Punching device capable of achieving stable clamping and used for elevator accessory machining

Abstract

The invention discloses a punching device capable of achieving stable clamping and used for elevator accessory machining. The punching device comprises a base, the rear side of the top of the base is fixedly connected with a punching machine through a connecting plate, the front side of the top of the base is provided with a transmission sleeve, the front side of the inner wall of the transmission sleeve is fixedly connected with a motor, and the output end of the motor is fixedly connected with a two-way screw rod. The motor drives a first pressing plate to be pressed on the surface of an accessory through the two-way screw rod for front-back limiting, then an electric cylinder drives a second pressing plate and a positioning mechanism to be pressed on the surface of the accessory through a square sleeve and a sliding sleeve, and left-right positioning and up-down positioning of the accessory are achieved; and finally, the motor drives a rotating mechanism to stably clamp the pipe fitting through a two-way screw rod and the first pressing plate, so that the punching device has the advantage of stable clamping, and the problems that an existing punching device only conducts clamping and fixing through two movable clamping plates, the fixing effect is poorer, meanwhile, the pipe fitting is inconvenient to clamp, and a drill bit is easy to be damaged due to tilting are solved.

Description

technical field [0001] The invention relates to the technical field of elevator accessory processing, in particular to a punching device for elevator accessory processing with stable clamping. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° from the plumb line. Continuous operation on the crawler belt, commonly known as escalator or moving sidewalk, serves as fixed lifting equipment for specified floors. [0003] In the process of elevator accessories processing, a punching device is used for punching, but the existing punching device is only clamped and fixed by two movable splints, the fixing effect is poor, and it is not convenient to clamp the tubular fittings , It is prone to warping and damage to the drill bit. Contents of the invention [0004] I...
