[Problems to be solved by the device]

However, according to the conventional slide adjusting unit configured as described above, since the unit 6 in the X direction and the unit 12 in the Y direction are stacked in two stages, the height is increased and the space for mounting is increased. There was a problem of getting bigger.

In addition, the number of constituent parts is increased and the cost is increased.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a small-sized and inexpensive slide adjusting unit capable of finely adjusting the positions of two orthogonal axes.

[Means for solving the problem]

According to the present invention, in order to achieve the above object, a flat plate-shaped slide plate having a cross-shaped protrusion and a groove for holding the slide plate and slidingly fitting the protrusion are formed in a cross shape. In a slide adjusting unit including a pair of guide brackets facing each other, first and second slide adjusting units are provided.
On the surfaces of the pair of guide brackets 22, 23 facing the slide plate 21, cross-shaped groove portions 22a, 22b into which the projections 21a, 21b of the slide plate 21 orthogonal to each other are fitted, respectively. 22 and the cross-shaped groove portions 23a and 23b are also formed in the second guide bracket 23 so that the width of the vertical protruding portion 21a and the width of the vertical groove portion 22a of the first guide bracket 22 are equal. Then
In addition, the width of the lateral groove portion 22b into which the lateral protrusion portion 21b is fitted is increased by a slide amount, and the width of the lateral protrusion portion 21b and the lateral groove portion 23b of the second guide bracket 23 are formed. And the width of the vertical groove 23a into which the vertical protrusion 21a is fitted is increased by the amount of slide, and the vertical fine adjustment screw attached to the first guide bracket 22 is provided. 32 is screwed onto the vertical protrusion 21a of the slide plate 21, and the second guide bracket 2
Similarly, the horizontal fine adjustment screw 33 attached to 3 is screwed to the horizontal protrusion 21b, and the slide plate 21 is provided with a long hole 26 through which the guide pin 24 penetrates in the vertical direction.
Similarly, a through hole 27 formed in the second guide bracket 23
The inner diameter of the guide pin 24 is larger than the outer diameter of the guide pin 24 by the amount of the slide, and the pair of guide brackets 22 and 23 are integrated by the guide pin 24 via the slide plate 21 so as to be finely movable in two directions orthogonal to each other. It has been fastened.

[Action]

According to the above configuration, since the slide plate is held between the pair of guide brackets having the cross-shaped groove portion, when the slide plate 21 slides in the vertical direction by the fine adjustment screw 32, the first guide bracket
When 22 does not move, it moves integrally while being fitted with the second guide bracket 23 using it as a guide, and when it is slid by the fine adjustment screw 33 in the lateral direction orthogonal to this,
The slide plate 21 does not move while being fitted integrally with the first guide bracket 22, and only the second guide bracket 23 moves using the slide plate 21 as a guide.
The long hole 26 is provided in the vertical direction in the second guide bracket 23.
Since the through hole 27 is formed so that the inner diameter is larger than the outer diameter of the guide pin 24 by the amount of the slide, the guide pin 24 necessary for integrally fastening when slightly moving in two directions does not touch any of them. Therefore, the vertical projections 21a of the flat slide plate 21 do not interfere with each other and
And the horizontal protrusion 21b to the vertical and horizontal fine adjustment screws 32, 33.
Since it is screwed on, it is thinner and smaller than the conventional slide adjustment unit, and the pair of guide brackets can be finely adjusted in two orthogonal directions via the slide plate, and the number of parts is reduced and the cost is reduced. .

〔Example〕

Hereinafter, an embodiment of a slide adjusting unit according to the present invention will be described with reference to the drawings.

1 to 4 show one embodiment of the present invention. In the figure, a pair of guide brackets 22 and 23 are provided on both sides of a slide plate 21 formed in a cross shape,
On the surfaces of the guide brackets 22 and 23 facing the slide plate 21, the groove portions 22a and 22b into which the protrusions 21a and 21b orthogonal to the slide plate 21 are fitted respectively, and
23a and 23b are formed in a cross shape. And the protrusions 21a, 2
When the width of 1b is A and B, respectively, the width of the groove portion 22a of the guide bracket 22 into which the protruding portion 21a is fitted is equal to A, and the fitting is fitted. The direction of the groove 22a is defined as the X direction.

On the other hand, the width of the groove portion 22b of the guide bracket 22 into which the projecting portion 21b is fitted is the sum of the B and the slide amount β of the slide plate 21 in the X direction, and the guide bracket 22 is attached to the slide plate 21. On the other hand, it can slide accurately only in the X direction.

