Full-automatic digital control roll grinder backup roll belt box grinding device

Abstract

The invention discloses a full-automatic digital control roll grinder backup roll belt box grinding device, comprising an installation precision regulating device, an oil supplying device and an oil temperature controlling device, wherein the installation precision regulating device comprises a bearing box pushing cylinder, limit blocks, an inching device and a clamping plate, the bearing box pushing cylinder and the limit blocks are arranged on the box seat and used for locating the position of the bearing box relative to the box seat, the clamping plate is used for driving the box seat to slide in a radial direction relative to a bed body of a workpiece, and the inching device and the lamping plate are used for regulating the radial position of the box seat at one end of the bed body of the workpiece so as to parallel a space axial line between the two box seats with the axial line of a grinding wheel, thereby ensuring grinding precision; the oil temperature controlling device comprises a temperature sensor and an oil temperature controller, which is used for ensuring that the temperature of the supplied oil in the oil supplying device is proper; and the oil supplying device comprises an oil inlet pipeline, a cylinder and an oil outlet pipeline with an overflow valve and a throttle valve, which is used for supplying the oil meeting the requirements of temperature, oil pressure and flow to a bearing box so as to ensure that a oil film bearing forms an effective dynamic pressure, thereby effectively avoiding hidden troubles of damaging a bearing and ensuring grinding efficiency. In all, the invention ensures grinding, and can be convenient and reliable in use.

Description

technical field [0001] The invention relates to a full-automatic numerical control roll grinder, in particular to a full-automatic numerical control roll grinder support roll belt box grinding device. Background technique [0002] At present, when the roll grinder is grinding the back-up roll, the bearing housing of the back-up roll is usually unloaded, and the static pressure steady rest is used for grinding, and the bearing housing is reinstalled for use after the grinding process is completed. The weight of the bearing box of the backup roll is usually more than 20 tons. The disassembly process is cumbersome and time-consuming and is easy to damage the bearing box of the backup roll, which leads to an increase in the processing cost of the rolling line of the steel mill. During the grinding process, grinding the support roll with a bearing box can solve the above problems well. However, the roll bearing box must be filled with oil that meets the oil pressure, flow and tem...

Problems solved by technology

The weight of the bearing box of the backup roll is usually more than 20 tons. The disassembly process is cumbersome and time-consuming, and it is easy to damage the bearing box of the backup roll, which leads to an increase in the processing cost of the rolling line of the steel mill.

During the grinding process, grinding the support roll with a bearing box can solve the above problems well. However, the roll bearing box must be filled with oil that meets the oil pressure, flow and temperature requirements to effectively form an oil film bearing. However, due to When the roll speed is too low during grinding, the oil film bearing of the roll cannot effectively form dynamic pressure, which may cause hidden dangers of bearing damage; secondly, the bearing box must be used for positioning and grinding support when grinding with a box, due to box seat errors and oil film bearings The gap may cause the problem of reduced grinding accuracy and grinding efficiency
