Description
Technical field
It the utility model is related to cylinder sleeve clamp, and in particular to a kind of cylinder jacket reaming jig.
Background technology
First time roughing procedure arrangement in industry to liner blank endoporus has two kinds of technological processes：The first be with
Rough-cast Internal hole positioning, uses internal expansion type fixture tensioner endoporus.Using double V-shaped fixture to the external centring after machined, axis
To pressure side surface.Second of technique is positioned using the circular conical surface of upper lower platen, its anchor point is arranged on cylinder liner blank upper and lower ends
At the intersection of face and periphery.Positioning method is with the Internal hole positioning after thick cut with scissors, and is completed using internal expansion type fixture tensioner endoporus thick
Turning and end face.Since cylinder jacket generally uses centrifugal casting, contain certain scum in molten iron of casting, its density is less than iron
Water density, under the action of centrifuge power, scum floats on cylinder sleeve bore surface, in cylinder liner blank bore area shape after cooling
Raised into irregular scum, it is distributed and height dimension is in irregular distribution.When the 2nd, being cast due to cylinder jacket, both ends must make
With asbestos pad, and asbestos pad is than relatively soft, its two planes flatness, the depth of parallelism, thickness are all in irregular distribution, so as to make
It is discrete larger into the cylinder jacket both ends of the surface flatness, the verticality that cast out is poured.When the 3rd, being cast due to cylinder jacket, outer round surface and mould
Bore area is in close contact, and the cylindrical Surface fineness of liner blank of formation is higher, and nearer close to periphery, material structure is got over
Densification, performance are better, and interior tissue distribution is concentric with periphery, and cylinder sleeve interior tissue radially divide by performance and casting flaw
Cloth has difference.The first above-mentioned technique is using first turning and end face, rear thick fraising, since bore area has irregular point
The scum of cloth so that fixture tensioner point is in scum raised position during tensioner endoporus, causes axial line and reason that actual processing goes out
The axial line thought deviates larger, occurs the problems such as cylindrical big with the endoporus Wall-Thickness Difference, endoporus of cylinder sleeve is with cylindrical axis deviation after processing；
Simultaneously as actual axial line and theoretical axial line deviation are larger so that along the equally distributed interior tissue of periphery axial line
Structure distribution situation is disturbed, and can cause subsequently to be deformed in product and finished product cylinder jacket, it is also possible to casting flaw occurs
Increase, influences product quality.Above-mentioned second of technique is using first thick hinge cylinder cover inner hole, rear turning and end face, due to end face
Actual surface shape is undesirable, when thick hinge positions, is positioned using the conical surface, can equally cause cylinder liner blank deflection, causes actual add
The axial line that work goes out and the deviation of preferable axial line are larger, the first flow institute produced problem equally occurs.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of cylinder jacket reaming jig, Ke Yibao
Endoporus and the concentricity of periphery, the reduction cylinder jacket roughing process wall thickness formed after card liner blank first time hole machined
Process and finished product are deformed to final caused by Tissue distribution is uneven after difference, the uniformity for improving interior tissue distribution, reduction
The influence of Product Precision, reduce blank allowance and weight, Improving The Quality of Products, reduce material and processing cost.
The purpose of this utility model is achieved through the following technical solutions：
A kind of cylinder jacket reaming jig, it includes tapered sleeve and guide way, stepped hole, the guiding is offered in the tapered sleeve
Body is located in stepped hole, and the stepped hole includes hole A, bellmouth and the hole B being sequentially communicated, and the bottom of guide way and hole A coordinate,
At least three sliding slots are offered on guide way, sliding block is equipped with the sliding slot, the side of the sliding block is equipped with the table with bellmouth
The conical surface that face coordinates, sliding block are equipped with interchangeable pawl.
Preferably, the guide way bottom is equipped with spring bumper cover, and guide way bottom offers mounting hole A, the spring cup
Mounting hole B is offered at the top of plate, axial resetting spring, the axial direction resetting spring position are installed between spring bumper cover and guide way
In in mounting hole A and mounting hole B.
Preferably, the guide way is equipped with cover board, and the sliding slot, the sliding block are formed between the cover board and guide way
Radial direction resetting spring is installed between cover board, installing blind is offered on the sliding block, limit hole is offered on cover board, it is described
The both ends of radial direction resetting spring are respectively in installing blind and limit hole.
Preferably, the inner side of the interchangeable pawl is equipped with positioning disc, and three interchangeable pawls are symmetrical along the center of circle of stepped hole
Distribution.
Preferably, seam dish is installed, the top surface of the seam dish is equipped with anti-slop serrations A on the cover board.
Preferably, the sliding block is fixedly connected with interchangeable pawl by screw, and positive stop key is equipped between sliding block and interchangeable pawl.
Preferably, the positioning disc is equipped with anti-slop serrations B.
Preferably, the tapered sleeve has transition connecting disc, and the transition connection sheet is located at the lower section of spring bumper cover.
The beneficial effects of the utility model are：The locating benchmark of selection for liner blank up and down periphery, its shape
Shape and positional precision are higher, cylindrical smaller with the Wall-Thickness Difference of endoporus after thick fraising, it is possible to reduce liner blank allowance, from
And reach saving material, reduce the purpose of cost；Remain to greatest extent the parts of cylinder jacket material structure better performances not by
Cutting removes, and improves the performance of cylinder sleeve；The characteristics of due to centrifugal casting, cylinder jacket material structure performance is radially
Difference is had, and this technique utility model can guarantee that cylindrical and endoporus concentricity, reduce the deflection journey that cylinder sleeve positioning produces
Degree, thus, materials microstructure is evenly distributed along cylinder sleeve center line, and the distribution of circumferencial direction material structure is asymmetric after reducing processing
Caused by internal stress change, so as to reduce the deformation of process and finished product after cylinder sleeve；Fixture anchor point is arranged on liner blank
The a bit of cylindrical place of upper and lower ends, liner blank end surface shape, site error on positioning accuracy without influence, in clamping process
In, cylinder sleeve end face only transmits axial clamping force；Upper and lower sides fixture is constantly in mutually linkage, synchronous regime, ensures upper and lower sides certainly
Centralizer positioning, the action of clamping process are definitely consistent with the time；Instantaneous clamping, cylinder jacket upper and lower ends simultaneously clamp on,
As long as there is one end not clamp, then the other end would not clamp cylinder sleeve, and the upper and lower sides clamp time is synchronous generation, avoids clamping
The asynchronous influence to cylinder jacket centering precision.
