Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, and in particular to a high-efficiency shot peening device for springs. Background Technology

[0002] In the field of spring manufacturing, shot peening is a widely used and crucial process for improving the fatigue strength and extending the service life of springs. In practical applications, an efficient spring shot peening device typically requires the following technologies:

[0003] 1. Shot peening mechanism: It adopts a high-performance shot peening device, which can accurately control the shot injection speed, flow rate and angle;

[0004] 2. Positioning and Rotation Mechanism: A specially designed clamp is used to precisely position the spring, ensuring that the spring is fixed in position during the shot peening process and avoiding uneven shot peening due to positional deviation. At the same time, a rotation device is provided to allow the spring to rotate around its own axis or a specific axis, ensuring that all parts of the spring are evenly impacted by the shot, achieving all-round shot peening strengthening.

[0005] 3. Shot recovery and screening mechanism: A shot recovery system is set up to collect the shot scattered during the shot peening process in a timely manner, thereby improving the utilization rate of shot and reducing production costs.

[0006] In the shot peening process of springs, the unique helical structure of springs brings significant challenges. Due to their helical shape, it is difficult for the inner wall of the spring to be fully and evenly impacted by the shot. In order to achieve effective strengthening of the spring, the relative position between the spring and the shot peening machine nozzle must be frequently adjusted. This process is not only cumbersome and time-consuming, but also seriously reduces the overall work efficiency. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a high-efficiency shot peening strengthening device for springs. It solves the significant challenges posed by the unique helical structure of springs in the shot peening strengthening process. Due to its helical shape, it is difficult for the inner wall of the spring to be fully and evenly impacted by the shot. In order to achieve effective strengthening of the spring, the relative position between the spring and the shot peening machine nozzle must be frequently adjusted. This process is not only cumbersome and time-consuming, but also seriously reduces the overall work efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A high-efficiency shot peening device for springs includes a support base, a rotating arm symmetrically and rotatably mounted on the support base, an end face helical gear symmetrically and fixedly mounted on the support base, a clamping rod rotatably mounted on the rotating arm, a pinion fixedly mounted at the end of the clamping rod, the pinion meshing with the end face helical gear, and a rubber sleeve fixedly mounted on the outer side of the clamping rod.

[0010] Preferably, the axes of the two clamping rods coincide, and the axes of the two rotating arms coincide.

[0011] Preferably, the axis of the clamping rod and the axis of the rotating arm are at a 30-degree angle.

[0012] Preferably, a dual-axis motor is fixedly installed on the side end of the support base.

[0013] Preferably, a synchronous pulley set is installed between the dual-shaft motor and the rotating arm.

[0014] Preferably, a protective plate is fixedly installed on the rotating arm.

[0015] Preferably, a shot peening machine nozzle is fixedly installed at the top of the support base.

[0016] Preferably, a shot blasting machine recovery hopper is fixedly installed at the bottom of the support base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Through the symmetrically arranged rotating arm and clamping rod linkage design, and utilizing the 30-degree angle between the clamping rod axis and the rotating arm axis, the spring, after being clamped on the rubber sleeve, is tilted and exposed below the shot peening nozzle. When the dual-axis motor drives the rotating arm to revolve through the synchronous pulley set, the helical gear fixed to the end face of the support base and the small gear at the end of the clamping rod are forcibly engaged, forcing the spring to synchronously rotate around its own axis.

