Description

Technical Field

[0001] This invention relates to the field of fire pump impeller processing technology, and specifically to a fire pump impeller processing straightening and shaping device. Background Technology

[0002] The fire pump impeller is the core component of the pump body, and its rotation enables water flow. Existing impellers generally include a front cover, a rear cover, and several blades distributed circumferentially between the front and rear covers. These components are integrally formed using a casting process, creating a water flow channel between any two adjacent impellers. While this conventional impeller meets actual production needs, the integral casting process inevitably introduces some deviations, posing a risk over long-term use. To ensure its service life, precision must be maintained during manufacturing to maximize its lifespan. Therefore, impeller straightening and shaping are essential. However, existing straightening devices straighten and shape the impeller blades individually, which is prone to errors and has low straightening efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a fire pump impeller machining straightening and shaping device to solve the technical problems mentioned above.

[0004] The objective of this invention can be achieved through the following technical solutions:

The power gears are respectively meshed with the outer gear tooth and the inner gear tooth. A plurality of power motors are arranged in a circular array on the landing gear, and the output end of the power motors is connected to the power gears.

[0007] As a further aspect of the present invention: a lower ball groove is provided on the inner side of the lifting seat, and a supporting ball is provided in the lower ball groove; a supporting slider is provided on the outer side of the outer straightening and shaping seat; an upper ball groove is provided below the supporting slider; and the upper part of the supporting ball rolls in contact with the upper ball groove.

[0008] As a further embodiment of the present invention: the fixing component includes a fixed base fixedly disposed on the operating table, the fixed base having a plurality of supporting grooves arranged in a circular array, a rotating seat rotatably disposed inside the fixed base, the rotating seat having a plurality of limiting grooves arranged in a circular array, a supporting slider slidably disposed in the supporting groove, a fixed supporting block being disposed on one end of the supporting slider located outside the fixed base, and the other end of the supporting slider located inside the fixed base being slidably disposed in the limiting groove.

[0009] As a further aspect of the present invention: a rotating groove is provided on the outer side of the rotating seat, and a rotating rail is provided on the inner side of the fixed seat and is slidably disposed within the rotating groove.

[0010] As a further aspect of the present invention: a fixed motor is provided below the operating table, and the output end of the fixed motor is fixedly connected to the rotating base.

[0011] As a further aspect of the present invention: lifting cylinders are symmetrically arranged above the fuselage, and the extended end of the lifting cylinders is fixedly connected to the landing gear.

[0012] As a further aspect of the present invention: support frames are symmetrically arranged on both sides of the fuselage, and support slide rails are arranged on the opposite side of the two support frames. Support connecting blocks are symmetrically arranged on both sides of the landing gear, and the support connecting blocks are slidably connected to the support slide rails.

[0013] The beneficial effects of this invention are:

[0014] (1) In this invention, the power motor drives the power gear to rotate. At this time, the outer straightening and shaping seat and the inner straightening and shaping seat that are meshed with the power motor move relative to each other. At this time, each set of outer straightening and shaping molds and inner straightening and shaping molds move relative to each other and then close and align. At this time, the outer mold groove and the inner mold groove act on the blades of the fire pump impeller respectively, thereby straightening and shaping the blades on the fire pump impeller. At the same time, all blades on the fire pump impeller are straightened and shaped at one time, which greatly improves the efficiency of straightening and shaping. At the same time, it avoids the problem of front and rear straightening deviation in the existing single blade straightening and shaping process.

[0015] (2) In this invention, the rotating seat is driven to rotate by a fixed motor. At this time, the limiting groove on the rotating seat acts on the supporting slider. At the same time, in conjunction with the limiting of the supporting groove on the fixed seat, the supporting slider can be controlled to move linearly in the supporting groove. After the fire pump impeller is placed on the fixed seat, the rotating seat is driven to rotate by the fixed motor, and then the supporting slider is controlled to move outward. At this time, the fire pump impeller can be supported by the fixed supporting block. The supporting speed is fast and it is fixed from the inside of the shaft hole of the fire pump impeller, which ensures better correction and shaping of the fire pump impeller blades.

