本發明涉及一種定位治具，特別是指一種定位治具，如同機械手臂，可用以固持一工件，進而移動工件至一需要的位置。The present invention relates to a positioning jig, in particular to a positioning jig, which, like a mechanical arm, can be used to hold a workpiece and then move the workpiece to a desired position.

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.

為了解決上述的技術問題，本發明所採用的其中一技術方案是，提供一種定位治具，用以固持一工件，所述定位治具包括一固持擋件、多個推抵組件及一驅動件。所述固持擋件具有至少一側擋板，其定義出一內部空間。所述多個推抵組件設置於所述固持擋件，每一所述推抵組件包含一活動桿件及一彈性元件，所述活動桿件以遠離或朝向該內部空間的方向活動於一作動狀態以及一原始狀態之間，每一所述活動桿件的一端具有一受推部及另一端具有一推抵部，所述彈性元件套設於所述活動桿件。所述驅動件以垂直於每一所述活動桿件的活動方向往復移動以推動或遠離每一所述活動桿件的所述受推部。In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a positioning fixture for holding a workpiece, the positioning fixture includes a holding stopper, a plurality of pushing components and a driving component . 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.

In this state, the elastic element 30 is compressed to accumulate an elastic force. The shock-absorbing element 32 is slightly stretched.

如圖2、圖3所示，當驅動件40遠離受推部11時，彈性元件30提供彈力給所述活動桿件10以回復到原始狀態。活動桿件10回復的過程，所述避震元件32，可以提供受推部11緩衝的力量。As shown in FIGS. 2 and 3 , when the driving member 40 is away from the pushed portion 11 , the elastic element 30 provides elastic force to the movable rod 10 to return to the original state. During the recovery process of the movable rod 10 , the shock absorber element 32 can provide the buffer force of the pushed portion 11 .

本實施例也可以設計成具有定位後自動停止的功能，活動桿件10在抵接到工件W後，能自動停止。其中每一推抵部12(或者可稱為壓塊)可以設有一接觸感測器122，以偵測是否抵接工件W。接觸感測器122可以是位於推抵部12的外面，並內嵌於推抵部12內，朝向工件W。當推抵部12抵接工件W時，接觸感測器122提供一接觸訊號給動力元件50，以適當地停止驅動件40。接觸感測器122可以是以光線式感應、或機械式感應。例如可以是微動開關，藉由碰觸到工件W，通過電線以停止驅動件40，或者是無線的感測器，以無線方式提供訊號以控制所述驅動件40。This embodiment can also be designed to have the function of automatic stop after positioning, and the movable rod 10 can stop automatically after contacting the workpiece W. Each of the pushing portions 12 (or can be referred to as pressing blocks) may be provided with a contact sensor 122 to detect whether it abuts against the workpiece W. As shown in FIG. The contact sensor 122 may be located outside the pushing portion 12 and embedded in the pushing portion 12 , facing the workpiece W. When the pushing portion 12 abuts against the workpiece W, the contact sensor 122 provides a contact signal to the power element 50 to properly stop the driving element 40 . The touch sensor 122 can be a light sensor or a mechanical sensor. For example, it can be a micro switch that stops the driving member 40 by touching the workpiece W through a wire, or a wireless sensor that provides a signal wirelessly to control the driving member 40 .

Thereby, it is reduced to only one power source, which can not only drive multiple thrust components at the same time, improve the positioning accuracy, but also save costs. In addition, the driving member 40 is perpendicular to the moving direction of each of the movable rod members 10 , thereby saving the configuration space of the whole mechanism. In other words, the driving element 40 and the power element 50 can be disposed below the pushing elements 1 , and do not need to be disposed between the pushing elements 1 .
