Description

Technical Field

[0001] This utility model relates to the field of precision metal parts processing equipment, specifically a high-efficiency electrode grinding and clamping fixture. Background Technology

[0002] Pure tungsten electrodes are currently widely used in various fields. However, their grinding process suffers from problems such as low efficiency, difficulty in guaranteeing accuracy, and poor adaptability. Traditional fixtures can only support clamping a single electrode, which is very inefficient. Manual positioning can easily lead to inconsistent electrode heights and poor product consistency. Furthermore, existing fixtures can only support grinding at a single angle. Changing to different angles requires new fixtures, which increases the complexity and cost of operation.

[0003] Therefore, there is an urgent need for a special fixture that supports batch clamping of multiple electrodes, can switch between multiple angles, and has controllable precision.

[0004] A search revealed a novel multi-angle mold electrode grinding and polishing fixture disclosed in Chinese patent literature [Application No.: 202220355889.5, Publication No.: CN216991421U], which includes a fixture base. A flip adjustment component is provided on one side of the bottom of the fixture base. Although this patent can achieve the purpose of batch processing and multi-angle processing, the structure is cumbersome, the cost is high, and the threshold for use is increased, which is not conducive to employees' quick learning and batch use. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an efficient electrode grinding clamping fixture.

[0006] A high-efficiency electrode grinding clamping fixture, characterized in that it comprises: a first base, a second base, and a tooling fixture; The tooling fixture can be selectively and detachably installed on the first base or the second base.

[0007] Preferably, one side of the tooling fixture is provided with a row of vertical clamping holes, the axis of which is perpendicular to the bottom surface of the tooling fixture; the other side of the tooling fixture is provided with a row of inclined clamping holes, the axis of which forms a preset angle with the bottom surface.

[0008] Through the above technical solution, the vertical clamping hole array on one side is suitable for clamping the workpiece in the forward direction, ensuring the verticality and stability during the clamping process; the inclined clamping hole array on the other side can meet the needs of quickly positioning and clamping electrodes that require inclined angle grinding, thus improving the applicability and flexibility of the tooling.

[0009] Specifically, this combination of vertical and inclined clamping hole arrays allows for flexible selection of vertical or inclined angles for clamping according to actual process requirements, thereby meeting the processing requirements of electrodes of different processes or specifications. The vertical clamping hole structure ensures efficient clamping and grinding of ordinary right-angle electrodes, while the inclined clamping hole array facilitates quick and easy fixing of electrodes requiring inclined surface grinding without additional adjustment of the fixture angle, greatly improving operating efficiency and processing accuracy.

[0010] Preferably, the clamping holes in both the vertical clamping hole row and the inclined clamping hole row are evenly distributed along the length direction of the tooling fixture.

[0011] The above technical solution, with its equally spaced clamping holes, facilitates precise positioning of each clamped electrode, avoiding positioning errors or clamping interference caused by inconsistent spacing, and further improving the precision and yield of product processing.

[0012] Specifically, by designing both the vertical and inclined clamping hole rows with equal spacing, users can easily perform batch clamping of multiple electrodes as needed, simplifying the process flow. At the same time, this equal-spacing arrangement effectively avoids misalignment or insecure clamping caused by irregular workpiece spacing, contributing to the realization of automated clamping and batch operation requirements on-site.

[0013] Preferably, both the vertical clamping hole row and the inclined clamping hole row are equipped with detachable screws.

[0014] Through the above technical solution, the detachable screws not only ensure the stability during clamping and prevent the workpiece from shifting during grinding, but also facilitate quick loosening and tightening when changing or adjusting the electrode, thus improving work efficiency.

[0015] Specifically, both the vertical and inclined clamping hole rows are equipped with removable screws, allowing operators to flexibly clamp and replace electrodes according to actual needs, reducing the impact of traditional clamping methods that are cumbersome and inefficient due to tool changes. At the same time, the removability of the screws facilitates routine maintenance and cleaning of the fixture, extending its service life.

[0016] Preferably, the tooling fixture has positioning grooves at the center of both the top and bottom.

[0017] The above technical solution provides positioning grooves at the top center and bottom center, which helps to accurately align the tooling fixture with the base when they are docked.

