The utility model discloses a kind of axial workpiece smart car clamping head, one end center of briquetting is equipped with spring, and the other end is step；Driving top one end is cone, and the other end is step body, and card slot is connected through a screw thread with retaining ring, and for briquetting loaded in blind hole, the card slot of blind hole mouth is provided with retaining ring；From driving top cone segments to blind via bottom to be provided with pin hole, it is sequentially installed with connecting pin and drive pin from left to right in pin hole.Direct two top of shaft-like workpiece is fixed by the tailstock centre of the present apparatus and lathe when the utility model is processed, it is top by dragging, rotary motion is carried out using part, then workpiece is prevented by bull drive pin and drives top skidding, clamped one time can process all outer circles of whole axis.When being avoided that claw clamps, part is crushed due to iron filings etc., realizes the quick-replaceable of drive pin.
Description
Technical field
The utility model relates to be machined auxiliary device, in particular to a kind of axial workpiece smart car clamping head.
Background technique
Axial workpiece before processing when, shaft-like workpiece clamping need to be fixed on lathe by tooling, so as to lathe plus
Work.At present common practice be one folder one top mode, by first processing a benchmark outer circle, then in the outer circle with claw into
Row is fixedly clamped.But it often will lead to claw because iron adsorption is on claw or benchmark outer circle in claw clamping process and crush
Part, diameter is jumped overproof and other issues after causing part to be processed.
Summary of the invention
The purpose of this utility model is to provide the axial workpiece smart car clamping head that a kind of no claw clamps, by hold out against by
The interior hole end surface of working shaft-like part makes Machining of Shaft-type Parts will not be due to claw or the mistake of benchmark outer circle outer surface in processing
Accuracy that is poor and influencing part processing, improves processing quality, improves the benefit of axial workpiece finishing.
What the purpose of this utility model was realized in.A kind of axial workpiece smart car clamping head, including briquetting and driving top
Point, one end center of the briquetting are equipped with spring, and the other end is step；Driving top one end is cone, and the other end is platform
Rank body is provided with blind hole in the step body, and the external port of blind hole is provided with card slot, and card slot is provided with internal screw thread, retaining ring setting
There is external screw thread, card slot is connected through a screw thread with retaining ring, and the diameter of diameter of blind hole and briquetting matches, and briquetting is loaded on blind hole
Interior, spring peaks at the bottom surface of blind hole, and the card slot of blind hole mouth is provided with retaining ring；Cone segments to the blind via bottom top from driving is set
It is equipped with pin hole, is sequentially installed with connecting pin and drive pin from left to right in pin hole.
The beneficial effects of the utility model are: 1) by the tailstock centre of the present apparatus and lathe that shaft-like workpiece is straight when processing
Two tops are connect to fix, it is top by dragging, rotary motion is carried out using part, then prevent workpiece and driving from pushing up by bull drive pin
Point skids.2) all outer circles of whole axis can be processed by clamped one time.3) avoid claw when clamping due to originals such as iron filings
Because crushing part.4) when drive pin, which exists, to wear, it is able to achieve the quick-replaceable of drive pin.
Detailed description of the invention
Fig. 1 is the explosive view of the utility model structure；
Fig. 2 is the schematic diagram of the utility model use state；
Fig. 3 is the stereoscopic schematic diagram of drive pin 6 in the utility model；
In figure: 1. retaining rings, 2. briquettings, 3. springs, 4. drive top, 41. pin holes, and 42. card slots, 5. connecting pins, 6. drive
Dynamic pin, 7. shaft-like workpieces, 8. tailstock centres.
Specific embodiment
Now in conjunction with drawings and examples, the utility model is described in further detail.Referring to Fig. 1 to Fig. 3, a kind of axial workpiece
Smart car clamping head, including a briquetting 2 and a driving top 4, the center of 2 one end of briquetting is fixedly installed with spring 3, separately
One end is provided with step, and the inner circle of the outer circle and retaining ring 1 of the step matches.The one end for driving top 4 is cone, the other end
For step body, it is provided with blind hole in the step body, the external port of blind hole is provided with card slot 42, and card slot 42 is provided with internal screw thread, lock
Tight ring 1 is provided with external screw thread, and card slot 42 is connected through a screw thread with retaining ring 1.Diameter of blind hole and the diameter of briquetting 2 match,
For briquetting 2 loaded in blind hole, spring 3 peaks at the bottom surface of blind hole, is connected through a screw thread in the card slot 42 of blind hole mouth equipped with retaining ring 1.
Cone segments to the blind via bottom of driving top 4 is provided with pin hole 41, is sequentially installed with 5 He of connecting pin in pin hole 41 from left to right
Drive pin 6.
The utility model when in use (as shown in Figure 2), when lathe is after connecing start button, by lathe to tailstock centre
8 one active force of application make shaft-like workpiece 7 be fixedly clamped in driving top 4 and tailstock centre 8.Lathe, which applies briquetting 2, presses
Power, carrying out power by connecting pin 5, to pass to drive pin 6(as shown in Figure 2), to the active force of drive pin 6 one to the right, and drive
The active force (wherein spring 3 have power pooling feature) by shaft-like workpiece 7 to the left simultaneously of pin 6, avoids drive pin 6 and replaces driving
Top 4 driving shaft-like workpiece 7 rotates.Shaft-like workpiece 7 because material hardness is low, while being driven the active force of pin 6 again by
To after the active force of tailstock centre 8, impression can be formed in end face surface.Drive pin 6 forms multiple in 7 piece surface of shaft-like workpiece
Impression.Multiple pressures can be generated when acting on shaft-like workpiece 7 there are three drive pin 6 by dividing equally setting in a driving top 4
Trace, this contact condition can balance the inertia force that shaft-like workpiece 8 is generated by rotation in process, prevent shaft-like workpiece 8 and drive
It moves and skids in top 4 rotary course.
Top 4 are driven to be fixed on machine chuck by soket head cap screw；It is top that retaining ring 1 is threadedly attached in driving
In 4 card slot 42；Briquetting 2 is limited by retaining ring 1 and driving top 4, can only directly be transported in top 4 blind hole inner cavity driving
It is dynamic；Spring 3 is contacted with 2 end-face central hole hole bottom face line of briquetting, and is connect with top 4 blind hole lumen end brought into linear contact is driven；
41 clearance fit of pin hole on connecting pin 5 and driving top 4, and connected with 2 bottom surface of briquetting；On drive pin 6 and driving top 4
41 clearance fit of pin hole, and with the end face of connecting pin 5 connect.
