The utility model provides a moving mechanism, which comprises a base 100, a rack 200 and a gear 300, wherein the rack 200 and the gear 300 are both arranged on the base 100, and the rack 200 is in meshed connection with the gear 300; further comprises:

a pressing block 400, the pressing block 400 being mounted on the base 100; the pressing block 400 is disposed at a side of the rack 200 facing away from the tooth surface and is closely attached to the rack 200.

In practical use, after the rack 200 is engaged with the gear 300, when the gear 300 is driven to move, the rack 200 moves along the radial direction of the gear 300 due to the influence of the engagement precision, so that the movement precision of the rack 200 is reduced.

In this embodiment, the pressing block 400 is disposed on the side of the rack 200 facing away from the tooth surface to apply pressure to the rack 200 so as to limit the movement of the rack 200 along the radial direction of the gear 300, thereby realizing a limiting effect on the rack 200 when the rack 200 moves, and ensuring that the movement accuracy of the rack 200 is not reduced.

Further, the rack 200 may be a helical rack, a straight rack, etc., and the gear 300 is a helical gear, a straight gear, etc.

Further, the pressing block 400 may be fixedly mounted on the base 100 or movably mounted on the base 100, where the movable mounting means that the position of the pressing block 400 on the base 100 is adjustable.

In some embodiments, the side of the rack 200 facing away from the tooth surface is in close contact with one of the compression blocks 400, and the center line of connection between the gear 300 engaged by the same rack 200 and the adjacent compression block 400 is not perpendicular to the corresponding rack 200.

In this embodiment, the center line between the pressing block 400 and the gear 300 refers to the line between the center of the pressing block 400 and the center of the gear 300. The fact that the central connecting line between the pressing block 400 and the gear 300 is not perpendicular to the corresponding rack 200 means that the gear 300 and the pressing block 400 are arranged in a staggered manner.

The offset arrangement of the gear 300 and the pressing block 400 can also play a certain limiting role on the rack 200, so that the movement accuracy of the rack 200 can also be ensured.

The present embodiment includes the following cases:

In this embodiment, the center line between the pressing block 400 and the gear 300 refers to the line between the center of the pressing block 400 and the center of the gear 300. The fact that the center line between the pressing block 400 and the gear 300 is perpendicular to the corresponding rack 200 means that the gear 300 is aligned with the pressing block 400.

The gear 300 and the pressing block 400 are aligned, so that the gap between the engaged positions of the aligned gear 300 and the corresponding rack 200 can be controlled most effectively, and the movement accuracy of the rack 200 is highest.

The present embodiment includes the following cases:

1. the racks 200 are only meshed with one gear 300, and the gear 300 meshed with the corresponding racks 200 is aligned with the tightly attached compression block 400;

2. the rack 200 is engaged with the plurality of gears 300, and one gear 300 is aligned with the tightly-attached pressing block 400 in the gears 300 engaged with the corresponding rack 200.

In some embodiments, the plurality of compression blocks 400 tightly attached to the same rack 200 are not symmetrically distributed; in this case, the force applied to each position of the rack 200 is not uniform, and the movement of the rack 200 may be hindered.

In certain preferred embodiments, the rack 200 is engaged with one of the gears 300, and all of the compression blocks 400 to which the same rack 200 is attached are symmetrically distributed about a first perpendicular from the center of the engaged gear 300 to the longitudinal axis of the corresponding rack 200.

In this embodiment, all the pressing blocks 400 closely attached to the same rack 200 are symmetrically distributed about the first perpendicular line, so that the uniform stress at each position of the rack 200 can be ensured, and smooth movement of the rack 200 can be ensured.

The present embodiment includes the following cases:

1. one of the pressing blocks 400 closely attached to the corresponding rack 200 is provided with a pressing block 400 aligned with the meshed gear 300;

2. all the pressing blocks 400 to which the corresponding racks 200 are closely attached are arranged in a staggered manner with the engaged gear 300.

In this embodiment, all the gears 300 engaged with the same rack 200 and all the pressing blocks 400 tightly attached to the same rack 200 are symmetrically distributed about the second perpendicular line, so that the uniform stress at each position of the rack 200 can be ensured, and smooth movement of the rack 200 can be ensured.

The present embodiment includes the following cases:

1. each pressing block 400 which is tightly attached to the corresponding rack 200 is correspondingly arranged in alignment with one meshed gear 300;

2. of all the pressing blocks 400 to which the corresponding racks 200 are closely attached, at least one pressing block 400 is disposed in alignment with the engaged gear 300.

3. All the pressing blocks 400 closely attached to the corresponding racks 200 are arranged in a staggered manner with all the gears 300 engaged.

In some embodiments, at least two racks 200 are included, each rack 200 is provided with a supporting arm 500, and all racks 200 are driven by the corresponding engaged gear 300 to drive all supporting arms 500 to approach or separate from the same target (so as to clamp or unclamp the target, but not limited to clamping the target, and can be a supporting target).

In this embodiment, the gears 300 engaged with all the racks 200 may be the same gears 300 or different gears, for example, two racks 200 are provided, both racks 200 are engaged with the same gear 300, and the rotation of the driving gear 300 can control the movement of the two racks 200, so as to control the holding arms 500 to approach or separate from each other. Because each rack 200 is limited by the tightly attached compression block 400, the moving precision of the supporting arm 500 can be ensured, and the requirement of the allowed distance between the supporting arm 500 and the pipe material during the laser pipe cutting can be further met.

In some embodiments, the compression block 400 is in the shape of a sphere or cylinder.

In this embodiment, the compression block 400 is a sphere or a cylinder, which can reduce the contact friction with the rack 200, avoid the difficulty in moving the rack 200 due to excessive friction, but not affect the limiting effect on the rack 200, and still ensure the movement accuracy of the rack 200.

In some embodiments, the compression block 400 is rotatably disposed on the base 100 and is in rolling connection with the rack 200, and the compression block 400 is capable of rolling relative to the rack 200 along the length of the rack 200.

In this embodiment, the compression block 400 is configured to roll, so that the friction between the compression block 400 and the rack 200 is changed from sliding friction to rolling friction, thereby reducing wear of the rack 200 and the compression block 400, effectively prolonging the overall service life, and ensuring that the rack 200 can still move with high precision after repeated use.

The utility model also provides a laser pipe cutting machine, which comprises the moving mechanism in the embodiment.
