Description

Intelligent gang drill processing production line

Technical Field

The invention relates to the technical field of plate processing machinery, in particular to an intelligent gang drill processing production line.

Background

With the popularization of industry 4.0, the production mode of furniture factories is changed, more and more large furniture factories use automatic production lines, and the production of plate-type furniture cannot leave drilling equipment which is indispensable like the production line for producing plate elements in batches.

In the process of automatic online production, in order to obtain various production requirements, a series of processing and manufacturing processes such as conveying, polishing, drilling and the like are performed on a plate, conveying and drilling for the plate are generally performed by adopting a conveying table and drilling equipment, and the drilling equipment is used for drilling the plate by the arranged gang drilling device; however, the existing conveying table usually adopts a driving mechanism, and the conveying speeds of the front section and the rear section of the conveying table are the same; thus, the drilling equipment cannot be well jointed, and the reject ratio of the product is increased;

and the traditional wire drilling equipment is always a short plate of the whole wire, the efficiency is far lower than that of edge sealing equipment, and the productivity of the whole wire is reduced. The power of the traditional gang drill drilling is carried out in a cylinder driving mode, the driving mode has the defects of inaccurate displacement size control, long machine adjusting time and incapability of realizing flexible and controllable stroke, the efficiency is influenced, and the structural arrangement of a displacement driving mechanism is unreasonable, so that the overall structural layout is influenced; furthermore, the production line can continuously process without stop, which puts higher demands on the reliability of the precision of the equipment, and if the drill deviates from the target position in the drilling process, the plate pieces are scrapped in batches, and the loss is large. Drilling equipment drills to panel through the gang drill device that sets up, the brill row of its gang drill device need carry out the translation and remove, for this reason, need set up the translation of translation drive screw in order to guarantee the gang drill, the in-process that the translation drive shaft was punched in batches, though there is the air lock nevertheless still to take place the skew of angle for a long time, but present gang drill device does not possess the angle monitoring structure that deflects, can't carry out dynamic monitoring in real time to drive screw's angle deflection, lead to the condition that the drive screw angle deflection still continues to process the plate probably to appear, cause the batch of plate to scrap.

Still, in the in-process of automatic line production, the plate that comes out from the limit machine conveys drilling equipment through carrying the platform and processes, and a problem can appear at this moment, and the plate that flows through carrying the platform can't judge the direction of processing of the equipment that length and width direction corresponds, and this can appear two consequences, and first probably causes the plate to punch the mistake in batches, and the second can appear the unable equipment that flows through of panel. In order to reduce the failure rate of the automatic wiring equipment, whether the plate feeding direction is correct or not is acquired in advance before the plate enters the equipment, and foreign wiring equipment generally adopts laser measurement, but the cost is very high and is influenced by factors such as floating and sinking.

Therefore, a new technology needs to be developed to solve the above problems.

The other end of the second lead screw 401 is connected to a plane bearing (in this embodiment, the plane bearing is defined as a second bearing 408, which is described below as the second bearing 408), and a lock nut 409, the second bearing 408 is fixed on the copper base 406, and the other end of the second lead screw 401 passes through the second bearing 408 through the copper base 406; the locking nut 409 is locked at the other end of the second lead screw 401 and is positioned outside the second bearing 408; the locking nut 409 is provided with a through hole 4091, one end of the second lead screw 401 penetrates through the through hole 4091, and the axis of the through hole 4091 is overlapped with the axis of the second lead screw 401, so that the monitoring hole 5013 and the through hole 4091 are arranged coaxially.

There are two second lead screws 401, and accordingly, there are two encoders 407, monitoring holes 5013, second bearings 408, and lock nuts 409. And, an air lock 6 is arranged on the copper substrate 406.

In summary, the design of the invention is mainly characterized in that the two-section type speed change table and the gang drill device are combined to realize efficient drilling, the conveying table is subjected to two-section type speed change design, specifically, the first belt is driven by the first driving wheel, and the second belt is driven by the second driving wheel, so that the sectional speed change of the conveying table is realized, and the conveying table has the advantages of simple structure and convenience in assembly;

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
