Description

Technical Field

[0001] The utility model relates to the field of fixtures and tooling, and particularly relates to a new type of electric drum assembly tooling. Background Art

[0002] At present, in the market, when assembling an electric drum, the traditional manual assembly method is used to connect the stator assembly and the rotor assembly. Using the traditional manual assembly method, it is not easy to install. During the production process, workers install the rotor assembly into the stator assembly. Due to the influence of the magnetic field of the magnetic steel, the rotor assembly will tilt, resulting in the fracture of the magnetic steel, increasing the production cost, reducing the production efficiency, and being prone to pinching hands. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a new type of electric drum assembly tooling.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A new type of electric drum assembly tooling includes a lower fixing plate and a support column. A support column is fixedly installed at the center of the upper end surface of the lower fixing plate. A vertical cylindrical clamping hole is fixedly opened at the center of the upper end surface of the support column. The outer ring surface of the support column and the clamping hole are on the same central axis, and the outer ring surface of the support column is stepped from top to bottom.

[0006] Furthermore, the support column is composed of multiple telescopic columns. The multiple telescopic columns of the support column are sleeved with telescopic columns with gradually increasing diameters from the center of the support column to the outside, and the multiple telescopic columns form a stepped shape.

[0007] Furthermore, each section of the telescopic column is a frustum of a cone with the maximum outer diameter at the upper end smaller than the maximum outer diameter at the lower end.

[0008] Furthermore, the telescopic column includes a fixed telescopic column at the center and a movable telescopic column slidably sleeved on the outer ring surface of the fixed telescopic column. One end of the fixed telescopic column is fixedly installed on the lower fixing plate.

[0009] Furthermore, there are multiple movable telescopic columns, and the multiple movable telescopic columns have the same structure. A central connection through hole is opened in the length direction on the upper end surface of the movable telescopic column, and the diameters of the multiple movable telescopic columns increase step by step.

[0010] Furthermore, the lower end surfaces of the multiple movable telescopic columns are all connected with return springs, and the other ends of the return springs are fixedly installed on the lower fixing plate. The return springs are sleeved on the outer ring surface of the fixed telescopic column.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model can match stator and rotor components of different models. By changing the length of the support column and using the diameters of the outer ring surfaces of the support columns with different lengths to match the models of rotors with different inner diameters, the effect of one tooling fixture matching multiple product models is achieved, and the production cost is reduced.

[0017] The following elaborates on the preferred embodiments of the utility model in conjunction with the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the utility model more clearly defined.

[0018] Embodiment 1

[0019] See Figure 1-2 As shown, a new type of electric drum assembly tooling fixture includes a lower fixing plate and a support column. A support column is fixedly installed at the center of the upper end surface of the lower fixing plate. A vertical cylindrical clamping hole is fixedly opened at the center of the upper end surface of the support column. The outer ring surface of the support column and the clamping hole are on the same central axis, and the outer ring surface of the support column is stepped from top to bottom.

[0020] The stator is supported through the cylindrical clamping hole opened on the support column, and the positioning of the rotor housing is realized through the outer ring surface of the support column. Through the coaxial clamping hole and the outer ring surface of the support column, the coaxial positioning of the stator and the rotor is conveniently realized. At the same time, the stepped support column can match rotor housings of different sizes through stepped parts with different diameters, achieving the effect of one tooling fixture matching multiple motors and reducing the use cost.

[0021] Embodiment 2

[0022] The general structure of this embodiment is the same as that of Embodiment 1. The difference is that: the support column is composed of multiple telescopic columns. The multiple telescopic columns of the support column are sleeved with telescopic columns with diameters increasing from small to large in sequence from the center of the support column to the outside, and the multiple telescopic columns form a stepped shape.

[0023] On the premise of achieving better matching of motors of different models through the telescopic structure, the height of the tooling fixture is shortened.

[0024] Each section of the telescopic column is frustum-shaped with the maximum outer diameter at the upper end smaller than that at the lower end.

[0025] The telescopic column includes a fixed telescopic column at the center and a movable telescopic column slidably sleeved on the outer ring surface of the fixed telescopic column. One end of the fixed telescopic column is fixedly installed on the lower fixing plate.

[0026] There are multiple movable telescopic columns, and the structures of the multiple movable telescopic columns are the same. A central connection through hole is provided on the upper end surface of the movable telescopic column in the length direction, and the diameters of the multiple movable telescopic columns increase step by step.

[0027] Embodiment 3

[0028] The main structure of this embodiment is the same as that of Embodiment 2, except that: a return spring is connected to the lower end surface of each of the multiple movable telescopic columns, and the other end of the return spring is fixedly installed on the lower fixing plate, and the return spring is sleeved on the outer ring surface of the fixed telescopic column.

[0029] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed by the present invention should be included in the protection scope recorded in the claims.
