Description

Technical Field

[0001] This application relates to the field of fan processing equipment, and in particular to a multi-station fan processing device. Background Technology

[0002] Fan processing equipment plays a vital role in modern industrial production, especially in the machinery manufacturing field. Its efficient and precise processing capabilities greatly improve the quality and production efficiency of fan products. With the continuous growth of market demand, multi-station processing equipment has attracted widespread attention due to its ability to integrate multiple processes. This equipment not only significantly reduces the transfer time of workpieces between different devices but also improves processing accuracy and consistency, thereby bringing higher economic benefits to enterprises. Multi-station processing technology is of great significance in fan manufacturing, and its development trend is moving towards integration and automation. In existing multi-station fan processing technology, integrated design is typically used to complete multiple processing tasks, usually including: a feeding mechanism, a positioning mechanism, and a drilling mechanism. Its working principle is as follows: the fan is first fed and precisely delivered by the feeding mechanism using a synchronous belt module driven by a servo motor. After the positioning mechanism quickly locks the fan, the drilling mechanism typically uses a high-speed electric spindle carrying a carbide-coated drill bit, combined with a pressure foot pre-clamping device, to complete the synchronous processing of multiple holes on one or both sides of the fan. These devices utilize multiple fixed processing units working collaboratively to achieve multi-stage processing of fan workpieces. However, while existing multi-station fan processing devices can achieve certain multi-station processing functions, they still have significant shortcomings in practical applications. This is especially true for fans requiring angled drilling at specific angles, where electrical wires can be routed from the fan. When processing such fans, existing multi-station fan processing devices cannot complete the mounting hole and angled drilling in one go. Often, the fan needs to be drilled with mounting holes, single-sided drilling, and double-sided drilling before a second angled drilling is performed. This not only increases operational complexity but also can lead to accuracy deviations during multiple clamping processes when changing devices, thus affecting the quality of the final product. Furthermore, this multi-stage processing method significantly reduces processing efficiency and cannot meet the demands of modern industry for high-efficiency, high-precision processing. Utility Model Content

[0003] To simplify the operation process of multi-station fan machining, enable simultaneous completion of fan mounting holes and inclined drilling, improve machining efficiency, and ensure high-precision operation in a single machining operation, a multi-station fan machining device is provided.

[0004] A multi-station fan processing device includes a frame. The frame is equipped with a feeding mechanism, a positioning mechanism, and a drilling mechanism according to the fan processing flow. The feeding mechanism includes a conveyor belt and a guide rail. The guide rail is mounted on the frame, and guide side plates are vertically arranged on both sides of the guide rail. The conveyor belt is mounted on the guide rail and located between the two guide side plates for conveying the fan. The device is characterized in that...

