Description

Technical Field

[0001] The invention relates to the technical field of impeller disassembly, and in particular to a high-efficiency fan impeller disassembly device. Background Art

[0002] The impeller is an important working part of the fan. The shaft hole of the impeller hub is connected with the main shaft by interference fit. The cross section of the shaft hole of the hub and the cross section of the main shaft are similar non-circular shapes. This design is to ensure a close fit between the impeller and the main shaft, thereby ensuring the coaxiality between them. In order to further ensure the coaxiality between the impeller and the main shaft, a cold assembly or hot assembly process can be used to further ensure the interference fit between the impeller shaft hole and the main shaft.

[0003] The existing impeller is interference fit with the main shaft, so it is time-consuming and laborious to disassemble the impeller. Generally, a hydraulic puller with a "T"-shaped sleeve is used to fix the impeller with the puller sleeve through the auxiliary hole, and then the hydraulic cylinder drives the push rod to align with the main shaft to lift it, so as to pull the impeller out from the outer surface of the main shaft. Although the impeller can be disassembled, the impeller is mainly pulled out directly by providing external force through the hydraulic cylinder. The disassembly method is relatively simple, and slight scratches will be generated between the shaft hole of the impeller and the main shaft, which is not conducive to the rapid disassembly of the impeller.

[0004] Therefore, we propose a high-efficiency fan impeller disassembly device. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1 to 11 The present invention provides a technical solution: a high-efficiency fan impeller disassembly device, comprising a hydraulic cylinder 1, wherein a push rod 11 driven by the hydraulic cylinder 1 slides inside the hydraulic cylinder 1, and a tension kit 2 is connected to the annular outer surface of the hydraulic cylinder 1 near the lower end, and the tension kit 2 comprises a receiving sleeve 20 and a connecting sleeve 21, and a bearing sleeve 16 is rotatably connected between the receiving sleeve 20 and the connecting sleeve 21, and the receiving sleeve 20 is threadedly connected to the hydraulic cylinder 1, and the user can select the distance between the receiving sleeve 20 and the hydraulic cylinder 1 according to the width of the impeller;

[0036] See also Figures 1 to 3The connecting sleeve 21 is designed in a "T" shape as a whole. The vertical part of the connecting sleeve 21 is composed of a columnar body, and the horizontal part is composed of a flat rectangular body. A longitudinal rectangular groove 22 is provided on the annular outer surface of the connecting sleeve 21. A lubrication component 3 for lubricating the impeller disassembly position is provided inside the longitudinal rectangular groove 22. The lubrication component 3 includes a storage tube 30 for storing lubricant. The discharge amount of lubricant inside the storage tube 30 is affected by the movement amount of the push rod 11. By arranging the lubrication component 3 inside the longitudinal rectangular groove 22, when the tension kit 2 and the push rod 11 interact with each other and push the impeller, the lubrication component 3 sprinkles the lubricant stored inside on the connection position of the impeller and the main shaft, allowing the lubricant to gradually penetrate into the connection position of the impeller and the main shaft, reducing the friction between the impeller and the main shaft, thereby facilitating the disassembly of the impeller and reducing scratches.

[0037] See also Figure 2 and 3 A transverse rectangular groove 23 is provided on the outer surface of the upper end of the horizontal part of the connecting sleeve 21. There are two groups of transverse rectangular grooves 23, and there are slidable positioning blocks 28 inside them. The two groups of positioning blocks 28 move toward each other or move away from each other synchronously. A spring 283 is fixedly connected between the positioning block 28 and the transverse rectangular groove 23. The bolt passes through the transverse rectangular groove 23 and is threadedly connected to the auxiliary hole on the surface of the impeller, pressing the tension kit 2 against the outer surface of the impeller, and the position of the impeller main shaft is aligned with the push rod 11. Since the auxiliary holes on the impeller surface are symmetrically designed and the midpoint of the line connecting the two is aligned with the main shaft, the synchronous movement of the two groups of positioning blocks 28 can effectively align the push rod 11 with the impeller main shaft, saving operation time.

