Abstract

PROBLEM TO BE SOLVED: To provide a stand base capable of flexibly attaching a measuring instrument to a magnet stand.SOLUTION: A stand base 10 for a magnet stand includes: a base body 12 of a rectangular parallelepiped shape; a cock 14 arranged on a front 12a of the base body 12 and turning on/off magnetic force to be applied to the bottom of the base body 12; an upper surface screw hole 16 formed on an upper surface 12b of the base body 12 so that a male screw of an arm for attaching the measuring instrument is screwed into the screw hole; and a side face screw hole 18 formed on a side face 12c of the base body 12 so that the male screw of the arm is screwed into the screw hole.

Description

  The present invention relates to a stand base of a magnet stand that fixes a measuring instrument at an arbitrary position.

  For example, a magnet stand is used to fix a measuring instrument such as a dial gauge at an arbitrary position in order to inspect a parallel state or a right angle with respect to a reference plane of a machined product mounted on a certain apparatus.

  The magnet stand is coupled to a stand base (magnet base), a first arm that is screwed into a screw hole formed on the upper surface of the stand base, and to the first arm via an articulation member so as to be vertically movable and tiltable. A measuring instrument such as a dial gauge or a micrometer is attached to one end of the second arm via a joint member and fixed in an arbitrary posture (for example, Japanese Patent Laid-Open 7-311005).

  The stand of the magnet stand can be turned ON / OFF the magnetic force acting on the bottom surface of the base body by storing the permanent magnet in the rectangular parallelepiped base body and rotating the cock provided on the front surface of the base body. ing. On the upper surface of the base main body, an upper surface screw for vertically mounting the first arm having the male screw is formed.

  When measuring an object to be measured with a measuring instrument such as a dial gauge or micrometer using a magnetic stand, bend the joint member and adjust the position and angle of the second arm relative to the first arm. Measure in a convenient state.

  However, since the stand base of the conventional magnetic stand has a structure in which the first arm is vertically attached to the screw hole formed on the upper surface, there is not enough freedom for mounting the measurement instrument, and the measurement instrument is not necessarily in a convenient state. There is a problem that it cannot be adjusted.

  The present invention has been made in view of these points, and an object of the present invention is to provide a stand base of a magnet stand that can be flexibly mounted with a measuring instrument with a sufficient degree of freedom with respect to the magnet stand. It is.

  According to the present invention, there is provided a stand base of a magnet stand, a rectangular parallelepiped base body, a cock that is disposed on the front surface of the base body and that turns on / off the magnetic force acting on the bottom surface of the base body, and a measuring instrument. An upper surface screw hole formed on the upper surface of the base body to which the male screw of the arm to be fitted is screwed, and a side screw hole formed on the side surface of the base body to which the male screw of the arm is screwed. A stand base for the magnetic stand is provided.

  According to the stand base of the magnet stand of the present invention, in addition to the upper surface screw hole formed on the upper surface of the stand base, a side screw is formed on the side surface of the stand base to which the male screw of the arm for mounting the measuring instrument is screwed. Therefore, the arm on which the measurement instrument is mounted can be conveniently fixed to the side surface of the stand base, and the measurement instrument can be flexibly mounted on the magnet stand with sufficient flexibility according to the convenience.

It is a perspective view of the stand base of the magnet stand which concerns on this invention embodiment.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Referring to FIG. 1, a perspective view of a stand base (magnet base) 10 is shown. The stand base 10 has a rectangular parallelepiped base body 12 in which a permanent magnet is accommodated.

  A cock 14 for turning on / off the magnetic force acting on the bottom surface of the stand base 10 is attached to the front surface 12 a of the base body 12. When the cock 14 is rotated to the vertical position, the magnetic force is interrupted, and when the cock 14 is rotated to the horizontal position, the magnetic force acts on the bottom surface of the stand base 10 so that the stand base 10 can be fixed on the stage or table by the magnetic force.

  An upper surface screw hole 16 into which a male screw of a first arm (not shown) of the magnet stand is screwed is formed on the upper surface 12 b of the base body 12. A side screw hole 18 into which the male screw of the first arm is screwed is also formed on one side surface 12 c of the base body 12.

  In order to mount a measuring instrument such as a dial gauge or a micrometer on the magnet stand using the stand base 10 of the above-described embodiment, first, a male screw of a first arm (not shown) is first screwed into the upper surface screw hole 16. One arm is fixed vertically to the stand base 10, and the second arm is attached to the first arm via an articulation member so as to be movable and tiltable.

  Then, a measuring jig such as a dial gauge is attached to one end of the second arm via a joint member, and the measuring instrument is adjusted to the optimum position by adjusting the two joint members as appropriate, and the measurement object is measured. To implement.

  However, depending on the position of the object to be measured, the measurement instrument may not necessarily be adjusted to a convenient state by mounting the measurement instrument using the upper surface screw hole 16. In such a case, side screw holes 18 formed at right angles to the upper screw holes 16 are used.

  That is, the male screw of the first arm is screwed into the side screw hole 18 to fix the first arm in parallel with the stage to which the stand base 10 is fixed. Then, the second arm is attached to the first arm so as to be movable and tiltable via the joint member, and the measuring instrument is attached to one end of the second arm via the joint member.

  Thus, even when the measuring instrument cannot be adjusted to a convenient state by mounting the measuring instrument using the upper surface screw hole 16, the measurement is performed using the side screw hole 18 extending in a direction perpendicular to the upper surface screw hole 16. By attaching the instrument to the magnet stand, the measurement instrument can be adjusted to a state convenient for measurement.
