Summary of the invention
For overcoming at present in the technical problem eliminating operating difficulties existing in multipoint mode eccentric gear of press machine phase difference process, waste time and energy, the invention provides a kind of press gear transmission device with eccentric corner adjusting offset function.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: the press gear transmission device with eccentric corner adjusting offset function, it comprises the eccentricity gear of each point position, eccentricity gear engages with the main pinion of this some position, main pinion live axle is provided with intermediate gear, intermediate gear engages with high speed pinion gear, it is characterized in that: one of them intermediate gear adopts gear ring and wheel hub that conjunction mode is formed, described wheel hub is fixed on main pinion live axle, wheel hub is positioned at gear ring inner, ring-type disc bonded to each other is respectively equipped with in the outer rim of wheel hub and gear ring inner edge, by fixing closing screw between two ring-type disc, be provided with one to cave in groove at wheel hub edge, the gear ring body corresponding with the groove that caves in is provided with location counterbore, cave in groove and be provided with a rectangle adjustment saddle, adjustment saddle is provided with locating stud, locating stud is inserted in the counterbore of location, screwed through hole is provided with in adjustment saddle inside, the two ends of through hole are respectively equipped with adjustment screw, the afterbody of adjustment screw is against and caves on the cell wall of groove,
When carrying out adjusting offset, after unclamping the conjunction screw on two ring-type disc, wheel hub can be made to produce rotation at gear ring inner by rotating adjustment screw;
After adjusting offset, two ring-type disc process some through pin-and-holes, in pin-and-hole, be provided with the conjunction of pin for two disc.
Because the difference of phase difference is generally little, the elimination that slight adjustment can realize phase difference only need be carried out during adjustment, adopt adjusting offset transmission system provided by the invention can carry out the fine setting of phase difference easily, all gear train assemblies are loaded in cross girder, after detecting phase difference value, wheel hub only need be made to produce fine rotation, drive eccentricity gear to go to assigned position and namely complete adjustment work, it is easy to adjust, quick, the adjustment work of phase difference can be met fast, significantly reduce adjustment intensity, ensure that the operating accuracy of press ram.

Embodiment
Be described further for the transmission gear means of kinds of point mode press machine below, the description see kinds of point mode structure can learn the adjustment of 4 point type press machine phase differences easily.
The drive mechanism of kinds of point mode press machine left and right sides eccentricity gear describes see existing in the introduction shown in accompanying drawing 1 and accompanying drawing 2, does not repeat them here.
As shown in Figure 1, in the gear train assembly of kinds of point mode press machine, the right intermediate gear 2-2 in the gear train assembly of right side eccentricity gear 1-2 is improved, shown in the structural member accompanying drawing 3 of right intermediate gear 2-2, accompanying drawing 4 and accompanying drawing 5.It adopts gear ring 6 and wheel hub 7 that conjunction mode is formed.As shown in Figure 4, described wheel hub 7 is fixed on right main pinion live axle 3-2-1, and it is inner that wheel hub 7 is positioned at gear ring 6, is respectively equipped with between ring-type disc 8, two ring-type disc bonded to each other by fixing closing a screw 9 in the outer rim of wheel hub and gear ring inner edge.
As shown in accompanying drawing 3 and accompanying drawing 5, be provided with one to cave in groove 10 at wheel hub 7 edge, the gear ring body corresponding with the groove that caves in is provided with and locates counterbore 11, cave in groove and be provided with a rectangle adjustment saddle 12, adjustment saddle is provided with locating stud 12-1, and locating stud 12-1 is inserted in the counterbore 11 of location, is provided with screwed through hole in adjustment saddle inside, the two ends of through hole are respectively equipped with adjustment screw 13, and the afterbody of adjustment screw is against and caves on the cell wall of groove.
By reference to the accompanying drawings 3 and accompanying drawing 1 shown in, when carrying out adjusting offset, the handle first unscrewed between wheel hub 7 and gear ring 6 closes screw 9, then turns the adjustment screw 13 of adjustment saddle 12 side, make it to depart from wheel hub 7, and then the adjustment screw turning opposite side makes wheel hub 7 and gear ring 6 relatively rotate.Now in gear train assembly, owing to engaging with left intermediate gear 2-1 with gear ring 6, and left intermediate gear 2-1 also engages with high speed level small gear 4, so the resisting moment of rotating wheel hub 7 is less than the resisting moment of rotating gear ring 6, so gear ring does not rotate, and hub rotation, the wheel hub rotated drives right avertence heart pinion rotation by right main pinion live axle 3-2-1, when the eccentric corner adjusting offsets of two eccentricity gears are to after making slide block reach desired kinematic accuracy, that turning that elder generation and wheel hub depart from adjusts screw, make it and hub contacts, tighten closing screw 9 again, and with spot welding method, wheel hub and gear ring are fixed.Now split out by the gear ring wheel hub fixed from gear shaft, upper lathe is pin hole processing simultaneously, loads pin 14, and by after spot-welded together to pin 14 and wheel hub, reinstalls on gear shaft.The structure installing the right intermediate gear 2-2 of pin 14 is shown in shown in accompanying drawing 3 and accompanying drawing 4, installs pin 14 additional and can make to transmit larger moment of torsion between wheel hub and gear ring.Owing to regulating on intermediate gear shaft, and finely tune with adjustment screw, therefore adjust comparatively easy and accurate.
According to foregoing description, as long as carry out improvement to the structure of one of them intermediate gear of the left and right sides according to foregoing description can carry out adjusting offset easily in kinds of point mode press machine system.In like manner, in 4 point type press machine systems, the adjustment of phase difference can also be realized.