[0038] See also Figures 3 to 6The lubrication assembly 3 also includes a slot 31, the storage tube 30 is inserted into the slot 31, the storage tube 30 is plugged in and out to facilitate the replenishment of lubricant, the slot 31 and the storage tube 30 are interference fit at the docking position, an extrusion chamber 32 is provided inside the slot 31, the extrusion chamber 32 is located inside the connecting sleeve 21, a flow hole 320 is provided on the inner surface of the extrusion chamber 32 away from the storage tube 30, a one-way valve 34 is fixedly connected to the annular inner surface of the connecting sleeve 21 near the lower end opening, the one-way valve 34 is communicated with the flow hole 320, and the influence of the thickness of the extrusion plate 33 and the wall thickness of the one-way valve 34 on the flow rate is reduced, the extrusion chamber 32 is slidably connected with the extrusion plate 33, and the upper end of the extrusion plate 33 is fixedly connected with a connecting rod 35, The upper end of the connecting rod 1 35 is rotatably connected to the connecting rod 2 36, and the end of the connecting rod 2 36 away from the connecting rod 1 35 is designed as an annular structure, and is rotatably connected to a fixing rod 39 inside thereof, and one end of the fixing rod 39 is fixedly connected to a gear 1 37, and a tooth groove 12 is provided at the corresponding position of the push rod 11 and the gear 1 37, and the gear 1 37 meshes with the tooth groove 12, and the gear 1 37 rotates inside the longitudinal rectangular groove 22. The number of the tooth grooves 12 provided on the annular outer surface of the push rod 11 is several groups, and they surround the push rod 11 for one week. After the connecting sleeve 21 is fixed to the surface of the impeller by bolts, the receiving sleeve 20 is docked with the hydraulic cylinder 1 and connected by threads. During the connection process, the push rod 11 moves toward the impeller main shaft, and the end of the push rod 11 will contact the gear 1 37. Through the design of the tooth groove 12, the gear 1 37 rotates as the push rod 11 gradually approaches the impeller, and then is driven by the connecting rod 1 35 and the connecting rod 2 36. The extrusion plate 33 moves inside the extrusion chamber 32, and the lubricant inside the extrusion chamber 32 is pressed out through the one-way valve 34. The lubricant is sprayed onto the inner wall of the push rod 11 and the connecting sleeve 21. The inner wall edge of the connecting sleeve 21 is designed as an inclined structure, which is convenient for the lubricant to flow along the inclined surface and fall between the impeller and the main shaft. When the position of the push rod 11 is determined, the hydraulic cylinder 1 is controlled to make the push rod 11 slowly resist the impeller main shaft. At this time, the connecting sleeve 21 is fixed to the impeller. With the action of the hydraulic cylinder 1, the impeller is gradually pushed out of the main shaft. During this period, the push rod 11 will slowly move toward the main shaft direction, and the gear 1 37 will also rotate to drive the connecting rod 1 35 and the connecting rod 2 36 to control the extrusion plate 33 to perform piston movement inside the extrusion chamber 32, and the lubricant inside the extrusion chamber 32 is squeezed out through the one-way valve 34. Compared with the traditional disassembly method, the above technical solution can reduce the friction between the main shaft and the impeller shaft hole and reduce scratches, thereby improving the disassembly efficiency.

