Description

Technical Field

[0001] The utility model relates to the technical field of motor rotors, in particular to an energy-saving motor rotor core fixing tool. Background Art

[0002] The motor rotor is a vital component of the motor. It is like the "power core" of the motor. After power is applied, it interacts with the stator to generate rotational force. The rotor is usually composed of an iron core and windings, and its design and quality directly affect the performance of the motor. A high-quality rotor can ensure that the motor runs efficiently and stably, and outputs strong and continuous power. In various industrial equipment and household appliances, the motor rotor silently plays a key role.

[0003] The utility model with announcement number CN220586134U discloses a motor rotor core fixing fixture, including a base, wherein four corners of the upper end of the base are fixedly connected to supporting threaded columns, two supporting threaded columns are slidably connected to the outer sides of connecting plates, the outer upper ends of the supporting threaded columns are spirally connected to nuts, and the centers of the two connecting plates are fixedly connected to fixing plates, the upper ends of the fixing plates are slidably connected to sliding plates, and the inner rear end of the sliding plates is fixedly connected to a first Velcro strap. This motor rotor core fixing fixture, through the set fixing plates, sliding plates, supporting threaded columns and rotor core, when the rotor core is assembled into the casing, is fixed to the inside by the fixing fixture formed by the fine-adjustable and fixed fixing plates, so that the rotor core is located at the center of the stator core of the base when inserted, thereby effectively improving the positioning accuracy of the rotor core body and improving the subsequent assembly accuracy of the rotor core body.

[0004] Similar to the above application, there are still the following shortcomings: looseness may occur when the rotor core is clamped. Utility Model Content

[0005] The utility model discloses an energy-saving motor rotor iron core fixing tool, which aims to solve the technical problem of looseness when the rotor iron core is clamped.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A tool for fixing an energy-saving motor rotor core, comprising a track bar, a sliding rod being slidably connected to the inner cavity of the track bar, a first support rod being fixedly connected to the side of the sliding rod extending to the outer surface of the track bar, a clamping mechanism being fixedly connected to an end of the first support rod away from the sliding rod, the clamping mechanism comprising a track box, the track box being fixedly connected to an end of the first support rod away from the sliding rod, a limiting frame being fixedly connected to the upper surface of the track box, a sliding block being slidably connected to the inner cavity of the limiting frame, a second support rod being fixedly connected to the upper surface of the sliding block, and a clamping plate being fixedly connected to the top end of the second support rod.

[0008] By setting the track bar, the sliding rod can be limited so that the clamping mechanisms at both ends can produce a relative movement effect, so that the clamping mechanism can clamp the motor rotor. By setting the clamping mechanism, the motor rotor core to be installed can be clamped and can be tightly in contact with the inner cavity of the rotor, thereby completing the clamping work of the motor rotor.

[0009] In a preferred solution, the number of the track bars is two, the number of the sliding rods is four, and the four sliding rods are all slidably connected in the inner cavity of the track bar, a connecting rod is provided on one side of the sliding rod extending to the outer surface of the track bar, an extrusion block is fixedly connected to the middle part of the lower surface of the connecting rod, and a spring is fixedly connected between the opposite surfaces of the extrusion block.

[0010] By setting two track bars, the sliding rod can be limited so that the sliding rod can slide stably. By setting an extrusion block and a spring, the connecting rods at both ends can always be subjected to a pulling force, so that the clamping mechanisms at both ends can be relatively close.

[0011] In a preferred solution, the end of the sliding block is fixedly connected with an anti-skid plate, the anti-skid plate is made of rubber material, the outer side of the clamping plate is fixedly connected with a gasket, the gasket is made of softer silicone material, the side of the sliding block away from the anti-skid plate is fixedly connected with a fixed plate, the outer side of the fixed plate is fixedly connected with a sliding plate, the sliding plate is slidably connected to the inner cavity of the track box, the lower surface of the track box is fixedly connected with a support plate, the end of the support plate is fixedly connected with a hydraulic press, the output end of the hydraulic press is fixedly connected with a moving rod, the end of the moving rod is fixedly connected with a moving block, the upper surface of the moving block is fixedly connected with a connecting frame, and the connecting frame is fixedly connected to the lower surface of the end of the sliding plate.

