Double End string milling machine for crank connecting link
Technical field
The present invention relates to auto parts and components manufacture fields, in particular to are used for the Double End string milling machine of crank connecting link.
Background technique
The shape of crank connecting link is more complicated, is easily deformed, poor rigidity, dimensional accuracy, position precision and surface quality
Etc. more demanding, have in manufacture and acquire a certain degree of difficulty.And the quality of its connecting rod manufacturing technology directly affects the usability of connecting rod
Can and economic performance and an enterprise survival and development, with the development of production technology, traditional manufacturing technology is gradually not
Adapt to the requirement produced now.Traditional crankshaft-link rod face milling is first label positioning, uses an end of crankshaft-link rod
On the basis of face, process another side, then on the basis of machined surface, process tape label point face, commonly used equipment be circular disc milling machine and
Double-station clamp, machining accuracy depend on the technology and experience of operator, and need artificial loading discharging and to processing
At crank connecting link test, which is processed as guaranteeing that processing dimension needs multiple milling, and time loss is big, especially mills
When cutting the first face, since blank forges in material positioning surface system, protrusion is more, the phenomenon that magnechuck is adsorbed loosely often occurs, holds
Easily there is part obscission from sucker, causes the accident
Chinese patent CN203092271U discloses a kind of connecting rod Double End milling system, including charging motor, charging are slided
Road, head sprocket, milling mechanism, discharging sprocket wheel, discharge runner, hydraulic device and master controller, the charging motor are set to institute
The input end of charging slideway is stated, the head sprocket is located between the outlet end and milling mechanism of the charging slideway, and described first
Milling head is connect with the shaft of the first motor, and second milling head is connect with the shaft of second motor, and described
One milling head and the second milling head are located at the two sides of the head sprocket, the discharging sprocket wheel be set to the milling mechanism with
Between the discharge runner, the feed end of the discharge runner is provided with discharging cylinder.Using motor driven automatic charging, sprocket wheel
Connecting rod is sent to bistrique automatically while carrying out two-sided processing by mechanism, and milling is once completed in closed system, effectively reduces work
The sequence time raises labour productivity, thoroughly eliminates circumference mill or the slabbing problem.
The patent does not consider fixed mechanism when milling, workpiece in a device milling when be easy to jump because of vibration
Machining position out, thus equipment is damaged, and the vibration of workpiece can also adversely affect machining accuracy when processing, and
Crank connecting link belongs to casting or forge piece, and milling face is very deep, only is not enough to mill the Double End of crank connecting link by milling head
It cuts, is unable to reach the working depth of requirement.
