Abstract
The utility model discloses spiral bevel gear hole boring machining anchor clamps, including base plate, reference column and hold -down mechanism, ring shape base plate is fixed on the machine tool table face, and reference column more than six or six uses the base plate centre of a circle and is using on central point between spiral bevel gear hole and the excircle is radial circumference apart from the distance in the base plate centre of a circle for central evenly distributed, the interval of reference column and end shape and spiral bevel gear's tooth pitch and profile of tooth size phase -match, evenly be provided with the hold -down mechanism more than three or three on the circumference of the outside of reference column, the interval of reference column and end shape and spiral bevel gear's tooth pitch and profile of tooth size phase -match are spiral bevel gear back -off backs on the reference column, and the end of reference column can both enter into the tooth root to, spiral bevel gear plane again removes. The utility model discloses the pitch circle that can use spiral bevel gear is as the benchmark, with firm the fixing on the table surface of lathe of spiral bevel gear to, loading and unloading are convenient.
Description
Technical field
The utility model relates to spiral bevel gear endoporus boring process technology, specially refers to a kind of spiral bevel gear endoporus boring clamp for machining.
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 spiral 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 boring 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 spiral bevel gear endoporus boring clamp for machining.
The utility model spiral bevel gear endoporus boring clamp for machining, comprises substrate, locating dowel and hold-down mechanism; Annular substrate is fixed on platen face, and 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 substrate 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; In the outer circumference of locating dowel, 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 column, depression bar and piston-cylinder, and described column is fixed on substrate, and the middle part of depression bar is hinged on column termination, and the substrate center of circle is pointed in one end of depression bar, and the other end and piston rod end are hinged; Cylinder is arranged on substrate bottom surface.
The useful technique effect of the utility model spiral bevel gear endoporus boring clamp for machining is taking the pitch circle of spiral bevel gear as benchmark, spiral bevel gear to be firmly fixed on the work top of lathe, and, easy to loading and unloading.
Brief description of the drawings
Accompanying drawing 1 is the schematic three dimensional views of the utility model spiral bevel gear endoporus boring clamp for machining;
Accompanying drawing 2 is the schematic three dimensional views after the utility model spiral bevel gear endoporus boring clamp for machining clamping spiral bevel gear.
Below in conjunction with the drawings and specific embodiments, the utility model spiral bevel gear endoporus boring clamp for machining 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 boring clamp for machining, accompanying drawing 2 is the schematic three dimensional views after the utility model spiral bevel gear endoporus boring clamp for machining clamping spiral bevel gear, in figure, 1 is substrate, 2 is locating dowel, and 31 is column, and 32 is depression bar, 33 is piston rod, and A is spiral bevel gear. As seen from the figure, the utility model Vehicle Processing spiral bevel gear internal clamp, comprises substrate 1, locating dowel 2 and hold-down mechanism; Annular substrate 1 is fixed on platen face, and the above locating dowel 6 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 substrate center of circle; The tooth pitch of the spacing of locating dowel 2 and termination shape and spiral bevel gear and profile of tooth size match; In the outer circumference of locating dowel 2, 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. Wherein, described hold-down mechanism comprises column, depression bar and piston-cylinder, and described column is fixed on substrate, and the middle part of depression bar is hinged on column termination, and the substrate center of circle is pointed in one end of depression bar, and the other end and piston rod end are hinged; Cylinder is arranged on substrate bottom surface. When 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, opens cylinder, piston promotes depression bar, and spiral bevel gear is fixedly positioning and clamped.
Obviously, the useful technique effect of the utility model spiral bevel gear endoporus boring clamp for machining is taking the pitch circle of spiral bevel gear as benchmark, spiral bevel gear to be firmly fixed on the work top of lathe, and, easy to loading and unloading.
