Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, and more specifically to a mobile gear alignment mechanism and a gear grinding machine. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] Gears are widely used as mechanical elements that can continuously mesh to transmit motion and power. Gears need to be aligned during the processing process to obtain the positions of the tooth grooves and tooth tops of the gears to ensure that the grinding wheel can normally enter the grinding position and start working. The traditional fixed-structure gear alignment mechanism cannot be quickly and accurately adjusted to the appropriate gap with the workpiece after the product is replaced. It needs to be specially adjusted, which makes the operation inconvenient, and the repeatable positioning accuracy is difficult to ensure. The consistency of alignment is poor, and most traditional gear grinding machines are only equipped with one gear alignment mechanism. If the gear alignment mechanism is damaged while in use, it needs to be stopped for repair and cannot continue to work, which will affect the construction period to a certain extent. In view of this, the present application provides a mobile gear alignment mechanism and a gear grinding machine.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model.

[0008] As a further preferred embodiment, the cross-section of the slide groove is convex, and the convex slide groove has a limiting step surface. The support rod and the column are connected by at least one first screw, and the lower surface of the head of each first screw is in contact with the limiting step surface. A slider that slides in contact with the limiting step surface is also provided in the slide groove, and the slider cover is arranged on the outer surface of the screw head and the slider is fastened to the support rod by a first locking member.
