Specific embodiment
With reference to such as Fig. 1 and Fig. 2, a kind of ring-shaped thin-walled part fixture comprising circular clamp mount 1 is used to support ring
Shape thin-walled parts 2；3 limited blocks 3 being evenly arranged on clamp mount 1, for limiting the horizontal position of ring-shaped thin-walled part 2；Three
It is a be evenly arranged on clamp mount 1 with the spaced pressing plate 7 of limited block 3.
For its structure chart as shown in figure 3, a circle step 11 is circumferentially arranged in end face outermost thereon, the step 11 is low
It is arranged in upper surface 12, ring-shaped thin-walled part 2 is placed on the step 11, bottom face 24 of the step 11 to ring-shaped thin-walled part 2
It is positioned with inner ring surface 23；It is provided with a circular groove on the upper surface of the inboard clamp mount 1 of step 11, in groove
Three the first threaded holes 13 of circumference uniform distribution and three the second threaded holes 14, three the first screw threads in the main body of lower clamp support 1
Hole 13 and three the second threaded hole 14 difference uniform intervals settings；Screw rod 5 passes through the first threaded hole 13 and is threadedly coupled therewith, each
3 sets of limited block on screw rod 5, are pressed on the upper surface 12 of clamp mount 1, while the one end side of limited block 3 is tightly attached to annular
The inner ring surface 23 of thin-walled parts 2 limits the inner ring surface 23 of ring-shaped thin-walled part 2, with nut 4 be pressed on limited block 3 with
Screw rod 5 is threadedly coupled, and three limited blocks 3 are fixed on clamp mount 1 by nut 4 respectively；Same bolt 8, which is each passed through, to be set
It is threadedly coupled in the pressing plate 7 on 14 top of the second threaded hole, spring 9 and the second threaded hole 14 with the second threaded hole 14, pressing plate 7 is consolidated
The upper surface 22 that ring-shaped thin-walled part 2 is pushed down while being scheduled on clamp mount 1 carries out horizontal and vertical direction positioning to it,
If bolt 8 unscrewed, spring 9 can bounce pressing plate 7, convenient for removing ring-shaped thin-walled part 2 from clamp mount 1；?
The inboard of first threaded hole 13 and the second threaded hole 14 and with the first threaded hole 13 and the second threaded hole 15 with radial circumference uniformly distributed 6
A third threaded hole 15 is respectively provided with a screw rod in each third threaded hole 15, comes branch bearing plate 7 or limit as bearing is adjusted
Position block 3；It is provided centrally with a centre bore in clamp mount 1, convenient for connecting with other component.
First by 1 clamping to lathe of clamp mount when installation, centering clamp mount 1；Ring-shaped thin-walled part 2 is placed on
On the step 11 of clamp mount 1, with 11 coarse positioning ring-shaped thin-walled part 2 of step；Ring-shaped thin-walled part 2 is pressed in 3 pressing plates 7
On, bolt 8 is gently twisted, is not tightened；After recycle lever dial gauge centering ring-shaped thin-walled part 2, lever indicator is moved respectively
To on the intersection point of the outer surface of the radial centre lines and ring-shaped thin-walled part 2 of three limited blocks 3, share at A, B and C tri-, then
A corresponding limited block 3 is slowly realized close to ring-shaped thin-walled part 2 respectively and is limited, tightens nut 4, while observing lever hundred
The number variation of point table, numerical value variation are not greater than 0.01mm, realize to auxiliary stopper at the three of ring-shaped thin-walled part 2, subtract
Small 2 clamping power of ring-shaped thin-walled part, to reduce 2 clamping deformation of ring-shaped thin-walled part；Lever indicator is moved to respectively and three
On the intersection point of the outer surface of the radial centre lines and ring-shaped thin-walled part 2 of a pressing plate 7, share at D, E and F tri-, then respectively will be right
The pressing plate 7 answered gently is tightened again after unclamping, while observing the number variation of dial gauge, and numerical value variation is not greater than
0.01mm realizes the final fixation to ring-shaped thin-walled part 2 to eliminate part deformation caused by clamping, realizes annular thin wall zero
The three-point fix of part 2 reduces the offset of 2 clamping of ring-shaped thin-walled part, it is ensured that 2 processing quality of ring-shaped thin-walled part.
Manufacturing procedure can be reduced using the fixture stationary annular thin-walled parts 2 processing thin-wall outer 21, shortens processing
Period；Significantly reduce labor intensity of workers；Improve processing quality and product qualification rate.
The processing method of the thin-wall outer 21 of ring-shaped thin-walled part 2 is illustrated below:
Step 1: carrying out clamping to ring-shaped thin-walled part 2 with ring-shaped thin-walled part fixture；
Step 2: the thin-wall outer 21 to ring-shaped thin-walled part carries out semifinishing；
When processing, the linear velocity of part processing is 150~200m/min, and cutting feed speed is 0.1~0.15mm/r, is cut
Cutting depth is 0.2~0.25mm；First knife is since 21 right side of thin-wall outer of ring-shaped thin-walled part along thin-wall outer
Feed is processed until leaving piece surface；Second knife is since 21 left side of thin-wall outer along 21 feed of thin-wall outer
Until leaving piece surface, machining allowance stays unilateral 0.05~0.1mm for processing.
Step 3: the thin-wall outer 21 to ring-shaped thin-walled part finishes；
When processing, the linear velocity of part processing is 125~150m/min, and cutting feed speed is 0.05-0.1mm/min,
Cutting depth is 0.05~0.1mm, and feed mode is identical with second step.
Step 4: ring-shaped thin-walled part 2 is removed from ring-shaped thin-walled part fixture, inspection is qualified, the processing of the part
Terminate；
Nut 4 is backed out, limited block 5 is removed；Bolt 8 is backed out, moves pressing plate 7 away, removes 2 inspection of ring-shaped thin-walled part, is examined
Qualification, the process finishing of the part.
Using the support of clamp mount 1 and coarse positioning ring-shaped thin-walled part, limited block limit, the mode clamping zero that pressing plate compresses
Part, processing technology is simple, eliminates turning and directly causes the deformation of part to influence with the processing of pressing plate clamping ring-shaped thin-walled part；Subtract
Having lacked traditional handicraft, to repair benchmark bring process flow repeatedly long, processes the problems such as cumbersome.Improve adding for ring-shaped thin-walled part
Working medium amount and processing efficiency, reduce production cycle and processing cost, are suitble to large-scale production and processing.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
The quantity of above-described pressing plate and limited block can also be arranged other than 3 greater than 3.
