Description

Technical Field

[0002] In construction projects, welding equipment is a very important tool used to connect various metal components, such as steel structures, pipes, guardrails, etc. Choosing appropriate welding equipment and mastering correct welding techniques are essential to ensure the safety and durability of the structure.

[0003] In the process of welding two sections of cylindrical tubes into a T-shaped connector using automatic wire feeding welding equipment, two workers are often required to cooperate in the process. One of them holds the two cylindrical tubes, and the other welds the connection between the two cylindrical tubes. During the welding process, the worker controls the welding equipment to move along the weld track. Since the weld track is annular, the worker needs to rotate around the cylindrical tube during the welding process. During this processing, it is difficult to control the angle between the welding head and the weld, which can easily cause the angle of the welding head pointing to the weld to continue to change, causing the weld point to deviate from the center of the weld, affecting the connection strength between the two cylindrical tubes after welding.

DETAILED DESCRIPTION

Obviously, the drawings in the following description only relate to some embodiments of the present invention, but are not intended to limit the present invention.

[0059] Example 1: A self-fixing automatic welding device for construction engineering, referring to Figure 1-Figure 4 As shown, it includes: a first bracket 1; a second bracket 11, which is slidably arranged on the first bracket 1, the first bracket 1 and the second bracket 11 cooperate to form a circular track, and the first bracket 1 and the second bracket 11 are both installed with a fixing frame 111; a first sliding rod 12, which is limitedly slidably arranged on the second bracket 11, the first sliding rod 12 is slidably arranged with a second sliding rod 13, and a tension spring is installed between the second sliding rod 13 and the first sliding rod 12; a welding unit 131, which is installed on an adjacent fixing frame 111, and the welding head in the welding unit 131 is installed On the second sliding rod 13; the first sliding frame 15 is slidably set on the second bracket 11; the second sliding frame 151 is slidably set on the first bracket 1, and the first sliding frame 15 and the second sliding frame 151 are both located on the annular track formed by the first bracket 1 and the second bracket 11 to slide, and the first sliding frame 15 and the second sliding frame 151 are both rotatably set with two symmetrical swing plates 16, and the two swing plates 16 cooperate to form a ring; a synchronization mechanism is set on the first bracket 1, and the synchronization mechanism is used to control the second sliding rod 13 to move along a specified track.

[0060] In the above scheme, the welding unit 131 is an automatic wire feeding welding device, and a control panel is provided on the welding unit 131. The control panel of the welding unit 131 is electrically connected to all the electrical components in the present invention. Figure 1In this state, the tension spring between the second sliding rod 13 and the first sliding rod 12 is in a stretched state, and the lower ends of the two adjacent swing plates 16 are quickly fixed by U-shaped buckles. Figure 4 It is a schematic diagram of the first bracket 1 and the second bracket 11 in an open state, wherein the rear portion of the first bracket 1 and the rear portion of the second bracket 11 are two staggered U-shaped rods.

[0061] Reference Figure 2-Figure 4 As shown, the welding head on the welding unit 131 is tilted to allow the welding wire to weld the weld at a suitable angle; a limit block 113 is slidably provided on the first bracket 1, and a spring is installed between the limit block 113 and the first bracket 1, and the limit block 113 is used to lock the position of the first bracket 1 and the second bracket 11 after matching; the first bracket 1 and the second bracket 11 are both slidably provided with a plurality of first sliding columns 112, and tension springs are installed between the first bracket 1 and the second bracket 11 and the adjacent first sliding columns 112, all the first sliding columns 112 are equidistantly distributed in the circumferential direction, and all the opposite sides of the first sliding columns 112 are installed with a plurality of second sliding columns 161, and a spring is installed between the second sliding column 161 and the adjacent swing plate 16, and all the second sliding columns 161 on the two adjacent swing plates 16 are equidistantly distributed in the circumferential direction.

