A method for rapidly assembling and disassembling a reciprocating impact tooth to a through hole tooth base and an impacting device with the through hole tooth base with the reciprocating impact tooth capable of being rapidly assembled and disassembled

Abstract

The invention belongs to the field of machinery and particularly relates to a method for rapidly assembling and disassembling a reciprocating impact tooth to a through hole tooth base and an impacting device with the through hole tooth base with the reciprocating impact tooth capable of being rapidly assembled and disassembled. The device comprises an insertion through hole reciprocating impact tooth, a reciprocating impact tooth through hole base, an insertion through hole reciprocating impact tooth handle, and the like. The insertion through hole reciprocating impact tooth handle is arranged in the reciprocating impact tooth through hole base, and is retained in a manner that the insertion through hole reciprocating impact tooth handle is retained against the reciprocating impact tooth through hole base via a tapered surface. A rotation-stopping device and the like are also arranged. The method and the device achieve rapid disassembly of the insertion through hole reciprocating impact tooth. The method and the device are practical and efficient, and expand the applications of a reciprocatingly impacting mining machine.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a method for quickly installing and dismounting a through-hole tooth seat and a reciprocating tooth punching impact device for quickly installing and dismounting a through-hole tooth seat. Background technique [0002] Because the existing mining machines, rock drills and breakers do not have a structure that allows the reciprocating punch handle to be exposed to the rear of the reciprocating punch seat hole relative to the reciprocating impact power output end, the original reciprocating punch handles are all inserted into blind holes. The reciprocating tooth seat and the blind hole reciprocating tooth seat are fixed. In order to prevent the reciprocating tooth shank from falling off from the blind hole reciprocating tooth seat, a stopper is set at the junction of the reciprocating tooth shank and the blind hole reciprocating tooth seat. , due to the strong reaction force generat...

[0002] Because the existing mining machines, rock drills and breakers do not have a structure that allows the reciprocating punch handle to be exposed to the rear of the reciprocating punch seat hole relative to the reciprocating impact power output end, the original reciprocating punch handles are all inserted into blind holes. The reciprocating tooth seat and the blind hole reciprocating tooth seat are fixed. In order to prevent the reciprocating tooth shank from falling off from the blind hole reciprocating tooth seat, a stopper is set at the junction of the reciprocating tooth shank and the blind hole reciprocating tooth seat. , due to the strong reaction force generated by the reciprocating impact on rock walls, coal walls, concrete walls, etc., the reciprocating punching handle must be seriously dislocated to the blind hole end of the reciprocating punching seat, causing the reciprocating punching handle to frequently push the stop piece Shearing or shearing deformation will cause the back-stop part to fail and the handle of the reciprocating punching tooth will fall off or the back-stop part will be deformed for a long time and it will be difficult to disassemble it, or the reciprocating punching tooth will not be able to be replaced because the back-stop part cannot be disassembled, resulting in production stoppage. The return part adopts the reciprocating punching taper handle and the reciprocating punching tapered blind hole seat to stop the retreat. The strong reaction force generated by the reciprocating impact on the rock wall, coal wall, concrete wall, etc. makes the reciprocating punching taper handle inevitably toward the reciprocating punching. The blind hole end in the conical blind hole seat moves seriously, causing the reciprocating punching taper handle and the conical surface of the reciprocating punching conical blind hole seat to lock, but the reciprocating punching can only be removed from the front end of the reciprocating tooth conical blind hole seat. The toothed taper handle makes it difficult to disassemble the reciprocating toothed taper handle by prying or knocking or pushing with a jack, or
