Description
Technical field
The present invention relates to the safeguarding mechanism field in the machinery, relate in particular to a kind of being applied in and have the safeguarding mechanism of lock function voluntarily on the hydraulic press.
Background technique
In existing hydraulic press, generally adopt double shackle is installed on upper beam, single hanger is installed on the moved cross beam, need hold moved cross beam and place restrictions on it when descending, with the moved cross beam backhaul to holding the position, use then to hold bar and run through double shackle and single hanger, hold between bar, double shackle and single hanger three the formation structure that is fastened and placed restrictions on single hanger descending promptly to have limited moved cross beam descending, guarantee the regional work below moved cross beam of personal security.Insert or withdraw from double shackle and will realize holding bar, just must dispose corresponding mechanism controls and hold the bar motion.
Have air pressure, two kinds of modes of hydraulic pressure to control in the prior art and hold the bar motion, air pressure control is subjected to the air pump condition restriction, and limited coverage area, applicability are not strong; And liquid presses piston pole control holds bar this structure of moving and in industry generally uses, but the problem that has poor reliability, hydraulic type safety locking mechanism promptly holds bar from the power source to the executive component, the transmission of power circuit is long, and is middle through duct board, hydraulicdirectional control valve, reduction valve, adapter, all too many levels of pipe joint, the leakage of oil of arbitrary place, all can make and hold bar play out of control, the cost height, complex structure, bulky.
Also there is the problem of poor stability in some hydraulic presses at present; as disclosed a kind of safety cock among the patent CN200810194499.9; this safety cock is used for the slide block on the hydraulic press is tied down; it is the moved cross beam of above-mentioned indication; roughly the structure with existing hydraulic press safeguarding mechanism is identical in the disclosed technical characteristics of this patent; different is to be provided with a pair of V-shaped groove in the both sides of the single hanger that connects slide block; when making the hydraulic press overload; farthest reduced the damaged condition of equipment, the miscellaneous part of protection except that single hanger is not damaged.Though this is rational in infrastructure, can reduce the damaged condition of equipment, but also brought a comparatively serious safety problem simultaneously, on single hanger V-shaped groove is set, must reduce the maximum stress that this place can be born, therefore single hanger is easy to fracture, and this is absolutely unsafe to the operator under hydraulic press, causes security incident easily.
Summary of the invention
Problem to be solved by this invention is exactly the shortcoming at prior art, and a kind of safeguarding mechanism of simple in structure, hydraulic press that cost is low is provided, and working stability is reliable, and is easy to assembly, and can better protect equipment miscellaneous part and operator's safety.
In order to solve the problems of the technologies described above, the present invention has adopted following technological scheme: a kind of safeguarding mechanism of hydraulic press, comprise the double shackle weldment that is arranged on the upper beam, the double shackle weldment is welded by two upper ear plates that are parallel to each other that are fixed on the base plate on the upper beam and be located on the base plate, between two upper ear plates, be provided with lower ear plate, lower ear plate is fixed on the moved cross beam, be equipped with on upper ear plate and the lower ear plate and hold the hole, it is characterized in that: the outer side surface of an otic placode is connected with locking mechanism therein, this locking mechanism comprises and holds bar, be socketed in the stroke guide pipe and the driving that hold on the bar periphery and hold the motor that bar moves, hold the bar slip and run in the guide the stroke guide pipe, upper ear plate holds the hole and lower ear plate holds in the hole, makes lower ear plate be in the state that is held the bar blocking or do not held the bar blocking in the slip that holds bar.
As improved, an end of stroke guide pipe is fixed therein on the outer side surface of a upper ear plate, and stroke guide pipe and hold the hole, hold concentric setting between the bar makes the slip that holds bar more smooth and easy, improves mechanism stability and reliability.
As preferably, be provided with some deep floors between the outside tube wall of described stroke guide pipe and the outer side surface of otic placode, increase the bearing strength of stroke guide pipe.
As improved, described motor is a linear type gear reduction motor, motor is provided with the tooth bar with the interlock of motor internal gear, tooth bar is connected by draw-in groove mechanism with described holding between bar, the glide direction that holds bar be consistent with the movement locus of tooth bar and with vertical setting of installation end face of described motor.
As preferably, described draw-in groove mechanism comprises and is located at the T-slot that holds bar one termination and is located at the T shape dop that coincide with T-slot on the tooth bar that T shape dop is plugged in the T-slot that holds bar.By the setting of this draw-in groove mechanism, make tooth bar with hold bar and directly be connected, need not the middle transition driving mechanism, simplify the structure, connect and can not get loose, more reliable, reduce cost, and transmission conversion efficiency height.
As preferably, on the stroke guide pipe, be provided with automatic spacing mechanism, comprise and be located at the stroke guide pipe away from upper ear plate one termination and the pipe fitting that connects with the stroke guide pipe, the bottom of pipe fitting is provided with first limit switch, also be provided with switch bracket on the pipe fitting, switch bracket is provided with second limit switch; Be provided with the detecting body that triggers second limit switch at tooth bar one end, tooth bar with hold the end that bar is connected and trigger described first limit switch to hold bar.
Advantage of the present invention has: the composition that simplifies the internal structure of an organization, and by linear type gear reduction driven by motor tooth bar, and directly connection holds bar, no middle transition link, connection can not get loose, and is more reliable, makes total become simpler, small and exquisite, reduced design cost; Stroke guide pipe and hold the hole, hold concentric setting between the bar makes the slip that holds bar more smooth and easy, improves mechanism stability and reliability; Tooth bar can move left and right when motor does not start, and therefore holding the bar position can be not out of control, work safety, and good stability can better be protected equipment miscellaneous part and operator's safety.
