Description

Technical Field

[0001] The invention relates to the technical field of honing fixtures, and in particular to a clamping device for a circular honing head. Background Art

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

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

[0004] However, this traditional method has brought new challenges in terms of cost and management. Due to the wide variety of products, each different size of aperture needs to be produced separately, which undoubtedly greatly increases the production cost. At the same time, as the number of times the gauge sleeve is used increases, its degree of wear gradually increases, eventually leading to scrapping, further exacerbating the cost waste. What is more difficult is that a large number of gauge sleeves of different specifications not only increases the complexity of production management, but also puts huge pressure on storage space.

[0005] Therefore, while the existing technical solutions solve the problem of open hole honing, they also expose obvious limitations. These limitations are mainly reflected in the following aspects: first, excessive reliance on gauge sleeves leads to high production costs; second, frequent replacement and maintenance of gauge sleeves increase management difficulties; third, it is difficult to quickly adapt to the processing needs of different hole sizes, affecting production efficiency.

[0006] In view of this, the industry urgently needs a new device or method that can reduce the dependence on gauge sleeves, reduce production costs, simplify management processes, and be able to 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. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] As mentioned in the background technology, the traditional solution is to modify the flat part of the honing head oilstone strip into a circular arc surface that matches the hole diameter of the workpiece to be honed. This method effectively avoids the damage of the yarn strip and the cracking of the hole edge by accurately matching the shape of the oilstone strip and the hole diameter, ensuring the stability and processing quality of the honing process.

[0036] However, this traditional method has brought new challenges in terms of cost and management. Due to the wide variety of products, each different size of aperture needs to be produced separately, which undoubtedly greatly increases the production cost. At the same time, as the number of times the gauge sleeve is used increases, its degree of wear gradually increases, eventually leading to scrapping, further exacerbating the cost waste. What is more difficult is that a large number of gauge sleeves of different specifications not only increases the complexity of production management, but also puts huge pressure on storage space.

[0037] Therefore, while the existing technical solutions solve the problem of open hole honing, they also expose obvious limitations. These limitations are mainly reflected in the following aspects: first, excessive reliance on gauge sleeves leads to high production costs; second, frequent replacement and maintenance of gauge sleeves increase management difficulties; third, it is difficult to quickly adapt to the processing needs of different hole sizes, affecting production efficiency.

[0038] In view of this, the industry urgently needs a new device or method that can reduce the dependence on gauge sleeves, reduce production costs, simplify management processes, and be able to 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.

[0039] To improve the above problems, the present application proposes a clamping device for a gage honing head, which reduces the need for multiple gage sleeves by using an adjustable honing head and related components. In the traditional honing process, each size of aperture needs to be made separately for a corresponding gage sleeve, which not only increases the production cost, but also gradually wears out and eventually becomes scrapped as the number of uses increases, further exacerbating the cost waste. The present application uses a universal device to adapt to apertures of different sizes, significantly reducing manufacturing and maintenance costs. Since a large number of gage sleeve specifications are no longer required, production management and storage become simpler. In traditional methods, a large number of gage sleeves are not only difficult to manage, but also take up a lot of storage space. The present application reduces the number of gage sleeves, making the production line neater and more orderly, and also reduces production delays or errors caused by poor management. The device of the present application can be quickly adjusted to adapt to apertures of different sizes, thereby improving production efficiency. In the traditional honing process, replacing the gage sleeve is a time-consuming process. The present application can complete the adjustment by simply screwing in or out the adjustment screw, greatly shortening the preparation time. This ability to adjust quickly enables the production line to respond to different production needs more flexibly. The device of the present application can ensure the precise matching of the oilstone strip and the aperture of the workpiece, avoiding the phenomenon of the yarn strip being knocked off or the edge collapsing, thereby improving the processing quality. In the traditional honing process, the wear or mismatch of the gauge sleeve may cause unstable processing quality. The present application ensures the consistency and accuracy of each processing through precise mechanical adjustment. This high-precision processing capability helps to improve the quality and reliability of the product. The device of the present application is reasonably designed and easy to operate, so even non-professionals can quickly get started. The traditional honing process may require experienced operators to ensure the processing quality. The device of the present application reduces the requirements for operator skills by simplifying the operating process. This easy-to-operate feature helps to reduce labor costs and improve production efficiency. The device of the present application has a simple structure and is easy to maintain. In the traditional honing process, the replacement and maintenance of the gauge sleeve may involve complex mechanical adjustments and parts replacement. The device of the present application makes maintenance work simpler and faster through modular design. This easy-to-maintain feature helps to reduce downtime and extend the service life of the equipment. The device of the present application has high flexibility and can be quickly adjusted according to actual needs to meet the processing requirements of different workpieces and different hole diameters. This flexibility enables the production line to adapt to market changes and customer needs more quickly. The design of the anti-loosening top screw ensures the stability of the adjustment top screw, prevents loosening during use, and enhances the reliability and safety of the equipment. This reliable design helps reduce the failure rate and improve production efficiency.

