Description

Technical Field

[0001] This utility model relates to the field of water pump motor repair technology, specifically to an anti-deviation fixing structure for water pump motor repair. Background Technology

[0002] In industrial production and water supply systems, water pump motors are critical power equipment, and their operational stability directly affects system efficiency and reliability. However, due to factors such as long-term high-load operation, vibration and shock, or media corrosion, motor bearing wear and seal failure occur frequently, requiring frequent disassembly and repair. In traditional maintenance work, motor fixing often relies on simple tooling or temporary on-site welded brackets.

[0003] Currently, in the maintenance of water pump motors, traditional fixing methods typically involve simple bolt tightening or welding of temporary brackets. These methods suffer from low positioning accuracy and difficulty in adjustment. Due to the large weight of the motor and the frequent disassembly and assembly of precision components such as couplings and bearings during maintenance, existing methods can easily lead to axial or radial displacement of the motor during operation, affecting maintenance efficiency and even causing assembly errors. Furthermore, maintenance conditions often require fine-tuning of the motor angle or height according to disassembly requirements. Existing technologies lack quick adjustment functions for brackets, forcing operators to repeatedly tighten and loosen bolts or manually align the motor using shims. This is not only time-consuming and labor-intensive but may also pose safety hazards due to unstable fixing. Utility Model Content

[0008] A gear is sleeved on the mounting shaft, and a rack is slidably mounted inside the mounting bracket, with the rack meshing with the gear. A cylinder is fixedly mounted inside the mounting bracket, and the rack is fixedly connected to the output end of the cylinder piston rod. The positioning mechanism includes four sets of positioning blocks located inside the positioning platform.

[0011] Preferably, the positioning mechanism includes a mounting rod fixedly installed on the positioning platform and a positioning seat located below the positioning platform. Two sets of symmetrically distributed positioning frames are slidably installed in the positioning seat. A bidirectional threaded rod is rotatably installed in the positioning seat. The two ends of the bidirectional threaded rod pass through the two sets of positioning frames and are threadedly connected to the two sets of positioning frames respectively.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an anti-deviation fixing structure for water pump motor maintenance, which has the following beneficial effects:

[0017] Through the coordinated action of four sets of positioning blocks in the positioning mechanism, the water pump motor can be quickly and accurately centered, effectively avoiding the center offset problem caused by uneven bolt tightening or welding deformation in traditional fixing methods. This significantly improves the positioning accuracy and stability during motor maintenance. Simultaneously, the cylinder-driven rack and pinion gear meshing transmission integrated within the mounting bracket allows for flexible control of the overall rotation angle of the positioning platform. This enables operators to quickly and smoothly adjust the motor maintenance angle without repeated disassembly or manual adjustment, greatly enhancing the operational convenience and safety when disassembling and assembling precision components such as couplings and bearings. The coordinated action of the positioning mechanism further enhances this capability. After the motor center positioning is completed, the spacing between the two sets of clamping frames can be flexibly adjusted according to the actual size of the motor base to ensure wide compatibility with different motor models. The screw transmission mechanism in the mounting rod drives the screw tube to rotate synchronously through the sliding fit of the keyway and key block, thereby controlling the extension and retraction of the first push rod and the second push rod respectively, pushing the clamping seat and clamping frame downward to press the motor base, forming a reliable constraint on the vertical direction of the motor. This multi-stage positioning mechanism effectively enhances the overall rigidity of the motor during maintenance, prevents axial or radial movement during operation, and further improves the safety and assembly accuracy of maintenance operations.

