000 below when the pressure driving member stops applying pressure to the pressing member 210. The pressure driving member 220 is mounted on the metal plate 322.

[0067] Understandably, the first magnet 311, the second magnet 312, and the third magnet 321 are all strong magnets. Compared to ordinary magnets, strong magnets possess stronger magnetism and can generate a greater magnetic field force. At the same distance, the interaction force between strong magnets or between a strong magnet and the metal plate 322 is greater, enabling more effective attraction or repulsion. Furthermore, strong magnets have better magnetic field stability and are less susceptible to interference from external environmental factors such as temperature and slight vibrations, ensuring stable magnetic force over a longer period. Through the above configuration, the use of strong magnets enhances the working performance and reliability of the automatic pressing device 1000. During machining, the device needs to perform frequent pressing and resetting operations; strong magnets ensure that these actions are completed quickly and accurately, reducing malfunctions or errors caused by insufficient magnetic force. Moreover, the stability of strong magnets ensures that the device's performance is not significantly affected by magnetic attenuation during long-term use, extending the device's lifespan and reducing maintenance costs.

[0068] In the automatic pressing device 1000, when the first magnet 311 and the second magnet 312 are opposite each other with the same poles, a large repulsive force is generated. When the pressure driving component 220 stops providing pressure to the pressing component 210, the pressing component 210 needs to separate from the workpiece 3000. At this time, the repulsive force between the strong magnets can quickly and powerfully push the pressing component 210 upward, so that the pressing component 210 quickly separates from the workpiece 3000, realizing the reset function. This large repulsive force can overcome the friction and other resistance that may exist between the pressing component 210 and the workpiece 3000, ensuring the efficiency and reliability of the reset action. The third magnet 321 cooperates with the metal plate 322. Its strong magnetic force can ensure that the pressing component 210 can be accurately attracted to a specific position when needed, providing sufficient attraction for the position adjustment and positioning of the pressing component 210, ensuring that the pressing component 210 is in the appropriate position under different working conditions, thereby improving the working accuracy and stability of the entire automatic pressing device 1000.

[0069] Referring to 3 and 6, in some embodiments, the pressing member 210 includes a rotating plate 211 and a pressing plate 212. The rotating plate 211 is provided with a first end 2111 and a second end 2112. The first end 2111 is provided with a rotating hole 2113, and the outer wall of the second end 2112 is provided with a first abutting portion 2114 for abutting against the pressure output end 221. The pressing plate 212 is connected to the second end 2112, and the pressing plate 212 is provided with a second abutting portion 2121 for abutting against the workpiece 3000. When the pressure driving member 220 applies pressure, the pressing member 210 rotates about the rotating hole 2113 as an axis, realizing the abutting and separation action with the workpiece 3000. When the piston rod of the hydraulic cylinder extends, it presses against the first abutment part 2114, thereby pushing the rotating plate 211 to rotate. This, in turn, drives the connected pressing plate 212 to move, enabling the pressing plate 212 to press the workpiece 3000, thus achieving the function of pressing and fixing the workpiece 3000. The pressing plate 212 is connected to the second end 2112 of the rotating plate 211 and directly contacts the workpiece 3000. The second abutment part 2121 provided on the pressing plate 212 is in close contact with the workpiece 3000 during operation, applying the pressure transmitted from the rotating plate 211 to the workpiece 3000, thereby fixing the workpiece 3000. The design of the second abutment part 2121 ensures good contact and sufficient friction between the pressing plate 212 and the workpiece 3000, preventing the workpiece 3000 from slipping during the pressing process, and meeting the requirements for fixing the workpiece 3000 during machining with large cutting volume and large feed. The connection between the pressing plate 212 and the rotating plate 211 ensures that the pressing plate 212 can stably follow the rotation when the rotating plate 211 rotates, and accurately transmit the pressure to the workpiece 3000.

