[0040] The embodiments of the utility model are described in detail below, and the examples of the embodiments are represented in the drawings, wherein the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0042] In the technical field of clamps, in view of many problems existing in clamping agricultural machine counterweight plate by traditional clamps, the clamping device for agricultural machine counterweight part machining of the utility model is designed, through cooperative work of each part, efficient and stable clamping function is realized, as follows:

[0043] For example Figures 1-7As shown, the clamping device is mainly matched with the counterweight placing rack, and is used for clamping the counterweight plates 4 stacked on the placing rack. The core component of the clamping device is two oppositely arranged clamping arms 5, which are respectively located on the two sides of the counterweight placing rack. On the opposite surface of the clamping arm 5 and the counterweight placing rack, a first clamping groove 6 and a second clamping groove 7 are designed to be matched with the counterweight plates 4. The second clamping groove 7 is located at the opening of the first clamping groove 6, and the slope of the lower end surface of the second clamping groove 7 forms a shovel plate 8. This unique design is the key to efficient clamping.

[0044] As shown in Figure 4 , the number of the first clamping grooves 6 on the clamping arm 5 is multiple, and they are uniformly distributed along the length direction of the clamping arm 5. The openings of the multiple first clamping grooves 6 are connected through a second clamping groove 7. This design enables the extension of multiple counterweight plates to be clamped at the same time, realizes stable clamping of multiple counterweight plates, and improves the work efficiency. At the same time, the first clamping groove 6 is closely matched with the extension of the counterweight plate 4, which prevents the counterweight plate from moving in the horizontal direction. The second clamping groove 7 is matched with the end of the counterweight plate 4, which further fixes the counterweight plate and ensures the stability of the counterweight plate during clamping and transferring.

[0045] As shown in Figure 3 and Figure 6 , the slope of the shovel plate 8 extends to the inner cavity lower end surface of the first clamping groove 6 at the upper end, and extends to the lower end surface edge of the second clamping groove 7 at the lower end. During clamping, the shovel plate 8 is inserted into the gap between the counterweight plate 4 and the counterweight placing rack by using the slope. With the gradual inward movement of the clamping arm 5, the shovel plate 8 gradually lifts the counterweight plate upward, so that the counterweight plate is separated from the placing rack, which facilitates clamping multiple counterweight plates at one time, and solves the problems of difficulty in inserting the traditional clamp into the gap and clamping multiple counterweight plates at the same time.

[0046] As shown in Figure 7 , the counterweight placing rack is composed of a base 1, a fixed rod 2 and a cushion block 3. The base 1 provides a stable support foundation for the entire placing rack. Multiple fixed rods 2 are uniformly distributed along the length direction of the counterweight plate 4. The counterweight plate 4 is sleeved on the fixed rod 2 through the assembly hole. This design facilitates the stacking and positioning of the counterweight plate, and makes the counterweight plate more stable on the placing rack, which is not easy to shake or deviate. The number of cushion blocks 3 is at least two and they are symmetrically distributed on the two sides of the base 1, which are used to support the extensions at both ends of the counterweight plate 4, avoiding direct contact between the counterweight plate and the base, reducing wear and tear, and also providing space for the shovel plate 8 to insert into the gap between the counterweight plate and the placing rack.

[0047] As shown in Figure 3 , Figure 4 and Figure 6As shown, the lower end surface of the clamping arm 5 is provided with a guide groove 9 matched with the cushion block 3, and the side of the guide groove 9 close to the counterweight plate 4 is open. During clamping, the lower end surface of the clamping arm 5 slides on the upper end surface of the base 1, and the guide groove 9 is slidingly assembled with the cushion block 3. This design plays a guiding role, ensures that the clamping arm 5 can accurately move to the position of the counterweight plate, and improves the clamping accuracy. At the same time, the open design of the guide groove 9 facilitates the smooth insertion of the shovel plate 8 into the gap between the counterweight plate and the placing rack, and cooperates with the action of the shovel plate 8 to lift the counterweight plate upward, making the entire clamping process more stable and reliable.

[0048] As Figure 2 shown, the device is also equipped with a driving mechanism 11 installed on the movable end of the external lifting device. The bottom of the driving mechanism 11 has two movable ends, and the upper end of the clamping arm 5 is connected to the movable end of the driving mechanism 11 through a boom 10. The driving mechanism 11 can be an electric sliding rail, a motor lead screw combination structure, etc., which can accurately control the two clamping arms 5 to move closer or farther away from each other, realize the clamping and loosening operation of the counterweight plate, and at the same time, cooperate with the external lifting device to drive the clamping arm 5 to ascend or descend, complete the transfer work of the counterweight plate, realize the automatic control of the clamping process, and improve the convenience of operation and the stability of clamping.

[0049] In order to further optimize the movement performance of the clamping arm 5, a ball is installed at the lower end surface of the clamping arm 5. When the driving mechanism 11 drives the clamping arm 5 to act, the lower end surface of the clamping arm 5 is rollingly connected to the upper end surface of the base 1 through the ball. In this way, the sliding friction between the clamping arm and the base is converted into rolling friction, greatly reducing the resistance when the clamping arm 5 moves, making the movement of the clamping arm 5 more smooth, reducing energy consumption, and at the same time, the existence of the ball reduces the wear between the clamping arm 5 and the base 1, prolongs the service life of the equipment, and improves the stability of the clamping arm 5 during movement, avoids the shaking of the clamping arm caused by uneven friction, and ensures the stability and reliability of the clamping process.

[0050] In the actual agricultural machinery counterweight processing scene, the counterweight plate 4 is sleeved on the fixed rod 2 through the assembly hole and is placed on the counterweight placing rack, the cushion block 3 supports the counterweight plate 4, when the counterweight plate needs to be clamped and transferred, the driving mechanism 11 controls the two clamping arms 5 to approach each other, the guide groove 9 on the lower end surface of the clamping arm 5 slides along the cushion block 3, and accurate movement to the counterweight plate position is ensured, at this time, the shovel plate 8 is inserted into the gap between the counterweight plate 4 and the placing rack, with the gradual advancement of the clamping arm 5, the shovel plate 8 gradually lifts the counterweight plate upward, the plurality of first clamping grooves 6 and the second clamping grooves 7 respectively clamp the extension part and the end part of the counterweight plate, stable clamping of the plurality of counterweight plates is realized, then, the driving mechanism 11 cooperates with the external lifting equipment to transfer the clamped counterweight plate into the annealing furnace and other processing equipment, in the whole process, the ball on the lower end surface of the clamping arm 5 ensures the smoothness and stability of movement, the problems existing in the traditional clamp are effectively solved, and the clamping efficiency and processing quality are improved.

[0051] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
