Embodiment 1

[0034] Embodiment one is basically as attached figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 Shown:

[0035] A machining process for a motorcycle main shaft, comprising the following steps:

[0036] Step 1. Material selection: choose carbon structural steel or alloy structural steel as the blank. And the shape of the rough blank is a round rod. Among them, the carbon structural steel is carbon structural steel 15 steel, 20 steel or 45 steel. Alloy structural steel is alloy structural steel 20Cr, 40Cr, 50Mn or 60Mn.

[0037] Step 2, preliminary processing: heating and forging the rough blank in step 1;

[0038] Step 3, reprocessing: normalize the rough blank after heating and forging in step 2; then carry out carburizing and quenching after finishing turning, the depth of the carburized layer is 0.6-1.0mm, and the hardness after quenching and tempering is 59- 64HRC. Then finish machining to form the main shaft parts.

[0039] Ste...

Embodiment 2

[0057] Such as Figure 7 The difference between the present embodiment and the first embodiment is that the sliding connection between the slide plate 122 and the switch door 12 is different: the switch door 12 is provided with a bar-shaped chute 124 on the surface of the side inside the vehicle body 1, and the bar-shaped chute 124 is provided with a groove 1241 on both sides of the inner wall; one side of the slide plate 122 is slidably connected in the strip chute 124, and both sides of the slide plate 122 are also provided with positioning protrusions inserted into the groove 1241 respectively; Part 123 (stage compression spring) is fixed between the bottom wall of bar-shaped chute 124 and the bottom surface of slide plate 122 .

Abstract

The invention relates to the technical field of transportation, and particularly relates to a processing technique for a motorcycle main shaft. The processing technique comprises the steps of (1) selecting materials: selecting carbon structural steel or alloy structural steel as blanks; (2) preliminarily processing: heating and forging the blanks in the step (1); (3) reprocessing: normalizing theblanks which are heated and forged in the step (2), then carburizing and quenching after finish turning, and performing finish machining so as to form a main shaft part; (4) grinding: grinding the main shaft part in the step (3), during grinding, grinding the excircle first, then aligning according to the ground excircle, and then grinding an inner hole; and (5) transferring: transferring the mainshaft part which is ground in the step (4) by adopting a cart, wherein the main shaft part falls on a cover plate during transferring, the cover plate rotates downwards around a hinged position, andthe main shaft part rolls downwards along the cover plate and falls into the cart. According to the processing technique of the scheme, the problems of easiness in damage to the part when the part falls into the cart from a high place and easiness in attachment of dust during transportation in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a processing technology for a motorcycle main shaft. Background technique [0002] At present, the processing of shaft blank parts such as motorcycle spindles is mainly processed by die forging. During the processing of parts, the problem of transfer and transportation is often involved. Trolley is a kind of commonly used carrying tool, and trolley has the branch of one-wheel, two-wheel, three-wheel and four-wheel. The body material of traditional trolleys is generally wood, while the body material of modern trolleys is generally iron sheet; trolleys for different purposes have different body structures. [0003] Existing trolleys for conveying in workshops generally include a car body, a push handle positioned on the car body and a roller positioned at the bottom surface of the car body; in addition, in order to prevent the push handle from wearing down the worker's palm...
