[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that it is difficult to control the flatness of welding in the existing welding device for mechanical equipment parts during welding, and the welding point needs to be polished and cleaned separately afterwards, which makes the processing operation more troublesome.

[0006] In order to solve the above problems, the present invention provides a mechanical equipment parts welding device, comprising: A base, a welding head is installed on the top of one side of the base, a support frame is installed on the upper end of the base, and a mounting seat is installed on the inner side of the support frame; A clamping block, wherein two clamping blocks are provided, a first electric push rod is installed on one side of the mounting seat, the first electric push rod is coaxially rotatably mounted with one of the clamping blocks, a first drive motor is installed on the other side of the mounting seat, and an output end of the first drive motor is coaxially fixed with the other clamping block; A grinding disc is rotatably mounted on the upper end of the base, and a transmission assembly is installed between the grinding disc and the output end of the clamping block.

The lower end of the grinding disc extends to the lower side of the cooling water surface. During the rotation of the grinding disc, the cooling water can be used to evenly cool the grinding disc, so that when the grinding disc contacts the welding layer of the part, it can play a certain heat exchange role on the welding layer.

[0020] The first implementation method: The present invention provides a mechanical equipment parts welding device, please refer to Figure 1-8 , including a base 1, a clamping block 5 and a grinding disc 11.

[0021] Among them, a welding head 2 is installed at the top of one side of the base 1, a support frame 3 is installed at the upper end of the base 1, a mounting seat 4 is installed on the inner side of the support frame 3, two clamping blocks 5 are provided, a first electric push rod 6 is installed on one side of the mounting seat 4, the first electric push rod 6 is coaxially rotatably installed with one of the clamping blocks 5, a first drive motor 7 is installed on the other side of the mounting seat 4, the output end of the first drive motor 7 is coaxially fixed with the other clamping block 5, a grinding disc 11 is rotatably installed at the upper end of the base 1, and a transmission assembly is installed between the grinding disc 11 and the output end of the clamping block 5.

[0022] The mechanical equipment parts welding device is arranged through the cooperation of the transmission component and the grinding disc 11. The first drive motor 7 drives the clamping block 5 to rotate the part. At the same time, the transmission cooperation of the transmission component causes the grinding disc 11 to rotate relative to the part, thereby maintaining the grinding effect on the welding point of the part during the rotation welding process of the part, eliminating the need for subsequent separate grinding and cleaning operations, thereby improving processing efficiency.

[0023] Regarding the transmission components, specifically, Figure 3 It is shown that the transmission assembly includes a transmission gear 1 8, a transmission gear 2 9 and a transmission gear 3 10. The transmission gear 1 8 is coaxially fixed with the output shaft of the clamping block 5, the transmission gear 3 10 is coaxially fixed with the grinding disc 11, the transmission gear 2 9 is rotatably mounted on the upper end of the base 1, and is meshed between the transmission gear 1 8 and the transmission gear 3 10. The diameter of the transmission gear 1 8 is larger than the diameter of the transmission gear 3 10.

[0024] Based on the coordination setting of the above structure, the first drive motor 7 drives the clamping block 5 to rotate the part, while through the transmission coordination of the transmission gear 1 8, the transmission gear 2 9 and the transmission gear 3 10, and the diameter of the transmission gear 1 8 is larger than the diameter of the transmission gear 3 10, the grinding disc 11 rotates rapidly relative to the part, and the rotation direction of the grinding disc 11 is the same as the rotation direction of the part, thereby effectively grinding the welding point of the part during the rotation welding process of the part.

[0025] Among them, in order to enable the welding device to meet the welding requirements of parts with different diameters, a second drive motor 12 is installed on the side end of the base 1, and the output shaft of the second drive motor 12 coincides with the central axis of the grinding disk 11, and a connecting rod 13 is installed between the output shaft of the second drive motor 12 and the mounting seat 4, and the mounting seat 4 is slidably installed on the inner side of the support frame 3. When in use, according to the actual diameter of the parts, the second drive motor 12 is used to drive the mounting seat 4 to rotate with the two parts to be welded to be close to the grinding disk 11.

[0026] like Figure 7 and Figure 8 Shown, Figure 7 The diameter of the part in is d1, Figure 8 The diameter of the part is d2, where d1>d2. It should be further explained that the integrated welding and polishing structural design in this scheme is only applicable to parts with cylindrical welding surfaces.

[0027] Among them, a second electric push rod 15 is installed on the side of the base 1 away from the second drive motor 12, and the output end of the second electric push rod 15 is coaxially rotatably installed with the transmission gear three 10. A limiting slide rod 14 is installed at the center of the end of the transmission gear three 10 away from the second electric push rod 15. A limiting slide hole 16 matched with the limiting slide rod 14 is provided on the central axis of the transmission gear three 10. The limiting slide rod 14 is non-cylindrical, and the second electric push rod 15 is used to move the grinding disc 11 to the two parts to be welded.

