Abstract

The invention provides a drilling and boring device with an adjustable central height. The drilling and boring device comprises a tubular bearing block, a bearing block base plate, a boring machine and a boring machine base plate, a sliding bearing is mounted in inner holes at the front end and the rear end of the tubular bearing block, a boring rod shaft is arranged in an inner hole of the sliding bearing, the front end of the boring rod shaft extends out of the front end of the tubular bearing block, the rear end of the boring rod shaft is coupled with the front end of a transmission rod through a first coupling, and the rear end of the transmission rod is coupled with a spindle of the boring machine through a second coupling; the front end of the boring rod shaft is provided with an inner conical hole vertical to the axial direction of the boring rod shaft, and the inner conical hole is used for installation of a boring cutter or a drilling rod; and the bearing block base plate and the boring machine base plate are respectively provided with at least two adjusting bolts which are arranged symmetrically on two sides of the centerlines and are also respectively provided with screw holes matched with the adjusting bolts in a way of penetrating through the upper surfaces and the lower surfaces of the adjusting bolts. The structure is simple and practical, drilling and boring of different parts can be performed through simple changes, the problem of failure in machining resulting from different central heights can be solved, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a high drilling and boring device with adjustable center height. Background technique [0002] Due to the special shape and position of steel members and in order to meet the needs of design, it is often encountered that the height of the round hole to be processed from the base surface to the center line of the round hole is lower than the height from the end face of the processing equipment base to the center line of the equipment spindle. If The small hole diameter below Ф40 generally uses a reamer to ream manually, but the connecting bolt holes of large tonnage ships are designed with a large hole diameter, and special equipment is required to carry out on-site boring processing when processing the inner hole. For example, the machining of the bolt holes connecting the ship stern shaft and the intermediate shaft coupling requires high precision (the error range of conicit...
