Description

Technical Field

[0001] This utility model relates to the field of automotive parts production equipment technology, and in particular to a surface strengthening treatment device for automotive parts. Background Technology

[0002] The surface strengthening treatment device for automotive parts is suitable for surface strengthening of various automotive parts, such as springs, shafts, gears, connecting rods, and wheels—critical components subjected to cyclic alternating loads. Furthermore, this device can also be widely applied to other mechanical parts requiring surface strengthening treatment.

[0003] Existing supersonic spraying equipment is used for surface wear-resistant strengthening treatment of automotive parts such as gear rings. Supersonic spraying utilizes supersonic airflow to accelerate wear-resistant materials to extremely high speeds, impacting the workpiece surface to form a coating. Supersonic spraying equipment can achieve high-speed, high-quality spraying and is suitable for spraying materials with high hardness and high wear resistance.

[0004] Existing supersonic spraying equipment cannot automatically adjust the position of the workpiece during the spraying process, requiring manual adjustment. Because the workpiece position cannot be automatically adjusted, the positional parameters between the spray gun and the workpiece are in a fixed state, which affects the uniformity of the coating. The coating thickness on the toothed ring is inconsistent, which not only affects the appearance but may also reduce the service life of the coating. At the same time, manual adjustment has the drawbacks of low production efficiency and additional labor costs. To address these issues, we propose a surface strengthening treatment device for automotive parts. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a surface strengthening treatment device for automotive parts, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a surface strengthening treatment device for automotive parts, comprising: a body, a support fixedly installed in the processing cavity of the body, a connecting shaft rotatably installed on the support, a connecting seat fixedly installed at one end of the connecting shaft, and a plurality of movable mechanisms arranged in a circumferential array on the outside of the connecting seat, the movable mechanisms being connected to the connecting seat.

[0007] The movable mechanism includes a top seat located outside the connecting seat, the outer surface of which is arc-shaped. Two spaced-apart spring telescopic rods are fixedly installed on the connecting seat, with their movable ends fixedly connected to the top seat. A circular plate is fixedly installed on the connecting shaft, through which multiple guide rods arranged in a circumferential array are passed. An inclined block is fixedly installed at the end of each guide rod, and the inclined block contacts the top seat. A spring is sleeved on each guide rod, with both ends of the spring fixedly connected to the inclined block and the circular plate, respectively. A ring magnet is sleeved on the outside of the connecting shaft, and the ring magnet is fixedly connected to the multiple guide rods. The mechanism also includes a drive mechanism installed on a support, which is connected to the connecting shaft and used to drive the connecting shaft to rotate.

[0008] As a further technical solution of this utility model, anti-slip pads are fixedly connected to the outer arc surface of the connecting seat.

[0009] As a further technical solution of this utility model, the driving mechanism includes a motor and a synchronous belt mechanism. The motor is fixedly mounted on the support, and the synchronous belt mechanism is mounted on the end of the connecting shaft and the output shaft end of the motor. The motor drives the connecting shaft to rotate through the synchronous belt mechanism.

[0010] As a further technical solution of this utility model, a magnetic mechanism is provided on the support, and the magnetic mechanism is located on one side of the annular magnet. The magnetic mechanism is used to apply magnetic force to the annular magnet.

[0011] As a further technical solution of this utility model, the magnetic mechanism includes a plurality of electromagnets arranged in a circumferential array, the electromagnets being fixedly mounted on a support, and the electromagnets being positioned toward the annular magnet.

[0012] As a further technical solution of this utility model, a protective cover is provided on the outside of the motor.

[0013] This utility model provides a surface strengthening treatment device for automotive parts, which has the following advantages compared with the prior art:

[0014] 1. This design discloses a surface strengthening treatment device for automotive parts. During the spraying process, a motor operates and drives a synchronous belt mechanism to rotate a connecting shaft. The slow rotation of the connecting shaft drives a gear ring to rotate slowly around the connecting shaft, thereby continuously adjusting the spraying surface of the gear ring. The device can uniformly spray different positions of the gear ring, reducing the workload of manual operation.

