DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.
[0023] Embodiment 1: A front cover of a motor bearing fixing fixture, see Figure 1 , Figure 2 and Figure 4As shown, it includes a front cover body 1 and an arc portion 101. Two arc portions 101 for clamping motor bearings are arranged on the front cover body 1. The front cover body 1 is subjected to natural color anodizing treatment, and the thickness of the oxide layer is not less than 10um to increase the service life of the front cover body 1. The surface of the front cover body 1 is sprayed with outdoor powder color according to HC-0966, and the film thickness is 80-200um. Four mounting holes 2 for connecting the clamp are opened on the front cover body 1, and it also includes a first noise reduction mesh 9 and a second noise reduction mesh 10. Multiple noise reduction holes 8 are opened on both sides of the front cover body 1. The first noise reduction mesh 9 is set on both sides of the outside of the front cover body 1 by gluing, and the second noise reduction mesh 10 is set on both sides of the inside of the front cover body 1 by gluing. The first noise reduction mesh 9 and the second noise reduction mesh 10 are respectively located on both sides of the noise reduction hole 8.
[0024] When the motor bearing and the shaft need to be assembled, the front cover body 1 is assembled with the clamp by inserting bolts into the mounting holes 2, and the bearing is clamped and fixed by the arc portion 101. When the shaft is knocked into the motor bearing, the noise generated by the knocking vibration is first reduced by the second noise reduction mesh 10 on the front cover body 1, and then further reduced by the silencer principle through the noise reduction hole 8. Finally, the noise generated by the vibration is softened by the first noise reduction mesh 9 to reduce the sound emitted, thereby enabling the clamp to have its own noise reduction function.
[0025] Example 2: Based on Example 1, refer to Figure 2 and Figure 3 As shown, it also includes six ejector pin positions 3 fixedly connected to the front cover body 1 by injection molding, and the depth of the indentation of the ejector pin position 3 does not exceed 0.2mm; it also includes a threaded hole 4 opened on one side of the front cover body 1, and a chamfered portion 401 is provided at the threaded hole 4 to facilitate the alignment of the screw into the threaded hole 4, and a large hole 5 is opened on the other side of the front cover body 1; it also includes a first protective strip 6 installed on both sides of the front cover body 1 by gluing, and a second protective strip 7 is installed in the middle of the front cover body 1 by gluing, and the first protective strip 6 and the second protective strip 7 are both made of soft rubber to elastically buffer the impact force.
[0026] When the clamp needs to be pried open, the front cover body 1 can be separated from the clamp by prying open the ejector pin position 3. When the front cover body 1 falls, the first protective strip 6 and the second protective strip 7 can protect the front cover body 1 and cushion the impact force to prevent the front cover body 1 from being broken or damaged. When the screw needs to be screwed into the threaded hole 4, the chamfered portion 401 can guide the screw so that the screw can be aligned and slide into the threaded hole 4.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
