[0010] Figure 2 It is a side view of the utility model. DETAILED DESCRIPTION

[0011] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0012] Reference Figure 1 , this specific embodiment adopts the following technical scheme: a simple assembly and disassembly fixture for manual crimping, including a base plate 1, a workpiece support tray 2, an upper support 4, a linear auxiliary guide 5, an angle handle 6, a connecting shaft 7, a toggle clamp fixing block 8, a tension spring 9, a cam bearing follower 10 and a toggle clamp 11. The base plate 1 is provided with a workpiece support tray 2 and an upper support 4, a workpiece 3 is placed on the workpiece support tray 2, the angle handle 6 is arranged on the outer side of the workpiece support tray 2, a linear auxiliary guide 5 is arranged on the side of the upper support 4 close to the workpiece, a toggle clamp 11 is arranged on the top of the upper support 4 through the toggle clamp fixing block 8, the toggle clamp 11 is connected to the connecting shaft 7 through the cam bearing follower 10, the connecting shaft 7 is connected to the workpiece pressing block 12, the workpiece pressing block 12 is slidably matched with the linear auxiliary guide 5 through a slide rod 13, and the slide rod 13 is also connected to the toggle clamp 11 through a tension spring 9.

[0013] It is worth noting that the lower end of the tension spring 9 matches with the middle of the connecting shaft 7 and the linear auxiliary guide rail 5 respectively.

[0014] The base plate of this specific embodiment is used to place all parts on it; the workpiece support tray is used to place the workpiece to be pasted with a thin sheet; the workpiece 3 is an aluminum box with a size of W90×D180×H16[mm]; the upper support 4 is used to support the upper pressing assembly; the linear guide pair 5 is used to guide the precise movement of the pressing assembly in the Z-axis direction. The angle handle 6 is used for the gripping part, so that the operator can easily open and close the workpiece support tray. The connecting shaft 7 is used to connect the elbow clamp and the workpiece pressure block, the elbow clamp fixing block 8 is used to fix the elbow clamp, and the tension spring 9 allows the elbow clamp to return to its original position or state after being released by an external force; the cam bearing follower 10 is used to transmit the force on the elbow clamp to the workpiece; the elbow clamp is the power source of the pressing mechanism.

[0015] The working principle of this specific implementation method is: use a toggle clamp with a cantilever opening and closing angle of 112°, a crimping stroke of 15mm, and a negative pressure of 153.2N for manual crimping, and use the center alignment of the cam bearing follower to squeeze the pressing mechanism to obtain the pressure required for crimping, and transfer it to the fitting part of the workpiece surface; the center of the crimping part is connected to the tension spring, and when the toggle clamp is released, the pressing mechanism is restored to the initial position, and then the workpiece holder is removed, and the process is completed. This mechanism can be fast and simple, and can be repeatedly cycled for patch operations.

[0016] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
