Description

Load-bearing connection structure for tools and equipment Technical Field

[0001] This invention relates to a connection structure for a tool or equipment, particularly a load-bearing connection structure disposed between a power source and a working end device, capable of receiving and guiding the axial load generated by the working end device during operation, and enabling the power source to primarily bear the rotational output load. It is applicable to power transmission applications of various mechanical tools and equipment. Prior Technology

[0002] In existing power transmission structures for tools and equipment, to improve the compatibility and ease of installation of different working modules, adapter plates or interface conversion structures are often installed between the power source and the working end equipment. This allows for quick assembly and disassembly of hand tools or working modules, while maintaining axial alignment and assembly stability during power transmission. These adapter structures, often using fixing plates, guiding structures, or interface conversion components, provide rapid assembly and stable transmission, effectively improving installation efficiency and operational flexibility.

[0003] However, the design of the aforementioned transition structures focuses primarily on the transmission of rotary power, assembly alignment, and ease of operation. They typically lack a dedicated load-bearing structure to support and guide the axial thrust generated by the working end equipment during operation. When such transition structures are applied to hydraulic cylinders, pneumatic cylinders, or other working end equipment with a pushing action, the axial thrust generated during operation often returns to the power source along the coupling or drive shaft. This forces the power source to bear not only the rotary output load but also the additional axial load, leading to transmission problems, increased energy loss, and even affecting the durability of the power source.

[0004] Existing technologies address the aforementioned problems by increasing the specifications of the power source, improving the strength of transmission components, or adding a speed reducer. However, these approaches not only increase the size and cost of the equipment but also fail to provide an effective axial load-bearing configuration for the transition structure itself, leaving room for structural improvement. Summary of the Invention

[0005] The main objective of this invention is to provide a load-bearing connection structure for tool equipment. By providing a load-bearing seat on the front sleeve plate, the axial thrust generated by the working end equipment during operation can be received and guided to the body structure of the tool equipment, preventing the axial load from being transmitted back to the power source, so that the power source mainly bears the rotational output load.

[0006] To achieve the above objectives, the present invention includes a front sleeve plate and a rear sleeve plate, wherein the front sleeve plate is used to connect the working end device and the rear sleeve plate is used to connect the power source, and the front sleeve plate and the rear sleeve plate cooperate with each other to enable the working end device and the power source to form a power connection; a coupling member is provided between the front sleeve plate and the rear sleeve plate to transmit the rotational output of the power source to the working end device, and a bearing seat is provided in the central region of the front sleeve plate, the bearing seat including a plurality of support arms extending from the outside to the center and converging in the center, and a bearing receiving part is formed in the center of the support arms to receive at least one bearing.

[0007] With the aforementioned structural configuration, the axial thrust generated by the working end equipment during operation can be introduced into the bearing seat through the coupling component, and the bearing seat supports the body structure of the rear guide tool equipment, avoiding the power source from bearing the axial load generated by the working end equipment, thereby improving the stability of power transmission and the overall reliability of use.

[0008] In one embodiment of this invention, the bearing seat system is integrally formed with the front sleeve plate; in another embodiment, the bearing seat system is detachably mounted on the front sleeve plate; and in other embodiments, the support arm may be arranged in a cross shape or in three or more radial arrangements, and cooperate with the bearing housing to limit the bearing's position in the axial and radial directions.

[0009] Compared to existing adapter structures that only focus on power transmission and installation alignment, this new load-bearing connection structure, by setting a load-bearing seat on the front sleeve plate, allows the axial thrust generated by the working end equipment during operation to be received at the connection structure and guided to the machine body structure of the tool equipment, thus preventing the axial load from being transmitted back to the power source and reducing the unnecessary load on the power source during operation.

[0010] Therefore, this new invention allows the power source to primarily bear the rotational output load, which helps improve the stability of power transmission, reduces transmission disruptions and energy loss caused by axial loads, and helps extend the service life of the power source and related transmission components.

[0011] Furthermore, the load-bearing seat of this new type is formed in the middle area of ​​the front sleeve plate, and through the configuration of the arm assembly and bearing housing, it provides a stable load-bearing and positioning effect, so that the load-bearing structure can be integrated with the original transfer and transmission configuration without the need to add a large reducer or increase the power source specifications. It has the advantages of simplified structural configuration, no increase in equipment size and controllable cost.

[0012] Furthermore, the load-bearing seat of this new type can be designed as an integral or detachable structure according to actual needs, and can be adjusted to match different support arm configurations and coupling component types. It has good design flexibility and application adaptability, and is suitable for power connection occasions of various tools, equipment and working end modules. Simple Explanation of the Diagram

Figure 4 is an exploded view from the other side of Figure 3. Figure 5 is a cross-sectional view of the present invention in use. Figure 6 is a perspective view of one embodiment of the helical gear coupling of this novel invention.

