Embodiment Construction
[0011] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and technical solutions. attached figure 1 , 2 , 3, and 4 are an embodiment of the present invention. The clamping device is composed of a preliminary positioning part I, a positioning clamping part II and an installation part III. The positioning and clamping part II is composed of a first positioning and clamping mechanism A, a second positioning and clamping mechanism B, a third positioning and clamping mechanism C, and a fourth positioning and clamping mechanism D. Among them, the preliminary positioning part I can preliminarily locate the workpiece to determine the position of the workpiece, restricting one degree of freedom of displacement and two degrees of freedom of rotation of the workpiece; the positioning clamping part II is in point contact with the workpiece, and the second positioning clamp after determining the positioning...

The invention discloses a measurement and machining integrated clamping device for conical thin-wall rotating parts, belongs to the field of machining, and relates to a precise clamping device for conical thin-wall rotating body coating layer parts with special machining requirements; and the device can perform reliable clamping and precise positioning on a two-dimensional rotating worktable or amechanical arm flange plate. The clamping device consists of a primary positioning part, a positioning clamping part and a mounting part. The positioning clamping part is provided with four positioning clamping components with the same components; the positioning clamping components and workpieces are in point contact; and through cooperation of the four positioning clamping parts, the workpiecesare totally positioned and reliably clamped. The device can effectively guarantee positioning and clamping of the conical thin-wall rotating body parts, can realize measurement of clamping force and support counter force of the workpieces by once clamping and precise machining of inner and outer surfaces of the parts, is simple in operation and reliable in performance, and achieves a key effect onhigh-quality and high-precision machining of the parts.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and relates to a precision clamping device for a tapered thin-walled revolving body cladding part with special processing requirements. The device can be reliably clamped on a two-dimensional rotary workbench or a mechanical arm flange and precise positioning. Background technique [0002] In the field of aerospace, there is a kind of tapered thin-walled rotary cladding parts that require laser processing for both inner and outer surface metal cladding. Correspondence. At present, the five-axis linkage CNC machining equipment is mainly used to process the clad parts of the tapered thin-walled rotary body. However, due to the limitation of the movement space of the workbench and the limitation of the general tooling structure, it is difficult to complete the precision machining of the inner and outer surfaces of the thin-walled clad parts in one clamping. , which makes it difficult to ensure...
