[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] like Figure 1-Figure 3 As shown, the utility model is a mechanical up and down floating detection system, including a combination of an active protection system and a passive protection system. The active protection is performed by a sensor 5, and the passive protection is performed by a mechanical up and down floating probe rod 7. Specifically, it includes a universal pressure wheel 1, a linear bearing 2, a sensor sheet 3, a mounting frame 4, a sensor 5, a driving cylinder 6 and a probe rod 7. The linear bearing 2 is installed on one side of the side wall of the mounting frame 4, and the driving cylinder 6 is arranged on the other side of the side wall of the mounting frame 4. At the same time, the push rod of the driving cylinder 6 is connected to the side wall of the mounting frame 4. When the push rod of the driving cylinder 6 extends or retracts, it can drive the mounting frame 4 to extend or retract together. One end of the probe rod 7 passes through the linear bearing 2 and is arranged above the linear bearing 2. The outer sleeve of the probe rod 7 is provided with a compression spring 10, which is arranged between the universal pressure wheel 1 and the linear bearing 2. The upper end of the probe rod 7 is equipped with a sensor plate 3, and the lower end is equipped with a universal pressure wheel 1. The top of the mounting frame 4 is equipped with a sensor 5 near the position of the sensor plate 3. The position and size of the sensor 5 are sufficient to ensure that the sensor 5 can send a signal to the sensor 5 after the probe rod 7 is lifted. When the probe rod 7 moves upward, it can drive the sensor plate 3 to move upward and enter the sensing range of the sensor 5. The sensor 5 and the drive cylinder 6 are electrically connected to the central system PLC respectively. The PLC is equipped with an alarm. The PLC can control the start or stop of the sensor 5 and the start or stop of the drive cylinder 6. The PLC system and the alarm are both existing technologies. In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] When the universal pressure wheel 1 is subjected to an upward external force, it will move upward, and the probe rod 7 can move upward along the linear bearing 2. At this time, the compression spring 10 is compressed. When the external force disappears, the compression spring 10 is released and gradually returns to its original state. In the process of the compression spring 10 returning to its original state, the probe rod 7 also gradually moves downward as the spring recovers, thereby realizing the up and down floating of the probe rod 7.

[0023] A guide block 8 is installed on the mounting frame 4. The guide block 8 is arranged below the linear bearing 2. A circular arc surface structure is provided on the side of the guide block 8 facing the probe rod 7. At the same time, the circular arc surface structure is in contact with the outer wall of the probe rod 7, which can effectively prevent the probe rod 7 from shifting and deviating, thereby improving the reliability of the detection system.

[0024] A limit block 11 is installed on the mounting frame 4. The limit block 11 is arranged above the linear bearing 2. A semicircular ring structure is provided on the side of the limit block 11 facing the probe rod 7. At the same time, the probe rod 7 is arranged in the semicircular ring structure of the limit block 11, that is, the semicircular ring structure of the limit block 11 can effectively wrap and surround the probe rod 7. This structure can effectively ensure the stability of the top end operation of the probe rod 7, thereby effectively ensuring the stability and reliability of the up and down floating of the probe rod 7.

[0025] A positioning pin 9 is mounted on the mounting frame 4 and is located below the universal pressure wheel 1. After the workpiece is placed at the detection point, the positioning pin 9 is inserted into the detection positioning point set on the workpiece, which can effectively avoid problems such as inertia deviation of the workpiece during the detection process, thereby improving safety and detection accuracy.

[0026] The detection system described in the present invention is connected to the detection fixture via a mounting frame 4. Specifically, the L-shaped connecting plate at the top of the mounting frame 4 is mounted on the detection fixture. A connecting rail is horizontally provided at the mounting position of the detection fixture, and the L-shaped connecting plate is mounted on the connecting rail. This ensures that the detection system can slide along the slide rail of the detection fixture. Then, the driving cylinder 6 of the detection system is fixed to the detection fixture via the included connecting frame. After installation, the driving cylinder 6 is activated, and when its push rod extends, it can push the mounting frame 4 forward. When the push rod retracts, it can drive the mounting frame 4 backward.

[0027] The detection system described in this utility model is primarily used for error prevention detection and is applicable to the detection of a variety of different product models. For different product models, due to the different product sizes, the distance between the positioning pin 9 and the universal pressure wheel 1 can be adjusted, that is, different product models correspond to different detection distances. Specifically, different product model detection systems correspond to different probe rod 7 lengths. The positional relationship between the sensor plate 3 and the sensor 5 at the top of the probe rod 7 remains unchanged. Therefore, different probe rod 7 lengths will be reflected as different distances between the universal pressure wheel 1 and the positioning pin 9, thereby enabling the detection of different product models.

[0028] By installing multiple detection systems with different probe rod lengths 7 on the product detection tooling, it is possible to simultaneously detect different types of product workpieces, effectively improving work efficiency. In the description of this utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0029] When the product workpiece needs to be inspected, the product workpiece is placed at the inspection point position of the inspection tooling, and then the cylinder and sensor 5 are started, driving the cylinder 6 to extend the push rod and push the mounting bracket 4 forward. During the process of being pushed out, the mounting bracket 4 gradually approaches the workpiece to be inspected until the positioning pin 9 is connected with the inspection positioning point on the workpiece to be inspected, and the universal pressure wheel 1 begins to contact the workpiece. When the height of the product workpiece is greater than the universal pressure wheel 1, when the workpiece contacts the universal pressure wheel 1, it will resist the universal pressure wheel 1 and give the universal pressure wheel 1 an upward force, causing the universal pressure wheel 1 to move upward, and then push the probe rod 7 and the sensor plate 3 to move upward together. At this time, the compression spring 10 is gradually compressed to store energy. When the lifting height of the sensor 5 reaches the sensing range of the sensor 5, the sensor 5 will transmit a signal to the PLC, and the PLC system will trigger an alarm. The PLC system will immediately shut down and emit an audible and visual alarm to remind the staff to handle it.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
