Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a scraper machining fixture. Background Technology

[0002] PEEK material is often used to manufacture high-performance scrapers due to its excellent wear resistance, self-lubricating properties, mechanical strength, and chemical resistance. However, these excellent properties also make PEEK material difficult to process, and traditional processing methods have many drawbacks.

[0003] Currently, when manufacturing PEEK scrapers, general-purpose vises or simple custom fixtures are typically used for clamping. Because scraper parts usually have many machined surfaces and complex shapes, the process is quite cumbersome. Traditional machining methods have the following drawbacks: First, low machining efficiency, as each part requires multiple clamping and positioning operations to complete machining of all surfaces, resulting in high changeover and adjustment time. Second, difficulty in guaranteeing machining accuracy, as multiple clamping inevitably introduces repetitive positioning errors, making it difficult to meet the dimensional and geometric tolerances specified in the drawings, leading to a low product qualification rate. Third, high technical requirements for operators, as the machining process heavily relies on operator experience, resulting in significant human influence and poor product quality stability. Finally, difficulty in achieving mass production, as traditional clamping and machining methods limit the improvement of production cycle time and cannot meet the demands of modern mass production.

[0004] Therefore, the existing technology lacks a special fixture that can specifically address the multi-faceted machining characteristics of PEEK scrapers, enabling convenient clamping, multi-faceted machining, and effectively ensuring accuracy and improving efficiency.

[0005] A search revealed a Chinese patent document that discloses an easily adjustable multi-angle machining fixture [Application No.: 202421456996.2, Publication No.: CN222831776U]. This fixture includes a mounting plate and a fixture body. The fixture body is located on the upper side of the mounting plate, and a fixing shell is fixedly mounted on the upper surface of the mounting plate. A turntable is rotatably mounted on the upper surface of the fixing shell. Although this patent adapts to the needs of different machining surfaces through the multi-angle rotation function of the fixture itself, the material changing operation is complicated and the maintenance cost is high, making it unsuitable for large-scale, high-precision machining. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a scraper processing fixture.

[0007] A scraper processing fixture includes a mounting base and a fixture platform, characterized in that: the fixture platform is disposed on top of the mounting base; The fixture table has a first workstation on one side and a second workstation on the other side; The first workstation includes a first positioning base surface, and a first positioning hole is formed on the first positioning base surface; The second station includes a second positioning base surface, and a second positioning hole is formed on the second positioning base surface; The axis of the first positioning hole is perpendicular to the first positioning base surface, and the axis of the second positioning hole is perpendicular to the second positioning base surface.

[0008] Preferably, the first positioning base surface is a plane and forms an acute angle with the bottom surface of the fixture table.

[0009] The above technical solution can ensure that the surface to be processed by the scraper is as horizontal as possible during the processing, simplifying the operation steps, reducing the processing difficulty, and improving the processing effect and accuracy.

[0010] Specifically, the acute angle formed by the first positioning base surface and the bottom surface of the fixture table allows the surface of the scraper to be machined to automatically adjust to a near-horizontal position during installation and processing, thereby avoiding uneven processing or errors caused by tilting. This structure allows the machining tool to better fit the workpiece surface, making it easier to operate and further reducing the adverse effects caused by angular deviations.

[0011] In practical applications, this design not only improves the ease of operation of scraper processing and reduces worker adjustment time, but also ensures the stability and consistency of processing quality. It is of great significance for improving product precision, optimizing production processes, and guaranteeing processing efficiency.

[0012] Preferably, the second positioning base surface is a contoured surface that matches the shape of the scraper, and forms an acute angle with the bottom surface of the fixture table.

[0013] The above technical solution enables the scraper to precisely fit the positioning base surface during processing, ensuring that the scraper maintains a reasonable posture during operation, thereby reducing processing difficulty and improving processing effect.

[0014] Specifically, by using a contoured surface that matches the shape of the scraper, not only can precise positioning of scrapers of different shapes be achieved, but also workpiece wobbling or shifting during clamping can be prevented. Combined with the acute angle formed with the bottom surface of the fixture table, the scraper can be kept more horizontal during processing, making it easier for operators to perform process handling and effectively improving the stability and consistency of processing.

