Description

Technical Field

[0001] This utility model relates to the field of thrust ring laser cladding technology, and more specifically, to a coaxial powder feeding device for thrust ring laser cladding. Background Technology

[0002] Thrust rings are core components in mechanical systems that bear axial forces. They are commonly found in bearings, gearboxes, engines, and other equipment. The function of thrust rings is to limit the axial movement of rotating parts and ensure precise positioning of equipment. Due to long-term exposure to axial pressure, friction, and impact, the working surface of thrust rings is prone to failure problems such as wear, scratches, and corrosion. Traditional repair methods (such as welding and electroplating) have large heat-affected zones and low precision, while laser cladding is a better solution.

[0003] A search revealed that Chinese Patent CN215947407U discloses a three-way coaxial laser cladding powder feeding device. In this utility model, the powder feeding hole adopts a tube-type design for easy replacement. The powder feeding tube is made of hard alloy material, which improves the wear resistance of the powder outlet hole. As the powder feeding time increases, the powder outlet hole becomes smoother, ensuring the convergence of the powder beam over a long period of time and ensuring the stability of the laser cladding process.

[0004] When the above-mentioned powder feeding device is in use, powder is fed through the powder feeding hole at the bottom of the conical copper base. However, the position of the powder feeding hole at the bottom of the existing conical copper base is fixed, making it difficult to adjust the powder feeding distance according to the size of the thrust ring, i.e., the distance from the powder feeding hole to the surface of the thrust ring. If the distance is too close, it is easy to scratch the thrust ring; if the distance is too far, the powder bundle will disperse, resulting in a limited range of applications. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a thrust ring laser cladding coaxial powder feeding device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thrust ring laser cladding coaxial powder feeding device, comprising a conical copper base and a first discharge pipe, wherein the top end of the first discharge pipe is fixedly connected to the conical copper base, the conical copper base is provided with multiple through holes, and the first discharge pipe is provided with an adjustment component, the adjustment component comprising a second discharge pipe, a discharge head, two side plates, a lead screw, a stepper motor, a slide rod and a sealing gasket, the second discharge pipe being movably sleeved on the first discharge pipe, and the bottom end of the second discharge pipe being fixedly connected to the discharge head, one side of each of the two side plates being fixedly connected to the second discharge pipe, and one of the side plates being threadedly connected to the lead screw, the stepper motor being fixedly installed at the bottom end of the conical copper base, and the output shaft end of the stepper motor being fixedly connected to the lead screw.

[0007] Furthermore, two support plates are fixedly connected to the outside of the first discharge pipe, and one of the support plates is movably connected to the lead screw via a bearing.

[0008] As can be seen, in the above technical solution, the support plate can provide auxiliary support for the lead screw.

[0009] Furthermore, the bottom end of the slide rod passes through another side plate, and the top end of the slide rod is fixedly connected to another support plate.

[0010] As can be seen, in the above technical solution, the other side plate and the slide bar work together to restrict the rotation of the second discharge pipe.

[0011] Furthermore, the sealing gasket is fixedly installed inside the second discharge pipe, and the inner side of the sealing gasket is in contact with the first discharge pipe.

[0012] As can be seen, in the above technical solution, the sealing gasket can improve the sealing between the second discharge pipe and the first discharge pipe, thereby preventing powder from overflowing through the gap between the second discharge pipe and the first discharge pipe.

[0013] Furthermore, the top of the conical copper base is fixedly connected to multiple guide tubes, and the top of each of the multiple guide tubes is fixedly connected to a connecting plate.

[0014] It can be seen that the above technical solutions are designed to facilitate the installation of external pipes.

[0015] Furthermore, each of the multiple feed pipes is fixedly equipped with an electromagnetic flow regulating valve and an electromagnetic valve, and the multiple electromagnetic valves are respectively located on top of the multiple electromagnetic flow regulating valves.

[0016] Furthermore, multiple alarm lights are fixedly installed on the outer side of the conical copper base, which can serve to alert staff.

