[0059] Reference below Figure 1-Figure 7The clamping mechanism 300 for the electric gripper 10 according to the embodiment of the present invention is described. The clamping mechanism 300 is arranged at one end of the housing 100 of the electric gripper 10. The clamping mechanism 300 includes: a clamping seat 310, which is movably mounted on one end of the housing 100 along the axial direction of the housing 100. The clamping seat 310 is used to be connected to the rotating mechanism 200 of the electric gripper 10 in a transmission manner so that the clamping seat 310 rotates; a push plate 320, which is used to push the push plate 320. The push plate 320 is slidably mounted in the clamping jaw seat 310, and one end of the push plate 320 is used to connect with the clamping mechanism 500 of the electric gripper 10 so that the push plate 320 moves along the axial direction of the shell 100; the clamping jaw 330 is slidably connected to the end of the clamping jaw seat 310 away from the shell 100, and the clamping jaw 330 is slidably connected to the end of the push plate 320 away from the clamping mechanism 500, and the push plate 320 is used to drive the clamping jaw 330 to open or close along the radial direction of the shell 100.

[0060] Specifically, the clamping jaw base 310 can be designed into different shapes according to its function and appearance. It can be a single part formed by integral casting, or it can be a combination of multiple parts through welding, riveting, screw connection, etc. The structural material of the clamping jaw base 310 can be a metal material, such as stainless steel. Stainless steel has good corrosion resistance and high hardness, which can effectively improve the overall strength of the clamping jaw base 310, thereby significantly improving the overall strength and service life of the electric gripper 10. With such a configuration, the clamping jaw base 310 can provide a stable installation and support platform for the clamping jaw 330 to ensure the stability of the overall structure of the clamping jaw 330 and the electric gripper 10, thereby improving the stability and reliability of the electric gripper 10.

[0061] Furthermore, in the embodiment of the present invention, the electric gripper 10 further includes a rotating mechanism 200. The main shaft (not shown in the figure) in the rotating mechanism 200 can drive the clamping mechanism 300 to rotate relative to the housing 100. The clamping jaw seat 310 can be movably mounted on one end of the housing 100 via a bearing 370 along the axial direction of the housing 100. The axial direction of the housing 100 can be Figure 1 The direction indicated by X in the figure. The clamping jaw seat 310 can be fixedly connected to the main shaft of the rotating mechanism 200 by welding, threading, etc., so that the rotating mechanism 200 can drive the clamping jaw seat 310 to rotate relative to the housing 100, thereby realizing the rotation of the clamping jaw mechanism 300 relative to the housing 100.

[0062] The push plate 320 can be slidably mounted within the clamping jaw seat 310 via the first sliding member 350. The push plate 320 can slide within the clamping jaw seat 310 along the axial direction of the housing 100 via the first sliding member 350. In an embodiment of the present utility model, the electric gripper 10 further includes a clamping mechanism 500. A hollow rack (not shown) in the clamping mechanism 500 can drive the clamping jaw mechanism 300 to move axially relative to the housing 100. One end of the push plate 320 can be fixedly connected to the clamping mechanism 500 by welding, riveting, threading, or the like. In this manner, the clamping mechanism 500 can drive the push plate 320 to slide axially along the housing 100. The distance the push plate 320 slides axially along the housing 100 controls the opening of the clamping jaw 330. Thus, the clamping jaw 330 can be opened or closed by the cooperation of the clamping mechanism 500 and the push plate 320, thereby achieving precise gripping of the electric gripper 10.

[0063] The shape of the clamping jaw 330 can be configured as an irregular shape. The number of the clamping jaws 330 can be two. The two clamping jaws 330 can be relatively installed in the mounting groove 311 of the clamping jaw seat 310 along the radial direction of the housing 100. The radial direction of the housing 100 can be Figure 1 The direction indicated by Y in the figure. The clamping jaw 330 can be slidably connected to the end of the clamping jaw base 310 away from the housing 100 via the second sliding member 360, and the clamping jaw 330 can be slidably connected to the end of the push plate 320 away from the clamping mechanism 500 via the slider 321. With this arrangement, the push plate 320 can drive the clamping jaw 330 via the slider 321, and the clamping jaw 330 can slide on the clamping jaw base 310 along the radial direction of the housing 100 via the second sliding member 360, thereby realizing the opening or closing of the clamping jaw 330 in the radial direction of the housing 100, and further realizing the clamping action of the electric gripper 10.

