Abstract
本发明涉及一种齿轮轴加工夹具。现有的油泵中的齿轮轴和减速器中的齿轮轴轴颈部分过短，在滚齿机上无法使用普通的顶尖、卡箍滚切该类齿轮轴齿部。另外，使用内锥孔顶尖，存在工件定位精度差，夹持力小，更换麻烦等缺点。为此，本齿轮轴加工夹具，包括用于定位齿轮轴的上顶尖和下顶尖，下顶尖外侧设有用于夹紧齿轮轴的可调整位置的两个半夹套，两个半夹套外侧设有螺栓和螺母，半夹套下方设有底座，底座安装在机床的工作台上；底座上设有用于放置下顶尖的锥形柄的锥孔，锥孔轴线与底座平面垂直，锥孔底部下端设有拉紧螺栓，拉紧螺栓和底座之间设有垫圈。本发明结构简单，设计科学，容易制造，定位精度高，夹持力大，更换快捷。
The invention relates to a gear shaft processing fixture. The gear shaft in the existing oil pump and the gear shaft journal in the reducer are too short, and it is impossible to use common tops and hoops on the gear hobbing machine to hob and cut the gear shaft teeth of this type. In addition, using the tip of the inner tapered hole has disadvantages such as poor positioning accuracy of the workpiece, small clamping force, and troublesome replacement. For this reason, the gear shaft processing fixture includes an upper top and a lower top for positioning the gear shaft, two half jackets for clamping the adjustable position of the gear shaft are arranged on the outside of the lower top, and two half jackets are provided outside the two half jackets. There are bolts and nuts, there is a base under the half-jacket, and the base is installed on the workbench of the machine tool; the base is provided with a taper hole for placing the tapered shank of the lower tip, the axis of the taper hole is perpendicular to the plane of the base, and the bottom of the taper hole is at the lower end Tension bolts are provided, and washers are arranged between the tension bolts and the base. The invention has the advantages of simple structure, scientific design, easy manufacture, high positioning accuracy, large clamping force and quick replacement.
Description
Technical field
The present invention relates to a kind of fixture, particularly a kind of gear shaft processing clamp.
Background technology
Gear shaft in existing oil pump and the gear shaft neck part in decelerator are too short, cannot use common top, such gear shaft tooth portion of clip rolling cut on gear-hobbing machine.In addition, use internal taper hole top, exist workpiece positioning precision poor, chucking power is little, changes the shortcomings such as trouble.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect that how to overcome prior art, and a kind of gear shaft processing clamp is provided, and this gear shaft processing clamp positioning precision is high, and chucking power is large, changes quick.
For solving the problems of the technologies described above, this gear shaft processing clamp, comprise upper top and lower top for positioning tooth wheel shaft, lower top outside is provided with two and half chucks for the adjustable position of fastening teeth wheel shaft, two and half chuck outsides are provided with screw bolt and nut, half chuck below is provided with base, and floor installation is on the workbench of lathe.
So design, positioning precision is high, and chucking power is large, changes quick.
As optimization, base is provided with for placing the taper hole of lower top conical grip, and taper hole axis is vertical with base plane, and lower end, taper hole bottom is provided with turnbuckle, between turnbuckle and base, is provided with packing ring.
Gear shaft processing clamp of the present invention, simple in structure, design science, easily manufactures, and positioning precision is high, and chucking power is large, changes fast, has good actual application value and promotional value.
