Grinding device for bicycle frame before welding

Abstract

The invention relates to the technical field of bicycles, and discloses a grinding device for a bicycle frame before welding, which includes a bottom plate, a drive motor is fixedly installed in the middle of the top of the bottom plate, and a gear is rotatably connected to the shaft center of the right end of the drive motor 1. The top of the bottom plate is fixedly connected with a reversing mechanism relative to the right side of gear 1, and the top of the reversing mechanism is movably connected with a limit mechanism for clamping the steel pipe of the bicycle frame; the grinding device before the bicycle frame is welded , because the grinding wheel is in contact with the outer walls of both ends of the steel pipe, when the steel pipe rotates, it will drive the grinding wheel to rotate synchronously, and the two ends of the light pipe will be ground to facilitate the subsequent welding work. At the same time, when the grinding wheel rotates, it will drive the coaxial The fixed fan blades rotate to generate suction, and the debris generated during grinding is sucked into the inner cavity of the vacuum housing through the suction port to prevent the debris from polluting the air and affecting human health.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a grinding device for a bicycle frame before welding. Background technique [0002] Bicycle is a common means of transportation in daily life, and is widely used because of its strong practicality and convenience. A bicycle is composed of a vehicle frame, wheels and a transmission mechanism, wherein the vehicle frame is composed of a front fork, a front fork tube, a beam, an oblique beam, a seat tube and a rear fork. And the material of common bicycle rack usually can select steel to make, and steel has better welding performance, is convenient to process, and helps to reduce the overall manufacturing cost of bicycle. Therefore, the front fork tube, cross beam, inclined beam, seat tube, and rear fork are generally welded to each other to form the main body of the vehicle frame. [0003] Since the steel pipes used to assemble the frame are cut, there may be burrs and protrusion...
