In the figure, two fixing seats 307 are slidably mounted on the circumferential surface of the positioning shaft 306 (through holes are provided on the two fixing seats 307, and the through holes have no internal threads. The fixing seats 307 slide on the positioning shaft 306 through the through holes. The lower end of the fixing seats 307 is a stepped chuck structure for clamping parts), and four nuts 308 are threadedly mounted on the circumferential surface of the positioning shaft 306. A nut 308 is installed on each side of each fixing seat 307, which plays a role in limiting and adjusting the position of the fixing seat 307 on the positioning shaft 306.

[0046] Working principle and use process of modular tooling:

[0047] When the modular tooling is in use, the support of the cross plate 2 can be achieved under the action of the support plate 1, thereby ensuring the stable positioning of the cross plate 2, and the installation stability of the hydraulic cylinder 301 can be ensured under the action of the cross plate 2. The support purpose of the support plate 1 can be achieved under the action of the support seat 5, and the support plate 1 and the support seat 5 can be disassembled for easy assembly and installation; after starting the hydraulic cylinder 301, the height adjustment purpose of the movable plate 302 and the components thereunder can be achieved, thereby achieving the clamping purpose of the upper ends of parts of different heights, and the movement stability of the movable plate 302 can be guaranteed with the cooperation of the limit seat 303 and the support plate 1, and by adjusting the axial position of the four nuts 308 on the positioning shaft 306, the spacing between the two fixed seats 307 can be changed, thereby achieving the clamping purpose of parts of different widths, that is, under the action of the fixing mechanism 3, the vertical and longitudinal clamping and adjustment purposes can be achieved. By changing the angles of the supporting plate 401 and the side plate 402 inside the supporting plate 1, the purpose of supporting the lower end of the part can be achieved, that is, the purpose of supporting different angles or lower inclinations can be achieved. By changing the position of the fastening nut 405 on the circumferential surface of the fixed shaft 403, the spacing between the two clamping pads 404 can be changed, that is, the purpose of clamping parts of different widths can be achieved. When the supporting plate 401 needs to be flipped to adapt to the shape of the bottom surface of the part, it is achieved by changing the angle of the side plate 402. At this time, the end of the limiting shaft 406 connected to one end of the side plate 402 will be inside the supporting plate 1. The side plate 402 is slid on an arc surface in the through hole, thereby realizing the rotation of the side plate 402 relative to the arc surface (the rotation process takes the sliding contact point between the limit shaft 406 and the arc surface as the center of the circle), and then realizing the side plate 402 driving the support plate 401 to flip. After the adjustment is completed, at least one limit nut is installed on each of the two limit shafts 406 to ensure that at least two limit nuts are installed between the side plate 402 and the support plate 1, thereby achieving the purpose of fixing the limit shaft 406, the side plate 402 and the support plate 401, and finally meeting the installation stability of the support mechanism 4, that is, the purpose of fixing the lower end of the part can be achieved. Under the action of the support mechanism 4, horizontal clamping is achieved, which is adapted to the support of the lower end of parts of different shapes, has strong practicality and good use effect.
