Problems solved by technology

[0002] When assembling the front and rear end covers, stator and rotor of the generator assembly in the automotive motor industry, it is necessary to ensure the coaxiality of the front and rear end cover ear holes (such as figure 1 As shown), the method of first using the coaxiality correction rod of the auxiliary tooling is generally adopted, which has two disadvantages: 1) High manufacturing cost: a single product needs to make several pieces of correction rods for production turnover, the production of correction rods, High maintenance cost; 2) Low assembly efficiency: This method requires an additional process of inserting a coaxiality calibration rod, and the calibration rod is removed after the press-fitting is completed, resulting in waste of human resources and time loss

Embodiment Construction

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0023] Such as Figure 1~2 Shown is the composition structure of the generator 6 involved in this embodiment, which includes a front end cover 604 , a rotor part 603 , a stator part 602 and a rear end cover 601 . After assembly, it is necessary to ensure that the second ear hole 6041 on the front end cover 604 is coaxially arranged with the first ear hole 6011 on the rear end cover 601, that is, the coaxiality of the two ear holes (6041, 6011) needs to be guaranteed.

[0024] To solve the above problems, such as Figure 3-5 As shown, this embodiment provides a generator assembly fixture, including a bottom plate 1, an L-shaped bracket 3, a positioning sleeve 2, a lower positioning mandrel 4 and an upper positioning...

Abstract

The invention relates to a generator assembly fixture which comprises a bottom plate, an L-shaped support, a positioning sleeve, a lower positioning mandrel and an upper positioning mandrel,. The L-shaped support is arranged in an inverted mode, the positioning sleeve, a vertical arm of the L-shaped support and the lower positioning mandrel are fixedly installed on the bottom plate, and the upper positioning mandrel is fixedly installed on a transverse arm of the L-shaped support, and the lower positioning mandrel and the upper positioning mandrel are vertically and coaxially arranged. According to the assembly fixture, the high coaxiality of two hanging lug holes of a front end cover and a rear end cover can be guaranteed, the tool manufacturing and maintaining cost is saved through an integrated positioning mode, the operation working method is optimized, action waste is reduced, the production efficiency is improved, and valuable operation is eliminated.
