Abstract
The invention belongs to Fixture Design technologies, are related to a kind of quick positioning and clamping device suitable for high-precision thin-wall rotation-type part internal cylindrical turning.Part is thin-wall tube like members, and wall thickness is thin, system rigidity is poor, and clamping is insecure on center lathe, and benchmark centering is difficult, so that part processing efficiency is low, precision is difficult to meet design matching requirements.The present invention includes that lathe three grabs, embraces tire and screw thread deduction cap, it is grabbed by the lathe three and the one end for embracing tire is clamped, it embraces in tire and places workpiece, screw thread deduction cap is total bottom surface and coaxial Crossed Circle structure, the end face of annular abuts the surface of workpiece, outer ring has internal thread, is connect with the external screw thread for embracing tire end.Part processing precision is effectively ensured, and easy to operate, quickly, the process-cycle it is short, product quality is stablized, and processing efficiency is also improved.
Description
Technical field
The invention belongs to Fixture Design technologies, are related to a kind of suitable for the fast of high-precision thin-wall rotation-type part internal cylindrical turning
Fast positioning and clamping device.
Background technology
Mechanical Field of Aviation Manufacturing has a large amount of high-precision thin-wall rotation-type parts, and such part is due to endoporus, outer circle precision
It is more demanding, it needs to carry out turning, boring processing.Since such part is thin-wall tube like members, wall thickness is thin, system rigidity is poor,
Clamping is insecure on center lathe, and benchmark centering is difficult, so that part processing efficiency is low, precision is difficult to meet design dress
With requirement.
Invention content
The purpose of the present invention is：It is proposed that a kind of quick positioning suitable for high-precision thin-wall rotation-type part internal cylindrical turning fills
Clamp device.
The present invention thin-wall rotation-type part internal cylindrical turning quick positioning and clamping device, the device include lathe three grab,
Tire and screw thread deduction cap are embraced, is grabbed by the lathe three and the one end for embracing tire is clamped, embraces in tire and places workpiece, screw thread deduction cap is
Bottom surface and coaxial Crossed Circle structure altogether, the end face of annular abut the surface of workpiece, and outer ring has internal thread, with an armful tire end
The external screw thread in portion connects.
The screw thread deduction cap has circumferential pin hole, and dynamics is tightened by the adjusting of elastic pin.
The inner surface of described armful of tire is matched with workpiece with form surface, and maximal clearance is not more than 0.03mm.
There is stepped hole, the smaller interior hole end surface in aperture provides support to workpiece, larger outer in aperture inside described armful of tire
Portion's hole depth is more than the height of workpiece.
The beneficial effects of the invention are as follows：Be accurately positioned by special armful of tire, mandrel and slack adjuster, can be stable by this
Thin-wall rotation-type part is fixed on this device, is added by screwing the turning on numerically-controlled machine tool of slack adjuster and nut retaining element
Work.
This device solves the problems, such as high-precision thin-wall rotation-type part inside and outside circle turnery processing so that part processing precision energy
Access and be effectively ensured, and is easy to operate, quickly, the process-cycle it is short, product quality is stablized, and processing efficiency is also improved.
Description of the drawings
Fig. 1 is the clamping schematic diagram of quickly positioning and clamping device of the invention.
Wherein, 1- lathes three are grabbed, 2- embraces tire, 3- workpiece, 4- screw threads deduction cap, the elastic pins of 5-
Specific implementation mode
The invention belongs to Fixture Design technologies, are related to a kind of suitable for the fast of high-precision thin-wall rotation-type part internal cylindrical turning
Fast positioning and clamping device, including lathe three grab 1, embrace tire 2 and screw thread deduction cap 4, when machining accuracy endoporus, workpiece 3 are put into and embraces a tire 2
Hole in, grab the tail end that tire 2 is embraced in 1 clamping with lathe three, then slowly screw screw thread deduction cap 4 to clasping workpiece 3, and to screw thread
Pin hole in 4 circumferential direction of deduction cap controls threaded tightening force degree by elastic pin 5, that is, completes precision endoporus processing and loading clamp process.
