Description

A kind of panoramic table driver
Technical field
The invention belongs to panoramic table driver, be applied to the panoramic table that somerset turns to or in logistics transmission process, object break-in is carried.
Background technology
The panoramic table that production line uses relies on motor to drive, and through the gear of reducing gear and the gears meshing of gyro black assembly, complete the rotation of panoramic table, this class formation is only applicable to the revolution of small article; For turning to of large-sized object such as automobile, see Chinese patent literature CN201991281U a kind of " automobile revolving platform driver " disclosed in 28 days September 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 through chain and is delivered to driving friction pulley assembly, driving automobile panoramic table under frictional force effect, and tensioning wheel assembly ensures chain tension, and pretension assembly regulates and tensioning installing plate, to provide the pressure required for friction.
As can be seen here, existing panoramic table driver is all the gyration rotary motion of driving mechanism being 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 driving mechanism provides can be transformed to the gyration of panoramic table by it, and angle of revolution reaches 180 °.
Technical problem to be solved by this invention is realized by such technical scheme, it includes pusher, first connecting rod and second connecting rod, one end of first connecting rod by the first hinge in frame, first connecting rod swings around the first bearing pin, the middle part of first connecting rod with the second bearing pin and pusher push rod termination hinged, the free end of first connecting rod is equipped with the 3rd bearing pin, 3rd bearing pin to be plugged in the chute of second connecting rod and along slide, one end of second connecting rod is fixedly connected on the pivotal column of energy, the other end of second connecting rod is free end, the free end that column is positioned at first connecting rod swings within camber line.
When pusher push rod stretches out, promote first connecting rod to swing around the first bearing pin, the free end of first connecting rod does movement in a curve, and the 3rd bearing pin of movement in a curve is positioned at second connecting rod chute, promoting second connecting rod drives column to rotate, and column drives the panoramic table revolution on top.When first connecting rod swings maximum angle β, second connecting rod drives column and panoramic table to rotate 180 °, and when pusher pusher retracted, panoramic table resets.
So technique effect of the present invention is: the gyration that the back and forth movement that driving mechanism provides can be transformed to panoramic table, angle of revolution reaches 180 °, is specially adapted to the occasion of fluid pressure actuated.
Accompanying drawing explanation
Accompanying drawing of the present invention is described 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, 3rd bearing pin 6 to be plugged in the chute of second connecting rod 3 and along slide, one end of second connecting rod 3 is fixedly connected on the pivotal column 8 of energy, the other end of second connecting rod 3 is free end, the free end that column 8 is positioned at first connecting rod 2 swings within camber line.
The course of work of the present invention as shown in Figure 2, when pusher 1 push rod stretches out, promote first connecting rod 2 to swing around the first bearing pin 4, the free end of first connecting rod 2 does movement in a curve, 3rd bearing pin 6 of movement in a curve is positioned at second connecting rod 3 chute, promoting second connecting rod 3 drives column 8 to rotate, and column 8 drives the panoramic table 10 on top to turn round.When first connecting rod 2 swings maximum angle β, second connecting rod 3 drives column and panoramic table to rotate 180 °, and when pusher 1 pusher retracted, panoramic table resets.Panoramic table can be controlled by the swing position of first connecting rod 2 and rest on unspecified angle within the scope of 0 ~ 180 °.
Found out by Fig. 2, when first connecting rod 2 length is determined, first connecting rod 2 full swing angle beta is with the distance dependent of the first bearing pin 4 with column 8.When column 8 swings the top of camber line the closer to first connecting rod 2 free end, it is less that second connecting rod 3 turns round 180 ° of corresponding first connecting rod 2 full swing angle betas; Otherwise when column 8 is the closer to the first bearing pin 4, first connecting rod 2 full swing angle beta is larger.
Because pusher 1 push rod termination is hinged on the middle part of first connecting rod 2, when promoting first connecting rod 2 and swinging around the first bearing pin 4, movement in a curve is also done with each position point on first connecting rod 2 in pusher 1 push rod termination, in order to avoid the movement in a curve of pusher 1 push rod termination causes vibration to pusher 1, a radial groove is offered with hinged place, pusher 1 push rod termination in the middle part of first connecting rod 2, 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 makes back and forth movement, and the second bearing pin 5 slides in the radial groove of first connecting rod 2, overcomes the vibration that the termination radial motion of pusher 1 push rod causes pusher 1.
Between 3rd bearing pin 6 and second connecting rod 3 chute, rolling bearing 7 is housed, outer ring and second connecting rod 3 chute of rolling bearing 7 are matched in clearance, rolling bearing 7 rolls in chute, sliding friction between 3rd bearing pin and second connecting rod 3 chute is become the rolling friction between rolling bearing 7 and chute, reduces transmission resistance.Equally, between the second bearing pin 5 and first connecting rod 2 radial groove, rolling bearing is housed, outer ring and first connecting rod 2 radial groove of rolling bearing are matched in clearance.
