Description

Technical Field

[0001] The present invention relates to the technical field of positioning and assembly, and particularly to a modular power output shaft assembly device. Background Art

[0002] The modular power output shaft assembly devices in the prior art are designed specifically for the precise fit between shafts, and are suitable for stably and accurately assembling one shaft into the interior of another shaft. The devices have an automated function, support rapid clamping and disassembly, and are suitable for mass production requirements, and are applicable to high-precision shaft assembly scenarios in industries such as automotive and machinery manufacturing.

[0003] However, the prior art still has the following defects in specific use: 1. The prior art usually requires designing special locking devices for different-sized assembly parts. The locking structures, size specifications, and magnitudes of locking forces required for different-sized shafts are all different, and it is difficult to meet all requirements with a set of general-purpose devices. For example, larger-sized shafts require larger and more robust locking components to provide sufficient clamping force, while smaller-sized shafts require more delicate locking designs to avoid damage. Such locking devices designed for specific sizes greatly increase the R & D, production, and procurement costs of the equipment. Moreover, the coexistence of multiple different specifications of locking devices significantly increases the difficulty of equipment maintenance. Maintenance personnel need to be familiar with the structures and maintenance points of multiple different devices. Once a failure occurs, it takes a long time and effort to find suitable spare parts and perform precise repairs, resulting in an extended downtime of the equipment and seriously affecting production efficiency.

[0004] 2. In the prior art, the methods of sequential locking or asynchronous locking are mostly adopted. It is very difficult to perform precise locking operations on different-sized shafts simultaneously with this method. During sequential locking, the shaft locked first may shift in position due to the external force generated during the subsequent locking of another shaft. Asynchronous locking also causes similar problems. For example, the time difference in locking may cause the shafts to be fixed before their relative positions are completely accurately aligned, ultimately resulting in a position deviation of the shafts after assembly. Such a position deviation will seriously affect the performance of the power output shaft, such as causing vibration and noise during operation, reducing the transmission efficiency, and even accelerating the wear of the shafts and related components, significantly shortening the service life of the equipment.

[0005] Therefore, in view of this, the present invention proposes a modular power output shaft assembly device to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a modular power output shaft assembly device to solve the technical problems raised in the above background art.

[0007] To achieve the above object, the technical solution adopted by the present invention is: a modular power output shaft assembly device for assembling a housing bushing and an assembled shaft body, including an assembly workbench, above which a multi-functional modular mechanism is provided, and the multi-functional modular mechanism is used for accurately assembling the housing bushing and the assembled shaft body and detecting the finished product after assembly.

[0008] Further, the multi-functional modular mechanism includes a micro motor installed inside the assembly workbench, a transmission component is installed outside the micro motor, linkage turntables are symmetrically installed above the transmission component, limit frames are symmetrically installed above the assembly workbench, and a bushing lock and a shaft body lock are respectively installed inside the limit frames.

[0009] Further, a driving cylinder is installed above the assembly workbench, the output shaft end of the driving cylinder is in contact with the side wall of the assembled shaft body, and both the driving cylinder and the micro motor are electrically controlled by an external controller.

[0010] By adopting the above technical solution, the output shaft of the driving cylinder starts to push the assembled shaft body, causing it to move towards the housing bushing.

[0011] Further, the assembly workbench is divided into a left end and a right end as a whole. The housing bushing is located at the left end of the assembly workbench, and the assembled shaft body is located at the right end of the assembly workbench. During the assembly process, the assembled shaft body moves towards the housing bushing by the push of the output shaft of the driving cylinder. According to the movement states of the housing bushing and the assembled shaft body during the assembly process, the left end of the assembly workbench is set as a fixed end, and the right end of the assembly workbench is set as a mobile end.

[0012] By adopting the above technical solution, an assembly method with one end moving and the other end fixed is adopted, which is convenient for positioning and operation, and ensures the assembly accuracy and stability.

[0013] Further, both the bushing lock and the shaft body lock are slidably connected to the limit frame. The bushing lock is located at the fixed end of the driving cylinder, and the shaft body lock is located at the mobile end of the driving cylinder. According to the outer wall size characteristics of the housing bushing and the assembled shaft body and the movement characteristics of the housing bushing and the assembled shaft body, the inner side wall of the bushing lock is set to be arc-shaped, and the inner side wall of the shaft body lock is set to be rectangular.

[0014] By adopting the above technical solution, the equipment cost and maintenance difficulty are reduced, and the versatility of the equipment is improved.

