Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment of cutting tools, specifically a quick loading and unloading fixture for heat treatment of mechanical cutting tools. Background Technology

[0002] In the production of machine tools, heat treatment is a crucial process. Its purpose is to change the microstructure of the tool by heating, holding, and cooling it, thereby improving its hardness, strength, toughness, and other properties, and extending its service life.

[0003] During heat treatment, clamps are needed to fix the cutting tools. A search revealed a utility model patent in China with publication number CN209619389U, which discloses a quenching clamp for cemented carbide cutting tools, including a connecting plate. This quenching clamp for cemented carbide cutting tools, by setting multiple components, can quench multiple tools simultaneously, significantly improving the quenching efficiency. Furthermore, by setting components such as push rods, it solves the problem of tools easily sticking slightly to the clamp after quenching. Tool-clamp separation is quick and simple, saving manpower. Although the above technical solution achieves rapid tool loading and unloading, the existing technology still has some shortcomings. The device lacks a corresponding adjustment and fixing structure during use, and can only fix tools of a single size, making it impossible to fix tools of different sizes, reducing practicality. Therefore, a quick-loading and unloading clamp for mechanical tool heat treatment is needed to solve the aforementioned problems. Utility Model Content

Both ends of the two sets of the first sliding rods are connected to the inner ends of the two sets of the first fixed plates. The two sets of sliding plates are slidably connected to the two sets of the first sliding rods. The adjusting mechanism is connected to the side of the moving block away from the movable clamping plate. The second fixed plate is connected to the top of the mounting platform.

[0008] The pushing mechanism includes a mounting plate, an electric cylinder, and two sets of slide rails. Both sets of slide rails are connected to the top of the base plate. The bottom of the mounting platform is slidably connected to the two sets of slide rails. The mounting plate is connected to the top of the base plate. The electric cylinder is connected to one side of the mounting plate, and the output end of the electric cylinder is connected to one side of the mounting platform.

[0009] The adjustment mechanism includes an adjustment screw, which is threadedly connected to the side of the moving block away from the movable clamping plate, and the tangential surface of the turntable is in contact with the adjustment screw.

[0010] Each of the two sets of first slide rods is fitted with two sets of second springs.

[0013] The turntable is provided with a handle on the side away from the second fixed plate, and the handle is away from the center area of ​​the turntable.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

Simultaneously, the first spring and movable rod provide appropriate cushioning during clamping, ensuring a secure hold. This makes tool loading and unloading convenient and efficient, saving labor and time costs, continuing and further optimizing the advantages of rapid loading and unloading in existing technologies.

[0017] Furthermore, it enhances the convenience and safety of heat treatment operations. Through the coordination of the pushing mechanism with the mounting platform and clamping mechanism, the pushing mechanism can smoothly move the clamping mechanism and the tool body on the mounting platform, achieving automated or semi-automated operation of the tool entering and exiting the heating furnace. This eliminates the need for manual handling of tools in and out of the high-temperature heating furnace, reducing direct contact between operators and the high-temperature environment, lowering operational risks, and also improving the continuity and efficiency of the heat treatment process.

[0018] Finally, the overall structure is reasonably designed and highly stable. The sliding cooperation between the two sets of sliding plates and the two sets of first sliding rods in the clamping mechanism provides stable guidance for the movement of the moving block and the movable clamping plate, ensuring the precise position of the tool during clamping and preventing the tool from shifting or falling off during heat treatment due to unstable clamping, thus guaranteeing the quality of heat treatment.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] Please see Figures 1-5 A quick-loading and unloading fixture for heat treatment of mechanical cutting tools includes a base plate 1, a heating furnace body 2, and a cutting tool body 3. The heating furnace body 2 is mounted on the top of the base plate 1 and is used to heat the cutting tool body 3. The fixture also includes:

[0027] The push mechanism, mounting platform 4, and clamping mechanism are provided. The push mechanism is mounted on the top of the base plate 1, the mounting platform 4 is mounted on the push mechanism, and the clamping mechanism is mounted on the mounting platform 4. The clamping mechanism can quickly fix different types of tool bodies 3. The push mechanism pushes the mounting platform 4 to move, so that the tool body 3 enters and exits the heating furnace body 2, thereby realizing the heat treatment of the tool body 3.

