A high-efficiency reaming machine

Abstract

The invention discloses an efficient hole expanding machine. The efficient hole expanding machine comprises a fixed platform, wherein the side surface of the fixed platform is fixedly connected to one side of a fixed frame; a first motor is fixedly mounted at the right side of the fixed frame; an output shaft of the first motor penetrates and extends into an inner cavity of the fixed frame; the top end of the fixed frame is sleeved with a movable frame in a sliding manner; a second motor is fixedly mounted at one end, far away from a balancing device, of the movable frame; an output shaft of the second motor is fixedly connected to a hole expanding sleeve; a hole expanding rod is fixedly mounted at the bottom end of a fixed sleeve; a hole expanding device located above the fixed platform is fixedly mounted on the hole expanding rod. According to the efficient hole expanding machine, a compression spring drives hole expanding columns at two ends of the hole expanding device, so that the hole expanding columns rotate via centrifugal force; through tension springs, a fixed block and a movable rod can limit the hole expanding size; due to the action of centrifugal force, a hole expanding column is used for continuously moving to two ends and expanding cover holes; the effect of controlling the size is achieved; the hole expanding size can be completed for one time; the error occurrence probability is reduced.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to a high-efficiency hole reaming machine. Background technique [0002] In the existing technology, most of the shafts and the hole position are interference fit, and it is difficult to control the accuracy of the hole diameter. It is effective to measure the hole diameter by manpower or tools. When the hole is expanded, due to the long-term use of the machine, the vibration of the rotating shaft will have a deviation that will affect the size, and the general hole reaming machine is close to the numerical value before manual measurement, which is time-consuming and laborious. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency hole reaming machine to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solut...
