A welding robot for processing aluminum parts and a method of using the same

Abstract

The invention relates to the technical field of parts processing, and discloses a welding robot for aluminum parts processing and a method of using the same. The robot comprises a base, wherein a motor is rotatably connected to the inner wall of a track of the base, and an output shaft of the motor is fixedly connected to a driving wheel. When in use, the power of the motor is turned on, and the motor drives the roller to roll along the top of the parts through a slide rail and a slider. When the slider rolls, the sliding track is driven to slide up and down along the inner wall of a fixed bracket through a driving column. The sliding track drives the arc-shaped slider to slide along the inner wall of the arc-shaped track through a pressure rod. During this process, the arc-shaped slider forces the swing rod to rotate in a circle with a fulcrum frame. When the arc-shaped slider moves up, the port of the welding gun is forced to swing downward. When the arc-shaped slider moves down, the port of the welding gun tilts upward, so that when the equipment is welding, the welding path presents a "Z"-shaped operation, thereby increasing the welding area of ​​the equipment and reducing the residual welding gap.

[0003] With the diversification of the shapes of parts, when welding the curved outer wall, electric welding or welding along the connecting gap is mostly used. However, in actual application, it is difficult to completely cover all the gaps by the above welding methods, resulting in unreliable welding or the existence of small gaps, which affects the bearing capacity when it is not used in time. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a welding robot for processing aluminum parts, comprising a base, a motor is rotatably connected to the inner wall of the track of the base, the output shaft of the motor is fixedly connected to a driving wheel, the outer wall of the driving wheel is rotatably connected to the inner wall of the base, the top of the motor is fixedly connected to a slide rail, the bottom of the slide rail is fixedly connected to a spring telescopic rod, the other end of the spring telescopic rod is fixedly connected to a slider, and the side wall of the slider is rotatably connected to a roller;

A second feed component is fixedly connected to the inner wall of the mounting plate. In view of the large number of small gaps in linear welding and electric welding, a driving mechanism and a welding mechanism are provided inside the equipment. Before use, put the parts into the center of the inner wall of the base, as shown in the following figure. Figure 1The motor is in the middle G state, and then the power of the motor is turned on. At this time, the motor rotates along the inner wall of the base through the driving wheel, and the motor drives the roller to roll along the top of the component through the slide rail and the slider. When the slider rolls, the driving column drives the sliding track to slide up and down along the inner wall of the fixed bracket, and the sliding track drives the arc slider to slide along the inner wall of the arc track through the pressure rod. In this process, the arc slider will force the swing rod to rotate in a circle with the fulcrum frame as the fulcrum frame. When the arc slider moves up, it forces the port of the welding gun to swing downward, presenting a Figure 5 In the state shown, when the arc-shaped slider moves downward, the port of the welding gun tilts upward. Through the application of the above components, the welding path of the equipment presents a "Z" shape when welding, which increases the welding area of ​​the equipment and reduces the residual welding gap.

[0007] Preferably, the limiting component includes a right-angle frame fixedly connected to the side wall of the mounting plate, a roller is rotatably connected to the side wall of the welding gun, a compression spring is fixedly connected to the outer wall of the welding gun, one end of the compression spring away from the welding gun is fixedly connected to the inner wall of the swing arm, and a first feeding component is slidably connected to the inner wall of the right-angle frame. The limiting component is arranged inside the equipment by utilizing the characteristic that the swing arm drives the welding gun to swing regularly. During the swinging process of the welding gun, the compression spring is compressed, which will always generate an outward pushing force, forcing the roller to move along the outer wall of the right-angle frame, wherein the outer wall of the right-angle frame is parallel to the welding position of the component, such as Figure 6 As shown, during the swinging process of the swinging rod, the roller will slide along the outer wall of the right-angle frame. The roller will ensure that the distance between the welding gun and the outer wall of the part is always equal, ensuring that the welding thickness is equal when the equipment is welding.

[0008] Preferably, the first feeding assembly includes a sliding square plate 1 slidably connected to the inner wall of the right-angle frame, a fixed frame 1 is fixedly connected to the side wall of the sliding square plate 1, and a plurality of inclined spring sheets 1 are fixedly connected to the inner wall of the fixed frame 1.