[0062] In the above scheme, the spring between the limit block 113 and the first bracket 1 is in a compressed state, a boss is provided at the other end of the first bracket 1, and a limit hole is provided at the other end of the second bracket 11. The boss of the first bracket 1 is limitedly matched with the limit hole of the second bracket 11, and the limit block 113 is located at the boss of the first bracket 1. An inclined surface is provided on the side of the limit block 113 close to the second bracket 11, so that the boss of the first bracket 1 is quickly inserted into the limit hole of the second bracket 11, and then the limit block 113 is connected to the elastic force of the spring, and the limit block 113 limits the second bracket 11, so that the two first The bracket 1 and the second bracket 11 quickly complete the locking of the workpiece to be processed. To unlock the first bracket 1 and the second bracket 11, it is only necessary to press the limit block 113 and pull the two apart. The inclination of the welding head on the welding unit 131 allows the welding wire to be welded at an appropriate angle, which is convenient for the operator to better see the molten pool and more easily control the welding process. At the same time, a reasonable welding wire angle can reduce spatter during welding and improve the safety and cleanliness of the working environment. In the actual welding process, the heat input can be controlled by adjusting the welding wire angle, the heat affected zone can be reduced, and the deformation and thermal damage of the parent material can be reduced.

[0063] In the attached Figure 1In this state, the tension spring connected to the first sliding column 112 and the tension spring connected to the second sliding column 161 are both in a stretched state, and all the second sliding columns 161 are divided into two groups that are symmetrical on the left and right. The circumferentially distributed first sliding columns 112 and the circumferentially equidistantly distributed second sliding columns 161 are both used to centrally clamp the workpiece to be processed, so that the center lines of the two workpieces to be processed are perpendicular, thereby improving the applicability of the device. The ball on the first sliding column 112 is used to reduce the friction between it and the clamping part, which facilitates the rotation of the T-shaped connecting part after assembly, so that the welding unit 131 can continuously weld the connection between the two workpieces to be processed.

[0064] Reference Figure 1-Figure 3 As shown, the synchronization mechanism includes: a third sliding rod 2, which is slidingly arranged on the first bracket 1 in a limited manner; a fourth sliding rod 21, which is slidingly arranged on the third sliding rod 2 in a limited manner, and the second sliding rod 13 and the fourth sliding rod 21 are both provided with ball bearings; a first arc plate 22, which is fixedly connected to the end of the third sliding rod 2 away from the fourth sliding rod 21, and a tension spring is installed between the first bracket 1, and a convex column is provided on the first arc plate 22; a second arc plate 23, which is arranged at the end of the first sliding rod 12 away from the second sliding rod 13, and a tension spring is installed between the second bracket 11, and the second arc plate 23 is provided with a blind hole, and the blind hole of the second arc plate 23 is limitedly matched with the convex column of the first arc plate 22.

[0065] In the above scheme, the fourth sliding rod 21 is provided with a tilting probe, and the lower end of the tilting probe on the fourth sliding rod 21 is slightly lower than the lower end of the welding head on the welding unit 131, so that when the second curved plate 23 and the first curved plate 22 are in a coordinated state, when the tilting probe on the fourth sliding rod 21 is in contact with the workpiece to be processed, the fourth sliding rod 21 is transmitted through the first curved plate 22, the second curved plate 23 and the first sliding rod 12 to make the welding head on the welding unit 131 suspended at the welds of the two workpieces to be processed, so as to facilitate the welding unit 131 to perform continuous and reliable welding on the welds.

[0066] Working principle: Two cylindrical tubes to be processed are fixed between all the first sliding columns 112 and between two sets of second sliding columns 161, so that the two cylindrical tubes are in a T shape (the state of the two cylindrical tubes to be processed after assembly is attached). Figure 1As shown in , after installation, the fourth sliding rod 21 is attached to the two cylindrical tubes to be processed, and the left end of the second sliding rod 13 is attached to the adjacent cylindrical tube to be processed, and then the welding unit 131 is started through the control panel. The welding unit 131 first performs spot welding at equal intervals on the welds of the two cylindrical tubes to complete the pre-connection of the two cylindrical tubes. Subsequently, the welding unit 131 works to uniformly spit wire to weld the connection of the two cylindrical tubes. During the welding process, the operator rotates the vertical cylindrical tube, and the vertical cylindrical rod drives the horizontal cylindrical tube, the two sets of swing plates 16, The first sliding frame 15 and the second sliding frame 151 rotate around the first bracket 1 and the second bracket 11. During the rotation of the two cylindrical tubes, the fourth sliding rod 21 moves along the weld of the two cylindrical tubes under the tension of the tension spring connected to the third sliding rod 2. The fourth sliding rod 21 drives the second sliding rod 13 to move together through the third sliding rod 2, the first curved plate 22, the second curved plate 23 and the first sliding rod 12, and controls the welding head of the welding unit 131 on the second sliding rod 13 to continuously weld the welds of the two cylindrical tubes (the weld between the two cylindrical tubes is shown in the attached figure). Figure 1 As shown in FIG. 1 , the welding process of the T-shaped connector is completed. After the welding is completed, the connection between the first bracket 1 and the second bracket 11 and the connection between the two sets of swing plates 16 are released, and the T-shaped connector can be taken out.

