[0021] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0022] The embodiment of the present application discloses a new type of air compressor main frame. Figure 1 and Figure 2 , including a main frame body 1, the main frame body 1 includes a supporting portion 11, a connecting portion 12 installed on the top surface of the supporting portion 11 and a positioning portion 13 installed on the top surface of the connecting portion 12, and a cylinder positioning member 2 is installed on the positioning portion 13 to improve the stability of the cylinder on the main frame body 1 and reduce the possibility of eccentricity or unstable installation of the cylinder.

[0023] Reference Figure 1 and Figure 2In the embodiment of the present application, the support portion 11, the connection portion 12 and the positioning portion 13 are integrally formed to improve the strength and stability of the main frame body 1. The support portion 11 is provided with a support plate 17 connected to one side of the connection portion 12 in the height direction, and the support plate 17 further improves the connection strength between the connection portion 12 and the support portion 11; the connection portion 12 is provided with support plates 2 8 located on both sides of the positioning portion 13, and the support plates 2 8 reduce the influence of the gravity of the components when the positioning portion 13 is installed, improve the support strength of the positioning portion 13 and the connection portion 12, and reduce the possibility of eccentricity or unstable installation of the cylinder. In the embodiment of the present application, the support plate 17, the support plate 28 and the main frame body 1 are integrally formed to save installation time and simplify the installation steps.

[0024] Reference Figure 1 and Figure 2 The cylinder positioning member 2 includes a sleeve 21 mounted on the positioning portion 13 and a positioning ring 22 fixedly mounted on the top surface of the sleeve 21. The positioning ring 22 and the sleeve 21 are integrally formed in the embodiment of the present application to improve the connection strength between the positioning ring 22 and the sleeve 21. The positioning portion 13 is provided with a through hole for the sleeve 21 to pass through. The inner diameter of the through hole is consistent with the outer diameter of the sleeve 21, which improves the stability of the sleeve 21 on the positioning portion 13. The outer diameter of the positioning ring 22 is larger than the outer diameter of the sleeve 21, which improves the stability of the sleeve 21 on the positioning portion 13.

[0025] Reference Figure 1 and Figure 2 In the embodiment of the present application, the main frame body 1 is die-cast, and the installation position of the cylinder positioning member 2 is anodized to improve the accuracy and wear resistance. In the embodiment of the present application, the cylinder positioning member 2 and the main frame body 1 can be integrally formed to further improve the connection stability between the main frame body 1 and the cylinder positioning member 2.
