Specific embodiment

In the description of the utility model, it is to be understood that " " center ", " on " in term, " under ", "front", "rear", The orientation or position relationship of the instructions such as "left", "right" are based on orientation shown in the drawings or position relationship, are for only for ease of and retouch State the utility model and simplify description rather than instruction or imply signified device or component must have specific orientation, with Specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.In addition, term " first ", " second " Description purpose is only used for, and it is not intended that instruction or hint relative importance.

, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the utility model Dress ", " connection ", " connected " should be interpreted broadly, for example, it may be being fixedly connected or dismantling connection or integrally connecting It connects；Can be mechanical connection or electrical connection；It can be directly connected or be indirectly connected by intermediary, It can be the connection of two component internals.For the ordinary skill in the art, can above-mentioned art be understood with concrete condition Language is in the concrete meaning of the utility model.

Fig. 1 to Fig. 3 is referred to, Fig. 1 to Fig. 3 revealed is a kind of quick rotation fixture of robot, including clamp bottom board 1st, block 2 and fixture upper plate 3 in fixture, block 2 is located on clamp bottom board 1 in the fixture, and the fixture upper plate 3 is located at block in fixture On 2, sealing ring 4 is equipped between block 2 in the fixture upper plate 3 and fixture；It is equipped at the middle part of the fixture upper plate 3 for other The hole 31 of interfacing part insertion, the piston guide cylinder 32 equal with the internal diameter in hole 31 is set along the axial direction in hole 31, in the work It fills in and is arranged with piston 33 on the outer wall of guide cylinder 32, spring 34 is equipped between piston 33 and fixture upper plate 3；It is led in the piston More than two steel ball holes 36 stretched out for 35 part of steel ball are equipped with to the circumference of cylinder 32, steel is equipped in the steel ball hole 36 Pearl 35；Semicircular recess 37 is equipped on the wall surface compared with the piston guide cylinder 32 of the piston 33；In the fixture Block 2 is equipped with the air flue 21 of driving piston 33.
