Description

A kind of machine for setting multi-rod screw
Technical field
The present invention relates to a kind of multiaxis rotary tool, specifically is a kind of machine for setting multi-rod screw.
Background technology
Spiral marking connection is one of most common form of combination between the element part, have the precision height, convenient for assembly, be easy to safeguard, the standardization level advantages of higher, so be one of most economical, most widely used manufacturing means in the modern machines manufacturing.But the inefficacy of spiral marking connection also is machine one of the property sent out fault often, so connecting the research of mechanism, failure cause, the equal double thread in countries in the world pays close attention, constantly develop screw thread on this basis and tighten technology and control method, the microelectric technique of application of advanced and computer technology have produced numerical control bolt screwing machine of new generation.
The bolt screwing machine tool of using in the industrial production still for pneumatic, is electronic secondly mostly at present, and minority is a fro hydraulic driving machinery.Along with microelectric technique and development of computer over nearly two, 30 years, electronic bolt screwing machine and numerical control screwing machine also arise at the historic moment, and progressively move to maturity.Because electric tool control is convenient, noise is little, Torque Control precision height, advantage such as easy to adjust and be subjected to people's favor gradually, and has become fresh combatants in the tightening tool.Single shaft electric tightening machinery is popularized in production assembling and various maintenance department.Comparatively speaking, the technical difficulty of the electronic screwing machine of development multiaxis is bigger, has only a few countries to develop this type of machine at present in the world, and is applied in the assembly process of industries such as automobile, light industry, compressor.All developed electronic machine for setting multi-rod screw, and in automobile industry, be applied as U.S.'s Ingersoll-rand (Ingersoll-Rand) company, German DGD company, Sweden Atlas Copco assembly automation Co., Ltd.But the machine for setting multi-rod screw of above-mentioned use can only be used on a kind of same model spiral shell rifle of position distribution and use, for different model or/and the different many groups bolt in spiral shell rifle position can not carry out operation simultaneously.U.S. Pat 4542576 discloses a kind ofly rotates the tightening machine that changes distribution diameter around a fixed axis respectively by tappet head, the elastic tappet head that is proposed can change the bolt quantity that can tighten, it doesn't matter with the circle distribution that changes tappet head, sees it is to realize two kinds with one group of tappet head radially to switch effect on the whole; Because of the mechanism principle that is subjected to rotate around a fixed axis respectively limits, its tappet head distribution diameter has only conversion within the specific limits, promptly can only be tightened in the bolt in certain distribution diameter scope, be distributed in the distribution angle relative fixed of the bolt on the different circumference, promptly tighten the distribution relation of mechanism and flexible device and fix, elastic tappet head can not change distribution.
Chinese patent (patent No. ZL97115734.0) discloses a kind of machine for setting multi-rod screw, be that two groups of many wrench shafts are set on the pedestal of tightening machine, and on one group of multiaxis wrench shaft, set up a switching device shifter, change the length that wrench shaft stretches out by the operation switching device shifter, make two groups of many wrench shafts carry out operation respectively, can tighten operation the bolt of two kinds of differences (or identical) type and/or the bolt of different distributions.Though this have the bolt screwing machine operation simultaneously of handoff functionality in the different model bolt, solved a tractor serves several purposes problem, improved efficiency of assembling, but owing to structurally be that per two different circumference tappet heads are equipped with a motor, a reductor, a torque sensor, structure more complicated; The reference diameter of tappet head is fixed in addition, thereby makes its application be subjected to certain restriction.
Summary of the invention
In order to overcome above-mentioned deficiency, a kind ofly drive and ` becomes the machine for setting multi-rod screw of tappet head distributing position by power set but the purpose of this invention is to provide.
To achieve these goals, technical scheme of the present invention is: have a plurality of bolt tappet heads, motor, also comprise gear wheel, support, pinion, clutch, synchronous pulley mechanism, connecting rod slider mechanism, angular transducer, brake coupling, gyroaxis, star pawl, support disk, wherein: support is installed together by pinion shaft and support disk, on the described pinion shaft pinion is arranged, tighten motor and be installed in the support center, link to each other described gear wheel and each pinion with gear wheel by being used to drive the main shaft of tightening that tappet head rotates; Reference circle is adjusted motor and is installed on the support disk, link to each other with star-like pawl by gyroaxis, installation one is used to lock the brake coupling of star-like pawl on the gyroaxis, installing connecting rods slide block mechanism and one overlaps synchronous pulley mechanism respectively on described each pinion shaft, the end of connecting rod slider mechanism and synchronous pulley mechanism is the bolt tappet head, one clutch that is used to lock pinion and synchronous pulley mechanism also is installed on the axle of each pinion, and reference circle is adjusted on the motor and also is provided with angular transducer;
Described gyroaxis with tighten spindle axis and overlap; Described connecting rod slider mechanism is made up of connecting rod, slide block, and two connecting rods are installed between the arm of each pinion shaft and bolt tappet head, and synchronous pulley mechanism is between two connecting rods, and the slide block on connecting rod is fixed on the end of star pawl; Described bolt tappet head quantity equates that with the pinion shaft number pawl number of star-like pawl is corresponding with the number of bolt tappet head, can be at least 2.
Compared with prior art, the present invention has following beneficial effect:
1. simple in structure, easy to use.Because bolt screwing machine of the present invention is driven by power set, and a motor that is used to tighten is promptly only arranged, structure is simple relatively, easily processing; And it is output as a plurality of axles of tightening capable of being combined that are distributed on the circumference, can form 2,3,4,5 or 6 or more, has increased the flexibility of operation, multiple functions such as the present invention just has in addition changes, counter-rotating, moment, speed adjusting.
2. applicability is strong.The present invention adopts connecting rod slider mechanism, installing connecting rods slide block mechanism and one overlaps synchronous pulley mechanism respectively on the axle of described each pinion 5, the end of connecting rod slider mechanism and synchronous pulley mechanism is the bolt tappet head, this structure is compared with tightening machine in the prior art, make the present invention can change the distributing position of tappet head, the reference diameter that is its tappet head can be regulated and set, and regulate and in allowed band, to change continuously, so the present invention has wide range of applications, tighten as the bolt that can apply to different tonnage wheels.Because end-of-arm tooling of the present invention is replaceable, when loading onto screw tap or drill bit at output, also can be used for carrying out operations such as tapping or boring.
