Description

Technical Field

[0001] The invention relates to the technical field of intercooler welding, in particular to an intercooler positioning welding device and a welding method. Background Art

[0002] An intercooler is a device used to cool the compressed high-temperature and high-pressure air in a turbocharged engine. Its main function is to improve the engine's ventilation efficiency and performance. An intercooler is usually installed between the turbocharger and the engine's intake manifold. It reduces the temperature of the compressed air and increases the air density, thereby increasing the engine's power and torque. There is an interface at each end of the intercooler for connecting the compressed air circulation pipeline. In actual production, pipe fittings need to be welded at both ends of the intercooler for use.

[0003] When welding port pipes, it is generally necessary to use a clamp to fix the intercooler and the pipe to be welded. After the pipe welding is completed at one end of the intercooler, the staff needs to remove the clamp, change the position of the intercooler, and perform a second clamping to weld the pipe at the other end. The overall operation is designed with two clamping processes, which is relatively complicated. To avoid such problems, some staff members use the method of synchronous clamping at both ends, that is, clamping the welded pipes at both ends of the intercooler at the same time. Although the problem of secondary clamping can be avoided, when one port is welded, for the automated welding technology, the position of the welding robot needs to be transferred, or two welding robots need to be set up to work synchronously, which makes the overall cost of the equipment higher.

[0016] As a further solution of the present invention: the sliding sleeve member includes a transmission shaft rotatably mounted on the base and a sleeve rotatably mounted on the side of the transverse frame and slidably sleeved with the transmission shaft, the sleeve is connected to the rotating shaft of the rotating table through a bevel gear set and a first transmission belt, and the rotating shaft and the transmission shaft are connected through a second transmission belt;

The elastic pressure mechanism provides abutment force to ensure that the pipe fitting and the port of the intercooler maintain a tight and stable positioning state.

[0023] Secondly, whenever the transverse frame moves in the reverse direction and resets, the intermittent pipe-dropping mechanism can be triggered to automatically add pipes to the supporting seat.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0037] See also Figure 1-Figure 9 In an embodiment of the present invention, an intercooler positioning welding device includes a base 1 and a box 2 fixedly arranged on the side of the base 1 and having a conductive bottom, wherein the box 2 is used for stacking pipes welded to the intercooler port, and further includes:

[0038] A transverse frame 5 is movably mounted on the base 1 and connected to two sets of threaded drive mechanisms mounted on the base 1. The threaded drive mechanisms can drive the transverse frame 5 to move along the length direction of the base 1. A rotating table 15 is rotatably mounted on the transverse frame 5. The rotating table 15 is provided with a clamping mechanism for fixing the intercooler.

[0039] An intermittent pipe-dropping mechanism is provided on the box body 2. Whenever the intermittent pipe-dropping mechanism moves, it can release a pipe to the receiving seat 3 fixed on the base 1, and an elastic pressure mechanism is provided on the receiving seat 3;

[0040] The instantaneous ejection mechanism is installed on the transverse frame 5 and cooperates with the transmission mechanism installed on the base 1 and connected to the rotating shaft of the rotating table 15. When the transverse frame 5 moves toward the receiving seat 3, it can cause the pipe fittings on the receiving seat 3 to dock with the intercooler port and the elastic pressure mechanism to store elastic potential energy. When it moves away from the receiving seat 3, the transmission mechanism is triggered to drive the rotating table 15 to change direction, and the intermittent pipe dropping mechanism performs the material discharge action.

[0041] It should be supplemented that the threaded drive mechanism includes a one-way screw 26 rotatably mounted on the base 1 and a drive motor 25 mounted on the base 1, one end of the one-way screw 26 is connected to the output end of the drive motor 25, and a receiving block 27 is also slidably provided on the base 1, the receiving block 27 is located at the bottom of the transverse frame 5 and is fixed to the transverse frame 5, the one-way screw 26 passes through the receiving block 27, and the receiving block 27 is threadedly connected to the one-way screw 26;

[0042] During operation, the driving motor 25 drives the one-way screw 26 to rotate forward or reverse, so that the receiving block 27 can be threadedly matched with the one-way screw 26, and the receiving block 27 can drive the transverse frame 5 to move along the length direction of the base 1. On the one hand, it can prompt the intercooler to approach the pipe fittings located on the receiving seat 3, so that the port of the intercooler can be docked with the pipe fittings to complete the positioning, which is convenient for welding. On the other hand, after welding is completed, it can prompt the intercooler to drive the pipe fittings to be withdrawn from the receiving seat 3, and then the transmission mechanism drives the rotating table 15 to rotate half a circle, and the rotating table 15 drives the intercooler to change its direction, so as to realize the double-head welding processing of the intercooler.

