The present invention relates to a kind of electric extension tongs.
Background technology
When this type of large ring (5-7 spare initial corner) heat treatment, often adopted the lifting of chain or steel rope (rope) to go into the pond in the past, because colluding, rope (rope) hangs of the rapidly influence of cooling of treatment temperature difference to workpiece, hot-cured hardness generation localized variation, stress is concentrated relatively, bring certain influence to product, especially bigger to large-scale precision ring potential impact, need to solve the stealth influence that this class problem is brought to product design, must thoroughly solve this technical matters.
Summary of the invention
The invention provides a kind of electric extension tongs, it has not only improved work efficiency greatly, and the quality that the secondary processing of product is handled improves greatly.
The present invention has adopted following technical scheme: a kind of electric extension tongs, it comprises caliper, top at caliper is provided with suspension ring, described caliper comprises support, on support, be provided with electrical motor, reductor, transmission gear I and transmission gear II, electrical motor by reductor and transmission gear I for being in transmission connection, on support, also be placed with balance in roll beam and balance in pitch beam, balance in roll beam and balance in pitch beam intersect mutually, transmission gear I is positioned on the point of crossing of balance in roll beam and balance in pitch beam, the balance in roll beam is divided into two sections transverse beams by transmission gear I, the balance in pitch beam is divided into two sections longitudinal beams by transmission gear I, all be provided with drive lead screw in two sections transverse beams of balance in roll beam and on two sections longitudinal beams of balance in pitch beam, one end of every drive lead screw is provided with transmission gear II and transmission gear I for being in transmission connection, on the main body of each drive lead screw, be with the slip arm, the bottom of slip arm is provided with clamp, and electrical motor passes through reductor successively, transmission gear I, transmission gear II and drive lead screw drive the slip arm and move on transverse beam or longitudinal beam.
After intersecting mutually, described balance in roll beam and balance in pitch beam be " ten " font.The slip arm that the drive lead screw that is respectively equipped with in two sections transverse beams of described balance in roll beam is with is symmetrical.The slip arm that the drive lead screw that is respectively equipped with on two sections longitudinal beams of described balance in pitch beam is with is symmetrical.Described transmission gear I and transmission gear II are set to crowngear I and crowngear II respectively, and the diameter of crowngear I is greater than crowngear II, crowngear I and crowngear II in same plane 90 ° each other.Both sides are respectively by preceding supporting base and rear branching holder supporting before and after the described every drive lead screw.Described reductor is the vertical shaft type worm reduction gear.
The present invention has following beneficial effect: it is propulsion source that the present invention adopts electrical motor, be equipped with the retarder speed governing, adopt the biography of one big four little crowngear deceleration displacement to return mode, make and hang the back of the body and on equalizing bar, reach rational clamping travel line speed and corresponding Clamping force at the slip arm, the quality that has improved work efficiency greatly and the secondary processing of product is handled.The present invention drives clamp by the slippage on equalizing bar of slip arm and inserts and puts, it can forward and reversely be regulated, thereby reach difformity, different demands, the adjusting of different occasions and application, and also caliper is from workpiece bottom supporting workpiece, will all ream in this areal of support machining process afterwards, because heating and quick cooling process are the whole ring states of keeping in balance, guaranteed the uniform quality of workpiece periphery, the hardness equalization.
