Abstract
The utility model relates to a double-center hobbing jig for hobbing machines. According to the technical scheme, the double-center hobbing jig comprises a bottom board, a steel ball, at least three pressure plates, connecting bolts and puller bolts, wherein the bottom board is fixed on a hobbing bench of a hobbing machine, a lower center hole is arranged in the center of the bottom board, the steel ball as a lower center is disposed inside the lower center hole, each pressure plate is connected onto the upper surface of the bottom board through the bolts penetrating through the middle of the pressure plate, the three pressure plates are uniformly distributed in the circumferential direction, the head of each pressure plate faces the center of the bottom board to press a workpiece, and the tail of each pressure plate is connected with one puller bolt which is downwardly supported on the bottom board. The double-center hobbing jig is simple and smart in structure, and safe and reliable in clamping, can greatly reduce operational difficulty, highly increases production efficiency, and ensures fine machining precision of workpieces.
Description
Technical field
The utility model belongs to machining manufacturing technology field, the two top gear hobbing frocks that specifically relate to use on a kind of gear-hobbing machine.
Background technology
General hobbing machine adopts folder top mode mostly when the working shaft-like part, promptly the workpiece lower end clamps by frock or chuck, and the upper end holds out against with the tailstock centre on the gear-hobbing machine.When clamping, by the centering cylindrical guarantee workpiece upper and lower two sections with one heart.Such installation way is had relatively high expectations to the operative employee's, sometimes the calibration of workpieces time is very long, cause production efficiency low, even upper and lower two place's corrections place can occur and can not reach the phenomenon of technological requirement simultaneously, thereby cause the roll flute surplus to increase or beat excessive and produce and scrap in final footpath.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple and ingenious structure, the reliable gear-hobbing machine two top gear hobbing frocks of fastening safety are provided, this frock can reduce operation easier greatly, improves production efficiency, and guarantees that the workpiece machining accuracy is good.
According to the technical scheme that the utility model provides, described gear-hobbing machine two top gear hobbing frocks comprise base plate, steel ball, pressing plate, connecting bolt and puller bolt; Described base plate is fixed on the gear hobbing workbench of gear-hobbing machine, offers center hole down at the center of base plate, is used to place conduct top steel ball down in the following center hole; Described pressing plate has three at least, and every block pressur plate all utilizes the bolt that passes its middle part to be connected on the upper surface of base plate; Described at least three block pressur plates evenly distribute in a circumferential direction, and the head of every block pressur plate is used to push down workpiece towards the center of base plate; The afterbody of every block pressur plate connects puller bolt, and puller bolt is supported on the base plate downwards.
As further improvement of the utility model, described pressing plate is three.
As further improvement of the utility model, offer fixing hole on the described base plate, the bolt that this fixing hole is passed in the base plate utilization is fastened on the gear hobbing workbench.
As further improvement of the utility model, described pressing plate is a rectangle.
As further improvement of the utility model, described steel ball is as top use down, and it is positioned in the workpiece centre hole.
Clamping frock when the utility model is the axial workpiece gear hobbing, it compared with prior art, advantage is: simple and ingenious structure, rationally utilized the centre bore on the workpiece, need not go the external diameter of calibration of workpieces to beat again, can reduce the human factor of timing, effectively reliably fixation workpiece, improve the stability of crudy greatly, enhance productivity.Base plate in the utility model can be selected according to the tooth axle of the different diameters of axle flexibly with clamping plate, and is applied widely and manufacturing cost is lower.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the gear-hobbing machine two top gear hobbing frocks among the embodiment mainly comprise parts such as base plate 1, puller bolt 2, connecting bolt 3, pressing plate 4 and steel ball 6; Offer fixing hole 8 on the described base plate 1, base plate 1 utilizes the bolt that passes this fixing hole 8 to be fastened on the gear hobbing workbench; Offer center hole 7 down at the center of base plate 1, be used to place conduct top steel ball 6 down in the following center hole 7; Described pressing plate 4 has three, and every block pressur plate 4 all utilizes the connecting bolt 3 that passes its middle part to be connected on the upper surface of base plate 1; Three block pressur plates 4 evenly distribute in a circumferential direction, and three block pressur plates 4 are rectangle, and the head of every block pressur plate 4 is used to push down workpiece 5 towards the center of base plate 1; The afterbody of every block pressur plate 4 connects puller bolt 2, and puller bolt 2 is supported on downwards on the base plate 1.
Operation principle of the present utility model is as follows:
At first proofread and correct base plate 1 cylindrical and plane, guarantee that center hole 7 is coaxial with tailstock center down, get final product fixed base plate 1; Steel ball 6 is put into the following center hole 7 of base plate 1, steel ball 6 is top down as one, put into workpiece 5 then, the centre bore of workpiece 5 one ends is corresponding with steel ball 6, and steel ball 6 is positioned in the centre bore of workpiece 5, and workpiece 5 other ends push up appropriate by tailstock center; Turn connecting bolt 3 then downwards, because the afterbody of pressing plate 4 withstands by puller bolt 2, when connecting bolt 3 was descending, the head end of pressing plate 4 evenly compressed workpiece 5.Here be noted that and push up appropriate clamping work pieces again 5 earlier that polylith pressing plate 4 should be stressed even during clamping work pieces 5.
