[0036] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] (like Figure 1 (As shown) A clamping device for a combined turnout rail includes a base worktable 1, a magnetic suction device 2, a positioning base 3, a positioning device 4, and a controller.

[0038] The magnetic chuck 2 consists of a strip-shaped structure composed of one or more electromagnetic chucks. The strip structure is planar, facilitating the flat placement of the workpiece. The electromagnetic chucks possess strong suction force, exceeding 16 kg / cm², meeting the needs of various high-intensity machining, roughing, and finishing processes. The uniform magnetic force distribution ensures the stability of the attracted workpiece during processing, improving machining accuracy. The electromagnetic chuck's suction force does not require continuous power supply, eliminating the risk of demagnetization. Continuous operation does not generate heat, thus preventing workpiece deformation due to heat and ensuring machining accuracy. The strip-shaped structure composed of one or more electromagnetic chucks can be flexibly configured according to actual needs, suitable for workpieces of different shapes and sizes.

[0039] The positioning bases 3 are symmetrically distributed on both sides of the magnetic attraction device 2. The symmetric distribution of the positioning bases on both sides of the magnetic attraction device can provide balanced support force for the magnetic attraction device, ensuring its stability during operation and reducing the likelihood of shaking or tilting. This layout helps to reduce the impact of external forces or vibrations generated during processing on the magnetic attraction device and the attracted workpiece, thereby improving processing accuracy and stability. The design of the positioning bases usually includes precise calibration and positioning mechanisms, which can ensure accurate alignment between the magnetic attraction device and the workpiece being processed, reducing processing errors caused by positional deviations. The symmetrically distributed bases can maintain consistency within the working area of the magnetic attraction device, ensuring that workpieces at different positions can achieve the same processing accuracy and surface quality. The symmetrically distributed bases help to reduce safety risks caused by equipment instability or workpiece falling off.

[0040] The positioning devices 4 are installed on both sides of the positioning bases 3; the positioning devices 4 on both sides form V-shaped positioning surfaces consistent with the slope of the workpiece to be processed; the V-shaped positioning surfaces wedge into the clamping of the workpiece to be processed; the positioning devices 4 quickly align and position the workpiece to be processed by clamping and positioning the two side surfaces of the workpiece to be processed and longitudinally wedging.

[0041] It should be noted that the V-shaped positioning surface can match the slope of the workpiece to be processed, achieving automatic centering effect. This means that when the workpiece is placed on the V-shaped positioning surface, it can be automatically adjusted to a relatively accurate position, reducing the time and error of manual alignment. The positioning device 4 not only matches the slope through the V-shaped positioning surface, but also clamps and positions the two side surfaces of the workpiece to be processed. This double positioning method ensures the stability of the workpiece in multiple directions and improves the accuracy of positioning. Under the joint action of the V-shaped positioning surface and the clamping and positioning of the two side surfaces, the freedom of the workpiece in multiple directions is limited, so that the workpiece remains stable during processing. This helps to reduce processing errors caused by workpiece movement or vibration and improve processing accuracy. Since the design of the V-shaped positioning surface is consistent, the same positioning effect and processing accuracy can be guaranteed regardless of the slope of the workpiece being processed. This helps to achieve consistency in batch production and processing. The wedge clamping method allows the workpiece to be quickly and accurately positioned on the V-shaped positioning surface, reducing clamping time and manual operation complexity. This helps to improve production efficiency and shorten the production cycle. Through the simple V-shaped positioning surface and clamping and positioning of the two side surfaces, complex positioning functions are achieved, thereby simplifying the overall structure of the equipment. This helps to reduce production costs and manufacturing difficulty. Since the equipment structure is simple and easy to operate, maintenance and maintenance work is also relatively simple.

[0042] After the workpiece to be processed is positioned on the V-shaped positioning surface of the positioning device 4, the controller controls the magnetic attraction device 2 to magnetically attract the workpiece to be processed, completing workpiece clamping; the controller controls the magnetic attraction device 2 to demagnetize, achieving workpiece unloading.