[0015] In practical applications, this structural design can adapt to the processing needs of scrapers of various shapes, significantly improving clamping efficiency and accuracy. At the same time, it helps maintain uniform force on all parts of the scraper during processing, reducing workpiece damage or processing errors caused by improper clamping, which is of great significance for ensuring processing quality and product consistency.

[0016] Preferably, the cross-section of the mounting base is convex, and the longitudinal section of the fixture table is geometric.

[0017] The above technical solutions not only improve the overall structural strength and stability of the fixture, providing a solid foundation for scraper processing, but also achieve a foolproof design, further ensuring the correct installation direction and orientation of the fixture table.

[0018] Specifically, the convex cross-section of the mounting base and the trapezoidal longitudinal section of the fixture table complement each other, effectively defining the assembly position of the fixture table. This complementary structure prevents confusion regarding installation direction, eliminating process problems caused by incorrect orientation. This foolproof design allows operators to quickly and accurately position the fixture table during assembly, significantly reducing the risk of human error.

[0019] In practical applications, the optimized structure of the base and fixture not only enhances the stability and durability of the equipment but also ensures consistent orientation and position during each installation, further improving processing accuracy and efficiency. This solution effectively improves the safety and reliability of the production process, which is of great significance for ensuring product quality and standardized workshop management.

[0020] Preferably, a tool edge protection groove is provided at the junction of the first positioning base surface and the protrusion of the fixture table; a tool edge protection groove is provided at the junction of the second positioning base surface and the protrusion of the fixture table.

[0021] The above technical solution can effectively prevent direct contact between the fixture table and the blade edge, avoiding blade edge damage and fixture table wear caused by collision and friction during assembly, clamping or operation, thereby effectively protecting the integrity of key parts and extending the service life of equipment and tools.

[0022] Specifically, the edge protection groove provides a safe isolation space between the cutting edge and the fixture table. Even with minor machining tolerances, misalignments, or operational deviations during assembly, the edge will not collide or press against the fixture table, ensuring the sharpness and performance of the scraper. At the same time, the protection groove optimizes the tolerance for clamping operations, improves the safety and reliability of the production process, and reduces maintenance, repair, and replacement costs.

[0023] This technical solution can not only significantly improve product quality and service life, but also help to achieve safe and efficient production operations, which is of great significance for ensuring the long-term stable operation of precision machining equipment.

[0024] Preferably, the first workstation and the second workstation are arranged symmetrically about the central longitudinal axis of the fixture table.

[0025] The above technical solutions can effectively improve the overall structural balance of the jig table, making the force distribution of each station more uniform during operation, reducing the phenomenon of off-center loading, and thus ensuring the stability and safety of the jig table and related processing components.

[0026] Specifically, a symmetrical arrangement along the central longitudinal axis optimizes the space utilization of the fixture table, ensuring that the first and second workstations have identical operating conditions and clamping environments, facilitating workstation interchange and synchronous processing. Furthermore, the symmetrical layout simplifies the clamping process, improves positioning accuracy and consistency, reduces processing errors caused by uneven arrangement, and further enhances production efficiency and product quality.

[0027] This technical solution also facilitates the standardized design and mass production of the jig, enhances the versatility and flexibility of the jig, provides convenient conditions for equipment maintenance and upgrades, and is of great value for achieving efficient, standardized and reliable production management.

[0028] Preferably, the fixture table is detachably connected to the mounting base by bolts.

[0029] The above technical solution enables convenient disassembly and efficient maintenance between the jig platform and the mounting base. The bolt-detachable connection design allows for quick separation of the jig platform when it is damaged, needs cleaning, or requires replacement, simply by loosening the bolts, greatly improving the flexibility and efficiency of equipment maintenance.

[0030] Specifically, this bolt-detachable connection method is not only simple in structure and reliable in installation, but also facilitates subsequent disassembly and adjustment. When the fixture needs to be changed or its position adjusted, it can be easily done with conventional tools without complicated processes, effectively shortening maintenance and adjustment time. In addition, the bolt connection ensures the stability of the connection points, preventing loosening due to equipment vibration, and ensuring the stability and safety of the production process.

[0031] In practical applications, this detachable connection solution is particularly suitable for production environments that require frequent replacement or inspection of fixtures, facilitating standardized and modular equipment management. By simplifying the disassembly and installation process, it not only improves maintenance efficiency but also reduces labor costs, which is of great significance for enhancing the flexibility and operational efficiency of the production line.