[0070] Understandably, different second abutment portions 2121 are designed for different workpieces 3000. For planar workpieces 3000 with regular shapes, a planar second abutment portion 2121 can be used to ensure uniform pressure distribution during pressing. For workpieces 3000 with curved surfaces, a matching curved pressing plate 212 needs to be designed so that the second abutment portion 2121 can fully contact the surface of the workpiece 3000, avoiding excessive or insufficient local pressure. For example, when machining cylindrical workpieces 3000, the second abutment portion 2121 of the pressing plate 212 can be designed as an arc to fit the cylindrical surface. Workpieces 3000 of different sizes require pressing plates 212 of different sizes. Larger workpieces 3000 may require a larger pressing plate 212 to provide sufficient pressing area and pressure; smaller workpieces 3000 can use a smaller pressing plate 212 to avoid the pressing plate 212 exceeding the workpiece 3000's range and affecting the machining operation. If the workpiece 3000 is made of a soft material, a soft material, such as rubber or silicone, can be used in the second contact part 2121 of the pressing plate 212 to prevent damage to the surface of the workpiece 3000 during pressing. For the workpiece 3000 which is made of a harder material, the pressing plate 212 can be made of a metal material with higher hardness to ensure sufficient pressing strength.

[0071] See Figure 6 In some embodiments, the connection between the pressing plate 212 and the rotating plate 211 is provided with an included angle, and the pressing plate 212 extends toward the workpiece 3000.

[0072] With the above-described configuration, an angle is set at the connection between the pressing plate 212 and the rotating plate 211, allowing the pressing plate 212 to form a more reasonable pressing angle when contacting the workpiece 3000. When the pressure driving component 220 pushes the rotating plate 211 to rotate, the pressing plate 212 extends obliquely towards the workpiece 3000, which allows for a larger contact area between the pressing plate 212 and the workpiece 3000 and a more uniform pressure distribution. Different workpieces 3000 have different shapes, and this angle design allows the pressing plate 212 to better conform to the surface of the workpiece 3000. In actual processing, the workpiece 3000 may have various contours, and the angle at which the pressing plate 212 extends towards the workpiece 3000 can be optimized according to common workpiece 3000 shapes. For some workpieces 3000 with a certain degree of inclination or special shape, this angle design ensures that the pressing plate 212 maintains good contact with the workpiece 3000 during the pressing process, improving the fixing effect and meeting diverse processing needs. The structure of the pressing plate 212 extending towards the workpiece 3000 enhances the overall stability of the pressing component 210 mechanically. When the pressing plate 212 abuts against the workpiece 3000, the included angle allows the reaction force on the pressing plate 212 to be more reasonably distributed onto the rotating plate 211, reducing stress concentration caused by pressing and lowering the risk of component damage. During long-term operation, this structural design improves the reliability of the pressing component 210, extends the service life of the automatic pressing device 1000, and reduces maintenance costs.

[0073] Meanwhile, the angle design between the pressing plate 212 and the rotating plate 211 does not obstruct operation when loading and unloading workpiece 3000 before and after processing. When the reset assembly 300 separates the pressing member 210 from the workpiece 3000, the pressing plate 212 naturally lifts away from the workpiece 3000 due to the angle, without obstructing the space for loading and unloading workpiece 3000, making it convenient for operators to quickly load and unload workpiece 3000 and improving processing efficiency.

[0074] Understandably, by setting the pressing plate 212 according to different workpieces 3000 and selecting an appropriate included angle, the pressing device can better fit the surface of the workpiece 3000, ensuring the pressing effect and ensuring that the workpiece 3000 will not be affected by vibration, displacement or other issues during the processing, thus ensuring the processing accuracy and quality.

[0075] See Figure 4 and Figure 5In some embodiments, the automatic pressing device 1000 further includes a displacement avoidance component 500. The displacement avoidance component 500 includes a displacement drive member 510 and a connecting unit 520. The displacement drive member 510 is mounted on the base 100 and has a displacement drive end 511. The displacement drive end 511 is flexibly connected to the pressing member 210 via the connecting unit 520. The displacement drive member 510 drives the pressing member 210 to slide along the slide bar 400 via the connecting unit 520. This arrangement ensures that the displacement drive member 510 can effectively drive the pressing member 210 to move, while also allowing the pressing member 210 a certain amount of room to move during its motion, avoiding component damage or impaired movement caused by rigid connections. The displacement avoidance component 500 enhances the flexibility and adaptability of the automatic pressing device 1000. Before machining workpiece 3000, it can drive the pressing component 210 to a suitable initial position, facilitating the subsequent operation of the pressure-applying drive component 220 and ensuring accurate contact between the pressing component 210 and workpiece 3000. After machining, it can drive the pressing component 210 to move quickly away, facilitating the removal of workpiece 3000. Furthermore, if fine-tuning of the position of the pressing component 210 is required during machining, the displacement avoidance component 500 can also play a role, improving machining accuracy and quality.

