Description

Technical Field

[0001] This utility model belongs to the field of automated assembly technology, specifically, it relates to a gripper that can hold materials and can be positioned and rotated. Background Technology

[0002] In many fields such as industrial production and logistics transportation, it is often necessary to grasp, move and position materials. Grippers are usually used to achieve the linkage of two or more grippers through cylinders, electric cylinders, hydraulic cylinders or other linkage mechanisms to grasp materials.

[0003] A search revealed that CN211916878U discloses a gripper that can hold materials and rotate in a position. This gripper can meet the purpose of positioning and rotating products on ordinary equipment and can hold a wide range of materials.

[0004] However, the gripper can only rotate the object it is gripping, and cannot change the angle of the object. When it is necessary to change the angle of the object, the entire robotic arm needs to rotate, which results in a large space for the movement trajectory of the entire robotic arm.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To address the technical problem that the gripper can only rotate the object it grasps, but cannot change the angle of the object, and that changing the angle of the object requires the entire robotic arm to rotate, resulting in a large spatial variation in the robotic arm's movement trajectory, the basic concept of this invention is as follows:

[0007] A gripper clamp capable of holding materials and rotating in a position, including a mounting frame;

[0008] An adjustment mechanism is provided on the mounting plate disposed inside the mounting frame, and an auxiliary adjustment mechanism is provided on one side of the adjustment mechanism. The adjustment mechanism includes a fixing plate fixedly connected to the outer wall of the mounting frame.

[0009] An electric telescopic rod is fixedly connected to the inner outer wall of the fixed plate. A movable block is fixedly connected to the output end of the electric telescopic rod. A hinge seat is movably disposed on the movable block. A limit groove is formed on the outer wall of the mounting plate. A slider is slidably disposed inside the limit groove. The outer wall of the slider is fixedly connected to the outer wall of one side of the hinge seat. A rotating column is fixedly connected to the outer wall of the mounting plate. A first torsion spring is fixedly connected to the end of the rotating column away from the outer wall of the mounting plate. A rotating groove is formed on the inner wall of the mounting frame. The end of the first torsion spring away from the outer wall of the mounting plate is fixedly connected to the inner wall of the rotating groove.

[0010] In a preferred embodiment of this utility model, the auxiliary adjustment mechanism includes a guide rod cylinder fixedly connected to the outer wall of the mounting plate. A force-applying block is fixedly connected to the output end of the guide rod cylinder. A rotating hole is opened on one side of the outer wall of the mounting plate. A second torsion spring is fixedly connected to the inner wall of the rotating hole. A rotating rod is fixedly connected to the end of the second torsion spring away from the inner wall of the rotating hole. A gripper is fixedly connected to the outer wall of the rotating rod. A roller is fixedly connected to the bottom outer wall of the gripper. A clamping sleeve is rotatably provided on the outer wall of the mounting plate. A motor is fixedly connected to one side of the outer wall of the mounting plate. The output end of the motor is fixedly connected to the outer wall of the clamping sleeve.

[0011] In a preferred embodiment of this utility model, there are two rotating columns and two first torsion springs, which are distributed in a left-right symmetrical structure on the mounting frame and the mounting plate.

[0012] In a preferred embodiment of this utility model, the inner wall of the rotating groove opened in the inner wall of the mounting frame is properly fitted to the outer wall of the rotating column.

[0013] In a preferred embodiment of this utility model, the inner wall of the limiting groove is properly fitted to the outer wall of the slider.

[0014] In a preferred embodiment of this utility model, there are two rotating rods and two second torsion springs, and the rotating rods and the second torsion springs are distributed on the mounting plate in a left-right symmetrical structure.

[0015] In a preferred embodiment of this utility model, the bottom end of the jacket is provided with a feeding slot, and the jacket is made of flexible rubber.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] In this invention, when the angle of the clamped object needs to be adjusted, the electric telescopic rod can be activated. Its output end will drive the movable block to move forward. The movement of the movable block will drive the hinge seat to move, and the hinge seat will apply force to the mounting plate. Then, the mounting plate will drive the rotating column to rotate, and the rotation of the rotating column will drive the first torsion spring to rotate. At this time, the hinge seat will push the slider to slide on the inner wall of the limiting groove. As the output end of the electric telescopic rod continues to push, the movable block will rotate with the hinge seat. In this way, the mounting plate can be movably connected with the output end of the electric telescopic rod as the angle of the mounting plate rotates. Thus, the angle of the clamped object can be adjusted by rotating the mounting plate, which eliminates the need for the robotic arm to rotate over a large range, making it more practical.

