Abstract
Description
Technical Field
[0001] The utility model relates to a hoisting tool for a permanent magnet synchronous motor shell, which is prepared by adopting a wire cutting and welding method and can be firmly clamped with the motor shell. Background Art
[0002] The permanent magnet synchronous motor housing is primarily made by casting, featuring a large inner diameter and a continuous interior. The outer wall is designed with heat sinks, an electrical control box, and other features. Drilling holes in the housing typically requires hoisting the housing to the processing location. Because the housing is very heavy, it is typically hoisted to the desired location using a lifting sling. Current hoists are simple J-shaped hooks, which are very unstable and can easily cause the housing to fall from the sling, causing scratches or injuring the operator. Therefore, optimization of the hoist is currently needed to ensure stable hoisting of the housing. Utility Model Content
[0003] The utility model aims to provide a motor housing hoisting fixture, and solves the technical problem of optimizing the structure of the hoisting fixture so as to make the hoisting of the motor housing more stable.
[0004] The motor housing lifting fixture is an integrated structure, which includes a suspension arm, a connecting arm, a first hanging arm, and a second hanging arm; the suspension arm is a circular pancake-shaped structure as a whole, and its interior is hollow with a lifting hole; the connecting arm is an arc-shaped structure, one end of which is an integrated structure with the suspension arm, and the other end opposite to it is an integrated structure with the first hanging arm and the second hanging arm; the first hanging arm and the second hanging arm are both hook-shaped and arranged facing each other, wherein the first hanging arm is arranged horizontally and keeps the hook-shaped end position downward and facing the second hanging arm, and the second hanging arm is arranged obliquely and faces the first hanging arm arm; one side of the first hanging arm is a straight rod structure; one side of the second hanging arm is an arc-shaped structure and keeps corresponding to the arc of the connecting arm; the first hanging arm is in the middle position where the connecting arm and the second hanging arm are connected as a whole; the end of the first hanging arm has a first protrusion extending along both sides of the first hanging arm, and the first protrusion hangs on the outer bottom of the electric control box of the motor housing, and the end of the second hanging arm has a second protrusion extending along both sides of the second hanging arm, and the second protrusion hangs on the inner cavity of the electric control box of the motor housing.
[0005] The beneficial effects of the present invention are as follows: by extending another hanging arm structure on the existing lifting fixture, the motor housing is suspended in both the inside and outside directions from two directions, thereby ensuring that the motor housing no longer swings during the lifting process, making the entire lifting process more stable; by designing the extended first protrusion and the second protrusion, the contact area between the end of the hanging arm and the electric control box of the motor housing is extended, further ensuring the stability of the lifting.

[0012] Please refer to Figure 1 The motor housing lifting fixture in the figure is an integrated structure, which can be made by wire-cutting electric discharge. In order to avoid the swing of the motor housing, the fixture in this case is designed with a hanging arm structure in each of the two relative directions that can swing during lifting, so that the housing can be firmly hung.
[0013] The fixture design features a suspension arm 1 at the location where the lifting hook is engaged. The suspension arm 1 is generally circular in shape, with a hollow hanging hole 11 punched inside. This facilitates the hanging of the fixture while ensuring sufficient strength. In practical applications, the suspension arm 1 can be stamped to enhance its overall strength.
[0014] In the figure, the connecting arm 2 structure is located below the suspension arm 1, which makes it easy to connect the suspension arm 1, the first suspension arm 3, and the second suspension arm 4 into one. The connecting arm 2 is an arc-shaped structure and its thickness is consistent with that of the suspension arm 1, which ensures that the center of gravity of the entire clamp is in a suitable position while simplifying the structure of the entire clamp.
[0015] Below the connecting arm 2 in the figure are the first and second hanging arms 3 and 4, respectively. Both arms are hook-shaped and face each other. The connection between the first arm 3 and the connecting arm 2 is a rod-shaped structure that extends along the arc formed by the connecting and second arms 4. At the end of the first arm 3, a first protrusion 31 is designed. This first protrusion 31 extends along both sides of the arm 3, ensuring stable hooking to the outer bottom of the motor housing's electrical control box. The second arm 4 is also curved and maintains the same shape as the connecting arm 2. The connecting and second arms 4 are curved in the same direction. At the end of the second arm 4, a second protrusion 41 extends along both sides of the arm 4, ensuring sufficient strength and contact area with the inner cavity of the motor housing's electrical control box. As shown in the figure, the first and second protrusions 31 and 41 are arranged opposite each other, with a gap just wide enough to accommodate the motor housing.
