Embodiment 1

[0036] This embodiment proposes a fixing device for the motor stator and the frame according to the above-mentioned fixing method of the motor stator and the frame, as shown in the attached Figure 2-8 As shown, the partition can be the front partition 1 of the machine base or the rear partition 4 of the machine base, and the pressure ring can be the front pressure ring 5 of the stator or the rear pressure ring 3 of the stator. On the bottom plate, an annular groove is processed on the side of the iron core, and at the same time, 2 to 14 fixing ribs 7 are evenly arranged in the circumferential direction of the annular groove, and grooves are opened on the annular groove of the separator. Welded on the groove; the annular groove corresponding to the annular groove of the partition plate is provided with the annular groove of the pressure ring, and a trapezoidal groove 8 is provided on the annular groove of the pressure ring corresponding to the position of the fixing rib, and th...

Embodiment 2

[0038] This embodiment proposes another fixing device for the motor stator and the machine base according to the above-mentioned fixing method of the motor stator and the machine base. The connection is fixed, as attached Figure 9 As shown, the difference from Example 1 is that the fixing of the diaphragm and the pressure ring is the superposition of the diaphragm and the pressure ring, and screw holes are evenly opened on the ring part superimposed on the diaphragm and the pressure ring, and the diaphragm is directly connected by bolts. Connect and fix with the pressure ring.

Abstract

The invention discloses a mode and device for fixing a stator and a base of a motor. The base is internally provided with a base front clapboard and a base rear clapboard, the stator is provided with a stator front clamping ring and a stator rear clamping ring, the base front clapboard and the stator front clamping ring are fixed, the base rear clapboard and the stator rear clamping ring are fixed. The fixing mode is characterized in that the base front clapboard and the stator front clamping ring are fixedly connected by virtue of bolts, and the base rear clapboard and the stator rear clamping ring are fixed by virtue of the bolts or are connected in an interference fit manner. According to the invention, the hidden dangers that the traditional fixing of the stator and the base of the motor is not firm and the stator of the motor is damaged are solved, and a mode and device for fixing the base and stator of the motor, which can eliminate the hidden dangers, provide reliable fastening for the stator, reduce process operational difficulty, be beneficial to mass production of the motor and can avoid secondary damage to the stator when the stator operates, are provided.

Description

technical field [0001] The invention relates to a fixing method and a fixing device of a motor component, in particular to a fixing method and a fixing device of a motor stator and a frame. Background technique [0002] At present, for the fixing of the stator and the frame of the motor, especially the fixing of the stator and the frame of the box-type structure, after the stator is inserted into the frame, welding is used on the top of the contact between the frame and the stator pressure ring. way into the fixing of the stator, as attached figure 1 As shown, when this method is used for fixing, it can only be welded in the upper part of the machine base as large as possible, which may result in unreliable welding due to the limited operating space during the welding operation, and secondly, in the welding operation. When welding, if the stator is not well protected, it is very likely that the welding slag will enter the stator during welding and form welding slag on the i...
