Description

Technical Field

[0001] The invention relates to the technical field of welding equipment manufacturing, in particular to a girth welder turnover tool for automobile parts processing. Background Art

[0002] Auto parts processing refers to the various units that constitute the overall auto parts processing and the products that serve the auto parts processing. As the foundation of the automobile industry, auto parts are the necessary factors to support the sustainable and healthy development of the automobile industry. A turning tool for processing automobile parts described in a patent application with publication number CN216464471U relates to the technical field of welding equipment manufacturing. The turning tool for processing automobile parts comprises: a processing table, a fixed plate is arranged above the processing table, and the turning tool is fixed on the surface of the fixed plate; a storage and protection component, including an elastic storage part and a protective traction part; the beneficial effect is: by setting the two sides of the storage plate as an open structure, it is convenient to store parts to be processed of different lengths and sizes. When the parts to be processed are placed, a layer of anti-scratch foam sheet is placed between adjacent parts to be processed to prevent the parts to be processed from scratching each other. The guide rod drives the limit plate to move outward, and the compressed storage spring pushes the limit plate and the protective plate to move inward to protect and clamp the parts to be processed to prevent the parts to be processed from shaking. The protective hook cooperates with the fixed ring to drive the protective rope to extend, and the protective rope protects the parts to be processed longitudinally to prevent the parts to be processed from falling.

[0003] Most automotive parts are hollow cylindrical parts. When circular seam welding is performed on cylindrical hollow parts, they are clamped by a clamping machine and then rotated. The circular seam welding can be completed by welding with a welding head. However, when clamping for circular welding, the clamping operation is slow and once the clamping is not concentric with the rotation, the welding head and the part surface are sometimes far away and sometimes close during rotation welding, which affects the welding accuracy.

[0007] Preferably, the inner wall of the lifting ring is slidably connected to the outer wall of the connecting column, the bottom of the lifting ring is fixedly connected to a spring, and one end of the spring is fixedly connected to the top of the driving motor group.

[0008] Preferably, the roller A is made of rubber, and the outer wall of the connecting column is slidably connected to the inner wall of the lifting ring through a sliding groove. The sliding groove allows the lifting ring to be lifted vertically on the outer wall of the connecting column and prevents the lifting ring from rotating relative to the connecting column.

[0009] Preferably, the top of the opening and closing rotating plate is fixedly connected with an arc plate A, the outer wall of the arc plate A is slidably connected with an arc sleeve, and the inner wall of the arc sleeve is slidably connected with an arc plate B.

[0013] The present invention provides a turning tool for a girth welder for automobile parts processing, which has the following beneficial effects: 1. The present invention sets a clamping mechanism, and the lifting angle of each opening and closing rotating plate is uniformly fixed. The three opening and closing rotating plates are pressed against the parts, so that the parts can be automatically clamped and the parts can be completely centered between the connecting column and the driving motor group. Therefore, when the driving motor group is rotated to perform circumferential welding, it can be ensured that the parts and the driving motor group rotate with the same center of the circle, thereby avoiding the problem that the distance between the welding head and the part surface is sometimes close and sometimes far during rotation due to the displacement of the center position of the part fixed on the driving motor group during rotation welding, resulting in uneven and non-uniform welds on the parts welded with circumferential welds.

[0014] 2. The present invention realizes automatic clamping and positioning of parts by setting a clamping mechanism and automatically pressing down and lifting the opening and closing rotating plate. The operation is convenient and fast, and the possibility of operating errors is avoided. In addition, the problem of obstruction during the circumferential seam welding of the outer wall can be effectively avoided by internal clamping.

[0015] 3. The present invention sets a clamping mechanism, which can fix the parts axially in rotation without limiting the flexibility of lifting and lowering, so that when the parts are pressed down and fixed therein, and after the circumferential seam welding is completed, they can be directly taken vertically, which is convenient and quick, and the work efficiency is improved. In addition, when the circumferential seam welding is performed, the parts are axially fixed, and the stability of the circumferential seam welding can also be maintained.

