Abstract
The utility model provides a flexible tensioning device for thin-walled parts, which is characterized by mainly comprising a base, a positioning ring, a support, three or more tensioning components and a cover plate. The positioning ring and the support are mounted on the base by pins and/or screws, the cover plate is mounted on the base by studs and nuts, each tensioning component mainly consists of a tensioning block, a compression screw, the compression screws are mounted on the support by screws, and flexible media are inlaid on peripheral surfaces of the tensioning blocks. The flexible tensioning device for thin-walled parts has the advantages that centering is precise, certain clamping force is guaranteed, internal stress and deformation of parts are avoided, influences of vibration during machining of the parts on machining precision of the parts are avoided, the parts are fixed stably, measurement is convenient, and high precision of the machined thin-walled parts is guaranteed.
Description
Technical field
The tight device of traditional folder (rising) has the positioning spigot that provides certain interval, relies on clamping force to guarantee the radial position and the stability of part, adopts rigidity circumference tensioner.
Background technology
The shortcoming of the tight device of traditional folder (rising) is: excessive clamping force makes part produce internal stress and distortion, lay down clamping force after, destroyed the processing dimension of part, have a strong impact on craft precision; The vibrations in the part processing can't be eliminated, also just high-precision part can't be processed.
Summary of the invention
The purpose of the utility model is to provide a kind of clamping device that can process high-precision thin-wall part.
The utility model provides a kind of flexible swelling device of thin-wall part; It is characterized in that: mainly comprise base, locating ring, bearing, 3 or 3 above tensioner assemblies and cover plate, locating ring and bearing are contained on the base with pin and/or screw, and cover plate is contained on the base with double-screw bolt and nut; The tensioner assembly mainly comprises tightening piece; There is housing screw at the tightening piece rear portion, and housing screw is contained on the bearing and is contained on the bearing with screw, and the outer peripheral face of tightening piece studs with flexible media.
In the use; Processed thin-walled parts is placed in tentatively centering on the device positioning spigot; Carry out precision centering with dial gauge centering part center, through housing screw adjustment radial position, both guaranteed certain clamping force with torque spanner; Do not make part produce internal stress and distortion again, the flexible media that the tightening piece outer peripheral face studs with is used for eliminating the influence of the vibrations of part processing to part processing precision.
The flexible swelling device of the thin-wall part that the utility model provides; 3 or 3 above fulcrum posts can be housed on its bearing; Fulcrum post has latch assembly; Latch assembly comprises locking double-screw bolt and two lock sleeves that spiral is opposite, to eliminate the gap between fulcrum post and part, increases part fixation stability property.
The flexible swelling device of the thin-wall part that the utility model provides can have chute to match with the guide pad that is screwed on bearing on its fulcrum post, guarantee moving radially of fulcrum post.
The flexible swelling device of the thin-wall part that the utility model provides can have backing plate under its cover plate, and backing plate is contained on the cover plate with pin and/or screw, in order to avoid piece surface is scratched.
The flexible swelling device of the thin-wall part that the utility model provides can have measurement block on its base, and measurement block is contained on the base so that measure the processing dimension of part axial with pin and/or screw.
The flexible swelling device of the thin-wall part that the utility model provides, its advantage is: centering is accurately; Both guaranteed certain clamping force, and do not made part produce internal stress and distortion again; Avoid vibrations in the part processing to the influence of part processing precision; The part fixing-stable; Convenient measurement guarantees to process high-precision thin-walled parts with this.