[0043] It should be noted that when the workpiece is positioned on the V-shaped positioning surface, the controller quickly controls the magnetizing device 2 to magnetize, and the strong magnetic force can quickly and firmly attract the workpiece to the magnetizing device, completing the clamping process. This process is usually very fast, which can significantly improve production efficiency. After processing is completed, the controller controls the magnetizing device 2 to demagnetize, and the magnetic force disappears, so that the workpiece can be easily unloaded from the magnetizing device. This unloading method is also fast and convenient, reducing the time and labor intensity of manual operation. Because the magnetizing device can firmly attract the workpiece, it reduces the movement or deviation of the workpiece due to vibration during processing, thereby improving the processing precision. During the entire processing process, the workpiece is kept in precise positioning on the magnetizing device, avoiding processing errors caused by workpiece movement. Compared with traditional mechanical clamps, the magnetizing device does not produce mechanical wear during clamping, thereby reducing the replacement frequency and maintenance cost of the clamp. The magnetizing device does not need continuous power supply to maintain the adsorption force during work, and only needs to consume power during magnetization and demagnetization, so it has the characteristics of energy saving and high efficiency. The magnetizing device can attract a variety of metal materials, including iron, cobalt, nickel and their alloys, etc., so it is suitable for processing of various workpieces. The design of the V-shaped positioning surface makes the magnetizing device adapt to workpieces of different shapes and sizes, improving the flexibility and adaptability of the equipment. The magnetizing device can be integrated with controllers, sensors and other automated equipment to realize automatic clamping, processing and unloading of workpieces, improving the automation level of the production line. Through programming and setting, the controller can automatically adjust the magnetization and demagnetization time, strength and other parameters of the magnetizing device according to different processing requirements and workpiece characteristics, realizing intelligent control.

[0044] (As Figure 2 , Figure 3 , Figure 5 , Figure 6In the above embodiments, as a further improved embodiment of the utility model: the bottom surface of the magnetic attraction device 2 is provided with an interface connected and fixed with the base workbench 1. The base workbench 1 has a T-shaped positioning groove. The interface design of the magnetic attraction device 2 ensures that the magnetic attraction device 2 can be accurately and firmly fixed on the base workbench 1, preventing displacement or loosening during processing due to vibration or external force, thereby ensuring the stability and reliability of processing. Stable connection reduces the processing error caused by equipment movement, improves the processing precision of the workpiece. The standardized interface design makes the installation and disassembly of the magnetic attraction device 2 simple and fast, reduces the time required for replacing workpieces or adjusting equipment, and improves production efficiency. The interface design usually has certain compatibility and can adapt to different models and specifications of magnetic attraction devices, facilitating flexible configuration and replacement according to processing needs. The interface design usually takes into account the needs of different working environments and processing conditions, so that the magnetic attraction device can be applied to various base workbenches, improving the adaptability and flexibility of the equipment. Stable connection reduces the risk of accidental falling of the magnetic attraction device during processing, ensuring the safety of operators and equipment.

[0045] In the above embodiments, as a further improved embodiment of the utility model: (as shown in Figure 4 、 Figure 6 It also includes an auxiliary device 5; the auxiliary device 5 is symmetrically distributed on both sides of the magnetic attraction device 2, and the auxiliary device 5 clamps the rear end of the workpiece. The magnetic attraction device 2 attracts the front end or main part of the workpiece by magnetic force, and the auxiliary device 5 clamps the rear end of the workpiece. This double clamping mechanism ensures the stability of the workpiece during processing, reducing the movement or deviation of the workpiece due to vibration or external force. The clamping action of the auxiliary device 5 increases the contact area between the workpiece and the processing platform, thereby improving the rigidity of the workpiece. This helps to reduce deformation during processing and improve processing accuracy.

