A rotary tool for circumferential seam welding machine used in automobile parts processing

Abstract

The present invention discloses a turnover tooling for circumferential seam welding machine in the processing of automobile parts, which relates to the technical field of welding equipment manufacturing. It includes a welding table, a welding machine is fixedly connected to the top of the welding table, a welding head is arranged outside the welding machine, and a clamping mechanism is arranged below the welding machine; by setting the clamping mechanism, the lifting angle of each opening and rotating plate is uniformly fixed. When the three opening and rotating plates resist the parts, automatic clamping of the parts can be achieved and the parts can be completely centered on the connecting column and the driving motor group. Thus, when the driving motor group rotates for circumferential seam welding subsequently, it can be ensured that the parts and the driving motor group rotate with the same center of circle. To avoid the problem that when the circumferential seam is rotationally welded, the distance between the welding head and the surface of the parts is sometimes near and sometimes far during rotation due to the offset of the center position of the parts fixed on the driving motor group, resulting in uneven and inconsistent weld seams on the parts of the circumferential seam welding.

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.

[0003] 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.

[0004] 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. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a turning tool for a girth welder for processing automobile parts, which achieves the purpose of solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A girth welder flip tool for automobile parts processing, comprising a welding table, a welding machine is fixedly connected to the top of the welding table, a welding head is arranged outside the welding machine, and a clamping mechanism is arranged below the welding machine;

[0007] The clamping mechanism comprises:

[0008] A driving motor set, the bottom of the driving motor set is fixedly connected to the lower part of the welding machine, the top of the driving motor set is fixedly connected with a connecting column, the outer wall of the connecting column is rotatably connected with a rotating shaft A, and the driving motor set is used to drive the parts to rotate.

[0009] An opening and closing rotating plate, one end of the opening and closing rotating plate is fixedly connected to the outer wall of the rotating shaft A, the outer wall of the opening and closing rotating plate is rotatably connected with a roller A, the bottom of the opening and closing rotating plate is fixedly connected with a hinge block A, and a rectangular groove is opened on the inner wall of the opening and closing rotating plate. The opening and closing rotating plate is used to be squeezed by the parts to drive the rotating shaft A to rotate and descend together.

[0010] Preferably, a hinge rod is hinged inside the hinge block A, one end of the hinge rod is hinged with a hinge block B, and a lifting ring is fixedly connected to the outer wall of the hinge block B.

[0011] Preferably, the inner wall of the lifting ring is slidably connected to the outer wall of the connecting column, a spring is fixedly connected to the bottom of the lifting ring, and one end of the spring is fixedly connected to the top of the driving motor set.

[0012] 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 chute. The chute is used to give the lifting ring a vertical lift on the outer wall of the connecting column and prevent the lifting ring from rotating relative to the connecting column.

[0013] Preferably, an arc-shaped plate A is fixedly connected to the top of the opening and closing rotating plate, an arc-shaped sleeve is slidably connected to the outer wall of the arc-shaped plate A, and an arc-shaped plate B is slidably connected to the inner wall of the arc-shaped sleeve.

[0014] Preferably, one end of the arc-shaped plate B is rotatably connected to a rotating shaft B, a roller B is fixedly connected to the outer wall of the rotating shaft B, and the roller B is made of rubber.

[0015] Preferably, an identification mechanism is arranged outside the connecting column. The identification mechanism includes a circular frame. The top of the circular frame is fixedly connected to the bottom of the lifting ring. The inner wall of the circular frame does not contact the outer wall of the connecting column. The outer wall of the circular frame is slidably connected to the inner wall of a fixed sleeve, and a sealed space is formed between the bottom of the circular frame and the inner wall of the fixed sleeve.

[0016] Preferably, a connecting pipe is fixedly connected to the inner wall of the fixed sleeve. The inner wall of the fixed sleeve is communicated with the inner wall of the connecting pipe. The other end of the connecting pipe is fixedly connected to the outer wall of the connecting column. The inside of the connecting pipe is communicated with the inside of the connecting column. A lifting rod is slidably connected to the inner wall of the connecting column, and an annular scale groove is opened on the outer wall of the lifting rod.

[0017] The present invention provides a turnover tooling for a circumferential seam welding machine in the processing of automobile parts. It has the following beneficial effects:

[0018] 1. The present invention realizes the automatic clamping of parts and completely centers the parts on the connecting column and the drive motor set by setting a clamping mechanism. The lifting angle of each opening and closing rotating plate is uniformly fixed, and the three opening and closing rotating plates abut against the parts. Thus, when the drive motor set rotates for circumferential welding subsequently, it can ensure that the parts and the drive motor set rotate around the same center. This can avoid the problem that during the rotary welding of the circumferential seam, the distance between the welding head and the surface of the parts is sometimes near and sometimes far due to the offset of the center position of the parts fixed on the drive motor set, resulting in uneven and inconsistent weld seams of the parts in the circumferential seam welding.