[0028] The clamping mechanism includes a fixed clamping plate 5, a movable clamping plate 6, a movable rod 7, a first spring 8, a connecting block 9, a moving block 10, two sets of sliding plates 11, two sets of first sliding rods 12, two sets of first fixed plates 13, an adjusting mechanism, a turntable 14, a connecting shaft 15, and a second fixed plate 16. The fixed clamping plate 5 is connected to one side of the top of the mounting platform 4. The outer end of the tool body 3 is in close contact with the inner end of the fixed clamping plate 5 and the movable clamping plate 6. The connecting block 9 has a groove 17 on the side near the movable clamping plate 6. The outer wall of the movable rod 7 is slidably connected to the groove 17. The first spring 8 is located in the groove 17, and both ends of the first spring 8 are connected to the movable rod 7 and the groove 17, respectively. The moving block 10 is connected to the connecting block 9 on the side near the movable clamping plate 6. Next, the top ends of the two sets of sliding plates 11 are connected to the bottom end of the moving block 10, the two sets of first fixed plates 13 are connected to the top end of the mounting platform 4, the two ends of the two sets of first sliding rods 12 are connected to the inner ends of the two sets of first fixed plates 13, the two sets of sliding plates 11 are slidably connected to the two sets of first sliding rods 12, the adjustment mechanism is connected to the side of the moving block 10 away from the movable clamping plate 6, the second fixed plate 16 is connected to the top end of the mounting platform 4, one end of the connecting shaft 15 is rotatably connected to the second fixed plate 16, the other end of the connecting shaft 15 is connected to one end of the turntable 14, and the connecting shaft 15 is away from the center of the turntable 14. The turntable 14 has a cut surface 18 on its outer periphery, and the outer periphery of the turntable 14 is slidably attached to the adjustment mechanism, and the cut surface 18 is slidably attached to the adjustment mechanism.

[0029] First, it effectively solves the problem that existing fixtures cannot adapt to tools of different sizes. By setting up a fixture mechanism composed of a fixed clamping plate 5, a movable clamping plate 6, a movable rod 7, a first spring 8, a connecting block 9, a moving block 10, a sliding plate 11, a first sliding rod 12, a first fixed plate 13, an adjusting mechanism, a turntable 14, a connecting shaft 15, and a second fixed plate 16, it can quickly and stably fix tool bodies 3 of different types and sizes. Compared with existing technologies that can only fix tools of a single size, the fixture mechanism of this utility model has flexible adjustment capabilities, significantly improving the versatility and practicality of the fixture and expanding its application range.

[0030] Secondly, it enables rapid tool loading and unloading. With the cooperation of the adjusting mechanism, turntable 14, and connecting shaft 15, the operator only needs to rotate the turntable 14 to drive the adjusting mechanism via the connecting shaft 15, which in turn moves the moving block 10, movable clamping plate 6, and other components to clamp or release the tool. Simultaneously, the first spring 8 and movable rod 7 provide appropriate cushioning during clamping, ensuring a secure hold. This makes the tool loading and unloading process convenient and efficient, saving manpower and time costs, continuing and further optimizing the advantages of rapid loading and unloading in existing technologies.

[0031] Furthermore, it enhances the convenience and safety of heat treatment operations. Through the coordination of the pushing mechanism with the mounting platform 4 and the clamping mechanism, the pushing mechanism can smoothly move the clamping mechanism and the tool body 3 on the mounting platform 4, achieving automated or semi-automated operation of the tool entering and exiting the heating furnace body 2. This eliminates the need for manual handling of the tool in and out of the high-temperature heating furnace, reducing direct contact between operators and the high-temperature environment, lowering operational risks, and also improving the continuity and efficiency of the heat treatment process.

[0032] Finally, the overall structure is reasonably designed and highly stable. The sliding engagement of the two sets of sliding plates 11 and the two sets of first sliding rods 12 in the clamping mechanism provides stable guidance for the movement of the moving block 10 and the movable clamping plate 6, ensuring the precise position of the tool during clamping and preventing the tool from shifting or falling off during heat treatment due to unstable clamping, thus ensuring the quality of heat treatment.