[0067] Example 2: Based on Example 1, refer to Figure 1 , Figure 3 and Figure 5 As shown, it also includes: a driving mechanism, which is arranged on the first sliding frame 15, and the driving mechanism is used to drive the first sliding frame 15 to move at a variable speed, so as to control the welding head of the welding unit 131 to move at a relatively uniform speed, and the driving mechanism includes: a motor 3, which is fixedly connected to the first sliding frame 15, and its output shaft is fixedly connected to a round table wheel 31; a rotating sleeve 32, which is rotatably arranged on the first sliding frame 15, and a gear is installed on the rotating sleeve 32; a rotating shaft 33, which is limitedly slidably arranged in the rotating sleeve 32, and the rotating shaft 33 is located on the side wall outside the rotating sleeve 32 and is fixedly connected to a rotating shaft. Wheel 34, the rotating wheel 34 is in transmission cooperation with the truncated cone wheel 31; the connecting frame 35 is rotatably set on the rotating shaft 33 and is slidably connected with the second arc plate 23; there are two arc racks 36, and the two second arc plates 23 are respectively fixed to the first bracket 1 and the second bracket 11, and the two arc racks 36 cooperate to form a gear ring, and the gear on the rotating sleeve 32 is meshed with the gear ring composed of the two arc racks 36; the sum of the tension of the tension spring connected to the first arc plate 22 and the second arc plate 23 in the stretched state is greater than the friction between the truncated cone wheel 31 and the rotating wheel 34.

[0068] In the above scheme, the cross-section of the frustum wheel 31 gradually decreases from top to bottom. During the processing of cylindrical tubes of different sizes, different working modes of the motor 3 can be selected on the control panel, and the transmission ratio between the frustum wheel 31 and the rotating wheel 34 can be adjusted to make the output shaft of the motor 3 rotate at different speeds. The auxiliary welding unit 131 performs uniform speed welding on the connection between the two cylindrical tubes, and the motor 3 is electrically connected to a fixed power supply.

[0069] Working principle: Figure 1 From the shape of the weld between the two cylindrical tubes, it can be seen that the weld trajectory is annular and wavy, that is, the weld changes more and more in the vertical direction. In order to ensure that the device performs uniform welding on the weld trajectory, it is necessary to change the moving speed of the welding head on the welding unit 131 in different areas of the weld trajectory. The specific implementation method is as follows:

[0070] During the welding process of two cylindrical tubes, the two cylindrical tubes are installed between all the first sliding columns 112 and between the two groups of second sliding columns 161, and then the motor 3 and the welding unit 131 are started through the control panel. The welding unit 131 works to weld and fix the weld, and the motor 3 drives the round table wheel 31 to rotate at a uniform speed. The round table wheel 31 drives the rotating sleeve 32 and the gear thereon to rotate through the rotating wheel 34 and the rotating shaft 33. The gear rotates around the arc rack 36. The rotating sleeve 32 moves to make the first sliding frame 15 move on the annular track formed by the first bracket 1 and the second bracket 11. The first sliding frame 15 drives the cylindrical tube to rotate through the adjacent swing plate 16 and the second sliding column 161. Since the two cylindrical tubes are pre-connected and fixed under the spot welding operation, the two cylindrical tubes rotate together, and at the same time, the third sliding rod 2 and other components are moved downward to make the welding head of the welding unit 131 move along the weld.

[0071] During the welding process of the welding head on the welding unit 131, the welding track is welded. Figure 1 In the state of the two cylindrical tubes, the two cylindrical tubes rotate clockwise (in the adjacent Figure 1 As can be seen from the top down in the figure, the fourth sliding rod 21 moves closely against the surface of the cylindrical tube, so that the fourth sliding rod 21 moves downward in the vertical direction. During the movement of the fourth sliding rod 21 through the third sliding rod 2 and the first arc plate 22, the second arc plate 23 drives the rotating shaft 33 and the rotating wheel 34 to move downward through the connecting frame 35, so that the transmission ratio between the frustum wheel 31 and the rotating wheel 34 becomes smaller, and the rotation angle of the two cylindrical tubes in the circumferential direction gradually becomes smaller, even if the moving speed of the welding head of the welding unit 131 on the weld path maintains a uniform rotation speed, it is ensured that the welding strength of the weld is uniform and consistent, thereby improving the welding effect.

