Description

Process the positioning milling cutter group of propeller lifting eye
Technical field
It the utility model is related to the milling cutter tool that a kind of workpiece used during hole machined.
Background technology
With the development of larger-sized vessel, the weight and diameter of propeller also become big continuous, form large-scale or special type spiral shell Oar, so huge thing are revolved, the safety of lifting eye is lifted to pass always.
The processing of propeller lifting eye, because lifting eye is opened on the propeller hub of propeller, the location of its is being processed When limited by propeller size, therefore it is required that processing lifting eye main shaft it is longer, and main shaft length just to causing hole machined mistake Centering is easily shifted in journey, and centering is bad, and tapping is easily inclined to.
Utility model content
Purpose of utility model:In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of processing propeller lifting eye Positioning milling cutter group, ensure lifting eye process in centering it is consistent.
Technical scheme:It is a kind of process propeller lifting eye positioning milling cutter group, including locating ring, knife bar, tool rest, milling cutter, Axle, the centre of the locating ring is axis hole, offers positioning hole vertically, radially on the locating ring, the knife bar with It is connected between one side of the tool rest by step surface, the milling cutter is located at the circumference of the another side of the tool rest And be connected with the tool rest, the milling cutter being capable of telescopic adjustment, the axle and the axis hole, the another side of the tool rest It is connected, the locating ring is arranged in lifting eye to be processed.
Further, rail groove is offered on the tool rest, the milling cutter is inserted in telescopic adjustment in the rail groove, with institute Tool rest is stated to be connected.
Beneficial effect:Compared with prior art, the utility model has the advantages that:Processing to propeller lifting eye, use Multiple bearing drilling, spitting drill bore hole, positioning tapping, to multiple links in procedure of processing by setting positioning instrument, cut down The longer adverse effect being limited with lifting eye Working position for processing centering of main shaft, ensures that centering is consistent, improves product quality.
Brief description of the drawings
Fig. 1 is the structural representation of positioning milling cutter group.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
A kind of propeller lifting eye processing technology, specifically includes following steps:
Step 100:Propeller is fixed, machine tool position is adjusted, makes machine tool chief axis central alignment lifting eye Working position hole Center.
Step 201:To the hole center of step 100, positioning hole φ 12 × 10 is bored using centre drill;
Step 202:To the positioning hole of step 201, using Twist Drill φ 21 × 30.
Step 300:In the boring surface of step 202, using bottoming drill spot facing φ 51 × 5.
Step 400:In the plane of step 300, using fluted drill reaming φ 45 × 240, reaming is processed at twice, so as to In chip removal.
Step 501:Using the reaming of step 400 as positioning, installed in reaming positioning sleeve A, a bore hole φ 94.2 × 190;
Step 502:Positioning sleeve A is removed, continues bore hole φ 94.2 × 225.
Step 600:To the bore hole of step 502, ream by several times, first time φ 94.6 × 223, second of φ 95 × 220;
Step 700:Using the fraising of step 600 as positioning, positioning sleeve B is installed in fraising, on fraising surface in three times End face milling, first time φ 123 × 40, second of φ 151 × 40, third time φ 160 × 40, then remove positioning sleeve B.
Step 800:Using the end face of step 700 as positioning, positioning sleeve C, heavy boring φ 110 × 170, essence are installed in end face Boring φ 114.2 × 170, then remove positioning sleeve C.
Positioning sleeve A, positioning sleeve B, positioning sleeve C are the middle circle ring columns for offering axis hole.
Step 900:Using the bore hole of step 800 as positioning, the installation positioning milling cutter group in bore hole, in bore surface point three Secondary end face milling, first time φ 192 × 40, second of φ 214 × 40, third time φ 220 × 40.
As shown in Figure 1, it is a kind of process propeller lifting eye positioning milling cutter group, including locating ring 1, knife bar 2, tool rest 3, Milling cutter 4, axle 5.The centre of locating ring 1 is axis hole, and positioning hole A6 vertically, positioning hole radially are offered on locating ring 1 B7, one end of axle 5 are connected with axis hole, are fixed axle 5 and locating ring 1 from positioning hole B7 by screw.
Both are fixed by setting step 8 to connect, and with screw between knife bar 2 and 3 one sides of tool rest.Milling cutter 4 Circumferential edge is stretched out in the another side of tool rest 3 and cutter head, offers rail groove on tool rest, milling cutter, which is inserted in rail groove, to be moved Dynamic telescopic adjustment, is connected with tool rest.The side that the other end of axle 5 installs milling cutter 4 with tool rest 3 is connected.The positioning Ring 1 is arranged in the bore hole of step 800.
Step 1000:End face to step 900 and 8 × 30 ° of chamfering between the bore hole of step 800.
Step 1100:On the end face of step 900, guide sleeve is installed in end face, is connected at the top of screw tap with guide sleeve, it is right The bore hole tapping of step 800.
By above step, propeller lifting hole machined is completed.
