Problems solved by technology

However, if the robot described in Patent Document 1 is repeatedly maintained, the internal thread of the casing will be damaged, that is, the thread teeth will be crushed.
In this case, maintenance cannot be performed with the cover removed
In addition, since the cover is in a state of being removed, as a result, the drive mechanism is exposed, the frequency of maintenance increases, and safety cannot be ensured, resulting in the robot being unusable

Abstract

A robot includes an arm. The arm includes a long-shaped arm body having a storing section configured of a concave section which is formed to open to a side surface thereof; a driving mechanism which is stored in the storing section and has a motor; and a sealing section airtightly sealing the storing section. The sealing section includes a frame body which has a frame shape along an edge of the opening section opened to the side surface of the storing section and is adhered to the edge with adhesive, and has a plurality of female screws in which a plurality of bolts are screwed, respectively; a cover which is detachably installed on the frame body by the bolts which are screwed in the female screws and covers the storing section in a installed state; and a packing interposed between the frame body and the cover.

Description

technical field [0001] The present invention relates to robots. Background technique [0002] Conventionally, there is known a robot including a base and a plurality of arms supported so as to be displaceable with respect to the base and connected to each other (for example, refer to Patent Document 1). In the robot described in Patent Document 1, for example, one arm has: a casing as the arm main body; a motor, pulley, belt, etc. housed in the casing as a driving mechanism; and a cover covering the driving mechanism. A plurality of internal threads are formed on the housing. Then, the cover is fixed to the housing by screwing the bolts into the respective internal threads, that is, by the bolts. [0003] In addition, a gasket and a plate supporting the gasket are interposed between the casing and the cover, and these members are collectively fixed together with the cover by bolts. In this way, in the robot described in Patent Document 1, a so-called "joint fastening" met...
