[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0035] In the drawings, the same reference numerals all refer to the same components. Example

[0036] like Figure 1-3As shown, the utility model provides an electric spindle, including an electric spindle body 8 and an electric spindle housing 1, and the electric spindle housing 1 includes:

[0037] The housing jack 2 is arranged on the top surface of the electric spindle housing 1;

[0038] The dustproof component 3 is arranged on the top surface of the electric spindle housing 1 and includes:

[0039] The fixing base 4 has two sets of pin holes 401 and a card slot 402. The fixing base 4 is arranged on the top surface of the electric spindle housing 1. The two sets of pin holes 401 are symmetrically arranged on one side surface of the fixing base 4, and the card slot 402 is arranged inside the fixing base 4.

[0040] Latch 5, which is disposed inside the pin hole 401;

[0041] Sealing layer 7, the sealing layer 7 is adhesively connected to the card slot 402;

[0042] The plug 5 is inserted into 401 and the housing socket 2 , and the sealing layer 7 is in contact with the electric spindle body 8 and the electric spindle housing 1 .

[0043] Specifically, such as Figure 1-3 As shown, the housing socket 2 and the pin hole 401 are used to install the pin 5, the pin 5 is used to thread the fixing seat 4 to the electric spindle housing 1, the fixing seat 4 is used to set the slot 402 and set the sealing layer 7 inside the slot 402, the sealing layer 7 is used to isolate dust and prevent dust from entering the interior from the joint between the electric spindle body 8 and the electric spindle housing 1.

[0044] The pin hole 401 and the housing socket 2 are circular and both have built-in threads.

[0045] Specifically, such as Figure 1-3 As shown, the circular arrangement enables the pin hole 401 and the housing socket 2 to evenly distribute stress when subjected to force, thereby avoiding damage caused by stress concentration. At the same time, the circular arrangement also facilitates processing and installation, thereby improving work efficiency.

[0046] The latch pin 5 is a hexagon socket bolt, and the latch pin 5 and the pin hole 401 have the same size as the housing socket 2. The latch pin 5 and the pin hole 401 have the same size as the housing socket 2.

[0047] Specifically, such as Figure 1-3 As shown, since the pin 5, pin hole 401 and housing receptacle 2 have the same dimensions, this ensures that the pin 5 can be accurately inserted into the pin hole 401 and housing receptacle 2, forming a tight fit. This helps to reduce loosening or falling off caused by excessive clearance, thereby enhancing the stability and reliability of the connection.

[0048] The fixing seat 4 is threadedly connected to one side of the housing socket 2 of the electric spindle housing 1 through the latch 5 and the pin hole 401 .

[0049] Specifically, such as Figure 1-3 As shown, the threaded connection has self-locking properties, which can maintain the stability of the connection when subjected to external forces and is not easy to loosen or fall off. This tightness ensures a stable connection between the fixing base 4 and the electric spindle housing 1.

[0050] The sealing layer 7 is a rubber pad. The size of the sealing layer 7 is smaller than that of the fixing seat 4. The sealing layer 7 has the same size as the card slot 402. The fixing seat 4 and the sealing layer 7 are both annularly arranged. The inner walls of the fixing seat 4 and the sealing layer 7 are attached to the outer side of the electric spindle body 8.

[0051] Specifically, such as Figure 1-3 As shown, the rubber pad, serving as sealing layer 7, exhibits excellent elasticity and plasticity, allowing it to adhere tightly to the exterior of the motorized spindle body 8, forming an effective sealing barrier. This close fit helps prevent the penetration of liquids, gases, or solid particles, ensuring a clean and stable environment within the motorized spindle body 8.

[0052] The electric spindle housing 1 includes:

[0053] A sound insulation shell 9 is provided on the inner wall surface of the electric spindle housing 1;

[0054] The sound-absorbing cotton 6 is arranged on the inner wall of the sound-insulating shell 9 , and the sound-absorbing cotton 6 is in contact with the electric spindle body 8 .

[0055] Specifically, such as Figure 1-3 As shown, the soundproof shell 9 acts as the first layer of sound insulation, effectively isolating the noise generated by the motorized spindle body 8 from propagating outward. The sound-absorbing cotton 6 has excellent sound absorption properties, further absorbing and transforming the noise that penetrates the shell 9. The microporous structure within the sound-absorbing cotton 6 effectively absorbs sound wave energy, reducing noise reflection and transmission.

[0056] The sound insulation shell 9 is welded to the inner wall surface of the electric spindle housing 1 , and the sound absorbing cotton 6 is adhesively connected to the inner wall of the sound insulation shell 9 . The sound absorbing cotton 6 is glass fiber cotton.

[0057] Specifically, such as Figure 1-3 As shown, the internal structure of glass fiber wool has low density, many pores, and multi-layer insulation. These characteristics help dissipate and absorb sound waves. When sound waves pass through glass fiber wool, they are reflected and scattered multiple times between the pores and fibers within it, thereby dissipating sound energy and achieving the sound absorption effect.

[0058] Instructions for use: When the electric spindle body 8 is running, the sealing layer 7 inside the dustproof component 3 at the joint between the electric spindle body 8 and the electric spindle housing 1 can fit tightly on the wall of the slot 402 without leaving any gaps. When the fixing seat 4 is fixed to the electric spindle housing 1 by the pin 5, the sealing layer 7 will be squeezed, further enhancing its sealing effect, thereby achieving effective isolation of dust, preventing dust from entering the interior of the electric spindle, reducing dust wear on the spindle components, and extending the service life of the equipment. When the electric spindle body 8 is running, the sound insulation shell 9 serves as the first layer of sound insulation barrier, which can effectively isolate the noise generated by the electric spindle body 8 from propagating outward, and the sound-absorbing cotton 6 can further absorb and transform the noise that penetrates the sound insulation shell 9, thereby achieving a noise reduction effect when the electric spindle is running and reducing noise pollution to the surrounding environment.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
