Description
Technical field
This utility model is related to a kind of part clamping device, and in particular to a kind of dress for processing accumulator valve housing
Clamp device.
Background technology
Accumulator housing is the critical component in space flight valve type part, in the course of work of valve system, other phases
Close kit and will be assembled to the function that voltage stabilizing is finally realized on the housing.The part belongs to typical multiaspect flange form part, and two
There are two quincunx flanges at end, has the uniform screwed hole in 4-M8 × 1 on flange；Centre is a swinging circular flange formula cavity.
Flange size that two ends are quincunx is φ 197, and thickness is 13mm.Middle circle flange size is φ 222, and thickness is 56, two ends prunus mume (sieb.) sieb.et zucc.
Flower-shape end face of flange is seal face, and roughness is Ra0.8, planarity requirements 0.05, it is desirable to very high.
The quincunx flange arrangement lathe at two ends cannot direct clamping, it is impossible to process.The clamping work commonly used in producing at present
Dress is tightly part to be first fastened in frock using 4-M8 × 1 screw thread on quincunx flange, then lathe clamping tooling, processing
The quincunx end face of flange of the other end.The problem that the clamping tool is primarily present is that clamping process is loaded down with trivial details, longer, 80% when
Between consume part clamping and dismounting link；In addition, the big weight weight of accessory size also increased difficulty to clamping.Accumulator shell
Body belongs to batch product part, and per batch size more than 50, existing installation way clamping efficiency is relatively low, to space flight type product
The node of development and production generates impact.
The content of the invention
To solve problems of the prior art, this utility model purpose is that proposition is a kind of improves clamping efficiency
And ensure the quick positioning and clamping device of machining accuracy.
The technical scheme in the invention for solving the technical problem is：Accumulator housing seal face processing quick-clamping positioning
Device, is made up of base, bolt.The base is revolving body, and cylindrical turning processes, it is ensured that by correction during clamping
External diameter determines clamp central position；The bolt is tightened two sections of section by setting circle section and screw thread and is constituted, with positioning and twist
Tight two effects；The direct clamping of the base beat on lathe chuck table tune up it is accurate, by bolt retaining element.
Further, the direct clamping of base is played table on lathe chuck and tunes up accurate, bolt retaining element.Four positioning
It is threaded onto in four screwed holes of the quincunx end face of flange of part, it is roughly the same to be screwed into depth, four bolts are together with zero
On part inserted base in four circular holes, insertion process is easy and convenient.On base, four circular hole Position Designs have circular groove feature,
After part inserts circular hole together with bolt, rotating part bolt is slipped in revolution groove automatically, realizes the automatically fixed of part
Position, and the part centre of gyration and base central axes can be ensured, can process after screwed in place bolt, clamping process is accurate
Really, simply, conveniently.After the completion of Product processing, unscrew four bolt rotating part positioning threads and slip in four circular holes, directly
The dismounting that part had both completed part is accessed out, the installing/dismounting time of part is substantially reduced, is improve working (machining) efficiency.
This utility model beneficial effect compared with prior art is：Accumulator housing Rapid clamping positioning device is realized
The processing of accumulator is quincunx end face of flange, by accurate, simple, convenient clamping and dismounting, solves accumulator housing and adds
The problems such as work cycle length, efficiency are low, clamping process is easily damaged part；The stationarity of the course of processing is ensure that, part is improve and is added
Work efficiency rate and quality, provide strong base support to complete model task.
Description of the drawings
Fig. 1 is the accumulator housing Rapid clamping positioning device processing and loading clamp figure of the present invention.
Fig. 2 is the side view of the base of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment is described in detail.
As shown in figure 1, accumulator housing Rapid clamping positioning device described in the utility model is by bolt 1, base 3
Composition.Base 3 is revolving body, and cylindrical turning processes, it is ensured that determine clamp central position by correction external diameter during clamping.It is fixed
Position bolt 1 is tightened two sections of section by setting circle section and screw thread and is constituted, with positioning and tighten two effects.Three axle chucks 2 and base 3
Connection.
As depicted in figs. 1 and 2, base 3 is directly mounted on three axle chuck 2 of lathe during lathe process, it is outer by correction
Fixture is easily found in footpath, and bolt 1 is screwed in four screwed holes of the quincunx end face of flange of part, is screwed into depth substantially phase
Together, during four bolts are together with four circular holes on part inserted base, insertion process is easy and convenient.Rotating part is positioned
Bolt can be slipped in revolution groove automatically, realize being automatically positioned for part 4, it is ensured that 4 centre of gyration of part and 3 central axis of base
Overlap, can processing after screwed in place bolt 1.Clamping process is accurately, simply, conveniently.
After machining, unscrew four bolts, 1 rotating part positioning threads 1 and slip in four circular holes, directly take out
Part completes the dismounting of part.Due to Fixture Design reasonable simplicity, realize the processing of part end face, and ensure its roughness,
Flatness and the depth of parallelism are required；Being automatically positioned and fastening for part is realized by bolt and locating slot, convenient mounting and clamping, and can
Ensure part held stationary in process, reduce the deformation in the part course of processing, substantially increase production efficiency, be
Strong base support is provided into model task.