[0014] As shown in Figure 1, the load-bearing connection structure 1 of this novel tool and equipment is disposed between a power source 50 and a working end device 60, so as to transmit the rotational output of the power source 50 to the working end device 60.

[0015] As shown in Figures 1 and 2, this new type includes a front sleeve plate 10, a rear sleeve plate 20, and a coupling component 30 (as shown in Figure 3). The front sleeve plate 10 is used to connect the working end device 60, and the rear sleeve plate 20 is used to connect the power source 50. The front sleeve plate 10 and the rear sleeve plate 20 cooperate with each other so that the working end device 60 and the power source 50 can be connected by the load-bearing connection structure 1.

[0016] As shown in Figure 3, the coupling component 30 is disposed between the front sleeve plate 10 and the rear sleeve plate 20 to transmit the rotational output of the power source 50 to the working end device 60 (as shown in Figures 1 and 2). In this embodiment, the coupling component 30 may be a coupling, but is not limited thereto.

[0017] As shown in Figures 3 and 4, the front sleeve plate 10 has a bearing seat 40 in its central region. The bearing seat 40 includes a plurality of support arms 41 extending from the outer side to the center. These support arms 41 converge at the center and form a recessed socket structure to form a bearing housing 42. A bearing 43 is housed in the bearing housing 42 to restrict the bearing 43's axial and radial position.

[0018] In one embodiment, the support seat 40 is integrally formed with the front sleeve plate 10; in another embodiment, the support seat 40 may also be detachably mounted on the front sleeve plate 10. Furthermore, the support arms 41 may be arranged in a cross shape or in a radial arrangement of three or more, but none of these arrangements affect the load-bearing function of the support seat 40.

[0019] As shown in Figure 5, when the working end device 60 is in use and generates an axial backward thrust, the axial backward thrust acts backward along the transmission path of the coupling member 30.

[0020] By means of the bearing seat 40 provided in the middle of the front sleeve plate 10, the axial backward thrust is received by the bearing seat 40 before reaching the power source 50, and is guided by the bearing seat 40 to the machine body structure of the tool and equipment, instead of being transmitted back to the spindle of the power source 50 along the transmission path.

[0021] Therefore, the power source 50 mainly bears the load required for rotational output during operation, and does not bear the axial thrust generated by the working end device 60.

[0022] As shown in Figures 6 and 7, in one embodiment, the coupling member 30 can be a helical gear coupling. Its helical gear structure uses the gradual meshing of the tooth surfaces to cooperate with the output shaft 61 to transmit rotational output, making the rotational transmission process more continuous. However, the specific tooth shape and size configuration of the helical gear can be adjusted according to actual needs and is not limited to those shown in the figures.

[0023] In addition, the power source 50 can be an electric motor, and the working end device 60 can be a hydraulic cylinder, pneumatic cylinder or other mechanical action device, all of which are applicable to this new structure.

[0024] In summary, the load-bearing connection structure 1 for tools and equipment of this invention has the following advantages and effects:

[0025] 1. Effective separation of rotational load and axial load: Due to the bearing seat 40 set in the middle of the front sleeve plate 10, the axial thrust generated by the working end device 60 during operation can be received and guided to the machine structure of the tool before reaching the power source 50, thus preventing the axial load from being transmitted back to the power source 50 through the coupling component 30, so that the power source 50 mainly bears the load required for rotational output.

[0026] 2. Reduce unnecessary loads on the power source during operation: Since the axial thrust no longer acts on the spindle of the power source 50, the load-bearing connection structure 1 can reduce the non-rotational load on the power source 50 during operation, which helps to improve the stability of the overall operating conditions.

[0027] 3. Improve the stability of power transmission: Through the structural configuration of the bearing seat 40, the force state in the transmission path tends to be simple, and the rotational output transmission through the coupling component 30 can be kept stable, which helps to reduce the instability of operation caused by load interference.

[0028] 4. Facilitates flexible configuration of power source specifications: Since the power source 50 mainly bears the rotational output load during operation, it has a high degree of flexibility in specification selection in practical applications, allowing the appropriate power source 50 to be selected according to the needs of the tools and equipment, without being limited by axial thrust.

[0029] 5. The structural configuration is hidden inside the machine body and does not affect the appearance and size: The load-bearing seat 40 and the coupling component 30 are configured between the front sleeve plate 10 and the rear sleeve plate 20. The overall load-bearing connection structure 1 can be hidden inside the tool and equipment without increasing the appearance size of the equipment or affecting the configuration space of the existing equipment.

[0030] 6. Wide range of applications and high application flexibility: The load-bearing connection structure 1 of this new type can be used with an electric motor as a power source 50 and with the working end equipment 60 as various tools and equipment such as hydraulic cylinders, pneumatic cylinders or other mechanical devices, which has good industrial application flexibility.
