Description

Technical Field

[0001] The utility model relates to the technical field of drive shaft processing devices, and specifically refers to a welding device for processing automobile drive shafts. Background Technique

[0002] The automobile drive shaft is an important component in the automobile transmission system. It is mainly responsible for transmitting the power of the engine to the wheels to achieve the driving of the vehicle. The drive shaft is usually formed by connecting multiple shaft segments through welding and other methods, and its manufacturing quality and performance directly affect the power transmission efficiency and driving stability of the automobile.

[0003] In the production process of the drive shaft, welding is a key process. Different shaft parts are connected together through welding to form a complete drive shaft. However, traditional drive shaft welding devices have some obvious defects in practical applications.

[0004] In terms of the centering of shaft parts, traditional welding devices often have difficulty in achieving precise and stable centering operations. This may cause problems such as imbalance and vibration when the welded drive shaft rotates, affecting the transmission efficiency and service life. In terms of welding protection, the protection measures of traditional devices are usually not perfect. The strong light, high temperature and flying welding slag generated during the welding process are likely to cause harm to the operators, and may also affect the safety of the surrounding environment and equipment.

[0005] To sum up, in order to improve the welding quality and production efficiency of automobile drive shafts and ensure the safety of operators, it is necessary to develop a new type of automobile drive shaft welding device to solve the problems existing in the centering of shaft parts and welding protection of traditional welding devices.

A three-jaw chuck one 6 and a three-jaw chuck two 7 are respectively rotatably provided on the inner side surfaces of the first vertical plate 4 and the second vertical plate 5. A rotating wheel 8 is fixedly provided at one end of the rotating shaft of the three-jaw chuck two 7 that passes through the second vertical plate 5 and extends outside the second vertical plate 5. A driving mechanism for driving the second vertical plate 5 to slide is provided on the upper end surface of the base 1. A protective plate 9 is hingedly provided on the front surface of the first vertical plate 4.

[0031] Referring to the attached Figure 3 , the horizontal driving mechanism includes a first lead screw 10 rotatably provided below the bracket 2, and further includes a motor 11 fixedly provided below the bracket 2 for driving the first lead screw 10 to rotate.

[0033] Referring to the attached Figure 6 , the driving mechanism includes a groove 16 provided on the upper end surface of the base 1. A second lead screw 17 is rotatably provided inside the groove 16. A second slider 18 is threadedly connected to the second lead screw 17, and the second vertical plate 5 is fixedly provided on the second slider 18.

[0034] Referring to the attached Figure 1 , one side of the protective plate 9 away from the hinged end is magnetically attracted to the side surface of the second vertical plate 5 through a magnet, and a dark glass window 20 is provided on the protective plate 9.

[0035] Before the present utility model is used, an external power supply is first connected. The following is the detailed working process of the present utility model:

[0036] 1. Place one end of the drive shaft part to be welded on the three-jaw chuck 6 of the vertical plate 4. By rotating the adjusting nut on the three-jaw chuck 6, the three jaws move uniformly towards the center, thereby clamping the drive shaft part and fixing the part at the center of the chuck to ensure its stable position. Similarly, fix the second part on the three-jaw chuck 7. The height positions of the three-jaw chuck 6 and the three-jaw chuck 7 are fixed, and ensure that the centers are on the same horizontal line during assembly.

[0037] 2. Start the motor 19 in the drive mechanism. The motor 19 drives the lead screw 17 to rotate uniformly. The rotation of the lead screw 17 causes the slider 18 to slide smoothly along the groove 16, and then drives the vertical plate 5 to move towards the other end of the drive shaft part, promoting the two parts to complete docking and precise alignment.

[0038] 3. Start the motor 11. The motor 11 drives the lead screw 10 to rotate uniformly. The rotation of the lead screw 10 makes the slider 12 move horizontally along the guide rod 13. The operator precisely controls the rotation of the motor 11 according to the welding position of the drive shaft part, and moves the welding assembly 3 to directly above the welding position.

[0039] 4. Start the electric push rod 14. The piston end of the electric push rod 14 slowly extends or retracts, thereby adjusting the height of the welding head 15. The operator observes and measures to make the welding head 15 reach the optimal welding distance from the welding part.

[0040] 5. The operator closes the protective plate 9. The protective plate 9 is magnetically connected to the side of the vertical plate 5 through a magnet to form an effective protective barrier. The operator closely observes the welding situation through the dark glass window 20 on the protective plate 9, and then starts the welding equipment to start the welding operation. During the welding process, slowly rotate the runner 8 to weld the entire circumference of the joint of the two parts.

[0041] 6. After welding is completed, loosen the adjusting nuts on the three-jaw chuck 6 and the three-jaw chuck 7 in sequence to make the jaws release the drive shaft part. Carefully take out the welded drive shaft, check the welding quality, and if necessary, perform subsequent processing and trimming.

[0042] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present invention, design similar structural manners and embodiments to this technical solution without creativity, they should all fall within the protection scope of the present invention.
