[0024] See also Figures 1 to 4 , a quick-change clamp mechanism having:

[0025] The clamping frame 1 comprises a long-side movable frame 2, mounted on the long side of the clamping frame 1; a wide-side movable frame 3, mounted on the wide side of the clamping frame 1; a clamp 4, slidably mounted on the long-side movable frame 2 and the wide-side movable frame 3; and a positioning device mounted on the clamp 4, which can secure the clamp 4 to the long-side movable frame 2 and / or the wide-side movable frame 3. The clamp 4 can be repositioned by sliding on the long-side movable frame 2 and the wide-side movable frame 3. The positioning device secures the clamp 4 to the long-side movable frame 2 and / or the wide-side movable frame 3. This allows for quick and easy disassembly, installation, and repositioning of the clamp 4.

[0026] The positioning device includes a knob plunger 6, which is threadedly connected to the clamp 4. The long-side movable frame 2 and the wide-side movable frame 3 are provided with a series of positioning holes, into which the knob plunger 6 fits. The sliding of the guide bar 5 and the quick fixation of the knob plunger 6 enable the clamp 4 to be quickly disassembled, installed, and moved, making operation simple and quick.

[0027] The clamp 4 includes a mounting base 41, to which a knob plunger 6 is threadedly connected. The mounting base 41 is also rotatably provided with an upper clamping shaft 42 and a lower clamping shaft 43, to which an upper clamping block 44 and a lower clamping block 45 are fixed, respectively. A drive mechanism is also provided to rotate the upper clamping shaft 42 and the lower clamping shaft 43. The upper clamping shaft 42 and the lower clamping shaft 43 drive the upper clamping block 44 and the lower clamping block 45 to clamp or release the workpiece.

[0028] The drive mechanism is a rack and pinion mechanism, comprising meshing upper and lower gears 46 and 47. The upper gear 46 is fixedly connected to the upper clamping shaft 42, while the lower gear 47 is fixedly connected to the lower clamping shaft 43. A drive rack 48 is also provided, which drives the upper gear 46 to rotate. The drive rack 48 drives the upper gear 46, which meshes with the lower gear 47, driving the upper and lower clamping shafts 42 and 43 to rotate. The upper and lower clamping shafts 42 and 43 drive the upper and lower clamping blocks 44 and 45 to clamp or release the workpiece.

[0029] The long side moving frame 2 and the wide side moving frame 3 are both provided with guide bars 5, and the clamp 4 is provided with a slider adapted to the guide bars 5. They play a guiding role, and the movement is more stable and reliable.

[0030] The clamping frame 1 is square, and two groups of long-side movable frames 2 and wide-side movable frames 3 are respectively provided around the clamping frame 1, which are symmetrically arranged, so that the clamping is more stable and reliable.

[0031] This mechanism is a mechanism for quickly replacing the clamping device of a clamping frame type forming machine. The long-side movable frame and the short-side movable frame are respectively installed in the X direction and Y direction of the clamping frame. A guide bar is installed on the movable frame. The clamping device is fixed to the guide bar through its own card slot and can slide along the direction of the guide bar. A knob plunger is installed on the clamping device. The clamping device can be slid to the appropriate position according to the size of the product. The pin shaft at the end of the knob plunger is inserted into the pin hole on the movable frame. The corresponding number of clamping devices can also be removed or installed according to the size of the product. The knob plunger can quickly extend and retract the end pin shaft by rotating its own knob part, thereby fixing the clamping device on the movable frame.

[0032] Operation process: Operation 1: Turn the knob on the knob plunger to retract the pin at the end of the knob plunger, and the clamping device can be moved on the guide strip. After moving to the desired position, turn the knob in the opposite direction to extend the pin at the end, and the clamping device is fixed. Operation 2: Turn the knob on the knob plunger to retract the pin at the end of the knob plunger, and the clamping device can be moved on the guide strip. The clamping device moves to the end of the guide strip and can be slid out and removed from the end of the guide strip. Operation 3: Turn the knob on the knob plunger to retract the pin at the end of the knob plunger, and the clamping device can be inserted from the end of the guide strip. Slide the clamping device to the desired position, turn the knob in the opposite direction to extend the pin at the end, and the clamping device is fixed.
