Description
Technical field
The utility model belongs to the fixture that machining is used, and in particular to a kind of fixture of processing thin-wall part.
Background technology
Thin-wall part is a kind of part that commonly uses in machinery, and major surfaces are that axiality requires higher inside and outside surface of revolution,
It is extremely difficult that precision is completely secured when processing thin-walled for insider, and reason is that thin-wall part poor rigidity, intensity are weak.Thin
Wall pieces are in finishing, if to shape excircle orientation processing endoporus, as part wall is relatively thin, poor rigidity, will produce processing and become
The problem of shape, and the number of deflection effectively cannot be controlled always, element precision is difficult to ensure.In actual production process
In, existing and be difficult the phenomenons such as clamping, easily shake knife, size be unstable, processing difficulties, fault rate are high.Conventional at present is finishing
Method is to coordinate special fixture meet technical requirements by high precision digital control lathe, boring machine, grinding machine.Jig Design is often
One one frame of folder, that is, the installation way supported with four paws clamping, centre frame when processing endoporus, the requirement to equipment, fixture are all very high,
Production efficiency is also in urgent need to be improved.
For existing thin-wall part product using clamping chuck efficiency is low, fixturing surface easy damaged, thin-walled tolerance are difficult to ensure card, plus
The shortcomings of ovality is big after work, the utility model provide a kind of small volume and less weight, efficiency high, and finished size tolerance is stable
Fixture.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of folder of processing thin-wall part
Tool.The technical problems to be solved in the utility model is achieved through the following technical solutions：
A kind of fixture of processing thin-wall part, including：
Heart axle, it is the conical surface that the heart axle places the outer circumference surface of thin-wall part, on the end face that the heart axle is contacted with thin-wall part
It is provided with the shaft shoulder, it is smooth surface that the heart axle is installed on one end of lathe, the other end of the heart axle is provided with external screw thread；
The expansion set being adapted to heart axle, the expansion set are provided with cell body, and the expansion set inner surface is the conical surface, the pressing plate, swollen
Cavity is formed between set and heart axle；
Pressing plate, the outside diameter of the pressing plate are more than the interior circular diameter of expansion set；
Clamping element, the internal thread of the clamping element are coordinated with the external screw thread of heart axle.
Further, wall thickness of the height of the heart axle shaft shoulder more than thin-wall part.
Further, the expansion set is identical with the taper of the heart axle.
Further, the heart axle, the taper of expansion set are 10 °.
Further, the material of the heart axle is 45# steel.
Further, the material of the pressing plate is 45# steel.
Radial opening spring expanding principle of the utility model using expansion set, effectively solves the difficult processing of thin-wall part, chi
Very little tolerance is difficult to ensure that the technical barrier of card, the utility model small volume and less weight, efficiency high, and finished size tolerance are stable.
The utility model is described in further details below with reference to drawings and Examples.
Description of the drawings
Fig. 1 is a kind of fixture assembling schematic diagram of processing thin-wall part.
Fig. 2 is a kind of expansion set structural representation of the fixture of processing thin-wall part.
Specific embodiment
Technological means and effect that predetermined purpose is taken is reached for the utility model is expanded on further, below in conjunction with accompanying drawing
And embodiment is to specific embodiment of the present utility model, architectural feature and its effect, describe in detail as follows.
With reference to Fig. 1, Fig. 2, as the first embodiment of the present utility model, a kind of fixture of processing thin-wall part, bag
Include expansion set 2, pressing plate 3, clamping element 4 that heart axle 1 is adapted to heart axle 1, it is the conical surface that heart axle 1 places the outer circumference surface of thin-wall part, heart axle
1 end face contacted with thin-wall part is provided with the shaft shoulder, and it is smooth surface that heart axle 1 is installed on one end of lathe, and the other end of heart axle 1 sets
There is external screw thread；Expansion set 2 is provided with cell body, and 2 inner surface of expansion set is the conical surface, and heart axle 1, the taper of expansion set 2 are preferably 10 °；Pressing plate 3
Interior circular diameter of the outside diameter more than expansion set 2, so as to form cavity between pressing plate 3, expansion set 2 and heart axle 1, facilitates clamping element 4
Thin-wall part is preferably clamped, and clamping element 4 is clamped by the way of internal and external threads cooperation with heart axle 1.
As second embodiment of the present utility model, part different from the embodiment described above, it is：1 shaft shoulder of heart axle
Height more than thin-wall part wall thickness, expansion set 2 is identical with the taper of the heart axle 1, and the material of heart axle 1 is 45# steel, with quenching
The heat treatment method of 35-40HRC；The material of pressing plate 3 is 45# steel.
As spheroidal graphite cast-iron has preferable plasticity and toughness, thus the utility model is swollen from Nodular cast iron material making
Set 2, preferably spheroidal graphite cast-iron QT450-10 make expansion set 2；The utility model is provided with cell body on expansion set 2, is promoted by pressing plate 3 swollen
2 are covered, under taper effect of the heart axle 1 with expansion set 2 (heart axle 1 is preferably 10 ° with the taper of expansion set 2), is reached through taper guiding swollen
Set 2 expands, and clamps thin-wall part eventually through the expansion of expansion set 2.This clamping is contacted for face, it is to avoid point contacts the damage to thin-wall part
And processing dimension is the problems such as be difficult to ensure card.
When thin-wall part is processed, first one end for being provided with smooth surface of heart axle 1 is fixed on lathe, secondly by thin-walled
Part is placed on the conical surface of heart axle 1, and expansion set 2 is placed on the gap of heart axle 1 and thin-wall part again, the interior appearance of expansion set 2 is made
Face is close to thin-wall part inner peripheral surface, spindle end face respectively, finally places pressing plate 3, securing member 4；By turn Fastener 4,
Expand expansion set 2, most thin-wall part is clamped at last.
Above content is with reference to specific preferred embodiment further detailed description of the utility model, it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations.Ordinary skill for the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should be all regarded
For belonging to protection domain of the present utility model.
