Description
Technical Field
[0001] This utility model relates to the field of cladding technology, specifically to a laser cladding device for the surface of a piston rod that prevents splashing. Background Technology
[0002] As a core component of hydraulic cylinders, pneumatic cylinders, and other equipment, the surface quality of the piston rod directly affects the operating accuracy, sealing performance, and service life of the equipment. To improve the piston rod's key properties such as wear resistance and corrosion resistance, laser cladding technology is widely used in piston rod surface treatment processes. This technology uses a high-energy laser beam to simultaneously melt the cladding material and a thin layer on the piston rod surface, which then rapidly solidifies to form a dense cladding layer. This effectively improves the piston rod's surface properties and extends its service life.
[0003] However, in actual production, some piston rods have grooved structures on their outer surface to meet specific assembly or functional requirements. When using traditional laser cladding equipment to clad these grooved piston rods, the significant height difference between the bottom of the groove and the outer surface of the piston rod causes a drastic change in the energy distribution of the laser beam as the cladding nozzle moves to the junction of the groove and the outer surface, disrupting the stability of the molten pool. The molten metal material generates numerous sparks under the influence of laser energy, and these sparks are easily scattered in all directions due to airflow disturbances and energy fluctuations caused by the height difference between the groove and the outer surface.
[0004] The flying sparks can cause ablation damage to surrounding equipment parts and tooling fixtures, shortening the maintenance cycle and service life of the equipment. More seriously, if the sparks come into contact with flammable materials or operators in the workshop, they may cause fires or personal safety accidents, posing a great threat to production safety.
[0005] Therefore, it is necessary to provide a laser cladding device for the piston rod surface to prevent splashing and solve the above problems. Utility Model Content
[0006] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a laser cladding device for piston rod surface to prevent splashing, so as to solve the problems mentioned in the background art.
[0007] The technical solution adopted by this utility model to solve its technical problem is: a laser cladding device for piston rod surface to prevent splashing, used to clad the piston rod. The outer surface of the piston rod has several spaced grooves. It includes a cladding machine body, a cladding robotic arm, a surrounding plate and a linear push rod. The cladding robotic arm is located on one side of the cladding machine body. The linear push rod is installed in the cladding machine body. The surrounding plate is slidably installed in the cladding machine body. The bottom of the surrounding plate is fixedly connected to the telescopic end of the linear push rod.
[0008] Furthermore, the enclosure is integrally formed, hollow in the center, and has observation windows on the front and rear sides. The observation windows are closed structures, with a left side panel and a right side panel on the left and right sides, respectively. The upper surfaces of the left and right side panels are arc-shaped, and the height of the observation windows is higher than the left and right side panels.
[0009] Furthermore, the cladding machine body has a cladding platform, and a placement groove is provided on the cladding platform. The surrounding plate is slidably connected to the placement groove. The linear push rod is provided with two telescopic rods that extend and retract vertically. One telescopic rod of the linear push rod rests against the bottom front end of the enclosure, and the other telescopic rod of the linear push rod rests against the bottom rear end of the enclosure.
[0010] Furthermore, the cladding machine body also has a boss, the outer surface of which is enclosed by the inner surface of the surrounding plate, and the top of the boss gradually rises from left to right.
[0011] Furthermore, the top of the cladding machine body is provided with a feeding port, which is located on the left side of the boss. The surrounding plate is located between the feeding port and the boss. The bottom of the feeding port is an inclined section that gradually decreases from back to front. A chip collection plate is provided below the inclined section. The chip collection plate is installed on the cladding machine body and is directly below the cladding table.
[0012] Furthermore, the cladding machine body also has a main shaft and a tailstock, with one end of the piston rod connected to the main shaft and the other end connected to the tailstock.
[0013] The beneficial effects of this utility model are: The piston rod surface laser cladding equipment provided by this utility model can cover the piston rod by installing a sliding enclosure. During laser cladding, the sparks that splash are blocked by the inner surface of the enclosure and fall onto the boss, which improves the safety of operation, effectively blocks the splash of sparks, and avoids the sparks from coming into contact with flammable materials or operators in the workshop. By setting up the boss, the rise of the enclosure plate can be guided. On the other hand, the top of the boss is lower on the left and higher on the right. It works in conjunction with the inclined part of the discharge port, which is lower in the front and higher in the back. This allows the debris on the top of the boss to fall into the discharge port first due to gravity, and then into the debris collection tray. The debris can be automatically cleaned and recycled during each cladding process, saving labor costs.
