Description

Technical Field

[0001] This utility model belongs to the technical field of cotter pin press-fit auxiliary equipment, specifically relating to a modular cotter pin press-fit device. Background Technology

[0002] As a core component of the engine, the turbine housing requires cotter pins to be press-fitted at critical locations in the rotating shaft system during assembly to prevent loosening of the connectors under high-speed conditions. These pins are typically located in precision areas such as the turbine bearing housing and regulating valve connecting rods, and must simultaneously meet the dual requirements of anti-loosening reliability and assembly consistency. Especially with the development of turbocharging technology towards higher power density, the number of cotter pin press-fitting points required for a single turbine assembly can reach 3-5, becoming a necessary process on the final assembly line.

[0003] Currently, this process is largely manual, requiring workers to use needle-nose pliers to hold the cotter pin, manually align it with the pin hole, and then hammer it in. However, in practice, the pin is prone to slipping, the hammering force is inconsistent, and the pin is easily bent, often requiring rework. Furthermore, the pressing operation space is limited, making it inconvenient to operate and resulting in low pressing efficiency. In addition, when dealing with various types of turbine components, frequent tooling adjustments are required, leading to long downtime during product changeovers, which severely restricts production line efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to improve the pressing efficiency of cotter pins. In view of the shortcomings of the prior art, a modular cotter pin pressing device is provided.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model provides a modular cotter pin pressing device, including a mounting platform, an axial positioning mechanism, a lateral positioning mechanism, a support frame, cotter pin pressing components, and a quick-change plate. Both the mounting platform and the support frame are detachably mounted on the quick-change plate. The axial positioning mechanism and the lateral positioning mechanism are both mounted on the mounting platform. The axial positioning mechanism is used for coaxially mounting and fixing the volute assembly, and the lateral positioning mechanism is used for clamping the outer wall of the volute assembly. Multiple cotter pin pressing components are provided, all mounted on the support frame. Each cotter pin pressing component is used to clamp a cotter pin and drive the cotter pin to move toward or away from the corresponding cotter pin pressing point on the volute assembly.

[0006] Compared to existing technologies, the advantages of this utility model include: a modular cotter pin pressing device consisting of a mounting platform, an axial positioning mechanism, a lateral positioning mechanism, a support frame, a cotter pin pressing assembly, and a quick-change plate. Both the axial and lateral positioning mechanisms are mounted on the mounting platform, ensuring structural stability through the support of the platform. The axial positioning mechanism can coaxially mount and fix the volute assembly, thus achieving axial positioning by centrally positioning the volute assembly vertically on it. The lateral positioning mechanism can clamp the outer wall of the volute assembly, thereby restricting its circumferential movement and preventing axial rotation. This effectively improves the stability of the volute assembly on the mounting platform, ensuring accuracy during cotter pin insertion and improving pressing precision. Furthermore, the cotter pin... The cotter pin pressing assembly consists of multiple units, all mounted on a support frame to ensure installation stability. Each cotter pin pressing assembly can clamp a cotter pin and drive it to move toward or away from the corresponding cotter pin pressing point on the volute assembly. This allows for simultaneous pressing of multiple cotter pins on the volute assembly, effectively improving pressing efficiency. Furthermore, the pressing force applied to the cotter pin by the cotter pin pressing assembly remains stable, preventing slippage or bending and avoiding rework, further enhancing pressing efficiency. In addition, both the support frame and the mounting platform can be detachably mounted on a quick-change plate. The quick-change plate ensures the installation stability of the mounting platform and support frame, and allows for quick loading and unloading of different models of support frames and mounting platforms, facilitating shorter changeover downtime and effectively improving production line efficiency.

[0022] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0023] One embodiment of this utility model provides a modular cotter pin pressing device, including a mounting platform 1, an axial positioning mechanism 2, a lateral positioning mechanism 3, a support frame 4, cotter pin pressing components 5, and a quick-change plate 6. The mounting platform 1 and the support frame 4 are detachably mounted on the quick-change plate 6. The axial positioning mechanism 2 and the lateral positioning mechanism 3 are both mounted on the mounting platform 1. The axial positioning mechanism 2 is used to coaxially mount and fix the volute assembly 7, and the lateral positioning mechanism 3 is used to clamp the outer wall of the volute assembly 7. There are multiple cotter pin pressing components 5, all of which are mounted on the support frame 4. Each cotter pin pressing component 5 is used to clamp the cotter pin and drive the cotter pin to move toward or away from the corresponding cotter pin pressing point on the volute assembly 7.

