Description

Clipper with quick change function

Technical field

The invention relates to a spreader, in particular to a clip hanger with a quick change function.

Background technique

Generally, for the surface processing of a light weight and small workpiece, such as painting the surface of the workpiece or other similar processing procedures, a suitable gripper can be used to clamp and move the workpiece.

The Taiwanese Patent No. M402879 discloses a hanger device which is provided with a hanging clamp on a hanger base, the hanger has opposite first and second clamping portions, and the first and second clamping portions Each of the clamp arm and the touch arm has a shaft joint between the clamp arm and the touch arm, and the first and second clamp portions are rotatably shaft-mounted on the hanger base. When the hanger passes a touch device, the contact arm of the hanger is touched to open the clamp arm; after the hanger passes the device, the clamp arm of the hanger returns to the clamping position.

It should be noted that the trigger device is a front end plate and a rear slant plate formed at an opposite end of a pressing plate. The hanging clip moves from the front slanting plate into the pressing plate, the hanging is gradually opened; the hanging clip moves within the length of the pressing plate, and the hanging clip is continuously opened; the hanging clip is moved by the pressing plate The rear sloping plate and the hanging clip are gradually clamped. In other words, within the total length of the compression plate and the rear swash plate, since the hanger is not yet clamped, the workpiece cannot be separated from the hand, otherwise the workpiece will fall. Therefore, it is obviously time consuming and inconvenient for the processing program. In addition, the hanger has a joint at one end, and the joint is used for locking on the conveying device. When the hanger is to be replaced, it is necessary to loosen the solid component and re-lock the locking component, so the operation is time consuming and inconvenient.

detailed description

Referring to FIG. 1 and FIG. 2, a clip hanger includes a substrate (10) and a first clamping group (20). The first clamping group (20) is mounted on one side of the substrate (10), and the first clamping group (20) is openable for clamping a workpiece (not shown).

Further, the first clamping group (20) is comprised of the substrate (10). A spring (28) is a first clamping arm (22) and a second clamping arm (24). The first clamping arm (22) is opposite to the second clamping arm (24) and is respectively disposed with a pivoting shaft (26) disposed between the first clamping arm (22) and the second clamping arm (24). And the two ends of the spring (28) are respectively connected to the first clamping arm (22) and the second clamping arm (24). It should be noted that one side of the first clamping arm (22) extends outwardly with a protruding first pushing portion (30). One side of the second clamping arm (24) extends outwardly with a second pushing portion (32) protruding.
