Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a mounting device for a detector in a ring spring type force meter.

(Prior art) In order to attach a detector such as a dial gauge or a linear gauge to the ring body of this type of force meter, as shown in FIG. Screw the screw f screwed onto the lower part of the detector b into the screw hole e of the support piece d screwed into the piece c to connect the detector b to the ring body a, and attach the screws f to the top and bottom of the support piece d, respectively. Anti-loosening nuts g and h were applied.

(Problems to be solved by the invention) When using the above conventional detector as a detector by converting it to a dial gauge or linear gauge, or when replacing it with another gauge of the same type in the event of a failure, and when storing and carrying it. When attaching or detaching the detector b used, remove the detector b from the space between the support piece and the upper inner surface of the ring body by rotating the locking nuts g, h and the support piece c, and when connecting them. It is also necessary to screw support piece c and nuts g and h to support detector b.

Originally, the ring main body and the detector combined with it each have their own characteristics, and when used, they are used in the best combination of characteristics. Therefore, the detector in use must be removed and then combined and used again. It is extremely difficult to combine and combine the characteristics to their original best state, and in the conventional method described above, which is connected by the rotation of a spiral, even a small amount of rotation causes an instrumental difference. There is a disadvantage that the original state cannot be reproduced.

Furthermore, it is extremely troublesome to rotate the plurality of parts appropriately each time the detector is attached or detached.

(Means for solving the problem) The present invention eliminates the above-mentioned conventional inconveniences, and sets the distance between the upper inner surface of the ring body and the receiving surface of the detector to be always constant, and the charging position of the detector is The detector is fixed and held at a fixed position by the rotation of one rotating member, and the screw attached to the lower inner surface of the ring body of the annular spring type force meter is designed to prevent loosening. The upper surface of the support piece screwed in through a locking nut serves as a seat, and the detector, which has a joint piece with a protruding flange at the lower end, is placed between the inner surface of the upper part of the ring body and the upper seat surface of the support piece. In between, a centering protrusion provided at the center of the lower surface of the protruding flange is fitted into a recess formed at the center of the upper receiving surface of the support piece, and the protruding flange is supported on the receiving surface and inserted;
A screw cylinder having an opening for inserting the lower part of the joint piece and the flange from the side from the center of the top plate to the side is screwed onto the upper part of the support piece, and the flange is seated by the screw tube. The detector is removably attached to the ring body by pressing against the ring surface.

(Function) In the present invention, if the detector is attached to the ring body of the force meter in the best operating position and the position of the support piece screwed into the threaded piece is fixed using the double nut mechanism in that state, the support piece can be fixed. The distance between the upper end seating surface and the upper inner surface of the ring body remains constant. Under these conditions, if the detector is inserted within the space and the protrusion of the joint piece attached to the bottom is supported on the upper end receiving surface of the support piece, the detector will be installed in the best operating position. Then, the detector is immovably connected to the ring body by turning the threaded cylinder screwed onto the upper part of the support piece to press down on the protruding flange and fixing it to the seat under pressure.
In addition, the detector can be freely removed by loosening the lower pressure of the flange by rotating the screw cylinder. Accurate centering is achieved by fitting, and the protruding flange of the detector fitting piece can be easily inserted and removed from the side through the opening provided from the top to the side of the screw cylinder, making operation easier. is easily performed.
In this way, the insertion interval of the detector remains unchanged due to the fixation of the support piece, so if the vertical length of the detector is constant, the mounting condition when installing and removing it can be obtained by reproducing the same conditions. The detector can be attached and detached by the release operation, and when the same detector is repeatedly attached and detached, it can always be attached in the best operating condition, and the same type of detector or different type of detector, e.g. Even when replacing a dial gauge with a linear gauge, if the vertical length of the gauge is the same, it can be easily attached and detached by simply rotating the screw tube.

In addition, when replacing the detector with another one, adjust the push amount of the detection operation by loosening the double nut mechanism and rotating the support piece to move it up and down at the beginning of the replacement, depending on the difference between each detector. The position of the catch may be corrected to obtain the best condition, and the above-mentioned correction is not required when the detector is subsequently attached or detached.

(Example) Embodiments of the present invention will be described with reference to the drawings.