[0043] Specifically, the rotating table 15 is arranged in a "U" shape, and the clamping mechanism is divided into two groups, including a bidirectional screw rod rotatably mounted on the rotating table 15 and two connecting blocks symmetrically arranged on the bidirectional screw rod and threadedly connected to the bidirectional screw rod, and two fasteners arranged in a "L" shape are respectively fixed on the two connecting blocks;

[0044] Before the welding work begins, the staff needs to fix the intercooler to be processed on the rotating table 15. Specifically, the intercooler is placed inside the rotating table 15, and the bidirectional screw on the rotating table 15 is rotated to make the two connecting blocks move closer to each other, and then the two opposite fasteners move closer to each other, and use their own "L"-shaped setting to clamp and fix the intercooler, ensuring the stability of the intercooler during the welding process, avoiding large errors in the welding work due to poor stability of the intercooler.

[0045] Please refer again Figure 5 and Fig. 9 The intermittent pipe dropping mechanism includes two first limit plates 9 and two second limit plates 10 which are slidably arranged on the box body 2 and arranged to support each other. The first limit plate 9 and the second limit plate 10 located on the same side are connected with a set of elastic driving structures. The first limit plate 9 is located above the second limit plate 10, and the second limit plate 10 is located at the bottom of the box body 2. The distance between the first limit plate 9 and the second limit plate 10 is equal to the diameter of the pipe. The elastic driving structure includes a guide rod 12 fixed to the side of the box body 2 through a protrusion block 11, a sliding block 13 slidably arranged on the guide rod 12, and a first column 1301 and a second column 1302 fixedly connected to the sliding block 13. The first limit plate 9 and the second limit plate 10 are respectively provided with a first through groove and a second through groove. The first column 1301 and the second column 1302 respectively penetrate the first through groove and the second through groove, and are respectively slidably connected to the first limit plate 9 and the second limit plate 10. The outer periphery of the guide rod 12 is also sleeved with a fourth column spring 14 whose two ends are respectively connected to the protrusion block 11 and the sliding block 13. The first through groove includes a first slide groove 901 and a second slide groove 902 connected to each other, the second through groove includes a third slide groove 1001 and a fourth slide groove 1002 connected to each other, the first slide groove 901 and the fourth slide groove 1002 are arranged straightly, the second slide groove 902 and the third slide groove 1001 are arranged inclined, and the sliding block 13 is also fixedly connected to a cross arm 28, and the end of the cross arm 28 away from the sliding block 13 abuts against the transverse frame 5.

[0046] Specifically, the end of the cross arm 28 away from the sliding block 13 is bent. Taking the state shown in the figure as an example, at this time, the transverse frame 5 is located at the end of the profile and away from the receiving seat 3, and the end of the cross arm 28 away from the sliding block 13 is in contact with the transverse frame 5, and the fourth column spring 14 is in a compressed state.

[0047] In the state described in the accompanying drawings, at this time, there is already a pipe on the receiving seat 3. After the transverse frame 5 drives the intercooler to move closer to the receiving seat 3, the transverse frame 5 will separate from the cross arm 28, the fourth column spring 14 rebounds, and the sliding block 13 slides away from the protruding block 11 on the guide rod 12. Accordingly, the first column 1301 passes through the first slide groove 901 and the second slide groove 902 in sequence, and the second column 1302 passes through the third slide groove 1001 and the fourth slide groove 1002 in sequence.

[0048] Specifically, when the first column 1301 is located in the first slide groove 901, the second column 1302 is located in the third slide groove 1001, and the second column 1302 slides with the second limit plate 10 through the third slide groove 1001, so that the second limit plate 10 slides toward the inside of the box 2. Then, the two second limit plates 10 on the box 2 are brought together to block the bottom of the box 2. Subsequently, the second column 1302 enters the fourth slide groove 1002 and moves along the fourth slide groove 1002. The two second limit plates 10 are moved together. The positioning plates 10 remain in a closed state, and the bottom of the box body 2 remains in a blocked state. At the same time, the first column 1301 enters the second slide groove 902 and moves along the second slide groove 902. The first column 1301 slides with the first limiting plate 9 through the second slide groove 902, causing the first limiting plate 9 to slide toward the outside of the box body 2. As a result, the two first limiting plates 9 move away from each other, so that the pipes stacked on the two first limiting plates 9 are released onto the two second limiting plates 10, and the two second limiting plates 10 receive the pipes.

