Description

Technical Field

[0001] This utility model relates to the field of welding frame technology, specifically to an adjustable angle wheel blade welding frame. Background Technology

[0002] In the welding process of turbine blades, the welding frame plays a crucial supporting and positioning role. Most existing welding frames are fixed structures, which are severely lacking in flexibility when facing turbine blades of different specifications and with different angle requirements. Workers often need to spend a lot of time manually adjusting or replacing the welding frame, resulting in low production efficiency. Moreover, due to the inability to accurately adapt to the blade angle, quality problems such as uneven welds and incomplete welds are prone to occur during the welding process. Such blades are more likely to develop fatigue cracks and surface wear during use, which seriously affects their service life.

[0003] To address the aforementioned issues, innovative design based on existing equipment is urgently needed. Therefore, we proposed an adjustable-angle rotor blade welding frame that can effectively solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable angle rotor blade welding frame to solve the problems mentioned in the background art. Existing welding frames are mostly fixed structures, which are severely lacking in flexibility when facing rotor blades of different specifications and with different angle requirements. Workers often need to spend a lot of time manually adjusting or replacing the welding frame, resulting in low production efficiency. Moreover, due to the inability to accurately adapt to the blade angle, quality problems such as uneven welds and incomplete welds are prone to occur during the welding process. Such blades are more prone to fatigue cracks and surface wear during use, which seriously affects their service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-angle rotary blade welding frame, comprising a load-bearing frame, with bases welded to the four corners of the bottom end of the load-bearing frame, and pulleys for moving the overall welding frame installed at the bottom of the bases; a clamping assembly is provided on the top of the load-bearing frame, and the clamping assembly includes rotating seats movably disposed on the top of both sides of the load-bearing frame, a rotating screw shaft rotatably disposed on the inner side of the rotating seat, and manual rotating wheels fixedly connected to both ends of the rotating screw shaft, and a movable clamp threadedly connected to the outer side of the rotating screw shaft, and the movable clamp having a double-clamping point structure; an angle adjustment assembly is also provided on the top of the load-bearing frame, and the angle adjustment assembly includes a motor fixedly installed on the outer wall of the left side of the load-bearing frame, and the output shaft of the motor is connected to the rotating seat on this side through a rod body; a connecting rod is rotatably connected to the inner side of the middle of the load-bearing frame, and transmission wheels are fixedly connected to the outer sides of the two rotating seats through the rod body and the two sides of the connecting rod, and a transmission belt is driven by the outer sides of the two transmission wheels on the same side.

[0006] Preferably, the load-bearing frame is made of high-temperature resistant steel structure material, and the middle part is welded to form an "H"-shaped double-layer structure to enhance structural stability.

[0007] Preferably, the top of the pulley is fixedly connected to a connecting bolt via a mounting base, and the bottom end of the base is provided with a screw hole that matches the connecting bolt, so as to achieve a stable threaded installation of the pulley on the base.

[0008] Preferably, each pulley is equipped with a brake on one side, and the brake rotates around the wheel axle and engages with the wheel to achieve the effect of stopping the pulley in real time and prevent the welding frame from moving randomly during use.

[0009] Preferably, the inner wall of the load-bearing frame is provided with a receiving groove, and the rotating seat is rotatably disposed inside the receiving groove to achieve rotational limitation of the rotating seat.

[0010] Preferably, the movable clamp has an "F" shaped structure, that is, it has a clamping point extending from the side at its upper end, and the surface of the clamping point is formed with clamping teeth. This structure can increase the friction between the movable clamp and the blade, thereby improving the clamping stability.

[0011] Preferably, the bottom end of the movable clamp is formed with a slider, and the inner wall of the bottom end of the rotating seat is provided with a groove that matches the slider. By limiting the sliding of the slider and the groove, the movement of the two movable clamps can be limited in the horizontal direction to achieve stable horizontal clamping.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This adjustable angle rotary blade welding frame, by setting clamping components and angle adjustment components, has significant advantages in this adjustable structural design. It can quickly adapt to rotary blades of different specifications and angle requirements. By rotating the manual rotary wheel and starting the motor, the angle setting can be completed in 5-10 minutes, which enhances the flexibility of use and greatly improves production efficiency. Moreover, the precise angle adjustment can ensure the best blade welding position, uniform and firm weld, prevent false welding, and improve the service life of the blade. The specific contents are as follows: (1) By setting clamping components, when in use, just rotate the manual rotary wheels on both sides to drive the rotating screw shaft to rotate synchronously. The two sets of movable clamps will move closer to clamp the rotary blades between them. This adjustable structural design has significant advantages. It can quickly adapt to rotary blades of different specifications and angle requirements. Workers can complete the angle setting in 5-10 minutes by rotating the manual rotary wheel, which enhances the flexibility of use and greatly improves production efficiency.

