Embodiment 1

[0034] A large-diameter inner hole vertical lathe polishing tool, such as figure 1 As shown, it is used for polishing the large-diameter inner hole of the workpiece 6, including a main body block 1, a connecting plate 2, a honing strip 3 and an elastic element 4, wherein:

[0035] The main body block 1 is used to be connected to the tool rest 5 of the vertical lathe, and has a working end 101 for pointing to the inner hole side wall 61 of the workpiece 1 fixed on the rotary table of the vertical lathe. The working end 101 of the main body block 1 is provided with Mounting groove 102; the connecting plate 2 is embedded in the mounting groove 102, and has an extension 22 protruding from the opening of the mounting groove 102. The connecting plate 2 can slide relative to the mounting groove 102 on the straight line where the working end 101 points to. The honing strip 3 is arranged at the end of the extension 22 of the connecting plate 2;

[0036] The present invention utilizes ...

Embodiment 2

[0041] An integrated processing method for increasing the roughness of a large-diameter inner hole in this embodiment, using the tooling of Embodiment 1, includes the following steps:

[0042] S1: The workpiece continues to maintain the clamping state of the previous process (usually the previous process refers to the inner hole of the workpiece) on the rotary table of the vertical lathe, and the tooling is installed on the tool holder of the vertical lathe;

[0043] S2: Rotate the workpiece, move the tool holder of the vertical lathe along the radial direction of the workpiece, drive the tooling to move to the side wall of the inner hole of the workpiece, so that the honing strip is close to the side wall of the inner hole of the workpiece under the action of the elastic element;

[0044] S3: The tool holder of the lathe moves in the axial direction of the workpiece, and the side wall of the inner hole is processed by the honing strip to improve the roughness of the inner hole...

Abstract

The invention relates to a vertical-lathe polishing tool and an integrated machining method for improving roughness for a large-diameter inner hole. The tool comprises a main body block, a connectingplate, a honing abrasive strip and an elastic element, wherein the main body block is used for being connected to a vertical-lathe tool rest and is provided with a working end used for pointing to theside wall of an inner hole of a workpiece fixed to a vertical-lathe rotary workbench, and a mounting groove is formed in the working end of the main body block; the connecting plate is embedded in the mounting groove and provided with an extending part protruding out of an opening of the mounting groove, and the connecting plate can slide on a straight line where the pointing direction of the working end is located relative to the mounting groove; the honing abrasive strip is arranged at the tail end of the extending part of the connecting plate; and the elastic element is arranged in the mounting groove, acts on the connecting plate and applies elastic force pointing to the direction outside the mounting groove to the connecting plate. Compared with the prior art, the tool and the methodare simple and efficient, low in cost and capable of adapting to large-diameter inner hole machining with the high roughness requirement, the workpiece can be clamped on a vertical lathe at a time, machining is completed, and the form and location tolerance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of large-diameter inner hole processing, in particular to a large-diameter inner hole vertical lathe polishing tool and an integrated processing method for improving roughness. Background technique [0002] At present, for cylinder bores with a size larger than Φ1000mm and a roughness drawing requirement of less than 1.6, the manufacturer does not have machine tools to process them. Although the outsourcing unit has a special machine tool, the processing cost is high and the processing cycle cannot be guaranteed. production progress. Therefore, manufacturers need a viable and inexpensive solution. Contents of the invention [0003] The object of the present invention is to provide a large-diameter inner hole vertical lathe polishing tool and an integrated processing method for improving roughness. It is simple, efficient, low in cost, and can adapt to the processing of large diameter inner holes with hig...
