Description

Technical Field

[0001] This utility model relates to the field of chip cutting technology, specifically a workpiece fixing mechanism for a nanocrystalline magnetic core cutting machine. Background Technology

[0002] The nanocrystalline magnetic core cutting machine is an advanced piece of equipment specifically designed for high-precision cutting of nanocrystalline magnetic cores and other magnetic materials. It employs leading cutting technology and a precision guide rail system to ensure exceptional cutting accuracy. The machine frame undergoes special treatments, such as gantry milling and stress-relief processes, to guarantee long-term stability.

[0003] During the cutting process of the nanocrystalline magnetic core cutting machine, the chip workpiece needs to be kept fixed during the cutting process. In the current structure, the chip will be laid flat on the cutting table, which makes it inconvenient to remove the chip from the cutting table after cutting, making the chip unloading very inconvenient.

[0004] For example, the chip board cutting device for chip production disclosed in Chinese Patent Publication No. CN221984178U can raise the unloading rod by activating the lifting device, which can push the cut chip board out of the placement slot, making the unloading of the cut chip very convenient. The limiting component can make the fixed seat more stable on the processing table and make the fixed seat easy to replace, thus facilitating the cutting of chips of different sizes.

[0005] The limiting component in the aforementioned device moves the clamping block by rotating the first screw, thereby abutting the chip in the placement slot. However, this abutting method can cause the chip to bend, be damaged, or even break if the first screw rotates excessively. Therefore, this rigid abutting method needs further improvement because the abutting force cannot be determined during the chip fixing process. Furthermore, this abutting method can only fix a single chip, and its compatibility and practicality also urgently need improvement. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a workpiece fixing mechanism for a nanocrystalline magnetic core cutting machine, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a workpiece fixing mechanism for a nanocrystalline magnetic core cutting machine, comprising a clamping base, on which fixing mechanisms are symmetrically arranged on both sides, and a slot is formed in the middle of the clamping base between the fixing mechanisms. Each fixing mechanism includes a clamping unit for fixing the chip workpiece and a linkage unit for cutting rotation. The clamping unit is mounted on the clamping base, and the linkage unit is mounted on the clamping unit. The clamping unit includes arc-shaped seats symmetrically arranged on the top of the clamping base, with clamping molds distributed on the side of the arc-shaped seats near the slot. A placement plate is installed between the clamping molds, and a transmission air pipe is fixedly connected to one side of the arc-shaped seat. An air pump is installed on the transmission air pipe, and the two transmission air pipes are connected to each other. A wire is connected to the other side of the arc-shaped seat, and a switch is connected to the wire. Furthermore, this application adopts two technical solutions to address the direct contact of existing technologies. Facing the complex and ever-changing chip cutting environment, the start of the air pump creates negative pressure in the transmission air pipe, which adsorbs and fixes the placement plate, thereby avoiding direct contact. The rigid fixation is changed to soft negative pressure adsorption, preventing the chip from bending or breaking.

[0008] A further improvement of the present invention is that: the placement plate is fixed in the clamping mold by the air pressure transmitted through the transmission air pipe, the placement plate is arranged in an array of placement slots, each placement slot has a corresponding suction nozzle fixedly installed at the bottom, and the other end of each suction nozzle is connected to a hose, the other end of the hose passes through the placement plate and is installed in the middle of the transmission air pipe.

[0009] It should be noted that this application addresses the cutting operation of batch chips, therefore it sets up a placement groove for placing multiple chips, and utilizes the technical features disclosed above to link the suction nozzle embedded in the placement groove, thereby completing the adsorption and fixation of multiple chips in one operation through negative pressure, thus improving the practicality of this application.

[0010] A further improvement of this utility model's technical solution lies in that the clamping mold further includes either of the following two configurations:

[0011] The clamping mold is an electromagnet, and the outer surface of the clamping mold fits the outer surface of the chip to be fixed. It should be noted that when the clamping mold is used for high-precision cutting of a single chip, it is necessary to ensure that the chip is made of metal and has magnetic properties.

[0012] The clamping mold has a slot in the middle for holding the placement plate.

[0013] A further improvement of this utility model is that, in order for the fixed chip to move to a certain extent during the cutting process, a moving groove is provided on the arc-shaped base, and a moving block is provided in the moving groove. The moving block is slidably installed in the arc-shaped base through the moving groove, and the moving block is fixedly connected to the arc-shaped base by fasteners. It should be noted that the moving block in this application can be limited and fixed by fasteners during the cutting process, thereby avoiding sudden displacement during cutting. This is quite common in the technical field, so it will not be described in detail here.

[0014] A further improvement of this utility model is that, in order to ensure that the chip can adaptively rotate to a certain extent during chip cutting, this application proposes the following technical solution: the linkage unit includes a support rod fixedly connected to the arc-shaped base, the support rod being rotatably mounted on a fixed block, and a drive shaft connected to a drive motor being rotatably mounted on the other side of the support rod. A linkage sleeve is keyed to the drive shaft, and linkage rods are fixed on the linkage sleeve array. During the rotation of the drive shaft, the connected support rod and the fixed arc-shaped base rotate, achieving rotation after the chip is fixed, thus avoiding cutting dead angles. While ensuring stable fixation, the slots opened in the clamping base avoid motion interference that may occur when the arc-shaped base rotates.

[0015] A further improvement of this utility model is that: the other end of the linkage rod is fixedly connected to a rotating block, and the rotating block is slidably installed in a circular track.

[0016] A further improvement of this utility model is that a horizontal partition plate is fixed between the two circumferential tracks, and the horizontal partition plate is fixedly connected to the clamping base.

