Technical Field

[0001] This utility model relates to the field of front riser positioning technology, specifically to the positioning reference structure of a front riser boring machine for a vehicle frame. Background Technology

[0002] As a key component connecting the frame and the fork, the machining accuracy of the front seat tube's inner bore directly affects the vehicle's steering performance and safety. Currently, the industry commonly uses boring machines to machine the front seat tube's inner bore. The selection of the positioning reference and the structural design are the core factors affecting machining accuracy. With the development trend of lightweight and high-performance vehicles, higher requirements are placed on the machining accuracy of the front seat tube. Traditional positioning methods are no longer sufficient to meet the needs. In recent years, the popularization of CNC technology and automated equipment has further promoted the optimization of the positioning reference structure. The end of the front seat tube may have parts welded on it, so different tooling is needed to limit the front seat tube. Changing tooling each time is cumbersome, so an integrated tooling is needed.

[0003] In the existing technology, various toolings are required for the front riser limit during the production process. Each time the tooling is switched, the operator has to spend a lot of time disassembling, installing and debugging. This not only leads to the interruption of the production process and increases the equipment downtime, but also causes tooling damage and inaccurate positioning due to frequent operation, which seriously affects production efficiency and product quality stability. Therefore, we need a positioning reference structure for the frame front riser boring machine. Summary of the Invention

[0004] The purpose of this utility model is to provide a positioning reference structure for a front riser boring machine for a vehicle frame, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning reference structure for a front upright boring machine, comprising a base, a backing plate fixedly connected to the top of the base, a front upright provided on the top of the backing plate, a left and right clamping assembly provided on one side of the base, and an upper and lower clamping assembly provided on one side of the base. The left and right clamping assemblies include a first hydraulic cylinder, which is fixed inside the base. A push rod is fixedly connected to one end of the first hydraulic cylinder, and a connecting plate is fixedly connected to one end of the push rod. A mounting bracket is fixedly connected to one side of the connecting plate, and a side clamping plate is bolted to one side of the mounting bracket. A slide rail is slidably connected to the bottom of the mounting bracket.

[0006] Preferably, the base forms a telescopic structure with the first hydraulic cylinder and the push rod, and one end of the first hydraulic cylinder is fixed to one side of the base, and one end of the first hydraulic cylinder is fixed to one end of the push rod.

[0007] Preferably, the connecting plate forms a fixed structure with the side clamping plate through a mounting bracket, and the mounting bracket is disposed between the connecting plate and the side clamping plate.

[0008] Preferably, the base is connected to the mounting frame via a slide rail to form a sliding structure, and the slide rail is slidably connected to the bottom of the mounting frame.

[0009] Preferably, the upper and lower clamping assembly includes a second hydraulic cylinder, the output shaft of the second hydraulic cylinder is movably connected to an adjusting frame, one end of the adjusting frame is movably connected to a movable shaft, one end of the adjusting frame is fixedly connected to a fixed frame, and one side of the fixed frame is fixedly connected to a top clamping plate.

[0010] Preferably, the base is connected to the adjusting frame via a second hydraulic cylinder to form a movable structure, with the bottom of the second hydraulic cylinder fixed to the top of the base and the top of the second hydraulic cylinder movably connected to the top of the adjusting frame.

[0011] Preferably, the base is connected to the fixed frame via a movable shaft to form a movable structure, and the top of the movable shaft is hinged to the bottom of the fixed frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the positioning reference structure of the front riser boring machine for the chassis, (1) When facing the need for left and right positioning, a series of precise actions can be achieved by starting the first hydraulic cylinder. The first hydraulic cylinder drives the push rod, which in turn pushes the connecting plate and the mounting bracket to move. The mounting bracket slides stably by relying on the bottom slide rail, ensuring that the whole process is smooth and orderly. The side clamping plate on the mounting bracket can accurately position and install the front riser tube left and right. This design is not only easy to operate and can quickly complete the positioning and installation, improving work efficiency, but also ensures the accuracy and stability of positioning through the slide rail, effectively improving product quality. (2) By starting the second oil cylinder, the adjusting frame is driven to rotate and move around the movable shaft, thereby driving the top clamping plate to accurately clamp and position the front riser, which greatly improves the positioning stability and provides a reliable guarantee for subsequent installation processes. Its advantage lies in its strong versatility, which can flexibly adapt to the positioning and installation requirements of front risers of different specifications, effectively reducing equipment replacement costs and operational complexity. At the same time, even if there are welded parts at the front end of the front riser, the top clamping plate can still be firmly fixed, fully meeting the fixing requirements of various front risers, and improving production efficiency and product quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model embodiment provides a positioning reference structure for a boring machine of the front riser tube of a vehicle frame, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the system includes a base 1, a backing plate 2 fixedly connected to the top of the base 1, a front upright tube 3 mounted on the top of the backing plate 2, a left and right clamping assembly 4 mounted on one side of the base 1, and a top and bottom clamping assembly 5 mounted on the other side of the base 1. The left and right clamping assembly 4 includes a first hydraulic cylinder 401, which is fixed inside the base 1. A push rod 402 is fixedly connected to one end of the first hydraulic cylinder 401, and a connecting plate 403 is fixedly connected to one end of the push rod 402. A mounting bracket 405 is fixedly connected to one side of the connecting plate 403, and a side clamping plate 404 is bolted to one side of the mounting bracket 405. The bottom of 405 is slidably connected to a slide rail 406. When the front riser 3 is placed on the back plate 2 at the top of the base 1 and left and right positioning is required, the first hydraulic cylinder 401 can be activated, which can drive the push rod 402 to move. The push rod 402 can drive the connecting plate 403 to move, which can drive the mounting bracket 405 to move. The mounting bracket 405 can slide stably on the slide rail 406 at the bottom, and the side clamping plate 404 on the mounting bracket 405 can position and install the front riser 3 left and right.

