Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a high-efficiency metal filler welding device. Background Art

[0002] Inclined tube sedimentation is a solid-liquid separation technology that uses inclined tubes as sedimentation media. Compared with traditional sedimentation tanks, inclined tube sedimentation tanks significantly increase the sedimentation area, improve sedimentation efficiency, and reduce the space and time required for sedimentation by arranging a large number of inclined tubular elements (inclined tubes). Its working principle is to use gravity to slowly let the suspended matter fall along the tube wall in the inclined tube, thereby achieving solid-liquid separation. The inclined angle design of the inclined tube can effectively guide the sedimentation particles and reduce mutual interference and resuspension between particles, ultimately improving the sedimentation effect. For example, in water purification and sewage treatment, inclined tube packings made of hard PVC and stainless steel are usually used. Stainless steel inclined tube packing has strong aging resistance under high water temperature conditions.

[0042] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0044] according to Figure 1-Figure 11 ,like Figure 1 and Figure 2 In the embodiment of the present invention, an efficient metal filler welding device includes a welding table 1, a material rack 2 fixedly mounted on the welding table 1 for placing fillers, and a feed rack 3 arranged on the periphery of the material rack 2 for conveying fillers. The material rack 2 and the feed rack 3 have oblique teeth on both sides of the top. The oblique teeth design can not only make the edge of the regular oblique tube filler stuck in the tooth groove of the material rack 2 to play a role in placing and supporting the filler, but also in the process of the feed rack 3 conveying the filler, the filler will slide into the tooth groove of the material rack through the oblique edge of the oblique teeth, so that the conveying is smoother. A driving rod is fixedly mounted at the bottom of the feed rack 3 and a slide plate 301 is fixedly mounted at the bottom of the driving rod. Figure 4 In the embodiment, the vertical sides of the oblique teeth arranged on the material rack 2 and the material feeding rack 3 are both provided with inverted teeth. When the edge of the filler is inserted into the tooth groove of the material rack 2, the center of gravity of the filler will be offset due to the oblique tube arrangement. In the event of severe vibration or collision, the filler will fall over. The inverted teeth are designed to limit the rotation of the filler, so that the filler can only move in the vertical direction to prevent the filler from falling over. The stability of material placement and feeding is also improved.

[0045] A feeding assembly 4 installed inside the welding table 1 and used to drive the feeding frame 3 to feed the filler;

[0046] A plurality of clamp welding assemblies 5 for filler welding are equidistantly installed at the bottom of the material rack 2;

[0047] A detection component 6 installed in the material rack 2 for detecting filler weld points;

[0048] A variable distance component 7 installed on the material rack 2 for adjusting the clamping welding distance and the detection distance;

[0049] The connecting assembly 8 installed between the clamping welding assembly 5 and the variable pitch assembly 7 is as follows: Figure 4 and Figure 8 In the embodiment, the connecting component 8 is installed between the clamping welding component 5 and the variable distance component 7, so as to achieve the purpose of adjusting the clamping welding distance without interfering with the feeding action.

[0050] like Figure 3In the embodiment, the feeding assembly 4 includes a mounting plate 401, a driving shaft 402 and a connecting rod 403. The mounting plate 401 is fixedly mounted in the welding table 1. The driving shaft 402 is rotatably mounted between the mounting plate 401 and the inner wall of the welding table 1. A motor for driving the driving shaft 402 to rotate is fixedly mounted on the mounting plate 401. A cam 404 and a turntable 405 are fixedly sleeved on the driving shaft 402. The slide plate 301 contacts the cam 404 under the gravity of the feeding rack 3. The connecting rod 403 is movably inserted on the mounting plate 401 and movably sleeved on the driving rod at the same time. A ball head 406 is provided at one end of the connecting rod 403. A connecting rod 403 is installed to make the connecting rod 403 rotate. The ball head 406 is pressed against the spring 407 of the turntable 405, wherein the motor drives the drive shaft 402 to rotate, and the drive shaft 402 can drive the cam 404. The rotation of the cam 404 can indirectly lift the feed rack 3, and the feed rack 3 will drop under the gravity of the feed rack 3, so the feed rack 3 will produce an up and down reciprocating movement, and the end surface of the turntable 405 facing the cam 404 is provided with two high and low annular edges and connected by a sloped edge, wherein the drive shaft 402 drives the cam 404 to rotate and also drives the turntable 405 to rotate, and the turntable 405 rotates (because the end surface of the turntable 405 facing the cam 404 is provided with two high and low annular edges), so as to Figure 3 From the perspective of rotation, when the ball head 406 contacts the higher side of the turntable 405, it will push the feed rack 3 to the left through the connecting rod 403 and compress the spring 407. During the rotation of the turntable 405, the ball head 406 passes through the slope and, under the elastic action of the spring 407, it will push the feed rack 3 to the right through the connecting rod 403 and make the ball head 406 contact the lower side of the turntable 405. Therefore, the overall movement state of the feed rack 3 is first upward and then to the left, then descends and then returns to its original position, and repeats this process to achieve step-by-step transportation of the filler.