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1 - Figure 8As shown, this invention is a fire pump impeller machining straightening and shaping device, including a machine body 1, an operating platform 2 on the machine body 1, and a fixing component 3 on the operating platform 2 to fix the fire pump impeller to be straightened and shaped. Then, a lifting frame 4 is slidably arranged on the machine body 1 above the operating platform 2, and a lifting seat 5 is arranged below the lifting frame 4. An outer straightening and shaping seat 6 is rotatably arranged inside the lifting seat 5. Several outer straightening and shaping molds 62 are arranged in a circular array below the outer straightening and shaping seat 6. An outer mold groove 620 is opened on one side of the outer straightening and shaping mold 62. Finally, a suspension shaft 73 is arranged on the lifting frame 4, and an inner straightening and shaping seat 7 is rotatably arranged at the end of the suspension shaft 73 located inside the lifting seat 5. The inner straightening and shaping seat 7 is located inside the outer straightening and shaping seat 6. Several inner straightening and shaping molds 72 are arranged in a circular array below the inner straightening and shaping seat 7. The positive shaping mold 72 has an inner mold groove 720 on one side. When the outer mold groove 620 and the inner mold groove 720 are aligned, they form the blade grooves of the fire pump impeller. When the fire pump impeller is corrected and shaped, it is fixed by the fixing component 3. Then, the lifting seat 5 is controlled to move downward by the lifting frame 4. After the lifting seat 5 is aligned with the fixing component 3, the outer correcting and shaping seat 6 and the inner correcting and shaping seat 7 rotate simultaneously. At this time, all the blades on the fire pump impeller can be tightened, corrected and shaped by the outer correcting and shaping mold 62 and the inner correcting and shaping mold 72. During the correction and shaping process, the blades on the fire pump impeller can be corrected and shaped simultaneously, which greatly improves the efficiency of correction and shaping and solves the problem that the blades on the fire pump impeller have a deviation angle during the existing correction and shaping process, which affects the rotation balance of the fire pump impeller.

[0028] Specifically, refer to Figure 1 and Figure 2 As shown, outer gear teeth 61 are arranged in a circular array on the inner side of the outer straightening and shaping seat 6, and inner gear teeth 71 are arranged in a circular array on the outer side of the inner straightening and shaping seat 7. Then, several drive gears 8 are rotatably arranged in a circular array between the outer straightening and shaping seat 6 and the inner straightening and shaping seat 7, and the drive gears 8 are respectively meshed with the outer gear teeth 61 and the inner gear teeth 71. At the same time, several drive motors 81 are arranged in a circular array on the landing gear 4, and the output end of each drive motor 81 is connected to the drive gear 8. The drive motor 81 drives the drive gear 8 to rotate. At this time, the drive gear 8 rotates. The outer straightening and shaping seat 6 and the inner straightening and shaping seat 7, which are engaged with the machine 81, move relative to each other. At this time, each set of outer straightening and shaping molds 62 and inner straightening and shaping molds 72 moves relative to each other and then closes and aligns. Then, the outer mold groove 620 and the inner mold groove 720 act on the blades of the fire pump impeller, thereby straightening and shaping the blades on the fire pump impeller. At the same time, all blades on the fire pump impeller are straightened and shaped at one time, which greatly improves the efficiency of straightening and shaping. At the same time, it avoids the problem of front and rear straightening deviation in the existing single blade straightening and shaping process.

[0029] Reference Figure 4 As shown, a lower ball groove 50 is opened on the inner side of the lifting seat 5, and a support ball 51 is set in the lower ball groove 50. A support slider 63 is set on the outer side of the outer straightening and shaping seat 6. An upper ball groove 630 is opened below the support slider 63. At the same time, the upper part of the support ball 51 rolls in contact with the upper ball groove 630. The outer straightening and shaping seat 6 and the lifting seat 5 are connected by rotation. At the same time, the support ball 51 is used for support, which ensures the stability of the outer straightening and shaping seat 6 during rotation and reduces the friction between the outer straightening and shaping seat 6 and the lifting seat 5.