[0033] Please see Figure 1 and Figure 2 The driving mechanism includes a mounting plate 19, an electric cylinder 20, and two sets of slide rails 21. Both sets of slide rails 21 are connected to the top of the base plate 1. The bottom of the mounting platform 4 is slidably connected to the two sets of slide rails 21. The mounting plate 19 is connected to the top of the base plate 1. The electric cylinder 20 is connected to one side of the mounting plate 19, and its output end is connected to one side of the mounting platform 4. The cooperation of the mounting plate 19, the electric cylinder 20, and the two sets of slide rails 21 in the driving mechanism provides a stable and efficient driving method for the movement of the mounting platform 4 and the clamping mechanism. The electric cylinder 20, as a power source, enables the smooth and uniform movement of the mounting platform 4, ensuring the positional accuracy of the tool body 3 when entering and exiting the heating furnace body 2, and avoiding tool collisions or positional deviations due to unstable movement. The sliding cooperation between the two sets of slide rails 21 and the mounting platform 4 further improves the guidance and stability of the movement process, reduces mechanical wear, and extends the service life of the equipment. Compared to existing technologies that may rely on manual operation, this propulsion mechanism enables semi-automatic operation of the cutting tool entering and exiting the heating furnace, significantly reducing the intensity of manual labor, while improving the continuity and reliability of the heat treatment process, making the operation of the cutting tool entering and exiting the high-temperature environment safer and more controllable.

[0034] Please see Figures 1-3The adjustment mechanism includes an adjusting screw 22, which is threadedly connected to the side of the movable block 10 away from the movable clamping plate 6. The cut surface 18 of the turntable 14 is in contact with the adjusting screw 22. The design of the adjusting screw 22 being threadedly connected to the movable block 10 and in contact with the cut surface 18 of the turntable 14 allows for precise fine-tuning of the clamping force. Operators can rotate the adjusting screw 22 to change its relative position to the movable block 10, thereby adjusting the clamping tightness of the movable clamping plate 6 on the tool body 3. This adapts to the clamping needs of tools of different materials and thicknesses, preventing tool deformation due to excessive clamping or slippage due to excessive looseness. This threaded adjustment method has a self-locking function, maintaining a stable clamping force after adjustment. Combined with the rotation of the turntable 14, it not only continues the advantage of rapid adjustment but also improves the accuracy and reliability of clamping, further optimizing the adaptability and practicality of the clamping mechanism.

[0035] Please see Figures 1-4 Each of the two sets of first slide rods 12 is fitted with two sets of second springs 23. One end of each set of second springs 23 is connected to the first fixed plate 13 near the movable clamping plate 6, and the other end of each set of second springs 23 is connected to the slide plate 11 near the movable clamping plate 6. The two sets of second springs 23 can push the moving block 10 and the movable clamping plate 6 away from the tool. The second springs 23 fitted on the two sets of first slide rods 12 play an active reset role during the tool release process. When the turntable 14 is rotated to release the pushing force on the moving block 10 by the adjustment mechanism, the elastic restoring force of the second springs 23 can push the slide plate 11 and the moving block 10 away from the tool, causing the movable clamping plate 6 to automatically release without manual pulling, making the tool disassembly process more convenient and efficient.

[0036] Please see Figures 1-3 The fixture also includes two sets of guide rods 24, one end of which is connected to the fixed clamping plate 5. The movable clamping plate 6 is slidably connected to the two sets of guide rods 24. The two sets of guide rods 24 connect the fixed clamping plate 5 and the movable clamping plate 6, and the movable clamping plate 6 is slidably engaged with the guide rods 24, providing additional stable guidance for the movement of the movable clamping plate 6. When the movable clamping plate 6 moves with the moving block 10, the guide rods 24 limit its horizontal displacement, ensuring that the movable clamping plate 6 always remains parallel to the fixed clamping plate 5, so that the force on both sides of the tool body 3 is even, avoiding unstable clamping or tool tilting caused by the tilting of the movable clamping plate 6. This design enhances the structural rigidity of the clamping mechanism, especially when clamping long or heavy tools, effectively preventing deformation of the movable clamping plate 6, ensuring the accuracy and stability of the clamping process, and further improving the reliability of heat treatment operations.

