Problems solved by technology

The use of tapered boring bar processing has a series of disadvantages such as high cost, large volume and weight of tooling, low processing accuracy, non-adjustable processing taper, and low reuse rate of boring bar; while using boring machine processing, not only the processing cost is high, but also produces Additional hoisting and transportation costs, the most important thing is that the processing size is limited (cannot process larger or extra-large workpieces)

Embodiment Construction

[0026] Taper-adjustable tapered hole boring machine, including drive system, straight boring bar 8, two boring bar support devices, inclined guide rail installation clamp 33, axial feed device, tapered hole processing cutter head 29 and end surface processing tool assembly .

[0027] The straight boring bar 8 is provided with a semicircular groove 9 along the axis, and the two ends of the boring bar are provided with glands 10 on the end face of the boring bar. The drive system includes a variable frequency motor 1, a variable frequency motor control box 3 and a worm gear transmission. The worm gear transmission includes a worm 4, a worm wheel 5, and the worm wheel 5 and the worm 4 mesh. The shaft gear on the frequency conversion motor output shaft is connected with the shaft gear on the worm screw 4 shaft through the belt 2. The shafts at both ends of the worm screw 4 are respectively supported by bearing housings 6 with bearings, and the two bearing housings 6 are fixed on...

Abstract

The conic hole boring machine with adjustable taper includes motor, hole boring cutter, straight boring rod and worm. The motor is connected to the shaft of worm through belt; the worm is meshed with one worm gear mounted on the straight boring rod; the straight boring rod is supported with two supporting units; the conic hole boring cutter is connected to one inclined guide rail with dovetail groove and lead screw groove; and the lead screw inside the lead screw groove is connected to the conic hole boring cutter. The inclined guide rail is fixed onto one clip on the straight boring rod and has the inclination angle adjustable. Each of the boring rod supporting units includes conic sleeve, casing and support board. The present invention has compact structure, small size, light weight, easy assembling and disassembling, simple and accurate conicity regulation, high boring precision and other advantages.

Description

(1) Technical field [0001] The invention relates to a boring processing machine, in particular to a tool for boring a taper hole of a ship rudder blade and a machine for boring a tool for a taper hole of a large-scale equipment. (2) Background technology [0002] Taper hole processing of ship rudder blades and taper hole processing of large-scale equipment is a difficult problem in the manufacture of large-scale equipment such as ships and heavy machinery. Since the taper hole of the ship rudder blade and the taper hole of large-scale equipment belong to the shaft hole of the transmission shaft or the inner hole of each bearing hub of the transmission device, the workpiece is bulky and heavy after assembly, and it is impossible to achieve high-efficiency and high-precision machine tool processing. However, the above-mentioned The tapered hole requires extremely high dimensional accuracy, taper, roundness, coaxiality and roughness in the manufacturing process. [0003] In th...
