Description

Technical Field

[0001] This application relates to the field of fixture technology, and in particular to a positioning fixture and polishing assembly. Background Technology

[0002] The surface precision of the hinge shell of the folding phone is achieved through a polishing process, during which a polishing fixture is used for positioning. The polishing fixture includes a mounting plate, a middle plate, and clips. The mounting plate is used to mount the hinge shell, the middle plate is used to mount the clips, and the clips are used to limit the movement of the hinge shell. To ensure secure positioning, clips are provided on both sides of the hinge shell, and the clips are installed from top to bottom. Furthermore, to increase processing throughput, multiple products are vertically arranged during production.

[0003] To accommodate the installation requirements of top-down screw locking with clips, the middle plate between two vertically arranged products needs to be designed as a separate unit to allow space for screw installation and removal. However, this clip structure and installation method together increase the spacing between the vertically arranged products. Since the effective polishing height range of the polishing equipment is limited, the increased spacing reduces the number of stacked products that can be accommodated at one time, ultimately limiting the number of products that the equipment can polish at one time and restricting processing efficiency. Utility Model Content

[0004] This application provides a positioning fixture that improves the compactness of the fixture clamping the product, thereby at least partially solving the above-mentioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a positioning fixture is provided, comprising:

[0006] A multi-layer support member is arranged sequentially along the thickness direction of the support member, and at least one side of the support member in the width direction is used to place the workpiece;

[0007] A multi-layer mounting component is connected to both sides of the support component in the thickness direction, and one mounting component is disposed between two adjacent support components. The multi-layer mounting component includes two first mounting components and one or more second mounting components disposed between the two first mounting components.

[0008] Multiple limiting members are provided, and each of the mounting members is connected to at least one of the limiting members. The limiting members are used to limit the workpieces. The limiting members connected to the second mounting member are capable of limiting two adjacent workpieces along the thickness direction of the support member.

[0009] Optionally, the mounting member has a mounting groove on its side, and the limiting member includes a connecting part and a clamping part. The connecting part is partially inserted into the mounting groove, and the clamping part is connected to one end of the connecting part that protrudes from the mounting groove. The clamping part extends to the workpiece at least on one side along the thickness direction of the connecting part to limit the workpiece.

[0010] Optionally, the clamping portion extends into the limiting groove of the workpiece, and the polished surface of the workpiece protrudes from the clamping portion along the width direction of the support member.

[0011] Optionally, the positioning fixture further includes a first connector, the mounting member having a first connecting hole, the connecting part having a second connecting hole opposite to the first connecting hole, and the first connector being at least partially disposed in the first connecting hole and the second connecting hole.

[0012] Optionally, along the thickness direction of the support member, the connecting portion has a cleaning hole, and the clamping portion has a limiting surface facing the connecting portion and abutting against the workpiece. The limiting surface is coplanar with the wall of one side of the cleaning hole, and the width of the cleaning hole is not less than the width of the clamping portion.

[0013] Optionally, the positioning fixture further includes a second connector. Along the thickness direction of the support member, the support member has a third connecting hole, and the mounting member has a fourth connecting hole opposite to the third connecting hole. The second connector is at least partially disposed in the third connecting hole and the fourth connecting hole.

[0014] Optionally, the positioning fixture further includes a protective member, wherein at least one end of the support member is detachably connected to the protective member along the length direction of the support member, and the protective member protrudes from the support member and is disposed opposite to both ends of the workpiece.

[0015] Optionally, the protective component includes a rough polishing protective block and a fine polishing protective block that are detachably connected to the mounting component;

[0016] During the rough polishing of the workpiece, the rough polishing protection block is connected to the support member, and the rough polishing protection block can shield the transition surface and extension surface of the workpiece end;

[0017] During the fine polishing of the workpiece, the fine polishing protective block is connected to the support member, and the fine polishing protective block can cover the extended surface of the end of the workpiece;

[0018] During the wet polishing of the workpiece, the protective component separates from the support component.

[0019] Optionally, the positioning fixture further includes an assembly connector, which is detachably connected to the first mounting member and is used for positioning the positioning fixture by external components.

