Technical Field

[0001] The utility model belongs to the technical field of manipulator clamps, in particular to a manipulator clamp with a protection function. Background Art

[0002] A robot is a mechanical device that can imitate certain movements of human hands and arms. A clamp is often installed on the robot to fix the processing object. The robot greatly saves manpower and improves work efficiency. It is widely used in mechanical manufacturing, electronics and industry. For example, when processing workpieces, the workpiece is clamped and fixed by a commonly used robot clamp.

[0003] However, the existing robotic clamps on the market are highly dangerous during the clamping process and lack protective limit mechanisms. The workpiece is generally clamped and fixed by an electric control clamp. When an emergency occurs such as a power outage or circuit problem, the robotic clamp is prone to loosening, which can easily cause the workpiece to separate from the clamp, causing the workpiece to fall and be damaged. This is not conducive to the protection of the workpiece and is also easy to injure workers, posing certain safety hazards.

[0004] Therefore, a robot clamp with a protective function is proposed to solve the problems raised in the background art. Utility Model Content

[0005] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a manipulator clamp with a protective function, which solves the problem that the existing manipulator clamp uses an electric control clamp to clamp and fix the workpiece, which is highly dangerous and lacks a protective limit mechanism. When an emergency such as a power outage or circuit problem occurs, it is easy for the workpiece to separate from the clamp, causing the workpiece to fall.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manipulator clamp with a protective function, comprising a manipulator arm mounting frame, wherein two clamping plates for clamping the workpiece are symmetrically arranged at the bottom of the manipulator arm mounting frame, and two lifting plates are hinged at the bottom of the two clamping plates, and the surfaces of the two lifting plates are in contact with the workpiece, and a clamping plate and an adjustment mechanism are arranged inside one of the lifting plates, and the adjustment mechanism is used to adjust the position of the lifting plate.

[0008] Preferably, the adjustment mechanism comprises an adjustment block, and a driving assembly is provided at the bottom of the adjustment block.

[0009] Preferably, the adjusting block is an irregular triangular block, and a groove is provided on the surface of the adjusting block, and the groove is engaged with the protrusion.

[0010] Preferably, the driving assembly includes a worm gear, which coincides with the central axis of the adjusting block, and the bottom of the worm gear is rotatably connected to the inside of the lifting plate. A worm is engaged on the surface of the worm gear, and both ends of the worm are fixedly connected to a connecting rod, which passes through the side of the lifting plate and is rotatably connected to the side of the lifting plate. The end of the connecting rod located outside the lifting plate is fixedly connected to a rotating block, and a plurality of slots suitable for human hands are provided on the surface of the rotating block.

[0011] Preferably, two symmetrical sides of the robotic arm mounting frame are fixedly connected with fixing rods, and both ends of the fixing rods are fixedly connected with limiting plates.

[0012] Preferably, a fixing rope is sleeved on the fixing rod, and hooks are fixedly connected to both symmetrical sides of the lifting plate, and the surface of the hook is hooked with the end of the fixing rope away from the fixing rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model realizes the lifting and limiting of the clamped workpiece through the coordinated use of a lifting plate, a clamping plate and an adjusting mechanism.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, the utility model provides a manipulator clamp with a protective function, including a manipulator mounting frame 1, two clamping plates 11 for clamping a workpiece are symmetrically arranged at the bottom of the manipulator mounting frame 1, and the bottoms of the two clamping plates 11 are hinged to two lifting plates 2, and the surfaces of the two lifting plates 2 are in contact with the workpiece. A clamping plate 3 and an adjustment mechanism 4 are arranged inside one of the lifting plates 2, and the adjustment mechanism 4 is used to adjust the position of the lifting plate 2. A protrusion 31 is fixedly connected to one side of the clamping plate 3, and the protrusion 31 slides inside one of the lifting plates 2. The adjustment mechanism 4 includes an adjustment block 41, and a driving assembly 42 is arranged at the bottom of the adjustment block 41. The adjustment block 41 is a triangular irregular block, and a groove 411 is opened on the surface of the adjustment block 41, and the groove 411 is clamped with the protrusion 31.