[0040] See also Figure 1-3As shown, a clamping device for a circular honing head according to an embodiment of the present application comprises: a honing head body 1, the honing head body 1 is transversely arranged on an external cylindrical grinding machine;

[0041] The clamping assembly 2, the honing head body 1 is connected to the cylindrical grinder through the clamping assembly 2, the cylindrical grinder drives the honing head body 1 to rotate, and the cylindrical grinder regularizes the honing head oilstone strip on the honing head body 1;

[0042] The clamping assembly 2 comprises:

[0043] A head tension sleeve 3, which is arranged at the head of the honing head body 1, and an end of the head tension sleeve 3 away from the honing head body 1 abuts against and fits with the front center 4 at the upper end of the cylindrical grinder;

[0044] The tail tightening plate 5 is arranged at the tail of the honing head body 1, and one end of the tail tightening plate 5 away from the honing head body 1 abuts against the rear center 6 on the cylindrical grinder.

[0045] Specifically, the honing head body 1 is the core part of the whole device, which is horizontally arranged on the cylindrical grinder. The honing head body 1 is usually composed of multiple components, including a honing head oilstone, a honing head seat, a spring chuck, etc.; the honing head body 1 is connected to the cylindrical grinder through a 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 grinder and can withstand the force generated during the honing process. The cylindrical grinder is a machine tool used for cylindrical grinding of workpieces. The cylindrical grinder not only drives the honing head body 1 to rotate, but also rounds the honing head oilstone on the honing head body 1. This means that the cylindrical grinder has a high-precision control system that can ensure that the honing head oilstone maintains the correct shape and size during the grinding process. The cylindrical grinder accurately controls the movement of the honing head body and the honing head oilstone so that it can be ground according to a predetermined trajectory and speed. In this way, the outer cylindrical surface of the workpiece is machined into the required circular contour.

[0046] The head tension sleeve 3 and the tail tightening plate 5 in the clamping assembly 2 are 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 against the front center 4 and the rear center 6 on the cylindrical grinder to ensure that the honing head body 1 remains stable during the grinding process. The head tension sleeve 3 is arranged at the head of the honing head body 1, and the end away from the honing head body 1 abuts against the front center 4 at the upper end of the cylindrical grinder. This design can ensure that the honing head body 1 does not move axially during the rotation process, thereby improving the processing accuracy. At the same time, the head tension sleeve 3 can also withstand a certain radial force to prevent the honing head body 1 from being deformed due to external force. The tail tightening plate 5 is arranged at the tail of the honing head body 1, and the end away from the honing head body 1 abuts against the rear center 6 on the cylindrical grinder. The main function of the tail tightening plate is to limit the axial movement of the honing head body 1 and ensure that it always remains stable during the grinding process. In addition, the tail tightening plate 5 can also withstand a certain torque to prevent the honing head body 1 from being damaged due to excessive torque. The head tightening sleeve 3 and the tail tightening plate 5 are important components of the clamping assembly 2. They are in contact with the front center 4 and the rear center 6 on the cylindrical grinder to effectively fix the honing head body 1. This design not only improves the processing accuracy, but also extends the service life of the equipment.

[0047] In some specific embodiments, the head tension sleeve 3 is provided with a central threaded hole 7, and the adjusting top screw 10 is connected with the central threaded hole 7 of the head tension sleeve 3 through an external circular thread, and one end of the adjusting top screw 10 contacts the end face of the head of the honing head body 1.