[0072] Example 3: Based on Example 2, refer to Figure 1 and Figure 6-Figure 9As shown, it also includes: a reciprocating mechanism, which is arranged on the adjacent fixed frame 111, the first sliding rod 12 is limitedly slidably connected with the second arc plate 23, and the reciprocating mechanism is used to control the first sliding rod 12 to reciprocate, and the reciprocating mechanism includes: a fixed shell 4, which is fixed to the adjacent fixed frame 111 through a fixed block; a first conduit 41, which is fixed and connected to the fixed shell 4, and the first sliding rod 12 is located in the first conduit 41 and slides in a sealed manner; a second conduit 42, which is fixed and connected to the fixed shell 4; an electric push rod 43, which is fixed to the adjacent fixed frame 111, and its extension A first sliding plate 44 is fixedly connected to the contracted end, and the first sliding plate 44 slides in the second conduit 42. The first sliding plate 44 is provided with a sensor that is squeezed and matched with the second conduit 42; a limiting ring 45 is fixedly connected to the first sliding rod 12, and is provided with a sensor that is squeezed and matched with the second bracket 11. The sensor on the first sliding plate 44 and the sensor on the limiting ring 45 are both used to control the electric push rod 43 to switch the working mode; an adjusting component, the adjusting component is arranged in the fixed shell 4, and the adjusting component is used to adjust the first conduit 41 and the second conduit 42 to be in a connected state or a blocked state.

[0073] In the above scheme, under the tension of the tension spring connecting the first arc plate 22 and the second arc plate 23, the fourth sliding rod 21 is located at the weld of the two cylindrical tubes. When the first sliding rod 12 drives the second sliding rod 13 and the limiting ring 45 to move downward, when the limiting ring 45 fits the second arc plate 23, the second sliding rod 13 drives the welding head of the welding unit 131 to move to the cylindrical tube close to the lower side, that is, at this time, the welding head of the welding unit 131 moves to the lower limit. When the first sliding plate 44 moves upward to make the pressure sensor on it contact and squeeze the right side of the second conduit 42, the welding head of the welding unit 131 is just located at the lower edge of the vertical cylindrical tube. Figure 7 The state of the two cylindrical tubes (attached Figure 7 The weld track between the two cylindrical tubes is the large weld), and at this time, the position of the welding head on the welding unit 131 is the upper limit of the weld between the two cylindrical tubes.

[0074] During the welding operation of two cylindrical tubes in a large weld state, when the pressure sensor on the first sliding plate 44 is pressurized, the electric push rod 43 works to extend its upper telescopic end. When the pressure sensor on the limit ring 45 is pressurized, the electric push rod 43 is controlled to work to retract its upper telescopic end.

[0075] Reference Figure 8 and Fig. 9As shown, the adjustment component includes: a third sliding frame 6, which is slidably arranged in the fixed shell 4, and the third sliding frame 6 is provided with an air guide hole and an annular groove, and the arc groove on the third sliding frame 6 is used to connect the first conduit 41 and the second conduit 42; a screw rod 61, which is threadedly arranged on the fixed shell 4 and is rotatably connected to the third sliding frame 6; a third conduit 62, which is fixedly connected and connected to the fixed shell 4, and the air guide hole on the third sliding frame 6 is used to connect the first conduit 41 and the third conduit 62; a second sliding plate 63, which is slidably arranged in the third conduit 62, and the fixed shell 4, the first conduit 41, the second conduit 42 and the third conduit 62 are all filled with liquid; a limiting component, which is arranged on the second arc plate 23, and the limiting component is used to lock the first sliding rod 12 and the second arc plate 23.

[0076] In the above scheme, the screw rod 61 is rotated, and the screw rod 61 rotates to move the third sliding frame 6 in the fixed shell 4, and the air guide hole on the third sliding frame 6 is controlled to be connected with the first conduit 41 or the annular groove on the third sliding frame 6 is connected with the first conduit 41. The two rotations are two working modes of the device, one of which is used to weld the T-shaped connector that fits the weld seam after the two cylindrical tubes are combined (such as the attached Figure 1 The other is a T-shaped connector with a large weld at the weld after the two cylindrical tubes are combined (such as the attached Figure 7 The matching method of the two cylindrical tubes in the figure).