[0021] Polishing equipment;

[0022] A positioning fixture is detachably connected to the polishing equipment, and the positioning fixture is the positioning fixture described above.

[0023] In the positioning fixture of this application embodiment, by setting a mounting member between two supports, a limiting member for limiting the workpiece can be installed on the first and second mounting members. The limiting member on the second mounting member can simultaneously position two adjacent workpieces on the same side, thereby reducing the dimensions of the mounting member and the limiting member in the thickness direction of the supports and reducing the distance between the two workpieces. Therefore, without changing the overall height of the positioning fixture device, the entire positioning fixture can accommodate more workpieces on both sides of the support width direction, enabling the polishing equipment to process more workpieces in a single operation within the effective polishing height range, thus improving processing efficiency.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0045] According to the first aspect of this application, referring to Figure 1 and Figure 2A positioning fixture is provided, comprising a multi-layer support member 1, a multi-layer mounting member 2, and a plurality of limiting members 3. The multi-layer support member 1 is arranged sequentially along the thickness direction of the support member 1, and at least one side of the support member 1 in the width direction is used to place a workpiece 4. The multi-layer mounting member 2 is connected to both sides of the support member 1 in the thickness direction, and a mounting member 2 is disposed between two adjacent support members 1. The multi-layer mounting member 2 includes two first mounting members 21 and one or more second mounting members 22 disposed between the two first mounting members 21. Each mounting member 2 is connected to at least one limiting member 3, which is used to limit the workpiece 4. The limiting member 3 connected to the second mounting member 22 can limit two adjacent workpieces 4 along the thickness direction of the support member 1.

[0046] It is understood that the workpiece 4 is placed on at least one side of the width direction of the multi-layer support member 1, and the workpiece 4 is supported and positioned by the positioning structure; the mounting member 2 connects the support member 1 and the limiting member 3. The multi-layer mounting members 2 are respectively connected to both sides of the thickness direction of the support member 1, and one mounting member 2 is set between two adjacent support members 1. The two first mounting members 21 are located at the top and bottom layers of the mounting member 2, respectively, and one or more second mounting members 22 are located between the two first mounting members 21; the limiting member 3 is used to position the workpiece 4. Each mounting member 2 is connected to at least one limiting member 3, and the workpiece 4 is limited by cooperating with the workpiece 4. In particular, the limiting member 3 connected to the second mounting member 22, because it is located between two adjacent support members 1, can simultaneously limit two adjacent workpieces 4 along the thickness direction of the support member 1.

[0047] In some embodiments, by setting a mounting member 2 between two support members 1, a limiting member 3 can be installed on the first mounting member 21 and the second mounting member 22. The limiting member 3 on the second mounting member 22 can simultaneously position two adjacent workpieces 4 on the same side, reducing the number of limiting members 3 used and reducing the dimensions of the limiting member 3 and the mounting member 2 in the thickness direction of the support member 1, thus reducing the distance between the two workpieces 4. Therefore, without changing the total height of the positioning fixture, the entire positioning fixture can accommodate more workpieces 4 on both sides of the width direction of the support member 1, enabling the polishing equipment to process more workpieces 4 in a single operation within the effective polishing height range, thereby improving processing efficiency.

[0048] In some examples, refer to Figure 1The support component 1 has four layers (in practice, it can be set to two, three, or five layers according to production needs). The positioning fixture can position four workpieces 4 on one side and eight workpieces 4 on both sides. The mounting components 2 are set according to the number of support components 1. A first mounting component 21 is set at the top of the uppermost support component 1 and at the bottom of the lowermost support component 1. A second mounting component 22 is set between two adjacent support components 1 (one second mounting component 22 for two layers of support components 1, two second mounting components 22 for three layers of support components 1, three second mounting components 22 for four layers of support components 1, and so on). Each mounting component 2 is equipped with a limiter 3. One limiter 3 can be set in the middle of the mounting component 2, one at each end of the mounting component 2, or one in the middle and one at each end of the mounting component 2. The specific number can be flexibly selected. It should be noted that the limiting member 3 on the first mounting member 21 can protrude from one side to limit the workpiece 4, or it can protrude from both sides. In this case, it has the same structure as the limiting member 3 on the second mounting member 22 and has good interchangeability.