[0015] Further, the transmission assembly as a whole is composed of three pulleys and a belt. The radius of the pulleys in the transmission assembly gradually decreases from the left end to the right end. The pulley in the middle of the transmission assembly is fixedly connected to the output shaft end of the micro motor, and the pulleys at the left and right ends of the transmission assembly are both fixedly connected to the linkage turntable.

[0016] By adopting the above technical solution, the assembly of the fixed end and the mobile end is locked simultaneously, avoiding the position deviation caused by locking successively or out of sync.

[0017] Further, the linkage turntable is in transmission connection with the output shaft of the micro motor through the transmission assembly. When the output shaft end of the micro motor rotates, the linkage turntables at both left and right ends rotate synchronously.

[0018] Further, the linkage turntable is rotatably connected to the limit frame. Arc groove groups are provided on the surface of the linkage turntable. Connecting shafts are slidably connected to the inner walls of the arc groove groups, and the connecting shafts are fixedly connected to the sleeve lock and the shaft body lock respectively.

[0019] Further, a ball component is installed on the inner side wall of the sleeve lock. The ball component is composed of a plurality of spheres, and the spheres in the ball component are all movably connected to the ball component.

[0020] By adopting the above technical solution, the resistance during rotation is small, which is convenient for simulating the actual operation of the shaft body after assembly.

[0021] Further, adjusting shafts are symmetrically and slidably connected to the inner side wall of the shaft body lock. A slide plate frame is fixedly connected to the side of the adjusting shaft away from the shaft body lock. The slide plate frame is slidably connected to the upper surface of the limit frame, and springs are sleeved on the outer walls of the adjusting shafts.

[0022] By adopting the above technical solution, an appropriate compressive force is provided for locking and assembling the shaft body to adjust the position.

[0023] Further, it is characterized in that: a support sleeve ring is movably connected to the upper surface of the assembly workbench. A semi-empty groove is provided on the inner side wall of the support sleeve ring, and a ball sleeve ring is movably connected to the side wall of the support sleeve ring. The support sleeve ring is located at the central position of the accommodating sleeve and the assembling shaft body. In the initial state, the accommodating sleeve fits against the side wall of the support sleeve ring, and the assembling shaft body fits against the side wall of the semi-empty groove.

[0024] Compared with the prior art, the beneficial effects of the present invention are: By introducing a multi-functional modular mechanism, this device can more closely adapt to the embedded assembly process between the receiving bushing and the assembled shaft body. First of all, this device does not need to design a special locking device or perform complex adjustments for assembled parts of different sizes, thereby reducing equipment costs and maintenance difficulties and improving the versatility of the equipment. Secondly, by relying on the self-locking method, it can ensure that during the assembly process, receiving bushings and assembled shaft bodies of different sizes can be accurately positioned and fixed, avoiding position deviations caused by sequential or asynchronous locking, thus ensuring the accuracy and quality of the assembly. Compared with the prior art, this device does not need to perform separate locking operations on components of different sizes, reducing the operation steps and time, improving the assembly efficiency, and thus enabling fast and efficient shaft assembly to meet the needs of mass production.

[0025] Particularly importantly, according to the different motion states of the assembled parts, this device differentiates and designs the shapes of the latches. Specifically, the shaft bushing latch with a fixed-end arc shape perfectly fits the outer wall of the receiving bushing, providing a larger contact area and a more uniform locking force, ensuring that the receiving bushing remains stable during the assembly process without shaking or displacement, guaranteeing the assembly quality. And the gap formed between the inner rectangle of the shaft body latch at the mobile end and the assembled shaft body not only meets the movement requirements of the assembled shaft body during the assembly process but also provides it with a certain amount of slight displacement space, avoiding assembly difficulties caused by rigid connection. At the same time, it can also adapt to the minor deviations of the assembled shaft body during movement, improving the flexibility and reliability of the assembly. Among them, the shaft body latch with a rectangular inner wall provides an accurate guiding function for the assembled shaft body, enabling the assembled shaft body to move smoothly along the outer wall of the rectangular groove during the locking process, ensuring that it accurately maintains the same center position as the receiving bushing at the fixed end. Through this guiding design, the assembled shaft body can quickly and smoothly move to the predetermined position, reducing the assembly time and improving the production efficiency.

[0026] The support collar is located at the center of the receiving bushing and the assembled shaft body. On the one hand, it provides stable support for the movement of the shaft body during the assembly process, reducing the shaking and vibration of the shaft body and ensuring the smooth progress of the assembly process. On the other hand, a cleaning pad can be flexibly installed at the half-empty groove position of the support collar, which can automatically clean the outer wall of the assembled shaft body during its movement, removing impurities and oil stains on key parts such as the shaft channel and the outer wall, ensuring the cleanliness of the shaft body, and being beneficial to improving the service life and performance of the shaft body.

