Description
Technical Field
[0001] The utility model relates to the technical field of detecting concentricity and processing stator and rotor slots, in particular to a tool for detecting concentricity and processing high points in stator and rotor slots. Background Art
[0002] Stator and rotor laminations are common components in equipment such as motors and generators. They are the combination or design of stators and rotors, especially in terms of the layout of coils or poles and the structure of laminations. During the manufacturing process, it is crucial to ensure the correct assembly and electrical insulation of the laminations to ensure the performance and safety of the equipment. In motors and generators, they affect the efficiency and operational reliability of the equipment. During design and manufacturing, special attention must be paid to their assembly quality and insulation performance to meet the electrical and mechanical requirements of the equipment. The quality of the stator and rotor lamination process affects the accuracy of the stator and will cause eccentric bore sweeping during motor operation. If there are high points in the stator and rotor slots, the insulation of the motor will fail. Therefore, they need to be tested before leaving the factory.
[0003] Traditionally, the tooling for detecting concentricity and dealing with high points in the stator and rotor slots is mainly done by manual visual inspection, assisted by a simple ruler to confirm verticality. Workers will use their naked eyes to check the alignment and surface quality of the rotor and stator slots, and observe the contact points and gaps between the rotor and stator to determine whether there are deviations or high points. The ruler can then be used to check the verticality of the stator slots to ensure that the rotor can be correctly installed and rotated.
[0004] However, the traditional tooling for detecting concentricity and processing high points in the stator and rotor slots can only detect defective products with large concentricity deviations. Products with concentricity deviations less than 1mm, or even required to have a concentricity deviation less than 0.05mm, cannot be visually judged by the naked eye. In addition, it is impossible to detect whether there are high points in the stator and rotor slots, which will damage the insulation layer of the motor and cause poor insulation to the ground. Therefore, a tooling for detecting concentricity and processing high points in the stator and rotor slots is proposed to solve the above problems. Utility Model Content
[0005] In order to make up for the above shortcomings, the utility model provides a tooling for detecting concentricity and processing high points in the stator and rotor slots, aiming to improve the problems in the prior art where the visual inspection time is too long, and products with small deviations cannot be accurately detected, and there are also risks such as bore scraping caused by concentricity differences during motor operation.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A tool for detecting concentricity and processing high points in the slots of stators and rotors, comprising a push rod, a detection disk is arranged on the outer wall of the push rod, a placement hole is opened inside the detection disk, the outer wall of the push rod is slidably connected to the inside of the placement hole, a grooved knife is fixedly connected to the outer wall of the detection disk, and a force-bearing component is arranged on the top of the push rod, and the force-bearing component acts on the push rod to bear force;
[0008] As a further description of the above technical solution:
[0009] The force-bearing component includes a force-bearing plate, the bottom of which is fixedly connected to the top of the push rod;
[0010] As a further description of the above technical solution:
[0011] A slot is provided inside the detection plate, and a threaded column is rotatably connected inside the push rod;
[0012] As a further description of the above technical solution:
[0013] The bottom of the threaded column is fixedly connected with a knob, and the outer wall of the threaded column is threadedly connected with a tapered block;
[0014] As a further description of the above technical solution:
[0015] A fixing column is slidably connected inside the conical block, and both ends of the fixing column are fixedly connected inside the push rod;
[0016] As a further description of the above technical solution:
[0017] A limiting groove is provided inside the push rod, a clamping block is provided inside the push rod, and an outer wall of the clamping block is slidably connected to the limiting groove;
[0018] As a further description of the above technical solution:
[0019] The outer wall of the clamping block is slidably connected to the inside of the clamping slot, the outer wall of the clamping block is fixedly connected to a slider, and the outer wall of the slider is slidably connected to the inside of the limiting slot;
[0020] As a further description of the above technical solution:
[0021] The outer wall of the clamping block is rotatably connected to a rotating wheel, and the outer wall of the rotating wheel is rotatably connected to the outer wall of the conical block.
[0022] The utility model has the following beneficial effects:
[0023] 1. In the utility model, the stator and rotor laminations realize their detection function by moving the push rod. When the push rod is placed, the detection disk, the groove knife and the placement hole and other structures will be linked accordingly to realize the detection of the stator and rotor laminations, and to detect them conveniently. The high points in the grooves can be detected and discharged, which solves the problem that it is impossible to accurately detect them and cannot discharge the internal high points, and improves the rotor accuracy.
