A kind of sliding guide that has spring push profile of tooth pin
Technical field
The utility model belongs to a kind of steel rolling metallurgical equipment, specifically is a kind of sliding guide that has spring push profile of tooth pin.
Background technology
Guide and guards be in the continuous section rolling system before finished product and in finished product sortie rolling with rolled piece accurately guiding enter roll pass and prevent the rolled piece surface by a kind of device of scratch, its guiding accuracy is related to rolled piece quality and production safety.
The existing glide guide and guard include holder, and the guide and guard support is installed on the holder, in the guide and guard support casing is installed, delivery guide is installed in the casing, the profile of tooth pressing plate is installed on the casing, on the described guide and guard support keyhole is arranged, the keyhole epimere has internal thread, and spiral shell has bolt on the internal thread; One ring platform is arranged on the keyhole hypomere inwall, and the keyhole hypomere has a profile of tooth pin, and the profile of tooth pin has an annular lip, and the compression spring is arranged between profile of tooth pin and the bolt, and there is the flank of tooth that cooperates with the profile of tooth pressing plate described profile of tooth pin lower end.When needs are taken casing apart, earlier bolt is unclamped, but the profile of tooth pin is stuck on the profile of tooth pressing plate, be difficult to take out, influenced work.
The utility model content
The purpose of this utility model provides a kind of sliding guide that has spring push profile of tooth pin, has increased on the profile of tooth pin and has backed down spring, and when the dismounting casing, the profile of tooth pin is upspring automatically, throws off the profile of tooth pressing plate, and casing can take out from the guide and guard support fast.
The technical solution of the utility model is as follows:
A kind of sliding guide that has spring push profile of tooth pin, include holder, the guide and guard support is installed on the holder, in the guide and guard support casing is installed, delivery guide is installed in the casing, it is characterized in that being equipped with on the casing profile of tooth pressing plate, on the described guide and guard support keyhole is arranged, the keyhole epimere has internal thread, and spiral shell has bolt on the internal thread; One ring platform is arranged on the keyhole hypomere inwall, the keyhole hypomere is inserted with a profile of tooth pin, and the profile of tooth pin has an annular lip, between profile of tooth pin and the bolt extrusion spring is arranged, annular lip and and the ring platform of keyhole inwall between back down spring, there is the flank of tooth that cooperates with the profile of tooth pressing plate described profile of tooth pin lower end.
Compare with prior art, the utility model backs down spring by increasing on the profile of tooth pin, makes when the dismounting casing, and back down spring with the automatic jack-up of profile of tooth pin, profile of tooth pin and profile of tooth pressing plate are thrown off, and casing can take out fast, has saved the time, the efficient height.
