Description

Technical Field

[0001] The utility model belongs to the technical field of angle change, and particularly relates to a servo angle change mechanism. Background Art

[0002] In the manufacturing process of plastic products, welding is a crucial link. Especially for plastic products that need to be welded at multiple angles, there are many deficiencies in the existing welding processes and auxiliary mechanisms. Traditional welding methods often require multiple fixed auxiliary welding mechanisms to achieve multi-angle welding of products, which not only increases the complexity and cost of equipment, but also has fixed welding angles, lacking flexibility and adjustability.

[0003] Specifically, traditional welding auxiliary mechanisms usually can only provide a limited number of fixed welding angles and cannot meet the welding requirements of products at different angles. When the welding angle needs to be changed, it is often necessary to replace the entire auxiliary mechanism or readjust the equipment, which is not only time-consuming and laborious, but also greatly reduces production efficiency. In addition, due to the fixity of the welding angle, it also limits the diversity and flexibility of product design.

[0004] Therefore, it is very necessary to invent a servo angle change mechanism. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a servo angle change mechanism, which includes a base, a mounting seat, an adjusting plate, a connecting block and a ninety-degree adjusting mechanism. The mounting seats are fixedly installed at two of the corners above the base. There are two mounting seats in total. An adjusting plate is rotatably installed between the two mounting seats. A connecting block is fixedly installed on the inner surface of the adjusting plate. The connecting block is connected to the ninety-degree adjusting mechanism installed on the base.

[0006] Preferably, the ninety-degree adjusting mechanism includes a fixed seat, a ball screw, a servo motor, a sliding press block and a connecting rod arm. The two fixed seats are installed on the base. A ball screw is rotatably installed on the two fixed seats. Any end of the ball screw is fixed to the output end of the servo motor fixedly installed on the base. The ball screw is connected to the sliding press block through a ball nut. The sliding press block is connected to the connecting block through the two connecting rod arms.

[0007] Preferably, shock absorbers are provided on both sides of the fixed seat away from the servo motor. There are two shock absorbers in total. A limiting block is provided on the outer side of each shock absorber. The limiting blocks are installed at the other two corners of the base. The limiting blocks are used to limit the adjusting plate.

[0008] Preferably, a bottom frame is fixedly installed on the periphery above the base. An activity frame with the same structure as the bottom frame is installed on the periphery of the lower surface of the adjusting plate. The activity frame has a "U" shape structure.

[0009] Preferably, a telescopic cover is installed between the bottom frame and the movable frame, and the telescopic cover is located outside the ninety-degree adjustment mechanism and the limit block.

[0010] Preferably, the cross section of the telescopic cover is wavy, the telescopic cover allows telescopic movement, and the telescopic cover is made of rubber material.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model realizes flexible adjustment of the angle of the adjustment plate and the plastic product mounted thereon by driving the ball screw to rotate via a servo motor. This adjustment method is not only highly accurate, but also has a wide adjustment range, which can meet the welding needs of different angles. At the same time, the entire mechanism is compact and occupies little space.

[0020] As attached Figure 1 To the attached Figure 3 As shown:

[0021] The servo angle changing mechanism provided by the present invention includes a base 1, a mounting seat 2, an adjustment plate 3, a connecting block 4 and a ninety-degree adjustment mechanism 5. The mounting seat 2 is fixedly installed at two corners above the base 1. There are two mounting seats 2 in total. The adjustment plate 3 is rotatably installed between the two mounting seats 2. The inner surface of the adjustment plate 3 is fixedly installed with a connecting block 4, and the connecting block 4 is connected to the ninety-degree adjustment mechanism 5 installed on the base 1.

[0022] Furthermore, the 90-degree adjustment mechanism 5 includes a fixed seat 51, a ball screw 52, a servo motor 53, a sliding press block 54, and a connecting rod arm 55. The two fixed seats 51 are firmly installed on the base 1, providing stable support for the ball screw 52. The ball screw 52 is rotatably installed between the two fixed seats 51, and one end thereof is closely connected to the output end of the servo motor 53 fixedly installed on the base 1. When the servo motor 53 is started, it drives the ball screw 52 to rotate. The ball screw 52 is connected to the sliding press block 54 through a ball nut, so the rotation of the ball screw 52 drives the sliding press block 54 to perform linear movement. The sliding press block 54 is connected to the connecting block 4 through two connecting rod arms 55, thereby realizing the angle adjustment of the adjusting plate 3 and the plastic products installed thereon.

