Description

Technical Field

[0001] This utility model relates to the field of transmission device technology, and in particular to a chain with a bearing plate and a transmission device using the chain. Background Technology

[0002] Chains, as a commonly used transmission device, have advantages such as high transmission efficiency and high reliability. With the development of industrial technology, chains can now be improved by adding control or sensing components. For example, certain technical means can be used to modify the outer chain plate to enable the installation of sensors and other components.

[0003] Existing methods involve directly tapping or welding screws to the pre-drilled holes on the support plate. Tapping, due to the relatively thin support plate, can lead to insecure installation and damaged threads when fixing the target with screws. Welding screws can cause misalignment or misalignment between the nut hole and the hole on the support plate, resulting in difficulty in installation or incorrect positioning after installation. Therefore, this invention proposes a chain with a support plate to at least partially solve the problems inherent in the prior art. Utility Model Content

[0004] In view of the above problems, the present invention is proposed to provide a chain with a bearing plate and a transmission device using the chain to overcome or at least partially solve the above problems.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 3 As shown, in some embodiments of this utility model, a chain with a support plate is provided, which may specifically include: a plurality of inner chain links 101, which are connected to outer chain plates 102 by pins 105 on both sides; at least one outer chain plate 102 on one side is provided with a support plate 103 bent outward at a right angle; the support plate 103 is fixedly riveted with a nut 104; the outer side of the nut 104 is flush with the support plate 103.

[0020] This utility model discloses a chain with a support plate, comprising several inner chain links 101, the two sides of which are connected to outer chain plates 102 via pins 105. On at least one of the outer chain plates 102 on one side, a support plate 103 is provided, bent outwards at a right angle. A nut 104 is riveted to the support plate 103, with the outer side of the nut 104 flush with the support plate 103. Compared to traditional tapping and welding screws, riveting the nut 104 better ensures the stability of the connection between the support plate 103 and the nut 104, avoiding problems such as thread damage and misalignment of holes. For example, in practical applications, when the chain needs to frequently carry and unload heavy objects, the riveted nut 104 can withstand greater tensile and impact forces, ensuring the reliability of the connection. By fixing the nut 104 to the support plate 103 with its outer side flush with the support plate 103, problems such as insecure tapping and misalignment of holes during screw welding due to the thinness of the support plate 103 are avoided. This greatly improves the stability and installation accuracy of the support plate 103 in fixing the target object, thereby enhancing the reliability of the chain in bearing and fixing objects, which is beneficial to the stable operation of related equipment. Moreover, the nut 104 fixed in the above manner ensures good concentricity between the nut 104 and the mounting hole, preventing deviation.

[0021] As a further improvement, the width of the support plate 103 is no greater than that of the outer chain plate 102. This ensures the stability of the chain during transmission and avoids chain obstruction or wobbling caused by an excessively wide support plate 103. For example, in some transmission systems with limited space, the width of the support plate 103 matches that of the outer chain plate 102, allowing the chain to better adapt to the working environment and operate smoothly. The fact that the width of the support plate 103 is no greater than that of the outer chain plate 102 guarantees the stability of the chain during transmission, enabling it to better adapt to various working environments, reducing operational failures caused by an excessively wide support plate 103, and improving the chain's versatility and applicability.

[0022] In some embodiments of this application, the aforementioned support plate 103 is provided with stepped screw holes, and the end of the nut 104 is provided with a step adapted to the stepped screw holes. The end of the nut 104 is riveted to the stepped screw holes with an interference fit (not shown in the figure). This special fit structure further enhances the firmness of the connection between the nut 104 and the support plate 103, as well as the concentricity of the screw holes and the nut 104. Simultaneously, the interference fit effectively prevents the nut 104 from loosening during use. For example, in working environments with significant vibration, the interference fit of the nut 104 and the stepped screw hole structure ensures the stability of the connection, ensuring that the support plate 103 reliably supports the target object. The riveting and interference fit between the stepped screw holes on the support plate 103 and the steps adapted to the end of the nut 104 greatly enhances the firmness of the connection between the nut 104 and the support plate 103, effectively preventing the nut 104 from loosening. This is particularly suitable for chains used in complex working conditions, ensuring the stable support of the target object by the support plate 103.

[0023] In some embodiments of this application, the edges of the nut 104 are chamfered or rounded. Specifically, chamfered or rounded edges can be set on both the outer and inner edges of the nut 104. This structure can prevent scratches to operators from the edges of the nut 104 during installation and use, and also reduce wear on surrounding components. For example, in scenarios where the chain is frequently operated manually to load and unload objects, the chamfered or rounded edges of the nut 104 can improve the safety and convenience of operation. Setting the edges of the nut 104 to chamfered or rounded improves the safety of operation, reduces the risk of injury to operators, reduces wear on surrounding components, extends the service life of surrounding components, and makes the chain safer and more reliable during use. In addition, the rounded or chamfered edges at the inner edge facilitate the connection between the screw and the nut 104.

[0024] It should be noted that the aforementioned chamfer is also called a bevel, and the R angle (rounded angle) refers to an angle formed by a rounded arc. It is widely used in engineering design and manufacturing. The radius can be set according to actual needs and nut size.