[0046] In the above embodiments, as a preferred embodiment of the utility model: (as shown in Figure 6 The auxiliary device 5 is composed of an auxiliary support block 5-1, an auxiliary support block mounting bolt 5-2 and an auxiliary support side jacking bolt 5-3; the auxiliary support block 5-1 is composed of a first auxiliary support block and a second auxiliary support block; the first auxiliary support block is a square structure in longitudinal section; the first auxiliary support block is the same height as the magnetic attraction device 2; the second auxiliary support block is fastened to the first auxiliary support block as a whole by using the vertical auxiliary support block mounting bolt 5-2; the second auxiliary support block is a right triangle structure in longitudinal section, the inner vertical positioning surface of the second auxiliary support block is provided with a horizontally arranged auxiliary support side jacking bolt 5-3, and the auxiliary support side jacking bolt 5-3 jacks up the vertical side of the workpiece.

[0047] It needs to be explained that: the auxiliary device 5 can realize accurate clamping of the rear end of the workpiece through the combination of the first auxiliary support block and the second auxiliary support block, and the tightening action of the auxiliary support side tightening bolt 5-3. This clamping method ensures the position accuracy of the workpiece during processing, reduces the processing errors caused by the movement or deviation of the workpiece. The first auxiliary support block is the same height as the magnetic attraction device 2, which provides stable horizontal support for the workpiece; while the right triangle structure of the second auxiliary support block further enhances the vertical support of the workpiece. This double support mechanism ensures the stability of the workpiece during processing, preventing the workpiece from shaking due to vibration or external force. The right triangle structure design of the second auxiliary support block is flexible and can adapt to different shapes and sizes of the rear end of the workpiece. This makes the auxiliary device 5 widely applicable to the processing of various workpieces, improving the adaptability and flexibility of the equipment. By adjusting the tightening force and position of the auxiliary support side tightening bolt 5-3, accurate clamping and positioning of the rear end of different workpieces can be achieved. This adjustability allows the auxiliary device 5 to meet different processing needs, improving processing efficiency and quality. The modular design of the auxiliary device 5 makes the clamping process simple and fast. The operator only needs to place the workpiece on the first auxiliary support block, and then tighten it through the auxiliary support block mounting bolt 5-2 and the auxiliary support side tightening bolt 5-3. This quick clamping method reduces the time required for manual adjustment of the workpiece position, improving production efficiency. The stable clamping mechanism effectively prevents the risk of workpiece falling during processing, ensuring the safety of operators and equipment. The auxiliary device 5 adopts modular design, and each component is relatively independent and easy to disassemble. This makes maintenance and repair work simple and convenient, reducing maintenance cost and difficulty. The auxiliary support block mounting bolt 5-2 and the auxiliary support side tightening bolt 5-3 and other components adopt standardized interface design, which is convenient for replacement and upgrading. At the same time, it also improves the reliability and durability of the equipment.

[0048] In the above embodiment, as a further improved embodiment of the present application: the positioning base 3 and the magnetic attraction device 2 are of an integrated structure or a split structure.

[0049] (As shown in Figure 1 , Figure 2 When the positioning base 3 and the magnetic attraction device 2 are of an integrated structure: the positioning base 3 is provided with a positioning block notch; the positioning block notch is used for positioning and clamping of different types of center rail positioning devices 4; the positioning surface of the positioning device 4 is used for positioning and clamping of different types of workpieces.

[0050] The integrated structure tightly combines the positioning base 3 and the magnetic suction device 2, reducing gaps and connectors between components and resulting in a more compact overall structure. This compact structure helps reduce the space occupied by the equipment and improves the layout flexibility of the production line. Since the positioning base 3 and the magnetic suction device 2 are integrally cast or machined, their connection is very strong, providing better rigid support. This rigid support helps reduce vibration and deformation during processing, improving the machining accuracy and stability of the workpiece. The integrated structure simplifies the equipment installation process, reducing installation steps and time. At the same time, the fewer connections between components also reduce maintenance complexity and costs.