[0051] like Figure 5 In the embodiment, the clamping welding assembly 5 includes a slide seat 501, a clamping welding head 502 and a first connecting seat 503. A suspension rod is fixedly welded to the bottom of the feed frame 3 and the first connecting seat 503 is fixedly installed on the suspension rod. Two clamping welding heads 502 are provided and are slidably installed on the slide seat 501 in a mirror image. A connecting rod 504 is slidably installed between the two clamping welding heads 502 and the first connecting seat 503. When the feed assembly 4 drives the feed frame 3 to move upward, it will drive the first connecting seat 503 to move upward. The upward movement of the first connecting seat 503 will drive the two clamping welding heads 502 to move away from each other through the sliding installation effect with the connecting rod 504, and vice versa. Therefore, in conjunction with the conveying action of the filler, after the filler moves down into the tooth groove of the material rack 2, the clamping welding head 502 will clamp the two corrugated plates forming the cross section of the honeycomb hole, so as to realize automatic clamping welding of the filler in conjunction with the feeding action.

[0052] like Figure 6-Figure 8In the embodiment, the detection assembly 6 includes a first slide rail 601, a limiting sleeve 602, a first telescopic sleeve 603, a second telescopic sleeve 604 and a micro imaging probe 605. The first slide rail 601 is fixedly welded in the material rack 2. The limiting sleeve 602 is provided with a plurality of sleeves 603 and is equidistantly slidably installed in the first slide rail 601. The first telescopic sleeve 603 is movably inserted at the bottom of the limiting sleeve 602. The bottom of the first telescopic sleeve 603 is fixedly connected to the first connecting seat 503. The second telescopic sleeve 604 is movably inserted at the top of the limiting sleeve 602 and extends to the first telescopic sleeve 603. The micro imaging probe 605 is The imaging probe 605 is fixedly installed on the top of the second telescopic sleeve 604. The limiting sleeve 602 is provided with a first limiting groove and a driving pin 606 is movably inserted in the first limiting groove. The first telescopic sleeve 603 and the second telescopic sleeve 604 are provided with guide grooves. The driving pin 606 extends to the outside of the limiting sleeve 602 through the guide groove. The backs of the first telescopic sleeve 603 and the second telescopic sleeve 604 are provided with second limiting grooves. The limiting sleeve 602 is provided with a limiting strip 607 that cooperates with the second limiting sliding. The guide grooves are all arc-shaped and mirror-imaged, wherein when the feeding assembly 4 drives the connecting seat in the clamping welding assembly 5 to move up and down, it also drives the first telescopic sleeve 603 to move up and down. When the feeding assembly 4 drives the telescopic sleeve to rise, under the triple limiting action of the guide groove, the first limiting groove and the second limiting groove (the guide groove cooperates with the driving pin 606 to realize the extension and retraction of the first telescopic sleeve 603 and the second telescopic sleeve 604, the first limiting groove horizontally limits the movement of the driving pin 606, and the second limiting groove slides with the limiting strip 607 to limit the movement of the first telescopic sleeve 603 and the second telescopic sleeve 604). The first telescopic sleeve 603 and the second telescopic sleeve 604 are rotated and limited), the first telescopic sleeve 603 and the second telescopic sleeve 604 will be synchronously retracted into the limiting sleeve 602, and the driving pin 606 will rotate horizontally. On the contrary, the first telescopic sleeve 603 moves down and the second telescopic sleeve 604 will also be synchronously extended. Therefore, in conjunction with the delivery of the filler, when the filler is delivered to the next tooth groove, the second telescopic sleeve 604 extends and drives the micro imaging probe 605 to extend into the honeycomb hole of the filler and to be at the same height as the weld, and the weld is imaged and detected by the micro imaging probe 605.

[0053] like Fig.10In the embodiment, the variable pitch component 7 includes a limit plate 701 and a second slide rail 702. The limit plate 701 is fixedly installed in the material rack 2, and the second slide rail 702 is slidably installed in the material rack 2. A plurality of electric push rods 703 for driving the second slide rail 702 to translate are fixedly installed on the top of the limit plate 701. A plurality of second connecting seats 704 are equidistantly slidably installed in the second slide rail 702. A plurality of adjustment grooves 705 are equidistantly provided on the limit plate 701. The plurality of adjustment grooves 705 are distributed in a fan shape, and the adjustment groove 705 in the middle is parallel to the extension and contraction direction of the electric push rod 703. The extension of the electric push rod 703 drives the second slide rail 702 to translate as a whole. By utilizing the sliding action of the second connecting seat 704 and the second slide rail 702, the plurality of second connecting seats 704 will expand and move outward with the center point of the second slide rail 702. At the same time, the spacing between adjacent second connecting seats 704 becomes larger, and vice versa. In this way, the purpose of adjusting the clamping welding spacing is achieved, so as to perform clamping welding on the honeycomb hole design of the filler spacing.

