Description
One, technical field
The utility model relates to metal cutting machinery processing unit (plant).
Two, background technology
As everyone knows, connecting rod is the crucial high-speed moving part of engine.And being connected of engine crankshaft and connecting rod, the structure that must adopt big end to cut just can be installed and removed.Gonnecting rod body and big skull fuse with connecting-rod bolts during assembling.In order to guarantee engine reliable work, not only the requirement on machining accuracy to large and small hole of connecting rod is very high, and also is very high to the coupling bolt hole requirement on machining accuracy of gonnecting rod body and lid.Usually the bolt hole of gonnecting rod body, lid is processed respectively.Because adding the bolt hole of gonnecting rod body in man-hour, lid drills through from the two ends butt joint at twice, and the location benchmark of twice processing is inconsistent, will cause between the center of bolt hole, locating hole and counterbore of gonnecting rod body, lid, there is Concentricity tolerance, so just will inevitably cause connecting rod assembling difficulty, produce serious quality problems.
Three, summary of the invention
The utility model adopts planer-type multiaxis kinematic link bolt hole processing unit (plant), by vertical drill spindle drive internal gear, the internal gear transmission is installed on the deep hole drill on the output shaft, with gonnecting rod body, cover a plurality of bolts hole and finish processing by cutting at one time, guarantee the degree of precision of each centerline hole position, thereby solved the quality problems of Machining of Connecting Rod.
The utility model is achieved in that a kind of planer-type multiaxis kinematic link bolt hole processing unit (plant), internal gear is installed on the upright drill main shaft and by spindle drive, it between internal gear and the pinion interior engagement, each pinion is installed on output shaft top, combine as a whole with output shaft, on the tapered bore of output shaft bottom deep hole drill is installed, gear housing is fixed on the location-plate, location-plate is the level of state and is connected with two guide pillars and can moves along guide pillar is parallel up and down, the guide pillar vertical fixing is on base, on the guide pillar between location-plate and the base spring is installed, bushing plate is fixedly installed on the clamp body, and clamp body is fixed on the base.
Above-mentioned planer-type multiaxis kinematic link bolt hole processing unit (plant), pinion, output shaft are identical with deep hole drill quantity, are more than 2 or 2.
Owing to gonnecting rod body, cover and on clamp body, be big plane relative positioning and clamping, so it is consistent with the machining benchmark of locating hole, so guaranteed the machining accuracy between the center of gonnecting rod body, lid coupling bolt hole, locating hole and counterbore, improved production efficiency, reduced labour intensity.
Four, description of drawings
Fig. 1 is a planer-type multiaxis kinematic link bolt hole processing unit (plant) schematic diagram.
Among the figure, 1 is guide pillar, and 2 is location-plate, and 3 is case lid, and 4 is gear housing, and 5 is the vertical drill main shaft, 6 is pinion, and 7 is internal gear, and 8 is output shaft, and 9 is deep hole drill, and 10 is bushing plate, and 11 is drill bushing, 12 is gonnecting rod body, and 13 is connecting rod cap, and 14 is clamp body, and 15 is garden post spring, and 16 is base.
Five, the specific embodiment
Preferred forms of the present utility model is provided by following accompanying drawing.
Referring to Fig. 1, planer-type multiaxis kinematic link bolt hole processing unit (plant), form by spindle drive and clamp body two parts, the internal gear 7 of spindle drive is fixedly installed on the upright drill main shaft 5 and by spindle drive, between internal gear 7 and four pinions 6 is interior engaged transmission, each pinion 7 is installed on output shaft 8 tops, with output shaft 8 usefulness key connecting be that one is rotated synchronously, on the standard drillstock circular cone endoporus of output shaft 8 bottoms deep hole drill 9 is installed, on the output shaft 8, the below, and rolling bearing respectively is installed between the gear housing 4 supports, make four output shafts 8 under the interior engaged transmission of vertical drill main shaft 5, equidirectionally freely rotate as two point.Between output shaft 8 and the location-plate 2, the O RunddichtringO is installed, gear housing 4 usefulness Luo Ding are fixed on the location-plate 2, form the sealing gear chamber with case lid 3, gear housing 4 is fixed on the location-plate 2, location-plate 2 is the level of state and is connected with two guide pillars 1 and can be along guide pillar parallel moving about in the of 1, guide pillar 1 vertical fixing is on base 16, be separately installed with garden post spring 15 on the guide pillar 1 between location-plate 2 and the base 16, bushing plate 10 is fixedly installed on the clamp body 14, fixedly drill bushing 11 is installed on the bushing plate 10, and clamp body 14 is fixed on the base 16.Engine flat nick gonnecting rod body 12 is relative position, big plane with connecting rod cap 13 on clamp body 14, position and clamp, and machined surface is gonnecting rod body 12, connecting rod cap 13 parting surfaces, and is consistent with the machining benchmark of locating hole.Four output shafts 8 of gear-box drive four deep hole drills 9, position and the processing dimension requirement on clamp body 14 according to gonnecting rod body 12 and connecting rod cap 13, determine the depth of cut of deep hole drill 9, after processing is just finished, be positioned at the spindle drive on the location-plate 2, under 15 effects of garden post spring, make deep hole drill 9 break away from part to be processed automatically, get back to the boring front position again.When connecting rod coupling bolt hole dark 52mm of difference and 50mm, adopt the large helix angle deep hole drill 9 that is fit to production in enormous quantities, cutting effect is better.By adopting four interior engaged transmission combination drill jigs, realize four connecting rod coupling bolt hole once mounting of gonnecting rod body, lid, finished cutting simultaneously, not only guaranteed four hole machining center axial location precision, and improved labor productivity greatly, also reduced direct labor's labour intensity.This planer-type multiaxis kinematic link bolt hole processing unit (plant), pinion 7, output shaft 8 are identical with the quantity of deep hole drill 9, can be for more than 2 or 2.This device also is applicable to the porous machining occasion of the higher machinery of other required precisions zero, parts.If change the installation site of clamp body 14 on base 16, this device also is applicable to engine angular cut gonnecting rod body, the processing of lid coupling bolt hole.
