DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-4As shown, the utility model proposes an internal gear ring gear insertion application positioning tool, including a base 1, a positioning plate 3 and a positioning bolt 6 for positioning an internal gear ring workpiece 4, a connecting frame 2 is fixed on the upper end of the base 1, and the upper end of the connecting frame 2 is fixed to the positioning plate 3 through a fixing assembly 5, a lower convex ring 42 is arranged at the center position of the bottom of the internal gear ring workpiece 4, a center hole 31 matched with the lower convex ring 42 is opened at the center position of the positioning plate 3, a through hole 41 is arranged on the periphery of the internal gear ring workpiece 4, a threaded hole 32 is opened on the positioning plate 3 and at a position corresponding to the through hole 41, the bottom of the positioning bolt 6 passes through the through hole 41 and is threadedly connected in the threaded hole 32, a chip removal hole 21 is opened on the side wall of the connecting frame 2, and an arc plate 22 is fixed to the bottom of the connecting frame 2.

[0020] The fixing assembly 5 includes a sliding rod 51, a fixing block 52 and an insertion slot 53. The sliding rod 51 is slidably connected to the upper end of the connecting frame 2 and is equidistantly distributed. The fixing block 52 is fixed to the upper end of the sliding rod 51. The insertion slot 53 is provided at the bottom of the positioning plate 3 and is aligned with the fixing block 52. A sliding slot 54 is provided in the positioning plate 3 and above the insertion slot 53. An adapting slot 55 is provided on the side wall of the insertion slot 53 and is located at the bottom of the sliding slot 54. The diameter of the fixing block 52, the diameter of the insertion hole and the sliding slot are 54 has the same width, the diameter of the sliding rod 51 is smaller than the width of the fixed block 52, and is the same as the width of the adapting groove 55, a driving groove 56 is opened in the connecting frame 2 and at a position corresponding to the sliding rod 51, a sliding block 57 is slidably connected in the driving groove 56, the upper end of the sliding block 57 is fixed to the bottom of the sliding rod 51, a threaded rod 58 is rotatably connected in the driving groove 56, the threaded rod 58 passes through the sliding block 57 and is threadedly connected to the sliding block 57, and one outer end of the threaded rod 58 passes through the connecting frame 2 and is fixed with a knob 59.
