Description

[0002] Most new energy vehicles use batteries to provide kinetic energy to the motor to drive the motor to run, thereby driving the vehicle to travel; therefore, the performance of the motor will directly affect the overall quality of the new energy vehicle. A major factor affecting the performance of the motor is the heat dissipation of the motor. In order to prevent the motor from overheating, the existing technology generally installs a spray pipe on the outside of the motor to spray liquid on the surface of the motor to achieve the purpose of cooling.

[0003] At present, when splicing motor spray pipes, the auxiliary pipes are welded to the main pipes by welding. During the welding operation of the existing spray pipes, the auxiliary pipes are manually held and aligned with the through holes of the main pipes before welding.

Although the auxiliary pipes can be welded to the main pipes in this way, the manual intensity during the welding process is relatively high and it also affects the work efficiency.

[0039] like Figure 1-11 The welding tool for the spray pipe of a motor of a new energy vehicle shown in the figure comprises a workbench 1 and a spray pipe blank 17. Support seats 3 are fixedly connected to both sides of the upper end of the workbench 1. A movable seat 4 is arranged on the upper ends of the two support seats 3. A U-shaped hole 12 is opened on the side end surface of the movable seat 4. A clamping mechanism 5 is arranged on the outer side of the two movable seats 4. A flipping mechanism 6 is arranged on the left side of the movable seat 4 on the left. The spray pipe blank 17 comprises a main pipeline 1701 and a secondary pipeline 1702. The main pipeline 1701 is located inside the U-shaped hole 12, and the secondary pipeline 1702 is welded to the lower end of the main pipeline 1701. A placement plate 7 is provided, and there are three placement plates 7, which are distributed between the two support seats 3. A positioning column 8 is fixedly connected to the upper end of the placement plate 7, and the positioning column 8 matches the auxiliary pipeline 1702; a supporting plate 11 is provided at the upper end of the workbench 1, and there are multiple supporting plates 11. The front and rear supporting plates 11 form a group and correspond to the positioning column 8; a lifting mechanism 2 is provided at the lower end of the workbench 1, and a transmission assembly 10 is provided on the lifting mechanism 2. A connecting assembly 9 is provided at the upper end of the workbench 1, and the lifting mechanism 2 is connected to the connecting assembly 9 through the transmission assembly 10; the transmission assembly 10 is connected to the supporting plate 11 through the connecting assembly 9.

[0040] Specifically, when welding the spray pipe of the new energy vehicle motor 602, first place the main pipe 1701 inside the U-shaped hole 12 of the movable seat 4, then the clamping mechanism 5 can clamp and fix the main pipe 1701, and then the auxiliary pipe 1702 is plugged into the positioning column 8. After the auxiliary pipe 1702 is plugged and installed, the lifting mechanism 2 can move down to drive the movable seat 4 to move down, and then drive the main pipe 1701 to move closer to the auxiliary pipe 1702. After the main pipe 1701 and the auxiliary pipe 1702 are tightly fitted, the auxiliary pipe 1702 is fixed, so as to facilitate the subsequent welding work, so that during the welding process, the spray pipe does not need to manually hold the auxiliary pipe 1702 and align it with the through hole of the main pipe 1701, thereby reducing the labor intensity of the workers. At the same time, since multiple auxiliary pipes 1702 are fixed at the same time, it is convenient When welding the other side of the spray pipe, the lifting mechanism 2 first performs the ascending operation to drive the auxiliary pipe 1702 away from the positioning column 8. After the auxiliary pipe 1702 is away from the positioning column 8 for a certain distance, the spray pipe blank 17 can be turned 180 degrees with the cooperation of the turning mechanism 6, so as to facilitate the welding of the other side of the spray pipe blank 17.

