The pressing cylinder is fixedly connected to the connecting plate. A buffer device is provided on the top of the column, and the buffer device is connected to the connecting plate for driving the connecting plate to move vertically.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0034] Please refer to Figures 1 to 6 The present invention provides a shell pressing device for pressing an upper shell 1 and a lower shell 2 into a complete shell. The shell pressing device includes: a base 3, a column 4, a pressing cylinder 5, an elastic element 6, a first connecting rod 7, a second connecting rod 8, a first pressing plate 9 for fixing the lower shell 2, and a second pressing plate 10 for fixing the upper shell 1.

[0035] Specifically, the first pressing plate 9 and the column 4 are both mounted on the base 3. The pressing cylinder 5 is connected to the column 4 and located above the first pressing plate 9. The piston 51 of the pressing cylinder 5 faces downward toward the first pressing plate 9. The lower end of the piston 51 is connected to one end of the first connecting rod 7 and to one end of the second connecting rod 8 through the elastic element 6. The other ends of the first connecting rod 7 and the second connecting rod 8 are both connected to the second pressing plate 10, so that the second pressing plate 10 is inclined relative to the first pressing plate 9. The piston 51 is used to drive the second pressing plate 10 to press onto the first pressing plate 9 in sections through its own extension and retraction, so as to realize the segmented pressing between the upper shell 1 and the lower shell 2.

[0036] Understandably, since piston 51 is connected to the second connecting rod 8 via elastic element 6, the stroke of piston 51 connecting to the second pressing plate 10 via the second connecting rod 8 is longer than the stroke of piston 51 connecting to the second pressing plate 10 via the first connecting rod 7. This causes the second pressing plate 10 to be initially tilted, meaning the side of the second pressing plate 10 corresponding to the second connecting rod 8 is closer to the first pressing plate 9, and the side of the second pressing plate 10 corresponding to the first connecting rod 7 is further away from the first pressing plate 9. In use, the piston 51 of the pressing cylinder 5 moves downwards, causing the second pressing plate 10 to move from top to bottom closer to the first pressing plate 9. The side of the second pressing plate 10 corresponding to the second connecting rod 8 is pressed onto the first pressing plate 9 first, thus ensuring that one side of the upper housing 1 and the lower housing 2 is first pressed and fixed. See the following for details. Figure 6 As shown, during the further downward movement of piston 51, elastic element 6 continues to compress, causing the second pressing plate 10 to gradually transition to a horizontal state. Ultimately, the other side of the second pressing plate 10 is pressed onto the first pressing plate 9, completing the pressing of the other side of the upper housing 1 and the lower housing 2. This segmented pressing method allows one side of the upper housing 1 and lower housing 2 to be initially fixed before the other side is pressed and fixed. This relatively disperses the force, effectively reducing the overall deformation of the housing and internal stress concentration, thus significantly reducing the pressure on the housing, making it less prone to damage, and significantly lowering the product's damage rate.

[0037] For example, please refer to Figure 2 and Figure 3 The elastic element 6 can be a spring. Both the first connecting rod 7 and the second connecting rod 8 can be hinged to the second pressing plate 10.

[0038] In practical applications, please refer to Figure 1 The column 4 can be equipped with a pneumatic triplet 18, namely a pressure regulating valve, a filter and an oil sludge remover, so as to process and control the external compressed air through the pneumatic triplet 18.

[0039] In one specific embodiment, please refer again to Figure 2 and Figure 3It may also include a connecting block 11 and a limiting member 12. The lower end of the piston 51 is embedded in the connecting block 11 to connect the first connecting rod 7 and the elastic member 6 respectively through the connecting block 11. The upper part of the second connecting rod 8 is embedded in the bottom of the connecting block 11 and connected to the elastic member 6. A vertical limiting hole 81 is provided on the side wall of the upper part of the second connecting rod 8. The limiting member 12 is disposed in the connecting block 11 and passes through the limiting hole 81 to limit the extension and retraction stroke of the elastic member 6.

[0040] Understandably, initially, the elastic element 6 will push the second connecting rod 8 away from the piston 51 based on its own elasticity until the limiting element 12 abuts against the upper wall of the limiting hole 81. Through the cooperation of the limiting hole 81 and the limiting element 12, the maximum extension of the elastic element 6 can be limited, thereby setting the tilt angle of the second pressing plate 10 to a preset value. When the second pressing plate 10 is fully pressed onto the first pressing plate 9, the elastic element 6 contracts and causes the limiting element 12 to abut against the lower wall of the limiting hole 81. Through the cooperation of the limiting hole 81 and the limiting element 12, the maximum contraction of the elastic element 6 can be limited, preventing the elastic element 6 from further contracting after the second pressing plate 10 is fully attached to the first pressing plate 9, thus affecting the pressing stability between the second pressing plate 10 and the first pressing plate 9.

