Abstract
Description
Technical Field
[0001] This utility model relates to the field of suspension technology for carburizing and quenching, and in particular to a suspension assembly for carburizing and quenching parts. Background Technology
[0002] In carburizing and quenching, a common heat treatment process for metallic materials, suspension components, as load-bearing parts, are key components for carburizing and quenching. Their performance directly affects the processing quality and production efficiency of the parts. Carburizing and quenching can give parts high surface hardness, improve wear resistance and strength, and is widely used in various mechanical parts such as gears, shafts, and piston pins. It is indispensable in the motorcycle manufacturing industry, where many key components require this process to ensure vehicle performance.
[0003] The patent publication number "CN216889715U" discloses "This utility model belongs to the technical field of large gear tooling lifting tools, and discloses a tooling lifting tool for gear carburizing and quenching. It includes a fixed bottom ring, a cross-shaped base frame fixedly connected inside the fixed bottom ring, a fixed plate fixedly connected to the top of the cross-shaped base frame, a connecting cylinder rotatably connected to the top of the fixed plate, and four support rods fixedly connected to the outside of the fixed plate, arranged in a cross shape. This utility model uses the fixed bottom ring as the main support of the device. In use, a large gear is placed horizontally on the four support rods, with the connecting cylinder and connecting frame passing through the central slot of the gear. Then, the four clamping components inside the slot are turned to position and clamp the gear, making it firmly connected to the support rods. This achieves the advantages of better gear positioning and fixing, and the part of the gear bottom in contact with the lifting tool is easy to move during quenching, increasing the uniformity of quenching."

Focusing on the suspension of large parts wastes furnace space, while processing small parts separately increases the number of processes. Furthermore, it does not solve the problem of suspension for motorcycle parts with large size differences, and its functions are homogenized with ordinary suspension equipment, failing to meet the requirements of efficient and high-quality carburizing and quenching operations.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0021] Please see Figures 1-5 A suspension assembly for carburizing and quenching parts includes a base frame 1 and a slide rod 20 fixedly connected to the inner side of the base frame 1. The slide rod 20 is fixedly connected to the front and rear sides inside the base frame 1. Two sliders 11 are slidably connected to the outer side of the slide rod 20. A bidirectional threaded rod 2 is rotatably connected to the inner side of the base frame 1. Two sliders 11 are screwed to the outer side of the bidirectional threaded rod 2. The two sliders 11 are respectively screwed to the outer side of different threads of the bidirectional threaded rod 2.
[0022] First, the base frame 1 serves as the basic framework for the carburizing and quenching suspension assembly of motorcycle parts, providing stable support for the entire device and adapting to the working space inside the carburizing and quenching furnace. The sliding rods 20 fixed on its front and rear sides provide sliding guidance for the sliders 11, ensuring smooth movement and preventing deviation. The bidirectional threaded rod 2, rotatably connected inside the base frame 1, is the core component for adjusting the spacing of the sliders 11. Since the two sliders 11 are respectively screwed onto the outer sides of the threads of the bidirectional threaded rod 2 with different directions of rotation, when the bidirectional threaded rod 2 rotates, it will drive the two sliders 11 to move towards or away from each other along the sliding rod 20. By adjusting the spacing of the sliders 11 to accommodate the different sizes of parts, the suspension requirements of large parts of varying specifications can be met, ensuring balanced force distribution after suspension and preventing positional deviations from affecting machining accuracy during the carburizing and quenching process.
