Description

Technical Field

[0001] The invention relates to the technical field of electromagnet bases, in particular to a super weight-reducing electromagnet base. Background Art

[0002] The existing super-weight-reducing electromagnet bases on the market use conventional lathe processing technology to machine the coil ring grooves and the surface of the core and the fitting surface of the armature (hereinafter referred to as the slide plate). This type of super-weight-reducing electromagnet base does not have the advantages of hollow inner wall weight reduction and material saving. During assembly, a friction plate is placed on the slide plate surface and connected to the fixed connection plate through three columns, namely the spacer. Due to the small outer diameter of the spacer, it is difficult to ensure the extremely small tolerance of the height of the spacer required for batch production. The processed spacer needs to be fully sorted and assembled. Otherwise, the uneven assembly air gap will cause instability in braking performance. Conventional electromagnets are difficult to achieve high assembly accuracy even through batch-sorted spacer assembly and connection. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a super-weight-reducing electromagnet base, which reduces weight and saves materials, has the advantages of heat dissipation, removal of friction dust, high assembly precision, uniform electromagnetic air gap, and stable pull-in voltage.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a super weight-reducing electromagnet base, which is characterized by comprising a base body, wherein the base body is a cylindrical hollow structure, and one end is open; an iron core is arranged in the middle of the base body; The side wall of the base body is provided with a wire outlet slot opening, and the inner side wall of the base body is provided with a plurality of slide plate fitting surfaces, a plurality of degassing sinks and a plurality of inner wall slots of different depths; A plurality of fixing plate mounting surfaces and a plurality of concave table surfaces are arranged on the end surface of the side wall of the open end of the base body.

[0005] The beneficial effects of the present invention are as follows: the super-weight-reducing electromagnet base of the present invention reduces weight and saves materials, has the advantages of heat dissipation, removal of friction dust, high assembly precision, uniform electromagnetic air gap, and stable pull-in voltage.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

DETAILED DESCRIPTION

[0008] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0009] like Figure 1-Figure 3 As shown, a super weight-reducing electromagnet base comprises a base body 1, wherein the base body 1 is a cylindrical hollow structure with one end being open; an iron core 7 is arranged in the middle of the base body 1; The side wall of the base body 1 is provided with a wire outlet slot opening 2, and the inner side wall of the base body 1 is provided with 12 slide plate fitting surfaces 5, 4 degassing sinks 6 and 12 inner wall slots 4 of different depths; The open end side wall end surface of the base body 1 is provided with 3 or 4 sections of fixed connection plate mounting surfaces 3 and 3 or 4 sections of sunken table surfaces 8, and the sunken table surfaces 8 have the functions of effectively dissipating heat and removing friction dust.

[0010] The present invention hollows out the rest of the electromagnet base except for 12 slide fitting surfaces 5, 3 or 4 degassing platforms 6, 2 cotter pin holes and 2 switch fastening screw holes, so that the electromagnet base is lightest without losing the magnetic properties of the electromagnet base, thereby achieving the purpose of reducing weight, saving materials and reducing costs.

[0011] The base structure has high installation accuracy. After the fixed connection plate, slide plate and friction plate are assembled, the air gap when the electromagnet is working can be effectively guaranteed to be uniform. During braking, the contact area between the two end surfaces of the friction plate and the end surface of the fixed connection plate and the slide plate is greatly increased, and the braking effect is more stable. The defects of poor assembly accuracy, uneven air gap and poor braking stability caused by the low precision of the spacer sleeve in the conventional connection with the spacer sleeve are solved.

[0012] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
