Description

Technical Field

[0001] The utility model relates to a disassembly and assembly tool for a pull rod bearing box of a section steel rolling mill, belonging to the technical field of rolling mills. Background Art

[0002] At present, there is no special tooling for laying the mill bearing box flat when repairing the profile finishing mill. It is very difficult to disassemble and assemble the mill bearing box, and the mill bearing box cannot be fixed. When removing the copper nut on the pull rod, it is very easy to deviate, causing difficulty in disassembly and assembly, resulting in rework, high labor intensity for employees, low efficiency, and easy to cause safety accidents.

[0003] The current method for disassembling and assembling the bearing box is mainly to use a general tooling platform, which is equipped with a clamping structure. However, the bottom of the rolling mill bearing box is mostly rectangular, and two clamping plates cannot be used to reliably clamp the rolling mill bearing box. Using multiple clamping plates will make the entire tooling too complicated and the operation will be more troublesome. In addition, the height adjustment structure of the existing tooling platform will also be more complicated.

[0004] Chinese utility model patent application number CN202222591525.X discloses a clamping fixture comprising a base, a movable member, and a drive assembly. The movable member comprises a first movable member and a second movable member disposed oppositely and movably connected to the base. The first movable member is formed with a first pressure block, and the second movable member is formed with a second pressure block disposed opposite the first pressure block. The drive assembly is connected to the first movable member and the second movable member, respectively, for driving the first and second movable members to move. Under the action of the drive assembly, the first and second movable members can move closer or farther away from each other, and the first and second pressure blocks move accordingly, thereby compressing and fixing the member to be fixed between the first and second pressure blocks. This clamping fixture does not have a lifting function, and the pressure plate is not suitable for clamping rolling mill bearing boxes of different heights. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems of complex structure, difficulty in disassembling and assembling rolling mill bearing boxes and low efficiency in the prior art, and to provide a tool for disassembling and assembling the tie rod bearing box of a section steel rolling mill.

[0006] The utility model is realized through the following technical solutions:

[0007] A tool for disassembling and assembling a tie rod bearing box for a section steel rolling mill comprises two sets of lower and upper shells which are sleeved together.

A lifting screw is provided which runs horizontally through the nut and the top of the lower shell, and a helical gear 1 is provided on the top of the lifting screw, which meshes with the helical gear 2.

[0008] A lifting platform is fixedly arranged between the tops of two upper shells. On both sides of the upper end of the lifting platform, a nut seat is respectively arranged. A moving lead screw passes through the nut seat, and an L-shaped clamping plate is installed at the inner end of the moving lead screw.

[0009] The lifting function of the lifting platform is realized by rotating the rotating rod, and the reliable clamping of the rolling mill bearing box is realized by rotating two moving lead screws. The operation is simple, the disassembly and assembly efficiency is high, and the overall tooling structure is simple.