[0049] Reference Figures 3 to 5 In some embodiments, the mounting member 2 is provided with a mounting groove 23 on its side, and the limiting member 3 includes a connecting part 31 and a clamping part 32. The connecting part 31 is partially inserted into the mounting groove 23, and the clamping part 32 is connected to one end of the connecting part 31 that protrudes from the mounting groove 23. The clamping part 32 extends to the workpiece 4 at least on one side along the thickness direction of the connecting part 31 to limit the workpiece 4.

[0050] It is understandable that the mounting groove 23 on the side of the mounting part 2 provides an installation position for the limiting part 3, and its shape and size are adapted to the connecting part 31 of the limiting part 3 to ensure that the connecting part 31 can be stably inserted; the connecting part 31 of the limiting part 3 is connected to the mounting part 2 by partially inserting into the mounting groove 23, and provides support for the clamping part 32; the clamping part 32 is connected to one end of the connecting part 31 that protrudes from the mounting groove 23, and extends to the workpiece 4 at least on one side along the thickness direction of the connecting part 31, and forms a limit by contacting the workpiece 4.

[0051] In some embodiments, by providing a mounting groove 23 on the side of the mounting member 2, the connecting part 31 of the limiting member 3 is partially inserted into the mounting groove 23, so that the limiting member 3 and the mounting member 2 are firmly connected; at the same time, the structure in which the clamping part 32 extends to the workpiece 4 along at least one side of the thickness direction of the connecting part 31 can flexibly adjust the limiting direction according to the position of the workpiece 4, so as to ensure the limiting effect on the workpiece 4.

[0052] In some examples, refer to Figure 3 Mounting component 2 has a clearance groove at the corner of mounting slot 23.

[0053] It is understandable that a clearance groove is provided at the corner of the mounting groove 23 of the mounting component 2. The clearance groove is a recessed area formed on the basis of the original corner structure of the mounting groove 23. It provides clearance space for the connecting part 31 of the limiting component 3 to be inserted into the mounting groove 23, reduces the interference and friction between the connecting part 31 and the corner of the mounting groove 23, reduces the operating resistance of the limiting component 3 during installation, makes the insertion and position adjustment of the limiting component 3 smoother, and improves the assembly efficiency of the limiting component 3 and the mounting component 2.

[0054] Reference Figure 2 and Figure 4 In some embodiments, the clamping part 32 extends into the limiting groove 41 of the workpiece 4, and the polished surface 42 of the workpiece 4 protrudes from the clamping part 32 along the width direction of the support member 1.

[0055] It is understandable that the clamping part 32 of the limiting member 3 extends into the limiting groove 41 of the workpiece 4, and the workpiece 4 is positioned by cooperating with the limiting groove 41, thereby reducing the offset of the workpiece 4 during the polishing process; along the width direction of the support member 1, the polishing surface 42 of the workpiece 4 protrudes from the clamping part 32, leaving enough space for subsequent polishing operations, and ensuring that the polishing equipment can directly contact the polishing surface 42 of the workpiece 4.

[0056] In some embodiments, by extending the clamping part 32 into the limiting groove 41 of the workpiece 4, the cooperation between the limiting groove 41 and the clamping part 32 improves the limiting stability of the workpiece 4 and reduces the displacement of the workpiece 4 during polishing. Furthermore, the clamping part 32, located within the limiting groove 41, prevents it from protruding beyond the polished surface 42 of the workpiece 4. By making the polished surface 42 of the workpiece 4 protrude beyond the clamping part 32 along the width direction of the support member 1, the clamping part 32 is prevented from obstructing the polished surface 42, ensuring that the polishing equipment can process the polished surface 42 comprehensively and without obstruction. This guarantees polishing accuracy and eliminates the need to adjust the polishing path to avoid the clamping part 32, improving the smoothness and efficiency of the polishing operation.

[0057] Reference Figures 3 to 5 In some embodiments, the positioning fixture further includes a first connector 5, the mounting member 2 has a first connecting hole 24, the connecting part 31 has a second connecting hole 311 opposite to the first connecting hole 24, and the first connector 5 is at least partially disposed in the first connecting hole 24 and the second connecting hole 311.