[0024] Specifically, the cotter pin press assembly 5 can clamp the end of the cotter pin and can be driven by a telescopic motor or telescopic cylinder to move linearly, so that the cotter pin moves back and forth axially, making it easier for the cotter pin to pass into the pin hole.

[0025] In this embodiment, as Figure 1As shown, a modular cotter pin pressing device is constructed from a mounting platform 1, an axial positioning mechanism 2, a lateral positioning mechanism 3, a support frame 4, a cotter pin pressing assembly 5, and a quick-change plate 6. Both the axial positioning mechanism 2 and the lateral positioning mechanism 3 are mounted on the mounting platform 1, ensuring structural stability through the support of the mounting platform 1. The axial positioning mechanism 2 can coaxially mount and fix the volute assembly 7, thereby achieving axial positioning by centrally positioning the volute assembly 7 vertically fixed on the axial positioning mechanism 2. The lateral positioning mechanism 3 can clamp the outer wall of the volute assembly 7, thereby restricting the circumferential movement of the volute assembly 7 and preventing it from rotating around the axial direction. This effectively improves the stability of the volute assembly 7 on the mounting platform 1, ensuring the accuracy of subsequent cotter pin insertion and improving pressing accuracy. Furthermore, the cotter pin pressing assembly 5 has… Multiple cotter pin pressing components 5 are installed on support frame 4 to ensure the installation stability of cotter pin pressing components 5. Each cotter pin pressing component 5 can clamp a cotter pin and drive the cotter pin to move toward or away from the corresponding cotter pin pressing point on the volute assembly 7. This allows for the simultaneous pressing of multiple cotter pins on the volute assembly 7 by multiple cotter pin pressing components 5, effectively improving pressing efficiency. Moreover, the pressing force applied to the cotter pin by the cotter pin pressing components 5 remains stable, preventing the cotter pin from slipping or bending, avoiding rework, and further improving pressing efficiency. In addition, both support frame 4 and mounting platform 1 can be detachably installed on quick-change plate 6. The quick-change plate 6 can ensure the installation stability of mounting platform 1 and support frame 4, and can also enable quick loading and unloading of different models of support frame 4 and mounting platform 1, which can shorten changeover downtime and effectively improve production line efficiency.

[0026] Optionally, the axial positioning mechanism 2 includes a tensioning assembly 21, which includes a tensioning disc 211 and a positioning post 212. The tensioning disc 211 is mounted on the mounting platform 1, and the positioning post 212 is coaxially mounted on the tensioning disc 211 and is used for mounting the volute assembly 7 so that the side wall of the tensioning disc 211 fits against the inner wall of the volute assembly 7. The side wall of the tensioning disc 211 is used to press against the inner wall of the volute assembly 7 to tension the volute assembly 7.

[0027] Specifically, the tensioning disc 211 has a horizontal telescopic structure such as a threaded push rod inside, which can drive the side wall to move closer to or away from the axial center with the axial center as the origin.

[0028] In this optional embodiment, such as Figure 1 and Figure 2As shown, the axial positioning mechanism 2 is equipped with a tensioning component 21, which consists of a tensioning plate 211 and a positioning column 212. The tensioning plate 211 is mounted on the mounting platform 1, and the positioning column 212 is coaxially mounted on the tensioning plate 211. The positioning column 212 can be used to mount the volute assembly 7, which can facilitate quick positioning of the volute assembly 7 during placement and prevent deviation of the placement position. It can also make the side wall of the tensioning plate 211 fit against the inner wall of the volute assembly 7. At this time, the side wall of the tensioning plate 211 can squeeze the inner wall of the volute assembly 7, thereby tightening the volute assembly 7, so that the central axis of the main body of the volute assembly 7 coincides with the central axis of the tensioning plate 211, maintain axial positioning, and ensure the placement stability of the volute assembly 7.

[0029] Optionally, the axial positioning mechanism 2 further includes a clamping assembly 22, which includes a rotating column 221, a telescopic head 222, and a clamping plate 223. The rotating column 221 is mounted on the mounting platform 1 and is located on one side of the tensioning assembly 21. The telescopic head 222 is mounted on the rotating column 221 and is used for vertical extension and retraction. One end of the clamping plate 223 is mounted on the telescopic head 222. The rotating column 221 is used to rotate in the vertical direction to drive the other end of the clamping plate 223 to move above the volute assembly 7, so that the telescopic head 222 can drive the clamping plate 223 to move down and squeeze the volute assembly 7.

[0030] Specifically, the telescopic head 222 is equipped with a spring arranged in the vertical direction.

