Description

A kind of processing unit (plant) of bent axle
Technical field
The present invention relates to a kind of bearing machining field, relate in particular to a kind of processing unit (plant) of bent axle.
Background technology
Crankshaft dynamic balance station is station indispensable in bent axle machining process, the method of current domestic elimination bent axle unbalance dynamic is all to adopt duplicate removal method, calculates according to software the quality of need to which angle on which balance weight removing how many degree of depth again by measuring amount of unbalance.In order to guarantee the accuracy of duplicate removal, need to a kind of shift fork accurately driving crank rotate a certain angle.
The shift fork of domestic design is V-type at present, this shift fork is arranged on driving-disc, can well play the effect of bent axle radial location, but this V-type shift fork maximum can compatible two kinds of bent axle types, if one bar need to process three kinds or more kinds of bent axle on Crankshaft Machining line, the shift fork of just must remodeling while remodeling, not only impact is remodeled the time, increase cost, the precision of processing also cannot guarantee.
Summary of the invention
Technical problem to be solved by this invention is the processing unit (plant) by a kind of bent axle, uses U-shaped shift fork, and the bent axle of processing B10, B12 and tri-kinds of models of B15, increases work efficiency, and reduces costs, and improves machining accuracy.
Technical scheme of the present invention is: a kind of processing unit (plant) of bent axle, comprise: driving-disc, be fixed on the bracing frame of described driving-disc one side and be fixed on the shift fork on support frame as described above, described shift fork is U-shaped, U-shaped shift fork inwall has fixed block, this fixed block is strip, chamfering is arranged at this fixed block top, and this chamfering is made up of jointly the inclined-plane on fixed block top and the inclined-plane of U-shaped shift fork inner side, and the inclined-plane of described U-shaped shift fork inner side is adjacent with the top of described fixed block.
On current production line, generally needing the bent axle product type of producing is B10, B12 and B15.The diameter of B10 type crank-shaft link neck is 38mm, and crank throw radius is 33.75mm; The diameter of B12 type crank-shaft link neck is 38mm, and crank throw radius is 39.5mm; And the diameter of B15 type crank-shaft link neck is 40mm, crank throw radius is 42.35mm.Due to these three kinds of crankshaft crank radius differences, the connecting rod neck diameter of B15 type bent axle is also different from B10 type bent axle or B12 type bent axle, use existing V-type shift fork can meet the positioning requirements of B15 type bent axle, but cannot compatible B10 type bent axle and the positioning requirements of B12 type bent axle.Because the main shaft of bent axle is fixed, and B10 type bent axle is different with the crank throw radius of B12 type bent axle, the position difference of the connecting rod neck that makes the two in V-type shift fork, but B10 type bent axle is identical with the connecting rod neck diameter of B12 type bent axle, can only rest the same position in V-type shift fork, therefore used V-type shift fork cannot compatible B10 type bent axle and the positioning requirements of B12 type bent axle.
For the driving function of compatible B10, B12, B15 type bent axle, the technical program provides a kind of U-shaped shift fork, this U-shaped shift fork is on straight inwall, the width of upper and lower opening equates, is 38mm, because B10 type bent axle is identical with the connecting rod neck diameter of B12 type bent axle, crank throw radius difference, when bent axle carries out the rotation of certain angle, the connecting rod neck of B10 type bent axle and B12 type bent axle can be at the diverse location of U-shaped shift fork inwall, and the inwall of being close to U-shaped shift fork rotates; When processing B15 type bent axle, connecting rod neck diameter maximum, is 40mm, and crank throw radius is also maximum, and the connecting rod neck of B15 type bent axle is rested in the chamfering on fixed block top, has reached the requirement of location.U-shaped like this shift fork just can be processed in B10, B12, B15 type bent axle any one as required, and does not need to change U-shaped shift fork, has improved operating efficiency, has reduced cost.Use same U-shaped shift fork processing, standard is unified, also improves machining accuracy.
Further, there is bayonet socket in described U-shaped shift fork outside, and described bayonet socket is positioned at the both sides on fork top, mirror image setting.Bayonet socket is stuck in the correspondence position of bracing frame, is convenient to fixing U-shaped shift fork, effectively avoids bracing frame to rotate the U-shaped shift fork producing and rocks, and is conducive to improve machining accuracy.
Further, described fixed block is fixed in the fixing port of U-shaped shift fork inwall, and described fixing port has two, mirror image setting.Fixed block connects closely, firmly, reduces breakage rate.The connecting rod neck of fixed block and bent axle is circumscribed, and U-shaped shift fork Reusability can cause fixed block wearing and tearing, in the time that fixed block weares and teares, only need to change fixed block, need not change U-shaped shift fork, increases work efficiency, and reduces costs.
Further, the inside opening of described fixing port is larger than outside opening, the opening of this wedge shape, effectively prevent that fixed block is towards the direction activity away from U-shaped shift fork inwall, prevented from, because of the loosening wearing and tearing that cause of fixed block, reducing the number of times of changing fixed block, increase work efficiency, reduce costs.
Further, there is kerve the inner side of U-shaped shift fork bottom, has screw on kerve, and bolt is fixed on U-shaped shift fork on bracing frame through the screw of kerve.U-shaped shift fork is installed firmly, reduces breakage rate, is conducive to reduce costs, and improves machining accuracy.
Further, there is screw the inner side at U-shaped shift fork top, and bolt, through screw, is fixed on fixed block on U-shaped shift fork.U-shaped shift fork is installed firmly, reduces breakage rate, is conducive to reduce costs, and improves machining accuracy.
Beneficial effect of the present invention: the straight inwall of U-shaped shift fork, the connecting rod neck of the bent axle of compatible B10, two kinds of models of B12, when processing B15 type bent axle, the chamfering of U-shaped shift fork is put connecting rod neck, and therefore, the U-shaped shift fork that the technical program provides can be processed the bent axle of B10, B12, tri-kinds of models of B15, do not need to change U-shaped shift fork, improved machining accuracy, raising work efficiency, reduced cost.By monthly remodeling 8 times, each save the 30 minutes time of remodeling and calculate, annual 16130.4 yuan of the costs of remodeling of saving, save 1440 hours.
