Description

Technical Field

[0001] The utility model relates to the field of magnetic core production, and more specifically to a clamping assembly for grinding magnetic cores. Background Art

[0002] A magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. The surface of the magnetic core is relatively rough after being pressed and formed, so it is necessary to grind the magnetic core to make the surface smooth, which will affect the subsequent use of the magnetic core. There are many types of magnetic core shapes, and the common magnetic cores are ring-shaped and E-shaped. The ring-shaped magnetic core has a circular inner surface, which makes it difficult to grind. The existing inner surface grinding of the ring-shaped magnetic core can only be done manually by loading and unloading one by one. After grinding, the magnetic core is removed, which is inefficient and cannot form continuous processing. Utility Model Content

[0024] Example:

[0025] See also Figure 1-Figure 5 As shown, a clamping assembly for grinding a magnetic core comprises a workbench 1, a support platform 8 is arranged at the center of the upper surface of the workbench 1 to support the center of a conveyor belt 111 to ensure stability during grinding at the center position, mounting plates 10 are symmetrically arranged on both sides of the workbench 1, a pulley roller 11 is installed between two mounting plates 10 on the same side through a bearing, the upper surface of the pulley roller 11 is at the same height as the upper surface of the support platform 8, a conveyor belt 111 is sleeved on the surfaces of the two pulley rollers 11, the conveyor belt 111 is wrapped around the upper and lower surfaces of the workbench 1, a fixed block A12 is evenly arranged on the front side of the surface of the conveyor belt 111, a fixed block B15 is evenly arranged on the rear side of the surface of the conveyor belt 111, the fixed block A12 and the fixed block B15 correspond to each other one by one, a notch is opened on the side where the fixed block A12 and the fixed block B15 are close to each other, and the magnetic core is placed between the two notches. A gap larger than the inner circle of the magnetic core is left between the fixed block A12 and the fixed block B15, so that the magnetic core is in a suspended state. At the same time, there is no obstacle below the inner circle of the magnetic core, so that the grinding wheel shaft 6 can move down beyond the lower surface of the annular magnetic core. The magnetic core is suspended above the conveyor belt 111. An adjusting clamp 13 is slidably installed in the notch of the fixed block A12. A pitch adjusting screw 14 is screwed through the inner side of the fixed block A12. The end of the pitch adjusting screw 14 is installed on the adjusting clamp 13 through a bearing. The position of the adjusting clamp 13 is controlled by screwing the pitch adjusting screw 14 at the front end, so as to adapt to the clamping work of magnetic cores of different sizes. A movable clamp 16 is slidably installed on the notch side of the fixed block B15. The adjusting clamp 13 and the movable clamp 16 are respectively placed on both sides of the magnetic core, and the magnetic core is clamped and fixed by the adjusting clamp 13 and the movable clamp 16.

[0026] Please refer to Figure 3 and Figure 5 As shown, a connecting rod 17 is laterally arranged on the side of the movable splint 16 away from the fixed block A12, a storage hole 18 is opened on the rear surface of the fixed block B15, and an extrusion head 19 is arranged on the end of the connecting rod 17 away from the movable splint 16. The extrusion head 19 is placed on the inner side of the storage hole 18. The extrusion head 19 and the movable splint 16 can move synchronously. The rear end of the extrusion head 19 exceeds the end face of the fixed block B15 and can move forward after being squeezed.

[0027] Among them, an extrusion plate 9 is fixed on the rear side of the upper surface of the workbench 1. The extrusion plate 9 is set as an inclined surface near the feed end to facilitate the gradual extrusion of the extrusion head 19. The rear end of the extrusion head 19 is set to a hemispherical shape to reduce friction. The rear end of the extrusion head 19 corresponds to the position of the extrusion plate 9. When it moves to the center position, the inner adjustment clamp 13 and the movable clamp 16 can be squeezed by each other to fix the central magnetic core. A spring 20 is sleeved on the surface of the connecting rod 17. The spring 20 is placed on the inner side of the storage hole 18. One end of the spring 20 is in contact with the front end surface of the extrusion head 19. The spring 20 always has a backward thrust on the extrusion head 19, so that the magnetic core is in a clamping state when it has not entered the central area or has been removed from the central area, so as to facilitate loading and unloading.

[0028] Please refer to Figure 1 and Figure 2 As shown, a column 2 is vertically fixed on the rear side of the upper surface of the workbench 1, a hydraulic cylinder 3 is fixed on the top of the column 2, an extension plate 4 is slidably installed on the front side of the column 2, the rear end of the extension plate 4 is installed on the output end of the hydraulic cylinder 3, a driving motor 5 is arranged on the front end of the upper surface of the extension plate 4, a grinding wheel shaft 6 is installed on the output end of the driving motor 5, the grinding wheel shaft 6 is placed under the extension plate 4, the grinding wheel shaft 6 is suspended just above the center of the conveyor belt 111, the diameter of the grinding wheel shaft 6 is matched with the inner circle of the annular magnetic core, and the conveyor belt 111 moves intermittently, and makes a short stop when the magnetic core moves to the bottom of the grinding wheel shaft 6.

[0029] Please refer to Figure 1 As shown, a discharging guide plate 7 is obliquely provided at the discharging end of the workbench 1, and the discharging guide plate 7 is placed under the pulley roller 11 to guide the discharging of the polished annular magnetic core.

[0030] Working principle: The staff loads the material from the side away from the discharge guide plate 7. Due to the existence of the spring 20, the extrusion head 19 always has a backward force, and pulls the movable clamping plate 16 backward, increasing the distance between the adjustment clamping plate 13 and the movable clamping plate 16. At this time, the distance between the two is increased to facilitate loading and unloading of the front and rear ends. The annular magnetic core is placed between the adjustment clamping plate 13 and the movable clamping plate 16, and the motor drives the pulley roller 11 on one side to rotate, which can then drive the conveyor belt 111 to move. When the magnetic core moves to the center of the workbench 1, the conveyor belt 111 is supported by the support table 8 below, and at the same time, the rear side The extrusion plate 9 will squeeze the extrusion head 19, causing the extrusion head 19 to shrink into the storage hole 18, and then the movable splint 16 will move forward to squeeze and fix the magnetic core in the middle position. When the magnetic core moves to the bottom of the grinding wheel shaft 6, the driving motor 5 can drive the grinding wheel shaft 6 to rotate at high speed, and the hydraulic cylinder 3 can control its downward movement, so that the grinding wheel shaft 6 enters the inner circle of the annular magnet for grinding. When it continues to move beyond the range of the extrusion plate 9, the movable splint 16 moves backward due to the stored force of the spring 20. At this time, the magnetic core is relaxed, and when it rotates to the end, it can automatically fall to the inside of the discharge guide plate 7.

[0031] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