[0064] According to the clamping mechanism 300 for the electric gripper 10 provided by the embodiment of the present invention, by providing a clamping jaw seat 310, the clamping jaw seat 310 can be driven by the rotating mechanism 200 to rotate relative to the housing 100, so as to realize the rotation of the clamping jaw mechanism 300 relative to the housing 100, and the clamping jaw seat 310 can provide a stable installation and support platform for the clamping jaw 330 to ensure the overall structural stability of the clamping jaw 330 and the electric gripper 10, thereby improving the stability and reliability of the electric gripper 10; by providing a push plate 320, the clamping jaw 330 can realize axial movement along the direction of the housing 100, and the clamping mechanism 500 can drive the push plate 320 along the housing 100. 00 slides in the axial direction, and the distance that the push plate 320 slides along the axial direction of the shell 100 can control the opening of the clamping jaw 330, so that the clamping jaw 330 can be opened or closed by the cooperation of the clamping mechanism 500 and the push plate 320, thereby realizing the precise clamping of the electric gripper 10; by setting the clamping jaw 330, the push plate 320 can drive the clamping jaw 330 through the slider 321, and the clamping jaw 330 can slide on the clamping jaw seat 310 along the radial direction of the shell 100 through the second sliding member 360, thereby realizing the opening or closing of the clamping jaw 330 in the radial direction of the shell 100, and then realizing the clamping action of the electric gripper 10.

[0065] Please continue to participate Figure 1-Figure 2 As shown, the clamping mechanism 300 provided according to the embodiment of the present invention further includes: a limiting block 340 , which is fixedly connected to the clamping jaw seat 310 , and the limiting block 340 is used to limit the clamping jaw 330 .

[0066] It should be noted that the shape of the limit block 340 can be constructed as a rectangular shape with supports (not shown in the figure) on both sides, and the limit block 340 can be fixedly connected to the clamping jaw seat 310 by welding, riveting, threaded connection, etc. The number of the limit blocks 340 can be two, and the limit blocks 340 can be installed at intervals on both sides of the mounting groove 311 in the clamping jaw seat 310 along the radial direction of the shell 100, and arranged opposite to the clamping jaw 330. The limit block 340 can limit the extreme position of the sliding of the clamping jaw 330 along the radial direction of the shell 100, thereby controlling the extreme position of the opening or closing of the clamping jaw 330. The material of the limit block 340 can be a metal material, for example: aluminum alloy. Aluminum alloy has light weight and high strength, and aluminum alloy has good plasticity and machinability. Such an arrangement can improve the strength of the limit block 340, thereby improving the service life of the electric gripper 10.

[0067] Please continue to see Figure 1-Figure 2 As shown, according to one embodiment of the present invention, the clamping mechanism 300 further includes: a first sliding member 350 , which is disposed between the clamping base 310 and the push plate 320 , and is fixedly connected to the push plate 320 .

[0068] Specifically, the first sliding member 350 can achieve a sliding connection between the push plate 320 and the clamping jaw 310. The first sliding member 350 can be installed between the push plate 320 and the clamping jaw 330 via a fixing plate 351. The fixing plate 351 can be fixedly connected to the push plate 320 by welding, riveting, threading, etc., so that the first sliding member 350 can be fixedly connected to the push plate 320 and slidably connected to the clamping jaw 310. The first sliding member 350 can be a roller, ball, roller, needle, etc., or a lubricating material (e.g., POM, polytetrafluoroethylene, grease). This is not specifically limited in this embodiment of the present invention, and users can select different first sliding members 350 according to different application scenarios.

[0069] Please continue to see Figure 1-Figure 3 As shown, according to another embodiment of the present invention, the end of the clamping jaw seat 310 facing away from the shell 100 has a mounting groove 311, and the clamping jaw mechanism 300 also includes: a second sliding member 360, the second sliding member 360 is fixedly connected to the clamping jaw 330, and the second sliding member 360 is slidably connected to the mounting groove 311.