[0009] Preferably, the first feeding assembly also includes a limiting frame 1 fixedly connected to the side wall of the right-angle frame, a pushing rod 1 is fixedly connected to the side wall of the limiting frame 1, a clamping block 1 is fixedly connected to the other end of the pushing rod 1, a return spring 1 is fixedly connected to the top of the sliding square plate 1, and a raw material wheel 1 is fixedly connected to the top of the fixed bracket. Utilizing the swinging characteristics of the above-mentioned welding gun, the first feeding assembly and the second feeding assembly are arranged inside the equipment. Before the equipment is used, the aluminum strip of the raw material wheel 1 needs to be passed through the fixing frame 1 and the limiting frame 1, and the raw material wheel 1 is presented as follows: Figure 8The state shown, wherein, when the welding gun moves upward, the welding gun will contact the bottom of the sliding square plate 1, forcing the sliding square plate 1 to slide upward along the inner wall of the right-angle frame and squeeze the return spring 1. In this process, due to the influence of the inclination angle of the limited inclined spring piece 1, the inclined spring piece 1 cannot limit the aluminum strip, and the inclined spring piece 1 will slide upward along the outer wall of the aluminum strip. At this time, the bottom of the aluminum strip will contact the outer wall of the welding gun, and the welding gun melts the aluminum strip to complete the feeding. When the welding gun swings downward, the return spring 1 will release the mechanical power, forcing the sliding square plate 1 to slide downward along the inner wall of the right-angle frame. The sliding square plate 1 drives the inclined spring piece 1 to move downward synchronously through the fixed frame 1, and due to the influence of the inclination angle of the limited inclined spring piece 1, the two clamped inclined spring pieces 1 will clamp the aluminum strip and slide downward, as shown in FIG. Fig. 9 state; in addition, when the welding gun swings downward, it pushes the sliding square plate 2 to slide and contact the aluminum bar of the raw material wheel 2 to complete the welding, and when the welding gun is moved away, the reset spring 2 drives the sliding square plate 2 to reset to complete the feeding. Through the application of the above components, the stability of the single feeding of the equipment is guaranteed, and the feeding deviation is avoided, which leads to uneven welding thickness.

[0010] Preferably, the second feeding assembly includes a sliding square plate 2 slidably connected to the inner wall of the mounting plate, a return spring 2 is fixedly connected to the side wall of the sliding square plate 2, a fixing frame 2 is fixedly connected to the bottom of the sliding square plate 2, and a bevel spring piece 2 is fixedly connected to the inner wall of the arc-shaped slider.

[0011] Preferably, the second feeding assembly also includes a limiting frame 2 fixedly connected to the bottom of the mounting plate, a pushing rod 2 is fixedly connected to the inner wall of the limiting frame 2, the other end of the pushing rod 2 is fixedly connected to a clamping block 2, and a raw material wheel 2 is fixedly connected to the inner wall of the mounting plate. The characteristics of the above-mentioned inclined spring piece 1 and inclined spring piece 2 in driving the feeding of the aluminum bar are utilized, and a clamping block 2 is arranged inside the equipment. When the sliding square plate 1 moves upward and the inclined spring piece 1 moves upward along the outer wall of the aluminum bar, the two clamping blocks 1 will clamp and limit the aluminum bar to avoid the clamping force generated between the inclined spring pieces 1 and the contact force between the welding gun and the aluminum bar when the two inclined spring pieces 1 move upward along the aluminum bar, which causes the aluminum bar to move upward, resulting in differences in feeding, thereby ensuring the stability of the equipment feeding.

[0012] Preferably, the other end of the second reset spring is fixedly connected to the inner wall of the mounting plate, the outer wall of the sliding track is slidably connected to the inner wall of the fixed bracket, and the outer wall of the slider is slidably connected to the inner wall of the slide rail.

