Make input module far from output precision by transmission component, in narrow assembly space, by by bolt head
Sleeve 403 is sheathed on the bolt head of correspondingly-shaped, and it is precisely convenient to be clamped, and avoids bolt space interference nearby；Far from bolt
The position of head skirt 403 carries out driving driving lever 201 and rotates, and evades the operation near bolt to be tightened and needs larger operation
The technical issues of space, can be combined with prior arts driving equipments such as servo motors, applied widely.
Transmission component, driving gear and output gear, which are located at, states the inner cavity of shell structure, shell structure by corresponding component with
External world's isolation, avoids the fine particles such as the dust in outside air from being adhered to the engagement place of each gear, leads to each gear drive not
Stablize, influences the structural stability of fastener for bolt.
Upper cartridge body 101 and lower box body 102 are detachably connected to form shell structure, after being worn convenient for each accessory in shell more
It changes.
As another embodiment of the invention, transmission component is that gear-driven assembly, belt drive component and chain pass
One kind in dynamic component.
Using gear-driven assembly, by the engaged transmission between gear, the strength of gear teeth is big, and stable transmission is reliable, torsion
Lose small, precision height.
It using belt drive component, occupies little space, at low cost, belt can change length according to usage scenario, at low cost.
It using using belt drive component, occupies little space, chain can change length, at low cost, chain according to usage scenario
The structural strength of item is larger, and stable transmission is reliable.
As another embodiment of the invention, gear-driven assembly includes the first transmission that bearing is connected to mounting base 10
Bar 301 coaxial is fixed on the first drive link 301 and the first transmission gear 302, the bearing engaged with driving gear is connected to installation
Second drive link 303 of seat 10 and the second transmission gear 304 for being coaxially fixed on the second drive link 303, the second transmission gear 304
It is engaged respectively with the first transmission gear 302, output gear.
It is driven by Double-gear, relative to single gear drive, reduces the volume of gear-driven assembly, and can be according to reality
All gear-driven transmission ratios are adjusted flexibly in border assembly demand, and the bolt suitable for different demands tightens scene, further
Transfer assembly of the present invention can also be three or three or more gear drives.
As another embodiment of the invention, driving gear, the first transmission gear 302 height be more than the second driving cog
Wheel 304；Driving gear, the first transmission gear 302 height be more than output gear height.
When due to driving, driving gear moment starts, and driving force is larger, the height of driving gear and the first transmission gear 302
Degree is higher, and the Contact Transmission area of the two is larger, is driven through large contact area in power transmission process, prevents stress from crossing gear wheel
It is impaired；The height of second transmission gear 304 and output gear reduces, and reduces the piece volumes near bolt head sleeve 403, keeps away
Location conflicts cause assembly difficult when exempting to tighten assembly.
As another embodiment of the invention, driving gear, the first transmission gear 302, the second transmission gear 304 and defeated
The pressure angle for going out gear is 30 °.
Driving gear, the first transmission gear 302, the second transmission gear 304 and output gear pressure be 30 °, relative to
The gear that wirking pressure angle is 20 ° increases Gear Root width under the premise of not increasing fastener for bolt volume, to
Enhance the strength of gear teeth and toughness, gear torsion force is up to 50N.M, and far above the torsion that pressure angle is 20 ° of gears, transmission reaction is fast.
As another embodiment of the invention, driving gear, the first transmission gear 302, the second transmission gear 304 and defeated
Go out gear surface and is equipped with nitrocarburizing layer.
20GrMnVH can be used in each gear material.
Each gear surface forms nitrocarburizing layer by nitrogen-carbon cocementing process, to improve the hardness of gear surface, especially
It is the intensity between each gear at intermeshing, reduces abrasion, to prolong the service life, improve the stable transmission of each gear
Property.
As another embodiment of the invention, driving lever 201, the first drive link 301, the second drive link 303 and output
Bar 401 is connect with 10 bearing of mounting base respectively.
Driving lever 201, the first drive link 301, the second drive link 303 and 401 bearing of output rod are connected to mounting base 10, lead to
It crosses bearing realization to be rotatably connected, avoid due to driving lever 201, the first drive link 301, the second drive link 303 or output rod 401
Friction occurs with mounting base 10 to be damaged, while torsion being avoided to lose.
As another embodiment of the invention, driving lever 201, the first drive link 301, the second drive link 303 lead to respectively
Corresponding deep groove ball bearing 50 is crossed to connect with mounting base 10.
Driving lever 201, the first drive link 301, the second drive link 303 pass through corresponding deep groove ball bearing 50 and installation respectively
Seat 10 connects, and deep groove ball bearing 50 has self-aligning capability, in driving lever 201, the first drive link 301, the second drive link 303 and peace
When filling 2 '~10 ' offset of generation of seat 10, deep groove ball bearing 50 relatively rotates between still ensuring that institute's connecting component；In addition, zanjon
Ball bearing 50 is simple in structure, is easier to reach higher precision.
As another embodiment of the invention, output rod 401 is connect by thrust bearing 60 with mounting base 10.
Output rod 401 is limited by thrust bearing 60, and bolt head sleeve 403 is sheathed on when tightening bolt, and bolt pushes away
Power bearing 60 respectively generates bolt head sleeve 403 active force of opposite direction, and bolt head sleeve 403 is combined more with bolt
Add it is reliable and stable, transmission tighten accuracy height.
Further include clamp spring 70 as another embodiment of the invention, 401 other end of output rod runs through mounting base 10, card
Spring 70 is arranged the other end with output rod 401.
Output rod 401 is fixed on mounting base 10 by clamp spring 70, is convenient for the bolt head sleeve on output rod 401
It is replaced after 403 abrasions.
Bolt head sleeve 403 can be replaced according to the specification of different bolts.
As another embodiment of the invention, mounting base 10 is equipped with alloy steel bushing 80, steel alloy with output shaft junction
Set 80 is sheathed on output rod 401.
By the way that alloy steel bushing 80 is arranged, torsion is caused to lose with the friction of mounting base 10 when reducing output shaft rotation, through surveying
Examination, torsion loss are less than 5%.
As shown in figure 4, the still another embodiment as the present invention, active drive part 202 is one end and driving lever 201
First drive rod of one end connection；Output driving part 402 is the second drive rod that one end is connect with 401 other end of output rod；The
The radius of gyration of the one drive rod other end is equal with the radius of gyration of the second drive rod other end, the first drive rod other end and
The two drive rod other ends are connected by connector.
The free end of the free end and the second drive rod of the first drive rod is connected by connector, driving lever 201 drives the
When one drive rod rotates, the second drive rod is driven by the connector of rigidity, to drive output rod 401 to rotate, to spiral shell
Bolt is tightened, and connecting rod can be used in connector, is occupied little space, and this connection structure avoids the position of each component when rotation from doing
It relates to, it is simple in structure.
The above embodiment is only the certain preferred embodiments of the present invention, cannot limit the model protected of the present invention with this
It encloses, the variation and replacement of any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to the present invention
Range claimed.
