Abstract
The utility model relates to a roller pressure plate assembly structure. After gear sleeves are assembled, the roller pressure plate assembly structure is punched by a drilling machine for assembling a safety pin, a hole is opened at one end of the safety pin for assembling a cotter pin so that the safety pin is prevented from automatically dropping out during rotation when the safety pin is abraded, and a centering device comprises a trapezoid centering weight and a connection seat and is matched with a shaft end surface to perform guiding and positioning actions. Accordingly, the roller pressure plate assembly structure has the advantages of being simple in structure, high in work safety, long in service life and the like.
Description
Technical field
The utility model relates to a kind of seamless steel pipe device structure, especially a kind of roll pressing plate assembly structure.
Background technology
At present, the roll follower bolt is M16, in process of production; The tooth cover is bigger with the axle backlash, because shake causes bolt looseness for a long time, the universal drive shaft that drives the roll running drops; Not only influence rhythm of production and output, and the waste natural gas etc., equipment is caused great influence.
Summary of the invention
The purpose of the utility model is to change the drawback that roll assembling bolt is loosening and universal drive shaft drops, thereby designs a kind of easy to assembly, long service life, safe roll pressing plate assembly structure.The technical scheme of the utility model is so to realize:
A kind of roll pressing plate assembly structure comprises tooth cover, centralising device, radially runs through a safety pin in the tooth cover, and said safety pin proximal end place is provided with a pin-and-hole, is provided with split pin in it, and said centralising device comprises trapezoidal centering piece and Connection Block.
As preferably, said safety pin top is provided with a block.
The roll pressing plate assembly structure of the utility model design, tooth cover assemble the safe bearing pin of back drilling machine punching assembling, and the safety pin shaft end is opened an aperture fitting opening pin, and wearing and tearing back safety pin drops automatically when preventing to rotate, and is simple in structure, safe; Centralising device comprises trapezoidal centering piece and Connection Block, cooperates with axial end and plays about guide-localization.Therefore the utlity model has simple in structure, characteristics such as job security is high, long service life.
Description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing,, do further bright specifically to the technical scheme of the utility model through embodiment.
Embodiment: with reference to accompanying drawing, a kind of roll pressing plate assembly structure comprises tooth cover 5, centralising device 3; Radially run through a safety pin 1 in the tooth cover 5, said safety pin 1 top is provided with a block 7, and the proximal end place is provided with a pin-and-hole 6; Be provided with split pin 4 in it, in case safety pin drops; Said centralising device 3 comprises trapezoidal centering piece 8 and Connection Block 9, cooperates the guide-localization effect of playing with axial end.