[0054] like Fig.10 and Fig.11 In the embodiment, the connecting assembly 8 includes a third slide rail 801, a support bracket 802 and a sliding sleeve 803. A plurality of first telescopic rods 804 are slidably mounted on the third slide rail 801. The telescopic ends of the first telescopic rods 804 are fixedly connected to the bottom of the first connecting seat 503. The support bracket 802 is fixedly welded in the feed frame 3 to support the first telescopic rods 804. A plurality of sliding sleeves 803 are provided and are respectively slidably mounted on the first telescopic rods 804. A second telescopic rod 805 is fixedly mounted on the top of the sliding sleeve 803. The telescopic end of the second telescopic rod 805 is fixedly connected to the second connecting seat 704. In the process of the feed assembly 4 driving the feed frame 3 to feed materials, the telescopic effect of the first telescopic rod 804 and the second telescopic rod 805 is utilized to prevent interference with the movement of the clamping welding assembly 5. The sliding effect of the sliding sleeve 803 and the first telescopic rod 804 and the sliding effect of the first telescopic rod 804 and the third slide rail 801 are utilized to prevent interference with the movement of the variable pitch assembly 7.

[0055] The specific working principle is that after the stainless steel corrugated plate is regularized into an inclined tube filler with a honeycomb interface, a fixing frame is installed and placed at one end of the material rack 2, and the two sides of the filler are clamped in the tooth grooves of the material rack 2. The cam 404 driven by the motor in the feeding assembly 4 can indirectly lift the feeding rack 3, and the feeding rack 3 will drop under the gravity of the feeding rack 3. Therefore, the feeding rack 3 will produce an up and down reciprocating movement, and at the same time, it will also drive the turntable 405 to rotate. The turntable 405 rotates (because the end surface of the turntable 405 facing the cam 404 is provided with two high and low annular edges), so as to Figure 3From a certain perspective, when the ball head 406 contacts the higher side of the turntable 405, it will push the feeding frame 3 to move to the left through the connecting rod 403 and compress the spring 407. During the rotation of the turntable 405, the ball head 406 passes through the slope, and the elastic action of the spring 407 will push the feeding frame 3 to move to the right through the connecting rod 403, and make the ball head 406 contact the lower side of the turntable 405. Therefore, the overall movement state of the feeding frame 3 is first upward and then to the left, and then descends and then returns to the right, and repeats this way to realize the step-by-step transportation of the filler;

[0056] During the conveying process, when the feeding assembly 4 drives the feeding rack 3 to move upward, it will drive the first connecting seat 503 to move upward. The upward movement of the first connecting seat 503 will drive the two clamping welding heads 502 to move away from each other through the sliding installation effect with the connecting rod 504, and vice versa. Therefore, in coordination with the conveying action of the filler, after the filler moves down into the tooth groove of the material rack 2, the clamping welding head 502 will clamp the two corrugated plates forming the honeycomb hole cross section, so as to realize the automatic clamping welding of the filler in coordination with the feeding action;

[0057] During welding, when the feeding component 4 drives the connecting seat in the clamping welding component 5 to move up and down, it also drives the first telescopic sleeve 603 to move up and down. When the feeding component 4 drives the telescopic sleeve to rise, under the triple limiting action of the guide groove, the first limiting groove and the second limiting groove, the first telescopic sleeve 603 and the second telescopic sleeve 604 will be synchronously retracted into the limiting sleeve 602, and the driving pin 606 will rotate horizontally. On the contrary, when the first telescopic sleeve 603 moves down, the second telescopic sleeve 604 will also be synchronously extended. Therefore, in coordination with the delivery of the filler, when the filler is delivered to the next tooth groove, the second telescopic sleeve 604 extends and drives the micro imaging probe 605 to extend into the honeycomb hole of the filler and be at the same height as the welding point, and the welding point is imaged and detected by the micro imaging probe 605.

[0058] Because the honeycomb holes of the honeycomb stainless steel inclined tube filler are arranged at intervals, after welding one side, it is only necessary to use the external conveying line to convey the filler to the feeding end of the welding table 1. During the conveying process of the filler, the variable pitch assembly 7 is driven to perform variable pitch welding, as follows:

[0059] The extension of the electric push rod 703 drives the second slide rail 702 to move horizontally as a whole. Utilizing the sliding effect of the second connecting seat 704 and the second slide rail 702, multiple second connecting seats 704 will move outward from the center point of the second slide rail 702. At the same time, the spacing between adjacent second connecting seats 704 becomes larger, and vice versa. This achieves the purpose of adjusting the clamping welding spacing, so that clamp welding can be performed on the honeycomb hole design of the filler interval. After welding one end of the filler is completed, the filler should be inverted and the above operation should be repeated. This can achieve continuous batch welding and improve the overall welding efficiency.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
