Description

Technical Field

[0001] The invention belongs to the technical field of artillery, and in particular relates to a variable charging manipulator. Background Art

[0002] Unmanned and intelligent artillery is an important development direction, and the automatic ammunition loading system is the prerequisite for unmanned and intelligent artillery. The propellant of a certain caliber artillery is composed of multiple horseshoe-shaped loading boxes. The box is soft in texture, and it is difficult to achieve automatic loading.

[0003] Currently, Chinese patent publication number CN 105492856 A discloses a gripping device for holding ammunition during gun loading. The device comprises a bracket movably mounted along the longitudinal direction of the ammunition, with claws on the bracket movably mounted in a plane perpendicular to the forward direction of the bracket. The claws are configured to be in a locked position and an unlocked position during use. In the locked position, the claws are fixed and can clamp the ammunition. In the unlocked position, the entire ammunition can pass through in its longitudinal direction. This mechanism intelligently locks and unlocks the ammunition, but cannot achieve automatic gripping and loading of the cartridge.

[0004] Chinese patent publication number CN 113295042 A discloses a large-caliber artillery explosive loading device and its operating method. By arranging the magazine and the cylinder on both sides of the gun carriage, the ammunition loading speed can be greatly accelerated, while the residual cartridges can be handled more conveniently. It has the advantages of fast loading and firing speeds, but it cannot realize the grabbing and loading of different numbers of cartridges. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, the present invention provides a variable charging manipulator. The device primarily consists of a frame, a movable splint, a fixed splint, a top plate, a forward friction wheel, a reverse friction wheel, a motor, a reversing gear, a tension spring, a timing belt, and other components. Adjusting the distance between the movable and fixed splints allows for the grabbing and installation of varying numbers of pill boxes. Once a pill box is mounted on a projectile, the friction wheel rotates, causing adjacent pill boxes to rotate in opposite directions to ensure even distribution. Furthermore, the device is compact and takes up little space. The present invention boasts a rational design, simple structure, and reliable transmission, making it suitable for use in automatic ammunition loading systems.

[0006] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0007] A variable charging manipulator comprises a frame, a movable splint, a fixed splint, a top plate, a forward friction wheel, a reverse friction wheel, a motor, a reversing gear, a tension spring and a synchronous belt;

[0008] The movable splint is connected to the lead screw through a lead screw nut and moves left and right as the lead screw rotates;

[0009] The fixed splint is fixedly connected to the frame as a whole, and the top plate is connected to the frame by screws. The top plate is divided into two parts, upper and lower, for unlocking the medicine box pressure plate during the medicine removal process;

[0010] The forward friction wheel and the reverse friction wheel are connected to the corresponding shafts through keys and sleeves; the shafts are connected to the frame through bearings and are driven to rotate by the reversing gears;

[0011] The motor is fixed on the frame, and the power output by the motor is transmitted to the corresponding shaft through the pulley and the synchronous belt.

[0012] Preferably, the variable charging manipulator realizes two actions, one is the clamping action of the clamping plate, and the other is the rotation action of the friction wheel.

[0013] Preferably, the clamping power of the movable splint is transmitted to the movable splint through the motor-pulley-synchronous belt-screw-screw nut, driving the movable splint to move left and right to realize the clamping action; the left and right movement of the movable splint realizes the clamping of different numbers of medicine boxes, thereby realizing the variable charging function.

[0014] Preferably, when the movable splint moves laterally, its upper and lower paddles drive the top plate to switch between horizontal and vertical positions. When the top plate is in the horizontal position, it can push open the medicine clamping plate on the medicine bin, and when it is in the vertical position, it cannot push open the medicine clamping plate on the medicine bin, so as to achieve the grabbing of the required number of medicine boxes.

[0015] Preferably, the rotational power of the forward friction wheel and the reverse friction wheel is transmitted to each friction wheel through the motor-pulley-synchronous belt-shaft-reversing gear, and the two adjacent friction wheels rotate in opposite directions, so that the two adjacent medicine boxes can rotate in opposite directions by a certain angle to ensure that the overall medicine boxes are evenly distributed.

[0016] The beneficial effects of the present invention are as follows:

[0017] The present invention can realize the grabbing and installation of different numbers of launch pill boxes, and after the pill boxes are installed, two adjacent pill boxes are rotated in opposite directions to ensure that the pill boxes are evenly distributed. The manipulator of the present invention has a simple and compact structure, high reliability, small size and high space utilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings and examples.

[0021] The purpose of the present invention is to design a variable charging manipulator to realize the grabbing and installation of different numbers of launch charge boxes. After the boxes are installed, the two adjacent boxes are rotated in opposite directions to ensure that the boxes are evenly distributed.

[0022] The present invention provides a variable charging manipulator, which includes a frame, a movable splint, a fixed splint, a top plate, a forward friction wheel, a reverse friction wheel, a motor, a reversing gear, a tension spring, a synchronous belt, etc.

[0023] The movable splint is connected to the screw through the screw nut and moves left and right with the rotation of the screw; the fixed splint is fixedly connected to the frame as a whole, and the top plate is connected to the frame by screws, divided into two parts, upper and lower, which are used to unlock the medicine box pressure plate during the medicine removal process;

[0024] The forward friction wheel and the reverse friction wheel are connected to the corresponding shafts through keys and sleeves. The shafts are connected to the frame through bearings and driven to rotate by reversing gears. The motor is fixed on the frame, and the power output by the motor is transmitted to the corresponding shafts through pulleys and synchronous belts.

[0025] The variable charging manipulator mainly realizes two actions, one is the clamping action of the splint, and the other is the rotation action of the friction wheel.

[0026] The clamping power of the splint is transmitted to the movable splint through the motor-pulley-synchronous belt-screw-screw nut, driving the movable splint to move left and right to achieve the clamping action. The movable splint has a large left and right movement range, which can realize the clamping of different numbers of medicine boxes, thereby realizing the variable charging function.

[0027] The rotational power of the forward friction wheel and the reverse friction wheel is transmitted to each friction wheel through the motor-pulley-synchronous belt-shaft-reversing gear. The two adjacent friction wheels rotate in opposite directions, so that the two adjacent medicine boxes can rotate in opposite directions by a certain angle to ensure that the overall medicine boxes are evenly distributed.

[0028] When the medicine boxes are installed on the projectile, the friction wheel rotates, and the friction force causes the two adjacent medicine boxes to rotate in opposite directions to ensure that the medicine boxes are evenly distributed.

[0029] Example:

[0030] See Figure 1 The variable charging manipulator consists of a frame 1, a movable clamp 2, a fixed clamp 3, a top plate 4, a forward friction wheel 5, a reverse friction wheel 6, a motor 7, a reversing gear 8, a tension spring 9, a synchronous belt 10, etc.

[0031] First, the medicine-taking action is performed. The variable charging manipulator is driven to the medicine bin by the motion mechanism. When the variable charging manipulator approaches the medicine bin, its upper and lower top plates push open the upper and lower pressure plates that clamp the medicine box on the medicine bin. At this time, the medicine box is in an unlocked state, and then the movable splint performs the clamping action to clamp the required medicine box. The variable charging manipulator moves backward to complete the medicine-taking action.

[0032] The variable charging manipulator is driven by the motion mechanism to the charging location and fixes the medicine box to a fixed position. At this time, the movable splint is loosened, and the forward friction wheel and reverse friction wheel rotate to rotate the adjacent medicine boxes by a certain angle so that the medicine boxes are evenly distributed. The variable charging manipulator moves backward to complete the charging action.
