Description

Technical Field

[0001] The utility model belongs to the technical field of transmission shaft detection, and in particular relates to a production detection device for a high-strength agricultural tractor transmission shaft. Background Art

[0002] The tractor drive shaft is the shaft that can transmit power in the universal transmission device. It is a high-speed, low-support rotating body and an important core component in the tractor's transmission system. The outer diameter size of this component is very strict during production and assembly. If you are not careful, defective products may easily flow into the market, resulting in failure to assemble or unqualified assembly. Therefore, the outer diameter size detection of the drive shaft is a very important step in the drive shaft detection process.

[0003] The existing methods for detecting the outer side of the transmission shaft are mostly to measure the outer diameter manually or through simple clamping measuring equipment. Most of them can only measure the outer diameter of one transmission shaft product at a time, with low measurement efficiency. It is not convenient to measure the outer diameter of multiple transmission shafts at the same time, and the work efficiency is low, which cannot meet the use requirements. Utility Model Content

[0015] 3. A set of fixed frames are driven to slide relative to each other through a set of second electric telescopic rods, so that a set of fixed frames slide close to each other to clamp and fix the transmission shaft. The operation is relatively quick and the fixing effect is better. The slide plate is guided by the slide rod to ensure its smooth sliding, which is beneficial to the clamping and fixing operation of the material.
