Abstract
The invention relates to a special clamp for turning a titanium alloy thin-wall part with a complex profile. At present, when the titanium alloy thin-wall part is processed, the clamping methods such as a three-claw chuck and the like are generally adopted, so that the radial stressing of a workpiece is overlarge, the strength is poor, and the workpiece is easy to deform and difficult to position in secondary clamping. The special clamp comprises a clamping fixture (1), wherein one side of the clamping fixture is provided with a large boss (2) connected with a machine tool, and the other side of the clamping fixture is provided with a small boss (3) connected with the workpiece (4); and the small boss is connected with an outer contour fastening ring (8) by threads. The special clamp is used for turning the titanium alloy thin-wall part with the complex profile.
Description
Technical field:
The present invention relates to a kind of anchor clamps, be specifically related to a kind of special fixture that turning has complex profile titanium alloy thin wall spare that is used for.
Background technology:
At present, add to adopt clamping methods such as three-jaw chuck man-hour for titanium alloy thin wall spare more.Because the workpiece external diameter is Φ 112mm, the thickness maximum is 5.6mm, and the minimum place of profile wall thickness is 0.36mm, belong to the yielding workpiece of typical thin-walled, need guarantee the size and the precision of profile simultaneously, be difficult to clamping location and processing, can the quality of its installation way has directly had influence on processing successful.Often the clamping mode of the three-jaw chuck that adopts make that the workpiece radial force is excessive, intensity difference, mutability, the difficult location of secondary clamping, the thin wall type surface accuracy be cannot say for sure card, even occurs along the phenomenon of thin-walled place fracture, the workpiece yield rate is extremely low.
Summary of the invention:
The purpose of this invention is to provide a kind of special fixture that turning has complex profile titanium alloy thin wall spare that is used for, can effectively control cutting force, heat in metal cutting conduction, raising thin-walled profile machining accuracy in the processing, and improve the efficient of producing in batches greatly.
Above-mentioned purpose realizes by following technical scheme:
The special fixture that is used for turning complex profile titanium alloy thin wall spare, its composition comprises: mold, one side of described mold has the big boss that is connected with lathe, and the opposite side of described mold has the small boss that is connected with workpiece, and described small boss is connected with the outline tight loop by screw thread.
The described special fixture that is used for turning complex profile titanium alloy thin wall spare, profile processing mold and outer mold surface processing mold in described mold comprises, the joint face of profile processing mold and described small boss is the plane in described, and the joint face of described outer mold surface processing mold and described small boss is a convex surface.
Beneficial effect:
1. the present invention carries out radial location by the sliding pairing of axis hole workpiece, guarantees the axiality requirement.Nut and pressing plate carry out axial locking, use tight loop simultaneously and realize making the workpiece clamping force be evenly distributed to the axial locking of the peripheral profile of workpiece, avoid producing workpiece thin-walled place processing phenomenon of rupture.The size that outline tight loop and locking pressure plate are adopted be in the raising that guarantees to try one's best under the hands-off situation its requirement to clamping intensity.
. profile processing mold adopts the mode of straight plane applying clamping to process interior profile in of the present invention; Outer mold surface processing mold adopts the mode of application of a surface clamping to process outer mold surface, the curved surface of outer mold surface processing mold with process interior profile and face the mode that contacts fully directly and fit.In process, effectively play the purpose that supports and increase thin-walled portion intensity by these two kinds of applying installation way, greatly reduced workpiece and add deformation in man-hour, guaranteed the requirement of processing cutting force and precision.
. the present invention can effectively play the effect of strength support in the time of processing thin-walled, reduce resistance to cutting, makes cutting more brisk, by the increase of workpiece and mold contact area, makes the heat in metal cutting conduction accelerate, and the work-piece cools effect strengthens.Reduce cutting vibration, effectively guaranteed the size and the required precision of thin-walled profile.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is A-A profiles of accompanying drawing 1.
Accompanying drawing 3 is structural representations of interior profile processing mold.
Accompanying drawing 4 is structural representations of outer mold surface processing mold.
The specific embodiment:
Embodiment 1:
The special fixture that is used for turning complex profile titanium alloy thin wall spare, its composition comprises: mold 1, one side of described mold has the big boss 2 that is connected with lathe, the opposite side of described mold has the small boss 3 that is connected with workpiece 4, described mold is connected with outline tight loop 8 by threaded engagement, profile processing mold 1-1 and outer mold surface processing mold 1-2 in described mold comprises, the joint face of profile processing mold and small boss is the plane in described, and the joint face of described outer mold surface processing mold and small boss is a convex surface.
Described small boss has screwed hole 5 vertically, and described screwed hole connects pressing plate 6 and screw 7,
Using method:
1-1 cooperates with workpiece 4 with interior profile processing mold, fixedly outline tight loop 8 and pressing plate 6 and axial locking screw 7, and anchor clamps were to the support strength of workpiece when assurance was cut, and internal profile is processed.Then the manufactured workpiece of interior profile and outer mold surface processing mold 1-2 is cooperated, fixedly outline tight loop 8 and pressing plate 6 and axial locking screw 7, anchor clamps were processed outer mold surface then to the support strength of workpiece when assurance was cut.
Claims (2)
1. special fixture that is used for turning complex profile titanium alloy thin wall spare, its composition comprises: mold, it is characterized in that: a side of described mold has the big boss that is connected with lathe, the opposite side of described mold has the small boss that is connected with workpiece, and described small boss is connected with the outline tight loop by screw thread.
2. the special fixture that is used for turning complex profile titanium alloy thin wall spare according to claim 1, it is characterized in that: profile processing mold and outer mold surface processing mold in described mold comprises, the joint face of profile processing mold and described small boss is the plane in described, and the joint face of described outer mold surface processing mold and described small boss is a convex surface.
