Description

Technical Field

[0001] The utility model relates to the technical field of magnetic ring chamfering, in particular to a magnetic ring inner circle chamfering device. Background Art

[0002] Permanent ferrite rings are widely used in the electroacoustic and home appliance industries as magnetic field sources, providing a constant magnetic field. To enhance the product's surface magnetic force and mechanical strength, iron sheets are attached to the ring's surface. However, this process can cause the inner edges of the ring to chip and break, creating an assembly gap with the iron sheet and affecting the magnetic field's sealing properties. Therefore, chamfering the inner edges of the ring is necessary to prevent this problem. The key production processes for permanent ferrite rings are: ball milling - forming - sintering - grinding - cleaning - and sorting.

[0003] Currently, there are two main methods for chamfering the inner circle of permanent magnet ferrite rings in the industry: one is to achieve chamfering of the formed green body through the design of the forming mold, but the formed chamfer has defects such as burrs and unevenness at the chamfer position, which cannot meet the requirements of high-precision chamfering; the other is to manually chamfer the magnetic ring on a high-speed rotating grinding wheel. This method has high labor costs, low chamfering efficiency, and great safety hazards.

[0004] The invention with publication number CN113894643A discloses a quartz ring inner circle chamfering machine and its use method. The device uses a clamping jaw assembly to simulate human hands to fix the magnetic ring, and then uses a chamfering grinding wheel to chamfer the inner circle of the magnetic ring. However, the device requires manual installation of the magnetic ring into the clamping jaw assembly. There is no magnetic ring input and output device, so automatic chamfering cannot be achieved, and the chamfering efficiency is very low. Utility Model Content

[0005] The purpose of the utility model is to solve the defects in the prior art and provide a magnetic ring inner circle chamfering device to realize automatic chamfering of the magnetic ring and improve the efficiency of the magnetic ring inner circle chamfering.

[0006] To achieve the above-mentioned purpose, the utility model provides a magnetic ring inner circle chamfering device, comprising a feed channel, a chamfering grinding wheel assembly, a moving assembly, a blocking assembly and a discharge channel;

[0007] The moving assembly includes a moving drive and a moving track arranged at the movable end of the moving drive. The moving drive is used to drive the moving track towards or away from the chamfering grinding wheel assembly. The feed channel, moving track and discharge channel are connected in sequence. The blocking assembly is used to keep the magnetic ring in the moving track.

[0008] The magnetic ring inner circle chamfering device can be installed between the magnetic ring grinding machine and the cleaning machine. The feed channel is used to connect the magnetic ring grinding machine and the moving component, the discharge channel is used to connect the moving component and the cleaning machine, and the moving track is used to connect the feed channel and the discharge channel. One side of the moving track is fixed on the moving drive.

[0009] The magnetic ring enters the feed channel from the front grinding process. When it enters the moving track, the blocking component starts working to block the magnetic ring in the moving track. The mobile drive starts working, driving the moving track and the magnetic ring in the moving track forward and contacting the chamfering grinding wheel to complete the chamfering of the inner circle of the magnetic ring. The blocking component retreats, and at the same time, the mobile drive drives the moving track and the magnetic ring backward until the moving track docks with the discharge channel. After the magnetic ring rolls out of the moving track, it enters the rear-end cleaning process through the discharge channel. The magnetic ring inner circle chamfering device of the utility model can realize automatic chamfering, improve the efficiency of the magnetic ring inner circle chamfering, can work stably for a long time, and has low equipment cost and energy consumption.

[0010] Optionally, a chamfering circular hole is provided on the side wall of the movable track adjacent to the chamfering grinding wheel assembly.

[0011] A chamfering hole is formed on the side of the moving track away from the moving drive. The diameter of the chamfering hole is between the outer diameter and the inner diameter of the magnetic ring. When the moving drive is driven forward, the magnetic ring on the moving track can contact the chamfering grinding wheel assembly through the chamfering hole, and the magnetic ring completes the inner chamfer.

