Full-automatic deep hole meter for lower shaft of steering gear

Abstract

The invention relates to a full-automatic deep hole meter for a lower shaft of a steering gear. The full-automatic deep hole meter comprises a bottom plate, a positioning component fixed on the bottomplate and used for positioning the lower shaft of the steering gear, and a measuring component for automatically measuring bores of the lower shaft of the steering gear. Through cooperation of the positioning component and the measuring component, the full-automatic deep hole meter can automatically measure concentricity of the bores of the lower shaft of the steering gear. The full-automatic deep hole meter is simple to operate, high in measuring precision, high in measuring efficiency, good in universality and worthy of popularization and application.

Description

Technical field: [0001] The invention relates to the field of inner hole measuring devices, in particular to a full-automatic deep hole measuring instrument for the lower shaft of a steering machine. Background technique: [0002] In auto parts, many shaft parts need to measure the concentricity of the inner hole after finishing machining such as turning and milling. In the prior art, common measuring tools such as dial indicators are generally used. Manual measurement has poor measurement accuracy and low measurement efficiency. [0003] In order to improve the measurement accuracy, many manufacturers have improved measuring tools such as dial gauges, such as a large-diameter inner hole measuring tool disclosed by CN106500569A and a deep hole measuring tool disclosed by CN203024675U. These measuring tools It is only improved on the tool body. Although the measurement accuracy can be slightly improved, manual operation is still required. Only one point or one ring in the in...

[0002] In auto parts, many shaft parts need to measure the concentricity of the inner hole after finishing machining such as turning and milling. In the prior art, common measuring tools such as dial indicators are generally used. Manual measurement, poor measurement accuracy and low measurement efficiency

[0003] In order to improve the measurement accuracy, many manufacturers have improved measuring tools such as dial gauges, such as a large-diameter inner hole measuring tool disclosed by CN106500569A and a deep hole measuring tool disclosed by CN203024675U. These measuring tools It is only improved on the tool body. Although the measurement accuracy can be slightly improved, manual operation is still required. Only one point or one ring in the inner hole can be measured at a time, and multiple measurements are required to compare the concentricity. Poor accuracy and low measurement efficiency

Especially for the measurement of the lower shaft of the automobile steering machine, there are multiple sections of inner holes with different diameters in the lower shaft of the automobile steering machine. It is very cumbersome to use this type of measuring tool to measure, which greatly affects the measurement efficiency and poor versatility.