[0027] After assembly, the assembled receiving bushing and the assembled shaft body can be regarded as a whole. The smooth outer wall positions at both ends of this whole are in contact with the spherical balls. Workers can easily manually rotate the assembled whole to conduct no-load running tests to detect problems such as assembly deviations, and can repair or adjust in time to ensure the final performance and quality of the product. This helps to detect potential quality hazards of the product in advance, avoid sending defective products to the next process or delivering them to customers, thereby reducing production costs and improving product quality.

[0028] This device can be decomposed into multiple relatively independent modules, such as a transmission component, a bushing lock, a shaft body lock, etc. During assembly, each module can be assembled and debugged separately, and then assembled as a whole. This can reduce the complexity during the assembly process. When a certain part of the device fails, only the module with problems needs to be replaced or repaired, rather than disassembling and overhauling the entire device. For receiving bushings and assembled shaft bodies of different sizes, the corresponding sized bushing lock and shaft body lock modules can be replaced without re-designing and manufacturing the entire device.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. It should be noted that the structures and working principles of the above-mentioned assembly workbench 1, driving cylinder 11, receiving bushing 12, assembling shaft body 13 and other devices belong to the prior art and will not be elaborated here.

[0032] Embodiment 1 Please refer to Figures 1 to 3 As shown in the figure, a modular power output shaft assembly device is used for assembling the receiving bushing 12 and the assembling shaft body 13, and includes an assembly workbench 1. A multi-functional modular mechanism 2 is arranged above the assembly workbench 1. The multi-functional modular mechanism 2 is used for accurately assembling the receiving bushing 12 and the assembling shaft body 13 and detecting the assembled finished product. It should be noted that a driving cylinder 11 is installed above the assembly workbench 1. The output shaft end of the driving cylinder 11 is in contact with the side wall of the assembling shaft body 13, and both the driving cylinder 11 and the micro motor 21 are electrically controlled by an external controller.

[0033] Please refer to Figures 2 to 8 As shown in the figure, the multi-functional modular mechanism 2 includes a micro motor 21 installed inside the assembly workbench 1. A transmission component 22 is installed outside the micro motor 21. Linkage turntables 23 are symmetrically installed above the transmission component 22. Limiting frames 26 are symmetrically installed above the assembly workbench 1. A bushing lock 27 and a shaft body lock 29 are respectively installed inside the limiting frames 26. It should be noted that the assembly workbench 1 is divided into a left end and a right end as a whole. The receiving bushing 12 is located at the left end of the assembly workbench 1, and the assembling shaft body 13 is located at the right end of the assembly workbench 1. During the assembly process, the assembling shaft body 13 moves towards the direction of the receiving bushing 12 by the push of the output shaft of the driving cylinder 11. According to the movement states of the receiving bushing 12 and the assembling shaft body 13 during the assembly process, the left end of the assembly workbench 1 is set as a fixed end, and the right end of the assembly workbench 1 is set as a movable end. Both the bushing lock 27 and the shaft body lock 29 are slidably connected to the limiting frame 26. The bushing lock 27 is located at the fixed end of the driving cylinder 11, and the shaft body lock 29 is located at the movable end of the driving cylinder 11. And according to the outer wall size characteristics of the receiving bushing 12 and the assembling shaft body 13 and the movement characteristics of the receiving bushing 12 and the assembling shaft body 13, the inner side wall of the bushing lock 27 is set to be arc-shaped, and the inner side wall of the shaft body lock 29 is set to be rectangular. The transmission assembly 22 is integrally composed of three pulleys and a belt. The radius dimensions of the pulleys in the transmission assembly 22 gradually decrease from the left end to the right end. The pulley located in the middle of the transmission assembly 22 is fixedly connected to the output shaft end of the micro motor 21. The pulleys located at the left and right ends of the transmission assembly 22 are both fixedly connected to the linkage turntable 23. The linkage turntable 23 is in transmission connection with the output shaft of the micro motor 21 through the transmission assembly 22. When the output shaft end of the micro motor 21 rotates, the linkage turntables 23 at both ends rotate synchronously. The linkage turntable 23 is rotatably connected to the limiting frame 26. Arc groove groups 24 are provided on the surfaces of the linkage turntables 23. Connecting shafts 25 are slidably connected to the inner walls of the arc groove groups 24. The connecting shafts 25 are both fixedly connected to the bushing lock 27 and the shaft body lock 29. A ball member 28 is installed on the inner side wall of the bushing lock 27. The ball member 28 is composed of a plurality of spherical balls, and the spherical balls in the ball member 28 are all movably connected to the ball member 28. Adjusting shafts 211 are symmetrically and slidably connected to the inner side wall of the shaft body lock 29. A slide plate frame 210 is fixedly connected to the side of the adjusting shaft 211 away from the shaft body lock 29. The slide plate frame 210 is slidably connected to the upper surface of the limiting frame 26. Springs 212 are sleeved on the outer walls of the adjusting shafts 211.