[0005] The drilling mechanism includes an inclined drilling assembly and a mounting hole drilling assembly, which are respectively disposed on both sides of the guide rail. Each of the two guide side plates has a mounting hole through-hole corresponding to the fan center plate. The mounting hole drill bit of the mounting hole drilling assembly penetrates through the two mounting hole through-holes and the fan center plate from one side to form a fan mounting hole. An opening is provided on the upper surface of the guide side plate near the inclined drilling assembly, and the opening communicates with the corresponding mounting hole through-hole. The inclined drilling assembly is located above the guide rail and includes an inclined drive component and an inclined drill bit. The inclined drive component is disposed on the frame, and the inclined drill bit is inclined. The inclined drive component drives the inclined drill bit to sequentially penetrate the opening and the mounting hole through-hole, drilling from one side of the fan center plate to form an inclined hole. By adopting the above technical solution, the cooperation of the conveyor belt and the guide rail can achieve precise fan transport, ensuring that the fan maintains a stable position during processing. The through-hole design on the guide plate provides a path for the mounting hole drill bit, enabling precise drilling of mounting holes on the fan center plate. In particular, the inclined drilling assembly solves the problem of existing technologies being unable to complete inclined drilling in a single operation. Specifically, the drive unit propels the inclined drill bit through the opening and through-hole sequentially, ultimately reaching one side of the fan center plate to perform the drilling operation, thus forming the required inclined hole. This design not only avoids accuracy deviations caused by secondary processing but also cleverly utilizes time gaps. Specifically, the inclined drill bit begins its inclined drilling operation the instant the mounting hole drill bit completes drilling and retracts. This method not only rationally utilizes the time gaps during the mounting hole drill bit's drilling process but also effectively avoids the additional time required for inclined drilling, thereby significantly improving overall processing efficiency, reducing waiting time between processing steps, and further enhancing the production efficiency of the fan processing equipment. Furthermore, the connection between the opening and through-hole provides reliable guidance for the movement of the inclined drill bit, ensuring the smoothness and accuracy of the drilling process. Preferably, the opening and the through hole of the mounting hole form a guide groove. The guide groove is provided with a linear guide portion. A guide block is provided at one end of the inclined drill bit near the inclined drive component. The inclined drive component drives the inclined drill bit to pass through the guide groove, and the guide block slides along the linear guide portion, with the guide block and the linear guide portion in close contact. By adopting the above technical solution, the inclined drill bit can slide precisely along the linear guide portion in the guide groove under the drive of the drive component. Because the guide block and the linear guide portion are in close contact, this design ensures that the inclined drill bit maintains stability and accuracy during movement. Specifically, when the drive component drives the inclined drill bit to pass through the guide groove, the constraint of the guide block along the linear guide portion effectively prevents the inclined drill bit from deviating or shaking during processing, thereby ensuring the processing accuracy of the inclined hole.Furthermore, the guide groove design provides a clear movement path for the tilting drill bit, further improving the consistency and reliability of drilling operations. Preferably, the drill bit portion of the tilting drill bit is located within the guide groove, and the distance between it and the fan center plate ranges from 0.2cm to 2cm. By adopting the above technical solution, the initial position of the drill bit portion of the tilting drill bit is precisely limited within the guide groove, maintaining a distance of 0.2cm to 2cm from the fan center plate. This design ensures precise positioning during tilting drilling operations, avoiding fan jamming due to excessive proximity of the drill bit, or processing errors caused by excessive distance from the fan center plate, as well as extending the tilting drilling time. Specifically, controlling the distance between the drill bit and the fan center plate within a reasonable range not only effectively prevents unnecessary damage to the fan surface from the drill bit but also ensures the consistency of drilling depth. In addition, the selection of this distance range has been carefully considered, meeting the processing requirements of fans of different sizes while reducing adjustment time in actual operation, thereby improving overall processing efficiency and accuracy. Preferably, the angle between the inclined drill bit and the vertical guide plate ranges from 5° to 30°. By adopting the above technical solution, the angle range of 5° to 30° between the inclined drill bit and the vertical guide plate allows the drilling mechanism to accurately adapt to the inclined hole processing requirements of fans of different specifications. This design is based on the angle variation range of fan lead hole in actual applications. By limiting the angle of the inclined drill bit within a reasonable range, it not only ensures the accuracy and consistency of drilling but also effectively avoids the problems of increased processing difficulty and decreased equipment stability caused by excessively large or small angles. At the same time, the setting of this angle range combines a comprehensive consideration of material properties and processing efficiency, which can reduce drill bit wear and extend equipment service life while ensuring hole position accuracy. Preferably, the drilling mechanism further includes a front drilling assembly and a back drilling assembly respectively disposed on both sides of the guide rail. The two guide side plates are respectively provided with front through holes and back through holes corresponding to the fan. The front drilling assembly includes a front drive component and a front drill bit. The front drive component drives the front drill bit to drill through the front through hole to form a front hole. The back drilling assembly includes a back drive component and a back drill bit. The back drive component drives the back drill bit to drill through the back through hole to form a back hole. By adopting the above technical solution, the drilling mechanism adds front drilling assemblies and back drilling assemblies respectively located on both sides of the guide rail, enabling drilling operations on both the front and back sides of the fan to be completed in one operation. Specifically, the front drive unit in the front drilling assembly drives the front drill bit through the front through hole on the guide side plate to precisely drill the fan to form a front face; at the same time, the back drive unit in the back drilling assembly drives the back drill bit through the back through hole on the guide side plate to drill the back of the fan to form a back face.This design eliminates the need for flipping or repositioning the blower during processing, thus avoiding precision errors caused by multiple clamping operations and significantly improving processing efficiency and hole position accuracy. Furthermore, integrating front and back drilling functions into the same device reduces equipment space requirements and further optimizes the overall processing flow. Preferably, the blower processing device also includes a slag removal mechanism, which is mounted on the frame and located between the positioning mechanism and the drilling mechanism. The slag removal device includes a slag removal drive, a slag removal head, and a slag discharge component. The slag removal drive is mounted on the frame, and the slag discharge component is located at the outlet of the slag removal head. The slag removal drive drives the slag removal head through the guide side plate to remove slag from the blower, and the slag discharge component collects and discharges the waste slag from the outlet of the slag removal head. By adopting the above technical solution, the slag removal mechanism can effectively remove waste chips and impurities generated during the initial processing of the blower. Specifically, after the blower is fixed by the positioning mechanism, before entering the drilling mechanism, the slag removal drive is activated and pushes the slag removal head through the guide side plate to clean the interior of the blower. Because the slag removal head is designed to precisely fit the processing area of ​​the blower, it can efficiently remove residual metal shavings or other impurities, preventing these impurities from affecting the accuracy and quality of subsequent drilling processes. Simultaneously, the slag discharge component, located at the outlet of the slag removal head, can promptly collect waste slag discharged from inside the blower and guide it to an external waste collection system, preventing waste slag from scattering into the device and causing secondary pollution or damage to other components. This design not only improves the quality of pre-processing preparation but also significantly reduces the risk of equipment failure due to residual waste shavings, thereby improving overall processing efficiency and product yield. Preferably, the blower processing device also includes a condensation mechanism, which includes a condensation drive, several condensation components, and several connecting pipes. Each condensation component is connected to the condensation drive through a corresponding connecting pipe of varying length. The condensation drive is mounted on the frame, and both the slag removal mechanism and the drilling mechanism are equipped with corresponding condensation components for cooling. By adopting the above technical solution, the condensation mechanism can effectively reduce the heat generated by the slag removal mechanism and the drilling mechanism during operation. Specifically, the condensing drive unit delivers cooling medium to the corresponding condensing components of each processing mechanism through connecting pipes of varying lengths. The varying pipe lengths ensure that the cooling medium is distributed as needed, thereby achieving precise cooling of each processing mechanism. This design not only improves cooling efficiency but also avoids equipment damage or decreased processing accuracy due to overheating, thus guaranteeing the stable operation and high efficiency of the entire multi-station fan processing device. Preferably, the frame is equipped with several drain outlets. By adopting the above technical solution and providing several drain outlets on the frame, the problem of coolant or waste liquid residue on the frame surface generated during processing can be effectively solved.Specifically, during operation, the multi-station fan-operated machining unit sprays coolant from the condensation mechanism to cool each machining unit. Simultaneously, the slag removal mechanism may generate waste liquid while removing waste slag. If this liquid is not drained promptly, it can accumulate on the machine frame surface, leading to equipment corrosion or affecting machining accuracy. By strategically arranging drain outlets on the machine frame, waste liquid can be guided to drain quickly, keeping the frame surface clean and dry, thereby extending the equipment's lifespan and ensuring a stable machining environment. Furthermore, the drain outlet design prevents waste liquid from flowing into the machining area, further improving machining quality and efficiency.

