Embodiment Construction

[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0014] Such as Figure 1 ~ Figure 2 Shown: including chuck body 1, coil wire 2, gear 4, copper sleeve 5, retaining ring 6, cover plate 7, pad 8, four claws 9, first slide 10, second slide 11, four A block 12, four screw 13, the third slide 14, the fourth slide 15, etc.

[0015] The gear 4 of the present invention is embedded in the rear portion of the chuck body 1, and is fastened with the coil wire 2 by screws. The coil wire 2 is fixed in the inner cavity of the chuck body 1 and connected with the gear 4 through screws. The retaining ring 6 is in interference fit with the inner hole of the gear, and is installed in the gear 4 to play a position-limiting role. The copper sleeve 5 is in interference fit with the retaining ring inner hole, is installed in the retaining ring 6, and is installed in cooperation with the machine tool spindle to prevent we...

Abstract

The invention relates to a four-claw large pipe chuck which comprises a chuck body and clamping claws. The four-claw large pipe chuck is characterized by also comprising a wire coil, a gear, the clamping claws, first sliding seats, second sliding seats, stop blocks and lead screws, wherein the wire coil is fixed in the cavity of the chuck body and is connected with the gear through screws; the four clamping claws are respectively connected with four sliding seats; the four lead screws are respectively arranged in the four sliding seats and are located by the stop blocks; the four clamping claws are respectively engaged with the threads on the four lead screws through bottom threads and are respectively installed above the four sliding seats; and the four sliding seats are respectively engaged with the wire coil in a thread mode. The rotation of the gear can drive the wire coil to rotate, the plane motion of the entire sliding seats is realized, and self-centering clamping is completed. The self-centering clamping is completed by controlling the rotation of the gear, and single-action clamping can also be completed by individually operating the lead screws. The clamping means of the chuck is greatly enriched, processing technic is simplified, and labor intensity is reduced.

Description

technical field [0001] The invention relates to a four-jaw large-scale pipe chuck, in particular to a tool for processing large-scale pipe parts. Background technique [0002] Large-scale pipe workpieces sometimes need self-centering clamping and automatic centering to simplify processing during processing; sometimes four-jaw single-action clamping is required to increase the bearing capacity of the fixture. The existing pipe chuck lacks effective multiple composite clamping means to simplify the clamping method, and when processing large pipe parts, the chuck has a single clamping means, a small clamping range, manual operation is required, and the processing efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a four-jaw large-scale pipe chuck, which can be automatically clamped by electronic control after meshing with the corresponding ring gear on the machine tool spindle, w...
