Description

TECHNICAL FIELD

[0001] The utility model relates to honing fixture technical field, specifically, relate to a kind of clamping device for round honing head. BACKGROUND

[0002] In manufacturing industry, especially in precision machining field, honing is widely used as a key finishing method to improve workpiece surface quality and dimensional accuracy. Especially in the automobile, aviation, die and other industries, the machining accuracy of hole structure is extremely high, and honing process has become an indispensable link. However, in actual operation, especially for open hole (non-circular hole) honing operation, it faces a series of challenges.

[0003] Due to the particularity of the shape of open hole, the honing head is easy to produce yarn drop or edge collapse when entering and exiting the hole, which not only affects the processing quality, but also increases the material loss and the difficulty of subsequent repair. In order to overcome this problem, the traditional solution is to modify the flat part of honing head oil stone strip to circular arc surface that matches the hole diameter of the workpiece to be honed. This method effectively avoids the damage of yarn and the collapse of hole edge by accurately matching the shape of oil stone strip and hole diameter, ensuring the stability of honing process and processing quality.

[0004] However, this traditional method brings new challenges in cost and management. Because of the variety of products, each different size of hole diameter needs to be made into corresponding round sleeve, which undoubtedly greatly increases the production cost. At the same time, with the increase of the use frequency of round sleeve, its wear degree gradually increases, eventually leading to scrap, further aggravating the cost waste. More troublesome is that a large number of different specifications of round sleeve not only increases the complexity of production management, but also brings great pressure to storage space.

[0005] Therefore, the existing technical solution not only solves the problem of open hole honing, but also exposes obvious limitations. These limitations mainly reflect in the following aspects: first, the over-reliance on round sleeve leads to high production cost; second, the frequent replacement and maintenance of round sleeve increase the management difficulty; third, it is difficult to quickly adapt to the machining demand of different size hole diameter, which affects the production efficiency.

[0006] Therefore, the industry urgently needs a new device or method that can reduce the dependence on round sleeve, reduce production cost, simplify management process and quickly adjust to different size hole diameter under the premise of ensuring processing quality. Such innovation will help promote the development of honing technology and improve the overall competitiveness of manufacturing industry. INVENTION CONTENTS

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0031] The terms "first", "second" are only for description purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0032] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] As in the background art, the traditional solution is to modify the flat part of the honing head oil stone strip to a circular arc surface that matches the aperture of the workpiece to be honed. This method effectively avoids damage to the yarn strip and collapse of the hole edge by precisely matching the shape of the oil stone strip and the aperture, ensuring the stability of the honing process and the processing quality.

[0034] However, this traditional method brings new challenges in cost and management. Because of the variety of products, each different size of aperture needs to be made with a corresponding round sleeve, which undoubtedly greatly increases the production cost. At the same time, as the number of uses of the round sleeve increases, the degree of wear gradually intensifies, eventually leading to scrap, further exacerbating the cost waste. More troublesome is that a large number of different specifications of round sleeves not only increase the complexity of production management, but also bring great pressure to storage space.

[0035] Therefore, the existing technical solution, while solving the problem of open hole honing, also exposes obvious limitations. These limitations mainly manifest in the following aspects: first, the over-reliance on round sleeves leads to high production costs; second, the frequent replacement and maintenance of round sleeves increases management difficulty; third, it is difficult to quickly adapt to the processing needs of different size apertures, affecting production efficiency.

[0036] In view of this, there is an urgent need in the industry for a new device or method that can reduce the dependence on round sleeves, reduce production costs, simplify management processes, and quickly adjust to different sizes of apertures while ensuring processing quality. Such innovation will help promote the development of honing technology and improve the overall competitiveness of the manufacturing industry.

[0037] To improve the above problems, the application provides a clamping device for a round honing head, which reduces the need for multiple round sleeve sets by using an adjustable honing head and related components. In traditional honing processes, a separate round sleeve set is needed for each size of the hole diameter, which not only increases production costs, but also gradually wears out and eventually becomes scrap as the number of uses increases, further exacerbating cost waste. The application significantly reduces manufacturing and maintenance costs by adapting to different sizes of hole diameters with a universal device. Due to the need for a large number of round sleeve specifications, production management and storage become more convenient. In traditional methods, a large number of round sleeves are not only difficult to manage, but also occupy a large amount of storage space. By reducing the number of round sleeves, the production line becomes more orderly and organized, and production delays or errors caused by poor management are reduced. The device of the application can be quickly adjusted to adapt to different sizes of hole diameters, improving production efficiency. In traditional honing processes, replacing the round sleeve is a time-consuming process. However, the application can be adjusted by simply screwing in or out the adjusting jack, greatly shortening the preparation time. This ability to quickly adjust makes the production line more flexible in responding to different production needs. The device of the application can ensure accurate matching of the oil stone strip and the hole diameter of the workpiece, avoiding the phenomenon of yarn strip being knocked off or edge collapse, thereby improving the processing quality. In traditional honing processes, due to the wear or mismatch of the round sleeve, the processing quality may be unstable. However, the application ensures consistency and precision in each processing through precise mechanical adjustment. This high-precision processing capability helps to improve product quality and reliability. The device of the application is designed rationally and is easy to operate, even non-professionals can quickly get started. Traditional honing processes may require experienced operators to ensure processing quality. However, the device of the application simplifies the operation process, reducing the skill requirements for operators. This easy-to-operate feature helps to reduce labor costs and improve production efficiency. The device of the application has a simple structure and is easy to maintain. In traditional honing processes, replacing and maintaining the round sleeve may involve complex mechanical adjustments and part replacement. However, the device of the application is designed modularly, making maintenance work simpler and faster. This easy-to-maintain feature helps to reduce downtime and extend the service life of the equipment. The device of the application has high flexibility and can be quickly adjusted according to actual needs to meet the processing needs of different workpieces and different hole diameters. This flexibility enables the production line to quickly adapt to market changes and customer needs. The design of the anti-loose jack ensures the stability of the adjusting jack, preventing loosening during use and enhancing the reliability and safety of the equipment. This reliable design helps to reduce failure rates and improve production efficiency.

