Description

Technical Field

[0001] The present invention relates to the technical field of magnetic material processing, and particularly relates to a drilling and grinding device for magnetic materials. Background Art

[0002] Materials that can respond to a magnetic field in a certain way are called magnetic materials. Generally, the magnetic materials mentioned refer to ferromagnetic substances. Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the ease of demagnetization after magnetization. As a kind of functional material, magnetic materials mainly utilize the magnetic properties and magnetic effects of the materials to realize functions such as conversion, transmission, modulation, storage, and detection of energy and information. Magnetic materials have important applications in traditional disciplines such as information storage, sensors, magnetic fluids, and radar stealth. In many applications, magnetic materials need to be assembled or used in specific shapes and sizes. Therefore, drilling operations need to be performed on them to provide installation, connection, or fixing points for these materials.

[0003] Deficiencies in the prior art: During the drilling process of magnetic materials by existing drilling devices, burrs and flash may be generated. Therefore, after drilling is completed, the magnetic materials need to be transferred to a grinding device for grinding operations. The existing drilling devices cannot achieve continuous operations of drilling and grinding magnetic materials, resulting in low working efficiency of the device. At the same time, after the magnetic materials are transferred to the working station, they need to be re-fixed, and deviations will occur between the grinding position and the drilling position, resulting in inaccurate grinding and affecting the surface quality of the magnetic materials. Summary of the Invention

[0004] The problem to be solved by the present invention is that the existing drilling devices cannot achieve continuous operations of drilling and grinding magnetic materials. At the same time, after the magnetic materials are transferred to the working station, they need to be re-fixed, which easily leads to inaccurate grinding positions and affects the surface quality of the magnetic materials.

[0005] To solve the above technical problems, the present invention provides a drilling and grinding device for magnetic materials, including an operating table and a support frame fixedly installed at one end thereof. A fixing component for fixing magnetic materials is provided at the top end of the operating table. A material discharging hole is opened in the middle of the top end of the operating table. A chute is opened in the middle of the support frame, and a drilling and grinding component for drilling and grinding magnetic materials is arranged in the inner cavity of the chute;

[0006] The drilling and grinding component includes an equipment frame movably connected to the inner cavity of the chute. A rotation turntable is arranged in the middle of the inner cavity of the equipment frame. A limiting plate is fixedly connected to one side of the bottom end of the rotation turntable, and a limiting hole is opened in the middle of the bottom end of the limiting plate.

[0007] Preferably, a rotation motor is fixedly installed at the top end of the inner wall of the equipment frame, and the output end of the rotation motor is fixedly connected to the middle of the top end of the rotation turntable.

[0008] Preferably, mounting brackets are fixedly connected to both sides of the top end of the transposition turntable. A drilling driving mechanism and a grinding driving mechanism are respectively arranged in the inner cavities of the two mounting brackets. The output end of the drilling driving mechanism penetrates through the transposition turntable and is fixedly connected with a drill bit, and the output end of the grinding driving mechanism penetrates through the transposition turntable and is fixedly connected with a grinding disc.

[0009] Preferably, the position of the drilling driving mechanism is symmetrically arranged with the position of the grinding driving mechanism. The position of the drill bit corresponds to the position of the limiting hole, and the position of the limiting hole corresponds to the position of the blanking hole.

[0010] Preferably, a protective cover is fixedly installed on one side of the bottom end of the transposition turntable, and the protective cover is sleeved on the outer surface of the drill bit.

[0011] Preferably, a lifting hydraulic cylinder is fixedly installed at the top end of the support frame, and the output end of the lifting hydraulic cylinder penetrates through the support frame and is fixedly connected with the top end of the equipment frame.

[0012] Preferably, the fixing assembly includes a fixing frame fixedly connected to one side of the top end of the operating table. An adjusting groove is opened at one end of the fixing frame away from the support frame. A bidirectional threaded rod is rotatably connected to the middle of the inner cavity of the fixing frame.

[0014] Preferably, a collection box is arranged at the bottom end of the operating table.

[0015] The technical effects and advantages of the present invention:

[0016] 1. The present invention performs continuous operations of drilling and grinding on magnetic materials through the provided drilling and grinding assembly. First, the drilling driving mechanism drives the drill bit to perform drilling operations on magnetic materials. After drilling is completed, the transposition motor is started, and the transposition turntable is rotated through the transposition motor to convert the grinding disc to the position of the drill bit. Then, the grinding driving mechanism is started to drive the grinding disc to perform grinding operations on the drilling position of the magnetic materials. It is not necessary to transfer the drilled magnetic materials to other devices to perform grinding treatment, enabling the device to perform continuous operations, avoiding re-fixing after the magnetic materials are transferred to different workstations, resulting in deviations between the grinding position and the drilling position, inaccurate grinding, and affecting the surface quality of the magnetic materials, effectively improving the working efficiency of the device.

