Measuring method and apparatus for size of raceway of one-way sleeve

Abstract

The invention discloses a measuring method and apparatus for the size of a raceway of a one-way sleeve in a one-way clutch of an automobile starting engine and provides a simple, convenient and rapid method for measuring the size of the raceway of the one-way sleeve, which can be used for directly measuring on a production field, stopping unqualified products and increasing the production efficiency. The measuring apparatus provided by the invention comprises a locating core 1, an irregularly-shaped locating ring 3, a joint screw 4, a support 5, a long pin 6, a measurement oscillating bar and a bottom plate 8, wherein the support 5 is arranged on the bottom plate 8, the irregularly-shaped locating ring 3is jointed onto the support 5 by using the joint screw 4, the locating core 1 is inserted to the irregularly-shaped locating ring 3, the measurement oscillating bar 7 is fixed on the support 5 by using the long pin 6, and a meter frame and a dial indicator are well assembled together and fixed on the bottom plate 8. The measuring apparatus can be used for measuring the sizes of different raceways of one-way sleeves. The measuring method and apparatus are applied to a production field, are remarkable in effect and are used for solving the problem that an irregularly-shaped raceway of the one-way sleeve cannot be measured.

Description

technical field [0001] The invention relates to a method for measuring the raceway size of a one-way sleeve and a measuring instrument, in particular to a method for measuring the raceway size of a one-way sleeve in a one-way clutch of an automobile starter and a measuring instrument. Background technique [0002] The one-way sleeve is one of the important parts in the one-way clutch of the automobile starter. Because the inner cavity is a special-shaped raceway, the general measuring tool cannot be measured at all, and the size of the raceway of the one-way sleeve directly affects the performance of the clutch. Therefore, It is inconvenient to measure each batch of products on the three-coordinate, and it is impossible to measure each product well during the production process. In this way, if the product is unqualified due to the wear and tear of the mold during the production process, it cannot be found at all, and a batch of unqualified products will be produced on the p...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a measuring instrument and a measuring method for the size of the one-way sleeve raceway in the one-way clutch of the automobile starter aiming at the problems existing in the above-mentioned prior art, which can overcome the problems through ingenious design and use It solves the problem that the size of the raceway of the one-way sleeve in the one-way clutch of the automobile starter cannot be measured online, and solves the problem that the special-shaped raceway of the one-way sleeve cannot be measured, so that each product can be measured 100% during the production process , not only can measure the specific size, but also can measure the slope of the required segment length by adjusting the standard block of the measuring instrument, eliminating unqualified products from the source
