Embodiment Construction

[0009] The present invention will be further described below in conjunction with the embodiments in the drawings:

[0010] Such as figure 1 As shown, it includes a disc body 1, a coil wire 2, a sliding seat 3, a claw 4, a gland 5, a bevel gear 6 and a pin 7.

[0011] The plate body 1 is provided with three straight grooves, three claws 4, three sliding seats 3, a coil 2, three bevel gears 6, a gland 5 and three pins 7. The three jaws 4 are respectively connected with the three sliding seats 3 through the sliding seat I-shaped groove. The bottom of the sliding seat 3 is provided with a flat thread, and the flat thread engages with the corresponding flat thread of the coil 2, and the coil 2 is inserted in the The inner cavity of the disc body 1 is fixed by the gland 5, the three bevel gears 6 are positioned and installed on the side of the disc body 1 by three pins 7 respectively, and the bevel gear 6 keeps meshing with the corresponding tooth surface on the disc wire 2. The three ...

Abstract

The invention relates to a large-specification multi-jaw precise self-centring chuck comprising a chuck body, a chuck wire, three slide seats, three clamping jaws, a gland and three bevel gears, wherein the chuck wire is inlaid in an inner cavity of the chuck body and fixed via the gland; the three clamping jaws are respectively connected with the three slide seats via I-shaped grooves of the slide seats; threads are arranged on the bottoms of the slide seats and engaged with threads on the chuck wire to form an integer; the three bevel gears are located and installed on an outer ring of the chuck body via three dowels respectively and engaged with the chuck wire; and self-centring clamping is finished by controlling the rotations of the three bevel gears. The large-specification multi-jaw precise self-centring chuck disclosed by the invention is compact and reasonable in structure, and capable of performing a self-centring clamping operation by operating the chuck wire so as to realize clamping machining for workpieces having diameters Phi being greater than 1.25M; and a through hole in the chuck body is large in diameter, and the self-centring clamping can be finished by controlling the rotations of the gears, so that the machining process is simplified, the labour intensity is alleviated, and machining demands on components such as tubes can be met.

Description

Technical field [0001] The invention relates to a large-size multi-jaw precision self-centering chuck, which is used for tooling for processing large-scale pipes, plates, and rods, and belongs to the technical field of mechanical equipment. Background technique [0002] Large-scale pipes, discs, and rods need to be self-centered and clamped during processing, and automatically centered to simplify processing and ensure processing accuracy. The existing self-centering chuck lacks effective processing range and processing accuracy, and the clamping range is small. The large-size four-jaw single-action chuck cannot guarantee the processing accuracy and the processing efficiency is low, while the large-size multi-jaw precision self-centering chuck can achieve. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings and provide a large-size multi-jaw precision self-centering chuck, which can ensure processing accuracy and high proce...