[0051] (like Figure 4 , Figure 5 (As shown) When the positioning base 3 and the magnetic suction device 2 are separate structures: the positioning base 3 can move and be fixed along the length direction of the magnetic suction device 2. The positioning base 3 has a concave structure, which is adapted to the convex structure of the positioning device 4. The positioning surface of the positioning device 4 is used for positioning and clamping of workpieces of different models.

[0052] It's important to note that the split-type structure allows the positioning base 3 and the magnetic suction device 2 to be designed and manufactured separately, and then assembled as needed. This design offers greater flexibility, allowing for the selection of appropriate positioning bases and magnetic suction devices based on different processing requirements and workpiece characteristics. In the split-type structure, if the positioning base or magnetic suction device is damaged or requires upgrading, it can be replaced or upgraded individually without replacing the entire device. This design reduces equipment maintenance costs and upgrade complexity. The split-type structure better adapts to the needs of different working environments and processing conditions. For example, in situations requiring frequent workpiece changes or adjustments to processing parameters, the split-type structure allows for faster equipment adjustment and reconfiguration.

[0053] Overall Comparison: If production line space is limited, an integrated structure may be more advantageous because it reduces the space occupied by the equipment. For applications requiring high-precision machining, an integrated structure may be more suitable because it provides better rigidity support. If the production line requires frequent workpiece changes or adjustments to machining parameters, a modular structure may be more advantageous because it offers greater flexibility and adaptability.

[0054] In the above embodiments, as an application embodiment of the present utility model: the workpiece is a heart rail workpiece that can realize magnetic attraction function. The heart rail workpiece should select materials with good magnetic permeability and magnetic holding force, such as hard ferrite, rare earth permanent magnetic materials, etc. These materials can ensure that the heart rail workpiece generates stable adsorption force under the action of the magnetic field. Since the heart rail workpiece has the magnetic attraction function, it can be accurately adsorbed on the magnetic attraction device, thereby realizing high-precision positioning. This is particularly important for machining processes that require precise control of workpiece position.

[0055] In the above embodiments, as a preferred embodiment of the present utility model: the positioning devices 4 are all quick-change positioning block structures. The quick-change positioning block structure enables different positioning blocks to be quickly replaced to adapt to different workpieces or production needs during the production process. This greatly reduces the downtime caused by replacing the positioning devices, thereby improving the overall production efficiency. Since the positioning blocks can be quickly replaced, the adjustment time required for replacing the positioning devices, including mechanical adjustment, calibration, etc., is reduced, further improving the production efficiency. The quick-change positioning block structure can easily adapt to workpieces of different shapes, sizes and weights, meeting the needs of diversified production. This makes the production line more flexible and can quickly respond to market changes and customer customization needs. By adopting the quick-change positioning block, the design complexity of the clamp can be simplified, and the manufacturing cost and maintenance difficulty of the clamp can be reduced. At the same time, due to the standardized and modular design of the positioning block, inventory management and replacement are also facilitated. The quick-change positioning block usually has high positioning accuracy and repeatability, which can ensure accurate positioning of the workpiece during the machining process. This helps to improve machining precision and product quality. Due to the quick replacement and accurate positioning capability of the positioning block, errors and scrap rates caused by manual adjustment or inaccurate positioning can be reduced. The quick-change positioning block structure helps to reduce the number of clamps manufactured and the maintenance cost, thereby saving production resources. At the same time, due to the standardized and modular design of the positioning block, resource sharing and reuse are also facilitated. Due to the quick replacement feature of the positioning block, maintenance work becomes simple and fast. When the positioning block fails or wears out, it can be quickly replaced without the need for major repairs of the entire clamp. The standardized and modular design of the positioning block makes inventory management easier. Enterprises can stock an appropriate amount of positioning blocks in advance according to production needs to avoid affecting production progress due to lack of stock.

[0056] In the above embodiments, as a further improved embodiment of the present utility model: the controller is provided with a magnetizing button and a demagnetizing button. The magnetizing button and the demagnetizing button enable the operator to directly perform magnetizing and demagnetizing operations on the controller without complex settings or adjustments, improving work efficiency. The magnetizing button and the demagnetizing button make the functions of the controller more explicit, and the operator can clearly know the functions of each button, reducing the possibility of misoperation.

