[0013] 1. Compared with traditional quick positioning fixtures for double-sided foam processing, most of them use plywood to clamp and fix the foam board. The clamping structure is relatively simple, the stability of the clamped foam board is often poor, and it takes a certain amount of time to locate the clamping position of the foam board. Through the partitioned clamping and fixing method, one side of the foam board is initially fixed first, and then the other two sides are further clamped and fixed, which saves the time required to locate the position of the foam board. In addition, the foam board can be clamped and fixed according to its actual size, thereby enhancing the practical value of the device.

[0014] 2. When placing the foam board body, a first support rod is fixed by setting up a workbench, and the first support rod is used to support and fix the first supporting plate. One side of the foam board body is supported by the first supporting plate, and the first fixing frame is used to fix the first electric telescopic rod. The first electric telescopic rod is extended and retracted to adjust the height of the first pressing plate. The first pressing plate is used to press and fix the upper surface of one side of the foam board body, so as to solve the problem that most rapid positioning fixtures for double-sided foam processing have a relatively simple clamping structure and often have poor stability in clamping the foam board, thereby enhancing the flexibility of the device;

[0015] 3. Use the motor to drive the two-way adjustment screw in the through slot to rotate, rotate the two-way adjustment screw to adjust the distance between the two sets of second support rods, use the second support rods to support and fix the second support plate, and use the second support plate to support the other two sides of the foam board body, so that the two sets of second fixing frames clamp the two sides of the foam board body, thereby clamping and fixing the foam board body according to its actual size.
