Description

[Detailed Description of the Invention] Industrial Application Field The present invention mainly relates to a mounting device for a skeleton type electric motor.

BACKGROUND TECHNOLOGY Conventionally, this type of motor mounting device has been
The configuration was as shown in the figure. In the figure, 1 is an electric motor, and screws 3 and nuts 4 are attached to the motor mounting plate 2.
In addition, the electric motor mounting plate 2 was attached to the resin frame 5 with screws 6.

Problems that the invention aims to solve With this conventional configuration, there is a problem in that not only many parts are required to attach the electric motor to the frame, but also a large number of man-hours are required to assemble it. Ta.

This invention solves these problems,
Simplify the motor mounting device, reduce the number of parts,
The aim is to significantly reduce the number of assembly steps.

Means for Solving the Problem In order to solve this problem, the present invention has a resin box-like frame that is open on one side and houses a skeleton electric motor inside, and a frame that is provided in the opening so that it can be opened and closed. and a lid, and the inside of the frame has a lower opening side;
A first support part is provided that is integrally formed with a raised inner side and supports one end in the axial direction of the stator core of the electric motor and an outer peripheral part of the stator core, and the lid has a first support part that closes the opening. The stator core is constructed of a second support portion that comes into contact with the other end of the stator core when the stator core is rotated.

Function With this configuration, the motor can be easily attached to the frame by inserting it through an opening wider than the inside of the frame, and fixing it to one end of the stator core in the axial direction using the first support formed inside the frame. After supporting the outer periphery of the child core, the lid is closed and the other end of the stator core is supported by the second support part, thereby easily completing the process.

Embodiment An embodiment of the present invention will be described below based on FIG. In the figure, reference numeral 101 denotes an electric motor, which is housed in a box-shaped frame 102 made of resin through an opening 102a, and has a plurality of motors integrally formed inside the frame 102 with the opening 102a side lower and the inner side higher. One end of the stator core 101a in the axial direction and the outer peripheral portion of the stator core 101a are supported by the rib 103. At the end of the opening 102a of the frame 102, two lids 104, 104 are integrally attached to a hinge portion 105.
It is provided so that it can be opened and closed freely. 2 lids 1
04 is formed so that when the opening 102a is closed, the tips overlap and are fixed with a screw 107, as shown by the two-dot chain line in the figure. The lid 104 is provided with a presser rib 106 that presses and supports the other end of the stator core 101a when the opening 102a is closed. Note that the frame body 102 is provided in a device main body (not shown).

In the above configuration, the electric motor 10 to the frame body 102
1 is installed using an opening 1 wider than the inside of the frame 102.
The electric motor 101 is inserted from 02a, and the rib 103 supports one end of the stator core 101a in the axial direction and the outer circumference of the stator core 101a. Then, the tips of the two lids 104 are overlapped to close the opening 102a and fixed with screws 107. At this time, the holding rib 106 provided on the lid 104 presses and supports the other end of the stator core 101a, and the installation of the electric motor 101 is completed.

As described above, according to the motor mounting device of the embodiment of the present invention, the motor 101 can be mounted on the frame 102.
A lid 1 that houses an electric motor 101 and can be opened and closed freely.
04, the rib 103 of the frame body 102
The electric motor 101 is supported and fixed from the vertical and horizontal directions by the ribs 106 of the lid 104, and the work is completed. The mounting position of the motor 101 can be accurately regulated and firmly fixed, and the positioning accuracy and fixing strength of the electric motor 101 can be improved. Further, the outermost part of the motor 101, which is the outer periphery of the stator core 101a, is abutted and supported by the ribs 103 of the frame 102.
Since the opening 102a side is formed low, the opening 102a of the frame body 102 is wider than the inside, and the electric motor 101 can be easily inserted, and the number of parts can be reduced. Further, the strength of the frame 102 is increased by the ribs 103 despite the reduction in the number of parts, and moreover, the strength of the frame 102 is increased by the ribs 103 near the opening 102a.
Although the effect of 03 is slightly reduced because the ribs are low, since it is closed by the strong lid 104 provided with the ribs 106, the strength of that part can also be improved.

In the embodiment, two lids are provided and the lids are stacked and fixed, but even if one lid is used to open and close and its tip is fixed to the frame, there will be no difference in its operation and effect.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the electric motor can be installed by simply storing the electric motor in the frame and closing the lid provided so that it can be opened and closed. The support part and the second support part of the lid support and fix the electric motor from the vertical and horizontal directions, completing the work, improving the positioning accuracy and fixing strength of the electric motor, and improving the positioning accuracy and fixing strength of the electric motor. Since it is also possible to prevent vibrations generated from the blades etc. attached to the device, the accuracy of the device body can be improved. In addition, since the first support part is provided on the frame so that the opening of the frame is wide, the electric motor can be easily inserted, the number of parts is reduced, and manufacturing costs are significantly reduced. can get.
