[0001] This utility model relates to the field of robotic arm technology, specifically to a non-slip and wear-resistant mechanical gripper. Background Technology

[0002] Machinery manufacturing refers to the industrial sector engaged in the production of various power machinery and other mechanical equipment. During the machinery manufacturing process, it is often necessary to clamp and move mechanical parts. Currently, most of this is done using mechanical grippers. These grippers play a crucial role in modern manufacturing, replacing workers in performing many heavy and tedious tasks.

[0003] For example, utility model CN218138138U2 discloses a wear-resistant and anti-slip multi-claw manipulator, including a disc, a motor fixed on the disc by a bracket, a threaded rod fixed on the motor shaft by a coupling, a bearing with interference fit to the threaded rod fixed on the disc, a threaded sleeve threaded on the threaded rod, a connecting rod hinged to the threaded sleeve, a connecting plate hinged to the other end of the connecting rod, a limit groove provided on the disc, a limit block fixed on the disc that slides with the limit groove, a connecting block fixed on the limit block, and claws mounted on the connecting block. This utility model, through the movement of the claws in four directions, can achieve multi-claw gripping of box-shaped objects, thereby avoiding slippage and gripping failure.

[0004] In the process of developing this application, the following problems were found in the technology: the claw tips are prone to wear after long-term use, which affects the use and makes it inconvenient to replace, resulting in poor flexibility of the claw tips.

[0005] To address these shortcomings, a non-slip and wear-resistant mechanical gripper is proposed, which upgrades and modifies the existing device. Utility Model Content

[0006] The purpose of this utility model is to provide a non-slip and wear-resistant mechanical gripper to solve the problems in the background technology.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A non-slip, wear-resistant mechanical gripper includes a robotic arm. A disk is fixedly connected to the lower end of the robotic arm. A motor is fixedly mounted on the inner wall of the disk. A threaded rod is fixedly mounted on the output shaft of the motor. The end of the threaded rod away from the motor is rotatably connected to the inner wall of the disk via a bearing. A threaded block is threadedly connected to the outer end of the threaded rod. A transmission rod is rotatably connected to the outer end of the threaded block. A connecting block is rotatably connected to the lower end of the transmission rod. A rotating rod is fixedly connected to the lower end of the connecting block. The upper end of the rotating rod is rotatably connected to the inner wall of the disk. The lower end of the rotating rod... A disc extends outwards and is fitted with grippers. A mounting block is fixedly connected to the lower end of the grippers. A gripper head is fitted onto the outer end of the mounting block. Rubber anti-slip pads are fixedly installed on the gripper head and the grippers on the side closest to each other. A concave block is rotatably connected to the lower side of the outer end of the grippers. A gear one is fixedly installed at one end of the concave block. A gear two is meshed with the outer end of gear one. A screw rod is fixedly installed at the upper end of gear two. The outer side of the screw rod near gear two is rotatably connected to the inner wall of the grippers through a bearing. The upper end of the screw rod is threadedly connected to the inner wall of the rotating rod.

[0009] Furthermore, a limiting rod is slidably connected to the inner wall of the threaded block, and both ends of the limiting rod are fixedly installed to the inner wall of the disc.

[0010] Furthermore, a limiting block is fixedly connected to the outer end of the rotating rod, and a limiting groove is provided on the inner wall of the gripper for the outer end of the limiting block to slide.

[0011] Furthermore, a concave fixing rod is slidably connected to the inner wall of the gripper head, and a fixing hole is provided on the inner wall of the mounting block for the outer end of the concave fixing rod to be slidably connected. A pull rod is fixedly connected to the end of the concave fixing rod away from the mounting block, and a fixing plate is slidably connected to the outer end of the pull rod. One end of the fixing plate is fixedly connected to the outer end of the gripper head, and a pull ring is rotatably connected to one end of the pull rod.

[0012] Furthermore, a spring is provided at the outer end of the pull rod, one end of the spring is fixedly installed to the outer end of the concave fixing rod, and the other end of the spring is fixedly installed to the inner wall of the fixing plate.

[0013] Furthermore, the inner wall of the gripper head is provided with a connecting groove that matches one end of the concave fixing rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a starting motor to drive the threaded rod to rotate, which in turn moves the connecting block at one end of the transmission rod, causing the rotating rod to open or close the gripper, facilitating the fixing of objects. The inner rubber anti-slip pad increases the friction between the gripper and the object, improving the gripper's anti-slip effect. Simultaneously, by inserting a tool into the concave block and rotating it, the first gear drives the screw rod at the upper end of the second gear to rotate, causing the rotating rod to move between the gripper and the gripper, increasing the gripper's length and improving the stability of gripping objects.

