DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] Embodiment 1:

[0020] Please refer to the attached Figure 1-2The utility model provides a clamping manipulator, including a mounting top plate 1, which can be used to mount the manipulator on a mechanical arm. The mechanical arm is a well-known technology for those skilled in the art, and will not be described in detail. A clamping assembly is fixed to the bottom of the mounting top plate 1, and two clamping plates 10 are fixed to the clamping assembly. Both clamping plates 10 are provided with anti-dropping assemblies.

[0021] The clamping assembly is a horizontally arranged mobile base 2, the top of the mobile base 2 is fixed to the bottom of the mounting top plate 1, a servo motor 3 is fixed to the end of the mobile base 2, the output shaft of the servo motor 3 passes through the end of the mobile base 2, and the output shaft of the servo motor 3 is fixed with a bidirectional screw rod 4, the end of the bidirectional screw rod 4 is rotatably connected to the side of the inner wall of the mobile base 2, so when the servo motor 3 is running, it can drive the bidirectional screw rod 4 to rotate forward and reversely in the mobile base 2, and the two sides of the surface of the bidirectional screw rod 4 are symmetrically threaded with threaded sleeves 5, and the bottoms of the two threaded sleeves 5 are vertically fixed with limit plates 6, and the bottom of the mobile base 2 A strip-shaped limiting hole 7 is opened horizontally, and the bottom ends of the two limiting plates 6 vertically pass through the strip-shaped limiting hole 7, and the surfaces of the limiting plates 6 are in contact with the hole walls of the strip-shaped limiting hole 7. A movable plate 8 is fixed to the bottom ends of the two limiting plates 6. Specifically, under the common limiting action of the limiting plates 6 and the strip-shaped limiting holes 7, when the servo motor 13 drives the bidirectional screw rod 4 to rotate forward and reversely, the two threaded sleeves 5 symmetrically threadedly connected to the surface of the bidirectional screw rod 4 can be converted from forward and reverse rotational motion to linear reciprocating motion, that is, the two threaded sleeves 5 can drive the two movable plates 8 to move toward or in the opposite direction through the two limiting plates 6;

[0022] The bottom of the two movable plates 8 can be detachably mounted with a connecting plate 9. It should be noted that the connecting plate 9 and the movable plate 8 can be detachably mounted by bolt fixing, and the tops of the two clamping plates 10 are respectively fixed to the bottoms of the two connecting plates 9, that is, when the two movable plates 8 move toward each other, the connecting plate 9 can drive the two clamping plates 10 to move toward each other synchronously, thereby realizing the function of clamping objects, and it is convenient for technicians in this field to disassemble and assemble the clamping plates 10, thereby facilitating replacement and maintenance;

[0023] The anti-drop assembly is composed of two baffles 11, which are rotatably connected to the bottom ends of the two clamping plates 10 respectively. A fixing plate 12 is symmetrically fixed on the back-to-back sides of the two clamping plates 10. An electric push rod 13 is vertically fixed to the bottom of the fixing plate 12. It should be noted that the electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The bottom end of the output shaft of the electric push rod 13 is rotatably connected to a connecting rod 14. The end of the connecting rod 14 away from the electric push rod 13 is rotatably connected to the surface of the baffle 11. Specifically, when the electric push rod 13 is running, the baffle 11 can be driven to rotate at the bottom end of the clamping plate 10 through the connecting rod 14. When the two baffles 11 rotate toward each other, they can rotate to the bottom of the article clamped by the clamping plate 10, thereby effectively blocking the clamped article, thereby effectively preventing the article from falling during the clamping process, and can well ensure the stability of the article during the clamping process.

[0024] It should be noted that the manipulator is electrically connected to an external main controller and 220V AC power, and the main controller can be a computer or other existing technical equipment for control.

[0025] The use process of the utility model is as follows: the technicians in this field operate the servo motor 3 through the main controller to control the two clamps 10 to move towards each other to clamp the object first, and then operate the electric push rod 13 through the main controller to control the two baffles 11 to rotate towards each other to the bottom of the object clamped by the clamp 10, so as to effectively block the clamped object, thereby effectively preventing the object from falling during the clamping process, and can well ensure the stability of the object during the clamping process.

Specifically, when the two servo motors 16 are running, the rotating rods 17 can be controlled to rotate in the forward and reverse directions. When the two rotating rods 17 rotate toward each other, the two baffles 18 can be driven to rotate to the bottom of the items clamped by the clamping plates 10, so as to effectively block the clamped items, thereby effectively preventing the items from falling during the clamping process, and ensuring the stability of the items during the clamping process.

[0028] It should be noted that the manipulator is electrically connected to an external main controller and 220V AC power, and the main controller can be a computer or other existing technical equipment for control.

[0029] The use process of the utility model is as follows: the technicians in this field operate the servo motor 13 through the main controller to control the two clamps 10 to move towards each other to clamp the items first. After the items are clamped, the main controller operates the servo motor 16 to control the two baffles 18 to rotate towards each other to the bottom of the items clamped by the clamps 10, so as to effectively block the clamped items, thereby effectively preventing the items from falling during the clamping process, and ensuring the stability of the items during the clamping process.
