Abstract
The invention discloses a wrench which comprises a power source, a driving wheel, a driven wheel, a clutch and a flywheel assembly, wherein the driving wheel is connected with the power source; the driven wheel is connected with the driving wheel; the clutch is connected with the driven wheel; the flywheel assembly is connected with the clutch; the flywheel assembly comprises a flywheel, and upper and lower impact blocks rotatably connected with the flywheel; the upper impact block and the lower impact block are connected through a tension spring; a pressure spring and a pressure ball are arranged between the impact blocks and the flywheel; an impact block positioning bolt is arranged on the flywheel; a main shaft is arranged in the center position of the flywheel assembly through a bearing; and a bulge is formed in the main shaft. Energy is accumulated continuously through rotating a motor at a high speed to drive the flywheel to rotate at a high speed, and after the energy is released instantaneously, the bulge on the main shaft is impacted by the impact blocks, and the energy is transmitted to a bolt or a nut through the main shaft to reach a dismounting working condition.
Description
Technical field:
The present invention relates to a kind of hardware ﹠ tools, particularly a kind of spanner.
Background technology:
Spanner is divided into manual wrench, electric wrench, pneumatic impact spanner etc.Manual wrench: come work with the principle of lever, handle more long torsion is just more big, is divided into manual mechanical wrench again, and the displacement by gear reaches more labour-saving effect of bigger torsion, but service speed can slow down greatly.Pneumatic impact spanner: being called the wind big gun again, is a kind of of pneumatic tools, and it has saved the strength of manpower, uses compressed air drive wind motor and drives main shaft, to reach the effect of assembling-disassembling bolt or nut.But this instrument also will pass through air compressor except wanting electricity consumption, uses inconvenience, and energy loss is very big, but torsion is big relatively, safety is more reliable.Electric wrench: traditional electric wrench can be divided into direct current and exchange, and the spanner moment of torsion of direct current is very little, and electric current is but very big.Reason is that this structure is come work by the mode of the displacement of gear, and bigger bolt or nut will just can be finished the work with the AC power of 380V.The use energy consumption of this product is very big, and own wt is also very heavy, and the complex structure cost is not only high but also take very much electric energy.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of spanner of brand-new type, and the technical scheme that it adopts is: a kind of spanner: comprise power source; The driving wheel that connects with power source; The driven pulley that connects with driving wheel; The clutch that connects with driven pulley; The fly wheel assembly that connects with clutch; Fly wheel assembly comprises flywheel, turns the impact block up and down that connects with flywheel, and impact block links by extension spring up and down, also is provided with stage clip and pressure ball between described impact block and the flywheel, also is provided with the impact block bolt on the described flywheel; The fly wheel assembly center is provided with a main shaft by bearing, and main shaft is provided with projection.
The present invention further technical characterictic is:
Described driven pulley and clutch are monolithic construction.
Described power source is direct current generator, alternating current generator or wind motor.
Described clutch comprises support and friction plate up and down, and friction plate links by extension spring up and down.
The invention has the beneficial effects as follows:
The present invention constantly gathers strength by the high-speed rotation drive flywheel high-speed rotation of motor, and the abrupt release energy is delivered on bolt or the nut by main shaft, to reach the working condition of dismounting by the projection on the impact block bump main shaft.The present invention adopts clutch, the reaction force that produces during the huge impact of having dissolved that spanner produces in operation, and the motor that not only reduced current protection, and do not have the counter-force safer when using.The characteristics of this structure are, available direct current, and energy saving, easy to operate, safe and reliable, relative weight is light, easy to carry, practicality advantage such as cost is low.From use value: because the present invention has adopted the version of clutch; make motor not produce stall; the big electric current that produces when avoiding motor rotation blockage; thereby reach the protection motor effect of energy savings again simultaneously; and the instability distortion that does not in use cause because of reaction force, safer comfortable to the user.

Fig. 2 is the structural representation of clutch;
Fig. 3 is the structure cutaway view of fly wheel assembly;
Fig. 4 is the cutaway view of A-A direction among Fig. 1.
The specific embodiment:
The present invention will be further described to engage accompanying drawing below:
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of spanner: comprise power source 1; The driving wheel 2 that connects with power source 1; The driven pulley 3 that connects with driving wheel 2; The clutch 4 that connects with driven pulley 3; The fly wheel assembly 5 that connects with clutch 4; Fly wheel assembly 5 comprises flywheel 501, turns the impact blocks up and down 502 that connect with flywheel 501, impact block 502 links by replying extension spring 503 up and down, also be provided with stage clip 504 and pressure ball 505 between described impact block 502 and the flywheel 501, also be provided with impact block bolt 506 on the described flywheel 501; Fly wheel assembly 5 centers are provided with a main shaft 6 by bearing, and main shaft 6 is provided with projection 601.
In the present embodiment, described driven pulley 3 and clutch 4 are monolithic construction, and described power source 1 is direct current generator, also can be alternating current generator or wind motor.
As depicted in figs. 1 and 2, clutch described in the present embodiment 4 comprises support 401 and friction plate 402 up and down, and friction plate 402 links by reset tension spring 403 up and down.
In actual applications, energising rear motor 1 runs up, drive driving wheel 2 and driven transmission wheel 3 and clutch 4, the clutch sassafras sheet 402 that rubs outwards flies out, and drive fly wheel assembly 5, in the present embodiment, flywheel 501 in the fly wheel assembly 5 and impact block 502 are by 507 rotatable connections of two Fixed latches, and also be provided with stage clip 504 and pressure ball 505 between impact block 502 and the flywheel 501, flywheel 501 high-speed rotation under clutch 4 drives constantly gathers strength, the abrupt release energy is overcome the resistance of the answer extension spring 503 of 502 of the pressure ball 505 that is installed on the flywheel 501 and two impact blocks by the heavily end of impact block 502, impact block 502 is heavily held and is outwards flown out, the light end of impact block 502 impinges upon on the projection 601 of main shaft 6, is delivered on bolt or the nut by main shaft 6, to reach the working condition of dismounting.As shown in Figure 4, in the moment of impact block 502 and main shaft 6 effects, the friction plate 402 of impact block 502 and clutch is replied under the effect of replying extension spring 503 and reset tension spring 403, and impact block 502 is subjected to the location of bolt 506, get back to original position, cycle operation next time begins again.
Though described the specific embodiment herein, coverage of the present invention is not limited thereto.On the contrary, all technical schemes are within the scope of the claims contained all and fall in fact on literal or under the instruction in equivalents in the present invention.Protection scope of the present invention is as the criterion with claims.
