Abrasive belt grinding machine

Abstract

The invention discloses an abrasive belt grinding machine, relates to the field of workpiece polishing and aims to adjust the pressure between an abrasive belt and a to-be-ground workpiece during thepolishing process so as to enable grinding to be uniform, save the abrasive belt and improve the polishing efficiency. According to the main technical scheme, the abrasive belt grinding machine comprises a grinding machine body as well as a first clamping part and a second clamping part fixed on the grinding machine body and arranged oppositely, and further comprises a polishing part and a grinding head support mechanism; the first clamping part and the second clamping part are fixing the two ends of the to-be-ground workpiece separately; the first clamping part is connected with a rotary driving part; the rotary driving part is used for driving the first clamping part to drive the to-be-ground workpiece to rotate; the polishing part comprises the abrasive belt and a grinding head; the abrasive belt is wound on the outer side of the grinding head and is used for being driven by rotation of the grinding head to move relative to the to-be-ground workpiece; one end of the grinding head support mechanism is fixed on the grinding machine body; the other end of the grinding head support mechanism is used for supporting the grinding head; and the grinding head support mechanism is used for changing the contact pressure between the abrasive belt and the to-be-ground workpiece. The abrasive belt grinding machine is mainly used for polishing the workpiece.

Description

technical field [0001] The invention relates to the field of workpiece grinding, in particular to an abrasive belt grinder. Background technique [0002] With the continuous development and progress of science and technology, grinding machines have been widely used in industrial production. Grinding machines are integrated equipment that use abrasive tools to grind the surface of workpieces. Common grinding machines use high-speed rotating grinding wheels or abrasive belts to grind workpieces. grinding process. [0003] Grinding with an abrasive belt grinder is a way to achieve oil pipe grinding operations. However, when grinding, the grinding head is lowered to the position by its own weight and pressed on the workpiece at one time. The new abrasive belt that has just been replaced has the best grinding effect. When the abrasive belt wears out, the grinding quality will drop significantly after a few leads, resulting in uneven grinding; in order to ensure the quality, the ...

[0003] Grinding with an abrasive belt grinder is a way to achieve oil pipe grinding operations. However, when grinding, the grinding head is lowered to the position by its own weight and pressed on the workpiece at one time. The new abrasive belt just replaced has the best grinding effect. When the abrasive belt wears out, the grinding quality will drop significantly after a few leads, resulting in uneven grinding; in order to ensure the quality, the abrasive belt must be replaced in time, which wastes both the abrasive belt and the grinding time, resulting in a decrease in production speed
