Description
Technical field
[0001] the utility model belongs to a kind of assembling jig, is mainly used in the assembly that engine link thrusts or expand after being broken into body and covering and assembles, and also can be used for the assembling of other like parts.
Background technology
[0002] engine thrusts connecting rod (seeing Fig. 1,2) at present; It all is solid forging; Big end hole is processed into circle, cuts out two V-arrangement stress grooves relatively, through impacting at the big end hole inwall; Become gonnecting rod body 3 and connecting rod cap 1 along the V-shaped groove brittle fracture, be assembled into connecting rod ASSY to gonnecting rod body, connecting rod cap tension with two bolts 2 afterwards.In order to realize that gonnecting rod body 3 plane of disruption B and connecting rod cap 1 plane of disruption A can mesh assembling fully; Need with a special assembling jig; Existing assembling jig (seeing Fig. 3,4) is made up of parts such as clamp body 4, locating shaft 5, locating piece 6, opening pressing plate 7, locknut 8, left locating piece 9, right locating piece 12, screw 10, pins 11.Concrete operations penetrate with two bolts 2 in the hole of connecting rod cap 1 and gonnecting rod body 3, are inserted on the macropore locating shaft 5 after twisting in advance; Through position C, D location to gonnecting rod body 3; The locknut 8 of screwing drives opening pressing plate 7 and compresses gonnecting rod body, connecting rod cap, then on request screw-down torque two bolts 2 of screwing; Be assembled into connecting rod ASSY to gonnecting rod body 3 and connecting rod cap 1, take off connecting rod ASSY at last.
Simple in structure, the low cost of manufacture of this assembling jig; But after being assembled into connecting rod ASSY, the macropore of gonnecting rod body 3, connecting rod cap 1 can be embraced macropore locating shaft 5 inflexibly, causes the connecting rod ASSY that assembles to have 30% to unload the comparison difficulty; Time-consuming, 10% needs just can unload through beaing the back link assembly.Like this, no matter be the cylinder locating surface of macropore locating shaft 5, or the macropore locating surface of connecting rod ASSY all stays cut; Cause 5 wearing and tearing of macropore locating shaft very fast; Macropore locating shaft 5 must be changed when 160 left and right sides of average loading and unloading, and the cylindricity of the connecting rod ASSY macropore that is difficult to unload is overproof more than 0.05mm, thereby has influence on the macropore positioning accuracy of the connecting rod ASSY in the following process process; Therefore; This assembling jig can not satisfy the processing request of this procedure, badly influences the completion of manufacturing schedule, is difficult to satisfy the demand of existing batch process.
Summary of the invention
The technical problem underlying that the utility model will solve is: the locating shaft according to existing anchor clamps exist is easy to wear, the cylindricity of connecting rod ASSY macropore is prone to overproof and can not satisfy the defective of existing batch process demand.Existing anchor clamps are improved, a kind of adjustable, rational in infrastructure, easy to operate assembling jig is provided, can unload workpiece safely, quickly; The anchor clamps long service life; The cylindricity of connecting rod ASSY macropore can be not overproof, and high efficiency satisfies the demand of existing batch process.
The main technical schemes of the utility model: in the upper end hole of clamp body; Assemble a tapered locating shaft; Non-magnetic shim, spring and the La Quan of anti-rotation is equipped with on the left side of tapered locating shaft, draws circle to be fixed on the tapered locating shaft by pin, and positioning tube penetrates tapered locating shaft; Be fixedly connected on the clamp body with screw, pin; Four oblique contract pieces are respectively charged in four grooves of positioning tube, and tiltedly the width of contract piece and the groove of main locating piece are sliding fit, and left locating piece, right locating piece are installed on the clamp body through screw, pin.
The utility model proves through practical application: the connecting rod ASSY dismounting that 1, assembles has been eliminated former anchor clamps locating shaft phenomenon easy to wear easily, and the workpiece hole locating surface does not have any cut phenomenon, and the anchor clamps life-span prolongs, and has also reduced operator's labour intensity simultaneously; 2, being maintained of the cylindricity of connecting rod ASSY ability 100% can not influence the positioning accuracy of subsequent handling processing; 3, simple to operate, the workman that industrial grade is lower need not special training and also can operate, and efficient obviously improves, and constant product quality satisfies the demand that engine link is produced in batches fully.
