Description

Technical Field

[0001] This application relates to the field of mechanical component assembly and welding technology, and in particular to an automatic assembly and welding machine for drive spindle components. Background Technology

[0002] A drive spindle is a key component in power systems or assemblies used in mechanical engineering, manufacturing, and automation to drive the rotation of mechanical equipment. The drive spindle typically receives energy from a motor or other power source and converts it into rotational motion. This rotational motion is then transmitted to the spindle, driving the components attached to it to rotate. The drive spindle is one of the critical components in mechanical equipment; its performance and quality directly affect the machining accuracy, production efficiency, and reliability of the entire machine. Furthermore, other components are usually assembled on the drive spindle, and their assembly accuracy is also crucial to the effective driving quality of the drive spindle.

[0003] As per the instruction manual Figure 1-2 The diagram illustrates a drive spindle structure, including a spindle, sprockets symmetrically mounted on both sides of the spindle, and chain teeth positioned near one side. After assembling the spindle into the equipment, other accessories still need to be connected to the sprockets. Therefore, the assembly precision between the sprockets and the spindle directly affects the quality of the active drive and the transmission effect of the sprockets. Currently, the most convenient assembly method is to first mount the sprockets onto the spindle at the designed position, then fix them by electric welding, and finally achieve a stronger connection between the sprockets and the spindle through full welding.

[0004] However, due to the fitting gap between the sprocket and the spindle, and the smooth surface of the spindle, there are currently issues such as... after fitting the sprocket onto the spindle. Figure 4 The axial deflection shown, and as Figure 5 The axial displacement shown, even when measured with a right-angle ruler and measuring ruler to check the perpendicularity and positioning of the chain, will still cause a certain axial skew and displacement deviation of the chain relative to the spindle due to observation errors, affecting the driving effect of the chain and spindle in the later stage. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide an integrated automatic assembly and welding machine for drive spindle components, which can not only effectively improve the assembly accuracy and efficiency of the sprocket and spindle, but also improve the efficiency of subsequent welding operations.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: an automatic assembly and welding machine for a drive spindle assembly, the spindle assembly including a spindle and chain discs symmetrically sleeved on both sides of the spindle, characterized in that: the automatic assembly and welding machine includes an assembly component and a welding component, the assembly component can be moved to the welding component, and the assembly component synchronously positions the spindle and the chain discs.

[0007] Preferably, the assembly component includes chain disk positioning bodies spaced at intervals, each chain disk positioning body having an embedding groove for embedding the chain disk, and clamping cylinders spaced at intervals along the circumference of the chain disk positioning body, which synchronously abut against the circumferential surface of the chain disk.

[0008] Preferably, a V-shaped groove is provided at the end of each of the clamping cylinders 4.

[0009] Preferably, each of the chain track positioning bodies has an opening in the middle through which the main shaft passes, and support rollers supporting the main shaft and the chain track are provided on both sides of the opening.

[0010] The beneficial effects of this application are: the assembly and welding integrated machine assembles the spindle and sprocket and achieves relative positioning through the assembly components, and the welding operation can be completed quickly through the welding components. Thus, the integrated machine can not only effectively improve the assembly accuracy and efficiency of the sprocket and spindle, but also improve the efficiency of subsequent welding operations.

[0025] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] See attached document Figures 1-12 The diagram shows an automatic assembly and welding machine for a drive spindle assembly. The spindle assembly includes a spindle 1 and sprockets 2 symmetrically mounted on both sides of the spindle 1. Figure 1-2 As shown, after the chain disc 2 and chain teeth are fitted onto the main shaft, the relative positioning of the chain disc 2 and chain teeth with the main shaft is ensured by measuring and observing with a right-angle ruler and a measuring ruler (the measuring ruler is not shown in the figure). Then, electric welding and full welding reinforcement are used to complete the assembly and welding of the drive main shaft assembly.

[0027] To address the issue of assembly errors affecting the subsequent driving performance of the spindle and sprocket due to manual assembly and measurement, this application provides an automatic assembly and welding integrated machine, which includes assembly components and welding components. The assembly components are used to assemble the spindle 1 and the sprocket 2 (this application describes the sprocket 2 and the spindle 1 as being assembled in the same way as the sprocket 2) and achieve relative positioning. The welding components are used to fasten the connection between the sprocket 2 and the spindle 1 after assembly.

[0028] To avoid obstruction during assembly, such as... Figure 11-12As shown, the assembly component can be moved to the welding component. That is, when assembling the main shaft 1 and the chain 2 through the assembly component, the assembly component is moved to the outside of the welding component. After the chain 2 and the main shaft 1 are assembled on the assembly component, the whole assembly is moved to the welding component for welding. Thus, this integrated machine can not only effectively improve the assembly accuracy and efficiency of the chain 2 and the main shaft, but also improve the efficiency of subsequent welding operations.

