Description
Technical field
The present invention relates to a kind of positioner, especially one kind are related to diesel engine dry cylinder body machining process middle-end
Rough mill the positioner of operation special fixture in face.
Background technology
Diesel-engine body is processed and arranges operation according to the technological principle of first face metapore, and subsequent request is with body end face and side
Positioning processing cylinder sleeve hole, guarantee cylinder sleeve uniform wall thickness, deviation are controlled in accuracy rating.
Existing body end face rough mills the positioning of operation using body both ends of the surface direction lateral surface groove alignment, milling end face.
As body blank is during cast form, (both are cast into cylinder bore wall in gap for the combination of water jacket loam core and cylinder barrel main core
It is thick) by casting to body under top board core, base plate core, end face core, (casting forms body lateral surface to sandbox, with to knife
Groove) in, the foozle of core, group core error, rigging error, the presence of casting process error can cause body appearance to carve
Line is larger with the site error of cylinder sleeve, causes the wall unevenness that follow-up cylinder sleeve boring is formed even, or even has the feelings that cylinder bore wall boring wears
Condition occurs；Illustrate that the technique of existing body end mill is unreasonable, positioning mode is inaccurate.
The content of the invention
The technical problem to be solved in the present invention is：A kind of simple structure is proposed, the positioning side in body end face rough milling
Just it is, reliable, accurate, it is ensured that it is fixed that the dry cylinder body end face of the crudy of machining cylinder block later process rough mills rotating lever formula
Position device.
The technical solution adopted in the present invention is：A kind of dry cylinder body end face rough mills rotating lever formula positioner,
Including clamp bottom board, on described clamp bottom board, parallels is fixedly installed；Support is provided with described parallels, is passed through on support
Ship and resell on another market connection rotating lever；One end of described rotating lever, the top parallel to parallels are provided with adjustable by locking nut
Support bar；Described Adjustable bracing bar is vertical with rotating lever；The other end of rotating lever is shipped and resell on another market to be provided with by another and is determined
Position roller.Described positioning roller is positioned on clamp bottom board.
When the present invention is used, body is moved on fixture parallels, is touched and is turned positioning lever, when positioning roller top upper cylinder half on lever
Set inner wall surface realizes positioning.Body that face milling is finished reverse movement, then can fall positioning lever again, be subjob
Clamping is prepared.
The invention has the beneficial effects as follows：Optimize dry cylinder body end face and rough mill operation, improve this operation exclusive clamps
The positioning mode of tool and positioner, realize being properly positioned, it is ensured that the cylinder sleeve uniform wall thickness of follow-up cylinder sleeve boring working procedure processing, carry
The machining quality of high body, reduces the percent defective of processing, the economic benefit of enterprise.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention；
In figure：1st, clamp bottom board；2nd, parallels；3rd, support；4th, Adjustable bracing bar；5th, locking nut；6th, rotating lever；7th, turn
Pin；8th, positioning roller；9th, another is shipped and resell on another market.
Specific embodiment
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further detailed explanation.These accompanying drawings are simplified
Schematic diagram, only illustrates the basic structure of the present invention in a schematic way, therefore which only shows the composition relevant with the present invention.
As shown in figure 1, a kind of dry cylinder body end face rough mills rotating lever formula positioner, including clamp bottom board, institute
Parallels is fixedly installed on the clamp bottom board stated；Support is provided with described parallels, and thick stick is rotated by connection of shipping and reselling on another market on support
Bar；One end of described rotating lever, the top parallel to parallels are provided with Adjustable bracing bar by locking nut；Described can
Adjust support bar vertical with rotating lever；The other end of rotating lever is shipped and resell on another market by another and is provided with positioning roller.Described determines
Position roller is positioned on clamp bottom board.
The boring of dry type body cylinder sleeve processes the liner backs for selecting preferably not process of roughing standard as positioning basal plane, from
And ensure processing after cylinder sleeve wall thickness it is uniform.As outer wall of cylinder jachet is wrapped in internal body, the space between two cylinders is water jacket in addition
Core is thick only to only have 4mm or so, it is impossible to anti-to put positioning original paper, so under the technological principle of first face metapore, boring sleeve port
Front operation body end face is rough milled the positioning basal plane of operation and uses sleeve port inwall black skin instead.Water in present technical process for casting
Set core (casting forms the outer surface of cylinder sleeve) core box, cylinder barrel main core (casting forms the inner surface of cylinder sleeve) core box adopt numerical control
Machine tooling, core precision are guaranteed, and sand core of water jacket and cylinder sleeve main core are installed on same top board core, positional precision
Height, casts cylinder liner blank uniform wall thickness.Basal plane is positioned as end mill roughing using sleeve port inwall black skin, equivalent to cylinder sleeve
Positioning, the selection of technological datum realizes optimization to outer surface.
The present invention positions basal plane using sleeve port inwall black skin as end mill roughing, and corresponding setting element is adopted
Positioned with rotating lever, concrete mode is：
Positioning of the body on fixture, limits 3 degree of freedom, parallels sides with parallels positioning body bottom surface (front working procedure processing)
Positioning roller positioning sleeve port inwall black skin on face positioning body bottom surface side 2 degree of freedom of margin system, rotating lever limits 1
Individual degree of freedom, workpiece are realized positioning completely.
The process of clamping workpiece is：Body is moved on fixture parallels from right to left, and rotating lever is encountered in body left side
Position is erect, is promoted lever to rotate counterclockwise, is tilted positioning roller, withstood on inboard wall of cylinder liner black skin until positioning roller, can
Till adjusting support bar to withstand on clamp bottom board, the installation positioning of workpiece is completed.During dismounting workpiece, drag body and move right, machine
Body bearing guard touches and turns lever and rotate clockwise, until last setting, is that next clamping workpiece is got ready.
The specific embodiment of the simply present invention described in description above, various illustrations reality not to the present invention
Matter Composition of contents is limited, and person of an ordinary skill in the technical field can be in the past described concrete after description has been read
Embodiment is made an amendment or is deformed, without departing from the spirit and scope of the invention.