[0041] The lifting mechanism 2 includes a first hydraulic telescopic rod 201, a movable plate 202, a connecting rod 203, a connecting seat 204, a retaining ring 205, a movable ring 206, a first spring 207 and a first baffle 208. The lower end of the workbench 1 is fixedly connected with the first hydraulic telescopic rod 201, and the extended end of the first hydraulic telescopic rod 201 is fixedly connected with the movable plate 202. The four corners of the movable plate 202 are slidably connected with the connecting rod 203. The upper end of the connecting rod 203 passes through the workbench 1 and is slidably connected to the workbench 1. The upper end of the connecting rod 203 is fixedly connected with the connecting seat 204, and the connecting seat 204 is fixedly connected to the movable seat 4; the circumferential surface of the connecting rod 203 is fixedly connected with the retaining ring 205, and the retaining ring 205 is located at the upper end of the movable plate 202; the lower end of the connecting rod 203 is fixedly connected with the first baffle 208, and the first spring 207 is fixedly connected between the first baffle 208 and the movable plate 202. When working, the first hydraulic telescopic rod 201 works. At this time It can drive the moving plate 202 to move, so that the moving plate 202 no longer blocks the baffle ring 205, and then the moving seat 4 can be moved downward under the action of gravity. As the moving seat 4 moves downward, when the main pipe 1701 contacts the auxiliary pipe 1702, the moving seat 4 no longer moves, and then the moving plate 202 continues to move downward. After the moving plate 202 contacts the moving ring 206, the moving ring 206 will be squeezed to move downward, and then the first spring 207 can be compressed with the cooperation of the first baffle plate 208. The compressed first spring 207 can make the main pipe 1701 and the auxiliary pipe 1702 in close contact under the action of the reaction force, which is beneficial to the preliminary welding of the spray pipe blank 17. After the preliminary welding is completed, when the moving plate 202 is rising, it can drive the spray pipe blank 17 to rise, so that the auxiliary pipe 1702 is away from the positioning column 8, which is convenient for the later flipping work.

[0042] Limiting grooves 16 are provided on both the front and rear sides of the support seat 3, and the limiting rod 15 is slidably connected inside the limiting groove 16. The limiting rod 15 is fixedly connected to the moving seat 4. When working, by setting the limiting groove 16 and the limiting rod 15, the movement of the moving seat 4 can be limited with the cooperation of the limiting groove 16 and the limiting rod 15, so that the moving seat 4 can move smoothly.

[0043] The clamping mechanism 5 includes a second hydraulic telescopic rod 501, a connecting plate 502, a rotating cylinder 503 and a clamping plate 504. The second hydraulic telescopic rod 501 is fixedly connected to the outer sides of the two moving seats 4. The protruding end of the second hydraulic telescopic rod 501 is fixedly connected to the connecting plate 502. The connecting plate 502 is rotatably connected to the rotating cylinder 503 inside. The end of the rotating cylinder 503 close to the moving seat 4 is fixedly connected to the clamping plate 504. The hollow shape of the rotating cylinder 503 is a hexagonal prism. When working, the second hydraulic telescopic rod 501 contracts. At this time, with the cooperation of the connecting plate 502, the rotating cylinder 503 can be driven to move, and then the clamping plate 504 can be driven to approach the main pipe 1701. After the clamping plate 504 is tightly fitted with the main pipe 1701, the main pipe 1701 can be fixed.

[0044] The diameter of the clamping plate 504 is greater than the width of the U-shaped hole 12. During operation, since the diameter of the clamping plate 504 is greater than the width of the U-shaped hole 12, the clamping plate 504 can stably perform the clamping operation.