[0057] In the above embodiment, as a further improved embodiment of the utility model: still include degaussing instrument, degaussing instrument is to work piece demagnetization processing, is used for eliminating work piece residual magnetism, does not influence work piece's use.

[0058] The utility model relates to a kind of processing methods of combined frog rail heart, using any described clamping device processes the combined frog rail heart, and include following steps:

[0059] S1, preparation work: according to the corresponding positioning device 4 selected for the workpiece to be processed, and the positioning device 4 is positioned and installed on the positioning base 3. By preparing and installing the positioning device suitable for the workpiece to be processed in advance, the production preparation time can be shortened, so that the production line can be quickly put into production state. This reduces the downtime caused by frequent replacement and adjustment of positioning device, improves the overall production efficiency. Selecting the positioning device matched with the workpiece to be processed can ensure accurate positioning and support of the workpiece during machining. This helps to reduce machining errors caused by inaccurate positioning, improves machining accuracy and product quality. Different workpieces require different positioning methods and support structures. By selecting and installing the corresponding positioning device, the production line can flexibly meet the diversified production needs and quickly adapt to the machining requirements of different workpieces.

[0060] S2, quickly aligning positioning: the workpiece to be processed is hoisted and placed between the two positioning devices 4; by knocking down, the workpiece is clamped and aligned between the two positioning devices 4; by knocking along the horizontal longitudinal direction, the workpiece is wedged and aligned between the positioning devices 4.

[0061] It should be noted that by knocking the workpiece downward, it can be aligned between the two positioning devices, ensuring accurate positioning of the workpiece in the horizontal direction. This physical contact alignment method is more reliable than simple mechanical positioning, reducing positioning errors caused by irregular shapes or uneven surfaces of the workpiece. Knocking the workpiece along the horizontal longitudinal direction and wedging it between the positioning devices can further fine-tune the position of the workpiece, ensuring accurate positioning in all critical dimensions. This fine-tuning capability is crucial for improving machining accuracy. The quick alignment positioning method is based on physical knocking principles, intuitive and easy to operate. Operators only need to complete the workpiece alignment work through simple knocking actions, without complex measurement and calculation processes. Compared with using precision measuring tools for alignment, the quick alignment positioning method reduces dependence on measuring tools. This reduces the skill level required for operators and reduces errors caused by tool damage or inaccurate calibration. The quick alignment positioning method is suitable for workpieces of various shapes and sizes. Whether it is a regular-shaped workpiece or a complex-shaped workpiece, accurate positioning can be achieved through appropriate knocking and fine-tuning. In the machining process, if the workpiece position deviates or needs to be adjusted, it can be quickly restored to the correct position by knocking and fine-tuning again. This flexibility enables production lines to respond to various unexpected situations and changing needs.

[0062] S3, adsorption: press the magnetizing button of the controller, the magnetic attraction device 2 is magnetized, and the magnetic attraction device 2 firmly adsorbs the workpiece. By pressing the magnetizing button of the controller, the magnetic attraction device 2 can quickly magnetize and generate strong adsorption force. This instant response capability ensures that the workpiece is firmly adsorbed on the magnetic attraction device in a very short time, improving production efficiency and safety. The magnetized magnetic attraction device can continuously provide stable adsorption force, maintaining the stable position of the workpiece even in a vibrating or impacting environment, reducing machining errors and safety hazards caused by workpiece movement or deviation. The magnetizing process only needs to press the magnetizing button of the controller, which is simple and fast. This reduces the skill requirements and work burden of operators, making it easier for operators on the production line to master and use this technology. Combined with an automatic control system, the automatic magnetizing and demagnetizing processes of the magnetic attraction device can be realized. This further improves the automation and intelligence level of the production line, reducing the possibility of manual intervention and incorrect operation. The magnetic attraction device can adapt to workpieces of different shapes, sizes and weights. By adjusting the magnetic field strength and layout of the magnetic attraction device, accurate adsorption and positioning of different workpieces can be achieved. The magnetic attraction device can ensure accurate positioning of the workpiece during machining. Through strong adsorption force and stable adsorption effect, machining errors and scrap rates caused by workpiece movement or deviation can be reduced. Since the workpiece is firmly adsorbed on the magnetic attraction device, frequent adjustment of the workpiece position or additional fixing operations during machining are not required. This helps to improve machining efficiency and reduce production costs.

