Clamp apparatus for industrial robot

摘要

A clamp apparatus for an industrial robot includes a base unit, a first clamp unit, and a second clamp unit. The first clamp unit includes first and second claws, first and second driving sources, and first and second linear guides. The first and second driving sources move the first and second claws to the first clamp positions. The first and second linear guides movably support the first and second claws to the base unit. The second clamp unit includes third and fourth claws, third and fourth driving sources, and third and fourth linear guides. The third and fourth driving sources move the third and fourth claws to the second clamp positions. The third and fourth linear guides movably support the third and fourth claws to the base unit.

主权项

1. A clamp apparatus, comprising:
a base unit; a first clamp unit having first and second claws facing each other in a first axial direction for clamping a work piece at a first clamp position in the first axial direction, first and second driving sources linked to the first and second claws respectively for moving the first and second claws to the first clamp position, and first and second linear guides disposed at the base unit for movably supporting the first and second claws to the base unit; and a second clamp unit having third and fourth claws facing each other in a second axial direction orthogonal to the first axial direction for clamping the work piece at second clamp positions in the second axial direction, third and fourth driving sources linked to the third and fourth claws respectively for moving the third and fourth claws to the second clamp position, and third and fourth linear guides disposed at the base unit for movably supporting the third and fourth claws to the base unit, wherein the base unit includes a plate-like member having first and second protruded pieces protruding from the plate-like member in the first axial direction and third and fourth protruded pieces protruding from the plate-like member in the second axial direction, wherein the first to fourth claws are disposed on the first to fourth protruded pieces, respectively, wherein the first to fourth driving sources are disposed on first surfaces of the first to fourth protruded pieces, respectively, wherein the first to fourth linear guides are disposed on second surfaces of the first to fourth protruded pieces, respectively, and wherein the first surfaces and the second surfaces are opposite surfaces of the first to fourth protruded pieces.