[0018] Specifically, the positioning grooves allow the fixture to quickly find the correct position when assembling with the base, improving clamping efficiency and ensuring consistency in clamping position each time. Whether changing fixtures or performing high-precision grinding operations, this significantly reduces errors caused by manual alignment. Furthermore, the double-sided positioning groove design further enhances the fixture's stability and reliability, preventing shaking or displacement during use and ensuring operational safety and processing stability.

[0019] Preferably, the tooling fixture has a through hole extending from the top to the bottom.

[0020] The through-hole design, which extends from the top to the bottom, allows fastening bolts and other connecting parts to pass through the tooling fixture and connect to the base, thus ensuring that the tooling fixture will not loosen or shift during operation and significantly improving the stability and safety of the clamping.

[0021] Specifically, the through-hole design simplifies the installation and disassembly of tooling fixtures and bases, facilitating quick tooling replacement and positioning, shortening setup time, and improving production efficiency. Simultaneously, it ensures reliable fixation, effectively preventing tooling fixture displacement due to vibration or other external forces during processing or clamping, thus ensuring stable processing accuracy and product quality.

[0022] Preferably, the top of the first base is provided with a positioning strip that matches the positioning groove; the first base is provided with a positioning hole corresponding to the position of the through hole.

[0023] Through the above technical solution, the top of the first base is provided with a positioning strip that is compatible with the positioning groove, which can closely cooperate with the positioning groove of the tooling fixture, thereby effectively restricting the lateral or rotational movement of the fixture, ensuring that the tooling fixture can be accurately aligned with the predetermined position each time it is clamped, and improving the clamping accuracy and the reliability of repeated positioning.

[0024] Meanwhile, the positioning hole on the first base corresponds to the through hole of the tooling fixture, allowing the fastening bolts or positioning pins to pass smoothly through the tooling fixture and insert into the first base, thus firmly fixing the tooling fixture to the base and preventing displacement or loosening during use. This simplifies installation and disassembly operations, improves work efficiency, and ensures safety and stability during processing.

[0025] Preferably, the top of the second base is provided with a mounting groove that matches the bottom of the tooling fixture; the mounting groove is provided with a positioning hole corresponding to the position of the through hole.

[0026] The above technical solution enables accurate installation and stable connection between the tooling fixture and the second base. The top of the second base is provided with a mounting groove that matches the shape of the bottom of the tooling fixture, allowing the tooling fixture to be accurately embedded in the mounting groove. This ensures that the tooling fixture can be quickly positioned during installation, preventing lateral or rotational deviation, thereby improving the consistency and repeatability of clamping.

[0027] Meanwhile, the mounting slot is provided with a second positioning hole corresponding to the position of the through hole of the tooling fixture, so that the fastening bolt or positioning pin can directly pass through the through hole of the tooling fixture and be inserted into the second positioning hole of the second base, thereby achieving reliable fixation between the tooling fixture and the base and further enhancing the stability during the installation process.

[0028] Compared with the prior art, the present invention has the following advantages: 1. This utility model, through the collaborative design of a split base and a universal tooling fixture, enables seamless switching between different grinding angles within the same clamping system. The operator only needs to install one tooling fixture onto the corresponding base to quickly switch between planar and inclined surface processing modes, eliminating the cumbersome steps of disassembling the entire clamp and readjusting the positioning required in traditional solutions. This modular structure retains the efficiency advantage of clamping multiple electrodes at once while also considering adaptability to complex angle scenarios.

[0029] 2. The double-sided clamping hole layout of the tooling fixture of this utility model realizes the synchronous fixing of multiple electrodes in a limited space, effectively avoiding the interruption and repeated positioning of traditional single-electrode processing operations. This design reduces the operator's reliance on precision calibration experience, making the processing quality easier to control, and is especially suitable for the continuous processing needs of multiple batches of electrodes.

[0032] Please see Figures 1 to 2 This utility model provides a technical solution: A high-efficiency electrode grinding clamping fixture, characterized in that it comprises: a first base (1), a second base (2), and a tooling fixture (3); The tooling fixture 3 can be selectively and detachably installed on the first base 1 or the second base 2.

[0033] Specifically, one side of the tooling fixture 3 is provided with a vertical clamping hole array, the axis of which is perpendicular to the bottom surface of the tooling fixture 3; the other side of the tooling fixture 3 is provided with an inclined clamping hole array, the axis of which forms a preset angle with the bottom surface.

