[0026] The technical solution provided by the present invention is further described below in conjunction with the accompanying drawings and according to specific implementation methods.

[0027] like Figures 1 to 10As shown, a welding process tooling for composite silver-based wear-resistant materials includes a welding mechanism 1, and the welding mechanism 1 includes a welding bracket 101. A welding rod 102 is fixedly installed at the front end of the welding bracket 101. A grinding mechanism 2 and a supporting mechanism 3 are hinged at the front end of the welding bracket 101. An electric welding head 105 is fixedly installed at the front end of the welding rod 102. A gas welding head 106 is laterally slidably installed at the front end of the welding rod 102. The gas welding head 106 is slidably matched with the outer wall of the electric welding head 105. A welding head guard plate 103 is fixedly installed at the front end of the welding rod 102. The welding head guard plate 103 is in contact with the outer wall of the electric welding head 105, so as to facilitate the use of different welding methods according to different welding requirements. An exhaust port 109 is fixedly installed at the bottom of the welding rod 102 for removing the smoke generated during welding, so that the staff can see the welding place clearly.

[0028] like Figures 1 to 10 As shown, the grinding mechanism 2 includes an upper cover plate 201, which is hinged on the top of the welding bracket 101, and an adjusting rod 202 is installed in the upper cover plate 201 for transverse sliding. An adjusting motor 211 is fixedly installed in the upper cover plate 201, and a screw is fixedly installed at the front end of the adjusting motor 211. The screw at the front end of the adjusting motor 211 cooperates with the screw rod of the adjusting rod 202, and a connecting rod 203 is installed in the adjusting rod 202 for transverse sliding. A compression spring is fixedly installed between the adjusting rod 202 and the connecting rod 203, and a hollow support rod 204 is rotatably installed at the front end of the connecting rod 203, and supporting short rods 207 are rotatably installed at both ends of the hollow support rod 204, and a first grinding wheel 208 and a second grinding wheel 209 are rotatably installed on the supporting short rods 207 at both ends, respectively, and the first grinding wheel 208 and the second grinding wheel 209 are fixedly installed with pulleys. 8 is connected with the second grinding wheel 209 by a transmission belt 210. The first grinding wheel 208 and the second grinding wheel 209 are used to grind the surface of the welding component. At the same time, the first grinding wheel 208 or the second grinding wheel 209 can be selected to grind the component according to the surface shape of the component to remove impurities on the welding surface and improve the welding effect. By pulling the connecting rod 203, the connecting rod 203 is made to slide out of the adjusting rod 202, and the first grinding wheel 208 or the second grinding wheel 209 is separated from the double-layer transmission wheel 206. Then, the hollow support rod 204 is turned on the connecting rod 203 to swap the two ends of the hollow support rod 204 to adjust the shape of the grinding component.

The second grinding wheel 209 or the first grinding wheel 208 at the other end can be driven to rotate through a belt to grind the surface of the welding component. During this period, the supporting short rod 207 at the front end can be rotated as needed to adjust the angle of the first grinding wheel 208 or the second grinding wheel 209 to change the shape and range of grinding.

A pair of clamping brackets 304 are slidably installed in the through slot of the feeding rod 303. A compression spring is fixedly installed between the clamping bracket 304 and the feeding rod 303. A plurality of clamping wheels 306 are rotatably installed in the clamping bracket 304. The clamping wheels 306 are used to clamp welding rods. Gear patterns are fixedly installed on the clamping wheels 306. A transmission threaded rod 307 is rotatably installed in the clamping bracket 304.

A second driving motor 305 is fixedly installed at one end of the clamping bracket 304, and the second driving motor 305 is fixedly connected to the transmission threaded rod 307, and the welding rod is clamped by the clamping wheel 306. At the same time, the second driving motor 305 is started to drive the transmission threaded rod 307 to rotate, and the rotation of the transmission threaded rod 307 drives the clamping wheel 306 to rotate, driving the welding rod to slowly extend out to weld the components. At the same time, the rotation angle of the feeding rod 303 in the lower cover plate 301 is adjusted according to needs, and the distance between the top of the welding rod and the welding head 105 is changed to adjust the welding effect.

[0032] like Figures 1 to 10As shown, a reinforcement plate 104 is fixedly installed on the outside of the welding rod 102, a slide groove is provided on one side of the reinforcement plate 104, a positioning groove is provided in the slide groove of the reinforcement plate 104, a sliding plate 107 is slidably installed in the reinforcement plate 104, a positioning plate 108 is slidably installed in the sliding plate 107, a compression spring is fixedly installed between the positioning plate 108 and the sliding plate 107, a positioning groove is provided on the top of the positioning plate 108, and the positioning ruler on the top of the positioning plate 108 cooperates with the positioning groove in the slide groove of the reinforcement plate 104, a supporting short rod is provided on one side of the upper cover plate 201, and a support rod 4 is hinged between the sliding plate 107 and the supporting short rod on the outside of the upper cover plate 201, which is used to fix the angle between the upper cover plate 201 and the welding rod 102.

[0033] Working principle: When performing welding work, first flip the hollow support rod 204 according to the shape of the component surface, flip the required first grinding wheel 208 or second grinding wheel 209 to the front end, and rotate the supporting short rod 207 at the front end to adjust the angle of the first grinding wheel 208 or the second grinding wheel 209, then press the positioning plate 108 to separate the positioning teeth on the positioning plate 108 from the positioning groove in the slide groove of the reinforcement plate 104, then pull the upper cover plate 201 to rotate on the welding bracket 101, adjust the angle of the upper cover plate 201, and adjust the angle between the lower cover plate 301 and the welding bracket 101 at the same time, and support the equipment by contacting the support wheel at the front end of the telescopic rod 302 with the component, then start the first drive motor 205 to drive the first grinding wheel 208 or the second grinding wheel 209 to rotate, grind the surface of the component, and remove impurities on the surface of the component.

[0034] During welding, according to the welding method required, the electric welding head 105 is moved to slide on the front end of the welding rod 102 to expose or hide the gas welding head 106, thereby switching different welding modes.

[0035] During welding, the feeding rod 303 is rotated in the lower cover plate 301 according to the demand to control the distance between the top of the welding rod and the electric welding head 105 and adjust the welding effect.