[0013] A method for using a welding robot for processing aluminum parts includes the following steps:

[0014] S1: put in parts;

[0015] S2: Turn on the power;

[0016] S3: Perform welding.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention is aimed at linear welding and electric welding with many small gaps. A driving mechanism and a welding mechanism are arranged inside the device. Before use, the parts are placed in the center of the inner wall of the base, and the parts are presented as follows: Figure 1 The motor is in the middle G state, and then the power of the motor is turned on. At this time, the motor rotates along the inner wall of the base through the driving wheel, and the motor drives the roller to roll along the top of the component through the slide rail and the slider. When the slider rolls, the driving column drives the sliding track to slide up and down along the inner wall of the fixed bracket, and the sliding track drives the arc slider to slide along the inner wall of the arc track through the pressure rod. In this process, the arc slider will force the swing rod to rotate in a circle with the fulcrum frame as the fulcrum frame. When the arc slider moves up, it forces the port of the welding gun to swing downward, presenting a Figure 5 In the state shown, when the arc-shaped slider moves downward, the port of the welding gun tilts upward. Through the application of the above components, the welding path of the equipment presents a "Z" shape when welding, which increases the welding area of ​​the equipment and reduces the residual welding gap.

[0019] (2) The present invention utilizes the characteristic that the swing rod drives the welding gun to swing regularly. A limiting component is arranged inside the device. During the swinging process of the welding gun, the compression spring is compressed, and an outward pushing force is always generated, forcing the roller to move along the outer wall of the right-angle frame, wherein the outer wall of the right-angle frame is parallel to the welding position of the component, such as Figure 6 As shown, during the swinging process of the swinging rod, the roller will slide along the outer wall of the right-angle frame. The roller will ensure that the distance between the welding gun and the outer wall of the part is always equal, ensuring that the welding thickness is equal when the equipment is welding.

[0020] (3) The present invention utilizes the swinging characteristics of the welding gun and sets a first feeding assembly and a second feeding assembly inside the equipment. Before the equipment is used, the aluminum strip of the raw material wheel 1 needs to pass through the fixing frame 1 and the limiting frame 1, and present the following Figure 8 The state shown, wherein, when the welding gun moves upward, the welding gun will contact the bottom of the sliding square plate 1, forcing the sliding square plate 1 to slide upward along the inner wall of the right-angle frame and squeeze the return spring 1. In this process, due to the influence of the inclination angle of the limited inclined spring piece 1, the inclined spring piece 1 cannot limit the aluminum strip, and the inclined spring piece 1 will slide upward along the outer wall of the aluminum strip. At this time, the bottom of the aluminum strip will contact the outer wall of the welding gun, and the welding gun melts the aluminum strip to complete the feeding. When the welding gun swings downward, the return spring 1 will release the mechanical power, forcing the sliding square plate 1 to slide downward along the inner wall of the right-angle frame. The sliding square plate 1 drives the inclined spring piece 1 to move downward synchronously through the fixed frame 1, and due to the influence of the inclination angle of the limited inclined spring piece 1, the two clamped inclined spring pieces 1 will clamp the aluminum strip and slide downward, as shown in FIG. Fig. 9 state; in addition, when the welding gun swings downward, it pushes the sliding square plate 2 to slide and contact the aluminum bar of the raw material wheel 2 to complete the welding, and when the welding gun is moved away, the reset spring 2 drives the sliding square plate 2 to reset to complete the feeding. Through the application of the above components, the stability of the single feeding of the equipment is guaranteed, and the feeding deviation is avoided, which leads to uneven welding thickness.

[0021] (4) The present invention utilizes the characteristics of the above-mentioned inclined spring piece 1 and inclined spring piece 2 to drive the aluminum strip to be fed into the material. A clamping block 2 is arranged inside the equipment. When the sliding square plate 1 moves upward, the inclined spring piece 1 moves upward along the outer wall of the aluminum strip. The two clamping blocks 1 clamp and limit the aluminum strip to avoid the clamping force generated between the inclined spring pieces 1 and the contact force between the welding gun and the aluminum strip when the two inclined spring pieces 1 move upward along the aluminum strip, causing the aluminum strip to move upward and causing feeding differences, thereby ensuring the stability of the equipment feeding.

