Description
Technical field
The utility model relates to a kind of for the conforming system of processing bulk temperature of part processing maintenance element precision in enormous quantities control structure.
Background technology
At for the production of the car of CVT automatic gear-box driving wheel and follower high accuracy axle sleeve class (high hardness material) part, the requirement of mill Compound Machining, lathe can in a clamping, realize male cone (strobilus masculinus), end face, internal diameter and in alley efficiently, the Compound Machining of the continuous turning of high accuracy, grinding.For similar high-speed and high-efficiency machining tool, the mismachining tolerance that common thermal deformation causes can account for 30% to 70% of global error, and requiring the dimensional uniformity tolerance less than 4 μ m in the processing of the contour precision axis cover parts of CVT automatic gear-box driving wheel and follower, other factors almost is close with the dimensional uniformity franchise of part processing as: the error that the repetition clamping accuracy of the repetitive positioning accuracy of lathe axis servomotor, anchor clamps etc. is brought.So how the Control Thermal Deformation of whole system of processing just there is very important meaning to minimum.
The utility model content
The utility model is the temperature control structure that purpose is to provide a kind of high speed lathing and grinding combined machining machine tool, suppress the formation of the big gradient temperature difference thermal field of machining area in the processing continuously in efficient, high accuracy, and controlled a kind of new construction of the thermal deformation of lathe integral body in the process as much as possible.
The technical scheme that the utility model provides, a kind of temperature control structure of high-speed precision digital control lathing and grinding combined machining machine tool comprises the motor that cools off lathe and closed water-cooling system and the open spray system of bearing,
Closed water-cooling system, comprise: conical surface grinding spindle motor and bearing water cooling plant, internal diameter grinding spindle motor and bearing water cooling plant, alley grinding motor water cooling plant, linear electric motors water cooling plant, work spindle motor and bearing water cooling plant, servomotor water cooling plant, each bar path of closed water-cooling system is connected with the magnetic valve of independent its break-make of control, and is connected with the flow sensor that flow monitoring and warning are provided;
Open spray system, comprise: conical surface grinding spray equipment, internal diameter grinding spray equipment, work spindle spray equipment, alley grinding spray equipment, work spindle center spray equipment, hard turning spray equipment and lathe bed spray equipment, said apparatus is interconnected to constitute by pipeline and oil pump, each bar channel setting electric-controlled type switch of open spray system.
Above-mentioned closed water-cooling system and open spray system acting in conjunction, set up system of processing bulk temperature control structure, nearly all main pyrotoxin in the machine cut, as main shaft inner electric machine, linear electric motors, servomotor and high-speed spindle bearing etc., all pass through closed water-cooling pattern cooling; Open spray system has guaranteed all process steps cuts heat generating spot in process cooling, has also realized the spray cooling of important spare part in the process.The mode that adopts the cooling of sealing cooling device and open fountain to combine, realized the cooling of each pyrotoxin of machining area and the high accuracy cooling of critical component, not only make lathe in process, be subjected to externally temperature influence less, guaranteed the stability of the temperature of machining area simultaneously.Set up system of processing bulk temperature control structure, form high constant system of processing temperature field.
