The invention relates to a numerical control shovel grinder workpiece head frame, belonging to the technical field of machine processing equipment. The numerical control shovel grinder workpiece head frame is characterized in that a motor stator is fixed in the head frame body; a motor rotor is fixed on a mainshaft; the lower end of the mainshaft is provided with a bearing; a bearing external ring is arranged in a side cover hole; the upper end of the mainshaft is provided with the bearing; the bearing external ring is arranged in the upper cover hole; an oil seal liner, a dial plate and an upper cover are respectively arranged on the mainshaft; the end of the mainshaft is provided with the oil seal; a tip is arranged at the center of the mainshaft; a round angle encoder is sheathed at the end of the mainshaft. The numerical control shovel grinder workpiece head frame has simple, compact and reasonable structure and eliminates the backlash and accumulated error of the original worm and worm wheel pair transmission; the indexing precision ranges from -2'' to +2''; the axial jump quantity is less than 0.005 Mum; the error of tooth profile, pitch and heading edge helix of the high-precision hob is controlled within few microns; the head frame which transmits the rotation of the workpiece has stable rotation process and the indexing precision is ranging from -3 to +3.
Description
Technical field
The present invention relates to a kind of numerical control relief-grinding machine workpiece head-rest, belong to the machining equipment technical field.
Background technology
Hobboing cutter is specific purpose tools such as machining gear, worm gear, sprocket wheel.Along with high class gear popularize to use, the profile of tooth, pitch, helix accuracy that require hobboing cutter in micron order, the profile of tooth of hobboing cutter be with machine for relief grinding step by step reconditioning come out.Original machine for relief grinding makes hobboing cutter carry out calibration off and on to each tooth relief grinding in a helical pitch by general screw mandrel, cam and many gears, change gear transmission, and its precision is all lower.Experience and corresponding instrument with the operator constantly detects entirely, so working (machining) efficiency is very low, numerical control relief-grinding bed reconditioning hob profile is more satisfactory equipment.Workhead---that is to say the calibration panoramic table, is numerical control relief-grinding bed vitals, and it generally uses the transmission of precise worm worm gear pairs, sets 0.001 ° of minimum calibration unit, indexing accuracy 〉=20 ", can't use for this precision of numerical control relief-grinding bed is too low.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of numerical control relief-grinding machine workpiece head-rest is provided, eliminated return difference and accumulated error that original worm and wormwheel is paid transmission, calibration accuracy height, the headstock stability of rotation of transmission workpiece rotation.
Main solution of the present invention is achieved in that
The present invention mainly adopts motor stator to be fixed in the headstock body apertures, rotor is fixed on the main shaft, bearing is installed in the main shaft lower end, bearing outer ring is contained in the side cover hole, and bearing is installed in the main shaft upper end, and bearing outer ring is contained in the loam cake hole, oil sealing lining, dial, loam cake are installed on the main shaft respectively, at main-axis end oil sealing is installed, the top alignment of shafts that is installed in, garden shape angular encoder is sleeved on the main shaft end.
Described bearing surface opposite angular contact is installed.Described bearing back to back angle contact is installed.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; To eliminate original worm and wormwheel and paid the return difference and the accumulated error of transmission, the calibration accuracy reaches ± and 2 " in, axial runout＜0.005 μ m; High accuracy hob profile, pitch, front edge helix error in several microns, the headstock stability of rotation of transmission workpiece rotation, 0.0001 ° of step pitch is measured in calibration accuracy≤± 3.