[0058] It is understandable that the first connecting member 5 of the positioning fixture is used to reinforce the connection between the mounting member 2 and the limiting member 3. The first connecting hole 24 opened on the mounting member 2 and the second connecting hole 311 opened on the connecting part 31 are in corresponding positions. Together, they provide a passage for the first connecting member 5. The first connecting member 5 is at least partially located in the first connecting hole 24 and the second connecting hole 311 at the same time. Through the cooperation with the hole wall, the mounting member 2 and the limiting member 3 are fixedly connected.

[0059] When installing the limiting member 3 and the mounting member 2, after the connecting part 31 of the limiting member 3 is inserted into the mounting groove 23 and the clamping part 32 is adjusted to the correct position, the first connecting hole 24 and the second connecting hole 311 are aligned. Then, the first connecting member 5 is inserted into the first connecting hole 24 and the second connecting hole 311 to complete the fixing of the mounting member 2 and the limiting member 3. During the polishing operation, when the limiting member 3 is subjected to an external force transmitted by the workpiece 4, the first connecting member 5, through its own force against the hole wall, prevents the mounting member 2 and the limiting member 3 from moving relative to each other, maintaining their connection.

[0060] In some embodiments, by providing a first connecting member 5, and cooperating with the first connecting hole 24 of the mounting member 2 and the second connecting hole 311 of the connecting part 31, a rigid connection is added between the mounting member 2 and the limiting member 3 on the basis of the insertion, improving the stability of the connection between the two and reducing the loosening of the limiting member 3 due to vibration during the polishing process. At the same time, this detachable connection method facilitates the replacement and maintenance of the limiting member 3. When the limiting member 3 is worn or needs to be adapted to different workpieces 4, it can be quickly replaced by disassembling the first connecting member 5, enhancing the versatility and service life of the fixture.

[0061] In some examples, refer to Figure 3 The first connecting part 5 is a fastener such as a screw or a pin.

[0062] Understandably, the fasteners can be adapted to the first connecting hole 24 of the mounting part 2 and the second connecting hole 311 of the connecting part 31. The screws achieve detachable fixing through the engagement of their threads with the hole wall, while the pins form a positioning connection through an interference or transition fit with the hole wall. Regardless of the type, both can meet the installation requirements of the first connecting part 5 being at least partially disposed in the first connecting hole 24 and the second connecting hole 311, providing a stable connection between the mounting part 2 and the limiting part 3.

[0063] In some embodiments, common fasteners such as screws and pins are selected as the first connecting member 5, eliminating the need to design a special structure for the first connecting member 5 and reducing the manufacturing cost of the fixture; at the same time, the detachability of the fasteners facilitates the subsequent replacement or maintenance of the limiting member 3.

[0064] In some examples, refer to Figure 3 The first connecting hole 24 and the second connecting hole 311 are provided along the thickness, width or length of the mounting part 2.

[0065] Understandably, the first connecting hole 24 of the mounting part 2 and the second connecting hole 311 of the connecting part 31 are flexibly oriented, and can be set along the thickness direction, width direction, or length direction of the mounting part 2. The specific direction is determined according to the overall structure of the positioning fixture, the installation requirements of the workpiece 4, and the type of the first connecting part 5. Regardless of the direction, the two always remain in relative positions to ensure that the first connecting part 5 can be installed smoothly. When determining the orientation of the first connecting hole 24 and the second connecting hole 311, if it is necessary to hide the first connecting part 5, a hole can be drilled along the thickness direction. If it is necessary to facilitate disassembly and assembly, a hole can be drilled along the width or length direction of the mounting part 2, and it can be set as a countersunk hole to hide the head of the first connecting part 5, such as screws or bolts.

[0066] Reference Figure 4 and Figure 5 In some embodiments, along the thickness direction of the support member 1, the connecting part 31 is provided with a cleaning hole 312, and the clamping part 32 has a limiting surface facing the connecting part 31 and abutting against the workpiece 4. The limiting surface is coplanar with the hole wall on one side of the cleaning hole 312, and the width of the cleaning hole 312 is not less than the width of the clamping part 32.

