Description

Technical Field

[0001] This utility model relates to the field of tooling assembly technology, specifically to a tooling assembly for a vehicle frame side beam assembly. Background Technology

[0002] In the manufacturing process of vehicle frames for commercial vehicles, construction machinery, and other fields, the frame side beams, as core load-bearing components, directly determine the structural strength and service life of the entire frame through their machining accuracy and assembly stability. Frame side beams are typically long, strip-shaped metal components. Before subsequent processing steps such as welding, drilling, and painting, they must be precisely positioned and fixed using specialized tooling assemblies to prevent displacement or wobbling during processing and to ensure that the machining dimensions meet design requirements.

[0003] Currently, the existing chassis side beam assembly tooling in the industry generally adopts a design approach of positioning tooling at both ends for positioning and fixing. This type of tooling typically only sets simple clamping or supporting structures at the left and right ends of the side beam, attempting to fix the side beam through limitation at both ends. However, in actual production applications, this positioning method has certain limitations, the core problem being that the positioning tooling is not stable enough. On the one hand, the side beams of the frame are relatively long, and relying solely on positioning at both ends cannot effectively constrain the middle area of ​​the side beams. During the processing, the middle of the side beams is prone to bending and displacement due to external forces, such as welding stress and the force of the processing tools, resulting in the overall straightness deviation of the side beams exceeding the standard. On the other hand, the clamping points of the positioning fixtures at both ends are relatively simple and cannot adapt to the differences in the shape of different specifications of the side beams. When there is a slight curvature or protrusion on the surface of the side beam, the fit between the fixture and the side beam is insufficient, which can easily cause gaps. This can lead to slight shaking of the side beam during the processing, ultimately affecting key processing indicators such as hole position accuracy and weld joint quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a chassis side beam assembly tooling assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A frame side beam assembly tooling assembly includes: a tooling bracket, bearing seats and a reducer respectively disposed on the top of the left and right sides of the tooling bracket, a wheel disk disposed on the rear side of the reducer, a rotating chassis movably disposed between the bearing seats and the reducer, the upper and lower sides of the rotating chassis being symmetrically arranged, multiple sets of clamping components disposed on the front top of the rotating chassis, and clamping components disposed on the left and right sides of the rear top of the rotating chassis, a foolproof tooling component disposed on the side of the clamping component near the bearing seat, the clamping components being used to clamp the side beam against the upper and lower top of the rotating chassis, the wheel disk being used to manually rotate to drive the rotating chassis to rotate, the clamping components being used to contact the side of the side beam to clamp and limit the side beam, and the foolproof tooling component being used to fix the foolproof shaft on the side beam.

[0006] Preferably, the clamping assembly includes a short support base and a long support base, which are arranged side by side. A wrench fixing component is fixedly installed on the top of the short support base, and a rotating fixing component is installed on the top of the long support base. A clamping bolt is installed on the right side of the rotating fixing component. The wrench fixing component is used to rotate the wrench to control the extension and retraction of the clamping rod and clamp the side of the side beam. The rotating fixing component is used to rotate the wrench to drive the clamping bolt to rotate, and the clamping bolt presses against the top surface of the side beam.

[0007] Preferably, the clamping assembly includes: a support column and a fixed seat. The support column has a rotating shaft at its top, and a limit block is movably connected to the rotating shaft. The fixed seat has a bolt clamping handle at its top. A support seat is provided between the support column and the fixed seat. The limit block is used to rotate around the rotating shaft to rotate the limit block to the top surface of the side beam for limiting. The bolt clamping handle is used to rotate the handle to make the bolt clamping rod contact the side of the side beam to clamp the side beam. The support seat is used to contact the bottom surface of the side beam for limiting.

[0008] Preferably, the foolproof tooling assembly includes: a second support column, a bolt handle fitted on the top pivot of the second support column, an arc-shaped pressure plate at the bottom of the bolt handle, a shaft support seat below the arc-shaped pressure plate, the bottom of the shaft support seat being fixedly connected to the rotating chassis by bolts, the shaft support seat being used to place the foolproof shaft on top, and the bolt handle being used to rotate the handle to press the arc-shaped pressure plate downwards to fix the foolproof shaft on the shaft support seat.

[0009] Compared with the prior art, this utility model provides a chassis side beam assembly tooling assembly, which has the following beneficial effects: The clamping assembly applies pressure from the side and top surfaces of the side beam through a combination design of short and long support seats. The wrench fixing component controls the extension and retraction of the clamping rod to clamp the side surface of the side beam, and the rotating fixing component drives the clamping bolt to press the top surface of the side beam, thus achieving dual fixation of the side beam in both the lateral and longitudinal directions. The clamping assembly further supplements the limiting position from the bottom and sides of the side beam. The support seat contacts the bottom of the side beam to provide bottom support. The bolt clamping handle drives the bolt clamping rod to fit against the side of the side beam. At the same time, the limiting block rotates around the pivot to the top of the side beam to form a top constraint. The three work together to form a three-dimensional fixed structure.