[0040] The welding mechanism 3 includes a mounting plate 31 fixedly connected to the side wall of the fixed bracket 21, a curved track 32 is fixedly connected to the top of the mounting plate 31, a curved slider 33 is slidably connected to the inner wall of the curved track 32, the top of the curved slider 33 is rotatably connected to the bottom of the pressure rod 26, a swing rod 34 is rotatably connected to the inner wall of the curved slider 33, a welding gun 35 is slidably connected to the inner wall of the swing rod 34, a fulcrum frame 36 is fixedly connected to the top of the mounting plate 31, the inner wall of the fulcrum frame 36 is rotatably connected to the outer wall of the swing rod 34, and a limiting component 4 is fixedly connected to the side wall of the mounting plate 31. A second feed component 6 is fixedly connected to the inner wall of the mounting plate 31. In view of the large number of small gaps in linear welding and electric welding, a driving mechanism 2 and a welding mechanism 3 are provided inside the device. Before use, put the parts into the center of the inner wall of the base 1, as shown in the following figure. Figure 1 The motor 11 is in the middle G state, and then the power supply of the motor 11 is turned on. At this time, the motor 11 rotates along the inner wall of the base 1 through the driving wheel 16, and the motor 11 drives the roller 15 to roll along the top of the component through the slide rail 12 and the slider 14. When the slider 14 rolls, the sliding track 24 is driven by the driving column 23 to slide up and down along the inner wall of the fixed bracket 21. The sliding track 24 drives the arc-shaped slider 33 to slide along the inner wall of the arc-shaped track 32 through the pressure rod 26. In this process, the arc-shaped slider 33 will force the swing rod 34 to rotate in a circle with the fulcrum frame 36 as a circle. When the arc-shaped slider 33 moves up, it forces the port of the welding gun 35 to swing downward, presenting a Figure 5 In the state shown, when the arc-shaped slider 33 moves downward, the port of the welding gun 35 tilts upward. Through the application of the above-mentioned components, the welding path of the equipment presents a "Z" shape when welding, which increases the welding area of ​​the equipment and reduces the residual welding gap.

[0041] For example 2, please refer to Figure 6 - Fig.12The present invention is a welding robot for processing aluminum parts. On the basis of the first embodiment, the limiting component 4 includes a right-angle frame 41 fixedly connected to the side wall of the mounting plate 31, a roller 42 is rotatably connected to the side wall of the welding gun 35, a compression spring 43 is fixedly connected to the outer wall of the welding gun 35, and one end of the compression spring 43 away from the welding gun 35 is fixedly connected to the inner wall of the swing rod 34, and a first feeding component 5 is slidably connected to the inner wall of the right-angle frame 41. The characteristic that the swing rod 34 drives the welding gun 35 to swing regularly is utilized, and a limiting component 4 is arranged inside the equipment. During the swinging process of the welding gun 35, the compression spring 43 is compressed, and an outward pushing force will always be generated, forcing the roller 42 to move along the outer wall of the right-angle frame 41, wherein the outer wall of the right-angle frame 41 is parallel to the welding position of the parts, such as Figure 6 As shown, during the swinging process of the swinging rod 34, the roller 42 will slide along the outer wall of the right-angle frame 41. The roller 42 will ensure that the distance between the welding gun 35 and the outer wall of the part is always equal, ensuring that the welding thickness is equal when the equipment is welding.

[0042] The first feeding assembly 5 includes a sliding square plate 51 slidably connected to the inner wall of the right-angle frame 41 , a fixing frame 52 is fixedly connected to the side wall of the sliding square plate 51 , and a plurality of inclined spring sheets 53 are fixedly connected to the inner wall of the fixing frame 52 .

