Abstract
A vacuum platform suitable for processing of thin-wall parts comprises a vacuum platform structure and is characterized in that the vacuum platform structure is provided with a plurality of M16 socket head cap screw holes and a plurality of M16 threaded holes, wherein the M16 socket head cap screw holes are used for fixing the vacuum structure on the surface of an operating platform of a machine table and the M16 threaded holes are used for fixing a workpiece compression plate. Besides, a plurality of seal grooves are further installed on the vacuum platform structure evenly and communicated with air suction holes which are connected with a vacuumizing device. The vacuum platform suitable for the processing of thin-wall parts utilizes the vacuumizing method to enable the bottom of a workpiece to fully contact the surface of the platform, thereby preventing the workpiece from being deformed during a machining process because the workpiece is heated. Meanwhile, adsorptive power of vacuum enhances supporting strength of the workpiece self, so that the phenomena of cutter relieving and chattering during the processing are reduced, and size accuracy and surface quality of the workpiece are improved greatly.
Description
Technical fieldThe utility model relates to a kind of clamp structure that vacuumizes, and concrete relates to a kind of vacuum platform that is applicable to processing thin-walled part.
Background technologyThin-wall construction spare is a quasi-representative structural member on the aircraft; Its principal character is that most of structural thickness size of part is very little with respect to the overall structure size; Most of structure wall thickness dimension is between 1-3mm, and the characteristic feature of thin wall component is mainly reflected in positions such as listrium, stud, web on part.
Such thin-wall construction spare has following process characteristic: the most of structure of part is weak rigid thin wall's structure; In the process of cutting, lack the influence that enough support strengths are resisted cutting force; The generation of phenomenons such as local deformation, cutter relieving, chatter has influenced dimensional accuracy and surface quality.And a little less than the whole non-deformability of part, under clamping power, internal stress effect, produce bigger bulk deformation easily, influence the processed finished products rate.
Summary of the inventionThe purpose of the utility model is that a kind of novel vacuum platform that is applicable to processing thin-walled part will be provided, and this platform structure is easy to use, clamping is quick, is specially adapted to process aviation aluminum thin-walled parts etc.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
A kind of vacuum platform that is applicable to processing thin-walled part; Comprise a vacuum platform structure, it is characterized in that: some M16 countersunk head screw hole and some M16 screwed holes that are used for fixing the workpiece increased pressure board that are used to be fixed in the platen surface are set on the vacuum platform structure; Some seal grooves also evenly are set on the vacuum platform structure, and seal groove is communicated with aspirating hole, and aspirating hole connects vacuum extractor.
Said vacuum extractor comprises the three-way valve that is connected with the aspirating hole of vacuum platform structure, vavuum pump and the plastics steel wire tube that is used to connect three-way valve and vavuum pump.
The size of said vacuum platform structure and platen measure-alike, material aluminium saw lumber matter.
The silk pitch of holes in said M16 countersunk head screw hole is decided according to platen dovetail groove spacing.
The preferred size of said seal groove is wide 6 millimeters, and dark 4.5 millimeters, spacing is decided with the practical work piece size.
After adopting such scheme, compare with existing apparatus and the utlity model has following beneficial effect:
(1) convenient mounting and clamping
Part only needs to add 2 pressing plates at two ends when clamping, has reduced the clamping time, has improved operating efficiency
(2) dimensional accuracy and surface quality have been improved
Because what adopt is that the mode that vacuumizes makes the workpiece bottom fully contact with platform surface; The distortion of having avoided workpiece in process, to produce owing to being heated; Simultaneously because the absorption affinity of vacuum has strengthened the support strength of workpiece itself; Reduce the phenomenon of cutter relieving, chatter in the processing, improved workpiece size precision and surface quality greatly.
Description of drawings
Fig. 1 is the structure vertical view of the utility model;
Fig. 2 is the structure rearview of the utility model.
Among the figure: 1, vacuum platform structure, 2, M16 countersunk head screw hole, 3, the M16 screwed hole, 4, seal groove, 5, aspirating hole, 6, three-way valve, 7, the plastics steel wire tube, 8, vavuum pump.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing:
A kind of vacuum platform that is applicable to processing thin-walled part; Comprise a vacuum platform structure 1, it is characterized in that: some M16 countersunk head screw hole 2 and some M16 screwed holes 3 that are used for fixing the workpiece increased pressure board that are used to be fixed in the platen surface are set on the vacuum platform structure 1; Some seal grooves 4 also evenly are set on the vacuum platform structure 1, and seal groove 4 is communicated with aspirating hole 5, and aspirating hole 5 connects vacuum extractor; Said vacuum extractor comprises the three-way valve 6 that is connected with the aspirating hole 5 of vacuum platform structure 1, and vavuum pump 8 and the plastics steel wire tube 7 that is used to connect three-way valve 6 and vavuum pump 8 are like Fig. 1, shown in Figure 2.
The size of said vacuum platform structure 1 and platen measure-alike, material aluminium saw lumber matter.
The silk pitch of holes in said M16 countersunk head screw hole 2 is decided according to platen dovetail groove spacing.
