Description
Technical field
The utility model relates to plant equipment field, is specifically related to a kind of anti-wrap device.
Background technology
Industrial robot is used widely in recent decades, and is applied to industry-by-industry.The assessment of all industries, industrial robot will be one of industrial equipment of following 20 years tool potentiality.Though industrial robot, through the development of four more than ten years, has passed through countless improvement and variation, but still there is many defects, as the cable of robot interior can't effectively prevent from being wound around and wearing and tearing in the time working.Traditional method is that steel wire sheath is wound around and wearing and tearing preventing in cable outer cover, but this method prevents the poor effect being wound around, once and steel wire sheath wearing and tearing, cable also can produce wearing and tearing very soon.
Utility model content
The purpose of this utility model provides robot anti-wrap device, solves one or more in above-mentioned prior art problem.
According to robot of the present utility model anti-wrap device, comprise rotary body, fixed body, hollow shaft and cable, rotary body is made up of wheel shaft and end cap, propping up that fixed body is fixedly connected with by harmonic speed reducer and with harmonic speed reducer is configured to, and wherein end cap one end is connected with wheel shaft, and the other end is connected with harmonic speed reducer by bearing one, hollow shaft is arranged in harmonic speed reducer, one end is connected by bearing two with end cap, and the other end is connected by bearing three with support, and cable passes in hollow shaft.
Because cable is contained in hollow shaft, and bearing has been installed at hollow shaft two ends, make hollow shaft energy and cable synchronous rotary, so just can prevent the possibility that cable is wound around at work, when cable rotation, also can in hollow shaft, not rub with contact component, extend the service life of cable.
In some embodiments, end cap is connected with wheel shaft plug-in type, and fixes with bolt.Simple in structure, be easy to install, dismantle and maintenance.
In some embodiments, harmonic speed reducer is fixedly connected with by soket head cap screw with support.Such connected mode can ensure the installation accuracy of harmonic speed reducer and support, can ensure again the structural strength that both connect.
In some embodiments, bearing one is crossed roller bearing.Owing to connecting by crossed roller bearing between end cap and harmonic speed reducer, facilitate like this staff to install and operation, and made the running accuracy between bearing one and harmonic speed reducer higher, and be difficult for producing wearing and tearing.
In some embodiments, one end that wheel shaft is not connected with end cap connects servomotor.Servomotor can be controlled the speed of rotary body fast, and positional precision is high, improves robot work precision.
In some embodiments, bearing two is provided with the locking nut matching with it, between locking nut and bearing two, packing ring is also installed.Can effectively reduce like this scratch of locking nut and bearing two, extend both service life.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment assembled state of the present utility model;
Fig. 2 is the schematic diagram of the decomposing state of another kind of embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in more detail.
As Fig. 1, shown in Fig. 2, robot anti-wrap device, comprises rotary body 1, fixed body 2, hollow shaft 3 and cable 4, and rotary body 1 is made up of wheel shaft 11 and end cap 12, fixed body 2 is made up of harmonic speed reducer 21 and support 22, harmonic speed reducer 21 and support 22 are fixing by soket head cap screw 8, and wherein insert in wheel shaft 11 end cap 12 one end, and be bolted, bolt is arranged on end cap 12, and wheel shaft 11 is provided with the bolt hole corresponding with bolt.Wheel shaft 11 is not connected with servomotor with one end that end cap 12 is connected, and servomotor can be controlled the speed of wheel shaft 11 fast, and positional precision is high, and such structural design makes the operating accuracy of robot high.One end that end cap 12 is not connected with wheel shaft 11 is connected with harmonic speed reducer 21 by bearing 1, bearing 1 is selected crossed roller bearing, straight oil nozzle is also installed on crossed roller bearing, conveniently do lubricated to crossed roller bearing, so not only facilitate staff's installation and operation, and make crossed roller bearing and and harmonic speed reducer 21 between running accuracy higher, can also reduce at machine man-hour the wearing and tearing of end cap 12 and harmonic speed reducer 21.
Hollow shaft 3 is arranged in harmonic speed reducer 21, one end is connected by bearing 26 with end cap 12, bearing 26 is provided with the locking nut 9 matching with it, between locking nut 9 and bearing 26, packing ring 10 is also installed, can effectively reduce like this scratch of locking nut 8 and bearing 1, extend both service life.Hollow shaft 3 other ends are connected by bearing 37 with support 22, and cable 4 passes in hollow shaft 3, are connected with servomotor.Because cable 4 is contained in hollow shaft 3, and hollow shaft 3 two ends have installed bearing, make hollow shaft 3 can and cable 4 synchronous rotaries, so just can prevent the possibility that cable 4 is wound around at work; When cable 4 rotates, also can in hollow shaft 3, not rub with contact component, so just can prevent muchly that cable 4 from being worn and torn at work.Effectively extend the service life of cable 4.
Industrial machine man-hour, servomotor is opened, and rotary body 1 rotates, and because the end cap 12 in rotary body 1 is connected by bearing 1 with harmonic speed reducer 21, therefore, by the rotating speed of the adjustable wheel shaft 11 of harmonic speed reducer 21, makes industrial robot work accurate.In this process, cable 4 passes in hollow shaft 3, do not contact with end cap 12, and by bearing 26 and bearing 37 and hollow shaft 3 synchronous rotaries.
The above is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some similar distortion and improvement, within these also should be considered as protection domain of the present utility model.
