るものである。 In the figure, 1 is a carriage, for example,
It is connected to an operating member such as a screw of an injection molding machine. Reference numeral 2 denotes a measuring rod, which is fixed to the carriage 1 and usually consists of a polygonal column such as a hexagonal column. 3
is a detection member, which is slidably fitted onto the measuring rod 2, and can be locked in any position by a locking means 4 such as a thumbscrew, and the detection member on the surface of the detection member is Cams 5 are formed at appropriate locations. A micro switch 6 is operated by the cam 5 and is fixed to the base 7. Reference numeral 6a designates an operating lever of the microswitch, which is provided in a protruding manner so as to be able to come into contact with the cam 5. A scale 8 is engraved on the measuring rod 2, and the detection member 3 is moved up and down in accordance with the scale 8 to appropriately set the locking position.

ものである。 Therefore, when the actuating member (not shown) is displaced by a certain amount, the measuring rod 2 aligns with the actuating member,
The actuating lever 6a of the micro switch 6 is pressed by the cam 5 of the detection member 3, and the amount of displacement is detected.
ところで、上記従来の変位検出装置において

設された記号等が小さくて読取りにくいという欠
点があつた。 By the way, in the above-mentioned conventional displacement detection device, since the scale is directly engraved on the surface of the measuring rod, the engraving work is very complicated.
Furthermore, since the surface area on which the scale is engraved is small, it is not possible to clearly engrave symbols, etc., and furthermore, the engraved symbols are small and difficult to read.
更に、検出部材の摺動によつて目盛部分が摩粍
するので、長期間使用すると、目盛等が不鮮明に
なるという難点があり、該目盛が摩粍した際に
は、計量桿を交換しなければらないという不利点
があつた。 Furthermore, since the scale part wears out due to the sliding of the detection member, there is a problem that the scale etc. becomes unclear after long-term use, and when the scale wears out, the measuring rod must be replaced. The disadvantage was that it did not release.
又、検出部材を計量桿に係止するときは、目盛

置個所との関係でカムの形成に不都合をきたす場
合があるという問題点もあつた。 Furthermore, when locking the detection member to the measuring rod, the detection member must be locked on a side other than the side on which the scale is engraved in order to prevent damage to the scale. Among them, there was a problem in that there was a limit to the side surface on which the cam could be formed, and that the formation of the cam could be inconvenient due to the location where the microswitch was installed.

在に係止される。 A detection member 3 having a cam 5 formed on at least one side is fitted and locked on the measuring rod 2, and the other side of the member 3 on which the cam 5 is not formed is the scale frame 9. The detection member 3 is removably locked to the measuring rod 2 by a locking means 4 such as a thumbscrew on the other side.
１３は検出部材３に付された矢印であり、前記
目盛１１を指向している。 Reference numeral 13 denotes an arrow attached to the detection member 3, pointing toward the scale 11.
尚、他の構成要素は第１図において同一の符号

効果がある。 As described above, this invention includes a measuring rod connected to an actuating member via a carriage, a detecting member slidably locked to the measuring rod, and a micro switch operated by the detecting member. In the displacement detection device for an actuating member, a scale frame having a window in the center and having graduations along the longitudinal direction of the measuring rod is attached to the measuring rod so that the detecting member faces into the window. With this configuration, it is possible to omit the complicated work of carving scales on the measuring rod, and to attach the scales to a separate scale frame very easily by printing.Moreover, the size of the scale frame can be Since the can be freely selected, symbols etc. can be printed large and clearly, and the scale can be read extremely easily and accurately, which is an excellent effect.
又、検出部材が目盛部分を擦過することがない
ので、該目盛部分が摩粍することがなく、長期間
の使用に耐えるという利点がある。 Furthermore, since the detection member does not rub against the scale portion, the scale portion does not wear out and has the advantage of being durable for long-term use.
しかも、目盛部分が何等かの理由で損傷した場
合にも、目盛枠のみを交換すればよく、計量桿は
そのまま使用でき、実用上非常に有益である。 Moreover, even if the scale portion is damaged for some reason, it is only necessary to replace the scale frame and the measuring rod can be used as is, which is very useful in practice.
その上、計量桿に目盛枠を取付ける側面で検出
部材を計量桿に係止するので、検出部材の周側面
のうちカムを形成することができる側面の数が多
くなり、カムの個数及びカムを形成する側面の選
択の自由度が広くなるという効果もある。 Furthermore, since the detection member is locked to the measurement rod at the side surface on which the scale frame is attached to the measurement rod, the number of side surfaces on which cams can be formed among the circumferential surfaces of the detection member increases, and the number of cams and the number of cams can be increased. Another effect is that the degree of freedom in selecting the side to be formed is increased.