[0063] S4, processing: Once the processing program is set, the machine tool can automatically complete the processing of the workpiece according to the process requirements without manual intervention or frequent adjustment. This greatly improves production efficiency and capacity.

[0064] S5, unloading workpiece: After the workpiece is processed, press the demagnetization button of the controller, and the magnetic force of the magnetic attraction device 2 is eliminated, which is convenient for unloading the workpiece. By simply pressing the demagnetization button of the controller, the magnetic force of the magnetic attraction device can be quickly eliminated. This one-key operation not only simplifies the work process, but also improves the production efficiency. The demagnetization process is rapid, and the elimination of magnetic force is almost instantaneous, so that the workpiece can be quickly separated from the magnetic attraction device, which is convenient for subsequent handling and other processes. The magnetic force is eliminated in time after processing, which can avoid accidental injuries such as finger injury or workpiece falling caused by magnetic force when workers handle the workpiece. After demagnetization, there is no magnetic force between the workpiece and the magnetic attraction device, which reduces the damage to the surface of the workpiece caused by friction or collision.

[0065] S6, eliminating residual magnetism of workpiece: using demagnetizing instrument to demagnetize the workpiece, eliminating residual magnetism of workpiece without affecting the use of workpiece. Demagnetization treatment can ensure that the workpiece does not have residual magnetism during processing or use by using professional demagnetizing instrument. Eliminate residual magnetism of workpiece to avoid affecting railway locomotive and line signal during product use and eliminate safety hazards.

[0066] In the above embodiment: before the workpiece is subjected to large cutting amount milling processing, a certain number of auxiliary devices 5 are added to the corresponding parts of the workpiece according to the size of the processing parts and the cutting amount, so as to ensure the stability and processing precision of the workpiece, and then the workpiece is processed. The technical effect of the auxiliary device 5 is the same as before, which will not be repeated here.

[0067] In the above embodiment: each machine tool is provided with multiple clamping devices corresponding to multiple workpieces. Through the use of clamping devices, labor intensity is reduced, processing auxiliary time is effectively reduced, processing speed is further accelerated, and processing cycle is shortened. When multiple workpieces are positioned and clamped by using multiple workpiece clamping devices, the position accuracy of the workpiece is determined by the clamp, which is not affected by the technical level of workers. This makes the processing quality of the same batch of parts tend to the same level, improves the processing precision and stability, and simplifies the clamping process. The dependence on the technical proficiency of workers is reduced, so that workers with lower technical level can also perform the operation task, thereby reducing labor costs. By matching multiple clamping devices, the machine tool can process workpieces of different types and shapes, thereby expanding the use range of the machine tool. This makes the same machine tool can complete more processing tasks, and improves the utilization rate of the machine tool.

[0068] It can be found through the above description that the tool positioning device 4 adopts a quick replaceable positioning block structure, and through making different inclination replaceable positioning blocks, the use of various workpieces can be met, and the application range of the tool is improved.

[0069] The tool positioning device 4 adopts a quick replaceable positioning block structure, and through making different inclination replaceable positioning blocks, the use of various workpieces can be met, and the application range of the tool is improved.

[0070] The tool changes the traditional machining positioning and clamping mode, and combines the workpiece material characteristics to clamp the workpiece in the mode of electromagnetic adsorption, so that the use amount of traditional bolts and pressing plates is greatly reduced, the mounting and dismounting time is reduced, quick and accurate positioning and clamping are realized, and the labor intensity is reduced.
