Description

Technical Field

[0001] This utility model relates to the technical field of aluminum ingots, and in particular to an aluminum ingot stacking mechanism. Background Technology

[0002] Aluminum is the world's second largest non-ferrous metal in terms of both production and consumption, after steel. Due to its lightweight nature and increasingly wide range of applications, aluminum production has been increasing year by year. Currently, the production process for aluminum ingots involves first melting molten aluminum, then pouring the molten aluminum into a mold, and finally removing the ingot after cooling and solidification. High-utility aluminum ingots are produced primarily from recycled aluminum. The ingot stacking mechanism uses a cylinder on one side to independently drive a clamping plate on the other. However, due to the difficulty in precisely controlling the coordination of the two cylinders' movements, the clamping plates on both sides may open and close asynchronously, causing the aluminum ingot to easily tilt or fall during clamping. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide an aluminum ingot stacking mechanism.

[0004] This utility model provides an aluminum ingot stacking mechanism, including a connector 1. A mounting plate 2 is horizontally arranged at the lower end of the connector 1. Hinged arms 5 are rotatably and symmetrically arranged on the left and right sides of the mounting plate 2. A cylinder 3 is arranged in the middle of the mounting plate 2 facing upward. A hinge rod 4 is connected between the piston rod of the cylinder 3 and the hinged arms 5 on its left and right sides. A clamping plate 6 for clamping aluminum ingots is installed on the hinged arms 5.

[0005] Furthermore, the two cylinders 3 are symmetrically arranged on the mounting plate 2, one in front of the other.

[0006] Furthermore, the mounting plate 2 has weight-reducing grooves around its perimeter and a weight-reducing hole in its center.

[0007] Furthermore, fixing strips 7 are symmetrically arranged on the front and rear sides of the bottom of the mounting plate 2, and a fixing shaft 8 is longitudinally arranged between the fixing strips 7 to allow the hinge arm 5 to rotate.

[0008] Furthermore, the hinge arm 5 is composed of a rotating part in the middle connecting an upper hinge part and a mounting part on the lower side. The mounting part has a countersunk hole, and the clamping plate 6 is installed on the mounting part by bolts passing through the countersunk hole.

[0009] Furthermore, the mounting plate 2 is equipped with guide posts 9 that can slide up and down around its perimeter. Each guide post 9 is fitted with an elastic element that connects the guide post 9 and the mounting plate 2. Pressure strips 11 are longitudinally arranged at the bottom of the two guide posts 9.

[0010] Furthermore, a guide sleeve 10 is installed on the mounting plate 2 to accommodate the guide post 9 sliding up and down, and a limiting block is installed at the top of the guide post 9 to abut against the guide sleeve 10.

