[0019] 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.

[0020] The utility model provides a modular industrial robot end tool quick connection device, such as Figure 1-Figure 3 As shown, it includes a rotating disk 1, a connecting arm 2 is installed on one side of the rotating disk 1, a tool connecting plate 3 is installed on the other side of the rotating disk 1, a tool clamping plate 4 is installed at the bottom of the tool connecting plate 3, a pressing plate 5 is arranged on the inner side of the tool clamping plate 4, a lifting rod 51 is installed on the top of the pressing plate 5, a threaded sleeve 31 is installed on the tool connecting plate 3, the top of the lifting rod 51 passes through the tool connecting plate 3 and extends into the threaded sleeve 31, the top of the threaded sleeve 31 is threadedly connected with a threaded pressing rod 32, and the bottom end of the threaded pressing rod 32 abuts against the top of the lifting rod 51.

[0021] The rotating disk 1 is the basic component of the entire connection device, which provides a rotating platform. This design allows the end tool to be flexibly adjusted in different directions to meet the needs of various work scenarios. The connecting arm 2 is used to connect the rotating disk (and the end tool connected to it) to the main body of the industrial robot. In this way, the robot can manipulate and move the end tool through the connecting arm. The tool connecting plate 3 is the main structure for connecting and fixing the end tool. It provides a stable platform for installing and supporting the tool clamping plate and other related components.

[0022] The tool holding plate 4 is used to hold and stabilize the end tool. By using it in conjunction with the pressure plate 5, the end tool can be ensured to remain stable during use. The main function of the pressure plate 5 is to fix the end tool by pressing. This design makes the replacement of the end tool quick and easy. When the threaded pressure rod is rotated, it moves up and down along the threaded sleeve. By tightening or loosening the threaded pressure rod, the up and down position of the lifting rod (and the pressure plate) can be controlled, thereby achieving rapid clamping or release of the end tool.

[0023] In this embodiment, a circular groove is provided at the end of the rotating disk 1 near the connecting arm 2 , a threaded opening 11 is provided at the upper portion of the circular groove, and a locking bolt 12 is installed in the threaded opening 11 to facilitate the rotation angle adjustment of the rotating disk 1 .

[0024] Specifically, a cushion block 13 is installed at the bottom end of the locking bolt 12 , and one end of the connecting arm 2 is stuck in the circular groove and is pressed and locked by the cushion block 13 , so as to facilitate the locking of the rotating disk 1 .

[0025] Furthermore, the tool holding plate 4 is an L-shaped structure, and the top of one end is welded and fixed to the bottom of the tool connecting plate 3 to ensure that the tool holding plate 4 is fixed.

[0026] Furthermore, a handle 321 is installed on the top of the threaded pressure rod 32 to facilitate manual adjustment of the rotation of the threaded pressure rod 32 .

[0027] Furthermore, a spring 52 is provided between the pressing plate 5 and the tool connecting plate 3. The spring 52 is sleeved on the outside of the lifting rod 51. The top end of the spring 52 is connected to the tool connecting plate 3, and the bottom end of the spring 52 is connected to the pressing plate 5. The spring 52 is compressed between the pressing plate 5 and the tool connecting plate 3, and it applies a continuous downward preload force to the pressing plate 5. This preload force helps to ensure that the end tool is tightly fixed in the tool clamping plate 4, and the stability of the tool can be maintained even in the event of vibration or impact generated during the operation of the robot. When the industrial robot is operating, vibration or impact force may be generated. The spring 52 can absorb these vibrations and impact forces, reduce the risk of damage to the connection device and the end tool, and extend their service life. Since the spring 52 has a certain elasticity and scalability, it can automatically adjust the position of the pressing plate 5 to a certain extent to adapt to end tools of different thicknesses or shapes. This automatic adjustment capability improves the versatility and flexibility of the connection device.

[0028] Furthermore, a serrated groove is provided at the bottom of the front end of the pressing plate 5, and a serrated strip is installed on the inner lower surface of the tool clamping plate 4, which has an anti-slip effect when clamping the tool.

[0029] When the modular industrial robot end tool quick connection device of the utility model is used, the end tool is first placed between the tool clamping plate 4 and the pressure plate 5. The threaded pressure rod 32 is rotated (handle 321 is used for convenient operation) to move it downward, thereby pushing the lifting rod 51 and the pressure plate 5 to press the end tool downward. The spring 52 is compressed in this process, generating a downward preload force to ensure that the end tool is tightly fixed in the tool clamping plate 4. The front bottom of the pressure plate 5 is provided with a serrated groove, which cooperates with the serrated bar on the lower inner side of the tool clamping plate 4, enhancing the anti-slip effect during clamping, and ensuring that the end tool will not slide or fall off during operation.

[0030] The angle of the rotating disk 1 can be adjusted as needed so that the end tool can work in different directions. After the adjustment is completed, one end of the connecting arm 2 is tightly locked in the circular groove of the rotating disk 1 by tightening the locking bolt 12 (with a pad 13 at the bottom) to ensure that the angle does not change.

[0031] When the end tool needs to be replaced, the threaded pressing rod 32 only needs to be rotated in the reverse direction to move the pressing plate 5 upward under the elastic force of the spring 52 to release the clamping force on the end tool. After taking out the old tool and putting in the new tool, the threaded pressing rod 32 is rotated again to tighten it.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
