[0022] Beneficial effects:
[0023] The fixing fixture provided by this invention first places the core in the fixing groove of the fixing block before core processing.

[0051] Reference Figures 1 to 6 As shown, this embodiment provides a fixing fixture for fixing the core 10. The fixing fixture includes a fixing block 100 and a movable module 200.
[0052] Specifically, the fixing block 100 includes a fixing surface 110, and a plurality of fixing grooves 111 are provided on the fixing surface 110 along the first direction. The fixing grooves 111 are used to place the core 10 extending along the second direction.
[0053] Specifically, the movable module 200 includes a movable block 210, a plurality of positioning members 220 slidably connected to the movable block 210, and a first elastic member 230 connected to the positioning members 220. Each fixing groove 111 is correspondingly provided with at least one positioning member 220. The movable block 210 is used to drive the positioning member 220 to move toward the fixing block 100 in a third direction to press against the core 10 in the fixing groove 111. The first elastic member 230 is configured to provide a force for the positioning member 220 to move toward the fixing block 100. Specifically, the first elastic member 230 may include, but is not limited to, a spring. Figure 1 In the diagram, direction a is the first direction, direction b is the second direction, and direction c is the third direction.
[0054] In this embodiment, before processing the core 10, the core 10 is first placed in the fixing groove 111 of the fixing block 100. Then, the movable block 210 is moved towards the fixing block 100 in a third direction, so that the positioning member 220 presses against the core 10, thereby fixing the core 10. This operation is convenient, time-saving, and labor-saving, achieving the purpose of clamping multiple cores 10 simultaneously, enabling batch processing, effectively improving the fixing efficiency of the core 10, and increasing the production efficiency of the core 10. In addition, the design of the first elastic member 230 provides a buffer for clamping the core 10, effectively preventing the positioning member 220 from excessively pressing against the core 10 and causing damage to the surface of the core 10. Moreover, the first elastic member 230 and the positioning member 220 correspond one-to-one, effectively ensuring that each core 10 is stably clamped and fixed. The fixing fixture is suitable for clamping and fixing cores 10 with an outer diameter of 1mm-8mm, and cores 10 with a diameter difference of 1mm can be clamped in the fixing groove 111 on the same fixing surface 110. Of course, by changing the size of the fixing groove 111 on the fixing member, the fixing fixture can be adapted to clamp and fix cores 10 of other diameters.
[0055] In one feasible implementation, such as Figure 1As shown, the fixing block 100 has fixing surfaces 110 on both sides along the third direction. The fixing clamp has two movable modules 200, each corresponding to a fixing surface 110. Each fixing surface 110 has multiple fixing slots 111 along the first direction, allowing the fixing clamp to simultaneously hold and fix more cores 10. For example, each fixing surface 110 can have 3-16 fixing slots 111. Of course, other numbers of fixing slots 111 can also be formed on the fixing surface 110; this application does not impose a specific limitation. Preferably, the fixing surface 110 has 5, 6, 8, 10, or 12 fixing slots 111.
[0056] In one feasible implementation, such as Figure 3 As shown, the fixing groove 111 can be an open groove, facilitating the placement of the core 10. Furthermore, the width B of the fixing groove 111 decreases from the opening to the bottom along a third direction, for example, it can gradually decrease, thus making the fixing groove 111 suitable for clamping and fixing cores 10 of various specifications, with a wide range of applications. For example, the fixing groove 111 can be V-shaped, and three-point positioning is achieved through the two inner surfaces of the fixing groove 111 and the positioning element 220, effectively ensuring the stability of the clamping and fixing of the core 10.
[0057] In one feasible implementation, the width B1 of one end of the positioning member 220 used to press against the core 10 in the fixing groove 111 is smaller than the opening width B2 of the fixing groove 111. This means that the positioning member 220 can extend into the fixing groove 111, allowing the fixing clamp to hold the core 10 with a smaller outer diameter, thus having a wide range of applications. In this embodiment, the opening width B2 of the fixing groove 111 can refer to the local width of the fixing groove 111 and the positioning member 220 along a third direction. This can be understood as a groove being formed on the inner surface of the fixing groove 111 large enough for the positioning member 220 to extend into.
