[0010] Compared with the prior art, the beneficial effects produced by the present invention are:

[0011] 1. This utility model uses two semicircular cross-section unit blocks to form the cylinder, reducing mold development costs and shortening the material response time of the machine base production. Two or more cylinders are then spliced ​​along the length to form the main body of the extended machine base, eliminating the need for a separate extended machine base mold and providing greater flexibility.

[0012] 2. The utility model opens a through-port to connect the adjacent water channels in the cylinder, adopts two or more cylinders to be spliced ​​along the length direction to form the main body of the extended version of the machine base, and then arranges annular sealing plates on the outer sides of the adjacent cylinders and the cylinders at both ends to improve the fluidity and sealing of the water channels in the machine base, reduce the probability of poor fluidity that may occur in the extended version of the machine base during casting, and reduce the defect rate caused by poor fluidity.

DETAILED DESCRIPTION

[0021] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0022] In the description of the present invention, it should be noted that if terms indicating orientation or positional relationships such as "upper", "lower", "inside", "outside", "head", "tail", "end", and "bottom" appear, they are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0023] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 , a driving motor base 10 manufactured by welding, the main body of the base 10 includes at least one cylinder 11 with a circular ring cross section, and the cylinder 11 is composed of two unit blocks 12 with semicircular ring cross sections welded together, and each unit block 12 is provided with a plurality of water channels 20 inside. In this embodiment, the unit block 12 is manufactured by a stretching profile mold, and only the mold of the unit block 12 needs to be opened. The water channels 20 inside the unit block 12 are strip water channels 25 arranged at intervals. The welding surfaces 13 of the two unit blocks 12 are attached to each other and welded into a cylinder 11, and then staggered through-holes 23 are machined at both ends of the cylinder 11 to make adjacent strip water channels 25 communicate with each other, forming a complete set of arched water channels 24 in one cylinder 11. Specifically, the head end and the tail end of the arched water channel 24 are respectively provided with a water inlet 21 and a water outlet 22.

[0024] Example 1

[0025] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 4 In this embodiment, the main body of the base 10 is composed of a cylindrical body 11, which is suitable for motors of conventional length. The base 10 also includes a water inlet assembly 51 and a water outlet assembly 52 provided on the cylindrical body 11, which correspond to the water inlet hole 21 and the water outlet hole 22 provided in the arched water channel 24, respectively. When in use, the water inlet assembly 51 and the water outlet assembly 52 can be connected to the water inlet pipe and the water outlet pipe. If the length of the base 10 is shorter, after the two unit blocks 12 are processed into the cylindrical body 11, the cylindrical body 11 can be cut to the required length and the through-hole 23 can be opened. There is no need to prepare a separate mold for the shorter unit block 12, which reduces the mold opening cost.

[0026] Reference Figure 2 、 Figure 3 and Figure 5 The base 10 further includes annular sealing plates 30 provided at both ends of the cylinder 11 for sealing the water channel 20 in the cylinder 11. A plurality of mounting feet 40 are provided at the bottom of the base 10. In this embodiment, the conventional version of the base 10 has two mounting feet 40 at the bottom, which facilitates the installation of the base 10 and improves the reliability of the device.

[0027] Example 2

[0028] Reference Figure 5 and Figure 6In this embodiment, two or more cylinders 11 are assembled axially to form the main body of the machine base 10, which can be applied to the extended version of the motor, without the need to open a mold for the extended version of the machine base 10. Specifically, an annular sealing plate 30 is provided on the outer side of the cylinder 11 at both ends, and adjacent cylinders 11 are separated by the annular sealing plate 30. Each cylinder 11 constituting the extended version of the machine base 10 has a complete set of arched water channels 24. In this embodiment, two cylinders 11 are spliced ​​together to form the extended version of the machine base 10. The arched water channels 24 in the two cylinders 11 are independent of each other and correspond to a set of water inlet holes 21 and water outlet holes 22 respectively, and a water inlet assembly 51 and a water outlet assembly 52 are respectively provided outside each cylinder 11, thereby improving the fluidity and sealing of the water channel 20 in the machine base 10, reducing the probability of poor fluidity that may occur in the casting of the extended version of the machine base 10, and reducing the defect rate caused by poor fluidity. In this embodiment, three mounting feet 40 are provided at the bottom of the machine base 10 to share the weight of the machine base 10 and facilitate the installation and placement of the extended version of the machine base 10 .
