[0019] This utility model proposes a pressure holding device 1000.

[0020] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the pressure holding device 1000 includes a frame 1, a pressure holding mechanism and a positioning mechanism 2; the pressure holding mechanism is ellipsably mounted on the frame 1; the positioning mechanism 2 is used to position the workpiece, and the positioning mechanism 2 is movably mounted on the frame 1 so that different pressure-holding parts of the workpiece are moved to the underside of the pressure holding mechanism respectively.

[0021] The frame 1 serves as the supporting foundation. The pressure-holding mechanism is vertically mounted on the frame 1 and moves up and down via hydraulic or electric means to apply pressure to the workpiece. The positioning mechanism 2 is movably mounted on the frame 1 and can clamp and position the workpiece. The positioning mechanism 2 can flexibly adjust its position to accurately place different pressure-holding parts of the workpiece below the pressure-holding mechanism. Taking a long, narrow industrial product as an example, during operation, the workpiece is first placed on the positioning mechanism 2. Using the lateral, longitudinal, or rotational functions of the positioning mechanism 2, one pressure-holding part of the workpiece is aligned with the pressure-holding mechanism. The pressure-holding mechanism descends according to the preset pressure value, contacts the pressure-holding part of the workpiece, and applies pressure. During the pressure-holding process, the pressure is continuously and stably supplied until the preset pressure-holding time is reached. After completion, the pressure-holding mechanism rises, and the positioning mechanism 2 moves the workpiece so that the other pressure-holding parts of the workpiece are aligned with the pressure-holding mechanism, and the pressure-holding operation is repeated.

[0022] In the technical solution of this utility model, the workpiece can be moved by the positioning mechanism 2, so that different parts of the workpiece to be pressured are moved to the bottom of the pressure holding mechanism, thereby segmenting and sequentially pressure holding the workpiece to meet the pressure holding requirements of products with different shapes.

[0023] Specifically, in one embodiment of this utility model, please refer to... Figure 4 The pressure holding device 1000 also includes a drive mechanism, which comprises a rotary drive 3, a rotary motion part 4, and a linear motion part 5 mounted on the frame 1. A drive motor drives the rotary motion part 4 to rotate around a first horizontal direction, and the rotary motion part 4 drives the linear motion part 5 to move along the first horizontal direction. The positioning mechanism 2 is connected to the linear motion part 5. The rotary drive 3 is preferably a servo motor, which is fixedly mounted on the base of the frame 1 via a motor mount. The output shaft of the servo motor is horizontally positioned, and its axial direction is defined as the first horizontal direction. The rotary motion part 4 and the linear motion part 5 are connected by a transmission, enabling the rotary motion of the rotary motion part 4 to be converted into the linear motion of the linear motion part 5, thereby driving the positioning mechanism 2 connected to the linear motion part 5 to perform linear reciprocating motion. The rotary motion part 4 can be a drive gear, which is fixedly mounted on the output shaft of the servo motor. The linear motion part 5 can be a rack meshing with the drive gear, which is fixedly mounted on the base of the frame 1 via fasteners such as a pressure plate, and its length direction is parallel to the first horizontal direction.

[0024] Furthermore, in one embodiment of this utility model, please refer to... Figure 4 The rotary motion part 4 passes through and is threadedly connected to the linear motion part 5. Specifically, the rotary motion part 4 is a precision ball screw, driven directly by the rotary drive 3 or via a coupling, and the linear motion part 5 is a ball screw nut. The screw passes through the nut and engages with its internal ball threads. The positioning mechanism 2 is fixedly connected to the nut via a connecting plate 19.

[0025] Furthermore, in one embodiment of this utility model, please refer to... Figure 4 The drive mechanism also includes a slide rail 6 and a slider 7. The slide rail 6 is mounted on the frame 1, and the slider 7 is slidably mounted on the slide rail 6. The linear motion part 5 is connected to the slider 7. The slide rail 6 is fixedly mounted on the frame 1 by bolts, and its direction is parallel to the first horizontal direction. One or more sliders 7 are nested on the slide rail 6 and can slide freely along it. The linear motion part 5 is fastened to the slider 7 through a connecting plate 19. The precision guiding mechanism composed of the slide rail 6 and the slider 7 can ensure the straightness of the movement trajectory of the positioning mechanism 2. Specifically, in this embodiment, there are two slide rails 6, and two sliders 7 are provided on each slide rail 6.

