Description

Technical Field

[0001] This invention relates to the field of machining tooling technology for output end caps, specifically to a high-speed stage output end cap tooling for intelligent fans. Background Technology

[0002] As a key piece of equipment in the new energy field, the high-speed output end cap of the intelligent wind turbine is one of the core components that ensures the stable and efficient operation of the wind turbine. The processing accuracy of this end cap directly affects the assembly accuracy and operating performance of the wind turbine.

[0003] Reference Figure 1-4 As can be seen from the content, in the prior art, there is an intelligent fan output end cover 3, which is mainly composed of an end cover body 31, a sealing and fitting structure 32, and a reinforcing structure 33 integrally formed: wherein, the sealing and fitting structure 32 is placed on the bottom surface of the end cover body 31, and is used to ensure the sealing performance of the fan inside after the end cover is assembled; the reinforcing structure 33 is placed on the top surface of the end cover body 31 to enhance the overall structural strength of the end cover, so that it can adapt to the complex mechanical environment of the intelligent fan during high-speed operation;

[0004] To meet the processing and positioning requirements of the output end cap 3, the existing conventional processing fixtures include a substrate 1, a processing table 2 located on the top surface of the substrate 1, and three sets of positioning fixtures arranged in a triangular shape around the outer periphery of the processing table 2. Specifically, the positioning fixtures consist of a clamping plate 4, a rotating shaft 5, and a positioning screw 6. The rotating shaft 5 is rotatably connected through a bearing embedded in the top surface of the substrate 1, and the top end of the rotating shaft 5 is fixedly connected through one end of the clamping plate 4, so that the clamping plate 4 can rotate around the rotating shaft 5 to facilitate the placement and removal of the output end cap 3. At the same time, the positioning screw 6 passes through the middle of the clamping plate 4 in a vertical direction, and the bottom end of the positioning screw 6 is threaded with a nut 7 fixed to the top surface of the substrate 1. During operation, by tightening the positioning screw 6, the clamping plate 4 can be used to press and position the output end cap 3 placed on the processing table 2 from top to bottom.

[0005] However, the three sets of positioning fixtures can only exert a "top-down" pressing and limiting effect on the output end cover 3 from multiple directions. But in actual grinding, cutting and other processing operations, when the processing tool comes into contact with the inner wall of the output end cover 3, it will generate a lateral force on the end cover. Since the existing positioning fixtures lack an effective "lateral limiting structure", the output end cover 3 is very likely to deflect laterally relative to the processing table 2 when subjected to this lateral force. This will not only greatly reduce the processing accuracy and seriously affect the processing quality of the end cover, but also lead to a decrease in the stability of the fit between the processing tool and the end cover, increase the safety hazards in the processing process, and make it difficult to meet the requirements of "high precision and high stability" processing for the high-speed output end cover of the intelligent fan. Summary of the Invention

[0006] To solve the above-mentioned technical problems, a tooling for the output end cover of a high-speed stage of an intelligent fan is provided, which solves the problems existing in the background technology.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a tooling for the high-speed output end cover of an intelligent fan, which mainly consists of a base plate, a processing table assembled on the top surface of the base plate, and three sets of positioning fixtures arranged in a triangular shape around the outer periphery of the processing table.

[0008] The positioning fixture includes a clamping block that can be deflected above the processing table. The fixture is characterized in that it further includes a lateral limiting part, which is arranged in two symmetrical sets.

[0009] The lateral limiting part includes a convex positioning seat that is detachably mounted to the top surface of the substrate by bolts. The top of the positioning seat is provided with a deflectable movable clamp. The movable clamp has an L-shaped structure and one end is provided with a telescopically adjustable extrusion screw.

[0010] Preferably, the lateral limiting part includes a convex positioning seat that is detachably mounted on the top surface of the substrate. The top end of the positioning seat is rotatably connected to a support column. The column body is fixedly fitted with an L-shaped movable clamp. One end of the movable clamp is vertically fixed with a compression screw.

[0011] Preferably, a support column is fixedly inserted through the inner wall at the corner of the movable clamp, and the bottom end of the support column is rotatably connected to the top surface of the positioning seat through a bearing.

[0012] Preferably, the other end of the movable clamp has a notch, a locking screw is inserted into the notch, a metal washer is provided between the nut of the locking screw and the movable clamp, and the top of the positioning seat has a screw hole that matches the locking screw.

