Technical field
The present invention relates to a kind of grinding machine, particularly relate to a kind of strength forming grinder with machine-shaping ability.
Background technology
Various saw blades, saw blade is the cutter that must dispose in the cutting technique, have a large capacity and a wide range, traditional sawtooth processes with milling machine, and the sawtooth fineness of Milling Process is poor, and crown is not sharp, (cutting edge circular arc 〉=0.1mm) jagged, so draw bad phenomenon such as tooth, run easily, have a strong impact on the service life of saw blade.
Various tooth bars are widely used a kind of machine components in the mechanical straight-line motion mechanism, usually adopt and mill, insert, or the gear hobbing processes, and high-precision tooth bar, after above-mentioned processes moulding, also need to carry out fine finishining with grinding machine, (need with the supporting processing in groups of the lathe of two kinds of models, time-consuming, cutter consumption is big, the processing cost height.) become the bottleneck that hinders mechanical industry development, so urgent hope has a kind of new advanced manufacturing technology to replace the original old technology that falls behind.
Grinding machine is a kind of common machining equipment, general-purpose grinder is to utilize emery wheel that grinding is carried out on the surface of workpiece, to improve the fineness and the precision of surface of the work, general-purpose grinder is very little to the grinding allowance of workpiece, productivity ratio is very low, can not directly carry out grinding-shaping processing to workpiece, because traditional grinding, the emery wheel loss is very fast, must often repair emery wheel by dresser, make emery wheel recapture the form accuracy and the sharpness on surface. finishing back is because the reducing of emery wheel size, and the compensation rate of its emery wheel is restive so influence the machining accuracy of grinding, then influences bigger for form grinding.
Chinese invention patent ZL02152114.X discloses a kind of grinder wheel trimmer, this is a kind of dresser of numerical control, can repair accurately the curved surface of emery wheel, but this dresser is mounted on the Grinder bench, that is to say, have only workpiece taken off from workbench after, change crushing reason device and could repair emery wheel, will frequently load and unload like this, lower efficiency.
China utility model patent ZL93206055.2 discloses another kind of grinder wheel trimming device, it is that a freeing wheel is installed on the column of grinding machine, freeing wheel be positioned at emery wheel directly over, by a haulage gear freeing wheel can be moved up and down, thereby freeing wheel is contacted with emery wheel or break away from, when freeing wheel contacts with emery wheel, can repair emery wheel.But this apparatus structure complexity, and the supporting structure rigidity of freeing wheel is relatively poor.
For strength forming grinder, although the retentivity of emery wheel is fine, but several batches of workpiece of continuous grinding after the crushing once also need trimming wheel, so these two kinds of dressers obviously are inapplicable.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of strength forming grinder, and its wheel dresser structure is simple, and is easy to use, and Size Accuracy in Grinding Process keeps consistency.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of strength forming grinder, comprise lathe bed, workbench, bistrique and trimmer, and described trimmer is installed on the lathe bed, and trimmer is positioned at the back of workbench, the back lower place of emery wheel.
In the present invention, trimmer is installed on the lathe bed, and its position is fixed, and neither needs to dismantle back and forth, does not need that also haulage gear is set and moves it, therefore simple in structure, use convenient.When emery wheel when the worker advances forward, can carry out grinding to the workpiece on the workbench; Draw back when emery wheel and to be freeing wheel when top, promptly finish crushing. after finishing a working cycles, emery wheel can be parked in the middle of workbench and the trimmer, and emery wheel does not contact with workpiece, trimmer at this moment.
As the preferred version of technique scheme, comprise a freeing wheel in the described trimmer, the final grinding face of workpiece flushes on the last wheel rim of described freeing wheel and the workbench.Like this through the emery wheel of trimmer finishing forward the worker advance when workpiece carried out grinding, can once reach desired grinding depth.Not moving because of dresser during each the finishing, is that bistrique moves down, so the trim amount of emery wheel can not have influence on grinding accuracy, so dresser of grinding machine of the present invention, except the abrasive wheel forming finishing, also has the cutting-in size Control, three effects of compensation automatically of crushing amount.
Above-mentioned workbench, emery wheel and trimmer are respectively by a driven by servomotor, and above-mentioned three servomotors are connected with a four-shaft numerically controlled system by an interface circuit.Utilize digital control system and servomotor to carry out accurately to grinding machine, control fast, crushing can be carried out simultaneously at the Workpiece transfer work step.After workpiece is transferred the clamping that puts in place by pay-off, lathe will automatically carry out by the program of setting, high-pressure coolant constantly rushes at the surface of emery wheel during grinding, the dirt removal that stops up wheel face is clean, the pressure lubricating cooling fluid is broken through the air-flow of wheel face in the big flow, most heat in the grinding area is taken away, lowered the temperature.
Numerical control automatic tooth profile strength forming grinder of the present invention. can process the profile of tooth and the various tooth bar of various saw blades expeditiously, gear, the processing of the profile of machine components such as zanjon. use grinding machine of the present invention to process the flute profile of various saw blades, working (machining) efficiency height not only, cost is low, and crown sharp (≤0.005mm), no burr, cutting edge highly polished, not easy-to-draw tooth, run has improved the service life and the cutting-rate of saw blade.
This advanced person's grinding machine is than traditional grinding machine, and working (machining) efficiency has improved thousands of times, and (strength forming grinder not only can substitute the lathe of original two kinds of models, also can replace the productivity ratio of 3 ~ 5 groups of group of planes.) greatly improved grinding efficiency because of strength forming grinding new technology, its stock removal rate even mill also fast than whirlwind, can reach with mill and mill for car, generation, be specially adapted to the processing of big cutting-in (a time cutting-in can reach 25 millimeters) shaping workpiece, the loss of grinding tool is very little, and production cost has only 1/4 of Milling Process, the machining accuracy height, the dimensional tolerance high conformity is processed highly polishedly, and crudy is guaranteed.Also can process various hard-cutting materials.
Different with general-purpose grinder, grinding machine of the present invention can be directly carry out a cutting-in (thick, fine finishining) processing and forming to workpiece, for example workpiece is carried out the processing of groove, curved surface, can the various tooth bars of form grinding, workpiece such as sawtooth.Although the stock removal of grinding machine of the present invention is big, but the loss of emery wheel is very little, the abrasive wheel forming retentivity is good, but for the uniformity of accurate to dimension in keeping producing in enormous quantities with reduce unproductive time, improve the automaticity of lathe, it is particularly important that the method for crushing also seems concerning strength forming grinder.
