Description
Technical field
The utility model belongs to rotation class or fixed class universal machine tools annex, relates to and fixing fast and the method for designing of positioning product and technology for flexibility.
Background technology
The top type used on lathe is at present for being fixed on machine tool chief axis or tailstock, and adjusting tool stationary center mechanism, makes it for fixed product, ensures that product is fastening and locate.
This kind of top flexibility is poor, positioning performance is poor, fastening force is poor, can not regulate by teaching display stand, as on lathe during processing parts, workman often needs to need human intervention ceaselessly to carry out fastening tailstock in processing way, ensures top clamping force, thus making the workpiece bending deformed decline causing product quality, security performance reduces.
Summary of the invention
The purpose of this utility model is: the utility model provides a kind of large stroke spring center, and type is simple, flexible, versatility is good, positioning performance is reliable, energy teaching display stand regulates on a large scale.
The technical solution of the utility model is: a kind of large stroke spring center, comprising: quick change top (1), alignment pin (2), spring (3), lathe connector (4);
Described lathe connector (4) is for first half is with internal cavities, and latter half of is solid cylinder, and lathe connector (4) has stopper slot with on the sidewall of chamber portion; The cavity of lathe connector (4) first half is stretched at columniform quick change top (1) rear portion, described quick change top (1) front portion is conical, quick change top (1) rear side is provided with alignment pin (2), described alignment pin (2) stretches out from the stopper slot of lathe connector (4) sidewall, and can slide in stopper slot; Spring (3) is provided with between quick change top (1) rear portion end face and lathe connector (4) internal cavities bottom surface.
The utility model has the advantages that:
1, quick position in the process of product can be realized, Quick-clamped, can automatically regulate.
2, the utility model has saved a large amount of time to mass processing.
3, the utility model adjusts owing to there being the elastic force of spring, is greatly improved to the raising of product quality.
4, the utility model is convenient to dismounting, can realize rapid interchangeable, is convenient to maintenance.
5, the utility model is owing to adopting enclosed construction, serves larger protective effect to the safety of employee.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein 1 is that quick-changing type is top, and 2 is alignment pins, and 3 is springs, and 4 is lathe connectors.
Detailed description of the invention
Below by specific embodiment, the utility model is described further:
As shown in Figure 1, a kind of large stroke spring center of the utility model, comprising: quick change is top 1, alignment pin 2, spring 3, lathe connector 4;
Described lathe connector 4 be first half with internal cavities, latter half of is solid cylinder, and lathe connector 4 has stopper slot with on the sidewall of chamber portion; The cavity of lathe connector 4 first half is stretched at top 1 rear portion of columniform quick change, top 1 front portion of described quick change is conical, top 1 rear side of quick change is provided with alignment pin 2, and described alignment pin 2 stretches out from the stopper slot of lathe connector 4 sidewall, and can slide in stopper slot; Spring 3 is provided with between the top 1 rear portion end face of quick change and lathe connector 4 internal cavities bottom surface.
The effect that described quick change top 1 is implemented directly contacts with workpiece, and carry out location to workpiece, ensure top basic function, column part and lathe connector 4 are slidably matched.Make it move vertically, ensure and lathe axle center and workpiece axis coinciding.
The function that described alignment pin 2 realizes mainly prevents quick change top 1 from lathe connector, producing rotation, extends the life-span of quick change top 1, and ensures that quick change top 1 can only produce axially-movable in lathe connector.Alignment pin adopts universal standard pin rod, realizes quick-detachment, exchanges.
The effect that described spring 3 is implemented produces axial force to quick change top 1, make top to workpiece to be machined generation clamping force, and the automatic regulatory work on a large scale of realization used.According to the spring that the clamping force fast changeable elastic force of machined material needs differs.
Described lathe connector 4 realizes the scalable top connection with lathe of this spring, realizes the power transmission of lathe, and what ensure with lathe and workpiece is concentric.This coupling part, by measuring the main shaft of lathe or the tailstock transformation of the way for staight shank or Morse taper shank or 7:24 taper shank, realizes the spinfunction that this is top.
The described top clamping of spring extension type is firm, fast, can realize processing in enormous quantities, due to the scalable top uniform force of spring, has in actual applications reliably ensure the quality of workpiece.
Claims (1)
1. a large stroke spring center, is characterized in that, comprising: quick change top (1), alignment pin (2), spring (3), lathe connector (4);
Described lathe connector (4) is for first half is with internal cavities, and latter half of is solid cylinder, and lathe connector (4) has stopper slot with on the sidewall of chamber portion; The cavity of lathe connector (4) first half is stretched at columniform quick change top (1) rear portion, described quick change top (1) front portion is conical, quick change top (1) rear side is provided with alignment pin (2), described alignment pin (2) stretches out from the stopper slot of lathe connector (4) sidewall, and can slide in stopper slot; Spring (3) is provided with between quick change top (1) rear portion end face and lathe connector (4) internal cavities bottom surface.