[0031] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the axial positioning mechanism 2 is also equipped with a clamping assembly 22, which consists of a rotating column 221, a telescopic head 222, and a clamping plate 223. The rotating column 221 is mounted on the mounting platform 1 and is located on one side of the tensioning assembly 21. The telescopic head 222 is mounted on the rotating column 221 and can extend and retract vertically. One end of the clamping plate 223 can be mounted on the telescopic head 222. In this way, the rotating column 221 can rotate vertically, thereby driving the clamping plate 223 to rotate around one end of the telescopic head 222. At this time, the telescopic head 222 extends and retracts vertically to adjust the height of the clamping plate 223, so that the other end of the clamping plate 223 moves to the top of the volute assembly 7. Then, the telescopic head 222 drives the clamping plate 223 to move down and squeeze the volute assembly 7. This achieves the cooperation and limiting of the clamping plate 223 and the mounting platform 1 on the volute assembly 7, preventing the volute assembly 7 from moving up and down, and further ensuring the installation stability of the volute assembly 7.

[0032] Optionally, the lateral positioning mechanism 3 includes an angular positioning post 31, which is mounted on the mounting platform 1 and located on one side of the axial positioning mechanism 2. The angular positioning post 31 is used to fit against the first outer wall of the volute assembly 7.

[0033] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the lateral positioning mechanism 3 is provided with an angular positioning post 31. The angular positioning post 31 is installed on the mounting platform 1 and located on one side of the axial positioning mechanism 2. When the volute assembly 7 is fitted onto the axial positioning mechanism 2, the angular positioning post 31 can fit against the first outer side wall of the volute assembly 7, thereby providing a lateral limit on the volute assembly 7, preventing the volute assembly 7 from shifting laterally, and effectively improving the installation stability of the volute assembly 7.

[0034] Optionally, the lateral positioning mechanism 3 further includes an angular clamping assembly 32, which includes a connecting frame 321 and a rotating block 322. The connecting frame 321 is mounted on the angular positioning post 31 and is arranged intersecting the angular positioning post 31. The rotating block 322 is rotatably mounted on the connecting frame 321 and is used to rotate to approach or move away from the second outer side wall of the volute assembly 7. The second outer side wall and the first outer side wall intersect each other.

[0035] Specifically, an elastic structure, such as a spring, is connected between the connecting frame 321 and the rotating block 322, which can provide elastic force when the rotating block 322 is in contact with the second outer side wall, so that the rotating block 322 abuts against the second outer side wall.

[0036] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the lateral positioning mechanism 3 is also provided with an angular clamping assembly 32. The angular clamping assembly 32 is composed of a connecting frame 321 and a rotating block 322. The connecting frame 321 is mounted on the angular positioning post 31 and is arranged to cross the angular positioning post 31. This allows the end of the connecting frame 321 to extend to the second outer wall of the volute assembly 7, which intersects with the first outer wall. The rotating block 322 is rotatably mounted on the connecting frame 321 and can also rotate to approach or move away from the second outer wall of the volute assembly 7. With this arrangement, when the first outer wall of the volute assembly 7 abuts against the angular positioning post 31, the rotating block 322 can rotate to fit against the second outer wall, and then cooperate with the angular positioning post 31 to clamp the intersecting two side walls of the volute assembly 7, which can easily ensure the lateral positioning stability of the volute assembly 7.

[0037] Optionally, the cotter pin press-fit assembly 5 includes a cotter pin press-fit head 51, a telescopic drive member 52, and a moving track 53. The telescopic drive member 52 and the moving track 53 are mounted on the support frame 4. The cotter pin press-fit head 51 is used to clamp the end of the cotter pin. The cotter pin press-fit head 51 is slidably mounted on the moving track 53 and is detachably driven connected to the telescopic drive member 52. The telescopic drive member 52 is used to drive the cotter pin press-fit head 51 to move along the moving track 53 toward or away from the cotter pin press-fit point.

[0038] Specifically, the telescopic drive component 52 is a telescopic motor or telescopic cylinder, etc.

[0039] In this optional embodiment, such as Figure 1 and Figure 2 As shown, a cotter pin pressing assembly 5 is composed of a cotter pin pressing head 51, a telescopic drive component 52, and a moving track 53. The telescopic drive component 52 and the moving track 53 are mounted on the support frame 4, while the cotter pin pressing head 51 is slidably mounted on the moving track 53 and is detachably driven connected to the telescopic drive component 52. In this way, the telescopic drive component 52 can drive the cotter pin pressing head 51 to move towards or away from the cotter pin pressing point along the moving track 53. At the same time, the cotter pin pressing head 51 can clamp the end of the cotter pin. Thus, under the stable driving force of the telescopic drive component 52, the cotter pin pressing head 51 can accurately and stably press the cotter pin onto the volute assembly 7, avoiding rework and ensuring the pressing efficiency of the cotter pin.

