Description

Technical Field

[0001] This utility model relates to the field of chamfering device technology, specifically a chamfering device for ferrite cores. Background Technology

[0002] Ferrite cores are a type of high-frequency magnetic material, mainly used in high-frequency transformers (such as switching power supplies and horizontal output transformers), high-frequency magnetic rings (for anti-interference), and so on.

[0003] After the ferrite core is manufactured, it needs to be chamfered. For toroidal ferrite cores, a double-head chamfering machine is generally used. It usually consists of two chamfering cutters and a conveying system. The working principle of the double-head chamfering machine is to feed the material to be processed into the machine through the conveying system and cut it simultaneously by two chamfering cutters inside the machine. During the cutting process, the chamfering cutters will deburr and remove sharp edges from the material, thereby obtaining a smooth chamfer effect.

[0004] When performing chamfering operations on toroidal ferrite cores using a double-headed chamfering machine, a large amount of fine dust is generated. This dust, when dispersed into the air, can affect the health of workers and pollute the environment. Therefore, a ferrite core chamfering device is provided. Utility Model Content

[0005] The purpose of this invention is to provide a ferrite core chamfering device in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ferrite core chamfering device, comprising a worktable, a clamping assembly, a chamfering assembly, and a feeding assembly, wherein the clamping assembly comprises a fixed clamping block, a first pneumatic push rod, and a movable clamping block;

[0007] The fixed clamping block and the first pneumatic push rod are respectively fixedly installed on both sides of the top of the workbench. The movable clamping block is fixed to the output end of the first pneumatic push rod. The movable clamping block is driven to approach the fixed clamping block by the first pneumatic push rod to achieve clamping and fixing of the ferrite core.

[0008] The top of the movable clamp is fixed with a dust suction hood, and the top of the dust suction hood is fixed with a dust suction pipe that is connected to an external suction device. When the ferrite core is beveled by the bevel assembly, the dust suction hood is used to intercept the scattered dust, and the external suction device is used to draw and collect the dust.

[0009] As a further embodiment of this utility model: the chamfering assembly includes a guide rail, a moving table, a chamfering motor, a chamfering cutter head, and a second pneumatic push rod;

[0010] The guide rails are symmetrically fixed at both ends of the top of the worktable, the moving table is slidably connected to the top of the guide rails, the chamfering motor is fixedly installed on the top of the moving table, the chamfering head is fixedly installed on the output end of the chamfering motor, and the second pneumatic push rod is fixedly installed on the top of the worktable and the output end of the second pneumatic push rod is fixedly connected to the moving table.

[0011] The moving platform, chamfering motor, and chamfering head are moved together by the second pneumatic push rod. The chamfering head is rotated by the chamfering motor. The two rotating chamfering heads move close to the ferrite core to achieve double-sided chamfering of the ferrite core.

[0012] As a further embodiment of this utility model: the feeding assembly includes an electric slide table, a third pneumatic push rod, a lifting platform, a parallel pneumatic gripper, an L-shaped moving arm, a linkage gear, a Z-shaped clamping arm, and an L-shaped toothed arm.

[0013] The electric slide is fixed to the top of the workbench by a bracket and distributed above the clamping assembly. The third pneumatic push rod is fixed to the top of the electric slide base, and the output end of the third pneumatic push rod passes through the bottom of the slide base and is fixedly connected to the lifting platform.

[0014] The parallel pneumatic gripper is fixed to the bottom of the lifting platform, the L-shaped moving arm is fixed to the two output ends of the parallel pneumatic gripper, the linkage gear is rotatably connected to one end of the lateral part of the L-shaped moving arm through a rotating shaft, and the Z-shaped clamping arm is fixedly connected to the rotating shaft.

[0015] The vertical part of the L-shaped toothed arm is fixed to the bottom of the parallel pneumatic gripper, and the bottom of the horizontal part of the L-shaped toothed arm is formed with tooth grooves and meshes with the linkage gear.

[0016] When the parallel pneumatic gripper drives the two L-shaped moving arms to approach each other, the two Z-shaped gripping arms rotate downwards synchronously to clamp the ferrite core.

