Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, and in particular to a welding fixture for the medium mesh of a magnetic separator. Background Technology

[0002] Magnetic separation equipment refers to equipment that separates magnetic materials from other materials based on their magnetic properties. It is commonly used for screening magnetic minerals such as magnetite. Magnetic separation equipment is also commonly called a magnetic separator or magnetic separation machinery.

[0003] The magnetic media mesh in a magnetic separator is a key component for achieving magnetic separation. Under the action of coils, a high-gradient magnetic field is formed on the mesh, adsorbing ferromagnetic substances in the material. Multiple meshes are filled within the media chamber, arranged in a crisscross pattern. The mesh is made of individual media strips welded and fixed to a central shaft sleeve. By adjusting the orientation of the keyways on the central shaft sleeve, a crisscrossed mesh can be created. However, in actual manufacturing, the following problems often exist:

[0004] 1. During the welding process of the medium strip and the central shaft sleeve, the relative position of the medium strip and the keyway is difficult to determine. As a result, after the assembly is completed, the medium strips of the upper and lower layers of medium mesh are not perpendicular to each other, which results in poor aesthetics and is prone to material blockage during use.

[0005] 2. The spacing between the dielectric strips is generally 15, 20, or 30 mm. During assembly welding, the required gap needs to be measured with a ruler before spot welding. This method is inconvenient for one person, easily leading to uneven spacing, and is labor-intensive and inefficient. Each dielectric mesh assembly requires 3.5 hours of work.

[0006] 3. Manual positioning can easily cause the outer contour of the medium mesh to exceed tolerances. The gap between the medium mesh and the outer cylinder is only 1.5-2mm. To prevent assembly problems, wire cutting of the outer circle is required after welding. The wire cutting process of each medium mesh takes 1-2 hours, which is time-consuming and costly. Summary of the Invention

[0007] The purpose of this utility model is to provide a welding fixture for the medium mesh of a magnetic separator, so as to solve the problems of low production efficiency, high assembly and welding difficulty, poor quality and high cost in the existing medium mesh welding process.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A welding fixture for a magnetic separator's media screen includes a base plate, an outer positioning ring fixedly connected to the base plate, a rotatable positioning pin at the center of the base plate, keyways on the positioning pin and the base plate for inserting flat keys, a set screw hole and an assembly hole on the outer ring, a set screw and a set screw base for rotational fixing outside the set screw hole, a spacer block positioning track on the base plate, and multiple spacers that can be placed within the spacer block positioning track.

[0010] The outer positioning ring is smaller than the barrel size, ensuring that the medium sheet can be smoothly installed into the barrel without the need for wire cutting.

[0011] The spacers are all standard cubes made to the required dimensions.

[0012] The tooling base plate has two keyways, which are positioned either parallel or perpendicular to the positioning track of the spacer block.

[0013] The locating pin is connected to the back of the tooling base plate via a nut.

[0014] The tooling base plate is fixedly connected to a support leg.

[0015] The beneficial effects of this utility model are:

[0016] 1. The use of welding fixtures for the electromagnetic separator's media mesh can eliminate problems such as uneven spacing and non-perpendicular orientation of the media strips, significantly improving the product qualification rate.

[0017] 2. By strictly limiting the outer diameter of the medium mesh, the outer diameter machining process is saved, and the welding workload is reduced. Using the medium mesh welding fixture, the welding time for a single piece is greatly shortened, and there is no need for wire cutting of the outer diameter. Each electromagnetic separator can save 35-40 welding hours and 20-30 machining hours, increasing efficiency by more than 150%, saving a lot of production costs, and improving product quality.

[0018] 3. The medium mesh is placed vertically and horizontally in an alternating pattern, requiring the fabrication of two types of medium mesh with interchangeable bushings. Using the welding fixture of this utility model, by rotating the central positioning pin, the two vertically arranged keyways on the fixture base plate can be used to accurately interchange and position the bushings. There is no need to fabricate multiple fixtures. The spacer blocks can be customized and replaced according to the required spacing size. The medium strips are placed sequentially in the middle of the spacer blocks, the reinforcing ribs are threaded through, and the set screws on both sides are tightened to begin welding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] See Figures 1-3 This utility model provides a welding fixture for the medium mesh of a magnetic separation device.

[0027] A welding fixture for a magnetic separator's media mesh includes a base plate with an outer positioning ring fixedly connected to it. The outer positioning ring is smaller than the material cylinder size to ensure that the media mesh can be smoothly installed into the cylinder, eliminating the need for subsequent wire cutting. A rotatable positioning pin is located at the center of the base plate, connected to the back of the base plate via a nut. Both the positioning pin and the base plate have keyways. Since the media mesh needs to be placed in a staggered arrangement (one longitudinal and one transverse), two keyways are provided, positioned parallel or perpendicular to the positioning track of the spacer block. During use, by tightening the nut and rotating the positioning pin, the key is inserted into the desired keyway and locked in place, accurately positioning the bushing and ensuring the neatness of the longitudinal and transverse media mesh fabrication.

[0028] The outer ring has set screw holes and assembly holes. Set screws and set screw bases are fitted around the set screw holes for rotational fixing. The tooling base plate has spacer block positioning tracks. The welding fixture has multiple spacers that can be placed within these tracks; each spacer is a standard cube made to the required dimensions. In use, the spacers are placed on the base plate positioning tracks. After the medium strip and spacers are arranged sequentially, the reinforcing round steel is inserted into the assembly holes, and the set screws on both sides are tightened to position the medium strip. Welding can then proceed, thus improving welding efficiency and ensuring welding quality.
