先前技術為著固定工件,例如元件或產品,通常利用多個氣缸,設置於工件的周圍。利用氣壓(或液壓)驅動多個氣缸以夾持工件。然而,此種方式的多個氣缸不容易同時達到夾緊位置,換句話說,由於利用多個氣壓(或液壓)機構,同時定位的精準度不佳。此外,上述機構的成本也高。In the prior art, in order to fix a workpiece, such as a component or a product, a plurality of air cylinders are usually used, which are arranged around the workpiece. Use pneumatic (or hydraulic) to drive multiple cylinders to clamp the workpiece. However, it is not easy for the multiple cylinders to reach the clamping position at the same time. In other words, due to the use of multiple pneumatic (or hydraulic) mechanisms, the simultaneous positioning accuracy is not good. In addition, the cost of the above-mentioned mechanism is also high.
故,如何通過結構設計的改良,來改良定位治具的定位效果,來克服上述的缺陷,已成為該項技術領域所欲解決的一項課題。Therefore, how to improve the positioning effect of the positioning jig by improving the structural design to overcome the above-mentioned defects has become a subject to be solved in this technical field.

The retaining block has at least one side baffle, which defines an inner space. The plurality of pushing components are disposed on the holding block, each of the pushing components includes a movable rod and an elastic element, and the movable rod moves in an actuating direction in a direction away from or toward the inner space Between the state and an original state, one end of each movable rod has a pushed portion and the other end has a pushing portion, and the elastic element is sleeved on the movable rod. The driving member reciprocates in a direction perpendicular to the moving direction of each of the movable rods to push or move away from the pushed portion of each of the movable rods.
當所述驅動件推動所述受推部時,多個所述活動桿件的所述推抵部同時以遠離所述內部空間的方向頂撐所述工件,而達到所述作動狀態。When the driving member pushes the pushed portion, the pushing portions of the plurality of movable rods simultaneously support the workpiece in a direction away from the inner space to achieve the actuation state.
當所述驅動件遠離所述受推部時,所述彈性元件提供彈力給所述活動桿件,使得所述活動桿件由所述作動狀態回復到所述原始狀態。When the driving member is away from the pushed portion, the elastic element provides elastic force to the movable rod, so that the movable rod returns to the original state from the actuated state.
