Linked double-station center fixture

Abstract

The application discloses a linked double-station center fixture. The linked double-station center fixture comprises a power device, and a first fixture device and a second fixture device which are connected with the power device, wherein a connecting device is arranged between the power device as well as the first fixture device and the second fixture device and comprises a first vertical rod connected with the power device and a transverse rod connected with the first vertical rod, two ends of the transverse rod extend in the axial direction of the first vertical rod to the other side of thefirst vertical rod to form a second vertical rod and a third vertical rod which are mutually symmetrical, the second vertical rod is connected with the first fixture device, and the third vertical rod is connected with the second fixture device. According to the linked double-station center fixture disclosed by the application, in a unique connecting rod manner, a single air cylinder can simultaneously control a double-station center fixture; and besides, a servo electric cylinder is adopted, so that the opening angle of a center fixture mechanism can be accurately controlled, an air source is not needed, purely electric control is realized, and requirements for working conditions are reduced.

Description

technical field [0001] The present application relates to the field of fixture technology, in particular to a linkage double-station center fixture. Background technique [0002] In the prior art, in the automation industry, the double-station linkage center clamp adopts the center clamp cylinder, which is controlled by two independent center clamps, so as to realize the clamping action. Due to the use of two center clips for independent control, the requirements for the synchronous action of the two center clip cylinders are very high. The existing technology often cannot achieve complete synchronization, and the pneumatic center clip cylinder cannot control the stroke and the opening and closing angle. It can only be opened or closed at 180°. At the same time, the pneumatic components have a relatively high quality of compressed air, which will seriously affect the life of the cylinder if the air source is not good or the air pressure is insufficient.

Problems solved by technology

Due to the use of two center clips for independent control, the requirements for the synchronous action of the two center clip cylinders are very high. The existing technology often cannot achieve complete synchronization, and the pneumatic center clip cylinder cannot control the stroke and the angle of opening and closing. Can only be opened or closed at 180°

At the same time, the pneumatic components have a relatively high quality of compressed air, which will seriously affect the life of the cylinder if the air source is not good or the air pressure is insufficient.
