Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a device that can quickly clamp round dies of various sizes. Background Technology

[0002] A round die is a tool used for machining external threads; its main function is to create threads by cutting metal surfaces. In practical applications, round dies are typically fixed to the machine die holder of a lathe using fastening screws to ensure stability and precision during machining. However, this fixing method has certain limitations.

[0003] When machining threads of different specifications, it is often necessary to change to a matching die holder. This not only increases the complexity of operation but also leads to inconvenience in carrying and storing the die. Since different specifications of round dies and die holders cannot be mixed, users need to prepare corresponding tools and equipment for each thread specification, which undoubtedly increases material waste and costs. Furthermore, changing tools and adjusting equipment requires additional time and effort, so this limitation may also affect work efficiency. Therefore, there is an urgent need for a device that can accommodate multiple specifications of round dies. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0024] This application provides a device that can quickly clamp round dies of various sizes, which can solve the technical problem in the prior art that the die holder cannot flexibly adapt to round dies of different sizes.

[0025] Figure 1 This application provides a structural schematic diagram of a device for quickly clamping round dies of various sizes. Figure 2 Side views of the forward-mounted and reverse-mounted chuck jaws provided in this application. See also... Figure 1 and Figure 2 The apparatus for quickly clamping round dies of various sizes provided in this application includes:

[0026] The positive mounting jaw disk 4 has multiple positive mounting jaws 401 circumferentially arranged on the side facing the round tooth 5, and the bottom of each positive mounting jaw 401 is provided with a first moving member for realizing the radial movement of the positive mounting jaw 401; the negative mounting jaw disk is fixedly connected to the side of the positive mounting jaw disk 4 away from the round tooth 5, and the side of the negative mounting jaw disk away from the positive mounting jaw disk 4 has multiple negative mounting jaws 402 circumferentially arranged with the opposite jaw direction to the positive mounting jaws 401; the sliding sleeve 3 has multiple negative mounting jaws 402 clamped at one end of the sliding sleeve 3, and the other end of the sliding sleeve 3 is fitted with an adapter sleeve 2 for the sliding sleeve 3 to extend or retract.

[0027] Specifically, the round die 5 is a tool used to process external threads. Its main function is to form threads by cutting the metal surface. In actual operation, the round die 5 is clamped in the chuck 4, and the workpiece 6 to be processed is clamped in the lathe chuck 7. At the same time, the end of the adapter sleeve 2 away from the sliding sleeve 3 is fixedly connected to the lathe tailstock 1. The lathe chuck 7 cooperates with the lathe tailstock 1 to ensure the coaxiality of the workpiece to be processed with the round die 5.

[0028] The forward-mounted jaw 401 is used to clamp round dies 5 of different sizes, and the reverse-mounted jaw 402 is used to clamp one end of the sliding sleeve 3. The sliding sleeve 3 can slide inside the adapter sleeve 2 so that the whole device can clamp round dies 5 of different sizes and lengths, thus improving the adaptability of the device.

[0029] Figure 3 A partial sectional view of the caliper disc 4 provided in this application. Figure 4 A partial side sectional view of the positive mounting jaw disk 4 provided in this application. (Refer to reference...) Figure 3 and Figure 4 The mounting jaw disc 4 includes: a first housing 408, which encloses a mounting cavity, and a first adjustment hole 403 communicating with the mounting cavity is provided on the side of the first housing 408; a first conical wheel, which is inserted into the first adjustment hole 403, and a first thread is provided on the end of the first conical wheel facing the mounting cavity; and a first bevel gear 405, which is mounted in the mounting cavity, and includes a second thread provided on the side of the first bevel gear 405 and a planar thread 406 provided on the top surface of the first bevel gear 405, wherein the second thread meshes with the first thread to realize the rotation of the first conical wheel to drive the rotation of the first bevel gear 405.

[0030] Specifically, the first moving part is a slider, one end of which is fixedly connected to the positive mounting jaw 401, and the other end of which is provided with a third thread that meshes with the planar thread 406. The first bevel gear 405 rotates to realize the radial movement of the positive mounting jaw 401.

[0031] In actual operation, the round die 5 is placed between the jaws of the chuck disc 4, ensuring that the central axis of the round die 5 is aligned with the central axis of the chuck disc 4. The first conical wheel is inserted into the first adjustment hole 403, and the first conical wheel is rotated manually. The first thread of the first conical wheel meshes with the second thread of the first bevel gear 405, thereby changing the rotation direction from vertical to horizontal, driving the first bevel gear 405 to rotate. Further, the large bevel gear of the first bevel gear 405 drives the planar thread 406 to rotate. The planar thread 406 meshes with the third thread at the bottom of the slider. When the planar thread 406 rotates, multiple chuck jaws 401 move radially toward the center, gradually clamping the round die 5. The first conical wheel continues to rotate until the round die 5 is firmly clamped. After the round die 5 is firmly clamped, ensure that the round die 5 and the lathe tailstock 1 are coaxial to ensure the machining accuracy of the workpiece 6.

[0032] Through the coordinated operation of the first bevel wheel, the first bevel gear 405, and the slider, the radial movement of the mounting jaw 401 is achieved. This not only improves the flexibility and accuracy of the clamping device but also ensures its stability and durability. Manual adjustment allows for the rapid clamping of round dies 5 of different sizes, significantly improving the machining efficiency and adaptability of the clamping device.

[0033] In this embodiment, the forward-mounted jaw 401 is L-shaped and stepped, and the reverse-mounted jaw 402 is an inverted L-shaped and stepped.

[0034] Specifically, the higher steps of the multiple L-shaped stepped forward jaws 401 are close to the axis of the forward jaw disk 4, and the multiple forward jaws 401 enclose to form a first jaw clamping area for clamping the round die 5. The lower steps of the multiple inverted L-shaped stepped reverse jaws 402 are close to the axis of the reverse jaw disk, and the multiple reverse jaws 402 enclose to form a second jaw clamping area for clamping the sliding sleeve 3.