[0067] It is understandable that a cleaning hole 312 is provided in the connecting part 31 along the thickness direction of the support member 1. The cleaning hole 312 is a channel that passes through the connecting part 31, and one side of its hole wall is coplanar with the limiting surface of the clamping part 32, so as to ensure that the cleaning tool can pass smoothly through the cleaning hole 312 to clean the clamping part 32.

[0068] When cleaning the positioning fixture, the cleaning tool is inserted into the cleaning hole 312 of the connecting part 31 along the thickness direction of the limiting member 3. Since the cleaning hole 312 is wide enough, the cleaning tool can clean the polishing debris, polishing wax and other residues in the clamping part 32 and the surrounding area. During the cleaning process, the cleaning hole 312 provides cleaning operation space, and the force generated when the tool contacts the clamping part 32 is small.

[0069] In some embodiments, a cleaning hole 312 is provided in the connecting part 31, and the width of the cleaning hole 312 is not less than the width of the clamping part 32, so as to provide a channel for cleaning operation, facilitate the tool to deeply clean the dirt near the clamping part 32, and keep the fixture clean; at the same time, the cleaning hole 312 provides cleaning operation space, the force generated when the tool contacts the clamping part 32 is small, the clamping part 32 is not easy to deform during cleaning, and the limiting accuracy is maintained.

[0070] Reference Figure 3 and Figure 6 In some embodiments, the positioning fixture further includes a second connector 6. Along the thickness direction of the support member 1, the support member 1 has a third connecting hole 11, and the mounting member 2 has a fourth connecting hole 25 that is opposite to the third connecting hole 11. The second connector 6 is at least partially disposed in the third connecting hole 11 and the fourth connecting hole 25.

[0071] Understandably, the second connector 6 of the positioning fixture is used to connect and fix the support 1 and the mounting 2. Along the thickness direction of the support 1, the support 1 has a third connecting hole 11 and the mounting 2 has a fourth connecting hole 25. The third connecting hole 11 and the fourth connecting hole 25 are positioned correspondingly and together provide installation space for the second connector 6. The second connector 6 is at least partially located in both the third connecting hole 11 and the fourth connecting hole 25 at the same time. Through the cooperation with the walls of the two holes, the support 1 and the mounting 2 are firmly connected to ensure that the two do not shift relative to each other during the polishing process.

[0072] In some embodiments, by providing a second connecting member 6, which cooperates with the third connecting hole 11 of the support member 1 and the fourth connecting hole 25 of the mounting member 2, a reliable connection is formed between the support member 1 and the mounting member 2, improving the overall stability of the positioning fixture and reducing the impact of component loosening on the positioning accuracy of the workpiece 4 during processing. Simultaneously, the connection method of the second connecting member 6 and the connecting hole facilitates the disassembly and assembly of the support member 1 and the mounting member 2. When it is necessary to replace the support member 1 or the mounting member 2 with different specifications, quick replacement can be achieved by disassembling the second connecting member 6, enhancing the fixture's versatility and maintenance convenience.

[0073] In some examples, one of the support member 1 and the mounting member 2 is provided with a protrusion, and the other is provided with a groove that engages with the protrusion.

[0074] It is understandable that the support 1 and the mounting 2 are connected by the cooperation of the protrusion and the groove. The protrusion is set on one of the components of the support 1 or the mounting 2, and the groove is set on the other component. The shape and size of the groove are adapted to the protrusion to ensure that the protrusion can be stably inserted into the groove. The connection and positioning between the support 1 and the mounting 2 are formed by the interlocking action of the two.

[0075] In some embodiments, by providing a protrusion in one of the support member 1 and a matching groove in the other, the connection between the two is achieved by the engagement of the protrusion and the groove, which simplifies the connection operation process and improves the assembly efficiency of the support member 1 and the mounting member 2.

[0076] Reference Figure 3 In some embodiments, the positioning fixture further includes a protective member 7. Along the length of the support member 1, at least one end of the support member 1 is detachably connected to the protective member 7. The protective member 7 protrudes from the support member 1 and is disposed opposite to both ends of the workpiece 4.