[0010] This multi-directional, multi-angle clamping and positioning method solves the problem of unstable positioning at both ends of existing tooling, effectively avoids bending, offset and shaking during the processing of the side beam, ensures that key indicators such as the straightness and hole accuracy of the side beam meet the design requirements, and improves the processing quality.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0014] Reference Figures 1-6As shown, a frame side beam assembly tooling assembly of this embodiment includes a tooling bracket 1. The tooling bracket 1 serves as the basic support component of the entire tooling assembly, providing a stable mounting carrier for other components and ensuring that the overall structure of the tooling does not shift during use.

[0015] The top of the left and right sides of the tooling bracket 1 are fixedly connected to the bearing housing 201 and the reducer 202 respectively by bolts. This fixing method can ensure the stability of the position of the bearing housing 201 and the reducer 202 and prevent loosening after long-term use. The rear side of the reducer 202 is welded to the wheel 203. The welding connection ensures the transmission stability between the wheel 203 and the reducer 202. The presence of the wheel 203 provides a manual operating part for adjusting the angle of the rotating chassis 3.

[0016] The bearing housing 201 and the reducer 202 are movably connected to the rotating chassis 3. This movable connection ensures that when the wheel 203 is rotated manually, the reducer 202 can drive the rotating chassis 3 to rotate smoothly, making it convenient for operators to adjust the machining angle of the side beam 7. The upper and lower sides of the rotating chassis 3 are symmetrically arranged. This symmetrical structure allows for simultaneous positioning and machining of the side beam 7 from both sides, improving the efficiency of tooling use.

[0017] The top front side of the rotating chassis 3 is detachably connected to multiple sets of clamping components 4 via bolts. This detachable connection allows for flexible adjustment of the number of clamping components 4 according to the specifications of the side beam 7, ensuring the clamping effect on the side beam 7. The left and right sides of the rear top of the rotating chassis 3 are welded and fixed to the clamping components 5. This welding and fixing ensures that the clamping components 5 will not shift when clamping the side beam 7, improving positioning stability.

[0018] The side of the clamping assembly 5 closest to the bearing housing 201 is fixedly connected to the foolproof tooling assembly 6 by bolts. This fixed connection method ensures that the foolproof tooling assembly 6 can accurately correspond to the installation position of the foolproof shaft on the side beam 7, and avoids the foolproof shaft from being fixed off-center.

[0019] The clamping assembly 4 applies pressure from the side and top surfaces of the side beam 7 through the combination of the short support base 401 and the long support base 402: the wrench fixing part 403 at the top of the short support base 401 controls the extension and retraction of the clamping rod to clamp the side surface of the side beam 7, and the rotating fixing part 404 at the top of the long support base 402 drives the clamping bolt 405 to press the top surface of the side beam 7, thereby achieving dual fixation of the side beam 7 in both the lateral and longitudinal directions; in the clamping assembly 5, the support base 505 contacts the bottom surface of the side beam 7 to provide bottom support, the bolt clamping handle 504 drives the bolt clamping rod to fit against the side surface of the side beam 7, and the limiting block 502 rotates around the pivot to the top surface of the side beam 7 to form a top constraint. The three components work together to form a three-dimensional fixing structure, effectively preventing the side beam 7 from shifting during processing.

[0020] In some examples, the bottom of the clamping bolt 405 of the clamping assembly 4 is provided with an elastic rubber pad, which is fixedly connected to the clamping bolt 405 by adhesive. The elastic rubber pad can buffer the bolt 405 when it presses against the top surface of the side beam 7, preventing the bolt from directly contacting the surface of the side beam 7 and causing indentations or damage. At the same time, it increases the friction between the clamping bolt 405 and the side beam 7, improving the clamping stability.

[0021] In some examples, the inner side of the arc-shaped pressure plate 604 of the foolproof tooling assembly 6 is provided with a silicone pad, which is fixed to the inner side of the arc-shaped pressure plate 604 by an embedded installation. The silicone pad has good flexibility and can closely fit the surface of the foolproof shaft when the arc-shaped pressure plate 604 presses it, which not only ensures that the foolproof shaft is firmly fixed, but also avoids the pressure plate from scratching or damaging the surface of the foolproof shaft, thus protecting the appearance and accuracy of the foolproof shaft.

[0022] The working principle of this utility model is as follows: When using this frame side beam assembly tooling, select a flat and stable installation area according to the specifications and dimensions of the side beam 7 to be processed. Place the tooling bracket 1 stably, utilizing the rigid frame structure of the tooling bracket 1 to ensure its overall stability and avoid affecting the positioning accuracy due to foundation shaking during subsequent processing. Next, check the connection status of each component: confirm whether the fixed connection between the bearing housing 201 and the reducer 202 and the top of the tooling bracket 1 via bolts is secure, whether the welding between the wheel 203 and the rear side of the reducer 202 is reliable, and whether the movable connection between the rotating chassis 3 and the bearing housing 201 and the reducer 202 is smooth, ensuring that there is no loosening or jamming of any parts, laying the foundation for the subsequent positioning and processing of the side beam.

