Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art's every other embodiment obtained belong to what the present invention protected
Range.
Embodiment
Be a kind of tightening machine export head mechanism provided in an embodiment of the present invention referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, as Fig. 1,
Shown in Fig. 2, Fig. 3, Fig. 4, which includes shell 1；
Drive sprocket 2, the drive sprocket 2 with the shell 1 is rotatable is connected, one end of the drive sprocket 2 for realizing
It is connected with the output shaft 7 of tightening machine；
Driven sprocket 3, the driven sprocket 3 with the shell 1 is rotatable is connected, one end connection of the driven sprocket 3 is useful
In the sleeve 8 that realization is connected with the nut of bolt；
Wherein, the axis of the drive sprocket 2 is parallel with the axis of the driven sprocket 3, the drive sprocket 2 with it is described driven
Sprocket wheel 3 is connected by ring chain 4.
Further, the drive sprocket 2 and the driven sprocket 3 pass through bearing 5 and bearing block 6 and the shell respectively
Body 1 realizes rotatable be connected.The bearing 5 is needle bearing.
Further, the drive sprocket 2 is realized by splined member and is connected with the output shaft 7 of the tightening machine.It is described
Splined member includes spline and spline baffle.The splined member includes spline and screw baffle plate.The shell is by upper casing
Body and lower case are put together.
The mechanism includes drive sprocket, driven sprocket, chain, shell (upper housing, lower case), needle bearing, bearing block.
The drive sprocket provides power, and drive sprocket is combined in the form of spline with output shaft, and is fixed with spline baffle or screw,
Part as sprocket wheel transmission；The driven wheel refers to the sprocket wheel that chain driven, refers to the sprocket wheel being passively driven.The chain will
The movement of drive sprocket with special tooth profile and power are transmitted to a kind of kind of drive of the driven sprocket with special tooth profile；
The shell is used to install the shell structure of chain-drive mechanism and its attachment；The needle bearing is the Roller Shaft with cylindrical roller
It holds, its opposite diameter, roller was not only thin but also long, and bearing load-taking capacity still with higher, radial structure is compact, internal diameter ruler
When very little and load-carrying ability is identical as other types of bearings, gear can be covered and be unable to reach minimum outer diameter and torque, especially suitable for
The supporting structure of the size-constrained system of radially installed；The bearing block is for spring bearing, the outer ring of fixing bearing, Jin Jinrang
Inner ring rotation, outer ring remains stationary, is consistent always with the direction of transmission and keeps balancing.Advantage is compared with conventional gear
Torque is big, efficiency value is high under wide adaptation range (space is not achieved in conventional gear structure), identical appearance dimensional conditions tightens precision
Also it can reach the requirement of gear.
When in use, drive sprocket realizes rotation, drive sprocket rotation under the driving of the output shaft of tightening machine for the mechanism
When rotated by chain-driving driven sprocket, driven sprocket connection sleeve be set on the nut of bolt, may be implemented to spiral shell
Bolt tightens process.The mechanism replaces gear transmission mode in the prior art by the way of sprocket wheel chain transmission, can make
The overall dimensions of the export head mechanism are smaller, while the shell of the mechanism can tighten position and determine that its length, shell length are got over
Length may be implemented to tighten the bolt of distal end.It only needs to use the longer chain of length by drive chain when shell lengthens simultaneously
Wheel is connected with driven sprocket, not but not the diameter of increase export head, while will not have in cost of manufacture excessive
Increase.And gear-driven mode is used in the prior art, since gear is not suitable for the excessive quantity of setting, if to lengthen defeated
The length lifted one's head has to also will increase export head simultaneously although length can increase using the bigger gear of diameter
Diameter use it can not in the small spaces such as similar automobile axle.
Mechanism provided by the present application, it is simple and reasonable reliable, it designs and simplifies installation and repairing conveniently.Precision is high, and structure is tight
It gathers securely, saves the installation space of equipment.Injury can be protected the products from when tightening.Increasing the same of export head contact range
When, processing and operating cost can also be saved, and guarantee to tighten precision, be worth promoting the use of a large area.
