The reference bar 2 forms a side wall portion with a pair of strips 2a, and the pair of strips 2a has a pair of sleeve-like upper and lower spacers 2b at four locations in the length direction with a pair of strips. It is fixed to 2a. In the reference bar 2, a rectangular groove 2c having a rectangular cross section is formed between a pair of strips 2a, and a vertical rectangular groove 2c is formed vertically.

The origin side reference pin 3 is attached to the reference bar 2 so that its position in the length direction is variable, and is locked to the reference surface K when indexing the target point.
The origin-side reference pin 3 is attached to the reference bar 2 in a first locking sleeve 10 in a vertical posture that is variable in position in the longitudinal direction and invariable in the vertical position, and a vertical through hole 10a of the first locking sleeve 10. A reference pin member 11 that is slidably inserted and has a head portion 11a having a larger diameter than the vertical through hole 10a at the upper end is provided. The first locking sleeve 10 and the reference pin member 11 are made of steel or stainless steel.

  The first locking sleeve 10 includes a rectangular tube portion 10b fitted in the rectangular groove 2c with almost no gap, and a pair of locking portions 10c integrally formed at the front and rear portions of the upper end portion of the rectangular tube portion 10b. And a vertical through hole 10a having a circular cross section is formed in the rectangular tube portion 10b.

However, when the set screw 16 is loosened, the second locking sleeve 14 can be moved along the reference bar 2. The second locking sleeve 14 is fixed at a position away from the first locking sleeve 10 by the preset distance D.

Next, the operation and effect of the target point indexing jig 1 will be described.
When indexing the target point T, as shown in FIG. 1, the first locking sleeve 10 of the origin side reference pin 3 is fixed to the reference bar 2, and the second locking sleeve 14 is fixed to the first locking sleeve 10. As shown in FIG. 2, the reference bar 2 is bridged between the two guide rods G, and the origin side reference pin 3 is guided from the right side. The rod G is brought into contact with the reference surface K on the right side of the rod G.

  However, at this time, the target point indexing fall pin 4 is removed from the second locking sleeve 14, and when the above preparation is completed, the target point indexing falling pin 4 is attached to the second locking sleeve 14. Inserted into the vertical through-hole 14a from above, when the inverted conical portion 4a reaches a height position of 20, 30 cm from the floor surface, the target point indexing drop pin 4 is allowed to fall freely. Then, since the tip of the inverted cone portion 4a collides with the floor surface to form an indentation, the indentation is set as the target point T.

  Since the above work can be performed by one worker, the target point T can be easily determined in a short time by one worker. Since the target point indexing fall pin 4 is employed instead of the weight, it is not necessary to wait until the stop like the weight, and the target point can be determined in a short time. Moreover, since it has a simple configuration mainly composed of the reference bar 2, the origin side reference pin 3, and the target point indexing drop pin 4, it can be implemented at low cost.

Easy to do based on.

  The origin-side reference pin 3 has a first engagement sleeve 10 and a reference pin member 11, and when the position of the origin-side reference pin 3 on the reference bar 2 is changed, the first engagement is first performed. It is possible to release the fixing of the sleeve 10 to the reference bar 2 and then move the sleeve 10 to a desired position in a desired direction, and then fix the first locking sleeve 10 to the reference bar 2.

  The target point indexing fall pin 4 has a predetermined length in the vertical direction, and has an inverted conical portion 4a for marking at the lower end, and is attached to the reference bar 2 so that its position in the length direction can be varied and the vertical position can be unchanged. The vertically locked second through-hole 14a of the second locking sleeve 14 is slidably inserted. Therefore, when the target point T is indexed on the floor surface or the like, if the target point indexing fall pin 4 is freely dropped by sliding the vertical through hole 14a of the second locking sleeve 14, it is used for marking the lower end portion. Since the inverted conical portion 4a marks an indentation on the floor surface, the indentation can be determined as the target point T.
