Detailed Description

Reference numerals: 1, a hydraulic driving mechanism; 1.1 a movable block; 2, clamping blocks; 2.1 mounting a counter bore by a bolt; 3.1 a first plane; 3.2 a first cambered surface; 4.1 a second cambered surface; 4.2 a second plane; 10 a four-way valve; 10.1 plane of the end of the four-way valve; 10.2 cambered surface of the end of the four-way valve; 10.3 circular flange of four-way valve.

As shown in fig. 1 to 3, a hydraulic clamp includes a hydraulic driving mechanism 1, the hydraulic driving mechanism 1 has two movable blocks 1.1, the two movable blocks 1.1 can move towards each other or move away from each other, a clamping block 2 is fixed at each movable block 1.1, and each clamping block 2 includes a first clamping surface and a second clamping surface. The first clamping surface is closer to the movable block 1.1 than the second clamping surface. A step part is formed between the first clamping surface and the second clamping surface. The clamping block and the movable block are fixed through bolts. The first clamping surface comprises two first cambered surfaces 3.2 and a first plane 3.1 connecting the two first cambered surfaces 3.2, and the first plane 3.1 is positioned between the two first cambered surfaces 3.2. The second clamping surface comprises two second planes 4.2 and a second cambered surface 4.1 connecting the two second planes 4.2, and the second cambered surface 4.1 is positioned between the two second planes 4.2.

As shown in the figure, the movable block (or called as a clamping head) can realize the closing and opening operation under the driving of a hydraulic driving mechanism, and the clamping block is fixedly connected with the movable block. As shown in the figure, the tip of four-way valve is the rectangle of taking the fillet, and the other end department has the annular flange of circle, thereby the first plane and two first cambered surfaces of first clamping face form the centre gripping to four-way valve tip, and the second cambered surface of second clamping face just forms the centre gripping to four-way valve annular flange of circle, thereby the centre gripping atress distributes evenly, and whole centre gripping stable in structure, under hydraulic drive mechanism's drive, the centre gripping is convenient, can artifical centre gripping, also can realize the automatic feeding of manipulator.

While the utility model has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the utility model as defined in the following claims.
