Description
Technical field
The present invention relates to technical fields of mechanical processing, and in particular to a kind of shipping rudder blade taper hole boring row.
Background technology
Internal taper hole (including rudder stock taper hole and rudder pintle taper hole) in shipping rudder blade, is typically added in factory with numerically-controlled machine tool
Work, such as the numerical control borer with square ram may be used, in the feed simultaneously of X, Y both direction, form taper hole.Using in factory
The rudder stock taper hole and rudder pintle taper hole of processing will also carry out splicing assembling after completion of processing, to ensure marine shafting in outfield
It is coaxial to require.
But the shipping rudder blade that some special mountings require, it needs to process while outfield carries out two internal taper holes, to protect
Its required precision is demonstrate,proved, while shortening the adjustment time of splicing assembling.But since outfield lacks processing conditions, internal taper hole adds
Work difficulty is larger.For this purpose, there is an urgent need to develop go out it is a kind of can outfield implement shipping rudder blade inner cone hole machined special tooling.
Invention content
To solve the above-mentioned problems, the present invention proposes a kind of shipping rudder blade taper hole boring row, it is intended to realize shipping rudder blade inner cone
The processing in hole, specific technical solution are as follows：
A kind of shipping rudder blade taper hole boring row, including be respectively used to be arranged shipping rudder blade taper hole front and back end front axle bolster,
Bearing bracket stand afterwards, and be supported on the front axle bolster, the boring bar on rear bearing bracket stand, be provided in the outer circle of the boring bar relative to
The inclined guide level of axis of boring bar, excavating on the guide level has the guide-track groove vertical with the guide level, described
Be connected with the follow rest that can be moved axially along the guide level and guide-track groove on guide-track groove, the follow rest by
The lead screw that is arranged in the guide-track groove drives, and one end of lead screw bearing bracket stand rearward is rotatably connected to the boring bar
Rear end, and one end end of lead screw bearing bracket stand rearward is connected with spider gear, and monodentate gear is provided with by the spider gear
Block, the monodentate block fixed setting, and the monodentate on the monodentate block is connected with the spider gear.
In the present invention, the follow rest includes the mobile sliding block being slidably matched with the guide-track groove, is connected to the shifting
Tool-post structure on movable slider.
Wherein, be provided with knife rest nut with the junction of the lead screw on the mobile sliding block, the knife rest nut with
The wire rod thread is connected.
When boring row is installed, front axle bolster, rear bearing bracket stand are fixed on to shipping rudder blade both ends to be processed.When processing, boring row
It is driven by power plant and generates rotary motion, lead screw equally and then rotates, since lead screw is rotated around boring row center line, equally
Spider gear on lead screw is also rotated around boring row, and spider gear is as a planetary gear, when certain tooth of spider gear encounters list
When tooth link stopper, spider gear drives one low-angle of lead screw rotation while revolution, equally makes the mobile sliding block in guide-track groove
Micro distance is moved along guide-track groove so that follow rest block also moves micro distance, with the continuous rotation of boring row, knife
Frame body is constantly moved also along guide rail so that the boring cutter on tool-post structure is in constantly bore hole, the axis due to boring bar with lead
Rail plane is at an angle of inclination, therefore the boring cutter on tool-post structure is axially also walking out the track tilted with axis, to reach
The purpose of boring taper hole.
In the present invention, the front axle bolster, rear bearing bracket stand respectively include bearing body, are arranged in the bearing body endoporus
Sliding bearing, the two supports of the boring bar are in the sliding bearing.
As a further improvement on the present invention, it is provided with for aligning between the bearing body endoporus and the sliding bearing
Support ring, the sliding bearing be mounted on the support ring in, there are tune between the support ring and the bearing body endoporus
Gap in the heart, the circumferential position of bearing body endoporus described in the bearing body upper edge is provided with a number of adjusting screw, described
Withstand the outer circle of the support ring in the front end of adjusting screw.
The setting of above-mentioned front axle bolster, rear bearing bracket stand upper centring support ring and adjusting screw, facilitates boring row when mounted
Position adjustment.
In order to realize the processing for carrying out shipping rudder blade end face while boring taper hole, close to the rear axle on the boring bar
The front position of bolster is provided with plane knife rest.
The setting of plane knife rest in above-mentioned boring row, on the one hand realizes the processing of shipping rudder blade end face, on the other hand due to
Internal taper hole and end face are the processing completed under clamped one time, and internal taper hole can be made to have higher verticality with end face.
In the present invention, the sliding bearing both ends in the front axle bolster are connected separately with thrust bearing, the thrust bearing
By being fixed on the boring bar and realizing axially position by flat Hough locating ring with the end face of the thrust bearing.
In the present invention, the sliding bearing both ends in the rear bearing bracket stand are connected separately with thrust bearing, the thrust bearing
Axially position is realized by the plane knife rest and the Hough locating ring being arranged in the boring bar rear end.
In the present invention, the guide level is equal to the half of shipping rudder blade angle of countersink with the angle of the boring bar axis.
In the present invention, the boring bar drives rotation by the power head being connected with the front end of the boring bar.
When outfield carries out the processing of shipping rudder blade taper hole, to ensure two tapered holes (rudder stock taper hole and rudder pintle taper hole)
Concentricity can disposably bore four basic circles first with common long boring row on the big small end of two taper holes, remove long boring
Row, then taper hole boring row of the invention is loaded onto on single taper hole, the both ends basic circle previously bored is subjected to school circle, then boring cone
Hole, end flat and seam allowance etc..It waits for removing boring row after a cone hole machine and moves on to another cone hole machine, by same sample prescription
Method bore hole.The concentricity of two taper holes has thus been completely secured.
The beneficial effects of the invention are as follows：
First, a kind of shipping rudder blade taper hole boring row of the invention is tilted by being arranged on boring bar with the boring bar axis
Guide level is vertical and guide-track groove perpendicular to the guide level so that being mounted on follow rest on guide-track groove can be
It is moved axially along the direction parallel with the guide level, therefore the boring cutter on tool-post structure also walks out in axial direction and mutually inclines with axis
Oblique track, to achieve the purpose that boring taper hole.
Second, a kind of shipping rudder blade taper hole boring row of the invention, front axle bolster, rear bearing bracket stand upper centring support ring and adjusting
The setting of screw facilitates the position adjustment of boring row when mounted.
Third, a kind of shipping rudder blade taper hole boring row of the invention, the setting of plane knife rest, on the one hand realizes ship in boring row
The processing of oceangoing ship rudder blade end face can make interior on the other hand since internal taper hole and end face are the processing completed under clamped one time
Taper hole has higher verticality with end face.
4th, a kind of shipping rudder blade taper hole boring row of the invention can make two tapered holes (rudder stock taper hole and rudder pintle cone
Hole) there is higher concentricity, to improve the quality of shipping rudder blade.
