Abstract

The utility model relates to a clamp used for gear shaft machining. The shaft neck part of an existing gear shaft in an oil pump or in a speed reducer is so short that the tooth part of the gear shaft can not be rolling-cut by an ordinary apex or hoop on a gear hobbing machine. In addition, the usage of an inner taper hole apex has the disadvantages that workpiece positioning accuracy is poor, clamping force is small and replacement is troublesome. The clamp used for gear shaft machining comprises an upper apex and a lower apex, wherein the upper apex and the lower apex are used for positioning a gear shaft, two half-jackets with positions adjustable used for clamping the gear shaft are arranged outside the lower apex, a bolt and a nut are arranged outside the two half-jackets respectively, a base is arranged below the half-jackets and is installed on a working platform of a machine tool, a taper hole used for accommodating a tapered shank of the lower apex is formed in the base, the axis of the taper hole is perpendicular to the plane of the base, a tensioning bolt is arranged at the lower end of the bottom of the taper hole, and a gasket is arranged between the tensioning bolt and the base. The clamp used for gear shaft machining is simple in structure, scientific in design, easy to manufacture, high in positioning accuracy, big in clamping force, and fast in replacement.

Description

Gear shaft processing clamp
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of gear shaft processing clamp.
Background technology
Gear shaft in the existing oil pump and the gear shaft neck part in the decelerator are too short, can't use common top, such gear shaft tooth section of clip rolling cut on gear-hobbing machine.In addition, use internal taper hole top, exist the workpiece positioning accuracy poor, chucking power is little, changes the shortcomings such as trouble.
Summary of the invention
The technical problems to be solved in the utility model is the defects that how to overcome prior art, and a kind of gear shaft processing clamp is provided, and this gear shaft processing clamp positioning accuracy 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 the positioning tooth wheel shaft, the lower top outside is provided with two and half chucks for the adjustable position of fastening teeth wheel shaft, two and the half chucks outside is 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 accuracy is high, and chucking power is large, changes quick.
As optimization, base is provided with the taper hole for conical grip top under placing, and the taper hole axis is vertical with base plane, and lower end, taper hole bottom is provided with turnbuckle, is provided with packing ring between turnbuckle and the base.
The utility model gear shaft processing clamp, simple in structure, design science is made easily, and positioning accuracy is high, and chucking power is large, changes fast, has preferably actual application value and promotional value.
Description of drawings
Below in conjunction with accompanying drawing this gear shaft processing clamp is described further:
Fig. 1 is the structural representation of gear shaft;
