Abstract

The invention relates to a gear shaft processing fixture. Shaft neck parts of a gear shaft in an existing oil pump and a gear shaft in a speed reducer are too short, so that a general tip and a hoop cannot be used for hobbing gear parts of the gear shafts on a gear hobbing machine. In addition, the application of an inner conical hole tip has such defects as weak workpiece positioning preciseness, low clamping force and troublesome replacement. The gear shaft processing fixture comprises an upper tip and a lower tip for positioning a gear shaft; two half jackets for clamping the gear shaft and with adjustable positions are arranged at the outer side of the lower tip; a bolt and a nut are arranged at the outer sides of the two half jackets; a base is arranged below the half sleeves, and is mounted on a working table of a machine tool; a conical hole for accommodating a conical handle of the lower tip is formed in the base; the axial line of the conical hole is perpendicular to the plane of the base; a tension bolt is arranged at the lower end of the bottom of the conical hole; and a washer is arranged between the tension bolt and the base. The gear shaft processing fixture has the advantages of simple structure, scientific design, easy production, high positioning preciseness, high clamping force and quick replacement.

Description

Gear shaft processing clamp
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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this gear shaft processing clamp is described further:
Fig. 1 is the structural representation of gear shaft;
Fig. 2 is the structural representation of this gear shaft processing clamp.
In figure: 1 for workbench, 2 for turnbuckle, 3 for bolt, 4 for lower top, 5 for gear shaft, 6 for upper top, 7 be that half chuck, 8 is for nut, 9 is for base, 10 is for packing ring.
The specific embodiment
For making object of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
As shown in Figure 2, this gear shaft processing clamp, comprise for upper top 6 and lower top 4 of positioning tooth wheel shaft 5, lower top 4 outsides are provided with two and half chucks 7 for the adjustable position of fastening teeth wheel shaft 5, two and half chuck 7 outsides are provided with bolt 3 and nut 8, half chuck 7 belows are provided with base 9, and base 9 is arranged on the workbench 1 of lathe.
Base 9 is provided with for placing the taper hole of lower top 4 conical grip, and taper hole axis is vertical with base 9 planes, and lower end, taper hole bottom is provided with turnbuckle 2, between turnbuckle 2 and base 9, is provided with packing ring 10.
The taper hole of base 9 is chosen Mohs No. 4.During use, screw nut 8, two halves chuck 7 closes up can fastening teeth wheel shaft 5.Be applicable to all kinds of few number of teeth below m=6, the tooth Profile Machining of minor axis neck gear shaft.
The above-mentioned specific embodiment is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to product form and the style of the above-mentioned specific embodiment; anyly meet the gear shaft processing clamp of the claims in the present invention book and suitable variation or the modification that any person of an ordinary skill in the technical field does it, all should fall into scope of patent protection of the present invention.
