この考案は、例えばプログラムコントローラの
各ユニツトをベースユニツトに固定するためのユ
ニツトの取付装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a unit mounting device for fixing each unit of a program controller to a base unit, for example.
第１図はプログラムコントローラの斜視図であ
り、図において、１は電源ユニツト、２は中央処
理装置ユニツト（CPUユニツト）、３は入出力ユ
ニツト等のモジユールユニツトを示す。
FIG. 1 is a perspective view of the program controller. In the figure, 1 is a power supply unit, 2 is a central processing unit (CPU unit), and 3 is a module unit such as an input/output unit.
以下、各ユニツト１〜３を単にユニツトとい
う。 Hereinafter, each unit 1 to 3 will be simply referred to as a unit.
上述したユニツト１〜３はベースユニツト４
に、ユニツト１〜３を貫通する取付ボルト６で取
り付けられている。 Units 1 to 3 mentioned above are base unit 4.
It is attached to the unit with a mounting bolt 6 passing through the units 1 to 3.
第２図，第３図は従来のユニツトの取付装置を
示す図であり、ユニツト１〜３はいずれも中空の
箱形形状となつており、先端部にのみねじ部５を
有する取付ボルト６をユニツト１〜３の上面の穴

８にあけた穴９，１０を通してベースユニツト４
のねじ穴（図示省略）に螺合させ、ユニツト１〜
３をベースユニツト４に固定している。 Figures 2 and 3 are diagrams showing conventional unit mounting devices. Units 1 to 3 all have a hollow box shape, and have a mounting bolt 6 with a threaded portion 5 only at the tip. The base unit 4 is inserted through the hole 7 on the top surface of the units 1 to 3, and passed through the holes 9 and 10 made in the bottom surface of the units 1 to 3 and the seat 8.
Screw it into the screw hole (not shown) in the unit 1~
3 is fixed to the base unit 4.
この場合、取付ボルト６は頭部下面からねじ部
５までの長さ、つまり基準寸法T0がユニツト１
〜３の奥行寸法T1よりも短いため、取付ボルト
６のねじ部５の長さT2は締付余裕T3を含んでい
る。 In this case, the length of the mounting bolt 6 from the bottom surface of the head to the threaded part 5, that is, the standard dimension T 0 is the unit 1.
3, the length T2 of the threaded portion 5 of the mounting bolt 6 includes the tightening margin T3 .
したがつて、取付ボルト６をねじ部５の締付余
裕T3まで螺合させると、締付力が強くなりすぎ
てユニツト１〜３にたわみ変形が発生する恐れが
あつた。 Therefore, when the mounting bolt 6 is screwed up to the tightening margin T3 of the threaded portion 5, the tightening force becomes too strong and there is a risk that the units 1 to 3 may be bent.
そこで、従来はユニツト１〜３にたわみ変形が
発生するのを防止するため、第２図ではユニツト
１〜３の上部内面と受座８との間に両者間の長さ
と略等しい長さのカラー１１を配設し、余分な締
付力を受ける構成としている。 Therefore, in order to prevent bending deformation from occurring in the units 1 to 3, conventionally, in FIG. 11 is arranged to receive extra tightening force.
また、第３図では取付完了時点で受座８の上面
に当接する座金１２を取付ボルト６に取り付け、
座金１２が受座８の上面に当接することにより、
余分な締付力を受ける構成としている。 In addition, in FIG. 3, when the installation is completed, the washer 12 that contacts the upper surface of the catch seat 8 is attached to the mounting bolt 6,
By the washer 12 coming into contact with the upper surface of the catch seat 8,
It is configured to receive extra tightening force.
従来のユニツトの取付装置は以上のように構成
されているので、第２図の場合ではカラー１１を
必要とし、第３図の場合ではねじ部５と座金１２
との間を細径６ａに加工する必要があり、かつ、
取付工数がかかるという問題点があつた。 Since the conventional unit mounting device is constructed as described above, the collar 11 is required in the case of FIG. 2, and the threaded part 5 and washer 12 are required in the case of FIG.
It is necessary to process the space between the two to have a narrow diameter 6a, and
There was a problem that it took a lot of man-hours to install.
この考案は、上記のような問題点を解消するた

置を得ることを目的とする。
This idea was made to solve the problems mentioned above. By making the standard dimensions of the mounting bolts approximately equal to the depth dimension of the unit, the unit can be tightened without using a collar. To provide an inexpensive mounting device for a unit that can be mounted and fixed on a base unit while preventing deflection.
以下、この考案の一実施例を図について説明す
る。
An embodiment of this invention will be described below with reference to the drawings.
第４図において、第１図〜第３図と同一部分に

法T0をユニツト１〜３の奥行寸法T1と略同一と
し、取付ボルト６の頭部とユニツト１〜３との間
にばね座金１３を介在させている。 In Fig . 4, parts that are the same as those in Figs . A spring washer 13 is interposed between the head of unit 6 and units 1 to 3.
次に、ユニツト１〜３のベースユニツト４への
取り付けについて説明する。 Next, the attachment of units 1 to 3 to base unit 4 will be explained.

と、ストツパとして機能し、その反力が手に伝わ
り締付完了を知ることができる。 Pass the mounting bolt 6 fitted with the spring washer 13 through the holes 7, 9, 10 of the units 1 to 3 and the hole 10 of the catch seat 8, and while pressing and deforming the spring washer 13 with the head of the mounting bolt 6, tighten the threaded portion. The units 1 to 3 are attached to the base unit 4 by screwing the screw portion 5 into the screw hole (not shown) of the base unit 4 until the boundary a between the base unit 5 and the reference dimension T 0 reaches the top surface of the base unit 4. Fix it. Furthermore, when the boundary a (incompletely threaded portion) reaches the upper surface of the base unit 4, it functions as a stopper, and the reaction force is transmitted to the hand, allowing the user to know when the tightening is complete.
ばね座金１３はねじ部５の螺合時に変形するこ
とによつてユニツト１〜３に強い押圧力が加わる
ことを防止するとともに、締付完了時に弾性復元
力によつてユニツト１〜３の保持，振れ止めおよ
び緩み止めの機能を有するものである。 The spring washer 13 prevents strong pressing force from being applied to the units 1 to 3 due to deformation when the screw portion 5 is screwed together, and also holds the units 1 to 3 by elastic restoring force when the tightening is completed. It has the functions of preventing steady movement and preventing loosening.

くなる。 If the mounting bolt 6 is accidentally screwed into the threaded part 5,
Even if more torque than necessary is applied to the base unit, the unthreaded portion of the mounting bolt 6 will not thread into the base unit 4 because the incompletely threaded portion at boundary a will not screw into the screw hole of the base unit 4 and will act as a stopper. Before entering the screw hole of unit 4, the receiving groove at the tip of the driver on the head of the mounting bolt 6 was destroyed, making it impossible to turn the mounting bolt 6 with a screwdriver, and the screwdriver was unable to turn the mounting bolt 6.
There is no need to apply strong pressure that may cause the material to bend.

As described above, according to this invention, the standard dimensions of the mounting bolt are made approximately the same as the depth dimension of the unit,
When the installation is complete, the spring washer is pressed and deformed so that the boundary between the threaded part of the mounting bolt and the standard dimensions comes into contact with the top surface of the base unit and functions as a stopper, allowing you to know when the tightening is complete by increasing the rotational force of the bolt. . As a result, there is no need to provide a special stopper to the bolt, and the bolt can be obtained with a simple structure and at low cost. It also has the effect of preventing deflection of the unit due to excessive tightening and securely fixing the unit to the base unit.
