Description

Technical Field

[0001] The present invention relates to the technical field of machining process equipment for large bases, and particularly to an anti-vibration milling machining positioning and clamping tooling for the base of a large block shearing machine. Background Art

[0002] A shearing machine is a mechanical device for shearing waste steel. By shearing the recycled waste steel into materials of a unified specification, the recycling of waste steel is greatly facilitated.

[0003] A typical shearing machine in the prior art is a gantry shearing machine, which includes a gantry-type frame, guide rails provided on the frame, an upper knife seat and a lower knife seat provided on the frame. The lower knife seat is fixed on the frame, and the upper knife seat is movably provided on the guide rails and can move up and down along the guide rails under the drive of a shearing oil cylinder connected to the upper knife seat. An upper shearing blade and a lower shearing blade are respectively provided on the upper knife seat and the lower knife seat. A pressing oil cylinder is also provided on the frame of the gantry shearing machine, and a material box and a pushing oil cylinder are connected beside the frame. During operation, waste steel is pre-placed in the material box, and then the pushing oil cylinder pushes the waste steel into the space between the shearing blades of the upper knife seat and the lower knife seat, and fixes it through the pressing oil cylinder. Then, under the action of the shearing oil cylinder, the upper knife seat moves downward to realize the mutual shearing of the upper shearing blade and the lower shearing blade, thereby cutting the waste steel.

[0004] Generally, the materials cut by the gantry shearing machine are relatively large in size and cannot be formed into smaller cut blocks by block shearing to facilitate subsequent recycling treatment. For this reason, a block shearing machine has been developed, and its main structure includes a material box and a block shearing component provided at the material output end of the material box. The block shearing component includes a knife seat that can move horizontally perpendicular to the material output direction, and an L-shaped cutting knife provided on the knife seat. During operation, the waste materials in the material box are pushed into the shearing space of the knife seat, and the waste materials are cut into small square cut blocks by the L-shaped cutting knife. After each small square cut block is cut, the knife seat moves a cutting distance, and then the L-shaped cutting knife is used again to cut the next small square cut block on the waste materials, so as to realize the block shearing of the waste materials in the moving direction of the knife seat; after the materials in the moving direction of the knife seat are sheared, the waste materials in the material box continue to be pushed forward, and then the L-shaped cutting knife continues to cut, so as to realize the continuous block shearing of the waste materials.

[0005] The block shearing component in the above-mentioned large block shearing machine is integrally movably arranged on the base through guide rails, and the base is made of, for example Figure 5For the shown welded structural member, the large plane on the base for installing the guide rail is completed by using a large milling equipment. Since the guide rail needs to be installed on the base of the sectional shearing machine, the machining accuracy requirements are relatively high. In the prior art, there are still the following problems in the milling of the large plane of the sectional shearing machine base: due to the large size of the base, uneven clamping force, and milling vibration and other reasons, it is easy to cause the flatness of the large plane of the base to exceed the tolerance, thus affecting the installation accuracy of the guide rail. Summary of the Invention

The five-way floating tightening component includes a floating tightening seat erected and fixed on the milling machine workbench, a top floating support cylinder arranged at the top end part of the floating tightening seat, a front side floating support cylinder arranged at the front side position of the upper part of the floating tightening seat, a rear side floating support cylinder arranged at the rear side position of the upper part of the floating tightening seat, a left side floating support cylinder arranged at the left side position of the upper part of the floating tightening seat, and a right side floating support cylinder arranged at the right side position of the upper part of the floating tightening seat.

[0008] Preferably, the five-way floating tightening components are arranged in a rectangular array on the milling machine workbench below the base, and the upper part of each five-way floating tightening component is located in the lower rectangular grid hole of the base.
