Description

The float support clamp for machining
Technical field
The utility model relates to the irregular workpiece stop of a kind of profile positioning fixture, especially a kind of float support clamp for machining.
Background technology
The irregular workpiece of profile (as the turbocompressor shell) is when machined, due to the irregular positioner location difficulty of its profile, generally by push rod class positioner, it is held out against, yet in machining process, because push rod can not be fitted with its circumferential surface is perfect, workpiece can produce vibration, and distortion also easily appears in the external force that workpiece is subject to processing and pushes, and causes Workpiece Machining Accuracy low.
The utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of float support clamp for machining, and this float support clamp for machining can carry out float support to surface of the work, avoids in its process vibration and distortion occurring, guarantees machining accuracy.
The technical scheme that the utility model adopts in order to solve its technical problem: a kind of float support clamp for machining, comprise support, stop positioner and at least one float support, described stop positioner is fixed on support, workpiece to be processed can be positioned in the stop positioner in stop, the stiff end of each float support is fixed on support, and the unsteady positioning end of each float support is close to surface of the work.
As further improvement of the utility model, described stop positioner comprises positioner and clamping device, described positioner comprises the supporting bable tops that is positioned at the workpiece below and the push rod that is positioned at the workpiece periphery, described push rod is tight against workpiece periphery surface, and clamping device is positioned at the workpiece top and can be tight against the workpiece uper side surface.
As further improvement of the utility model, described clamping device comprises a door, an alignment pin and a buckle, the supporting bable tops of described alignment pin lower end and positioner is connected, alignment pin is arranged in workpiece, the alignment pin upper end is provided with the ring-type inner groovy, door be sheathed on this alignment pin and backstop in the workpiece upper end, be formed with U-shaped opening on buckle, this U-shaped opening be able to be arranged in the ring-type inner groovy of alignment pin, and buckle is tight against the door upper surface.
As further improvement of the utility model, the quantity of described float support is three, and wherein two are carried out symmetrical radial support to workpiece, and one is carried out axial support to workpiece.
As further improvement of the utility model, described float support is the float support oil cylinder.
The beneficial effects of the utility model are: the utility model is by adopting float support to carry out auxiliary positioning to the irregular workpiece of profile, it can be close to surface of the work, guarantee that workpiece not there will be vibration and distortion in process, guarantee machining accuracy, and its volume is small and exquisite, without the space, location additionally is set, be convenient to be fixed on positioning fixture, can not increase the size of positioning fixture.
The accompanying drawing explanation
Fig. 1 is structural principle front view of the present utility model;
Fig. 2 is structural principle top view of the present utility model;
Fig. 3 is float support cylinder structure principle schematic.
The specific embodiment
Embodiment: a kind of float support clamp for machining, comprise support 1, stop positioner 5 and at least one float support 3, described stop positioner 5 is fixed on support 1, workpiece 2 to be processed can be positioned in stop positioner 5 in stop, the stiff end of each float support 3 is fixed on support 1, the unsteady positioning end of each float support 3 is close to workpiece 2 surfaces, workpiece 2 is put into, the interior location of stop positioner 5, last float support 3 work, be tight against the surface at workpiece 2, can make up the irregular contour of workpiece 2 and the unfavorable factors such as the vibration there will be and distortion in machined.
Described stop positioner 5 comprises positioner 5 and clamping device 4, described positioner 5 comprises the supporting bable tops that is positioned at workpiece 2 belows and the push rod that is positioned at workpiece 2 periphery, described push rod is tight against workpiece 2 periphery surfaces, clamping device 4 is positioned at workpiece 2 tops and can be tight against workpiece 2 uper side surfaces, so just workpiece 2 is carried out axially and the location of circumferencial direction, it is maintained static.
Described clamping device 4 comprises a door, an alignment pin and a buckle, the supporting bable tops of described alignment pin lower end and positioner 5 is connected, alignment pin is arranged in workpiece 2, the alignment pin upper end is provided with the ring-type inner groovy, door be sheathed on this alignment pin and backstop in workpiece 2 upper ends, be formed with U-shaped opening on buckle, this U-shaped opening be able to be arranged in the ring-type inner groovy of alignment pin, and buckle is tight against the door upper surface, can realizes clamping or be all the replacing structure that is equal to of this structure by cylinder-pressing by thread mechanism in addition.
The quantity of described float support 3 is three, and wherein two are carried out symmetrical radial support to workpiece 2, and one is carried out axial support to workpiece 2, and workpiece 2 is carried out axially and support radially, avoids workpiece 2 adding vibration-generating damage in man-hour, distortion.
Described float support 3 is float support 3 oil cylinders, and during original state, the spring force of float support 3 oil cylinders is pressed onto bottom by plunger; While starting to supply with oil pressure, the rising piston rises in advance, and meanwhile, plunger rises to workpiece 2 and joins by spring force; After plunger touches workpiece 2, the rising piston continues to rise until top; Behind rising piston arrives top, piston starts to depress under the effect of hydraulic pressure, and the conical surface effect of piston and collet chuck produces powerful grip force by steel ball to plunger, and forms support force, the characteristic that float support 3 oil cylinders have float support 3 has auto-lock function simultaneously, guarantee to fit tightly with workpiece 2 periphery faces, its volume is small and exquisite, the heavy caliber piston, support force is powerful, also can steady operation in low pressure range, configurable at narrow space, effectively reduce the volume of fixture.
