Abstract
An element changer includes a plurality of operation pin members (4) inserted in a housing (3). Each of the operation pin members (4) has a wedge surface (12c). When the operation pin members (4) are pushed into the housing (3), each wedge surface (12c) is disengaged from an engaging portion (10a) provided at a leading end portion of a tubular wall portion (10) of a tool plate (2) or of a connection plate (1). This allows a tool (5) functioning as a second element to be detached from a robot arm (8) functioning as a first element.
Claims8
An element changer comprising:
- a first plate (1) configured to be attached to a first element (8);
- a second plate (2) configured to be attached to a second element (5), the second plate (2) including a tubular wall portion (10) extending from an outer peripheral edge portion of the second plate (2) in its axial direction;
- a housing (3) configured to be attached to the first element (8) via the first plate (1), the housing (3) having a diameter smaller than that of the second plate (2);
- a plurality of operation pin members (4) inserted in the housing (3), each of the pin members (4) having a wedge surface (12c) on a side close to the first plate (1);
- and
- a biasing means (13) provided in the housing (3), the biasing means (13) being configured to bias the operation pin members (4) outward in a radial direction of the housing (3),
- wherein:
- an engaging portion (10a) is provided at a leading end portion of the tubular wall portion (10) in its axial direction, the engaging portion (10a) protruding inward in a radial direction of the tubular wall portion (10);
- in a side surface of the tubular wall portion (10), a U-shaped notch (10b) is formed;
- the operation pin members (4) protrude from the housing (3) outward in a radial direction of the housing (3) beyond the notch (10b);
- and
- when the operation pin members (4) are pushed into the housing (3) against a biasing force of the biasing means (13), each wedge surface (12c) is disengaged from the engaging portion (10a), to allow the second element (5) to be detached from the first element (8).
