Abstract
The invention discloses a machining method of a material head of a large mill. The method includes the technical steps of (1) preparation before machining, (2) clamping, (3) leveling and aligning and (4) machining. The machining method of the material head of the large mill has the advantages that precision machining quality of the material head of the large mill is improved; one-time clamping of all relevant size faces is completed; the planeness and the coaxiality of the relevant faces are guaranteed, and machining efficiency is improved because the piece turning frequency is reduced.
Description
Technical field
The present invention relates to a kind of production and processing way of stub bar, be specifically related to a kind of machining process of large-sized grinder stub bar, belong to large ore machining technique field.
Background technology
After cast casting completes, need to the machined surface of foundry goods be machined to ore machine apparatus assembling by machining operation needs size and precision, so that engineering is installed while using, coordinates.What adopt in the industry at present mostly is vertical lathe processing mating surface, adopts a minute order processing mode, has needed the processing of one end then to turn over part and just can complete the processing of other one end, and this need to repeat be installed for twice and turn over part.The shortcoming of this way is: for large-scale stub bar, extended activity duration and process-cycle; Turn over part danger high, turn over piece number more, cause security incident probability larger; Repeatedly be installed and turn over part and can cause foundry goods damage, destroying crudy; Be difficult to ultra-large type stub bar by the processing of quality.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of machining process of large-sized grinder stub bar, solved in large-scale stub bar processing prior art the process-cycle long, danger is high, and quality such as cannot guarantee at the problem.
The technical method of the machining process of a kind of large-sized grinder stub bar of the present invention is:
Step 1: prepare before processing
First extension parallels is arranged on workbench; Again claw and equal-height padding iron are arranged on extension parallels; Then by workpiece flat winch to workbench directly over, and then vertical landing is implemented on equal-height padding iron the casting technique boss of workpiece completely;
Described extension parallels is arranged on workbench by 45 °, bolt interval.
Step 2: be installed
Utilization is arranged on the claw extending on parallels and inwardly blocks die casting fabrication technique boss, workpiece is fixed on and extends on parallels; Pressing plate is pressed in the inner hole surface of casting technique boss by bolt.
Step 3: levelling capturing
Levelling: dial gauge is inhaled on the knife rest below machine ram, and rotary table drives workpiece rotation; Transfer ram and make dial gauge pointer press to the flange face of workpiece, inspection pointer is beated, and will on the equal-height padding iron of the downward-sloping relevant position of flange face, pad upper cushion block, until make the flange face of workpiece beat after worktable rotary, reaches in Process Planning definite value.
Centering: dial gauge is inhaled on the knife rest below machine ram, and rotary table drives workpiece rotation; Transfer ram and make dial gauge pointer press to the inner headed face of workpiece, inspection pointer is beated, and adjusts claw, until make the inner headed face of workpiece beat after worktable rotary, reaches in Process Planning definite value.
Described Process Planning definite value is for requiring to set according to the required difference of the different stub bars of casting;
Step 4: processing
Car end face of flange, as machining benchmark; Car child periphery, as other disc machining benchmarks; The large flange of the car back side, making flange face and back side theoretical planes degree is zero; The inside and outside disc of car, making the theoretical axiality of inside and outside disc and child's periphery is zero; The little flange of the car back side, the theoretical planes degree that makes the little flange back side and other planes is zero.
The invention has the beneficial effects as follows: the machining process of a kind of large-sized grinder stub bar of the present invention
Improved large-sized grinder stub bar fine finishining quality; Completed the processing that is once installed of all relevant property size faces; Flatness, the axiality of correlation surface have been guaranteed; Reduced and turned over piece number and therefore improved working (machining) efficiency.
Accompanying drawing explanation
Fig. 1: the manufacturing drawing of large-sized grinder stub bar
Wherein: machine ram 1, workpiece 2, workbench 3, casting technique boss 4, claw 5, extension parallels 6, equal-height padding iron 7, pressing plate.
The specific embodiment
Below in conjunction with accompanying drawing, 1 couple of the present invention is further analyzed, the present invention specifically in four steps:
Step 1: prepare before processing
First 45 °, extension parallels 6 use bolt interval is arranged on workbench 3, according to the diameter of workpiece 2, specifically adjusts and extend parallels 6 from the outward extending distance of workbench 3; Again claw 5 and equal-height padding iron 7 are arranged on extension parallels 6; Then by workpiece 2 flat winch to workbench 3 directly over, and then vertical landing is implemented on equal-height padding iron 7 the casting technique boss 4 of workpiece 2 completely.
Step 2: be installed
Utilization is arranged on the claw 5 extending on parallels 6 and inwardly blocks die casting fabrication technique boss 4, workpiece 2 is fixed on and extends on parallels 6; Pressing plate 8 is pressed in the inner hole surface of casting technique boss 4 by bolt.
Step 3: levelling capturing
Levelling: dial gauge is inhaled on the knife rest below machine ram 1, and rotary table 3 drives workpiece 2 rotations; Transfer ram 1 and make dial gauge pointer press to the flange face of workpiece 2, inspection pointer is beated, and will on the equal-height padding iron of the downward-sloping relevant position of flange face 7, pad upper cushion block, until workbench 3 rotates a circle, the flange face of interior workpiece 2 is beated and reached in Process Planning definite value;
Centering: dial gauge is inhaled on the knife rest below machine ram 1, and rotary table 3 drives workpiece 2 rotations; Transfer ram 1 and make dial gauge pointer press to the inner headed face of workpiece 2, inspection pointer is beated, and adjusts claw 5, until workbench 3 rotates a circle, the inner headed face of interior workpiece 2 is beated and reached in Process Planning definite value;
Wherein: Process Planning definite value is for requiring to set according to the required difference of the different stub bars of casting.
Step 4: processing
According to following benchmark, process, obtain satisfactory stub bar: car end face of flange, as machining benchmark; Car child periphery, as other disc machining benchmarks; The large flange of the car back side, making flange face and back side theoretical planes degree is zero; The inside and outside disc of car, making the theoretical axiality of inside and outside disc and child's periphery is zero; The little flange of the car back side, the theoretical planes degree that makes the little flange back side and other planes is zero.
