Abstract
The invention relates to a method for processing an exact fit assembly part. Firstly, each component of the assembly part is singly treated by rough processing, normalizing treatment and fine processing on non-exact fit parts, and exact fit parts are treated by combined fine processing; and the combined fine processing of the exact fit parts is carried out by installing each component on the combined type clamp in a combined way, firstly, each component is fixed on an auxiliary clamp by a threaded rod, secondly, the auxiliary clamp is fixed on a main clamp by a threaded rod so that the components can be combined together on the main clamp, thirdly, fine processing is carried out on the exact fit parts on the main clamp, and after processing, the components are disassembled from the clampsand are correspondingly numbered. The method is especially suitable for processing components of a bottle blowing machine, such as moveable and fixed mould frames, and solves the problems of the traditional method: 1. as the mode of combined processing is adopted, the dimension thereof can meet the requirement of matching with dimensional accuracy; and 2. as the combined type clamp dispenses withwelding, deformation caused by welding can not be generated before or after processing.
Description
Technical field
The present invention relates to the composite class machining parts, particularly a kind of processing method that needs the component parts of precision-fit.
Background technology
What for a long time, the processing of component parts was taked is traditional processing method.For example process moving, the cover half frame of bottle blowing machine, technical combination size is had relatively high expectations, and there are a large amount of problems in traditional processing method.
Traditional diamond-making technique one: with the processing respectively separately of active and inactive mold frame.
With dynamic model mould bases roughing groove, rough mill face, thick boring; Carry out normalized treatment then, finish-milling groove, fine finishining until completion of processing, with cover half mould bases completion of processing too, combine dynamic model mould bases and cover half mould bases according to matching requirements everywhere at last again.
The problem that this processing method exists:
All there are mismachining tolerance in the dynamic model mould bases of a, separate machined and cover half mould bases, and these mismachining tolerances guarantee its fit dimension after making two workpiece be difficult in combination fully;
B, the size after will guaranteeing better to make up, the precision of each workpiece in the time of certainly will will significantly improving separate machined, this had both increased difficulty of processing, had significantly improved processing cost again.
Traditional diamond-making technique two: roughing separately earlier, normalizing, finish-milling groove, will move, the processing welded together of cover half frame then.
With dynamic model mould bases roughing groove, rough mill face, thick boring; Carry out normalized treatment then, the finish-milling groove is processed the cover half mould bases too again, again dynamic model mould bases and cover half mould bases are welded fine finishining, remove pad afterwards, cover half mould bases and dynamic model mould bases are taken apart, according to matching requirements cover half mould bases and dynamic model mould bases are combined again.
The problem that this processing method exists:
A, increase the operation of welding, dismounting, improved cost;
After b, each operation of roughing, require to guarantee the dimensional requirement of Working position separately in the welding, increased the welding difficulty.
C, welding and demolishing process, workpiece all produce distortion, cause can't guaranteeing to make up the required precision of size.
Summary of the invention
Present in the processing of the component parts that requires precision-fit in order to overcome, difficulty of processing is big, cost is high, the precision of combination size is difficult for the shortcoming of assurance, the present invention proposes a kind of new processing method of using anchor clamps.
This processing method that needs the component parts of precision-fit, earlier the various piece of component parts is carried out roughing separately, normalized treatment and to the fine finishining at non-precision-fit place, then to combination the carrying out fine finishining of precision-fit place, it is characterized in that, fine finishining is carried out in precision-fit place combination to be installed in each part combination on the convolution anchor clamps and to carry out, anchor clamps comprise main folder tool and auxiliary clamp, earlier each part is fixed on the auxiliary clamp with screw rod, again auxiliary clamp is fixed on the main folder tool with screw rod, each part is combined on the main folder tool, on the main folder tool, the precision-fit place is carried out fine finishining then, after processing each part is pulled down from anchor clamps, corresponding number on the volume, so that the part with respective number is assembled together later on, below to process the moving of bottle blowing machine, the cover half frame is that example describes.
The dynamic model mould bases of bottle blowing machine and cover half mould bases, they are two slices watts of shapes, watt two sides 3～4 ears or side handles of a utensil are arranged, coaxial hole is arranged on the ears or side handles of a utensil, and assembling back forms cylindric, in the design to cylindricity, the aperture of the macropore of centre, relative position, the depth of parallelism, axiality to two groups of earholes all have requirement, add man-hour, 1. earlier with dynamic model mould bases and cover half mould bases, carry out the roughing groove, rough mill face, slightly hole; Normalized treatment; Finish-milling groove, finish-milling locating surface; 2. dynamic model mould bases and cover half mould bases are fixed on respectively on the auxiliary clamp separately, dynamic model mould bases auxiliary clamp is a rectangular slab, the middle part has 2 holes corresponding with prior brill 2 locating holes well on the dynamic model mould bases arc surface, with 2 alignment pins and 4 screw rods the dynamic model mould bases is fixed on the dynamic model mould bases auxiliary clamp, use the same method, the cover half mould bases is fixed on the cover half mould bases auxiliary clamp; 3. will move, cover half frame auxiliary clamp is fixed on the main folder tool, main folder has a rectangular base plate, base plate respectively has a pillar for four jiaos, there is a short beam the two pillars upper end on the narrow limit of base plate, cover half mould bases auxiliary clamp is fixed on the base plate with 2 alignment pins and 4 screw rods, dynamic model mould bases auxiliary clamp is fixed on two short beams with 2 alignment pins and 4 screw rods, will moves, the cover half mould bases combines; 4. the fine finishining after middle macropore and two groups of earholes being made up; 5. will move, the cover half mould bases disassembles from anchor clamps, and is equipped with corresponding numbers, so that corresponding part is fitted together when assembling later on.
This processing method has solved the problem in the conventional method:
1, owing to be the processing that combines, its size can satisfy the requirement of fit dimension precision;
2, these convolution anchor clamps make up workpiece fixingly under free state, need not welding, therefore can not produce the distortion that causes because of welding before and after the processing.