[0037] Please see Figure 3Both the fixed clamping plate 5 and the movable clamping plate 6 have multiple sets of anti-slip grooves 25 on one side of the tool body 3, which are used to prevent slippage. The multiple sets of anti-slip grooves 25 on the inner side of the fixed clamping plate 5 and the movable clamping plate 6 significantly improve the clamping stability by increasing the friction between the clamping plate and the tool body 3. During heat treatment, the tool may experience slight displacement due to thermal expansion and contraction. The anti-slip grooves 25 effectively suppress this displacement, preventing the tool from slipping or shifting position at high temperatures. Simultaneously, the design of the anti-slip grooves 25 enhances clamping stability without damaging the tool surface, making it particularly suitable for tools with smooth surfaces or irregular shapes. This further expands the applicability of the fixture, ensuring precise fixation of the tool position during heat treatment and guaranteeing the quality of heat treatment.

[0038] Please see Figures 1-4 A handle 26 is provided on the side of the turntable 14 away from the second fixed plate 16, and the handle 26 is located away from the center area of ​​the turntable 14. This arrangement of the handle 26 away from the center of the turntable 14 conforms to ergonomic design, providing the operator with a more effortless point of force when rotating the turntable 14. Applying force through the handle 26 reduces operator hand fatigue, significantly improving operational efficiency, especially when frequent tool loading and unloading is required. Simultaneously, the position design of the handle 26 makes rotation more stable, preventing hand slippage and ensuring precise control during adjustment. This further optimizes the convenience of rapid tool loading and unloading operations, making the clamping or releasing of tools easier to control, and saving labor and time costs.

[0039] In summary, when using this quick-load fixture for heat treatment of mechanical cutting tools, the tool body 3 is first placed on the top of the mounting platform 4, so that one side of the tool body 3 is in contact with the inner side of the fixed clamping plate 5. The operator rotates the turntable 14. Since the connecting shaft 15 is far from the center of the turntable 14, the rotation of the turntable 14 drives the adjustment mechanism through the connecting shaft 15. The adjustment mechanism pushes the moving block 10 to move closer to the fixed clamping plate 5. The two sets of sliding plates 11 at the bottom of the moving block 10 slide along the two sets of first sliding rods 12, providing stable guidance for the movement of the moving block 10. The moving block 10 drives the movable rod 7 to slide in the slide groove 17 through the connecting block 9. The movable rod 7 pushes the movable clamping plate 6 closer to the tool body 3 until the movable clamping plate 6 is tightly in contact with the other side of the tool body 3. At this time, the first spring 8 is compressed, using its elastic potential energy to provide cushioning and ensure a firm clamping.

[0040] When it is necessary to remove the tool, the turntable 14 is rotated in the opposite direction, the pushing force of the adjusting mechanism on the moving block 10 is released, and with the assistance of the second spring 23, the movable rod 7 drives the movable clamp 6 to move away from the tool body 3, releasing the tool and completing the disassembly of the tool.

[0041] During the heat treatment process, the pushing mechanism is activated, and the electric cylinder 20 pushes the mounting platform 4 to move smoothly along the two sets of slide rails 21, driving the clamping mechanism and the tool body 3 into the heating furnace body 2 for heating, heat preservation, and other heat treatment operations. After the heat treatment is completed, the pushing mechanism moves the mounting platform 4 and the tool body 3 out of the heating furnace body 2, realizing automated or semi-automated operation of the tool entering and leaving the heating furnace. The entire process does not require direct human contact with the high-temperature environment, making the operation safe and efficient.

[0042] This electric cylinder 20 is a commercially available device known to those skilled in the art. We are simply using it here without making any structural or functional improvements, which we will not elaborate on here. The electric cylinder is equipped with a matching control switch, and the installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator.

[0043] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
