Description

Roller bearing seat cushion block of cold rolling machine

Technical Field

The utility model relates to the field of machinary, a fixing device of roll specifically says so.

Background

At present, in order to realize 6S management and safe and civilized production, the field is required to be neat and orderly. Because the surface of the middle roller body adopts a CVC curve shape, the middle roller bearing block needs to be hoisted to the ground in front of the roller changing vehicle after being assembled with the shaft neck and is placed up and down in pairs. Meanwhile, a cushion block is required to be placed between the bearing seats of the upper and lower rollers, so that the surface defects caused by indentation, punch mark, scraping and the like due to the contact of the roller body between the upper and lower intermediate rollers are prevented, the inspection and confirmation of the surface quality of the roller body before the roller is installed on a machine are facilitated, the plastic film package on the surface of the roller body is convenient to detach, and the field of a spare roller area is effectively utilized.

The prior art does not provide drawing of a middle roller bearing block cushion block, and a long strip batten can only be used for being cushioned between an upper bearing block and a lower bearing block during production. The intensity of the used long-strip batten is not enough, the batten is often cracked and damaged, the upper roller cannot be in a straight line with the lower roller when being hoisted by the crown block, the upper roller needs to be pushed and pulled to be aligned by operators, and potential safety hazards are caused to the operators if the upper roller is inclined. The invention aims to design a cushion block, solve the problem of skew arrangement of the upper roller and the lower roller, eliminate potential safety hazards and realize the quality safety.

Disclosure of Invention

In order to solve the technical problem, the utility model discloses a to the structure of bearing frame, design a backing plate, can effectively fix the relative position of bolster bearing housing and step to use when being fit for hoist and mount. The specific technical scheme is as follows:

a cushion block of a roller bearing seat of a cold rolling machine comprises an upper cushion plate and a lower cushion plate, wherein the upper cushion plate and the lower cushion plate are both U-shaped, and the upper cushion plate is sleeved outside a boss below the upper bearing seat and is abutted against the lower part of the upper bearing seat; the lower backing plate is sleeved outside the convex part below the lower bearing seat and is abutted against the upper part of the lower bearing seat; positioning pins are arranged in the grooves of the upper backing plate and the lower backing plate and correspond to the hoisting holes of the upper backing plate and the lower backing plate; an upper fixing part and a lower fixing part are respectively arranged on two sides of the upper backing plate and the lower backing plate, pin holes are correspondingly arranged at the upper fixing part and the lower fixing part, and a plug pin is inserted into the pin holes; the distance between the inner side of the lower backing plate groove and the side face of the lower bearing seat protruding part is smaller than the distance between the inner side of the upper backing plate groove and the side face of the upper bearing seat protruding part.

The inner sides of the opening end parts of the grooves of the upper backing plate and the lower backing plate are inclined planes.

The difference between the outer diameter of the positioning pin of the upper base plate and the inner diameter of the hoisting hole of the upper bearing seat is larger than the difference between the outer diameter of the positioning pin of the lower base plate and the inner diameter of the hoisting hole of the lower bearing seat.

The upper base plate comprises an upper support plate in the middle and upper top plates arranged at two ends of the upper support plate, and the upper support plate is of a hollow structure; the lower supporting plate comprises a middle lower supporting plate and lower top plates arranged at two ends of the lower supporting plate, and the lower supporting plate is of a hollow structure.

The utility model has the advantages that: the device has the axial and longitudinal positioning functions, prevents the upper and lower roller bearing blocks from being inclined when being placed, and is suitable for fixing the relative positions of the upper and lower roller bearing blocks during simultaneous lifting.
