Abstract
The utility model discloses a dual-power exploratory boring frock. A screw rod is arranged in a boring rod by a bearing; an exploratory cutter device is arranged on the screw rod; and one end of the exploratory cutter device penetrates through the boring rod. According to a method for processing by adopting the dual-power exploratory boring frock, the boring rod and the screw rod are respectively connected with a driving device, have the same rotating direction and form the radial rotating motion of one or two exploratory cutter devices, i.e. the number of the mounted exploratory cutter devices can be one, two or more and the exploratory cutter devices are used for processing different taper holes. The processing precision of the taper of the taper holes can be ensured by using the tapers of taper sliding chutes on the exploratory cutter devices and the feed of a cutter bar can be realized by using the rotating speed difference between the boring rod and the screw rod, thereby the taper holes meeting the requirement of processing technique can be obtained. The utility model has the characteristics of simple structure, favorable body rigidity, high processing efficiency and the like, and is convenient for installation and use and easy for ensuring the precision.

Taper hole processing is a class problem that often runs in the machining, and processing method commonly used has: the less taper hole of size is processed with taper reamer on drilling machine, lathe, boring machine, milling machine; Geometry comparison rule, appearance profile are relatively than small workpiece and the relatively large taper hole of taper hole size can carry out turning on lathe.Rudder blade belongs to large-sized structural parts, and its geometry is irregular, and appearance profile is big, complex structure, and its taper hole requirement on machining accuracy height is because the particularity of part can't directly adopt said method.At present, domestic shipyard generally uses the processing of large floor boring machine, and technology is backward, processing cost is high, production efficiency is low, labour intensity is big; Perhaps the internal taper hole of two end pieces about the rudder blade is all processed, with a dummy shaft their fastening good backs are welded with other structure of rudder blade then, the coaxiality deviation of the internal taper hole at two ends is very big up and down because of the influence that is subjected to welding stress causes it, its deviation all has nothing in common with each other in all directions, and distance technique requires very far away.Therefore, the difficulty of processing of large-sized rudder blade taper hole is big, and the processing cost height has become mach emphasis of boats and ships and difficult point.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of double dynamical pattern boring technological equipment, can utilize boring machine big at appearance profile, processes the taper hole that meets technological requirement on the baroque workpiece.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of double dynamical pattern boring technological equipment, and leading screw is installed in the boring bar by bearing, and the profiling cutter device is installed on the leading screw, and an end passes boring bar.
Described profiling cutter device is two.
In the described profiling cutter device, moving nut is installed on the leading screw, the knife bar cover is installed on the moving nut by trip bolt, the pattern fixed installation is gone up on the boring bar, pattern is provided with the tapering chute, be movably installed with slide block in the tapering chute, knife bar is fixedlyed connected with slide block, and knife bar one end and knife bar cover are slidingly matched.
Described boring bar is connected with drive unit respectively with leading screw, and the direction of rotation of boring bar and leading screw is identical.
A kind of double dynamical pattern boring technological equipment that the utility model provides, guaranteed the machining accuracy of taper hole by the profiling cutter device, guaranteed the axiality of two taper holes by coaxial installation two cover profiling cutter devices, this frock has simple in structure, the body good rigidly, easy to install, the working (machining) efficiency height, precision is easy to characteristics such as assurance, through repeatedly close beta, guaranteed the higher accuracy of form and position, can effectively solve the technical barrier of rudder blade taper hole processing, satisfy the requirement of rudder blade workmanship, have the excellent popularization using value in shipbuilding industry.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
A kind of double dynamical pattern boring technological equipment, leading screw 8 is installed in the boring bar 3 by bearing, and the bearing at two ends is installed in respectively in left bearing lid 2 and the right bearing lid 9.The profiling cutter device is installed on the leading screw 8, and an end passes boring bar 3.Described boring bar 3 is connected with boring spindle by flange 1, and leading screw 8 is connected with motor 11 by transmission mechanism 10 from the other end, and boring bar 3 is identical with the direction of rotation of leading screw 8.
Described profiling cutter device is two, and coaxial being installed on the leading screw 8 is stressed even for guaranteeing, symmetric arrays on circumference.
In the described profiling cutter device, moving nut 12 is installed on the leading screw 8, knife bar cover 14 is installed on the moving nut 12 by trip bolt 13, pattern 4 fixed installations are gone up on the boring bar 3, pattern 4 is provided with tapering chute 5, be movably installed with slide block 6 in the tapering chute 5, knife bar 7 is fixedlyed connected with slide block 6, and knife bar 7 one ends and knife bar cover 14 are slidingly matched.
A kind ofly adopt above-mentioned double dynamical pattern boring technological equipment method for processing, boring bar 3 is connected with drive unit respectively with leading screw 8, boring bar 3 is identical with the direction of rotation of leading screw 8, form the radially gyration of one or two profiling cutter device, promptly the profiling cutter device of An Zhuaning can be one and also can be two, or even a plurality of, be used for processing respectively different taper holes.Utilize the tapering of tapering chute 5 in the profiling cutter device to guarantee the machining accuracy of taper hole tapering, utilize the speed difference of rotation between boring bar 3 and the leading screw 8 to realize knife bar 7 ground feedings, thereby obtain to meet the taper hole that processing technology requires.
