Description

Technical Field

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

[0002] Laser cladding, also known as laser bonding or laser coating, is a novel surface modification technology. It involves adding a cladding material to the surface of a substrate and using a high-energy-density laser beam to fuse it together with a thin layer on the substrate surface, forming a metallurgically bonded cladding layer on the substrate surface. As an important component of fully mechanized coal mining equipment, the working condition of the cutting tooth directly affects the mining efficiency. By selecting highly wear-resistant powder with strong substrate bonding performance to laser clad a functional layer on the surface of the cutting tooth, it can maintain excellent condition and performance throughout the coal mining process. Its wear resistance and impact resistance can greatly improve the service life of the coal mining machine and increase the efficiency of coal mining operations. To ensure that the cutting tooth can be stably and accurately positioned during the laser cladding process, a clamping and positioning device is required for positioning.

[0003] Chinese patent discloses a clamping device for laser cladding of pick-shaped cutting teeth (authorization announcement number CN214612766U). This patented technology features a base with a support platform, a transition plate on the front side of the support platform, a drive connection to a first motor, and a chuck annularly mounted on the transition plate, rotatably connected to the transition plate. The chuck has a tapered hole. The driving mechanism includes a sliding seat mounted on the support platform, a drive connection to a cylinder, and a tapered shank mounted on the sliding seat, a drive connection to a second motor, with the tapered shank engaging with the tapered hole. This invention enables rapid loading, unloading, and adjustment of workpieces during laser cladding, significantly improving processing efficiency.

[0004] However, most existing cutting teeth are held using a single clamping method, resulting in poor clamping effectiveness and affecting laser cladding operations. For example, the aforementioned comparative document uses only one clamping method. In practical applications, relying on only one clamping method can easily lead to accidents during laser cladding, resulting in poor clamping performance and hindering the laser cladding process. Therefore, those skilled in the art have provided a cutting tooth clamping and positioning device for laser cladding to solve the problems mentioned in the background art. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution for a cutting tooth clamping and positioning device for laser cladding processing: it includes a transition plate 1 and a chuck 3 symmetrically arranged on the upper surface of the transition plate 1. A positioning plate 2 is also installed on the outside of the transition plate 1, and an exhaust channel 11 is symmetrically opened on the outer side of the transition plate 1. An air inlet 21 communicating with the exhaust channel 11 is opened on the inner side of the positioning plate 2. A sealing plate 22 is also provided inside the positioning plate 2, and a vacuum pump 23 is provided below the sealing plate 22 inside the positioning plate 2. An electric push rod 4 is symmetrically arranged on the outer side of the chuck 3, and a positioning groove 31 is opened on the upper surface of the chuck 3. A groove 42 is opened on the inner side of the positioning groove 31, and a clamping plate 41 is provided inside the groove 42. This device uses the clamping plate 41 to clamp and position the cutting tooth when the lower end of the cutting tooth is embedded in the positioning groove 31. At the same time, the operation of the vacuum pump 23 can realize vacuum adsorption, thereby improving the stability of the cutting tooth positioning and making it practical.

[0023] like Figure 2 , Figure 4 and Figure 5 As shown, the exhaust channel 11 is L-shaped inside the transition plate 1, and the upper end of the exhaust channel 11 is connected to the positioning groove 31. The suction end of the vacuum pump 23 is connected to the suction pipe 24, and the upper end of the suction pipe 24 penetrates the upper surface of the sealing plate 22. The lower surface of the positioning plate 2 is symmetrically provided with exhaust holes 25, and the inner side of the positioning plate 2 is in sealed contact with the outer surface of the transition plate 1. With the operation of the vacuum pump 23, after the lower end of the cutting tooth is embedded in the positioning groove 31, the air inside the exhaust channel 11 can enter the interior of the positioning plate 2 through the air inlet 21, and finally be discharged outward through the exhaust hole 25, so as to achieve the purpose of adsorbing and fixing the cutting tooth to be laser cladding, and ensuring its stability.

[0024] like Figure 4 As shown, the chuck 3 also has a fixing groove 43 that communicates with the groove 42. A connecting sleeve is provided on the outside of the clamping plate 41. The telescopic end of the electric push rod 4 is embedded in the connecting sleeve and connected by screws. An adsorption magnet 411 is provided inside the clamping plate 41. A cutting tooth is embedded inside the positioning groove 31. The inner side of the clamping plate 41 is in contact with the outer surface of the cutting tooth. This arrangement allows the clamping plate 41 to move inside the groove 42 by the operation of the electric push rod 4, thereby positioning and clamping the cutting tooth placed inside the positioning groove 31.

[0025] The working principle of this utility model is as follows: When using the cutting tooth clamping and positioning device for laser cladding processing, the lower end of the cutting tooth to be laser cladding is first embedded into the positioning groove 31 opened on the upper surface of the chuck 3. After entering, the operation of the vacuum pump 23 will draw air from the exhaust channel 11 into the positioning plate 2 through the air inlet 21. After entering, the air will be extracted through the air extraction pipe 24 and finally discharged outward through the exhaust hole 25, thereby achieving the purpose of adsorbing and fixing the cutting tooth to be laser cladding, ensuring its stability. After adsorption and fixing, the operation of the electric push rod 4 will cause the clamping plate 41 to move inside the groove 42, thereby positioning and clamping the cutting tooth placed inside the positioning groove 31. At the same time, the adsorption magnet 411 can be used to adsorb the cutting tooth, improving its clamping stability.

Their structure, circuit and control principle are all existing known technologies, and the power control is all external power controller. Therefore, the structure, circuit and control principle of the device are not described in detail here.
