Description

Technical Field

[0001] This utility model relates to the technical field of welding alternating platforms, specifically a dual-station alternating platform for a large-scale automatic welding room for castings. Background Technology

[0002] An alternating welding platform is a platform that allows castings to alternately change positions during the welding process. This type of platform is typically used to improve welding efficiency and precision, especially when welding both ends of a casting. It uses mechanical devices to alternate the orientation of the workpiece in the horizontal direction, thus facilitating welding operations for the operator.

[0003] A welding alternation platform typically includes components such as a servo motor, drive rod, reversing mechanism, and workpiece platform. When the workpiece is fixed on the workpiece platform, an external power source powers the servo motor, which drives the reversing mechanism to rotate the workpiece platform, thus achieving alternating reversal of the workpiece in the horizontal direction.

[0004] In the existing technology, the casting is fixed on the placement platform by the synergistic action of bolts and limit blocks, and then the casting is welded. This has the following disadvantages: the bolts and limit blocks cannot be adjusted according to different models of the casting, and the casting cannot be guaranteed to remain in the center position of the placement platform. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-station alternating platform for an automatic welding room for large castings, in order to solve the problems that bolts and limit blocks cannot be adjusted according to different casting models and that the castings cannot be kept in the center position of the placement platform.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a dual-station alternating platform for a large-scale automatic welding room for castings, comprising a load-bearing frame, the load-bearing frame being rotatably mounted above a mounting base, a drive motor being fixed to the inner wall of the mounting base, one end of the output shaft of the drive motor being fixed to the bottom surface of the load-bearing frame, a placement platform being fixed to both ends of the load-bearing frame, a cylinder being fixed to both the left and right sides of the placement platform, one end of the telescopic rod of the cylinder extending into the placement platform, a clamping plate being fixed to one end of the telescopic rod of the cylinder, two fixing plates being provided between the two clamping plates, two sleeves being movably hinged to the clamping plates, a connecting plate being inserted into the inner wall of the sleeves, one end of the connecting plate being connected to the sleeve by a screw, the other end of the connecting plate being movably hinged to the fixing plate, two limiting posts being fixed to the inner wall of the placement platform, and the clamping plate being slidably connected to the outer wall of the limiting posts.

[0007] Preferably, the top surface of the load-bearing frame is provided with a baffle plate, and two fixing frames are fixed on both the left and right sides of the baffle plate. The fixing frames are connected to the top surface of the load-bearing frame by screws.

[0008] Preferably, the top surface of the load-bearing frame is provided with a plurality of threaded grooves, and the top surface of the load-bearing frame is provided with a plurality of lifting lugs. The outer wall of the lifting lugs is provided with threads, and the threaded end of the lifting lugs is threadedly connected to the threaded grooves.

[0009] Preferably, the mounting base has a plurality of positioning holes, and fixing bolts are inserted into the inner wall of the positioning holes.

[0010] Preferably, a limiting ring is fixed to the bottom surface of the load-bearing frame, and a receiving groove is provided on the top surface of the mounting base, with the limiting ring inserted into the receiving groove.

[0011] Preferably, rubber pads are fixed to both the clamping plate and the fixing plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the cooperation of cylinders, clamping plates, fixing plates, sleeves, and connecting plates, castings of different models can be clamped and fixed in multiple directions, keeping the castings in the center position of the placement table, ensuring the accuracy of casting welding, preventing the welding position of the castings from shifting during welding vibration, thereby offsetting the torque or eccentric load during the welding process and reducing the risk of fixture deformation. The baffle plate can separate the working areas of two stations, effectively preventing sparks or debris from the castings during welding from splashing onto the other station, ensuring operational safety and equipment cleanliness.

[0014] 2. The lifting lugs are threaded onto the top surface of the load-bearing frame, facilitating easy disassembly and installation by operators. This allows for the handling and installation of the platform module using a crane or hook. Fixing bolts enable operators to secure the mounting base to the mounting surface, ensuring rigid fixation between the mounting base and the foundation or mounting surface, preventing displacement caused by welding vibration, and thus improving the stability of the mounting base. The combination of the limiting ring and the receiving groove effectively supports the radial load during the rotation of the load-bearing frame, distributing the load on the output shaft of the drive motor. This allows the drive motor to stably rotate the load-bearing frame for alternating work positions, thereby improving the working efficiency of the alternating platform. The soft material of the rubber pad effectively absorbs vibration and impact, protecting the casting surface from mechanical damage. Simultaneously, the elasticity of the rubber adapts to slight unevenness on the casting surface, ensuring clamping stability. Attached Figure Description

