Pin rod machining device for machining elevator safety pins

Abstract

The invention discloses a pin rod machining device for machining elevator safety pins, and relates to the technical field of machining of elevator safety pins. The pin rod machining device for machining the elevator safety pins comprises a grinding machine. The grinding machine comprises a housing. A first fixed rod is disposed in the housing. The lower surface of the first fixed rod and the lowersurface of the interior of the housing are fixedly connected together. A grinding device is disposed in the grinding machine. The grinding device comprises a motor. A motor rotating shaft is disposedon the back side face of the motor. A first transmission shaft is fixedly connected to the back side face of the motor rotating shaft. The outer side face of the first transmission shaft is rotationally connected with the front face and the rear face of the first fixed rod in a penetrating manner. The first transmission shaft rotates to make a second transmission shaft to rotate through a transmission belt so as to make a polishing wheel rotate, in this way, the polishing wheel is made to rotate, a to-be-machined pin rod is pushed towards the grinding wheel when the polishing wheel rotates, the surface of the to-be-machined pin rod is ground to be more smooth, and it is avoided that assembling fails due to the unsmooth surface of the pin rod.

Description

technical field [0001] The invention relates to the technical field of elevator safety pin processing, in particular to a pin rod processing device for elevator safety pin processing. 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 that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical tran...

AI Technical Summary

Problems solved by technology

[0003] The elevator safety pin is a pin rod located on the elevator safety gear. Its function is to stop the car in an emergency when the elevator speed exceeds the limit speed set by the elevator speed limiter, or when the suspension rope breaks and relaxes. And it is a safety device clamped on the guide rail. Now the surface of the elevator safety pin is not smooth and the cloak is easy to cause assembly inconvenience and installation size difference, and it is easy to cause the internal elevator safety gear to fail, and the risk factor is large. Therefore There is an urgent need for a pin rod processing device for elevator safety pin processing to process the cape on the pin rod and smooth the surface of the pin rod
