AI Technical Summary
The existing ram-type vertical lathes have a column located directly behind the base, which limits the maximum diameter of the machine tool, increases the machine tool's weight and floor space, and raises the cost of use.
The system employs an offset column layout, with the column guide rails staggered front and rear, combined with lifting and horizontal/vertical feed mechanisms, to expand the processing diameter.
Without increasing the weight and floor space of the machine tool, the machining diameter can be increased to 1.8m, reducing operating and manufacturing costs.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical equipment, specifically relating to a ram-type vertical lathe with an offset column. Background Technology
[0002] In common ram-type vertical lathes, the column is typically positioned directly behind the base. This configuration significantly impacts the maximum workpiece diameter that the machine can process, often requiring the column to be moved further back to achieve a larger processable diameter. However, this also increases the overall length of the machine base. This not only increases the overall weight of the machine but also its footprint, thus raising both operating and manufacturing costs. Utility Model Content
[0003] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a ram-type vertical lathe with an offset column.
[0004] Technical solution: A ram-type vertical lathe with offset column, including a bed base, a machining area is provided at the front of the bed base, and a column is offsetly connected to the bed base;
[0005] A lifting mechanism is fixedly installed on the column, and the column is provided with two staggered first column guide rails and second column guide rails; a crossbeam is installed on the first column guide rail and the second column guide rail, and the crossbeam moves up and down on the first column guide rail and the second column guide rail surface through the lifting mechanism.
[0006] A slide block is provided on the crossbeam, and the slide block can move left and right on the crossbeam via a transverse feed mechanism; a ram is fixedly installed on the slide block, and the ram moves up and down at the center of the slide block via a longitudinal feed mechanism, ultimately completing the cutting process of the machine tool.
[0007] As an optimization: the processing area is a circular area.
[0008] As an optimization: the column is located at the right rear of the bed base.
[0009] As an optimization: the lifting mechanism is fixedly installed in the middle of the column.
[0010] As an optimization: the slide block is fixedly installed at the center of the slide seat.
[0011] Beneficial effects: This utility model, by adopting an overall layout with an offset column and front-to-back column guide rails, further increases the machining diameter. Without increasing the weight of the original machine tool castings or the machine tool's footprint, the maximum diameter of the workpiece that the machine tool can process is increased compared to machine tools of the same level using a traditional layout, raising the machining diameter from 1.6m to 1.8m, thus reducing operating and manufacturing costs.

[0014] Example
[0015] like Figure 1-2 As shown, a ram-type vertical lathe structure with an offset column includes a bed base 1. A machining area 2, which is circular, is provided at the front of the bed base 1. A column 3 is offsetly connected to the bed base 1, and the column 3 is located at the right rear of the bed base 1.
[0016] A lifting mechanism 4 is fixedly installed in the middle of the column 3. The column 3 is provided with two staggered first column guide rails 51 and second column guide rails 52. A crossbeam 6 is installed on the first column guide rails 51 and second column guide rails 52. The crossbeam 6 moves up and down on the surfaces of the first column guide rails 51 and second column guide rails 52 through the lifting mechanism 4.
[0017] A slide block 7 is provided on the crossbeam 6, and the slide block 7 can move left and right on the crossbeam 6 via a transverse feed mechanism 8. A ram 9 is provided at the center of the slide block 7, and the ram 9 can move up and down at the center of the slide block 7 via a longitudinal feed mechanism 10, ultimately completing the cutting process of the machine tool.
[0018] This invention, by adopting an overall layout with an offset column and front-to-back column guide rails, further increases the machining diameter. Without increasing the weight of the original machine tool castings or the machine tool's footprint, the maximum diameter of the workpiece that the machine tool can process is increased compared to machine tools of the same class using a traditional layout, raising the machining diameter from 1.6m to 1.8m, thus reducing operating and manufacturing costs.
