Abstract

The invention provides an intermittent clamping device for steel plates, and belongs to the technical field of machining. The intermittent clamping device comprises a left clamping jaw, a right clamping jaw, a pull rod, a roller and a hydraulic driving system; the left clamping jaw is vertically fixed at the left end of a supporting frame; the lower end of the right clamping jaw is arranged at the right end of the supporting frame in a swinging mode through a clamping jaw pin shaft, and an inclined plane section and a semicircular groove are arranged on the right side of the right clamping jaw; the left end of the pull rod is hinged to the left clamping jaw through a pull rod pin shaft, a connecting support lug of a clamping air cylinder is hinged to the right end of the pull rod, and the roller is rotatably arranged on the pull rod through a roller supporting shaft; two ports of a hydraulic lock of the hydraulic driving system are connected with a first valve port and a second valve port respectively, and the other two ports of the hydraulic lock are connected with an upper valve port and a lower valve port respectively; and a third valve port of a three-position four-way reversing valve is connected with an oil tank, and a fourth valve port of the three-position four-way reversing valve is connected with one end of an oil pump and one end of an overflow valve. According to the intermittent clamping device, the steel plates are clamped intermittently, the structure is reasonable, and the stability is good.
本发明提供一种钢板间歇性夹紧装置,属于机械加工技术领域。它包括左夹爪、右夹爪、拉杆、滚轮、液压驱动系统,左夹爪竖直固定在支承机架的左端,右夹爪的下端通过夹爪销轴可摆动设置在支承机架的右端,右夹爪的右侧设置有斜面段和半圆槽,拉杆的左端通过拉杆销轴铰接在左夹爪上,夹紧气缸的连接支耳和拉杆的右端铰接,滚轮通过滚轮支轴可转动设置在拉杆上,液压驱动系统的液压锁的两个端口分别连接第一阀口和第二阀口,液压锁的另外两个端口分别连接上阀口和下阀口,三位四通换向阀的第三阀口连接油箱,三位四通换向阀的第四阀口连接油泵的一端和溢流阀的一端。本发明实现对钢板间歇性的夹紧,结构合理,稳定性好。