[0023] Furthermore, in order to further improve the stability and safety of the mechanism, shock absorbers 56 are provided on both sides of the fixed seat 51 far from the servo motor 53. There are two shock absorbers 56 in total, which can effectively absorb the force after the adjusting plate 3 is reset, ensuring the reset stability of the adjusting plate 3. A limit block 6 is provided on the outside of each shock absorber 56, and the limit block 6 is installed at the other two corners of the base 1. The main function of the limit block 6 is to limit the rotation range of the adjusting plate 3, prevent it from rotating excessively or deviating from the preset position, so as to ensure the smooth progress of the welding process.

[0024] Furthermore, a bottom frame 7 is fixedly installed on the outer periphery above the base 1, which provides a stable support frame for the entire mechanism. An active frame 8 with the same structure as the bottom frame 7 is installed on the outer periphery of the lower surface of the adjusting plate 3. The active frame 8 adopts a "U" - shaped structure and cooperates with the bottom frame 7, enabling the adjusting plate 3 to maintain stability during rotation. The design of the bottom frame 7 and the active frame 8 not only improves the overall stability of the mechanism but also facilitates the installation of the subsequent telescopic cover 9.

[0025] Furthermore, a telescopic cover 9 is installed between the bottom frame 7 and the active frame 8, which is located outside the 90 - degree adjustment mechanism 5 and the limit block 6. The cross - section of the telescopic cover 9 is wavy, and this design endows the telescopic cover 9 with good flexibility and durability. The telescopic cover 9 allows for telescopic movement and can freely expand and contract with the rotation of the adjusting plate 3, thus ensuring the dust - proof and splash - proof effects during the welding process. At the same time, the telescopic cover 9 is made of rubber material, having good elasticity and sealing performance, which can further improve the safety of the operator. The bottom frame 7, the active frame 8, and the telescopic cover 9 form a dust - proof structure.

[0026] The working principle is as follows: First, when the servo motor 53 is started, it drives the ball screw 52 to rotate between the two fixed seats 51. These two fixed seats 51 are firmly installed on the base 1, providing stable support for the ball screw 52. The rotation of the ball screw 52 drives the sliding press block 54 to perform linear movement through the ball nut.

[0027] Then, the movement of the sliding block 54 is transmitted to the connecting block 4 through the two connecting rod arms 55, thereby achieving angle adjustment of the adjustment plate 3 and the plastic product mounted thereon. This adjustment method is not only highly accurate but also has a wide adjustment range, which can meet the requirements of welding at different angles.

[0028] Furthermore, during the subsequent rotation and reset of the adjustment plate 3, the shock absorbers 56 on both sides of the fixing base 51, away from the servo motor 53, effectively absorb the force generated by the reset of the adjustment plate 3, ensuring the reset stability of the adjustment plate 3. Furthermore, the stoppers 6 provided on the outer sides of each shock absorber 56 limit the rotation range of the adjustment plate 3, preventing it from over-resetting or deviating from the preset position.

[0029] Furthermore, the bottom frame 7 above the base 1 provides a stable support framework for the entire mechanism, while the movable frame 8 below the adjustment plate 3 cooperates with the bottom frame 7 to ensure that the adjustment plate 3 remains stable during rotation. The design of the bottom frame 7 and movable frame 8 not only improves the overall stability of the mechanism but also facilitates the subsequent installation of the telescopic cover 9.

[0030] The telescopic cover 9 can freely expand and contract with the rotation of the adjustment plate 3. Its wave-shaped cross-section provides excellent elasticity and durability. Furthermore, the telescopic cover 9 is made of rubber, which has excellent elasticity and sealing properties, ensuring dust and splash protection during welding and further improving operator safety.

[0031] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
