Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a welding tool for a rotor with an impeller. Background Art

[0002] With the continuous development of social economy and the increasing improvement of scientific and technological levels, my country's industry is also booming. The rotor, as a rotating body supported by bearings, is mostly the main rotating component of power machinery and working machinery, and plays an important role in industry.

[0003] In the prior art, there is a clamping device for a rotor with an impeller, which includes a clamping table and a positioning frame, wherein a plurality of positioning seats are provided and arranged at equal angles around the circumference. The plurality of positioning seats are fixedly mounted on the clamping table, and each positioning seat is provided with a fixing bolt, which is used to fix the corresponding blade to the corresponding positioning seat. When in use, the rotor is placed in the middle of the device table, and then each blade is placed on the corresponding positioning seat, and each blade is fixed to the corresponding positioning seat by a fixing bolt, so that the inner side of each blade is in contact with the rotor, and the clamping is completed.

[0004] Regarding the above-mentioned related technologies, since the blades themselves are tilted, it is difficult to ensure the consistency of the blade tilt angle and the blade outer diameter when positioning the blades by fixing bolts, so that relevant personnel need to spend a long time adjusting the position of each blade, which greatly reduces the efficiency of blade clamping and positioning, so it needs to be improved. Utility Model Content

[0005] In order to improve the efficiency of blade positioning and clamping, the present application provides a welding tool for a rotor with an impeller.

[0006] The present application provides a welding tool for a rotor with an impeller, which adopts the following technical solution:

[0007] A welding tool for a rotor with an impeller comprises a clamping table, on which a placement seat and a plurality of positioning seats are arranged. The placement seat is used to place the rotor, and the plurality of positioning seats are arranged in a circle with the placement seat as the center. Each of the positioning seats is provided with a contoured groove, which is adapted to the contour of a blade when tilted, and each of the contoured grooves is used for embedding a corresponding tilted blade. Each of the positioning seats is provided with an abutment mechanism, which abuts against the corresponding blade so that the blade is tightly attached to the inner wall of the corresponding contoured groove.

[0008] By adopting the above technical scheme, compared with the prior art, in which the blades are fixed only by fixing bolts, it is difficult to ensure the consistency of the blade inclination angle and the blade outer diameter. The present application makes the profiling groove adapt to the contour of the blade when tilted by opening a profiling groove and setting an abutment mechanism, so that the tilted blade can be placed in the profiling groove, and the blade is closely attached to the inner wall of the profiling groove under the abutment of the abutment mechanism, thereby realizing the positioning of the tilted blade and ensuring the consistency of the blade inclination angle and the blade outer diameter, so that relevant personnel do not need to adjust the position of the blade for a long time, which facilitates the positioning and clamping of the blade by relevant personnel, thereby improving the efficiency of blade positioning and clamping, and also improving the welding accuracy between the blade and the rotor.

[0009] Preferably, the abutment mechanism includes a mounting frame, a rotating frame, a driving assembly and an abutment frame, the mounting frame is mounted on the corresponding positioning seat, the rotating frame is rotatably connected to the mounting frame, the driving assembly is used to lock the rotating frame, and the abutment frame is arranged on the rotating frame and is used to abut against the surface of the blade.

[0010] By adopting the above technical solution and setting the abutment mechanism, relevant personnel can control the rotation of the rotating frame through the driving component, so that the rotating frame drives the corresponding abutment frame to move, so that the bottom end of the abutment frame gradually abuts against the top wall of the blade, so that the blade and the inner bottom wall of the contoured groove are closely attached to each other through the abutment, thereby fixing the blade, which effectively facilitates the operation of relevant personnel.

[0011] Preferably, the driving assembly includes a connecting frame and a driving frame, one end of the connecting frame is rotatably connected to an end of the mounting frame away from the rotating frame, one end of the driving frame is rotatably connected to the other end of the connecting frame, the other end of the driving frame is rotatably connected to the rotating frame, and the driving frame also extends a driving handle in a direction away from the rotating frame.

[0012] By adopting the above technical solution and the specific setting of the driving assembly, relevant personnel can hold and turn the driving handle to drive the driving frame to move, so that the driving frame drives the connecting frame and the rotating frame to rotate, thereby driving the rotating frame, while ensuring the stability of the rotating frame during rotation and the abutment effect of the abutment frame on the rotating frame on the blade surface.

[0013] Preferably, a locking groove is further provided on the mounting frame, and the locking groove is located between the connecting frame and the rotating frame. One end of the driving frame rotatably connected to the connecting frame is located in the locking groove and abuts against the inner wall of the locking groove.

[0014] By adopting the above technical solution and setting the locking groove, when the relevant personnel turns the rotating handle to the bottom of its own displacement path, one end of the driving frame and the connecting frame that are rotatably connected can move into the locking groove and abut against the inner wall of the locking groove, thereby hindering the probability of further displacement of the driving frame, thereby allowing the connecting frame to maintain its own position, so that the positions of the connecting frame, the driving frame and the rotating frame remain unchanged, thereby achieving locking of the abutment frame, so that the abutment frame maintains a locked state on the blade, ensuring the abutment effect of the abutment frame on the blade surface.