[0014] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0016] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0018] like Figure 1-5 As shown, the present invention provides a technical solution: a laser cladding device for the surface of a piston rod to prevent splashing, used to clad the piston rod 5. The outer surface of the piston rod 5 has several spaced grooves. The device includes a cladding machine body 1, a cladding robotic arm 2, a surrounding plate 3, and a linear push rod 4. The cladding robotic arm 2 is located on one side of the cladding machine body 1. The linear push rod 4 is installed inside the cladding machine body 1. The surrounding plate 3 is slidably installed inside the cladding machine body 1. The bottom of the surrounding plate 3 is fixedly connected to the telescopic end of the linear push rod 4.
[0019] The enclosure panel 3 is integrally formed, with a hollow center and observation windows 31 on the front and rear sides. The observation windows 31 are closed structures, with a left side panel 32 and a right side panel 33 on the left and right sides respectively. The upper surfaces of the left side panel 32 and the right side panel 33 are arc-shaped, and the height of the observation windows 31 is higher than that of the left side panel 32 and the right side panel 33.
[0020] The cladding machine body 1 has a cladding table 14, and a placement groove 141 is provided on the cladding table 14. The surrounding plate 3 is slidably connected to the placement groove 141. The linear push rod 4 is equipped with two telescopic rods 41 that extend and retract vertically. One of the telescopic rods 41 of the linear push rod 4 rests against the bottom front end of the enclosure 3, and the other telescopic rod 41 of the linear push rod 4 rests against the bottom rear end of the enclosure 3.
[0021] The cladding machine body 1 also has a boss 142, the outer surface of which is enclosed by the inner surface of the enclosure plate 3, and the top of the boss 142 gradually rises from left to right.
[0022] The top of the cladding machine body 1 is provided with a feeding port 143, which is located to the left of the boss 142. The surrounding plate 3 is located between the feeding port 143 and the boss 142. The bottom of the feeding port 143 is an inclined part 1431 that gradually decreases from back to front. A chip collection plate 13 is provided below the inclined part 1431. The chip collection plate 13 is installed on the cladding machine body 1 and is directly below the cladding table 14.
[0023] The cladding machine body 1 also has a main shaft 11 and a tailstock 12. One end of the piston rod 5 is connected to the main shaft 11 and the other end is connected to the tailstock 12.
[0024] In one embodiment, the device uses the following operating principle
[0025] Specifically, the piston rod 5 is installed between the main shaft 11 and the tailstock 12. The linear push rod 4 is started, and the motor drives the telescopic rod 41 to move upward, which in turn moves the enclosure 3 upward. When the telescopic rod 41 reaches the upper limit position, the observation window 31 and the piston rod 5 are at the same horizontal position. At this time, the main shaft 11 is started to rotate, and then the cladding robot arm 2 is operated to clad the piston rod 5. The sparks generated by the cladding are blocked by the inner surface of the enclosure 3 and the observation window 31, and the generated debris falls into the top surface of the boss 142. After the cladding is completed, the extension rod 41 is controlled to drive the surrounding plate 3 to descend. During the descent, when the lowest point of the boss 142 is higher than the lowest point of the left side plate 32, the debris on the boss 142 will fall into the discharge port 143 due to gravity, and then fall into the chip collection plate 13 along the inclined part 1431 to clean up the generated debris. When the telescopic rod 41 is at its lower limit position, part of the enclosure 3 is located in the placement groove 141. At this time, the piston rod 5 after being clad is taken out, thus completing the cladding operation.
[0026] In summary, the device can enclose the piston rod 5 by installing the sliding enclosure 3. During laser cladding, the sparks splashing are blocked by the inner surface of the enclosure 3 and fall onto the boss 142, which improves the safety of operation, effectively blocks the splashing of sparks, and prevents the sparks from coming into contact with flammable materials or operators in the workshop. By providing a boss 142, the rise of the enclosure 3 can be guided. On the other hand, the top of the boss is lower on the left and higher on the right. This works in conjunction with the inclined part 1431 of the discharge port 143, which is lower at the front and higher at the back. This allows the debris on the top of the boss 142 to fall into the discharge port 143 first due to gravity, and then into the chip collection tray 13. This can automatically clean and recycle the debris during each cladding process, saving labor costs.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
