Description

Technical Field

[0001] This invention belongs to the field of wind turbine manufacturing tooling technology, specifically relating to an intelligent wind turbine conveying end cover tooling. Background Technology

[0002] The fan inlet end cover is a core component in fan assembly. Its manufacturing precision directly determines the running accuracy of the main shaft, the vibration and noise level of the whole machine, and its service life.

[0003] Currently, in the processing of the input end cover of the fan, a robot or clamping fixture is generally used to fix the end cover by circumferential clamping before grinding or drilling. However, since the end cover of the fan is relatively large, resonance is prone to occur during processing. Therefore, the above clamping method is prone to axial vibration of the end cover of the fan during processing, which leads to a reduction in processing accuracy.

[0004] In view of this, the present invention provides an intelligent fan conveyor end cover tooling to solve the above problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smart fan conveying end cover tooling, comprising: a tooling body for horizontally fixing a workpiece, which includes a base and a plurality of locking support mechanisms spaced apart on the top surface of the base;

[0006] The locking support mechanism includes a locking support component one and a locking support component two disposed adjacent to the locking support component one. The locking support component one and the locking support component two respectively generate locking forces on both ends of the workpiece in a direction perpendicular to the horizontal direction, so as to form a balanced clamping force field between the two ends of the workpiece.

[0007] As a preferred embodiment of the intelligent fan conveying end cover tooling of the present invention, the locking support assembly includes a bracket for supporting the lower end face of the workpiece, and a locking bolt that extends from bottom to top through the top surface of the bracket and engages with the workpiece.

[0008] The second locking support assembly includes a second bracket for supporting the lower end face of the workpiece, and a second locking bolt that passes through the workpiece from top to bottom and screws into the second bracket.

[0009] As a preferred embodiment of the intelligent fan conveying end cover tooling of the present invention, at least one set of support members for supporting the bottom surface of the workpiece is further provided between adjacent locking support mechanisms.

[0010] As a preferred embodiment of the intelligent fan conveying end cover tooling of the present invention, the supporting member includes a columnar portion vertically connected to the top surface of the base, and a supporting portion axially movable and connected to the top of the columnar portion.

[0011] As a preferred embodiment of the intelligent fan conveying end cover tooling of the present invention, a movable pressing mechanism for applying uniform downward pressure to the upper end surface of the workpiece is further provided at the center of the top surface of the base. The downward pressure generated by the movable pressing mechanism is less than the strength of the clamping force field on the workpiece.

[0012] As a preferred embodiment of the intelligent fan conveyor end cover tooling of the present invention, the movable pressing mechanism includes a drive component, a plurality of pressing action components equally spaced around the drive component, and a connector connecting the drive component and the pressing action components.

[0013] As a preferred embodiment of the intelligent fan conveying end cover tooling of the present invention, the pressing action assembly includes a positioning seat detachably connected to the top surface of the base, a movable shaft with one end movable along a specific path inside the positioning seat, and a pressing block and a helical gear respectively axially connected to the upper and lower ends of the movable shaft.

[0014] The positioning seat also has a helical rack inserted inside that meshes with the helical gear and is movably connected to the connector.

[0015] As a preferred embodiment of the intelligent fan conveyor end cover tooling of the present invention, a guide groove is provided on the periphery of the movable shaft, and one end of the guide post connected to the positioning seat extends into the guide groove to limit the movement path of the movable shaft.

[0016] As a preferred embodiment of the intelligent fan conveying end cover tooling of the present invention, the driving assembly includes a rotating disk axially connected to the top surface of the base, and a driving component for driving the rotating disk to rotate along its axial direction.

[0017] As a preferred embodiment of the intelligent fan conveying end cover tooling of the present invention, the other end of the connector away from the helical rack is movably connected to the rotating disk. When the rotating disk rotates, it can drive the connector to move along the tangential direction of the helical gear.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The locking support mechanism formed by the locking support component one and the locking support component two of the present invention can generate relative locking forces at the upper and lower ends of the workpiece respectively to provide a balanced clamping position, thereby fixing the workpiece while reducing the axial vibration of the workpiece and improving the machining accuracy.

