Apparatus for machining circular guide rails of revolving doors

Abstract

The invention provides a device for machining a circular-ring-shaped guide rail of a revolving door. A circular-ring-shaped supporting frame is provided with a plurality of clamping frames; a supporting stand column is arranged at the center of the circular-ring-shaped supporting frame; a fixed friction column is arranged above a part to be machined and on the periphery of the supporting stand column; the top end and the side face of the supporting stand column are integrally provided with a motor bracket which can rotate for 360 degrees around the supporting stand column; a swinging-arm rotary motor is arranged at the lower end of the motor bracket; an output shaft of the swinging-arm rotary motor is located inside the motor bracket and is fixedly connected with a gear; the gear is respectively engaged with two friction wheels which can move along the fixed friction column; the motor bracket is fixedly provided with a horizontal swinging-arm guide rail which can rotate for 360 degrees around the supporting stand column along with the motor bracket; and the swinging-arm guide rail is provided with a driving mechanism which is provided with a milling cutter and can drive the milling cutter to move up and down as well as left and right. The device for machining the circular-ring-shaped guide rail of the revolving door is simple in structure and fine in machining, guarantees the stability of the movement of an idler wheel, and overcomes noises.

Description

technical field [0001] The invention relates to a cyclone milling device. In particular, it relates to a device for processing circular guide rails of revolving doors. Background technique [0002] Because the automatic revolving door has the characteristics of beauty, convenience, environmental protection and energy saving, it is more and more used in high-end hotels and high-end office buildings. [0003] However, because the ring-shaped guide rail on the revolving door is spliced ​​by several arc-shaped guide rails, and the deformation in the arc-drawing process, the spliced ​​guide rail surfaces are not in the same plane, causing the rollers to be in the same plane. Movement on it is jerky, not smooth, and creates noise. [0004] With the improvement of people's quality of life, higher requirements are put forward for the stability and noise of the revolving door. Contents of the invention [0005] The technical problem to be solved by the present invention is to pr...
