Abstract
The invention discloses a fixture for machining a connecting rod hole, which comprises a baseboard, a guide shaft, a compressing device, a positioning block, a slide block, locking screws, a fixed board and adjusting screws; one end of the baseboard is fixedly connected with the guide shaft, and the other end of the baseboard is provided with the slide block; the slide block is further provided with guide slots and can slide in the guide slots; the slide block is further coaxially and fixedly connected with a positioning shaft; and one side of the slide block is limited by the fixed board and the adjusting screws, locking nuts are arranged on the locking screws, and the positioning block is arranged between the guide shaft and the slide block. Due to the adoption of the fixture for machining the connecting rod hole, the coaxiality of two holes can be well guaranteed only by aligning the center of a large-end hole with the positioning shaft on the slide block, so that the operation is simple, and the production efficiency of products is improved.
Description
Technical field
The present invention relates to a kind of anchor clamps, especially a kind of anchor clamps that are used to process crank pin end pore.
Background technology
The effect of connecting rod is that the power that piston bears is passed to bent axle, and makes the reciprocating motion of piston change rotatablely moving of bent axle into, and connecting rod is made up of parts such as gonnecting rod body, connecting rod cap, connecting-rod bolts and connecting rod bearing shells.Because connecting rod is one of critical piece of engine, thus its to the requirement of machining accuracy than higher, and connecting rod belongs to a kind of irregular part; The operation of its processing is many, need on different lathes, process, and the trouble that also compares the clamping of connecting rod own the time; Need carry out clamping at specific anchor clamps, wherein when big end hole and the microcephaly hole of processing connecting rod, so two holes between the also very high assurance of needs of precision of axiality; In reality processing, generally all be to process the microcephaly hole earlier, then process big end hole then; But processing like this, the precision of the axiality between two holes can not well guarantee, and the troublesome poeration of anchor clamps clamping; Cause production efficiency of products low, improved production cost.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of anchor clamps of processing tie rod holes, solved the big end hole of connecting rod and the problem that the axiality between the microcephaly hole is difficult for assurance.
Technical solution of the present invention is achieved in that a kind of anchor clamps of processing tie rod holes, comprises base plate, the axis of guide, hold down gag, locating piece, sliding shoe, lock-screw and stopping means; Said base plate one end is fixedly connected with the axis of guide, and the axis of guide is identical with the radius of connecting rod aperture; The other end of said base plate is provided with sliding shoe, and a side of sliding shoe has V-shaped groove; Also have gathering sill on the said sliding shoe, and sliding shoe can slide in gathering sill; Said gathering sill is provided with screw; Also be fixedly connected with locating shaft on the said sliding shoe, and locating shaft and the axis of guide in same in the heart; One side of said sliding shoe is provided with its spacing stopping means; Said stopping means comprises fixed head and adjustment screw; Said adjustment screw is provided with locking nut; Be provided with locating piece between the said axis of guide and the sliding shoe; Said locating piece is a U-shaped, but and the fixed support connecting rod; Also be provided with the clamping device that the connecting rod aperture is compressed on the said base plate; Said clamping device includes pressing plate, support column; Also be provided with locking nut on the said support column.
Preferably, said adjustment screw is two.
Preferably, said pressing plate is two, lays respectively at the left and right sides of workpiece.
Preferably, said gathering sill is a U-shaped.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The anchor clamps of processing tie rod holes of the present invention in processing, only need align the locating shaft on the center of big end hole and the sliding shoe; Just can well guarantee the axiality between two holes; It is simple to operate, has improved production efficiency of products, has reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing l is the structural representation of the anchor clamps of processing connecting rod macropore of the present invention;
Wherein: 1, limit shaft; 2, pressing plate; 3, clamp nut; 4, support column; 5, base plate; 6, lock-screw; 7, sliding shoe; 8, locking nut; 9, adjustment screw; 10, fixed head; 11, the axis of guide; 12, locating shaft; 13, locating piece; 14, connecting rod.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of anchor clamps of processing tie rod holes of the present invention, comprises base plate 5, the axis of guide 11, hold down gag 3, locating piece 13, sliding shoe 7, lock-screw 6, fixed head 10 and adjustment screw 9; Said base plate 5 one ends are fixedly connected with the axis of guide 11, and the axis of guide 11 is identical with the radius of connecting rod 14 apertures; The other end of said base plate 5 is provided with sliding shoe 7, and a side of sliding shoe 7 has V-shaped groove; Also have U-shaped gathering sill 11 on the said sliding shoe 7, and sliding shoe 7 can slide in gathering sill 11; Said gathering sill 11 is provided with screw; Also be fixedly connected with locating shaft 12 on the said sliding shoe 7, and locating shaft 12 and the axis of guide 11 in same in the heart; One side of said sliding shoe 7 is provided with its spacing fixed head 10 and adjustment screw 9; Said adjustment screw 9 is provided with locking nut 8; Be provided with locating piece 13 between the said axis of guide 11 and the sliding shoe 7; Said locating piece 13 is a U-shaped, but and fixed support connecting rod 14; Also be provided with the clamping device that connecting rod 14 is compressed on the said base plate 5; Said clamping device includes pressing plate 2, support column 4; Also be provided with locking nut 8 on the said support column 4; Said adjustment screw 9 is two; Said pressing plate 2 is two, lays respectively at the left and right sides of connecting rod 14.
Concrete operating process is such, at first is inserted into the microcephaly hole of workpiece on the axis of guide, is placed on workpiece on the locating piece then; Lock workpiece through the stopping means on the sliding shoe again, compress the microcephaly hole of workpiece, in processing through clamping device; Because the axis of guide and locating shaft are on same center line; As long as it is, just can well guarantee the axiality in two holes, simple to operation so let the center of workpiece big end hole and locating shaft align; Improve production efficiency, reduced production cost.
