Description
Technical field
The present invention relates to a kind of profile irregular workpiece stop positioning fixture, especially a kind of float support clamp for machining.
Background technology
The irregular workpiece of profile (as 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, but in machining process, because push rod can not be fitted with its circumferential surface perfection, workpiece can produce vibration, and distortion also easily appears in the external force that workpiece is subject to processing and extrudes, and causes Workpiece Machining Accuracy low.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of float support clamp for machining, this float support clamp for machining can carry out float support to surface of the work, avoids occurring vibration and distortion in its process, ensures machining accuracy.
The technical scheme that the present invention adopts 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 stop be positioned in stop positioner, the stiff end of each float support is fixed on support, and the floating positioning end of each float support is close to surface of the work.
As a further improvement on the present invention, described stop positioner comprises positioner and clamping device, described positioner comprises the supporting bable tops be positioned at below workpiece and the push rod being positioned at workpiece periphery, described push rod is tight against workpiece periphery surface, and clamping device is positioned at above workpiece also can be tight against workpiece uper side surface.
As a further improvement on the present invention, 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, alignment pin upper end is provided with internal circumferential groove, door to be sheathed on this alignment pin and backstop in workpiece upper end, buckle is formed with U-shaped opening, this U-shaped opening be able to be arranged in the internal circumferential groove of alignment pin, and buckle is tight against door upper surface.
As a further improvement on the present invention, 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 a further improvement on the present invention, described float support is float support oil cylinder.
The invention has the beneficial effects as follows: the present invention carries out auxiliary positioning by adopting float support to the irregular workpiece of profile, it can be close to surface of the work, ensure that workpiece there will not be vibration and distortion in process, ensure machining accuracy, and its compact, without the need to additionally arranging located space, being convenient to be fixed on positioning fixture, the size of positioning fixture can not be increased.

Detailed description of the invention
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 stop be positioned in stop positioner 5, the stiff end of each float support 3 is fixed on support 1, the floating positioning end of each float support 3 is close to workpiece 2 surface, workpiece 2 is put into, stop positioner 5 inner position, last float support 3 works, be tight against the surface at workpiece 2, irregular contour and the unfavorable factor such as the vibration that there will be in machined and distortion of workpiece 2 can be made up.
Described stop positioner 5 comprises positioner 5 and clamping device 4, described positioner 5 comprises the supporting bable tops be positioned at below workpiece 2 and the push rod being positioned at workpiece 2 periphery, described push rod is tight against workpiece 2 periphery surface, clamping device 4 is positioned at above workpiece 2 also can be tight against workpiece 2 uper side surface, so just workpiece 2 is carried out to the location of axis and circumferencial direction, make it maintain 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, alignment pin upper end is provided with internal circumferential groove, door to be sheathed on this alignment pin and backstop in workpiece 2 upper end, buckle is formed with U-shaped opening, this U-shaped opening be able to be arranged in the internal circumferential groove of alignment pin, and buckle is tight against door upper surface, can realize by thread mechanism the equivalent constructions clamping or by cylinder-pressing be all this structure 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, carries out axially and radial support workpiece 2, avoids workpiece 2 vibration damage, distortion to occur adding man-hour.
Described float support 3 is float support 3 oil cylinder, and during original state, plunger is pressed onto bottom by the spring force of float support 3 oil cylinder; When starting to supply oil pressure, ascending piston rises in advance, and meanwhile, plunger rises to by spring force and connects with workpiece 2; After plunger contact to workpiece 2, ascending piston continues to rise until top; After ascending piston outreaches, piston starts pressure 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 cylinder has float support 3 has auto-lock function simultaneously, ensure to fit tightly with workpiece 2 periphery face, its compact, heavy caliber piston, support force is powerful, also can steady operation in low pressure range, at narrow space and configurable, effectively reduce the volume of fixture.
