Abstract
A grinding mechanism of a numerical control curve grinding machine belongs to the part of a grinding machine. The prior numerical control curve grinding machine has the defects that rough grinding and fine grinding cannot be finished on a same grinding machine in one circulation process or a long axis connected by a grinding wheel is overlong to be easy to generate radial runout. The grinding mechanism of a numerical control curve grinding machine comprises a machine body, a workpiece spindle head, a drag plate and two grinding wheel spindle heads, wherein the workpiece spindle head can move on the machine body through connecting with an X-axis guide pair, a Z-axis guide pair and the drag plate; a motor provides power through a guide screw pair to realize the movement of the workpiece spindle head in each direction; and the two grinding wheel spindle heads are fixedly mounted on the machine body, with the spindles parallel to the spindle on the workpiece spindle head, one spindle provided with a coarse plain emery wheel and the other spindle provided with a fine plain emery wheel. The utility model can finish rough grinding and fine grinding on the same grinding machine in one circulation process, enhances the rigidity of the spindles, reduces the runout of the long axis connected by the grinding wheel, and improves the grinding efficiency.
Description
Technical field
The utility model belongs to the grinding machine parts, and is especially relevant with a kind of numerical control contour grinder grinding mechanism.
Background technology
The blank of non-circular curve or the heat treated blank of process, their distortion is all bigger, its grinding allowance is also bigger, for improving grinding efficiency, the general corase grind that all will carry out big stock removal earlier, and then finish grind and guarantee precision, the corase grind of big stock removal uses coarse plain emery wheel, the general fine grinding wheel that uses of correct grinding.At present, the grinding mechanism of numerical control contour grinder has dual mode, and a kind of is the single grinding head structure, is exactly the emery wheel form of installing on the main shaft, and such grinding mechanism can only be roughly ground or finish grind, and does not satisfy the requirement that should high stock removal guarantees precision again; Another kind of mode is that thick, thin two emery wheels are installed on the main shaft, can realize corase grind and correct grinding, but such grinding mechanism main shaft is owing to will install two emery wheels, just need the lengthening main shaft, the high speed of main shaft just has bigger circular runout when rotating, influence machining accuracy, also cause grinding wheel spindle and Workpiece clamping head to produce simultaneously easily and interfere.
The utility model content
The utility model purpose is exactly will solve existing numerical control contour grinder to exist and can't be on same grinding machine finish that corase grind and correct grinding or emery wheel spreading axle are long to be easy to generate the defective that circular runout influences machining accuracy in circulation, and a kind of high precision numerical control profile grinder grinding mechanism that can roughly grind and can finish grind is provided.For this reason, the utility model is by the following technical solutions:
The numerical control contour grinder grinding mechanism, comprise lathe bed, workpiece spindle box and planker, lathe bed is provided with X-axis guideway and lead screw pair, the leading screw of lead screw pair is fixedlyed connected with motor, be fixedly mounted on the slide block of X-axis guideway and and fixedly connected with the nut of lead screw pair, the planker end face is provided with Z axis rail pair and lead screw pair, the Z axis rail is secondary vertical with the X-axis guideway, lead screw pair is fixedlyed connected with motor, workpiece spindle box is fixedly installed on the slide block of Z axis rail pair and with the nut of lead screw pair fixedlys connected, the guide rail axially parallel of main shaft on the workpiece spindle box and Z axis rail pair, the slip of workpiece spindle box and planker provides power by motor by lead screw pair, it is characterized in that: also be installed with two grinding wheel spindle box-shapeds on the described lathe bed and become two grinding stations, main shaft on the grinding wheel spindle case is all parallel with the main shaft on the described workpiece spindle box, coarse plain emery wheel is installed on the main shaft of one of them grinding wheel spindle case is used to roughly grind processing, fine grinding wheel is installed on the main shaft of another grinding wheel spindle case is used to finish grind processing.
As to technique scheme further replenish and perfect, the utility model also comprises following additional technical feature:
Described grinding wheel spindle case is installed on lathe bed by installing rack.
The utility model adopts two grinding wheel spindle casees to form two grinding wheel head structures, when being used for grinding, clamping workpiece on the main shaft of workpiece spindle box rotates at a slow speed, the main shaft of grinding wheel spindle case drives emery wheel and rotates at a high speed, workpiece is roughly ground processing by workpiece spindle box at the corase grind station earlier under the moving interpolation of X, Z axle drives, be processed into the non-circular curve shape; After corase grind was finished, workpiece moved to the correct grinding station by workpiece spindle box and finish grindes processing.
The utility model can reach following beneficial effect: adopt two grinding wheel spindle casees to form two grinding wheel head structures, realized that on same equipment once clamping is not only roughly ground but also finish grind, improved working (machining) efficiency, guaranteed the high accuracy of processing, avoided simultaneously influencing machining accuracy owing to main shaft produces circular runout.
