For the bascule of manipulator welding rotary table
Technical field
The utility model relates to field of machining, particularly a kind of servicing unit when welding.
Background technology
In manipulator welding processing process, workpiece to be welded is placed on rotary table, overturns workbench to complete weld job by corresponding power set.Due to the weight of workpiece to be welded and the weight of rotary table self, the two ends weight causing rotary table to rotate about the axis is inconsistent, rotary table can produce torsion because two ends weight is inconsistent when overturning, great load is brought to the upset power set of rotary table, not only affect the reversal rate of workbench, also affect the service life of equipment, the welding quality of workpiece also can be caused simultaneously unstable, reduce operating efficiency.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, low cost of manufacture, the easy to use and bascule of the manipulator that adjustable range is larger welding rotary table, to solve above-mentioned problems of the prior art.
The technical scheme that the utility model adopts for achieving the above object is: a kind of bascule for manipulator welding rotary table, described bascule comprises two pieces of balancing weight support bars and is separately positioned on the balancing weight on balancing weight support bar, described balancing weight support bar is symmetricly set on rotary table two ends respectively, each block balancing weight support bar is provided with multiple gravity adjustment hole, and balancing weight can be positioned in any one the gravity adjustment hole on balancing weight support bar.
Further technical scheme of the present utility model is: described every block balancing weight support bar is provided with five gravity adjustment holes.
Of the present utility model more further technical scheme be: described balancing weight support bar is connected to rotary table two ends by the turnover disc be connected with rotary table two ends respectively, balancing weight support bar by alignment pin and Bolt to position on turnover disc.
The bascule that the utility model is used for manipulator welding rotary table has following beneficial effect: the weight balancing at two ends when the utility model can regulate rotary table to overturn, the torsion produced because two ends weight is inconsistent when reducing upset, the reversal rate of workbench can be increased, the service life of extension device, the welding quality of workpiece can also be ensured simultaneously, increase work efficiency.In addition, balancing weight support bar is provided with multiple gravity adjustment hole, can, according to the weight of workpiece, balancing weight is arranged on corresponding gravity adjustment hole, to reach the object of adjustment.
Below in conjunction with drawings and Examples, the bascule that the utility model is used for manipulator welding rotary table is further described.

Drawing reference numeral illustrates: 1-balancing weight, 2-balancing weight support bar, 3-gravity adjustment hole, 4-turnover disc, 5-rotary table, 6-bolt, 7-alignment pin.
Detailed description of the invention
As shown in Figure 1, a kind of bascule for manipulator welding rotary table, the balancing weight 1 that described bascule comprises two pieces of balancing weight support bars 2 and is separately positioned on balancing weight support bar 2, balancing weight support bar 2 is connected to rotary table two ends by the turnover disc 4 be connected with rotary table two ends respectively, balancing weight support bar 2 is positioned on turnover disc 4 by alignment pin 7 and bolt 6, each block balancing weight support bar 2 is provided with multiple gravity adjustment hole 3, in the present embodiment, every block balancing weight support bar 2 is provided with five gravity adjustment holes, each gravity adjustment hole weight differs 20 kilograms, minimum gravity adjustment hole is 50 kilograms, balancing weight 1 according to the weight of soldering set, can be fixed in any one the gravity adjustment hole 3 on balancing weight support bar 2.
When weld job, workpiece is placed on rotary table 5, and turnover disc 4 is connected with tipping arrangement.When workpiece needs the certain angle of upset to weld, tipping arrangement is together overturn by turnover disc 4 driven rotary workbench 5 and workpiece, under the effect of balancing weight 1, the weight at the two ends that rotary table rotates about the axis keeps balance, tipping arrangement can driven rotary working platform overturning very easily, completes weld job.
The weight of balancing weight can be determined according to the weight of soldering set, can also be regulated the stress equalization of overturn platform, thus reach the object of balance by the lifting in weight hole.
Above embodiment is only preferred embodiment of the present utility model; structure of the present utility model is not limited to the form that above-described embodiment is enumerated; all any amendments, equivalent replacement etc. done within spirit of the present utility model and principle, all should be included within protection domain of the present utility model.