[0013] (2) By setting an angle adjustment component, when in use, the motor is started to drive the left rotating seat to rotate. At the same time, the right rotating seat is driven to rotate through the sequential transmission of the left transmission wheel, the left transmission belt, the connecting rod, the right transmission wheel, and the right transmission belt. In this way, the clamping parts and blades installed on both rotating seats also rotate. This precise angle adjustment can ensure the best welding position of the blade, the uniform and firm weld, and prevent false welding. This avoids the fatigue cracks and surface wear that are easy to occur when the blade is in use, and improves the service life of the blade.

[0014] (3) By connecting the bolts on the pulleys and the screw holes on the base, the pulleys can be securely threaded onto the base. Furthermore, by installing brakes on one side of each pulley, the pulleys can be stopped in real time, preventing the welding frame from moving arbitrarily during use.

[0015] (4) The friction between the movable clamp and the blade can be effectively increased by the movable clamp with the “F” structure and the clamping teeth formed on the clamping point surface, thereby improving the clamping stability. At the same time, the movement of the two movable clamps can be limited in the horizontal direction by the limiting sliding of the slider and the groove, so as to achieve stable horizontal clamping.

[0023] 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.

[0024] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: an adjustable angle rotary blade welding frame, including a load-bearing frame 1. The load-bearing frame 1 is made of high-temperature resistant steel structure material, and the middle part is welded to form an "H"-shaped double-layer structure to enhance structural stability. The bottom corners of the load-bearing frame 1 are welded with bases 2, and the bottom of the bases 2 are equipped with pulleys 3 for moving the overall welding frame. The top of the pulleys 3 is fixedly connected with connecting bolts 16 through mounting seats, and the bottom of the bases 2 is provided with screw holes that are compatible with the connecting bolts 16. By using the connection bolts 16 and the screw holes, the pulleys 3 can be stably threadedly installed on the bases 2. Each pulley 3 is equipped with a brake 17 on one side, and the brake 17 rotates around the wheel axle and engages with the wheel to achieve the effect of stopping the pulleys 3 in real time and prevent the welding frame from moving randomly during use.

[0025] Furthermore, a clamping assembly is provided on the top of the load-bearing frame 1, and the clamping assembly includes a rotating seat 5 movably disposed on the top of both sides of the load-bearing frame 1. A receiving groove 4 is provided on the inner side wall of the load-bearing frame 1, and the rotating seat 5 is rotatably disposed on the inner side of the receiving groove 4 to realize the rotation limit of the rotating seat 5. A rotating screw 7 is rotatably disposed on the inner side of the rotating seat 5, and a manual rotating wheel 8 is fixedly connected to both ends of the rotating screw 7. A movable clamp 9 is threadedly connected to the outer side of the rotating screw 7, and the movable clamp 9 has a double clamping point structure.

[0026] In use, the blade to be welded is placed between two sets of movable clamps 9. Then, simply rotate the manual rotating wheels 8 on both sides. The manual rotating wheels 8 drive the rotating screw 7 to rotate synchronously, and the two sets of movable clamps 9 will move closer to clamp the blade. This adjustable structural design has significant advantages. It can quickly adapt to blades of different specifications and angle requirements. Workers can complete the angle setting in 5-10 minutes by rotating and adjusting the manual rotating wheels 8, which enhances the flexibility of use and greatly improves production efficiency. Precise angle adjustment can ensure the optimal welding position of the blade, and the weld is uniform and firm, preventing false welding. This avoids fatigue cracks and surface wear that are easy to occur during blade use, thus extending the service life of the blade.

[0027] Among them, the movable clamp 9 has an "F" shaped structure, that is, it has a clamping point extending from the side at the upper end, and the clamping point surface is formed with clamping teeth 10. This structure can increase the friction between the movable clamp 9 and the blade, thereby improving the clamping stability. The bottom end of the movable clamp 9 is formed with a slider 11, and the inner wall of the bottom end of the rotating seat 5 is provided with a sliding groove 12 that matches the slider 11. By limiting the sliding of the slider 11 and the sliding groove 12, the movement of the two movable clamps 9 can be limited in the horizontal direction to achieve stable horizontal clamping.

[0028] Example 2: Based on Example 1, the top of the load-bearing frame 1 is also provided with an angle adjustment component, and the angle adjustment component includes a motor 6 fixedly installed on the outer wall of the left side of the load-bearing frame 1, and the output shaft of the motor 6 is connected to the rotating seat 5 on this side through a rod. A connecting rod 15 is rotatably connected to the inner side of the middle part of the load-bearing frame 1, and transmission wheels 13 are fixedly connected to the outer sides of the two rotating seats 5 through the rod and both sides of the connecting rod 15. The outer sides of the two transmission wheels 13 on the same side are jointly driven by a transmission belt 14.

[0029] In use, the starter motor 6 drives the left rotating seat 5 to rotate. At the same time, through the transmission wheel 13 and transmission belt 14 on the left, the connecting rod 15 can be driven synchronously. The connecting rod 15 continues to drive the right rotating seat 5 to rotate through the transmission wheel 13 and transmission belt 14 on the right. In this way, the rotating seats 5 on both sides rotate synchronously. The clamping parts installed on the rotating seats 5 and the blades they clamp also rotate accordingly, so as to adjust the angle of the blades and achieve flexible welding.