[0032] Compared with the prior art, the present invention has the following advantages: 1. This utility model fixture cleverly integrates the first and second workstations onto a single fixture platform, centralizing the processing of two key steps in the scraper's machining. Operators only need to perform one clamping and positioning operation to sequentially process both sides of the scraper, or achieve assembly line operation through alternating clamping, significantly reducing auxiliary time spent on repeated disassembly, assembly, and workpiece alignment. This design effectively reduces the operator's workload, simplifies the processing flow, and facilitates mass production of scrapers, contributing to improved overall production efficiency.

[0033] 2. The design of this fixture focuses on ensuring the stability and consistency of the machining process. Its specific angular base surface at the first station and the contoured base surface at the second station, combined with precise positioning holes, provide stable and highly repeatable clamping and positioning for the scraper blank and its semi-finished product. This structure helps reduce the cumulative errors that may be introduced by multiple clamping operations, lowers the risk of workpieces exceeding tolerances due to unstable positioning, provides excellent process assurance for the machining accuracy of the scraper's key dimensions and shapes, and is conducive to improving the product yield.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 2 This utility model provides a technical solution: A scraper processing fixture includes a mounting base 1 and a fixture platform 2, characterized in that: the fixture platform 2 is disposed on the top of the mounting base 1; The fixture table 2 has a first workstation on one side and a second workstation on the other side; The first work station includes a first positioning base surface 31, and a first positioning hole 32 is provided on the first positioning base surface 31. The second station includes a second positioning base surface 41, on which a second positioning hole 42 is provided; The axis of the first positioning hole 32 is perpendicular to the first positioning base surface 31, and the axis of the second positioning hole 42 is perpendicular to the second positioning base surface 41.

[0038] The operation process is as follows: First, the operator installs and fixes the scraper processing fixture described in this utility model onto the worktable of the machining center via the mounting base 1, and then installs the fixture table 2. After that, the scraper processing cycle can begin.

[0039] Step 1: Process the first side of the scraper Place the PEEK scraper blank to be processed on the first station of the fixture table 2, ensuring that the bottom surface of the blank is in contact with the first positioning base surface 31, and that the pre-machined positioning holes on the blank are aligned with the first positioning holes 32. At this time, a positioning pin or a special clamping mechanism (not shown in the figure) from the machining center can be used to pass through the first positioning holes 32 and clamp the blank in place. After clamping, start the machining program, and the first surface of the scraper will be milled by the machining center tool.

[0040] Step 2: Change workstations and process the second side of the scraper. After the first side is processed, the clamping mechanism is released, and the semi-finished scraper with the first side processed is moved out of the first workstation. It is then transferred to the second workstation. At this point, the processed first side serves as a reference, fitting against the contoured surface of the second positioning base 41. Similarly, the positioning holes on the scraper are aligned with the second positioning holes 42 for positioning and clamping. Since the second positioning base 41 is a contoured surface designed based on the final shape of the first side of the scraper, rapid and precise positioning can be achieved. After clamping, the processing program is restarted to process the second side of the scraper.

[0041] Cyclic operation At this point, a complete scraper processing cycle is finished. The operator can remove the finished product and load a new blank into the first station. Simultaneously, the semi-finished product with the first side already processed at the first station is moved to the second station. This cycle is repeated to achieve simultaneous operation of the two stations and continuous batch production of scrapers. Throughout the process, the tool edge protection groove of the fixture table 2 effectively prevents interference between the tool or workpiece and the fixture.

[0042] Specifically, the first positioning base 31 is a plane and forms an acute angle with the bottom surface of the fixture table 2, which can ensure that the surface to be processed by the scraper is as horizontal as possible during the processing, simplifying the operation steps, reducing the processing difficulty, and improving the processing effect and accuracy.

[0043] Specifically, the acute angle formed by the first positioning base surface 31 and the bottom surface of the fixture table 2 allows the surface of the scraper to be processed to automatically adjust to a near-horizontal position during installation and processing, thereby avoiding uneven processing or errors caused by tilting. This structure allows the processing tool to better fit the workpiece surface, making it easier to operate and further reducing the adverse effects caused by angular deviations.

