Description

Electromagnet 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 friction speed interlocking equipment 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 electromagnet 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；Previous power source is the electromagnetic control assembly installed in the outer upside of installation frame, and electromagnetic control assembly includes fixing Frame, static iron core, armature, iron core protection bolster, coil and coil driver, static iron core, buffer stopper, coil and coil drive Circuit is in fixed mount；Static iron core is " E " character form structure, and its openend is set down；Iron core protection bolster is located at quiet Iron core top；Coil is enclosed within static iron core, and coil driver is connected with coil electric；Armature is matchingly being located at static iron core just Lower section, armature lower end is connected with active tooth bar upper end；Active sliding block is provided with active sliding block toward drop-down extension spring；Driven cunning Block is provided with driven sliding block toward the extension spring for pulling up；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.Linkage is cranked arm and can bypass workpiece, realizes linkage from top to bottom.

As the pulling force that the explanation of above-mentioned technical proposal, extension spring are produced, active sliding block and driven sliding block is allowed to compress in opposite directions, electricity The static iron core and coil of magnetic control component produce upward attraction, and extension spring is stretched and active sliding block is promoted and driven sliding block phase It is anti-to open.Only needing to a power source promotes active tooth bar to move along a straight line, and linkage is moved in the rotation of active rack drives linkage gear The driven tooth bar of gear driven also does opposite with active tooth bar or opposite linkage linear motion, but due to both tooth pitches not phase Together, both movement velocitys are also differed, so that, active tooth bar and driven rack drives active sliding block and driven sliding block are moved, It is capable of achieving friction speed linkage.Due to being single driving power source, control is more convenient, and volume be can be made smaller, and is passed by machinery Move to realize the linkage of friction speed, control more convenient, energy-conserving and environment-protective, the maintenance of production cost, use cost are low.By changing The size for becoming tooth pitch can change speed ratio, namely within the unit interval, active sliding block and driven sliding block make opposite or opposite fortune It is dynamic, but both every trade journeys are different.Wherein, external link gear is connected with active sliding block and driven sliding block and be capable of achieving linkage work( Energy.

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.