[0015] 2. This design discloses a surface strengthening treatment device for automotive parts. The spring on the spring-loaded telescopic rod is in a compressed state, which, within a certain range, allows for the fixing of gear rings of different diameters. By energizing the electromagnet, the electromagnet exerts a repulsive force on the ring magnet, causing the top seat to apply pressure to the gear ring. Therefore, the device can fix gear rings of more different diameters, improving its applicability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a surface strengthening treatment device for automotive parts: a surface strengthening treatment device for automotive parts includes: a body 1, a support 2 fixedly installed in the processing cavity of the body 1, a connecting shaft 3 rotatably installed on the support 2, a connecting seat 4 fixedly installed at one end of the connecting shaft 3, and a plurality of movable mechanisms arranged in a circular array on the outside of the connecting seat 4, the movable mechanisms being connected to the connecting seat 4. The movable mechanism includes a top seat 5 located outside the connecting seat 4, the outer surface of the top seat 5 being an arc surface. Two spaced spring telescopic rods 7 are fixedly installed on the connecting seat 4, the movable ends of the spring telescopic rods 7 being fixedly connected to the top seat 5. A circular plate 8 is fixedly installed on the connecting shaft 3, and multiple guide rods 9 arranged in a circular array pass through the circular plate 8. An inclined block 10 is fixedly installed at the end of each guide rod 9, and the inclined block 10 contacts the top seat 5 respectively. A spring 11 is sleeved on each guide rod 9, and the two ends of the spring 11 are fixedly connected to the inclined block 10 and the circular plate 8 respectively. A ring magnet 12 is sleeved on the outside of the connecting shaft 3, and the ring magnet 12 is fixedly connected to the multiple guide rods 9. It also includes a drive mechanism installed on the support 2, the drive mechanism being connected to the connecting shaft 3 and used to drive the connecting shaft 3 to rotate.

[0023] The drive mechanism includes a motor 13 and a synchronous belt mechanism 14. The motor 13 is fixedly mounted on the support 2, and the synchronous belt mechanism 14 is mounted on the end of the connecting shaft 3 and the output shaft end of the motor 13. The motor 13 drives the connecting shaft 3 to rotate through the synchronous belt mechanism 14.

[0024] A schematic diagram of the device's operation can be found here. Figure 1 As shown, by placing the gear ring 16 outside multiple top seats 5 and setting the nozzle 17 towards the gear ring 16, when the machine body 1 is working, the nozzle 17 sprays wear-resistant material onto the surface of the gear ring 16 to form a wear-resistant coating. The spring on the spring telescopic rod 7 is in a compressed state, and the spring telescopic rod 7 applies a pushing force to the top seats 5, causing the top seats 5 to press against the gear ring 16, thereby fixing the gear ring 16 outside the multiple top seats 5. At this time, the spring 11 is in a normal state. During the spraying process, the motor 13 works and drives the connecting shaft 3 to rotate through the synchronous belt mechanism 14. The connecting shaft 3 rotates slowly, which can drive the gear ring 16 to rotate slowly around the connecting shaft 3, thereby continuously adjusting the spraying surface of the gear ring 16. The device can uniformly spray different positions of the gear ring 16, reducing the workload of manual operation.

[0025] The spring on the spring telescopic rod 7 is in a compressed state, which is within a certain range, thus allowing for the fixing of gear rings 16 of different diameters. When the spring on the spring telescopic rod 7 is in a neutral state, the top seat 5 exerts no pressure on the gear ring 16.

[0026] Anti-slip pads 6 are fixedly connected to the outer arc surface of the connecting seat 4 to increase the friction between the connecting seat 4 and the gear ring, making it less likely for the connecting seat 4 to detach from the gear ring. A magnetic mechanism is provided on the support 2, located on one side of the annular magnet 12, and is used to apply magnetic force to the annular magnet 12. The magnetic mechanism includes multiple electromagnets 15 arranged in a circumferential array, which are fixedly mounted on the support 2 and face the annular magnet 12. A protective cover is provided around the motor 13 to protect it.

[0027] When fixing a gear ring 16 with a larger diameter, the top seat 5 cannot apply pressure to the gear ring 16 simply by using the spring telescopic rod 7. Therefore, by energizing the electromagnet 15, the electromagnet 15 applies a repulsive force to the annular magnet 12. The annular magnet 12, the guide rod 9, and the wedge block 10 move synchronously. The wedge block 10 pushes the top seat 5 to expand outward, thereby causing the top seat 5 to apply pressure to the gear ring 16. At this time, the spring on the spring telescopic rod 7 is in a stretched state. Therefore, the device can fix gear rings 16 with more different diameters, improving the applicability of the device.

[0028] The working principle of this utility model is as follows: (See the schematic diagram of the device for reference.) Figure 1 As shown, by placing the gear ring 16 outside multiple top seats 5 and setting the nozzle 17 towards the gear ring 16, when the machine body 1 is working, the nozzle 17 sprays wear-resistant material onto the surface of the gear ring 16 to form a wear-resistant coating. The spring telescopic rod 7 is in a compressed state, and the spring telescopic rod 7 applies a pushing force to the top seats 5, causing the top seats 5 to press against the gear ring 16, thereby fixing the gear ring 16 outside the multiple top seats 5. At this time, the spring 11 is in a normal state. During the spraying process, the motor 13 works and drives the connecting shaft 3 to rotate through the synchronous belt mechanism 14. The connecting shaft 3 rotates slowly, which can drive the gear ring 16 to rotate slowly around the connecting shaft 3, thereby continuously adjusting the spraying surface of the gear ring 16.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
