Description
Technical field
The utility model belongs to machinery assembling and use technical field of tools, relates in particular to a kind of circle sieve vibrator that shakes and overhauls special implement.
Background technology
The round sieve that shakes is a kind of ore dressing screening plant of present domestic extensive use.This equipment is mainly by formations such as device of shifting block type screen box, vibrator, transmission system, vibration insulating system and screen clothes.And the critical piece of vibrator has the vibrator overcoat 17 of outer ring boss 18 shown in accompanying drawing 2, the ladder rotating shaft 15 that is connected with bearing group therewith of the bearing group 16 that is connected of vibrator overcoat 17 therewith.Because bearing group is in the duty of rotation at a high speed, vibrations for a long time; And cooperating between bearing group and ladder rotating shaft and the vibrator overcoat is generally the higher interference fits of precision; Add and be in vibrating state for a long time; So bearing belongs to consumable accessory, must regularly carry out maintaining or more renew part.But, be not easy to carrying, dismounting and assembling because the volume and weight of vibrator is all bigger.Also can't use conventional instrument and conventional directly pulling type method dismounting, thereby when dismounting, the maintenance worker is many to knock the parts that are connected with bearing repeatedly with sledgehammer, perhaps adopts destructive cutting method that bearing is cut apart.Maintenance process is wasted time and energy.And this destructive method for dismounting is easy to cause the distortion of vibrator overcoat and the cut injury of ladder rotating shaft, the service life of reducing overcoat and ladder rotating shaft.When the assembling vibrator, bearing need manually be set in the ladder rotating shaft, uses then and knocks about sledgehammer on the tram that moves it the ladder rotating shaft, and the ladder rotating shaft that has bearing group afterwards need use the same method again and be installed in the vibrator overcoat.Therefore knocking the process middle (center) bearing because axially loaded is inhomogeneous; Can't guarantee parallel moving, the wearing and tearing that between ladder rotating shaft, vibrator overcoat, bite easily cause the damage of vibrator assembly; Reduce the smoothness even the damage of inter-module; Cause vibrator to reduce service life, cause the tremendous economic loss, increase the preparation equipment cost.
Summary of the invention
The purpose of the utility model is to provide circle a kind of simple in structure, easy to operate, time saving and energy saving to shake and sieves vibrator maintenance special implement.
The purpose of the utility model realizes through following technical proposals:
The circle of the utility model shakes and sieves vibrator maintenance special implement; It is characterized in that by round-meshed base platform, be fixed on two vertical pillars on this base platform, respectively two up-down pressing plates that vertical pillars is slidingly connected therewith; Be located at the jack on this up-down pressing plate; Be located at the adjustment limiting plate of this jack top, adjust the screw rod that limiting plate is fixedly connected therewith, difference is the fixedly top board and the clamp nut of screw flight connection therewith; Two uprighting springs that two ends are connected with the up-down pressing plate with described fixedly top board respectively; Be placed on the bearing propelling sleeve of tearing open for use on the base platform and form with dress bearing propelling sleeve, described fixedly top board is fixedly connected with the top of described two vertical pillars, and described two vertical pillars are arranged symmetrically in the centre bore both sides on the said base platform; Described two uprighting springs are arranged symmetrically in described jack both sides, described jack.Circular hole on screw rod and the said base platform is same center line.
Described up-down pressing plate is provided with the peripheral frame of fixing said jack position.
Described uprighting spring is the extension spring that two ends have connector respectively.
The advantage of the utility model:
1) the utility model is simple in structure, and the easy access workman uses, and has reduced working strength of workers significantly, by former dismounting and assemble a vibrator and need 6 hours, can shorten to 1.5 hours, has improved overhaul efficiency effectively;
2, use the utility model; Can effectively avoid vibrator when dismounting and assembling; The maloperation that occurs causes rotating shaft damage and overcoat distortion, avoids the wearing and tearing that bite that take place between bearing and vibrator overcoat, the rotating shaft, the smooth smoothness of assurance assembly; Effectively prolong the life cycle of vibrator, reduced the preparation equipment cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the critical piece sketch map of the application vibrator of the utility model.
The specific embodiment
The specific embodiment below in conjunction with description of drawings the utility model.
Like Fig. 1, shown in 2: the circle of the utility model shakes and sieves vibrator maintenance special implement; It is characterized in that by the base platform that has circular hole 12, be fixed on two vertical pillars 3 on this base platform, respectively two up-down pressing plates 4 that vertical pillars 3 is slidingly connected therewith; Be located at the jack 6 on this up-down pressing plate; Be located at the adjustment limiting plate 10 of this jack top, adjust the screw rod 8 that limiting plate is fixedly connected therewith, respectively the fixedly top board 11 and clamp nut 9 that are threaded of screw rod 8 therewith; Two uprighting springs 5 that two ends are connected with the up-down pressing plate with described fixedly top board respectively; Be placed on for use tearing bearing propelling sleeve 13 open and adorn 14 compositions of bearing propelling sleeve on the base platform 2, described fixedly top board 11 is fixedly connected with the top of described two vertical pillars 3, and described two vertical pillars are arranged symmetrically in the circular hole both sides on the said base platform; Described two uprighting springs are arranged symmetrically in described jack both sides, described jack.Circular hole on screw rod and the said base platform is same center line.
Described up-down pressing plate 4 is provided with the peripheral frame 12 of fixing said jack position.
Described uprighting spring is the extension spring that two ends have connector 7 respectively.
When using the utility model to dismantle the inefficacy bearing on the vibrator, the overcoat that has boss on the vibrator to be put in the circular hole 1 on the base platform 2, the boss of overcoat is stuck on the edge of circular hole 1; Be enclosed within the ladder rotating shaft 15 on the vibrator tearing bearing propelling sleeve 13 open, and upper surface exceeds the upper end of ladder rotating shaft 15, start jack 6 after; Up-down pressing plate 4 moves down; And slowly to tearing bearing propelling sleeve 13 application of forces open, move down thereby drive ladder rotating shaft 15, finally break away from bearing inner race.
When use the utility model install on the vibrator more renew bearing the time; Equally the overcoat that has boss on the vibrator is put in the circular hole 1 on the base platform 2, the boss of overcoat is stuck on the edge of circular hole 1, at first bearing to be installed is aimed at external trepanning; The bottom that to adorn bearing propelling sleeve 14 then abuts against on the bearing upper surface; After starting jack 6, up-down pressing plate 4 moves down, and slowly to dress bearing propelling sleeve 14 application of forces; Move down thereby drive ladder rotating shaft 15, finally get in the overcoat of vibrator.
Use the utility model dismounting, bearing is installed, to the uniform force application of bearing, do not injure parts, the installation or the maintenance that are particularly useful on the main equipment are time saving and energy saving especially, are adapted at wideling popularize in the bargh.
