Boring machine for inner wall of drying drum

Abstract

The invention discloses a boring machine for the inner wall of a drying drum. The boring machine comprises a base, and a head and a tailstock which are installed on the base. A chuck driven by a main power device is installed on the head, a centre is installed on the tailstock, the centre and the chuck are arranged coaxially, a driving supporting seat and a driven supporting seat are installed between the head and the tailstock on the base in a sliding mode, the driving supporting seat is driven by an auxiliary power device to slide, fixing plates are arranged on the driving supporting seat and the driven supporting seat, a fastening device for fixing the drying drum is installed on each fixing plate, a boring bar is installed between the chuck and the centre, one end of the boring bar is clamped on the chuck, the other end of the boring bar is tightened by the centre, and a boring tool assembly is installed on the boring bar. According to the boring machine, through improvement of the original common centre lathe, not only corresponding boring bars can be selected according to the inner diameter of the drying drum and requirements for the machining accuracy, but also power output of the main power device can be reduced, energy resources are saved, and the service life of the machine is prolonged.

Description

technical field [0001] The invention relates to equipment for boring the inner cylinder wall of a drying cylinder, in particular to a boring machine for the inner cylinder wall of a drying cylinder after refitting a common lathe. Background technique [0002] At present, it is difficult to bore holes on the inner wall of large drying cylinders, and special equipment is needed. However, these special equipments are expensive and cannot be purchased by general manufacturers. A lot of cost. At present, the boring on the ordinary lathe is realized in this way, the drying cylinder is fixed on the lathe through special fixing equipment (such as the outer center frame), the drying cylinder is driven to rotate by the chuck of the lathe, and the active support seat of the lathe is fixed There is a tool holder rod, on which a boring tool is installed, and the active support seat slides under the drive of the auxiliary power device to make the boring tool bore holes on the inner cylin...

[0002] At present, it is difficult to bore holes on the inner wall of large drying cylinders, and special equipment is needed. However, these special equipments are expensive and cannot be purchased by general manufacturers. a lot of cost

At present, the boring on the ordinary lathe is realized in this way, the drying cylinder is fixed on the lathe through special fixing equipment (such as the outer center frame), the drying cylinder is driven to rotate by the chuck of the lathe, and the active support seat of the lathe is fixed There is a tool holder rod, on which a boring tool is installed, and the active support seat slides under the drive of the auxiliary power device to make the boring tool bore holes on the inner cylinder wall. The tool holder rod of this structure is in the shape of a cantilever, which not only Intensified, and the trend of withdrawal becomes larger, which reduces the accuracy of the boring, and the chuck drives the drying cylinder to rotate, requiring the active device to provide sufficient power output, resulting in increased energy consumption of the lathe
