Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.
The following describes a gear shaft hobbing fixture according to some embodiments of the present utility model with reference to the accompanying drawings.
Examples
Referring to fig. 1-3, the gear shaft hobbing fixture provided by the utility model comprises a main body mechanism 100 and a clamping mechanism 200, wherein the main body mechanism 100 comprises an outer sleeve 110, an adjusting groove 120 arranged on the side edge of the middle part of the outer sleeve 110, a straight rack 150 arranged at the bottom of the adjusting groove 120, a large gear 140 meshed with the straight rack 150, a small gear 160 coaxially connected with the large gear 140, a retaining nut 180 in threaded connection with the outer end shaft of the large gear 140, and a clamping groove 170 arranged in the middle part of the outer sleeve 110, a fixed sliding groove 130 is arranged in the middle part of the adjusting groove 120, the outer end of the large gear 140 is slidably connected in the fixed sliding groove 130, the clamping mechanism 200 comprises a movable clamping plate 210 meshed with the small gear 160, a bottom plate 220 fixed at the bottom of the movable clamping plate 210, a fixed clamping plate 230 fixed at one side of the outer sleeve 110 far away from the movable clamping plate 210, a sliding groove 240 is arranged in the middle part of the movable clamping plate 210, the middle part of the movable clamping plate 210 is arc-shaped, the fixed clamping plate 230 is also arc-shaped, the sliding groove 240 is slidably connected with a sliding block 250, and the sliding block 250 is transversely provided with a transverse groove 260.
