Detailed description of the invention
Fig. 1 is a kind of bearing grease injection apparatus structure schematic diagram of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown, the utility model provides a kind of bearing grease injection device, including quantitative valve system, greasing jacking system
With SERVO CONTROL grease filling system three parts.Proportional valve cylinder 10, oil inlet 11, proportional valve 12 are specifically included, spiral shell is quantitatively adjusted
Bolt 13, greasing crane 20, oil transportation steel pipe 21, linear bearing 22, guide post 23, workbench 24, limiting cylinder 25, limit adjust spiral shell
Mother 26, connecting rod 27, servo motor 30, arc-shaped swing link 31, laser range sensor 32, greasing head 33, greasing head connection
Bar 34, locating rod 35, origin close switch 36 and contact switch 37.
Lubricating grease, which is sucked by vacuum pump from oil inlet, to be entered inside proportional valve；Proportional valve cylinder pushes spool to do straight line fortune
It is dynamic that lubricating grease is pushed into petroleum pipeline；The movement travel that bolt is used to adjust valve core is quantitatively adjusted, is risen by adjusting movement travel
To quantitative effect；Quantitative valve system and grease filling system installation are located on greasing crane；Guide post is fixed on workbench
On；Limiting cylinder is fixed on guide post, drives jacking system to do linear motion up and down by linear bearing and connecting rod, real
When existing greasing between greasing head and bearing height adjusting, limit adjusting nut plays limit and adjusts and fastening effect；Servo motor,
Origin is fixed on greasing upgrading frame close to switch and contact switch, is moved synchronously with crane；Arc-shaped swing link swashs
Ligh-ranging sensor, locating rod and greasing head are fixed in greasing head connecting rod, and greasing head connecting rod and servo motor are defeated
Shaft is connected, and is rotated back and forth by servo motor driving greasing head.Origin is close to switch for close between locating rod, with locating rod
0.5~1mm distance is kept, makes bright close to switch lamp, they are used to control the origin position of grease filling system, are driving servo motor
Origin position is returned after dynamic greasing head greasing.Laser range sensor is used to precisely find the position of greasing slot, and bearing is kept
The greasing trench bottom of frame is set as origin position, and range is set in ± 0.5mm, more accurately looks for realize than conventional fiber
Quasi- greasing position.Contact switch is used to keep the distance of 0.5mm between them close to arc-shaped swing link, look for a little for secondary,
Occur when laser range sensor is blocked by lubricating grease or pollutant, bearing positioning runout, greasing head loosen, note
Rouge head can be contacted with retainer ball pocket, and at this moment swing link is contacted with contact switch, make it is secondary look for a signal to be excited, prevent it is wrong
While the greasing signal missed, servo motor rotation driving laser sensor is forced to repeat to look for a little, until accurate find greasing slot
Position ability greasing, so as to avoid the instability problem of greasing quality in abnormal cases.It cannot achieve essence if being repeated as many times
Standard is looked for a little, then is picked out automatically by getting rid of the product of falling, and operator is reminded to check abnormal conditions in time.
Under normal circumstances, when bearing enters greasing station, first by the detecting laser beam bearing of laser range sensor 32
The greasing groove location of retainer transmits measuring signal if detection range does not meet the setting value of laser range sensor 32
It to servo motor 30, is rotated by a certain angle by the driving of servo motor 30, is set when the distance that laser range sensor 32 detects meets
When definite value, i.e., greasing groove location when, servo motor 30 stops rotating, and limiting cylinder 25 receives under action signal starts at this time
Drop when limiting cylinder 25 drops to setting position, can transmit a signal to proportional valve cylinder 10 and execution cylinder movement, proportional valve
12 valve core makes lubricating grease flow to greasing head 33 from oil transportation steel pipe 21 under the promotion of cylinder, inside last injection bearing, thus
Complete entire greasing process.
When generation laser range sensor 32 is blocked by lubricating grease or pollutant, deviation, greasing head 33 occur for bearing positioning
When the abnormal conditions such as loosening occur, greasing head 33 can touch bearing retainer ball pocket surface, at this moment due to not in the original of setting
Point position, circular arc swing link 31 are in contact with contact switch 37, and excitation is secondary to look for a signal, and the rotation of servo motor 30 is forced to be driven
Dynamic laser sensor 32 repeats to look for a little, until precisely finding greasing groove location, completes the greasing process under abnormal conditions.If laser
Distance measuring sensor 32 is repeated as many times and cannot achieve and precisely look for a little, then picks out automatically by getting rid of the product of falling, avoid unnecessary greasing generation
Waste and bad problem.
Compared with the prior art, the advantages of the utility model are: the essence that the utility model passes through laser range sensor
Standard looks for position, realizes and looks for a greasing more stable than conventional fiber；Secondly, being realized by arc-shaped swing link and contact switch
It is secondary precisely to look for the unstability for a little avoiding the lubricating grease waste and greasing quality that generate in abnormal cases.
