Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Examples, see fig. 1 and 2: a parallel split synchronous clamp comprises a lifting cylinder 10, a fixed seat 11, a clamp seat 12, a left die clamp 13, a right die clamp 14 and a synchronous linkage device, wherein the lifting cylinder 10 is fixed on the fixed seat 11, a cylinder rod 101 on the lifting cylinder is connected with the synchronous linkage device, and the synchronous linkage device can perform corresponding actions through the driving of the lifting cylinder 10. The fixing seat 11 is internally provided with a positioning shaft sleeve 15, and the cylinder rod 101 of the lifting cylinder 10 is positioned in the positioning shaft sleeve 15 so as to avoid the shaking phenomenon of the cylinder rod 101. The clamp seat 12 is a plate-shaped structure, one end of the clamp seat is fixed on the fixed seat 11, and the other end of the clamp seat extends out of the fixed seat 11; the part of the fixture seat 12 extending out of the fixed seat 11 is provided with a sliding guide rail 16, the bottoms of the left die fixture 13 and the right die fixture 14 are provided with sliding grooves, and the sliding grooves are in sliding fit with the sliding guide rail 16, so that the left die fixture 13 and the right die fixture 14 can slide on the fixture seat 12 under the driving of a synchronous linkage device. The left die clamp 13 and the right die clamp 14 are provided with openings 17 for the mechanical gripper to be disengaged at one time, the length of the opening 17 after the left die clamp 13 and the rear die clamp 14 are closed is larger than the length of the opened mechanical gripper, when the structure is used, the mechanical gripper can place a workpiece at a specified position, and when the left die clamp 13 and the right die clamp 14 clamp the workpiece, the mechanical gripper can release the workpiece and disengage from the opening 17. The synchronous linkage device comprises a linkage arm 20, a left die rocker arm 21, a right die rocker arm 22, a pull rod 23 and a push plate 24, wherein the middle part of the side surface of the linkage arm 20 is provided with a clamping groove attached to the end surface of the cylinder rod 101, the clamping groove is fixed through a fixing bolt after being attached to the cylinder rod 101, so that the linkage arm 20 is fixedly connected with the cylinder rod 101, and can move up and down under the driving of the cylinder rod 101; two ends of the linkage arm 20 are respectively hinged with the left die rocker arm 21 and the right die rocker arm 22 and drive the left die rocker arm and the right die rocker arm to synchronously move, the other end of the left die rocker arm 21 is hinged with the push plate 24, one end of the pull rod 23 is connected with the left die clamp 13, the other end of the pull rod is fixedly connected with the push plate 24, and the right die rocker arm 22 is hinged with the right die clamp 14.