[0048] In some specific embodiments, a through hole 8 for a hanging pin to pass through is penetrated on the side of the head tension sleeve 3 close to the honing head body 1, and the side of the head tension sleeve 3 close to the honing head body 1 is connected to the head of the honing head body 1 through the hanging pin.

[0049] Specifically, by adjusting the cooperation of the top screw 10 and the hanging pin, it is possible to ensure that the connection between the head tension sleeve 3 and the honing head body 1 is tighter and more stable. This stable connection helps to reduce loosening or falling off due to vibration or impact force during processing, thereby improving processing accuracy and safety. The design of the hanging pin makes the installation and removal of the head tension sleeve 3 simple and quick. The operator can easily fix the head tension sleeve 3 on the honing head body 1 through the hanging pin, or quickly remove it when maintenance is required. This greatly reduces the downtime of the equipment and improves production efficiency; the cooperation of the adjustment 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 extending the service life of the equipment. Since the design of the adjustment top screw 10 and the hanging pin has a certain flexibility, this connection method can adapt to honing head bodies 1 and cylindrical grinders of different specifications. This allows the same set of clamping components 2 to be used on different equipment and workpieces, improving the versatility and adaptability of the equipment. The design of the head tension sleeve 3 being connected to the head of the honing head body 1 through the central threaded hole 7, the adjusting top screw 10, the through hole 8 and the hanging pin on the side close to the honing head body 1 not only improves the stability and reliability of the connection, but also facilitates installation and maintenance, enhances the structural strength, adapts to a variety of specifications, reduces manufacturing costs, improves processing accuracy, and optimizes the spatial layout. These advantages together enhance the performance and user experience of the entire device.

[0054] An anti-loosening top screw 12 extends into the head tightening sleeve 3 through the first center hole 9.

[0056] In some specific embodiments, the inner diameter of the second center hole 13 matches the outer diameter of the rear tip 6 .

[0057] In some specific embodiments, the tail clamping plate 5 is fixedly connected to the tail of the honing head body 1 by bolts.

[0058] Specifically, the inner diameter of the first center hole 9 is matched with the outer diameter of the front top 4, ensuring a tight fit between the head tension sleeve 3 and the front top 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 adjustment screw 10 and the anti-loosening screw 12 makes the installation and removal of the head tension sleeve 3 simple and quick. The operator can easily fix the head tension sleeve 3 on the honing head body 1 by adjusting the screw 10, or quickly remove it when maintenance is required. This greatly reduces the downtime of the equipment and improves production efficiency; the center threaded hole 7, the through hole 8, the hanging pin, and the adjustment screw 10 and the anti-loosening screw 12 not only provide a stable connection, but also enhance the structural strength of the entire device. This design can withstand greater radial force and torque, thereby extending the service life of the equipment. Since the design of the first center hole 9 and the adjustment screw 10 and the anti-loosening screw 12 has a certain flexibility, this connection method can adapt to honing head bodies 1 and cylindrical grinders of different specifications. This allows the same set of clamping components 2 to be used on different devices and workpieces, improving the versatility and adaptability of the device. The design of the anti-loosening top screw 12 can effectively prevent the adjustment top screw 10 from loosening due to vibration or other reasons during use, thereby improving the safety of the device. At the same time, the tail clamping plate 5 is fixedly connected to the tail of the honing head body 1 by bolts, which also increases the overall stability and safety.

[0059] In some specific embodiments, the axis center lines of the head tension sleeve 3, the tail tension disk 5, the front center 4, and the rear center 6 coincide with each other.

[0060] Specifically, the head tightening sleeve 3 is connected with the hanging pin at the head of the honing head body 1, and then the adjusting top screw 10 is installed into the head tightening sleeve 3 and supported against the top rod 11 of the honing head body 1. Then, the honing head body 1 is expanded or shrunk to a diameter slightly larger than the required circle by screwing in or out the adjusting top screw 10. Then, the anti-loosening top screw 12 is installed into the head tightening sleeve 3 and tightened against the adjusting top screw 10 to prevent the adjusting top screw 10 from loosening. Then, the tail tightening plate 5 is installed at the tail of the honing head body 1 to make the honing head body 1 and the clamping device become one. After being tightened by the two tops of the grinding machine, the outer circle of the honing head body 1 is trimmed on the grinding machine.