[0026] Specifically, in one embodiment of this utility model, please refer to... Figure 2 and Figure 5 The pressure-holding mechanism includes a lifting drive component 8, a support plate 9, and a pressure head 10. The lifting drive component 8 is mounted on the frame 1, the support plate 9 is located at the output end of the lifting drive component 8, and the pressure head 10 is located on the side of the support plate 9 facing away from the lifting drive component 8. The lifting drive component 8 is the power source that provides the downward pressure and lifting action required for pressure holding. It is preferably a servo electric cylinder, pneumatic cylinder, or hydraulic cylinder. The cylinder body of this drive component is securely mounted on the crossbeam of the frame 1 by bolts or flanges, and its output shaft is arranged vertically downwards. The support plate 9 is a metal plate with a certain thickness and rigidity, and its top center is rigidly connected to the output end of the lifting drive component 8 by threads or flanges. The pressure head 10 is detachably mounted on the bottom of the support plate 9 by bolts. The shape and size of the pressure head 10 can be designed and replaced according to the specific surface contour of the workpiece to be pressure-held. The working process is as follows: the lifting drive component 8 pushes the support plate 9 and the pressure head 10 below it to move downward; the pressure head 10 contacts the workpiece and applies a preset pressure; during the pressure holding time, the lifting drive component 8 maintains a constant pressure; after the pressure holding time is reached, the lifting drive component 8 drives the support plate 9 and the pressure head 10 to rise and reset.

[0027] To improve the quality of the pressure holding process, please refer to [link / reference]. Figure 5In one embodiment of this utility model, the pressure-holding mechanism further includes a guide plate 11 and a guide rod 12. The guide plate 11 is disposed on the frame 1. The output end of the lifting drive component 8 passes through the guide plate 11 and connects to the support plate 9. The guide plate 11 has a guide hole, and the guide rod 12 passes through the guide hole and connects to the support plate 9. The guide plate 11 is a thick metal plate, which is firmly installed on the frame 1 by bolts or brackets and is located between the lifting drive component 8 and the support plate 9. The guide plate 11 is parallel to the support plate 9. The output end of the lifting drive component 8 extends downward from above, passes through the through hole specially reserved for it on the guide plate 11, and finally connects to the support plate 9 below. An appropriate gap is maintained between the through hole and the output end to ensure no interference. The guide plate 11 is also machined with at least two high-precision guide holes. These guide holes usually have built-in linear bearings or self-lubricating bushings to ensure an extremely low coefficient of friction and high guiding accuracy. At least two guide rods 12 are provided to match the guide hole. The guide rods 12 are rigidly and vertically installed on the side of the support plate 9 opposite to the pressure head 10, i.e., on the upper surface of the support plate 9, via threads or flanges. The precise fit between the guide rods 12 and the guide hole can constrain the support plate 9 to only perform precise vertical linear movements until the pressure head 10 is smoothly pressed against the workpiece surface, thereby improving the quality consistency and reliability of the pressure holding process.

[0028] Furthermore, in one embodiment of this utility model, please refer to... Figure 5 The pressure-holding mechanism also includes a limiting sleeve 13, which is fitted onto the end of the guide rod 12 away from the support plate 9. The limiting sleeve 13 is used to abut against and limit the guide plate 11. The limiting sleeve 13 is a ring-shaped mechanical part, usually made of metal, and is firmly fixed to the end of the guide rod 12. When the lifting drive 8 drives the support plate 9 and the guide rod 12 to move downward, the guide rod 12 will slide downward relative to the guide plate 11. The lower limit position of its movement is determined by the limiting sleeve 13. When the support plate 9 descends to the predetermined position, the limiting sleeve 13 fixed to the upper end of the guide rod 12 will contact the upper surface of the guide plate 11, thereby preventing the entire support plate 9 assembly from continuing to move downward. By mechanically forcibly stopping the downward movement, the risk of deformation, crushing, or damage to the pressure head 10, workpiece, or even the entire support mechanism due to excessive pressure is effectively avoided.

[0029] Specifically, in one embodiment of this utility model, please refer to... Figure 2 and Figure 3The pressure-holding device 1000 also includes a first movable plate 14 and a second movable plate 15. The first movable plate 14 is movably mounted on the frame 1 along a first horizontal direction, and the second movable plate 15 is movably mounted on the first movable plate 14 along a second horizontal direction. The positioning mechanism 2 is mounted on the second movable plate 15. The first and second horizontal directions are orthogonal. The first movable plate 14 is driven by the driving mechanism in the above embodiment, and the first horizontal direction is the axial direction of the output shaft of the rotary drive 3. The second movable plate 15 is located above the first movable plate 14 and can move along the second horizontal direction, specifically through another independent driving mechanism or manually adjusted. Moving along the first horizontal direction changes the position of the workpiece during pressure holding, while moving along the second horizontal direction moves the positioning mechanism 2 and the workpiece from below the pressure head 10 to the loading / unloading station on one side of the equipment for unloading the processed workpiece and installing a new workpiece.