[0013] Preferably, the inner wall of the movable clamp has a transversely penetrating contraction channel adapted to the extrusion screw, the rod end of the extrusion screw slides into the contraction channel, and a nut is threaded on its rod body and fixed to the side wall of the movable clamp.

[0014] Preferably, an adjusting pressure block is inserted through one end of the clamping block, and a push-pull member for raising and lowering the adjusting pressure block is provided on the top of the clamping block.

[0015] Preferably, the push-pull component includes a limiting piece fixed to the top surface of the clamping block in an inverted L shape, the side wall of the adjusting block slides in contact with the vertical inner wall of the limiting piece, the top end of the limiting piece is provided with a push-pull screw that is rotatably connected to the top end of the adjusting block, and the push-pull screw is threaded with a nut that is fixed to the top surface of the limiting piece.

[0016] Compared with the prior art, the advantages of the present invention are as follows: by setting the lateral limiting part, the movable clamp can be deflected around the support column first, so that the cap end of the extrusion screw abuts against the side wall of the reinforcing structure, and then the locking screw is tightened. The position of the movable clamp is fixed by the buffer of the metal washer and the thread engagement of the screw hole. In this way, the two sets of symmetrical lateral limiting parts can form lateral constraints from both sides of the reinforcing structure. When the blower output end cover is subjected to lateral force during processing, it can effectively prevent it from deflecting. Combined with the longitudinal pressing and positioning of the positioning fixture, a stable constraint is formed on the end cover from both longitudinal and lateral dimensions, which significantly improves the positioning stability during end cover processing and ensures the dimensional accuracy and geometric tolerance of the inner wall processing.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Reference Figure 1-7As shown, a high-speed output end cover tooling for a smart fan is provided. The tooling mainly consists of a base plate 1, a processing table 2 mounted on the top surface of the base plate 1, a fan output end cover 3 placed on the processing table 2, and three sets of positioning fixtures arranged in a triangular shape around the outer periphery of the processing table 2. The positioning fixtures are used to longitudinally press and position the fan output end cover 3.

[0028] The substrate 1 is a plate-shaped structure with a hollow center. The processing table 2 is ring-shaped and can be detachably installed on the top center of the substrate 1 by bolts. The inner side of the processing table 2 is connected to the hollow groove in the center of the substrate 1.

[0029] The fan output end cover 3 is integrally formed by the end cover body 31, the sealing and fitting structure 32 and the reinforcing structure 33. The sealing and fitting structure 32 is located on the bottom surface of the end cover body 31 and can be movably inserted into the inner side of the processing table 2. The reinforcing structure 33 is located on the top surface of the end cover body 31.

[0030] The positioning fixture includes a clamping block 4 that can be deflected and mounted above the processing table 2. One end of the clamping block 4 is fixedly connected to a rotating shaft 5. The bottom end of the rotating shaft 5 is rotatably connected to the top surface of the substrate 1 through a bearing embedded in the top surface of the substrate 1. The other end of the clamping block 4 abuts against the top surface of the fan output end cover 3. A positioning screw 6 slides through the middle of the clamping block 4 in the vertical direction. The bottom end of the positioning screw 6 is threaded with a nut 7, which is fixedly connected to the top surface of the substrate 1.

[0031] With the setting of the processing table 2 and the positioning fixture, the limiting hole groove of the processing table 2 can form a preliminary movable insertion positioning of the sealing fit structure 32 of the fan output end cover 3, providing a positioning basis for the fan output end cover 3; at the same time, the clamping block 4 of the positioning fixture can not only rotate around the rotating shaft 5 to facilitate the picking and putting of the fan output end cover 3, but also, after rotating to above the fan output end cover 3, by screwing the positioning screw 6, its bottom end is screwed into the nut 7 under the thread structure, so that the clamping block 4 can press the fan output end cover 3 from above, relatively ensuring the stability of the fan output end cover 3 during the processing.

[0032] Furthermore, referring to Figure 5 and Figure 6 As shown, it is worth noting that the tooling also includes a lateral limiting part for preventing the fan output end cover 3 from deflecting during processing. The lateral limiting part is arranged in two symmetrical sets, and the two sets of lateral limiting parts respectively abut against both sides of one end of the reinforcing structure 33.

