Abstract
The utility model discloses a clamp special for inner hole single-key gear machining. The clamp comprises a female sleeve and a tool. The female sleeve comprises a machine tool connecting portion and a tool connecting portion, wherein the machine tool connecting portion and the tool connecting portion are integrated. A first through hole is formed in the center of the female sleeve, and the tool comprises a gear supporting portion, a connecting disc and a male portion, wherein the gear supporting portion, the connecting disc and the male portion are integrated. A second through hole concentric with the first through hole is formed in the center of the tool. The male portion is matched with the first through hole. The tool connecting portion is fixedly connected with the connecting disc through a first bolt, and a central spindle is in clearance fit with the interior of the second through hole. A single key is arranged on the outer surface of the central spindle. A third through hole concentric with the second through hole is formed in the center of the central spindle. The clamp special for inner hole single-key gear machining is simple in structure and convenient to use, gear inner hole key grooves with different types and sizes can be machined by using the central spindles matched with the gear inner hole key grooves without replacing the whole tool, so that clamping efficiency is high, the installation precision of the clamp and a machine tool does not need to be corrected repeatedly, and machining precision and percent of pass of gears are improved.
Description
Technical field
The utility model relates to a kind of fixture, particularly relates to a kind of for processing the fixture of endoporus singly-bound gear.
Background technology
The endoporus of gear is connected or spline joint with axle singly-bound, or interference fit, with transfer motion power.In the process of gear, need, by clamping blanking inner hole, it to be fixed, then its appearance profile of milling.For singly-bound bore, may relate to the inner hole key slot of Multiple Type size, need multiple corresponding special fixture could clamp gear blank, therefore the versatility of fixture is poor, and clamp-replacing efficiency is low, and the qualification rate of gear is low.
Therefore those skilled in the art are devoted to develop the endoporus singly-bound Gear Processing special fixture that a kind of versatility is higher.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the endoporus singly-bound Gear Processing special fixture that a kind of versatility is higher.
For achieving the above object, the utility model provides a kind of endoporus singly-bound Gear Processing special fixture, comprises mother set and frock; Described mother set comprises lathe connecting portion and the frock connecting portion of one; The center of described mother set is provided with the first through hole;
Described frock comprises gear support portion, terminal pad and the public portion of one; The center of described frock is provided with second through hole concentric with described the first through hole; Described public portion coordinates with described the first through hole; Described frock connecting portion is fixedly connected with by the first bolt with described terminal pad;
Described the second through hole internal clearance is combined with mandrel; The outer surface of mandrel is provided with singly-bound; The center of described mandrel is provided with the third through-hole concentric with described the second through hole.
Be connected with lathe for ease of mother set, described lathe connecting portion is the frustum of a cone of relatively described frock connecting portion projection.
For preventing that mandrel and frock from producing axially-movable, described mandrel and frock have been disposed radially the second bolt.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, for the gear inner hole key slot of different model size, only need to use the mandrel matching, and need not change whole frock, therefore clamping efficiency is high, also without the installation accuracy of repeatedly proofreading fixture and lathe, thereby has improved machining accuracy and the qualification rate of gear.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of endoporus singly-bound Gear Processing special fixture, comprises mother set 1 and frock 2.Mother set 1 comprises lathe connecting portion 1a and the frock connecting portion 1b of one, and the center of mother set 1 is provided with the first through hole 1c.
Frock 2 comprises the 2a of gear support portion, terminal pad 2b and the public 2c of portion of one, and the center of frock 2 is provided with the second through hole 2d concentric with the first through hole 1c, and the public 2c of portion coordinates with the first through hole 1c.Frock connecting portion 1b is fixedly connected with by the first bolt 4 with terminal pad 2b.
The second through hole 2d internal clearance is combined with mandrel 3, and the outer surface of mandrel 3 is provided with singly-bound 3a, and the center of mandrel 3 is provided with the third through-hole 3b concentric with the second through hole 2d.
When sectional fixture, first make the frustum of a cone of mother set 1 coordinate with lathe (not shown), thereby make mother set 1 can bear certain axial and radial load.Then make frock 2 coordinate with mother set 1, and fix by the first bolt, finally make mandrel 3 coordinate with frock 2, and adopt the second bolt 5 to locate.Gripping sleeve 6 coordinates with telescopic screw rod (not shown) on lathe.
As shown in Figure 4, in mandrel 3, be combined with gripping sleeve 6.As shown in Figures 2 and 3, be provided with fourth hole 6a in gripping sleeve 6, fourth hole 6a is provided with internal thread 6b near the tail end of mother set 1.The overhanging end 6c of gripping sleeve 6 is four uniform cantilever designs, and the end of cantilever forms cone structure jointly.
When machining gears, end has the gripping sleeve 6 of spring function through bore, the keyway of bore is coordinated with the singly-bound of mandrel, then screw rod (not shown) retraction, drive gripping sleeve 6 axially-movables, thereby the laminating of the conical end portion that makes gripping sleeve 6 end face chamfering tightly and bore, the recline gear support portion of frock 2 of the other end of gear.After gear blank fixes, can start gear blank to carry out Milling Process.
If desired, when processing has the gear of another model inner hole key slot, directly change the mandrel 3 matching, and replace mother set 1 and frock 2 without entirety.
The utility model is only applicable to the processing of endoporus single key slot gear, for the gear of other inner hole structures, needs other special fixture.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
