Abstract
The utility model discloses a ratchet type emergency braking device which belongs to the field of a sleeve clutch pressing machine and includes a ram, a pallet, a reset mechanism, a drawbar and an electromagnet. The ram has a through cavity which forms a slideway and the pallet is positioned in the slideway; the reset mechanism includes a reset lever and a return spring; one end of the reset lever touches the pallet and the other end of the reset lever is an axial free end; one end of the return spring supports on the reset lever and the other end supports on a bracket which is relatively fixed on the ram; one end of the drawbar is connected with the pallet through a pin, the other end of the drawbar is connected with a armature in the electromagnet; the pallet is an inclined pallet and the back of the pallet forms an angle with the slideway; a shock absorption mechanism is arranged on the ram and the working face of the shock absorption mechanism touches the back of the pallet. The utility model can make the operating key in the clutch of the pressing machine fall accurately; at the same time, the service lives of the control parts and the electromagnet are prolonged and the reliability and the safety is improved.
Description
Technical field
The executor of ratchet-type emergency braking apparatus belongs to the rigid clutch pressing machine field.
Background technology
In the prior art, some rigid clutch pressing machine adopts a kind of executor of ratchet-type emergency braking apparatus, have one to run through chute of cavity formation in the ram, ratchet is arranged in the chute of ram and matches with chute, resetting-mechanism comprises release link and back-moving spring, release link withstands on the ratchet, back-moving spring one end is supported on the release link, the other end be supported on the relatively-stationary support of ram on, draw bar one end is connected by pin with ratchet, the other end links to each other with armature in the electromagnet, ratchet is straight ratchet, when the electromagnet dead electricity, under the effect of resetting-mechanism, straight ratchet engages with ratchet, whole clutch components will stop operating, but the rotary inertia of clutch is very big, can't eliminate moment, and this moment, straight ratchet can not be swung backward, rotary inertia will focus on the whole executor parts, the easy like this damage that causes the executor parts, it is unclear that excessive recoil strength can make the job key in the clutch components break away from, and when electromagnet gets when electric, the electromagnetically-operated power of straight ratchet is bigger, the service life of electromagnet be can shorten so again, thereby the reliability and the security of lathe influenced.
Summary of the invention
The purpose of this utility model provides a kind of technical scheme of executor of ratchet-type emergency braking apparatus, job key in the clutch components is accurately broken away from, make the long service life of control member and electromagnet simultaneously, not fragile, thus its reliability and security are increased.
The purpose of this utility model is to realize like this, a kind of executor of ratchet-type emergency braking apparatus, comprise ram, ratchet, resetting-mechanism, draw bar, electromagnet, have one to run through chute of cavity formation in the ram, described ratchet is arranged in the chute of ram, described resetting-mechanism comprises release link and back-moving spring, release link one end withstands ratchet, the release link other end is axial free end, described back-moving spring one end is supported on the release link, the other end be supported on the relatively-stationary support of ram on, described draw bar one end is connected by pin with ratchet, the other end links to each other with armature in the electromagnet, it is characterized by: described ratchet is oblique ratchet, the ratchet pawl back of the body and chute shape at an angle, ram is provided with a damping, the working face of described damping withstands the ratchet pawl back of the body.
When the electromagnet dead electricity, ratchet engages with ratchet, and ratchet can be swung to the opposite side of working face, thereby the rotary inertia on the clutch is offset by damping, with the protection control member; Simultaneously, can make the job key in the clutch break away from good, when electromagnet gets, ratchet is to draw bar one lateral movement, because the ratchet pawl back of the body can hightail with damping, the electromagnetically-operated power of ratchet disengaging ratchet is less relatively, can make the long service life of control member and electromagnet, not fragile, thus its reliability and security are increased.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation.
Wherein, 1 straight ratchet, 2 rams, 3 release links, 4 draw bars, 5 electromagnet, 6 pins, 7 oblique ratchets, 8 apical axis, 9 pressing plates, 10 buffer springs, 11 back-moving springs, the 12 ratchet pawls back of the body.
The specific embodiment
A kind of executor of ratchet-type emergency braking apparatus, comprise ram 2, oblique ratchet 7, resetting-mechanism, draw bar 4, electromagnet 5, have one to run through chute of cavity formation in the described ram, described oblique ratchet 7 is arranged in the chute of ram 2, described resetting-mechanism comprises release link 3 and back-moving spring 11, release link 3 one ends withstand ratchet, the release link other end is axial free end, described back-moving spring 11 1 ends are supported on the release link 3, the other end be supported on ram 2 relatively-stationary supports on, described draw bar 4 one ends and oblique ratchet 7 are connected by pin, the other end links to each other with armature in the electromagnet 5, the described oblique ratchet pawl back of the body 12 and chute shape are at an angle, ram is provided with a damping, described damping comprises pressing plate 9, apical axis 8, buffer spring 10, described pressing plate 9 and ram 2 relative fixed, described apical axis 8 is provided with a boss, apical axis vertically passes pressing plate 9 and ram 2, one end withstands the ratchet pawl back of the body 12, described buffer spring 10 is enclosed within on the apical axis, one end withstands pressing plate 9, and the other end withstands on the boss on the apical axis 8.
When the electromagnet dead electricity; under the effect of resetting-mechanism; tiltedly ratchet 7 stretches out ram 2, engage with ratchet, and under the drive of ratchet inertia; carrying on the back 12 1 sides to the ratchet pawl rotates; and the rotary inertia on the ratchet passed to apical axis 8, and further offset by buffer spring 11, thereby control member protected; simultaneously, can make the job key in the clutch break away from good.When electromagnet gets electricly, ratchet is to draw bar one lateral movement, because the ratchet pawl back of the body 12 can hightail with damping, tiltedly ratchet 7 is relative less with the electromagnetically-operated power of ratchet disengaging.
