The invention belongs to the technical field of tool microscopes, and particularly relates to an automobile windscreen wiper transmission gear tool microscope. A glass sheet is arranged above the movable objective table, and a gear clamping mechanism is arranged above the glass sheet; the supporting table is movably arranged on the movable objective table, and a fixed support is arranged on the upper surface of the supporting table; a light-transmitting groove is formed in one corner of the fixed support, and light-transmitting glass is arranged on the bottom end face of the light-transmittinggroove. A driving motor is fixed to the upper end face of the fixed support, and the output end of the driving motor is connected with a rotating supporting column; a rotating strut is sleeved with arotating cylinder, and a supporting cross rod is fixed to the side wall of the rotating cylinder; a clamping disc is arranged at the end of the supporting cross rod and located over the light-transmitting groove. A notch groove is formed in the upper portion of one end of the clamping disc and is aligned with an objective lens of the lens assembly. A rotating gear is rotatably mounted in the clamping disc; the clamping disc is made of a transparent glass material; and the measurement precision and the measurement accuracy of the transmission gear are improved.
Description
technical field [0001] The invention belongs to the technical field of tool microscopes, in particular to a tool microscope for transmission gears of automobile windshield wipers. Background technique [0002] The tool microscope is a mechanical optical instrument based on optical aiming and coordinate measurement. It can be used to measure various lengths and angles. It is especially suitable for measuring various complex tools and parts, such as threads, cam profiles, cutting tools and Hole spacing, etc., a wide range of applications. [0003] The car wiper is mainly composed of DC motor, transmission gear set, connecting rod, swing rod, scraper arm, wiper blade, etc.; Reciprocating motion, the connecting rod then drives the left and right scraping arms to reciprocate through the swing rod, and the wiper blade installed on the scraping arm just scrapes off the rainwater on the glass. [0004] When the existing tool microscope measures the size of this type of transmissio...
