Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment motor stator processing, in particular to a stator slot grinding device for sewage treatment motor production. Background Technique

[0002] The motors commonly used in sewage treatment systems include motors for centrifugal pumps, agitators, aerators, etc. The motor for centrifugal pumps is a very common motor in sewage treatment systems. It is mainly used to pump sewage from one place to another, including from the sump to the treatment equipment, from the treatment equipment to the regeneration water tank, etc. The characteristics of this motor are large output power and stable operation, and it can adapt to different requirements such as high pressure, low pressure, and large flow. The agitator motor is also a commonly used motor in sewage treatment systems. The agitator is mainly used to stir the sewage in the mixing tank to promote the mixing reaction therein. The characteristics of this motor are stable operation and large output torque, and it can adapt to the requirements of different loads. The aerator motor is mainly used to provide the power required for the aeration facility to promote the mixing of water and oxygen in the treatment equipment. The characteristics of this motor are small output power but long operation time, and it requires good durability. Regardless of what kind of motor, its main component includes the stator. The motor stator slot grinding machine is a device used to grind the motor stator slot. The stator slot is an important part of the motor, and its shape and accuracy directly affect the performance and efficiency of the motor. The purpose of grinding the stator slot is to remove burrs, impurities, and uneven parts in the slot to ensure the stability and reliability of the motor stator during assembly and operation. The motor stator slot grinding machine usually uses a high-speed rotating grinding wheel or abrasive belt to grind the stator slot, and other grinding tools such as grinding heads and grinding rods can also be used. During the grinding process, it is necessary to control the grinding depth and speed to avoid over-grinding or under-grinding, which will affect the motor performance. However, during the grinding process with traditional tools, limited by the size of the motor stator, only one stator slot can be ground one by one, which is not conducive to improving the overall grinding efficiency.

[0011] Preferably, the transmission gear is meshed with the lifting gear, and the lifting gear is threadedly connected to the displacement rod, and the upper surface of the lifting gear is in contact with the outer surface of one end of the limiting frame.

[0012] Adopting the above technical solution, the lifting gear can remain stable during rotation under the rotational connection with the support seat and the limitation of the limiting frame.

Further, by adjusting the distance between the grinding rods to be adjustable, the grinding rods can gradually increase the grinding amount of the stator slots, so that the inner cavity of the stator slots can be better ground in place, avoiding incomplete grinding caused by a large single grinding amount, which affects the installation of the coil.

[0020] 3. Furthermore, when the chamfer at the lower end of the grinding rod is squeezed, the support rods are elastically deformed, enabling the grinding rod to smoothly enter the stator slots of the motor to achieve the purpose of grinding the stator slots. At the same time, the long sliding stroke and the long setting of the grinding rod also ensure the grinding effect on the inner concave corners of the stator slots. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 , the present utility model provides a technical solution: a stator slot grinding device for the production of sewage treatment motors.

[0030] Embodiment 1

[0031] In this embodiment, it is disclosed that: there is a base 1, a top plate 2 is arranged above the base 1, and a sliding rod 3 and a displacement rod 4 are fixedly arranged on the lower surface of the top plate 2, and the lower ends of the sliding rod 3 and the displacement rod 4 are fixedly connected to the base 1. A support seat 5 is arranged on the outer surfaces of the sliding rod 3 and the displacement rod 4. The support seat 5 is slidably connected to both the sliding rod 3 and the displacement rod 4. The inner surface of the upper section of the support seat 5 is designed with an arc chamfer. A progressive grinding mechanism is arranged on the lower surface of the top plate 2 to ensure the grinding effect and accuracy by gradually increasing the grinding amount;

[0032] The progressive grinding mechanism includes: a central seat 6, the central seat 6 is fixedly arranged on the lower surface of the top plate 2, and an upper displacement ring 7 and a lower displacement ring 8 are arranged on the outer surface of the central seat 6. An extrusion rod 9 is fixedly installed between the side surfaces of the upper displacement ring 7 and the lower displacement ring 8. A rotating support rod 10 is installed on the side surface of the central seat 6, and a grinding rod 11 is fixedly connected to one end of the support rod 10. An adjustment motor 12 is fixedly installed at the upper end of the central seat 6, and an adjustment rod 13 is fixedly connected to the lower end of the output shaft of the adjustment motor 12. A waste slot 14 is opened on the upper surface of the base 1;

[0033] The upper displacement ring 7 and the lower displacement ring 8 are threadedly connected to the adjusting rod 13, and the upper displacement ring 7 and the lower displacement ring 8 are slidably connected to the center seat 6;

[0034] Two adjacent support rods 10 are arranged in a V shape. The outer surface of the middle section of the extrusion rod 9 is provided with a triangular protrusion, and the lower end of the triangular protrusion of the extrusion rod 9 is located between two adjacent support rods 10, and the lower end of the triangular protrusion of the extrusion rod 9 is in contact with the outer surfaces of the two adjacent support rods 10. The lower end of the grinding rod 11 is chamfered;

[0035] During the grinding process, when the stator slot contacts the chamfer at the lower end of the grinding rod 11, the grinding rod 11 is displaced by the extrusion, enabling the grinding rod 11 to enter the inner side of the stator slot. At this time, the grinding rod 11, supported by the support rod 10, grinds the inner concave angle of the stator slot through friction with the inner wall of the stator slot. As the grinding progresses, the adjusting motor 12 at the upper end of the center seat 6 drives the adjusting rod 13 to rotate. The adjusting rod 13 drives the extrusion rod 9 to slide downward through the threaded connection with the upper displacement ring 7 and the lower displacement ring 8. At this time, the extrusion rod 9 presses downward on the outer surfaces of the two support rods 10 through the triangular protrusion, causing the two support rods 10 distributed in a V shape to separate from each other, thereby increasing the distance between two adjacent grinding rods 11 and achieving the purpose of gradually increasing the grinding amount of the inner concave angle of the stator slot inner wall;

[0036] After one grinding is completed, at this time, the adjusting rod 13 drives the extrusion rod 9 to slide upward through the threaded connection with the upper displacement ring 7 and the lower displacement ring 8, reducing the distance between the two grinding rods 11, so that the stator can slide downward under the action of gravity without being tightly fixed.

[0037] Embodiment 2

[0038] This embodiment discloses on the basis of Embodiment 1: A lifting mechanism is provided on one end of the upper surface of the support seat 5 to perform uniform grinding on the stator slot by means of lifting friction;

A rotating lifting gear 17 is installed on one end of the upper surface of the support seat 5, and a limiting frame 18 is fixedly arranged on the upper surface of the support seat 5 on one side of the lifting gear 17;

[0040] The transmission gear 16 is meshed with the lifting gear 17, and the lifting gear 17 is threadedly connected to the displacement rod 4, and the upper surface of the lifting gear 17 is in contact with the outer surface of one end of the limiting frame 18;

[0041] When grinding, first place the stator to be ground inside the support base 5, and then start the lifting motor 15. The lifting motor 15 drives the lifting gear 17 to rotate under the limitation of the limiting frame 18 through the meshing of the transmission gear 16 and the lifting gear 17. The lifting gear 17 drives the support base 5 to move up and down relative to the base 1 and the top plate 2 on the sliding rod 3 through the rotational connection with the support base 5 and the threaded connection with the displacement rod 4, so that the stator slot can contact the grinding rod 11 and be ground, and the waste chips ground down fall into the waste material groove 14 and are collected.
