Description

Technical Field

[0001] The invention relates to the technical field of radiator water tank processing, in particular to special equipment for argon arc welding of a water chamber and a mainboard of a radiator water tank and a production process thereof. Background Art

[0002] The car water tank, also known as the radiator, is the main component in the car cooling system. Its function is to dissipate heat. The traditional radiator is mainly composed of the radiator mainboard, the upper water chamber and the lower water chamber. The upper water chamber is on the radiator, and the water pipe connects the upper water chamber with the water chamber below the radiator. When the hot water flows from top to bottom to the lower water chamber, it becomes warm water. The heat dissipation air blades form a channel. Due to the suction of the fan and the relative wind speed when the car is moving forward, a large amount of cold air passes through the air channel, absorbs the heat of the cooling water flowing through the water pipe, and then dissipates it into the atmosphere.

[0003] In the prior art, the following disadvantages still exist in the process of installing the upper water chamber and the lower water chamber with the radiator mainboard:

[0004] 1. In the prior art, the radiator is fixed together with the radiator mainboard and the water chamber by a pressing method. This method not only causes the connection between the radiator mainboard and the water chamber to be unstable, but also easily causes a gap between the radiator mainboard and the water chamber, affecting the subsequent use;

[0005] 2. When fixing the radiator mainboard and the water chamber together, first connect one water chamber to the radiator mainboard through a clip. During the installation process through the clip, first install two sides of it, then install the other two sides, and then fix the other water chamber in the same way. The operation is very cumbersome, resulting in low installation efficiency.

[0006] In view of the above problems, the present invention document proposes special equipment for argon arc welding of the water chamber and mainboard of the heat dissipation water tank and its production process. Summary of the invention

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1: Reference Figure 1-Figure 3 , a special equipment for argon arc welding, relates to the field of heat sink processing technology, the equipment comprises a bottom plate 1, the top of which is welded with a gantry 16 to form a stable working frame. The top of the bottom plate 1 is rotatably connected with an elliptical plate 2, the design of which facilitates the subsequent rotation operation of the main board 12. A first motor 3 is fixed inside the bottom plate 1, and the output shaft of the first motor 3 is fixedly connected to the bottom of the elliptical plate 2. By starting the first motor 3, the elliptical plate 2 can be driven to rotate, thereby driving the main board 12 placed on the elliptical plate 2 to rotate.

[0047] Reference Figure 3 , Figure 4 and Figure 6 The main board 12 is located above the elliptical plate 2, and two water chambers 13 are respectively arranged at the top and bottom of the main board 12. Seals 14 are provided at the top and bottom of the main board 12, and the seals 14 are located between the water chamber 13 and the main board 12, and are used to enhance the sealing performance between the water chamber 13 and the main board 12 to ensure that no leakage occurs during the welding process. Multiple buckles 15 are fixed at the top and bottom of the main board 12, and the design of the buckles 15 facilitates the clamping and fixing of the water chamber 13 and the main board 12, thereby simplifying the installation steps.

[0048] Reference Figure 5 and Figure 6 In order to realize the positioning and clamping of the main board 12, the device also includes a clamping structure. The clamping structure includes a sliding groove 4 arranged on the top of the elliptical plate 2, and a bidirectional screw 5 is rotatably connected in the sliding groove 4. Two L-shaped movable arms 6 threadedly connected to the bidirectional screw 5 are slidably connected in the sliding groove 4, and the two L-shaped movable arms 6 are respectively located at the positive and negative thread sections of the bidirectional screw 5. When the bidirectional screw 5 rotates, the two L-shaped movable arms 6 will move toward or away from each other. The ends of the two L-shaped movable arms 6 that are close to each other are both rotatably provided with a clamping block 8, and the shape of the clamping block 8 matches the inner wall of the main board 12, which can not only clamp and fix the main board 12, but also position the main board 12. A rotating shaft 7 is rotatably passed through the two L-shaped movable arms 6, and one end of the rotating shaft 7 is fixedly connected to the corresponding clamping block 8. A second motor 9 is fixedly provided on the side of the two L-shaped movable arms 6 that are away from each other, and the output shaft of the second motor 9 is fixedly connected to the rotating shaft 7. By starting the second motor 9, the clamping block 8 and the main board 12 can be driven to rotate, so as to facilitate the fixation of the main board 12 and another water chamber 13 at a later stage.

