Description
Technical field
The utility model relates to spiral bevel gear endoporus Vehicle Processing technology, specially refers 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 because it has for spiral bevel gear, is widely used in each mechanical field. Manufacturing in the process of spiral bevel gear, first to produce profile and spiral bevel gear and show 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 processing. Because the face of mill teeth or gear hobbing processing is on the surface of conical surface annulus, therefore, can only clamp processing by the interior step of conical surface annulus or medial surface. This method of clamping is easily eccentric, or journal offset, make milling processing or roll the centre of pitch circle of the helical tooth after processing and the endoporus center of whole gear 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, because the cylindrical of spiral bevel gear itself just may exist skew with the centre of pitch circle of helical tooth, 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 exists with spiral bevel gear excircle orientation, the endoporus center that is difficult to ensure 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, the endoporus center that is difficult to ensure spiral bevel gear and the problem such as the centre of pitch circle of helical tooth overlaps, the utility model proposes a kind of Vehicle Processing spiral bevel gear internal clamp.
The utility model Vehicle Processing spiral bevel gear internal clamp, comprises substrate, location-plate, locating dowel and hold-down mechanism; Disc substrate is fixed on platen face, the dismountable substrate surface that is fixed on one heart of disc location-plate, the above locating dowel of six or six is evenly distributed on distance taking the central point between spiral bevel gear endoporus and cylindrical apart from the substrate center of circle on the circumference of radius centered by the location-plate center of circle; The tooth pitch of the spacing of locating dowel and termination shape and spiral bevel gear and profile of tooth size match; Outside location-plate, on substrate circumference, be evenly provided with more than three or three hold-down mechanisms; After the tooth pitch of the spacing of described locating dowel and termination shape and spiral bevel gear and profile of tooth size match and refer to that spiral bevel gear tips upside down in locating dowel, the termination of locating dowel can both enter into tooth root, and spiral bevel gear is 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 rotations in the time moving up and down.
The useful technique effect of the utility model Vehicle Processing spiral bevel gear internal clamp is can be taking the pitch circle of spiral bevel gear as benchmark, spiral bevel gear is firmly fixed on the work top of lathe, the location of the spiral bevel gear of the energy different numbers of teeth of adaptation or modulus and fixing, and, easy to loading and unloading.
Brief description of the drawings
Accompanying drawing 1 is the schematic three dimensional views of the utility model Vehicle Processing spiral bevel gear internal clamp;
Accompanying drawing 2 is the schematic three dimensional views after the utility model Vehicle Processing spiral bevel gear internal clamp clamping spiral bevel gear.
Below in conjunction with the drawings and specific embodiments, the utility model Vehicle Processing spiral bevel gear internal clamp is further described.
Detailed description of the invention
Accompanying drawing 1 is the schematic three dimensional views of the utility model spiral bevel gear endoporus workpiece machining clamp, accompanying drawing 2 is the schematic three dimensional views after the utility model spiral bevel gear endoporus workpiece machining clamp 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, the utility model Vehicle Processing spiral bevel gear internal clamp, comprises substrate 1, location-plate 2, locating dowel 3 and hold-down mechanism; Disc substrate 1 is fixed on platen face, dismountable substrate 1 surface that is fixed on one heart of disc location-plate 2, the above locating dowel 3 of six or six is evenly distributed on distance taking the central point between spiral bevel gear endoporus and cylindrical apart from the substrate center of circle on the circumference of radius centered by the location-plate center of circle; The tooth pitch of the spacing of locating dowel and termination shape and spiral bevel gear and profile of tooth size match; Outside location-plate, on substrate circumference, be evenly provided with more than three or three hold-down mechanisms; After the tooth pitch of the spacing of described locating dowel 3 and termination shape and spiral bevel gear and profile of tooth size match and refer to that spiral bevel gear tips upside down in locating dowel, the termination of locating dowel can both enter into tooth root, and spiral bevel gear is 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 rotations in the time moving up and down. In the time of concrete use, 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 is planar movement again, spiral bevel gear is located accurately, is exactly in fact the location taking the pitch circle of spiral bevel gear as benchmark. Open cylinder, cylinder piston moves down and 90 degree rotations, makes pressure head be pressed in the spiral bevel gear back side, thus, spiral bevel gear is clamped and is fixed. Be fixed on one heart substrate surface because location-plate is dismountable, if need to fix the spiral bevel gear of another modulus or the number of teeth time, location-plate can be unloaded together with locating dowel, change location-plate and a locating dowel that can match with the spiral bevel gear of another kind of modulus or the number of teeth, just can clamp and process.
Obviously, the useful technique effect of the utility model Vehicle Processing spiral bevel gear internal clamp is can be taking the pitch circle of spiral bevel gear as benchmark, spiral bevel gear is firmly fixed on the work top of lathe, the location of the spiral bevel gear of the energy different numbers of teeth of adaptation or modulus and fixing, and, easy to loading and unloading.