[0028] like Figure 1 and Figure 2 As shown, a water tank 17 is provided at the upper end of the base 1, and cooling water is contained inside the water tank 17. The lower end of the grinding disc 11 extends to the lower side of the cooling water surface.

[0029] Based on the coordinated arrangement of the above structure, during the rotation of the grinding disc 11, cooling water can be used to evenly cool the grinding disc 11, so that when the grinding disc 11 contacts the welding layer of the part, it can play a certain heat exchange role on the welding layer. In addition, the cooling water can wash away the welding slag attached to the surface of the grinding disc 11.

[0030] Furthermore, a wiper plate 18 is installed on the inner wall of the base 1 at one side away from the welding head 2 , and the wiper plate 18 is fitted and clamped on the outer side of the grinding disc 11 .

[0031] During the rotation of the grinding disc 11 , the provided scraper 18 can be used to scrape off water stains and welding slag attached to the surface of the grinding disc 11 , so as to ensure that the grinding disc 11 has a stable grinding effect on the welding layer of the part.

[0032] In addition, a detection device 19 is installed on the inner side of the mounting seat 4, and the detection end of the detection device 19 is arranged toward one side of the clamping block 5; the detection device 19 can select conventional welding layer quality detection instruments in the prior art, such as detection equipment for detecting the thickness of the welding layer, detection equipment for detecting the surface roughness of the welding layer, etc.

[0033] Working principle: two parts to be welded are clamped between two clamping blocks 5, and the grinding disc 11 is moved to the two parts to be welded by the second electric push rod 15, and then the second drive motor 12 is used to drive the mounting seat 4 to rotate the two parts to be welded close to the grinding disc 11. At this time, the welding head 2 can be used for welding, and the first drive motor 7 is used to drive the clamping block 5 to rotate with the parts. By controlling the speed of the first drive motor 7, a thin welding layer is formed at the part to be welded when the welding head 2 rotates one circle of the part. The first drive motor 7 is used to drive the part to rotate multiple circles to achieve multi-layer welding, and avoid high-temperature deformation caused by long local welding time of the part; in addition, when the first drive motor 7 drives the clamping block 5 to rotate with the part, the grinding disc 11 is rotated rapidly relative to the part through the transmission cooperation of the transmission gear 1 8, the transmission gear 2 9 and the transmission gear 3 10, and the rotation direction is the same as the rotation direction of the part, so as to maintain the continuous grinding effect on the welding part of the part during the multi-layer welding process of the part, and the welding layer is qualified through the detection equipment 19.

[0034] Compared with the prior art, the present solution uses the transmission cooperation of the transmission gear 1 8, the transmission gear 2 9 and the transmission gear 3 10, and the diameter of the transmission gear 1 8 is larger than the diameter of the transmission gear 3 10. The first drive motor 7 drives the clamping block 5 to rotate with the part, and at the same time, the grinding disc 11 rotates rapidly relative to the part, and the rotation direction of the grinding disc 11 is the same as the rotation direction of the part, so that the welding part of the part is effectively polished during the rotation welding process of the part. Compared with the prior art, the present invention installs a second drive motor 12 at the side end of the base 1, the output shaft of the second drive motor 12 coincides with the central axis of the grinding disc 11, and a connecting rod 13 is installed between the output shaft of the second drive motor 12 and the mounting seat 4, and the mounting seat 4 is slidably mounted on the inner side of the support frame 3. When in use, the second drive motor 12 can be used to drive the mounting seat 4 to rotate with two parts to be welded to the grinding disc 11 according to the actual diameter of the parts, so that the welding device can meet the welding requirements of parts with different diameters. Compared with the prior art, the present invention provides a water storage tank 17 at the upper end of the base 1, and cooling water is contained inside the water storage tank 17. The lower end of the grinding disc 11 extends to the lower side of the cooling water surface. During the rotation of the grinding disc 11, the cooling water can be used to evenly cool the grinding disc 11, so that when the grinding disc 11 contacts the welding layer of the part, it can play a certain heat exchange role on the welding layer. In addition, the cooling water can wash away the welding slag attached to the surface of the grinding disc 11, and during the rotation of the grinding disc 11, the provided scraper 18 can be used to further scrape off the water stains and welding slag attached to the surface of the grinding disc 11, so as to ensure the stable grinding effect of the grinding disc 11 on the welding layer of the part. Compared with the prior art, this solution controls the rotation speed of the first drive motor 7 so that a thin welding layer is formed on the part to be welded every time the welding head 2 rotates one circle of the part. The first drive motor 7 is used to drive the part to rotate multiple circles to achieve multi-layer welding, thereby avoiding high-temperature deformation caused by long local welding time of the part, thereby effectively improving the welding quality.

[0035] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
