Abstract
The utility model discloses a high accuracy electric hammer cylinder ram device belongs to electric tool technical field. The utility model discloses a ram and ram cover, ram cover are worn to adorn in electric hammer frame through -hole, and the drill bit afterbody is connected with ram cover front end, are equipped with at least one gas pocket on the lateral wall of ram cover front end, set up the filter screen in the gas pocket, the ram cover be big, the middle little form in both ends. The utility model discloses set up the gas pocket with the front end of ram cover, set up the filter screen in the gas pocket, can prevent that the grieshoch from getting into the frame inner chamber, when the ram antedisplacement, plug up the gas pocket at the ram front end, make to form the one deck sealing layer between ram and the ram cover, because atmospheric pressure withstands the ram, the ram is the antedisplacement no longer to can protect the ram not receive wearing and tearing, improve the life of electric hammer, set the ram cover to both ends big, middle little form, can reduce the friction of ram, improve the work efficiency of ram.
Description
Technical field
The utility model belongs to electric tool technical field, especially relevant with a kind of high accuracy air cylinder of electric hammer percussion hammer device.
Background technology
Along with electric tool uses constantly universal, market demand constantly rises, China's electric tool was also in growth at full speed in recent years, but electric tool is of a great variety, use amount mostly is angle grinding machine and electric hammer most, and angle grinding machine can realize production domesticization completely in China, but some parts of electric hammer still need to rely on import, high expensive, adds purchase cost.Existing air cylinder of electric hammer percussion hammer device comprises percussion hammer, percussion hammer cover, and percussion hammer moves in percussion hammer cover, and the promotion being subject to cylinder pivoted housing due to percussion hammer makes percussion hammer move forward, and percussion hammer cover front end face inner chamber receives the shock of percussion hammer unavoidably and causes percussion hammer cover impaired.Therefore applicant has researched and developed a kind of precision electric hammer air cylinder of electric hammer percussion hammer device, is intended to improve the defects such as the domestic cylinder mass of existing air cylinder of electric hammer is not high, chip precision is low.
Utility model content
For the problems referred to above, the utility model patent provides a kind of high accuracy air cylinder of electric hammer percussion hammer device, and the utility model solves the defects such as the domestic cylinder mass of existing air cylinder of electric hammer is not high, chip precision is low.
For this reason, the utility model is by the following technical solutions: high accuracy air cylinder of electric hammer percussion hammer device, comprise percussion hammer and percussion hammer cover, percussion hammer cover is threaded onto in electric hammer support through hole, drill bit afterbody and percussion hammer overlap front end and are connected, percussion hammer is placed in percussion hammer cover inner chamber and slip, it is characterized in that, the sidewall of described percussion hammer cover front end is provided with at least one pore, in pore, screen pack is set, described percussion hammer cover is in large, the middle little shape in two ends, and the rear and front end of percussion hammer cover and percussion hammer overlap sidewall and fit, thus can reduce the friction of percussion hammer when the slippage of percussion hammer cover.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
Described percussion hammer front end is provided with the cannelure of multiple indent, arranges annular ring in cannelure
Three swords on described drill bit are dissymmetrical structure.
The periphery of described percussion hammer cover front end is coated by spring, thus can reduce percussion hammer and operationally reduce vibrations.
Described pore is two.
Use the utility model can reach following beneficial effect: the front end that percussion hammer overlaps is arranged pore by the utility model; in pore, screen pack is set; can prevent grieshoch from entering support inner chamber; when percussion hammer moves forward; in percussion hammer front end, pore is blocked; make percussion hammer and percussion hammer overlap between form one deck sealant; because air pressure withstands percussion hammer; percussion hammer no longer moves forward; thus percussion hammer can be protected not frayed, improve the service life of electric hammer, percussion hammer cover is arranged to large, the middle little shape in two ends; the friction of percussion hammer can be reduced, improve the operating efficiency of percussion hammer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Embodiment: as shown in Figure 1, the utility model comprises percussion hammer 3 and percussion hammer cover 1, percussion hammer cover 1 is threaded onto in electric hammer support through hole, drill bit 6 afterbody and percussion hammer overlap 1 front end and are connected, and percussion hammer 3 is placed in percussion hammer and overlaps 1 inner chamber and slip, and the sidewall that percussion hammer overlaps 1 front end is provided with at least one pore 2, in pore 2, screen pack is set, described percussion hammer cover 1 is in large, the middle little shape in two ends, and the rear and front end of percussion hammer cover 1 and percussion hammer overlap 1 sidewall and fit, thus can reduce the friction of percussion hammer 3 when percussion hammer overlaps 1 slippage.
Percussion hammer 3 front end is provided with the cannelure of multiple indent, arranges annular ring 4 in cannelure.
As preferably, three swords on drill bit 6 are dissymmetrical structure.
Further, the periphery that percussion hammer overlaps 1 front end is coated by spring 5, thus can reduce percussion hammer 3 and operationally reduce vibrations.
Preferably, pore 2 is two.
The front end that percussion hammer overlaps is arranged pore by the utility model, in pore, arrange screen pack, can prevent grieshoch from entering support inner chamber; when percussion hammer moves forward; in percussion hammer front end, pore is blocked, make percussion hammer and percussion hammer overlap between form one deck sealant, because air pressure withstands percussion hammer; percussion hammer no longer moves forward; thus percussion hammer can be protected not frayed, improve the service life of electric hammer, percussion hammer cover is arranged to large, the middle little shape in two ends; the friction of percussion hammer can be reduced, improve the operating efficiency of percussion hammer.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
