Description
技术领域technical field
本发明涉及矿用高强度链条技术领域，具体涉及一种链条单环V型缺口对中测量装置及对中控制方法。The invention relates to the technical field of high-strength mine chains, in particular to a chain single-ring V-shaped notch centering measuring device and a centering control method.
背景技术Background technique
矿用高强度链条的链环通常先采用大直径棒料通过编机弯曲成C型开口环，随后用闪光对焊机焊接成闭合的链环。在生产过程中C环开口的对中状态严重影响链环焊接后的力学性能，因此链条生产商通常都需要对链环编制成C型环的开口居中状态进行控制。The link of the high-strength mining chain is usually first bent into a C-shaped open ring by using a large-diameter bar through a knitting machine, and then welded into a closed link with a flash butt welding machine. During the production process, the centering state of the opening of the C-ring seriously affects the mechanical properties of the chain link after welding, so chain manufacturers usually need to control the centering state of the opening of the chain link into a C-shaped ring.
目前控制C型环开口居中状态的方法是直接用普通千分尺103测量。图1为链环居中状态的测量方式示意图。通常是先测量C环左侧单臂101的长度，再测量右侧单臂102的长度，用两侧单臂长度的差值评估C型环开口的居中状态，差值越小则开口居中越好。The current method for controlling the centering state of the opening of the C-shaped ring is to measure directly with a common micrometer 103 . Fig. 1 is a schematic diagram of the measurement method of the centered state of the chain link. Usually, the length of the single arm 101 on the left side of the C-ring is measured first, and then the length of the single arm 102 on the right side is measured, and the centering state of the opening of the C-ring is evaluated by the difference between the lengths of the single arms on both sides. The smaller the difference, the more centered the opening is. it is good.
由于C环开口处形状比较特殊，开口的底部窄，顶部宽，呈V型，用普通千分尺103测量C型链环单臂长度时，卡爪经常难以深入到开口内部，因而难以对其测量起点。另外，普通千分尺103的两个卡爪的长度一般都是相同的，而C型开口链环的测量点不在一条水平线上，具体如图1所示。还有一点就是由于C型链环左侧单臂101和右侧单臂102长度必须分开测量，因此两侧的测量起始点位置是不同的，最终测得的对中情况与实际值往往存在较大差异。Due to the special shape of the opening of the C-ring, the bottom of the opening is narrow, the top is wide, and it is V-shaped. When using an ordinary micrometer 103 to measure the length of a single arm of a C-shaped chain link, it is often difficult for the jaws to go deep into the opening, so it is difficult to measure the starting point. . In addition, the lengths of the two claws of the ordinary micrometer 103 are generally the same, while the measurement points of the C-shaped open link are not on the same horizontal line, as shown in FIG. 1 . Another point is that since the lengths of the left single arm 101 and the right single arm 102 of the C-link must be measured separately, the positions of the measurement starting points on both sides are different, and there is often a discrepancy between the final measured centering situation and the actual value. big difference.
