Vehicle cab hydraulic lock detection apparatus

The utility model relates to a vehicle cab hydraulic lock detection apparatus and belongs to the mechanical manufacture field. An air cylinder is mounted on a fixed supporting plate; the front end of the air cylinder rod of the air cylinder is connected with a pull pressure sensor through a connecting component; the pull pressure sensor is installed on a lock rod type moving tool; the contraction and stretch of the air cylinder rod of the air cylinder along a vertical direction drives the lock rod type moving tool to move up and down along a guide polished shaft; the lock rod type moving tool is corresponding to a rotary tool; the rotary tool is installed on a replaceable tool through a tested hydraulic lock and is connected with a hydraulic lock small oil cylinder through a quick clamp; and the replaceable tool is connected with a cam indexer through a connecting component. The vehicle cab hydraulic lock detection apparatus has the advantages of simple operation, stable performance, high control precision and accurate acquisition. The vehicle cab hydraulic lock detection apparatus has all functions of a common apparatus, and can realize double-working position detection. A variety of detection data can be displayed through a touch screen; once a start button is pressed, a whole testing process can be continuously completed; and therefore, the vehicle cab hydraulic lock detection apparatus further has the advantages of convenient use and high practicability.
