Abstract

PURPOSE:To dispense with the movement of a driving source of an X shaft and a Y shaft, and eliminate meandering creeping of driving wiring every time of the shaft movement by aggregating moving mechanisms of X and Y on a single plane. CONSTITUTION:In the Y directional movement of an installing stand 6, rotation of a Y shaft driving part 12 of a motor is performed by a Y shaft speed reduction part 11, a spline shaft 10, a Y shaft rotating slide gear 16 and a change in the perpendicular direction of a bevel gear 8. The X directional movement of the installing stand 6 is performed as follows. That is, when rotation of an X shaft driving part 13 of the motor rotates a screw part of an X shaft feeder 17 through an X shaft speed reduction part 14, the installing stand 6 supported with a Y bearing 3 and a Y shaft slide 5 to move according to rotation of an X, Y bearing part 15 and a cantilever preventive auxiliary X shaft 4, is moved in the X direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning X, Y and moving base structure for processing parts, assembling parts, cleaning parts and the like.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional two-stage stacking X, Y, moving base structure for machining parts.

As shown in the figure, there is a Y-axis base 22 supported on an X-axis slide 20 on an X-axis base 21, which are
Left and right movement is possible by the screw of the X-axis lever 17 and the X-axis drive unit 13 of the motor, and the deceleration unit of the X-axis gear. Also, the mounting base 6 of the positioning member slides on the Y-axis base on the upper Y-axis base. It is supported by a screw 5, a Y-axis occluder 7, a Y-axis deceleration unit, and a Y-axis drive unit 12 of the motor so that they can be moved left and right.

The problem with this structure is that since it has a two-tiered structure, it requires a lot of space in the height direction and tends to be weak in rigidity.

[0005]

When the X, Y moving mechanism is incorporated in a portion having a small space in the height direction, the conventional two-tiered X, Y moving mechanism has a height limitation and is in the same plane. It is to develop a mechanism that can perform the above X and Y operations.

[0006]

As shown in FIG. 1, a spline shaft 10 incorporating a Y-axis rotary slide gear as shown in FIG. Is converted to a right angle direction by a bevel gear (Y) 8 and is transmitted to the Y-axis drive 7, and when the X-axis drive 17 rotates and moves the X-axis drive 17, the Y-axis rotary slide gear 16 rotates the spline shaft. The mount 6 slides up and does not rotate, and the mount 6 can only move X. Although they are on the same plane as described above, the X and Y axes can be moved independently of each other.

[0007]

As shown in FIG. 1, when the mount 6 is moved in the Y direction, the rotation of the Y-axis drive unit 12 of the motor is such that the Y-axis speed reduction unit 11, the spline shaft 10, the Y-axis rotary slide gear 16, and the bevel gear (Y) 8 are provided. This is made possible by the Y-axis screw 7 screw by the right-angled direction conversion.

The movement of the mounting base 6 in the X direction is performed by rotating the X-axis drive section 13 of the motor through the X-axis speed reduction section 14 and rotating the screw section of the X-axis occluder 17. The mounting base 6 supported by the 15Y-axis slide 5 can be moved in the X direction. When the X-axis is moved, the Y-axis rotary slide gear 16 slides on the spline shaft so that the Y-axis is not moved.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a planar X, Y, moving base structure of the present invention.

As shown in FIG. 1, the X-axis drive unit 13, the X-axis speed reduction unit 14, the Y-axis drive unit 12, and the Y-axis of each motor have a structure in which the X-axis and Y-axis mechanisms are installed on the same line. The deceleration part 11 is integrated in one place, and the X-axis mechanism part is integrated by the Y-axis slide 5 to form a Y-axis bracket 3, a mounting base 6, X,
It moves the Y-axis hook portion 15, and constitutes a moving mechanism by simultaneous rotation of the X-axis driving portion 13, the X-axis lever 17 directly connected to the X-axis driving portion 13, the bevel gear 1, and the auxiliary X-axis 4 via the transmission shaft 18.

On the other hand, the Y-axis mechanism section moves the mount 6 supported by the Y-axis slide 5 to the left and right.
The spline shaft 10 as shown in FIG. 2 is directly connected to the shaft drive unit 12, and the Y-axis rotary slide gear 16 attached to the X- and Y-axis support unit 15 via the BB shaft support 9 is inserted into the shaft X.
The moving mechanism slides in the direction and rotates the Y-axis lever 7 via the bevel gear (Y) 8 when the spline shaft 10 rotates.

According to the above-described operation by the XY moving mechanism, when the mount 6 is moved in the Y direction, the rotation of the Y-axis drive unit 12 of the motor is the rotation of the Y-axis reduction unit 11, the spline shaft 10 and the Y-axis rotary slide gear 16. , By changing the bevel gear (Y) 8 in the direction of the right angle, using the screw of the Y-axis lever 7.

The movement of the mounting base 6 in the X direction is performed by rotating the X-axis drive unit 13 of the motor through the X-axis speed reduction unit 14 to rotate the screw portion of the X-axis occluder 17. 15 and the mounting base 6 supported by the Y-axis hook 3 and the Y-axis slide 5 that move by rotation of the cantilever auxiliary X-axis 4 can move in the X direction. When the X-axis is moved, the Y-axis rotary slide gear 16 slides on the spline shaft so that the Y-axis is not moved.

The feature of this structure described above is that the X and Y moving mechanisms are on the same line, so that they can be incorporated in a narrow space.

[0015]

【The invention's effect】

(1) Since the X and Y movement mechanisms are on the same line, it can be installed in a narrow space. (2) Mechanisms are integrated on a single plane. Moreover, since an auxiliary X bearing for cantilever prevention is provided, the mounting portion has good rigidity and slidability.

(3) Since the X-axis and Y-axis drive sources (motors) do not move due to the integration of the mechanisms, the drive wiring is not laid around every time the axis is moved.