Similarly, the width of the groove portion 23b of the guide bracket 23 is equal to B, and they are fitted to each other. The direction of the groove 23b is the Y direction. The width of the groove 23a is the sum of the above A and the slide amount α of the slide plate 21 in the Y direction, so that the guide bracket 23 can slide accurately with respect to the slide plate 21 only in the Y direction. ing.

The guide brackets 22 and 23 are the slide plates 21.
Is held by a guide pin 24 and a set screw 25 so that the X direction and the Y direction are perpendicular to each other. The guide pin 24 and the set screw 25 are fixed to the guide bracket 22. At this time, since the slide plate 21 moves in the X direction with respect to the guide pin 24, the hole 26 formed in the slide plate 21 through which the guide pin 24 penetrates is a long hole that is long in the X direction.

Also, the guide bracket 23 is
Since it moves in the X and Y directions, the hole 27 formed in the guide bracket 23 through which the guide pin 24 penetrates is larger in the X and Y directions, and its inner diameter is larger than the outer diameter of the guide pin 24 by the sliding amount. There is. In addition, guide brackets 22,23
Since the other units 28 and 29 are attached to the outer surfaces of the respective guides, the guide pins 24 of the guide brackets 22 and 23,
At the mounting portion of the set screw 25, a step portion is formed which is lower by the flange thickness of each of the guide pin 24 and the set screw 25. Further, the guide brackets 22 and 23 are provided with X direction fine adjustment screws 32 and Y direction fine adjustment screws 33 via brackets 30 and 31, respectively, as in the conventional example.

Next, the operation of this embodiment will be described. When adjusting the position in the X-axis direction, when the X-direction fine adjustment screw 32 is rotated, the slide plate screwed to the tip of the screw 32 is rotated.
21 slides in the X direction. At this time, since the projection 21a in the X direction of the slide plate 21 and the groove 22a in the X direction of the guide bracket 22 are fitted and fitted to each other, the slide plate 21 slides accurately without moving in the Y direction.

Similarly, when the Y direction fine adjustment screw 33 is rotated, the guide bracket 23 slides in the Y direction relative to the slide plate 21. That is, by rotating the screws 32 and 33, the guide bracket 23 moves relative to the guide bracket 22 in the X and Y biaxial directions.

Therefore, by attaching the units 28 and 29 to the guide brackets 22 and 23, respectively, it is possible to finely adjust the relative position of the unit 29 with respect to the unit 28 in the biaxial X and Y directions.

According to the present embodiment, since the slide adjusting unit is configured by sandwiching the cross-shaped slide plate 21 with the pair of guide brackets 22 and 23, the fine adjustment is more accurate than the conventional slide adjusting unit. In addition, it can be made thin and small, the number of parts can be reduced, and the cost can be reduced.

Therefore, it can be used for various detector mounting parts, jig parts, various machining tool mounting parts, and the like.

[Effect of device]

As described above, according to the slide adjusting unit of the present invention, since the slide plate is held by the guide bracket having the pair of cross-shaped grooves, the flat slide plate 21 slides in the vertical direction. In this case, the first guide bracket 22 does not move, and the first guide bracket 22 moves as a guide while integrally moving with the second guide bracket 23, and when sliding in the lateral direction orthogonal to this, the slide plate 21 Does not move while being fitted integrally with the first guide bracket 22, and only the second guide bracket 23 moves using it as a guide, and the movement position is limited by the pair of guide brackets 22, 23. Fine movement adjustment work in the two axis directions can be performed extremely easily. Moreover, since the elongated hole 26 is provided in the slide plate 21 in the longitudinal direction and the through hole 27 is formed in the second guide bracket 23 so that the inner diameter thereof is larger than the outer diameter of the guide pin 24 by the amount of the slide, the pair of guide plates 22 When 23 and 23 are finely moved in the directions of two axes which are orthogonal to each other, neither of them touches the guide pin 24, which is necessary for fastening together, so that the pair of guide plates 22 and 23 interfere with each other. There is no need for smooth fine movement, and the vertical and horizontal projections 21a and 21b of the flat slide plate 21 are screwed with vertical and horizontal fine adjustment screws 32 and 33.
Since the two fine adjustment screws 32 and 33 can be mounted on almost the same plane, it is possible to make the device thinner and smaller, and to perform precise mutual adjustments in two directions, and to widen the usable range. The number of parts is reduced and the cost can be reduced.
