Description
Technical field
This utility model relates to a kind of eccentric stiffener, a kind of adjustable high accuracy eccentric stiffener.
Background technology
Bolt is the connector that mechanized equipment is important, but bolt often occurs under conditions of vibrations occurs in mechanized equipment
Loosen, therefore study the amplitude of vibrations significant to the safety in production of plant equipment with the relation of bolt looseness.Simultaneously
There is equipment component to need accurate eccentric adjustment amplitude, for this equipment component, do not have the height in the plant equipment that can apply temporarily
Precision bias amplitude regulation arrangement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of adjustable high accuracy eccentric stiffener, its degree of regulation
Height, and higher live load can be born, it is especially suitable for applying on the appliance arrangement needing accurate eccentric adjustment amplitude.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of adjustable high accuracy is eccentric
Mechanism, including adjustment bar, drive block and eccentric block, drive block is two pieces and carries reeded platy structure, and two boards shape structure is recessed
Groove is relatively fixed setting, and eccentric block is fixed in the groove of drive block, and adjustment bar is located on eccentric block, and adjustment bar is with eccentric
Contact surface between block is inclined-plane；
Drive block side is provided with adjusting screw rod, and adjusting screw rod is threadeded with drive block, and adjusting screw rod one end is stretched into and driven
Motion block and adjustment bar end thereof contacts；
Eccentric block one end is provided with standing screw, and standing screw is threadeded with eccentric block, and standing screw one end is stretched into partially
Heart block and adjustment bar one side contacts.
Preferably in scheme, one end that described adjustment bar does not contacts with adjusting screw rod passes drive block side, is passing
Drive block side be provided with leaf spring, leaf spring one end is fixed on drive block by the second screw.
Preferably in scheme, described drive block is away from being provided with end cap between one end of standing screw, and end cap passes through first
Screw is fixed with drive block one end.
Preferably in scheme, between described end cap and eccentric block, it is provided with spring.
This novel provided one adjustable high accuracy eccentric stiffener, by using said structure, has following useful
Effect:
(1) regulation of eccentric stiffener is realized by adjusting screw rod, it is achieved high-precision eccentric amplitude adjusted；
(2) make the end face of adjustment bar be close to adjusting screw rod by the elastic force of leaf spring, thus realize adjustment bar and follow regulation
Screw rod moves and moves；
(3) realize the regulation of eccentric stiffener by standing screw and fix, eccentric stiffener when standing screw unclamps, can be realized
Regulation, realize the fixing of eccentric stiffener after tightening.

Detailed description of the invention
In figure, a kind of adjustable high accuracy eccentric stiffener, including adjustment bar 1, drive block 2 and eccentric block 7, drive block 2
Being two pieces and carry reeded platy structure, two boards shape texture grooves is relatively fixed setting, and eccentric block 7 is fixed on drive block 2
In groove, adjustment bar 1 is located on eccentric block 7, and the contact surface between adjustment bar 1 and eccentric block 7 is inclined-plane；
Drive block 2 side is provided with adjusting screw rod 6, and adjusting screw rod 6 is threadeded with drive block 2, and adjusting screw rod 6 one end is stretched
Enter drive block 2 and adjustment bar 1 end thereof contacts；
Eccentric block 7 one end is provided with standing screw 8, and standing screw 8 is threadeded with eccentric block 7, and standing screw 8 one end is stretched
Enter eccentric block 7 and adjustment bar 1 one side contacts.
Preferably in scheme, one end that described adjustment bar 1 does not contacts with adjusting screw rod 6 passes drive block 2 side, is wearing
Drive block 2 side crossed is provided with leaf spring 10, and leaf spring 10 one end is fixed on drive block 2 by the second screw 9.Set plate
Spring, is used for realizing adjustment bar and follows adjusting screw rod and move and move, it is ensured that remain between adjustment bar with adjusting screw rod and contact.
Preferably in scheme, described drive block 2 is provided with end cap 4 between the one end away from standing screw 8, and end cap 4 passes through
First screw 3 is fixed with drive block 2 one end.Use said structure, it is achieved drive fast fixing.
Preferably in scheme, between described end cap 4 and eccentric block 7, it is provided with spring 5.
Part-circular periphery the drive block matched with adjusting screw rod etc. point 50 points, the pitch of adjusting screw rod is set to 0.5mm,
So scale of adjusting screw rod every turn, adjustment bar moves 0.5/50=0.01mm to the left or to the right, enter once to promote eccentric block to
Descend or move up, thus realizing the regulation of eccentric.
The degree of regulation of eccentric stiffener can be made to reach more than 0.01mm by changing the slope ratio of adjustment bar.
