[0003] In the early stage of surfacing the end face of the roller sleeve, manual hand-held welding was adopted, and the yield rate was 80%. The main reason was that the hand-held welding could not control the moving speed, the molten pool temperature was unstable, the welding slag failed to float out of the molten pool in time and agglomerated, and the cooled molten pool was slag-included, resulting in unqualified welding quality, and the weld nodule was large, the surface was uneven, and slag was included inside the surfacing area. When turning on the lathe, the tool needs to be repeatedly sharpened to turn the surfacing end face on one side. After turning, it returns to the surfacing area, re-surfacing, and turning again, which leads to low production efficiency and the inability to complete the surfacing task of the roller sleeve end face on time and as needed. Therefore, in view of the above problems, a welding machine for surfacing the end face of the roller sleeve is proposed. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, the present invention provides a welding machine for roller sleeve end face surfacing, comprising a base 1, and also comprising: A fixing mechanism 3, wherein the fixing mechanism 3 is arranged on the base 1 through the transmission mechanism 2; A chip removal mechanism 4, which is arranged on the transmission mechanism 2; The transmission mechanism 2 includes a bottom plate 201, a bottom outer wall of the bottom plate 201 is bearing-connected to a transmission shaft 203 via a first bearing 204, and an outer wall of the bottom plate 201 is bearing-connected to a second bevel gear 206 via a second bearing 207; The fixing mechanism 3 includes a placing table 301, the inner wall of the placing table 301 is rotatably connected to a driving disk 304, the outer wall of the driving disk 304 is rotatably connected to a rotating disk 306, the top outer wall of the placing table 301 is slidably connected to a clamping plate 312, and the top outer wall of the placing table 301 contacts the roller sleeve body 5; The chip removal mechanism 4 includes a fixed rod 401 , and an outer wall of the fixed rod 401 is elastically connected to a knocking plate 403 via a spiral spring 404 .

[0020] The above scheme is adopted: the base 1 is the part of the open arc welding machine for roller sleeve end face surfacing placed on the ground, and the welding machine body is arranged above the base 1, which is the existing technology; the roller sleeve can be placed vertically and surfacing can be performed through the transmission mechanism 2; the bottom plate 201 can be welded on the base 1, and the gear 202 can be connected to the existing drive module in the welding machine, such as a motor, for transmission; the first bearing 204 is provided with two groups, the outer ring of which is fixedly connected to the outer wall of the bottom end of the bottom plate 201, and the inner ring is fixedly connected to the outer wall of the transmission shaft 203, and the outer ring of the second bearing 207 is also fixed on the bottom plate 201, and the inner ring is connected to the second cone The outer wall of the gear 206 is fixed, and a through groove is opened on the bottom plate 201 at the position of the second bearing 207 and the second bevel gear 206 for installing the second bearing 207; the first bearing 204 and the second bearing 207 are both existing technologies, and the driving module can drive the gear 202 and the transmission shaft 203 to rotate synchronously, and drive the first bevel gear 205 to rotate, so that the second bevel gear 206 meshing with it rotates synchronously, and then when the bottom plate 201 is fixed, it drives the second bearing 207 and the fixing mechanism 3 to rotate synchronously, so that the roller sleeve body 5 fixed on the placement table 301 can be rotated to weld the surface.

[0021] like Figures 2 to 3As shown, the bottom plate 201 is fixedly connected to the base 1, the outer wall of one end of the transmission shaft 203 is fixedly connected to the gear 202, and the outer wall of the other end of the transmission shaft 203 is fixedly connected to the first bevel gear 205; the second bevel gear 206 is meshed with the first bevel gear 205, and the second bevel gear 206 is rotatably connected to the outer wall of the bottom end of the bottom plate 201 The above scheme is adopted: by improving the transmission mode of the existing open arc welding machine, the transmission mode of the transmission mechanism 2 has high transmission efficiency, is suitable for harsh environments such as high temperature, humidity, dust, pollution, etc., and will not have elastic sliding and slipping phenomena. The transmission ratio is accurate and can transmit greater power. At the same time, the overall transmission mechanism 2 is light in weight, long in service life, and low in cost. The efficiency of surfacing the end face of the roller sleeve is higher than that of manual surfacing, which greatly improves production efficiency.

