Description
Technical field
The utility model relates to a kind of fitting device more particularly to a kind of elastic expanding compact form gear-shaping clamps.
Background technique
When processing gear spline on existing YKD5132 shaping machine, inner bore of part is positioned with fixture is matched using gap
Close, end face tightens clamp nut mode by hand, due between part and apotting spindle there are certain fit clearance and part exists
It can only be clamped by hand when clamping, to cause workpiece positioning method unreasonable, positioning is inaccurate, and tooth Profile Machining precision is not met
It is required that and production efficiency it is lower.
Utility model content
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of elastic expanding compact form gear shaping folder
Tool.The elastic expanding compact form gear-shaping clamp is simple and reasonable for structure, and machining accuracy is high, simple, convenient.
The technical solution of the utility model includes pedestal, the positioning core axle being set on the pedestal, it is characterized in that described
Positioning core axle is a hollow positioning core axle, be arranged on the hollow positioning core axle one it is corresponding with corresponding workpiece and its in
The spring pocket of the mutually opposing corresponding matching of peripheral wall taper periphery wall taper corresponding to hollow positioning core axle, the spring pocket pass through
Corresponding pull rod is connected through the hollow positioning core axle inner cavity with the drawing cylinder of lathe, and the distribution of its peripheral wall of the spring pocket opens up
There is open slot being spaced apart from each other, in axial direction.
The spring pocket is fixedly connected by annular end wall set by the upper end with the pull rod.
The lower end bearing surface of positioning core axle be equipped with it is corresponding with corresponding workpiece clamp accommodating pad, it is described to clamp accommodating
Pad is that its upper wall surface is provided with evacuation ring groove corresponding with the spring pocket and clamps accommodating washer.
The positioning core axle is fixed on pedestal by the containing groove being set on the pedestal.
The utility model elastic expanding compact form gear-shaping clamp clamps the reasonability of mode due to its structure and accordingly, so that inserting
Tooth precision improves, and eliminates error caused by part and apotting spindle gap, improves part processing precision to a greater extent
And production efficiency.
Detailed description of the invention
Fig. 1 is one example structure schematic diagram of the utility model elastic expanding compact form gear-shaping clamp.
Specific embodiment
It is practical new to this by following embodiment combination attached drawing in order to further appreciate that the technical solution of the utility model
Type is described further.
As shown in Figure 1, the elastic expanding compact form gear-shaping clamp of the present embodiment includes pedestal 1, setting is passed through by corresponding screw
Open-core type positioning core axle 1 on pedestal 1, and corresponding spring pocket 6 etc. are set in the containing groove on pedestal.
Open-core type positioning core axle 1 is in upward taper, and spring pocket 6 is in downward taper, open-core type positioning core axle male cone (strobilus masculinus)
With spring pocket inner conical surface corresponding matching.Tubular spring pocket 6 is equipped with the annular end wall positioned at upper surface, and spring pocket is by thereon
The centre bore of the annular end wall at end is socketed on the bearing bulge loop platform on pull rod 9, and on the annular end wall by being located at spring pocket
The gasket 7 and locking nut 8 of side are fixed on pull rod.Pull rod is connected through hollow positioning core axle inner cavity with the drawing cylinder of lathe
It connects.The periphery wall of spring pocket 6 and the internal perisporium of workpiece are corresponding.
Its peripheral wall of its spring pocket, which is distributed, is equipped with open slot mutually evenly spaced, in axial direction, makes spring pocket peripheral wall shape
Several leaf springs annular end wall surrounding, around hollow positioning core axle periphery wall, upper thick and lower thin are connected at several the upper ends,
Several leaf spring length of spring pocket are less than or equal to the corresponding length of positioning core axle.
The height or length of the tapered portion corresponding with positioning core axle of spring pocket are equal to or less than the tapered portion of positioning core axle
Corresponding height or length so that spring pocket is sheathed on the space after positioning core axle with slide downward.It realizes in slide downward
Tensioner workpiece in the process.
It is arranged on open-core type positioning core axle and accommodates washer 4 with clamping for the wall surface corresponding matching of corresponding workpiece.
It clamps accommodating washer and is provided with evacuation ring groove corresponding with spring pocket, so that spring pocket lower end is hanging, can accommodate
The spring pocket lower end of slide downward, while it clamps accommodating washer can improve workpiece with the contact surface of workpiece by reducing
Clamp levelness.
When work, first pedestal is screwed on platen face, by apotting spindle hexagonal circle in 3 M10
Chapiter screw 2 is fixed on pedestal 1, will be clamped accommodating washer and is inserted in apotting spindle, corrects 3 outer circle pair of apotting spindle with dial gauge
The bounce of platen center is not more than 0.005mm, and it is little to platen central perpendicularity to clamp accommodating washer upper wall surface M
In 0.005mm.Spring pocket 6 is inserted in pull rod 9, spells tight spring pocket with two nuts, assembled bullet will be fixed together with pull rod
Spring set is inserted on apotting spindle 3, and pull rod 9 is screwed into lathe drawing cylinder connector.Workpiece 5 is inserted in spring pocket, is started
Machine tool hydraulic station drives tensioner free to slide on apotting spindle, clamps work under the action of spring swelling power by pull rod
Part realizes gapless work.Workpiece Machining Accuracy is improved, production efficiency is improved.
Apotting spindle and pedestal are cooperated using H7/h6, and spring pocket is made of 65Mn spring steel, so that there is enough contractions
Property, 5.7 ° of inner conical surface and 5.7 ° of carry out match grindings of apotting spindle male cone (strobilus masculinus), coordinate contact surface product are greater than 80%.Inner hole of workpiece with
Spring pocket (φ 49.7) outer circle is convenient for workpiece quick-clamping using H7 and g6 clearance fit.Spring pocket Φ 49.7g6 is to lathe worker
Make the bounce of platform center no more than 0.005mm.
