SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a not enough to prior art exists, the utility model aims at providing a two vice that open of synchronous pneumatics to what solve current two vice adoption that open in step is hydraulic pressure or atmospheric pressure as power, hydraulic pressure piece or atmospheric pressure piece production effort under keeping silent two for two keep silent carry out synchronous movement, hydraulic pressure or atmospheric pressure receive ambient temperature's influence easily, expand or atrophy, lead to opening the problem that vice clamping work caused the influence to two.

In order to achieve the above purpose, the present invention is realized by the following technical solution: a synchronous pneumatic double-open vice structurally comprises a cylinder, a vice bench and a clamping plate, wherein the cylinder is arranged in the middle of the positive end face of the vice bench, the two clamping plates are arranged at the upper end of the vice bench and connected in a sliding way, one end of the cylinder close to the clamping plate is provided with a piston rod embedded in the vice bench, a synchronizer is arranged in the vice bench, the synchronous device comprises a slide rail, a sliding plate, an action chute, a positioning shaft and a synchronous action frame, the slide rail is arranged at the upper end of the sliding plate and is connected with the sliding plate in a sliding way, the upper ends of the left and right parts of the synchronous action frame are respectively connected with the action chutes at the lower ends of the two sliding plates in a transmission fit manner, the synchronous action frame is arranged at the upper end of the piston rod and connected in a linkage mode, and two positioning shafts are arranged on the end face, close to the air cylinder, of the synchronous action frame.

Further, the clamping plate is fixedly arranged at the upper end of the sliding plate.

Furthermore, a positioning sleeve corresponding to the positioning shaft is arranged on the positive end face of the vice bench.

The utility model has the advantages that: adopt the synchronous relative movement device in the two vice of opening of cylinder drive to carry out the structure to the work piece clamping, the effectual drive end that prevents synchronous relative movement device receives external factors to disturb to the work of two vice clamping causes the influence.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides a technical solution of a synchronous pneumatic double-open vice: the structure of the device comprises an air cylinder 1, a vice bench 2 and two clamping plates 3, wherein the air cylinder 1 is arranged in the middle of the positive end face of the vice bench 2, the clamping plates 3 are arranged at the upper end of the vice bench 2 and are connected in a sliding manner, a piston rod embedded in the vice bench 2 is arranged at one end, close to the clamping plates 3, of the air cylinder 1, a synchronizing device is arranged in the vice bench 2 and comprises a sliding rail 201, a sliding plate 202, an acting sliding groove 203, a positioning shaft 204 and a synchronizing acting frame 205, the sliding rail 201 is arranged at the upper end of the sliding plate 202 and is connected in a sliding manner, the sliding plate 202 is provided with two synchronizing devices, the upper ends of the left part and the right part of the synchronizing acting frame 205 are respectively connected with the acting sliding grooves 203 at the lower ends of the two sliding plates 202 in a transmission fit manner, the synchronizing acting frame 205 is, the end face of the synchronization action frame 205 close to the cylinder 1 is provided with two positioning shafts 204, the clamping plate 3 is fixedly arranged at the upper end of the sliding plate 202, and the positive end face of the vice table 2 is provided with a positioning sleeve corresponding to the positioning shafts 204.