[0006] In summary, this application includes at least one of the following beneficial technical effects:

[0007] 1. By setting inclined drilling components and mounting hole drilling components on both sides of the guide rail, mounting hole and inclined drilling can be completed simultaneously in a single clamping process. This design avoids the problem of needing multiple clampings to complete drilling at different angles in traditional multi-station machining, thereby significantly improving machining efficiency and reducing accuracy deviations caused by multiple clampings;

[0008] 2. The guide groove design in the tilting drilling assembly, combined with the tight fit between the linear guide section and the guide block on the tilting drill bit, ensures a stable and precise movement trajectory of the tilting drill bit during machining. Because the guide block slides along the linear guide section, it effectively prevents the tilting drill bit from shifting or vibrating during machining, thereby improving the quality and accuracy of hole machining.

[0009] 3. The drill bit is kept within a distance of 0.2cm to 2cm from the fan center plate. This optimized design avoids potential damage caused by the drill bit getting too close to the fan center plate while ensuring consistent and reliable drilling depth. This appropriate distance range makes the drilling process more controllable, further improving processing stability and product yield. Attached Figure Description

[0014] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0015] This application discloses a multi-station fan processing apparatus, referring to... Figure 1 The device consists of a frame 1 and a feeding mechanism 2, a positioning mechanism 3, a slag removal mechanism 4, a drilling mechanism 5, and a condensing mechanism 6, all mounted on the frame 1. The fan is processed sequentially through the feeding mechanism 2, positioning mechanism 3, slag removal mechanism 4, and drilling mechanism 5. The condensing mechanism 6 assists in cooling the fan during each process. Specifically, in this embodiment, the frame 1 is horizontally positioned to keep the fan on the same horizontal plane, improving the processing accuracy of the fan. The aforementioned mechanisms can be installed according to a straight production line design, or they can be rationally laid out according to the specific factory area, for example, they can be designed as a straight production line, a "U"-shaped production line, or an "S"-shaped production line.

