Description
Technical field
The utility model relates to a kind of clamping tooling, is specially a kind of thin-wall part grinding endoporus clamping device.
Background technology
During the grinding thin-wall part, indeformable on internal grinder for guaranteeing clamping, and when having enough clamping forces to make grinding not with the emery wheel transfer, this just needs a quite reasonable clamping scheme.Be generally the centering cylindrical at present, the end face pressing plate compresses mode and processes, this mode centering difficulty because will use pressing plate, thus can only 180 degree direction centerings, False Rate is higher.The clamping inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of thin-wall part grinding endoporus clamping device is provided.
The technical scheme that provides according to the utility model, described thin-wall part grinding endoporus clamping device, it is included in the annular that the right side of gripper shoe is wholely set fin is installed, on annular installation fin, be installed with flexible sheet, on flexible sheet, be installed with three or more claw plate, all be fixed with a clamping arc plate on every block of claw plate, the section of clamping arc plate is circular arc, and every clamping arc plate is an arranged concentric, offers handle hole on the gripper shoe of corresponding clamping arc plate circle centre position; Be installed with some isometry blocks on flexible sheet, described isometry block is fixed on the flexible sheet in the zone that corresponding all clamping arc plates surround.
The number of described isometry block is identical with the number of clamping arc plate, and every isometry block all nestles up corresponding clamping arc plate setting.Every isometry block all is arranged on the center line of corresponding clamping arc plate.
Described claw plate has four, six or eight, and they are distributed on the flexible sheet.
Offer the shrinkage hole of strip on the flexible sheet between adjacent two blocks of claw plates, described shrinkage hole has the symmetrical center line of length direction, and the symmetrical center line of the length direction of shrinkage hole is arranged along the radial direction of clamping arc plate place circle.
The utlity model has following advantage:
1, adopt this covering device can be effectively, fixation workpiece reliably, improve the stability of crudy greatly.
2, adopt this covering device can effectively eliminate artificial clamping hidden danger.
3, adopt this covering device clamping facility, increase work efficiency greatly.
4, this covering device scope of application is wider, and does not have relative motion, and the life-span is longer.
5, this covering device is simple in structure, and manufacturing cost is lower.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, this thin-wall part grinding endoporus clamping device, it is included in the annular that the right side of gripper shoe 1 is wholely set fin 2 is installed, on annular installation fin 2, be installed with flexible sheet 3, on flexible sheet 3, be installed with three or more claw plate 4, all be fixed with a clamping arc plate 5 on every block of claw plate 4, the section of clamping arc plate 5 is circular arc, and every clamping arc plate 5 is an arranged concentric, offers handle hole 6 on the gripper shoe 1 of corresponding clamping arc plate 5 circle centre positions; Be installed with some isometry blocks 7 on flexible sheet 3, described isometry block 7 is fixed on the flexible sheet 3 in the zone that corresponding all clamping arc plates 5 surround.
The number of described isometry block 7 is identical with the number of clamping arc plate 5, and every isometry block 7 all nestles up 5 settings of corresponding clamping arc plate.Every isometry block 7 all is arranged on the center line of corresponding clamping arc plate 5.
Described claw plate 4 has four, six or eight, and they are distributed on the flexible sheet 3.
On the flexible sheet 3 between adjacent two blocks of claw plates 4, offer the shrinkage hole 8 of strip, described shrinkage hole 8 has the symmetrical center line of length direction, and the symmetrical center line of the length direction of shrinkage hole 8 is arranged along the radial direction of clamping arc plate 5 places circle.
During clamping workpiece, push rod 9 work, active force is out of shape elasticity lamina membranacea 3 to the right in elasticity lamina membranacea 3 to the right, and open fan-deck card claw-plate 4 and on clamping arc plate 5.With the workpiece clamping arc plate 5 of packing into, withdraw from the active force of push rod 9, elasticity lamina membranacea 3 restores to the original state, and drive fan-deck card claw-plate 4 and on clamping arc plate 5 clamping work pieces 10.The clamping arc plate 5 here will increase width as much as possible, makes it the clamping area and increases, to guarantee to reduce as much as possible clamping deformation.
Before clamping workpiece 10, the endoporus of the fan-shaped claw of elder generation's autogenous grinding, aperture reasonable in design, select only clamping force, that is to say at push rod 9 does not have active force, and elasticity lamina membranacea 3 restores to the original state, fan-deck card claw-plate 4 is under the clamped condition, autogenous grinding clamping arc plate 5 makes similar tubular body aperture that clamping arc plate 5 surrounds less than workpiece 10 external diameters, general little 0.06 ~ 0.08mm.Also can clamp the distortion situation of back workpiece 10 according to reality, adjust this magnitude of interference.The final realization guarantees enough clamping forces, make workpiece 10 when grinding not with the emery wheel transfer, guarantee not transition clamp distortion of workpiece 10 simultaneously.
