Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gear positioning, and in particular relates to a gear tooth positioning auxiliary device. Background Art
[0002] A gear is a mechanical component with gears on its rim that continuously mesh to transmit motion and power. It is one of the most common and fundamental components in mechanical products. Each meshing projection on a gear, which meshes with a projection on another wheel to transmit force and motion, is called a tooth. Generally speaking, these projections are arranged radially. They are designed to contact similar projections on the mating gear, resulting in continuous meshing of the gears.
[0003] Chinese patent CN220591789U discloses a gear positioning device for a gear processing machine, which belongs to the field of gear positioning technology. A gear positioning device for a gear processing machine includes a gear base housing, a gear fixed driving member and a fixed gear head group, wherein a gear fixed driving member is rotatably installed inside the gear base housing, and at least three fixed gear head groups are installed on the gear fixed driving member; the upper end of the gear base housing is evenly provided with two radial through slideways corresponding to the number of fixed gear head groups, and each fixed gear head group is horizontally slidably connected to the corresponding through slideway two; the gear fixed driving member includes a driving turntable, a driven worm gear, a driving worm and a rotating handle, the driving turntable is rotatably installed in the gear base housing through a rotating shaft, and a driven worm gear is fixedly installed below the driving turntable, the driven worm gear is meshed with the driving worm, and the driving worm is rotatably installed inside the gear base housing, and either end of the driving worm rotates out of the gear base housing and is fixedly connected to the rotating handle.
[0004] At present, some equipment uses relatively smooth clamping plates to clamp and fix the gears. This method cannot clamp and fix the gears to the greatest extent. The gears may slide or shift during the processing. In the above documents, the fixed gear head group is a gear head adapted to the gear. The fixed gear head group can firmly limit the gear, but when replacing the gear head, it is necessary to first rotate the fixing nut to release the limit fixation of the gear head, and then rotate the angle of the gear head one by one, which is more troublesome.
[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

The outer surface of the column 401 is respectively fixedly connected with multiple groups of guide rails 605. The rotating column 601 and the protrusion 602 are slidably connected inside the guide rail 605.
[0040] The two groups of first sliding seats 403 and the two groups of second sliding seats 502 simultaneously drive the four groups of rotating columns 601 to move. The rotating columns 601 drive the protrusions 602 to slide along the guide rails 605.
