Description

Technical Field

[0001] This utility model relates to the field of positioning technology, and in particular to an auxiliary positioning device for laser spot welding. Background Technology

[0002] In modern manufacturing, laser spot welding is widely used in many fields such as electronics, automobiles, and aerospace due to its advantages such as high efficiency, high precision, and minimal thermal impact on materials.

[0003] When welding objects, most existing auxiliary positioners use clamps to hold and fix the objects. However, during the welding process, the object does not only need to be welded on one side. When welding other sides is required, the object needs to be unfixed and flipped over. The high temperature generated during welding can also affect the operator's operation, resulting in low welding efficiency. Therefore, this application proposes an auxiliary positioner for laser spot welding. Utility Model Content

[0004] The purpose of this invention is to address the problem of the cumbersome flipping of welding positioners in the prior art, and to propose an auxiliary positioner for laser spot welding.

[0005] The technical solution of this utility model is as follows: An auxiliary positioning device for laser spot welding, including a worktable, and further comprising:

[0006] A first track plate is slidably mounted on a workbench. The workbench has an installation groove, and a guide block is slidably mounted in the installation groove. The guide block is fixedly connected to the first track plate. Installation columns are symmetrically slidably mounted on the first track plate. An installation block is rotatably mounted on one side of each installation column, and a clamping plate is slidably mounted on one end of each installation block. A positive and negative threaded rod is rotatably mounted inside the first track plate. The positive and negative threaded rod is threadedly connected to the bottom of the installation column. A flipping mechanism for flipping the clamped object is provided on the installation column.

[0007] A cooling mechanism, which is mounted on the workbench, is used to rapidly cool the welded object.

[0008] Optionally, the flipping mechanism includes a limiting plate fixedly installed on one side of the mounting column. The limiting plate has multiple limiting holes arranged at equal intervals. A turntable is rotatably installed on one side of the limiting plate. The turntable is fixedly connected to the mounting block. A limiting post is slidably installed on the turntable. One end of the limiting post is located in the limiting hole. A handle is fixedly installed on one side of the turntable.

[0009] Optionally, the cooling mechanism includes a second track plate fixedly mounted on a workbench, a slider slidably mounted on the second track plate, the slider being hollow, a reciprocating screw rotatably mounted inside the second track plate, the reciprocating screw being threadedly connected to the slider, a blower fixedly mounted on one side of the second track plate, a connecting pipe fixedly mounted on one side of the blower, one end of the connecting pipe being fixedly connected to the slider, a first guide block fixedly mounted on one end of the slider, the first guide block being hollow, an installation pipe fixedly mounted on the bottom of the first guide block, a second guide block fixedly mounted on one end of the installation pipe, and multiple nozzles arranged at equal intervals fixedly mounted on the first and second guide blocks.

[0010] Optionally, a threaded rod is rotatably installed in the mounting slot, the threaded rod is threadedly connected to the guide block, and a first motor is fixedly installed on one side of the worktable, the output shaft of the first motor being fixedly connected to the threaded rod.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] This invention utilizes the forward and reverse threaded rods of a second motor to rotate, causing the clamping plates to move closer together and fix the object to be welded. By pulling the limiting post out of the limiting hole, the fixation of the turntable is removed, allowing the turntable to drive the clamping plates to rotate. This enables the object to be welded to be flipped without contact with it, improving operational convenience.

[0017] Furthermore, by starting the third motor and the blower, the third motor drives the reciprocating screw to rotate, causing the slider to move horizontally back and forth on the second track plate.

[0028] Example

[0029] like Figure 1 , Figure 2 As shown, the present invention proposes an auxiliary positioning device for laser spot welding, including a worktable 1 and a first track plate 2. The first track plate 2 is slidably mounted on the worktable 1. The worktable 1 has an installation groove 3, and a guide block 8 is slidably mounted in the installation groove 3. The guide block 8 is fixedly connected to the first track plate 2. Installation columns 9 are symmetrically slidably mounted on the first track plate 2. An installation block 20 is rotatably mounted on one side of the installation column 9. A clamping plate 10 is slidably mounted on one end of the installation block 20. A positive and negative threaded rod 26 is rotatably mounted in the first track plate 2. The positive and negative threaded rod 26 is threadedly connected to the bottom of the installation column 9. The installation column 9 is provided with a flipping mechanism for flipping the clamped object. Rotating the positive and negative threaded rod 26 causes the installation columns 9 to move closer to each other, and the clamping plate 10 on the installation column 9 clamps the object. Reversing the positive and negative threaded rod 26 cancels the fixation of the object.

