Technical field
The present invention relates to Machining of Connecting Rod technical fields, more specifically, it is related to a kind of connecting rod smart car mold and application should
The Machining of Connecting Rod technique of mold.
Background technique
Connecting rod is a kind of now relatively common machine components, for connecting piston and crankshaft, will be acted on suffered by piston
Power passes to crankshaft, and the reciprocating motion of piston is changed into the rotary motion of crankshaft.As shown in Figure 1, connecting rod 1 includes 1 bar of connecting rod
Body, big end 12 and small end of connecting rod 13 offer big end hole 121 on big end 12, offer microcephaly on small end of connecting rod 13
Hole 131, big end 12 are connect by big end hole 121 with crankshaft, small end of connecting rod 13 by small head bore 131 and piston pin connection,
The thickness of big end 12 in axial direction is small with the thickness of small end of connecting rod 13 in axial direction, and big end 12 is located at and connects
The middle position of bar microcephaly 13 in axial direction.
Connecting rod 1 is usually first forged in the process processed, and then recycles milling machine to 12 He of big end
Small end of connecting rod 13 is processed, and recycles lathe to carry out turnery processing to big end hole 121 and small head bore 131 later, but existing
Process in connecting rod 1 big end hole 121 and the process processed of small head bore 131 in because to 12 hole of major part
121 and small head bore 131 centering it is relatively difficult, cause the machining accuracy of 12 hole 121 of major part and small head bore 131 not high.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of connecting rod smart car mold, by big
Head locating clip and microcephaly's locating clip feel relieved to big end hole and small head bore, improve the machining accuracy of big end hole and small head bore.
To achieve the above object, the present invention provides the following technical scheme that a kind of connecting rod smart car mold, it is characterised in that:
Chassis including cylindrical setting, is arranged on chassis top the bottom of along the connecting column for being fixedly connected on tray bottom middle position
The sliding shoe for being placed to connecting rod that disk is radially slided is arranged and is respectively used at sliding shoe both ends to big end
The major part locating clip and microcephaly's locating clip that are positioned with small end of connecting rod, be arranged on the chassis of sliding shoe two sides can be the bottom of at
The check lock lever slided along the vertical direction on disk, the latch slided along the radial direction on chassis being arranged at the top of check lock lever
And the locking cylinder in chassis for driving two check lock levers to move up and down is set；
The sliding shoe includes major part support portion and microcephaly's support portion, and the top surface of the top surface of major part support portion and microcephaly's support portion is all
Parallel with the top surface on chassis, the thickness difference of major part support portion and microcephaly's support portion is equal to big end and small end of connecting rod thickness difference
Half；
The glide direction of sliding shoe is by the axle center on chassis, and the glide direction of latch is by axle center;
Major part locating clip and microcephaly's locating clip are all made of two boards, and one end of two plates is connected with each other and two plates are mutually perpendicular to
The angle of formation angle, major part locating clip and microcephaly's locating clip is oppositely arranged.
By using above-mentioned technical proposal, the hold assemblies such as scroll chuck on lathe are realized pair by being clamped and connected column
Gripping for chassis, connecting rod is placed on sliding shoe, and big end is placed on major part support portion, and small end of connecting rod is placed on
On microcephaly's support portion, big end and small end of connecting rod are fixed using major part locating clip and microcephaly's locating clip, connecting rod is big
Head slides into chassis top center position, and slide-and-lock plate to big end can compress and not project into major part
Kong Zhong, locking cylinder drive latch by connecting bar locking, then process to big end hole；After process finishing, latch pine
The clamping to connecting rod is opened, sliding shoe is then slided and small end of connecting rod end is made to be in the middle position at the top of chassis, then adjust lock
Then the position of tight plate compresses connecting rod and carries out microcephaly so as to not project into small head bore tightly to microcephaly's side pressure again
The processing in hole；Enable to big end and connecting rod small by the support of major part support portion and microcephaly's support portion in the process of processing
The axis of head and the axis on chassis are parallel to each other, and major part locating clip and microcephaly's locating clip can prevent connecting rod from sending out in turning process
It is raw to shake, to improve the processing quality of big end hole and small head bore.
The present invention is further arranged to:: the top of two check lock levers is all fixedly connected with supporting block, and supporting block is close to sliding shoe
