Line edge detection tool for detecting symmetry degree of bayonet of bearing cover and detection method of line edge detection tool

Abstract

The invention discloses a line edge detection tool for detecting the symmetry degree of a bayonet of a bearing cover, and the detection tool comprises a fixed plate, a detection mechanism and a push structure, the detection mechanism comprises a cross rod, a supporting rod, a first threaded sleeve, a supporting plate, a detection seat, a dial indicator fixing rod, a dial indicator and a second motor, and the top surface of the fixed plate is provided with a semicircular reference block. And an arc sheet is arranged on the cambered surface of the semicircular reference block. The device is small and exquisite in structure and small in occupied area; the manufacturing cost is low, and the detection work can be carried out orderly while the cost expenditure of an enterprise is reduced; the structure of the detection seat effectively prevents an operator from accidentally touching and impacting the detection head, has the function of protecting the detection tool, ensures the detection precision, and prolongs the service life of the detection tool part. The device is accurate in positioning and detection, can adjust the positioning reference according to different types of bearing caps, is convenient to position, and improves the detection efficiency.

Description

【Technical field】 [0001] The invention belongs to the technical field of detection of engine parts, and in particular relates to a line edge inspection tool for detecting the symmetry of a bayonet of a bearing cap and a detection method thereof. 【Background technique】 [0002] The bayonet of the seventh gear bearing cover of the cylinder block of some engine models needs to install the oil pump assembly (including oil pump bracket, oil pump and other components), so the symmetry accuracy of the bayonet is extremely high. If it is out of tolerance, it will affect the assembly performance of the engine oil pump assembly. [0003] At present, the method of detecting the amount of the bearing cap bayonet is to use a three-coordinate detection machine for detection. Because the equipment is large in size, expensive, and easy to be damaged by collision, it is usually arranged on the production line at a frequency of 1 set per shift. , so in the work of testing the mouth symmetry ...
