Description

Technical Field

[0001] The utility model relates to the technical field of pressure-holding jigs, in particular to a multi-directional side-pushing pressure-holding jig. Background Technique

[0002] The multi-directional side-pushing pressure-holding jig is an auxiliary device for electronic product assembly. The pressure-holding jig mainly includes an upper mold and a lower mold. The upper mold is provided with a pressure head, and the lower mold is provided with a cavity. The connection mode of these components enables the pressure head to hold the pressure on the pressure-holding part located in the cavity. The material of the pressure head and the inner surface of the cavity is usually a buffer material. Such a design aims to provide a jig that can improve the pressure-holding yield. The application range of the pressure-holding jig is wide, including but not limited to fields such as electronic product assembly, circuit board testing, and various handicraft production. Its main function is to assist in controlling the position or movement, improving work efficiency and product quality.

[0020] In order to more clearly understand the above - mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification. Embodiment 1

[0022] As Figures 1-4As shown in the figure, the utility model provides a multi-directional side-pushing and pressure-holding jig, which includes a jig mechanism 1. A pressure regulating mechanism 2 is fixedly connected to the side of the jig mechanism 1. A pressure-holding lower mold 13 is installed on the upper part of the jig mechanism 1. A pressure-holding upper mold 14 is arranged above the pressure-holding lower mold 13. The pressure regulating mechanism 2 includes an adjusting frame 21 and a telescopic rod 27. The adjusting frame 21 is fixedly connected to the side of the jig table frame 11. And an adjusting bolt 22 is rotatably connected to the surface of the adjusting frame 21. A fixing frame 23 is threadedly connected to the surface of the adjusting bolt 22. One end of the fixing frame 23 is fixedly connected to a pressurizing cylinder 24. The lower end of the pressurizing cylinder 24 is fixedly connected to a connecting plate 25. A pressure head 26 is fixedly connected to the lower part of the connecting plate 25. The pressure head 26 is inserted into the pressure-holding upper mold 14. One end of the telescopic rod 27 is fixedly connected to the connecting plate 25. And the other end of the telescopic rod 27 is fixedly connected to the pressure-holding upper mold 14. A spring 28 is arranged on the surface of the telescopic rod 27. One end of the spring 28 is fixedly connected to the connecting plate 25. And the other end of the spring 28 is fixedly connected to the pressure-holding upper mold 14. A plurality of telescopic rods 27 are arranged at the bottom of the connecting plate 25. The plurality of telescopic rods 27 are evenly distributed at the bottom of the connecting plate 25.

[0023] Next, specifically describe the specific settings and functions of this embodiment. The pressurizing cylinder 24 is used to push the connecting plate 25, the pressure head 26 and the pressure-holding upper mold 14 to move downward. At this time, the surface of the pressure-holding upper mold 14 is attached to the surface of the pressure-holding lower mold 13. As the pressurizing cylinder 24 continues to push the connecting plate 25 downward, the pressure head 26 presses the workpiece. After the pressure-holding upper mold 14 is attached to the upper part of the pressure-holding lower mold 13, as the connecting plate 25 continues to move downward, the telescopic rod 27 and the spring 28 are compressed, so that the pressure of the connecting plate 25 on the pressure head 26 increases linearly, improving the stability of the pressure received by the workpiece inside the pressure-holding upper mold 14 and avoiding the sudden increase in the pressure of pressure holding, which may cause damage to the workpiece.

[0024] By rotating the adjusting bolt 22, the fixing frame 23 is driven to adjust the height. By driving the pressurizing cylinder 24 through the fixing frame 23 to adjust the height, the height of the output end of the pressurizing cylinder 24 can be adjusted. When a large pressure-holding pressure needs to be provided for the workpiece, the height of the pressurizing cylinder 24 is reduced. When the pressure of pressure holding needs to be reduced, the height of the pressurizing cylinder 24 is increased, which is convenient for adjusting the pressure-holding pressure of the workpiece. When the fixing frame 23 is adjusted for lifting. Embodiment 2

[0025] As Figures 1-4As shown in the figure, a horizontal movement component 12 is fixedly connected to the surface of the jig bench 11. The pressure-holding lower mold 13 is installed above the horizontal movement component 12. A guide rail 15 is fixedly connected to the surface of the jig bench 11. A slider 16 is slidably connected to the surface of the guide rail 15. The slider 16 is fixedly connected to the side surface of the pressure-holding upper mold 14. Two adjusting bolts 22 are arranged on the surface of the adjusting frame 21. The two adjusting bolts 22 are symmetrically distributed on the surface of the adjusting frame 21. The fixing frame 23 is slidably connected to the side surface of the adjusting frame 21.

[0026] The effect achieved by the entire embodiment is that the pressure-holding lower mold 13 is moved to the side close to the operator through the horizontal movement component 12. Subsequently, the operator places the workpiece inside the pressure-holding lower mold 13. Then, the pressure-holding lower mold 13 is moved below the pressure-holding upper mold 14 through the horizontal movement component 12. The position of the pressure-holding lower mold 13 is driven by the horizontal movement component 12 to move, facilitating the operator's feeding and discharging operations. The fixing frame 23 is limited by the adjusting frame 21 to improve the stability of the fixing frame 23 during movement. When the pressure-holding upper mold 14 moves up and down, the slider 16 slides along the guide rail 15 to limit the movement of the pressure-holding upper mold 14 and improve the stability of the movement of the pressure-holding upper mold 14.

[0027] Usage method and working principle of this device: The pressure-holding lower mold 13 is moved to the side close to the operator through the horizontal movement component 12. Subsequently, the operator places the workpiece inside the pressure-holding lower mold 13. Then, the pressure-holding lower mold 13 is moved below the pressure-holding upper mold 14 through the horizontal movement component 12;

[0028] Then, the pressure cylinder 24 is pushed to drive the connecting plate 25, the pressure head 26, and the pressure-holding upper mold 14 to move downward. At this time, the surface of the pressure-holding upper mold 14 is attached to the surface of the pressure-holding lower mold 13. As the pressure cylinder 24 continues to push the connecting plate 25 downward, the pressure head 26 presses the workpiece. After the pressure-holding upper mold 14 and the upper part of the pressure-holding lower mold 13 are attached, the telescopic rod 27 and the spring 28 are compressed as the connecting plate 25 continues to move downward;

[0029] The height of the fixing frame 23 is adjusted by rotating the adjusting bolt 22. The height of the pressure cylinder 24 is adjusted by driving the pressure cylinder 24 through the fixing frame 23. By adjusting the height of the pressure cylinder 24, the height of the output end of the pressure cylinder 24 can be adjusted. When a large pressure-holding pressure needs to be provided to the workpiece, the height of the pressure cylinder 24 is reduced. When the pressure-holding pressure needs to be reduced, the height of the pressure cylinder 24 is increased, facilitating the adjustment of the pressure-holding pressure of the workpiece. When the fixing frame 23 is adjusted up and down, the fixing frame 23 is limited by the adjusting frame 21. When the pressure-holding upper mold 14 moves up and down, the slider 16 slides along the guide rail 15 to limit the movement of the pressure-holding upper mold 14.

[0030] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
