Embodiment
With reference to Fig. 1-Fig. 5, the entrucking special plane of a kind of car door outside plate automatic loading production line, comprise base 13, support and lifting table 1, support is fixedly connected with base 13 is vertical, support is made up of two root posts 7 and four cross bar welding, lifting table 1 is positioned at the front side of support, between lifting table 1 and support, it is provided with vertical panel 4, vertical panel 4 is arranged on before two root posts 7 of support by two road roller line slideways 5, every root roller line slideway 5 has two slide blocks, slide block is connected to the back side of vertical panel 4, vertical panel 4 passes through slide block, roller line slideway 5 is arranged on before bracket upright post 7, the aft end face of lifting table 1 is fixedly connected with the lower front of vertical panel 4, therefore, whole lifting table is mainly born by roller line slideway 5 by power, moment of torsion is distributed on four slide blocks of roller line slideway 5, being provided with motor 2 and step-down gear 3 thereof on vertical panel 4, step-down gear 3 connects twisted spur gear 15, and twisted spur gear 15 is meshed with the helical rack 14 being arranged in bracket upright post 7, and described helical rack 14 is vertically arranged and mutually parallel with roller line slideway 5. under the drive of motor 2, lifting table 1 can being made to move up and down, motor 2 adopts servomotor, has band-type brake function, such that it is able to realize lifting table 1 moment precise positioning.
In the present embodiment, only moving up and down by motor and step-down gear drive lifting table 1, it is difficult obviously to compare, therefore a counter weight device 20 is increased, counter weight device 20 is arranged on the rear side of two root posts 7, counter weight device 20 is attached on column 7 by twice guide path 21, and can move up and down, and is connected with two wireline 9 between counter weight device 20 with vertical panel 4, by being arranged on the pulley 24 above upper cross bar 25 in the middle of wireline 9, the weight of counter weight device can regulate according to the weight of platform. Lifting table overall weight is roughly equal with counter weight device weight, and such motor drives the necessary force of lifting of lifting table to be exactly two-part weight difference, effectively lowers the size size of motor.
In the present embodiment, owing to lifting table 1 adopts cantilever structure, therefore for lifting table 1 overall mechanical mechanism design there is strict requirement. In order to proof strength requirement, column 7 adopts the square tubes soldering of 120*120 size and becomes. Lifting table framework adopts the square tube weldering frame of 40*40 to assemble, and is divided into weldering frame 17 and lower weldering frame 16, and connection between the two adopts vertical rod and bolt to connect, and had both ensured the stability of platform weldering frame, and lifting table will have been caused too greatly to be out of shape because of intensity again. Distance between upper weldering frame 17 and lower weldering frame 16 is the height of lifting table 1, loads goods and is placed between weldering frame 17 and lower weldering frame 16 casing formed, the height of the lifting table 1 that can match according to the size design of different goods. Meanwhile, designing three oblique pull bars 10, the two ends of oblique pull bar 10 are fixedly connected with vertical panel 4 with upper weldering frame 17 respectively, and form trilateral structure, ensure the stability of lifting table 1 further.
In the present embodiment, also increase a screw mandrel device for horizontally pushing 11, screw mandrel device for horizontally pushing 11 comprises ball-screw 18, ball line slideway 19, push pedal 22 and horizontal pushes away motor 23, utilization is welded frame 17 ball-screw 18 and ball line slideway 19 are oppositely installed, push pedal 22 is fixed on ball-screw 18 and ball line slideway 19, push pedal 22 is driven or to move right by the horizontal motor 23 that pushes away to the left as power, the material being loaded in lifting table 1 can be transported to specify and highly again material be pushed away platform, be placed in other automatic equipment or place on the platform of goods.
In the design, before the upper cross bar 25 and sheer pole 26 of described support, be respectively equipped with upper limit position block 8 and lower position block 12, it is ensured that lifting table can not because of unexpected skid off movement travel outside. Correct position above and below arbitrary column 7 side of described support, is respectively equipped with limit sensors 6.
