一种自动夹具
摘要：
本发明公开了一种自动夹具，包括固定座(2)，固定座(2)一端固定设置气缸(1)，另一端固定设置夹具座(7)，气缸(1)的缸杆前端固定设置拉帽(3)，拉帽(3)内设置撞块(15)，夹具座(7)内设置活塞块(14)，通过第二圆柱销(13)将活塞块(14)、两个水平连杆(11)的一端和拉杆(4)铰连在一起，气缸(1)的缸体上固定设置传感器(16)，传感器(16)和气缸(1)连接PLC控制器，传感器(16)监测气缸(1)缸杆缩回或伸出是否到位，当到位后其将信号传给PLC控制器，PLC控制器控制气缸(1)工作。采用气动方式进行夹持，夹持可靠；通过传感器和PLC控制器，实现其自动夹件。
摘要（英）：

The invention discloses an automatic clamp which comprises a fixing base (2). An air cylinder (1) is fixedly arranged at one end of the fixing base (2), and a clamp base (7) is fixedly arranged at the other end of the fixing base (2). A blind nut (3) is fixedly arranged at the front end of a cylinder rod of the air cylinder (1). A collision block (15) is arranged in the blind nut (3). A piston block (14) is arranged in the clamp base (7). The piston block (14), the ends of two horizontal connecting rods (11) and a pull rod (4) are hinged together through second cylinder pins (13). A sensor (16) is fixedly arranged on a cylinder body of the air cylinder (1). The sensor (16) and the air cylinder (1) are connected with a PLC. The sensor (16) monitors whether retracting or stretching of the cylinder rod of the air cylinder (1) is in place or not, after retracting or stretching is in place, signals are transmitted to the PLC, and the PLC controls the air cylinder (1) to work. According to the automatic clamp, a pneumatic manner is adopted for carrying out clamping, and clamping is reliable. By means of the sensor and the PLC, the automatic clamp clamps parts automatically.
