Description

Technical Field

[0001] The utility model belongs to the technical field of electric mechanism detection, and particularly relates to a general electric mechanism detector. Background Technique

[0002] An electric mechanism is a mechanical transmission system composed of a motor, a reducer, a coupling, a brake, etc. The motor, as the power source, converts electrical energy into mechanical energy, while the reducer plays a role in converting the high-speed rotation of the motor into a low-speed and large-torque output. The coupling is used to connect the motor and the reducer to ensure the continuity and stability of power transmission. The brake is used to stop or decelerate the movement of the electric mechanism when needed.

[0003] The working principle of the electric mechanism is mainly based on the electromagnetic induction principle of the motor and the transmission principle of the reducer. Among them, the rotating components that generate rotational torque inside the electric mechanism are one of the important components to complete the operation. The output torque is transmitted to the load through the transmission shaft to achieve mechanical transmission. Mechanical transmission detection is also crucial. Among them, the rotor dynamic balance test for the electric mechanism can ensure that the rotor will not generate excessive vibration and noise during rotation, which is of great significance for improving the operation stability and reliability of mechanical equipment. However, the current detectors still have the following defects: for power components of different sizes, the binding tension of the detector cannot be adjusted in time, resulting in some pressure on the outer surface of the power component when the tension belt binds the power component. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a general electric mechanism detector, which can adapt to place rotating components of different sizes, and adaptively adjust the tension of the tension belt according to the size of the rotating component, and has a certain rotational margin while fixing the rotating component.

[0005] The technical solution adopted by the utility model is specifically as follows:

[0006] A general electric mechanism detector includes a fixed mounting wheel, an inner fixed ring plate, a tension adjusting component, and a tension belt. The inner ring of the fixed mounting wheel is hollow and used for installing electric mechanism components. The inner fixed ring plate is arranged side by side inside the ring of the fixed mounting wheel, and there is a distance between the two fixed mounting wheels. An adjusting groove is also opened on the surface of the inner fixed ring plate on the side facing the inside of the ring of the fixed mounting wheel. The tension adjusting component is arranged inside the adjusting groove and slides in the adjusting groove to adjust the tension of the electric mechanism components. The end of the tension belt is arranged on the tension adjusting component.

[0007] In a preferred scheme, the opening range of the adjusting groove extends from the bottom of the inner fixed ring plate to both sides and is opened in a superior arc. First springs are installed at both ends of the adjusting groove.

[0008] In a preferred embodiment, a cavity is further inwardly formed on the side of the inner fixing ring plate where the adjusting groove is opened. Ratch teeth are provided on the cavity wall of the cavity. The ratch teeth are distributed on both sides of the cavity wall of the cavity, and the protruding directions of the ratch teeth on both sides are opposite.

[0009] In a preferred embodiment, the tension adjusting assembly includes a smooth shaft body. The end of the tension belt is located on the shaft body. Ring platforms are provided at both ends of the shaft body, and adjusting handles are installed on the end sides of the ring platforms.

[0010] In a preferred embodiment, a cavity is provided inside the ring platform. An adjusting tooth is provided in the cavity. The top of the adjusting tooth abuts against and is stuck in the tooth recess of the ratch tooth. A bottom plate adapted to the cavity is provided at the bottom of the adjusting tooth. A second spring is provided in the cavity. One end of the second spring is fixed to the bottom plate, and the other end is fixed to the cavity wall.

[0011] In a preferred embodiment, a groove is formed at the position of the fixed mounting wheel corresponding to the ratch tooth, and a third spring is installed inside the groove.

[0012] The technical effects achieved by the present utility model are as follows:

[0013] For a general electric mechanism detector of the present utility model, when it is necessary to adjust the tension of the rotating components of the electric mechanism, hold the adjusting handles with both hands and press down or lift. Since the tension belt has a certain elasticity and has a certain margin of movement when pressing on the rotating components, it can rotate while keeping the rotating components fixed, so as to perform dynamic balance testing. Moreover, since the fixed mounting wheel is hollow, it can be adapted to place rotating components of different sizes, and the tension of the tension belt can be adjusted according to the size of the rotating components, or cooperate with the lifting seat.

[0014] For a general electric mechanism detector of the present utility model, the ratch teeth provided on the cavity wall of the cavity make the inner wall of the inner fixing ring plate form the structure of an inner ratchet wheel. Under normal conditions, the adjusting tooth is propped up by the second spring and is always abutted against and stuck in the tooth recess of the ratch tooth. When it is necessary to adjust the position of the tension belt, hold the adjusting handle and press down. The adjusting tooth on the ring platform passes through and is limited and stuck on the ratch tooth in sequence until it is adjusted to the appropriate position, realizing the adaptive adjustment of the tension belt of the detector according to power components of different sizes. And the tension belt has elasticity and has a certain margin of rotation while being able to fix the rotating components. Description of the Drawings

[0027] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be made in conjunction with the drawings of the specification.