[0041] In this embodiment, preferably, the upper part of the first connecting rod 7 is also embedded in the bottom of the connecting block 11, and the side wall of the upper part of the first connecting rod 7 is threadedly connected to the inner wall of the connecting block 11.

[0042] For example, the limiting member 12 can be Figure 6 The screw shown is inserted into the interior of the connecting block 11 through the side wall of the connecting block 11.

[0043] In one specific embodiment, please refer to Figure 4 A vertical track 41 is provided on the column 4, and a connecting plate 13 is movably mounted on the vertical track 41. The pressing cylinder 5 is fixedly connected to the connecting plate 13. A buffer device 14 is provided on the top of the column 4. The buffer device 14 is connected to the connecting plate 13 and is used to drive the connecting plate 13 to move vertically.

[0044] In use, during the process of piston 51 driving the second pressing plate 10 to press against the first pressing plate 9, the connecting plate 13 can be driven to move slightly upward by the buffer device 14, thereby causing the connecting plate 13 to drive the pressing cylinder 5 to move slightly upward. This can reduce the pressing pressure between the second pressing plate 10 and the first pressing plate 9, and further reduce the pressure on the upper housing 1 and the lower housing 2.

[0045] For example, the buffer device 14 may include a buffer cylinder with a piston extending downward and connected to the top of the connecting plate 13.

[0046] In one specific embodiment, please refer to Figure 5 The bottom of the second pressing plate 10 is provided with a first fixing groove 101 adapted to the shape of the upper shell 1, and a fixing member is provided on the second pressing plate 10. The fixing member is used to fix the upper shell 1 in the first fixing groove 101.

[0047] Specifically, the upper housing 1 is disposed at the bottom of the second pressing plate 10 by being embedded in the first fixing groove 101 and is fixed by the action of the fixing member. When the piston 51 drives the second pressing plate 10 to press against the first pressing plate 9, the upper housing 1 located at the bottom of the second pressing plate 10 and the lower housing 2 located at the top of the first pressing plate 9 are pressed together to form a complete housing.

[0048] For example, the fastener may include a vacuum valve 15 disposed on the top of the second pressing plate 10. The top of the second pressing plate 10 has a through hole 102 communicating with the first fixing groove 101. One end of the vacuum valve 15 is connected to the through hole 102, and the other end is connected to an external vacuum pump. Under the action of the external vacuum pump, a negative pressure is formed in the pipe between the vacuum valve 15 and the vacuum pump, thereby adsorbing and fixing the upper housing 1 into the first fixing groove 101 through the through hole 102.

[0049] Optionally, the number of vacuum valves 15 and through holes 102 can be one or more. For example, the number of vacuum valves 15 and through holes 102 is two.

[0050] In one specific embodiment, please refer to Figure 1 The top of the first pressing plate 9 has a second fixing groove 91 adapted to the shape of the lower housing 2. The second fixing groove 91 is used to support and fix the lower housing 2. The lower housing 2 is embedded in the second fixing groove 91, thereby corresponding to the upper housing 1 located in the first fixing groove 101.

[0051] In one specific embodiment, a surrounding plate 16 is also included, which is disposed around the side wall of the pressing cylinder 5. Exemplarily, the surrounding plate 16 can partially surround the side wall of the pressing cylinder 5, and the surrounding plate 16 can be made of transparent structure, which not only provides protection but also improves the aesthetics of the equipment and facilitates observation of the pressing cylinder 5.

[0052] In one specific embodiment, please refer to Figure 1 The base 3 is also equipped with an operating table 17, which has an operating lever 171 and a regulating valve (not shown in the figure). The operating lever 171 is connected to the regulating valve, and the regulating valve is connected to the pressing cylinder 5. In use, the operator can adjust the regulating valve through the operating lever 171, thereby controlling the start and stop of the pressing cylinder 5, the piston 51 pressure, etc.

[0053] It should be noted that the operating lever 171 can also be replaced with other types of operating components, and this utility model does not specifically limit this.

[0054] In embodiments where the buffer device 14 includes a buffer cylinder, the control panel 17 may further be provided with operating components for controlling the buffer cylinder. In some cases, the operating components and regulating valve may also be located on the side wall of the column 4.

[0055] In one specific embodiment, anti-slip pads 31 are provided at each of the four corners of the bottom of the base 3. The anti-slip pads 31 improve the stability of the device during use. Optionally, the anti-slip pads 31 include, but are not limited to, rubber pads, silicone pads, etc.

[0056] In summary, the shell pressing device provided by this utility model is based on a piston connected to a second connecting rod via an elastic element. The stroke of the piston connecting to the second pressing plate via the second connecting rod is longer than the stroke connecting the piston to the second pressing plate via the first connecting rod. This causes the second pressing plate to tilt relative to the first pressing plate, thereby achieving segmented pressing between the upper and lower shells during the pressing process. This segmented pressing method effectively reduces the overall deformation of the shell and internal stress concentration, effectively reducing the pressure on the shell, making the shell less prone to damage, and significantly lowering the product damage rate.