[0034] Specifically, in the preparation stage: as Figure 1 and Figure 2 shown, the staff places the receiving bushing 12 at the fixed end of the left end of the assembly workbench 1, and places the assembling shaft body 13 at the movable end of the right end. At this time, the driving cylinder 11 is in the initial state. The bushing lock 27 and the shaft body lock 29 are respectively located at the corresponding positions in the limiting frame 26. The adjusting shaft 211 on the inner side wall of the shaft body lock 29 is in a relatively extended state under the action of the spring 212, and the slide plate frame 210 is stable at the upper surface position of the limiting frame 26, preparing for the subsequent assembly; When the external controller sends an instruction, the driving cylinder 11 and the micro motor 21 are started successively. Specifically, as Figure 4As shown, the output shaft of the micro motor 21 starts to rotate first, driving the pulley located in the middle of the transmission assembly 22 that is fixedly connected to it. Due to the transmission effect of the belt and the characteristic that the radius of the pulley in the transmission assembly 12 gradually decreases from the left end to the right end, the pulleys fixedly connected to the linkage turntables 23 at both left and right ends rotate synchronously, thereby driving the linkage turntables 23 at both left and right ends to rotate synchronously; As Figure 5 and Figure 6 shown, although the linkage turntables 23 are distributed at the fixed end and the mobile end of the assembly workbench, there are a bushing lock 27 and a shaft body lock 29 corresponding to the upper parts of the linkage turntables respectively. During the rotation of the linkage turntables 23, the arc groove groups formed on their surfaces will continuously squeeze the connecting shaft 25. Since the connecting shaft 25 is fixedly connected to the bushing lock 27 and the shaft body lock 29 respectively, with the rotation of the linkage turntables 23, the bushing lock 27 and the shaft body lock 29 are driven to slide towards each other along their respective tracks within the limit frame 26. During this process, the inner arc side wall of the bushing lock 27 fits against the outer wall of the receiving bushing 12, and the inner rectangular side wall of the shaft body lock 29 approaches the assembled shaft body 13. During the process of the shaft body lock 29 approaching the assembled shaft body 13, if the position of the assembled shaft body 13 is slightly deviated, the adjusting shaft 211 can be compressed under the action of the spring 212, enabling the shaft body lock 29 to better adapt to the position of the assembled shaft body 13 and complete the locking. Finally, through the opposite sliding of the bushing lock 27 and the shaft body lock 29, the synchronous locking of the receiving bushing 12 and the assembled shaft body 13 is achieved simultaneously.

[0035] It should be noted that, please refer to Figures 8 to 10 shown, a support collar 213 is movably connected to the upper surface of the assembly workbench 1. A semi-empty groove 214 is formed on the inner side wall of the support collar 213, and a ball collar 215 is movably connected to the side wall of the support collar 213. The support collar 213 is located at the central position of the receiving bushing 12 and the assembled shaft body 13. In the initial state, the receiving bushing 12 fits against the side wall of the support collar 213, and the assembled shaft body 13 fits against the side wall of the semi-empty groove 214.

[0036] Specifically, after the locking process is completed, the driving cylinder 11 starts to operate. Specifically, the output shaft of the driving cylinder 11 starts to push the assembled shaft body 13, causing it to move towards the receiving bushing 12. When the assembly is completed, at this time, the receiving bushing 12 and the assembled shaft body 13 can seemingly form a whole, as Figure 8 and Figure 9As shown, both ends of the integrated housing sleeve 12 and assembled shaft body 13 are in contact with the ball member 28 on the inner side wall of the bushing latch 27 and the ball collar 215 respectively. At this time, the operator can manually rotate this whole for no-load running test. Since the spherical ball in the ball member 28 is movably connected to the ball member, the resistance during rotation is small, which is convenient for simulating the actual operation of the shaft body. By detecting whether there are abnormal vibrations, noises, etc., it is possible to judge whether there are problems such as assembly deviations. If problems are found, the equipment or assembly process can be repaired or adjusted in time to ensure the final performance and quality of the product.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