[0034] Through the above technical solution, the vertical clamping hole array on one side is suitable for clamping the workpiece in the forward direction, ensuring the verticality and stability during the clamping process; the inclined clamping hole array on the other side can meet the needs of quickly positioning and clamping electrodes that require inclined angle grinding, thus improving the applicability and flexibility of the tooling.

[0035] Specifically, this combination of vertical and inclined clamping hole arrays allows for flexible selection of vertical or inclined angles for clamping according to actual process requirements, thereby meeting the processing requirements of electrodes of different processes or specifications. The vertical clamping hole structure ensures efficient clamping and grinding of ordinary right-angle electrodes, while the inclined clamping hole array facilitates quick and easy fixing of electrodes requiring inclined surface grinding without additional adjustment of the fixture angle, greatly improving operating efficiency and processing accuracy.

[0036] In practical applications, this multi-angle clamping hole design can significantly reduce workpiece changeover and adjustment time, improving production efficiency. It also enhances clamping reliability and consistency, reducing errors and product defect rates caused by manual adjustments. Therefore, this clamping fixture has significant practical value for the standardization, automation, and high-quality production of electrode grinding processes.

[0037] Specifically, the clamping holes in both the vertical clamping hole row and the inclined clamping hole row are evenly distributed along the length of the tooling fixture 3.

[0038] The above technical solution, with its equally spaced clamping holes, facilitates precise positioning of each clamped electrode, avoiding positioning errors or clamping interference caused by inconsistent spacing, and further improving the precision and yield of product processing.

[0039] Specifically, by designing both the vertical and inclined clamping hole rows with equal spacing, users can easily perform batch clamping of multiple electrodes as needed, simplifying the process flow. At the same time, this equal-spacing arrangement effectively avoids misalignment or insecure clamping caused by irregular workpiece spacing, contributing to the realization of automated clamping and batch operation requirements on-site.

[0040] In practical applications, the evenly spaced clamping hole arrangement improves the standardization of fixtures, facilitates rapid replacement and maintenance on the production line, reduces the risk of inconsistencies caused by manual adjustments, and improves overall processing efficiency. Therefore, this evenly spaced design plays a crucial role in ensuring high quality and high efficiency when batch processing electrodes, and has significant practical value and promotion potential.

[0041] Specifically, both the vertical clamping hole row and the inclined clamping hole row are equipped with detachable screws 4.

[0042] Through the above technical solution, the detachable screw 4 not only ensures the stability during the clamping process and prevents the workpiece from shifting during the grinding process, but also facilitates quick loosening and tightening when changing or adjusting the electrode, thus improving work efficiency.

[0043] Specifically, both the vertical and inclined clamping hole rows are equipped with removable screws 4, allowing operators to flexibly clamp and replace electrodes according to actual needs, reducing the impact of traditional clamping methods that are cumbersome and inefficient due to tool changes. At the same time, the removability of the screws 4 also facilitates routine maintenance and cleaning of the fixture 3, extending its service life.

[0044] In practical applications, this design is not only suitable for clamping electrodes of different sizes or shapes, but also meets the requirements for switching between multiple batches and types of electrodes, effectively improving the flexibility and batch operation capability of the production line. Therefore, the clamping method using detachable screws 4 helps to ensure the stability and efficiency of the electrode grinding process, and has significant practical application value.

[0045] Specifically, positioning grooves 31 are provided at the center of the top and the center of the bottom of the tooling fixture 3.

[0046] The above technical solution provides positioning grooves 31 at the top center and bottom center, which helps to accurately align the tooling fixture 3 with the base when they are docked.

[0047] Specifically, the positioning groove 31 allows the fixture 3 to quickly find the correct position when assembling with the base, improving clamping efficiency and ensuring consistency in clamping position each time. Whether changing fixtures or performing high-precision grinding operations, it significantly reduces errors caused by manual alignment. At the same time, the design of the double-sided positioning groove 31 further enhances the stability and reliability of the fixture 3, preventing shaking or displacement during use and ensuring operational safety and processing stability.

[0048] In practical applications, this positioning groove 31 structure simplifies the clamping process, facilitates quick installation and replacement of fixture 3, increases production cycle time, reduces the difficulty of alignment operations for workers, and effectively improves processing efficiency and product quality. Therefore, the design of this positioning groove 31 plays an important role in improving the overall accuracy and ease of operation of the electrode grinding clamping device.

