【正文】 壓傳動(dòng)、螺紋傳動(dòng)、夾緊力、生產(chǎn)效率 Abstract Hydraulic machine to thread the jaw is jaw improvement, mainly for the into mass production. He can achieve rapid, loosen up, and can ensure the clamping force can avoid excessive clamping force and make relatively thin part deformation. In order to achieve rapid clamping and loosen, the traditional thread into hydraulic transmission, activities of the body is fixed by clamp brake handle to drive the steel with brake block through the friction will carry death activities, so as to realize the activities and clamp and the fast moving, clamp and clamping force by the clamping spring to ensure that, we can adjust the spring tension level to ensure that the size of the clamping force. Hydraulic machine with the traditional thread a jaw jaw or some disadvantages pared. One is better than the traditional in the cost to expensive, and relatively speaking, manufacturing plex, the operation is more plicated。 傳統(tǒng)的螺紋臺(tái)虎鉗工作效率較低。但單獨(dú)適合鉗工已經(jīng)足夠了。 4 工作原理 ： 臺(tái)虎鉗的夾緊力是靠彈簧來保證的，液壓系統(tǒng)的功用只是讓活動(dòng)鉗口克服彈簧的張力向左移動(dòng)一點(diǎn)距離， 其工作步驟如下： 一、通過調(diào)整調(diào)整螺母 1，調(diào)整好彈簧在圖示位置張力，使得張力等于要加工零件的夾緊力 二、壓油手柄 16，通過油管 15 給 6 柱塞缸注入液壓油，通過 6 推動(dòng) 5 活動(dòng)鉗口向左移動(dòng)。實(shí)現(xiàn)快速夾緊。 與傳統(tǒng)的螺紋臺(tái)虎鉗相比較，鉗工用臺(tái)虎鉗有以下缺點(diǎn)： 。只要把剎車手柄 8 再 往上拉，就可以拖動(dòng)活動(dòng)鉗口，實(shí)現(xiàn)快速松開。 2. 因?yàn)橐簤涸菢?biāo)準(zhǔn)件，盡量選取標(biāo)準(zhǔn)件。再由 A=π R178。便于設(shè)計(jì)，所以選擇柱塞直徑為 8mm的柱塞式液壓泵。此時(shí)作用在柱塞式液壓泵上面的力為 F=PA F=π 4 4≈ 300N 經(jīng)過杠桿，操作者用不到 300N 的力就能很輕松的操作了，所以選取 的液壓元 件合理 。此時(shí)作用在柱塞式液壓泵上面的力為 F=PA F=π 4 4≈ 300N 經(jīng)過杠桿，操作者用不到 300N 的力就能很輕松的操作了，
