Abstract

PURPOSE:To prevent a lead pin from jumping, by disposing a jump preventing plate in the opposite side of the lead pin against a lead screw, and making a dimension between the lower surface of the lead pin and the upper surface of the jump preventing plate smaller than the outer diameter size of the lead screw. CONSTITUTION:A lead screw 3 is insertedly supported by a lead pin 2 and a pressure spring 4, and a jump preventing plate 5 is fixed to a member 1 in a position on which the size of B becomes less than that of A. Thus, as the jump preventing plate 5 strikes against the lead screw 3 before the lead pin 2 is removed from the groove of the lead screw 3, so that the jumping of the lead pin 2 can be prevented.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、リードスクリューを用いた移動機構における
リードピンの飛び防止装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lead pin fly prevention device in a moving mechanism using a lead screw.

〔発明の概要〕[Summary of the invention]

ードピンの飛びを防止したものである。In the present invention, in a moving mechanism using a lead screw, a highly rigid fly-prevention plate fixed to the same member as the lead pin is disposed on the opposite side of the lead screw to the lead pin, and the lower surface of the lead pin and the upper surface of the fly-prevention plate are arranged. The dimension between 'r is made smaller than the outside diameter of the IJ-toss screw, and the fly-out prevention plate makes contact with the lead screw before the lead pin comes out of the groove of the lead screw, thereby preventing the lead pin from flying off.

〔従来の技術〕[Conventional technology]

従来、リードスクリューを用いた移動機構は、図２に示

バネ４で挾持する構造が知られていた。Conventionally, the movement mechanism using a lead screw is the Lead Screw!, as shown in Figure 2. A structure in which it is held between a 1t lead pin 2 and a presser spring 4 has been known.

The conventional structure had the problem that when a large impact was applied, the elasticity of the presser spring was overcome by the impact and the lead pin flew out of the groove of the lead screw. Therefore, the present invention solves these problems of the conventional structure. In order to solve this problem, the purpose of the present invention is to obtain a lead pin fly prevention device that enables smooth operation without causing the lead pin to fly out of the groove of the lead screw even when a large impact is applied.

〔問題点を解決するための手段〕[Means for solving problems]

外径寸法より小さくし念事を特徴とする。The lead pin fly prevention device of the present invention, in a moving mechanism using a lead screw, has a high rigidity jump prevention plate fixed to the same member as the lead pin on the opposite side of the lead pin to prevent the lead pin from flying off. The feature is that the dimension between the prevention plate and the upper surface is made smaller than the outer diameter dimension of the lead screw.

能となるのである。When an impact is applied to the lead pin fly prevention device configured as described above, 2. If the lead pin attempts to fly out of the groove of the lead screw and moves, the fly prevention plate fixed to the same member as the lead pin will also be the same as the lead pin. Before the lead pin moves in the direction of the lead screw and comes off from the groove of the lead screw, the fly prevention plate makes contact with the lead screw and stops the movement of the lead pin, thereby making it possible to prevent the lead pin from flying off.
