Description

Novel synchronous friction speed linkage
Technical field
The utility model is related to a kind of interlocking equipment, more particularly to a kind of different friction speed interlocking equipment of linkage speed.
Background technology
Traditional clamp system, strainer or the different friction speed interlocking equipment of linkage speed, frequently with dual drive power The mechanism in source, power source is frequently with cylinder, motor etc..Its defect is, because needing two power source actions of control simultaneously, control system System is relative complex, causes the poor reliability of mechanism's linkage action, and equipment volume is big, and power source buying and use cost are high, unfavorable In energy-conserving and environment-protective.
The content of the invention
The defect that the utility model exists for the friction speed interlocking equipment of above-mentioned dual drive power source, and a kind of performance is provided More preferably, small volume, the novel synchronous friction speed linkage of single driving power source of low cost.
To achieve the above object, the scheme that the utility model is taken is:A kind of novel synchronous friction speed linkage, including peace Frame up frame, and is fixed on the power source on installation frame;It is characterized in that:The installation frame left and right sides is provided with leading of be arrangeding in parallel Rail, from right to left respectively active guide rail and driven guide rail;Active guide rail and driven guide rail are provided with sliding block, respectively actively sliding Block and driven sliding block;Active sliding block and driven sliding block inner side linking relative to each other have the tooth bar be arrangeding in parallel, respectively actively The tooth pitch of tooth bar and driven tooth bar, active tooth bar and driven tooth bar is differed;Being provided between active tooth bar and driven tooth bar to turn Dynamic linkage gear, gear is arranged on installation frame by bearing;Active tooth bar and driven tooth bar respectively with the linkage gear Engagement connection;The power source is the cam pack installed in the outer upside of installation frame, and cam pack includes that fixed mount, rotation drive Dynamic device, cam, slide bar, linear bearing, rotating driving device are stretched into located at fixed mount outside, the drive shaft of rotating driving device To in fixed mount, cam is arranged on the driveshaft end of rotating driving device, and linear bearing is arranged at cam lower section and is fixed on Fixed mount, in linear bearing, slide bar upper end is provided with runner to jack rod sleeve, and the slot rolling of slot rolling, runner and cam is provided with the middle of cam Contact, slide bar lower end is connected with active tooth bar upper end;Active sliding block is provided with active sliding block toward the extension spring for pulling up;Driven cunning Block is provided with driven sliding block toward drop-down extension spring;The linking of driven sliding block lower end extends downwardly into installation frame lower section, then Prolong liter again forwards, followed by the lower section extension behind the center for extending right to installation frame, then to installation frame but not The linkage contacted with installation frame is cranked arm.
Used as the explanation of above-mentioned technical proposal, extension spring produces pulling force, allows active sliding block and driven sliding block conversely to open, cam The cam high point of component produces downward thrust, and extension spring is stretched and active sliding block is promoted and driven sliding block is compressed in opposite directions.Linkage Cranking arm can bypass workpiece, realize linkage from top to bottom.Only needing to a power source promotes active tooth bar to move along a straight line, active tooth bar Linkage gear rotation is driven, dynamic linkage gear drives driven tooth bar also to do linkage straight line fortune opposite with active tooth bar or opposite It is dynamic, but because both tooth pitches are differed, both movement velocitys are also differed, so that, active tooth bar and driven rack drives Active sliding block and driven sliding block are moved, you can realize that friction speed links.Due to being single driving power source, control is more convenient, volume Can be made smaller, the linkage of friction speed is realized by machine driving, control more convenient, energy-conserving and environment-protective, production cost Maintenance, use cost it is low.By changing speed ratio by the size for changing tooth pitch, namely within the unit interval, active sliding block Make opposite or move toward one another with driven sliding block, but both every trade journeys are different.Wherein, external link gear and active sliding block and from Movable slider connection is capable of achieving linkage function.
Used as the improvement of above-mentioned technical proposal, foregoing linkage gear is two in-line gears compositions of different sizes, wherein, Gear wheel is engaged with active tooth bar, and little gear is engaged with driven tooth bar.Angular speed when being rotated due to big little gear is identical, but line Speed is different, and the speed for being delivered to tooth bar is also different, therefore can realize different linkage speeds.
Used as further illustrating for above-mentioned technical proposal, foregoing guide rail is dovetail guide, and sliding block is dovetail groove sliding block.
Used as the improvement of above-mentioned technical proposal, aforementioned rack bottom side is provided with chute, and the roller for supporting tooth bar is provided with chute, Roller is fixed on installation frame.Chute and roller are matched, and can not only support that tooth bar is acted on, moreover it is possible to play rack stroke spacing Effect.
From the above mentioned knowable to scheme, the utility model has the advantages that:Scientific structure, simple and practical, construction is firm, easily system Make, small volume is easy to assembly, low cost, only can just realize friction speed linkage action with a driving power source, be easily controlled, It is safe and reliable, clamp system, strainer or the different friction speed interlocking equipment of linkage speed can be widely used in, facilitate correlation to set Standby Automated condtrol, with larger application prospect.