[0023] The positioning and fixing process of the side beam 7 then begins. First, the side beam 7 to be processed is placed at the preset position on the top of the rotating chassis 3, so that the bottom surface of the side beam 7 is in full contact with the support seat 505 in the clamping assembly 5. The support seat 505, as the bottom support structure, can initially limit the vertical position of the side beam 7 and prevent the side beam 7 from shifting vertically in subsequent operations. Next, the clamping assembly 5 is operated to complete the side and top surface constraints of the side beam 7: First, rotate the limiting block 502 on the top rotating shaft of the support column 501 so that it rotates around the rotating shaft to the top surface of the side beam 7. The top limit is formed by the contact between the limiting block 502 and the top surface of the side beam 7. Then, rotate the bolt clamping handle 504 on the top of the fixing seat 503 to drive the bolt clamping rod to move to the side of the side beam 7 until the bolt clamping rod is tightly attached to the side of the side beam 7. The side beam 7 is initially clamped and fixed by the lateral pressure. At this time, the support seat 505, the limiting block 502 and the bolt clamping rod cooperate to form a preliminary three-dimensional constraint on the side beam 7 from the bottom, top and side directions.

[0024] After completing the operation of the clamping assembly 5, the pressing assembly 4 is activated to further strengthen the fixing effect of the side beam 7. For the multiple pressing assemblies 4 on the front top of the rotating chassis 3, first operate the wrench fixing part 403 on the top of the short support 401: control the extension and retraction of the pressing rod by rotating the wrench, so that the pressing rod extends to the side of the side beam 7 and tightly abuts, applying pressure to the side of the side beam 7 from the lateral direction, supplementing the lateral constraint of the clamping assembly 5, and preventing the side beam 7 from shifting laterally; then operate the rotating fixing part 404 on the top of the long support 402: similarly, drive the right-side pressing bolt 405 to rotate by rotating the wrench, so that the pressing bolt 405 moves vertically downward until the bottom of the pressing bolt 405 is in close contact with the top surface of the side beam 7 and applies pressure, forming a secondary pressing on the top surface of the side beam 7 from the longitudinal direction. At this time, the clamping component 4 and the top clamping component work together to form a comprehensive and stable clamping and positioning of the side beam 7 from multiple dimensions, including the horizontal, vertical and longitudinal directions. This completely solves the problem of unstable positioning of existing tooling that relies only on the two ends, and avoids bending and displacement of the side beam 7 during subsequent processing.

[0025] If the anti-misalignment shaft needs to be installed during the processing of the side beam 7, the anti-misalignment tooling assembly 6 can be operated simultaneously to fix the anti-misalignment shaft. First, place the anti-misalignment shaft in the groove at the top of the shaft support 603. The shaft support 603 is fixedly connected to the rotating base 3 by bolts. Its position corresponds precisely to the mounting hole of the anti-misalignment shaft on the side beam 7, which can ensure the initial positioning accuracy of the anti-misalignment shaft. Then, rotate the bolt handle 602 on the top rotating shaft of the support column 2 601 to drive the arc-shaped pressure plate 604 at the bottom to move downward until the arc-shaped pressure plate 604 is tightly attached to the surface of the anti-misalignment shaft. The squeezing force of the arc-shaped pressure plate 604 firmly fixes the anti-misalignment shaft on the shaft support 603. The anti-misalignment shaft is then welded and fixed to the side beam 7 by spot welding.

[0026] During the machining of the side beam 7, if the machining angle needs to be adjusted, it can be achieved by manually rotating the wheel 203. The wheel 203 is fixedly connected to the rear side of the reducer 202. When the wheel 203 is rotated, the power is transmitted to the rotating chassis 3 through the reducer 202. Since the rotating chassis 3 is movably connected to the bearing seat 201 and the reducer 202, the rotating chassis 3 can rotate smoothly around the horizontal axis under the drive of the wheel 203, thereby synchronously adjusting the angle of the fixed side beam 7. The operator can precisely adjust the angle of the side beam 7 by controlling the rotation amplitude of the wheel 203 according to the machining requirements, without disassembling the side beam 7 for repositioning, which greatly improves the machining flexibility and efficiency, and is especially suitable for scenarios where the side beam 7 is machined on multiple sides.

[0027] After the side beam 7 is processed, the constraints of each component must be released in the reverse order of fixing, and the processed side beam 7 must be removed. First, rotate the bolt handle 602 of the anti-foolproof tooling component 6 in the reverse direction to lift the arc-shaped pressure plate 604 upward and disengage it from the anti-foolproof shaft; then rotate the wrench fixing part 403 and the rotating fixing part 404 of the clamping component 4 in the reverse direction to retract the clamping rod and lift the clamping bolt 405 upward, releasing the clamping on the side and top surface of the side beam 7; then rotate the bolt clamping handle 504 and the limiting block 502 of the top clamping component 5 in the reverse direction to retract the bolt clamping rod and rotate the limiting block 502 away from the top surface of the side beam 7, and finally remove the side beam 7 from the rotating chassis 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
