Description
Technical field
The present invention relates to sheetmetal manufacture field, especially relate to a kind of dynamic structure of percussion drill.
Background technique
In existing technology, percussion drill relies on and rotates and impact work.Single impact is very slight, but per minute 40, the frequency of impact of more than 000 time can produce continuous print power.Can be used for natural stone or concrete.Adjusting knob is had at drill bushing place, adjustable common hand drill and percussion drill two kinds of modes during percussion drill work.But percussion drill is the gear in utilizing on axle beats to realize impact effect mutually, but impact force is far away not as good as electric hammer.It is not suitable for boring reinforced concrete.Existing percussion drill also has complex structure, part processing difficulties, the technical problems such as adjustment is wasted time and energy, inefficiency simultaneously.
Summary of the invention
The object of this invention is to provide the dynamic structure of a kind of percussion drill that a kind of structure is simple, simple to operate, manufacturing efficiency is high, be especially suitable for sheetmetal processing.
Technological scheme of the present invention is:
A dynamic structure for percussion drill, comprises shell, clutch shaft bearing, dwang, the first bevel gear, weight, movement weight rod, rotating shaft, the second bevel gear, power lever and the second bearing;
Described shell is regular hexahedron, two faces that described shell is relative are respectively arranged with described clutch shaft bearing, the second bearing, described drive link is rotationally connected by described clutch shaft bearing and described shell, described power lever is rotationally connected by described second bearing and described shell, one end that described power lever and described drive link are positioned at described enclosure is all fixedly connected with described first bevel gear
On two opposing sides of described shell and described power lever axis parallel, be respectively arranged with described rotating shaft, described rotating shaft and described shell are rotationally connected, described rotating shaft is fixedly installed described movement weight rod, described movement weight rod is mutually vertical with described rotating shaft, the other one end be connected with described rotating shaft at described movement weight rod is fixedly installed described weight, and described second bevel gear is fixedly connected with described rotating shaft one end away from described shell;
Described first bevel gear, the second bevel gear are connected by gear.
Further, the partial fixing that described dwang is positioned at described housing outward end is provided with described drill jig, is convenient for changing drill bit, because drill bit belongs to easily-consumed products, in use, easily produces loss, now just needs to change in time, meets requirement of engineering.
Further, described second bearing, power lever, the first bevel gear, clutch shaft bearing are positioned on same axle center, when assembly moves in a circle around Pivot Point Center at a high speed, eccentric structure can make device make unnecessary vibrations, and has influence on the stability of device entirety.
Further, described weight material comprises cast iron materials, and this material is durable, and cheap for manufacturing cost, can reduce overall cost for this device.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, this device in use has following features, owing to adopting the vibration mode of eccentric hammer, this kind of structure quake is effective and structure is simple for ease of maintenaince, in practical work process, has very large actual use value, in boring procedure, add vibrations simultaneously, also drilling efficiency can be made greatly to improve, and this device also has following features simultaneously, uses convenient; Have structure simple, easy to maintenance, processing cost is low, manufacturing efficiency advantages of higher.
Accompanying drawing explanation

Embodiment
As shown in Figure 1, the present invention includes shell 1, clutch shaft bearing 2, drive link 4, first bevel gear 5, weight 6, movement weight rod 7, rotating shaft 8, second bevel gear 9, power lever 10 and the second bearing 11;
Described shell 1 is regular hexahedron, two faces that described shell 1 is relative are respectively arranged with described clutch shaft bearing 2, second bearing 11, described drive link 4 is rotationally connected with described shell 1 by described clutch shaft bearing 2, described power lever 10 is rotationally connected with described shell 1 by described second bearing 11, one end that described power lever 10 and described drive link 4 are positioned at described shell 1 inside is all fixedly connected with described first bevel gear 5, the partial fixing that described drive link 4 is positioned at described shell 1 outer end is provided with described drill jig 3, described second bearing 11, power lever 10, first bevel gear 5, clutch shaft bearing 2 is positioned on same axle center,
Described shell 1 is with on two opposing sides of described power lever 10 axis parallel, be respectively arranged with described rotating shaft 8, described rotating shaft 8 is rotationally connected with described shell 1, described rotating shaft 8 is fixedly installed described movement weight rod 7, described movement weight rod 7 is mutually vertical with described rotating shaft 8, the other one end be connected with described rotating shaft 8 at described movement weight rod 7 is fixedly installed described weight 6, described weight 6 material comprises cast iron materials, and described second bevel gear 9 is fixedly connected with described rotating shaft 8 one end away from described shell 1;
Described first bevel gear 5, second bevel gear 9 is connected by gear.
The working procedure of this example: first driven by motor power lever 10 starts to rotate, then the first bevel gear 5, drill jig 3 starts to rotate, first bevel gear 5 can rotate at the second bevel gear 9 simultaneously thereupon, now drill bit also can be started working under the drive of drill jig 3, meanwhile, weight can start to move in a circle under the drive of rotating shaft 8, now will produce larger vibrations, this vibrations are conducive to the quick jewel hole to metope, and when the dust of body of wall inside in boring procedure also can along with outside vibrations tap hole, so more be conducive to penetration rate to accelerate.