[0070] Specifically, the shape of the mounting groove 311 can be constructed into a semicircular, U-shaped, or other irregular shape. The embodiment of the present invention does not specifically limit this. The user can select mounting grooves 311 of different shapes according to different application scenarios. The clamping jaw seat 310 can be slidably connected to the clamping jaw 330 through the mounting groove 311. The clamping jaw seat 310 can be fixedly connected to the limit block 340 through the mounting groove 311. The specific connection method can be welding, threaded connection, etc. Such an arrangement can ensure that the clamping jaw 330 and the limit block 340 are installed in a fixed position on the clamping jaw seat 310, ensuring the accurate alignment and fixation of the clamping jaw mechanism 300, thereby ensuring the stability and safety of the electric gripper 10.

[0071] The mounting slot 311 simplifies and speeds up the installation process of the gripper mechanism 300. Compared to methods that require complex positioning and fixing, the mounting slot 311 can reduce workload and assembly errors. The mounting slot 311 allows for quick removal and reinstallation of components such as the gripper 330 and the stopper 340, thereby reducing maintenance time and costs for the electric gripper 10.

[0072] Furthermore, the second sliding member 360 can be used to achieve a sliding connection between the push plate 320 and the clamping jaw seat 310. The second sliding member 360 can be installed between the clamping jaw seat 310 and the clamping jaw 330 via a connecting plate 361. The side of the connecting plate 361 facing away from the clamping jaw seat 310 can be fixedly connected to the clamping jaw 330 by welding, riveting, bolting, etc., thereby allowing the second sliding member 360 to be fixedly connected to the clamping jaw 330. The second sliding member 360 can be slidably installed in the mounting groove 311 of the clamping jaw seat 310, so that the clamping jaw 330 can slide within the clamping jaw seat 310 via the second sliding member 360.

[0073] Furthermore, the connecting plate 361 can be configured as a rectangle with sliding grooves (not shown) at both ends. The sliding grooves can be V-shaped, semicircular, U-shaped, etc., and are not specifically limited in this embodiment of the present invention. The connecting plate 361 can be constructed of the same material as the housing 100, and this is also not specifically limited in this embodiment of the present invention.

[0074] It should be noted that the second sliding member 360 can be a roller, a ball, a roller, a needle, etc., or a lubricating material (for example: POM, polytetrafluoroethylene, grease). The embodiment of the present utility model does not make specific limitations on this, and users can choose different second sliding members 360 according to different application scenarios.

[0075] Please continue to see Figure 1 and Figure 4 As shown, according to another embodiment of the present invention, the clamping jaw 330 has a sliding groove 331 on one side close to the push plate 320, and the push plate 320 has a slider 321 at the end away from the clamping mechanism 500. The slider 321 is arranged opposite to the sliding groove 331 and is slidably connected.

[0076] Specifically, the shape of the slide groove 331 can be constructed as an inclined linear groove, and the slide grooves 331 of the two clamping jaws 330 can be arranged 180° rotationally symmetrically. One end of the slide groove 331 abuts the slider 321 in the initial position, and the other end of the slide groove 331 can be arranged near the limit block 340. In this way, the push plate 320 can slide in the slide groove 331 along the axial direction of the shell 100 through the slider 321, and the limit block 340 can limit the sliding distance of the slider 321, so that the axial sliding of the push plate 320 can be converted into the closing and opening action of the clamping jaw 330, and the opening degree of the clamping jaw 330 can be controlled.

[0077] It should be noted that the initial position may be the position of the slider 321 when the clamping mechanism 500 has not yet been activated.

[0078] Furthermore, the shape of the slider 321 can be configured as a rectangle with rollers (indicated in the figure) on both sides. It should be noted that the shape of the rollers should be slightly smaller than the shape of the slide groove 331 of the clamping jaw 330. This configuration facilitates the installation of the rollers within the slide groove 331 of the clamping jaw 330, and allows the rollers to slide within the slide groove 331 of the clamping jaw 330 along the axial direction of the housing 100. The slider 321 can be fixedly connected to the push plate 320 by welding, riveting, threading, etc. The push plate 320 can slide within the slide groove 331 along the axial direction of the housing 100 via the rollers of the slider 321. The clamping mechanism 500 drives the push plate 320 to move in the axial direction of the housing 100. The push plate 320 controls the opening and closing of the clamping jaw 330 by sliding the slider 321 within the slide groove 331.

[0079] The material of the roller can be a non-metallic material, such as rubber. Rubber has excellent properties such as shock absorption, vibration reduction, low noise, and low friction. Such a setting can improve the stability of the clamping mechanism 300, reduce the noise during the operation of the electric gripper 10, and improve the practicality of the electric gripper 10.

