Abstract
The invention relates to a method for solving manufacturing and measuring problems of a workpiece by adopting a process hole. A space hole which needs to be processed in a sample piece is taken as an example, firstly, a process hole A is designed in a processing fixture, the tolerance requirements on the size b and an alpha angle are guaranteed by measuring the distance L between the process hole A and a center hole of a drill bushing, and the size L can be measured only by inserting a check rod into the process hole A when the fixture is manufactured and detected. The process hole A is formed in a fixture body and is easy to process. When the position of the process hole A is selected, coordinate dimensions related to the process hole are reduced as much as possible, so as to simplify dimension conversion. The position dimensions of the process hole A take integers and are marked with bilateral tolerances, the distance tolerance takes plus or minus 0.01 to 0.02 mm, and the angle tolerance takes one fifth of the workpiece tolerance. The effective processing and measuring method disclosed by the invention is obtained through a plurality of practices and can be widely applied to processing and measuring processed inclined planes, drill holes of the inclined planes and space holes.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of method adopting fabrication hole to solve workpiece manufacture and a measurement difficult problem.
Background technology
At work pieces process with in measuring; often can run into processing inclined-plane, the processing problems such as boring or space inclined hole on inclined-plane, these problems be reflected in jig Design be between basal plane, relation at an angle between drill bushing axis and basal plane, between feeler block and stop surface.The size that specifies and relative-position error relation had not only been kept between not parallel but also off plumb surface for making on fixture these.This is all a difficult problem in manufacturing process and measuring technique, and technique for applying hole is often the effective ways solving a this kind of difficult problem.
Summary of the invention
For solving an above-mentioned difficult problem, the object of this invention is to provide a kind of adopt the effective ways of fabrication hole to solve workpiece measurement and processing a difficult problem.
Adopt fabrication hole to solve workpiece manufacture and measure a method for a difficult problem, to need the spatial hole of processing in exemplar; First on clamp for machining, design a fabrication hole A, ensured the tolerance at size b and α angle by the distance L between measuring technical hole A to drill bushing centre bore, in fixture manufacture with when detecting, as long as insert check rod in fabrication hole A, just can record size L.
The position of described fabrication hole A to be arranged on clamp body and should to be easy to processing.
When selecting fabrication hole A position, the coordinate dimension relevant to it should be reduced, to simplify dimension conversion as far as possible.
The position dimension round numbers of described fabrication hole A, and mark bilateral tolerance, distance tolerance value gets ± 0.01 ~ 0.02mm, and angle tolerance value gets 1/5 of workpiece tolerance.
It is by repeatedly putting into practice the very effective processing of obtained one and measuring method that the present invention adopts fabrication hole to solve workpiece manufacture and measure the method for a difficult problem, can be widely used in processing inclined-plane, drilling on inclined surface, the processing of spatial hole and measurement.
Accompanying drawing explanation
Fig. 1 is exemplar structural representation of the present invention;
Fig. 2 is the assembly structure schematic diagram of exemplar of the present invention and fixture;
Fig. 3 is relative dimensions graph of a relation in exemplar implementation process of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
The structural representation of exemplar as shown in Figure 1, in figure, workpiece will bore a space inclined hole, require the size b and α ± 3 ' that ensure workpiece, and this size cannot be measured.In order to solve this difficult problem, therefore design machined a fabrication hole A on fixture as shown in Figure 2, the tolerance at size b and α angle is ensured by the distance L between measuring technical hole A to drill bushing centre bore, in fixture manufacture with when detecting, as long as insert check rod in fabrication hole, just size L can be recorded.Be illustrated in figure 3 the geometrical relationship figure of L and b, α, obviously
L=(B+b)cosα-Rsinα
In formula: b, R, α are known, B is that jig Design is given.
From above-mentioned, the object arranging fabrication hole A is for the ease of workpiece manufacture and measurement.
Should note during the A of design technology hole following some:
The position of 1 fabrication hole A should be designed on clamp body as far as possible, and should be easy to processing;
During 2 selection fabrication hole A position, should consider to reduce the coordinate dimension relevant to it, to simplify dimension conversion as far as possible;
The best round numbers of position dimension of 3 fabrication hole A, and mark bilateral tolerance, general distance tolerance value gets ± 0.01 ~ 0.02mm, and angle tolerance value gets about 1/5 of workpiece tolerance;
The diameter of 4 fabrication hole A generally gets φ 6H7, φ 8H7, φ 10H7, adopts H7/h6 with coordinating of check rod, and the position of related features of fabrication hole axis to basal plane is not more than 0.05/100.
