Fixing mechanism of punching machine for machining bicycle wheel spoke holes

Abstract

The invention relates to the technical field of bicycle machining equipment, in particular to a fixing mechanism of a punching machine for machining bicycle wheel spoke holes. The fixing mechanism comprises a machining table top, a first supporting column and a second supporting column, wherein wheel grooves are formed in the first supporting column and the second supporting column, a punching machine part is fixedly arranged on the other side surface of the upper end surface of the machining table top, an intermittent pushing wheel is arranged at the output end of a motor, a gear transmissionshaft is arranged in the first supporting column, a wheel is connected to the gear transmission shaft, and a limiting rotary supporting rod is arranged above a supporting base. According to the fixing mechanism, the intermittent pushing wheel drives the wheel to intermittently move, the punching part punches the bottom of the wheel, the uniformity of spoke holes is improved, the quality of the wheel is improved, punching and adjustment are convenient after convex teeth rotate, the punching precision and the practicability of the device are improved, a roller on the rotary supporting rod is limited, instable transmission caused by shaking of the wheel is prevented, and supporting rollers are convenient for the wheel to rotate, so that the transmission efficiency is improved.

Description

technical field [0001] The invention relates to a fixing mechanism, in particular to a fixing mechanism of a punch press for processing bicycle wheel spoke holes, and belongs to the technical field of bicycle processing equipment. Background technique [0002] Bicycles are loved by the public because of their environmental protection. Today, some cities are equipped with public bicycles to facilitate public travel. At the same time, low-carbon environmental protection is worthy of vigorous promotion. Bicycle wheels are more important in bicycle accessories. Bicycle spokes only Tensile force, not subject to any other force. During normal driving, the tension of the upper spoke increases and the tension of the lower spoke decreases. The difference is used to resist the vertical load acting on the shaft. A qualified wheel should be guaranteed to be at the The spokes below are still under tension, so when weaving the wheel, give the spokes enough tensile stress. If the tension o...

Problems solved by technology

[0003] In the traditional processing of wheel spoke holes, fix the wheel with holes on the wheel in advance, because the holes on the wheel will often cause deformation of the rim, which will affect the service life of the wheel, or other processing methods cannot guarantee the processing accuracy and the quality of the wheels;
