Description
Technical field
The utility model relates to casting field turnover device, specially a kind of box moulding line flask overturning device.
Background technique
Mould rollover unit is one of the device that must be configured in moulding line production technology, and mould rollover unit is to produce moulding
Sandbox on line carries out 180 ° of overturnings, and it acts as the sandbox surface spill sands that moulding machine can have been made to type by sandbox overturning
Cleaning；The technique of the technique requirement for meeting milling cast gate simultaneously, boring stomata, cope or drag box mould assembling requires and the technique of knockout
It is required that etc..
Existing mould rollover unit mechanism form is mostly divided into: drum-type and convertible.
Drum-type mould rollover unit overturning be to be overturn along sandbox direction of motion axis, driving method be motor reducer or
Hydraulic motor is by chain or gear drive, the disadvantage is that complete machine structure is big, manufacturing cost is high, control positioning accuracy is low, Er Qieyan
Direction of motion axis overturn sandbox when, sandbox spill sand is easy on the idler wheel for falling and accumulating in mould rollover unit, cause sandbox and
The sluggishness and abrasion of mould rollover unit idler wheel.
Convertible mould rollover unit haves the shortcomings that control testing agency is more, structure is complicated, failure is high.
Summary of the invention
The utility model there are positioning accuracies in order to solve existing turnover device easily sluggish abrasion of poor, idler wheel and structure is multiple
The problem of miscellaneous, high failure rate, provide a kind of box moulding line flask overturning device.
The utility model adopts the following technical scheme that realization: a kind of box moulding line flask overturning device, including
Rack and the bearing block being arranged at left and right sides of rack are provided with bearing and the rotary sleeve in bearing in bearing block,
Head rotary extension locating shaft corresponding with mouldinng box trunnion hole site, the tail portion of rotary extension locating shaft are provided in rotary sleeve
It is respectively connected with the drive cylinder fixed with rack, is respectively and fixedly provided with the rollover stand covered on its side wall, two rollover stands on rotary sleeve
Adjacent side be provided with the corresponding two rows idler wheel in position, be provided on the right side of rollover stand on the rotary sleeve of right side
Driven gear；It is additionally provided with servo motor on the right side of rack, the snail connecting with the two is provided between servo motor and driven gear
Worm and gear retarder is provided with angular transducer on driven gear, position sensor is arranged on the rollover stand of right side.
When carrying out overturning operation, sandbox sequentially enters the rolling of rollover stand two rows under the effect of mo(u)lding line sandbox pushing mechanism
Between wheel, when position sensor detects sandbox, sandbox movement stops, and drive cylinder is stretched out, and pushes rotary extension positioning axial
Medial movement is inserted into the axis hole at sandbox both ends；Then servo motor drives driven gear to drive by worm type of reduction gearing
Rotary sleeve and rollover stand positioned at right side drive sandbox to make rotating motion along rotary extension positioning axis center, are located at left side and overturn
The rotation of frame is under the drive of sandbox with the driven overturning in the center of rotary extension locating shaft；Servo motor can realize turning over for sandbox
Turn starting, accelerate, slow down, stopping movement, after sandbox is rotated in place, drive cylinder retracts and rotary extension locating shaft is driven to contract
It returns, exits the axis hole at sandbox both ends, complete overturning, overcome existing turnover device there are positioning accuracies that poor, idler wheel is easily sluggish grinds
Damage and the problem of structure is complicated, high failure rate.
The sliding shaft sleeve with rotary sleeve tensioner is provided between rotary extension locating shaft and rotary sleeve.
In structure design by sliding shaft sleeve and rotary sleeve cooperation realize rotary extension locating shaft radial limit and
Axially free connection.
The utility model drives driven gear to be driven using servo motor driving worm type of reduction gearing, realizes reduction and passes
Dynamic and detection requirement；And rotational positioning is reliable, has self-locking function, reliably ensure that when servo motor stops
Sandbox and flip portion will not rotation, and then failure rate is greatly reduced；The change of sandbox positioning and method of clamping simultaneously, ring
Section is simplified, and the mo(u)lding line for being particularly suitable for the bigger sandbox of length and width uses.
