Description
Technical field
The invention belongs to jack detent mechanism technical field, it is related to a kind of elevator floating jacking positioning mechanism.
Background technique
LNG ship polyurethane insulating case, cabinet by glued board and cystosepiment by way of industrial glue it is glued and
At since its outer dimension requires strictly, it is necessary to be constrained with tension device it, be prevented due to transporting after the completion of gluing
Shake or other reasons in journey lead to the dislocation between glued board and cystosepiment.
The automation suit of tension device is the key that solve the problems, such as entire glue line, and existing production line is in process
In, tension device passes through first to be manually inserted in tension device pallet, subsequently through logistics and robot realize tension device suit and
Disassembly.The positioning of pallet becomes one of the difficult point of entire glue line, and what traditional solution was taken is sensor positioning
Mode, there are the following problems for which:
1. under traditional positioning method positioning scenarios, to processing signal, there are certain delay situations from signal is obtained for sensor
And wow and flutter of the servo in its stopped process leads to its stop position and ideal position in the actual operation process
There is certain deviation, so only positioning by sensors in place, positioning accuracy is not reached requirement.
2. traditional positioning method, after sensor stops again by positioning pin by way of carry out being directed into set installation and dismantling
Movement is unloaded, since positioning accuracy is inadequate, vibration is easy to appear in position fixing process, tension device is will lead to and is shifted on pallet；It is special
Be not when deviation is larger, or at all into not positioning pin, cause to have to during automatically grabbing people participates in could be normal
Movement, greatly reduces assembly efficiency.
3. traditional positioning method, since positioning accuracy not enough results in the need for manually participating in, on the one hand since personnel enter certainly
Dynamicization producing line is unfavorable for protecting safety of workers, on the other hand, manually participates in solving while also reducing after there is orientation problem
Production efficiency generates strong influence to the production capacity of sliver.
Summary of the invention
It is pushed up it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of elevator floats
Rise positioning mechanism.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of elevator floating jacking positioning mechanism, comprising:
Fixed plate: it is mounted in ground base；
Pin assembly in fixed plate is set: being used for the positioning pin unit of precise positioning workpiece including several groups；
It is arranged in fixed plate and is located at two groups of floating ball components of pin assembly two sides: including being fixed in fixed plate
Supporting element, is mounted on the floating of jacking unit top at the jacking unit that is arranged on supporting element and can move up and down along the vertical direction
Ball mounting plate, and it is arranged at least one floating ball unit of floating ball mounting plate upper surface.
Further, the positioning pin unit includes the height regulating rod being mounted in fixed plate and setting in height
The tapered sleeve on adjusting rod top.
Further, the tapered sleeve is pyramidal structure thick under upper point, and taper is 1:1.5~2.2.
Further, the size of height regulating rod and tapered sleeve meets: when jacking unit rises to extreme higher position, floating ball
The height of unit is lower than the height on tapered sleeve top；When jacking unit drops to extreme lower position, the height of floating ball unit is lower than cone
Cover the height of lowermost end.
Further, the lower surface of tapered sleeve is connect by multiple lock screws with height regulating rod, and lock screw is preferred
Using four, the flatness of tapered sleeve can be finely tuned by adjusting lock screw.
Further, the jacking unit includes the jacking cylinder being mounted on supporting element, the output of the jacking cylinder
End is also connected with the floating ball mounting plate, and floating ball mounting plate is driven to move up and down along the vertical direction.
Further, the pilot hole penetrated through along the vertical direction is also processed on supporting element, is equipped in the pilot hole along it
The guide rod slided up and down, the upper end of the guide rod are fixedly connected with the floating ball mounting plate.Guide rod is preferably distributed in jacking
Cylinder two sides, are symmetric, and on the one hand reduce cylinder by the effect of radial force, on the one hand play the guiding role.
Further, the floating ball unit include the cage being arranged on floating ball mounting plate, be rotatably arranged in cage and
The positioning floating ball that upper part is exposed.
Further, the damping piece contacted with the positioning floating ball surface is additionally provided in cage.In the present invention, damping
Part is the element for applying certain pivoting friction resistance after contacting with positioning floating ball surface to it.
Still more preferably, it is 0.4~0.6 that damping piece, which meets its coefficient of friction between positioning floating ball,.
In practical work process, elevator is in extreme lower position always, when tension device is in pallet-free shape using position
It (needs to see empty pallet off by lower layer's logistics when tension device is in empty pallet state using position, lower layer's logistics roller when state
Road face height need to be higher than positioning pin top 30mm or more), after elevator obtains climb command, elevator runs to upper layer and fills support
Disk position.Full tray in place after, elevator obtain decline instruction, elevator wait float jacking positioning mechanism rising in place,
After floating ball mechanism cylinder rises in place, issuing signal in place, (positioning surface of floating ball unit is lower than positioning pin cell location face at this time
10mm-15mm, main purpose be prevent from causing due to installation accuracy problem all floating balls not in same level so as to
Cause pallet that uncontrolled movement occurs in floating ball mechanism), elevator is begun to decline at this time, liter when close to floating ball mechanism
Drop machine runs slowly to extreme lower position and issues signal in place, and floating ball mechanism obtains elevator in place after signal, begins to decline dynamic
Make, signal is completed in sending movement after two sides cylinder is fallen into place, and system starts tension device and uses process.Tension device on pallet makes
After being finished, elevator rises to lower layer's logistics raceway position, and empty tension device pallet is seen off by logistics, after the completion of movement, rises
Drop machine continues to rise to upper layer and fills tray position, then repeats the above process.
Compared with prior art, the invention has the following advantages that
(1) being provided with for floating ball unit is conducive to improve the stability in position error larger adjustment, reduces due to dislocation
Caused by fierceness shake, improve positioning accuracy, increase the service life of positioning device, increase economic efficiency.
(2) floating positioning unit is used, is reduced since the positioning accuracy difference band of elevator carrys out system accuracy shakiness
It is qualitative, a possibility that reducing system jam, economic benefit is improved, strong support is provided for large-scale production.
(3) the superfluous of system is considerably increased using the location hole of large aperture low-angle and positioning pin unit matching on workpiece
Yu Xing reduces the influence being not allowed due to elevator chain structure positioning, reduces failure rate, improves production efficiency.