[0076] Specifically, the displacement drive 510 is configured as a cylinder, and the displacement drive end 511 is configured as the output shaft of the cylinder. The cylinder is mounted on the outer wall of the fixed block 110, and the fixed block 110 has a through hole 111, through hole 111, through hole 111, allowing the output shaft of the cylinder to extend into the interior of the two fixed blocks 110 for connection with the connecting unit 520. When the cylinder extends or retracts, it can drive the pressing member 210 to slide along the axial direction of the slide rod 400.

[0077] It is understood that the pressure drive 220 and the displacement drive 510, in addition to the devices listed in this embodiment, can also be configured as other power sources, which will not be described in detail here.

[0078] In some embodiments, the connecting unit 520 includes a first connecting member 521 and a second connecting member 522. The first connecting member 521 is mounted on the pressing member 210 and has a connecting groove 5211. The second connecting member 522 is mounted on the displacement driving end 511. The first connecting member 521 includes a connecting rod 5221 and a first limiting portion 5222 and a second limiting portion 5223 disposed on the connecting rod 5221. The connecting rod 5221 is fixedly connected to the displacement driving end 511, and the first connecting member 521 is disposed between the first limiting portion 5222 and the second limiting portion 5223. The first connecting member 521 is movably connected to the connecting rod 5221 through the connecting groove 5211. The first limiting portion 5222 and the second limiting portion 5223 limit the first connecting member 521 axially on the slide rod 400.

[0079] Through the above configuration, the connecting slot 5211 provides conditions for the movable connection between the first connecting member 521 and the connecting rod 5221, allowing the first connecting member 521 to move relative to the connecting rod 5221 within a certain range. This movable connection method ensures that the pressing member 210 can move with the movement of the connecting rod 5221, while also giving the pressing member 210 a certain degree of freedom of movement, avoiding excessive stress during movement due to rigid connection and damage to related components. When the displacement driving member 510 drives the connecting rod 5221 to move, the first limiting part 5222 and the second limiting part 5223 limit the first connecting member 521 in the axial direction of the slide rod 400, preventing the first connecting member 521 from falling off the connecting rod 5221 or moving excessively, ensuring that the pressing member 210 always moves on the predetermined track, and improving the reliability and accuracy of the entire device's movement.

[0080] The automatic pressing device 1000 in this embodiment utilizes a pressure driving component 220 and a displacement avoidance component 500 to collaboratively control the rotating pressing component 210 to complete the pressing and avoidance actions. Specifically, in this application, when the pressure driving component 220 applies pressure, the pressing component 210 presses down stably. When the pressure output end 221 of the pressure driving component 220 retracts, the reset component 300 uses repulsive and attractive forces to reliably separate the pressing component 210 from the workpiece 3000, ensuring a smooth return stroke of the pressing component 210 and enhancing the stability and reliability of the pressing and separating actions on the workpiece 3000. The automatic pressing device 1000 uses the displacement driving component 510 to drive the pressing component 210 to slide left and right to achieve automatic avoidance, meeting the needs of automated production without affecting the picking and placing of the workpiece 3000. During automated production, no additional auxiliary devices or manual intervention are required to complete the picking and placing of the workpiece 3000. The rotating pressing component 210 design in this application makes the entire operation process smoother and more efficient. The pressing component 210 has a compact structure, and its swing-type movement mode occupies little space when realizing the pressing and avoidance functions.

[0081] See Figure 3 In some embodiments, the automatic pressing device 1000 further includes a protective cover 600, which is mounted on the base 100. The protective cover 600 and the base 100 enclose a protective space 610, and at least a portion of the pressing member 210 is located within the protective space 610. Specifically, the protective cover 600 is fixedly connected to the base 100 and also fixedly connected to the metal plate 322 to prevent external iron filings from intruding from the rear of the automatic pressing device 1000, blocking iron filings from entering the protective space 610, protecting the pressing member 210 and other internal components of the device, extending the service life of the device, reducing malfunctions and maintenance costs caused by iron filings intrusion, and ensuring the smooth progress of processing work.