[0045] The flip mechanism 6 includes a support frame 601, a motor 602, a first bearing seat 603, a worm 604, a worm wheel 605, a second bearing seat 606 and a transmission shaft 607. The left side of the mobile seat 4 located on the left side is fixedly connected to the support frame 601, and the upper end of the support frame 601 is fixedly connected to the motor 602, the first bearing seat 603 and the second bearing seat 606. The worm 604 is rotatably connected inside the first bearing seat 603, and the worm 604 is fixedly connected to the output end of the motor 602. The upper end of the worm 604 is meshed with a worm wheel 605; the second bearing seat 606 is rotatably connected to the transmission shaft 607, and the transmission shaft 607 is fixedly connected to the worm wheel 605. The end close to the worm gear 605 is cylindrical, and the end of the transmission shaft 607 away from the worm gear 605 is hexagonal. The end of the transmission shaft 607 away from the worm gear 605 is located inside the rotating cylinder 503 and is slidably connected to the rotating cylinder 503. During operation, when it is necessary to weld the other side of the spray pipe, the motor 602 works. At this time, with the cooperation of the worm gear 605 and the worm 604, the transmission shaft 607 can be driven to rotate, and then the rotating cylinder 503 can be driven to rotate. With the rotation of the rotating cylinder 503, the preliminary welded spray pipe can be driven to rotate with the cooperation of the clamping plate 504, thereby facilitating the welding of the other side of the spray pipe and improving work efficiency.

[0046] The transmission assembly 10 includes a first connection block 1001, a linkage rod 1002, a second connection block 1003 and a sliding plate 1004. The first connection block 1001 is fixedly connected to both sides of the upper end of the movable plate 202. The linkage rod 1002 is rotatably connected inside the first connection block 1001. The end of the linkage rod 1002 away from the first connection block 1001 is rotatably connected to the second connection block 1003. The end of the second connection block 1003 away from the linkage rod 1002 is fixedly connected to the sliding plate 1004. When working, The movable plate 202 moves downward, and at this time, with the cooperation of the first connecting block 1001, the connecting rod 1002 and the second connecting block 1003, the sliding plate 1004 can be driven to move, thereby facilitating the support plate 11 to move closer to the auxiliary pipe 1702; when the flipping operation is required, as the movable plate 202 moves upward, when the movable plate 202 contacts the retaining ring 205, the support plate 11 no longer contacts the auxiliary pipe 1702, thereby facilitating the upward movement of the spray pipe blank 17, so that the auxiliary pipe 1702 is away from the positioning column 8.

[0047] A square hole 13 is provided on the upper end surface of the workbench 1, and a guide rod 14 is fixedly connected to the inside of the square hole 13; the sliding plate 1004 is located inside the square hole 13 and is slidably connected to the guide rod 14. When working, the square hole 13 is set to facilitate the movement of the sliding plate 1004 under the action of the square hole 13, and at the same time, under the action of the guide rod 14, the movement of the sliding plate 1004 can be limited, so that the sliding plate 1004 can stably move horizontally.

[0048] The connecting component 9 includes a moving rod 901, a second baffle 902 and a second spring 903. The moving rod 901 is slidably connected inside the sliding plate 1004. One end of the moving rod 901 is fixedly connected to the supporting plate 11, and the other end of the moving rod 901 is fixedly connected to the second baffle 902. The second spring 903 is fixedly connected between the second baffle 902 and the sliding plate 1004. The moving rod 901 is located inside the second spring 903. During operation, after the supporting plate 11 contacts the secondary pipe 1702, as the sliding plate 1004 continues to move, the moving rod 901 will be squeezed to slide inside the sliding plate 1004, and then the second spring 903 can be stretched with the cooperation of the second baffle 902. The stretched second spring 903 can enable the supporting plate 11 to stably support the secondary pipe 1702 under the action of the reaction force, thereby preventing the secondary pipe 1702 from tilting, which is beneficial for the cooperation between the secondary pipe 1702 and the main pipe 1701.

[0049] The supporting plates 11 are symmetrically distributed on both sides of the positioning column 8. The supporting plates 11 are in an arc shape. When working, the supporting plates 11 are in an arc shape, so the contact area between the supporting plates 11 and the auxiliary pipe 1702 can be increased, thereby improving the supporting effect.