[0012] By setting up an anti-skid plate, it can rub against the inner wall of the motor rotor and increase the friction force. By setting up a gasket, the clamping plate can be prevented from damaging the rotor when the clamping plate is squeezed against the outer surface of the motor rotor. By setting up a track box, the sliding plate can be limited so that the sliding plate can rotate stably in the inner cavity of the track box. By setting up a hydraulic press, after connecting to the power supply and turning on the switch of the hydraulic press, the moving rod can drive the moving block at the end to move.

[0013] As can be seen from the above, an energy-saving motor rotor core fixing fixture has the following improvements and advantages compared with the prior art:

[0014] First, by setting the track bar, the sliding rod can be limited, so that the clamping mechanisms at both ends can produce a relative movement effect, so that the clamping mechanism clamps the motor rotor.

[0015] Secondly, by providing a clamping mechanism, the motor rotor core to be installed can be clamped and can be tightly contacted with the inner cavity of the rotor, thereby completing the clamping work of the motor rotor. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the track bar 1, the sliding rod 2 can be limited, so that the clamping mechanisms 7 at both ends can produce a relative movement effect, so that the clamping mechanism 7 clamps the motor rotor, and the first support rod 6 is fixedly connected to the clamping mechanism 7 at one end away from the sliding rod 2, and the clamping mechanism 7 includes a track box 71 The track box 71 is fixedly connected to the end of the first support rod 6 away from the sliding rod 2, the upper surface of the track box 71 is fixedly connected to the limit frame 72, the inner cavity of the limit frame 72 is slidably connected with a sliding block 73, the upper surface of the sliding block 73 is fixedly connected to the second support rod 74, and the top of the second support rod 74 is fixedly connected with a clamping plate 75. By setting the clamping mechanism 7, the motor rotor core to be installed can be clamped and can be tightly contacted with the inner cavity of the rotor, thereby completing the clamping work of the motor rotor.

[0026] Reference Figure 1 and Figure 2In a preferred embodiment, the number of the track bars 1 is two, the number of the sliding rods 2 is four, and the four sliding rods 2 are all slidably connected to the inner cavity of the track bar 1. By setting two track bars 1, the sliding rod 2 can be limited, so that the sliding rod 2 can slide stably. A connecting rod 3 is provided on one side of the sliding rod 2 extending to the outer surface of the track bar 1, and an extrusion block 4 is fixedly connected to the middle of the lower surface of the connecting rod 3. A spring 5 is fixedly connected between the opposite surfaces of the extrusion block 4. By setting the extrusion block 4 and the spring 5, the connecting rods 3 at both ends can always be subjected to a pulling force, so that the clamping mechanisms 7 at both ends can be relatively close.

By setting the anti-skid plate 714, it can rub against the inner wall of the motor rotor and increase the friction force. The outer side of the clamping plate 75 is fixedly connected to a gasket 76, and the gasket 76 is made of a softer silicone material. By setting the gasket 76, when the clamping plate 75 is squeezed with the outer surface of the motor rotor, it can prevent the clamping plate 75 from damaging the rotor.

The output end of the hydraulic press 710 is fixedly connected with a moving rod 711, and the end of the moving rod 711 is fixedly connected with a moving block 712. The upper surface of the moving block 712 is fixedly connected with a connecting frame 713, and the connecting frame 713 is fixedly connected to the lower surface of the end of the sliding plate 78. By setting the hydraulic press 710, after connecting to the power supply and turning on the switch of the hydraulic press 710, the moving rod 711 can drive the moving block 712 at the end to move.

[0028] Working principle: When in use, the operator places the motor rotor between the two clamping mechanisms 7, and then releases the clamping mechanisms 7. Under the elastic potential energy of the spring 5, the two clamping mechanisms 7 are relatively close. Then the operator connects the hydraulic press 710 to the power supply and turns on the switch of the hydraulic press 710, so that the moving rod 711 drives the moving block 712 to move, and then the sliding plate 78 moves. When moving, the anti-slip plate 714 is inserted into the inner cavity of the motor rotor, and the clamping plate 75 and the washer 76 squeeze the outer surface of the rotor, thereby completing the clamping of the motor rotor.