[0025] Furthermore, the support plate 103 and the outer chain plate 102 are integrally formed. This integral structure improves the strength and reliability of the connection between the support plate 103 and the outer chain plate 102, reducing the risk of damage due to weak connection points. For example, in chain applications subjected to high tensile forces, the integrally formed support plate 103 and outer chain plate 102 structure can better withstand tensile forces, ensuring the normal operation of the chain. The integral forming of the support plate 103 and outer chain plate 102 enhances the connection strength, improves the overall reliability of the support plate 103 and outer chain plate 102, and enables them to withstand greater external forces. This is suitable for applications requiring high chain strength and reduces the possibility of chain damage due to problems at the connection points.

[0026] A wear-resistant coating (not shown in the figure) is provided at the connection between the pin 105 and the outer link plate 102 and the inner link 101. This wear-resistant coating effectively reduces friction and wear between the pin 105 and the outer link plate 102 and inner link 101 during long-term use, extending the service life of the pin 105 and thus improving the overall service life and stability of the chain. For example, under prolonged high-load operation, the wear-resistant coating can significantly reduce the wear rate of the pin 105, reducing chain failures caused by pin 105 wear and lowering equipment maintenance costs. The inner link 101 and outer link plate 102 are made of high-strength alloy steel, which greatly improves the overall strength and load-bearing capacity of the chain, enabling it to withstand heavier loads and harsher working environments. For example, in industrial production, when the chain needs to carry heavy items, the high-strength alloy steel chain can reliably complete the task, reducing the risk of chain breakage due to insufficient strength and improving production safety and efficiency.

[0027] Furthermore, the support plate 103 is provided with anti-slip textures. When the target object is placed on the support plate 103, it can increase the friction between the object and the support plate 103, preventing the object from sliding on the support plate 103 and improving the stability of the chain carrying the object. For example, when the chain transports objects with smooth surfaces, the anti-slip textures can effectively prevent the object from slipping, ensuring the safety and reliability of the transportation process.

[0028] like Figure 4 and Figure 5As shown, in some embodiments of this application, a chain with a support plate is also disclosed, comprising: a plurality of inner links 101, each having two sides connected to an outer link plate 102 via pins 105; at least one set of pins 105 extending outward and connected to an outer link plate 102 with a support plate 103; the support plate 103 being bent outward at a right angle relative to the outer link plate 102 on the same side; each set of pins 105 consisting of two adjacent pins 105 between two adjacent outer link plates 102; or each set of pins 105 consisting of two pins 105 at the same position on the same outer link plate 102; a nut 104 being fixedly riveted to the support plate 103; the outer side of the nut 104 being flush with the support plate 103. Compared to the above improvements, in this embodiment, the overall strength of the chain is ensured by installing an outer link plate 102 with a support plate 103 outside one side of the outer link plate 102.

[0029] As an example, for a chain with a support plate, select inner link 101, outer link plate 102, pin 105, support plate 103, and nut 104 that meet the specifications. The inner link 101 and outer link plate 102 are made of high-strength alloy steel to ensure the chain's strength. The pin 105 is passed through the corresponding holes of the inner link 101 and outer link plate 102, connecting them to form the basic framework of the chain. For the outer link plate 102 with the support plate 103, the support plate 103 is bent outward at a right angle and fixed to the corresponding outer link plate 102. The width of the support plate 103 is no greater than that of the outer link plate 102 to ensure the stability of the chain operation. For example, if the width of the outer link plate 102 is 50mm, the width of the support plate 103 can be designed to be 45mm. The nut 104 is then riveted to the support plate 103. The support plate 103 has pre-machined stepped screw holes, and the end of the nut 104 has a step that matches the stepped screw holes. During riveting, ensure that the end of the nut 104 is interference-fitted with the stepped screw holes, so that the nut 104 is firmly fixed to the support plate 103. At the same time, ensure that the outer side of the nut 104 is flush with the support plate 103 to avoid obstruction when installing the target object. At the connection between the pin 105 and the outer link plate 102 and the inner link 101, apply a wear-resistant coating by spraying or other methods to improve the wear resistance of the connection. Finally, machine anti-slip textures on the support plate 103, such as using a knurling process to create diamond-shaped anti-slip textures, to increase the friction of the surface of the support plate 103.

[0030] For example, in an automated material handling system, the chain with a support plate 103 of this invention is used. The chain needs to carry and transport small parts to designated locations for assembly. Because the nuts 104 riveted to the support plate 103 are secure and reliable, during frequent transport, the parts can be firmly fixed to the support plate 103 with bolts, preventing problems such as loose nuts 104 or misaligned holes that could lead to insecure installation or positional deviations. Simultaneously, the anti-slip texture on the support plate 103 further prevents the parts from slipping during transport, ensuring the accuracy and stability of material handling and improving the overall efficiency of the automated production system.

[0031] Based on the same concept, some embodiments of this application also disclose a transmission device, which includes the chain having the above-mentioned support plate 103; a detection sensor or detection device is installed on the support plate 103 of the chain.

[0032] It should be noted that the installation of detection sensors or devices is a conventional technique in this field and will not be elaborated further. Furthermore, the detection and control methods of the sensors are not within the scope of this solution and will not be detailed here. The aforementioned transmission device is a chain drive device, with both the driving and driven devices equipped with sprockets adapted to the chain. There is no standard terminology for the sprockets in the aforementioned chain drive; therefore, they can also be called gears, flywheels, or lower ratchet.

[0033] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.

The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