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Figures 1-5In one embodiment of this utility model, a non-deviation fixing structure for water pump motor maintenance includes a mounting frame 1 and a positioning platform 2. The positioning platform 2 is equipped with a positioning mechanism 3 and is rotatably connected to the mounting frame 1 via a mounting shaft 306. A locking mechanism 4 is provided on the positioning platform 2. A gear 307 is sleeved on the mounting shaft 306. A rack 308 is slidably mounted inside the mounting frame 1 and meshes with the gear 307. A cylinder 309 is fixedly mounted inside the mounting frame 1, and the rack 308 is fixedly connected to the output end of the piston rod of the cylinder 309. The positioning mechanism 3 includes four sets of components located on the positioning platform 2. The positioning mechanism 3 includes a positioning block 301. Two sets of symmetrically distributed first adjusting rods 302 and two sets of symmetrically distributed second adjusting rods 303 are slidably installed within the positioning platform 2. The two sets of first adjusting rods 302 and two sets of second adjusting rods 303 are vertically distributed. The positioning block 301 is slidably connected to one set of first adjusting rods 302 and one set of second adjusting rods 303 respectively. Through the coordinated action of the four sets of positioning blocks 301 in the positioning mechanism 3, the pump motor can be quickly and accurately positioned at the center, effectively avoiding the center offset problem caused by uneven bolt tightening or welding deformation in traditional fixing methods. This significantly improves the positioning accuracy and stability during motor maintenance. Simultaneously, the cylinder 309 integrated within the mounting bracket 1 drives the rack 308 and gear 307 to mesh, flexibly controlling the overall rotation angle of the positioning platform 2. This allows operators to quickly and smoothly adjust the motor maintenance angle without repeated disassembly or manual adjustment, greatly enhancing the ease of operation and safety when disassembling and assembling precision components such as couplings and bearings. Through the synergistic effect of the clamping mechanism 4, after completing the motor center positioning, the spacing between the two sets of clamping brackets 402 can be flexibly adjusted according to the actual dimensions of the motor base. To ensure broad compatibility with different motor models, the screw 407 transmission mechanism inside the mounting rod 404 drives the screw tube 409 to rotate synchronously through the sliding engagement of the keyway 408 and the key block 410. This, in turn, controls the extension and retraction of the first push rod 405 and the second push rod 406, pushing the locking seat 401 and the locking frame 402 downward to press against the motor base, forming a reliable constraint on the vertical direction of the motor. This multi-level positioning mechanism effectively enhances the overall rigidity of the motor during maintenance, preventing axial or radial movement during operation, and further improving the safety and assembly accuracy of maintenance work.

[0027] In this embodiment, reference Figure 2 , Figure 3As shown, a first bidirectional lead screw 304 is rotatably installed inside the positioning platform 2. Both ends of the first bidirectional lead screw 304 pass through two sets of first adjusting rods 302 and are threadedly connected to the two sets of first adjusting rods 302 respectively. A second bidirectional lead screw 305 is rotatably installed inside the positioning platform 2. Both ends of the second bidirectional lead screw 305 pass through two sets of second adjusting rods 303 and are threadedly connected to the two sets of second adjusting rods 303 respectively. Firstly, the positioning mechanism 3 achieves precise centering and angle adjustment of the water pump motor. Then, the starting cylinder 309 pushes the rack 308 vertically... The linear motion, with the gear 307 meshing with the rack 308, drives the mounting shaft 306 and the positioning table 2 to rotate as a whole, thereby adjusting the motor to the optimal maintenance angle. At the same time, the first and second bidirectional lead screws 305 inside the positioning table 2 are rotated, driving the two sets of first adjusting rods 302 and the two sets of second adjusting rods 303 to move in opposite directions, causing the four sets of positioning blocks 301 to move closer or further away synchronously, clamping the motor housing from four directions, quickly completing the automatic alignment and fixation of its center position, effectively avoiding radial and axial offset during operation.

