Description

A kind of internal-expansion type determines core fixture and application thereof

Technical field

The present invention relates to assembling field, especially a kind of internal-expansion type determines core fixture and application thereof.The present invention can be used in fixing, the clamping of cylinder cover parts, be particularly useful for the grinding of fragility thin wall cylinder cover parts, meet the process requirements of the cylinder cover parts that petroleum drilling and mining, selecting and purchasing ore deposit etc. are wear-resistant, corrosion-resistant, high temperature high voltage resistant performance requirement is higher, there is good application prospect.

Background technology

In the development process of the drilling environment comparatively dark at petroleum reservoir, geologic structure is severe and offshore oil, natural gas, usually need to adopt geological prospecting equipment slush pump, and ceramic cylinder jacket is the key fitment of slush pump.Ceramic cylinder jacket is as a kind of consumable accessory, and it uses batch large, and wall is thin, form and position tolerance and surface roughness requirements higher (ceramic cylinder jacket surface roughness can reach 0.2 ~ 0.4 μm), and it also has higher requirements to material and hardness simultaneously.

Lining of ceramic cylinder jacket earthenware belongs to large diameter thin wall part, and cylinder sleeve external diameter is about 165mm, and wall thickness is only 5.5mm.Because ceramic material thin-walled parts has the feature of high strength, high rigidity and high fragility, it is in Grinding Process, by effects such as cutting force, clamping force, grinding heat and internal stress, ceramic cylinder jacket very easily produces various types of surface/sub-surface damage, such as deformation layer, surface/sub-crizzle, ambiguity surface, phase change region, residual stress etc., and along with the carrying out of process, its blemish also may can spread and come.The existence of aforementioned drawback makes its processing and manufacturing more difficult, affects dimensional accuracy and the form accuracy of ceramic pipe fitting, is difficult to the crudy ensureing part.Therefore, clamping tool and method is reasonably selected to be the keys ensureing lining of ceramic cylinder jacket thin-wall ceramic pipe machining accuracy.

Conventional thin-walled major diameter part when carrying out grinding, first grinding part outer on general-purpose grinder, then clamp inner bore of part by one end scroll chuck of part, the top location of other end lathe.Adopt this installation way to add man-hour to ceramic cylinder jacket, in grinding process, ceramic material is little due to rigidity clamping, contact area, easily occurs brittle crack, affects the performance of product.

At present, the method for improvement mainly adopts following two class fixtures to complete the processing of part outer: rigidity mandrel fixture, elastic spindle fixture.Wherein, when adopting rigidity mandrel fixture to carry out clamping to workpiece, workpiece, using the cylindrical of rigidity axle as positioning datum, passes through face clamping.When adopting elastic spindle fixture clamping, workpiece, using the cylindrical of elastic spindle as positioning datum, by tightening or loosening pinching screw, realizes moving axially of elastic spindle.Because rigidity axle is cone match with coordinating between elastic spindle, therefore, while elastic spindle movement vertically, radial distending or contraction will be produced, thus realize the radial clamping of workpiece or unclamp.

Undeniable, the advantage of aforementioned two class fixtures is apparent.When the machining accuracy of part to be processed endoporus is higher, the fit clearance between rigidity mandrel fixture and workpiece is very little, makes the contact stiffness between workpiece and fixture very high, improves the ability of workpiece opposing chip force deformation.Meanwhile, because rigid central spindle's clamp structure is simple, number of parts is less, and the error link of generation is few, and thus easily obtain the higher fixture accuracy of manufacture, manufacturing cost is also very low.And the radial expansible of elastic spindle fixture makes it be applicable to very much the processing of the poor bulk of components of hole size uniformity.

But find after serious analysis, there is significant limitation in this two classes fixture in application.Wherein, the size adaptability of rigidity mandrel fixture is poor, and it requires that the hole size precision of part to be processed is increased, otherwise, rigidity axle will and different workpieces endoporus between radial fit gap difference suddenly big or suddenly small, the requirement of bulk of components to positional precision between positioning datum and cylindrical cannot be ensured.And though elastic spindle fixture can adapt to the larger bulk of components processing of hole size fluctuation, due to each point on spring leaf radial distending all with its root for launching in the center of circle, the radial distending amount of each point cylindrical is different in the axial direction.And for some more yielding part under external force, as sleeve thin wall component, the negative effect of clamping force to part to be processed cylindrical precision of elastic central spindle's fixture is very serious.

For this reason, in the urgent need to a kind of new fixture to solve the problem.

Summary of the invention