[0020] 2. The present invention further provides support members between adjacent locking support mechanisms, which can further support the bottom surface of the workpiece, thereby effectively reducing the span between the locking support mechanisms, reducing the deformation of the workpiece, and further improving the processing accuracy.

[0021] 3. By providing an active pressing mechanism with a downward pressure intensity less than the clamping force field applied to the workpiece, the present invention further ensures the stability of the workpiece while ensuring that it is subjected to a balanced clamping force field, so that it can resist greater external loads and improve machining accuracy.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] This invention relates to an intelligent fan conveyor end cover tooling, such as... Figures 1-2 As shown, it includes a tooling body 1 for horizontally fixing a workpiece, which includes a base 11 for mounting on a processing equipment such as a CNC machine tool, and a plurality of locking support mechanisms spaced apart on the top surface of the base 11.

[0034] The workpiece is a large fan conveyor end cover, which is circular in shape. Therefore, the locking support mechanism is arranged in a ring with equal spacing to provide uniform support for the workpiece. Of course, in addition to the ring arrangement, the position can be adjusted according to the actual shape of the workpiece to ensure uniform support and locking force. It includes a locking support assembly 12 and a locking support assembly 13 adjacent to it. The locking support assembly 12 and the locking support assembly 13 respectively generate locking forces on both ends of the workpiece in a direction perpendicular to the horizontal, forming a balanced clamping force field between the two ends of the workpiece.

[0035] Specifically, the locking support assembly 12 includes a bracket 1 for supporting the lower end face of the workpiece, and a locking bolt 121 that passes through the top surface of the bracket 1 from bottom to top and screws onto the workpiece. In this embodiment, the bracket 1 has a "U"-shaped structure with a through hole vertically opened at its top. The locking bolt is a bolt adapted to a positioning hole opened on the surface of the workpiece. After passing through the through hole from bottom to top, the bolt is threadedly connected to the corresponding positioning hole of the workpiece to generate an upward locking force on the workpiece.

[0036] The locking support assembly 2 13 includes a bracket 2 for supporting the lower end face of the workpiece, and a locking bolt 2 131 that passes through the workpiece from top to bottom and screws into the bracket 2. In this embodiment, the bracket 2 has a trapezoidal structure, and a threaded hole corresponding to the positioning hole on the surface of the workpiece is vertically opened at its top. The locking bolt 2 131 is a bolt that is inserted into the positioning hole on the surface of the workpiece from top to bottom and then threadedly connected to the threaded hole, generating a downward locking force on the workpiece. This locking force is alternately opposite to the locking force generated by the locking support assembly 1 12, so as to form a balanced clamping force field at the upper and lower ends of the workpiece, thereby stabilizing the workpiece and improving the machining accuracy.

[0037] Example 2:

[0038] Because the locking support mechanisms are spaced apart, adjacent locking support mechanisms form a support span when supporting the workpiece. Between this span, the bottom surface of the workpiece is suspended. Therefore, during machining, this suspended area will experience axial vibration due to the machining force, thus reducing machining accuracy. This embodiment, based on the first embodiment described above, further provides several support members 14, combined with... Figures 1-2 .

[0039] The support members 14 are evenly arranged between adjacent locking support mechanisms. Each member includes a columnar portion vertically connected to the top surface of the base 11, and a support portion axially movable to the top of the columnar portion. In this embodiment, the top of the columnar portion has an axially threaded hole. The support portion is a bolt threaded into this threaded hole. The bolt head abuts against the workpiece, providing support. Furthermore, the height of the bolt head can be adjusted by the depth to which the bolt is screwed into the threaded hole, allowing for adaptive adjustments based on the workpiece's suspension height within the support span, thus improving practicality.

[0040] In addition to providing effective support to the workpiece through the auxiliary locking support mechanism of the support member 14, it can also effectively shorten the support span between the locking support mechanisms, thereby effectively reducing the workpiece deformation under the support span, reducing processing vibration, and improving processing accuracy.

