The utility model discloses a reasonable structure can realize that device design is reasonable in the purpose of ordinary processing equipment middle finishing high accuracy ARC end tooth, and the adjustment is convenient, cost -effective target can be realized to the different position sleeve of design.
Description
Technical field
The utility model relates to a kind of clamp, especially a kind of circular arc end tooth clamp.
Background technology
In mechanical rotor structure, often adopt this high-accuracy end face spline structure of circular arc end tooth, this structure has the advantage that the accuracy of mesh is high, self-centering good, transmitting torque is large.The processing of circular arc end tooth is by fixture positioning and clamping, and utilizes the cup emery wheel of High Rotation Speed on the end face of part directly by circular arc type end tooth grinding forming.Current machining high-precision circular arc end tooth requires that equipment precision is very high, and is equipped with high-precision special fixture and could realizes.Special fixture possesses self-centering function usually, as centering of expanding, taper fit centering, small―gap suture coordinate centering etc.And the processing that this fixture requires and quality of fit very high, just can reach the object of high-precision arc end tooth processing, but for the lower process equipment of some precision, the processing of high-precision arc end tooth be realized, then need more high-precision fixture, be difficult to even sometimes realize.Meanwhile, this self centering fixture, can only process the part of a certain class, and when part is different, then need to redesign and a set of special fixture of processing and manufacturing, complex process, cost are high.
Summary of the invention
The purpose of this utility model is to provide a kind of circular arc end tooth clamp, and this fixture has the advantages that technique is simple, cost is low, and can realize the object realizing the processing of high-precision arc end tooth on conventional equipment.
Concrete technical scheme of the present utility model is, described circular arc end tooth clamp comprises clamp body, positioning sleeve, housing screw, directed latch, adjustment screw, the center of described clamp body is arranged porose, the upper end in hole is provided with step, lower end is provided with screw thread, the bottom of positioning sleeve coordinates and is arranged on the step of the upper end in hole, the top of positioning sleeve can coordinate part to be processed is installed seam on; Described housing screw, through after the centre bore of part to be processed and positioning sleeve, is arranged on the screw thread of clamp body centre bore bottom, and is compressed by part to be processed; Described clamp body upper end face part is provided with directional hole in the position in part angle hole to be processed, and described directed latch, after the insertion on part top to be processed, coordinates with angle hole and directional hole respectively; Clamp body bottom is provided with through hole and is provided with adjustment screw, and described adjustment screw can withstand on the equipment workbench of clamp body installation.Arrange the ejector pin that can move axially in described clamp body lower through-hole, described ejector pin two ends withstand on adjustment screw and equipment workbench respectively.
Clamp body in use, is positioned on the workbench of equipment by the utility model, rotates adjustment screw, and on the table, by adjustment, after the form and position tolerance making clamp body upper surface reach required, geometrical clamp is concrete on ejector pin top; Be arranged on by positioning sleeve on clamp body, gear cooperation to be processed is arranged on clamp body top, rotates part to be processed and makes the directional hole of its angle hole line-up jig body insert directed latch, and compressed by housing screw, can treat machining gears and carry out roughing.During fine finishining, in the gear teeth first angle phase length bar is put into roughing before the screw that is fixed and clamped after, with the stretching centering of amesdial, after adjustment lathe of work level angle, be fixed and clamped screw, carries out fine finishining.The utility model realizes the angle location of gear to be processed by directed latch, and adjustment screw realizes the installation accuracy in Gear Processing face to be processed.Meanwhile, according to different parts, corresponding positioning sleeve can being processed, by changing positioning sleeve, realizing the versatility of fixture; The effect of ejector pin is when adjusting, and avoids adjustment screw and workbench to rub to produce and offset, thus affects Adjustment precision.The utility model, by rational structure, can be implemented in the object of machining high-precision circular arc end tooth in common process equipment, and apparatus design is reasonable, easy to adjust; Design different positioning sleeves, cost-saving target can be realized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in the figure, circular arc end tooth clamp comprises clamp body 3, positioning sleeve 5, housing screw 6, directed latch 4, adjustment screw 2, the center of described clamp body 3 is arranged porose, the upper end in hole is provided with step, lower end is provided with screw thread, the bottom of positioning sleeve 5 coordinates and is arranged on the step of the upper end in hole, the top of positioning sleeve 5 can coordinate part 8 to be processed is installed seam on; Described housing screw 6, through after the centre bore of part 8 to be processed and positioning sleeve 5, is arranged on the screw thread of clamp body 3 centre bore bottom, and is compressed by part 8 to be processed; Described clamp body 3 upper end face part is provided with directional hole in the position in part 8 angle hole to be processed, and described directed latch 4, after the insertion on part top to be processed, coordinates with angle hole and directional hole respectively; Clamp body 3 bottom is provided with through hole and is provided with adjustment screw 2, and described adjustment screw 2 can withstand on the equipment workbench of clamp body 3 installation.Arrange the ejector pin 1 that can move axially in described clamp body 3 lower through-hole, described ejector pin two ends withstand on adjustment screw 2 and equipment workbench respectively.
