The technical scheme of the utility model is realized like this: the utility model provides an excircle measuring device with adjustable mandrel finish machining is used, includes last measuring rack, with last measuring rack through threaded connection's last connecting rod, lower measuring rack, with lower measuring rack through threaded connection's lower connecting rod, install the fixed gauge head on measuring rack down, through the percentage table of bolt fastening on last measuring rack, go up and adopt transition fit between connecting rod and the lower connecting rod, realize going up reciprocating of connecting rod in the connecting rod down to through bolt fastening locking.
The lower connecting rod is a hollow lower connecting rod, the upper connecting rod is inserted into the lower connecting rod and moves up and down in the hollow lower connecting rod, and meanwhile, the lower connecting rod is locked and fixed through a bolt after the position is determined.
The upper connecting rod is provided with a front-back communication groove from top to bottom, the bolt penetrates through the lower connecting rod and is inserted into the groove, the upper connecting rod is guaranteed to move up and down in the lower connecting rod along the bolt, and meanwhile the bolt locks and fixes the upper connecting rod and the lower connecting rod together after the position is determined.
The utility model discloses positive effect that technical scheme produced as follows: the measuring and monitoring of the outer circle size of the core rod can be realized without stopping the equipment, and the quality of the product is ensured to meet the process requirements. The utility model provides an online measurement and control of plug excircle size in the course of working, avoid causing the plug excircle size out of tolerance, excircle out of roundness out of tolerance or local production to connect phenomenons such as sword platform because of stopping the bed repeatedly and measuring, and can advance the adjustment according to plug external diameter size, but the diameter tolerance and the out of roundness of effective control product satisfy the technological requirement through the adjustable measurement table frame of preparation.
