BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable part fixing jig for fixing an arm or the like which is a movable part when moving or carrying an articulated size measuring machine.

[0002]

2. Description of the Related Art When a multi-joint size measuring machine such as a three-dimensional size measuring machine is moved or transported, an arm or the like as a movable portion must be fixed in order to prevent damage to precision equipment.
At that time, each arm, the measuring terminal, and the like are individually fixed by using discrete components (fixing members, bolts, nuts, etc.).

[0003]

In the prior art, since the movable part fixing jig is composed of a large number of separated components, the number of components such as the fixing member and the bolts / nuts increases, and the movable part becomes larger. There has been a problem that it takes time to mount the fixing jig on the articulated dimension measuring machine, and it also takes a lot of time to remove the fixing jig after the movement or transportation.

The present invention has been made in view of the above problems of the prior art, and its object is to easily and surely fix in a short time and to remove it easily in a short time. An object of the present invention is to provide a movable part fixing jig for an articulated type dimension measuring machine.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a movable part fixing jig for fixing the movable part of an articulated dimension measuring machine, which has a rectangular shape composed of upper and lower members and side members. A frame is formed and fixed on the base of the articulated dimension measuring machine, a measurement terminal insertion hole is formed in the side member, a connection corner portion of the upper member and the side member, and the measurement terminal insertion hole. A cushioning material is provided on the inner peripheral surface and the peripheral portion, and a holding belt for fixing the movable portion to the upper member and the side member is provided.

[0006]

The movable part of the articulated dimension measuring machine is fixed and removed in a short time.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a movable part fixing jig according to the present invention, FIG. 2 is a side view of the same, FIG. 3 is a front view of FIG. 4, and FIG. It is a perspective view showing a fixed state.

The movable part fixing jig is a quadrangular frame-shaped fixing jig 5 consisting of an upper member 1, a lower member 2, and front and rear side members 3, 4, and two L-shaped fixing jigs 6, 6. It is composed of 7. Measuring instrument installation parts 8 and 9 are formed at the lower ends of the side members 3 and 4 of the frame-shaped fixing jig 5, and mounting holes 10 and 11 are provided in the measuring instrument installation parts 8 and 9, respectively.

A measurement terminal insertion hole 12 is formed in the vicinity of the measuring machine installation portion 8 of the side member 3, and a first arm holding belt 13 is mounted above the measurement terminal insertion hole 12. Further, a second arm holding belt 14 is attached near the middle portion of the upper member 1.

Buffer members 16 and 17 are provided on the inner peripheral surface and the peripheral portion of the connection corner portion 15 of the upper member 1 and the side member 3 and the measuring terminal insertion hole 12.

A reinforcing member 18 is arranged between the lower member 2 and the side member 3 to prevent distortion in the front-rear direction.

In the articulated type dimension measuring machine 20, a vertical drive shaft 22 is fixedly mounted on a base 21, and the front-back drive shaft 2 is attached to the vertical drive shaft 22.
3 is provided, the second arm 25 is provided at the tip of the front-rear drive shaft 23 via the second joint 24, and the first arm is provided at the tip of the second arm 25.
The first arm 27 is provided via the joint 26, and the first arm 2
The measurement terminal 29 is provided at the tip of the device 7 via the wrist 28.

When the tip of the measuring terminal 29 is brought into contact with the object to be measured, for example, the portion of the completed vehicle to be measured in a predetermined posture, it is provided on each drive shaft 22, 23, each joint 24, 26, wrist portion 28 and the like. The detection value of the position detector is calculated and the coordinate value with respect to the reference point, the distance between the two points, etc. are output.

A method of using the movable part fixing jig configured as described above in the articulated dimension measuring machine 20 will be described.

First, the front-rear drive shaft 23 that moves up and down the up-down drive shaft 22 is sandwiched between the two L-shaped fixing jigs 6 and 7, and is fixed to the up-down drive shaft 22 with bolts and nuts (not shown).

Next, the frame-shaped fixing jig 5 is placed on the base 21 of the articulated dimension measuring machine 20 with the lower member 2 facing down, and is attached to a mounting hole (not shown) formed in the base 21. Mounting hole 1
0, 11 are positioned, fixing bolts (not shown) are inserted into the mounting holes 10, 11 and tightened to fix the frame-shaped fixing jig 5 to the base 21.

Then, the second joint 24 is bent so that the second arm 25 follows the upper member 1, and the first joint 26 further bends so that the first arm 27 follows the side member 3, and the wrist portion 28.
Bending and inserting the measurement terminal 29 into the measurement terminal insertion hole 12 until the wrist portion 28 contacts the cushioning material 17.

Further, the first arm 27 is fixed to the side member 3 by the first arm holding belt 13, and the second arm 25 is fixed to the upper member 1 by the second arm holding belt 14 via the cushioning member 16.

As described above, the movable part of the articulated dimension measuring machine 20 is completely fixed by the movable part fixing jig composed of the frame-shaped fixing jig 5 and the two L-shaped fixing jigs 6 and 7. .

The first arm holding belt 13 and the second arm holding belt 13
The arm holding belt 14 may be a one-touch type that is easy to engage and disengage, but is not limited to this.

[0021]

As described above, according to the present invention, the fixing jig required for moving or carrying the articulated dimension measuring machine can be constructed with a small number of parts, which is easy and quick. Moreover, the movable part can be securely fixed. Further, since it can be easily removed in a short time, the setup time for the dimension measurement work can be shortened.