[0017] The technical effects and advantages of this utility model are as follows: 1. In this utility model, the powder in the through hole enters the first discharge pipe, and then is discharged through the second discharge pipe and the discharge head. The stepper motor drives the lead screw to rotate, which can drive the two side plates, the second discharge pipe and the discharge head to move downward. Similarly, the stepper motor can reverse to drive the second discharge pipe and the discharge head to move upward. The distance between the discharge head and the thrust ring can be adjusted as needed. The operation is simple, the powder feeding distance is easy to adjust, and the application range is wide. 2. In this utility model, when the solenoid valve is opened, the powder in the external pipe enters the through hole through the connecting plate and the guide pipe, and finally flows out through the discharge head, forming a complete flow channel. When it is not necessary to inject powder, the solenoid valve is closed so that the powder cannot enter the through hole. Similarly, multiple external pipes are installed on multiple connecting plates in sequence, and the powder flowability is detected by the electromagnetic flow regulating valve. The structure is simple and easy to use. Attached Figure Description

Detailed Implementation

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Refer to the instruction manual appendix Figure 1-4This embodiment of a thrust ring laser cladding coaxial powder feeding device includes a conical copper base 1 and a first discharge pipe 2, with the top end of the first discharge pipe 2 fixedly connected to the conical copper base 1. The conical copper base 1 has multiple through holes 10. The first discharge pipe 2 is provided with an adjustment component 4, which includes a second discharge pipe 401, a discharge head 402, two side plates 403, a lead screw 404, a stepper motor 405, a slide rod 406, and a sealing gasket 407. The second discharge pipe 401 is movably sleeved on the first discharge pipe 2, and the bottom end of the second discharge pipe 401 is fixedly connected to the discharge head 402. The two side plates 403 are fixedly connected to the second discharge pipe 401 on opposite sides, and one of the side plates 403 is threadedly connected to the lead screw 404. The stepper motor 405 is fixedly installed at the bottom end of the conical copper base 1, and the output shaft end of the stepper motor 405 is fixedly connected to the lead screw 404.

[0023] Furthermore, two support plates 3 are fixedly connected to the outside of the first discharge pipe 2, and one of the support plates 3 is movably connected to the lead screw 404 through a bearing. The bottom end of the slide rod 406 passes through the other side plate 403, and the top end of the slide rod 406 is fixedly connected to the other support plate 3. The sealing gasket 407 is fixedly installed inside the second discharge pipe 401, and the inner side of the sealing gasket 407 is in contact with the first discharge pipe 2.

[0024] Furthermore, the top of the conical copper base 1 is fixedly connected to multiple guide pipes 5, and the top of each guide pipe 5 is fixedly connected to a connecting plate 6. Electromagnetic flow regulating valves 7 and electromagnetic valves 8 are fixedly installed on each guide pipe 5, and the electromagnetic valves 8 are respectively located on the top of the electromagnetic flow regulating valves 7. Multiple alarm lights 9 are fixedly installed on the outside of the conical copper base 1. The alarm lights 9 can serve to remind the staff.

[0025] The external pipe is connected to the connecting plate 6 by bolts. When the solenoid valve 8 is opened, the powder in the external pipe enters the through hole 10 through the connecting plate 6 and the guide pipe 5, and finally flows out through the discharge head 402, forming a complete flow channel. When powder injection is not required, the solenoid valve 8 is closed to prevent powder from entering the through hole 10. Similarly, multiple external pipes are installed on multiple connecting plates 6 in sequence. The powder flowability is detected by the electromagnetic flow regulating valve 7. The structure is simple and easy to use. When the electromagnetic flow regulating valve 7 detects a blockage in one of the pipes, the alarm light 9 sounds an alarm and stops the powder supply and laser cladding operation for that pipe. It is worth noting that when one pipe is slightly blocked, it directly causes the powder bundle aggregation to deteriorate, which in turn leads to uneven cladding coating thickness and reduced powder utilization.

[0026] The usage method of this embodiment is as follows: In use, the powder in the through hole 10 enters the first discharge pipe 2, and then is discharged through the second discharge pipe 401 and the discharge head 402. The stepper motor 405 is started, driving the lead screw 404 to rotate. The support plate 3 provides auxiliary support for the lead screw 404. Since one side plate 403 is threadedly connected to the lead screw 404, and the other side plate 403 and the slide rod 406 cooperate to restrict the rotation of the second discharge pipe 401, the lead screw 404 can drive both side plates 403. The second discharge pipe 401 and the discharge head 402 move downwards. Similarly, the stepper motor 405 reverses to drive the second discharge pipe 401 and the discharge head 402 to move upwards. The distance between the discharge head 402 and the thrust ring can be adjusted as needed. The operation is simple, the powder feeding distance is easy to adjust, and the application range is wide. At the same time, the sealing gasket 407 can improve the sealing between the second discharge pipe 401 and the first discharge pipe 2, thereby preventing powder from overflowing through the gap between the second discharge pipe 401 and the first discharge pipe 2.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
