Description

Technical Field

[0001] This utility model relates to the field of grinding and processing technology, specifically to a rotary grinding machine for processing ferrite magnetic cores. Background Technology

[0002] Ferrite cores are soft magnetic material components made from ferrite powder with a specific formula through pressing and sintering. Sintered ferrite cores often have problems such as dimensional deviations, deformation, surface roughness, and micro oxide layers or burrs formed during the sintering process. Therefore, they need to be ground to remove defects and burrs from their outer surface. However, although existing grinding equipment can grind ferrite cores, the wear of the grinding wheel will affect the processing accuracy and surface quality, requiring frequent dressing or replacement, affecting the stability of continuous processing, and causing deviations in the grinding process. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a rotary grinding machine for ferrite core processing that is simple in structure, reasonably designed, and easy to use. The machine rotates around the ferrite core by driving a grinding wheel, and moves the grinding wheel to fit the ferrite core, thereby uniformly grinding the surface of the ferrite core. During the grinding process, the ferrite core is in a positioned state, which improves the grinding quality.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a processing table, a magnetic core body disposed on the upper side of the processing table, and a grinding mechanism disposed on one side of the magnetic core body; it also includes:

[0005] The fixing frame is an inverted "U" shaped structure. The fixing frame is set on the upper side of the processing table, and the vertical ends of the left and right sides of the fixing frame are fixed on the processing table.

[0006] A fixed platform is fixedly installed in the middle of the inner top surface of the fixed frame; a threaded rod is threaded through the fixed platform, and the upper end of the threaded rod is threaded through the horizontal end of the fixed frame.

[0007] A limiting platform is fixedly installed at the bottom end of the threaded rod and is in contact with the upper side of the magnetic core body; a insertion platform is fixedly installed at the bottom end of the limiting platform and is inserted into the central hole of the magnetic core body.

[0008] A rotating ring is screwed onto the outside of a fixed platform via a bearing, and a rotating gear ring is fitted and fixed onto the rotating ring.

[0009] The rotating motor is fixedly mounted on the horizontal end of the fixed frame by a motor bracket, and the rotating motor is located on the right side of the threaded rod. After the output shaft of the rotating motor passes through the horizontal end of the fixed frame, a rotating gear is provided, and the rotating gear meshes with the rotating gear ring.

[0010] The telescopic frame is located on the lower side of the rotating gear ring, and the grinding motor in the grinding mechanism is located on the telescopic frame.

[0011] With the above technical solution, the magnetic core body is placed on the processing table. The threaded rod is manually rotated, which drives the limiting table to move downward until the bottom of the limiting table is tight to the upper surface of the magnetic core body. The insertion table is inserted into the magnetic core body. The telescopic frame drives the grinding mechanism to contact the outer wall of the magnetic core body and starts the rotating motor to make the rotating gear rotate to rotate the rotating gear ring. This causes the grinding mechanism to rotate around the screw connection center between the rotating ring and the fixed table to perform grinding operation on the outer wall of the magnetic core body.

[0012] As a further improvement of this utility model, the telescopic frame is composed of a fixed frame and a movable frame. The fixed frame is fixedly installed on the outer ring wall of the rotating ring and is located on the lower side of the rotating gear ring. The upper horizontal end of the movable frame passes through the fixed frame, and the grinding motor in the grinding mechanism is located on the lower horizontal end of the movable frame. The bottom of the fixed frame has a slot, and a moving block slides through the slot. The upper side of the moving block is connected to the bottom of the upper horizontal end of the movable frame. An adjusting motor is installed at the bottom of the fixed frame through a motor bracket. The adjusting motor is located on the side away from the vertical end of the movable frame. A lead screw is installed on the output end of the adjusting motor, and the lead screw is threaded through the moving block.

[0013] Through the above technical solution design, the lower horizontal end of the movable frame supports the grinding mechanism, and by starting the adjusting motor, the lead screw is rotated, which drives the moving block to move the grinding mechanism until the grinding wheel in the grinding mechanism is set to fit against the outer wall of the magnetic core body.

[0014] As a further improvement of this utility model, the front and rear sides of the fixed frame are both provided with support shafts by bearings, and rotating parts are sleeved and fixed on the support shafts. The front and rear sides of the vertical end of the movable frame are both fixed with connecting shafts, and the connecting shafts slide through the moving grooves opened in the rotating parts.

[0015] With the above technical solution design, when the movable frame moves, the connecting shaft moves in the moving groove, and the rotating parts rotate around the screw connection center of the support shaft, which strengthens the stability of the movable frame when it moves.

[0016] As a further improvement of this utility model, a support ring is sleeved and fixed on the fixed platform, and an annular groove is opened on the upper side of the support ring; a rotating ring is provided on the upper side of the inner ring wall of the rotating ring, the rotating ring is in contact with the support ring, and an annular rail is fixedly provided at the bottom of the rotating ring, and the annular rail is rotatably disposed in the annular groove.

[0017] The rotating ring is supported by the above technical solution design.

[0018] As a further improvement of this utility model, the upper side of the processing table is provided with a bottom support platform, the magnetic core body is in contact with the bottom support platform, and a boss is provided in the middle of the upper side of the bottom support platform. The central axis of the boss and the central axis of the insertion platform are on the same axis, and the boss is inserted into the central hole of the magnetic core body.

[0019] The above technical solution design strengthens the stability of the magnetic core body during the grinding process.

[0020] As a further improvement of this utility model, a connecting platform is fixedly provided at the bottom of the bottom support platform, and the connecting platform is screwed into the processing table, with the bottom of the bottom support platform in contact with the processing table.

[0021] Through the above technical solution design, different base support platforms are used to support the magnetic core body according to its different specifications.

[0022] The working principle of this utility model is as follows: First, the connecting platform is rotated and inserted into the processing table until the bottom support platform abuts against the processing table. The magnetic core body is then fitted onto the boss, with the bottom of the magnetic core body contacting the bottom support platform. Then, the threaded rod is manually rotated to move the limiting platform downwards until it abuts against the magnetic core body, and the insertion platform is inserted downwards into the magnetic core body, thereby limiting the magnetic core body. The adjusting motor is started to rotate the lead screw, which drives the moving block, causing the movable frame to move the grinding mechanism until the grinding wheel in the grinding mechanism is in contact with the outer wall of the magnetic core body. The grinding motor in the grinding mechanism is started to allow the grinding wheel to grind the surface of the magnetic core body. Finally, the rotating motor is started to rotate the rotating gear to mesh with the rotating gear ring, causing the rotating gear ring to drive the rotating ring to rotate around the center of rotation between the rotating ring and the fixed table, thus driving the grinding wheel to rotate around the magnetic core body and grind its outer wall.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The central axes of the limiting platform, insertion platform, bottom support platform, and boss are the same central axis to achieve the limiting and positioning of the magnetic core body, so that it is in a positioned state during the grinding process and avoids the phenomenon of displacement during the grinding process.

[0025] 2. The rotating ring is supported by bearings, and the rotating ring is rotated by the meshing of the rotating gear and the rotating gear ring. This drives the grinding mechanism to rotate around the magnetic core body, thereby realizing the grinding operation on its outer wall.

[0026] 3. By driving the movable frame, the position of the grinding wheel can be changed so that it fits the outer wall of the magnetic core body, making it suitable for magnetic core bodies of different specifications. Attached Figure Description
