Description

Bearing bush and tile seat structure of numerically controlled grinder

Technical Field

The utility model relates to a numerically control grinder field, concretely relates to numerically control grinder's support tile seat structure.

Background

The numerical control grinding machine is responsible for grinding tasks of various rollers, the grinding precision and the grinding surface quality of the rollers directly influence the surface quality of a rolled plate, and higher requirements must be provided for roller grinding in order to ensure the surface quality of the rolled plate and the requirements on roller shape control of the rollers. The surfaces of four supporting shoes of a bracket used by the equipment are arc-shaped, the contact area of the four supporting shoes and a roll neck of a roll is small, so that the supporting shoe lubricating oil is difficult to gather on the surfaces of the supporting shoes, if the flow of the lubricating oil is small, an oil film cannot be fully formed between the roll necks, the friction force is increased, and the roll cannot be driven to rotate.

When the roller rotates at a high speed during grinding, a large amount of heat can be generated due to poor lubrication between the roller shoulder and the surface of the tile seat, so that the precision of the grinding roller cannot be ensured due to the deformation of the surface of the tile seat. The tile seat needs to be frequently changed to the different kind of rolls of grinding, leads to the tile seat bottom surface to receive inhomogeneous wearing and tearing, will have partial lubricating oil to spill over from the gap during grinding roll like this, and a small amount of lubricating oil can't produce the oil film between roller shoulder and tile seat surface, just also does not have good lubricated effect yet, can cause the grinding efficiency, the grinding quality of damage and influence roll to the head of a bed transmission system of grinding machine. For example, after the bearing shoe is worn and deformed, poor grinding roundness can cause unstable operation of the rolling mill, uneven thickness, wavy bending and convex-concave edges can be generated during rolling, the product quality is seriously influenced, the service life of parts such as the rolling mill, a bearing and the like can be shortened, and the normal operation of production cannot be ensured.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a numerical control grinding machine's support tile seat structure.

The technical scheme of the utility model as follows:

the utility model provides a numerical control grinder's support tile seat structure, includes base member, lubricated oil duct and annular seal:

the center of the upper end face of the base body is provided with an annular positioning key groove and a bolt hole for fixing a positioning key, and four corners of the upper end face of the base body are respectively provided with a bolt hole for fixing a bearing shoe;

a cavity is formed in the base body, a blind hole a is formed above the cavity, an oil inlet hole is formed in the blind hole a, a lubricating oil pipeline is mounted in the cavity, and the oil inlet hole is connected and communicated with the lubricating oil pipeline;

an annular groove is formed in the upper end face of the base body around the oil inlet hole, and an annular seal is arranged in the annular groove;

and a blind hole b is formed below the tail part of the cavity and is used for connecting a lubricating oil pipeline of the bearing tile body.

The preferable scheme of the tile supporting seat structure of the numerical control grinding machine is that the base body and the tile supporting body are of an integrated structure.

The utility model has the advantages that:

(1) after the supporting tile is arranged on a bracket of the numerically controlled grinder for use, the arrangement of the annular seal can avoid the overflow of lubricating oil from the periphery of the oil inlet hole;

(2) the current support tile seat structure of contrast, the utility model discloses prolonged the life cycle of tile seat, improved the grinding precision of roll, the roll grinding volume that significantly reduces with need regrinding the number of times to improve grinding machine efficiency, reduce emery wheel consumption and oil consumption, guarantee that production goes on smoothly.