[0030] like Figure 2 , Figure 3As shown, the flipping mechanism includes a limiting plate 22 fixedly installed on one side of the mounting column 9. The limiting plate 22 has multiple limiting holes 23 arranged at equal intervals. A turntable 24 is rotatably installed on one side of the limiting plate 22. The turntable 24 is fixedly connected to the mounting block 20. A limiting post 25 is slidably installed on the turntable 24. One end of the limiting post 25 is located in the limiting hole 23. A handle is fixedly installed on one side of the turntable 24. When it is necessary to flip the object, the limiting post 25 is pulled outward to pull one end of the limiting post 25 out of the limiting hole 23, thus releasing the fixation of the turntable 24. The turntable 24 is rotated, which drives the mounting block 20 to rotate. The mounting block 20 drives the clamping plate 10 to rotate, thereby flipping the object. After flipping, the limiting post 25 is inserted into the limiting hole 23 to fix the turntable 24, which facilitates subsequent welding.

[0031] like Figure 2 , Figure 3 As shown, a cooling mechanism is installed on the workbench 1 for rapid cooling of the welded object. The cooling mechanism includes a second track plate 12 fixedly installed on the workbench 1. A slider 14 is slidably installed on the second track plate 12. The slider 14 is hollow. A reciprocating screw 13 is rotatably installed inside the second track plate 12 and is threadedly connected to the slider 14. A blower 15 is fixedly installed on one side of the second track plate 12. A connecting pipe 16 is fixedly installed on one side of the blower 15. One end of the connecting pipe 16 is fixedly connected to the slider 14. A first guide block 17 is fixedly installed on one end of the slider 14. The first guide block 17 is hollow. An installation pipe 18 is fixedly installed at the bottom of the first guide block 17. A second guide block 19 is fixedly installed at one end of the mounting pipe 18. Multiple nozzles arranged at equal intervals are fixedly installed on the first guide block 17 and the second guide block 19. After welding is completed, the reciprocating screw 13 is rotated and the blower 15 is started. The reciprocating screw 13 drives the slider 14 to make horizontal reciprocating motion on the second track plate 12. The blower 15 delivers air from the connecting pipe 16 into the slider 14, and then the slider 14 delivers the first guide block 17. The air in the first guide block 17 is delivered from the mounting pipe 18 into the second guide block 19, so that the gas sprayed from the first guide block 17 and the second guide block 19 can fully cool the side of the welded object. With the rotation of the turntable 24, the object is cooled from all directions.

[0032] Furthermore, a threaded rod 6 is rotatably installed in the mounting groove 3, and the threaded rod 6 is threadedly connected to the guide block 8. A first motor 4 is fixedly installed on one side of the worktable 1, and the output shaft of the first motor 4 is fixedly connected to the threaded rod 6. When the first motor 4 is started, the output shaft of the first motor 4 drives the threaded rod 6 to rotate, thereby adjusting the position of the first track plate 2 to accommodate welding at different positions of the object. A second motor 5 is fixedly installed on one side of the first track plate 2, and the output shaft of the second motor 5 is fixedly connected to the positive and negative threaded rod 26. A third motor 11 is fixedly installed at one end of the second track plate 12, and the output shaft of the third motor 11 is fixedly connected to the reciprocating threaded rod 13. A spring 21 is fixedly installed at one end of the mounting block 20, and one end of the spring 21 is fixedly connected to the clamping plate 10. Slide grooves 7 are opened on both sides of the mounting groove 3, and the two ends of the guide block 8 are slidably connected to the slide grooves 7.

[0033] In this embodiment, the object to be welded is placed between the clamping plates 10. The second motor 5 is started, and the output shaft of the second motor 5 drives the forward and reverse threaded rods 26 to rotate. The forward and reverse threaded rods 26 drive the mounting posts 9 to move closer together, and the clamping plates 10 on the mounting posts 9 clamp the object. Reversing the forward and reverse threaded rods 26 releases the fixation of the object. When it is necessary to flip the object, the limiting post 25 is pulled outward, and one end of the limiting post 25 is pulled out of the limiting hole 23, releasing the fixation of the turntable 24. The turntable 24 is rotated, and the turntable 24 drives the mounting block 20 to rotate. The mounting block 20 drives the clamping plates 10 to rotate, thereby flipping the object. After flipping, the limiting post 25 is inserted into the limiting hole 23 to fix the turntable 24, making it easier to... For subsequent welding, the third motor 11 is started. The output shaft of the third motor 11 drives the reciprocating lead screw 13 to rotate, and the blower 15 is started. The reciprocating lead screw 13 drives the slider 14 to perform horizontal reciprocating motion on the second track plate 12. The blower 15 delivers air from the connecting pipe 16 into the slider 14, and then the slider 14 delivers the air to the first guide block 17. The air in the first guide block 17 is delivered from the mounting pipe 18 into the second guide block 19, so that the gas ejected from the first guide block 17 and the second guide block 19 can fully cool the side of the welded object. In conjunction with the rotating turntable 24, the object is cooled comprehensively. This allows the object to be flipped without contact during the welding process, and provides uniform heat dissipation from all directions, improving welding efficiency.

[0034] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
