Problems solved by technology

However, the existing cutting tools start cutting from the outer wall of the cylindrical workpiece, and it is difficult to ensure that the cylindrical workpiece with a thin wall thickness will not be deformed by force during cutting, resulting in plastic deformation of the cylindrical workpiece after cutting, resulting in a change in size.

[0017] Combine figure 1 with figure 2 The cylindrical inner wall cutter includes a three-pronged support frame 1. Three columnar columns 2 of equal length are vertically arranged on the three edges of the bottom surface of the support frame 1, and a cylindrical elastic column 8 is vertically arranged on the inner wall of the column 2 , The ends of the three elastic columns 8 are vertically provided with arc-shaped plate-shaped outer wall clips 7, and a bearing 6 is vertically embedded in the center of the support frame 1. The bearing 6 and the three outer wall clips 7 are all coaxial. The ring is fixed and penetrated with an L-shaped round tubular threaded elbow 3. The threaded elbow 3 is located on the bottom side of the support frame 1 and bends vertically. The threaded elbow 3 is provided with a threaded rod 5 that is threaded with it, and the end of the threaded rod 5 is provided There is a cutting head with a pointed tip 4.

Abstract

The invention discloses a barrel inner-wall cutter and relates to the field of mechanical equipment. In use of the barrel inner-wall cutter, a threaded rod and a cutter bit can be inserted inside a barrel workpiece, three vertical posts keep surrounding the outer wall of the workpiece, elastic posts are stressed to be bent, and three outer-wall clamps closely fit to fix the barrel workpiece; the cutter bit is inserted to the inner wall of the barrel workpiece by screwing the threaded rod in a threaded bend, the thread bend is then rotated in a bearing to drive the threaded rod and the cutter bit to rotate a circle, and thus, the inner wall of the barrel workpiece can be cut off. With the barrel inner-wall cutter, flatness of the cutting plane of the barrel workpiece can be guaranteed, andthe barrel workpiece with thin wall is not easy to deform when cut.

Description

Technical field [0001] The invention relates to the field of mechanical equipment, in particular to a cylinder inner wall cutter. Background technique [0002] When cutting many thin-walled cylindrical workpieces, it is often necessary to keep the cutting section very flat and to keep the cylindrical workpieces from deforming after being cut. However, the existing cutting tools start cutting from the outer wall of the cylindrical workpiece, and it is difficult to ensure that the cylindrical workpiece with a thin wall is not deformed by force during cutting, resulting in plastic deformation and size change of the cylindrical workpiece after cutting. Summary of the invention [0003] The main technical problem solved by the present invention is to provide a cylindrical inner wall cutter, which can ensure that the cutting surface of the cylindrical workpiece is flat, and can ensure that the cylindrical workpiece with a thin wall is not easily deformed by force during cutting. [0004]...
