Description

Technical Field

[0001] This utility model relates to the field of gear repair technology, and more specifically, to gear cladding repair equipment. Background Technology

[0002] Laser cladding technology refers to a process in which a selected coating material is placed on the surface of a substrate using different filler methods. The material is then irradiated with a laser, causing it and a thin layer on the substrate surface to melt simultaneously and solidify rapidly. This results in a surface coating with extremely low dilution and a metallurgical bond with the substrate material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the substrate material surface. Gears are common components in mechanical transmissions, and they typically experience significant wear during transmission, necessitating the use of laser cladding technology for repair.

[0003] Among them, the patent with publication number CN219385330U discloses a laser cladding clamping device for gear repair, including a base plate. The base plate has mounting grooves on both the front and rear sides. The inner cavities of the front and rear mounting grooves are respectively welded with mounting vertical plates and guide slide rods. The right side of the mounting vertical plate is connected to a drive motor by bolts. The output end of the drive motor is fixedly connected to a threaded rod. Mounting frames are movably sleeved on both the left and right sides of the threaded rod and the guide slide rod. The top of the mounting frame extends through to the top of the base plate and is connected to a support rod by bolts. The opposite sides of the left and right mounting blocks are movably connected to clamping cones by bearings.

[0004] When in use, this structure, through the cooperation of the second clamping plate, threaded rod, mounting bracket, drive motor, clamping cone, electric push rod and the first clamping plate, can easily clamp and fix vertical or horizontal gears, facilitating comprehensive gear repair. However, this structure is not easy to quickly adjust the repair position during use, and alloy materials are also prone to splashing during the repair process. Utility Model Content

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By setting up positioning and repair components, compared with existing technologies, the design of chuck, teeth and arc groove can be adapted to gear outer diameters of different specifications. With the anti-slip protective pad in the arc groove, it can not only avoid indentation on the gear surface through elastic contact, but also ensure that the gear position is stable and does not shift during the repair process.

[0012] The protective cover is installed on the outside of the chuck, which can effectively block the high-temperature welding slag spatter generated during the laser cladding process and improve the safety of the operation. The reinforced guide tube at the bottom of the nozzle optimizes the delivery path of the alloy material and forms a concentrated jet stream, which reduces material spatter loss and allows the alloy material to accurately cover the damaged area of ​​the gear, improving the material utilization rate and surface smoothness of the cladding repair.

[0019] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figures 1-4 The gear cladding repair equipment shown uses a positioning repair component on the base 1 to set the output parameters of the laser, such as laser power, pulse frequency, and scanning speed, through the frequency controller 8 to adapt to the gear material and degree of damage. An external high-pressure device delivers alloy material to the reinforcing guide pipe 14, which is then concentrated by the nozzle 7 and sprayed onto the surface of the gear to be repaired with high concentration. The specific structure of the component is as follows.

[0021] The positioning and repair component includes a motor 2 set on the top of the base 1, a chuck 3 set on the top of the motor 2, a number of position-adjustable teeth 4 set on the chuck 3, and an arc groove opened on one side of each tooth 4.

[0022] The top of the chuck 4 is equipped with a laser 6 for processing, and the bottom of the laser 6 is equipped with a nozzle 7 for focusing the alloy material. The nozzle 7 is equipped with a reinforcing guide tube 14 for guiding the flow. The top of the motor 2 is connected to a protective cover 13, which covers the outside of the chuck 3. Multiple chuck teeth 4 are distributed around the circumference of the axis of the chuck 3. Multiple arc grooves are equipped with protective pads 5 for anti-slip. The top of the laser 6 is equipped with a frequency controller 8.

[0023] Specifically, as shown in the attached document Figure 1 , 2As shown in Figures 3 and 4, during the cladding repair of damaged gears, the gear is placed between the various locking teeth 4. The outer side of the gear is positioned using the arc groove. The position of each locking tooth 4 is adjusted by the chuck 3 so that the locking teeth 4 can be locked onto the outer side of the gear. The protective pad 5 improves the stability of the locking teeth 4 in clamping the gear and also prevents indentations on the gear surface when the locking teeth 4 clamp the gear. The laser frequency emitted by the laser 6 is adjusted by the frequency controller 8. The external high-voltage equipment delivers alloy material to the nozzle 7. The nozzle 7 concentrates the material and then heats it with the laser, allowing the alloy material to repair the damaged area of ​​the gear. The protective cover 13 effectively prevents the spatter of welding slag generated during the repair process.

[0024] A frequency controller 8 is provided on one side of the motor 2. The frequency controller 8 is mounted on the base 1 by bolts. A vertical plate 9 is provided on the top of the frequency controller 8. A first electric slide rail 10 with adjustable position is slidably connected to the vertical plate 9. A second electric slide rail 11 is mounted on the first electric slide rail 10 by bolts. A connecting frame 12 with adjustable position is slidably connected to the second electric slide rail 11. The connecting frame 12 is mounted on one side of the laser 6 by bolts.

[0025] Specifically, as shown in the attached document Figure 1 , 2 As shown in Figure 4, the first electric slide rail 10 starts and adjusts the position of the second electric slide rail 11 and the connecting frame 12 to achieve the function of horizontal adjustment of the laser 6. The second electric slide rail 11 drives the connecting frame 12 to move up and down to achieve the function of vertical adjustment of the laser 6, which makes it easy to repair the gear at different positions.

[0026] The specific working principle is as follows: the gear to be repaired is placed between the teeth 4 of the chuck 3, and the radial adjustment mechanism of the chuck 3 drives the teeth 4 to move, so that the arc surface of the teeth 4 fits tightly with the outer circle surface of the gear. The anti-slip protective pad 5 fills the gap through elastic deformation, preventing indentations on the gear surface while ensuring a firm clamping.

[0027] Start the first electric slide rail 10, which drives the second electric slide rail 11 and the laser 6 to move laterally along the vertical plate 9 to complete the horizontal position calibration. Drive the connecting frame 12 to rise and fall vertically through the second electric slide rail 11, so that the nozzle 7 at the bottom of the laser is accurately aligned with the area of ​​the gear to be repaired.

[0028] The output parameters of the laser, such as laser power, pulse frequency, and scanning speed, are set by the frequency controller 8 to match the gear material and degree of damage. The external high-pressure equipment delivers the alloy material to the reinforced guide pipe 14, which is then concentrated by the nozzle 7 and sprayed onto the surface of the gear to be repaired with high concentration.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
