[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-6 This utility model is a welding equipment for railway freight car bodies, including a base plate 1. A first lead screw 2 and a second lead screw 12 are rotatably connected to the base plate 1. A first bevel gear 3 is fixedly connected to the periphery of the first lead screw 2. A cross groove is opened in the second lead screw 12, and a cross clamp 10 is inserted into the cross groove. An L-shaped sleeve 9 is slidably connected to the base plate 1. The L-shaped sleeve 9 is rotatably engaged with the cross clamp 10. A second bevel gear 11 is fixedly connected to the end of the cross clamp 10. A first slider 4 and a second slider 13 are threadedly connected to the first lead screw 2 and the second lead screw 12, respectively. Both the first slider 4 and the second slider 13 are slidably engaged with the base plate 1. A welding torch 16 is fixedly connected to the surface of the base plate 1.

[0025] A motor 17 is fixedly connected to the side of the base plate 1, and the output end of the motor 17 is fixedly connected to the first lead screw 2.

[0026] The operation process of this embodiment is as follows: In use, two truck car panels 18 are placed on the surfaces of the first slider 4 and the second slider 13 corresponding to the first lead screw 2 and the second lead screw 12, respectively. After fixing, the first lead screw 2 is rotated by the motor 17. The rotation of the first lead screw 2 drives the first bevel gear 3 to rotate. The first bevel gear 3 is transmitted through the second bevel gear 11, thereby driving the second lead screw 12 to rotate synchronously. The two truck car panels 18 gradually move closer to each other until they are completely close. Then, the welding gun 16 is used to weld the two car panels 18. This allows the two car panels 18 to move closer to each other until they are tightly pressed together before the welding gun 16 welds them. This avoids gaps between the car panels 18 during welding, which would result in a lower flatness quality after welding.

[0027] Example 2

[0028] In actual use, such as Figure 1 As shown, although the two car body panels 18 can remain perpendicular and abut against each other after being connected, their contact position is fixed during welding. Otherwise, the car body will be either too short or too long after processing. That is, one car body panel 18 needs to be fixed in position before the other car body panel 18 moves toward and presses against the fixed panel 18. For this purpose, please refer to... Figure 2-5Based on the first specific embodiment, an interceptor plate 15 is fixedly connected to the side of the base plate 1. The interceptor plate 15 is located at the extension of the axis of the first lead screw 2. A crossbar 6 is fixedly connected to the bottom surface of the base plate 1. Two springs 7 are fixedly connected to the side of the crossbar 6. A push rail 8 is fixedly connected between the two springs 7. A round rod is fixedly connected to the first slider 4. A guide ball 5 is fixedly connected to the end of the round rod. The guide ball 5 slides with the push rail 8. The push rail 8 slides with the base plate 1. The push rail 8 is divided into a protruding part and a recessed part. An L-shaped sleeve 9 is fixedly connected to the recessed part of the push rail 8. The first bevel gear 3 and the second bevel gear 11 are arranged perpendicular to each other. The push rail 8 and the second bevel gear 11 are arranged parallel to each other.

[0029] The operation process of this embodiment is as follows: Two car plates 18 are placed on the U-shaped clamping plate 14 respectively. The motor 17 drives the first lead screw 2 to rotate. The rotation of the first lead screw 2 causes the first slider 4 to move relative to the U-shaped clamping plate 14. At this time, the main car plate 18 moves along the first lead screw 2. In this state... Figure 5 As shown, the guide ball 5 is located at the protruding part of the push rail 8, the spring 7 is in a compressed state, and the first bevel gear 3 and the second bevel gear 11 are not meshed. As the main car plate 18 gradually moves, when the guide ball 5 moves to the recessed part of the push rail 8, the spring 7 pushes the push rail 8 towards the position of the first lead screw 2. The movement of the push rail 8 drives the L-shaped sleeve 9, the cross lever 10, and the second bevel gear 11 to move. The second bevel gear 11 meshes with the first bevel gear 3. That is, the two car plates 18 do not move simultaneously, thus confirming the primary and secondary positions. After the main plate 18 is moved towards the interceptor plate 15, the main plate 18 moves until it contacts the interceptor plate 15 and the position of the main plate 18 is locked. At this time, although the first slider 4 is still moving towards the interceptor plate 15, the second bevel gear 11 meshes with the first bevel gear 3 after the position of the main plate 18 remains unchanged. The auxiliary plate 18 then moves towards the position of the main plate 18, so that the auxiliary plate 18 can be pressed against the side of the main plate 18 each time it is used, thereby avoiding the phenomenon of shortage or excess of the vehicle body after processing.

[0030] Example 3

[0031] To prevent gaps from appearing between the two panels 18 after they are connected during use, please refer to [link / reference needed]. Figure 1-4 Based on the first specific embodiment, a U-shaped card plate 14 is fixedly connected to the surface of both the first slider 4 and the second slider 13, and a number of sliding strips are provided inside the U-shaped card plate 14.

[0032] The operation process of this embodiment is as follows: two car plates 18 are placed stably in the U-shaped clamping plate 14. After the two car plates 18 meet, the U-shaped clamping plate 14 moves a short distance to make the two car plates 18 fit together fully. When the U-shaped clamping plate 14 moves, the car plates 18 slide on the slide bar, which can further improve the connection tightness between the two car plates 18, thereby improving the welding quality.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
