Abstract
Provided is a large-scale special machine for machining rudder blade inner taper holes. Main motion of the special machine is rotating motion of boring rods, a continuously variable transmission with a first-level reducing gear serves as a main motion driving device, and cutting motion is achieved through a planet gear. The special feeding motion is linear feeding cutting motion of boring heads installed on the boring rods. The boring heads of the boring rods are driven to conduct feeding motion sequentially. Gears of output shafts of transmission devices are meshed with gear rings sleeving the boring rods in an idle mode, and the corresponding transmission devices are driven by the gear rings according to the machining requirement conversion positions to drive the boring heads to machine the taper holes, stop openings, end faces and the like of rudder blades respectively according to programs.
Description
Technical field
The present invention is a kind of large-sized rudder blade internal taper hole special machine tool, is exactly a kind of special machine tool that is applied to rudder blade internal taper hole in shipping industry specifically.
Background technology
Along with the develop rapidly of shipbuilding industry, shipyard must possess the ability of manufacturing large vessel, and large-sized rudder blade taper hole is mach Focal point and difficult point.Due to the particularity of part, large-sized rudder blade taper hole can not be processed on conventional equipment, must adopt large-sized numerical control boring machine or special machine tool processing.In shipyard at home, use large-sized numerical control floor type boring machine machining large rudder blade taper hole.Obviously, there are a lot of shortcomings, as backward in process technology, machining accuracy is low, production efficiency is low, labour intensity is large, processing cost is high.Compare with large-sized numerical control boring machine, the special machine tool of automation has the advantage of oneself, as use flexibly, cost is low, efficiency is high.
Summary of the invention
The object of this invention is to provide that a kind of machining accuracy is high, apart from each other and will keep the large-sized rudder blade internal taper hole special machine tool compared with high-axiality.
The object of the present invention is achieved like this:
It mainly comprises composition stepless speed changer, dedicated boring rod, taper roll bearing, duplicate gear etc.
Its operation principle is such:
The actual size on surface is larger everywhere to consider processing taper hole etc., and the rotary speed of boring bar should not be too high, and the rotating speed of motor output is higher, so select stepless speed changer.MB series planet friction-type mechanical stepless transmission is mainly made up of the aggressive device compressing, slip gear, speed regulation control mechanism.
The effect of boring bar has been roughing, semifinishing and the fine finishining of seam, lower surface and the taper hole inner surface of upper and lower taper hole.。
Taper roll bearing can separate, and the assembly being made up of together with roller, retainer inner ring and outer ring can be installed respectively.The contact wire of roller and raceway contact point correction can reduce stress and concentrate.Taper roll bearing can bear large radial load and axial load.Because taper roll bearing can only transmit unidirectional axial load, therefore, just need another symmetrical taper roll bearing of installing with it for transmitting rightabout axial load.。
Duplicate gear is made up of a bevel gear and a straight spur gear, for processing the switching between taper hole and processing end face, switches by adopting fine pitch trapezoidal thread to connect between setscrew nut and duplicate gear and realizing.When duplicate gear is when left-handed, the anterior bevel gear of duplicate gear engages with bevel gear 8, realizes the processing of seam and end face.
Its operation acts process is such:
Rudder blade has upper and lower two taper holes, and requirement can be processed tapering 1:10-1:15.Boring bar is arranged on bearing support, and bearing support is connected with eight collar nuts that are welded on rudder blade temporarily respectively.The main motion of special plane is rotatablely moving of boring bar, and main motion, by making main motion drive unit with the buncher of primary speed-down gear, realizes cutting movement by planetary gear.The feed motion of special plane is mounted in the straight-line feed cutting movement of the boring head on boring bar.Feed motion, successively drives each boring head of above-mentioned two boring bars to do feed motion.Gear ring on boring bar engages the gear of transmission device output shaft with empty set, then is shifted one's position and drive respectively the each boring head follow procedure of corresponding actuator drives to process respectively the taper hole of rudder blade, seam, end face etc. by the requirement of processing by this gear ring.
The invention has the beneficial effects as follows:
Alleviate labor strength, increase work efficiency.
Realize the automation of higher degree.
Use is flexible, cost is low.
Can be for the processing of various types of rudder blade taper holes, and better assembly machine technology can be provided.

Detailed description of the invention
In conjunction with Fig. 1 and Fig. 2, large-sized rudder blade cone hole machine position has: taper hole, seam and end face, and must design multifunctional special boring bar.On boring bar, must there be cone boring head, straight boring head and end key head.On each boring head (knife rest), be provided with feed micro-adjusting mechanism and relieving mechanism.Feed micro-adjusting mechanism is upper slitter accurately.When relieving mechanism can make knife rest motion reach home, automatically allow cutter head depart from surface of the work, both protected point of a knife, avoid again knife rest in the time of rapid return, to scratch surface of the work.
Boring bar is arranged on bearing support, and bearing support is connected with eight collar nuts that are welded on rudder blade temporarily respectively.The main motion of special plane is rotatablely moving of boring bar, and main motion, by making main motion drive unit with the buncher of primary speed-down gear, realizes cutting movement by planetary gear.The feed motion of special plane is mounted in the straight-line feed cutting movement of the boring head on boring bar.Feed motion, successively drives each boring head of above-mentioned two boring bars to do feed motion.Gear ring on boring bar engages the gear of transmission device output shaft with empty set, then is shifted one's position and drive respectively the each boring head follow procedure of corresponding actuator drives to process respectively the taper hole of rudder blade, seam, end face etc. by the requirement of processing by this gear ring.