[0017] When the parallel pneumatic gripper drives the two L-shaped moving arms to approach each other, the two Z-shaped gripping arms rotate synchronously upward to release the gripping of the ferrite core.

[0018] As a further improvement of this utility model: when the two L-shaped moving arms approach each other, the distance between the ends of the horizontal portions of the two L-shaped moving arms is greater than the width of the dust hood, and when the arms rotate downwards, the height of the vertical portion above is greater than the height of the dust hood.

[0020] As a further improvement of this utility model: the stroke length of the electric slide is greater than the width of the worktable, and the two sides of the electric slide protrude from the outer sides of the worktable.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By installing a dust suction hood on top of the movable clamping block, the dust suction hood is positioned close to the ferrite core, thus providing good coverage and shielding over the chamfered area, achieving efficient dust suction. In addition, by setting up a feeding assembly, the clamping structure composed of L-shaped toothed arms and Z-shaped clamping arms ensures that the area between the two sets of L-shaped toothed arms and Z-shaped clamping arms is larger than the outer wall size of the dust suction hood when clamping the ferrite core. This does not affect the movement of the movable clamping block and the dust suction hood, thus ensuring the smooth operation of the device. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figures 1-3In this embodiment of the utility model, a ferrite core chamfering device includes a worktable 1, a clamping assembly 2, a chamfering assembly 3, and a feeding assembly 4. The clamping assembly 2 includes a fixed clamping block 201, a first pneumatic push rod 202, and a movable clamping block 203.

[0029] The fixed clamping block 201 and the first pneumatic push rod 202 are respectively fixedly installed on the top two sides of the workbench 1. The movable clamping block 203 is fixed to the output end of the first pneumatic push rod 202. The movable clamping block 203 is driven to approach the fixed clamping block 201 by the first pneumatic push rod 202 to achieve the clamping and fixing of the ferrite core.

[0030] The top of the movable clamping block 203 is fixed with a dust suction hood 5, and the top of the dust suction hood 5 is fixed with a dust suction pipe 6 that is connected to an external suction device. When the ferrite core is beveled by the bevel assembly 3, the dust suction hood 5 is used to intercept the scattered dust, and the dust is collected by the operation of the external suction device.

[0031] The chamfering assembly 3 includes a guide rail 301, a moving table 302, a chamfering motor 303, a chamfering cutter head 304, and a second pneumatic push rod 305;

[0032] Guide rails 301 are symmetrically fixed at both ends of the top of the worktable 1. The moving table 302 is slidably connected to the top of the guide rails 301. The chamfering motor 303 is fixedly installed on the top of the moving table 302. The chamfering head 304 is fixedly installed at the output end of the chamfering motor 303. The second pneumatic push rod 305 is fixedly installed on the top of the worktable 1 and the output end of the second pneumatic push rod 305 is fixedly connected to the moving table 302.

[0033] The second pneumatic push rod 305 drives the moving table 302, the chamfering motor 303, and the chamfering cutter head 304 to move as a whole. The chamfering motor 303 drives the chamfering cutter head 304 to rotate. The two rotating chamfering cutter heads 304 move closer to the ferrite core to achieve double-sided chamfering of the ferrite core.

[0034] In this embodiment: the ferrite core can be transported to the inside of the fixed clamping block 201 by the feeding component 4, and then the first pneumatic push rod 202 is activated to drive the movable clamping block 203 to move closer to the fixed clamping block 201, so as to finally achieve the fixed clamping of the ferrite core. After that, the feeding component 4 releases the clamping of the ferrite core and moves upward away from the operating area of ​​the chamfering component 3.

[0035] Then, the two second pneumatic push rods 305 and the two chamfering motors 303 operate synchronously. The chamfering motors 303 drive the chamfering cutter head to rotate at high speed, and the second pneumatic push rods 305 bring the two chamfering cutter heads close to the ferrite core to achieve double-sided chamfering of the ferrite core.

[0036] During this process, the external suction device is activated simultaneously. The external suction device generates suction force, which is transmitted to the dust hood 5 to achieve the dust suction operation generated by the chamfer. The dust hood 5 is located on the top of the movable clamp 203 and is close to the ferrite core. Therefore, it can form a good coverage and shielding above the chamfer area, thereby achieving a high-efficiency dust suction effect.

