Description
Technical field
The utility model relates to a kind of lathe operating mechanisms, more specifically, it relates to which a kind of lathe tailstock is simply automatic
Feed limiting device.
Background technique
Lathe is the basic equipment of machining industry, and there are many lathe type, from the center lathe of low side to high-end
Numerically controlled lathe, each manufacturing enterprise select to use according to itself product requirement.Domestic a large amount of little Wei enterprises for cost consideration,
It still tends to using center lathe.Engine lathe processing object is wide, and the adjusting range of the speed of mainshaft and the amount of feeding is big, is capable of processing work
Surfaces externally and internally, end face and the internal and external threads of part, but this lathe, mainly by worker's manual operations, production efficiency is low, is suitable for single
Part, small serial production and repair and spare parts workshop.With persistently riseing for China's recruitment cost, enterprise is also compeled by situation, and not broken thinking side is set
Method is raised labour productivity, therefore many enterprises will be changed to people's multimachine, i.e., one operation with the configuration mode of previous one machine of people
Personnel plan as a whole the time, while operating multiple devices.For full-automatic lathe, a people controls multiple devices and is not difficult to accomplish, and
For the automations such as center lathe, semi-automatic lathe, the lower equipment of intelligence degree, people's multimachine often will cause this mistake of Gu
That, the case where being nervously fumbled, such as the feeding of lathe tailstock of center lathe is monitored by operator, after being fed into extreme position
Operator, which must stop in time and shift gears, makes lathe tailstock retract, otherwise lathe tailstock persistently feed not only can defective work piece,
Can also damage be also resulted in lathe itself.However, center lathe is larger to the dependence of manual control, insurance, safety etc
Configuration is often simplified, and people's multimachine is difficult to avoid the generation of some accidents in this case.The current country still has huge
Center lathe, semi-automatic lathe ownership are all replaced with the higher lathe of more advanced, the degree of automation not existing in the short time
It is real, therefore how simple and effective technological transformation is carried out to center lathe, it is allowed to adapt to new situations to need to become one urgently to solve
Project certainly.The utility model patent of Publication No. CN202438873U disclosed a kind of lathe tailstock on September 19th, 2012
Auto-feeder.It mainly solves the needs of lathe tailstock present in the prior art and is manually fed, and operates more numerous
Miscellaneous, the labor intensity of worker is larger, and is easy to produce the technical problems such as accident.The utility model includes rack, is set in rack
There is lathe transmission shaft, described lathe transmission shaft one end is connected with pinion gear by connecting shaft, and pinion gear is equipped with arresting gear,
Pinion gear is engaged with gear wheel, and for gear wheel by axis connection minor sprocket, minor sprocket is connected with big sprocket wheel by chain, in big sprocket wheel
It wears and is connected to drive rod, transmission boom end connects lathe tailstock.But the utility model not can solve lathe tailstock and be automatically fed into
The problem of being automatically stopped up to extreme position.
Utility model content
Existing machine tool automation, intelligence degree are lower, and lathe tailstock feeding, retracting relies on manual control, are
Overcome this defect, the utility model provides one kind and can limit automatically to the feeding of lathe tailstock, is conducive to improve life

Power is big, and overload capacity is strong.
As an alternative, the output end of lathe tailstock returning electrical motor is keyed an active synchronization belt wheel, and key connects on drive lead screw
A driven synchronous pulley is connect, active synchronization belt wheel passes through synchronous band connection with driven synchronous pulley.It is active synchronization belt wheel, driven same
It walks belt wheel and synchronous belt constitutes belt drive structure, make to realize transmission connection between lathe tailstock returning electrical motor and drive lead screw.Band passes
Dynamic structure structure is simple, stable drive, can buffer absorbing, and low cost, maintenance are easy.
Preferably, rack is equipped with a sliding slot, a guide rod, flexible block adaptation sliding are equipped between the both ends end wall of sliding slot
It in sliding slot and is slidably socketed on guide rod, sliding slot one is equipped with spring between end wall and flexible block, spring is also socketed in
On guide rod.Before jacking block presses flexible block, spring pushes flexible block to be biased to sliding slot one end, makes cable slack, jacking block is with vehicle
After tailstock frame is fed into extreme position, flexible block is pressed, spring force is overcome to push flexible block to the sliding slot other end, is tensed
Drag-line, and pulling force valve is pulled to make cylinder movement, push gear lever to stop the feeding of lathe tailstock.
The beneficial effects of the utility model are:
Structure is simple, and it is convenient to install additional.The utility model can carry out the transformation of convenient and high cost effectiveness to existing center lathe,
Improve the degree of automation of the feeding process of center lathe.
Improve center lathe safety in operation.After being transformed using the utility model to center lathe, it can reduce to people
The dependence of work operation, improves center lathe safety in operation, even if operator does not have found that lathe tailstock has been fed into the limit
Position need not also worry that the lathe tool on lathe tailstock is excessively fed, beyond setting processing dimension, defective work piece.
Be conducive to improve working efficiency, reduce labor intensity.After installing the utility model additional on center lathe, can effectively it advise
Keep away because of manual control production accident not as good as caused by, people's multimachine can also cope with calmly, do not easily lead to it is busy, will not be because of production
Accident spends a large amount of working hours to deal with problems arising from an accident, therefore working efficiency can be improved, and reduces labor intensity.