[0049] On the contrary, after one end of the intercooler is welded, the transverse frame 5 drives the intercooler to move away from the receiving seat 3, so that the intercooler drives the welded pipe to be pulled out from the receiving seat 3, and in the latter part of the stroke, the transmission mechanism drives the rotating table 15 to rotate half a circle to exchange the position of the intercooler, and the transverse frame 5 will contact the cross arm 28 in the latter part of the stroke away from the receiving seat 3 and push the cross arm 28, and the cross arm 28 drives the sliding block 13 to slide on the guide rod 12 close to the protruding block 11, and accordingly, the first column 1301 passes through the second slide groove 902 and the first slide groove 901 in sequence, and the second column 1302 passes through the fourth slide groove 1002 and the third slide groove 1001 in sequence;

[0050] Specifically, when the first column 1301 passes through the second slide groove 902, the first limit plate 9 is prompted to move toward the inside of the box body 2, and the two first limit plates 9 are closed together to block the pipe fittings except the bottom layer. When the second column 1302 passes through the third slide groove 1001, the second limit plate 10 is prompted to slide toward the outside of the box body 2, and the two second limit plates 10 are opened, so that the pipe fittings of the bottom layer fall onto the receiving seat 3, realizing automatic unloading, and the amount of unloading each time can be accurately controlled.

[0051] Please refer again Figure 6 An arc-shaped receiving piece is fixedly provided on the receiving seat 3, and a cylindrical chamber is provided at the bottom of the receiving seat 3, the elastic pressure mechanism includes a first boss 401 slidably arranged in the cylindrical chamber and a cross bar 4 fixed to the first boss 401, a third cylindrical spring 8 is provided in the cylindrical chamber and is sleeved on the outer periphery of the cross bar 4, and the two ends of the third cylindrical spring 8 are respectively connected to the inner wall of the cylindrical chamber and the first boss 401, and a second boss 402 is fixed to the end of the cross bar 4 away from the first boss 401, and the second boss 402 is concentric with the arc-shaped receiving piece.

[0052] Whenever the two second limit plates 10 are opened, a pipe fitting located at the bottom layer of the box body 2 falls down and is received by the arc-shaped receiving plate. Subsequently, the intercooler moves toward the pipe fitting and abuts against the pipe fitting, and the second boss 402 is pushed by the pipe fitting. Accordingly, the cross bar 4 drives the first boss 401 to slide toward the outside of the cylindrical chamber, and the third cylindrical spring 8 is compressed. Therefore, under the elastic action of the third cylindrical spring 8, it can be ensured that during the welding process, the pipe fitting and the port of the intercooler are tightly fitted, thereby improving the positioning accuracy and welding effect.

[0053] Please refer again Figure 1 , Figure 2 , Figure 4 as well as Figure 6The transmission mechanism includes a rotating shaft 29 rotatably mounted on the base 1 and a sleeve 30 slidably sleeved on the rotating shaft 29. The rotating shaft 29 is connected to the rotating shaft of the rotating platform 15 through a sliding sleeve. The sleeve 30 is connected to a branch pipe 3001, and the branch pipe 3001 is fixed to the transverse frame 5 and cooperates with the instantaneous ejection mechanism. The outer wall of the rotating shaft 29 is provided with a connected spiral groove 2901 and a straight groove 2902. The line connecting the straight groove 2902 and the end of the spiral groove 2901 away from the straight groove 2902 is parallel to the central axis of the rotating shaft 29. The sliding sleeve includes a transmission shaft 16 rotatably mounted on the base 1 and a sleeve 17 rotatably mounted on the side of the transverse frame 5 and slidably sleeved with the transmission shaft 16. The sleeve 17 is connected to the rotating shaft of the rotating platform 15 through a bevel gear set 18 and a first transmission belt 19. The rotating shaft 29 and the transmission shaft 16 are connected through a second transmission belt 20.

[0054] In detail, a connecting shaft is rotatably installed on the side of the transverse frame 5, and the bevel gear set 18 includes a No. 1 bevel gear fixedly installed on the sleeve 17 and a No. 2 bevel gear fixedly installed on the connecting shaft. The No. 2 bevel gear is meshed with the No. 1 bevel gear, and the first transmission belt 19 is used to connect the rotating shaft of the rotating table 15 and the connecting shaft.

[0055] It should be emphasized that two strip-shaped protrusions are formed on the outer wall of the transmission shaft 16 , and two strip-shaped grooves adapted to the strip-shaped protrusions are provided on the inner wall of the sleeve 17 . The strip-shaped protrusions are arranged along the axial direction of the transmission shaft 16 .

[0056] Please refer again Figure 8 The instant ejection mechanism includes an assembly tube 21 disposed at the bottom of the transverse frame 5 and movable along the length direction of the transverse frame 5, and a movable rod 22 slidably fitted with the assembly tube 21. The movable rod 22 is fixed to a ring body 23 slidably disposed inside the assembly tube 21, and a first cylindrical spring 6 and a second cylindrical spring 7 are sleeved on the outer periphery of the movable rod 22. The first cylindrical spring 6 and the second cylindrical spring 7 have their head ends connected to the ring body 23, and their tail ends abut against the inner wall of the assembly tube 21. One end of the movable rod 22 is slidably connected to the branch pipe 3001 and is adapted to the spiral groove 2901 and the straight groove 2902, and the other end and the protruding column 2101 fixedly disposed on the assembly tube 21 are connected to a motion guide structure disposed on the base 1.

