[0002] Tool inspection equipment is usually used to inspect and test tooling during the manufacturing process. These devices can detect the accuracy, durability, performance and other key features of tooling to ensure that the tooling can operate normally and meet production requirements. In the welding process of automobile bodies, due to the use of automated welding technology, the operation of the equipment and the welding quality are particularly important. Robotic automatic welding is used in the automated welding process. Robotic welding workstations need to be equipped with tooling sensors to quickly troubleshoot, shorten alarm time, and ensure production. Therefore, tooling inspection equipment based on PLC control systems is required.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a tool detection device based on a PLC control system, including a sensor 1, a connecting plate 2 is fixedly connected on both sides of the sensor 1, a connecting column 3 is fixedly connected inside the connecting plate 2, a limiting ring 6 is fixedly connected inside the connecting column 3, a connecting rod 4 is slidably connected inside the connecting column 3, a limiting assembly is arranged on the outer wall of the connecting rod 4, a conical column 7 is fixedly connected at one end of the connecting rod 4, a cavity 8 is opened inside the connecting column 3, a ball 9 is arranged inside the connecting column 3, the outer wall of the ball 9 is rotatably connected inside the cavity 8, a first spring 10 is sleeved on the outer wall of the connecting rod 4, one end of the first spring 10 is fixedly connected to the bottom of the limiting assembly, and the other end of the first spring 10 is fixedly connected to the top of the limiting ring 6, a connecting seat 15 is slidably connected to the outer wall of the connecting column 3, a slot 17 is opened inside the connecting seat 15, the outer wall of the ball 9 is embedded in the slot 17, and the limiting assembly includes a limiting ring 5, the limiting ring 5 is fixedly connected to the outer wall of the connecting rod 4, and the outer wall of the limiting ring 5 is slidably connected to the inside of the connecting column 3;

[0026] Specifically, during the installation of the sensor 1, the sensor 1 only needs to be inserted into the interior of the connecting seat 15 through the connecting column 3. The shape of the ball 9 inside the connecting column 3 and the interior of the card slot 17 is designed just right, so that the ball 9 can be smoothly embedded in the card slot 17 to achieve locking. The diameter of the cavity 8 is slightly smaller than the diameter of the ball 9, so that the ball 9 can extend out of the cavity 8 and fit into the card slot 17, but the ball 9 will not fall due to excessive pressure. At the same time, the conical column 7 is connected to the connecting rod 4, and the ball 9 can be continuously resisted by the tension support of the first spring 10, so that the ball 9 can be firmly embedded in the card slot 17 and will not retract easily. When the sensor 1 needs to be disassembled, it is only necessary to press the connecting rod 4, squeeze the connecting rod 4 into the connecting column 3, drive the conical column 7 to descend through the connecting rod 4, and then separate the conical column 7 from the ball 9, and the connecting column 3 can be separated from the connecting seat 15. This design makes the disassembly process both quick and safe. When sensor 1 is damaged, the Rockwell (hereinafter referred to as AB) PLC control system can monitor in real time. The ABPLC control system includes the ABPLC control system, the touch screen (HMI) system, and the tooling sensor. Once sensor 1 is damaged, the ABPLC control logic will be immediately written and combined with the HMI real-time display. The touch screen can alarm in real time and jump out of the screen, and the damaged position will turn red. This design allows us to accurately find the damaged position at the first time without complicated verification and searching. This not only improves work efficiency, but also greatly saves time and energy.

[0027] Reference Figure 3 and Figure 4 , a slider 16 is fixedly connected to one end of the connecting seat 15, a base 11 is provided on the outer wall of the slider 16, a mounting plate 12 is fixedly connected to the outer wall of the base 11, a limiting groove 13 is provided inside the base 11, the outer wall of the slider 16 is slidably connected inside the limiting groove 13, a rack 14 is fixedly connected inside the base 11, a limiting plate 18 symmetrically arranged is slidably connected inside the slider 16, a tooth block 19 is fixedly connected to one side of the limiting plate 18, a telescopic rod 20 is provided inside the slider 16, a second spring 21 is sleeved on the outer wall of the telescopic rod 20, both ends of the telescopic rod 20 and the second spring 21 are fixedly connected between the limiting plate 18, and the outer wall of the tooth block 19 is embedded in the rack 14;

[0028] Specifically, the base 11 is installed on the equipment to be detected through the mounting plate 12. Next, according to the size of the sensor 1, the distance of the connecting seat 15 in the base 11 can be adjusted, and the slider 16 can be driven to slide in the base 11 directly by pinching the connecting seat 15. The connecting seat 15 will be limited in the limiting groove 13 to ensure the stability of its position. A tooth block 19 is provided inside the slider 16, and the tooth block 19 is embedded between the teeth on the rack 14 to accurately position the slider 16. In order to prevent the tooth block 19 from accidentally slipping out during operation, the tooth block 19 is also supported by the tension of the second spring 21, so that it remains stable inside the rack 14, reducing the risk of misoperation.

[0029] Working principle: When using the tooling inspection equipment based on the PLC control system, first install the base 11 on the equipment to be inspected through the mounting plate 12, and then adjust the distance of the connecting seat 15 in the base 11 according to the size of the sensor 1. Simply pinch the connecting seat 15 to drive the slider 16 to slide in the base 11. The connecting seat 15 is limited in the limiting groove 13 by the slider 16. The slider 16 is positioned by the internal tooth block 19 that is engaged between the teeth on the rack 14. The tooth block 19 is limited inside the slider 16 by the limiting plate 18. The tooth block 19 is supported by the tension of the second spring 21, so that the tooth block 19 is embedded in the rack 14 and is not easy to slide out. When the sensor 1 is subsequently installed, it is only necessary to directly insert the sensor 1 into the connecting seat 15 through the connecting column 3, so that the ball 9 in the connecting column 3 is embedded in the slot 17 for locking. The diameter of the cavity 8 is slightly smaller than the diameter of the ball 9, so the ball 9 can extend out of the cavity 8 and be embedded in the slot 17, but the ball 9 will not fall off. And the ball 9 can be embedded in the card slot 17 and will not retract through the resistance of the conical column 7. The conical column 7 is connected to the connecting rod 4, and the connecting rod 4 is supported by the tension of the first spring 10, so that the conical column 7 can continuously resist the ball 9 through the cone surface. When it needs to be disassembled, just press the connecting rod 4, squeeze the connecting rod 4 into the connecting column 3, and drive the conical column 7 to descend through the connecting rod 4, so that the conical column 7 and the ball 9 are separated, and the connecting column 3 can be separated from the connecting seat 15. When the sensor 1 is damaged, it is monitored by the Rockwell (hereinafter referred to as AB) PLC control system. The Rockwell (hereinafter referred to as AB) PLC control system includes an ABPLC control system, a touch screen (HMI) system, and a tooling sensor. When the sensor 1 is damaged, the touch screen can alarm in real time and jump out of the screen through the combination of ABPLC control logic programming and HMI real-time display. The damaged position turns red, and there is no need for complicated verification and search, and the damaged position can be found efficiently and accurately.
