Description

Technical Field

[0001] This application relates to the field of machining fixtures, and more particularly to a magnetic material machining fixture. Background Technology

[0002] Magnetic materials, also known as magnetic materials, refer to materials that can respond to magnetic fields in a certain way. Currently, most semi-finished magnetic materials are conical in shape, and conical magnetic materials include a large-diameter end face and a small-diameter end face.

[0003] During the forming process of tapered magnetic materials, both ends of the tapered magnetic material need to be ground flat. This grinding process requires a grinding device, which includes equipment for grinding the tapered magnetic material.

[0004] The process involves a grinding plate and a holding platform for grinding the top of the magnetic material. The holding platform has an arrangement slot for arranging the magnetic material, and a rotating disk for placing the magnetic material is positioned on the bottom of the arrangement slot. During grinding, the grinding plate revolves around the central axis to grind the top of the magnetic material, while the rotating disk rotates on its own axis and grinds the bottom of the magnetic material through its grinding surface. However, during this process, the magnetic material is prone to tilting, resulting in a tilted end face after grinding, leading to lower processing accuracy.

[0005] Regarding the aforementioned technologies, the inventors believe that a magnetic material processing fixture is needed to fix the processed magnetic material and improve the processing accuracy of tapered magnetic materials. Utility Model Content

[0006] To improve the machining accuracy of tapered magnetic materials, this application provides a magnetic material machining fixture.

[0007] The magnetic material processing fixture provided in this application adopts the following technical solution:

[0008] A magnetic material processing fixture includes a clamping plate and an abutment plate; the clamping plate has a first side and a second side arranged opposite to each other, and the clamping plate also has a tapered groove that passes through the first side and the second side and is used for arranging tapered magnetic materials; the inner diameter of the tapered groove gradually increases along the direction from the first side to the second side; the abutment plate is located on one side of the second side of the clamping plate and is used to press the large-diameter end face of the tapered magnetic material.

[0009] By adopting the above technical solution, in the process of processing the conical magnetic material, the large-diameter end face of the conical magnetic material is first arranged in the conical groove of the clamping plate with the large-diameter end face facing upward, thereby reducing the probability of the conical magnetic material tilting during processing; after the large-diameter end face of the conical magnetic material is processed, the large-diameter end face of the conical magnetic material is pressed with the abutment plate, and then the clamping plate and the abutment plate are flipped. The abutment plate restricts the conical magnetic material from coming off the clamping plate during the flipping process. In the above processing process, the setting of the clamping plate and the abutment plate effectively improves the processing accuracy of the conical magnetic material.

[0010] Optionally, the abutment plate has a vertically extending insertion protrusion toward the clamping plate, and the clamping plate has an insertion groove for inserting the insertion protrusion; the outer wall of the insertion protrusion is horizontally provided with an installation groove and an elastic locking component is arranged in the installation groove; the clamping plate is provided with a locking groove on the inner wall of the insertion groove for engaging with the elastic locking component; when the elastic locking component and the locking groove engage, the abutment plate abuts against the large-diameter end face of the tapered magnet installed on the clamping plate.

[0011] By adopting the above technical solution, the locking mechanism in the insert protrusion and the locking groove in the insert groove are engaged to achieve a locking fit between the clamping plate and the abutment plate. The abutment plate is then pressed against the large-diameter end face of the tapered magnetic material installed on the clamping plate, thereby preventing the tapered magnetic material from coming out of the tapered groove of the clamping plate.

[0012] Optionally, the elastic locking assembly includes a locking housing inserted into the mounting groove, a locking protrusion slidably arranged within the locking housing, and a locking spring installed within the locking housing; the locking protrusion has a limiting plate and a locking portion for cooperating with the locking groove; the locking housing has a locking opening for allowing the locking portion to extend and restricting the limiting plate from disengaging; one end of the locking spring abuts against the limiting plate and the other end abuts against the inner cavity sidewall of the locking housing and drives the locking portion to always tend to move away from the locking housing.

[0013] By adopting the above technical solution, the structure of the elastic locking assembly is disclosed. A locking spring drives the locking protrusion to always slide away from the locking housing. When the locking protrusion encounters the locking groove, the locking part of the locking protrusion automatically extends into the locking groove, thereby achieving a locking engagement between the clamping plate and the abutment plate. The locking opening helps to prevent the limiting plate from protruding from the locking housing.

[0014] Optionally, the locking groove is a through groove extending to the outer wall of the clamping plate; the locking groove is provided with an unlocking mechanism for unlocking the elastic locking component; the locking groove includes a first groove and a second groove in sequence along the direction away from the insertion groove, and the diameter of the first groove is larger than the diameter of the second groove; the unlocking mechanism includes an unlocking member slidably arranged in the locking groove, an unlocking spring sleeved on the unlocking member, and an unlocking nut installed on the unlocking member; the unlocking member includes an unlocking disc slidably arranged in the first groove and an unlocking post extending through the second groove to the outside of the clamping plate; one end of the unlocking spring abuts against the unlocking nut and the other end abuts against the clamping plate.

