Description
Technical field
The present invention relates to spiral bevel gear endoporus Vehicle Processing technology, be related specifically to a kind of Vehicle Processing spiral bevel gear internal clamp.
Background technology
Transmission efficiency is high, gearratio stable, circular arc overlap coefficient is large and bearing capacity high, is widely used in each mechanical field because it has for spiral bevel gear.In the process manufacturing spiral bevel gear, first to produce profile and spiral bevel gear shows conical surface annulus, then conical surface annulus is fixed on the work top of gear-hobbing machine or tooth milling machine, then, carry out mill teeth or gear hobbing process.Because the face of mill teeth or gear hobbing process is on the surface of conical surface annulus, therefore, clamping processing can only be carried out by step in conical surface annulus or medial surface.This method of clamping is easily eccentric, or journal offset, and the centre of pitch circle of the helical tooth after making Milling Machining or rolling processing and the endoporus center of whole gear be not at same point.Need to process the endoporus of bolt bevel gear, endoporus center is overlapped with the centre of pitch circle of helical tooth.Prior art spiral bevel gear endoporus turning processing method adopts the cylindrical of scroll chuck clamping spiral bevel gear to process, cylindrical due to spiral bevel gear inherently may exist with the centre of pitch circle of helical tooth and offsets, therefore, with the endoporus of spiral bevel gear excircle orientation processing, be also difficult to ensure that the endoporus center of spiral bevel gear overlaps with the centre of pitch circle of helical tooth.Obviously, prior art spiral bevel gear endoporus turning processing method also exists with spiral bevel gear excircle orientation, is difficult to ensure the endoporus center of spiral bevel gear and the problem such as the centre of pitch circle of helical tooth overlaps.
Summary of the invention
For solve that prior art spiral bevel gear endoporus turning processing method exists with spiral bevel gear excircle orientation, be difficult to ensure the endoporus center of spiral bevel gear and the problem such as the centre of pitch circle of helical tooth overlaps, the present invention proposes a kind of Vehicle Processing spiral bevel gear internal clamp.
Vehicle Processing spiral bevel gear internal clamp of the present invention, comprises substrate, location-plate, locating dowel and hold-down mechanism; Disc substrate is fixed on platen face, disc location-plate is dismountable is fixed on substrate surface with one heart, the locating dowel of more than six or six be evenly distributed on centered by the location-plate center of circle with the central point between spiral bevel gear endoporus and cylindrical apart from the substrate center of circle distance for radius circumferentially; Tooth pitch and the profile of tooth size of the spacing of locating dowel and tip shapes and spiral bevel gear match; Outside location-plate, substrate is circumferentially evenly provided with the hold-down mechanism of more than three or three; The tooth pitch of the spacing of described locating dowel and tip shapes and spiral bevel gear and profile of tooth size match and refer to that spiral bevel gear tips upside down on after in locating dowel, and the termination of locating dowel can both enter into tooth root, and spiral bevel gear can not planar movement again.
Further, described hold-down mechanism comprises pressure head and piston-cylinder, and described pressure head is fixed on piston rod end, and described cylinder piston can 90 degree of rotations when moving up and down.
The Advantageous Effects of Vehicle Processing spiral bevel gear internal clamp of the present invention is can with the pitch circle of spiral bevel gear for benchmark, spiral bevel gear is firmly fixed on the work top of lathe, the location of the spiral bevel gear of the different number of teeth or modulus can be adapted to and fix, and, easy to loading and unloading.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic three dimensional views of Vehicle Processing spiral bevel gear internal clamp of the present invention;
Accompanying drawing 2 is the schematic three dimensional views after Vehicle Processing spiral bevel gear internal clamp of the present invention clamping spiral bevel gear.
Below in conjunction with the drawings and specific embodiments, Vehicle Processing spiral bevel gear internal clamp of the present invention is further described.
Detailed description of the invention
Accompanying drawing 1 is the schematic three dimensional views of spiral bevel gear endoporus workpiece machining clamp of the present invention, accompanying drawing 2 is the schematic three dimensional views after spiral bevel gear endoporus workpiece machining clamp of the present invention clamping spiral bevel gear, in figure, 1 is substrate, 2 is location-plate, and 3 is locating dowel, and 4 is pressure head, 5 is cylinder, and A is spiral bevel gear.As seen from the figure, Vehicle Processing spiral bevel gear internal clamp of the present invention, comprises substrate 1, location-plate 2, locating dowel 3 and hold-down mechanism; Disc substrate 1 is fixed on platen face, disc location-plate 2 is dismountable is fixed on substrate 1 surface with one heart, the locating dowel 3 of more than six or six be evenly distributed on centered by the location-plate center of circle with the central point between spiral bevel gear endoporus and cylindrical apart from the substrate center of circle distance for radius circumferentially; Tooth pitch and the profile of tooth size of the spacing of locating dowel and tip shapes and spiral bevel gear match; Outside location-plate, substrate is circumferentially evenly provided with the hold-down mechanism of more than three or three; The spacing of described locating dowel 3 and the tooth pitch of tip shapes and spiral bevel gear and profile of tooth size match and refer to that spiral bevel gear tips upside down on after in locating dowel, and the termination of locating dowel can both enter into tooth root, and spiral bevel gear can not planar movement again.Wherein, described hold-down mechanism comprises pressure head and piston-cylinder, and described pressure head is fixed on piston rod end, and described cylinder piston can 90 degree of rotations when moving up and down.When specifically using, the spiral bevel gear of endoporus to be processed is tipped upside down in locating dowel, because the termination of locating dowel can both enter into tooth root, and spiral bevel gear can not planar movement again, spiral bevel gear is located accurately, is in fact exactly the location that is benchmark with the pitch circle of spiral bevel gear.Open cylinder, cylinder piston moves down and 90 degree of rotations, makes pressure head be pressed in the spiral bevel gear back side, thus, is clamped by spiral bevel gear and fix.Substrate surface is fixed on one heart because location-plate is dismountable, if when needing the spiral bevel gear fixing another modulus or the number of teeth, location-plate can be unloaded together with locating dowel, change a location-plate and locating dowel that can match with the spiral bevel gear of another kind of modulus or the number of teeth, just can carry out clamping and processing.
Obviously, the Advantageous Effects of Vehicle Processing spiral bevel gear internal clamp of the present invention is can with the pitch circle of spiral bevel gear for benchmark, spiral bevel gear is firmly fixed on the work top of lathe, the location of the spiral bevel gear of the different number of teeth or modulus can be adapted to and fix, further, easy to loading and unloading.