[0025] This application provides a high-efficiency shot peening strengthening device for springs, effectively solving the significant challenges posed by the unique helical structure of springs in the shot peening process. Due to its helical shape, the inner wall of the spring is difficult to be fully and evenly impacted by the shot. To achieve effective strengthening of the spring, the relative position between the spring and the shot peening machine nozzle must be frequently adjusted. This process is not only cumbersome and time-consuming, but also seriously reduces the overall work efficiency. The device addresses this technical problem by using a symmetrically arranged rotating arm and clamping rod linkage design, utilizing a 30-degree clamping angle between the clamping rod axis and the rotating arm axis. The angle allows the spring, after being clamped on the rubber sleeve, to tilt and expose itself below the shot peening nozzle. When the dual-shaft motor drives the rotating arm to revolve via the synchronous pulley set, the helical gear fixed to the end face of the support base and the small gear at the end of the clamping rod are forcibly engaged, forcing the spring to synchronously rotate around its own axis. The tilted posture allows the inner wall of the spring to be directly exposed to the shot flow from the shot peening nozzle, ensuring that both the inner and outer sides of the spring are impacted by the shot. At the same time, the spring rotates, ensuring that the force is evenly distributed in each area. One clamping can simultaneously complete the inner wall strengthening and overall uniform shot peening, avoiding repeated adjustments and achieving the effect of improving work efficiency.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the significant challenge posed by the unique helical structure of the spring in the spring shot peening strengthening process. Due to its helical shape, the inner wall of the spring is difficult to be fully and evenly impacted by the shot. To achieve effective strengthening of the spring, the relative position between the spring and the shot peening machine nozzle must be frequently adjusted. This process is not only cumbersome and time-consuming, but also seriously reduces the overall work efficiency. The overall approach is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a spring-loaded high-efficiency shot peening strengthening device, including a support base 1, a rotating arm 2 symmetrically and rotatably mounted on the support base 1, an end face helical gear 3 symmetrically and fixedly mounted on the support base 1, a clamping rod 4 rotatably mounted on the rotating arm 2, and a small gear 5 fixedly mounted at the end of the clamping rod 4.

[0029] The pinion 5 meshes with the helical gear 3 on the end face. A rubber sleeve 6 is fixedly installed on the outside of the clamping rod 4. The axes of the two clamping rods 4 coincide, and the axes of the two rotating arms 2 coincide. There is a 30-degree angle between the axes of the clamping rods 4 and the axes of the rotating arms 2.

[0030] A dual-axis motor 7 is fixedly installed on the side end of the support base 1. A synchronous pulley set 8 is installed between the dual-axis motor 7 and the rotating arm 2. A protective plate 9 is fixedly installed on the rotating arm 2. A shot blasting machine nozzle 10 is fixedly installed on the top end of the support base 1. A shot blasting machine recovery hopper 11 is fixedly installed on the bottom end of the support base 1.

[0031] Support base 1: As the basic support structure of the entire device, it provides installation positions for other components. The top of the base is equipped with the shot blasting machine nozzle 10, the bottom is equipped with the shot blasting machine recovery hopper 11, and the side is equipped with the dual-shaft motor 7. The rotating arm 2 is symmetrically rotated and mounted on it, and the end face helical gear 3 is symmetrically fixed and mounted to ensure the relative positional relationship between the components and to make the entire device operate stably.

[0032] Rotating arm 2: It is connected to the output shaft of the dual-axis motor 7 through the synchronous pulley group 8. Under the drive of the dual-axis motor 7, it rotates around the support base 1, which drives the clamping rod 4 and the spring clamped on it to make circular motion, so that the spring continuously changes position during the shot peening process, so that different parts of the spring can be within the shot peening range of the shot peening nozzle 10 of the shot peening machine, thereby achieving multi-angle shot peening strengthening.

[0033] End face helical gear 3: When the rotating arm 2 drives the clamping rod 4 to rotate, it meshes with the pinion 5 to make the clamping rod 4 and the spring rotate around its own axis, ensuring that the spring is subjected to uniform force in each area during shot peening, and avoiding the problem of uneven shot peening caused by the angle between the spring and the rotating arm 2.

[0034] Clamping rod 4: Used to clamp the spring. Through the rotational connection with the rotating arm 2 and the meshing relationship with the end face helical gear 3, the spring can rotate on its own axis while revolving around the axis of the rotating arm 2. At the same time, there is a 30-degree angle between the clamping rod 4 and the axis of the rotating arm 2, so that the spring is in an inclined state after clamping, and the inner wall can be exposed within the shot peening range of the shot peening nozzle 10, which facilitates shot peening strengthening of the inner wall of the spring.

