Abstract
Description
Technical Field
[0001] This utility model relates to a crankshaft gear plate testing instrument, belonging to the field of crankshaft testing technology. Background Technology
[0002] For the inspection of crankshaft gear disc blanks entering the production line and finished products leaving the production line, existing inspection systems typically use fixed-position measuring probes to measure the crankshaft gear discs. During the crankshaft assembly process, due to the significant weight of the crankshaft itself, operators need to expend considerable physical strength and energy to complete the work. Over time, operator fatigue is inevitable, leading to a decline in their attention, judgment, and operational accuracy. This fatigue often results in operational errors, most commonly causing contact and collision between the crankshaft gear disc and the measuring probe. Such collisions not only damage the measuring probe, reducing its measurement accuracy and lifespan, but may also damage the crankshaft gear disc itself, leading to product scrap or requiring additional repair work.
[0003] Damage to measuring probes and crankshaft gears not only increases repair and replacement costs for businesses but also severely impacts production efficiency and product quality. The need for remeasurement and repair can force production line shutdowns, leading to production delays and postponements of customer deliveries.
[0004] Therefore, it is necessary to develop a new type of testing device to achieve accurate, efficient and reliable testing of crankshaft gear disc blanks going online and finished products going offline. Utility Model Content