[0017] Furthermore, such as Figure 4As shown, the base 1 forms a telescopic structure with the first hydraulic cylinder 401 and the push rod 402. One end of the first hydraulic cylinder 401 is fixed to one side of the base 1, and one end of the first hydraulic cylinder 401 is fixed to one end of the push rod 402. With the first hydraulic cylinder 401, the first hydraulic cylinder 401 can push the push rod 402 to move by relying on the base 1, and the push rod 402 can drive the connecting plate 403 to adjust its position.

[0018] Furthermore, such as Figure 4 As shown, the connecting plate 403 forms a fixed structure with the side clamping plate 404 through the mounting bracket 405, and the mounting bracket 405 is disposed between the connecting plate 403 and the side clamping plate 404. Through the connection plate 403, the connecting plate 403 can support the side clamping plate 404 by relying on the mounting bracket 405, which can improve the fixing effect of the side clamping plate 404.

[0019] Furthermore, such as Figure 3 and Figure 4 As shown, the base 1 forms a sliding structure with the mounting bracket 405 via the slide rail 406, and the slide rail 406 is slidably connected to the bottom of the mounting bracket 405, which strengthens the connection between the base 1 and the mounting bracket 405, allowing the mounting bracket 405 to slide against the outer wall of the slide rail 406, thus improving the adjustment stability.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the upper and lower clamping assembly 5 includes a second hydraulic cylinder 501. The output shaft of the second hydraulic cylinder 501 is movably connected to an adjusting frame 502. One end of the adjusting frame 502 is movably connected to a movable shaft 503. One end of the adjusting frame 502 is fixedly connected to a fixed frame 504. A top clamping plate 505 is fixedly connected to one side of the fixed frame 504. By activating the second hydraulic cylinder 501, the second hydraulic cylinder 501 can drive the adjusting frame 502 to rotate, allowing the adjusting frame 502 to move by the movable shaft 503. This allows the adjusting frame 502 to drive the top clamping plate 505 on the fixed frame 504 to clamp and position the front riser 3, thereby improving the positioning stability of the front riser 3. This facilitates the positioning and installation of different front risers 3. Furthermore, when there are welded parts at the front end of the front riser 3, they can be fixed by the top clamping plate 505, which facilitates the positioning structure's need to fix various different front risers 3.

[0021] Furthermore, such as Figure 2 , Figure 3 and Figure 5As shown, the base 1 forms a movable structure with the adjusting frame 502 through the second oil cylinder 501, and the bottom of the second oil cylinder 501 is fixed to the top of the base 1, and the top of the second oil cylinder 501 is movably connected to the top of the adjusting frame 502. By setting the second oil cylinder 501, the second oil cylinder 501 can adjust the angle of the adjusting frame 502 with the support of the base 1.

[0022] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, the base 1 forms a movable structure with the fixed frame 504 through the movable shaft 503, and the top of the movable shaft 503 is hinged to the bottom of the fixed frame 504, which strengthens the connection between the movable shaft 503 and the base 1. This allows the base 1 to support the fixed frame 504 by relying on the movable shaft 503, and makes it easy for the fixed frame 504 to move and adjust along the movable shaft 503.

[0023] Working principle: In use, the front riser 3 is placed on the backing plate 2 at the top of the base 1. When left and right positioning is required, the first hydraulic cylinder 401 is activated, which moves the push rod 402. The push rod 402 moves the connecting plate 403, which in turn moves the mounting bracket 405. The mounting bracket 405 can then slide stably on the bottom slide rail 406, allowing the side clamping plate 404 on the mounting bracket 405 to position and install the front riser 3 left and right. In another mode, for the front riser 3 with welded ends... When installing parts, the upper and lower positioning mode can be used. By activating the second hydraulic cylinder 501, the second hydraulic cylinder 501 can drive the adjusting frame 502 to rotate, allowing the adjusting frame 502 to move along the movable shaft 503. This allows the adjusting frame 502 to drive the top clamping plate 505 on the fixed frame 504 to clamp and position the front riser 3, thereby improving the positioning stability of the front riser 3. This facilitates the positioning and installation of different front risers 3. Furthermore, when there are welded parts at the front end of the front riser 3, they can be fixed by the top clamping plate 505, which facilitates the positioning structure to fix various different front risers 3.