[0035] In the embodiments of this application, the diameter of the first jaw clamping area is 0mm to 60mm, and the diameter of the second jaw clamping area is 30mm to 90mm.

[0036] The high-step design of the forward-mounted jaw 401 enables it to firmly clamp small-diameter round dies 5, ensuring the stability of the round dies 5 during machining. The low-step design of the reverse-mounted jaw 402 enables it to accommodate larger sliding sleeves 3, ensuring the stability of the sliding sleeves 3 during axial sliding.

[0037] In this embodiment of the application, each reverse-mounting jaw 402 is provided with a second moving member at its bottom for realizing radial movement of the reverse-mounting jaw 402.

[0038] Specifically, similar to the forward-mounted chuck disc 4, the reverse-mounted chuck disc includes: a second outer shell, which encloses a mounting cavity, and a second adjustment hole 404 communicating with the mounting cavity is provided on the side of the second outer shell; a second conical wheel, which is inserted into the second adjustment hole 404, and a fourth thread is provided on the end of the second conical wheel facing the mounting cavity; and a second bevel gear, which is mounted in the mounting cavity, and includes a fifth thread provided on the side of the second bevel gear and a planar thread provided on the top surface of the second bevel gear, wherein the fourth thread and the fifth thread mesh to realize the rotation of the second conical wheel, thereby driving the rotation of the second bevel gear. Specifically, the second moving part is also a slider, one end of which is fixedly connected to the reverse-mounted chuck 402, and the other end of which is provided with a third thread that meshes with the planar thread. The rotation of the second bevel gear realizes the radial movement of the reverse-mounted chuck 402.

[0039] In actual operation, the sliding sleeve 3 is placed between the jaws of the reverse-mounted chuck disc, ensuring that the central axis of the sliding sleeve 3 is aligned with the central axis of the reverse-mounted chuck disc. The second conical wheel is inserted into the second adjusting hole 404, and the second conical wheel is rotated manually. The fourth thread of the second conical wheel meshes with the fifth thread of the second bevel gear, thereby changing the rotation direction from vertical to horizontal, driving the second bevel gear to rotate. Further, the large bevel gear of the second bevel gear drives the planar thread to rotate, and the planar thread meshes with the third thread at the bottom of the slide block. When the planar thread rotates, multiple reverse-mounted chucks 402 move radially toward the center, gradually clamping the sliding sleeve 3. The second conical wheel continues to rotate until the sliding sleeve 3 is firmly clamped. After the sliding sleeve 3 is firmly clamped, ensure that the sliding sleeve 3 and the lathe tailstock 1 are coaxial to ensure the stability of the sliding sleeve 3.

[0040] Through the coordinated work of the second bevel wheel, the second bevel gear and the slider, the radial movement of the reverse clamping jaw 402 is realized, thereby realizing the clamping of the sliding sleeve 3. Then, the overall length of the device can be adjusted by the axial sliding of the sliding sleeve 3 to adapt to the round die 5 of different lengths or heights.

[0041] In this embodiment, the first outer shell 408 and the second outer shell are integrally formed or welded together. The first outer shell 408 and the second outer shell are made of lightweight alloy, which improves the strength and stability of the overall device and ensures the accuracy of the workpiece 6 processing.

[0042] A sealing plate is also provided on the inner wall of the first housing 408 and the second housing. The sealing plate is used to prevent dust and debris from entering the inside of the forward-mounted chuck 4 or the reverse-mounted chuck, thus protecting the internal mechanical structure.

[0043] In this embodiment, the adapter tube 2 has a pin hole 8 on its side. The pin 8 passes through the pin hole 8 and abuts against the sliding sleeve 3 to achieve relative fixation between the adapter tube 2 and the sliding sleeve 3.

[0044] Specifically, after the sliding sleeve 3 is adjusted to the appropriate position, the pin 8 is inserted into the pin hole on the side of the adapter sleeve 2, so that the pin 8 abuts against the sliding sleeve 3, thereby preventing further movement of the sliding sleeve 3 and locking the position of the sliding sleeve 3, so that the overall device remains stable during the machining of the round die 5. At the same time, the adapter sleeve 2 can be fixedly connected to the lathe tailstock 1 through the Morse taper sleeve, thereby providing positioning and connection between the adapter sleeve 2 and the lathe tailstock 1, and also preventing the adapter sleeve 2 from loosening due to vibration or cutting force.

[0045] In this embodiment, the positive mounting jaw disc 4, the reverse mounting jaw disc, the sliding sleeve 3, and the adapter sleeve 2 are located on the same axis.

[0046] The coaxiality of the positive chuck plate 4, the reverse chuck plate, the sliding sleeve 3, and the adapter sleeve 2 enables the components to work together during operation, reducing machining errors caused by component misalignment.

[0047] This application embodiment employs a combination design of a positive-mount chuck disc and a negative-mount chuck disc. By configuring the positive-mount chuck disc's positive jaws as radially movable jaws, it can accommodate round dies of different sizes. Simultaneously, the negative-mount chuck disc's negative jaws are configured with a direction opposite to that of the positive-mount chucks, allowing it to clamp large-sized parts. This application embodiment also includes a sliding sleeve that can move circumferentially within an adapter sleeve. Thus, the negative-mount chuck disc and the positive-mount chuck disc connected to the sliding sleeve can accommodate round dies of different lengths, thereby improving the overall flexibility and adaptability of the device. When machining threads of different specifications, there is no need to change the matching machine die holder, avoiding time wasted on tool changes and equipment adjustments, and improving machining efficiency.