[0018] In this invention, when clamping is required, the object to be gripped is first placed in the clamping sleeve. Then, the guide rod cylinder is activated, and its output end will drive the force-applying block to move downward. At this time, the inclined edge at the bottom of the force-applying block will gradually disengage from the gripper, so that the top of the gripper rotates and adheres to the outer walls of both sides of the force-applying block through the rebound of the second torsion spring. In this way, the bottom of the gripper will form a clamping effect. Then, the clamping sleeve is deformed to clamp the object. When it is necessary to rotate the object, the motor can be started, and its output end will drive the clamping sleeve to rotate. The rotation of the clamping sleeve will drive the object to rotate, thereby adjusting the angle of the object itself, which is convenient for subsequent processing operations.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figures 1 to 5As shown, a gripper clamp capable of holding materials and rotating in a position includes a mounting frame 1, a mounting plate 2 disposed inside the mounting frame 1, an adjustment mechanism 31 disposed on the mounting plate 2, and an auxiliary adjustment mechanism 32 disposed on one side of the adjustment mechanism 31. The adjustment mechanism 31 includes a fixed plate 311 fixedly connected to the outer wall of the mounting frame 1, an electric telescopic rod 312 fixedly connected to the inner outer wall of the fixed plate 311, a movable block 313 fixedly connected to the output end of the electric telescopic rod 312, a hinge seat 314 movably disposed on the movable block 313, a limiting groove 316 formed on the outer wall of the mounting plate 2, a slider 315 slidably disposed inside the limiting groove 316, the outer wall of the slider 315 fixedly connected to one side of the outer wall of the hinge seat 314, a rotating column 317 fixedly connected to the outer wall of the mounting plate 2, a first torsion spring 318 fixedly connected to the end of the rotating column 317 away from the outer wall of the mounting plate 2, a rotating groove formed on the inner wall of the mounting frame 1, and the end of the first torsion spring 318 away from the outer wall of the mounting plate 2 fixedly connected to the inner wall of the rotating groove.

[0029] Furthermore, there are two rotating columns 317 and two first torsion springs 318. The rotating columns 317 and the first torsion springs 318 are distributed symmetrically on the mounting frame 1 and the mounting plate 2, respectively, so as to provide uniform support to the left and right sides of the mounting plate 2, thereby further improving the stability of the mounting plate 2 during rotation.

[0030] Furthermore, the inner wall of the rotating groove opened on the inner wall of the mounting frame 1 is fitted to the outer wall of the rotating column 317, thereby ensuring the tight fit between the rotating column 317 and the inner wall of the rotating groove, thus improving the stability of the rotating column 317 during rotation.

[0031] Furthermore, the inner wall of the limiting groove 316 fits snugly against the outer wall of the slider 315, thereby ensuring a tight fit between the outer wall of the slider 315 and the inner wall of the limiting groove 316, thus improving the stability of the slider 315 during movement and ensuring the stability of the object being grasped.

[0032] The auxiliary adjustment mechanism 32 includes a guide rod cylinder 321 fixedly connected to the outer wall of the mounting plate 2. A force-applying block 322 is fixedly connected to the output end of the guide rod cylinder 321. A rotating hole is opened on one side of the outer wall of the mounting plate 2. A second torsion spring 323 is fixedly connected to the inner wall of the rotating hole. A rotating rod 324 is fixedly connected to the end of the second torsion spring 323 away from the inner wall of the rotating hole. A gripper 325 is fixedly connected to the outer wall of the rotating rod 324. A roller 326 is fixedly connected to the bottom outer wall of the gripper 325. A sleeve 327 is rotatably provided on the outer wall of the mounting plate 2. A motor 328 is fixedly connected to one side of the outer wall of the mounting plate 2. The output end of the motor 328 is fixedly connected to the outer wall of the sleeve 327.

[0033] Furthermore, there are two rotating rods 324 and two second torsion springs 323. The rotating rods 324 and the second torsion springs 323 are distributed on the mounting plate 2 in a left-right symmetrical structure, so as to support the left and right grippers 325 and ensure that the grippers 325 on both sides can rotate and clamp synchronously.

[0034] Furthermore, the bottom of the sleeve 327 is provided with a feeding slot. The sleeve 327 is made of flexible rubber. By using the rubber material, it is possible to ensure that the sleeve 327 can deform during the squeezing process, and then the deformation of the sleeve 327 can be used to clamp the object being grasped.

[0035] The implementation principle of the gripper clamp capable of holding materials and rotating in a position according to this embodiment is as follows: When it is necessary to adjust the angle of the object being gripped, the electric telescopic rod 312 can be activated. Its output end will drive the movable block 313 to move forward. The movement of the movable block 313 will drive the hinge seat 314 to move. At this time, the hinge seat 314 will apply force to the mounting plate 2. Then, the mounting plate 2 will drive the rotating column 317 to rotate. The rotation of the rotating column 317 will drive the first torsion spring 318 to rotate. At this time, the hinge seat 314 will push the slider 315 to slide on the inner wall of the limiting groove 316. As the output end of the electric telescopic rod 312 continues to push, the movable block 313 will rotate with the hinge seat 314. In this way, as the angle of the mounting plate 2 rotates, it can be movably connected with the output end of the electric telescopic rod 312. Thus, by rotating the mounting plate 2, the angle of the object being gripped can be adjusted. This eliminates the need for the robotic arm to rotate over a large range, which is more practical.

[0036] When clamping is required, the object to be gripped is first placed in the clamping sleeve 327. Then, the guide rod cylinder 321 is activated, and its output end will drive the force application block 322 to move downward. At this time, the inclined edge at the bottom of the force application block 322 will gradually disengage from the gripper 325, so that the top of the gripper 325 is rotated and attached to the outer walls of both sides of the force application block 322 by the rebound of the second torsion spring 323. In this way, the bottom of the gripper 325 will form a clamping effect. Then, the clamping sleeve 327 is clamped and deformed. In this way, the object to be gripped can be clamped by the deformation of the clamping sleeve 327. When it is necessary to rotate the object to be gripped, the motor 328 can be activated, and its output end can drive the clamping sleeve 327 to rotate. The rotation of the clamping sleeve 327 can drive the object to rotate, thereby adjusting the angle of the object to be gripped, which is convenient for subsequent processing operations.