[0038] Referring to Figure 1 As shown in the drawings, the clamping device for a round honing head according to an embodiment of the application comprises:

[0039] The honing head body 1 is transversely arranged on the cylindrical grinding machine.

[0040] The clamping assembly 2 connects the honing head body 1 with the cylindrical grinding machine, and the cylindrical grinding machine drives the honing head body 1 to rotate, and performs circular grinding on the honing head oil stone strip on the honing head body 1.

[0041] Specifically, the honing head body 1 is the core part of the entire device, which is transversely arranged on the cylindrical grinding machine. The honing head body 1 is usually composed of multiple components, including the honing head oil stone strip, the honing head seat, the spring collet, etc.; the honing head body 1 is connected with the cylindrical grinding machine through the clamping assembly 2. The function of this clamping assembly 2 is to ensure that the honing head body 1 is stably fixed on the cylindrical grinding machine and can withstand the force generated during the honing process. The cylindrical grinding machine is a machine tool used for cylindrical grinding of workpieces. The cylindrical grinding machine not only drives the honing head body 1 to rotate, but also performs circular grinding on the honing head oil stone strip on the honing head body 1. This means that the cylindrical grinding machine has a high-precision control system that can ensure that the honing head oil stone strip maintains the correct shape and size during the grinding process. The cylindrical grinding machine precisely controls the movement of the honing head body and the honing head oil stone strip to grind according to the predetermined trajectory and speed. In this way, the outer cylindrical surface of the workpiece is processed into the required circular profile.

[0042] In some specific embodiments, the clamping assembly 2 includes:

[0043] The head tensioning sleeve 3 is arranged at the head of the honing head body 1, and the end of the head tensioning sleeve 3 away from the honing head body 1 abuts and fits with the front top center 4 on the upper end of the cylindrical grinding machine.

[0044] The tail tensioning disc 5 is arranged at the tail of the honing head body 1, and the end of the tail tensioning disc 5 away from the honing head body 1 abuts and fits with the rear top center 6 on the cylindrical grinding machine.

[0045] Specifically, the head tensioning sleeve 3 and the tail top disc 5 in the clamping assembly 2 are the key components for fixing the honing head body 1. They are respectively located at the head and tail of the honing head body, and abut with the front center 4 and the rear center 6 on the cylindrical grinding machine to ensure that the honing head body 1 remains stable during the grinding process. The head tensioning sleeve 3 is arranged at the head of the honing head body 1, and the end away from the honing head body 1 abuts with the front center 4 on the cylindrical grinding machine. This design can ensure that the honing head body 1 does not move axially during rotation, thereby improving the machining accuracy. At the same time, the head tensioning sleeve 3 can also withstand a certain radial force to prevent the honing head body 1 from deforming due to external force. The tail top disc 5 is arranged at the tail of the honing head body 1, and the end away from the honing head body 1 abuts with the rear center 6 on the cylindrical grinding machine. The main function of the tail top disc is to limit the axial movement of the honing head body 1 to ensure that it remains stable during the grinding process. In addition, the tail top disc 5 can also withstand a certain torque to prevent the honing head body 1 from being damaged due to excessive torque. The head tensioning sleeve 3 and the tail top disc 5 are important components of the clamping assembly 2, which abut with the front center 4 and the rear center 6 on the cylindrical grinding machine to achieve effective fixation of the honing head body 1. This design not only improves the machining accuracy, but also prolongs the service life of the equipment.

[0046] In some embodiments, the head tensioning sleeve 3 is provided with a central threaded hole 7, and the adjusting stud 10 is connected with the central threaded hole 7 of the head tensioning sleeve 3 through external threads. One end of the adjusting stud 10 contacts the head end surface of the honing head body 1.

[0047] In some embodiments, the head tensioning sleeve 3 is provided with a through hole 8 near the side close to the honing head body 1 for hanging pins to pass through. The head tensioning sleeve 3 is connected with the head of the honing head body 1 through hanging pins near the side close to the honing head body 1.

