Inner circle grinder with improved structure

Abstract

The invention discloses an inner circle grinder with an improved structure. According to the inner circle grinder, a fixed base is arranged on the upper surface of a fixed supporting plate of a machine frame in a screwed mode, a grinding driving assembly and a pipe clamping assembly are arranged on the upper end side of the fixed base, the grinding driving assembly comprises a movable middle baseand a movable upper base, a lead screw pair is arranged between the movable middle base and the fixed base, a rack and pinion pair is arranged between the movable upper base and the movable middle base, a grinding driving motor and a spindle mounting base are arranged at the upper end part of the movable upper base, the spindle mounting base is provided with a grinding driving spindle, a power output shaft of the grinding driving motor is connected to the grinding driving spindle in a driving mode through a belt transmission mechanism, a grinding head is arranged at the left end part of the grinding driving spindle, and the pipe clamping assembly comprises a lifting base, a middle base plate, a roller wheel mounting base, a driving supporting roller wheel, a driven supporting roller wheel,a roller wheel driving motor, a movable pressure lever base and a movable pressure roller. The inner circle grinder has the advantages of being novel in structural design, high in adaptability, convenient to use and capable of effectively grinding and machining the inner circumferential surface of a pipe.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to an internal circle grinding machine with improved structure. Background technique [0002] For pipe fittings with high requirements on the inner circumference, the inner circumference of the pipe must be ground by a corresponding grinding device. [0003] Among them, there are various forms of internal grinding devices in the prior art; however, for the existing internal grinding devices, in the actual production process, they generally have unreasonable design, inconvenient use, and poor adaptability. poor defect. Contents of the invention [0004] The object of the present invention is to provide a structurally improved internal grinding machine for the deficiencies of the prior art. The structurally improved internal grinding machine is novel in design, strong in adaptability, easy to use, and can effectively grind the inner circumference of pipe fittings. surface...
