Technical field
The invention belongs to external toothing manufacture field, particularly relate to a kind of external toothing pressing method.
Background technology
At present, be all first be fixed on gear-hobbing machine by single gear ring at the periphery upper rolling tooth of external toothing, then carry out gear hobbing, working (machining) efficiency is low, is badly in need of solving above-mentioned technical barrier for this reason.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of external toothing pressing method, for improving gear hobbing efficiency.
Technical scheme of the present invention is as follows: a kind of external toothing pressing method, is characterized in that comprising the steps:
Step a a: press-fitting tool is set, this press-fitting tool is made up of upper moving assembly and lower positioning component, wherein: described upper moving assembly comprises pressure ring (3) under horizontal pressure foot (1) and level, wherein go up horizontal pressure foot (1) coaxially to fix with the pressure head (YT) of press (Y), on this, the lower face of horizontal pressure foot (1) is coaxially fixed by one group of vertical joint pin (2) and pressure ring (3) end face under described level, and this vertical joint pin is circumferentially arranged;
The axial line of described lower positioning component and upper moving assembly is on same straight line, and comprise lower positioning seat (4) and lower cover (7), wherein: described lower positioning seat (4) is fixed on the workbench (YG) of described press (Y), in lower positioning seat, be coaxially connected with a locating dowel (4b) by radial block (4a), this locating dowel upper end is up-small and down-big conus portion; Described lower positioning seat (4) end face coaxial support has one to press down sleeved (5), this presses down the external diameter that sleeved external diameter is greater than lower positioning seat (4), being coaxially connected with a positioning sleeve (5b) by radial column (5a) pressing down in sleeved (5), matches with the conus portion of described locating dowel (4b) upper end in the bottom of this positioning sleeve centre bore; Described press down sleeved (5) top be coaxially provided with one press down dress abutment sleeve (6), these two parts all for being set with external toothing (W), and press down sleeved (5) outside once can be set with 8-10 external toothing (W); Described press down dress abutment sleeve (6) height higher than pressing down sleeved (5), this press down dress abutment sleeve outer wall be big end down taper seat, the external diameter of its lower end is identical with the diameter pressing down sleeved (5); The described lower end pressing down dress abutment sleeve (6) centre bore is provided with a lower annular boss (6a), and this lower annular boss and the described inner hole wall pressing down sleeved (5) are fitted;
Described lower cover (7) opening down, and described in can being enclosed within, press down dress abutment sleeve (6) outside, and on described moving assembly effect under, to pressing down described external toothing (W), when the contact of lower cover (7) inner top surface presses down dress abutment sleeve (6) end face, press down on sleeved (5) described in just all external toothings (W) pressing down the upper suit of dress abutment sleeve (6) being pressed onto;
Step b: press down sleeved (5) that processed external toothing (W) first will be housed and be contained on lower positioning seat (4), then to load onto one above sleeved (5) and press down dress abutment sleeve (6) pressing down, and pressing down dress abutment sleeve (6) outside suit one group of unprocessed external toothing (W), the number of undressed external toothing (W) and specification are identical with processing external toothing (W); Secondly, pressing down dress abutment sleeve (6) outside suit lower cover (7), the lower surface of this lower cover (7) is pressed on undressed external toothing (W) end face in the top; The pressure head (YT) finally controlling described press (Y) moves down, thus will press down by lower cover (7) the undressed external toothing (W) filled on abutment sleeve (6) and be press fit into and press down on sleeved (5), and the external toothing of processing (W) pressed down on sleeved (5) is pressed onto lower positioning seat (4);
Step c: take off lower cover (7) successively, press down dress abutment sleeve (6) and press down sleeved (5), and gear hobbing process will be carried out with pressing down on sleeved (5) clamping to gear-hobbing machine of undressed external toothing (W), the external toothing of processing (W) on lower positioning seat (4) is then taken off by workman.
In the above-mentioned methods, upper moving assembly can only press pressure head drive under move up and down, and press down sleeved (5), press down dress abutment sleeve (6) and lower cover (7) be demountable.Pressing down what sleeved (5) were first set with is the external toothing (W) having rolled tooth, and to press down what dress abutment sleeve (6) was first set be the external toothing (W) of non-gear hobbing, and press down sleeved (5) and press down external toothing (W) number that fills abutment sleeve (6) and specification identical.When press-fiting, upper moving assembly depresses gland (7) downwards, and by press down the external toothing (W) sleeved (5) having rolled tooth be pressed onto press down sleeved (5) outside, the external toothing (W) pressing down non-gear hobbing on dress abutment sleeve (6) is then pressed onto and presses down on sleeved (5), sleeved (5) clamping will be pressed down on gear-hobbing machine with promising gear hobbing external toothing (W) so that follow-up, and then carry out gear hobbing operation.
After completing gear hobbing process, to install on lower positioning seat (4) with press down sleeved (5) of gear hobbing external toothing (W) again, then dress abutment sleeve (6) is pressed down pressing down to load onto above sleeved (5), secondly the gear hobbing external toothing (W) being set with one group of non-gear hobbing outside dress abutment sleeve (6) is being pressed down, finally pressing down dress abutment sleeve (6) top suit lower cover (7), thus will press down by lower cover (7) the gear hobbing external toothing (W) filling non-gear hobbing on abutment sleeve (6) and be press fit into and press down on sleeved (5), and the external toothing of gear hobbing (W) that will press down sleeved (5) is pressed onto on lower positioning seat (4) simultaneously, manually to take off the external toothing (W) of gear hobbing, and cycling and so forth.
Adopt above technical scheme, the present invention can by the external toothing processed from pressing down sleeved taking off, and the external toothing of non-gear hobbing is press fit into simultaneously press down sleeved on, sleeved clamping will be pressed down to gear-hobbing machine upper rolling tooth with non-gear hobbing external toothing in subsequent handling, and press down sleeved on can press-fit 8-10 external toothing, so just can significantly improve gear hobbing efficiency, thus the defect that the working (machining) efficiency of customer service prior art is well low, and this pressing method adopt the structure of press-fitting tool simple, easy to use, easy to implement.
In the present case, described lower positioning seat (4) is welded and fixed by radial block (4a) and locating dowel (4b).
For the ease of connecting, described upper horizontal pressure foot (1) is fixed by the pressure head (YT) of bolt and press (Y).
Beneficial effect: the present invention can by the external toothing processed from pressing down sleeved taking off, and the external toothing of non-gear hobbing is press fit into simultaneously press down sleeved on, sleeved clamping will be pressed down to gear-hobbing machine upper rolling tooth with non-gear hobbing external toothing in subsequent handling, and press down sleeved on can press-fit 8-10 external toothing, so just can significantly improve gear hobbing efficiency, thus the defect that the working (machining) efficiency of customer service prior art is well low, and this pressing method adopt the structure of press-fitting tool simple, easy to use, easy to implement.
Accompanying drawing explanation
