Abstract
The utility model discloses a boring and milling head special for inclination angles, which comprises a milling head main shaft with a taper hole for mounting tools arranged at one end and a driven bevel gear mounted at the other end, the milling head main shaft is disposed inside a milling head casing body, the driven bevel gear meshes with a drive bevel gear, the shaft angle formed by the driven bevel gear and the drive bevel gear is larger than 0 degree and smaller than 90 degrees, the drive bevel gear is mounted at the lower end of a transmission vertical shaft, the upper end of the transmission vertical shaft is connected with a main shaft of a vertical lathe tool holder, and the milling head casing body is connected with the vertical lathe tool holder. The boring and milling head special for inclination angles is mounted on a vertical lathe tool holder, can rotate 360 degrees in horizontal direction, and is special for processing slant holes, platforms, rabbets and the like with certain inclination angles. After each rotary surface of a work piece finishes process on the vertical lathe, slant holes, slant faces and inclination rabbets of the work piece can be directly processed, avoiding process errors caused by changing processing machines for the work piece, saving secondary clamping and centering time of the work piece, and improving the process quality and efficiency of work pieces.
Description
Technical field
The utility model relates to a kind of milling head, particularly relates to a kind of inclination angle ° special-purpose boring and milling head outer.
Background technology
At present, the inclined hole on the small processing part normally utilizes universal milling head processing on the milling machine or utilizing frock to process on boring machine.Reach 5 meters to 15 meters large-scale workpiece for diameter, the surface of revolution is processed on large-scale vertical lathe usually, but the special machine bed still useless so far of the inclined hole on the aforementioned large-scale workpiece, and the general milling head that also is not equipped with the boring and milling inclined hole of large-scale vertical lathe are equipped with 90 ° of milling heads peace milling heads usually.Therefore the inclined hole of machining large workpiece becomes a current processing difficult problem.
Summary of the invention
The utility model provides a kind of special-purpose boring and milling head outer that can process inclination angle ° inclined hole for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the special-purpose boring and milling head outer in a kind of inclination angle, comprise that an end is provided with the milling head main shaft of the taper hole that is used for mounting cutter, the milling head main shaft is installed in the milling head casing, the other end of described milling head main shaft is equipped with driven wheel of differential, described driven wheel of differential engagement drive bevel gear, the crossed axis angle of described drive bevel gear and driven wheel of differential greater than 0 ° less than 90 °, described drive bevel gear is installed in the lower end of transmission vertical shaft, the upper end of described transmission vertical shaft is connected with the vertical lathe tool spindle, and described milling head casing is connected on the vertical lathe knife rest.
The crossed axis angle of described drive bevel gear and driven wheel of differential is 30 °.
Described bevel gear is a straight bevel gear.
Described milling head casing upper end is provided with the gear ring that is used for being provided with the affixed upper end of vertical lathe knife rest tooth.
Described milling head casing top is provided with annular T type groove, is provided with connecting bolt in the described T type groove, and described milling head casing is connected by connecting bolt with gear ring.
Advantage and the good effect that the utlity model has are: be contained on the vertical lathe knife rest, horizontal direction can 360 ° of rotations.Be specifically designed to processing and have the inclined hole, platform, seam etc. at certain inclination angle.Workpiece is after the processing of finishing each rotary surface on the vertical lathe, utilize this milling head, can directly carry out inclined hole, inclined-plane, the tiltedly processing of seam of workpiece, avoided workpiece to change the mismachining tolerance that machining tool brings once more, save the workpiece secondary clamping centering time, improved the crudy and the efficient of workpiece.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, fluted disc, 2, the milling head casing, 3, drive bevel gear, 4, the milling head main shaft, 5, driven wheel of differential, 6, the transmission vertical shaft.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, after on 15 meters and 6.3 meter numerical control vertical lathes, finishing the processing of each rotary surface of workpiece, be used for boring and milling special angle inclined hole, seam, the special-purpose boring and milling head outer in a kind of inclination angle that the platform specialized designs is made, comprise that an end is provided with the milling head main shaft 4 of the taper hole that is used for mounting cutter, milling head main shaft 4 is installed in the milling head casing 2, the other end of described milling head main shaft 4 is equipped with driven wheel of differential 5, described driven wheel of differential 5 engagement drive bevel gear 3, described drive bevel gear 3 is 30 ° with the crossed axis angle of driven wheel of differential 5, described drive bevel gear 3 is installed in the lower end of transmission vertical shaft 6, the upper end of described transmission vertical shaft 6 has keyway, connect with the vertical lathe tool spindle with flat key, described milling head casing 2 is connected on the vertical lathe knife rest.Described drive bevel gear 3 is not limited in 30 ° with the crossed axis angle of driven wheel of differential 5, and it can should equate with the angle of inclination of working position for greater than 0 ° of unspecified angle less than 90 °.
Described bevel gear considers that manufacturing cost can be a straight bevel gear.
Described milling head casing 2 upper ends are provided with the gear ring 1 that is used for being provided with the affixed upper end of vertical lathe knife rest 120 teeth.Fluted disc and vertical lathe knife rest link.Fluted disc 1 bottom be provided with one with the seam of milling head casing 2 location.Milling head casing 2 tops have annular T type groove.Milling head can be felt relieved 360 ° of rotations by the fluted disc seam.Unclamp the nut on the connecting bolt during adjustment, move connecting bolt along annular T type groove, thereby realize that the milling head casing moves along the revolution of annular T type groove, after moving into place, locking nut can be processed inclined hole, seam, the plane of all size.
Biserial cylindrical roller bearing and thrust bearing are housed respectively before and after the milling head main shaft.The running accuracy height, output torque is big.