[0015] By adopting the above technical solution, the structure of the unlocking mechanism is disclosed. When it is necessary to unlock the elastic locking component, the operator pushes the unlocking pin towards the insertion protrusion, causing the locking disc to abut against the end face of the insertion protrusion. This causes the locking part of the locking protrusion to disengage from the locking groove, achieving rapid separation of the clamping plate and the abutment plate. The unlocking spring facilitates the automatic reset of the unlocking pin.

[0016] Optionally, the clamping plate has an arrangement slot for arranging the unlocking spring and the unlocking nut.

[0017] By adopting the above technical solution, the arrangement of the slots makes the structure of the unlocking mechanism more compact, ensuring that the unlocking mechanism can properly cooperate with the elastic locking component and enable the quick installation and removal of the clamping plate and the abutment plate.

[0018] Optionally, the end of the unlocking post away from the unlocking disc is provided with anti-slip texture.

[0019] By adopting the above technical solution, the anti-slip texture helps to increase the friction between the finger and the unlocking post, thereby facilitating the pushing of the unlocking post toward the insertion protrusion post, and realizing the unlocking between the clamping plate and the abutment plate.

[0020] Optionally, the top of the insertion slot is provided with an elastic element for the insertion protrusion to abut against, and the elastic element drives the insertion protrusion to always have a tendency to disengage from the insertion slot.

[0021] By adopting the above technical solution, an elastic element is set at the top of the insertion slot, and the top surface of the insertion protrusion abuts against the elastic element, so that the insertion protrusion always has a tendency to disengage from the insertion slot, which helps the operator to separate the clamping plate from the abutment plate.

[0022] Optionally, the abutment plate has an annular limiting protrusion on its surface facing the clamping plate to restrict the conical magnet.

[0023] By adopting the above technical solution, the setting of the annular limiting protrusion helps to limit the conical magnetic material and reduce the probability of the conical magnetic material being displaced.

[0024] Optionally, the clamping plate has a handle arrangement groove in the middle of the first side and a lifting handle is provided in the handle arrangement groove.

[0025] By adopting the above technical solution, the handle arrangement slot helps reduce the probability of the lifting handle interfering with the grinding process of the conical magnetic material, thus ensuring the processing accuracy of the conical magnetic material. The lifting handle also helps the operator lift the clamping plate, achieving separation between the clamping plate and the abutment plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. A magnetic material processing fixture, wherein the conical groove in the clamping plate helps to provide support for the conical magnetic material, reducing the probability of the conical magnetic material tilting during processing, and the abutment plate presses the conical magnetic material into the conical groove, thereby flipping the clamping plate on which the conical magnetic material is installed, reducing the probability of the conical magnetic material coming out of the conical groove during the flipping process. Through the cooperation of the clamping plate and the abutment plate, the processing accuracy of the conical magnetic material is effectively improved during processing.

[0028] 2. By setting up elastic locking components and unlocking mechanisms, the clamping plate and the abutment plate can be quickly disassembled and installed, improving the flexibility and adjustability of the magnetic material processing fixture;

[0029] 3. By setting an elastic element at the top of the insertion slot, the insertion protrusion always tends to disengage from the insertion slot, which helps to separate the clamping plate from the abutment plate. Attached Figure Description

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] This application discloses a magnetic material processing fixture. (Refer to...) Figure 1 The conical magnetic material 1 is frustum-shaped, and has a large-diameter end face 11 and a small-diameter end face 12. Therefore, subsequent conical magnetic materials 1 and their related characteristics can be directly referenced. Figure 1 The attached figures will not be cited separately.

[0037] Reference Figure 2 A magnetic material processing fixture includes a clamping plate 2 and an abutment plate 3, both of which are rectangular parallelepiped plates. The clamping plate 2 has a first side 21 and a second side 22 arranged opposite to each other, and the clamping plate 2 has a tapered groove 23 extending through the first side 21 and the second side 22 for accommodating a tapered magnetic material 1. The inner diameter of the tapered groove 23 gradually increases along the direction from the first side 21 to the second side 22.

[0038] Reference Figure 2 and Figure 3The abutment plate 3 assists the clamping plate 2 in pressing the conical magnet 1 into the clamping plate 2. The abutment plate 3 abuts against the large-diameter end face 11 of the conical magnet 1. The abutment plate 3 also has an annular limiting protrusion 31 on the surface facing the clamping plate 2 to limit the displacement of the conical magnet 1. The inner diameter of the annular limiting protrusion 31 is adapted to the outer diameter of the large-diameter end face 11 of the conical magnet 1. The abutment plate 3 is located on one side of the second side 22 of the clamping plate 2 and is inserted into the clamping plate 2. The side of the abutment plate 3 facing the clamping plate 2 has an insertion protrusion 32 that extends vertically toward the clamping plate 2. The insertion protrusion 32 is a protrusion with a rectangular cross-section. The clamping plate 2 has an insertion groove 24 for inserting the insertion protrusion 32. The cross-section of the insertion groove 24 matches the cross-section of the insertion protrusion 32. The top of the insertion slot 24 is provided with an elastic element 25 for the top surface of the insertion protrusion 32 to abut against. The elastic element 25 is a drive spring. The drive spring makes the insertion protrusion 32 always tend to disengage from the insertion slot 24.