[0037] Please refer to this carefully. Figures 1-3 The feeding assembly 4 includes an electric slide table 401, a third pneumatic push rod 402, a lifting table 403, a parallel pneumatic gripper 404, an L-shaped moving arm 405, a linkage gear 406, a Z-shaped clamping arm 407, and an L-shaped toothed arm 408.

[0038] The electric slide table 401 is fixed to the top of the worktable 1 by a bracket and distributed above the clamping assembly 2. The third pneumatic push rod 402 is fixed to the top of the slide of the electric slide table 401, and the output end of the third pneumatic push rod 402 passes through the bottom of the slide and is fixedly connected to the lifting platform 403.

[0039] Parallel pneumatic gripper 404 is fixed to the bottom of lifting platform 403, L-shaped moving arm 405 is fixed to the two output ends of parallel pneumatic gripper 404, linkage gear 406 is rotatably connected to one end of the horizontal part of L-shaped moving arm 405 through a rotating shaft, and Z-shaped clamping arm 407 is fixedly connected to the rotating shaft 306.

[0040] The vertical part of the L-shaped toothed arm 408 is fixed to the bottom of the parallel pneumatic gripper 404, and the bottom of the horizontal part of the L-shaped toothed arm 408 is formed with tooth grooves and meshes with the linkage gear 406.

[0041] When the parallel pneumatic gripper 404 drives the two L-shaped moving arms 405 to approach each other, the two Z-shaped gripping arms 407 rotate downwards synchronously to clamp the ferrite core.

[0042] When the parallel pneumatic gripper 404 drives the two L-shaped moving arms 405 to approach each other, the two Z-shaped gripping arms 407 rotate upward synchronously to release the gripping of the ferrite core.

[0043] When the two L-shaped moving arms 405 approach each other, the distance between the ends of the horizontal parts of the two L-shaped moving arms 405 is greater than the width of the dust hood 5, and when 407 rotates downward, the height of the vertical part above 407 is greater than the height of the dust hood 5.

[0044] The centerline of the Z-shaped clamping arm 407 is on the same horizontal plane as the center of the fixed clamping block 201 and the first pneumatic push rod 202.

[0045] In this embodiment: the horizontal movement of the parallel pneumatic gripper 404 can be realized by the electric slide table 401, and the vertical movement of the parallel pneumatic gripper 404 can be realized by the third pneumatic push rod 402;

[0046] The parallel pneumatic gripper 404 can drive the two L-shaped moving arms 405 to move closer or further away. When the two L-shaped moving arms 405 move closer, the linkage gear 406 rotates under the limiting action of the L-shaped gear arm 408, which can drive the Z-shaped clamping arm 407 to rotate from horizontal to vertical downward. At this time, the distance between the vertical parts below the two Z-shaped clamping arms 407 matches the ferrite core, thereby realizing the clamping of the ferrite core.

[0047] Similarly, when the two L-shaped moving arms 405 move away from each other, the Z-shaped clamping arm 407 rotates from vertical downward to horizontal rotation, thereby releasing the clamping of the ferrite core.

[0048] Through the cooperation of the above-mentioned components, the ferrite core can be picked up, loaded, and unloaded. When the clamping structure composed of the L-shaped toothed arm 408 and the Z-shaped clamping arm 407 clamps the ferrite core, the area between the two sets of L-shaped toothed arms 408 and Z-shaped clamping arms 407 is larger than the outer wall size of the dust hood 5. This will not affect the movement of the movable clamping block 203 and the dust hood 5, thus ensuring the smooth operation of the device.

[0049] Please refer to this carefully. Figures 1-3 The stroke length of the electric slide 401 is greater than the width of the worktable 1, and the two sides of the electric slide 401 protrude from the outer sides of the worktable 1.

[0050] In this embodiment, the parallel pneumatic gripper 404 can be moved to the outside area of ​​the worktable 1 by the electric slide 401 through this structure, which facilitates cooperation with the external feeding device and receiving device.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