[0082] See Figure 7 and Figure 8In some embodiments, the automatic pressing device 1000 further includes a sliding baffle 700, which is fixedly fitted with the pressing member 210. A first baffle 710 and a second baffle 720 are mounted on the base 100, with the first baffle 710 located above the second baffle 720. A guide groove for the pressing member 210 to move is provided between the first baffle 710 and the second baffle 720, and the sliding baffle 700 is slidably connected between the first baffle 710 and the second baffle 720. When the pressing member 210 slides along the slide rod 400 under the drive of the displacement drive member 510, the sliding baffle 700 also slides along with it to prevent iron filings from intruding from the front of the automatic pressing device 1000.

[0083] With the above configuration, the sliding baffle 700 is fixedly fitted with the pressing member 210, allowing the sliding baffle 700 to closely follow the movement of the pressing member 210. On the base 100, a first baffle 710 and a second baffle 720 are installed vertically, with a guide groove between them for the pressing member 210 to move. The sliding baffle 700 is slidably connected within the guide groove between the first baffle 710 and the second baffle 720, ensuring both smooth sliding of the pressing member 210 on the slide rod 400 and stable sliding of the sliding baffle 700 along the guide groove, always moving synchronously with the pressing member 210. When the pressing member 210 slides along the slide rod 400 under the drive of the displacement drive member 510, the sliding baffle 700, fixedly fitted with it, will slide along with it. During the movement of the pressing component 210, the sliding baffle 700 continuously blocks the gap between the pressing component 210 and the outside environment, preventing iron filings from entering from the front of the automatic pressing device 1000. This effectively avoids damage to the pressing component 210, the slide bar 400, and other internal components caused by iron filings, reduces wear and jamming problems caused by iron filings, ensures the normal operation of the automatic pressing device 1000, extends the service life of the device, and also improves the stability and reliability of the processing.

[0084] See Figure 8 In some embodiments, the automatic pressing device 1000 further includes a sensor 800, which is communicatively connected to the pressing assembly 200. The sensor 800 is used to sense the position information of the pressing member 210, and the pressing assembly 200 drives the pressing member 210 to move according to the position information.

[0085] In some embodiments, the sensor 800 is also communicatively connected to the displacement avoidance component 500.

[0086] With the above settings, during the operation of the automatic pressing device 1000, the pressing component 210 undergoes complex movements under the action of the pressure driving component 220, the reset component 300, and the displacement avoidance component 500, and its position is constantly changing. The sensor 800 can capture the position status of the pressing component 210 in real time, such as determining whether the pressing component 210 has moved to the designated position, whether it is close to the workpiece 3000 and ready to be pressed, or whether it has returned to the standby position after processing. By continuously monitoring the position of the pressing component 210, a data foundation is provided for subsequent precise control. When the sensor 800 detects that the pressing member 210 has not yet reached the predetermined pressing position under the push of the displacement drive member 510, the pressing assembly 200 controls the displacement drive member 510 to continue working, pushing the pressing member 210 to move further. When the pressing member 210 reaches the appropriate position, the sensor 800 feeds back the position information to the pressing assembly 200, which then controls the pressure application drive member 220 to start working, causing the pressing member 210 to press the workpiece 3000. After processing is completed, the sensor 800 detects that the pressure application drive member 220 stops working and the pressing member 210 is lifted, and then transmits this information to the pressing assembly 200, which then controls the displacement drive member 510 to drive the pressing member 210 back to the standby position. This feedback control mechanism based on position information enables the automation and precision of the movement of the pressing component 210, ensuring that the automatic pressing device 1000 can accurately complete the corresponding actions at different working stages, improving the efficiency and quality of the entire processing process, reducing manual intervention, and lowering the risk of operational errors.

[0087] The automatic pressing device 1000 provided in this application operates on the following principle:

[0088] 1. In standby mode, the output shaft of the cylinder retracts, causing the pressing component 210 to be positioned on one side of the automatic pressing device 1000. At this time, due to the force of the reset component 300, the pressing component 210 is lifted.

[0089] 2. The output shaft of the cylinder extends and pushes the pressing part 210 to move to the other side. After the sensor 800 detects that the pressing part 210 is in place, the piston rod of the oil cylinder extends and pushes the pressing part 210 down until the workpiece 3000 is pressed.

[0090] 3. After the product is processed, the piston rod of the hydraulic cylinder retracts, the pressing part 210 is raised, the output shaft of the cylinder retracts, and the pressing part 210 is moved to the standby position.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
