DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0017] Embodiment 1: Refer to Figures 1-3 , the CNC surfacing device for the middle trough of the scraper conveyor includes a first frame 1. A plurality of support legs 14 are provided at the bottom of the first frame 1. A first lead screw assembly 2 is provided on the first frame 1. A second frame 3 is provided on the first frame 1. The second frame 3 is connected to the first lead screw assembly 2. A second lead screw assembly 4 is provided on the second frame 3. A connecting seat 5 is provided on the second frame 3. The second lead screw assembly 4 is connected to the connecting seat 5. Fixed rods 6 are provided on both sides of the bottom of the connecting seat 5. Welding assemblies 7 are provided at both fixed rods 6. Adjusting mechanisms are provided between the two fixed rods 6 and the two welding assemblies 7. The adjusting mechanism includes a connecting rod 8 placed on one side of the fixed rod 6. The connecting rod 8 penetrates the fixed rod 6 and is provided with a clamping head 9. A nut 10 is threadedly connected to the connecting rod 8. The welding assembly 7 is clamped on the clamping head 9.

[0018] The provided connecting rod 8 and nut 10 enable the connecting rod 8 to rotate relative to the fixed rod 6, allowing the angle of the clamping head 9 relative to the fixed rod 7 to be adjusted, thereby enabling the direction of the welding assembly 7 to be adjusted, making it easier for the welding torch of the welding assembly 7 to align with the outer side of the workpiece.

[0019] Combined with the attached Figures 1-2 As can be seen, screw rod connection blocks 15 are provided at the bottom of both the connecting seat 5 and the second frame 3. The first screw rod assembly 2 and the second screw rod assembly 4 are both threadedly penetrated through the screw rod connection blocks 15, and servo motors are provided at both the first screw rod assembly 2 and the second screw rod assembly 4.

[0020] After placing the workpiece to be surfacing near the equipment, start the servo motors at the first screw rod assembly 2 and the second screw rod assembly 4. After the welding assembly 7 reaches the position of the workpiece, by rotating the nut 10 and using a feeler gauge to adjust the distance between the welding assembly 7 and the workpiece, and then through the transmission of the first screw rod assembly 2 and the second screw rod assembly 4, control the position of the welding torch on the welding assembly 7 to achieve full - range surfacing treatment of the inner layer of the middle trough of the scraper conveyor. Moreover, the workpiece is located outside the equipment, thus reducing the difficulty of picking up, placing, and arranging the workpiece.

[0021] Embodiment 2: Optimized on the basis of Embodiment 1, referring to Figures 1-3 , both of the two fixed rods 6 are provided as hollow tubes. Reinforcement blocks 11 are provided on both of the two fixed rods 6. The two connecting rods 8 on the two fixed rods 6 penetrate through the two reinforcement blocks 11. Slide rails 12 are provided on both the first frame 1 and the second frame 3. Plastic drag chains 13 are provided in both of the two slide rails 12. The first frame 1 and the second frame 3 are perpendicularly arranged. A wear - resistant coating is provided on one side of the bottom of the second frame 3.

[0022] Setting the fixed rod 6 as a hollow tube reduces the weight of the fixed rod 6, thereby reducing the weight at the second frame 3, making the gravity received by the first frame 1 lower, and thus greatly reducing the wear at the connection between the first frame 1 and the second frame 3. The provided wear - resistant coating is formed by nitriding treatment, making the bottom of the second frame 3 more wear - resistant. The provided reinforcement blocks 11 make the connection between the fixed rod 7 and the connecting rod 8 not easily deformed, thereby extending the service life of the device.

[0023] The above - mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
