Abstract

PURPOSE: To efficiently install a hand device by spirally cutting a reamer bolt hole in a supporting base at the tip of a robot arm and boring a reamer hole matching with the reamer bolt hole in a mounting base in the hand device to be installed and fixed to the supporting base. CONSTITUTION: For mounting and fixing a hand device 4 to an arm, a mounting base 9 in the hand device 4 is placed so as to overlap a supporting base 3 so that its reamer hole 11 is matched with a reamer bolt hole 12 formed in the supporting base 3 at the tip of the arm. A reamer bolt 13 is screwed into the reamer hole 11 and the reamer bolt hole 12 matched with each other, so that the hand device 4 is positioned in the robot arm.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application) The present invention relates to an improvement in an installation device for an industrial robot hand that fixes a hand device to an arm of an industrial robot.

(Prior Art) Figures 3 to 7 show the installation equipment of a conventional industrial robot hand, in which (1) is the main body of a vertically articulated robot, and (2) is this main body (1). (3) a vertically reciprocating swing arm whose base end is pivotally connected to the upper part of the arm;
is pivotally attached to the tip of this arm (2), and the hand device C4
), which has a bolt hole (8) on its lower surface into which a bolt (5) is screwed, as shown in Figure 6.7.
A plurality of reamed holes (8) into which the positioning pins (7) are fitted are regularly bored so as to face each other (see Fig. 5).

The inner surface of the bolt hole (6) is formed with a female thread, and the inner surface of the reamed hole (8) is reamed and formed accurately. However, in (9), the hand device (4) is attached to the base, and the above-mentioned bolt (6) is attached to the base (9).
The bolt hole (!O) that screws into the above positioning pin (7)
The reamed hole (11) that fits into the hole (6), (
A plurality of bolt holes (10) are provided corresponding to the bolt holes (8) (see Fig. 6), and the bolt holes (10) are formed into round holes with a slightly larger diameter than the bolt holes (6).
11) is formed to have the same diameter as the reamer hole (8).

The conventional mounting device with the above configuration is mounted on the base (9
), its pores (10), (u) are the supporting base (3)
Align the multiple holes (6) and (8) on the lower surface with the supporting base (3), and fit the positioning bottle (7) into the reamed hole (11) and reamed hole (8) using a hammer or the like. At the same time, insert the bolt (5) into the bolt hole (l).
O) and bolt hole (6), and attach the hand device (
4) is positioned and fixed at the tip of arm (2).

(Problems to be Solved by the Invention) Conventional robot hand installation devices were configured as described above, so in order to position and fix the hand device (4) to the tip of the arm (2), a support base ( 3) and installation requires drilling and reaming of a large number of bolt holes in the base (9), which poses a problem in that installation requires a large amount of time for manufacturing and processing the device. In addition, the hand device (4
), there was a problem in that assembly, disassembly, and maintenance work was delayed due to the structure of the device.

The present invention has been made in view of the above points, and an object of the present invention is to provide a device for mounting an industrial robot hand that has a simple mounting structure and is extremely easy to handle in various ways.

(Means for solving the problem) In order to achieve the above-mentioned object, in the present invention, a hole for a reamer bolt is formed in the support base provided at the tip of the robot arm, and a hole for the reamer bolt is formed in the support base provided at the tip of the robot arm. Attachment of the fixed hand device is characterized in that a reamed hole that matches the above-mentioned hole is bored in the base, and the base is overlappingly screwed onto the above-mentioned hand support base via a reamer bolt.

(Function) In the present invention, the hand device is attached by superimposing the base on the support base so that its reamer hole is aligned with the hole for the reamer bolt on the lower surface of the supported base, and by screwing the reamer bolt into the alignment hole. This allows the hand device to be easily positioned and fixed to the arm of the robot.

(Embodiment) In the following, the present invention will be explained with reference to an embodiment in Figs. ) The large diameter part (12
a) and a small diameter portion (12b). This large diameter portion (12a) is reamed so that the reamed portion (13a) at the rear of the reamer bolt (13) fits without any gap, and the small diameter portion (12b) is carved on the surface of the tip of the reamer bolt (13). Installed male screw part (13b)
A female thread is formed on the inner surface so that the two can be screwed together. On the other hand, the mounting base (9) of the band device (4) has a reamed hole (11) similar to the conventional example and the reamed bolt hole (12).
), and the diameter thereof is formed to be the same as the large diameter portion (12a) of the reamer bolt hole (12).

However, in order to attach and fix the hand device (4) to the arm (2), the base (9) must be attached to its reamed hole (
11) is aligned with the reamer bolt hole (12) of the support base (3) of the arm (2), and the reamer bolt (13) is inserted into the reamer hole (11) and the reamer bolt using a spanner or the like. The reamer bolt (13), which only needs to be screwed into the hole (12), has a reamer part (13a) that has a positioning function and a male thread part (13b) that has a fastening function. Since it has the functions of a bolt (5) and a positioning pin (7), the support base (3) and the drilling work required for attachment to the base (9) can be reduced.

Therefore, the installation can shorten the work process required for manufacturing and processing the device, as well as the work time required for disassembling, assembling, and maintaining and inspecting the hand device (4). It becomes possible to reduce the number of points.

(Effects of the Invention) As described above, according to the present invention, it is possible to significantly improve execution efficiency and provide an apparatus for attaching an industrial robot hand that is structurally superior.
