Problems solved by technology

In addition, in the case of using an electromagnet, when the size of the bolt changes, the bolt may not be properly transferred in response to this, resulting in low versatility.
[0006] In addition, the side orientation of the head of the bolt fed from the linear feeder is often disordered.

Embodiment Construction

[0024] Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

[0025] figure 1 It is a figure which shows the structure of the bolt supply system S to which the grasping apparatus 1 of this embodiment was applied. figure 2 It is a side view of the holding device 1 .

[0026] The bolt supply system S includes: a feeder 5 for arranging and sending out bolts B, which are parts having hexagonal sides in plan view; a holding device 1 for holding the bolts B sent out from the feeder 5; A robot 6 that moves the holding device 1 ; and a control device (not shown) that controls them.

[0027] The feeder 5 arranges and unloads a plurality of bolts B loaded into a container (not shown) along a linear rail 51 . Each bolt B has its shaft portion BA inserted into the rail 51 and its head BH is mounted on the rail 51. figure 1 Ships from the left side to the right side.

[0028] The grasping device 1 is attached to the distal e...

Abstract

An objective is to provide a holding device capable of holding a hexagonal part at a nearly fixed orientation in a plan view by a simple structure. A holding device 1 holds a bolt B by a left claw member 32L and a right claw member 32R. A left recessed portion 34L and a right recessed portion 34R in a recessed manner toward the bolt B in plan view are respectively formed in inner side end portions33L and 33R facing the bolt B, of the claw members 32L and 32R, a pair of protruding portions 36L and 37L and a pair of protruding portions 36R and 37R protruding toward the bolt B are respectively formed in the portions 34L and 34R, the distances ra and rb from a center O to the portions 36L and 37L are equal in each of the claw members 32L and 32R, and the protrusion interval [delta] is from d / (square)root 3 to d.

Description

technical field [0001] The present invention relates to holding devices. More specifically, it relates to a gripping device for gripping parts such as bolts and nuts having hexagonal side surfaces in plan view. Background technique [0002] A large number of bolts are used in the manufacture of vehicles. Therefore, an assembly line for a vehicle is equipped with: a fastening robot that fastens bolts to workpieces; a feeder that arranges and transports the bolts; Handover robot for fastening robot. [0003] In addition, the feeder arranges and delivers a plurality of bolts in a predetermined posture. For example, the feeder shown in Patent Document 1 has a linear feeder for arranging a plurality of bolts by inserting the shafts of the bolts between the rails and bridging the heads of the bolts between the rails. its sent. [0004] In addition, the delivery robot holds the head of the bolt sent out from the linear feeder of the feeder, and transports it to the fastening r...
