DETAILED DESCRIPTION

[0024] The technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment, and apparently, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0025] Referring to Figures 1-10 A synchronous indexing chuck, comprising a chuck seat 1, a ninety-degree clamp seat 3 and a forty-five-degree clamp seat 4 are symmetrically and slidably arranged on the chuck seat 1, a plurality of variable-angle indexing shafts 5 are rotatably arranged on the ninety-degree clamp seat 3 and the forty-five-degree clamp seat 4, limit sliding blocks 10 are arranged on the bottom of the side wall of the opposite side of the ninety-degree clamp seat 3 and the forty-five-degree clamp seat 4, a pull plate seat 6 is movably arranged on the middle of the chuck seat 1, limit grooves 61 are symmetrically arranged on the pull plate seat 6, the limit grooves 61 are at a certain angle of inclination, the limit sliding blocks 10 on both sides are slidably arranged at the limit grooves 61, and the pull plate seat 6 can realize synchronous pulling of the clamp seats on both sides through up-and-down movement.

[0026] In addition, a moving groove 11 is arranged on the upper surface of the chuck seat 1, the ninety-degree clamp seat 3 and the forty-five-degree clamp seat 4 are arranged to move horizontally in the moving groove 11, a movable opening 12 is arranged in the middle of the chuck seat 1, and a cover plate 2 is arranged on the upper surface of the chuck seat 1, so that the ninety-degree clamp seat 3 and the forty-five-degree clamp seat 4 can only move horizontally under the action of the cover plate 2 and the moving groove 11.

[0027] Meanwhile, the variable-angle indexing shaft 5 comprises a pushing groove 51 arranged on the shaft body, and a clamp groove 52 is arranged on one side surface of the variable-angle indexing shaft 5, so that the clamp groove 52 of different angles can be arranged to realize more angle machining of the workpiece.

[0028] In addition, a piston body 7, a clamp oil cylinder 8 and an oil delivery seat 9 are sequentially arranged on the bottom of the pull plate seat 6, and the pull plate seat 6 realizes hydraulic lifting movement through the piston body 7, the clamp oil cylinder 8 and the oil delivery seat 9.

[0029] In this embodiment, when clamping the workpiece, the angle of the clamp groove 52 can be customized according to the customer's requirements, so that the part itself can be inclined at a certain angle between the two variable-angle indexing shafts 5, and the secondary angle is more accurate, so that the angle of machining is more variable.

[0030] Moreover, the ninety-degree indexing piston groove 31 and the forty-five-degree indexing piston groove 41 arranged on the ninety-degree clamp seat 3 and the forty-five-degree clamp seat 4 are used to place the indexing piston groove to push the pushing groove 51, so that the variable-angle indexing shaft 5 can rotate at different angles, and these are all prior art, which are necessary structures of the indexing chuck and are well known to those skilled in the art, so their structure and function do not need to be described in detail.
