Detailed ways

As shown in FIG. 1 , a wedge self-locking double-station pressing fixture includes a driving device 1 and a booster lever 3 , and the driving device 1 is a linear motor. The end of the driving device 1 is provided with a booster block 2, the middle part of the booster block 2 is provided with a vertical groove 2-1, and the upper end and the middle part of the booster lever 3 are rotatably equipped with a roller 1 8 and a roller 2 9. The roller one 8 is arranged in the vertical groove one 2-1, and the cooperation between the vertical groove one 2-1 and the roller one 8 can well solve the problem of insufficient degrees of freedom of the booster lever 3 . The two rollers 9 are arranged in the vertical groove two 5-1 in the middle of the double-sided wedge 5, and the cooperation between the two vertical grooves 5-1 and the two rollers 9 can well solve the problem of insufficient degrees of freedom of the booster lever 3 . The lower end of the booster lever 3 is rotatably installed on the fulcrum 4, and the booster lever 3 has a booster function, which can significantly reduce the driving power of the driving device 1. The lower side of the double-sided wedge 5 is symmetrically provided with two matching wedge indenters 6 for pressing the workpiece 10. The double-sided wedge 5 and the wedge indenter 6 are used in conjunction with a self-locking function. The driving device 1 can be stopped working during this time, and the energy-saving effect is remarkable. The lower sides of the two wedge indenters 6 are provided with return springs 7, which can automatically lift the wedge indenters 6 positioned at non-processing positions, so as to facilitate the unloading of finished workpieces 10. the
