Description
Technical field
The present invention relates to the parts on a kind of numerical control (CNC) spring machine, particularly relate to diameter changing mechanism of numerical control pressure spring machine.
Background technology
At present, the diameter changing mechanism of numerical control pressure spring machine of prior art is controlled the external diameter of made spring nothing more than mechanical means such as relying on gear drive, lever transmission, cam drive, manual adjustments.This mechanism is complex structure not only, and noise is big, and transmission link is many, and the transmission accumulated error is big, and can not give full play to the digital control function of computer, influences the product precision, and manufacturing cost is big.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, break through the traditional habit thinking, a kind of unprecedented diameter changing mechanism of numerical control pressure spring machine design is provided, can simplify frame for movement, reduce the debugging technique difficulty, noise is low, the spring accuracy of manufacture is improved in the power consumptive province.
The technical solution adopted in the present invention is: diameter changing mechanism of numerical control pressure spring machine comprises servomotor, ball-screw, reducing base, reducing base fixed screw, screw slide block, hold-down support, reducing base pressing plate, knife rest, top spring pin, top spring key seat, front wallboard, front wallboard deep-slotted chip breaker.
Servomotor is fixedly mounted on the front wallboard, and its rotating shaft is fixedlyed connected with the afterbody of ball-screw, and ball-screw is the energy forward or reverse under the driving of servomotor rotating shaft, or fast the commentaries on classics or slow-speed.
Ball-screw and screw slide block are matched in clearance, and ball-screw can rotate in the screw slide block, and the screw slide block can move on ball-screw.When ball-screw just changes, promote the reach of screw slide block; When ball-screw reverses, promote to move behind the screw slide block.
Screw slide block and reducing base are matched in clearance, and the screw slide block can move forward and backward on the reducing base; And between the reducing base pressing plate is matched in clearance, and relative slip can be arranged.The reducing base pressing plate of fixing on the reducing base is used for controlling glade plane space between screw slide block and the reducing base.Use with the passing of time, when screw slide block and reducing base generation wearing and tearing, can change simple reducing base pressing plate and readjust precision, make complicated, that cost is expensive screw slide block or reducing base and needn't change.
Fixedly mounting knife rest on the screw slide block, top spring key seat and top spring pin are being installed on the knife rest.When the screw slide block moved forward and backward under ball-screw drives, the top spring pin that is fixed on the screw slide block just withstood or leaves spring steel wire, dropped into the reducing operation of making spring.
Be provided with the twice deep-slotted chip breaker on the pressure spring machine front wallboard, can hold reducing base fixed screw and in deep-slotted chip breaker, slide or lock, thereby adjust the action direction of diameter changing mechanism spring.
Upper and lower at the body front wallboard respectively is equipped with the two cover diameter changing mechanisms identical with above-mentioned parts, diameter changing mechanism was devoted oneself to work above or below manufacturing left-handed according to spring or dextrorotation required to select, affact on the steel wire in the motion, thereby reach the purpose of controlling made spring external diameter.
The invention has the beneficial effects as follows: abandoned conventional robot sections such as complicated gear drive, lever transmission, cam drive, manual adjustment, directly the servomotor by computer control drives slide block by high-precision ball-screw, control with the enhancing computer software and to simplify the control of traditional machinery, reduce operating personnel's debugging technique difficulty, really realized the human-computer dialogue of numerical control pressure spring machine, given full play to the numerical control advantage of computer, reduce the machine driving link, owing to eliminated the accumulated error that a plurality of transmissions form, thereby improved the spring accuracy of manufacture.Also has the plurality of advantages that noise is low, electricity consumption is few, fault is few, area occupied is little, debugging is simple, manufacturing cost is economized.Highly versatile of the present invention is applicable to 3 millimeters of steel wire diameter---the multiple numerical control pressure spring machine of 20 millimeters scopes.