[0040] Optionally, the modular cotter pin pressing device also includes an adjustment component 8, which is mounted on the support frame 4 and drivenly connected to the cotter pin pressing component 5 to drive the cotter pin pressing component 5 to move within the circumferential space of the cotter pin pressing point.

[0041] Specifically, the adjustment component 8 can be a telescopic adjuster or an adjustment pad, etc.

[0042] In this optional embodiment, in order to accommodate the press-fitting of cotter pins at different positions on the volute assembly 7 and the press-fitting of cotter pins on volute assemblies 7 of different sizes, such as Figure 1 and Figure 2 As shown, the modular cotter pin pressing device is also equipped with an adjustment component 8, which is mounted on the support frame 4 and can be driven to connect with the cotter pin pressing component 5. With this configuration, the adjustment component 8 can drive the cotter pin pressing component 5 to move in the circumferential space of the cotter pin pressing point, thereby adjusting the position of the cotter pin pressing component 5 so that it can be accurately aligned with the cotter pin pressing point on the volute assembly 7. This enables the pressing of cotter pins at different positions on the volute assembly 7 as well as the pressing of cotter pins on volute assemblies 7 of different sizes.

[0043] Optionally, the adjustment assembly 8 includes a first adjustment pad 81 and a second adjustment pad 82. The first adjustment pad 81 is detachably connected to the cotter pin press head 51 and the telescopic drive member 52, respectively. The second adjustment pad 82 is connected to the moving rail 53 and the support frame 4, respectively, and is located on one side of the first adjustment pad 81 in the horizontal direction.

[0044] In this optional embodiment, such as Figure 1 and Figure 2As shown, an adjustment assembly 8 is formed by a first adjusting pad 81 and a second adjusting pad 82. The first adjusting pad 81 is detachably connected to the cotter pin press head 51 and the telescopic drive member 52, respectively. This configuration allows the position of the cotter pin press head 51 along the pressing direction to be adjusted by increasing or decreasing the number of the first adjusting pads 81 or by adjusting the size of the first adjusting pads 81. Correspondingly, the second adjusting pad 82 is connected to the moving track 53 and the support frame 4, respectively, and is located on one side of the first adjusting pad 81 along the horizontal direction. This configuration allows the position of the cotter pin press head 51 perpendicular to the pressing direction to be adjusted by increasing or decreasing the number of the second adjusting pads 82 or by adjusting the size of the second adjusting pads 82. This, in conjunction with the adjustment of the first adjusting pad 81, enables flexible adjustment of the position of the cotter pin press head 51 in the space surrounding the cotter pin press point.

[0045] Optionally, the adjustment assembly 8 further includes a third adjustment pad 83, which is connected to the support frame 4 and the second adjustment pad 82 respectively, and is located below the second adjustment pad 82.

[0046] In this optional embodiment, such as Figure 1 and Figure 2 As shown, the adjustment component 8 is also provided with a third adjustment pad 83, wherein the third adjustment pad 83 is connected to the support frame 4 and the second adjustment pad 82 respectively, and is located below the second adjustment pad 82. With this configuration, the position of the cotter pin pressing head 51 in the vertical direction can be adjusted by increasing or decreasing the number of the third adjustment pad 83 or adjusting the size of the third adjustment pad 83. This can then be coordinated with the adjustment of the first adjustment pad 81 and the adjustment of the second adjustment pad 82 to further realize the flexible adjustment of the position of the cotter pin pressing head 51 in the space surrounding the cotter pin pressing point.

[0047] Optionally, the support frame 4 has multiple supports, each with a base 41 and a quick-change plate 6 having mounting holes 61. The base 41 is detachably mounted on the quick-change plate 6 via threaded connectors and mounting holes 61.

[0048] In this optional embodiment, to facilitate the simultaneous pressing of multiple cotter pin pressing points on the volute assembly 7 or cotter pin pressing points on different volute assemblies 7, such as... Figure 1 and Figure 2As shown, there are multiple support frames 4, and each support frame 4 has a base 41. The quick-change plate 6 has mounting holes 61. The base 41 is detachably mounted on the quick-change plate 6 through threaded connectors and mounting holes 61. Thus, by removing the threaded connectors, multiple support frames 4 can be flexibly installed on the quick-change plate 6. Furthermore, by adjusting the position of the support frames 4, multiple cotter pin press-fitting assemblies 5 on multiple support frames 4 can correspond to multiple cotter pin press-fitting points on the same volute assembly 7 or cotter pin press-fitting points on different volute assemblies 7, achieving synchronous press-fitting and effectively improving press-fitting efficiency.