[0017] 2. The present invention fixes the magnetic material through a fixed component. Place the magnetic material to be drilled and polished on the top of the operating table. Then, rotate the rotating rod to drive the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, the two thread blocks with opposite directions on its surface drive the two connecting blocks to move, so that the two connecting blocks can drive the two clamping plates to move equidistantly. When the bidirectional threaded rod rotates clockwise, the two clamping blocks move towards the middle, and when it rotates counterclockwise, they move towards both sides. The magnetic material is fixed at the middle position on the top of the operating table by the two clamping plates, ensuring the accuracy of the processing position of the magnetic material.

[0018] 3. The present invention limits the drilling position of the magnetic material through a limiting plate and a limiting hole. Before drilling the magnetic material, first, the extending end of the lifting hydraulic cylinder pushes the equipment rack downward, so that the limiting plate is fixed on the top of the magnetic material. At the same time, move the position to be drilled to the limiting hole. Then, fix the two ends of the magnetic material through the fixed component. When the drill bit performs the drilling operation, it can drill the specified position through the limiting hole, ensuring the accuracy of the drilling position of the magnetic material.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention provides a magnetic material drilling and grinding device, as Figure 1 - Figure 6 shown, which includes an operating table 1 and a support frame 2 fixedly installed at one end thereof. A fixing component 3 for fixing the magnetic material is provided at the top end of the operating table 1. A material discharging hole 4 is opened in the middle of the top end of the operating table 1. A sliding groove 5 is opened in the middle of the support frame 2. A drilling and grinding component 6 for drilling and grinding the magnetic material is arranged in the inner cavity of the sliding groove 5.

[0027] Further, as Figure 1 and Figure 2 shown, the drilling and grinding component 6 includes an equipment frame 61 movably connected to the inner cavity of the sliding groove 5. A position-changing turntable 62 is arranged in the middle of the inner cavity of the equipment frame 61. One side of the bottom end of the position-changing turntable 62 is fixedly connected with a limiting plate 63. A limiting hole 64 is opened in the middle of the bottom end of the limiting plate 63.

[0028] Further, as Figure 2 and Figure 3 shown, a position-changing motor 65 is fixedly installed at the top end inner wall of the equipment frame 61. The output end of the position-changing motor 65 is fixedly connected with the middle of the top end of the position-changing turntable 62. The position-changing turntable 62 is driven to rotate by the position-changing motor 65.

[0029] Further, as Figure 2 and Figure 3 shown, mounting frames 66 are fixedly connected to both sides of the top end of the position-changing turntable 62. A drilling driving mechanism 67 and a grinding driving mechanism 68 are respectively arranged in the inner cavities of the two mounting frames 66. The output end of the drilling driving mechanism 67 penetrates through the position-changing turntable 62 and is fixedly connected with a drill bit 69. The output end of the grinding driving mechanism 68 penetrates through the position-changing turntable 62 and is fixedly connected with a grinding disc 610. The drill bit 69 is driven by the drilling driving mechanism 67 to perform a drilling operation on the magnetic material. The grinding disc 610 is driven by the grinding driving mechanism 68 to perform a grinding operation on the magnetic material.

[0030] Further, as Figure 2 and Figure 3 shown, the position of the drilling driving mechanism 67 and the position of the grinding driving mechanism 68 are symmetrically arranged, ensuring that the positions after conversion between the drill bit 69 and the grinding disc 610 are consistent. The position of the drill bit 69 corresponds to the position of the limiting hole 64. The position of the limiting hole 64 corresponds to the position of the material discharging hole 4. Before drilling the magnetic material, first fix its top position through the limiting plate 63, and at the same time move the position to be drilled to the limiting hole 64. Then fix both ends of the magnetic material through the fixing component 3, so that the drill bit 69 drills at the specified position through the limiting hole 64, ensuring the accuracy of the drilling position of the magnetic material. The residues and debris generated during drilling fall through the material discharging hole 4.

[0031] Furthermore, as Figure 2 and Figure 3 shown, a protective cover 611 is fixedly installed on one side of the bottom end of the transposition turntable 62. The protective cover 611 is sleeved on the outer surface of the drill bit 69, and the protective cover 611 plays a protective role for the drill bit 69.

[0032] Furthermore, as Figure 3 and Figure 4 shown, a lifting hydraulic cylinder 7 is fixedly installed at the top end of the support frame 2. The output end of the lifting hydraulic cylinder 7 penetrates through the support frame 2 and is fixedly connected to the top end of the equipment frame 61. Before operation, first start the lifting hydraulic cylinder 7. The extending end of the lifting hydraulic cylinder 7 pushes the equipment frame 61 to move up and down in the inner cavity of the chute 5. The drilling position at the top end of the magnetic material is limited by the limiting plate 63 and the limiting hole 64. Then start the drilling driving mechanism 67 to drive the drill bit 69 to penetrate through the limiting hole 64 to drill the magnetic material. After drilling is completed, start the transposition motor 65. The transposition turntable 62 is rotated 180 degrees by the transposition motor 65 to convert the grinding disc 610 to the position of the drill bit 69. Then start the grinding driving mechanism 68 to drive the grinding disc 610 to perform grinding operation on the drilling position at the top end of the magnetic material. It is not necessary to transfer the drilled magnetic material to other devices to perform grinding treatment, so that the device can perform continuous operation, avoiding deviation between the grinding position and the drilling position caused by re-fixing after the magnetic material is transferred to the working station, resulting in inaccurate grinding and affecting the surface quality of the magnetic material, effectively improving the working efficiency of the device.