[0022] like Figures 4 to 5 As shown, the placement table 301 is rotatably connected to the top outer wall of the base plate 201, the inner wall of the placement table 301 is rotatably connected to the worm gear 302, the inner wall of the placement table 301 is rotatably connected to the worm 303, the outer wall of the active disk 304 is provided with a slot 305, the inner wall of the turntable 306 is elastically connected to the block 309 through a connecting spring 308, the outer wall of the turntable 306 is provided with an inclined slot 307, the top outer wall of the placement table 301 is provided with a guide slot 310, the inner wall of the guide slot 310 is slidably connected to a slide rod 311, and the outer wall of the slide rod 311 is fixedly connected to a clamping plate 312.

[0023] By adopting the above scheme: the fixing mechanism 3 can adjust the position of the three groups of clamps 312, so that it can clamp and fix roller sleeves of different diameters, with higher adaptability and more convenient operation; the worm wheel 302 and the worm 303 are both existing technologies, and can only drive the worm wheel 302 to rotate synchronously when the worm 303 rotates, while the worm wheel 302 cannot rotate alone; the sliding rod 311 can always slide in the inner walls of the guide groove 310 and the inclined groove 307, thereby driving the clamps 312 to move and adjust their positions; the turntable 306 and the active disk 304 can be fixed by clamping the clamping block 309 with the clamping groove 305.

[0024] like Figure 5 As shown, the worm wheel 302 is meshed with the worm 303, one end of the connecting spring 308 is fixedly connected to the outer wall of the block 309, and the other end of the connecting spring 308 is fixedly connected to the inner wall of the rotating disk 306; the block 309 is slidably connected to the inner wall of the rotating disk 306, the block 309 is engaged with the slot 305, the slide bar 311 is in contact with the inner wall of the inclined slot 307, and the worm wheel 302 is fixedly connected to the outer wall of the bottom end of the active disk 304.

[0025] The above scheme is adopted: under normal conditions, the block 309 is engaged with a group of slots 305 due to the elastic force of the connecting spring 308. When the block 309 is pulled, the limit between the turntable 306 and the active disk 304 can be released. At this time, the turntable 306 is rotated. Under the action of the worm gear 302 and the worm 303, the active disk 304 will not rotate. When the turntable 306 rotates, the inclined groove 307 will squeeze the slide bar 311, driving it to move to the middle or outside at the same time under the guidance of the guide groove 310, so as to adjust the distance between the three groups of clamping plates 312; there are multiple groups of clamping grooves 305, and the turntable 306 can be rotated to the position where the clamping plate 312 is close to the roller sleeve body 5, and the turntable 306 and the active disk 304 are fixed by engaging the block 309 with the slot 305.

[0026] like Figure 5 As shown, one end of the worm 303 passes through the outer wall of the placement table 301. After the turntable 306 is rotated to adjust the position of the clamping plate 312, the worm 303 can be rotated to drive the worm wheel 302, the active disk 304 and the turntable 306 to rotate synchronously, and the slide bar 311 is squeezed through the inclined groove 307 to move along the inner wall of the guide groove 310, so as to adjust the position of the three groups of clamping plates 312 more accurately, so that the clamping plates 312 can be firmly attached to the roller sleeve body 5 to clamp and fix it; the overall adjustment operation is relatively convenient, and there is no need to rotate the threaded rod for a long time to adjust and clamp the position of the clamping claws, which saves time and effort.

[0027] like Figure 6 As shown, the outer wall of the bottom end of the knocking plate 403 is fixedly connected to a rotating ring 402, the outer wall of the rotating ring 402 is fixedly connected to a stopper 406, and the outer wall of the placement table 301 is fixedly connected to a protrusion 405; one end of the spiral spring 404 is fixedly connected to the outer wall of the knocking plate 403, and the other end of the spiral spring 404 is fixedly connected to the outer wall of the fixed rod 401.

