Description

Technical Field

[0001] This utility model belongs to the field of safety protection technology for machining centers, and specifically relates to an alarm mechanism for machining centers. Background Technology

[0002] To ensure the safety of operators, machining centers are usually equipped with protective doors. These doors can effectively block metal shavings, coolant, and tool fragments, preventing them from splashing out of the work area and causing injury to personnel.

[0003] However, existing alarm devices for machining centers have limitations. Current alarm systems primarily focus on real-time monitoring of key operating parameters, such as temperature. Excessively high temperatures may indicate equipment malfunctions, such as insufficient lubrication or motor overload. Abnormal vibrations may indicate loose or unbalanced components. Monitoring tool wear helps in timely tool replacement to ensure machining accuracy. However, traditional alarm devices do not address the crucial safety factor of whether the protective door is fully closed. In actual production scenarios, operators may start the machining center without fully closing the protective door due to busyness or negligence, thus exposing themselves to danger. Once the machining center is running, splashing metal shavings, coolant, or tool fragments could cause serious injury to the operator, posing a significant threat to their life and the company's normal production.

[0004] Therefore, in order to solve the above problems, it is necessary to design an alarm mechanism for machining centers. Utility Model Content

[0005] The purpose of this invention is to provide an alarm mechanism for machining centers to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an alarm mechanism for a machining center, comprising: A baffle plate, suitable for installation on a protective door and for moving with the protective door; A displacement sensor, suitable for mounting on the housing of a machining center, is used to measure the distance between itself and a baffle and to upload the measurement data in real time. An alarm light, suitable for installation on the housing of a machining center; The main control module is electrically connected to the displacement sensor and the alarm light; The main control module is adapted to receive measurement data uploaded by the displacement sensor and control the alarm light to illuminate when the measurement data is inconsistent with the standard distance value.

[0007] Furthermore, a human presence sensor and a buzzer are provided on one side of the displacement sensor; wherein... The main control module is electrically connected to the human presence sensor and the buzzer; and The human presence sensor is adapted to upload detection data to the main control module; The main control module is adapted to communicate with the spindle drive system; When the human presence sensor detects a person in the work area, and the main control module receives a signal of spindle rotation and alarm light 3 illuminates, the main control module controls the buzzer to start.

[0008] Furthermore, a support rod is provided at the bottom of the baffle; The bottom of the support rod is provided with a first connecting seat; wherein The first connecting seat is installed on the protective door.

[0009] Furthermore, a second connecting base is provided at the bottom of the displacement sensor; wherein The second connecting seat is mounted on the housing of the machining center.

[0010] The beneficial effects of this utility model are: (i) The baffle moves with the protective door. The displacement sensor measures the distance between itself and the baffle in real time and uploads the measurement data to the main control module. The main control module compares the received measurement data with the preset standard distance value. When the measurement data is inconsistent with the standard distance value, it indicates that the protective door is not in the normal closed position. The main control module controls the alarm light to light up to remind the operator that the protective door is in an abnormal state. By monitoring the position status of the protective door in real time, the situation of the protective door not being closed or not being fully closed can be detected in time, avoiding the operator from starting the machining center when the protective door is not properly closed. This effectively reduces the risk of the operator being injured by metal chips, coolant and tool fragments, and improves the life safety of the operator.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0017] like Figures 1 to 4 As shown, this embodiment provides an alarm mechanism for a machining center, including: A baffle 1 is suitable for being installed on a protective door and moving with the protective door; a displacement sensor 2 is suitable for being installed on the machining center housing to measure the distance between itself and the baffle 1 and upload the measurement data in real time; an alarm light 3 is suitable for being installed on the machining center housing; a main control module is electrically connected to the displacement sensor 2 and the alarm light 3; the main control module is suitable for receiving the measurement data uploaded by the displacement sensor 2 and controlling the alarm light 3 to illuminate when the measurement data is inconsistent with the standard distance value; wherein the baffle 1 is installed on the protective door and moves with the protective door, serving as a reference for the displacement sensor 2 to measure the distance; wherein the alarm light 3 is set to warn the operator when it illuminates; wherein the main control module adopts, but is not limited to, a PLC.

[0018] In this embodiment, the baffle 1 moves with the protective door, and the displacement sensor 2 measures the distance between itself and the baffle 1 in real time and uploads the measurement data to the main control module. The main control module compares the received measurement data with a preset standard distance value. When the measurement data is inconsistent with the standard distance value, it indicates that the protective door is not in the normal closed position. The main control module controls the alarm light 3 to light up to remind the operator that the protective door is in an abnormal state. By monitoring the position status of the protective door in real time, the situation of the protective door not being closed or not being fully closed can be detected in time, avoiding the operator from starting the machining center when the protective door is not properly closed.
