Description
Technical field
The present invention relates to a kind of cam controller with axial mechanical position limitation, be particularly useful for the punching machine meeting GB27607-2011 " punching machine safety specifications ".
Background technology
Cam controller is the important component part of punching machine electrical control system.In a duty cycle of punching machine, the action of main and auxiliaries (subsidiary engine of particularly controlled pressure machine slide block action) each operating mechanism has strict logical relation, comprises the order of action and the time shared by action.The method of work for the treatment of mechanism logical relation, normally distributes crankshaft rotating one week 360 °, makes the working cycle diagram of punching machine, controlled the action of each operating mechanism.Cam controller is exactly the actuator distributed crankshaft rotation angle.Cam controller is installed on the axle that rotates with crankshaft-synchronous, along with the rotation of bent axle, cam controller sends corresponding signal, sends instruction after electric-control system Received signal strength to each operating mechanism, operating mechanism produces the action of regulation successively, completes a duty cycle of punching machine.
Existing cam controller is made up of camshaft, cabinet and switch module.Camshaft is provided with some groups of adjustable cams, often organizes adjustable cam and be made up of stage clip, cam and axle sleeve.Axle sleeve is arranged on camshaft, and cam is engaged with axle sleeve by end face gear ring, and stage clip is arranged in the space between two groups of adjustable cams.When needs adjustment angle, only need cam axially to pull open exit gear ring engagement after rotate to the angle of needs after push again and engage, this angular adjustment can be carried out within the scope of 360 °.
Within existing adjustable mechanical cam controller can ensure that the maximum rotation regulated quantity of its adjustable interior and exterior cam blade is limited in certain angle, generally within 60 °.This adjustable cam controller in actual applications, is all after first installing cam, then carries out the adjustment of angle as required; But due to the adjustable limited allowance of existing adjustable cam controller, easily cause the cam when applying not reach required angular range.
On the other hand, existing cam controller can produce vibration when lathe works, and easily causes producing between the cam in cam controller and axle sleeve sliding, formation control angular deviation; And when travel switch contact and the cam outboard friction of cam controller inside, cam by frictional force impact also can relatively axle sleeve end face gear ring produce slip, formation control angular deviation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of cam controller with axial mechanical position limitation is provided, improve the reliability of cam controller on the one hand, prevent the slip of cam; On the other hand the rotation regulated quantity of cam can be controlled.
According to technical scheme provided by the invention, the described cam controller with axial mechanical position limitation, comprises controller case, is located at camshaft in controller case and switch module; Described camshaft is installed multiple cams assembly, between adjacent cam pack, be provided with stage clip; Described cam pack comprises the axle sleeve be set on camshaft, be set in external cam on axle sleeve and cam ring, the both sides end face of cam ring arranges gear ring, one side end face of external cam is provided with gear ring, one side end face of axle sleeve is provided with gear ring, the side end face gear ring of cam ring engages with the end face gear ring of axle sleeve, and the opposite side end face gear ring of cam ring engages with the end face gear ring of external cam; It is characterized in that: inside the end face gear ring of described external cam, be provided with the first deep-slotted chip breaker, outside the side end face gear ring of cam ring, be provided with the second deep-slotted chip breaker, inside the opposite side end face gear ring of cam ring, be provided with cannelure; In the cannelure of described cam ring, arrange the first guide vane end stop, arrange spacer pin in the side of the first guide vane end stop, this spacer pin is arranged in the first deep-slotted chip breaker of external cam; Arrange the second guide vane end stop at described sleeve outer surface, one end of the second guide vane end stop is large end, and the other end is small end, and small end is arranged in the second deep-slotted chip breaker of cam ring.
Described first guide vane end stop is fixed by connector and cam ring.
Described second guide vane end stop is fixed by connector and axle sleeve.
Described first guide vane end stop ringwise, the outer circumference surface of the first guide vane end stop arranges adjustment gear.
Described switch module comprises multiple switch being arranged on camshaft side, often organizes cam pack correspondence and installs a switch.
The lower surface of the large end of described second guide vane end stop is the arc surface matched with sleeve outer surface.
The present invention can effectively avoid because regulating mistake or surprisingly causing security incident, the Measures compare of this mechanical position limitation is flexible, avoid because each cam work angle scope is different, the complex situations that the relative position of the cannelure of its interior and exterior cam is different, alleviate its mach intensity, improve efficiency.
