Description

Technical Field

[0001] The utility model relates to the technical field of motor bases, in particular to a large DC motor base. Background Art

[0002] The outer shell of the motor stator is called the frame. As a DC motor, the frame has two main functions: one is to fix the main poles, commutator poles and end covers, and to support and fix the entire motor; the other is that the frame itself is also part of the magnetic circuit, thereby forming a magnetic path between the poles. The part through which the magnetic flux passes is usually made of stacked frame punchings. In order to ensure that the frame has sufficient mechanical strength and good magnetic conductivity, the frames of large and medium-sized DC motors are generally made of welded steel plates.

[0003] The processing requirements of various components of existing large DC motors are different. Therefore, the various components of large DC motors are processed in different workshops or different factory areas and then assembled in one workshop. Due to its heavy weight, the transfer of large DC motor bases is mostly assisted by lifting equipment or forklifts. Since there is no slot for the forklift fork arm to insert on the existing large motor base, when the base is transferred by a forklift, the forklift fork arm is directly inserted into the inside of the base. Although a protective pad is placed at the contact between the forklift fork arm and the base, during actual operation, if the base is offset when encountering bumps, the forklift fork arm is very likely to contact and collide with the inside of the base, which will cause the entire base to be scrapped. Based on this, a large DC motor base is provided. Utility Model Content

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.

[0019] See also Figures 1 to 3 In the embodiment of the utility model, a large DC motor base includes a motor base 1 composed of a base body 101, an inner support plate 102, and a front shaft support plate 103. A plurality of inner support plates 102 are provided, and the plurality of inner support plates 102 are evenly distributed on the inner side of the base body 101 and fixed by welding. The front shaft support plate 103 is fixed to the front end of the base body 101 by bolts. A transfer assembly 2 is distributed on the base body 101 and the front shaft support plate 103. The transfer assembly 2 is used for inserting the fork arm of a forklift to realize a convenient transfer operation.

[0020] The transfer assembly 2 includes a first plug-in unit and a second plug-in unit. The first plug-in unit is used to provide an insertion space for a forklift to transfer the machine base body 101; the second plug-in unit is used to provide an insertion space for a forklift to transfer the front shaft support plate 103, and at the same time provide a guide for the docking of the front shaft support plate 103 with the machine base body 101.

[0021] The first plug-in unit includes a first square through-groove 201, a recessed groove 202, and an L-shaped partition 203; the first square through-groove 201 is arranged at the four end corners of the base body 101 and penetrates to the inner side of the base body 101, the recessed groove 202 is arranged at the four end corners of the inner support plate 102 and penetrates both sides of the inner support plate 102, the recessed groove 202 is aligned with the first square through-groove 201 in the horizontal direction, and the channel formed by the first square through-groove 201 and the recessed groove 202 is used for the forklift fork arm to be inserted, so as to realize the convenient transfer of the base body 101; the L-shaped partition 203 is fixed between two adjacent inner support plates 102 and between the inner support plate 102 and the inner wall of the base body 101, and the L-shaped partition 203 blocks the channel formed by the first square through-groove 201 and the recessed groove 202, so as to separate the channel from the inner cavity of the base body 101.

[0022] In this embodiment: when the machine base body 101 needs to be transferred, it is only necessary to insert the fork arm of the forklift into the two lower first square through grooves 201 or the two upper first square through grooves 201. At this time, the fork arm of the forklift does not contact the inner cavity of the machine base body 101, which effectively ensures that the inner cavity of the machine base body 101 will not be damaged during the transfer process, thereby improving the transfer safety of the machine base body 101.

[0023] Please refer to Figures 1 to 3 The second plug-in unit includes a second square through-groove 205 and a docking column 206; the front shaft support plate 103 is a rectangular structure as a whole and a center hole for the rotor shaft to pass through is opened in the middle. The second square through-groove 205 is opened at the four end corners of the front shaft support plate 103 and passes through both sides of the front shaft support plate 103; the docking column 206 is fixed to the side of the front shaft support plate 103 close to the base body 101 and is located on the outside of the second square through-groove 205. The inner cavity of the docking column 206 is aligned with the second square through-groove 205. The channel formed by the second square through-groove 205 and the docking column 206 is used for the forklift fork arm to be inserted, so as to realize the convenient transfer of the front shaft support plate 103.

[0024] The outer wall size of the docking column 206 matches the inner wall size of the first square through-groove 201, and the automatic alignment operation of the front shaft support plate 103 and the base body 101 is realized by inserting the docking column 206 into the inner side of the first square through-groove 201; the end of the docking column 206 close to the base body 101 is a contracted arc structure, and the length of the docking column 206 is greater than the length of the rotor shaft protruding from the outside of the base body 101.

[0025] In this embodiment: after the rotor is installed inside the base body 101, the front bearing support plate 103 needs to be docked with the base body 101. At this time, the forklift fork arm can be inserted into the two lower second square through grooves 205 or the two upper second square through grooves 205, so that the forklift can easily transfer the front bearing support plate 103 close to the base body 101.

[0026] During this process, when the front bearing support plate 103 has not yet contacted the rotor shaft, the docking column 206 will first be inserted into the first square through-slot 201, so that the front bearing support plate 103 and the central axis of the base body 101 are aligned, that is, the center hole in the middle of the front bearing support plate 103 is automatically aligned with the rotor shaft. Afterwards, when the front bearing support plate 103 continues to approach the base body 101, the front bearing support plate 103 can be easily connected with the rotor shaft, which can effectively improve the assembly efficiency of the DC motor.
