Problems solved by technology

If the position of the pin hole does not meet the requirements, it will directly lead to the unbalanced load of the planetary gear transmission, which will greatly reduce the life of the entire gear transmission system
At present, the finishing of pin holes mainly adopts high-precision horizontal or vertical boring and milling machines, and cooperates with three-coordinate detectors to ensure its position requirements. It restricts the mass production efficiency; or adopts a special measuring fixture, which also has the above-mentioned problems

Embodiment Construction

[0038] Objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments. These embodiments are only typical examples of applying the technical solutions of the present invention, and all technical solutions formed by adopting equivalent replacements or equivalent transformations fall within the protection scope of the present invention.

[0039] As shown in the figure, the invention discloses an online detection method for the position degree of the pin hole of the planet carrier. There are pin hole 1, pin hole 2, pin hole 3 and reference hole 4 on the planet carrier, and the three pin holes are evenly distributed, and the nominal value of the distribution circle diameter is d 5 . The center of circle of described datum hole 4 is set as coordinate origin, and the circle center coordinates of pin hole 1, pin hole 2, pin hole 3 are respectively (x 1 ,y 1 ), (x 2 ,y 2 ), (x 3 ,y 3...

Abstract

The invention discloses an on-line detection method of position degrees of pin holes of a planet carrier. The on-line detection method comprises steps of by use of a common inside micrometer and a double-bulb micrometer, measuring the short distance between every pin holes and a standard hole and the short distance among the pin holes online; and the obtaining precise data of position degrees of the pin holes of the planet carrier via calculation. In this way, on-line detection of the position degrees of the pin holes of the planet carrier is achieved; time for disassembly, inspection and shut-down waiting is avoided; processing while detecting and timely repairing and correcting when there is a problem are achieved; and effectively safeguard measures are provided for lean manufacturing.

Description

technical field [0001] The invention relates to a method for detecting the machining accuracy of a pin hole of a planetary frame, in particular to an online detection method for the position degree of a pin hole of a planet frame. Background technique [0002] The planetary carrier is an important part in the planetary gear transmission, and in the manufacturing process of the planetary carrier, the position of the pin hole is the key point and also the difficulty. If the position of the pin hole does not meet the requirements, it will directly lead to the unbalanced load of the planetary gear transmission, which will greatly reduce the life of the entire gear transmission system. At present, the finishing of pin holes mainly adopts high-precision horizontal or vertical boring and milling machines, and cooperates with three-coordinate detectors to ensure its position requirements. It restricts the mass production efficiency; or adopts a special measuring fixture, which also...