[0016] 4. The present invention sets a clamping mechanism so that roller B also has the elastic force of its built-in spring to maintain stable squeezing with the inner wall of the part, and then through the multi-point support of the upper and lower rollers B and roller A, it effectively prevents the shaking of the parts during rotation welding, further improves the stability of the parts under rapid fixation, and effectively reduces the use of materials and maximizes the utilization of the fixing effect through a multi-point fixing method.

[0017] 5. The present invention sets an identification mechanism, and the height of the lifting rod can be effectively observed through the annular scale groove on the outer wall of the lifting rod, and the specific diameter range of the part can be identified. Similarly, the less the lifting rod rises, the larger the diameter of the inner wall of the circular part. After the part is fixed, the specific data of the part can be quickly determined by observing the lifting and lowering of the lifting rod, thereby facilitating the adjustment of the subsequent circumferential seam welding.

DETAILED DESCRIPTION

[0020] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a turning tool for a girth welder for automobile parts processing, comprising a welding table 1, a welding machine 2 is fixedly connected to the top of the welding table 1, a welding head 5 is arranged outside the welding machine 2, and a clamping mechanism 3 is arranged below the welding machine 2; The clamping mechanism 3 comprises: The driving motor group 301 has a bottom fixedly connected to the bottom of the welding machine 2, a connecting column 302 fixedly connected to the top of the driving motor group 301, and a rotating shaft A303 is rotatably connected to the outer wall of the connecting column 302. The driving motor group 301 is used to drive the parts to rotate; An opening and closing rotating plate 304, one end of which is fixedly connected to the outer wall of the rotating shaft A303, a roller A305 is rotatably connected to the outer wall of the opening and closing rotating plate 304, a hinge block A306 is fixedly connected to the bottom of the opening and closing rotating plate 304, a rectangular groove is provided on the inner wall of the opening and closing rotating plate 304, and the opening and closing rotating plate 304 is used to be squeezed by parts to drive the rotating shaft A303 to rotate and descend together.

[0021] When in use, the hollow circular sleeve to be welded is placed on the driving motor group 301, and then the driving motor group 301 is started to drive the circular hollow part to rotate, and at the same time, the welding machine 2 is started to control the welding head 5 to move to the designated welding point, and the welding of the welding head 5 is started. As the driving motor group 301 drives the parts to rotate, the circumferential seam welding work is realized.

[0022] Example 2: Please refer to Figure 1-11 On the basis of the first embodiment, the present invention provides a technical solution: the inner wall of the hinge block A306 is hinged with a hinge rod 307, one end of the hinge rod 307 is hinged with a hinge block B308, and the outer wall of the hinge block B308 is fixedly connected with a lifting ring 309.

[0023] The inner wall of the lifting ring 309 is slidably connected to the outer wall of the connecting column 302 . A spring 311 is fixedly connected to the bottom of the lifting ring 309 . One end of the spring 311 is fixedly connected to the top of the driving motor group 301 .

[0024] Roller A305 is made of rubber material, and the outer wall of the connecting column 302 is slidably connected to the inner wall of the lifting ring 309 through a sliding groove. The sliding groove allows the lifting ring 309 to rise and fall vertically on the outer wall of the connecting column 302 and prevents the lifting ring 309 from rotating relative to the connecting column 302.

[0025] The top of the opening and closing rotating plate 304 is fixedly connected with an arc plate A312, the outer wall of the arc plate A312 is slidably connected with an arc sleeve 313, and the inner wall of the arc sleeve 313 is slidably connected with an arc plate B314.

[0026] One end of the arc plate B314 is rotatably connected to a rotating shaft B315, and an outer wall of the rotating shaft B315 is fixedly connected to a roller B316, which is made of rubber.

