[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4 As shown, this utility model provides a positioning fixture for welding automotive drive shafts, including a bracket 1, a positioning mechanism 2 on the bracket 1, and auxiliary mechanisms 3 that cooperate with the positioning mechanism 2 on both sides of the top of the bracket 1. A welding mechanism that cooperates with the bracket 1 is provided at the top of the bracket 1, so that the automotive drive shaft to be welded can be welded. This is the prior art, and will not be described in detail here.

[0020] The positioning mechanism 2 includes a motor 21, which is fixedly mounted on one end of a bracket 1. A rotating rod 22 is fixedly connected to the output end of the motor 21. The rotating rod 22 is rotatably inserted into the bracket 1, and a rotating frame 23 is fixedly sleeved on the outer side of the rotating rod 22. A side plate 24 and a side plate 25 are integrally formed on the rotating frame 23. An electric push rod 26 is fixedly mounted on the side plate 25. The output end of the electric push rod 26 slides through the side plate 25 and a sleeve 27 is fixedly sleeved at its end. An L-shaped rod 28 is fixedly connected to the middle of one end of the sleeve 27. A through hole 211 is opened through the side plate 25, and the output end of the electric push rod 26 slides through the side plate 25. The through-hole 211 ensures the normal operation of the electric push rod 26. The end of the L-shaped rod 28 and the adjacent side plates 24 and 25 are all fixedly connected to the arc-shaped clamping frame 29. The arc-shaped clamping frame 29 is rotatably inserted with an array of rollers 210. The arc-shaped clamping frame 29 is rotatably inserted with an array of rotating shafts 212. The rollers 210 are rotatably sleeved in the middle of the rotating shafts 212. The arc-shaped clamping frame 29 is provided with an array of through holes 213 on both sides. The rotating shafts 212 are rotatably inserted in the adjacent through holes 213. The cooperation between the through holes 213 and the rotating shafts 212 ensures the stable rotation of the rollers 210.

[0021] By adopting the above technical solution, during use, the vehicle drive shaft to be welded is placed in the adjacent arc-shaped clamping frames 29 near the rotating frame 23, and the corresponding two electric push rods 26 are activated. This drives the corresponding sleeve 27 to move closer to the rotating frame 23, which in turn drives the corresponding L-shaped rod 28 to move closer to the rotating frame 23, and further drives the other corresponding arc-shaped clamping frame 29 to move closer to the corresponding vehicle drive shaft to be welded. When the rollers 210 on the two adjacent arc-shaped clamping frames 29 are in close contact with the outer wall of the corresponding vehicle drive shaft to be welded, the electric push rods 26 are turned off, and then the motor 21 is started. This drives the rotating rod 22 to rotate 90 degrees, which in turn drives the rotating frame 23 to rotate 90 degrees, and further drives the clamped vehicle drive shaft to rotate 90 degrees.

[0022] The auxiliary mechanism 3 includes an electric push rod 31, which is fixedly installed on both top sides of the bracket 1. The output end of the electric push rod 31 slides through the bracket 1 and is fixedly connected to a horizontal plate 32 at its end. Sliding holes 11 are provided on both sides of the top of the bracket 1, and the output end of the electric push rod 31 slides through the sliding holes 11. The sliding holes 11 ensure the normal operation of the electric push rod 31. Guide rods 38 are fixedly installed at the four corners of the bottom of the horizontal plate 32, and the guide rods 38 slide through the bracket 1. The upper sides of the bracket 1... The horizontal plate 32 is provided with symmetrically distributed guide holes 12 through each end, and the guide rod 38 is slidably inserted into the guide hole 12. The cooperation between the guide rod 38 and the guide hole 12 plays a limiting and guiding role in the movement adjustment of the horizontal plate 32. The top of the horizontal plate 32 is fixedly installed with an electric cylinder body 33, and an electric cylinder slider 34 is slidably provided on the electric cylinder body 33. The top of the electric cylinder slider 34 is fixedly connected with an L-shaped plate 35, and a second motor 36 is fixedly installed on the L-shaped plate 35. The output end of the second motor 36 rotates through the L-shaped plate 35 and a pin 37 is fixedly installed at its end.

[0023] By adopting the above technical solution, in use, the electric push rod 31 is activated, which drives the horizontal plate 32 to adjust its height, thereby driving the L-shaped plate 35 and the ejector pin 37 to adjust their height. When the axis of the ejector pin 37 moves to the same height as the axis of the automotive drive shaft to be welded, the electric push rod 31 is closed. Then, the electric cylinder body 33 is activated, which drives the electric cylinder slider 34 to move in opposite directions, thereby driving the ejector pin 37 to move in opposite directions. When the opposite ends of the ejector pin 37 are in close contact with the two ends of the automotive drive shaft to be welded, the electric cylinder body 33 is closed. Subsequently, the welding mechanism and the second motor 36 are activated, which drives the ejector pin 37 to rotate, thereby driving the corresponding automotive drive shaft to be welded to rotate and cooperating with the welding mechanism to perform welding processing.

[0024] Working principle: In use, the vehicle drive shaft to be welded is placed in the adjacent arc-shaped clamping frames 29 near the rotating frame 23 in sequence, and the corresponding two electric push rods 26 are activated. This drives the corresponding sleeve 27 to move closer to the rotating frame 23, which in turn drives the corresponding L-shaped rod 28 to move closer to the rotating frame 23. Furthermore, it drives the other corresponding arc-shaped clamping frame 29 to move closer to the corresponding vehicle drive shaft to be welded. When the rollers 210 on the two adjacent arc-shaped clamping frames 29 are in close contact with the outer wall of the corresponding vehicle drive shaft to be welded, the electric push rods 26 are turned off. Then the motor 21 will be started, which drives the rotating rod 22 to rotate 90 degrees, which in turn drives the rotating frame 23 to rotate 90 degrees, and further drives the clamped vehicle drive shaft to rotate 90 degrees.

[0025] At this time, the electric push rod 31 is activated, which drives the horizontal plate 32 to adjust its height, thereby driving the L-shaped plate 35 and the ejector pin 37 to adjust their height. When the axis of the ejector pin 37 moves to the same height as the axis of the automotive drive shaft to be welded, the electric push rod 31 is closed. Then, the electric cylinder body 33 is activated, which drives the electric cylinder slider 34 to move in opposite directions, thereby driving the ejector pin 37 to move in opposite directions. When the opposite ends of the ejector pin 37 are in close contact with the two ends of the automotive drive shaft to be welded, the electric cylinder body 33 is closed. Then, the welding mechanism and the second motor 36 are activated, which drives the ejector pin 37 to rotate, thereby driving the corresponding automotive drive shaft to be welded to rotate and perform welding in conjunction with the use of the welding mechanism. During this period, the user can follow the above steps to fix the next automotive drive shaft to be welded. In subsequent use, the user can easily remove the welded automotive drive shaft for loading and fixing.
