Abstract

The utility model relates to a right angle trajectory curve connecting rod type sprayer, which comprises a gearbox unit, a sprayer, a continuous motion bar and a limit lever; wherein, the gearbox unit is driven by a motor to transmit a dynamic rotating bar and bring along the continuous motion bar with the nozzle of the sprayer to swing, and meanwhile the limit lever is connected with the continuous motion bar and drives the limit lever through an eccentric wheel to make both the continuous motion bar and the limit lever move and be driven by the eccentric wheel to swing in a fixed speed ratio (the fixed speed ratio is conversed in about one to four). The utility model is characterized in that the continuous motion bar swings ninety degrees and the eccentric wheel swings three hundred and sixty degrees so that the nozzle of the sprayer forms a right angle trajectory curve (close to linear moving) to reach the uniform spraying effect of the inner surfaces of two semimodules.

Description

The link-type spraying machine of tool right angle geometric locus

Technical field

The utility model relates to a kind of spraying machine, refers to that especially the nozzle of sprayer forms the interlinked mechanism of a kind of right angle geometric locus displacement.

Background technology

The present employed sprayer of die casting machine, in order to cooperate the folding repeatedly of die casting machine mould, all design the interlinked mechanism of interlock sprayer displacement at the sprayer place, these interlinked mechanisms can be divided into two kinds haply: one for being done the moving mechanism of X, y-axis shift, for being the travel mechanism that fulcrum is made circular curve with connecting rod one end by pneumatic cylinder control, the two is all in order to reach the spray cloth that moves back mat nozzle, to remove the impurity on die casting machine two half module mould surfaces, reach spray cloth mould release so that die casting is used next time.

And in above-mentioned known design mechanism, design with the pneumatic cylinder start, because of the bigger space of the mobile need of X, Y-axis, and the excessive height of Y-axis, for the factory building space and highly have for the dealer of limit, and can't be suitable for, and utilize the mechanical arm start of X, Y-axis, also quite high on cost, for the dealer also be one greatly the burden.

The mechanism design system of another link-type further improves the spraying machine travel mechanism that designs at above-mentioned known disadvantage, though this mechanism can significantly reduce cost, right its shortcoming also produces, it mainly is to do circular-arc swing on the frame because of this system of mechanism is hubbed on connecting rod one end, so that nozzle enters the operation of cleaning and spraying the cloth mould release between two half modules, but, because of its spraying deformation trace is circular-arc, therefore for same half module tool, too approaching sometimes, but sometimes again can be too away from, second half mould also has same condition so relatively, this situation will cause because of the unequal uneven phenomenon of spraying that produces of nozzle distance two half modules distance, in addition, behind mold exchange more, the position after two half modules are opened is different, can collide mould when also causing this mechanism to do circular-arc swing, cause unnecessary component damage.

Summary of the invention

It is one with low cost that the purpose of this utility model is to provide, and can overcome the spraying machine of the above-mentioned design shortcoming of known facility simultaneously.

For achieving the above object, solution of the present utility model is: the link-type spraying machine of a kind of tool right angle geometric locus, it comprises: a motor and one and the decelerator of its interlock, the output shaft of this decelerator is attached at an end of trace, and the eccentric wheel that output shaft links for gag lever post one end by the transmission of power interlock after the speed change one in addition; One sprayer and most blast tube that is attached at sprayer, this sprayer are provided with a pedestal for trace and gag lever post binding; One trace, an end are articulated on the pedestal of sprayer, an end and output shaft interlock; One gag lever post, the pedestal of an end and sprayer articulates, and an end connects with eccentric wheel with the beat with its rotation, advances the displacement row Jing that drives sprayer with the control trace, and the motion track that reaches the rose pipe is a right angle geometric locus; This trace and gag lever post were with about 1: 4 (turning cylinder: ratiometric conversion eccentric wheel), generation trace swing 90 degree, then eccentric wheel swing 360 degree; This trace one end more is provided with a compression spring, and when trace was swung, this compression spring pressurized produced a bounce, in order to the supplemental support trace, also alleviates the torsion of motor.

Owing to adopted such scheme, the utlity model has following advantage:

1, the utility model increases eccentric wheel apparatus, four connecting rods that tradition is known produce the design of arc track, change into the design of the utility model single shaft right angle orbiting motion, and the circular arc radian that can effectively avoid the dangerous of mister head collision mould and improve traditional design causes the uneven critical defect of both sides mould distance, to reach nozzle to the both sides mould uniform practical function of spraying.

2, the utility model utilizes the trace motion mechanism design of linkage with the known V of tradition, Y-axis, change into the utility model single shaft right angle orbiting motion, can effectively reduce acquisition cost, can solve the conventional designs shortcoming simultaneously again, effectively improve product and produce effect and industrial competitiveness.

3, the utility model only need utilize a motor, both can control whole displacement mechanism motion, and speed and position that the nozzle track is moved are variable, to reach desirable spray effect.

4, the utility model can effectively reduce the height that is provided with of plant, and reduces the requirement to factory building height, so can improve user's acceptance.

The specific embodiment

The utility model spraying machine comprises: a gearbox group 1, a sprayer 2, a trace 3 and a gag lever post 4, this gearbox group 1 is to be driven by a motor 11, drive trace 3 with its rotary power output shaft 12, this trace 3 end in addition is the pedestal 21 that is linked to sprayer 2, trace 3 is swung together with the nozzle 22 of sprayer 2, simultaneously, other establishes a gag lever post 4 and is attached at the eccentric wheel 13 that the moving affair output shaft 12 of rotation sees through a speed change interlinked mechanism institute interlock, and gag lever post 4 is held the pedestal 21 that then is attached at sprayer 2 in addition.When moving to produce trace 3, gag lever post 4 also moves thereupon, and be subjected to ordering about of eccentric wheel 13, make trace 3 different with the speed of gag lever post 4 swings, with about 1: 4 (turning cylinder: ratiometric conversion eccentric wheel), produce trace 3 swings 90 degree, then eccentric wheel 13 is swung 360 effects of spending, so cause the nozzle 22 of sprayer 2 to form a kind of right angle geometric locus, its curve moves similar known X-axis of when beginning, second half section is the motion track of similar known Y-axis then, that is near the moving of straight line, so can reach the effect to the interior die face even spraying of two half module tools.

End at above-mentioned trace 3 more can be provided with a balancing weight 31 (or compression spring), and when trace 3 swings, these balancing weight 31 pressurizeds produce a bounce, in order to supplemental support trace 3, also alleviate the torsion of motor 11.
