The utility model discloses with upper and lower bearing housing on same guide pillar, make it have good concentricity, prevent that motor element from rotating the in-process and producing the tremble and damaging motor element, simultaneously, the utility model discloses only need a pressure equipment can accomplish the assembly process, compare in positive and negative twice pressure equipment in the past, this frock has improved work efficiency greatly.

Description

Double-bearing assembly tool for motor

Technical Field

The utility model relates to a motor assembly field especially relates to a duplex bearing assembly fixture for motor.

Background

The motor is an electromagnetic device for realizing electric energy conversion or transmission according to an electromagnetic induction law. The motor mainly functions in generating driving torque, and the electric energy is converted into magnetic energy to generate rotation action so as to drive other mechanical motion, so that the bearing is indispensable in the motor.

When the motor part is overlarge along the axial direction, two bearings are often required to be installed to stabilize the motor part, otherwise the part is often vibrated when rotating at a high speed to damage the motor part. When traditional duplex bearing installation, install the bearing of part one side earlier, install the opposite side again after the installation is accomplished, often can lead to two bearings concentricity lower like this, thereby also can cause the tremor of part to damage the part.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem that exists, the utility model provides a when guaranteeing the installation of duplex bearing, two bearings keep the frock of better concentricity from top to bottom.

In order to solve the technical problem, the utility model discloses a technical scheme as follows: the double-bearing assembly tool for the motor comprises a base, a bearing guide pillar and a pressure head, wherein the base comprises a bearing surface, the top end of the bearing surface is used for supporting a main body of a part to be assembled, a guide boss protruding out of the bearing surface and guiding the part to be assembled is arranged on the inner side of the geometric center of the bearing surface, and the bearing guide pillar is arranged on the geometric center of the guide boss; the pressure head is of a hollow structure with an opening at the lower end, and the inner diameter of the pressure head is matched with the outer diameter of the bearing guide pillar.

In the double-bearing assembly tool for the motor, the upper bearing and the lower bearing are positioned on the same axis through the bearing guide post, so that the double-bearing assembly tool has better concentricity.

Furthermore, a bearing support leg coaxial with the bearing guide post is further arranged on the guide boss. The bearing support leg is used for preventing the bearing contacted with the base from crushing the base in the press-fitting process.

Therefore, the utility model discloses a duplex bearing assembly fixture for motor has following beneficial effect than traditional technical means:

1. the utility model discloses with upper and lower bearing housing on same guide pillar, make it have good concentricity, prevent that motor element from rotating the in-process and producing the tremble and damaging motor element.

2. The utility model discloses only need a pressure equipment can accomplish the assembly process, compare in two times pressure equipments of positive and negative in the past, this frock has improved work efficiency greatly.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

The bearing assembly comprises a base 1, a bearing guide post 2, a pressure head 3, a bearing surface 4, a guide boss 5, a bearing support leg 6, a part to be assembled 7, a first bearing 81 and a second bearing 82.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to assist in understanding the embodiments of the invention defined by the claims. It includes various specific details to assist understanding, but they are to be construed as merely illustrative. Accordingly, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Also, in order to make the description clearer and simpler, a detailed description of functions and configurations well known in the art will be omitted.

The invention will be further described with reference to the following several drawings of the specification: referring to fig. 1, the dual-bearing assembly fixture for the motor comprises a base 1, a bearing guide post 2 and a pressure head 3, wherein the base 1 comprises a bearing surface 4, the top end of the bearing surface 4 is used for supporting a main body of a part 7 to be assembled, a guide boss 5 protruding from the bearing surface 4 and guiding the part 7 to be assembled is arranged on the inner side of a geometric center of the bearing surface 4, the bearing guide post 2 is arranged on the geometric center of the guide boss 5, and the base 1 and the bearing guide post 2 are integrally formed. And a bearing support leg 6 which is coaxial with the bearing guide post 2 is also arranged on the guide boss 5. The pressure head 3 is of a hollow structure with an opening at the lower end, and the inner diameter of the pressure head 3 is matched with the outer diameter of the bearing guide pillar 2.

The utility model discloses the theory of operation briefly states: the utility model discloses in, operating personnel at first arrange base 1 in under the pressure head 3, make pressure head 3 can wrap up completely and live bearing guide pillar 2. Subsequently, the press head 3 is lifted, the first bearing 81 is placed on the bearing support leg 6 along the bearing guide post 2, the part 7 to be assembled is placed on the supporting surface 4 along the guide boss 5, after the part is placed stably, the second bearing 82 (namely, the upper bearing) is placed along the bearing guide post 2 again to be contacted with the part 7 to be assembled, after the part is placed stably, the press machine drive head 3 is slowly pressed downwards, the first bearing 81 and the second bearing 82 are pressed into the part 7 to be assembled, and then the assembled part is taken out.
