A bracket 102 is fixed to the tip of the arm 101, and a ball screw 105 is connected to a motor 104 fixed to the upper end 103 of the bracket 102.
A spline shaft 107 arranged parallel to the ball screw 105 is connected to a nut 106 that is screwed onto the ball screw 105, and a work tool 1 such as an air chuck is attached to the lower end of the spline shaft 107.
08 are connected to each other, and the rotation of the motor 104 moves the nut 1-106 screwed into the ball screw 105 up and down, and at the same time, the spline shaft 107 can be raised and lowered.

(Technical Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems, and involves fixing a motor to the tip of a working arm, fitting a tool shaft into a hollow motor shaft, and screwing the two together. The spline part formed at the bottom of the tool shaft is inserted into a spline bearing that is fixed integrally with the work arm, which reduces the size and weight of the device itself, prevents strain on the work arm, and allows smooth movement. The purpose is to

(Example) Hereinafter, a detailed explanation will be given based on the illustrated example. 1
The case 2 is fixed to the tip of the work arm, and the motor 3 is fixed to the upper part of the case 2. The motor shaft 4 of this motor 3 is hollow, screws 4a and 4b are carved into the upper and lower parts of the hollow motor shaft 4, a tool shaft 5 is inserted into the hollow motor shaft 4, and screws 4a and 4b are carved into the upper part of the tool shaft 5. The provided screw 5a is screwed together with the screws 4a and 4b of the hollow motor shaft 4, and the spline 5b formed at the lower part of the tool shaft 5 is fixed to the tip of the working arm 1.The spline bearing 6 is fixed to the lower part of the case 2.
It is inserted into the shaft and is pivoted so that it can move up and down. A limit switch 7.8 is fixed to the upper part of the case 2, and a switch operating protrusion 9 is attached to the upper part of the tool shaft 5.
