The slide holder 7 is fixed.

On the upper surface of the slide holder 7, a plate-shaped work support plate having a front notch 9F on the front side (right side in FIG. 1) and a rear notch 9R on the rear side (left side in FIG. 1). 1
1 is provided. An overall L-shaped holder 13 is attached to the lower surface of the rear internal space 5R of the slide holder 7, and a plate-like slide holder 15 is attached to the lower surface of the front internal space 5F.

A first slide 17 is supported between the slide holder 15 and the work support plate 11 in the front inner space 5F of the slide holder 7 so as to be movable in the front-rear direction (the left-right direction in FIG. 1). A second slide 19 is provided between the holder 13 and the work support plate 11 in the rear inner space 5R so as to be movable in the front-rear direction.

A screw hole 21 is provided in the center partition 3 which is located at the center of the slide holder 7 and is integral with the slide holder 15, and the through hole 2 which passes through the center of the first slide 17 is provided.
A stop position adjusting screw 25 is provided as a first screw member that is screwed into the screw hole 21 through the screw hole 3. The through hole 23 has a thick front half 23A and a thin rear half 23B (see FIGS. 2A and 2B), and the head 27 of the stop position adjusting screw 25 is locked by this step. .

Also, the central partition wall 3 and the first slide 17
A spring 29 as a first elastic member is provided between the first slide 17 and the first slide 17 by the repulsive force adjusted by the stop position adjusting screw 25.

A reference clamp jaw 31F is provided above the front end of the first slide 17 so as to extend upward, project from the front notch 9F of the work support plate 11, and clamp the work W. This reference side clamp jaw 3
The position of 1F corresponds to the optical component W of the maximum size.

Accordingly, by rotating the stop position adjusting screw 25 to move it back and forth relatively to the central partition wall 3, the forward repulsive force of the spring 29 can be adjusted, and the first slide 17 can be adjusted by the stop screw 33.
Can be fixed. When the stop position adjusting screw 25 is loosened and pulled out of the slide holder 7, the first slide 17 and the spring 29 can be easily replaced.

On the other hand, a blind hole 35 is formed in the rear portion at the center of the cross section of the second slide 19, and the blind hole 35 is opened in the rear end face. Have been. The front end is pressed against the spring 37 to be urged rearward, and the rear end is projected rearward from the second slide 19 and screwed into the screw hole 39 provided in the slide holder 7. An adjusting member 41 is provided inside the blind hole 35.

Accordingly, by rotating the pressure adjusting member 41, the member is moved relatively back and forth with respect to the slide holder 7 and the repulsive force of the spring 37 rearward (ie,
The resilience for urging the second slide 19 forward) can be adjusted, and the pressing adjustment member 41 is loosened to allow the slide holder 7 to move.
, The spring 37 can be replaced.

On the upper rear end of the second slide 19,
A movable clamp jaw 31 that extends upward, projects from the rear notch 9R of the work support plate 11, and clamps the work W.
M is provided. On the other hand, a flange 43 projecting downward from the slide holder 7 is provided below the rear end of the second slide 19.

An air cylinder 45 is mounted on the lower surface of the holder 13 as an example of an unclamping moving means.
7 is attached to the flange 43 described above.

Therefore, at the time of unclamping, the second slide 19 can be moved rearward by the air cylinder 45. At the time of clamping, the air cylinder 45 is deactivated, so that the resilient force of the spring 37 causes the pressing adjustment member 41 to move. The second slide 19 is biased forward through the second slide 19.

With the above configuration, when clamping the optical component W, first, the second slide 19 is moved by the air cylinder 45.
Is moved backward against the spring 37, the movable clamp jaw 31M is separated from the reference clamp jaw 31F, and the optical component W is set between the movable clamp jaw 31M and the reference clamp jaw 31F.
Turn 5 off. The second slide 19 is a pressing adjustment member 41
Is moved forward by the repulsive force of the spring 37, and clamps the optical component W between the movable clamp jaw 31F and the reference clamp jaw 31M.

When the optical component W is unclamped, the second slide 19 is moved backward by the air cylinder 45 to unclamp the optical component W.

Although the case where the first slide 17 for clamping the optical component W having the maximum width is used has been described above, when the optical component W having the intermediate size is clamped, the first slide 17 for the maximum width is used. The slide 17 is replaced with a first slide 49 for the intermediate size as shown in FIG. 3 to clamp the optical component W of the intermediate size. Since other structures are the same as those of the clamp device 1 shown in FIGS. 1 and 2 described above, the same portions are denoted by the same reference numerals, and redundant description will be omitted.

Similarly, when clamping the optical component W of the minimum size, the optical component W of the minimum size is replaced by the first slide 51 for the optical component of the minimum size as shown in FIG. Clamp W.

From the above results, the optical components W of various sizes can be clamped with a predetermined pressing force by replacing a small number of components. Since the clamping force is obtained by the repulsive force of the spring 37, the optical component W
Can be prevented from being damaged due to an excessive force acting on the member.

It should be noted that the present invention is not limited to the above-described embodiment of the present invention, but by making appropriate changes,
It can be implemented in other aspects.