[0039] See also Figure 4 and 5The number of the flow holes 320 and the one-way valve 34 are both two groups, and they are distributed on the upper and lower sides of the extrusion chamber 32. The end of the fixed rod 39 away from the gear 1 37 is fixedly connected to the gear 2 38. The gear 2 38 and the gear 1 37 are in contact with the tooth groove 12 at the same time, which increases the contact area and ensures the meshing effect. The gear 2 38, the gear 1 37 and the fixed rod 39 form a crankshaft structure. The extrusion plate 33 performs piston motion inside the extrusion chamber 32, and has two upper and lower strokes. When the extrusion plate 33 moves upward, the extrusion chamber 32 The internal lubricant is discharged through the one-way valve 34 at the top, and the lubricant in the space below the extrusion plate 33 is replenished at the same time. The source of the replenished lubricant is from the storage tube 30. When the extrusion plate 33 moves downward, the lubricant just replenished is discharged through the one-way valve 34 at the bottom, and the cycle is in sequence, so that as long as the push rod 11 moves, the lubricant will be sprayed out from the inside of the one-way valve 34, thereby improving the disassembly effect of the device. The installation direction of the one-way valve 34 is not limited to that shown in the figure, and can be aligned with the lower end opening of the connecting sleeve 21, so as to directly lubricate the main shaft position.

[0040] See also Figure 6 A buffer groove 40 is provided inside the longitudinal rectangular groove 22 at a position corresponding to the gear 1 37, and a buffer block 41 is slidably connected inside the buffer groove 40. The buffer block 41 and the buffer groove 40 are both designed as "T"-shaped structures, and a spring 3 42 is fixedly connected therebetween. The buffer block 41 cooperates with the spring 3 42 to better increase the meshing of the gear 1 37 and the gear 2 38 with the tooth groove 12, thereby increasing stability.

[0041] See also Figure 5 and 6 The storage tube 30 is designed as an "L"-shaped structure as a whole. Four groups of guide rods 45 are fixedly connected to the end of the storage tube 30 near the opening at the lower end. The outer surfaces of the four groups of guide rods 45 are sleeved with ear plates 44. One end of the ear plate 44 near the opening at the lower end of the storage tube 30 is fixedly connected to a blocking plate 43. A spring 46 is fixedly connected between the ear plate 44 and the storage tube 30. There are two groups of springs 46 near the opening at the lower end of the storage tube 30. When the extrusion plate 33 moves upward along the extrusion cavity 32, the extrusion plate 33 is pressed against the storage tube 30. The lubricant in the storage tube 30 is discharged through the one-way valve 34. At this time, the sealing plate 43 located above the opening of the lower end of the storage tube 30 is kept closed by the pressure of the lubricant and the spring four 46, and the sealing plate 43 located below the opening of the lower end of the storage tube 30 is opened by the negative pressure generated by the upward movement of the extrusion plate 33, so that the lubricant inside the storage tube 30 is replenished into the extrusion cavity 32. The sealing plate 43 plays a similar role to the one-way valve 34 with the cooperation of the spring four 46 and the guide rod 45, ensuring that the lubricant is replenished in time during operation.

[0042] See also Figure 6A cap 304 is threadedly connected to the opening of the upper end of the storage tube 30, and the outer surface of the lower end of the cap 304 contacts a spring 2 305. The outer surface of the lower end of the spring 2 305 is fixedly connected to a rotating plate 303. The outer surface of the lower end of the rotating plate 303 is rotatably connected to a resisting plate 302 via a rotating shaft. The resisting plate 302 can squeeze the lubricant inside the storage tube 30 in real time under the elastic force generated by the spring 2 305, thereby increasing the stability of lubricant replenishment.