Detailed Implementation

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a dual-station alternating platform for a large-scale automatic welding room for castings includes a support frame 1, which is rotatably mounted above a mounting base 2. A drive motor 3 is fixed to the inner wall of the mounting base 2, and one end of the output shaft of the drive motor 3 is fixed to the bottom surface of the support frame 1. Placement platforms 4 are fixed to both ends of the support frame 1, and cylinders 5 are fixed to the left and right sides of the placement platforms 4. One end of the telescopic rod of the cylinder 5 extends into the placement platform 4, and a clamping plate 6 is fixed to one end of the telescopic rod of the cylinder 5. The two clamping plates 6 are positioned between each other. Two fixed plates 7 are provided, and two sleeves 8 are movably hinged on the clamping plate 6. A connecting plate 9 is inserted into the inner wall of the sleeve 8. One end of the connecting plate 9 is connected to the sleeve 8 by screws, and the other end of the connecting plate 9 is movably hinged to the fixed plate 7. Two limiting posts 10 are fixed to the inner wall of the placement platform 4. The clamping plate 6 is slidably connected to the outer wall of the limiting posts 10. A blocking plate 11 is provided on the top surface of the load-bearing frame 1. Two fixing frames 12 are fixed on both the left and right sides of the blocking plate 11. The fixing frames 12 are connected to the top surface of the load-bearing frame 1 by screws.

[0022] In use, when welding of castings is required, the castings can be hoisted onto the placement platform 4 on the right side of the workstation. Then, the two cylinders 5 are activated. The cylinders 5 drive the two clamping plates 6 to slide along the axis on the outer wall of the limiting column 10, achieving synchronous opposite movement. Under the continuous pressure of the cylinders 5, the clamping plates 6 push the fixing plate 7 to close towards the center through the linkage mechanism of the sleeve 8 and the connecting plate 9, until the clamping plates 6 and the fixing plate 7 make effective contact with the outer wall of the casting, so that the casting is kept in the center position of the placement platform 4. The length of the connecting plate 9 in the sleeve 8 can be adjusted by screws to adapt to the clamping requirements of different types of castings and achieve flexible positioning.

[0023] After the casting completes the automatic welding task, the drive motor 3 can be started. The drive motor 3 will drive the load-bearing frame 1 to rotate 180° to realize the alternation of the two workstations (the switching between the welding workstation and the loading and unloading workstation). This will start the cylinder 5. The cylinder 5 will move in the opposite direction, driving the clamping plate 6 and the fixing plate 7 to reset, releasing the clamping force on the casting. The operator will then lift the welded casting from the placement table 4 and simultaneously clamp a new casting at the empty workstation, forming a continuous production cycle.

[0024] The cylinder 5, clamping plate 6, fixing plate 7, sleeve 8, and connecting plate 9 work together to clamp and fix castings of different models from multiple angles, keeping the castings in the center of the placement table 4. This ensures the accuracy of casting welding and prevents the welding position from shifting during welding vibrations, thereby offsetting torque or eccentric loads during the welding process and reducing the risk of fixture deformation. The baffle plate 11 separates the working areas of the two stations, effectively preventing sparks or debris from the castings during welding from splashing onto the other station, ensuring operational safety and equipment cleanliness.

[0025] like Figures 1-4 As shown, the top surface of the load-bearing frame 1 has several threaded grooves 13, and the top surface of the load-bearing frame 1 has several lifting ears 14. The outer wall of the lifting ears 14 has threads, and the threaded end of the lifting ears 14 is threadedly connected to the threaded grooves 13. The mounting base 2 has several positioning holes 15, and the inner wall of the positioning holes 15 is fitted with fixing bolts 16. The bottom surface of the load-bearing frame 1 is fixed with a limit ring 17. The top surface of the mounting base 2 has a receiving groove 18, and the limit ring 17 is inserted into the receiving groove 18. The receiving groove 18 is filled with lubricating oil. Rubber pads 19 are fixed on both the clamping plate 6 and the fixing plate 7.

[0026] During use, the lifting lug 14 is threaded onto the top surface of the load-bearing frame 1, allowing operators to easily disassemble and install it. This enables operators to move and install the platform module using a crane or hook. The fixing bolt 16 allows operators to easily fix the mounting base 2 to the mounting surface, ensuring rigid fixation between the mounting base 2 and the foundation or mounting surface, preventing displacement caused by welding vibration, and thus improving the stability of the mounting base 2. The matching support of the limiting ring 17 and the receiving groove 18 effectively bears the radial load when the load-bearing frame 1 rotates, distributing the load on the output shaft of the drive motor 3. This allows the drive motor 3 to stably drive the load-bearing frame 1 to rotate for alternating work positions, thereby improving the working efficiency of the alternating platform. The soft material of the rubber pad 19 effectively absorbs vibration and impact, protecting the casting surface from mechanical damage. Simultaneously, the elasticity of the rubber adapts to slight unevenness on the casting surface, ensuring clamping stability.

[0027] 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.