[0023] Furthermore, a turntable 3 is rotatably connected to the outer side of the base frame 1. The output shaft of the turntable 3 passes through the base frame 1 and is fixedly connected to the bidirectional threaded rod 2. The bottom sides of the sliders 11 on both sides are fixedly connected to the main hanging plates 12, and the outer side of the main hanging plates 12 is provided with main hanging holes 14. The turntable 3 on the outer side of the base frame 1 provides a convenient adjustment interface for the operator. Without the need for complicated tools, the output shaft passing through the base frame 1 can be rotated manually by rotating the turntable 3, thereby driving the bidirectional threaded rod 2 to rotate synchronously. This reduces the difficulty of adjusting the distance between the sliders 11 and meets the need for frequent adjustment of the suspension position of the parts during carburizing and quenching operations. The main hanging plates 12 fixed to the bottom sides of the left and right sliders 11 are designed specifically for suspending large parts. The main hanging holes 14 on the outer side of the main hanging plates 12 can be connected to the reserved mounting holes or force points of the large parts through hook connectors to achieve stable suspension of the large parts. Moreover, the distance between the main hanging plates 12 and the sliders 11 can be adjusted synchronously, and the suspension point position can be flexibly adjusted according to the size of the large parts to ensure that the large parts remain horizontal and are heated evenly during carburizing and quenching, and to avoid deformation of the parts due to unstable suspension.
[0024] Furthermore, a fixing bolt 13 is screwed into the inner side of the main hanging hole 14, and a nut 15 is screwed into the outer side of the fixing bolt 13. A T-shaped fixing plate 16 is provided on the outer side of the main hanging hole 14. The T-shaped fixing plate 16 is screwed through and fixed to the outer side of the main hanging plate 12 by the fixing bolt 13. A sliding plate 17 is provided below the T-shaped fixing plate 16. A sliding groove 22 is opened on the top of the sliding plate 17. The T-shaped fixing plate 16 slides on the inner side of the nut 15. A secondary hanging plate 19 is fixedly connected to the bottom of the sliding plate 17. A secondary hanging hole 18 is opened on the side of the secondary hanging plate 19. The fixing bolt 13 on the inner side of the main hanging hole 14 cooperates with the nut 15 on the outer side to firmly fix the T-shaped fixing plate 16 to the outer side of the main hanging plate 12. Tightening the nut 15 can enhance the fixing stability of the T-shaped fixing plate 16 and prevent it from loosening due to vibration during the carburizing and quenching process. The slide plate 17 below the T-shaped fixed plate 16 slides with the T-shaped fixed plate 16 through the top slide groove 22. The operator can adjust the position of the slide plate 17 along the slide groove 22, thereby changing the suspension height and horizontal position of the bottom secondary hanging plate 19. The secondary hanging plate 19 is designed for suspending small parts. Its side secondary hanging holes 18 can be connected to small parts through thin hooks or steel wires to realize the batch suspension of small parts. At the same time, the sliding adjustment structure can prevent small parts from colliding or blocking each other, ensuring that each small part can fully contact the carburizing and quenching medium and guarantee the processing quality. In addition, the layered design of the main hanging plate 12 for hanging large parts and the secondary hanging plate 19 for hanging small parts can make full use of the furnace space and increase the processing capacity of parts in a single carburizing and quenching process.
[0025] Furthermore, long support plates 4 are fixedly connected to the top left and right ends of the bottom frame 1, and short support plates 5 are fixedly connected to the front and rear ends of the bottom frame 1. A connecting plate 10 is fixedly connected to the top of the long support plates 4 and the short support plates 5. The long support plates 4 at the top left and right ends of the bottom frame 1 and the short support plates 5 at the front and rear ends together constitute the top support structure of the suspension assembly. The long support plates 4 are adapted to the length direction of the bottom frame 1, and the short support plates 5 are adapted to the width direction. The two are connected as a whole by the connecting plate 10 at the top, which enhances the structural strength and stability of the entire suspension assembly. During the carburizing and quenching process of motorcycle parts, the assembly needs to bear the weight of multiple large and small parts. The long support plates 4 and the short support plates 5 can distribute the weight pressure and prevent the bottom frame 1 from deforming due to concentrated stress. At the same time, the connecting plate 10 provides an installation foundation for subsequent connection with the hoisting equipment, ensuring that the entire assembly can be smoothly hoisted into or out of the carburizing and quenching furnace, ensuring operational safety.
