Description
Technical field
This utility model belongs to machining field, relates to a kind of elastic tool rest, is specifically related to a kind of main bearing journal and crank-pin polish elasticity tool rest.
Background technology
Low speed heavy-duty diesel oil machine crankshaft is the main rotating mechanism of boat diesel engine, it is responsible for and pumping of piston is changed into the circular motion of self, therefore the processing conditions of bent axle is the strictest, trunnion and the roughness of excircle of crank-pin and form and position tolerance suffer from the highest requirement, but because the particularity of crankshaft structure, grinding machine can not be used to process, special crankshaft toothed wheel can only be used to carry out turning.
When with crankshaft toothed wheel turning bent axle, due to the particularity of crankshaft structure, it is impossible to use the method for feed back and forth to come machining spindle neck and crank-pin, and the zigzag cutter suitable with axle journal width and wide cutter can only be used to process；The biggest additionally, due to bent axle weight, the measure that lathe two is fixedly clamped can not be taked, but bent axle can only be placed on multiple centre frame, utilize the method for bent axle deadweight and the reverse clamping of cutter to process, in the course of processing, workpiece is easy to produce vibration, thus affects the quality of polish.
Summary of the invention
This utility model purpose is to provide one both to have met crankshaft journal processing particularity to overcome the deficiencies in the prior art, can reduce again the vibration in the course of processing thus ensure main bearing journal and the crank-pin polish elasticity tool rest of polish quality.
nullFor reaching above-mentioned purpose，The technical solution adopted in the utility model is: a kind of main bearing journal and crank-pin polish elasticity tool rest，It includes the installation portion being connected with main carriage、For installing the fixed platform of process tool and connecting described installation portion and the elastic of described fixed platform，Described elastic includes the first contiguous block that end is connected with described installation portion、The second contiguous block paralleled with described first contiguous block and be arranged side by side、The 3rd contiguous block that is parallel with described second contiguous block and that be connected with described fixed platform、Connect described first contiguous block and the first arc block of the second contiguous block and connect the second arc block of described second contiguous block and the 3rd contiguous block，It is provided with adjustment pad between described second arc block and described installation portion，It is additionally provided with on described installation portion and runs through described adjustment pad and insert the multiple screws in described second arc block.
Optimally, described fixed platform offers multiple cutter fixing hole, the fixed platform between described 3rd contiguous block and described cutter fixing hole is additionally provided with multiple adjustment hole, described adjustment hole is provided with the adjustment block corresponding with process tool.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that this utility model main bearing journal and crank-pin polish elasticity tool rest, by using the first contiguous block, the second contiguous block, the 3rd contiguous block, the first arc block and the entirety elastic in serpentine of the second arc block composition, and adjustment pad is set between the second arc block and installation portion, so can improve efficiency and the quality of processing according to the elasticity of the whole elastic tool rest of extent of vibration regulation and rigidity in turning process.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model preferred embodiment is described in detail:
Main bearing journal as depicted in figs. 1 and 2 and crank-pin polish elasticity tool rest, mainly include the parts such as installation portion 1, elastic 2 and fixed platform 3.
Wherein, installation portion 1 is connected with main carriage, and in the present embodiment, it has and the draw-in groove 11 of main carriage phase clamping, thus is arranged on main carriage by whole elastic tool rest.Fixed platform 3 is provided with multiple cutter fixing holes 31 that shape is in a row, is used for installing process tool.Elastic 2 connects installation portion 1 and fixed platform 3, it includes integrated first contiguous block the 21, second contiguous block the 22, the 3rd contiguous block the 23, first arc block 24 and the second arc block 25, first contiguous block the 21, second contiguous block the 22, the 3rd contiguous block 23 is all vertically arranged so that they are parallel to each other, form interval and side-by-side alignment；The upper end of the first contiguous block 21 is connected with installation portion 1, and lower end is then connected by the lower end of the first arc block 24 with the second contiguous block 22；The upper end of the second contiguous block 22 is connected with the upper end of the 3rd contiguous block 23 by the second arc block 25, making elastic 2 entirety in serpentine, such second arc block 25 can be to be defined according to the direction observed in Fig. 1 about the narration in direction near installation portion 1().Adjustment pad 4 so can be set between the second arc block 25 and installation portion 1, be additionally provided with on installation portion 1 simultaneously and run through the multiple screws 5 adjusted in pad 4 and insertion the second arc block 25.Adding man-hour, if vibration is relatively big in turning process, then screw 5 is being unscrewed, utilize elastic 2 structure to increase whole tool rest elastic, eliminate vibration；If vibrating less, then can tighten screw 5 so that the rigidity of whole tool rest increases, and can improve efficiency and the quality of processing.
In the present embodiment, multiple adjustment holes 32 that shape is in a row it are additionally provided with in fixed platform 3 between 3rd contiguous block 23 and cutter fixing hole 31, by screw, the adjustment block 6 corresponding with process tool is installed on adjustment hole 32, utilize and each adjustment hole 32 inner bolt is carried out regulation in various degree, thus reach to change the purpose of the process tool blade depth of parallelism.