[0077] It is understandable that the protective component 7 is used to protect the ends of the workpiece 4. Along the length of the support component 1, at least one end of the support component 1 is detachably connected to the protective component 7. After installation, the protective component 7 protrudes from the support component 1 and is positioned opposite to the two ends of the workpiece 4. Through its own structure, it blocks external equipment from directly acting on the ends of the workpiece 4, thus forming physical protection for the ends of the workpiece 4.

[0078] When installing the protective component 7, depending on the area of ​​the workpiece 4 that needs protection, select one or both ends of the support component 1 along its length to install the protective component 7. Fix the protective component 7 to the support component 1 using a detachable connection, ensuring that the portion of the protective component 7 protruding from the support component 1 is opposite to both ends of the workpiece 4. During the polishing operation, when the polishing equipment or other components approach the end of the workpiece 4, the protective component 7 contacts the external component before the end of the workpiece 4, preventing it from directly contacting the end of the workpiece 4. After the operation is completed, the protective component 7 can be removed for cleaning or replacement.

[0079] In some embodiments, by providing a protective element 7, which is detachably connected to the support element 1 and protrudes from the support element 1 and opposite to both ends of the workpiece 4, the direct impact or friction of external equipment on the ends of the workpiece 4 can be effectively blocked, thereby protecting the ends of the workpiece 4 and reducing end damage. At the same time, the detachable design facilitates the replacement and maintenance of the protective element 7. When the protective element 7 is worn, it can be replaced in time to ensure the protective effect. Furthermore, the appropriate protective element 7 can be flexibly selected according to different processes, enhancing the versatility of the fixture.

[0080] Reference Figure 3 In some embodiments, the protective element 7 includes a rough polishing protective block and a fine polishing protective block that are detachably connected to the mounting element 2; when the workpiece 4 is rough polished, the rough polishing protective block is connected to the support element 1 and can shield the transition surface and extension surface at the end of the workpiece 4; when the workpiece 4 is fine polished, the fine polishing protective block is connected to the support element 1 and can shield the extension surface at the end of the workpiece 4; when the workpiece 4 is wet polished, the protective element 7 is separated from the support element 1.

[0081] Understandably, the protective component 7 includes a rough polishing protective block and a fine polishing protective block, both used to protect the ends of the workpiece 4. The structure of the rough polishing protective block can block the transition surface and extension surface of the workpiece 4 ends, while the structure of the fine polishing protective block can only block the extension surface of the workpiece 4 ends. Both types of protective blocks are detachably connected to the support component 1, and can be installed or removed according to different polishing processes.

[0082] During the rough polishing process, the rough polishing protective block is connected to the support 1 to cover the transition surface and extension surface at the end of the workpiece 4. During the fine polishing process, the fine polishing protective block is replaced and connected to the support 1, covering only the extension surface at the end of the workpiece 4, allowing the transition surface to be finely polished. During the wet polishing process, the protective block 7 is removed from the support 1, separating the protective block from the support 1, allowing the transition surface and extension surface to be wet polished.

[0083] In some embodiments, by coordinating the rough polishing protection block and the fine polishing protection block, the workpiece ends 4 are fully protected during rough polishing, the transition surface is selectively exposed for processing during fine polishing, and the protection block 7 is removed during wet polishing to process the entire area. This satisfies the differentiated processing requirements of different processes for the workpiece ends 4, protecting areas that do not need to be processed while ensuring that areas that need to be processed can be effectively handled, thereby improving the processing accuracy and efficiency of each process.

[0084] In some examples, refer to Figure 3 The protective component 7 is connected to the support component 1 by fasteners such as bolts and screws, and the protective component 7 has countersunk holes for installing fasteners.

[0085] Reference Figure 7 and Figure 8 In some embodiments, the positioning fixture further includes an assembly connector 8, which is detachably connected to the first mounting member 21 and is used for positioning external components in the positioning fixture.

[0086] Understandably, the assembly connector 8 is used to cooperate with external components to achieve the overall positioning of the fixture. The assembly connector 8 is detachably connected to the first mounting member 21. The assembly connector 8 can be provided only on the top of the top first mounting member 21, or only on the bottom of the bottom first mounting member 21, or on both first mounting members 21. The assembly connector 8 is adapted to the external positioning component and provides a positional reference for the positioning fixture through cooperation with the external component, ensuring that the fixture is in the preset position during processing.
