Description
Technical field
The invention belongs to panoramic table driver, be applied to that somerset turns to or logistics transmission process in the panoramic table carried of object break-in.
Background technology
The panoramic table using on production line relies on motor to drive, and engages through the gear of reducing gear and the gear of gyro black assembly, completes the rotation of panoramic table, and this class formation is only applicable to the revolution of small article; For turning to of for example automobile of large-sized object, referring to Chinese patent literature CN201991281U in disclosed one on September 28 " automobile revolving platform driver " in 2011, it comprises automobile revolving platform and panoramic table driver installing plate, mounted motor driven unit on installing plate, drive friction pulley assembly and tensioning wheel assembly, drive friction pulley assembly to be connected with automobile revolving platform.Automobile revolving platform driver is provided with a pretension assembly, and the side that described pretension assembly is arranged at installing plate is connected with installing plate.Its operating principle is: electric machine main shaft rotates by chain and is delivered to and drives friction pulley assembly, driving automobile panoramic table under frictional force effect, and tensioning wheel assembly ensures chain tension, pretension assembly regulates and tensioning installing plate, to provide friction needed pressure.
As can be seen here, existing panoramic table driver is all the gyration that rotatablely moving of driving mechanism is transformed to panoramic table.At present, also the back and forth movement of driving mechanism is not transformed to the relevant record of the gyration of panoramic table.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of panoramic table driver, and the back and forth movement that it can provide driving mechanism is transformed to the gyration of panoramic table, and angle of revolution reaches 180o.
Technical problem to be solved by this invention is to realize by such technical scheme, it includes pusher, first connecting rod and second connecting rod, one end of first connecting rod is hinged in frame with the first bearing pin, first connecting rod swings around the first bearing pin, the middle part of first connecting rod is hinged with the second bearing pin and pusher push rod termination, the free end of first connecting rod is equipped with the 3rd bearing pin, the 3rd bearing pin is plugged in the chute of second connecting rod and slides along chute, one end of second connecting rod is fixedly connected on the rotating column of energy, the other end of second connecting rod is free end, within column is positioned at the free end swing camber line of first connecting rod.
In the time that pusher push rod stretches out, promote first connecting rod and swing around the first bearing pin, the free end of first connecting rod is done movement in a curve, and the 3rd bearing pin of movement in a curve is positioned at second connecting rod chute, promote second connecting rod and drive column to rotate, column drives the panoramic table revolution on top.In the time that first connecting rod swings maximum angle β, second connecting rod drives column and panoramic table to rotate 180o, and in the time of pusher pusher retracted, panoramic table resets.
So technique effect of the present invention is: the back and forth movement that driving mechanism can be provided is transformed to the gyration of panoramic table, and angle of revolution reaches 180o, be specially adapted to the occasion of fluid pressure actuated.
Brief description of the drawings
Brief description of the drawings of the present invention is as follows:
Fig. 1 is structural representation of the present invention;
Fig. 2 is Plane Rotation schematic diagram of the present invention.
In figure: 1. pusher; 2. first connecting rod; 3. second connecting rod; 4. the first bearing pin; 5. the second bearing pin; 6. the 3rd bearing pin; 7. rolling bearing; 8. column; 9. frame; 10. panoramic table.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As depicted in figs. 1 and 2, the present invention includes pusher 1, first connecting rod 2 and second connecting rod 3, one end of first connecting rod 2 is hinged in frame 9 with the first bearing pin 4, first connecting rod 2 swings around the first bearing pin 4, the middle part of first connecting rod 2 is hinged with pusher 1 push rod termination with the second bearing pin 5, the free end of first connecting rod 2 is equipped with the 3rd bearing pin 6, the 3rd bearing pin 6 is plugged in the chute of second connecting rod 3 and slides along chute, one end of second connecting rod 3 is fixedly connected on the rotating column 8 of energy, the other end of second connecting rod 3 is free end, within column 8 is positioned at the free end swing camber line of first connecting rod 2.
The course of work of the present invention as shown in Figure 2, in the time that pusher 1 push rod stretches out, promoting first connecting rod 2 swings around the first bearing pin 4, the free end of first connecting rod 2 is done movement in a curve, the 3rd bearing pin 6 of movement in a curve is positioned at second connecting rod 3 chutes, promote second connecting rod 3 and drive column 6 to rotate, column 6 drives the panoramic table 10 on top to turn round.In the time that first connecting rod 2 swings maximum angle β, second connecting rod 3 drives column and panoramic table to rotate 180o, and in the time of pusher 1 pusher retracted, panoramic table resets.Can control panoramic table by the swing position of first connecting rod 2 and rest on unspecified angle within the scope of 0 ~ 180o.
Found out by Fig. 2, in the time that first connecting rod 2 length are determined, first connecting rod 2 full swing angle betas are the distance dependent with column 8 with the first bearing pin 4.When column 8 swings the top of camber lines the closer to first connecting rod 2 free ends, it is less that second connecting rod 3 turns round the first connecting rod 2 full swing angle betas that 180o is corresponding; Otherwise when column 8 is the closer to the first bearing pin 4, first connecting rod 2 full swing angle betas are larger.
Because pusher 1 push rod termination is hinged on the middle part of first connecting rod 2, in the time that promotion first connecting rod 2 swings around the first bearing pin 4, movement in a curve is also done with each location point on first connecting rod 2 in pusher 1 push rod termination, movement in a curve for fear of pusher 1 push rod termination causes vibration to pusher 1, offer a radial groove at first connecting rod 2 middle parts and pusher 1 hinged place, push rod termination, the second bearing pin 5 is through this radial groove, and the two ends of the second bearing pin 5 are fixed on the Y-piece both sides of pusher 1 push rod termination.Like this, pusher 1 push rod is made back and forth movement, and the second bearing pin 5 slides in the radial groove of first connecting rod 2, has overcome pusher 1 push rod termination radial motion and cause the vibration of pusher 1.
Between the 3rd bearing pin 6 and second connecting rod 3 chutes, rolling bearing 7 is housed, the outer ring of rolling bearing 7 and second connecting rod 3 chutes are matched in clearance, rolling bearing 7 rolls in chute, sliding friction between the 3rd bearing pin and second connecting rod 3 chutes is become to the rolling friction between rolling bearing 7 and chute, reduce transmission resistance.Equally, between the second bearing pin 5 and first connecting rod 2 radial grooves, rolling bearing is housed, the outer ring of rolling bearing and first connecting rod 2 radial grooves are matched in clearance.