[0026] Furthermore, a connecting cylinder 9 is fixedly connected to the inner side of the connecting plate 10, and multiple connecting posts 21 are fixedly connected to the bottom inner side of the connecting cylinder 9. A connecting plate 8 is fixedly connected to the top of the connecting posts 21. The connecting cylinder 9 on the inner side of the connecting plate 10 provides a fixed installation space for the connecting posts 21. The structural design of the connecting cylinder 9 can enhance the stability of the connecting posts 21 and prevent the connecting posts 21 from bending and deforming under stress. The multiple connecting posts 21 on the bottom inner side of the connecting cylinder 9 are evenly distributed and jointly support the connecting plate 8 on top, ensuring that the connecting plate 8 is subjected to balanced force. As the core connecting component between the suspension assembly and the external hoisting equipment, the flat top surface of the connecting plate 8 can stably cooperate with the hooks or connectors of the hoisting equipment. The design of multiple connecting posts 21 can distribute the overall weight borne by the connecting plate 8, prevent excessive force at a single point from causing damage to the component, and ensure the safety and stability of the assembly when hoisting motorcycle parts into / out of the carburizing and quenching furnace.
[0027] Furthermore, a lifting ring 6 is provided at the top of the connecting plate 8, and a hydraulic rod 7 is fixedly connected to the bottom of the lifting ring 6. The output shaft of the hydraulic rod 7 is fixedly installed to the top of the connecting plate 8. The lifting ring 6 at the top of the connecting plate 8 is a component that is directly connected to external lifting equipment. Its ring structure facilitates the quick attachment and removal of the hooks of the lifting equipment, adapting to the needs of frequent lifting in carburizing and quenching operations. The hydraulic rod 7 at the bottom of the lifting ring 6 has a telescopic adjustment function. By controlling the extension and retraction of the output shaft of the hydraulic rod 7, the height of the entire suspension assembly can be adjusted: when lifting into the carburizing and quenching furnace, shortening the hydraulic rod 7 lowers the assembly to a suitable position inside the furnace, ensuring that the parts are fully immersed in the carburizing and quenching medium or in the optimal heating zone; when lifting out, extending the hydraulic rod 7 raises the assembly, making it convenient for operators to pick up and put down the parts; at the same time, the buffering characteristics of the hydraulic rod 7 can reduce the impact force generated by the start and stop of the equipment during the lifting process, avoiding damage to motorcycle parts due to vibration, and ensuring the accuracy and quality of the parts after processing.
[0028] Overall Workflow: When the suspension assembly for carburizing and quenching motorcycle parts is in operation, the base frame 1 provides stable support as a basic frame. The sliding rods 20 on both the front and rear sides inside guide the sliding blocks 11 to slide. The operator rotates the outer turntable 3 of the base frame 1, causing the inner bidirectional threaded rod 2 to rotate, making the two sliding blocks 11, screwed onto threads of different directions, move towards or away from each other, adjusting the spacing to accommodate large parts of different specifications. The main hanging plate 12 on the bottom side of the sliding block 11 suspends the large parts through the main hanging hole 14 and connecting parts. The main hanging plate 12 adjusts with the sliding block 11 to ensure balanced horizontal force on the large parts. The fixing bolts 13 and nuts 15 at the main hanging hole 14 fix the T-shaped fixing plate 16 to the outside of the main hanging plate 12. The T-shaped fixing plate 16 slides along the top groove 22 of the slide plate 17, adjusting the position of the secondary hanging plate 19 at the bottom of the slide plate 17. The secondary hanging plate 19 suspends small parts through the secondary hanging hole 18, preventing collisions and obstructions. The layered design improves the utilization of space inside the furnace. The top long support plate 4 and short support plate 5 of the bottom frame 1 support the connecting plate 10, enhancing the structural strength of the component. Multiple connecting columns 21 fixed to the connecting cylinder 9 inside the connecting plate 10 evenly support the connecting plate 8, ensuring balanced force. The top lifting ring 6 of the connecting plate 8 is connected to the external lifting equipment. The hydraulic rod 7 at the bottom of the lifting ring 6 adjusts the height of the component by telescopic adjustment. When hoisting into the furnace, it shortens to place the parts in the optimal processing area, and when hoisting out, it extends for easy handling. At the same time, it buffers the impact of hoisting, ensuring the processing accuracy and quality of the parts. Overall, it achieves stable suspension and convenient operation for carburizing and quenching of large and small motorcycle parts.