[0028] In this embodiment, reference Figure 4 and Figure 5As shown, the positioning mechanism 4 includes a mounting rod 404 fixedly mounted on the positioning platform 2, and a positioning seat 401 located below the positioning platform 2. Two sets of symmetrically distributed positioning brackets 402 are slidably mounted inside the positioning seat 401. A bidirectional threaded rod 403 is rotatably mounted inside the positioning seat 401. Both ends of the bidirectional threaded rod 403 pass through the two sets of positioning brackets 402 and are threadedly connected to the two sets of positioning brackets 402 respectively. A first push rod 405 is slidably mounted inside the mounting rod 404, and a second push rod 405 is slidably mounted inside the first push rod 405. The second push rod 406 has one end away from the mounting rod 404, which is fixedly connected to the locking seat 401. A screw 407 is rotatably installed inside the mounting rod 404. A threaded tube 409 is rotatably installed inside the first push rod 405. The lower end of the screw 407 passes through the first push rod 405 and is threadedly connected to it. The lower end of the threaded tube 409 passes through the second push rod 406 and is threadedly connected to it. Two sets of symmetrically distributed keyways 408 are provided on the screw 407, and two sets of symmetrically distributed keyways 408 are provided inside the threaded tube 409. The key block 410 of the cloth, two sets of key blocks 410 and keyways 408 are distributed accordingly, and the screw tube 409 is slidably sleeved with the screw 407 through the key blocks 410 and keyways 408. After the center positioning is completed, the locking mechanism 4 is immediately activated to achieve multi-level reinforcement. According to the size of the motor base, the motor in the locking seat 401 drives the bidirectional threaded rod 403 to rotate, so as to adjust the distance between the two sets of locking frames 402 and align them with the edge of the base. Subsequently, the motor in the drive mounting rod 404 drives the screw 407 to rotate. 7. The rotation, through the cooperation of the keyway 408 and the key block 410, drives the solenoid 409 to rotate synchronously. This transmission process causes the first push rod 405, which is threadedly connected to the screw 407, and the second push rod 406, which is threadedly connected to the solenoid 409, to extend downwards respectively, jointly pushing the locking seat 401 and the locking frame 402 to move downwards until the locking frame 402 firmly presses against the upper surface of the motor base. The pressing force and the lateral clamping force of the positioning mechanism 3 form a three-dimensional constraint, jointly ensuring the absolute stability of the motor in subsequent maintenance operations.

[0029] In this embodiment, the positioning mechanism 3 first achieves precise centering and angle adjustment of the water pump motor. The starting cylinder 309 drives the rack 308 in linear motion. The gear 307 meshing with the rack 308 drives the mounting shaft 306 and the positioning platform 2 to rotate as a whole, thereby adjusting the motor to the optimal maintenance angle. Simultaneously, the first and second bidirectional lead screws 305 inside the positioning platform 2 rotate, driving two sets of first adjusting rods 302 and two sets of second adjusting rods 303 to move in opposite directions, causing the four sets of positioning blocks 301 to move synchronously closer or further away, clamping the motor housing from four directions. This quickly completes the automatic centering and fixing of the motor, effectively preventing radial and axial offset during operation. After center positioning is completed, the clamping mechanism 4 is activated to achieve multi-level reinforcement, according to the electrical... The machine base dimensions are determined by the motor inside the starting mounting bracket 401 driving the bidirectional threaded rod 403 to rotate, thereby adjusting the distance between the two sets of mounting brackets 402 to align them with the edge of the base. Subsequently, the motor inside the driving mounting rod 404 drives the screw 407 to rotate. The rotation of the screw 407, through the cooperation of the keyway 408 and the key block 410, drives the screw tube 409 to rotate synchronously. This transmission process causes the first push rod 405, which is threadedly connected to the screw 407, and the second push rod 406, which is threadedly connected to the screw tube 409, to extend downwards, jointly pushing the mounting bracket 401 and the mounting bracket 402 downwards until the mounting bracket 402 firmly presses against the upper surface of the motor base. The pressing force and the lateral clamping force of the positioning mechanism 3 form a three-dimensional constraint, jointly ensuring the absolute stability of the motor in subsequent maintenance operations.