[0044] In practical applications, this design not only improves the ease of operation of scraper processing and reduces worker adjustment time, but also ensures the stability and consistency of processing quality. It is of great significance for improving product precision, optimizing production processes, and guaranteeing processing efficiency.

[0045] Specifically, the second positioning base surface 41 is a contoured surface that matches the shape of the scraper and forms an acute angle with the bottom surface of the fixture table 2. This allows the scraper to precisely fit the positioning base surface during processing, ensuring that the scraper maintains a reasonable posture during operation, thereby reducing processing difficulty and improving processing effect.

[0046] Specifically, by using a contoured surface that matches the shape of the scraper, not only can precise positioning of scrapers of different shapes be achieved, but also workpiece wobbling or shifting during clamping can be prevented. Combined with the acute angle formed with the bottom surface of the fixture table 2, the scraper can be kept more horizontal during processing, making it easier for operators to perform process handling and effectively improving the stability and consistency of processing.

[0047] In practical applications, this structural design can adapt to the processing needs of scrapers of various shapes, significantly improving clamping efficiency and accuracy. At the same time, it helps maintain uniform force on all parts of the scraper during processing, reducing workpiece damage or processing errors caused by improper clamping, which is of great significance for ensuring processing quality and product consistency.

[0048] Specifically, the mounting base 1 has a convex cross-section, and the fixture table 2 has a geometric cross-section. This not only improves the overall structural strength and stability of the fixture and provides a solid foundation for scraper processing, but also achieves a foolproof design, further ensuring the correct installation direction and orientation of the fixture table 2.

[0049] Specifically, the convex cross-section of the mounting base 1 and the trapezoidal longitudinal section of the fixture table 2 complement each other, effectively defining the assembly position of the fixture table 2. This complementary structure prevents confusion regarding the installation direction, eliminating process problems caused by incorrect orientation. This foolproof design allows operators to quickly and accurately position the fixture table 2 during assembly, significantly reducing the risk of human error.

[0050] In practical applications, the structural optimization of the base and fixture table 2 not only enhances the stability and durability of the equipment but also ensures consistent orientation and position during each installation, further improving processing accuracy and efficiency. This solution effectively improves the safety and reliability of the production process, which is of great significance for ensuring product quality and standardized workshop management.

[0051] Specifically, a blade edge protection groove is provided at the junction of the first positioning base 31 and the protrusion of the fixture table 2; a blade edge protection groove is also provided at the junction of the second positioning base 41 and the protrusion of the fixture table 2. This effectively prevents direct contact between the fixture table 2 and the blade edge of the scraper, avoiding blade edge damage and fixture table 2 wear caused by collision and friction during assembly, clamping, or operation, thereby effectively protecting the integrity of key parts and extending the service life of equipment and tools.

[0052] Specifically, the edge protection groove provides a safe isolation space between the cutting edge and the fixture table 2. Even with minor machining tolerances, misalignments, or operational deviations during assembly, the edge will not collide or press against the fixture table 2, ensuring the sharpness and performance of the scraper. At the same time, the protection groove optimizes the tolerance for clamping operations, improves the safety and reliability of the production process, and reduces maintenance, repair, and replacement costs.

[0053] This technical solution can not only significantly improve product quality and service life, but also help to achieve safe and efficient production operations, which is of great significance for ensuring the long-term stable operation of precision machining equipment.

[0054] Specifically, the first and second workstations are symmetrically arranged about the central longitudinal axis of the fixture table 2, which can effectively improve the overall structural balance of the fixture table 2, make the force distribution of each workstation more uniform during operation, reduce the phenomenon of off-center loading, and thus ensure the stability and safety of the fixture table 2 and related processing components.

[0055] Specifically, the symmetrical arrangement along the central longitudinal axis optimizes the space utilization of the fixture table 2, ensuring that the first and second workstations have the same operating conditions and clamping environment during operation, facilitating workstation interchange and synchronous processing. Furthermore, the symmetrical layout simplifies the clamping process, improves positioning accuracy and consistency, reduces processing errors caused by uneven arrangement, and further enhances production efficiency and product quality.

[0056] This technical solution also facilitates the standardized design and mass production of the jig table 2, enhances its versatility and flexibility, provides convenient conditions for equipment maintenance and upgrades, and is of great value for achieving efficient, standardized and reliable production management.
