Automatic detection device for cylindrical automobile parts

Abstract

The invention relates to an automatic detection device for cylindrical automobile parts, and effectively solves the problems that the efficiency is low and the detection result is greatly different from the real situation when existing cylindrical parts are subjected to straightness measurement. The technical scheme for solution is as follows: the device can automatically detect the straightness of the inner circle surfaces of the cylindrical parts in a production line under the condition that the production line does not stop, so that the detection efficiency is greatly increased; and moreover, unqualified cylindrical parts can be automatically removed according to the detection result, so that the parts in the production line are all qualified products.

Description

technical field [0001] The invention relates to the technical field of parts detection, in particular to an automatic detection device for cylindrical automobile parts. Background technique [0002] Most of the existing cylindrical parts are first cast into blanks and then finished by grinding. In the above process, it is difficult to ensure the straightness of the inner surface of the cylindrical parts, that is, more or There will be some parts with unqualified straightness. If the factory parts are not inspected, it will lead to aggravated wear of the parts when they are put into use, and there will be large gaps due to the low straightness of the inner circular surface during operation. Noise, vibration, etc., which will shorten the service life of the parts and cause damage to the parts used with it; [0003] Existing detection of straightness of cylindrical parts usually adopts the method of random inspection, that is, a batch of parts are randomly selected from the pa...

Problems solved by technology

[0002] Most of the existing cylindrical parts are first cast into blanks and then finished by grinding. In the above process, it is difficult to ensure the straightness of the inner surface of the cylindrical parts, that is, more or There will be some parts with unqualified straightness. If the factory parts are not inspected, it will lead to aggravated wear of the parts when they are put into use, and there will be large gaps due to the low straightness of the inner circular surface during operation. Noise, vibration, etc., which will shorten the service life of the parts and cause damage to the parts used with it;

[0003] Existing detection of straightness of cylindrical parts usually adopts the method of random inspection, that is, a batch of parts are randomly selected from the parts to be shipped for inspection, but not all parts can be inspected, resulting in unavoidable mix of parts in the factory. Defective products will reduce the pass rate of ex-factory parts. Due to the different standards and judgment levels of different personnel when testing, the test results are also uncertain. Using the above method to measure is time-consuming and laborious, and there are still large errors. lead to inaccurate measurements;