[0029] Specifically, such as Figure 6 As shown, the assembly includes chain track positioning bodies 3 spaced apart, each with an embedding groove 3a for embedding the chain track 2. Each chain track positioning body 3 is preferably welded together from steel plates at intervals, with the symmetrical steel plates forming the embedding groove 3a for the chain track 2. Clamping cylinders 4 are spaced circumferentially on the chain track positioning bodies 3, synchronously abutting against the circumferential surface of the chain track 2. Similarly, each clamping cylinder 4 is located between the spaced steel plates. During operation, the chain track 2 is embedded into the embedding groove 3a, and then the clamping cylinders 4 are driven to move synchronously, simultaneously abutting against the circumferential surface of the chain track 2. This ensures the consistency of the axis of the chain track 2 after clamping.

[0030] To further improve the stability of the clamping cylinder 4 against the circumference of the chain disc 2, and to avoid the problem of axial misalignment of the chain disc 2, such as Figure 8 As shown, preferably, a V-shaped groove 4a is provided at the end of each clamping cylinder 4. When clamping the chain disc 2, the side of the chain disc 2 is embedded into the V-shaped groove 4a of each clamping cylinder 4, thereby limiting the axial deviation of the chain disc 2 after clamping. Furthermore, because the inner width of the V-shaped groove 4a gradually decreases from the outside to the inside, both side walls can contact the chain disc 2, thus effectively avoiding the inaccurate positioning caused by the embedding gap between the chain disc 2 and the inner wall of the rectangular groove compared to a rectangular groove.

[0031] After the chainring 2 is clamped and positioned as described above, to facilitate the assembly of the spindle 1, as follows: Figure 6-7 As shown, each of the chain disc positioning bodies 3 has an opening 3b in the middle for the main shaft 1 to pass through, and support rollers 5 are provided on both sides of the opening 3b to support the main shaft 1 and the chain disc 2 coaxially. After the chain disc 2 is clamped and positioned, one end of the main shaft 1 is supported on the outer support roller 5, and then the main shaft 1 is driven to move on the support roller 5, and then passes through the chain discs 2 at intervals to achieve the through-positioning with the chain disc 2.

[0032] Furthermore, if the gap between the center hole of the main shaft 1 and the chain disc 2 is not eliminated, preferably as follows: Figure 9As shown, the device includes a positioning sleeve 6 fitted onto the end of the main shaft 1. The front end face of the positioning sleeve 6 is configured as a first inclined surface 61 that can contact the center hole of the chain disc 2, and a second inclined surface 62 that contacts the end of the main shaft 1. In use, the positioning sleeve 6 is fitted onto the end of the main shaft 1, so that the second inclined surface 62 makes circumferential contact with the end of the main shaft 1, achieving coaxiality with the main shaft 1. Then, the main shaft 1 is pushed towards the chain disc 2, causing the first inclined surface 61 to make circumferential contact with the center hole of the chain disc 2. That is, the positioning sleeve eliminates the fitting gap between the chain disc 2 and the main shaft 1, achieving coaxiality between the two. The length of the positioning sleeve 6 can determine the designed position of the chain disc 2 on the main shaft 1. At the same time, using the positioning sleeve 6 between the main shaft 1 and the chain disc 2 on the other side can further improve the positioning accuracy of the main shaft 1 and the chain disc 2. After the chain disc 2 and the inner side of the main shaft 1 are joined by welding components, the positioning sleeve 6 is removed, and the two sides of the chain disc 2 can be fully welded.

[0033] Preferred, such as Figure 11-12 As shown, the welding component is a welding robot 7 set on one side of the assembly component, and a drive guide rail 8 is set at the bottom of the assembly component. After the chain disk 2 and the main shaft 1 are positioned and assembled, the entire assembly is moved to the welding robot 7 by the drive guide rail 8 to perform a full welding operation.

[0034] The principle of this application is as follows: During operation, the chain disc 2 is embedded into the embedding groove 3a, and then the clamping cylinder 4 is driven to move synchronously, so that the chain disc 2 is positioned and embedded into the V-shaped groove 4a. Then, one end of the main shaft 1 is supported on the outer support roller 5, and the main shaft 1 is driven to move on the support roller 5, and then passes through the chain discs 2 with the spacing set. Then, the assembly component is driven to move as a whole on the drive guide rail 8 to the welding component. Then, the positioning sleeves 6 are put into both ends of the main shaft 1 to eliminate the gap between the center hole of the main shaft 1 and the chain disc 2, and at the same time, the position of the chain disc 2 on the main shaft 1 is further determined. Then, the inner joint of the chain disc 2 and the main shaft 1 is welded by the welding robot 7. After that, the positioning sleeves 6 are removed to complete the full welding operation. After the welding is completed, the main shaft 1 and the chain disc 2 are removed upward from the embedding groove 3a of the chain disc positioning body 3 and disassembled, while the assembly component is reset to wait for the next assembly.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