[0039] Reference Figure 2 and Figure 3 To achieve rapid locking between the clamping plate 2 and the abutment plate 3, the outer wall of the insertion protrusion 32 is provided with a horizontal mounting groove 321, and an elastic locking element is arranged in the mounting groove 321. The clamping plate 2 is provided with a locking groove 26 on the inner wall of the insertion groove 24 for the elastic locking assembly to cooperate with. The locking groove 26 is a through groove extending to the outer wall of the clamping plate 2. When the elastic locking assembly and the locking groove 26 are engaged, the abutment plate 3 abuts against the large-diameter end face 11 of the tapered magnet 1 installed on the clamping plate 2. The elastic locking assembly includes a locking housing 41 inserted into the mounting groove 321, a locking protrusion 42 slidably arranged in the locking housing 41, and a locking spring 43 installed in the locking housing 41. The locking protrusion 42 has a limiting plate 421 and a locking part 422 connected to the end of the limiting plate 421 facing the locking groove 26 and used to cooperate with the locking groove 26. The end of the locking part 422 away from the limiting plate 421 also has a chamfered structure. The locking housing 41 has a locking opening 411 on the side facing the locking groove 26 for the locking part 422 to extend out and for preventing the limiting plate 421 from disengaging from the locking housing 41. One end of the locking spring 43 abuts against the limiting plate 421 and the other end abuts against the inner cavity sidewall of the locking housing 41. The locking spring 43 is provided such that the locking part 422 of the locking protrusion 42 always has a tendency to slide away from the locking housing 41.

[0040] Reference Figure 2 and Figure 3To enable rapid unlocking of the clamping plate 2 and the abutment plate 3, an unlocking mechanism for unlocking the elastic locking assembly is provided in the locking groove 26. The unlocking mechanism includes an unlocking member 51 slidably arranged within the locking groove 26, an unlocking spring 52 sleeved on the unlocking member 51, and an unlocking nut 53 threaded onto the unlocking member 51. The locking groove 26, along the direction away from the insertion groove 24, sequentially includes a first groove 261 and a second groove 262. The diameter of the first groove 261 is larger than the diameter of the second groove 262, and the first groove 261 has an abutment surface 2611 for the unlocking member 51 to abut against. The unlocking member 51 includes an unlocking disc 511 slidably arranged within the first groove 261 and an unlocking post 512 connected to the unlocking disc 511 on the side facing the outer wall of the clamping plate 2. The unlocking post 512 extends through the second groove 262 to the outside of the clamping plate 2. One end of the unlocking spring 52 abuts against the unlocking nut 53 and the other end abuts against the clamping plate 2, enabling the unlocking pin 512 to automatically reset. The clamping plate 2 has an arrangement groove 263 for arranging the unlocking spring 52 and the unlocking nut 53. After being pushed by the operator, the unlocking pin 512 has a first position and a second position. When the unlocking pin 512 is in the first position, the unlocking disc 511 is located in the first groove 261 and the locking part 422 of the locking protrusion 42 cooperates with the locking groove 26, and the clamping plate 2 and the abutment plate 3 are in a locked state. When the unlocking pin 512 is in the second position, the unlocking disc 511 abuts against the insertion protrusion 32, realizing the unlocking between the clamping plate 2 and the abutment plate 3, thereby separating the clamping plate 2 and the abutment plate 3. The end of the unlocking pin 512 away from the unlocking disc 511 is also provided with anti-slip texture 5121, which helps the operator to push the unlocking disc 511.

[0041] Reference Figure 2 and Figure 4 In order to facilitate the lifting of the clamping plate 2 and separation from the abutment plate 3, the clamping plate 2 has a handle arrangement groove 27 in the middle of the first side 21, and a lifting handle 28 is provided in the handle arrangement groove 27.

[0042] The implementation principle of a magnetic material processing fixture in this application embodiment is as follows: During the grinding process of the conical magnetic material 1, the conical magnetic material 1 is first placed in the conical groove 23 of the clamping plate 2, and the large diameter end face 11 of the conical magnetic material 1 is ground. After the large diameter end face 11 of the conical magnetic material 1 is ground, the elastic locking component in the insert protrusion 32 on the limiting plate and the locking groove 26 at the insertion groove 24 of the clamping plate 2 are engaged to achieve locking between the clamping plate 2 and the abutment plate 3. Then, the abutment plate 3 and the conical magnetic material are arranged... The clamping plate 2 of material 1 is flipped over, and the small diameter end face 12 of the tapered magnetic material 1 is polished. After polishing, the unlocking post 512 is pushed to slide towards the insertion protrusion 32 until the locking post abuts against the locking housing 41. Then, the insertion protrusion 32 is driven by the elastic element 25 at the top of the insertion groove 24 to achieve separation between the clamping plate 2 and the abutting plate 3. Through the cooperation between the clamping plate 2 and the abutting plate 3, the probability of the tapered magnetic material 1 tilting during processing is reduced, and the processing accuracy of the tapered magnetic material 1 is effectively improved.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