[0049] Specifically, the tooling fixture 3 has a through hole 32 extending from the top to the bottom.

[0050] Through the above technical solution, the through hole 32, which runs from top to bottom, allows fastening bolts and other connecting parts to pass through the tooling fixture 3 and connect to the base, thereby ensuring that the tooling fixture 3 will not loosen or shift during operation, and significantly improving the stability and safety of the clamping.

[0051] Specifically, the through hole 32 simplifies the installation and disassembly of the tooling fixture 3 and the base, facilitating quick tooling replacement and positioning, shortening setup time, and improving production efficiency. Simultaneously, it ensures reliable fixation, effectively preventing displacement of the tooling fixture 3 due to vibration or other external forces during processing or clamping, thus ensuring stable processing accuracy and product quality.

[0052] Therefore, by setting a through hole 32 that runs from top to bottom, the safety and reliability of the connection between the tooling fixture 3 and the base are improved, which has important practical application value.

[0053] Specifically, the top of the first base 1 is provided with a positioning strip 11 that is adapted to the positioning groove 31; the first base 1 is provided with a positioning hole 12 corresponding to the position of the through hole 32.

[0054] Through the above technical solution, the top of the first base 1 is provided with a positioning strip 11 that is adapted to the positioning groove 31, which can closely cooperate with the positioning groove 31 of the tooling fixture 3, thereby effectively restricting the lateral or rotational movement of the fixture 3, ensuring that the tooling fixture 3 can be accurately aligned with the predetermined position each time it is clamped, and improving the clamping accuracy and the reliability of repeated positioning.

[0055] Meanwhile, the positioning hole 12 on the first base 1 corresponds to the through hole 32 of the tooling fixture 3, allowing the fastening bolts or positioning pins to pass smoothly through the tooling fixture 3 and be inserted into the first base 1, thus achieving a firm fixation between the tooling fixture 3 and the first base 1 and preventing displacement or loosening during use. This simplifies installation and disassembly operations, improves work efficiency, and ensures safety and stability during processing.

[0056] In summary, the cooperation between the positioning strip 11 and the positioning groove 31, and the cooperation between the positioning hole 12 and the through hole 32, not only improves the installation convenience and positioning accuracy of the tooling fixture 3 and the first base 1, but also significantly enhances the stability and reliability of the overall connection.

[0057] Specifically, the top of the second base 2 is provided with an installation groove 21 that matches the bottom of the tooling fixture 3; the installation groove 21 is provided with a positioning hole 22 that corresponds to the position of the through hole 32.

[0058] The above technical solution enables accurate installation and stable connection between the tooling fixture 3 and the second base 2. The top of the second base 2 is provided with a mounting groove 21 that matches the shape of the bottom of the tooling fixture 3, so that the tooling fixture 3 can be accurately embedded in the mounting groove 21, ensuring that the tooling fixture 3 can be quickly positioned during installation, preventing lateral or rotational deviation, thereby improving the consistency and repeatability of clamping.

[0059] Meanwhile, the mounting groove 21 is provided with a positioning hole 22 corresponding to the position of the through hole 32 of the tooling fixture 3, so that the fastening bolt or positioning pin can directly pass through the through hole 32 of the tooling fixture 3 and be inserted into the positioning hole 22 of the second base 2, thereby achieving reliable fixation between the tooling fixture 3 and the second base 2 and further enhancing the stability during the installation process.

[0060] In summary, by matching the mounting slot 21 with the bottom of the tooling fixture 3, and by matching the positioning hole 22 with the through hole 32, the tooling fixture 3 can be easily installed, accurately positioned, and securely connected on the second base 2, effectively improving the overall performance of the tooling system and the efficiency of production operations.

[0061] In practical use, when it is necessary to grind the electrode angle surface at 0°, the electrode can be installed on the vertical clamping hole row of the tooling fixture 3, and the tooling fixture 3 is installed on the first base 1. When it is necessary to grind the electrode angle surface at 15°, the electrode can be installed on the inclined clamping hole row of the tooling fixture 3, and the tooling fixture 3 is installed on the first base 1. When it is necessary to grind the electrode angle surface at 45°, the electrode can be installed on the vertical clamping hole row of the tooling fixture 3, and the tooling fixture 3 is installed on the second base 2. This achieves the purpose of multi-angle processing.