[0077] Reference Figure 8 and Fig.10 As shown, the limiting component includes: a telescopic push rod 7, which is installed in the second arc plate 23, and the first sliding rod 12 is provided with a blind hole, and the blind hole of the first sliding rod 12 is limitedly matched with the telescopic end of the telescopic push rod 7; a pipe 71, which is fixedly connected to the telescopic push rod 7 and communicated with the upper chamber of the telescopic push rod 7, and the other end of the pipe 71 is fixedly connected to and communicated with the fixed shell 4.

[0078] In the above scheme, when welding the T-shaped connector that fits the weld seam after the two cylindrical tubes are assembled, the telescopic end of the telescopic push rod 7 is inserted into the blind hole of the first sliding rod 12, so that the second curved plate 23 and the first sliding rod 12 are kept fixed, so that the second sliding rod 13 can move synchronously with the fourth sliding rod 21 through the first sliding rod 12, the second curved plate 23, the first curved plate 22 and the third sliding rod 2, thereby ensuring the movement stability of the welding head in the welding unit 131 on the second sliding rod 13, and facilitating the device to attach Figure 1 The weld trajectory of the two cylindrical tubes is welded stably and efficiently.

[0079] Working principle: Figure 1During the welding process of the weld seam track of the two cylindrical tubes, the operator rotates the screw 61 to control the movement of the third sliding frame 6, so that the air guide hole on the third sliding frame 6 connects the first conduit 41 and the third conduit 62, and at this time, the telescopic end of the telescopic push rod 7 is inserted into the blind hole of the first sliding rod 12, and at the same time, under the tension of the tension spring connecting the first curved plate 22 and the second curved plate 23, the fourth sliding rod 21 is close to the side wall of the cylindrical tube, and then the motor 3 is started through the control panel to rotate the two pre-connected cylindrical tubes, and the fourth sliding rod 21 will be in the vertical The fourth sliding rod 21 drives the first sliding rod 12 and the second sliding rod 13 to move together through the third sliding rod 2, the first arc plate 22 and the second arc plate 23. The movement of the second sliding rod 13 drives the welding head on the welding unit 131 to rotate together, so that the welding head on the welding unit 131 welds the weld trajectories of the two cylindrical tubes. The movement of the first sliding rod 12 causes the liquid between the first conduit 41 and the third conduit 62 to flow relatively, and the second sliding plate 63 moves accordingly in the third conduit 62.

[0080] In the attached Figure 7 During the welding process of the large welds of the two cylindrical tubes, the operator rotates the screw 61 to control the movement of the third sliding frame 6, so that the annular groove on the third sliding frame 6 connects the first conduit 41 with the second conduit 42, and the third sliding frame 6 moves through the pipeline 71 to extract the liquid in the upper chamber of the telescopic push rod 7, so that the telescopic end of the telescopic push rod 7 is pulled out from the blind hole of the first sliding rod 12, and then the electric push rod 43 and the motor 3 are started through the control panel, and the motor 3 rotates intermittently. When the motor 3 stops, the electric push rod 43 works to extend its telescopic end first, and the telescopic end of the electric push rod 43 drives the first sliding plate 44 to move to the left, and the first sliding plate 44 moves to push the liquid in the second conduit 42 into the first conduit 41, so that the first sliding rod 1 2 moves in the first guide tube 41, and when the first sliding rod 12 moves to make its upper limit ring 45 squeeze the second arc plate 23, the second sliding rod 13 drives the welding head of the welding unit 131 to move to the cylindrical tube close to the lower side, that is, at this time, the welding head of the welding unit 131 moves to the lower limit of the large weld between the two cylindrical tubes, and the pressure sensor on the limit ring 45 is pressed to control the telescopic end of the electric push rod 43 to drive the first sliding plate 44 to move rightward. When the first sliding plate 44 moves to make the pressure sensor on it contact and squeeze the right side of the second guide tube 42, the welding head of the welding unit 131 is just located at the lower edge of the vertical cylindrical tube, that is, the movement of the welding head on the welding unit 131 is located at the upper limit of the large weld between the two cylindrical tubes.

[0081] When the electric push rod 43 and the motor 3 repeat the above working process, the welding head on the welding unit 131 connects the large welds of the two cylindrical tubes by wire drawing to complete the welding process of the T-shaped connector, thereby improving the usability of the device and improving the welding stability of the device.

[0082] During the welding process of cylindrical tubes of different specifications, the operating frequency of the electric push rod 43 and the motor 3 can be adjusted according to the size of the weld to ensure the connection stability of the weld between the two cylindrical tubes and the connection strength after welding.