[0058] In one feasible implementation, such as Figure 4 and Figure 5As shown, the positioning member 220 includes a first positioning member 221 and a second positioning member 222. Specifically, the first positioning member 221 is provided with a first positioning plate 2211 at one end of the fixing groove 111. The first positioning plate 2211 is used to press against the core 10 in the fixing groove 111, and the width of the first positioning plate 2211 extends along the second direction to fix the core 10 in the second direction. The second positioning member 222 is provided with a second positioning plate 2221 at one end of the fixing groove 111, and the first positioning member 221 and the second positioning member 222 are spaced apart along the second direction. The second positioning member 222 is provided with a second positioning plate 2221 at one end of the second positioning member 222. The second positioning plate 2221 is used to press against the core 10 in the fixing groove 111, and the width of the second positioning plate 2221 extends along the first direction to fix the core 10 in the first direction. In this embodiment, when the core 10 is offset relative to the center of the fixing groove 111, the setting of the second positioning plate 2221 can effectively prevent the first positioning plate 2211 from eccentrically pressing against the core 10 and squeezing the core 10 to one side of the first positioning plate 2211, making it more convenient to clamp and fix the core 10.
[0059] In one feasible implementation, such as Figure 6 As shown, the end of the positioning member 220 connected to the first elastic member 230 is a stepped shaft with a stepped surface 2201. The first elastic member 230 is sleeved on the positioning member 220 and abuts against the stepped surface 2201. Furthermore, the side of the stepped portion 11 of the core 10 facing the positioning member 220 is a plane, and this plane is on the same plane as the tangent surface of the processing end facing the positioning member 220. Typically, when the core 10 is clamped and fixed by a fixing fixture, the first positioning plate 2211 abuts against the plane of the stepped portion 11 of the core 10 facing the positioning member 220.
[0060] In one feasible implementation, such as Figure 6 As shown, when the first elastic member 230 is in its natural state, the distance H1 between the first positioning plate 2211 and the fixing groove 111 is less than or equal to the distance H2 between the second positioning plate 2221 and the fixing groove 111. This can be understood as follows: when both the first positioning plate 2211 and the second positioning plate 2221 are separated from the core 10, the distance H1 between the first positioning plate 2211 and the fixing groove 111 is less than or equal to the distance H2 between the second positioning plate 2221 and the fixing groove 111. In this embodiment, when the movable block 210 moves towards the fixed block 100, the second positioning plate 2221 first presses against the contact core 10, more effectively preventing the first positioning plate 2211 from eccentrically pressing against the core 10 and squeezing the core 10 to one side of the first positioning plate 2211.
[0061] In one feasible implementation, such as Figure 4 and Figure 5As shown, multiple first elastic elements 230 are provided and connected one-to-one with the positioning elements 220. In one feasible embodiment, each positioning element 220 corresponding to a fixing groove 111 can also be connected to the same first elastic element 230, or all positioning elements 220 can be connected to the same first elastic element 230. Of course, the correspondence between the first elastic element 230 and the positioning element 220 can also be in other forms, which are not specifically limited in this application.
[0062] For example, the end of the first positioning member 221 facing away from the first positioning plate 2211 and the end of the second positioning member 222 facing away from the second positioning plate 2221 respectively abut against the corresponding first elastic member 230. Exemplarily, the elastic coefficient of the first elastic member 230 connected to the first positioning plate 2211 can be greater than or equal to the elastic coefficient of the first elastic member 230 connected to the second positioning plate 2221. Since the contact line length between the first positioning plate 2211 and the core 10 is greater than the contact line length between the second positioning plate 2221 and the core 10 along the second direction, the first positioning plate 2211 can more stably clamp and fix the core 10.
[0063] In one feasible implementation, such as Figure 7 As shown, the end of the second positioning plate 2221 is provided with an inner groove 2202, and the inner surface of the inner groove 2202 is used to press against the core 10 in the fixing groove 111. The inner groove 2202 can be an arc-shaped groove. In this embodiment, after the core 10 is placed in the fixing groove 111, it may not be in contact with the inner surface of the fixing groove 111, i.e., there is a gap between the core 10 and the inner surface of the fixing groove 111, and the core 10 may not be aligned with the fixing groove 111 along a third direction. During the movement of the movable block 210 towards the fixing block 100 along a third direction, the inner groove 2202 guides the movement of the core towards the fixing groove 111, i.e., the inner surface of the inner groove 2202 pushes against the core 10 towards the center of the fixing groove 111, effectively preventing the core 10 from being excessively squeezed by either the second positioning plate 2221 or the two inner surfaces of the fixing groove 111, thus avoiding scratches.
