Description

Technical Field

[0001] This utility model relates to the field of coating preparation technology, and more specifically, to a laser cladding device. Background Technology

[0002] Laser cladding is a machining technology that uses laser as a heat source to add material to mechanical parts. It uses a high-energy laser beam to melt powder and form a molten pool in the action area on the surface of the part. The molten pool is then rapidly solidified on the surface of the part to form a coating with metallurgical bonding. Due to the rapid cooling and heating process characteristics of laser cladding, the microstructure of the coating is finer and the interior of the coating is denser under non-equilibrium solidification.

[0003] A laser cladding device, disclosed in CN221639534U, includes a powder feeder for providing coating material, a laser emitting device for cladding the coating material onto a workpiece, an ultrasonic vibration device for providing energy to the coating material cladding onto the workpiece, and a moving component for moving the workpiece and the ultrasonic vibration device. The powder feeder and the laser emitting device are located above the workpiece, the ultrasonic vibration device is positioned corresponding to the workpiece, and the moving component is positioned corresponding to the laser emitting device. The workpiece and the ultrasonic vibration device move corresponding to the laser emitting device under the drive of the moving component. The moving component includes a guide rail and a slider positioned corresponding to the guide rail. A support plate is provided on the slider, and the workpiece and the ultrasonic vibration device are located on the support plate.

[0004] The aforementioned patent document has the beneficial effects of homogenizing the composition of the cladding layer, refining the grains, and improving the coating performance. However, the aforementioned device does not have a removal device. After processing, the workpiece still retains a high temperature. Manual removal can easily cause harm to the human body. After removal, it also needs to be placed in the outside environment to cool down, which greatly reduces the processing efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a laser cladding device without a removal device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a laser cladding device, comprising a processing platform and a laser cladding device body. A support plate is provided on the processing platform, and fixed plates are symmetrically distributed on both sides of the support plate. A conveying rod is rotatably connected between the fixed plates. A secondary conveying rod is provided above the conveying rod, and a gear one is fixedly connected to one end of the secondary conveying rod. A gear two is provided below the gear one. An infrared sensor is provided on the inner side wall of the fixed plate, and a cooling collection box is provided at the edge of the processing platform.

[0008] As a preferred embodiment of this utility model, the cooling collection box has fans evenly distributed on both sides of its inner wall, springs evenly distributed at the bottom of its inner wall, and a shock-absorbing plate above the springs.

[0009] As a preferred embodiment of this utility model, the fan is flush with the damping plate, the damping plate is made of fluororubber, and the cooling collection box is generally placed at the outlet.

[0010] As a preferred embodiment of this utility model, the bearing plate is provided with uniformly distributed semi-circular grooves, which are located within the range of the fixed plate, and the conveying rod rotates within the semi-circular grooves.

[0011] As a preferred technical solution of this utility model, the fixing plate is L-shaped, and three evenly distributed drive motors are fixedly connected to the outer wall of the fixing plate. The drive motors are respectively connected to the conveying rods at both ends and in the middle.

[0012] As a preferred embodiment of this utility model, the distance between the auxiliary conveying rod and the conveying rod is adjusted according to the actual thickness of the workpiece being processed, and the rotation directions of the auxiliary conveying rod and the conveying rod are opposite.

[0013] The advantages of this utility model are:

[0014] This invention utilizes the coordination between a drive motor, a conveyor rod, a secondary conveyor rod, a fixing plate, and an infrared sensor. The drive motor rotates the conveyor rod, which transports the workpiece to the bottom of the laser cladding device.

[0024] Please see Figure 1-5 Structural diagram; the present invention provides the following technical solution:

[0025] Specifically, it refers to a laser cladding device, including a processing platform 1 and a laser cladding device body 2. A support plate 3 is provided on the processing platform 1, and fixed plates 4 are symmetrically distributed on both sides of the support plate 3. A conveying rod 6 is rotatably connected between the fixed plates 4. A secondary conveying rod 7 is provided above the conveying rod 6. A gear 8 is fixedly connected to one end of the secondary conveying rod 7. A gear 9 is provided below the gear 8. An infrared sensor 10 is provided on the inner side wall of the fixed plate 4. A cooling collection box 11 is provided at the edge of the processing platform 1.

[0026] It should be noted that the laser cladding device body 2, infrared sensor 10, fan 12, and drive motor 15 are existing technologies. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be described. All of them can be powered by external devices and controlled to turn on and off.

[0027] The cooling collection box 11 has fans 12 evenly distributed on both sides of its inner wall, and springs 13 evenly distributed at the bottom of its inner wall. A damping plate 14 is placed above the springs 13.

[0028] The fan 12 is flush with the shock absorber 14, which is made of fluororubber. The cooling collection box 11 is usually placed at the outlet.

[0029] The support plate 3 is provided with evenly distributed semi-circular grooves 5, which are located within the range of the fixed plate 4, and the conveying rod 6 rotates within the semi-circular grooves 5.

[0030] The semi-circular groove 5 ensures that the conveyor rod 6 will not obstruct the transport of the workpiece.

[0031] The fixing plate 4 is L-shaped, and three evenly distributed drive motors 15 are fixedly connected to the outer wall of the fixing plate 4. The drive motors 15 are respectively connected to the conveyor rods 6 at the beginning and end and in the middle.

[0032] The distance between the two fixing plates 4 is adjusted according to the actual size of the workpiece being processed.

[0033] The distance between the auxiliary conveyor rod 7 and the conveyor rod 6 is adjusted according to the actual thickness of the workpiece being processed, and the rotation directions of the auxiliary conveyor rod 7 and the conveyor rod 6 are opposite.

[0034] The working principle of the extraction device provided by this utility model is as follows:

[0035] Working principle: First, the drive motor 15 is started, which drives the conveyor rod 6 to rotate. The conveyor rod 6 closest to the processing position drives the second gear 9 to rotate, and the second gear 9 drives the first gear 8 to rotate. The first gear 8 drives the auxiliary conveyor rod 7 to rotate. Then, the workpiece is placed in the fixed plate 4, and the workpiece is sent to the processing position by the rotation of the conveyor rod 6. When one end of the workpiece triggers the infrared sensor 10 on the other side, the drive motor 15 stops running. At this time, the workpiece is exactly in the processing position. After processing is completed, the drive motor 15 is started again to convey the workpiece out and drop it into the cooling collection box 11. The fan 12 is then started to cool it down.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