[0016] 2. This utility model moves by pulling the pull ring outward, causing the pull rod to move the concave fixing rod away from the fixing hole, which makes it easy to remove the gripper head from the mounting block and replace the gripper head. Conversely, the spring makes it easy to install the new gripper head. Attached Figure Description

[0027] like Figures 1 to 5 As shown, a non-slip and wear-resistant mechanical gripper includes a mechanical arm 10. A disk 1 is fixedly connected to the lower end of the mechanical arm 10. A motor 16 is fixedly installed on the inner wall of the disk 1. A threaded rod 165 is fixedly installed on the output shaft of the motor 16. The end of the threaded rod 165 away from the motor 16 is rotatably connected to the inner wall of the disk 1 through a bearing. A threaded block 161 is threadedly connected to the outer end of the threaded rod 165. A transmission rod 162 is rotatably connected to the outer end of the threaded block 161. A connecting block 163 is rotatably connected to the lower end of the transmission rod 162. A rotating rod 111 is fixedly connected to the lower end of the connecting block 163. The upper end of the rotating rod 111 is rotatably connected to the inner wall of the disk 1. A gripper 11 extends out of the disk 1 from the lower end of the rotating rod 111. A mounting block 174 is fixedly connected to the lower end of the gripper 11. A gripper head 12 is sleeved on the outer end of the mounting block 174. A rubber anti-slip pad 112 is fixedly installed on the side where the gripper head 12 and the gripper 11 are close to each other.

[0028] Specifically, by starting the motor 16, the threaded rod 165 is rotated, which causes the threaded block 161 to move the connecting block 163 at one end of the transmission rod 162, so that the rotating rod 111 drives the gripper 11 to open or close, which facilitates fixing the object.

[0029] like Figure 1 and Figure 2As shown, a limiting rod 164 is slidably connected to the inner wall of the threaded block 161, and the two ends of the limiting rod 164 are fixedly installed to the inner wall of the disc 1; specifically, this facilitates the stable movement of the threaded block 161.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, a concave fixing rod 17 is slidably connected to the inner wall of the gripper head 12. A fixing hole 172 is provided on the inner wall of the mounting block 174 for the outer end of the concave fixing rod 17 to be slidably connected. A pull rod 15 is fixedly connected to the end of the concave fixing rod 17 away from the mounting block 174. A fixing plate 13 is slidably connected to the outer end of the pull rod 15. One end of the fixing plate 13 is fixedly connected to the outer end of the gripper head 12. A pull ring 14 is rotatably connected to one end of the pull rod 15. A spring 171 is provided on the outer end of the pull rod 15. One end of the spring 171 is fixedly installed to the outer end of the concave fixing rod 17. The other end of the spring 171 is fixedly installed to the inner wall of the fixing plate 13. A connecting groove 173 matching one end of the concave fixing rod 17 is provided on the inner wall of the gripper head 12.

[0031] Specifically, by pulling the pull ring 14 outward, the pull rod 15 moves the concave fixing rod 17 away from the fixing hole 172, making it easy to remove the gripper head 12 from the mounting block 174 and replace the gripper head 12. Conversely, the action of the spring 171 makes it easy to install the new gripper head 12.

[0032] like Figure 1 and Figure 5 As shown, a concave block 19 is rotatably connected to the lower outer end of the gripper 11. A gear 191 is fixedly installed at one end of the concave block 19. A gear 192 is meshed with the outer end of the gear 191. A screw rod 195 is fixedly installed at the upper end of the gear 192. The outer side of the screw rod 195 near the gear 192 is rotatably connected to the inner wall of the gripper 11 through a bearing. The upper end of the screw rod 195 is threadedly connected to the inner wall of the rotating rod 111. Specifically, by inserting a tool into the concave block 19 and rotating it, the gear 191 drives the screw rod 195 at the upper end of the gear 192 to rotate, causing the rotating rod 111 to move between the gripper 11 and the gripper 11, increasing the length of the gripper 11 and improving the stability of gripping objects.

[0033] like Figure 1 and Figure 5 As shown, the outer end of the rotating rod 111 is fixedly connected to a limiting block 194, and the inner wall of the gripper 11 is provided with a limiting groove 193 for the outer end of the limiting block 194 to slide; specifically, this facilitates the stable movement of the rotating rod 111.

[0034] In summary: When the equipment grips an object, the starting motor 16 drives the threaded rod 165 to rotate, causing the threaded block 161 to move the connecting block 163 at one end of the transmission rod 162, which in turn causes the rotating rod 111 to open or close the gripper 11, facilitating the fixing of the object. The inner rubber anti-slip pad 112 increases the friction between the gripper 11 and the object. By inserting a tool into the concave block 19 and rotating it, the gear one 191 drives the screw rod 195 at the upper end of the gear two 192 to rotate, causing the rotating rod 111 to move between the gripper 11 and the gripper 11, increasing the length of the gripper 11 and enabling the gripper 11 to stably grip the object.

[0035] Pulling the pull ring 14 moves the pull rod 15, causing the concave fixing rod 17 to move away from the fixing hole 172, making it easier to remove the gripper head 12 from the mounting block 174. Conversely, by putting the new gripper head 12 on the mounting block 174, the concave fixing rod 17 is reconnected to the fixing hole 172 by the action of the spring 171, making it easier to fix and install the gripper head 12.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