[0012] Optionally, the blocking assembly includes a blocking drive and a blocking plate, and the blocking plate is connected to the driving end of the blocking drive.

[0013] The blocking drive drives the blocking plate to block the end of the moving track to block the magnetic ring in the moving track. After the magnetic ring is chamfered, the blocking drive drives the blocking plate to move away from the end of the moving track, allowing the magnetic ring in the moving track to pass through the discharge channel and enter the rear-end cleaning process.

[0014] Optionally, the chamfering grinding wheel assembly includes a grinding wheel drive and a chamfering grinding wheel, the chamfering grinding wheel is connected to the driving end of the grinding wheel drive, and the chamfering grinding wheel is located on one side of the movable track.

[0015] The grinding wheel drive can drive the chamfering grinding wheel to rotate at high speed, and the rotation direction of the chamfering grinding wheel is consistent with the direction of the magnetic ring passing. The chamfering grinding wheel is a spherical grinding wheel with a grinding wheel shaft. The entire spherical surface of the spherical grinding wheel is a grinding surface, and the grinding efficiency is high.

[0016] Optionally, the grinding wheel drive is connected to the chamfering grinding wheel through a coupling to ensure that the grinding wheel drive drives the chamfering grinding wheel to rotate.

[0017] Optionally, a cooling pipe for dripping cooling liquid onto the chamfering grinding wheel is further provided on one side of the chamfering grinding wheel, and the cooling pipe is connected to the cooling liquid delivery device.

[0018] The grinding wheel drive drives the chamfering grinding wheel to rotate at high speed. A cooling pipe is installed behind the chamfering grinding wheel to provide a small stream of water. After flowing to the spherical surface of the chamfering grinding wheel, a water film can be generated on the surface of the high-speed rotating chamfering grinding wheel to cool the chamfering grinding wheel and remove dust generated by chamfering, thereby ensuring the heat dissipation effect of the chamfering grinding wheel.

[0019] Optionally, the magnetic ring inner chamfering device further includes a position sensor for detecting the position of the magnetic ring, and the position sensor is electrically connected to the mobile drive and blocking components respectively.

[0020] The magnetic ring enters the feed channel from the front grinding process and enters the moving track through the position sensor. The position sensor is triggered and the blocking drive starts working, driving the blocking plate forward to block the rear end of the moving track.

[0021] Optionally, the magnetic ring inner circle chamfering device further includes a support platform, the moving component and the blocking component are both arranged on the support platform, and the height and inclination angle of the support platform are adjustable.

[0022] A support platform is positioned on either side of the feed and discharge channels, housing the position sensor, accelerator nozzle, movable assembly, and barrier assembly. Below the support platform are telescopic support columns, allowing for adjustable height and tilt angles. This ensures the position of the position sensor, accelerator nozzle, movable assembly, and barrier assembly can be adjusted to the position of the feed and discharge channels.

[0023] Optionally, the feed channel, the movable track and the discharge channel are all arranged at an angle, and the feed channel, the movable track and the discharge channel are connected in sequence from high to low.

[0024] The feed channel is supported by a feed support rod with adjustable height, and the discharge channel is supported by a discharge support rod with adjustable height. By adjusting the height of the feed support rod, the discharge support rod and the support column, the height and inclination angle of the feed channel, the moving track and the discharge channel can be adjusted, so that the feed channel, the moving track and the discharge channel are inclined higher in the front and lower in the back, and are smoothly connected to each other, so that the magnetic ring can pass freely and quickly.

[0043] See also Figure 1-7 According to an embodiment of the present invention, a magnetic ring inner circle chamfering device includes a feed channel 2, a chamfering grinding wheel assembly 3, a moving assembly 6, a blocking assembly 7 and a discharge channel 8;

[0044] The moving assembly 6 includes a moving drive 61 and a moving track 62 arranged at the movable end of the moving drive 61. The moving drive 61 is used to drive the moving track 62 to approach or move away from the chamfering grinding wheel assembly 3. The feed channel 2, the moving track 62 and the discharge channel 8 are connected in sequence, and the blocking assembly 7 is used to keep the magnetic ring 9 in the moving track 62.