[0049] Reference Figure 3 , Figure 6 and Figure 7 In order to increase the sealing between the water chamber 13 and the main board 12, the device also includes a pressing structure. The pressing structure includes a cylinder 17 fixedly passing through the gantry 16, and a lifting plate 18 is fixed to the output shaft of the cylinder 17. A plurality of guide rods 19 are fixed to the top of the lifting plate 18, and the top of the guide rod 19 slides through the gantry 16, so as to increase the stability of the lifting and lowering of the lifting plate 18. A plurality of rubber pressing rods 20 are fixed to the bottom of the lifting plate 18, and the design of the rubber pressing rods 20 can ensure that no damage is caused to the main board 12 and the water chamber 13 during the pressing process. When the output shaft of the cylinder 17 is extended, the rubber pressing rods 20 will be driven downward through the lifting plate 18 to press the water chamber 13 on the top of the main board 12, so that the water chamber 13 and the main board 12 are tightly fitted, and the sealing between the main board 12 and the water chamber 13 is ensured under the action of the seal 14.

[0050] Reference Figure 2 , Figure 4 and Figure 8In addition, the device also includes two groups of clamping and welding structures, which are respectively arranged on both sides of the elliptical plate 2. The two groups of structures are used to squeeze the buckle 15, clamp the water chamber 13 and the main board 12, and weld and fix the water chamber 13 and the main board 12 by argon arc welding. The structure includes a moving plate 21 arranged on one side of the elliptical plate 2, and the moving plate 21 can slide on the top of the bottom plate 1. On the side of the moving plate 21 away from the elliptical plate 2, a plurality of sliding rods 22 are fixed. One end of these sliding rods 22 slides through the gantry 16, so that the moving plate 21 is more stable when sliding. At the same time, a plurality of first springs 23 are fixed on one side of the moving plate 21, and these first springs 23 are sleeved on the outer wall of the sliding rod 22, and the other ends thereof are fixedly connected to the inner wall of one side of the gantry 16. In this way, when the moving plate 21 is subjected to external force, it can be buffered and reset by the first springs 23. A hemispherical block 46 is fixed on one side of the moving plate 21 close to the elliptical plate 2 . The hemispherical block 46 cooperates with the elliptical plate 2 . When the elliptical plate 2 moves to a suitable position, the moving plate 21 can be pushed to move.

[0051] Reference Figure 8 and Fig. 9 A supporting plate 24 is provided on the top of the movable plate 21, and a plurality of empty slots 30 arranged side by side are provided in the supporting plate 24. The same rotating rod 31 is rotatably connected in these empty slots 30, and a plurality of arc rods 32 are fixedly passed through the rotating rod 31, and these arc rods 32 are respectively located in the corresponding empty slots 30. The same pressing rod 33 is fixed at the top of the plurality of arc rods 32, and the pressing rod 33 is used to press and bend the buckle 15, so as to clamp the main board 12 with the water chamber 13. In order to ensure that the rotating rod 31 and the pressing rod 33 can be reset and rotated, torsion springs 34 are fixed on the inner wall of the two outermost empty slots 30 away from each other. The two torsion springs 34 are both sleeved on the outer wall of the rotating rod 31, and the ends thereof close to each other are fixedly connected to the outer wall of the rotating rod 31.

[0052] Reference Figure 8-Figure 10In addition, the clamping and welding structure also includes a screw rod 37 that rotates on the top of the bearing plate 24 through a base. The outer wall of the screw rod 37 is threadedly sleeved with a moving block 38, and the moving block 38 slides on the top of the bearing plate 24. A mounting frame 39 is fixed on one side of the moving block 38, and the mounting frame 39 also slides on the top of the bearing plate 24. An argon arc welding gun 40 is fixedly installed in the mounting frame 39, and the argon arc welding gun 40 is used to weld the buckle 15, the main board 12 and the water chamber 13. A base plate 44 is fixed on one side of the mounting frame 39, and a guide rod 41 slides through the base plate 44. An arc plate 43 is fixed to the bottom end of the guide rod 41, and a third spring 42 is fixed between the top of the arc plate 43 and the bottom of the base plate 44, and the third spring 42 is sleeved on the outer wall of the guide rod 41. In this way, when the arc plate 43 is subjected to external force, it can be buffered and reset by the third spring 42. A push ring 35 is sleeved on the outer wall of one of the arc-shaped rods 32 located at the outermost side, and a push plate 36 is fixed to the side of the push ring 35 close to the mounting frame 39, and the push plate 36 slides on the top of the bearing plate 24. The arc surface of the arc plate 43 cooperates with the push plate 36 to drive the arc-shaped rod 32 and the rotating rod 31 to rotate.