[0019] 2. The present invention realizes the automatic clamping and positioning of parts through the automatic pressing and lifting of the opening and closing rotating plates by setting a clamping mechanism. The operation is convenient and fast, avoiding the possibility of operation errors. Moreover, through the internal clamping method, it can effectively avoid the problem of being blocked during the circumferential seam welding on the outer wall.

[0020] 3. The present invention realizes the fixation of the axial rotation of parts but does not limit the flexibility of its lifting by setting a clamping mechanism. Thus, when pressing and fixing the parts therein and directly vertically taking them after the circumferential seam welding is completed, it is relatively convenient and fast, improving the work efficiency. And during the circumferential seam welding, the axial fixation of the parts can also maintain the stability of the circumferential seam welding.

[0021] 4. The present invention realizes that the roller B also has the elastic force of its built-in spring to stably press against the inner wall of the parts through setting a clamping mechanism. Then, through the multi-point support of the upper and lower roller B and the roller A, it effectively prevents the shaking of the parts during the rotary welding, further improving the stability of the parts under rapid fixation. Through the multi-point fixation method, it effectively reduces the material usage and maximizes the fixation effect.

[0022] 5. The present invention can effectively observe its height and identify the specific diameter range of the parts through the annular scale groove on the outer wall of the lifting rod by setting an identification mechanism. Similarly, the less the lifting rod rises, the larger the inner diameter of the circular parts. After the parts are fixed, it is possible to quickly judge the specific data of the parts by observing the lifting and lowering of the lifting rod, thus facilitating the subsequent adjustment of the circumferential seam welding.

Specific embodiments

[0036] Example 1: Please refer to Figures 1-4 , the present invention provides a technical solution: A circumferential seam welding flipping tool for automobile part processing, including 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;

[0037] The clamping mechanism 3 includes:

[0038] The drive motor set 301 is fixedly connected to the bottom of the welding machine 2. A connecting column 302 is fixedly connected to the top of the drive motor set 301. A rotating shaft A 303 is rotatably connected to the outer wall of the connecting column 302. The drive motor set 301 is used to drive the components to rotate.

[0039] The opening and closing rotating plate 304 has one end fixedly connected to the outer wall of the rotating shaft A 303. A roller A 305 is rotatably connected to the outer wall of the opening and closing rotating plate 304. A hinge block A 306 is fixedly connected to the bottom of the opening and closing rotating plate 304. A rectangular groove is provided in the inner wall of the opening and closing rotating plate 304. The opening and closing rotating plate 304 is used to be squeezed by the parts to drive the rotating shaft A 303 to rotate and descend together.

[0040] During use, the hollow circular sleeve to be welded is placed on the drive motor set 301. Then, the drive motor set 301 is started to drive the circular hollow part to rotate. At the same time, the welding machine 2 is started to control the welding head 5 to move to the specified welding position, and the welding of the welding head 5 is started. As the drive motor set 301 drives the components to rotate, the circumferential seam welding work is realized.

[0041] Embodiment 2: Please refer to Figures 1-11 , based on Embodiment 1, the present invention provides a technical solution: A hinge rod 307 is hinged to the inner wall of the hinge block A 306. One end of the hinge rod 307 is hinged to a hinge block B 308. A lifting ring 309 is fixedly connected to the outer wall of the hinge block B 308.

[0042] 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 drive motor set 301.

[0043] The roller A 305 is made of rubber. The outer wall of the connecting column 302 is slidably connected to the inner wall of the lifting ring 309 through a chute. This chute serves to enable the lifting ring 309 to vertically lift on the outer wall of the connecting column 302 and prevent the lifting ring 309 from rotating relative to the connecting column 302.

[0044] An arc-shaped plate A 312 is fixedly connected to the top of the opening and closing rotating plate 304. An arc-shaped sleeve 313 is slidably connected to the outer wall of the arc-shaped plate A 312. An arc-shaped plate B 314 is slidably connected to the inner wall of the arc-shaped sleeve 313.

[0045] One end of the arc-shaped plate B 314 is rotatably connected to a rotating shaft B 315. A roller B 316 is fixedly connected to the outer wall of the rotating shaft B 315. The roller B 316 is made of rubber.

