[0023] In addition, in the present utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features; in addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0024] The following is combined with Figure 1-5 The utility model is described in further detail.

[0025] See also Figures 1 to 5 The utility model provides a technical solution: a linear motor installation base plate reinforcement structure, including a linear motor core 1 and a wedge-shaped groove base plate 3; the linear motor core 1 is provided with a connection notch 2 at the bottom; a plurality of strip steels 4 are evenly welded in the groove of the wedge-shaped groove base plate 3; the linear motor core 1 is closely connected with the strip steels 4 welded in the groove of the wedge-shaped groove base plate 3 through the connection notch 2; the connection notch 2 of the linear motor core 1 and the strip steel 4 are sealed and reinforced at the connection point by a sealing glue 5 to form a whole. The strip steel 4 is connected to the wedge-shaped groove base plate 3 by welding, which can be done by argon arc welding, arc welding, etc.

[0026] Specifically, in this embodiment, the linear motor core 1 is formed by bonding a plurality of T-shaped silicon steel sheets, and the number and shape of the silicon steel sheets can be changed according to specific circumstances.

[0027] Specifically, in this embodiment, the number of the linear motor cores 1 is one or more, depending on the actual length of the linear motor and equipment requirements.

[0028] Specifically, in this embodiment, the material of the strip steel 4 is low alloy steel, and its material can be other types of steel with high hardness and toughness.

[0029] Specifically, in this embodiment, the number of welded steel bars 4 is 1 or more, and the number is determined by the specific number of the linear motor cores 1 .

[0030] Specifically, in this embodiment, the material of the wedge-shaped groove bottom plate 3 is aluminum alloy.

[0031] Specifically, in this embodiment, the connection notch 2 is wedge-shaped or T-shaped.

[0032] Example:

[0033] like Figures 1 to 5 As shown, a linear motor mounting base plate reinforcement structure includes a linear motor core 1 and a wedge-shaped groove base plate 3; the linear motor core 1 is composed of 8 T-shaped silicon steel sheets bonded together and a connecting notch 2 is provided at the bottom; 6 strip steels 4 are evenly welded in the wedge-shaped groove base plate 3.

[0034] In this embodiment, preferably, the material of the steel strip 4 is low alloy steel; and the welding method is argon arc welding.

[0035] In this embodiment, preferably, the material of the wedge-shaped groove bottom plate 3 is aluminum alloy.

[0036] Preferably, in this embodiment, the linear motor core 1 is butted against the wedge-shaped groove bottom plate 3 through the connecting notch at the bottom and installed together.

[0037] Preferably, in this embodiment, the linear motor core connection notch 2 and the strip steel 4 in the wedge-shaped groove are sealed and reinforced by a sealing glue 5 to form a tight whole.

[0038] The working principle solved by the utility model is as follows: usually, the linear motor core 1 is assembled by adhesive and then directly installed on the base plate. As the linear motor is used for a longer time, the glue ages and falls off, which will cause the core to break, thus affecting the normal use of the linear motor. The structure of the linear motor core 1 and the wedge-shaped groove base plate 3 is strengthened by changing, that is, adding the linear motor core connection notch 2 and the strip steel 4, and the strip steel on the base plate is welded, which is more secure. The structural nesting method of the wedge-shaped groove can lock the linear motor core and the base plate with each other, and at the same time, a sealing glue 5 is added for sealing, so that the connection is tightly connected, thereby increasing the friction. Compared with the conventional gluing method, the utility model will not have the phenomenon of glue aging, which significantly improves the firmness of the linear motor.

[0039] The materials used for the silicon steel sheets, strip steels and wedge-shaped groove bottom plates in the utility model are commonly used materials on the market, are inexpensive, do not require high precision for parts, are easy to process, and are suitable for large-scale batch production.

[0040] Beneficial effects of the utility model:

[0041] The linear motor core can be tightly connected with the strip steel welded in the wedge-shaped groove bottom plate through the connection notch opened at the bottom, and then the interface is sealed with a sealing glue to form a whole. The linear motor core is not easy to break, which greatly enhances the installation strength of the linear motor. The materials used are commonly used materials in the market, with low prices, low requirements on parts precision, easy processing, and suitable for large-scale mass production.

[0042] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the embodiments of the present invention.
