The invention discloses unmanned terminal equipment for mirror image motion composite cutting, and relates to the field of numerically-controlled cutting machine tools. Chucks (spindles) of mirror image composite cutting structures are designed on a table top of a main base frame, the chucks can oppositely and accurately clamp a workpiece in a matched mode to change the cutting position, the cutting precision of a mold position is improved, the cutting requirements of a visible surface and an invisible surface are met, and synchronous machining of mirror image composite cutting is achieved; amirror image turning tool magazine, a universal tool magazine, an intermediate transfer manipulator and the like are further arranged between the mirror chucks (spindles) to form mirror image type coordinate system trajectory motion cutting; besides, a workpiece unloading manipulator, a feeding mechanism, a caching mechanism, a fixed-length cutting mechanism, a conveying mechanism and a discharging mechanism are integrated into complete equipment in the upstream and downstream positions of a main machine, under interactive control of a double-motion control system and a programmable logic controller, logistics type unmanned cutting from a blank to a finished product is truly achieved, the efficiency is remarkably improved, the cutting range is further expanded, the input cost is greatly reduced, and a breakthrough is provided for manufacturing of a high-precision and high-efficiency cutting machine tool.

Description

technical field [0001] The invention relates to a general equipment manufacturing industry, in particular to a numerical control compound cutting machine tool. Background technique [0002] The same technology has not been seen before the application date of the present invention (see the novelty search report). The visible technical feature of the compound cutting machine tools such as CNC turning and milling and the auxiliary equipment for the upper and lower workpieces is that the chuck for clamping the workpiece is the main axis X coordinate, and its radial direction The Z coordinate design has an automatic tool assembly. There are two similar methods for cutting the tool assembly. One is to arrange and install various cutting tools such as turning, milling, and drilling on the electric slide assembly, according to the needs of the workpiece cutting process. The CNC command calls the corresponding tool assembly to perform X, Y, and Z trajectory movements to achieve the p...

Problems solved by technology

In addition, the feeding adopts the feeding tool consisting of hydraulic lifting and propulsion system. The feeding machine pushes the material from the hollow chuck, or directly uses the robot to put the pre-cut workpiece from the top of the operation door or machine tool (tool assembly) Put it into the chuck to complete the loading, and the cut workpiece is then grabbed by a robot or manually to complete the task of unloading the workpiece. Repeating this is very cumbersome

[0003] The cutting technology of the existing CNC machine tools has significantly improved the processing efficiency compared with the traditional cutting machine tools, reduced the processing cost, and the cutting precision, speed, shape, appearance and other process quality have also been significantly improved. However, the existing technology The disadvantage lies in the inability to meet the requirements of high-precision U-turn cutting for the same workpiece, especially for the workpiece with double heads. According to the existing technology, the machine tool must be turned around and re-loaded on the workpiece before performing secondary cutting. High precision cannot be guaranteed, let alone flow-type cutting without unmanned operation. The cutting efficiency is not high. In addition to the next cutting task, the double-station compound cutting machine tools available in the market only integrate and install a variety of cutting tools to increase the cutting speed. question

[0004] The existing auxiliary equipment loading and unloading system (including robot) around the CNC machine tool is to send the material to the hollow chuck and then cut the material or the end face of the car according to the requirements of the drawing. The workpiece, the chuck (spindle) and the tool station must all stop and wait, which is unsafe and takes up cutting time

In addition, the existing cutting processes such as: loading, cutting, unloading, turning, milling, drilling, etc., the processing time is staggered, it is impossible to achieve logistics-style continuous inertial cutting, and the actual cutting time has not been fully utilized. Serious waste of time and low efficiency

[0005] To sum up, most of the existing CNC machine tools are independent cutting units, which are labor-intensive and time-consuming, and the phenomenon of repeated investment is serious, occupying a large area of ​​the factory building, and the overall cost remains high. It is difficult to guarantee the cutting accuracy and the Efficiency, continuous inertial cutting processing cannot be realized, especially the dependence on digital control system, online monitoring system, and cutting process code program is difficult to overcome, and cannot meet the cutting needs of forward-looking logistics-style "unmanned chemical factories"