[0041] Example 3:

[0042] Figures 3-7 The third embodiment of the present invention is shown, which differs from the first or second embodiment described above only in that: an active pressing mechanism 2 for applying uniform downward pressure to the upper end surface of the workpiece is provided at the center of the top surface of the base 11. The downward pressure generated by the active pressing mechanism 2 is less than the intensity of the clamping force field on the workpiece, thereby further limiting the vibration of the workpiece and improving the processing accuracy without disrupting the balance of the clamping force field.

[0043] The movable pressing mechanism 2 includes a drive assembly 21, a plurality of pressing action components 22 equally spaced around the drive assembly 21, and a connector 23 connecting the drive assembly 21 and the pressing action components 22. When the drive assembly 21 is running, it can drive the connector 23 to move, thereby driving the pressing action components 22 to press the workpiece, so as to improve the pressing accuracy.

[0044] Specifically, the drive assembly 21 includes a rotating disk 212 axially connected to the top surface of the base 11, and a drive member 211 installed at the bottom of the base 11 with its output end axially extending to connect to the rotating disk 212. In this embodiment, the drive member 211 is a servo motor, which can drive the rotating disk 212 to rotate to provide power for the movement of the connector 23 when it is running.

[0045] The pressing action assembly 22 includes a positioning seat 221 detachably connected to the top surface of the base 11 by fasteners, a movable shaft 222 disposed inside the positioning seat 221 with one end movable along a specific path, and a pressing block 223 and a helical gear 224 axially connected to the upper and lower ends of the movable shaft 222, respectively; a helical rack 225 that meshes with the helical gear 224 and is movably connected to the connector 23 is also inserted inside the positioning seat 221.

[0046] Preferably, the positioning seat 221 includes a lower seat body 2211 and an upper seat body 2212 detachably connected to the lower seat body 2211. The lower seat body 2211 has an internal movable cavity 22111 for the axial movement of the helical gear 224. The movable shaft 222 vertically passes through the upper seat body 2212 and extends into the movable cavity 22111 to be axially connected to the helical gear 224. At the same time, an "L"-shaped guide groove 226 is formed on the periphery of the movable shaft 222. One end of the guide post 227 threadedly connected to the positioning seat 221 extends into the guide groove 226 to limit the movement path of the movable shaft 222.

[0047] When the helical rack 225 moves, it drives the helical gear 224 and the movable shaft 222 to rotate. Because the helical rack 225 and the helical gear 224 engage, a radial force is generated, allowing the movable shaft 222 to move along the opening of the guide groove 226 under the constraint of the guide post 227. This enables the movable shaft 222 and the pressure block 223 connected to its top to rotate and press down, thus pressing the top surface of the workpiece. Simultaneously, if the helical rack 225 is pulled in the opposite direction, it can rotate and rise, releasing the restriction on the workpiece for disassembly. The pressure block 223 further restricts the workpiece's movement, effectively limiting vibration during machining and further improving machining accuracy.

[0048] Furthermore, the connecting member 23 includes a connecting rod 233 whose two ends are rotatably and detachably connected to the helical rack 225 and the rotating disk 212, respectively, and a connecting shaft 232 and a connecting shaft 231 that are fixedly connected to the helical rack 225 and the rotating disk 212, respectively, to achieve their rotatable connection. Preferably, multiple connecting shafts 231 can be arranged in a ring at equal intervals along the circumference or surface of the rotating disk 212, so as to increase or decrease the number of pressing action components 22 according to actual processing needs, thereby improving processing flexibility. At the same time, when the rotating disk 212 rotates, the connecting shafts 231 connected to it can rotate with it, and transmit power to the connecting rod 233, so that the connecting rod 233 provides an axial component force to the helical rack 225 to drive the helical rack 225 to move axially along the tangential direction of the helical gear 224, so as to effectively drive the pressing action components 22 to produce action.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
