本発明は、例えば、ダイヤルゲージ、リニアゲージ等の
側寸器の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in side gauges such as dial gauges and linear gauges.
この種の側寸器は、スピンドルをその一端が萱体外方に

ピンドルに伝達されたスピンドル移動量を移動量検出器
により電気信号に変換して取出すようになっている。This type of side measuring device has a spindle that is supported on a 4-shaped cliff body so that one end of the spindle protrudes outward from the shell body and is movable in the protruding direction. 'By imitation, a pushing force is always exerted on the spindle in the protrusion direction, and the amount of spindle movement transmitted to the spindle by contact with the object to be measured is converted into an electric signal by a movement amount detector and extracted. There is.

どが公知である。In addition, the movement amount detector is one that converts the amount of spindle movement into rotational displacement using a rack and pinion mechanism, and converts it into a pulse signal using a rotation detector, which is mainly used for custody measuring instruments such as dial gauges, or There is a known device which converts the amount of movement of the spindle into the number of mower stripes moved by a mower stripe generating mechanism and converts it into a periodic signal using a photoelectric detector, which is mainly used in side gauges such as linear gauges.
ところで、このような側寸器は、スピンドルの突出端を
下方に向けて使用するばかりではなく、上方あるいは横
方向に向けて使用する例も多い。Incidentally, such a side measuring device is often used not only with the protruding end of the spindle facing downward, but also with the protruding end of the spindle facing upward or in the lateral direction.
そうすると、重力の関係上スピンドルに加わる押力は、
スピンドルの配道方向によって異なることになり、例え
ば、上向に向けた場合の押力は押出し‘まねの押力より
もスピンドルの重量分小さく、逆に下方に向けた場合は
スピンドルの重量分大きくなる。この結果、スピンドル
の移動速度もスピンドルの配置方向によって当然異なる
ことになり、結局、スピンドルの配置方向で異なる応答
性をもつことになる。Then, the pushing force applied to the spindle due to gravity is
It differs depending on the direction of the spindle. For example, when facing upward, the pushing force is smaller than the pushing force for extrusion 'imitation' by the weight of the spindle, and conversely, when facing downward, it is larger by the weight of the spindle. Become. As a result, the moving speed of the spindle naturally differs depending on the direction in which the spindle is arranged, and as a result, the responsiveness differs depending on the direction in which the spindle is arranged.
したがって、例えば、スピンドルを上方に向けた状態を
基準にして、その状態で所定の応答性を持つように押出
し‘まねの強さを調整すれば、下方に向けて使用した場
合過大な速度でスピンドルが落下し、被測定体はもちろ
ん、側寸器自体に衝激的な力を生ずると共に、移動量検
出器の応答限界を越えて検出誤差を生ずる恐れがあり、
逆に下向の状態を基準にして調整した場合には、上向き
使用時に応答速度不足をまね〈ことになり、特に、長尺
側寸器では、スピンドルの自重が大になるためこのこと
が大きな問題点となっていた。Therefore, for example, if you adjust the strength of the extrusion imitation to have a predetermined response based on the state where the spindle is facing upward, if you use it with the spindle facing downward, it will cause the spindle to move at an excessive speed. may fall, creating an impact force not only on the object to be measured but also on the side measuring instrument itself, as well as exceeding the response limit of the movement amount detector and causing a detection error.
On the other hand, if the adjustment is made based on the downward position, the response speed will be insufficient when used in the upward direction.This is especially true for long side measuring instruments, as the weight of the spindle is large. This had become a problem.

である。In other words, this is a system in which a rack is fixed in the longitudinal direction of the spindle, and a speed-increasing gear supported in the case is meshed with this rack.This allows the spindle to move due to the moment of inertia of the speed-increasing gear. It was designed to meet resistance. In this case, the resistance of the speed increasing gear is the sum of not only the resistance corresponding to the movement acceleration of the spindle, but also the rolling friction resistance and windage resistance of the gear system, which increases as the movement speed increases. Furthermore, the greater the speed change, the more the change in the moving speed of the spindle is suppressed. however,
Another problem with this is that the moment the spindle comes into contact with the surface to be measured, the inertial energy of the speed increasing gear is transmitted to the spindle, giving an excessive measurement pressure between the spindle and the surface to be measured. Occur. In particular, when considering both upward and downward use, the extrusion of the spindle must be determined based on upward use, and in this case, the measured pressure in the downward direction becomes even more excessive. In order to eliminate the above-mentioned drawbacks, the present invention engages a spindle with a governor mechanism, the governor mechanism is supported rotatably through a case having a cross section, and a shaft portion protruding from the case is connected to the spindle. A plate member is fixed to the engaged rotating shaft and the shaft portion of the rotating shaft inserted into the case, and one end is supported at each end of the plate member, and a first plate member and a first plate member are connected to each other by a spring. When the moving speed of the spindle is about to exceed a predetermined value, the rotation of the rotating shaft of the governor mechanism that engages with the spindle increases, causing the first and second moving bodies to spring. It is moved outward against the force and comes into contact with the inner peripheral surface of the case, thereby generating a braking force.
The spindle is kept at a constant speed at all times.

Further, contacts 26' and 27' are provided protruding from the outer peripheral surfaces of the first and second movable bodies 26 and 27, and pins are provided on the first and second movable bodies 26 and 27, respectively. The three springs connecting 28 and 29 are always subjected to inward tension. Therefore, when the spindle 3 moves, the rotating shaft 16 rotates at a rotation speed proportional to the moving speed of the spindle, and as a result, the first and second moving bodies 26, 2
7 starts to swing outward due to the centrifugal force generated in accordance with the rotational speed, and swings to a position where the centrifugal force and the drag force of the spring 30 are balanced.

なるようにしておけばよいことになる。When the rotation speed reaches a predetermined number or more, the contacts 26' and 27' protruding from the first and second movable bodies 26 and 27 come into contact with the inner circumferential wall of the case 11, causing the rotation of the rotating shaft 16. This will prevent an increase in the number and thereby also an increase in the speed of movement of the spindle 3. In this way, the speed of movement of the spindle 3 is controlled by the governor mechanism 1, so when making adjustments, first, when the pushing force of the spindle is at its maximum and the spindle is facing upward, the necessary response is determined. It is sufficient to roughly adjust the extrusion 'simulation 4 so that the speed is the same, and also to set the governor mechanism 10 so that its upper limit speed becomes the required response speed.