[0064] In this embodiment, reference is made to Figure 1 and Figure 8As shown, the fixing fixture also includes a platform 300, which has a first surface 310 on which a fixing block 100 is fixedly disposed. In this embodiment, when the core 10 is processed, the end of the core 10 facing away from the platform 300 is the end to be processed. The second positioning member 222 is disposed on the side of the first positioning member 221 facing the platform 300 along the second direction. The contact line length between the first positioning plate 2211 and the core 10 along the second direction is greater than the contact line length between the second positioning plate 2221 and the core 10 along the second direction, which can effectively ensure the stability of the end of the core 10 to be processed during processing, reduce the fluctuation of the end to be processed, and improve the processing accuracy.
[0065] Specifically, the first surface 310 of the platform 300 is provided with a first limiting groove 311, and the fixing block 100 is provided with a fixing part 120. The fixing part 120 is inserted into the first limiting groove 311 to achieve positioning and installation of the fixing part 120 relative to the platform 300. For example, the fixing block 100 can be fixed to the platform 300 by a first screw connector 410 for easy assembly.
[0066] Specifically, the fixing fixture also includes a wear-resistant block 420, which is disposed on the first surface 310, and the movable block 210 slides in contact with the wear-resistant block 420. The wear-resistant block 420 has a higher hardness than the platen 300. If the platen 300 and the movable block 210 were in direct contact, it might cause both the platen 300 and the movable block 210 to wear out too quickly, affecting the service life of the fixing fixture. By providing the wear-resistant block 420 on the first surface 310 of the platen 300, the service life of the fixing fixture is improved. For example, the wear-resistant block 420 can be fixed to the platen 300 using a second screw connector 430 for easy assembly.
[0067] In one feasible implementation, the plate platform 300 can be made of aluminum alloy. The aluminum alloy plate platform 300 reduces the weight of the fixing fixture and facilitates transfer. The wear-resistant block 420 can be made of alloy steel, among other things, and has good wear resistance.
[0068] In one feasible implementation, a first positioning groove 312 is formed on the first surface 310 of the platform 300, and a wear-resistant block 420 is disposed in the first positioning groove 312, effectively ensuring the structural compactness of the fixing fixture. For example, multiple first positioning grooves 312 and wear-resistant blocks 420 can be provided, each corresponding to one other.
[0069] In this embodiment, reference is made to Figure 8 and Figure 9 As shown, the plate platform 300 also has a second surface 320, which is arranged opposite to the first surface 310 along a second direction. The second surface 320 of the plate platform 300 is mounted facing the processing table of the processing equipment.
[0070] Specifically, the fixture also includes a clamping assembly 500, which fixes the fixture to the processing table.
[0071] Specifically, the clamping assembly 500 includes a positioning piece 510 and a clamping rivet 520 fixed on the second surface 320 of the plate table 300. The positioning piece 510 is provided with grooves and protrusions to cooperate with the processing table, so as to realize the positioning and installation of the plate table 300 and effectively ensure the verticality and overall parallelism of the fixing fixture. The clamping rivet 520 is used to connect with the processing table to achieve the purpose of fixing the plate table 300.
[0072] In this embodiment, reference is made to Figures 8 to 10 As shown, the positioning piece 510 can be fixed by a third screw connector 530. To extend the service life of the fixing fixture, a plurality of first reinforcing members 540 are provided on the first surface 310 of the platform 300. The plurality of third screw connectors 530 pass through the positioning piece 510 one by one and are threadedly connected to the first reinforcing members 540, thereby fixing the positioning piece 510. Specifically, the material of the first reinforcing member 540 includes, but is not limited to, alloy steel. In this embodiment, the design of the first reinforcing member 540 can effectively improve the fixing stability of the positioning piece 510, effectively avoid damage to the platform 300, increase the service life of the fixing fixture, and facilitate maintenance and replacement.
[0073] It is worth mentioning that the first reinforcing member 540 has a first extension 541, which extends to the second surface 320 of the plate 300 and abuts against the positioning piece 510, thereby further improving the fixing stability of the positioning piece 510.