[0057] Please refer again Figure 6 and Figure 7The motion guiding structure includes a bottom plate 24 fixed on the base 1, and an inclined groove 2405 and a rectangular groove are provided on the bottom plate 24. The convex column 2101 extends into the inclined groove 2405 and is slidably connected to the bottom plate 24. The end of the movable rod 22 away from the branch pipe 3001 extends into the rectangular groove and is slidably connected to the bottom plate 24.

[0058] It should be added that a guide groove (not numbered in the figure) is also provided at the bottom of the transverse frame 5, and a slider (not numbered in the figure) is slidably engaged in the guide groove, and the assembly tube 21 is fixed on the slider to support the assembly tube 21 to move along the length direction of the transverse frame 5.

[0059] For the convenience of the following description, the rectangular groove is divided into a first groove section 2401, a second groove section 2402, a third groove section 2403 and a fourth groove section 2404 which are connected. Taking the state in the figure as an example, at this time, the end of the movable rod 22 away from the branch pipe 3001 (hereinafter referred to as the head end) is located at the intersection of the first groove section 2401 and the fourth groove section 2404, the boss 2101 is located at the end of the inclined groove 2405 close to the fourth groove section 2404, and the end of the movable rod 22 located in the branch pipe 3001 (hereinafter referred to as the tail end) has not yet extended into the spiral groove 2901;

[0060] During the movement of the transverse moving frame 5 toward the receiving seat 3, the head end of the movable rod 22 moves along the first slot section 2401, and the boss 2101 slides with the bottom plate 24 through the inclined slot 2405, and then the assembly tube 21 moves along the length direction of the transverse moving frame 5 toward the direction of the rotating shaft 29, and the first column spring 6 is compressed until the transverse moving frame 5 reaches the end of the stroke, and the head end of the movable rod 22 reaches the intersection of the first slot section 2401 and the second slot section 2402, so that the first column spring 6 rebounds, so that the head end of the movable rod 22 moves to the intersection of the second slot section 2402 and the third slot section 2403, and accordingly, the tail end of the movable rod 22 is inserted into the straight slot 2902;

[0061] After subsequent welding is completed, the transverse moving frame 5 moves in the opposite direction to reset. During this process, the tail end of the movable rod 22 moves along the straight groove 2902 and the spiral groove 2901 in sequence. When the tail end of the movable rod 22 moves along the straight groove 2902, the rotating shaft 29 does not rotate. This process is the process of completing the separation of the welded pipe fitting and the receiving seat 3, so as to prevent the rotating table 15 from rotating too early. When the tail end of the movable rod 22 moves along the spiral groove 2901, it will prompt the rotating shaft 29 to rotate one circle. Accordingly, the rotating shaft 29 is decelerated by the second transmission belt 20 to drive the transmission shaft 16 to rotate. The transmission shaft 16 drives the sleeve 17 to rotate through the strip protrusions, the strip protrusions and the strip grooves. The sleeve 17 drives the rotating table 15 to rotate 180° through the bevel gear set 18 and the first transmission belt 19, so as to realize the automatic transposition of the intercooler, that is, the end of the intercooler that has not yet been welded with the pipe fitting faces the receiving seat 3.

[0062] During the reverse movement and reset of the transverse frame 5, the head end of the movable rod 22 moves along the third groove section 2403, and the boss 2101 slides with the bottom plate 24 through the inclined groove 2405 again, so that the assembly cylinder 21 moves away from the rotating shaft 29 along the length direction of the transverse frame 5, and the second columnar spring 7 is compressed. After the transverse frame 5 completes the reset, the head end of the movable rod 22 reaches the intersection of the third groove section 2403 and the fourth groove section 2404, and the second columnar spring 7 rebounds, causing the head end of the movable rod 22 to reset to the intersection of the fourth groove section 2404 and the first groove section 2401. Accordingly, the tail end of the movable rod 22 is pulled out from the end of the spiral groove 2901 away from the straight groove 2902.

[0063] As another embodiment of the present invention, a method for positioning welding of an intercooler is also proposed, using the positioning welding device, comprising the following steps:

[0064] Step 1: Add the pipes to be welded into the box 2, and fix the intercooler on the rotating table 15 by the clamping mechanism;

[0065] Step 2: The threaded drive mechanism works to drive the transverse frame 5 to drive the intercooler toward the receiving seat 3 through the rotating platform 15, so that the port of the intercooler is connected to the pipe fitting located on the receiving seat 3;