[0027] When the circular hollow sleeve-shaped component is placed on the driving motor group 301, the bottom of the component will first contact the top of the opening and closing rotating plate 304, and as it continues to be pressed down, it will press against the opening and closing rotating plate 304, and continue to press down, so that when the component pushes the opening and closing rotating plate 304, the opening and closing rotating plate 304 will descend through the rotation of the rotating shaft A303 in the connecting column 302, and when the opening and closing rotating plate 304 descends, the hinge block A306 pushes the hinge rod 307, the hinge rod 307 pushes the hinge block B308, and the hinge block B308 pushes the lifting ring 309 to slide and descend on the outer wall of the connecting column 302, and the connecting column 302 plays a role in the lifting ring The lifting ring 309 has a vertical lifting limit function, and when the lifting ring 309 descends, it squeezes the spring 311 at the bottom and deforms it, and then slides down on the outer wall of the connecting column 302, so that the elastic force of the deformation of the spring 311 will make the part press up and down on the three opening and closing rotating plates 304 to provide greater resistance, so that after the part is pressed to overcome the resistance of the three opening and closing rotating plates 304 hingedly descending, one end of the opening and closing rotating plate 304 will enter the inner wall of the part until the part is completely pushed onto the driving motor group 301, at this time, one end of the opening and closing rotating plate 304 is against the inner wall of the part, and the lifting ring 309 is always subject to the rebound and upward force of the spring 311, Then, the force of pushing the lifting ring 309 upward is pushed to the opening and closing rotating plate 304 through the hinge block B308, the hinge rod 307, and the hinge block A306, so that the opening and closing rotating plate 304 always maintains the upward lifting force, and the hinged rotation of the opening and closing rotating plate 304 is carried out with the rotation axis A303 as the center. Therefore, when the opening and closing rotating plate 304 is subjected to the upward lifting force, an outward squeezing force is applied to the inner wall of the part, so that the three opening and closing rotating plates 304 tightly press the three contact points of the inner wall of the part, so that the part is automatically clamped and tightened after being inserted into the three opening and closing rotating plates 304, and the three hinge rods 307 are connected to the same lifting ring 309 through the hinge block B308. The three opening and closing rotating plates 304 are connected, so the lifting angle of each opening and closing rotating plate 304 is uniformly fixed. The three opening and closing rotating plates 304 are pressed against the parts, so that the parts can be automatically clamped and the parts are completely centered between the connecting column 302 and the driving motor group 301. Therefore, when the driving motor group 301 is rotated to perform circumferential welding, it can be ensured that the parts and the driving motor group 301 rotate with the same center of the circle, so as to avoid the problem that the distance between the welding head 5 and the surface of the parts is sometimes close and sometimes far when rotating, because the center position of the parts is fixed on the driving motor group 301 during rotation welding, and the problem of uneven and non-uniform welds on the parts of the circumferential welding is avoided; By directly pressing down on the parts, the parts can be quickly fixed on one end of the three opening and closing rotating plates 304, and the inner wall of the parts can be firmly pressed by the extrusion force of the opening and closing rotating plates 304, and the roller A305 rolling on one end of the opening and closing rotating plates 304 can contact the inner wall of the parts. Since the roller A305 is made of rubber and can roll on one end of the opening and closing rotating plates 304, the roller A305 can roll when the parts are pressed down, so that the positive vertical downward pressure is fast, and after the parts are firmly pressed by the opening and closing rotating plates 304 and the roller A305, the roller A305 can be pressed down by the roller A305. 5 cannot rotate horizontally, and the friction force is used to prevent the part from rotating axially on the outer wall of the roller A305. During the circumferential seam welding, since the driving motor group 301 needs to drive the part to rotate, and the part does not need to be lifted, and will not be subject to the force of lifting up and down, this method can fix the part in axial rotation, but does not limit its lifting flexibility, so that when the part is pressed down and fixed therein, and after the circumferential seam welding is completed, it is more convenient and faster to directly take it vertically, and the work efficiency is improved. During the circumferential seam welding, the part is fixed axially, and the stability of the circumferential seam welding can also be maintained; When the opening and closing rotating plate 304 is pressed down by the bottom of the part, the arc plate A312 on the outer wall of the opening and closing rotating plate 304 will be rotated together. When the opening and closing rotating plate 304 rotates downward, the arc plate A312 also rotates downward synchronously, thereby rotating the arc plate A312, the arc sleeve 313, and the arc plate B314 from the original raised shape to a horizontal shape. Then, the arc plate B314 and the roller B316 that originally could not contact the inner wall of the part will begin to contact and resist the inner wall of the part. As the opening and closing rotating plate 304 continues to be pressed down more, the squeezing force between the roller B316 and the inner wall of the part is also increased, and the part is quickly lifted and lowered by the rolling of the roller B316 in the same way as the roller A305. , and one end of the arc plate B314 is connected to one end of the arc plate A312 with a built-in spring, and the built-in spring is located inside the arc sleeve 313. After the roller B316 presses against the inner wall of the part, the reaction force pushes the arc plate B314 to slide on the inner wall of the arc sleeve 313, which squeezes the built-in spring and causes it to deform. Therefore, the roller B316 also has the elastic force of its built-in spring to keep stable and squeeze the inner wall of the part. Then, through the multi-point support of the upper and lower rollers B316 and the roller A305, the shaking of the parts during rotation welding is effectively prevented, and the stability of the parts under rapid fixation is further improved. Through the multi-point fixing method, the use of materials can be effectively reduced and the utilization of the fixing effect can be maximized.

