摘要
液壓臺虎鉗是對現(xiàn)有螺紋傳動臺虎鉗的改進(jìn)，主要用于成批生產(chǎn)。它能實現(xiàn)快速夾緊與快速松開，且能保證夾緊力大小。這樣就可以避免過去要夾緊一個較薄的零件時，因夾緊力沒有辦法確定調(diào)式的時間，同時因能實現(xiàn)快速夾緊與快速松開，從而大大的提高生產(chǎn)效率。
為了實現(xiàn)快速夾緊與快速松開，將傳統(tǒng)的螺紋改成液壓傳動，活動鉗身的固定通過剎車手柄來帶動鋼帶剎車塊通過摩擦力來抱死活動鉗身，從而實現(xiàn)活動鉗身的快速移動，而夾緊力則由夾緊彈簧來保證.我們可以通過調(diào)整彈簧的張緊程度來保證夾緊力的大小。
液壓臺虎鉗與傳統(tǒng)的螺紋臺虎鉗相比是有不足之處的。一是在成本上要比傳統(tǒng)的臺虎鉗要貴，而且相對來說,制造復(fù)雜,操作也復(fù)雜一些;二是液壓臺虎鉗的受力方向受到限制，較大的力（如沖擊力）只能朝固定鉗身方向，給操作者帶來不便。這些不足之處是還需改進(jìn)的，以后要朝這個方向努力。
關(guān)鍵詞：液壓傳動；螺紋傳動；夾緊力
Abstract
The hydraulic bench vice is the improvement of the transmission bench vice of existing whorl , mainly used for producing by batch. It can realize clamping and unclamping fast, and can guarantee to clamp the intensity of strength. In this way it can avoid such situation that when clamping a thin part in the past, the time go to the mode cannot confirm, and can make clamping and unclamping fast at the same time , so can improve production efficiency in a high intensity.
In order to make clamping and unclamping fast, make the traditional whorl into hydraulic transmission, the fixation of the activity pincers depend on embracing activity pincers body firmly through frictional force comes by the brake handle driving steel band brake lump. That realizes the fast movement of the activity pincers body, while clamped strength guaranteed by clamping the spring. We can guarantee to clamp the intensity of strength by adjusting the tight intensity of the spring.
Compared with traditional whorl bench vice, the hydraulic bench vice has weak point. The first is more expensive than the traditional bench vice on the cost, and it is a little more complicated in manufacture and operation. The second, the strength direction of hydraulic bench vice is limited, greater strength (such as shock power ) can only be in the body direction of the fixed pincers , bring inconvenience to operator. These weak points are still should be improved, and diligent is needed in this direction later.
Key words: Hydraulic transmission; Transmission of the whorl; Clamp strength
