Background technology
Electric pick is to be the double insulation hand held electric tool of power with the single phase series motor, it have safe and reliable, efficient is high, characteristics such as easy to operate, is widely used in the operation of every field.Traditional electric pick in use needs the workmen to exert pressure with hand could produce impulsive force; Body also will produce very big back seat impulsive force and be delivered on the operating grip when producing impulsive force, kick directly influences operating efficiency, therefore in handle end damping will be set; The tradition damping uses for a long time; Can make the elastic component wearing and tearing and lose elastic force, and drop easily, cause not having damping effect; General in addition gear-box is split type, processed complex, and required precision is high, and operation is also many; A certain step is made mistakes in the process of making, and just cancels, and has wasted material, has increased cost; The leakage of oil situation is very obvious, and inconvenient when installation process, and losing time fritters away energy; Original lining is an integrative-structure, usually with O RunddichtringO sealing, but the time grown, the leakage of oil situation is obvious.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this invention is to provide a kind of electric pick.
Another object of the present invention provides a kind of installation method of electric pick.
The technical scheme that the present invention adopts is:
A kind of electric pick comprises front end handle, rear end handle, gear-box and impact bar, and said rear end handle end is provided with damping; Said gear-box is structure as a whole; Once punch in the said gear-box and form clear opening, said gear-box inwall has the jump ring groove that can place jump ring, and said gear-box bottom is provided with seal; Said seal is provided with oil sealing a, and said gear-box bottom also is provided with reinforcement.
Said damping comprises that damping fixed mount and damping promote frame; Said damping fixed mount and damping promote to form left block rubber put area and right block rubber put area respectively between the frame; Block rubber and right side block rubber on the left of clamping has respectively in said left block rubber put area and the right block rubber put area; Said damping promotes to be provided with sliding axle between the frame; Said sliding axle two ends are passed left side block rubber and right side block rubber respectively, and said damping fixed mount two sides have the stroke groove that supplies sliding axle to slide.
Said impact bar is connected with impact block, and said impact block is through in the lining, and said lining is divided into lining body and following lining body for a minute body structure, said lining, is provided with oil sealing b in the said following lining body.
A kind of installation method of electric pick is pressed into the gear-box inwall to bearing a earlier, is pressed into bearing a to the electric pick bent axle then, presses reduction gearing then, overlaps upper bearing (metal) b again on electric pick bent axle top, and this a whole set of assembly is directly put into jump ring on the electric pick bent axle card, installation.
Advantage of the present invention is: gear-box adopts integrative-structure, and is easy to process, and it is also convenient to install, and prevents that oil from leaking, and reduced production cost; The gear-box bottom is provided with reinforcement, makes the bottom reach certain intensity; Lining is for dividing body structure, and lining is divided into lining body and following lining body, is provided with oil sealing b in the following lining body, has avoided the generation of leakage of oil situation; This damping good damping effect, sliding axle slides in the stroke groove, because the elastic force of left and right side block rubber has strengthened restoring force backward, reduces wear good damping effect; Installation method in the gear-box is simpler than original structure, and practicality is convenient, and closure is more reasonable.