[0053] Specifically, first, by rotating the screw 37, the moving block 38, the mounting frame 39, the arc plate 43 and other structures are driven to move to one side. When the arc surface of the arc plate 43 touches the push plate 36, the push ring 35 is pushed to move. The push ring 35 drives the rotating rod 31 and the pressing rod 33 to rotate through the arc rod 32. During the rotation of the pressing rod 33, the multiple buckles 15 on the corresponding side of the top of the main board 12 can be extruded and bent, so that the buckles 15 squeeze and fix the water chamber 13. As the arc plate 43 continues to move, when it releases the extrusion of the push plate 36, the rotating rod 31 and the pressing rod 33 will reset and rotate under the action of the torsion spring 34, and the pressing rod 33 will detach from the buckle 15. At this time, the main board 12, the buckle 15 and the water chamber 13 can be welded by the argon arc welding gun 40.

[0054] Reference Fig.11 In addition, in order to facilitate the reset movement of the arc plate 43, an inclined surface 45 is provided at the bottom of the arc plate 43 near the mounting bracket 39. The inclined surface 45 cooperates with the push plate 36. When the mounting bracket 39 and the arc plate 43 are reset, the push plate 36 cooperates with the inclined surface 45 to drive the arc plate 43 to move upward. In this way, the arc plate 43 can be smoothly moved to the initial position, which is convenient for the next action.

[0055] Reference Figure 8, a hydraulic cylinder 25 is fixedly embedded in the top center position of the movable plate 21. The selection of the hydraulic cylinder 25 ensures that its output shaft has sufficient stability and strength to meet the requirements of the lifting of the load-bearing plate 24. The output shaft of the hydraulic cylinder 25 is directly and fixedly connected to the bottom center position of the load-bearing plate 24. By controlling the extension and contraction of the hydraulic cylinder 25, the lifting height of the load-bearing plate 24 can be accurately controlled. This design enables the equipment to adapt to main boards 12 of different heights, and then accurately fix the water chamber 13. In order to ensure the stability of the load-bearing plate 24 during the lifting process, we have fixedly installed a plurality of diagonal bracing plates 26 on both sides of the bottom of the load-bearing plate 24. The bottom ends of these diagonal bracing plates 26 are designed to be slidably connected to the movable plate 21, such as by using slide rails and sliders to ensure that the load-bearing plate 24 does not shake during lifting and remains stable.

[0056] Reference Figure 5 In order to realize the smooth rotation of the main board 12, a pin rod 10 is fixedly installed on the side where the two L-shaped moving arms 6 are close to each other. At the same time, an annular groove 11 is provided on the side where the two clamping blocks 8 are away from each other. The pin rod 10 is slidably matched with the annular groove 11, that is, the pin rod 10 can move along the track of the annular groove 11. When the L-shaped moving arm 6 drives the clamping block 8 to rotate, the sliding of the pin rod 10 in the annular groove 11 ensures that the clamping block 8 can smoothly drive the main board 12 to rotate, avoiding shaking or jamming during the rotation process.

[0057] Through the above implementation, the device can realize the rapid and accurate clamping, positioning and welding of the water chamber 13 and the main board 12 of the heat dissipation water tank, thereby improving production efficiency and product quality.

[0058] Example 2: Reference Figure 8 and Fig. 9 , based on the improvement of Example 1: on the side of the carrier plate 24 close to the main board 12, we designed an extrusion plate 27. The extrusion plate 27 is used to clamp the top of one side of the main board 12 to ensure the stability of the main board 12 in subsequent operations. In order to achieve this function, we fixedly installed a plurality of plug rods 28 on the side of the extrusion plate 27 close to the carrier plate 24, and one end of these plug rods 28 slides and extends into the carrier plate 24. At the same time, a plurality of second springs 29 are fixedly installed between the extrusion plate 27 and the carrier plate 24, and the second springs 29 are sleeved on the outer wall of the plug rod 28.