[0017] Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are: by using the air pump and suction nozzle in the clamping unit to fix the chip, direct contact between the clamping block and the chip is avoided, thus avoiding chip breakage caused by rigid compression. Furthermore, by embedding multiple sets of suction nozzles in the placement groove, multiple sets of chips can be fixed at the same time, improving the practicality of this application, changing the contact method, and selectively using magnetic adsorption to achieve precision cutting of a single chip.

[0019] Through the coordinated operation of the clamping unit and the linkage unit, the chip that is adsorbed and fixed rotates under the rotation of the drive shaft, avoiding cutting dead angles, and the slight throwing generated by the rotation does not cause too much resistance to the air pressure adsorption, ensuring the proper fixation of the chip.

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] This utility model provides a workpiece fixing mechanism for a nanocrystalline magnetic core cutting machine, including a clamping base 1. Fixing mechanisms are symmetrically arranged on both sides of the clamping base 1, and a slot 2 is opened in the middle of the clamping base 1 between the fixing mechanisms. The fixing mechanism includes a clamping unit for fixing the chip workpiece and a linkage unit for cutting and rotating. The clamping unit is installed on the clamping base 1, and the linkage unit is installed on the clamping unit.

[0029] The clamping unit includes an arc-shaped seat 3 symmetrically arranged on the top of the clamping base 1. Clamping molds 4 are distributed on the side of the arc-shaped seat 3 near the empty slot 2. A placement plate 5 is installed between the two clamping molds 4. A transmission air pipe 6 is fixedly connected to one side of the arc-shaped seat 3. An air pump 7 is installed on the transmission air pipe 6. The two transmission air pipes 6 are connected to each other. A wire 8 is connected to the other side of the arc-shaped seat 3. A switch 9 is connected to the wire 8.

[0030] Furthermore, this application addresses the direct contact issue in existing technologies by employing two technical solutions to address the complex and ever-changing chip cutting environment. The activation of the air pump 7 creates negative pressure in the transmission air pipe 6, which adsorbs and fixes the placement plate 5, thereby avoiding direct contact. The rigid fixation is replaced with soft negative pressure adsorption, preventing the chip from bending or breaking.

[0031] The placement plate 5 is fixed in the clamping mold 4 by the air pressure transmitted through the air transmission pipe 6. Placement slots are arranged in an array on the placement plate 5. A suction nozzle 10 is fixedly installed at the bottom of each placement slot. The other end of each suction nozzle 10 is connected to a hose 11. The other end of the hose 11 passes through the placement plate 5 and is installed in the middle of the air transmission pipe 6.

[0032] It should be noted that this application addresses the cutting operation of batch chips, therefore a placement groove is set up for placing multiple chips, and by utilizing the technical features disclosed above, the suction nozzle 10 embedded in the placement groove is linked, and multiple chips are adsorbed and fixed by a single operation of negative pressure, thereby improving the practicality of this application.

[0033] The clamping mold 4 also includes either of the following two settings:

[0034] The clamping mold 4 is an electromagnet, and the outer surface of the clamping mold 4 fits with the outer surface of the chip to be fixed.

[0035] It should be noted that when the clamping mold 4 is used for high-precision cutting of a single chip, it is important to ensure that the chip is made of metal and has magnetic properties.

[0036] The clamping mold 4 has a groove in the middle for engaging the placement plate 5.

[0037] In order for the fixed chip to move to a certain extent during the cutting process, a moving groove is provided on the arc surface seat 3, and a moving block 12 is provided in the moving groove. The moving block 12 is slidably installed in the arc surface seat 3 through the moving groove, and the moving block 12 is fixedly connected to the arc surface seat 3 by fasteners.

[0038] It should be noted that the movable block 12 in this application can be fixed by fasteners during the cutting process to avoid sudden displacement during cutting. This is common in the field of technology and will not be described in detail here.

[0039] In order to ensure that the chip can rotate to a certain extent adaptively during chip cutting, this application proposes the following technical solution: the linkage unit includes a support rod 13 fixedly connected to the arc surface seat 3, the support rod 13 is rotatably mounted on a fixed block 14, and a drive shaft 15 connected to a drive motor is rotatably mounted on the other side of the support rod 13. A linkage sleeve 16 is keyed to the drive shaft 15, and linkage rods 17 fixed thereon are arranged in an array on the linkage sleeve 16.

[0040] During the rotation of the drive shaft 15, the connected support rod 13 and its fixed arc seat 3 are rotated. The rotation is achieved after the chip is fixed, avoiding the occurrence of cutting dead angles. While ensuring stable fixation, the slot 2 opened in the clamping base 1 avoids motion interference that may occur when the arc seat 3 rotates.

[0041] The other end of the linkage rod 17 is fixedly connected to the rotating block 18, and the rotating block 18 is slidably installed in a circular track 19.

[0042] A horizontal partition 20 is fixed between the two circular tracks 19, and the horizontal partition 20 is fixedly connected to the clamping base 1.

[0043] In practical applications, when chips are cut in large quantities, this application selects a clamping mold 4 with a central slot and attaches it to a placement plate 5. The placement plate 5 is then laid flat via a linkage unit, and the chips are placed one by one into the placement slot. At this time, the air pump 7 is activated, and the air pressure is transmitted through the air pipe 6 to adsorb and fix the clamping mold 4 in the slot. The chips in the placement slot are also adsorbed and fixed by the suction nozzles 10 embedded in it, realizing the fixation of multiple materials. When performing precision cutting of a single chip, a clamping mold 4 that fits the outer wall of the chip model is selected. The clamping molds 4 on both sides are then wrapped around the chip. The external excitation device connected to the wire 8 is activated. After the wire 8 is energized, the switch 9 is activated. Since the clamping mold 4 is an electromagnet, it adsorbs the chip, thereby completing the fixation.
