Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the internal rotation type quick-change chuck for a drill rod in the present embodiment includes a housing 1 and a hollow connecting shaft 7, the connecting shaft 7 is transversely disposed in an inner cavity of the housing 1, and an annular gap is formed between an outer wall of the connecting shaft 7 and an inner wall of the housing 1. 1 one end of shell is equipped with front end housing 3, and both pass through bolt fixed connection, and 3 upper covers of front end housing close deflector 13, and deflector 13 passes through hexagon head bolt 12 and 3 fixed connection of front end housing, and front end housing 3 and drilling rod extend the connecting axle 7 inner chamber are worn to establish to drilling rod one end. The connecting shaft 7 is connected with the shell 1 through the tapered roller bearings 2, and the tapered roller bearings 2 are sleeved at two ends of the connecting shaft 7, so that the connecting shaft 7 can rotate in the inner cavity of the shell 1. Two ends of the connecting shaft 1 are respectively provided with a bearing retainer ring 11 which has a limiting effect on the tapered roller bearing 2. A plurality of jaw grooves are uniformly formed in the circumferential direction of the connecting shaft 7 at intervals, and jaws 6 are arranged in the jaw grooves, so that the jaws 6 extend into the inner cavity of the connecting shaft 7. Still be equipped with conical piston 4 in the circumferential clearance, be equipped with guide block 5 between conical piston 4 and the jack catch 6 respectively, 5 top surfaces of guide block are the inclined plane for guide block 5 is the wedge structure spare, and a plurality of 5 inclined planes of guide block contact respectively of conical surface of conical piston 4, and guide block 5 passes through hexagon socket head cap screw 10 fixed connection with jack catch 6 that corresponds. An oil inlet and an oil return port are formed in the shell 1, hydraulic oil flows into the annular gap through the oil inlet to push the conical piston 4 to move in the inner cavity of the shell 1, and the movement of the conical piston 4 drives the plurality of guide blocks 5 to synchronously and relatively approach to each other, so that the plurality of clamping jaws 6 clamp the drill rod, and the drill rod is fixedly connected with the connecting shaft 7; or the guide blocks 5 are synchronously and relatively far away, so that the clamping jaws 6 loosen the drill rod, the drill rod is separated from the connecting shaft 7, and the drill rod is conveniently moved out of the connecting shaft 7.