[0028] The above scheme is adopted: when the driving mechanism inside the welding machine drives the fixing mechanism 3 to rotate as a whole through the transmission mechanism 2, the protrusion 405 will rotate with the placement table 301, and the protrusion 405 will squeeze the arc surface of the stopper 406, so that it and the rotating ring 402 drive the knocking plate 403 to flip horizontally, and the knocking plate 403 and the rotating ring 402 are connected and fixed by a connecting rod. When the knocking plate 403 rotates, the spiral spring 404 is compressed; when the fixing mechanism 3 rotates until the protrusion 405 is out of contact with the stopper 406, the elastic force of the spiral spring 404 will drive the knocking plate 403, the rotating ring 402, and the stopper 406 to rotate in the opposite direction and reset. At this time, the knocking plate 403 will contact the surface of the roller sleeve body 5 and strike it, so that the waste chips left on the surface of the roller sleeve body 5 due to welding will fall off instead of adhering to the surface of the roller sleeve body 5.

[0029] like Figure 6As shown, the fixed rod 401 is fixedly connected to the top outer wall of the bottom plate 201, and the rotating ring 402 is rotatably connected to the outer wall of the fixed rod 401; the protrusion 405 contacts the outer wall of the stopper 406, and the knocking plate 403 is rotatably connected to the outer wall of the fixed rod 401.

[0030] By adopting the above scheme: during the welding process, the fixing mechanism 3 will drive the roller sleeve body 5 to rotate continuously, so that the knocking plate 403 in the chip removal mechanism 4 will continuously knock the roller sleeve body 5, thereby ensuring that no excessive chips will remain on the surface of the roller sleeve body 5, avoiding the problem of chips affecting the welding effect.

[0031] The working principle and use process of the present invention: The operator can weld and fix the bottom plate 201 on the base 1, connect the gear 202 with the motor or other drive module in the welding machine, and complete the installation of the transmission mechanism 2; then place the roller sleeve body 5 on the top outer wall of the placement table 301, pull the clamping block 309, release the limit between the turntable 306 and the active disk 304, rotate the turntable 306, and the inclined groove 307 squeezes the slide bar 311. Under the guidance of the guide groove 310, the slide bar 311 drives the three groups of clamping plates 312 to move to the middle or outside at the same time, and adjusts the clamping plate 312 to a position close to the roller sleeve body 5; after the adjustment is completed, release the clamping block 309, and under the elastic force of the connecting spring 308, the clamping block 309 is clamped with another group of clamping grooves 305, fix the turntable 306 and the active disk 304, and complete the preliminary adjustment of the position of the clamping plate 312.

[0032] Then the worm 303 is rotated, and the worm 303 drives the worm wheel 302 to rotate, so that the active disk 304 and the rotating disk 306 rotate synchronously. During the rotation, the inclined groove 307 squeezes the sliding rod 311 again, so that it moves along the inner wall of the guide groove 310, and the positions of the three groups of clamping plates 312 are adjusted more accurately until the clamping plates 312 are firmly attached to the roller sleeve body 5, thereby completing the clamping and fixing of the roller sleeve body 5.

[0033] After the roller sleeve body 5 is fixed, the driving module of the welding machine can be started, and the driving module drives the gear 202 to rotate, and the gear 202 drives the transmission shaft 203 to rotate synchronously, and the first bevel gear 205 at one end of the transmission shaft 203 rotates accordingly, and the second bevel gear 206 meshing with the first bevel gear 205 also rotates synchronously. When the bottom plate 201 is fixed, the rotation of the second bevel gear 206 drives the second bearing 207 to rotate synchronously with the fixing mechanism 3, so that the roller sleeve body 5 fixed on the placement table 301 rotates, and the welding machine can perform surfacing operations on the surface of the rotating roller sleeve body 5.

[0034] During the welding process, a large amount of waste chips will be generated, some of which will fall to the ground, and some of which will remain inside the weld or adhere to the surface of the roller sleeve body 5; when the driving mechanism inside the welding machine drives the fixing mechanism 3 to rotate as a whole through the transmission mechanism 2, the protrusion 405 on the outer wall of the placement table 301 will rotate together with the placement table 301, squeezing the stopper 406, and the stopper 406 and the rotating ring 402 drive the knocking plate 403 to rotate horizontally, and the volute spring 404 is compressed when the knocking plate 403 rotates; when the fixing mechanism 3 rotates until the protrusion 405 is out of contact with the stopper 406, under the action of the elastic force of the volute spring 404, the knocking plate 403 strikes the roller sleeve body 5, so that the waste chips remaining on the surface of the roller sleeve body 5 fall off, ensuring that too much waste chips will not remain on the surface of the roller sleeve body 5, and avoiding the waste chips from affecting the welding effect.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