[0033] Furthermore, as Figure 5 and Figure 6 shown, the fixing assembly 3 includes a fixing frame 31 fixedly connected to one side of the top end of the operation table 1. An adjusting groove 32 is opened at one end of the fixing frame 31 away from the support frame 2. A bidirectional threaded rod 33 is rotatably connected to the middle of the inner cavity of the fixing frame 31. Two connecting blocks 34 are threadedly connected to the outer surface of the bidirectional threaded rod 33. A clamping plate 35 is fixedly connected to one end of each of the two connecting blocks 34 close to the adjusting groove 32. A rotating rod 36 is arranged at one end of the fixing frame 31. A fastening piece 37 is threadedly connected to the outer surface of the rotating rod 36. Before performing the drilling and grinding operations, first fix the magnetic material on the top end of the operation table 1 by the two clamping plates 35.

[0034] Furthermore, as Figure 5 and Figure 6As shown, the directions of the two threaded blocks formed on the surface of the bidirectional threaded rod 33 are opposite. One end of the rotating rod 36 penetrates through the fixing bracket 31 and is fixedly connected to one end of the bidirectional threaded rod 33. During fixation, the bidirectional threaded rod 33 is rotated by rotating the rotating rod 36. Since the directions of the two threaded blocks formed on the surface of the bidirectional threaded rod 33 are opposite, the two connecting blocks 34 threadedly connected to its surface can be driven to move equidistantly, ensuring that the magnetic material can be fixed at the middle position of the top end of the operating table 1 and ensuring the accuracy of the processing position of the magnetic material. After the magnetic material is fixed, the positions of the rotating rod 36 and the bidirectional threaded rod 33 are fastened by the fastener 37.

[0035] Further, as Figure 1 shown, a collection box 8 is provided at the bottom end of the operating table 1. During the operation, debris and residues generated during the process fall into the collection box 8 through the material discharge hole 4 for centralized treatment.

[0036] Working principle of the present invention: First, place the magnetic material on the top of the operating table 1, and start the lifting hydraulic cylinder 7. When the extending end of the lifting hydraulic cylinder 7 extends to the longest, it pushes the equipment frame 61 downward, so that the limiting plate 63 is fixed on the top of the magnetic material. Then, adjust the magnetic material according to the position where drilling is required, and adjust the position where drilling is required to the position of the limiting hole 64. After the adjustment is completed, rotate the rotating rod 36 clockwise to drive the bidirectional threaded rod 33 to rotate. Since the directions of the two threaded blocks provided on the surface of the bidirectional threaded rod 33 are opposite, the two connecting blocks 34 threadedly connected to its surface move equidistantly towards the middle, ensuring that the magnetic material can be fixed at the middle position on the top of the operating table 1, ensuring the accuracy of the processing position of the magnetic material. After the drilling and grinding operations are completed, rotate the rotating rod 36 counterclockwise, and the two clamping plates 35 move towards both sides. After the fixation is completed, fasten the positions of the rotating rod 36 and the bidirectional threaded rod 33 by rotating the fastener 37. Then, first start the drilling drive mechanism 67, and drive the drill bit 69 to penetrate through the limiting hole 64 through the drilling drive mechanism 67 to perform drilling operations on the top of the magnetic material. Ensure the accuracy of the drilling position of the drill bit 69 through the limiting hole 64. After the drilling is completed, start the transposition motor 65, and rotate the transposition turntable 62 by 180 degrees through the transposition motor 65 to convert the grinding disc 610 to the position of the drill bit 69. After the conversion is completed, start the grinding drive mechanism 68. Since burrs and flash will be generated during the drilling process of the magnetic material, drive the grinding disc 610 to perform grinding operations on the drilling position at the top of the magnetic material through the grinding drive mechanism 68 to ensure the surface quality of the magnetic material. It is not necessary to transfer the drilled magnetic material to other devices for grinding treatment, enabling the device to achieve continuous drilling and grinding operations, avoiding deviation between the grinding position and the drilling position caused by re-fixation after the magnetic material is transferred to a different station, resulting in inaccurate grinding and affecting the surface quality of the magnetic material, effectively improving the working efficiency of the device. After the drilling and grinding operations are completed, start the lifting hydraulic cylinder 7, so that the extending end of the lifting hydraulic cylinder 7 contracts to the shortest, driving the drilling and grinding assembly 6 back to the initial position. The residues and debris generated during the drilling process fall downward through the material discharge hole 4 into the collection box 8 for centralized treatment.
