Description

Technical Field

[0001] The utility model relates to a tapping device for a flywheel locking piece. Background Art

[0002] The locking plate of the multi-stage flywheel is as follows Figure 6 As shown, the flange is obtained by stamping (see Figure 5 ), and finally tapping the inner hole of the flange. At present, tapping is done on automatic lathes, and its positioning is on the outer diameter of the flange. Since the flange is thin, a certain torque needs to be overcome when tapping after three-jaw positioning. The three-jaw positioning will cause deformation of the flange, thereby causing deformation of the inner hole, affecting the quality of the product. Utility Model Content

[0003] In view of the shortcomings existing in the above problems, the utility model provides a tapping device for a flywheel locking plate.

[0004] To achieve the above-mentioned purpose, the utility model provides a tapping device for a flywheel locking plate, comprising a turntable, through holes are evenly processed on the circumference of the turntable, a positioning plate is installed at the through hole, a positioning key groove is processed at the positioning inner hole of the positioning plate, a pressure block is installed on the right side of the turntable corresponding to the through hole, and a tap is installed on the bottom.

DETAILED DESCRIPTION

[0018] like Figure 1-3 As shown, the tapping device of a flywheel locking plate described in the utility model comprises a turntable 1, and the turntable 1 is rotated with an action gap through a cam divider 2. Through holes 11 are evenly processed on the circumference of the turntable 1, and a positioning plate 4 is installed at the through hole 11. A positioning key groove 42 is processed at the positioning inner hole 41 of the positioning plate 4, and the positioning key groove 42 matches the outer tongue 61 of the flywheel locking plate 6. A chamfer 43 is processed on the upper part of the positioning inner hole 41. A pressure block 5 is installed on the right side of the turntable 1 corresponding to the through hole 11, and a tap 3 is installed on the lower part. A pressure block key groove 51 is processed at the lower part of the pressure block 5, and the pressure block key groove 51 matches the outer tongue 61.

[0019] The device radially positions the flywheel locking plate by matching the positioning keyway with the outer tongue, thereby overcoming the huge torque generated during tapping and solving the deformation caused by the fixture during tapping on an ordinary lathe. The device is simple, the deformation of the flywheel locking plate after tapping is small, and the processing efficiency is high.

[0020] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0021] The locking plate of the multi-stage flywheel is as follows Figure 6 As shown, the function of the device is to tap and form the inner hole 63 of the flange 62.

[0022] During work, the untapped flywheel locking plate is placed in the positioning plate through chamfering, the positioning keyway matches the outer tongue, and the flywheel locking plate is radially positioned. When the flywheel locking plate is rotated to the bottom of the pressure block, the pressure block moves downward, and the pressure block keyway at the bottom of the pressure block presses the flywheel locking plate to axially position the flywheel locking plate. The tap passes through the through hole and taps upward. After completion, it is transferred to the next workstation for removal.

[0023] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
