Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a laser cladding device. Background Technology

[0002] Laser cladding, as an advanced material surface modification and additive manufacturing technology, can significantly improve the wear resistance, corrosion resistance, and high temperature resistance of workpieces by forming a cladding layer with special properties on the surface of the substrate. Therefore, it has been widely used in aerospace, mold manufacturing, petrochemical and other fields.

[0003] In the laser cladding process, in order to ensure the accuracy of the cladding trajectory and the forming quality of the cladding layer, the workpiece to be processed needs to be stably fixed on the worktable of the equipment. The clamping of the workpiece is a crucial preparatory step in the entire processing flow, and its fixing effect directly affects the final quality of the subsequent laser cladding.

[0004] However, many existing laser cladding equipment uses traditional mechanical methods such as manual bolt clamps and screw clamps to fix workpieces. These clamping methods are cumbersome, requiring manual tightening or adjustment of each bolt individually. This is not only labor-intensive but also inefficient, failing to meet the demands of modern production for high efficiency and automation. Furthermore, this manual clamping method makes it difficult to guarantee the uniformity and stability of the clamping force. Differences between operators and operator fatigue can lead to inaccurate workpiece positioning or slight loosening during processing, thus affecting cladding accuracy and yield.

[0005] Therefore, this utility model proposes a laser cladding device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing laser cladding equipment, such as the clamping device being mostly manually operated, low clamping efficiency, and difficulty in ensuring the stability of clamping force, which affects the cladding accuracy, this utility model aims to provide a laser cladding equipment with an improved structure that can effectively solve the above problems.

The first workbench is disposed on the upper surface of the base plate, the second workbench is disposed on the upper surface of the first workbench, and the protective cover is installed on the base plate and covers the outside of the first and second workbench.

[0013] Preferably, the laser cladding equipment further includes a cleaning component, which is fixed to the upper surface of the first worktable.

[0022] 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.

[0023] Please refer to Figures 1 to 4This utility model provides a laser cladding device, which aims to solve the problems in the prior art where the low degree of automation of the clamping device leads to low workpiece fixing efficiency and the failure to effectively clean up debris during the cladding process.

[0024] like Figures 1 to 3 As shown, a laser cladding device includes a support assembly 1, a fixing and clamping assembly 3, an adjustment assembly 4, and a cleaning assembly 2. The support assembly 1 provides the mounting base for the entire device and includes a base plate 101. A first worktable 102 is disposed on the upper surface of the base plate 101, and a second worktable 103 is disposed on the upper surface of the first worktable 102. A protective cover 104 is also mounted on the base plate 101 and covers the first worktable 102 and the second worktable 103. The fixing and clamping assembly 3 is mounted on the support assembly 1 and is used to fix the workpiece placed on the second worktable 103. The fixed clamping assembly 3 includes a lifting cylinder 309, and a main connector 308 is fixedly connected to the outer wall of the lifting cylinder 309. The main connector 308 is connected to one end of the auxiliary connector 305 through a connecting plate 307. The connecting plate 307 is fixedly connected to the main connector 308 and the auxiliary connector 305 respectively through bolts 306. The other end of the auxiliary connector 305 is rotatably connected to an L-shaped connecting rod 304. The L-shaped connecting rod 304 is fixedly connected to the bottom of the clamping plate 301. The clamping plate 301 is slidably fitted to the slide rail 302. The fixed clamping assembly 3 also includes a slide rod 303, and the L-shaped connecting rod 304 is slidably connected to the slide rod 303.

[0025] Adjustment component 4 is mounted on support component 1 and is used to adjust the position of laser cladding nozzle 403. Please refer to [reference needed]. Figure 1 The adjustment component 4 includes a mounting housing 401, which houses a lead screw 402. A slip ring 404 is threaded onto the lead screw 402, and a laser cladding nozzle 403 is fixedly connected to the outer wall of the slip ring 404. When it is necessary to adjust the processing height of the laser cladding nozzle 403, the lead screw 402 is driven to rotate by a drive device. Since the slip ring 404 and the lead screw 402 are threadedly connected, the rotational motion of the lead screw 402 is converted into the linear motion of the slip ring 404, thereby driving the laser cladding nozzle 403 fixed on the slip ring 404 to move up and down along the axis of the lead screw 402. This threaded transmission structure between the lead screw 402 and the slip ring 404 ensures the stability and positioning accuracy of the laser cladding nozzle 403 in the vertical direction.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 1 and Figure 2In order to construct a stable and safe working platform, the support component 1 includes a base plate 101, a first workbench 102 disposed on the upper surface of the base plate 101, a second workbench 103 disposed on the upper surface of the first workbench 102, and a protective cover 104 installed on the base plate 101 and covering the first workbench 102 and the second workbench 103.

[0027] As another preferred embodiment, please refer to Figure 4 In order to clean the processing area, the equipment also includes a cleaning component 2, which is fixed to the upper surface of the first workbench 102. The cleaning component 2 includes a first support rod 201, a second support rod 204 and a gas nozzle 203, which are fixed to the first workbench 102. The first support rod 201 is connected to the second support rod 204 through a first positioning pin 202. The gas nozzle 203 is rotatably connected to the second support rod 204 through a rotary joint 205. In order to adjust the angle of the gas nozzle 203, the cleaning component 2 also includes a positioning pin 206 provided on the rotary joint 205 and a limiting hole 207 opened on the second support rod 204. The positioning pin 206 and the limiting hole 207 are inserted and engaged.

[0028] As another preferred embodiment, please refer to Figure 3 In order to improve the guiding stability of the L-shaped link 304 during movement, the fixed clamping assembly 3 also includes a slide bar 303, to which the L-shaped link 304 is slidably connected.

[0029] The working principle of the laser cladding equipment of this utility model is as follows: When the workpiece needs to be processed, the workpiece is first placed on the upper surface of the second worktable 103 of the support assembly 1. Then, the lifting cylinder 309 of the fixed clamping assembly 3 is driven to move. The lifting cylinder 309 drives the main connector 308, which is fixedly connected to its outer wall, to move. The main connector 308 drives the auxiliary connector 305 to move through the connecting plate 307 and bolt 306. The auxiliary connector 305 then drives the L-shaped connecting rod 304, which is rotatably connected to it, to swing. Under the guidance of the slide rod 303, the L-shaped connecting rod 304 drives the clamping plate 301, which is fixedly connected to its bottom, to move along the slide rail 302, thereby realizing the rapid clamping and fixing of the workpiece.

[0030] After the workpiece is fixed, the lead screw 402 in the adjustment assembly 4 is driven to rotate according to the processing requirements. The slip ring 404, which is threaded with the lead screw 402, converts the rotational motion of the lead screw 402 into linear motion, and drives the laser cladding nozzle 403 fixed on its outer wall to move vertically to a suitable processing height. Then the laser cladding nozzle 403 is started to perform the cladding operation.

[0031] During or after the cladding process, the cleaning component 2 is activated, and gas is sprayed from the gas nozzle 203 to clean the slag and debris on the workpiece surface. If the cleaning angle needs to be adjusted, the gas nozzle 203 and the rotary joint 205, which are rotatably connected to the second support rod 204, can be rotated, and the positioning pin 206 set on the rotary joint 205 can be pulled out, aligned with the different limiting holes 207 on the second support rod 204, and inserted to adjust and fix the spray angle. The entire process is carried out under the protection of the protective cover 104 to ensure the safety of operation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
