Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a clamp, particularly a clamp for a motor stator core. Background Technology

[0002] Motor stator core clamps are specialized tools used to fix and hold motor stator cores, and are widely used in processes such as moving and flipping stator cores.

[0003] Existing fixtures, such as the motor stator flipping fixture disclosed in the Chinese Patent Database (application number: 201820188018.2), include a hoisting mechanism, a horizontal guide rail, two sets of clamping mechanisms, and two vertical booms. The upper part of the horizontal guide rail is connected to the hoisting mechanism for moving or fixing it to an external fixed structure. Each set of clamping mechanisms includes an electromagnet device for attracting the stator to be fixed. The top ends of the two vertical booms are slidably connected to the horizontal guide rail via sliders, and the bottom ends are respectively connected to the two clamping mechanisms, so that the two vertical booms can move horizontally along the horizontal guide rail until the clamping mechanism clamps the stator to be fixed or until the clamping mechanism moves away from the stator to be fixed. The clamping mechanism and the booms are rotatably connected via rotating shafts. The axes of the rotating shafts in the two sets of clamping mechanisms coincide and are parallel to the horizontal guide rail, so that when the two clamping mechanisms clamp the stator to be fixed, they can drive the stator to be fixed to rotate.

[0004] In the aforementioned fixture, the electromagnet is supported by a rotating shaft, and the shaft and electromagnet are separate yet fixedly connected. When the stator core is heavy or the connection between the shaft and the electromagnet is unreliable, the electromagnet may separate from the shaft and drag the stator core down, posing a significant safety hazard. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a highly safe motor stator core clamp.

[0006] The objective of this utility model can be achieved through the following technical solution: A motor stator core clamp includes a bracket and two horizontally arranged electromagnets, each electromagnet including a housing. Support plates are provided on opposite sides of the two electromagnets, and the two housings are respectively fixed to the two support plates. The characteristic feature is that elongated support steps are formed on adjacent sidewalls of the two support plates, with the length of the support steps extending forward and backward. The support steps are composed of vertically arranged sidewalls and horizontally arranged bottom surfaces, with the sidewalls positioned above the bottom surfaces. Elongated support blocks are integrally formed on opposite sidewalls of the two housings, with the support blocks horizontally arranged and extending forward and backward, and the two support blocks respectively pressing against the bottom surfaces of the two steps. The bracket is also provided with a driving component for simultaneously driving the two support plates to move, and under the action of the driving component, the two electromagnets move closer or further apart.

[0007] The support block, integrally formed on the shell, presses against the bottom surface of the step to support the electromagnet upwards, thereby effectively preventing the electromagnet from falling. This not only ensures high safety but also provides a more stable clamping of the stator core, resulting in good operational stability.

[0008] In the aforementioned motor stator core clamp, the driving component includes a driving element and two connecting frames arranged side-by-side, with the connecting frames forming an L-shape. The driving element is positioned between the connecting frames and the support frame. The front end of the connecting frame is connected to the driving element, allowing the driving element to move the two connecting frames closer together or further apart. The rear end of the connecting frame is the aforementioned support plate. This design shortens the distance between components, making the entire clamp structure more compact and reducing space requirements.

[0009] In the aforementioned motor stator core clamp, reinforcing plates are horizontally pressed and fixed on the top surfaces of both connecting frames. The reinforcing plates are triangular in shape, with both ends extending to the corresponding ends of the connecting frames. The triangular reinforcing plates at the top of the connecting frames effectively strengthen them, thereby increasing the support strength for the electromagnets and further improving the clamp's operational stability and safety.

[0010] In the aforementioned motor stator core clamp, the driving components are two linear cylinders arranged side by side, with the cylinder bodies moving in opposite directions, and two connecting brackets fixed to the cylinder bodies of the two linear cylinders respectively. This design offers advantages such as simple structure and stable operation.

[0011] As another option, in the aforementioned motor stator core clamp, the front end of the connecting frame is slidably mounted on the bracket; the driving component includes a motor fixed on the bracket and a lead screw horizontally mounted on the bracket. The motor drives the lead screw to rotate, and the spiral directions at both ends of the lead screw are opposite. Both ends of the lead screw are equipped with matching nuts, and the front ends of the two connecting frames are respectively fixed with two nuts.

[0012] In the aforementioned motor stator core clamp, a connecting cylinder is vertically fixed above the bracket. An annular flange is formed on the outer wall of the upper end of the connecting cylinder, and the annular flange is coaxially arranged with the connecting cylinder to facilitate the connection between the bracket and the power equipment, thereby realizing the functions of clamp movement and flipping.

