Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0015] Such as figure 1 and figure 2 Shown: in order to ensure machining accuracy, high machining efficiency, and meet the processing needs of large-scale tubes, discs, and rods, the present invention includes a disc body 1, and a central part of the disc body 1 is provided with a The large through hole 8 is provided with a plurality of uniformly distributed claws 4 on the outer ring of the large through hole 8; a claw movement drive mechanism for driving the claws 4 to move synchronously is arranged in the disc body 1 .

[0016] Specifically, the large through hole 8 on the disc body 1 can meet the processing requirements of pipes. The claws 4 are located above the disc body 1 and evenly distributed on the outer ring of the large through hole 8. The inner diameter of the large through hole 8 can be 620 mm. The claw motion drive mechanism can drive the synch...

Abstract

The invention relates to a clamp, in particular to a large-hole diameter multifunctional precise multi-claw synchronous clamp, specifically relates to a tool for processing large-sized pipe, plate and rod-class parts, and belongs to the technical field of tool clamps. According to the technical scheme provided by the invention, the large-hole diameter multifunctional precise multi-claw synchronous clamp comprises a plate body; a large through hole communicated with the plate body is formed in the central area of the plate body; the outer ring of the large through hole is provided with clamping jaws distributed evenly; a clamping jaw motion driving mechanism used for driving the clamping jaws to synchronously move is arranged in the plate body. According to the large-hole diameter multifunctional precise multi-claw synchronous clamp disclosed by the invention, the machining precision can be ensured, and the machining efficiency is high; self-centering clamping is finished by controlling gear rotation, so that the machining process is simplified, and the labor strength is reduced; the machining requirements of the large-sized pipe, plate and rod-class parts can be met.

Description

technical field [0001] The invention relates to a fixture, in particular to a large-aperture multi-function precision multi-jaw synchronous fixture, specifically a tooling used for processing large tubes, disks and rods, belonging to the technical field of tooling fixtures. Background technique [0002] Large-scale tubes, disks, rods and thin-walled easily deformable workpieces need to be clamped synchronously with multiple jaws during processing, and the center is automatically centered to simplify processing and ensure high-precision processing. 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. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a large-aperture multi-functional precision multi-ja...
