Description
Technical Field
The utility model relates to a belted steel galvanizing equipment technical field specifically is an adjustable strutting arrangement for roll bush coping.
Background
The roller and the supporting roller are important parts of a rolling mill, a lining and a roller surface of the roller and the supporting roller are easy to wear after the roller and the supporting roller are used for a certain time, in order to prolong the service life and save the cost, general surface micro defects can be used online again only by grinding through a grinding machine, when the roller or the supporting roller is ground through the existing grinding machine, a plurality of supporting devices are required to be arranged at the bottom of the roller during processing due to large diameter size and heavy weight, the existing supporting devices cannot guarantee grinding of the roller surface and the lining surface simultaneously during actual use, and the supporting position needs to be replaced when different grinding surfaces are ground, so that inconvenience is brought to processing.
Disclosure of Invention
The utility model aims at providing an adjustable support device for roll bush coping that the problem that causes inconvenience for processing is exactly that coping simultaneously coping roll surface and bush face need not be changed to the support position when solving current strutting arrangement when in-service use, coping different time, need not be guaranteed in the time of the coping.
The utility model has the following concrete scheme: the utility model provides an adjustable strutting arrangement for roll bush coping, includes the base, is equipped with two sets of climbing mechanism on the base, and two sets of climbing mechanism intersect so that support the roll along the axis of jacking direction, and detachable cushion is equipped with to every output of group climbing mechanism, and the cushion is the cambered surface with the contact surface of roll.
Two sets of climbing mechanisms include climbing mechanism A and climbing mechanism B, and wherein climbing mechanism A includes the base is equipped with the horizontally slip chamber in, the slip intracavity is equipped with the horizontally sliding voussoir, and the base top is equipped with the ejector pin chamber, and ejector pin A is equipped with in the ejector pin chamber, and ejector pin A top is equipped with the cushion, ejector pin A bottom stretch into the slip intracavity and with voussoir cooperation action, the base is located slip chamber one side and is equipped with the screw rod through the bearing, screw rod inner with voussoir threaded connection, rotatory screw rod make the voussoir translation drive ejector pin A elevating movement.
Climbing mechanism B is equipped with the sliding sleeve of slope including setting up the fixed bolster on the base on the fixed bolster, is equipped with the ejector pin B that removes along the sliding sleeve in the sliding sleeve, is equipped with on ejector pin B top the cushion, ejector pin B bottom are equipped with the internal thread, and a lead screw, lead screw and ejector pin B threaded connection are equipped with through the bearing in the sliding sleeve bottom.
Ejector pin A is 40 ~70 with vertical planar contained angle alpha, and ejector pin B is 5 ~30 with vertical planar contained angle beta.
The utility model discloses the theory of operation as follows: the height positions of the ejector rod A and the ejector rod B are adjusted through the adjusting screw rod and the screw rod during supporting, so that the diameters of different parts of the roller are adapted, the roller surface can be polished through two points for supporting, the feed distance can be adjusted after the roller surface is polished, and the liner surface can be continuously polished.
Compared with the prior art, the utility model has the following advantages: the supporting position does not need to be changed when grinding different surfaces, the processing is more convenient, and the lifting adjustment of the ejector rod can adapt to rollers and supporting rollers with different sizes.