[0015] Preferably, the top end of each abutment frame passes upward from the bottom of the corresponding rotating frame, and each rotating frame is provided with a movable groove for the abutment frame to pass through. Each abutment frame is provided with two locking nuts, which are respectively located on the upper and lower sides of the corresponding rotating frame and are both threadedly connected to the abutment frame, and the locking nuts are abutted against the rotating frame.

[0016] By adopting the above-mentioned technical solution and setting the movable groove and the locking nut, relevant personnel can release the lock of the abutment frame by loosening the two locking nuts, so that the abutment frame can move in the movable groove, thereby changing the abutment position of the abutment frame on the blade by changing the position of the abutment frame and the rotating frame, adapting to different welding conditions, and increasing the practicality and scope of application of the present application.

[0017] Preferably, a plurality of support frames are provided on the clamping table, and the support frames are arranged in one-to-one correspondence with the positioning seats. The support frames are located between the placement seats and the corresponding positioning seats, and the top ends of the support frames are against the bottom ends of the corresponding blades.

[0018] By adopting the above technical solution, the support frame is set up so that the support frame can support the middle position of the blade, thereby reducing the probability of deformation and bending of the blade during the welding process, and thus effectively ensuring the quality of the rotor with blades after welding; at the same time, the existence of the support frame can also reduce the probability of accidental displacement of the blade, ensuring the subsequent welding effect of the blade and the rotor.

[0019] Preferably, each of the support frames is slidably connected to the clamping platform, and each of the support frames is fixed to the clamping platform by standard fasteners.

[0020] By adopting the above technical solution and setting the sliding connection between the support frame and the clamping table, relevant personnel can adjust the position of the support frame according to actual needs, thereby changing the supporting position of the support frame on the blade, thereby ensuring the supporting effect on the blade and the subsequent welding effect on the blade and the rotor.

[0021] Preferably, each of the positioning seats is slidably connected to the clamping platform, and each of the positioning seats is fixed to the clamping platform by standard fasteners.

[0022] By adopting the above-mentioned technical solution, the sliding connection between the positioning seat and the clamping table is set, so that relevant personnel can adjust the position of the positioning seat according to actual needs, so as to adapt to the change of blade position when the diameter of the rotor to be welded changes, thereby making the present application adaptable to bladed rotors of different sizes, thereby increasing the practicality and scope of application of the present application.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The configuration of the profiling groove and the abutment mechanism makes the profiling groove match the contour of the blade when tilted, so that the tilted blade can be placed in the profiling groove, and the blade is closely attached to the inner wall of the profiling groove under the abutment of the abutment mechanism, so as to achieve the positioning of the tilted blade, ensure the consistency of the blade tilt angle and the blade outer diameter, so that the relevant personnel do not need to adjust the position of the blade for a long time, and facilitate the positioning and clamping of the blade by the relevant personnel, thereby improving the efficiency of the positioning and clamping of the blade, and also improving the welding accuracy between the blade and the rotor;

[0025] 2. The setting of the abutment mechanism enables the relevant personnel to hold and rotate the driving handle to drive the driving frame to move, so that the driving frame drives the connecting frame and the rotating frame to rotate, and realizes the driving of the rotating frame, so that the bottom end of the abutment frame abuts against the blade, so that the blade and the inner bottom wall of the profiling groove are closely attached to each other through the abutment, thereby fixing the blade, and at the same time, it can also realize its own locking, ensuring the abutment effect of the abutment frame on the surface of the blade;

In the embodiment of the present application, the number of the positioning seats 3 on the clamping table 1 is set to seven, and the seven positioning seats 3 are arranged at equal angles along the circumference of the axis of the placement seat 2.

[0036] Reference Figure 2 The bottom end of each positioning seat 3 is embedded in the top wall of the clamping platform 1 and is slidably connected to the top wall of the clamping platform 1 to adjust the position of the positioning seat 3. The clamping platform 1 is also provided with a plurality of slots for the positioning seat 3 to slide, and the straight line where each positioning seat 3 slides intersects with the axis of the placement seat 2.

The fixing grooves 11 are all strip grooves to accommodate the sliding of the positioning seat 3. A standard fastener is provided in each fixing groove 11. In the embodiment of the present application, the standard fastener is a screw, and the top end of the screw passes through the fixing groove 11 and reaches the fixing groove 11 to achieve the fixing of the positioning seat 3 and the clamping platform 1.

[0038] Reference Figure 2 and Figure 4 Each positioning seat 3 has an inclined surface on the same side of the top, and each profiling groove 31 is provided on the side of the corresponding inclined surface close to the placement seat 2. Each abutting mechanism 4 is arranged on the top wall of the corresponding inclined surface, and each abutting frame 44 includes a mounting frame 41, a rotating frame 42, a driving assembly 43 and an abutting frame 44.