[0043] See also Figure 5 and 6 The outer surface of the resisting plate 302 is penetrated with a second through hole 307, the outer surface of the rotating plate 303 is penetrated with a first through hole 306, the aperture of the first through hole 306 is consistent with that of the second through hole 307, the inner surface of the storage tube 30 is fixedly connected with a guide piece 301, the resisting plate 302 and the guide piece 301 are provided with a guide opening 309 at corresponding positions, the resisting plate 302 is embedded in the outer surface of the guide piece 301 through the guide opening 309, the annular outer surface of the rotating plate 303 is provided with a notch 308 at corresponding positions of the guide piece 301, the notch 308 is aligned with the guide opening 309, after the user adds lubricant to the inside of the storage tube 30, the user aligns the through hole 1 306 on the surface of the rotating plate 303 with the resisting plate 301, and the notch 308 is aligned with the guide opening 309. The through hole 307 on the surface of the plate 302 is aligned, and the guide port 309 is aligned with the guide plate 301 and pressed downward until lubricant overflows from the through hole 1 306 and the through hole 2 307, indicating that there is no air between the lubricant inside the storage tube 30 and the resisting plate 302. Then, the spring 2 305 is rotated, and the angle of the rotating plate 303 is changed through the torsional stiffness of the spring 2 305 so that the through hole 1 306 and the through hole 2 307 are misaligned, and the resistance plate 302 and the rotating plate 303 are kept sealed. Finally, the cap 304 is covered, and the cap 304 compresses the spring 2 305 to ensure that the lubricant inside the storage tube 30 has a certain pressure at all times, and the elastic force generated by the spring 2 305 is smaller than the elastic force generated by the multiple groups of springs 46.

[0044] Example 2: Please refer to Figure 2 , 3and 8. The annular outer surface of the push rod 11 is also provided with a rotary slide groove 13. A connecting ring 14 is fixedly connected to the position of the inner surface of the connecting sleeve 21 near the upper end. A rotary slider 15 is fixedly connected to the annular inner surface of the connecting ring 14 at a position corresponding to the rotary slide groove 13. The lower end edge of the push rod 11 is an inclined structure, and a gasket is fixedly connected to its end to facilitate the flow of lubricant. This embodiment is best used in combination with the first embodiment. When the push rod 11 moves slowly toward the impeller, the push rod 11 is restricted by the hydraulic cylinder 1 to make a linear motion. The rotary slide groove 13 is synchronized with the push rod 11, forcing the rotary slider 15 to drive the connecting sleeve 21 to rotate through the connecting ring 14, so that the lubricant in the opening area at the lower end of the connecting sleeve 21 rolls along the opening of the connecting sleeve 21, moistening the shaft hole and the main shaft of the impeller, further improving the lubricating effect of the lubricant on the impeller.

[0045] See also Fig. 9 A transmission chamber 24 is provided inside the horizontal part of the connecting sleeve 21, and a driving member 25 and a driven member 26 are rotatably connected inside the transmission chamber 24. The driving member 25 and the driven member 26 are meshed with each other. The driving member 25 includes a lower gear 254, and the lower gear 254 is rotatably connected to the transmission chamber 24 through a rotating shaft.

The transmission chamber 24 is connected to the lateral moment A traction groove 271 is opened between the shaped grooves 23, and the traction rope 27 is located inside the traction groove 271. The driving member 25 and the driven member 26 have the same structure and are symmetrically distributed with the axis of the transmission cavity 24. Through the above structure, the two groups of positioning blocks 28 slide along the limiting groove 29, and the displacement of one group of sliding is transmitted to the driving member 25 through the traction rope 27 to force the driven member 26 engaged therewith to rotate accordingly, so that the other group of positioning blocks 28 maintains a synchronous displacement with the one group of positioning blocks 28 under the action of the spring 283, and the traction force generated by the deformation of the coil spring 251 and the spring 283 is in opposite directions, thereby ensuring that the traction rope 27 is always in a taut state, thereby increasing the stability of the structure.

[0046] See also Fig.10 and 11The transmission cavity 24 and the lower gear 254 are fixedly connected with an elastic card plate at the corresponding position, which increases the difficulty of rotating the driving member 25 and further increases the stability of the positioning block 28 inside the transverse rectangular groove 23. A limiting groove 29 corresponding to the positioning block 28 is opened inside the transverse rectangular groove 23. A plug hole 281 is opened through the surface of the positioning block 28, and a socket 282 is inserted into the socket 281. The socket 282 can be switched according to the size of the impeller auxiliary hole, so that the mechanism can adapt to more impeller disassembly.
