Description
Technical field
The utility model relates to clamping machine tool equipment technical field, specially a kind of extra small hole of bimetallic is risen core and its clamping
Device.
Background technique
The present mainstream inner hole core that rises symmetrically is slotted on ringfeder, tightens conical surface spreading ringfeder by pull rod screw,
And then tensioner workpiece.Since the minimum aperture for the general tensioner that needs to slot is in 10mm, and the aperture of some accurate smallclothes 10mm with
Under, the core that just do not rise suitably can be used, we have used a kind of bimetallic according to many years processing precise smallclothes experience, exploitation
Rise core in extra small hole, and the small hole workpiece of 4-10mm can be processed with tensioner, and does not have to open symmetrical channels on ringfeder, by cyclic annular tensioner
Power can tensioner workpiece, carry out the processing of outer circle.
Utility model content
Rise core and its clamping device the purpose of this utility model is to provide a kind of extra small hole of bimetallic, to solve above-mentioned back
The existing cable proposed in scape technology consumes energy higher problem caused by transport is due to poorly conductive.
To achieve the above object, the utility model provides the following technical solutions: rise core and its folder for a kind of extra small hole of bimetallic
Tight device, including lathe and the core that rises, the bosom left side of the lathe are provided with cylinder, the right side central setting of the cylinder
There is air cylinder tie rod, the right side central of the lathe is equipped with ring flange, and the right side of the lathe, which is run through, is communicated with the core pull rod that rises, and
The core pull rod that rises extends to the inside of lathe, and the left end of the core pull rod that rises is fixedly connected on the right end of air cylinder tie rod by pull ring,
Nested encryptions have the core that rises on the core pull rod that rises, and are provided with ringfeder on the outside of the core that rises.
Preferably, nitriding layer is provided on the outside of the core that rises.
Preferably, the front left and right sides of the ring flange is provided with fixture.
Compared with prior art, the utility model has the beneficial effects that by solid by pull ring in the left end for the core pull rod that rises
Surely it is connected to the right end of air cylinder tie rod, nested encryptions have the core that rises on the core pull rod that rises, and ringfeder are provided on the outside of the core that rises, without rising
Symmetrical channels are put on out, air cylinder tie rod are pulled by cylinder, air cylinder tie rod pulls the core pull rod that rises to rest against the core that rises by pull ring
Cyclic annular expanding force tensioner is carried out to workpiece instead of traditional core that rises enable the smaller workpiece of core rising that rises, improve
Practicability；By being provided with nitriding layer on the outside of the core that rises, it is able to ascend the surface abrasion resistance for the core that rises, improves the use of the core that rises
Service life.
Detailed description of the invention
Fig. 1 is the utility model front portion structure schematic diagram；
Fig. 2 is the utility model insulation layer structure schematic diagram.
In figure: lathe 1, cylinder 2, air cylinder tie rod 3, ring flange 4, the core 5 that rises, ringfeder 6, the core pull rod 7 that rises, pull ring 8, fixture 9.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides the following technical solutions referring to FIG. 1-2: a kind of extra small hole of bimetallic, which is risen, core and its clamps dress
It sets, including lathe 1 and the core 5 that rises, is provided with cylinder 2 on the left of the bosom of the lathe 1, the right side central of the cylinder 2 is set
It is equipped with air cylinder tie rod 3, the right side central of the lathe 1 is equipped with ring flange 4, and the right side of the lathe 1, which is run through, is communicated with the core that rises
Pull rod 7, and the core pull rod 7 that rises extends to the inside of lathe 1, the left end of the core pull rod 7 that rises is fixedly connected on cylinder by pull ring 8
The right end of pull rod 3, nested encryptions have the core 5 that rises on the core pull rod 7 that rises, and the outside for rising by core 5 is provided with ringfeder 6.
Wherein, the outside for rising by core 5 is provided with nitriding layer 10, is able to ascend the surface abrasion resistance for the core that rises, and improves this and rises
The service life of core.
Wherein, the front left and right sides of the ring flange 4 is provided with fixture 9, convenient that workpiece is fixed, and improves
Working efficiency.
Working principle: workpiece being fixed by fixture 9, opens cylinder 2, and cylinder 2 drives air cylinder tie rod 3 to be stretched,
Air cylinder tie rod 3 drives the core pull rod 7 that rises to be stretched by pull ring 8, deforms 6 swell of ringfeder, tensioner is carried out to workpiece, due to rising
Core pull rod 7 and pull ring 8 are made using unimach 42CrMoA material, and intensity is higher, and ringfeder 6 uses high-quality spring steel
50CrVA material is process, since the particularity of structure can carry out the tensioner clamping movement in the extra small hole 10mm or less.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