[0028] Example 3: Please refer to Figure 1-12On the basis of the first and second embodiments, the present invention provides a technical solution: an identification mechanism 4 is arranged outside the connecting column 302, and the identification mechanism 4 includes a circular frame 401, the top of the circular frame 401 is fixedly connected to the bottom of the lifting ring 309, the inner wall of the circular frame 401 does not contact the outer wall of the connecting column 302, the outer wall of the circular frame 401 is slidably connected to the inner wall of the fixing sleeve 402, and the bottom of the circular frame 401 and the inner wall of the fixing sleeve 402 form a closed space.

[0029] The inner wall of the fixed sleeve 402 is fixedly connected with a connecting pipe 403, the inner wall of the fixed sleeve 402 is communicated with the inner wall of the connecting pipe 403, the other end of the connecting pipe 403 is fixedly connected with the outer wall of the connecting column 302, the interior of the connecting pipe 403 is communicated with the interior of the connecting column 302, the inner wall of the connecting column 302 is slidably connected with a lifting rod 404, and the outer wall of the lifting rod 404 is provided with an annular scale groove 405.

[0030] When the lifting ring 309 descends, the circular frame 401 will be driven to descend synchronously. When the circular frame 401 descends, the bottom will slide and descend in the inner wall of the fixed sleeve 402, and squeeze the hydraulic oil in the enclosed space of the inner wall of the fixed sleeve 402 into the connecting pipe 403, and enter the inner wall of the connecting column 302 through the connecting pipe 403. The hydraulic oil in the inner wall space of the connecting column 302 increases, and the lifting rod 404 above is pushed up, and the lifting rod 404 is pushed out from the connecting column 302. The circular hollow parts with different diameters descend to push the opening and closing rotating plate 304 to rotate at different angles, and the different rotation angles of the opening and closing rotating plate 304 will push the lifting ring through the hinge block A306, the hinge rod 307, and the hinge block B308. 309 descends to different degrees, and the different degrees of descent of the lifting ring 309 will eventually cause the lifting rod 404 to rise to different degrees. Therefore, when the part with a smaller diameter presses down the opening and closing rotating plate 304 and clamps it through the opening and closing rotating plate 304, the lifting rod 404 rises higher from the connecting column 302. The height of the lifting rod 404 can be effectively observed through the annular scale groove 405 on the outer wall of the lifting rod 404, and the specific diameter range of the part can be identified. Similarly, the less the lifting rod 404 rises, the larger the diameter of the inner wall of the circular part. After the part is fixed, the specific data of the part can be quickly determined by observing the lifting and lowering of the lifting rod 404, thereby facilitating the subsequent adjustment of the annular seam welding.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