[0043] The first feeding assembly 5 also includes a limiting frame 54 fixedly connected to the side wall of the right-angle frame 41, a pushing rod 55 is fixedly connected to the side wall of the limiting frame 54, and the other end of the pushing rod 55 is fixedly connected to a clamping block 56, a return spring 57 is fixedly connected to the top of the sliding square plate 51, and a raw material wheel 58 is fixedly connected to the top of the fixed bracket 21. By utilizing the swinging characteristics of the above-mentioned welding gun 35, the first feeding assembly 5 and the second feeding assembly 6 are arranged inside the equipment. Before the equipment is used, the aluminum strip of the raw material wheel 58 needs to be passed through the fixing frame 52 and the limiting frame 54, presenting as shown in the figure. Figure 8 The state shown, wherein when the welding gun 35 moves upward, the welding gun 35 will contact the bottom of the sliding square plate 51, forcing the sliding square plate 51 to slide upward along the inner wall of the right-angle frame 41 and squeeze the return spring 57. In this process, due to the influence of the inclination angle of the limited inclined spring piece 53, the inclined spring piece 53 cannot limit the aluminum strip, and the inclined spring piece 53 will slide upward along the outer wall of the aluminum strip. At this time, the bottom of the aluminum strip will contact the outer wall of the welding gun 35, and the welding gun 35 melts the aluminum strip to complete the feeding. When the welding gun 35 swings downward, the return spring 57 will release the mechanical power, forcing the sliding square plate 51 to slide downward along the inner wall of the right-angle frame 41. The sliding square plate 51 drives the inclined spring piece 53 to move downward synchronously through the fixed frame 52. However, due to the influence of the inclination angle of the limited inclined spring piece 53, the two clamped inclined spring pieces 53 will clamp the aluminum strip and slide downward. Fig. 9in addition, when the welding gun 35 swings downward, it pushes the sliding square plate 61 to slide and contact the aluminum bar of the raw material wheel 68 to complete the welding, and when the welding gun 35 is away, the reset spring 62 drives the sliding square plate 61 to reset and complete the feeding. Through the application of the above components, the stability of the single feeding of the equipment is guaranteed, and the feeding deviation is avoided, which leads to uneven welding thickness.

[0044] The second feeding assembly 6 includes a sliding square plate 61 slidably connected to the inner wall of the mounting plate 31, a return spring 62 is fixedly connected to the side wall of the sliding square plate 61, a fixing frame 63 is fixedly connected to the bottom of the sliding square plate 61, and a sloped spring piece 64 is fixedly connected to the inner wall of the arc-shaped slider 33.

[0045] The second feeding assembly 6 also includes a limiting frame 2 65 fixedly connected to the bottom of the mounting plate 31, a pushing rod 2 66 is fixedly connected to the inner wall of the limiting frame 2 65, and the other end of the pushing rod 2 66 is fixedly connected to a clamping block 2 67, and a raw material wheel 2 68 is fixedly connected to the inner wall of the mounting plate 31. The characteristics of the above-mentioned inclined spring piece 1 53 and the inclined spring piece 2 64 driving the aluminum strip to feed the material are utilized, and 56 and a clamping block 2 67 are arranged inside the equipment. When the sliding square plate 1 51 moves upward and the inclined spring piece 1 53 moves upward along the outer wall of the aluminum strip, the two clamping blocks 1 56 will clamp and limit the aluminum strip, so as to avoid the clamping force generated between the inclined spring pieces 1 53 and the contact force between the welding gun 35 and the aluminum strip when the two inclined spring pieces 53 move upward along the aluminum strip, which causes the aluminum strip to move upward, resulting in differences in feeding, thereby ensuring the stability of the equipment feeding.

[0046] The other end of the second return spring 62 is fixedly connected to the inner wall of the mounting plate 31 , the outer wall of the sliding track 24 is slidably connected to the inner wall of the fixed bracket 21 , and the outer wall of the slider 14 is slidably connected to the inner wall of the slide rail 12 .

[0047] The method of using the welding robot includes the following steps:

[0048] S1: put in parts;

[0049] S2: Turn on the power;

[0050] S3: Perform welding.