[0074] For example, the first surface 310 of the platform 300 is provided with a plurality of second positioning grooves 313, which are respectively accommodated in a one-to-one manner for the first reinforcing member 540, so as to fix the first reinforcing member 540 while ensuring the structural compactness of the fixing fixture.
[0075] In this embodiment, reference is made to Figure 8 , Figure 9 and Figure 11 As shown, a second reinforcing member 550 is fixedly disposed on the first surface 310 of the platform 300. A clamping rivet 520 is threadedly connected to the second reinforcing member 550, thereby achieving the connection between the clamping rivet 520 and the platform 300. Specifically, the material of the second reinforcing member 550 includes, but is not limited to, alloy steel. In this embodiment, the design of the second reinforcing member 550 effectively improves the fixing stability of the clamping rivet 520, effectively avoids damage to the platform 300, increases the service life of the fixing fixture, and facilitates maintenance and replacement.
[0076] It is worth mentioning that the second reinforcing member 550 has a second extension 551, which extends to the second surface 320 of the plate 300, and can further improve the fixing stability of the clamping rivet 520.
[0077] Specifically, the second reinforcing member 550 is fixed to the plate 300 by multiple fourth screws 560 for easy assembly.
[0078] For example, the first surface 310 of the platform 300 is provided with a third positioning groove 314, which accommodates the second reinforcing member 550, thereby fixing the second reinforcing member 550 while ensuring the structural compactness of the fixing fixture.
[0079] In one feasible implementation, a single clamping assembly 500 is provided, located in the middle area of the platen 300. Of course, multiple clamping assemblies 500 may be provided, and the number and installation position of the clamping assemblies 500 depend on the size of the platen 300 and the actual working conditions. This application does not impose specific limitations.
[0080] In this embodiment, reference is made to Figure 12 As shown, the core 10 may be an irregular cylinder, and the end facing the plate 300 usually has a stepped portion 11. The outer diameter of the stepped portion 11 of the core 10 is larger than the outer diameter of the machining end. When the core 10 is clamped and fixed by the fixing fixture, in order to clamp the core 10, the fixing surface 110 of the fixing block 100 is provided with a relief groove 112 on the side facing the plate 300. The stepped portion 11 can be fixed in the relief groove 112 to avoid interference, so that the core 10 can be stably fixed in the fixing groove 111.
[0081] In one feasible implementation, a shim block 600 is provided on the plate 300. The shim block 600 is located between the movable block 210 and the fixed block 100. The core 10 is placed on the shim block 600. The stepped portion 11 is fixed by the inner surface of the shim block 600 and the relief groove 112, thereby achieving axial fixation of the core 10. This further improves the stability of the core 10 during processing and effectively ensures the perpendicularity and centerness of the core 10, thereby improving the processing accuracy of the core 10.
[0082] In this embodiment, reference is made to Figure 4 and Figure 13 As shown, the fixing fixture also includes a drive assembly 700 connected to the movable block 210. The drive assembly 700 is used to drive the movable block 210 to reciprocate along a third direction, so as to facilitate the clamping and fixing operation of the core 10.
[0083] Specifically, the drive assembly 700 includes a drive rod 710 and a second elastic member 720. The drive rod 710 includes a rod portion 711 and a pushing portion 712 disposed at a first end of the rod portion 711. The second end of the rod portion 711 slidably passes through the movable block 210 and is threadedly connected to the fixed block 100. The pushing portion 712 is used to push against the movable block 210. The second elastic member 720 is disposed between the movable block 210 and the fixed block 100. The second elastic member 720 is configured to provide a force for the movable block 210 to move away from the fixed block 100. In this embodiment, by rotating the drive rod 710 through the pushing part 712, the pushing part 712 pushes the movable block 210 towards the fixed block 100, thereby realizing the clamping action of the positioning member 220 on the core 10; by rotating the pushing part 712 in the opposite direction, the pushing part 712 moves away from the fixed block 100, and under the action of the second elastic member 720, the movable block 210 moves away from the fixed block 100, which is convenient and reliable to operate.
[0084] In one feasible implementation, the second elastic element 720 may be a spring.
[0085] In one possible implementation, the drive rod 710 can be a bolt.
[0086] In one feasible implementation, the drive component 700 may also be an electric cylinder, a pneumatic cylinder, etc., which are not specifically limited in this application.
