Problems solved by technology

When processing E-type magnetic cores with a pass-through grinder, some air gaps are very deep, and grinding them off once will have an impact on the performance of E-type magnetic cores, so it needs to be grinded back and forth twice before they can be ground. For example, if the air gap is 2.0 mm, first grind 1.5mm for the first time, and then grind 0.5mm for the second time to meet the requirements, which is time-consuming and labor-intensive, and the through-type grinder cannot be fully utilized

Embodiment 1

[0020] Such as figure 1 and figure 2 As shown, a double-air-gap grinding head pass-through grinding machine for grinding magnetic cores includes a main shaft grinding wheel 1, a first air-gap grinding wheel 2 arranged in front of the main shaft grinding wheel 1, and a second air-gap grinding wheel is arranged behind the main shaft grinding wheel 1 3. The centers of the first air-gap grinding wheel 2 and the second air-gap grinding wheel 3 are on the same horizontal line, and the diameter of the second air-gap grinding wheel 3 is larger than the diameter of the first air-gap grinding wheel 2 . Keep the bottom end position of the second air gap grinding wheel 3 lower than the bottom end position of the first air gap grinding wheel 2 .

[0021] In actual operation, such as image 3 , is the unprocessed E-shaped magnetic core, after the first air-gap grinding wheel 2, the middle foot 12 of the E-shaped magnetic core is ground off by 1.5mm to form as Figure 4 State, and then ...

Embodiment 2

[0023] Such as Figure 7 and Figure 8 As shown, a double-air-gap grinding head pass-through grinding machine for grinding magnetic cores includes a main shaft grinding wheel 1, a first air-gap grinding wheel 2 arranged in front of the main shaft grinding wheel 1, and a second air-gap grinding wheel is arranged behind the main shaft grinding wheel 1 3. The diameter of the first air-gap grinding wheel 2 is the same as that of the second air-gap grinding wheel 3 , and the center of the second air-gap grinding wheel 3 is lower than the center of the first air-gap grinding wheel 2 . Keep the bottom end position of the second air gap grinding wheel 3 lower than the bottom end position of the first air gap grinding wheel 2 . Compared with Embodiment 1, the second air-gap grinding wheel 2 in this embodiment does not need to use a large-diameter grinding wheel, which saves costs.

Abstract

The invention provides a dual air gap grinding head through grinding machine for grinding a magnetic core, which comprises a main shaft grinding wheel and a first air gap grinding wheel arranged in front of the main shaft grinding wheel, wherein a second air gap grinding wheel is arranged at the back of the main shaft grinding wheel. The dual air gap grinding head through grinding machine can finish processing the E-shaped magnetic core through once passing so as to save the time and cost and ensure the product performance of the E-shaped magnetic core.

Description

technical field [0001] The invention relates to a through-type grinder with double air gap grinding heads for grinding magnetic cores. Background technique [0002] At present, when processing E-type magnetic cores, the middle leg of the E-type magnetic core needs to be ground a little deeper than the side legs. The grinding of the side legs is commonly known as flattening, and the grinding of the middle leg is commonly known as opening the air gap. In the prior art, a through-type grinding machine is required to process the E-shaped magnetic core. The main shaft grinding wheel in the grinding machine is flattened, and an air gap grinding wheel is used to open the air gap. When processing E-type magnetic cores with a pass-through grinder, some air gaps are very deep, and grinding them off once will have an impact on the performance of E-type magnetic cores, so it needs to be grinded back and forth twice before they can be ground. For example, if the air gap is 2.0 mm, first...
