Rod member for grid docks length automaton
Technical field
Length control device is docked the present invention relates to a kind of rod member, particularly rod member for grid docking length automatically controls dress
Put, it is applied to grid structure bar and docks automatically controlling for length.
Background technology
The safety and stability of grid structure, is heavily dependent on the quality of rack component, wherein rod member for grid
Quality be an important link in grid structure again.How to ensure rod member welding quality and welding after length theory by mistake
In the scope of difference, crucial factor, further has influence on the security and durability of grid structure in being produced as rack.Mesh
Before, most domestic rack manufacturing enterprise is positioned by easy frock, and frock is adjusted according to rod length size,
Rod member butting tooling Adjustment precision depends entirely on the measurement accuracy of box chi, and two location-plate fastening bolts tighten journey
Degree, if running into special-shaped reticulated shell, the dimensions of rod member is more, and the length difference of every kind of rod member only has 2mm sometimes, if by
Former this extensive positioning method of butt-joint process is it is difficult to ensure that the accuracy of rod length, causes rod length overproof and unqualified
The appearance of product, eventually affects the security and durability of product quality and grid structure.In addition, the original butt-joint process pair of rod member
Release and the bolt of screwed in place plate that each size adjusting of rod member will be repeatedly, make operating personnel labor intensity increase and
Production non-cutting time is longer, low production efficiency.
The content of the invention
Length automaton is docked it is an object of the invention to provide a kind of rod member for grid, it can overcome existing skill
The deficiency of art, length is automatically controlled when rod member for grid docking can be achieved, the effective joint quality for improving rod member for grid and life
Efficiency is produced, so as to improve the overall dimensional accuracy of rack installation.
Its solution is:Rod member for grid docks length automaton by detent mechanism numerical control system and positioning
Mechanism two parts are constituted.Control panel is provided with switch board casing, in origin length input window is distributed with control panel
Mouth, weld length input window, equipment origin button, forward key, Reverse keys, feeding button, and in switch board casing
The step actuator for being provided with controller and being electrically connected with the controller, constitutes detent mechanism numerical control system.The detent mechanism
Numerical control system is electrically connected by cable with the stepper motor of detent mechanism.By the control of detent mechanism numerical control system
Device launches pulse to step actuator, and the stepper motor rotation of step actuator driving detent mechanism forces the work of detent mechanism
Dynamic align member translation, is finally reached being accurately positioned for rod member for grid length, the automatic control of length when realizing rod member for grid docking
System.
Stepper motor and stationary positioned plate that the detent mechanism is connected by frame and thereon, the rolling being connected with stepper motor
Ballscrew, the activity orientation component being movably connected on ball-screw is constituted.
The activity orientation component is by movable positioning plate, and it is connected in frame by the way that connected mobile base is same
Guide rail is flexibly connected, and mobile base is flexibly connected further through connecting plate and nut and constituted with ball-screw.
The present invention uses above-mentioned technical proposal, and according to the length dimension of rod member for grid, pulse is launched to step by controller
Enter driver, the rotation of step actuator Driving Stepping Motor, and drive activity orientation component to be translated along the guide rail in frame, finally
Being accurately positioned for rod member for grid length is reached, length automatically controls when realizing rod member for grid docking.Due to rod member for grid length
Registration, the error in length of rod member for grid is controlled within ± 0.3mm, the error in length value of the rod member for grid is than country
Error amount as defined in standard reduces 3 times, so, the overall accumulated error of rack can also reduce 3 times simultaneously, and this is for its length
Longer and complex-shaped rack can be highly beneficial.Because length is automatically controlled when realizing rod member for grid docking, and structure letter
It is single, easy to operate, it can save for 30% non-cutting time in operation, production efficiency can be effectively improved.
Brief description of the drawings
Fig. 1 is the structural representation that rod member for grid docks length automaton.
Fig. 2 is detent mechanism numerical control system schematic diagram in Fig. 1.
Embodiment
The embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
Fig. 1 is into Fig. 2, and rod member for grid docks length automaton by detent mechanism numerical control system and localization machine
Structure two parts are constituted.Control panel 18 is provided with switch board casing 17, it is defeated in origin length is distributed with control panel 18
Enter window 1, weld length input window 2, equipment origin button 3, forward key 4, Reverse keys 5, feeding button 6, and in control
Controller 19, and the first step actuator 20 electrically connected with controller 19 and the second stepper drive are provided with cabinet casing 17 processed
Device 21, constitutes detent mechanism numerical control system.The detent mechanism is by frame 14 and the stepping connected thereon electromechanics 11 and admittedly
Determine location-plate 7, the ball-screw 15 being connected with stepper motor 11 is movably connected in the activity orientation component structure on ball-screw 15
Into.And activity orientation component is by movable positioning plate 8, the movable positioning plate 8 is by connected mobile base 9 with being connected to machine
Guide rail 16 on frame 14 is slidably connected, and mobile base 9 is fixedly connected further through connecting plate 10 with nut 13, nut 13 and ball wire
Thick stick 15 is threadedly coupled and constituted.The detent mechanism numerical control system passes through cable 12 and the stepper motor 11 of detent mechanism
Electrical connection.Launch pulse by the controller 19 of detent mechanism numerical control system to drive to the first step actuator 20 and the second stepping
Dynamic device 21, and drive the stepper motor 11 of detent mechanism to rotate, force the activity orientation component of detent mechanism to be translated along guide rail 16,
Reach rod member for grid docking length to be accurately positioned, length automatically controls when realizing rod member for grid docking.
During work, the value of rod length by the gross to be processed is averaged as origin length first, this length is inputted
Into origin length window 1, it is origin length to adjust the distance between movable positioning plate 8 and stationary positioned plate 7 by origin button,
Now, the first step actuator 20 and the second step actuator 21 are given in the transmitting of controller 19 pulse and Driving Stepping Motor 11 revolves
Turn, stepper motor 11 drives ball-screw 15 to rotate, ball-screw 15 drives movable positioning plate 8 by nut 13 and connecting plate 10
Longitudinally move to the origin extension position of rod member for grid.Then the welding of rod member for grid is inputted in weld length input window 2 again
Length, if this length is more than origin length, by Reverse keys 5, if this length is less than origin length, is pressed by advance
Key 4, according still further to the above method, you can realize being accurately positioned for rod member for grid length.If rod size scope is larger, it will can consolidate
Determine location-plate 7 and required suitable distance is moved to along frame 14, then origin position is adjusted to by detent mechanism numerical control system
Put, repeat above-mentioned operation.It is fine setting button to feed button, such as needs trim lengths, can be finely tuned with this key.
