The realization form of existing equipment is mostly the truss structure, and the unilateral is connected with jack catch moving part, mostly is the stand-alone work, has the line less, in industrialization and unmanned modern intelligent factory, obviously can not satisfy the requirement. Therefore, the existing equipment still has the following defects in application at present:

1. the workpiece is clamped by the clamping mechanism in the machining process, but the existing solution only has one set of clamping jaw mechanism, so that the machining units of the machine are in a waiting state in the workpiece clamping, conveying and outputting processes, and the machining efficiency of the equipment is greatly reduced.

2. The existing platforms for conveying and inputting workpieces are mostly manual conveying, the workload of operators is increased, the operation efficiency is influenced, and the industrial mass production requirement cannot be met.

3. The scheme of configuring the belt-driven roller table conveying mechanism has the disadvantages that the additional X/Y positioning mechanism is additionally arranged, the positioning requirement of the workpiece is high, the time is long and the efficiency of the machine is influenced in practical application because the X/Y directions need to be positioned, and in addition, the manufacturing cost is high because the positioning needs the motion control of the servo shaft, so the popularization of the machine is influenced.

4. A single mode of operation is contradictory to the customer's multiple requirements, which has to spend more cost and space for the needs of multiple process scenarios and conditions.

Meanwhile, the automatic conveying and positioning of the plate are also a very critical procedure in the plate processing process, which not only relates to the production efficiency of the whole production line, but also influences the processing precision and quality of the workpiece.

At present, workpieces are conveyed and positioned through a conveying table, servo shafts in X/Y directions are additionally arranged on the conveying table, and the servo shafts are used for positioning the workpieces to preset zero positions of a machine tool. However, the following disadvantages still exist in the current market of the transmission station:

1. the positioning of the plate in the X/Y directions can be realized only by driving the plate pushing mechanism by two sets of servo motors to push the plate to the preset zero baffle, so that the positioning of the plate is realized, and the cost of the scheme is relatively high;

2. the mechanical structure design of the servo shaft is relatively complex, the requirement on space is high, and enough space is needed for arranging the shaft moving component, so that the multipurpose design of the conveying table has certain limitation.

3. Based on the requirements of safety and motion logic, the servo shaft needs to run slowly in the starting and stopping processes, and certain sequentiality exists in the X direction and the Y direction, so that the positioning time of a workpiece is long, and the efficiency of equipment is influenced.

4. Due to the cost and the mechanism complexity, the double-channel conveying and positioning are greatly limited, and the large-scale popularization and application are not facilitated.

When the plate is processed by utilizing the through type multi-mode drilling processing center, the method specifically comprises the following steps:

according to the plate processing mode, the plate to be processed is placed on the plate conveying channel corresponding to the conveying table 46, the conveying roller table 2 conveys the plate to be processed along the plate feeding direction, in the process of conveying the plate to be processed, the positions of the plate to be processed in the Y direction and the X direction can be positioned through the backup plate mechanism 4 and the measuring mechanism 3,

when the plate to be processed reaches the clamping position, the brush platform 6 lifts the plate to be processed to the clamping height, the plate to be processed is transferred to the working platform 45 by the clamping hand system 43 at the same side,

then, the plate to be processed is drilled and milled by the drilling and milling device 72 fixed on the main frame 48, and the processed plate is moved to the output station by the clamping system 43.

The through type multi-mode drilling machining center can realize the switching of three working modes, namely a sequential machining mode, a synchronous machining mode and a wide workpiece machining mode, so that a more flexible machining selection scheme according to factory resource conditions is provided for customers.

When the plate processing mode is the sequential processing mode, as shown in fig. 20, the plates to be processed can be sequentially processed, that is, the plates to be processed are conveyed to the working platform 45 from the left plate conveying channel on the conveying table 46 for processing, when the plates start to be processed, the next plate to be processed is conveyed to the working platform 45 from the right plate conveying channel on the conveying table, and the right gripper system performs clamping preparation on the next plate to be processed. When the left plate to be processed is processed, the plate to be processed is moved to the output table 47 by the clamping device (left clamping system) on the same side, and the plate on the right plate conveying channel is moved to the working platform 45 by the right clamping system to start processing. After the output table 47 finishes outputting the left plate to be processed, the left gripper system immediately returns to the conveying table to start clamping preparation of the next plate, and the steps are repeated until all the plates are processed in sequence. In the process, the clamping hand systems on the two sides work coordinately, so that the invalid time of the drilling and milling device for waiting for workpiece input is greatly reduced, and the machine efficiency is greatly improved.

When the plate processing mode is the synchronous processing mode, as shown in fig. 21, two plates can be simultaneously input and processed, that is, two plates to be processed are simultaneously conveyed by the left plate conveying channel and the right plate conveying channel on the conveying table 46, then the left and right clamping systems respectively and independently clamp the plates to be processed on the corresponding sides to enter the working platform, and in the process, the left and right clamping systems respectively and independently work. When two plates to be processed are placed on the working platform 45, the two upper drilling and milling devices are arranged on the left side and the right side respectively, and drilling and milling operations are respectively and independently performed on the two plates to be processed; according to the actual processing requirement, if a lower drilling and milling processing device is required, the lower drilling and milling processing device can simultaneously drill and mill two plates to be processed. The machining center under this mode is divided into two left and right machining areas, and two machining areas independent work, is equivalent to two machines simultaneous working, has promoted the machining efficiency of panel greatly.

When the plate processing mode is the wide workpiece processing mode, as shown in fig. 22, the processing requirement of the wide plate can be satisfied. In this processing mode, the plate to be processed is only conveyed to the working platform 45 by the two plate conveying channels on the conveying table at the same time for processing, and the gripper device 55 corresponding to the other plate conveying channel is not started. For example, during machining, the right-side clamping hand system is stopped at a preset position and is not started, the plates to be machined are simultaneously conveyed through the left-side plate conveying channel and the right-side plate conveying channel on the conveying table and then are moved to the working platform through the left-side clamping hand system, and then the two upper drilling and milling machining devices and the lower drilling and milling machining devices can perform machining actions on the whole working platform. The machining center in the mode only has one machining area, only the clamping hand system on one side works, and the machining center is provided with sufficient machining areas to machine wide workpieces, so that special requirements of customers can be met.