[0080] Please continue to see Figure 1-Figure 5 As shown, according to an optional embodiment of the present invention, the clamping mechanism 300 also includes: a bearing 370; the bearing 370 is arranged between the clamping jaw seat 310 and the housing 100, and the outer ring 371 of the bearing 370 is fixedly connected to the housing 100, and the inner ring 372 of the bearing 370 is fixedly connected to the clamping jaw seat 310.

[0081] Specifically, the outer ring 371 of the bearing 370 can be fixedly connected to the housing 100 via a threaded connection, a bearing seat (not shown), or other methods. The inner ring 372 of the bearing 370 can be fixedly connected to the clamping jaw seat 310 of the clamping jaw mechanism 300 via a coaxial connection. With this arrangement, the bearing 370 ensures that the clamping jaw seat 310 can rotate relative to the housing 100 while being supported by the housing 100, thereby enabling rotation of the electric gripper 10. The use of the bearing 370 can reduce friction and wear during the rotation of the clamping jaw mechanism 300, thereby extending the service life of the electric gripper 10 and simultaneously improving its operating efficiency and reliability.

[0082] Please continue to see Figure 1-Figure 5 As shown, according to a further embodiment of the present invention, the clamping mechanism 300 further includes an elastic member 380 ; the elastic member 380 abuts between the bearing 370 and the housing 100 .

[0083] Specifically, the elastic member 380 may be a wave spring, with one side of the elastic member 380 abutting against the bearing 370 and the other side abutting against the interior of the housing 100. The elastic member 380 can be used to eliminate play in the bearing 370, making the rotational motion of the electric gripper 10 smoother and thereby improving the stability of the electric gripper 10. The elastic member 380 can absorb and disperse the impact and vibration generated by the bearing 370 during operation through its elastic deformation. This arrangement can extend the service life of the bearing 370 and the housing 100, reduce mechanical damage caused by vibration, and thereby improve the service life of the electric gripper 10.

[0084] Please continue to see Figure 4 and Figure 7 As shown, the electric gripper 10 provided according to an embodiment of the present invention includes: a shell 100, the shell 100 has a accommodating cavity 110; and includes the clamping mechanism 300 in the above embodiment, the clamping mechanism 300 is located at one end of the shell 100, wherein the specific structure and working principle of the clamping mechanism 300 have been explained in detail in the above embodiment and will not be repeated here; a rotating mechanism 200, the rotating mechanism 200 is arranged in the accommodating cavity 110, and the rotating mechanism 200 is transmission-connected to the clamping mechanism 300; a clamping mechanism 500, the clamping mechanism 500 is arranged in the accommodating cavity 110, and the clamping mechanism 500 is connected to the clamping mechanism 300.

[0085] Specifically, the shape of the housing 100 can be cylindrical or rectangular, and this is not specifically limited in the embodiments of the present invention. The structural material of the housing 100 can be a metal material, for example, an aluminum alloy, which has high strength and good processability, thereby effectively improving the overall strength of the housing 100 and significantly increasing the service life of the electric gripper 10. The interior of the housing 100 can be provided with a receiving cavity 110, which can be constructed as a cylindrical cavity or a rectangular cavity, and this is not specifically limited in the embodiments of the present invention.

[0086] Furthermore, the rotating mechanism 200 can be fixedly disposed within the accommodating chamber 110, and the main shaft of the rotating mechanism 200 can rotate relative to the accommodating chamber 110. The clamping mechanism 300 is disposed at one end of the housing 100, and the clamping seat 310 of the clamping mechanism 300 can be fixedly connected to the end of the main shaft away from the magnetic member by welding, threading, or the like. In this manner, the rotating mechanism 200 can achieve rotational movement by driving the clamping mechanism 300 via the main shaft.

[0087] It should be noted that the clamping mechanism 500 can be fixedly disposed within the accommodating cavity 110, and the hollow rack of the clamping mechanism 500 can move axially relative to the housing 100. The clamping mechanism 300 is disposed on one side of the housing 100, and the clamping jaw 330 and push plate 320 of the clamping mechanism 300 can be fixedly connected to the end of the hollow rack facing away from the rotating shaft via a transmission bearing 370. In this arrangement, the clamping mechanism 500 can drive the clamping mechanism 300 through the axial sliding of the hollow rack to achieve the opening and closing action of the clamping mechanism 300.