[0030] Regarding the structure of fixed component 3 Figure 5 , Figure 6 and Figure 7 As shown, the fixing component 3 includes a fixing base 31 fixedly mounted on the operating table 2. The fixing base 31 has several tensioning grooves 310 arranged in a circular array. A rotating base 32 is rotatably mounted inside the fixing base 31. The rotating base 32 has several limiting grooves 321 arranged in a circular array. A tensioning slider 331 is slidably mounted within the tensioning grooves 310. A fixing tensioning block 33 is mounted on the end of the tensioning slider 331 located outside the fixing base 31, and the end of the tensioning slider 331 located inside the fixing base 31 is slidably mounted within the limiting grooves 321. Simultaneously, a fixing motor 30 is mounted below the operating table 2. The output end of the fixing motor 30 is then connected to the rotating base 32... The fixed connection is achieved by driving the rotating seat 32 to rotate via the fixed motor 30. At this time, the limiting groove 321 on the rotating seat 32 acts on the supporting slider 331. Simultaneously, in conjunction with the limiting of the supporting groove 310 on the fixed seat 31, the supporting slider 331 can be controlled to move linearly within the supporting groove 310. After the fire pump impeller is placed on the fixed seat 31, the fixed motor 30 drives the rotating seat 32 to rotate, and then controls the supporting slider 331 to move outward. At this time, the fire pump impeller can be supported by the fixed supporting block 33. The supporting speed is fast, and it is fixed from the inside of the shaft hole of the fire pump impeller, ensuring better correction and shaping of the fire pump impeller blades.

[0031] In addition, a rotating groove 320 is provided on the outer side of the rotating seat 32, and a rotating rail 311 is provided on the inner side of the fixed seat 31 and is slidably disposed in the rotating groove 320 to ensure the stability of the rotation of the rotating seat 32.

[0032] Finally, refer to Figure 8As shown, lifting cylinders 41 are symmetrically arranged above the fuselage 1. The extended end of the lifting cylinder 41 is fixedly connected to the landing gear 4. The lifting cylinder 41 controls the lifting and lowering of the landing gear 4. In order to ensure the stability of the lifting and lowering of the landing gear 4, support frames 42 are symmetrically arranged on both sides of the fuselage 1. Support rails 421 are respectively arranged on the opposite side of the two support frames 42. Then, support connecting blocks 43 are symmetrically arranged on both sides of the landing gear 4. The support connecting blocks 43 are slidably connected to the support rails 421. While the landing gear 4 is lifting and lowering, the support connecting blocks 43 move up and down along the support rails 421, which effectively ensures the stability of the landing gear 4 during the lifting and lowering process.

[0033] Working principle of the invention:

[0034] When straightening and shaping the fire pump impeller, first place the fire pump impeller on the fixed seat 31 in the fixed component 3 on the operating table 2. Then, the fixed motor 30 drives the rotating seat 32 to rotate. At this time, the limiting slide groove 321 on the rotating seat 32 acts on the supporting slide 331. At the same time, in conjunction with the limiting of the supporting slide groove 310 on the fixed seat 31, the supporting slide 331 can be controlled to move outward in the supporting slide groove 310, thereby fixing the fire pump impeller placed on the rotating seat 32.

[0035] After the fire pump impeller is fixed, the lifting cylinder 41 controls the landing gear 4 to move downward. At the same time, the support connecting block 43 moves downward along the support slide rail 421 to ensure the stability of the landing gear 4 during the lifting process.

[0036] When the landing gear 4 descends to the designated position, that is, after the lifting seat 5 is aligned with the fixed seat 31, each set of outer straightening and shaping molds 62 and inner straightening and shaping molds 72 are located on both sides of each fire pump impeller blade. At this time, the power motor 81 drives the power gear 8 to rotate, and the outer straightening and shaping seat 6 and the inner straightening and shaping seat 7, which are meshed with the power motor 81, move relative to each other. At this time, each set of outer straightening and shaping molds 62 and inner straightening and shaping molds 72 move relative to each other and then close and align. Then, the outer mold groove 620 and the inner mold groove 720 act on the fire pump impeller blades respectively, so that the blades on the fire pump impeller can be straightened and shaped.

[0037] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
