Monitoring equipment for CNC machining

This creation relates to a monitoring device for CNC machining, in particular a monitoring device that ensures that the operator of the CNC machine tool performs the inspection of the machining tool.

The Computer Numerical Control Machine Center (Computer Numerical Control Machine Center) is a device commonly used in the industry to process workpieces. It is mainly designed by the program and executed by the computer, but can be operated without manual control. The programmed program execution can be done accurately even with fairly complex machining programs.

After the workpiece is machined, if the measured dimensions are not accurate, the cause may be caused by damage to the tool used in CNC machining, and the damage may be caused by damage to the tool used in CNC machining. Due to frequent machining, the tool used for machining must be tested when a certain number of machining times arrives to avoid the problem of poor precision of the workpiece due to damage to the machining tool.

At present, the detection of machining tools on the production line is detected when a certain number of machining times arrives. The so-called machining times are usually based on the number of workpieces processed. When the number of workpieces processed arrives, the operator arrives at the arrival. The number of workpieces is dimensioned. If the dimensional error is within the expected range, the tool is not replaced; however, if the dimensional error has exceeded the expected range, the tool must be replaced.

However, based on practical experience, it can be seen that the operator himself may not immediately measure the size of the workpiece when the number of processed workpieces arrives due to negligence or laziness; or the operator may not clearly explain the shift during the shift, or When the number of workpieces processed arrives, the measurement of the workpiece size is not possible immediately. Therefore, it is unreliable to manually measure the size of the workpiece to confirm whether the machining tool needs to be replaced, so it is necessary to further improve it.

The main purpose of the present invention is to solve the above problems and provide a monitoring device for CNC machining. The number of workpieces that have been processed by the CNC machine tool monitored by the input unit is recorded and recorded in the host, and the number of workpieces accessed is When the preset value is reached, the warning unit will issue a warning to inform the operator to detect the machining tool, and it is mandatory to input a detection value to the host to stop the warning, so that the operator can perform the detection of the machining tool and avoid the cause. The detection is not true and the accuracy of the workpiece is not good.

For the purpose of the foregoing, the present invention provides a monitoring device for CNC machining, wherein a host is electrically connected to a warning unit and a transmission interface, and the host is electrically connected to the monitored CNC tool by the transmission interface. Accessing the monitored CNC machine tool data to the host, an input unit is electrically connected to the host via the transmission interface, and the input unit accesses the number of workpieces that have been processed by the monitored CNC machine tool and records on the host, when When the number of workpieces accessed reaches a preset value, the warning unit of the host driver electrically connects to notify the operator of the CNC machine tool to perform the detection of the machining tool, and forcibly has to input a detection value to the host. Stop the alert.

The present invention provides a monitoring device for CNC machining. As shown in FIG. 1 , a host 1 is electrically connected to a warning unit 2 and a transmission interface 3, and the host 1 is connected to the transmission interface 3 and the CNC machine tool 4 monitored. Electrically connected, and the information of the CNC machine tool 4 that can be accessed and monitored is in the host 1. An input unit 5 is electrically connected to the host 1 via the transmission interface 3, and the input unit 5 accesses the CNC machine tool 4 that has been monitored and processed. The number of workpieces is recorded in the host 1. When the number of workpieces accessed reaches a preset value, the warning unit 2 that drives the electrical connection by the host 1 issues an alert to notify the operator of the CNC machine tool 4 to perform the detection of the machining tool, and It is mandatory to input a detection value to the host 1 to stop the warning.

As shown in FIG. 1, the host 1 of the present embodiment is electrically connected to a display unit 6 to display an operation interface for inputting the detected value when the processing tool is detected. As shown in Fig. 1, the input unit 5 of the present embodiment includes a counter 51 for calculating the number of workpieces that have been previously processed. In addition, the input unit 5 of the embodiment includes a measuring tool for measuring the size of the workpiece, and the detected value is a size obtained by the operator measuring the workpiece reaching the preset value by the measuring tool, and the measuring device passes through the transmission interface 3 The host 1 is electrically connected, and the size obtained by the foregoing measurement can be directly accessed and recorded in the host 1. In detail, the counter 51 is a strip scanner, and the gauge is a digital vernier caliper 52 or a digital centimeter card 53. In addition, the alert unit 2 is an alerter who sounds an alarm (eg, a buzzer) or a light (eg, an indicator light).

In actual operation, each workpiece processed by the CNC will be scanned by the counter 51 set as the bar scanner (the bar code), and the bar coded workpiece will be processed after the bar code of the next workpiece. Scan to accumulate the number of workpieces processed. It is assumed that the preset value is 10, that is, the machining tool must be detected after the machining of 10 workpieces is completed. Therefore, when the workpiece is scanned by the bar code until the number of completed workpieces reaches the 10th, the warning unit 2 is sounded. Or the light gives an alarm. At this time, the operator can measure the size of the 10th completed workpiece by using the above-mentioned digital vernier caliper 52 or digital centimeter 5, and if the dimensional error is within the expected range, the processing can be continued, and the next pre-processing The value is detected when the value is reached; however, if the dimensional error of the detected workpiece exceeds the expected range, the operator can replace the processed tool. Regardless of whether the measured dimensional error is within the expected range, the operator must input the measured value (ie the size of the workpiece) to the host, and the host can stop the warning by forcing the operator to input the detected value to Host 1, allowing the operator to perform the inspection of the machining tool, avoiding the accuracy of the workpiece due to false detection

In addition, the host 1 is connected to the manufacturing execution system 7 via the transmission interface 3 via a network communication, and the manufacturing execution system 7 is communicatively coupled to an enterprise resource planning system 8.