[0051] A specific application of this embodiment is: before use, the parts are placed in the center of the inner wall of the base 1, and the parts are presented as follows: Figure 1The motor 11 is in the middle G state, and then the power supply of the motor 11 is turned on. At this time, the motor 11 rotates along the inner wall of the base 1 through the driving wheel 16, and the motor 11 drives the roller 15 to roll along the top of the component through the slide rail 12 and the slider 14. When the slider 14 rolls, the sliding track 24 is driven by the driving column 23 to slide up and down along the inner wall of the fixed bracket 21. The sliding track 24 drives the arc-shaped slider 33 to slide along the inner wall of the arc-shaped track 32 through the pressure rod 26. In this process, the arc-shaped slider 33 will force the swing rod 34 to rotate in a circle with the fulcrum frame 36 as a circle. When the arc-shaped slider 33 moves up, it forces the port of the welding gun 35 to swing downward, presenting a Figure 5 In the state shown, when the arc-shaped slider 33 moves downward, the port of the welding gun 35 tilts upward. Through the application of the above-mentioned components, the welding path of the equipment presents a "Z" shape when welding, which increases the welding area of ​​the equipment and reduces the residual welding gap.

[0052] Taking advantage of the characteristic that the swing rod 34 drives the welding gun 35 to swing regularly, a limiting component 4 is provided inside the device. During the swinging process of the welding gun 35, the compression spring 43 is compressed, and an outward pushing force is always generated, forcing the roller 42 to move along the outer wall of the right-angle frame 41, wherein the outer wall of the right-angle frame 41 is parallel to the welding position of the component, such as Figure 6 As shown, during the swinging process of the swinging rod 34, the roller 42 will slide along the outer wall of the right-angle frame 41. The roller 42 will ensure that the distance between the welding gun 35 and the outer wall of the part is always equal, ensuring that the welding thickness is equal when the equipment is welding.

[0053] Taking advantage of the swinging characteristics of the welding gun 35, a first feeding assembly 5 and a second feeding assembly 6 are arranged inside the equipment. Before the equipment is used, the aluminum strip of the raw material wheel 58 needs to be passed through the fixing frame 52 and the limiting frame 54 to present the following Figure 8 The state shown, wherein when the welding gun 35 moves upward, the welding gun 35 will contact the bottom of the sliding square plate 51, forcing the sliding square plate 51 to slide upward along the inner wall of the right-angle frame 41 and squeeze the return spring 57. In this process, due to the influence of the inclination angle of the limited inclined spring piece 53, the inclined spring piece 53 cannot limit the aluminum strip, and the inclined spring piece 53 will slide upward along the outer wall of the aluminum strip. At this time, the bottom of the aluminum strip will contact the outer wall of the welding gun 35, and the welding gun 35 melts the aluminum strip to complete the feeding. When the welding gun 35 swings downward, the return spring 57 will release the mechanical power, forcing the sliding square plate 51 to slide downward along the inner wall of the right-angle frame 41. The sliding square plate 51 drives the inclined spring piece 53 to move downward synchronously through the fixed frame 52. However, due to the influence of the inclination angle of the limited inclined spring piece 53, the two clamped inclined spring pieces 53 will clamp the aluminum strip and slide downward. Fig. 9state; in addition, when the welding gun 35 swings downward, it pushes the sliding square plate 2 61 to slide and contact the aluminum strip of the raw material wheel 2 68 to complete welding, and when the welding gun 35 is away, the reset spring 2 62 drives the sliding square plate 2 61 to reset and complete the feeding. Through the application of the above-mentioned components, the stability of the single feeding of the equipment is guaranteed, and the feeding deviation is avoided, which leads to uneven welding thickness. The characteristics of the above-mentioned inclined spring piece 1 53 and the inclined spring piece 2 64 driving the aluminum strip to feed the material are utilized. 56 and the clamping block 2 67 are arranged inside the equipment. When the sliding square plate 1 51 moves upward, the inclined spring piece 1 53 moves upward along the outer wall of the aluminum strip, and the two clamping blocks 1 56 will clamp and limit the aluminum strip to avoid the clamping force generated between the inclined spring pieces 1 53 and the contact force between the welding gun 35 and the aluminum strip when the two inclined spring pieces 1 53 move upward along the aluminum strip, causing the aluminum strip to move upward, resulting in feeding differences, thereby ensuring the stability of the equipment feeding.
