Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a machining tooling for ensuring the positional relationship between incomplete teeth and eccentric structures. Background Technology

[0002] Eccentric structures are a common type of mechanical structure, and eccentric machining is a common machining process; eccentric structures can be machined using eccentric tooling. For example... Figure 7 and Figure 8 The eccentric structure body 100 shown has a structural shaft 102. The left side of the eccentric structure body 100 is a small outer circle, and the right side has an incomplete external tooth 104, an eccentric outer circle, and an eccentric inner hole 105. There is a relief groove between the incomplete external tooth 104 and the eccentric outer circle. There is a structural pin hole 103 on the left end face of the incomplete external tooth 104. The center of the structural pin hole 103 is on a straight line connecting the center of the small outer circle and the center of a tooth groove of the incomplete external tooth. The line connecting the center of the structural pin hole 103 and the center of the small outer circle is at 180° with the line connecting the center of the eccentric inner hole 105 and the center of the small outer circle. The pin hole, the incomplete external tooth, and the eccentric inner hole 105 are all in a positional relationship. Under normal circumstances, the structural pin hole 103 can be machined first, and then the incomplete external tooth 104 and the eccentric inner hole 105 can be machined with the structural pin hole 103 as a positioning to ensure the positional relationship between the three. However, due to the special nature of this structure, if the incomplete outer tooth 104 is machined using the structural pin hole 103 for positioning, the right eccentric outer circle and the relief groove will be damaged. The tool feed direction can only be from left to right, and only gear shaping can be performed. Gear hobbing will also damage the right eccentric outer circle and the relief groove. Machining from left to right cannot be done using the structural pin hole 103 for positioning, nor can it be done using the eccentric inner hole 105 for positioning, resulting in a dilemma in machining.
