Abstract

The utility model discloses a kind of circular reverser ball nut side keyway fixture, comprise V-type base, V-type pressing plate, pin, bolt and nut, described ball nut relies on cylindrical to be clamped between V-type base and V-type pressing plate, and fixed by bolt and nut, described pin, through the reverser hole in the middle part of ball nut, is fixed on the middle part of V-type base with interference fit.The utility model uses this fixture can realize batch machining after a good workpiece coordinate of centering, need not the every independent centering of part product, naturally improves efficiency.Simultaneously, unified workpiece coordinate makes the dimensional uniformity of product have qualitative leap than single-piece centering, significantly improves installation accuracy, ensure that product quality, and labour intensity and the technical requirement of workman is greatly reduced by Cutter Body Processing with Machining Center, reduce processing cost.

Description

Circular reverser ball nut side keyway fixture
Technical field
The utility model belongs to field of machining, relates to a kind of part clamp, and particularly a kind of machine for circular reverser ball nut adds fixture.
Background technology
When processing the keyway operation in circular reverser ball nut M3205 both ends of the surface, normal employing is directly pressed on the table in general milling, because tool setting is all wanted in every one end of every part nut, cause operating efficiency low, product size uniformity is poor, labor strength increases, thus affects installation accuracy and product schedule.
Utility model content
The utility model devises a kind of circular reverser ball nut side keyway fixture, adopt this fixture can realize the keyway processing of circular reverser ball nut in enormous quantities, work in-process realizes batch machining after can adopting the good workpiece coordinate of vertical machining centre centering.
The technical solution of the utility model is as follows:
A kind of circular reverser ball nut side keyway fixture, comprise V-type base, V-type pressing plate, pin, bolt and nut, described ball nut relies on cylindrical to be clamped between V-type base and V-type pressing plate, and fixed by bolt and nut, described pin, through the reverser hole in the middle part of ball nut, is fixed on the middle part of V-type base with interference fit.
In above-mentioned circular reverser ball nut side keyway fixture, be matched in clearance between pin and reverser hole, gap is 0.01mm.
In above-mentioned circular reverser ball nut side keyway fixture, the open slot structure of being convenient to load and unload fixedly taked by the bolt at the two ends of V-type pressing plate.
In above-mentioned circular reverser ball nut side keyway fixture, V-type base has the U-type groove of stationary fixture.
In above-mentioned circular reverser ball nut side keyway fixture, the area of the base plate of V-type base is greater than the area of V-type pressing plate.
The utility model uses this fixture can realize batch machining after a good workpiece coordinate of centering, need not the every independent centering of part product, naturally improves efficiency.Meanwhile, unified workpiece coordinate makes the dimensional uniformity of product have qualitative leap than single-piece centering, significantly improves installation accuracy, ensure that product quality.And labour intensity and the technical requirement of workman is greatly reduced by Cutter Body Processing with Machining Center, reduce processing cost.

Detailed description of the invention
As Figure 1-4, circular reverser ball nut side keyway fixture, for processing keyway 8, it comprises V-type base 1, V-type pressing plate 3, pin 7, bolt 4 and nut 5, and ball nut 6 relies on cylindrical to be clamped between V-type base 1 and V-type pressing plate 3, and is fixed by bolt 4 and nut 5, pin 7 is through the reverser hole in the middle part of ball nut 6, being fixed on the middle part of V-type base 1 with interference fit, is matched in clearance between pin 7 and reverser hole, and gap is 0.01mm.
In enforcement, circular reverser borehole jack middle on M3205 ball nut 6 is entered on the pin 7 at V-type base 1 center, the inclined-plane of two in the external cylindrical surface of ball nut 6 and V-type by real, at this moment two inclined-planes of V-type just limit the movement of nut X and Z both direction, again limit the rotation of nut X and Z two axis simultaneously.And insert the pin in reverser hole because be tightly fixed on V-type base with interference, also limit the movement of nut Y-direction and the rotation of Y-axis, thus limit nut at three-dimensional six-freedom degree, achieve the location completely of nut.
Adopt the pressing plate of band V-type to add the position of compression above ball nut, make compression more reliable.Pressing plate two adopts open slot structure, and the handling of nut can be made convenient, and the gap simultaneously owing to there being 0.5 millimeter between open slot and screw rod, can prevent location.V-type base bottom adopts widening structure to increase floor space, and improve the stability of fixture, the width on top just in time can avoid the interference adding man-hour and cutter.Two U-type groove of bottom are used for stationary fixture.
When this fixture uses: first use dial gauge centering V-type base parallel with lathe Y-axis, by the U-type groove at base two ends, whole fixture is fixed on platen.Again the step in nut M3205 illustratively 1 is loaded base, then load onto V-type pressing plate, compress with screw.At the workpiece coordinate zero point of the last good nut of centering on lathe, just the keyway at face and side cutter nut processing two ends in vertical machining centre can be used.