[0016] Reference Figure 2 Specifically, the feeding mechanism 2 in this embodiment includes a conveyor belt 21 for conveying the blower and a guide rail 22 for guiding the blower along a preset path. The guide rail 22 has a "U" shaped structure, and guide side plates 23 are vertically arranged on both sides of the guide rail 22. The conveyor belt 21 is located between the two guide side plates 23 for conveying the blower. The blower in this embodiment has a cuboid structure. The blower is placed in the guide rail 22, and the distance between the two vertical guide side plates 23 is approximately the same as the width of the blower. This avoids the gap between the blower and the guide side plates 23 being too small, which can easily cause the blower to jam, or the gap being too large, which can easily cause the blower to shake within the guide rail 22, resulting in inconsistent blower positions and thus causing processing deviations and compromising processing accuracy.

[0017] Reference Figure 2 Specifically, the positioning device in this embodiment includes a positioning drive cylinder 31, a limiting platform 32, and a push rod 33. The blower is conveyed from the feeding structure to the limiting platform 32 of the positioning mechanism 3 for limiting. The positioning drive cylinder 31 drives the push rod 33 to limit the blower on the limiting platform 32, so that the blower can enter the guide channel corresponding to the slag removal device according to the preset path, so that the slag removal mechanism 4 can perform slag removal operation on the blower.

[0018] Reference Figure 2 Specifically, the slag removal mechanism 4 in this embodiment includes a slag removal drive component 41, a slag removal head 42, and a slag discharge component 43. The slag removal drive component 41 can be a power source such as a linear motor or a cylinder. For example, the linear motor is connected to the slag removal head 42 via a slide rail, and the cylinder is connected to the slag removal head via a piston rod. The slag removal head 42 is made of stainless steel or wear-resistant ceramic material, and the slag discharge component 43 is a downward-sloping slag discharge pipe structure to prevent waste slag from accumulating at the discharge port and to facilitate effective collection and discharge of waste slag.

[0019] Reference Figure 2 Specifically, the drilling mechanism 5 in this embodiment includes a mounting hole drilling assembly 51, an inclined drilling assembly 52, a front drilling assembly 53, and a back drilling assembly 54. The inclined drilling assembly 52 and the mounting hole drilling assembly 51 are respectively disposed on both sides of the guide rail 22, and the front drilling assembly 53 and the back drilling assembly 54 are respectively disposed on both sides of the guide rail 22. The inclined drilling assembly 52 and the front drilling assembly 53 are located on the same side, and the mounting hole drilling assembly 51 and the back drilling assembly 54 are located on the same side. Both guide side plates 23 have mounting holes 23a2 corresponding to the center of the fan's central disk. The upper surface of the guide side plate 23 near the inclined drilling assembly 52 has an opening 23a1, which connects with the corresponding mounting hole 23a2 to form a guide groove 23a. Furthermore, the guide side plate 23 on the same side as the front drilling assembly 53 has four front through holes corresponding to the four corners of the fan, and the guide side plate 23 on the same side as the reverse drilling assembly 54 has four reverse through holes corresponding to the four corners of the other side of the fan. The guide groove 23a has a combined shape of an arc and a cuboid; the arc area corresponds to the center of the fan, and the cuboid area has a straight guide section 23a3.

[0020] Reference Figure 2Specifically, the mounting hole drilling assembly 51 includes a mounting hole drive 511 and a mounting hole drill bit 512. The mounting hole drive is mounted on the frame 1. The drive motor drives the mounting hole drill bit 512 to drill through the through holes of the two guide side plates 23 and the central disc of the fan located between the two guide side plates 23, thereby drilling the fan mounting hole. The mounting hole drive 511 can be a power source such as a stepper motor or a pneumatic motor. For example, the stepper motor is connected to the mounting hole drill bit 512 via a synchronous belt, and the pneumatic motor is connected to the mounting hole drill bit 512 via a drive shaft. The mounting hole drill bit 512 is a carbide-coated drill bit or a high-speed steel drill bit. (Refer to...) Figure 3 Specifically, the inclined drilling assembly 52 is located above the guide rail 22. The inclined drilling assembly 52 includes an inclined drive component 521 and an inclined drill bit 522. The inclined drive component 521 can be a power source such as a servo motor or a hydraulic cylinder. For example, the servo motor is connected to the inclined drill bit 522 via a coupling, and the hydraulic cylinder is connected to the inclined drill bit 522 via a piston rod. The inclined drill bit 522 uses a carbide-coated drill bit or a high-speed steel drill bit, and it forms an angle range of 5°-30° with the vertical guide side plate 23, such as 5°, 15°, or 30°, depending on the actual fan model. The drill bit portion of the inclined drill bit 522 is located within the guide groove 23a, and the distance between it and the fan center plate ranges from 0.2cm to 2cm, such as 0.5cm or 1.5cm. In addition, a cuboid guide block 523 is provided at one end of the inclined drill bit 522 near the inclined drive member 521. When the inclined drilling assembly 52 is not working, the initial state is that a part of the cuboid guide block 523 is in contact with the cuboid straight guide portion 23a3, and the inclination angle of the inclined drill bit 522 is consistent with the inclination angle of the cuboid guide block 523. When the inclined drive member 521 drives the inclined drill bit 522 to pass through the guide groove 23a and approach the center plate of the blower, the guide block 523 slides along the straight guide portion 23a3 and fits tightly, which can ensure the stability and accuracy of the drilling process.