[0059] Specifically, when the extrusion plate 27 is subjected to external force (such as the placement of the main board 12), it will compress the second spring 29 and move closer to the support plate 24. However, when the external force disappears, the elastic force of the second spring 29 will push the extrusion plate 27 to reset, thereby clamping the top of one side of the main board 12. This design ensures that after the main boards 12 of different heights are carried by the support plate 24, the extrusion plate 27 can stably clamp the main board 12 under the action of the second spring 29. In particular, when the pressing rod 33 squeezes the buckle 15, the clamping effect of the extrusion plate 27 can further ensure the stability of the main board 12, preventing it from moving or shaking, thereby ensuring the accuracy and quality of argon arc welding.

[0060] The production process of the special equipment for argon arc welding of the water chamber of the heat sink and the mainboard pressing includes the following steps:

[0061] S1. Place the main board 12 between the two clamping blocks 8. Drive the bidirectional screw 5 to rotate through the motor. The bidirectional screw 5 drives the two clamping blocks 8 to move toward the middle, just so that the two clamping blocks 8 extend into the main board 12 and clamp the main board 12. Since the clamping blocks 8 match the main board 12, the main board 12 can be positioned during the clamping process. Then, place the seal 14 and the water chamber 13 on the top of the main board 12 in sequence and between the multiple buckles 15. The main board 12 and the water chamber 13 are preliminarily placed, so that the water chamber 13 can be welded to the top of the main board 12 later.

[0062] S2. The output shaft of the cylinder 17 drives the rubber pressing rod 20 to move downward through the lifting plate 18 to press the water chamber 13 on the top of the main board 12, so that the water chamber 13 and the main board 12 can be tightly fitted, and the sealing between the main board 12 and the water chamber 13 can be ensured under the action of the sealing member 14;

[0063] S3, then the motor drives the screw rod 37 to rotate, the screw rod 37 drives the arc plate 43 and the mounting bracket 39 to move to one side through the moving block 38, the arc surface of the arc plate 43 touches the pushing plate 36 and pushes the pushing ring 35 to move, and the pushing ring 35 drives the rotating rod 31 and the pressing rod 33 to rotate through the arc rod 32, and then during the rotation of the pressing rod 33, multiple buckles 15 on the corresponding side of the top of the main board 12 can be squeezed and bent, so that the buckles 15 squeeze and fix the water chamber 13, with the movement of the arc plate 43, the arc plate 43 releases the squeezing of the pushing plate 36, the rotating rod 31 and the pressing rod 33 are reset and rotated under the action of the torsion spring 34, and the pressing rod 33 is separated from the buckle 15, so that the argon arc welding gun 40 can weld the main board 12, the buckle 15 and the water chamber 13 in the later stage;

[0064] S4. After welding is completed, the screw 37 drives the mounting frame 39 and the arc plate 43 to reset and move, and the push plate 36 cooperates with the inclined surface 45 to drive the arc plate 43 to move upward, so that the arc plate 43 can be smoothly moved to the initial position, which is convenient for the next action;

[0065] S5. After two sides of the main board 12 and the water chamber 13 are fixed and welded, the first motor 3 drives the elliptical plate 2 to rotate 90° to change the direction of the main board 12. When the elliptical plate 2 rotates, its protruding part cooperates with the hemispherical block 46 to push the movable plate 21 and the bearing plate 24 to move to both sides until the elliptical plate 2 and the main board 12 are completely rotated. Since the length and thickness of the elliptical plate 2 are proportionally larger than the main board 12, after the elliptical plate 2 is completely rotated, the distance between the movable plate 21 and the main board 12 is still the same as the previous distance, which is convenient for the later pressing rod 33 to squeeze the buckle 15 and the welding of the argon arc welding gun 40. Then, steps S3 and S4 are repeated to complete the pressing and welding of the other two sides of the main board 12. In addition, the squeezing plate 27 can squeeze the top of one side of the main board 12 under the action of the second spring 29, so as to ensure the stability of the main board 12 when the pressing rod 33 squeezes the buckle 15.

[0066] S6. After one of the water chambers 13 and the main board 12 is fixed and welded, the second motor 9 drives the clamping block 8 to drive the main board 12 to flip 180°, and repeat the above steps to complete the fixing of the main board 12 and the other water chamber 13.

[0067] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 3, the second motor 9, the cylinder 17 and the hydraulic cylinder 25 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
