Description
Technical Field
The invention belongs to the technical field of jacking positioning mechanisms, and relates to a floating jacking positioning mechanism of an elevator.
Background
The marine polyurethane insulation case of LNG, its box is formed by plywood and cystosepiment through the mode veneer of industry glue, because its overall dimension requires strictly, must retrain it with the tensioner after the veneer is accomplished, prevents to lead to the dislocation between plywood and the cystosepiment because of the shake in the transportation or other reasons.
The automatic sleeving of the tensioner is a key for solving the problem of the whole gluing production line, and in the processing process of the existing production line, the tensioner is firstly sleeved into a tensioner tray manually, and then the sleeving and the disassembling of the tensioner are realized through logistics and a robot. The positioning of the pallet becomes one of the difficulties of the whole gluing line, and the traditional solution adopts a sensor positioning mode which has the following problems:
1. under the positioning condition of the traditional positioning mode, a certain delay condition exists between a sensor and a processing signal, and the speed nonuniformity of a servo in the stopping process of the sensor causes a certain deviation between the stopping position and the ideal position in the actual operation process, so that the positioning precision can not meet the requirement only by positioning the sensor.
2. In a traditional positioning mode, after a sensor stops, the sensor is guided to enter the sleeving and disassembling action in a positioning pin mode, and due to the fact that positioning accuracy is insufficient, vibration is easy to occur in the positioning process, and the tensioner can be caused to shift on the tray; especially when the deviation is great, or can not advance the locating pin at all, lead to the automatic in-process of snatching must the personnel participate in can normally move, greatly reduced assembly efficiency.
3. Traditional locate mode, because positioning accuracy does not enough lead to needing artifical the participation, on the one hand because personnel get into automatic production line and be unfavorable for workman safety protection, on the other hand, artifical the participation solution also reduced production efficiency simultaneously after the location problem appears, produces very big influence to the productivity of whole line.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a floating jacking positioning mechanism of an elevator.
The purpose of the invention can be realized by the following technical scheme:
an elevator floating jacking positioning mechanism comprising:
fixing a plate: is arranged on a ground foundation;
a dowel assembly provided on the fixed plate: the device comprises a plurality of groups of positioning pin units for accurately positioning workpieces;
the setting is on the fixed plate and is located two sets of ball assembly floats of locating pin subassembly both sides: the device comprises a supporting piece fixed on a fixing plate, a jacking unit arranged on the supporting piece and capable of moving up and down along the vertical direction, a floating ball mounting plate arranged at the top end of the jacking unit, and at least one floating ball unit arranged on the upper surface of the floating ball mounting plate.
Furthermore, the positioning pin unit comprises a height adjusting rod arranged on the fixing plate and a taper sleeve arranged at the top end of the height adjusting rod.
Furthermore, the taper sleeve is of a tapered structure with an upper tip and a lower thick, and the taper is 1: 1.5 to 2.2.
Furthermore, the size of the height adjusting rod and the taper sleeve satisfies the following requirements: when the jacking unit rises to the highest position, the height of the floating ball unit is lower than that of the top end of the taper sleeve; when the jacking unit descends to the lowest position, the height of the floating ball unit is lower than that of the bottommost end of the taper sleeve.
Furthermore, the lower surface of the taper sleeve is connected with the height adjusting rod through a plurality of locking screws, the number of the locking screws is preferably four, and the flatness of the taper sleeve can be finely adjusted by adjusting the locking screws.
Furthermore, the jacking unit comprises a jacking cylinder arranged on the supporting piece, and the output end of the jacking cylinder is also connected with the floating ball mounting plate and drives the floating ball mounting plate to move up and down along the vertical direction.
Furthermore, a guide hole which is communicated along the vertical direction is further processed on the supporting piece, a guide rod which slides up and down along the guide hole is arranged in the guide hole, and the upper end of the guide rod is fixedly connected with the floating ball mounting plate. The guide bar is preferably distributed on two sides of the jacking cylinder and symmetrically distributed, so that the effect that the cylinder is subjected to radial force is reduced, and the guide effect is achieved.
Furthermore, the floating ball unit comprises a ball cage arranged on the floating ball mounting plate and a positioning floating ball which is rotatably arranged on the ball cage and the upper part of which is exposed.
Furthermore, a damping piece which is contacted with the surface of the positioning floating ball is arranged on the ball cage.

After the full tray is in place, the elevator obtains a descending instruction, the elevator waits for the ascending of the floating jacking positioning mechanism to be in place, the cylinder of the floating ball mechanism sends an in-place signal after ascending in place (at the moment, the positioning surface of the floating ball unit is 10mm-15mm lower than the positioning surface of the positioning pin unit, the main purpose is to prevent the tray from generating uncontrolled movement on the floating ball mechanism due to the fact that all floating balls are not on the same horizontal plane caused by the installation precision problem), at the moment, the elevator starts to descend, the elevator decelerates to the lowest position when approaching the floating ball mechanism and sends an in-place signal, the floating ball mechanism starts to descend after obtaining the in-place signal of the elevator, the cylinders on the two sides send action completion signals after descending in place. After the tensioners on the tray are used up, the elevator rises to the position of the logistics raceway at the lower layer, the tray of the empty tensioner is conveyed away through logistics, after the action is finished, the elevator continues to rise to the position of the full tray at the upper layer, and then the process is repeated.
Compared with the prior art, the invention has the following advantages:
(1) the floating ball unit is favorable for improving the stability when the positioning error is adjusted greatly, reduces violent shaking caused by dislocation, improves the positioning precision, prolongs the service life of the positioning device and improves the economic benefit.
