The invention provides a kind of bias for setting eccentric top tip structure that can reduce labour intensity when processing eccentric shaft
Axis processing machine, solves the inefficiency labour intensity existing to the processing of eccentric shaft to realize lathe by arranging eccentric block
Low problem.
Above technical problem is solved by following technical proposal：A kind of eccentric shaft processing for setting eccentric top tip structure
Machine, including frame, one end of the frame is provided with machine tool chief axis, the other end and is provided with tailstock tool, it is characterised in that also include partially
Heart top tip structure, the bias top tip structure include the mohs bush linked together with the tailstock tool, are rotatably connected on
Eccentric block set, the eccentric bushing being connected in eccentric block set on mohs bush and bias be connected to top on eccentric bushing,
The top axis is parallel with the pivot center of eccentric block set.Eccentric shaft one end to be processed is solid with machine tool chief axis during use
Be scheduled on together, the other end is fixed by top heading on.Because eccentric top tip structure is directly installed on tail stock,
Workman only has the weight of product when taking product, labour intensity is relative to be mitigated, as long as while clamped one time centering, bias is top to be
360 degree are freely turned round, and it can reduce the clamping time, improve operating efficiency with automatic capturing.

Referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, during use, the liquid such as filling oil in the first oil pocket 915 and the second oil pocket 916.Every
Shake seat 9 is supported on ground by support base 93.When road shocks are subject to and cause damping spring 92 to shrink, damping spring 92 drives
Piston bar 913 drives that first piston 912 is moved and so that first the first oil pocket of oil pocket 915 reduces, the first oil pocket 915 reduces drive
Dynamic oil flows to the second oil pocket 916 through intercommunicating pore 941 from the first oil pocket 915, the flow direction of oil is detected by velocity sensor 96, speed
Degree sensor 96 controls 951 dead electricity of electromagnet by control system so that electromagnetic force adhesive mechanism 95 is lost to the first work
Plug 912 and the fixation of second piston 914（I.e. first piston 912 and second piston 914 can produce relative movement）, oil stream
Door-plate 942 is pushed open when crossing intercommunicating pore 941 so that oil flows through intercommunicating pore 941 and leads directly to and enter the second oil pocket 916（That is door-plate 942
Damping action is not produced to oil）, it is achieved thereby that damping action is less being obstructed namely spring without causing damping spring to shrink
Can shrink in time and reduce spring contraction stroke and jolt, spring contraction stroke terminate after in the presence of door-plate resetting-mechanism 97
（I.e. due to door-plate keep down inclination and density more than oil）And rotate automatically and close, door-plate 942 is stopped again in intercommunicating pore 941
Interior.Then the elongation of damping spring 92 resets and releases energy, and the result of elongation causes damping oil cylinder cylinder body 911 and first piston
912 generation disengaging movements cause that the second oil pocket 916 reduces and the first oil pocket 915 becomes big so that oil is through intercommunicating pore 941 from the second oil
Chamber 916 flows to the first oil pocket 915, the flow direction of oil and is detected by velocity sensor 96, and velocity sensor 96 passes through control system
Control electromagnet 951 electric, electromagnet 951 produces magnetic force so that electromagnetic force adhesive mechanism 95 is by first piston 912 and the
Two pistons 914 are fixed and are pressed on oil, and during oily direction runner, door-plate 942 can not be open, allow oil to whole
Individual spring contraction stroke middle door-plate 942 produces frictional damping phenomenon and energy-absorbing, jolts so as to reduce spring extended travel.
The damping energy-absorbing shock absorbing process of door-plate is：Oil flows through main damp channel, a damp channel and damper rod and rocks and will shake
Energy is changed into heat energy and consumes.When being not enough to promote blind hole to deform if vibration is less, now only have rocking for oil,
When oil is rocked, damper rod is produced and is rocked and energy-absorbing.
