The utility model discloses a machining fixture for a thin-wall long thin C-shaped tubular part and belongs to the technical field of precision part machining. The machining fixture comprises a spindle, a locking nut, a compression block, a left C-shaped clamping block and a right C-shaped clamping block. The left C-shaped clamping block and the right C-shaped clamping block are arranged outside the spindle in a counterpoint mode. A symmetric long groove is formed in a side joint seam after the left C-shaped clamping block and the right C-shaped clamping block are drawn together. Circumferential inner steps are formed at one end of the long groove. Outer threads are machined at one end of the spindle. The compression block is arranged at the threaded end of the spindle in a sleeved mode. The locking nut is matched with the threads on the spindle. The left C-shaped clamping block and the right C-shaped clamping block are clamped through the compression block. According to machining fixture, the spindle location and tools such as the C-shaped blocks are adopted, so that the technical purposes of long and thin shaft machining, thin-wall part machining and deep hole machining of the thin-wall long thin C-shaped tubular part are achieved, and the machining quality and the machining efficiency of the part are greatly improved.
Description
Technical field
The utility model belongs to precision component processing technique field, relates to a kind of clamp for machining of thin-wall long and thin C shape tubular member.
Background technology
In certain aero-engine development, relate to main guide rail groove part at home, design of part as shown in Figure 1, material is 0Cr17Ni7Al, design of part feature and design parameter require more, and draw ratio is larger on the one hand, is 983/30=32.8, on the other hand, deep hole thin-walled, hole depth and aperture ratio are 983/28=35.1, wall thickness is 1mm, in addition, to have vertically width be the groove of 13mm to its structure.Because this part is domestic processing first, there is no at present ripe technological method for processing, according to domestic prior art, general thinking is for adopting machining moulding after sheet material brake forming, or adopts tubing to carry out machining to obtain part.But, adopt the sheet material brake forming impact due to material bounce-back and sheet material internal stress, be difficult to ensure designing requirement, and adopt tubing to carry out the section bar of machining without corresponding specification, and tubing is carried out to machining be also difficult to reach designing requirement.Be used as so need to design a kind of pole that adopts according to processing the processing technology that material is processed, need processing parts main guide rail groove in this technique time, need to be fixedly clamped to part, traditional machine tool fixture often easily causes tubular member flexural deformation to the clamping of thin and long units, and the structure of existing fixture is all comparatively complicated, directly cause the lower and manufacturing cost of the qualification rate of product to increase.
Utility model content
In order to address the above problem, the utility model provides a kind of clamp for machining of thin-wall long and thin C shape tubular member, thereby reaches the effect of evenly exerting pressure and clamping.
The utility model is achieved by following technical solution.
A kind of clamp for machining of thin-wall long and thin C shape tubular member, comprise mandrel, locking nut, compact heap, left C-shaped fixture block and right C-shaped fixture block, described left C-shaped fixture block and the contraposition of right C-shaped fixture block are arranged on outside mandrel, after left C-shaped fixture block and right C-shaped fixture block close up, a side commissure is a symmetrical elongated slot, there is circumferential interior step one end, described mandrel one end is processed with external screw thread, described compact heap is sleeved on the end of thread of mandrel, threaded engagement on described locking nut and mandrel, clamps left C-shaped fixture block and right C-shaped fixture block by compact heap.
Described mandrel is without being processed with vertically an elongated slot on thread segment outer wall, elongated slot width is greater than the width of the part main guide rail groove of required processing.
On described left C-shaped fixture block inwall, there is one section of circumferential step.
On described right C-shaped fixture block inwall, there is one section of circumferential step.
The beneficial effects of the utility model are:
The clamp for machining of a kind of thin-wall long and thin C shape tubular member described in the utility model, by adopting the frocks such as mandrel location and C shape piece, the technological difficulties such as the slender axles processing that thin-wall long and thin C shape tubular member relates to, thin-wall part processing, deep hole machining are solved, crudy and the efficiency of part are greatly improved, and frock clamp is simple in structure, part is easy to loading and unloading.
