Abstract
The utility model discloses a breaking-in mechanism for a contacting finger of a breaker. A contacting finger fixing table and a sider corresponding to the contacting finger fixing table are arranged on a frame, a breaking-in head device is arranged on the slider corresponding to a contacting finger fixing station on the contacting finger fixing table, and a rotary linear reciprocation driving mechanism connected onto the slider is used for driving the slider to reciprocate along a direction perpendicular to the contacting finger fixing table. The slider is driven by the rotary linear reciprocation driving mechanism to drive the breaking-in head to simulate plugging and pulling of a contacting finger and a moving contacting head, and the contacting finger is compressed to contact with the moving contacting head, scratching probability of parts can be reduced, surface condition of the contacting finger can be improved, dropping of sliver scrapes in utilization after the contacting finger is plated by silver can be reduced, product quality can be protected and ensured, assembly efficiency can be improved, and cost is reduced.
Description
Technical field
The utility model relates to a kind of circuit breaker fixed contact fingertip break-in mechanism.
Background technology
The static contact finger that uses on the existing open type SF6 circuit breaker product needs silver-plated after machine work, but because the limitation of machine work and silver plating process causes its surface quality can not satisfy the instructions for use of product, make fixed contact and moving contact phenomenon appears scratching between dynamic/static contact when cooperatively interacting easily, causing between the dynamic/static contact is not sufficient face contact, but point, line contact, cause between the dynamic/static contact resistance bigger, influence the electric conductivity between the dynamic/static contact, and fall silver bits phenomenon on the fixed contact and also happen occasionally.
The utility model content
The purpose of this utility model is: a kind of circuit breaker fingertip break-in mechanism is provided, occurs scratching, causing the bigger phenomenon of resistance in the prior art between the dynamic/static contact easily to solve when closing a floodgate contact.
The technical solution of the utility model is: a kind of circuit breaker fingertip break-in mechanism, comprise frame, the slide block that frame is provided with the fingertip fixed platform and is oppositely arranged with this fingertip fixed platform, fingertip on the slide block on the corresponding fingertip fixed platform fixedly station is provided with the break-in head unit, is connected with the driving sliding block edge perpendicular to the reciprocating rotation of fingertip fixed platform direction-linear reciprocation driving mechanism on described slide block.
Described rotation-linear reciprocation driving mechanism comprises the motor driver that is fixed on the frame, radially be fixed with initiatively eccentric wheel on the output shaft of motor driver, on a side end face of described slide block, be rotatably equipped with the coaxial engaged transmission of this active eccentric wheel two by movable eccentric wheel, initiatively eccentric wheel is identical with eccentric throw with two passive eccentric diameters, two are located at initiatively eccentric both sides up and down by movable eccentric wheel along the glide direction branch of slide block, described upward close mutually when slide block is in low level with the eccentric rotating shaft of active, described close mutually when slide block is in a high position by movable eccentric wheel down with the eccentric rotating shaft of active by movable eccentric wheel.
Corresponding its reciprocating longest path offers vertical slotted hole on described slide block, described motor driver is arranged on a side of slide block, its output shaft extends axially the slotted hole that passes slide block, and described two are rotated by movable eccentric wheel and to be assemblied on the opposite side end face of slide block away from motor driver.
Described fingertip fixed platform is slidedly assemblied in the pilot hole of corresponding setting on the frame by lead, is provided with height adjuster between fingertip fixed platform and frame.
Circuit breaker fingertip break-in of the present utility model mechanism drives the plugging condition of break-in head mould plan fingertip and moving contact by slide block by rotations-straight line driving mechanism, the extruding fingertip, make it to reach the effect that contacts with the movable contact women's head-ornaments, reduce the probability that parts scratch, and improve the surface state of fingertip, in use fall silver bits phenomenon after the minimizing fingertip is silver-plated, for product quality escorts, improve efficiency of assembling, thereby reduce cost.