[0045] Specifically, the magnetic ring internal chamfering device can be installed between a magnetic ring grinding machine and a cleaning machine. It includes a workbench 1, upon which the feed channel 2, chamfering grinding wheel assembly 3, moving assembly 6, blocking assembly 7, and discharge channel 8 are all mounted. The feed channel 2 connects the magnetic ring grinding machine and moving assembly 6, while the discharge channel 8 connects the moving assembly 6 and the cleaning machine. The width of the feed channel 2 and discharge channel 8 is equal to the thickness of the magnetic ring 9 plus 2 mm. A movable rail 62 connects the feed channel 2 and discharge channel 8, one side of which is fixed to the movable drive 61.

[0046] The magnetic ring 9 enters the feed channel 2 from the front grinding process. When it enters the movable track 62, the blocking assembly 7 starts to operate, blocking the magnetic ring 9 within the movable track 62. The movable drive 61 starts to operate, driving the movable track 62 and the magnetic ring 9 within the movable track 62 forward and into contact with the chamfering grinding wheel 34, completing the chamfering of the inner circle of the magnetic ring. The blocking assembly 7 retreats, and the movable drive 61 simultaneously drives the movable track 62 and the magnetic ring 9 backward until the movable track 62 mates with the discharge channel 8. After the magnetic ring 9 rolls out of the movable track 62, it passes through the discharge channel 8 and enters the rear cleaning process.

[0047] The magnetic ring inner circle chamfering device of the present invention can realize automatic chamfering, improve the efficiency of chamfering the inner circle of the magnetic ring 9, can work stably for a long time, and has low equipment cost and energy consumption.

[0048] See also Figure 5 and 6 In some embodiments of the present invention, a chamfering circular hole 63 is opened on the side wall of the movable track 62 adjacent to the chamfering grinding wheel assembly 3.

[0049] The length of the movable track 62 is the same as the diameter of the magnetic ring 9, and its width is equal to the thickness of the magnetic ring 9 plus 2 mm. A chamfered circular hole 63 is defined on the side of the movable track 62 facing away from the movable drive 61. The diameter of the chamfered circular hole 63 lies between the outer and inner diameters of the magnetic ring 9. When the movable drive 61 propels the movable track 62 forward, the magnetic ring 9 on the movable track 62 contacts the chamfering grinding wheel assembly 3 through the chamfered circular hole 63, completing the inner chamfering of the magnetic ring 9. The sidewall of the movable track 62 with the chamfered circular hole 63 is higher than the other sidewall, preventing the magnetic ring 9 from falling off the movable track 62.

[0050] See also Figure 7 In some embodiments of the present invention, the blocking assembly 7 includes a blocking drive 71 and a blocking plate 72 , and the blocking plate 72 is connected to the driving end of the blocking drive 71 .

[0051] The blocking drive 71 drives the blocking plate 72 to block the end of the moving track 62, which is used to block the magnetic ring 9 in the moving track 62. After the magnetic ring 9 is chamfered, the blocking drive 71 drives the blocking plate 72 to move away from the end of the moving track 62, so that the magnetic ring 9 in the moving track 62 passes through the discharge channel 8 and enters the rear-end cleaning process.

[0052] Both the moving drive 61 and the blocking drive 71 are cylinders. The stroke of the blocking drive 71 must be greater than that of the moving drive 61. During installation, ensure that when both cylinders are moving forward, the blocking plate 72 can block the magnetic ring 9 in the moving track 62. When both cylinders are moving backward, the blocking plate 72 cannot block the magnetic ring 9 in the moving track 62. A delay is set between the forward movement of the blocking drive 71 and the forward movement of the moving drive 61 to ensure that the moving drive 61 will not move forward until all the magnetic rings 9 have entered the moving track 62.