[0013] Compared with existing technologies, this motor stator core clamp has the following advantages:

[0014] 1. The support block, integrally formed on the shell, presses against the bottom surface of the step to support the electromagnet upward, thereby effectively preventing the electromagnet from falling. This not only ensures high safety but also allows for more stable clamping of the stator core, resulting in good working stability.

[0015] 2. A triangular reinforcing plate is installed on the top of the connecting frame, which can effectively strengthen the strength of the connecting frame, thereby improving the support strength for the electromagnet and further improving the stability and safety of the fixture operation.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, the stator core clamp of this motor includes a bracket 1 and two horizontally arranged electromagnets 2. In the actual product, the electromagnets 2 are elongated and extend from front to back. The basic structure and principle of these electromagnets 2 are existing technologies and will not be described in detail here.

[0023] Specifically

[0024] like Figure 1 and Figure 2As shown, the electromagnet 2 includes a housing 2a. Support plates 3 are provided on opposite sides of the two electromagnets 2, meaning the two electromagnets 2 are positioned between the two support plates 3. The two housings 2a are respectively fixed to the two support plates 3, and in the actual product, the housings 2a are fixed to the corresponding support plates 3 by horizontally arranged bolts. Elongated support steps 3a are formed on adjacent sidewalls of the two support plates 3, extending front to back. Each support step 3a consists of a vertically arranged side surface 3a1 and a horizontally arranged bottom surface 3a2, with the side surface 3a1 positioned above the bottom surface 3a2. Elongated support blocks 2b are integrally formed on opposite sidewalls of the two housings 2a. These support blocks 2b are horizontally arranged and extend front to back, and are positioned within the two support steps 3a and press against the bottom surfaces 3a2. The bracket 1 is also equipped with a driving component for simultaneously moving the two support plates 3, causing the two electromagnets 2 to move closer or further apart.

[0025] The support block 2b, integrally formed on the housing 2a, presses against the bottom surface 3a2 of the step to support the electromagnet 2 upward, thereby effectively preventing the electromagnet 2 from falling. This not only ensures high safety but also allows for more stable clamping of the stator core, resulting in good working stability.

[0026] In this embodiment,

[0027] The driving component includes a driving element and two connecting frames 4 arranged side by side, with the connecting frames 4 being L-shaped. The driving element is located between the connecting frames 4 and the support 1. The front end of the connecting frame 4 is connected to the driving element so that the driving element can drive the two connecting frames 4 to move closer or further apart. The rear end of the connecting frame 4 is the aforementioned support plate 3. By adopting the above design, the distance between the components can be shortened, making the entire fixture structure more compact and reducing space occupation.

[0028] To further explain, such as Figure 1 and Figure 3 As shown, reinforcing plates 5 are horizontally pressed and fixed on the top surfaces of both connecting frames 4. The reinforcing plates 5 are triangular, and their two ends extend to the corresponding ends of the connecting frames 4. The triangular reinforcing plates 5 on the top of the connecting frames 4 can effectively strengthen the strength of the connecting frames 4, thereby improving the support strength for the electromagnet 2 and further improving the stability and safety of the fixture operation.

[0029] The specific structure of the drive unit is as follows: the drive unit consists of two linear cylinders 6 arranged side by side, with the cylinder bodies of the two linear cylinders 6 moving in opposite directions, and two connecting brackets 4 respectively fixed on the cylinder bodies of the two linear cylinders 6. This design has advantages such as simple structure and stable operation.

[0030] In the actual product, a connecting cylinder 7 is vertically fixed above the bracket 1. An annular flange 7a is formed on the outer wall of the upper end of the connecting cylinder 7, and the annular flange 7a is coaxially arranged with the connecting cylinder 7 to facilitate the connection between the bracket 1 and the power equipment, so as to realize the functions of clamp movement and flipping.

[0031] Example 2

[0032] The structure and principle of this embodiment are basically the same as those of embodiment one. The difference is that the front end of the connecting frame 4 is slidably mounted on the bracket 1; the driving component includes a motor fixed on the bracket 1 and a lead screw horizontally mounted on the bracket 1. The motor drives the lead screw to rotate. The spiral directions at both ends of the lead screw are opposite. Both ends of the lead screw are equipped with matching nuts, and the front ends of the two connecting frames 4 are respectively fixed with two nuts.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