[0024] The above scheme is adopted: when using the clamping plate 11 to clamp the workpiece, in order to avoid the clamping plate 11 loosening due to power outage or circuit problem, causing the workpiece to separate from the clamping plate 11, and then causing the workpiece to fall, after clamping the workpiece, the lifting plate 2 can be rotated to a position perpendicular to the clamping plate 11 to lift the workpiece, and the driving component 42 is used to drive the adjustment block 41 to rotate, so that the protrusion of the adjustment block 41 contacts the protrusion of the clamping plate 3, so that the clamping plate 3 slides along the inner wall of the lifting plate 2, and then approaches the other lifting plate 2, and is slidably inserted into the other lifting plate 2, so that the two lifting plates 2 are clamped and fixed, and the lifting plate 2 and the clamping plate 3 form a closed surface, so as to lift the workpiece and avoid the problem of the workpiece falling and injuring people during the clamping process.

[0025] like Figures 1 to 6As shown, the driving assembly 42 includes a worm gear 421, which coincides with the central axis of the adjusting block 41. The bottom of the worm gear 421 is rotatably connected to the inside of the lifting plate 2. The surface of the worm gear 421 is engaged with a worm 422. Both ends of the worm 422 are fixedly connected to a connecting rod 423. The connecting rod 423 passes through the side of the lifting plate 2 and is rotatably connected to the side of the lifting plate 2. The end of the connecting rod 423 located outside the lifting plate 2 is fixedly connected to a rotating block 424. The surface of the rotating block 424 is provided with a plurality of slots suitable for human hands.

[0026] The above scheme is adopted: by utilizing the driving assembly 42, manually rotating the rotating block 424 drives the connecting rod 423 to rotate, and then drives the worm 422 to rotate, so that the worm wheel 421 meshing with the worm 422 rotates, thereby driving the adjusting block 41 coaxial with the worm wheel 421 to rotate. Due to the irregular side of the adjusting block 41, when the protrusion of the adjusting block 41 abuts against the protrusion 31 on the surface of the card plate 3, it will drive the card plate 3 to slide to the side away from the protrusion 31 and be clamped inside the other lifting plate 2, so that the two lifting plates 2 are clamped and fixed. When the groove 411 of the adjusting block 41 is close to the side of the protrusion 31, the card plate 3 can be manually moved in the direction of the groove 411, so that the card plate 3 enters the lifting plate 2 on the side of the driving assembly 42, thereby facilitating the rotation and storage of the two lifting plates 2.

[0027] like Figures 1 to 6 As shown, the two symmetrical sides of the robot arm mounting frame 1 are fixedly connected with fixed rods 12, both ends of the fixed rods 12 are fixedly connected with limiting plates 121, a fixing rope 5 is sleeved on the fixed rod 12, and the two symmetrical sides of the lifting plate 2 are fixedly connected with hooks 21, and the surface of the hook 21 is hooked with the end of the fixing rope 5 away from the fixed rod 12.

[0028] The above solution is adopted: by utilizing the fixing rope 5, after use, the lifting plate 2 can be rotated to a direction parallel to the clamping plate 11, and the fixing rope 5 can be hung on the hook 21 on the lifting plate 2. Under the influence of gravity, the fixing rope 5 is in a taut state, which is convenient for fixing the lifting plate 2 and avoiding affecting the storage and clamping of workpieces.

[0029] The working principle and use process of the present invention: When using the present invention, in order to avoid the problem that the clamping plate 11 becomes loose when there is a power outage or circuit problem, causing the workpiece to separate from the clamping plate 11 and then causing the workpiece to fall, after using the clamping plate 11 to clamp the workpiece, manually rotate the rotating block 424 to drive the connecting rod 423 to rotate, thereby driving the worm 422 to rotate, so that the worm wheel 421 meshing with the worm 422 rotates, thereby driving the adjusting block 41 coaxial with the worm wheel 421 to rotate. Since the side surface of the adjusting block 41 is irregular, when the protrusion of the adjusting block 41 abuts against the protrusion 31 on the surface of the clamping plate 3, it will drive the clamping plate 3 to the side away from the protrusion 31. The two lifting plates 2 can be locked together and fixed by sliding, and the lifting plates 2 and the clamping plate 3 can form a closed surface, which is convenient for lifting the workpiece. After use, the adjusting block 41 can be rotated to make the groove 411 of the adjusting block 41 close to the side of the protrusion 31, and the clamping plate 3 can be manually moved toward the groove 411 to make the clamping plate 3 enter the lifting plate 2 on the side of the driving component 42, so as to facilitate the rotation and storage of the two lifting plates 2, and the fixing rope 5 can be hung on the hook 21 on the lifting plate 2 to achieve the fixed limit of the lifting plate 2 and the two splints 11, thereby completing the entire lifting limit operation.
