Embodiment 2
The present embodiment provides a kind of methods that slider of bender depth of parallelism is adjusted, electronic flat using the bending machine of embodiment 1
Weighing apparatus regulating device is adjusted, the specific steps are as follows:
1. carrying out equipment assembling according to the structure in embodiment 1, assembling steps are as follows:
First the inclination of balance shaft 2 is placed between two wallboards 1, is then inserted into one end in the mounting hole of wallboard 1, and from
The outside of wallboard 1 is reached on the inside of wallboard 1, is then inserted into the other end of balance shaft 2 in the mounting hole of another wallboard 1;So
Balance shaft 2 is sling with driving afterwards, 2 axis of balance shaft is aligned with 1 upper installing hole center of wallboard, self-aligning roller bearing is knocked in
It does not install in the mounting hole of wallboard 1 of balance adjustment mechanism side, and makes the inner ring of 2 end of balance shaft insertion self-aligning roller bearing
Kong Zhong installs end cap 16, blending bolt fastening on the outside of wallboard 1;A self-aligning roller bearing is taken again, is packed into the inclined of eccentric bushing 9
In heart hole 902, first wear-resistant sleeve 13 is knocked in 1 upper installing hole of wallboard, then loads onto eccentric bushing 9, and makes the end of balance shaft 2
It is inserted into the inner ring hole of self-aligning roller bearing, puts on retaining ring 14 and limited with 15 clamping of eccentric bushing circlip and fixed;Bearing block 5 is led to
It crosses pin shaft 4 to be installed in the adjustment seat 3 being fixed on wallboard 1, and is packed into lead screw 6 and decelerating motor 12;By feed screw nut 7 and support
Plate 8 connects, and is then installed to supporting plate 8 on eccentric bushing 9 by key, while dial 11 being installed, and adjusts 8 position of supporting plate,
Lead screw 6 rotates, and makes 7 sets of feed screw nut on lead screw 6, and adjusts that supporting plate 8 is horizontal, i.e., pointer is directed toward dial 11 on eccentric bushing 9
Zero graduation;Then, travel switch 10 is installed on wallboard 1;Finally, the rocking bar at 2 both ends of balance shaft is connect with sliding block, it is complete
At assembly.After being completed, each component connection reliability is checked, guarantee that equipment state is normal.
2. measuring height of the both ends of sliding block lower end surface apart from workbench, and calculate difference in height;
3., detailed process are as follows: decelerating motor 12 open parallel with workbench by balance adjustment mechanism adjusting slider lower end surface
Dynamic, driving lead screw 6 rotates, and feed screw nut 7 moves on lead screw 6 and supporting plate 8 is pushed to rotate, so that supporting plate 8 drives 9 turns of eccentric bushing
Dynamic, adjustment 2 one end of balance shaft is raised and lowered, so that one end that sliding block is located at eccentric bushing 9 is raised and lowered, when under sliding block
When end face is parallel with workbench, decelerating motor 12 stops working, and completes balance adjustment operation.In this step, eccentric bushing 9 was rotated
Adjusting height in journey in vertical direction is h, thenWherein, S is eccentricity, and χ is lead screw spiral shell
The distance that mother 7 moves on lead screw 6, R are the radius of gyration of supporting plate 8.Adjusting height can be calculated by this formula, thus side
Just corresponding scale value is marked on dial 11;In addition, can control the maximum value of height adjustment by controlling eccentricity S
And minimum value, the ratio of the radius of gyration R of distance χ and supporting plate 8 that feed screw nut 7 moves on lead screw 6 can control 6 revolving speed of lead screw
The ratio between the angular speed rotated with eccentric bushing 9, so as to realize high-precision adjusting.In the present embodiment, S=4mm takes the π of χ=45
Mm, R=180mm, thenThat is, lead screw spiral shell
The mobile 45 π mm distances on lead screw 6 of mother 7, eccentric bushing 9 are 2mm in the adjusting height of vertical direction, i.e., one end of sliding block rise or
Decline 2mm.
Usually when in use, when needing to be adjusted, pass through the quarter on dial 11 indicated by pointer on eccentric bushing 9
Degree can determine the distance that sliding block rises or falls.
Step 3. in, when supporting plate 8 is rotated clockwise or counterclockwise more than set angle, supporting plate 8 and travel switch 10
Contact, travel switch 10 generate electric signal and are sent to control system, and control system control decelerating motor 12 stops working, thus
So that supporting plate 8 stops operating, avoids the moving distance on lead screw 6 of feed screw nut 7 from going beyond the scope, play the role of safeguard protection.
Example of the present invention is only that preferred embodiments of the present invention will be described, not to present inventive concept and
Range is defined, and under the premise of not departing from design philosophy of the present invention, this field engineers and technicians are to technology of the invention
The various changes and improvements that scheme is made should all fall into protection scope of the present invention.