[0048] Specifically, by adjusting the cooperation between the top screw 10 and the hanging pin, it can ensure that the connection between the head tensioning sleeve 3 and the honing head body 1 is more stable and stable. This stable connection helps to reduce loosening or falling caused by vibration or impact force during processing, thereby improving processing accuracy and safety, and the design of the hanging pin makes the installation and disassembly of the head tensioning sleeve 3 simple and fast. The operator can easily fix the head tensioning sleeve 3 on the honing head body 1 through the hanging pin, or quickly disassemble it when maintenance is needed. This greatly reduces the downtime of the equipment and improves production efficiency; adjusting the cooperation between the top screw 10 and the hanging pin not only provides a stable connection, but also enhances the structural strength of the entire device. This design can withstand greater radial force and torque, thereby prolonging the service life of the equipment. Since the design of the top screw 10 and the hanging pin has a certain flexibility, this connection method can adapt to honing head bodies 1 and cylindrical grinding machines of different specifications. This makes the same set of clamping assembly 2 can be used on different equipment and workpieces, improving the versatility and adaptability of the equipment. The head tensioning sleeve 3 is connected to the honing head body 1 through the central threaded hole 7, through hole 8 and hanging pin on the side close to the honing head body 1. The design not only improves the stability and reliability of the connection, but also facilitates installation and maintenance, enhances structural strength, adapts to multiple specifications, reduces manufacturing costs, improves processing accuracy, and optimizes space layout. These advantages collectively enhance the performance and user experience of the entire device.

[0049] In some embodiments, the head tensioning sleeve 3 is provided with a first central hole 9 on the side away from the honing head body 1, and the inner diameter of the first central hole 9 is matched with the outer diameter of the front center 4.

[0050] In some embodiments, the first central hole 9 is in communication with the central threaded hole 7.

[0051] In some embodiments, the clamping assembly 2 further comprises:

[0052] The adjusting top screw 10 extends into the head tensioning sleeve 3 through the first central hole 9, and one end of the adjusting top screw 10 abuts against the top rod 11 of the head of the honing head body 1.

[0053] The anti-loosening top screw 12 extends into the head tensioning sleeve 3 through the first central hole 9, and is arranged on the side away from the honing head body 1 of the adjusting top screw 10. One end of the anti-loosening top screw 12 abuts against the other end of the adjusting top screw 10, and the other end of the anti-loosening top screw 12 is used to abut against the front center 4.

[0054] In some embodiments, the tail tensioning disc 5 is provided with a second central hole 13 on the side away from the honing head body 1, and the inner diameter of the second central hole 13 is matched with the outer diameter of the rear center 6.

[0055] In some embodiments, the tail portion of the head body 1 of the honing head is fixedly connected by bolts.

[0056] Specifically, the inner diameter of the first central hole 9 is matched with the outer diameter of the front center 4, ensuring the tight fit between the head tension sleeve 3 and the front center 4. This precise fit can effectively prevent loosening or falling off due to vibration or impact force during processing, thereby improving processing accuracy and safety; the design of the adjusting screw 10 and the anti-loose screw 12 makes the installation and disassembly of the head tension sleeve 3 simple and fast. The operator can easily fix the head tension sleeve 3 on the honing head body 1 by adjusting the screw 10, or quickly disassemble it when maintenance is needed. This greatly reduces the downtime of the equipment and improves production efficiency; the cooperation of the central threaded hole 7, the through hole 8, the hanging pin, and the adjusting screw 10 and the anti-loose screw 12 not only provides stable connection, but also enhances the structural strength of the entire device. This design can withstand greater radial force and torque, thereby prolonging the service life of the equipment. Because the first central hole 9 and the adjusting screw 10 and the anti-loose screw 12 have a certain flexibility in design, this connection method can adapt to honing head bodies 1 and cylindrical grinding machines of different specifications. This makes the same set of clamping assembly 2 can be used on different equipment and workpieces, improving the versatility and adaptability of the equipment. The design of the anti-loose screw 12 can effectively prevent the adjusting screw 10 from loosening due to vibration or other reasons during use, thereby improving the safety of the equipment. At the same time, the tail portion of the honing head body 1 is fixedly connected to the tail portion of the honing head body 1 by bolts, which also increases the overall stability and safety.

[0057] In some embodiments, the head tension sleeve 3, the tail portion of the honing head body 1, the front center 4, and the rear center 6 are coaxial.

[0058] Specifically, the head tension sleeve 3 is connected through the hanging pin of the honing head body 1 head, and then the adjusting screw 10 is installed in the head tension sleeve 3 while pressing against the honing head body 1 top rod 11, and then the honing head body 1 is expanded or contracted to a diameter slightly larger than the required diameter by rotating the adjusting screw 10 in or out, and then the anti-loose screw 12 is installed in the head tension sleeve 3 and is pressed against the adjusting screw 10 to prevent the adjusting screw 10 from loosening, and then the tail portion of the honing head body 1 is installed on the tail portion of the honing head body 1, and the honing head body 1 and the clamping device become one, and then the outer circle of the honing head body 1 is finished on the grinding machine after the two centers of the grinding machine are tightened.
