The specific embodiment
The utility model embodiment provides a kind of regulating shaft locking device, to realize regulating the quick locking of main shaft.
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, the sectional structure schematic diagram of the regulating shaft locking device that Fig. 1 provides for the utility model embodiment.
The regulating shaft locking device that the utility model provides, be used for double-roll crusher, comprise the locking plate 1 on the adjusting main shaft 5 that is fixed on double-roll crusher and be fixed on locking device 3 on the shell 4 of double-roll crusher, have locking hole 11 on the locking plate 1, locking device 3 has the locking pin 31 that can be inserted in the locking hole 11.
During use, to regulate main shaft 5 lockings if desired, so only the locking pin 31 on the locking device 3 need be inserted in the locking hole 11, locking plate 1 just can not rotate, the adjusting main shaft 5 of fixedlying connected with locking plate 1 just can not rotate yet so, thereby realizes regulating the quick locking of main shaft 5, has saved the time, reduced labor intensity, convenient and swift.
Simultaneously, regulating main shaft 5 if desired rotates, so only locking pin 31 need be extracted from locking hole 11, locking plate 1 just can rotate, regulate main shaft 5 so and also just can rotate, thereby also can realize regulating unclamping fast of main shaft 5, saved the time, reduced labor intensity, convenient and swift.
Concrete, above-mentioned regulating shaft locking device also comprises end cap 2, and end cap 2 is fixed on the shell 4 of double-roll crusher, has cavity between end cap 2 and the shell 4, accommodates locking plate 1 in the cavity, and locking device 3 is fixed on the end cap 2.Thereby make locking plate 1 obtain certain protection, prolong the service life of locking plate 1.
Please refer to Fig. 2, the structural representation of the locking plate that Fig. 2 provides for the utility model embodiment.Concrete, locking hole 11 is the profile of tooth breach that is positioned at the circumference side of locking plate 1.Locking pin 31 both can be inserted into the locking hole 11 from the direction of the periphery of locking plate 1 so, can be inserted into the locking hole 11 from the direction of the circumference side of locking plate 1 again, use flexibly, the path that can directly be inserted in the locking hole 11 is more, very convenient.
So, when locking device 3 is positioned on the periphery of end cap 2, please refer to Fig. 4, the another kind of specific embodiment structural representation of the regulating shaft locking device that Fig. 4 provides for the utility model embodiment, just can be good at finishing the insertion locking action, certainly, the length of locking device 3 can not be long, to avoid interference the rotation of turning handle 6, and when locking device 3 is positioned on the circumference side of end cap 2, be provided with turning handle 6 if regulate main shaft 5, can avoid the slewing area of turning handle 5 in the time of so just can making locking device 3 work, prevent owing to the rotation of turning handle 6 use to locking device 3 brings inconvenience.
Concrete, locking hole 11 is that square or circular, square locking hole 11 is swift in response, but because locking process fierceness, service life is shorter, and circular locking hole 11 locking processes are relatively releived, but service life is longer, and the utility model is not done concrete restriction to the shape of locking hole.
Please refer to Fig. 3 and Fig. 4, the structural representation of the locking device that the sectional structure schematic diagram of the locking device that Fig. 3 provides for the utility model embodiment, Fig. 4 provide for the utility model embodiment.Concrete, locking device comprises slide cartridge 32, locking pin 31 is arranged in the slide cartridge 32, slide cartridge 32 is provided with ladder hole, ladder hole comprises first through hole that is arranged in order, second through hole and third through-hole, wherein, the cross-sectional area of second through hole is greater than first through hole and third through-hole, first end of locking pin 31 is provided with first boss 37, the cross-sectional area of first boss 37 is greater than first through hole, be provided with the spring 33 of compression between the ladder platform of first boss 37 and second through hole and third through-hole, second end of locking pin 31 is provided with second boss 35 along the circumferencial direction of self, the outer wall of third through-hole is provided with self-locking body 34, and self-locking body 34 is provided with the groove 36 that holds second boss 35.
Wherein, the cross-sectional area of second through hole is greater than first through hole and third through-hole, to realize that spring 33 can compressing in second through hole, first boss 37 is arranged on the locking pin 31, on first boss, the 37 compressed springs 33 ladder platform that is pressed in first through hole and second through hole tightly, at this moment, locking pin 31 is inserted in the locking hole 11, regulating main shaft 5 can not rotate, in this simultaneously, second boss 35 on the locking pin 31 is in the groove 36 on self-locking body 34, when locking pin 31 need be extracted, second boss 35 is extracted from groove 36, and reverse an angle, make second boss 35 not in groove 36, but on the normal outer wall of self-locking body 34, second boss 35 is stuck on the self-locking body 34 so, can't go down, locking pin 31 also just has been pulled out so, when needs use locking pin 31 to be inserted in the locking hole 11, as long as second boss 35 is put in the groove 36, so under the active force of the spring 33 that compresses, locking pin 31 just is inserted in the locking hole 11 automatically, belongs to automanual locking device, uses more convenient.
Concrete, groove 36 is that the center of circle is 90 ° of distributions with the axle center of third through-hole.Prevent when a plurality of groove 36 is set, because hypotelorism between each groove 36 when second boss 35 is run into, is slipped in the groove 36 too easily.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