[0011] The advantages of this invention are as follows: the cylinder simultaneously drives the clamping plates on both sides via the hinge rod and hinge arm, achieving synchronous opening and closing of the double clamping plates and avoiding uneven force on one side; the connecting parts enable the mechanism to be stably connected to the moving end of the robot arm; the symmetrical hinge arms are distributed left and right along the mounting plate, avoiding the problem of excessive lateral dimensions in the traditional parallel double cylinder structure and improving the flexibility of equipment layout; the hinge rod and hinge arm form a crank-connecting rod mechanism, and the linear motion of the cylinder is converted into the clamping force of the clamping plates through the lever principle; the rotating part acts as a fulcrum, ensuring that the hinge arm rotates around a fixed axis, and the hinge part is connected to the hinge rod. The drive force is transmitted, and the mounting part is far from the fulcrum. The clamping torque is increased by extending the lever arm. The clamping plates are fixed by bolts and can be disassembled and replaced individually after wear, without the need to disassemble the entire articulated arm. The weight of the mechanism is reduced by weight reduction grooves and weight reduction holes. The cylinder drives one end of the articulated rod to descend, and the other end of the articulated rod drives the articulated arm to rotate around the fixed axis, so that the two clamping plates on the articulated arm move towards the middle at the same time, thereby clamping the arranged aluminum ingots. The guide sleeve and guide post can ensure guiding stability and structural reliability, while reducing friction and wear. The limit block abuts against the top of the guide sleeve to limit the guide post from moving further downward. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0018] See Figures 1 to 4This utility model provides an aluminum ingot stacking mechanism, which includes a connector 1. The connector enables the mechanism to be stably connected to the movable end of a robotic arm. A mounting plate 2 is horizontally arranged at the lower end of the connector 1. Hinged arms 5 are rotatably and symmetrically arranged on the left and right sides of the mounting plate 2. A cylinder 3 is arranged in the middle of the mounting plate 2 facing upward. The symmetrical hinged arms are distributed along the left and right sides of the mounting plate, avoiding the problem of excessive lateral dimensions in the traditional parallel double cylinder structure and improving the flexibility of equipment layout. The piston rod of the cylinder 3 is connected to the hinged arms 5 on both sides by hinge rods 4. Clamping plates 6 for gripping aluminum ingots are installed on the hinged arms 5. The hinge rods and hinged arms form a crank-connecting rod mechanism. Linear motion is converted into clamping force of the clamping plates through the lever principle. The middle cylinder simultaneously links the left and right hinge arms through the hinge rod, and the symmetrical structure realizes the synchronous opening and closing of the double clamping plates, avoiding the tilting or falling of aluminum ingots due to uneven force on one side. The hinge arm 5 is composed of a middle rotating part connected to the upper hinge part and the lower mounting part. The mounting part has a countersunk hole. The clamping plate 6 is installed in the mounting part by bolts passing through the countersunk hole. The rotating part serves as a fulcrum to ensure that the hinge arm rotates around the fixed axis. The hinge part is connected to the hinge rod to transmit the driving force. The mounting part is away from the fulcrum and increases the clamping torque by extending the lever arm. The clamping plate is fixed by bolts and can be disassembled and replaced separately after wear without disassembling the entire hinge arm.

[0019] Two cylinders 3 are symmetrically arranged on the mounting plate 2. The cylinders correspond to the hinge arms on the left and right sides. The two hinge arms on the left side are fitted with the left clamping plate, and the two hinge arms on the right side are fitted with the right clamping plate.

[0020] The mounting plate 2 has weight-reducing grooves around its perimeter and a weight-reducing hole in its center. The weight of the mechanism is reduced by using the weight-reducing grooves and the weight-reducing hole.

[0021] See Figure 1 , Figure 2 The mounting plate 2 has symmetrical fixing strips 7 on the front and back sides of its bottom. A fixing shaft 8 for rotating the hinge arm 5 is longitudinally arranged between the fixing strips 7. The left and right ends of the fixing strips extend out of the mounting plate. The cylinder drives one end of the hinge rod to descend, and the other end of the hinge rod drives the hinge arm to rotate around the fixing shaft, so that the two clamping plates on the hinge arm move towards the middle at the same time, thereby clamping the arranged aluminum ingots.

[0022] The mounting plate 2 is equipped with guide pillars 9 that slide up and down around its perimeter. Each guide pillar 9 is fitted with an elastic element that connects it to the mounting plate 2. Pressure strips 11 are longitudinally arranged at the bottom of the two guide pillars 9. The pressure strips descend and contact the aluminum ingots arranged on the conveyor belt below. The elasticity of the elastic element causes the pressure strips to flatten the aluminum ingots so that the subsequent clamping plates can hold the arranged aluminum ingots.

[0023] The mounting plate 2 is equipped with a guide sleeve 10 that slides up and down the guide post 9. A limiting block is installed at the top of the guide post 9, which abuts against the guide sleeve 10. The guide sleeve and guide post can ensure guiding stability and structural reliability, while reducing friction and wear. The limiting block abuts against the top of the guide sleeve to restrict the guide post from moving further downward.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