[0035] Pinion 5: When the rotating arm 2 drives the clamping rod 4 to rotate, the pinion 5 interacts with the end face helical gear 3, which transmits the rotation of the rotating arm 2 to the clamping rod 4, thereby causing the clamping rod 4 and the spring to rotate around their own axis, ensuring the uniformity of spring shot peening.

[0036] Rubber sleeve 6: Used to clamp the spring and protect the clamping rod 4. The two ends of the spring are fitted onto the rubber sleeve 6, and the spring is pressed against the rubber sleeve 6 by its own elastic force, thus achieving a fixed connection between the spring and the clamping rod 4. The rubber sleeve 6 has a certain degree of elasticity, which can not only ensure the stable clamping of the spring, but also prevent the clamping rod 4 from being damaged by the impact of projectiles.

[0037] Dual-shaft motor 7: As a power source, it provides power for the rotation of the rotating arm 2. Its output shafts at both ends are connected to the two rotating arms 2 through the synchronous pulley group 8, so that the two rotating arms 2 can rotate synchronously and ensure the stability of the spring during the shot peening process.

[0038] Synchronous belt pulley group 8: plays the role of transmitting power, transmitting the rotation of the output shaft of the dual-shaft motor 7 to the rotating arm 2, ensuring that the dual-shaft motor 7 can effectively drive the rotating arm 2 to rotate;

[0039] Protective plate 9: It plays a protective role during the spring shot peening process, preventing the impact of the shot splash on the gear structure and avoiding damage and jamming of the gear;

[0040] Shot peening machine nozzle 10: After the shot peening machine is started, shot is sprayed onto the spring through this nozzle to strengthen the spring. Its position design allows the spring to be shot peened from all directions and multiple angles during the spring's rotation around the axis of the rotating arm 2 and its own rotation, ensuring that all parts of the spring are impacted by the shot.

[0041] Shot peening machine recovery hopper 11: Used to collect the shot that falls off during the shot peening process. After shot peening is completed, the shot falls into the recovery hopper, which facilitates the recycling and reuse of the shot, improves the utilization rate of the shot, and reduces production costs.

[0042] Working principle:

[0043] The first step, during use, involves compressing the spring inward to induce a certain deformation. Then, the spring is fitted onto one end of the rubber sleeve 6, and the other end is aligned with the other rubber sleeve 6. Releasing the compression allows the spring to extend under its own elastic force. At this point, both ends of the spring are fitted onto the two rubber sleeves 6 respectively, and their elastic force presses them together. The spring's axis coincides with the axis of the clamping rod 4. After the shot peening machine starts, the spring is shot-peened through the shot peening nozzle 10. During this process, the dual-shaft motor 7 starts, and the output shafts at both ends of the dual-shaft motor 7 drive the rotating arm 2 synchronously via two sets of synchronous pulleys 8, causing the spring to rotate around the axis of the rotating arm 2. As the spring rotates, the inner wall of the spring is exposed to the shot peening range of the shot peening nozzle 10 because there is a 30-degree angle between the axis of the spring and the axis of the rotating arm 2. At the same time, because the pinion 5 and the end face helical gear 3 mesh, the spring will rotate around its own axis. Because there is an angle between the spring axis and the rotating arm 2, if the spring does not rotate, the area of ​​the spring near the axis of the rotating arm 2 will move away from the shot peening nozzle 10 when the rotating arm 2 rotates. Therefore, the shot peening force on this area will be lower than that on the area away from the axis of the rotating arm 2, which will lead to uneven shot peening force. However, the rotation of the spring allows different areas of the spring to face the shot peening nozzle 10, so that the force on each area is uniform.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
