Abstract

PURPOSE:To make a work hour reducible, by clamping a spindle of the control ler pinched and clamped by a vice in rotating it at the setting torque, and installing a device, which performs conformity setting of the spindle, around a conveyor. CONSTITUTION:When a controller is pinched and clamped by a vice 12, a turn table 13 is rotated as far as 1/4 times and this controller 9 is conveyed up to a lower position of a nut runner 30 of a spindle conformity setter 3. And, with operation of an air cylinder 40, the nut runner 30 goes down as far as the specified stroke via a lifting plate 37, and the nut runner 30 operates in the point midway in its going down. If so, a spindle socket 32 goes down as being rotated and is fitted in the spindle, while a turning shaft gives rotation and stop motion of the setting condition to the spindle via the spindle socket 32, and it clamps the spindle at the setting torque, thus conformity setting takes place.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a fully automatic tightening device for control use that can fully automatically tighten the spindle of a controller and the tightening of a packing nut. BACKGROUND OF THE INVENTION In general, the spindle plays a very important role in regulating the waterfall basin among the functions of a controller (eg, a high-pressure lift valve, etc.).

Therefore, in order to stabilize the operation of the controller and to ensure good and reliable operation, after completing the assembly work of the spindle and related parts, it is necessary to attach the spindle and tighten the packing nut. must do the work.

That is, as shown in FIG. 9, the work of applying the spindle is controlled by <t! Tighten the box 61 of 1 m 60 with the mouthpiece 63 of the vise 62, and tighten the spindle 6 through the handle action.
5 is rotated and tightened with a set torque to improve the roundness of the fit between the male threaded portion of the spindle 65 and the female threaded portion 67 of the box body 61 that fits thereto, and to stabilize the stop. ing.

The tightening of the packing nut 69 is performed by rotating the packing holding nut 69 with a set torque using a spanner 68, as shown in FIG.
9 and the female screw portion 70 of the box body 61 that fits therewith.
The roundness of the fitting is made to be good, and the tightness of the seal is made to be good.

However, since each of the above-mentioned tasks is performed manually, it requires a keen sense and experience on the part of the worker, and unskilled workers may
For example, the degree of fit between the spindle 65 and the box body 61 may be poor, making it impossible to properly and reliably seat and separate the stopper body and the stopper seat, or the tightening force of the seal retaining nut 69 may be insufficient, causing the seal to come off. Problems such as leakage or excessive tightening force may occur, such as excessive tightening torque of the controller's knob, and it is difficult for only an experienced person with many years of experience to perform the work properly and reliably. It was elegant.

(Problems to be Solved by the Invention) The present invention was devised to solve the above-mentioned problems, and its purpose is to eliminate the work of attaching the controller spindle and tightening the packing retainer nut. The purpose of the present invention is to provide a fully automatic control equipment that can achieve full automation.
