Abstract
The utility model discloses a bevel gear pitch circle positioning fixture comprising a locating structure, a lever structure and a driving structure. The locating structure comprises a pipe frame, a connecting disk, a locating disk, a locating plate and a locating pin, wherein the locating pin is equally divided according to the pitch circle diameter and installed on the right end surface of the locating plate. The lever structure comprises a translation lever and a tension arm with both ends connected by a pin hinge, an elongated slot at the middle section of the tension arm takes pins arranged at two sides of the locating disk as fulcrums, and the right end of the tension arm is connected with a tension jaw. The driving structure utilizes a worm wheel and a worm gear to interact a lead screw and a nut plate, and the translation lever which is in clearance fit with the lead screw moves along with the nut plate under the push of a spring. The lead screw takes the centers of the connecting disk and the locating disk as supporting points, the outer wall of the pipe frame is provided with a radial opening groove to limit the translation lever and the nut plate to move, and the lead screw rotates along with the worm wheel so that the translation lever and the nut plate move to drive the lever structure to act. The utility model has consistent location and design standard, accurate and reliable location, and meets the requirement for mass production.
Description
Technical field
The utility model relates to a kind of machined positioning fixture, particularly a kind of anchor clamps of locating grinding sheet bevel gear endoporus.
Background technology
Bevel gear is a common part in the gearing, and the sheet bevel gear is a kind of bevel gear that matches with power transmission shaft, and its design feature is mainly reflected in the design basis that endoporus is a bevel gear, also is the location benchmark, the quality of the direct cone of influence gear of endoporus precision.Carrying out inner hole grinding processing after the bevel gear heat treatment is the necessary operation that realizes precision, and prior art generally adopts three melon self-centering chucks to do cylindrical location and clamping.Although easy, the easy realization of the method, its location benchmark and design basis are inconsistent, easily produce position error, and the positional precision that constitutes bevel gear pitch circle and endoporus can't accurately be controlled, and can not guarantee crudy.
The utility model content
The utility model is primarily aimed at prior art when the grinding worm endoporus, the shortcoming of location benchmark and the inconsistent easy generation position error of design basis, propose a kind of simple in structure, location reliably, the bevel gear pitch circle positioning fixture of datum coincidence, convenient mounting and clamping.
The utility model is achieved through the following technical solutions technical goal.
Bevel gear pitch circle positioning fixture, it comprises location structure, lever construction and drive mechanism.Described location structure comprises horizontally-arranged cylindrical shape pipe support, with and the positioning disk that is connected with right-hand member of the terminal pad that connects of left end, positioning disk right-hand member endoporus is equipped with location-plate.Described lever construction comprises the arm of force that translation bar and two ends thereof are hinged by pin, and arm of force stage casing elongated slot is a fulcrum with the pin that is located at the positioning disk both sides, and arm of force right-hand member connects crooked pulling claw inwardly.Described transmission mechanism contains the screw mandrel and the nutplate of worm couple and interlock thereof, moves with nutplate under spring promotes with the translation bar of screw mandrel matched in clearance.Its improvements are: the screw mandrel two ends are supporting-point with the center of terminal pad and positioning disk respectively, pipe support outer arm left end is provided with the radial opening groove, the two ends of translation bar and nutplate are inserted in the radial opening groove of pipe support, and screw mandrel makes translation bar and nutplate do to move axially with worm gear rotation and affects the lever construction action.Described shop bolt is made 3～6 five equilibriums by pitch diameter and is vertically mounted on the location-plate right side.
In the said structure, shop bolt is vertically mounted on the location-plate right side with the pitch diameter five equilibrium, and the shop bolt head is a truncated cone, and its vertex of a cone place is a spheroid, and each sphere diameter equates that ball top to location-plate right side distance equates.
The utility model compared with prior art has the following advantages:
1, with the pitch circle location grinding endoporus of bevel gear, its location benchmark is consistent with design basis, does not have position error, accurate positioning;
2, affect the lever construction workpiece pressing by worm couple, compress reliable with interlocking capability;
3, convenient mounting and clamping is convenient to grinding, satisfies requirement of mass production.
Description of drawings
Accompanying drawing is the utility model structural profile schematic diagram.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Bevel gear pitch circle positioning fixture shown in the drawings, it comprises location structure, lever construction and drive mechanism.Described location structure is an agent structure, comprise horizontally-arranged cylindrical shape pipe support 12 with and the positioning disk 9 that is connected with right-hand member of the terminal pad 1 that connects of left end, positioning disk 9 right-hand member endoporus are equipped with location-plate 8, dowel pin 6 is vertically mounted on location-plate 8 right sides by the pitch diameter five equilibrium, be provided with the shop bolt 6 that 3 five equilibriums are installed in the present embodiment, shop bolt 6 heads are truncated cone, and the truncation position is provided with spheroid, each sphere diameter equates that ball top to location-plate 8 right sides distance equates.Described lever construction comprises the arm of force 4 that translation bar 2 and two ends thereof are hinged by pin 3, and the arm of force 4 stage casing elongated slots are fulcrum with the pin 5 that is located at positioning disk 9 both sides, and the arm of force 4 right-hand members connect crooked pulling claw 7 inwardly.Described transmission mechanism is installed in the middle part, and transmission mechanism be main component interlock screw mandrel 13 and nutplate 11 with worm and gear 10, moves with nutplate 11 under spring 14 promotions with the translation bar 2 of screw mandrel 13 matched in clearance.Among the embodiment, screw mandrel 13 two ends are supporting-point with the center of terminal pad 1 and positioning disk 9 respectively, pipe support 12 outer wall left ends are provided with the radial opening groove, in the radial slot of the two ends straight cutting pipe support 12 of translation bar 2 and nutplate 11, screw mandrel 13 makes translation bar 2 and nutplate 11 do to move axially with worm gear rotation and affects the lever construction action.Translation bar 2 and nutplate 11 move axially left, and pulling claw 7 compresses processed bevel gear under the affecting of the arm of force 4, can load and unload processed bevel gear otherwise then unclamp.The utility model is with the pitch circle location grinding endoporus of bevel gear, solved processing location benchmark and the inconsistent problem of design basis, affected lever construction to compress processed bevel gear with worm couple 10 simultaneously, compressed reliable with interlocking capability, convenient mounting and clamping satisfies requirement of mass production.