[0087] In this embodiment, reference is made to Figure 4 , Figure 5 and Figure 13 As shown, the movable module 200 also includes a pressure block 240, which is disposed on the side of the movable block 210 facing away from the fixed block 100. The first end of the first elastic member 230 abuts against the pressure block 240, and the second end of the first elastic member 230 abuts against the positioning member 220, facilitating the assembly of the movable module 200. In a feasible embodiment, the movable block 210 and the pressure block 240 can be fixedly connected by a plurality of fifth screw connectors 250.
[0088] Specifically, in order to make the structure of the movable module 200 compact, multiple sliding grooves 211 are opened on the movable block 210. Through holes are opened on the bottom surface of the sliding groove 211. The positioning member 220 is slidably inserted in the sliding groove 211 and passes through the through hole. The position of the positioning member 220 is restricted by the bottom surface of the sliding groove 211, and the first elastic member 230 is also provided in the sliding groove 211.
[0089] Specifically, in order to make the structure of the movable module 200 compact, at least part of the first elastic member 230 is inserted into the interior of the fixed block 100 and the movable block 210.
[0090] In one possible implementation, the movable module 200 further includes a reinforcing block 260, which is disposed on the side of the pressure block 240 facing away from the movable block 210. A drive rod 710 slides through the reinforcing block 260, pressure block 240, and movable block 210 and is threadedly connected to the fixed block 100. The pushing part 712 pushes against the reinforcing block 260, causing the movable block 210 to move. Specifically, the hardness of the reinforcing block 260 is higher than that of the pressure block 240, effectively reducing wear and increasing the service life of the fixing fixture. Specifically, the material of the reinforcing block 260 can be alloy steel. Specifically, the reinforcing block 260 and the pressure block 240 can be fixedly connected by multiple sixth screw connectors 270.
[0091] To ensure the movement accuracy of the movable block 210, a guide rod 800 is provided between the fixed block 100 and the movable block 210. The guide rod 800 is configured to guide the movement of the movable block 210 in a third direction, effectively ensuring the movement stability of the movable block 210 and effectively preventing the positioning member 220 from scratching the core 10. In addition, to make the movable module 200 compact, the first elastic member 230 can be sleeved on the guide rod 800.
[0092] Specifically, there are two guide rods 800, which are located on opposite sides of the fixing block 100 along the first direction.
[0093] In one feasible embodiment, both movable blocks 210 are slidably connected to the guide rod 800, and the fixed block 100 is fixedly connected to the guide rod 800. Specifically, the guide rod 800 can be fixedly connected to the fixed block 100 by a threaded connection, facilitating assembly. Specifically, a sliding sleeve (not shown) can be provided inside the movable block 210, through which the guide rod 800 slides, facilitating maintenance and replacement and saving costs. In one feasible embodiment, the sliding sleeve can be replaced with a linear bearing or other components.
[0094] In one feasible implementation, the guide rod 800 is slidably connected to the fixed block 100, one of the two movable blocks 210 and the fixed block 100 are both slidably connected to the guide rod 800, and the other of the two movable blocks 210 is fixedly connected to the guide rod 800. Specifically, the guide rod 800 is a stepped shaft, and the end of the guide rod 800 that is fixedly connected to the movable block 210 is the larger end, that is, the diameter is larger than the other end. The movable block 210 has a second limiting groove 212, and the larger end of the guide rod 800 is disposed in the second limiting groove 212 and cooperates with the pressure block 240 to fix the guide rod 800.
[0095] Exemplary, the specific steps of using the fixing fixture provided in this embodiment are as follows: First, place the cores 10 one by one into the fixing grooves 111. Then, screw the pushing part 712 so that the pushing part 712 pushes the movable block 210 towards the fixing block 100, so that the positioning member 220 presses against the core 10, waiting for the core 10 to be processed. After the core 10 is processed, screw the pushing part 712 in the opposite direction so that the pushing part 712 moves away from the fixing block 100, and the movable block 210 moves away from the fixing block 100 under the action of the second elastic member 720, so as to achieve the purpose of disassembling the core 10.
[0096] In this embodiment, taking the V-shaped shape of the fixing groove 111 as an example, when placing the core 10, the core 10 is made to contact both inner surfaces of the fixing groove 111 to ensure successful subsequent fixing of the core 10. It is worth mentioning that if the core 10 has precision requirements, a shim 600 can be placed on the plate 300, and then the cores 10 can be placed one by one in the fixing groove 111.
[0097] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