[0024] 2. In the utility model, the clamping block realizes its moving function by turning the knob. When the knob is turned, structures such as the threaded column, the fixed column and the slider will be linked accordingly to realize the fixed replacement of the detection disk. Different stator and rotor laminations may have different sizes, shapes or configurations. The detection disk can be replaced conveniently and can quickly adapt to different types of stator and rotor combinations without additional tools or complicated operations. This solves the problem of not being able to quickly replace the detection according to the corresponding stator and rotor laminations, and improves the applicability of the device.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1The utility model provides an embodiment: a tool for detecting concentricity and processing high points in stator and rotor slots, including a push rod 1, a detection disk 4 is provided on the outer wall of the push rod 1, a placement hole 5 is opened inside the detection disk 4, the outer wall of the push rod 1 is slidably connected to the placement hole 5, a grooved knife 3 is fixedly connected to the outer wall of the detection disk 4, and a force-bearing component is provided on the top of the push rod 1, which acts on the push rod 1 to bear force.
[0032] Specifically, by moving the push rod 1, the detection disk 4 is driven to move, and then the detection disk 4 drives the groove knife 3 to move to detect the stator and rotor laminations, so that the detection and adjustment of the stator and rotor laminations become efficient and accurate. At the same time, the tooling can reduce the time for judging whether there is a problem with the device, and the operation of the entire tooling is as simple and intuitive as possible, reducing the training requirements of operators and the possibility of operating errors. While detecting the concentricity, the high points in the slot can also be detected and eliminated to prevent them from causing insulation failure of the motor.
[0033] Reference Figure 1-Figure 2 The force-bearing component includes a force-bearing plate 2, and the bottom of the force-bearing plate 2 is fixedly connected to the top of the push rod 1.
[0034] Specifically, when discharging the high point in the groove, a hammer is needed to knock the push rod 1, but the push rod 1 has fewer stress points, so the force plate 2 is used to increase the area and strength of the stress points, thereby improving the stability and reliability of the tooling system and extending the service life of the push rod.
[0035] Reference Figure 1-Figure 3 A card slot 11 is provided inside the detection disk 4, a threaded column 7 is rotatably connected inside the push rod 1, a knob 12 is fixedly connected to the bottom of the threaded column 7, a conical block 9 is threadedly connected to the outer wall of the threaded column 7, a fixed column 6 is slidably connected inside the conical block 9, both ends of the fixed column 6 are fixedly connected to the inside of the push rod 1, a limiting groove 10 is provided inside the push rod 1, a card block 8 is provided inside the push rod 1, the outer wall of the card block 8 is slidably connected to the inside of the limiting groove 10, the outer wall of the card block 8 is slidably connected to the inside of the card slot 11, a slider 13 is fixedly connected to the outer wall of the card block 8, the outer wall of the slider 13 is slidably connected to the inside of the limiting groove 10, the outer wall of the card block 8 is rotatably connected to a rotating wheel 14, and the outer wall of the rotating wheel 14 is rotatably connected to the outer wall of the conical block 9.
[0036] Specifically, the knob 12 is turned to drive the threaded column 7 to rotate, and then the threaded column 7 drives the conical block 9 to rise and fall. Then, because the surface of the block 8 is an inclined surface, it can be directly taken out and then placed in the corresponding detection disk 4. Then, the knob 12 is turned again to drive the threaded column 7 to rotate, so that the conical block 9 is raised and lowered. Then, because the conical block 9 is conical, the block 8 is pushed to move to the inside of the card slot 11 for fixation, so that the detection disk 4 can be easily replaced, which can significantly shorten the setting and preparation time and improve production efficiency. At the same time, using a good replaceable detection disk can ensure that consistent testing and inspection standards are maintained between different stator and rotor laminations, which helps to improve product quality and process stability. In the modern manufacturing environment, products change rapidly and customer needs are diverse. The detection disk 4 can be easily replaced, so that manufacturers can quickly respond to changes in market demand and flexibly respond to different stator and rotor lamination requirements.
[0037] Working principle: before inspecting the stator and rotor laminations, first select the corresponding inspection disk 4, then put the push rod 1 into the placement hole 5 opened on the inspection disk 4, then turn the knob 12, and drive the fixedly connected threaded column 7 to rotate through the knob 12, and then drive the threaded conical block 9 to slide on the outer wall of the fixed column 6 to which it is slidably connected through the threaded column 7, and then drive the slidingly connected rotating wheel 14 to move through the conical block 9, and then drive the rotatingly connected card block 8 to move through the rotating wheel 14, and at the same time drive the fixedly connected slider 13 to slide on the outer wall of the sliding connection through the card block 8. The push rod 1 is moved to move the detection disk 4 through the push rod 1, and the stator and rotor laminations are placed inside. The push rod 1 is lifted and lowered, and the detection disk 4 is lifted and lowered through the push rod 1, and the fixedly connected grooved knife 3 is lifted and lowered through the detection disk 4. When a high point appears inside, a hammer is used to knock the force plate 2, so that it can be taken out through the grooved knife 3, and the stator and rotor laminations are inspected and problems are solved.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
