Abstract
The invention relates to a machining process for a slender shaft type part of an unmachined outer circle. The machining process comprises the following steps of: (1) machining an adjustable hoop; (2) arranging the adjustable hoop on the outer circle of the shaft type part to be machined and then erecting on a central frame; (3) tightly pressing the shaft type part to be machined by using a pressing tip, adjusting a supporting bearing of the central frame to be in contact with the outer circle of the hoop, and aligning the surface of the outer circle of the hoop by using a dial gauge to overlap the surface with the center of rotation of a main shaft of a turning machine; and (4) adjusting bolts around the adjustable hoop, aligning the outer circle of the shaft type part to be machined by using the dial gauge, guaranteeing the coaxiality and then screwing up the bolts; and the pressing tip to perform turning. The process realizes that the part can be machined on the turning machine without alignment; each dimension of the machined part meets the requirements of a drawing; and the production efficiency is increased.
Description
Technical field
The present invention relates to the processing technology of the thin and long shafts part that a kind of cylindrical do not process, the thin and long shafts part that is used for not processing to foreign round carries out the processing of other end faces or endoporus etc.
Background technology
Thin and long shafts part is added man-hour, owing to workpiece length, poor rigidity, easy vibration, when receiving cutting force; Can cause bending, vibration; Processing is difficulty very, so will use during turning centre frame increasing the rigidity of workpiece usually, but uses centre frame can receive the influence of cylindrical precision; When the part cylindrical is not processed or Geometrical Tolerance Principle such as the circularity of cylindrical and axiality when having satisfied not machine and adding requirement; Only can't process qualified products with the centre frame clamping, in this case, prior art need be taked method of correcting to make part reach machine to add requirement; Again the part cylindrical is processed and satisfied the requirement of using centre frame, carry out processing such as other end faces, endoporus then.The problem that this method exists and not enough as follows:
1) part correction, processing excircles need a large amount of man-hours, waste of manpower, material resources;
2) this type of part is generally longer, proofreaies and correct the back processing excircles, can not guarantee that wall thickness is even, machine very easily occurs and adds the overproof problem in back;
3) the part correction needs large-scale press device, and very difficulty is proofreaied and correct by the unit that does not satisfy the requirements.
Summary of the invention
The technical problem that the present invention will solve provides the processing technology of the thin and long shafts part that a kind of cylindrical do not process; This technology realization part just need not be proofreaied and correct and can process at lathe; And part each item size of processing all meets drawing requirement, enhances productivity.
For overcoming the above problems, concrete technical scheme of the present invention is following: the processing technology of the thin and long shafts part that a kind of cylindrical is not processed may further comprise the steps:
1) processing a kind of adjustable clip, its structure is: the main body of clip be circularity at the pipe of 0.01mm with interior smooth in appearance, the internal diameter of pipe is than the big 20 ~ 30mm of cylindrical of axial workpiece to be processed; On the circumferencial direction of pipe, carry out the quartering, be fixedly connected 2 lugs on the corresponding end face of each Along ent respectively, bolt is threaded on each lug;
2) adjustable clip is installed on the axial workpiece cylindrical to be processed, frame is on centre frame then;
3) hold out against axial workpiece to be processed with top, the block bearing of adjustment centre frame contacts with the clip cylindrical, with dial gauge centering clip outer round surface, it is overlapped with the lathe spindle pivot;
4) bolt of adjustment around the adjustable clip used the cylindrical of dial gauge centering axial workpiece to be processed again, guarantees after the axiality bolt to be tightened, and unclamps toply, can carry out turning.
The processing technology of the thin and long shafts part that this cylindrical is not processed adopts above-mentioned steps; Can pass through adjustable clip; Pipe processing endoporus on lathe is not influenced by woollen cylindrical circularity and linearity can, directly clip frame clamping parts on centre frame is processed; Save the time of original correction and processing excircles, practiced thrift great amount of manpower and material resources; This clip manufacturing is simultaneously safeguarded simple, and easy to use, low cost of manufacture has been practiced thrift processing cost, shortens the process-cycle.
Description of drawings
Certain draw bar thin and long shafts part sketch map that Fig. 1 cylindrical is not processed.
Fig. 2 is the structural representation of adjustable clip.
The specific embodiment
As shown in Figure 1, certain draw bar pipe fitting is long to be 4484mm, and the appearance and size of blank material, wall thickness, linearity meet the specification requirement of material; But because part is long, the machine that the blank material has satisfied not part adds requirement, cause every batch all to want pincers worker and welder to proofread and correct cylindrical together after; The reprocessing endoporus; Labor man-hour, because single hole single-sided process surplus is merely 2.5mm, processing excircles very easily causes wall thickness dimension overproof simultaneously.
For enhancing productivity and guaranteeing the machining accuracy of hole in piece part, avoid overproof, adopt the processing technology of the thin and long shafts part that cylindrical do not process, may further comprise the steps:
1) processing a kind of adjustable clip, as shown in Figure 2, its structure is: the main body of clip be circularity at the pipe 1 of 0.01mm with interior smooth in appearance, the internal diameter of pipe is than the big 20 ~ 30mm of cylindrical of axial workpiece to be processed; On the circumferencial direction of pipe 1, carry out the quartering, be fixedly connected 2 lugs 2 on the corresponding end face of each Along ent respectively, bolt 3 is threaded on each lug 2;
2) adjustable clip is installed on axial workpiece 4 cylindricals to be processed, frame is on centre frame then;
3) hold out against axial workpiece to be processed with top, the block bearing of adjustment centre frame contacts with the clip cylindrical, with dial gauge centering clip outer round surface, it is overlapped with the lathe spindle pivot;
4) bolt of adjustment around the adjustable clip used the cylindrical of dial gauge centering axial workpiece to be processed again, guarantees after the axiality bolt to be tightened, and unclamps toply, can carry out turning.
Proofread and correct and the processing excircles face before this kind processing method can not need machine to add, only need to make an adjustable clip, be contained on the part and can process, time saving and energy saving, avoided overproof, raise the efficiency more than 3 times.
