Description

Industrial machine and method for assembling the same Technical Field The present disclosure relates to industrial machinery and methods of assembling the same. Background A robot is known that includes a second arm including a housing in which a reduction gear or the like is housed, and a cover attached to an opening surface of the housing (see, for example, patent document 1). The housing and the cover in this case are supported by the first single arm and the second single arm, respectively, and positioning when the cover is mounted to the housing is performed by operating the second single arm. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2000-176877 Disclosure of Invention Problems to be solved by the invention However, when the robot does not have the above-described structure, the operator must hold the cover with one hand, maintain a state of positioning it at a prescribed position, and fix it to the housing with the other hand. The operator is particularly burdened when the mass of the cover is large. Therefore, in an industrial machine such as a robot, it is desired to make it easier to perform the mounting work of two parts configured to be detachable. Solution for solving the problem One aspect of the present disclosure is an industrial machine including a first member including a mounting surface disposed at an angle with respect to a horizontal direction, and a second member including a mounted surface capable of being brought into close contact with the mounting surface, wherein the first member or the second member includes at least one support protrusion at a first position where the mounting surface is brought into close contact with the mounted surface, the support protrusion is configured to support the second member from above against the first member so as not to be able to come off, and the first member and the second member are capable of being fixed to each other at the first position or at a second position where the mounted surface is displaced along the mounting surface while maintaining a supported state by the support protrusion.

Detailed Description An industrial machine in one embodiment of the present disclosure is described below with reference to the accompanying drawings. The industrial machine in the present embodiment is, for example, a vertical six-axis multi-joint robot (hereinafter referred to as a robot 100). As shown in fig. 1, the robot 100 includes a base 10 and a rotating body 20, the base 10 is provided on a surface to be installed such as a horizontal floor, and the rotating body 20 is supported rotatably about a vertical first axis J1 with respect to the base 10. The robot 100 includes a first arm 30, and the first arm 30 is supported rotatably about a horizontal second axis J2 with respect to the rotating body 20. The robot 100 further includes a second arm (not shown) rotatably supported with respect to the distal end of the first arm 30, and a triaxial wrist unit (not shown) attached to the distal end of the second arm. The rotary body 20 includes a case (first member) 21 and a cover (second member) 22, the case 21 having an opening 21a, the cover 22 being detachably attached to the case 21 and closing the opening 21a in an openable and closable manner. The housing 21 is supported rotatably about the first axis J1 with respect to the base 10 via a bearing, a speed reducer, and the like, not shown. The housing 21 supports the first arm 30 via a speed reducer or the like, not shown, so as to be rotatable about the second axis J2. A motor (not shown) for driving the rotary body 20 with respect to the base 10, a motor M for driving the first arm 30 with respect to the rotary body 20, and the like are accommodated in a space surrounded by the case 21 and the cover 22. As shown in fig. 1 and 2, the opening 21a is opened obliquely upward with respect to the horizontal ground. As shown in fig. 3, a strip-shaped mounting surface 21s extending along the entire circumference is disposed obliquely upward around the opening 21 a.