[0030] Furthermore, in one embodiment of this utility model, please refer to... Figure 3 The first movable plate 14 is provided with a first guide rail 141, which extends along a second horizontal direction. The second movable plate 15 is slidably disposed on the first guide rail 141. The pressure holding device 1000 also includes a transfer plate 16, which is disposed on one side of the frame 1. The transfer plate 16 is provided with a second guide rail 161, which extends along a second horizontal direction. The first movable plate 14 has an origin position. At the origin position, the first guide rail 141 and the second guide rail 161 are arranged opposite to each other, so that the second movable plate 15 can slide from the first guide rail 141 to the second guide rail 161. At least one first guide rail 141 is installed on the surface of the first movable plate 14, which extends along the second horizontal direction. The second movable plate 15 is correspondingly provided with a sliding block, so that the second movable plate 15 can slide precisely along the second horizontal direction. The transfer plate 16 is mounted on the frame 1 and positioned near its edge. At least one second guide rail 161 is installed on the platform of the transfer plate 16, extending parallel to the second horizontal direction. The origin is a specific coordinate point of the first movable plate 14. When the first movable plate 14 moves to this preset origin position, its first guide rail 141 and the second guide rail 161 on the transfer plate 16 achieve precise linear alignment. That is, the end faces of the two guide rails are close, and their center lines are perfectly aligned, forming a continuous, stepless track plane. After the track alignment is complete, the second movable plate 15 can smoothly and continuously slide from the first guide rail 141 of the first movable plate 14 to the second guide rail 161 of the transfer plate 16, completing the transfer from inside the equipment to the external platform, and vice versa. Furthermore, to facilitate sliding, the positioning mechanism 2 is equipped with a handle, which allows the positioning mechanism 2 to be pulled to slide the second movable plate 15 along the second horizontal direction.

[0031] Furthermore, in one embodiment of this utility model, please refer to... Figure 3 The pressure-holding device 1000 also includes a stop plate 17, which is disposed on the first movable plate 14 and is used to abut and limit the movement of the second movable plate 15. The stop plate 17 is fixedly installed on the surface of the first movable plate 14 by bolts or direct welding. When the second movable plate 15 moves to a preset end point in the second horizontal direction, its side will make mechanical contact with the stop plate 17, and the movement will be forcibly terminated; this can effectively prevent the second movable plate 15 from overtraveling or derailing.

[0032] Specifically, in one embodiment of this utility model, please refer to... Figure 1 The pressure-holding device 1000 also includes a control panel 18, which is exposed on the frame 1 and electrically connected to the pressure-holding mechanism. The control panel 18 is a human-machine interface integrating a display unit (such as a touchscreen LCD), input units (such as physical buttons and knobs), and indicator units (such as indicator lights and emergency stop buttons), and is positioned at an optimal ergonomic height on the front or side of the frame 1. The electrical connection means that the control panel 18 is connected to the core controller (such as a PLC) of the device via a data cable (such as an Ethernet cable or bus cable). All actuating and feedback components of the pressure-holding mechanism, such as the lifting drive 8 and pressure sensors, are controlled by this core controller.

[0033] In an embodiment of this utility model, the workflow is as follows: Before pressure holding, the required pressure and the required pressure holding time are set via the control panel 18; the workpiece is placed in the positioning mechanism 2, at which time the positioning mechanism 2 and the second movable plate 15 are located on the transfer plate 16; the positioning mechanism 2 and the second movable plate 15 are pushed onto the first movable plate 14 via the handle, and at the same time, the positioning mechanism 2 clamps and positions the workpiece; the driving mechanism drives the first movable plate 14 to move to the first pressure holding point, and the pressure holding mechanism holds the workpiece according to the preset parameters, and resets after pressure holding is completed; the driving mechanism sequentially drives the first movable plate 14 to other pressure holding points, and the pressure holding mechanism repeats the pressure holding and reset actions accordingly, until all pressure holding points have completed pressure holding; after pressure holding is completed, the positioning mechanism 2 releases the workpiece, the positioning mechanism 2 is pulled out, and the workpiece is removed.

[0034] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
