Problems solved by technology

[0002] When the outer circular groove of the existing Bondi tube roll is processed, its tooling is mostly a rotating shaft with a fixed diameter, and the roll is sleeved on the rotating shaft for processing. Since the inner diameters of the rolls produced by various manufacturers are not uniform, they often The inner diameter of the rotating shaft and the roll does not match. The existing method is to fill the gap between the two by plugging. However, the coaxiality of the two depends entirely on the accuracy of the plugging. Once the plugging is not accurate , the coaxiality error between the roll and the rotating shaft becomes larger, and eventually the forming of the roll does not meet the requirements

Abstract

The invention provides a special tool for machining of an outer circle groove of a Bundy pipe roller. The tool comprises a first fitting piece and a second fitting piece. The first fitting piece comprises a fixed shaft, a conical surface shaft, a fastening thread section and a shaft shoulder. The second fitting piece comprises an expansion portion, a conical surface hole, a threaded hole and an expansion groove. The invention further provides a method for using the tool. The method includes the following steps that firstly, the first fitting piece is mounted on a chuck of a lathe; secondly, the conical surface shaft of the first fitting piece is sleeved with the conical surface hole of the second fitting piece; thirdly, the outer circumferential face of the second fitting piece is sleeved with a roller workpiece; fourthly, machining is conducted on one side; fifthly, machining is conducted on the other side; sixthly, the roller workpiece is taken down, and machining is completed. The special tool for machining of the outer circle groove of the Bundy pipe roller has the advantages of being scientific in design, high in precision and low in cost. The machining process for the outer circle groove of the Bundy pipe roller has the advantages that operation is simple, machining precision is high, and the quality of finished products is good.

Description

technical field [0001] The invention relates to a tooling for a Bondi tube roll, in particular to a special tool for processing the outer circular groove of a Bondy tube roll, and also provides a processing technology for the outer circular groove of the Bondy tube roll. Background technique [0002] When the outer circular groove of the existing Bondi tube roll is processed, most of the tooling is a rotating shaft with a fixed diameter, and the roll is sleeved on the rotating shaft for processing. Since the inner diameters of the rolls made by various manufacturers are not uniform, they often The inner diameter of the rotating shaft and the roll does not match. The existing method is to fill the gap between the two by plugging. However, the coaxiality of the two depends entirely on the accuracy of the plugging. Once the plugging is not accurate , the coaxiality error between the roll and the rotating shaft becomes larger, and eventually the forming of the roll does not meet...
