Problems solved by technology

[0003] The workpiece of the machine tool is a copper sheet. The processing content is that the main shaft rotates at a high speed and the feed shaft drives the tool to turn the surface of the copper sheet to remove the oxide layer on the surface. The next step is to drive the aluminum bar forward and friction weld the copper sheet. The key point of the first step is that there must be a copper sheet and the oxide layer on the surface of the copper sheet has been processed. If there is no workpiece for the next process, the aluminum rod will be contacted and friction-welded with the chuck, and the aluminum rod will become a waste part; if there is a workpiece but If the oxide layer on the surface of the workpiece is not processed and then welded in the next process, it will cause unqualified welding and waste products
[0004] Now there are many ways to detect the presence or absence of workpieces, such as photoelectric sensors, displacement sensors, infrared rays, digital photography, etc., but some machine tools cannot be installed with these detection devices due to structural limitations, and the price is also relatively expensive, and generally they are used to detect the presence or absence of workpieces. It is difficult to detect whether the process with a small amount of workpiece processing is processed

Embodiment Construction

[0016] Such as figure 1 with figure 2 As shown, an automatic charge machine tool workpiece detection method, the steps are as follows: 1) Detection structure construction: including relays, wires, power supplies, and system input signal monitoring points;

[0017] 2) Relay reset, monitoring signals from zero;

[0018] 3) The detection structure is placed on the side of the tool, a wire is in contact with the tool, the relay wire is electrically, the monitoring signal is changed from 0 to 1, and the process continues;

[0019] 4) The monitoring signal has been 0, then the process is wrong, stops working, and detects whether there is no workpiece or workpiece.

[0020] The wires of the relays in the relay in step 1) are connected to the tool contact, and the relay is positive to turn on the power.

[0021] In step 3), the NC and the PLC interaction signal is DB125.1 in the detection structure, the corresponding NC address is $ A_IN [18]; when the tool is in contact with the workpie...

Abstract

The invention relates to an automatic feeding machine tool workpiece detection method and belongs to the field of machining. A wire of a relay coil makes contact with a tool, whether a workpiece exists or not and whether the workpiece is machined or not are judged according to NC and PLC interaction signals, the situations that welding is unqualified, and waste products are generated are avoided,work efficiency is improved, and product quality is guaranteed.

Description

Technical field [0001] The present invention relates to a detection method, particularly an automatic charge machine tool workpiece detection method, belonging to the field of machine tool manufacturing processing. Background technique [0002] Today's manufacturing automation is getting higher and higher. For automatic charge machine detection workpieces, it is important to process whether processing is important. No workpiece can damage the machine tool, and the workpiece is not processed into the next process. It will cause waste wastewaves. Therefore, it is very important for the machine tool workpieces processed by automatic upper and lower materials. [0003] The machine tool processing member is a copper sheet, and the processing content is the first spindle high-speed rotary feed axis drive the knife to cut the surface of the copper sheet, and the surface oxide layer is removed. The next order is the top-bound aluminum rod forward and the copper sheet for friction welding...
