Description
Technical field
The utility model is related to the Set and Positioning auxiliary tool of a kind of lathe and cylindrical grinder, especially a kind of common in-vehicle mill
Lathe multi-function centre.
Background technology
In actual mechanical processing production process, when each outer surface of working shaft-like part, usually using top fixed
Position clamping method, use it is top be used as positioning datum, have unifying datum, each periphery concentricity height, small feature of beating,
It ensure that the precision of processing.And Double Tops point clamping method is exactly one of which, so-called Double Tops point clamping method is exactly except in tailstock
One end have it is top outer, main shaft one end be also inserted into one it is comparable top with spindle hole Morse's taper, be to cut band
A kind of clamping process for having the axial workpiece of different-diameter and taking, primarily to ensureing the concentricity morpheme of different-diameter section
Tolerance.The both ends of axis will stamp centre bore, also to have drive part rotation fixture (such as：Driver chuck, dead man, heart carrier
Deng).And Double Tops point positioning and clamping method is typically that heart carrier is fixed together with workpiece, then passes through dead man or driver chuck
Rotation stirs heart carrier while workpiece being driven to rotate together with.This processing method, the clamping time is long, before each work pieces process
Heart carrier will be fixed on workpiece, be removed again after processing.Sometimes heart carrier is installed on the surface processed again,
Machined complete surface is easy to scratch in clamping process, is easily reduced surface accuracy；In addition, the axis class table of installation heart carrier position
When face needs processing, usually all it is the other end that heart carrier is installed to axial workpiece, just needs two in such process
Secondary " u-turn " carries out reproduction, extremely inefficient, and the diameter range of the same heart carrier clamping workpiece to be machined is limited,
The specification of heart carrier is also chosen according to diameter of work.
Invention content
The utility model is directed to problems of the prior art, a kind of common in-vehicle grinding machine tool multifunctional top of research and design
Point, will it is existing there are four types of have a single function it is top (i.e. back dead centre, live center, spring center, drive without heart carrier it is top), return
Knot it is a kind of it is top in, can be transformed into according to the requirement of processing method and part itself desired top, improve work efficiency, ensure plus
It working medium amount and reduces labor intensity.
The utility model is made of top ontology and end cap, and one end of the top ontology is connect with end cap using screw
Together；The inside of top ontology be equipped with threaded mandrel, threaded mandrel surface be socketed holddown spring, one end of holddown spring with
Top plate connection is supported, supports the other end connection center of top plate top, two rolling bearing inner rings and the top cooperation in center, outer ring
Coordinate with the inner wall of top ontology, the top tip in center is stretched out by end cap endoporus；In the one end of threaded mandrel far from end cap
Equipped with rotating handle；The screw makes the conical surface in end cap be matched with the cone lid of top ontology；The end cap lug boss
Surface is machined with 6 driving pusher dogs；The end cap endoporus is machined with annular groove；The rotating handle outer surface is machined with anti-
Sliding annular knurl.
With the above structure, when clamping workpiece, the central aperture center of workpiece left end is top, adjustment rotation hand
Handle, adjusted under the action of holddown spring support top plate clamping force, when hold out against tailstock tool it is top when, the driving of end cap is pulled out
Pawl is just firmly embedded on the left side of workpiece, the axial cutting force that cutting process generates, and keeps driving pusher dog more firm embedding
Enter into workpiece end face, to instead of the technique using the rolling clamps driving workpiece rotation such as traditional dead man.
The utility model has the beneficial effects that：
1, the utility model has simple in structure, and construction is reasonable, simple operation, it is safe and reliable the advantages that, there are four types of existing
Have a single function it is top (i.e. back dead centre, live center, spring center, drive without heart carrier it is top), sum up in the point that a kind of top
In, reduce the usage quantity of tool, is convenient for the management of everyday tools.
2, the utility model can be transformed into the top of different function according to the requirement of processing method and part itself, use
In improve work efficiency, ensure processing quality and to reduce labor intensity, it is time saving and energy saving.

Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment：As shown in Figure 1-Figure 3, in common in-vehicle grinding machine tool multi-function centre, by top ontology 1 and end cap 2
Composition, one end of the top ontology is linked together with end cap using screw 3；Threaded mandrel is housed in the inside of top ontology
4, threaded mandrel surface is socketed holddown spring 5, and one end of holddown spring is connect with support top plate 6, and the other end of top plate is supported to connect
Center top 7, two rolling bearing inner rings 8 and the top cooperation in center are connect, outer ring and the inner wall of top ontology coordinate, and center is top
Tip stretched out by end cap endoporus；It is equipped with rotating handle 9 in the one end of threaded mandrel far from end cap；The screw makes end cap
The interior conical surface is matched with the cone lid 10 of top ontology；There are six drive pusher dog 11 for the end cap lug boss surface processing；Institute
The end cap endoporus stated is machined with annular groove, for installing sealing ring 12, impurity is prevented to be mixed into top inside；；The rotation
Handle outer surface is machined with anti-skidding annular knurl, convenient for users to light rotation rotating handle.
It is when clamping workpiece, the central aperture center of workpiece left end is top, rotating handle is adjusted at this time, by adjusting spiral shell
Line lift rod stroke pushes support top plate, supports top plate to push rolling bearing the holddown spring under the action of, to realize adjustment
The top clamping force in center；When hold out against tailstock tool it is top when, the driving pusher dog of end cap is just firmly embedded in the left side of workpiece
On, the axial cutting force that cutting process generates makes driving pusher dog more be firmly built into workpiece end face；Thus instead of adopting
With the technique of the rolling clamps such as traditional dead man driving workpiece rotation.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