[0046] When the circular hollow sleeve-shaped component is placed on the drive motor set 301, the bottom of the component will first contact the top of the opening and closing rotating plate 304. And as it is continuously pressed down and placed, it will press against the opening and closing rotating plate 304. And when continuously pressed down, 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, it will push the hinge rod 307 through the hinge block A306. The hinge rod 307 will push the hinge block B308, and the hinge block B308 will push the lifting ring 309 to slide down on the outer wall of the connecting column 302. The connecting column 302 plays a role in vertically limiting the lifting of the lifting ring 309. And when the lifting ring 309 descends, it will squeeze the spring 311 at the bottom and cause it to deform. Then it will slide down on the outer wall of the connecting column 302. Thus, the elastic force of the deformed spring 311 will provide a greater resistance when the component is pressed down on the three opening and closing rotating plates 304. Thus, after pressing the component to overcome the resistance of the three opening and closing rotating plates 304 to hinge and descend, one end of the opening and closing rotating plate 304 will enter the inner wall of the component until the component is completely pushed onto the drive motor set 301. At this time, one end of the opening and closing rotating plate 304 will press against the inner wall of the component. And because the lifting ring 309 is always subjected to the upward pushing force of the spring 311's rebound, the upward pushing force of the lifting ring 309 will be 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 also always maintains an upward lifting force. And the hinge rotation of the opening and closing rotating plate 304 is centered on the rotating shaft A303. So when the opening and closing rotating plate 304 is subjected to the upward lifting force, it will apply an outward extrusion force to the inner wall of the component. Thus, the three opening and closing rotating plates 304 will tightly press against the three contact points on the inner wall of the component, so that the component is automatically clamped and fastened after being sleeved outside the three opening and closing rotating plates 304. And the three hinge rods 307 are all connected to the same lifting ring 309 through the hinge block B308. So the lifting angle of each opening and closing rotating plate 304 is uniformly fixed. When the three opening and closing rotating plates 304 press against the component, the automatic clamping of the component can be realized and the component can be completely centered between the connecting column 302 and the drive motor set 301. Thus, when the subsequent drive motor set 301 rotates for circumferential welding, it can be ensured that the component and the drive motor set 301 rotate with the same center. To avoid the problem that when the circumferential seam is rotationally welded, because the center position of the component fixed on the drive motor set 301 is offset, the distance between the welding head 5 and the surface of the component is sometimes near and sometimes far during rotation, resulting in the problem of uneven and inconsistent weld seams of the circumferentially welded component;

[0047] 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;

[0048] 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.

[0049] Example 3: Please refer to Figures 1-12, based on the first and second embodiments, the present invention provides a technical solution: an identification mechanism 4 is arranged outside the connecting column 302. 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 fixed sleeve 402. A sealed space is formed between the bottom of the circular frame 401 and the inner wall of the fixed sleeve 402.

[0050] A connecting pipe 403 is fixedly connected to the inner wall of the fixed sleeve 402. 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 to the outer wall of the connecting column 302. The inside of the connecting pipe 403 is communicated with the inside of the connecting column 302. A lifting rod 404 is slidably connected to the inner wall of the connecting column 302. An annular scale groove 405 is formed on the outer wall of the lifting rod 404.

[0051] When the lifting ring 309 descends, it will synchronously drive the circular frame 401 to descend. When the circular frame 401 descends, its bottom will slide down in the inner wall of the fixed sleeve 402, and the hydraulic oil in the sealed space on the inner wall of the fixed sleeve 402 will be squeezed into the connecting pipe 403, and then enter the inner wall of the connecting column 302 through the connecting pipe 403. As the hydraulic oil in the inner wall space of the connecting column 302 increases, it will push the upper lifting rod 404 upwards, and the lifting rod 404 will be pushed out of the connecting column 302. Different-diameter circular hollow parts will push the opening and closing rotating plate 304 to rotate by different angles when they descend. Different rotation angles of the opening and closing rotating plate 304 will, through the hinge block A 306, the hinge rod 307, and the hinge block B 308, push the lifting ring 309 to descend to different degrees. Different degrees of descent of the lifting ring 309 will ultimately cause the lifting rod 404 to rise to different degrees. Thus, when a part with a smaller diameter presses down on the opening and closing rotating plate 304 and is clamped by the opening and closing rotating plate 304, the height of the lifting rod 404 rising from the connecting column 302 will be higher. The height 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 inner diameter of the circular part will be. After the part is fixed, by observing the lifting and lowering situation of the lifting rod 404, the specific data of the part can be quickly judged, which is convenient for subsequent adjustment of circumferential seam welding. The above is only a 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 and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
