Impact head-centralizing method by means of heigh and/or widening back recess that implements said tening and/or widening back recess and a device for centralizing impact head by means of heighteningmethod
The present invention relates to the field of machinery, and is particularly suitable for an impact head-centralizing method by means of heightening and/or widening back recess and a device for centralizing impact head by means of heightening and/or widening back recess that implements said method in the fields of mining or engineering machinery. The invention comprises a dual back recess guidance mechanism, an impact support mechanism, a drive mechanism, impact heads, etc. The dual back recess guidance mechanism comprises a dual rolling friction back recess structure and an impact guidance element, etc. The dual rolling friction back recess structure comprises an upper rolling friction grove, and a lower rolling friction groove. A power impact element drives the impact guidance element, etc. to reciprocate. The impact guidance element is disposed within the space of an external guidance roller. The impact guidance element increases the centralizing height of the impact head, and the rolling friction centralizes the reciprocating movement direction of the dual back recess structure and the impact guidance element.
