Abstract
The utility model discloses a gear hobbing clamp used in the gear hobbing working procedure of a vehicle four-range clutch shaft, which comprises a base and a sleeve barrel, wherein the base is provided with a stepped shaft, the sleeve barrel is a hollow circular barrel whose one end is provided with a centre hole and the other end is open, and the open end of the sleeve barrel is sheathed outside the base. The utility model, which adopts the mode of centralized positioning to position, has the advantages of exact position, simple structure, convenient use, convenient processing, low manufacture cost, etc., and is widely used for the positioning and the clamping of axis parts of an axis thin wall type.
Description
Technical field
The utility model relates to a kind of frock clamp, specifically, is the gear hobbing anchor clamps that use in the automobile four retaining clutch shaft gear hobbing operations.
Background technology
One procedure is arranged in manufacture process is the wheel hub gear hobbing to four retaining clutch shafts in the automobile gearbox, as adopt traditional gear-hobbing machine upper rolling tooth, need be on the three-jaw or chuck of gear-hobbing machine with workpiece one end clamping, hobboing cutter is contained on the knife rest of gear-hobbing machine, add man-hour, start gear-hobbing machine and make the workbench rotation, follow rest makes the hobboing cutter cutting workpiece and needs an end of annular knurl key to go to the other end along workpiece then.Adopt this kind processing method because of belonging to generate processing, the unidirectional side of work piece is stressed under the condition of high-speed cutting, processing for the rigidity workpiece is all right, but but can not implement for this hollow shaft of four retaining clutch shafts, because this clutch shaft rigidity is little, and belongs to thin-wall part and adopt the method annular knurl key to make axle produce distortion easily, and strong cutting vibration takes place, dimensional accuracy can't guarantee that fineness is poor.And because clutch shaft is an annular knurl key on wheel hub, wheel hub itself has been positioned at the end of axle, causes the workpiece can't clamping.The dog chuck of three-jaw is manually to clamp, and the operating time is long, and the power of being installed is not easy to be consistent.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of gear hobbing anchor clamps, to satisfy the needs of four retaining clutch shaft wheel hub gear hobbing operations, overcome the clamping inconvenience in annular knurl key process of existing hollow shaft base part, directly clamping easily produces impression, because the size that poor rigidity is brought is difficult to control, defectives such as fineness difference.
The technical scheme of the utility model technical solution problem is as follows:
A kind of clutch shaft gear hobbing anchor clamps is characterized in that, comprise base and sleeve, and described base is a multidiameter, and described sleeve is that an end has centre hole, the hollow cylinder that the other end is open, and the open end of described sleeve is enclosed within the outside of base.
Using method of the present utility model, at first base is fixedly mounted on the gear hobbing lathe, wheel hub with four retaining clutch shafts is enclosed within on the base then, then with the outside of jacket casing at four gear shafts, the bottom surface of sleeve is pressed on the horizontal plane of four gear shaft wheel hubs, at last the tailstock thimble is stretched in the centre hole of sleeve and whole clutch shaft can be fixed on the lathe, and adopt hydraulic clamp to clamp, carry out gear hobbing processing.
The utility model uses base to be fixed on the lathe, has changed traditional workpiece and directly has been fixed on mode on the lathe, has overcome traditional locate mode produces impression on workpiece defective; And the base multidiameter stretches into the mode that clutch shaft inside outside socket sleeve adopts centralized positioning, the processing rigidity that one side inner step axle has improved clutch shaft has overcome the damage of process to this thin-walled profile shaft class rigidity, improve the radial cutting force of workpiece, can improve positioning accuracy on the other hand, prevent the radially changing of the relative positions, and the utility model clamping and location of adopting common multidiameter to cooperate sleeve promptly to realize clutch shaft.Therefore the utlity model has advantages such as locating accurate, simple in structure, easy to use, easy to process and low cost of manufacture.

The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, the utility model clutch shaft gear hobbing anchor clamps comprise base 1 and sleeve 2, and described base 1 is a multidiameter, and described sleeve 2 is that an end is provided with centre hole, the hollow cylinder that the other end is open, and the open end of described sleeve is enclosed within the outside of base.
Referring to Fig. 2 and Fig. 3, described multidiameter bottom is provided with pedestal 3, and pedestal 3 is provided with installing hole, the quantity of installing hole is 6, installing hole is used for the hard-wired frame of whole base, and the other end of described pedestal 3 is provided with installs mandrel 7, mandrel 7 is installed is used for locating when base is installed.Clutch shaft 6 is enclosed within the multidiameter outside during use, and first shaft shoulder 4 of multidiameter is used for from the wheel hub of axial location clutch shaft; The maximum gauge of multidiameter is used for the clutch shaft radial location; Second section diameter of axle of multidiameter is used in the clutch shaft than the major diameter radial location; Multidiameter minimum diameter section stretches into the longer distance in clutch shaft inside, to prevent the shaft flexing distortion in the hobbing process.With behind the clutch shaft location, in the clutch shaft outside, the open end of described sleeve is provided with location flange 5 with jacket casing, and location flange 5 is used to push down the vertical edges of clutch shaft wheel hub, and finally the centre hole that stretches into sleeve by thimble is fixed whole anchor clamps.
Claims (3)
1. clutch shaft gear hobbing anchor clamps is characterized in that, comprise base and sleeve, and described base is a multidiameter, and described sleeve is for having centre hole, the hollow cylinder that the other end is open, and the open end of described sleeve is enclosed within the outside of base.
2. gear hobbing anchor clamps according to claim 1 is characterized in that, described multidiameter bottom is provided with pedestal, and pedestal is provided with installing hole, and the open end of described sleeve is provided with the location flange.