[0028] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in a preferred implementation manner" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0030] Next, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0031] As Figures 1-6 shown, a general-purpose electric mechanism detector includes a fixed mounting wheel 1, an inner fixed ring plate 2, a tension adjustment assembly 6, and a tension belt 7. The inner ring of the fixed mounting wheel 1 is hollow and used for installing electric mechanism components. The inner fixed ring plates 2 are arranged side by side inside the ring of the fixed mounting wheel 1, and there is a gap 3 between the two fixed mounting wheels 1. An adjustment groove 4 is also opened on the side of the inner fixed ring plate 2 facing the inside of the ring of the fixed mounting wheel 1. The tension adjustment assembly 6 is arranged inside the adjustment groove 4 and slides in the adjustment groove 4 to adjust the tension on the electric mechanism components. The end of the tension belt 7 is arranged on the tension adjustment assembly 6.

[0032] Among them, the rotating component is one of the important components for the electric mechanism to perform operations smoothly. Place the rotating component on the seat platform, and the rotatable parts at both ends are placed on the roller part of the seat platform. Pull the tension belt 7 to both sides through the tension adjustment assembly 6 so that the rotating component can be rotatably fixed on the seat platform, enabling it to rotate smoothly during the detection process, and testing the dynamic balance ability of the rotating component.

[0033] As Figures 2-3 shown, the opening range of the adjustment groove 4 extends from the bottom of the inner fixed ring plate 2 to both sides and is opened in a superior arc. First springs 5 are installed at both ends of the adjustment groove 4.

[0034] Specifically, when the tension adjustment assembly 6 is in the retracted and relaxed state, the first spring 5 can buffer the tension caused by the tension of the tension belt 7 to prevent the adjuster from being injured by the elastic force of the tension belt 7.

[0035] As Figures 3-4 shown, a cavity 201 is also opened inward on the side of the inner fixed ring plate 2 where the adjustment groove 4 is opened. Ratch teeth 202 are provided on the cavity wall of the cavity 201. The ratch teeth 202 are distributed on both sides of the cavity wall of the cavity 201, and the protruding directions of the ratch teeth 202 on both sides are opposite.

[0036] As Figure 4 shown, the tension adjustment assembly 6 includes a smooth shaft body 601. The end of the tension belt 7 is located on the shaft body 601. Ring platforms 602 are provided at both ends of the shaft body 601, and adjustment handles 603 are installed on the end sides of the ring platforms 602.

[0037] When the tension of the rotating component of the electric mechanism needs to be adjusted, hold the adjustment handle 603 with both hands and press it down or lift it. Since the tension belt 7 has a certain elasticity and has a certain margin of movement when pressing on the rotating component, it can rotate while keeping the rotating component fixed, thereby performing a dynamic balance test. Moreover, since the fixed mounting wheel 1 is hollow, it can be adapted to place rotating components of different sizes, and the tension of the tension belt 7 can be adjusted according to the size of the rotating component, or cooperate with the lifting seat platform.

[0038] As Figures 4-6 shown, a cavity 604 is provided inside the annular platform 602, an adjusting tooth 605 is provided in the cavity 604, the top of the adjusting tooth 605 abuts against and is stuck in the tooth recess of the ratchet tooth 202, a bottom plate 606 adapted to the cavity 604 is provided at the bottom of the adjusting tooth 605, a second spring 607 is provided in the cavity 604, one end of the second spring 607 is fixed to the bottom plate 606, and the other end is fixed to the cavity wall of the cavity 604.

[0039] More specifically, the ratchet teeth 202 provided on the cavity wall of the groove cavity 201 form a structure of an internal ratchet on the inner wall of the inner fixed ring plate 2. Under normal conditions, the adjusting tooth 605 is propped up by the second spring 607 and is always abutted against and stuck in the tooth recess position of the ratchet tooth 202. When the position of the tension belt 7 needs to be adjusted, hold the adjustment handle 603 and press it down. The adjusting tooth 605 on the annular platform 602 passes through and is limited and stuck on the ratchet tooth 202 in sequence until it is adjusted to the appropriate position, realizing the adaptive adjustment of the tension belt 7 of the detector according to power components of different sizes. Moreover, since the tension belt 7 has elasticity, it has a certain margin of rotation while being able to fix the rotating component.

[0040] As Figure 5 shown, a groove 8 is provided at the position of the fixed mounting wheel 1 corresponding to the ratchet tooth 202, and a third spring 9 is installed inside the groove 8.

[0041] More specifically, under normal conditions, the third spring 9 always presses against the outer wall of the annular platform 602. When the tension belt 7 reaches the tension limit and needs to be adjusted back, by retracting the tension adjustment assembly 6, the third spring 9 is deformed to leave a space for the adjusting tooth 605 to reset. At this time, the first spring 5 is located above the tension adjustment assembly 6 and can buffer the tension brought by the tension of the tension belt 7.

[0042] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