[0033] The lateral limiting part includes a convex positioning seat 8 that is detachably mounted on the top surface of the substrate 1 by bolts. The top of the positioning seat 8 is provided with a deflectable movable clamp 9. The movable clamp 9 has an L-shaped structure and one end is provided with a telescopically adjustable extrusion screw 11. The cap end of the extrusion screw abuts against the side wall of the reinforcing structure 33.

[0034] A support column 10 is fixedly inserted through the inner wall at the corner of the movable clamp 9. The bottom end of the support column 10 is rotatably connected to the top surface of the positioning seat 8 through a bearing.

[0035] The other end of the movable clamp 9 has a notch 12, into which a locking screw 13 is inserted. A metal washer is provided between the nut of the locking screw 13 and the movable clamp 9. The top of the positioning seat 8 has a screw hole that matches the locking screw 13.

[0036] By setting the lateral limiting part, the movable clamp 9 can be deflected around the support column 10 first, so that the cap end of the extrusion screw 11 abuts against the side wall of the reinforcing structure 33. Then, the locking screw 13 is tightened, and the position of the movable clamp 9 is fixed by the buffer of the metal washer and the thread engagement of the screw hole. In this way, the two sets of symmetrical lateral limiting parts can form lateral constraints from both sides of the reinforcing structure 33. When the blower output end cover 3 is subjected to lateral force during processing, it can effectively prevent it from deflecting. With the longitudinal pressing and positioning of the positioning fixture, a stable constraint is formed on the end cover from both longitudinal and lateral dimensions, which significantly improves the positioning stability during end cover processing and ensures the dimensional accuracy and geometric tolerance of the inner wall processing.

[0037] Furthermore, referring to Figure 6 As shown, it is worth noting that a retraction channel 14 adapted to the extrusion screw 11 is transversely penetrating the inner wall of the movable clamp 9. The rod end of the extrusion screw 11 slides into the retraction channel 14, and a nut 15 fixed to the side wall of the movable clamp 9 is threaded on its rod body.

[0038] With the setting of the extrusion screw 11 and nut 15, when the extrusion screw 11 is rotated, since the nut 15 is fixed to the side wall of the movable clamp 9 and forms a threaded engagement with the extrusion screw 11, the extrusion screw 11 will move axially along the shrinkage channel 14 under the action of the threaded transmission. The extension length of the extrusion screw 11 can be precisely controlled, and it can easily adapt to the reinforcing structure 33 of the fan output end cover 3 of different sizes, ensuring that its cap end can tightly and evenly abut against the side wall of the reinforcing structure 33.

[0039] Furthermore, referring to Figure 7 As shown, it is worth noting that an adjusting pressure block 16 is inserted through the end of the clamping block 4 away from the rotating shaft 5, and a push-pull component for adjusting the pressure block 16 to move up and down is also provided on the top of the clamping block 4.

[0040] The push-pull component includes a limiting piece 17 fixed to the top surface of the clamping block 4 in an inverted L shape. The side wall of the adjusting block 16 slides in contact with the vertical inner wall of the limiting piece. The top of the limiting piece 17 is rotatably connected to the top of the adjusting block. The push-pull screw 18 is threaded on the body of the push-pull screw 18 and fixed with the top surface of the limiting piece 17.

[0041] By adjusting the settings of the pressure block 16 and the push-pull component, the longitudinal pressing height can be flexibly adjusted for the fan output end cover 3 of different thicknesses, further improving the adaptability and pressing accuracy of the positioning fixture. Rotating the push-pull screw 18, since the nut 19 is fixed to the top surface of the limiting plate 17 and forms a threaded engagement with the push-pull screw 18, the push-pull screw 18 will drive the adjusting pressure block 16 to rise and fall vertically under the action of the threaded transmission. During the process, the vertical inner wall of the limiting plate 17 slides in contact with the side wall of the adjusting pressure block 16, which can guide and constrain the rising and falling direction of the adjusting pressure block 16, preventing it from shifting laterally and ensuring accurate pressing position. At the same time, the self-locking characteristic of the threaded structure can keep the adjusting pressure block 16 stably at the set height, and it will not rise and fall on its own due to processing vibration. It can adapt to the end cover body 31 of different thicknesses, and can prevent the end cover from being deformed by pressure by precisely controlling the pressing height. Combined with the longitudinal pressing function of the positioning fixture, it further ensures the longitudinal positioning stability of the fan output end cover 3 during processing.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
