Device and method for measuring side precision of gear of automobile transmission

Abstract

The invention discloses a device and method for measuring the side precision of a gear of an automobile transmission. The device comprises a laser plane generator, a laser detection target and a movement mechanism controlled by an embedded system. A first connecting rod and a second connecting rod of the movement mechanism control upward movement and downward movement of the laser plane generator and the upward movement and the downward movement or horizontal movement of the laser detection target through a first servo mechanism and a second servo mechanism. The laser plane generator is in tight contact with or separated from a detected plane through a first electronic control magnetic base, and when the laser plane generator is in contact with the detected plane, a laser plane is generated. The laser detection target is in tight contact with or separated from the detected plane through a second electronic control magnetic base, when the laser detection target is in contact with the detected plane, the height value of the laser plane is measured, measured data are directly transmitted to the embedded system, and a measurement result is displayed through the screen of the embedded system finally. According to the device and method for measuring the side precision of the gear of the automobile transmission, the laser plane is used as a measurement datum, and the measurement precision is high; automation of the measurement process is achieved through the movement mechanism controlled by the embedded system, and therefore the measurement speed is improved.

Description

technical field [0001] The invention relates to a gear side precision measuring device and method, in particular to a measuring device and method for the gear side precision of an automobile gearbox. Background technique [0002] As a key component of the car, the quality of the gear directly affects the comfort and reliability of the car. Improving the factory quality of automobile gears is not only the guarantee of automobile quality, but also the guarantee of personal safety. At present, the traditional detection methods are still used in the production process of automobile gears in our country, and there is a lack of effective online detection devices. For example, the side accuracy of the spiral bevel gear is detected by manual feeler gauge, relying on the degree of insertion of the feeler gauge to detect whether the side accuracy of the gear meets the quality requirements of the product. Although this method is simple to operate, the accuracy is low and there are hum...

For example, the side accuracy of the spiral bevel gear is detected by manual feeler gauge, relying on the insertion degree of the feeler gauge to detect whether the side accuracy of the gear meets the quality requirements of the product. Although this method is simple to operate, the accuracy is low and there are human factors. , different people at different time periods, the strength of the feeler gauge is different, the measurement results are different, and there is a lot of randomness in the measurement results