[0021] Specifically, the front drilling assembly 53 and the back drilling assembly 54 are symmetrically arranged on both sides of the guide rail 22. Guide side plates 23 adapted to the parts of the fan housing to be processed are fixedly connected to both sides of the guide rail 22. The guide side plates 23 correspond to the front through holes on the front side and the back through holes on the back side of the fan housing, and the coaxiality error of the two through holes is ≤0.05mm. The front drilling assembly 53 consists of a front drive component 531 and a front drill bit 532, and the back drilling assembly 54 includes a back drive component 541 and a back drill bit 54. 2; The front drive component 531 is a hydraulic motor with an integrated torque sensor, which drives the front drill bit 532 to pass through the front through hole and form a front hole on the front of the fan housing; the back drive component 541 is a hydraulic motor with an integrated torque sensor, which drives the back drill bit 542 to pass through the back through hole and form a back hole on the back of the fan housing; the double-sided drilling operation uses atomized coolant spraying on the processing area throughout the process, and finally achieves the technical requirements of coaxiality of the double-sided holes of the fan housing ≤0.1mm and hole wall roughness Ra≤3.2μm.

[0022] In addition, the multi-station fan processing device also includes a condensing mechanism 6 installed at multiple stations. The condensing mechanism 6 includes a condensing drive unit 61, several condensing components 62, and several connecting pipes 63. The condensing drive unit 61 can be a power source such as a water pump or compressor, and the condensing components 62 adopt structures such as copper pipes or aluminum heat sinks. The water pump is connected to the condensing components 62 through pipes, and the compressor is connected to the condensing components 62 through refrigerant pipes. The different lengths of the connecting pipes 63 allow them to act on the slag removal mechanism 4 and the drilling mechanism 5 at different distances, providing full-process cooling for the fan. Specifically, the frame 1 is equipped with drain outlets 7 at each station to facilitate rapid discharge of coolant, ensuring continuous and stable operation of the processing device. The implementation principle of this embodiment is as follows: The fan passes through each workstation sequentially via a horizontally set frame 1. First, the fan is conveyed and guided by the conveyor belt 21 of the feeding mechanism 2 and the U-shaped guide rail 22 with the opening 23a1 facing upward (guide side plates 23 are provided on both sides, with the spacing adapted to the width of the fan). Then, the fan enters the positioning mechanism 3, where the drive cylinder drives the push rod 33 to push it from the limiting platform 32 to the guide channel corresponding to the slag removal mechanism 4. In the slag removal mechanism 4, the slag removal drive component 41 drives the slag removal head 42 to work, and the slag discharge component 43 discharges the waste slag through the slag discharge channel. Next, the fan enters the drilling mechanism 5, where the inclined drilling assembly 52, the mounting hole drilling assembly 51, the front drilling assembly 53, and the back drilling assembly 54 drill holes in the fan from different positions and angles. The mounting hole drilling assembly 51 drives the drill bit to penetrate the guide. Holes are drilled in the side plate 23 and the fan center plate. The inclined drill bit 522 of the inclined drilling assembly 52 operates within the guide groove 23a, and the guide block 523 of the inclined drilling assembly 52 can slide in contact with the straight guide portion of the guide groove 23a, guiding the inclined drill bit 522 to achieve precise drilling. Front and back drilling assemblies 54 are arranged on both sides of the guide plate 23. At the same time, the condensing mechanism 6 set at each station drives the condensing assembly 62 through the condensing drive 61 and connecting pipes 63 of different lengths to perform full-process cooling treatment on the fan in each process. Drainage outlets 7 are set at each station of the frame 1 to facilitate the discharge of coolant, so as to ensure the precise processing of the fan and the stable operation of the device, simplify the operation process of multi-station processing of the fan, and can simultaneously complete the fan mounting hole and inclined drilling, improve processing efficiency, and ensure high-precision operation of one processing. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
