Description
Technical Field
[0001] This utility model relates to the field of automotive clay modeling technology, and in particular to an adjustable split skeleton for automotive clay models. Background Technology
[0002] In the field of automotive clay model making, the skeleton, as the core supporting structure for clay shaping, directly affects the consistency between the model and the real vehicle in terms of positioning accuracy. With the continuous increase in the size of heavy-duty vehicle exteriors, split skeletons are widely used due to their ease of processing and transportation. However, this type of structure faces many difficulties during assembly: the welding deviations of the upper and lower skeletons, combined with processing errors, result in a large amount of manpower required for position calibration during assembly, and reliance on equipment such as cranes for adjustment, which poses safety risks.
[0003] In the prior art, Chinese patent application publication number CN109064869A discloses an adjustable wheel axle type clay model skeleton, including a main skeleton, which is welded together from multiple support rods. An adjustable wheel axle mounting mechanism is provided at the mounting wheel axle position of the main skeleton. The adjustable wheel axle mounting mechanism is used to fix the wheel axle to the main skeleton. The adjustable wheel axle mounting mechanism includes: a wheel axle main mounting plate, a vertical moving connecting plate, a horizontal moving connecting plate, and a measuring reference block. The vertical moving connecting plate is slidably connected to the wheel axle main mounting plate vertically, and the horizontal moving connecting plate is slidably connected to the vertical moving connecting plate horizontally.
[0004] Although the above-mentioned frame can achieve position calibration through the vertical and horizontal sliding structure of the wheel and axle mounting mechanism, it still has the following shortcomings in actual use: First, it can only be used for local adjustment of the overall frame and cannot solve the overall positioning problem of the upper and lower parts of the split frame; second, it relies on the measurement reference block for indirect positioning, which is difficult to operate and the accuracy is hard to guarantee; third, the structural design does not consider disassembly, and the cost of reuse is high. Utility Model Content

The unit has an adjustment groove A that communicates with the mounting groove; the connecting post is disposed inside the adjustment groove A, and the end of the connecting post away from the upper frame can extend into the mounting groove through the adjustment groove A; the fixed seat is provided with a transverse adjustment bolt that can extend into the mounting groove on the side away from the lower frame, and the transverse adjustment bolt can abut against the end of the connecting post after extending into the mounting groove; the fixed seat is provided with longitudinal adjustment bolts that can extend into the mounting groove on both sides, and the two longitudinal adjustment bolts can abut against the side of the connecting post after extending into the mounting groove.
[0007] The connecting post at the bottom of the upper frame is inserted into the adjusting groove A of the fixing seat and extends into the mounting groove. By rotating the lateral adjusting bolt against the end of the connecting post, the left-right relative position of the upper and lower frames can be adjusted; by rotating the longitudinal adjusting bolts on both sides against the sides of the connecting post, the front-back relative position can be adjusted. The two symmetrically arranged positioning and adjusting mechanisms work synchronously to form a stable bidirectional adjustment structure.
[0008] This skeleton achieves precise bidirectional adjustment of the upper and lower parts of the split skeleton in both front-to-back and left-to-right directions through a symmetrical positioning and adjustment mechanism. This solves the assembly deviation problem caused by the large size of heavy-duty automobile clay models, avoids the time-consuming and labor-intensive traditional manual calibration, and significantly improves assembly efficiency. At the same time, the mechanical adjustment effectively improves positional accuracy and reduces assembly errors.
[0009] A further improvement of this utility model is that the fixed base has a connecting through hole A for installing a transverse adjusting bolt on the side away from the lower frame, and connecting through holes B for installing a longitudinal adjusting bolt on both sides of the fixed base, and a fixing nut located inside the mounting groove is screwed onto both the transverse adjusting bolt and the longitudinal adjusting bolt.
[0010] A further improvement of this utility model is that a reinforcing plate is provided inside the mounting groove, and an adjusting groove B corresponding to the adjusting groove A is opened on the top of the reinforcing plate, and the connecting post is disposed inside the adjusting groove A and the adjusting groove B; connecting through holes C for installing longitudinal adjusting bolts are respectively opened on both sides of the reinforcing plate, and the longitudinal adjusting bolts can extend into the adjusting groove B through the connecting through holes C, so that the longitudinal adjusting bolts can abut against the side of the connecting post after extending into the adjusting groove B.
[0011] A further improvement of this utility model is that guide rounded corners are provided on both sides of the opening of the adjustment groove A, and guide inclined surfaces are provided on both sides of the opening of the adjustment groove B.
[0012] A further improvement of this utility model is that the bottom two sides of the reinforcing plate are respectively provided with connecting through holes D, and the bottom of the fixing seat near the lower frame is provided with a connecting through hole E corresponding to the connecting through hole D; the fixing seat and the reinforcing plate are connected through the connecting through hole E, the fixing nut, the connecting through hole D and the connecting bolt A.
[0013] A further improvement of this utility model is that a fixing plate is provided on the side of the fixing seat near the lower frame, and a connecting through hole F corresponding to the connecting through hole E is opened at the bottom of the fixing plate. The fixing seat is connected to the fixing plate through a fixing nut, a connecting bolt A and the connecting through hole F, and the two ends of the fixing plate are connected to the lower frame through a fixing nut and a connecting bolt B, respectively.
[0014] A further improvement of this utility model is that the connecting through hole B, connecting through hole E and connecting through hole F are all waist holes.
[0015] A further improvement of this utility model is that the fixing plate has a T-shaped structure.
[0016] A further improvement of this utility model is that there are two positioning adjustment mechanisms, and the two positioning adjustment mechanisms are arranged symmetrically.
[0017] A further improvement of this utility model is that a support plate is provided at the bottom of the lower frame.

By employing horizontal and vertical adjusting bolts against connecting columns, the relative positions of the upper and lower frames can be precisely adjusted, resolving assembly deviations caused by machining errors in split frames for heavy-duty vehicles. This ensures that the model's wheel positions match those of the real vehicle, improving overall manufacturing accuracy. Simultaneously, the composite support structure of the reinforcing plate and fixed base enhances the uniformity of stress distribution, enabling it to withstand large loads without deformation, further guaranteeing the model's accuracy and stability.
[0020] 2. The structural design of this frame facilitates installation, disassembly, and reuse, significantly improving work efficiency. The guide rounded corners and beveled surfaces ensure smoother insertion of connecting columns, shortening installation time; the waist-hole structure accommodates machining errors, reducing rework; and the bolted connection method allows for quick disassembly and high reusability. Furthermore, the symmetrically arranged positioning and adjustment mechanisms and T-shaped fixing plates create a stable installation structure, reducing safety risks during the assembly of large frames and making on-site assembly more convenient and efficient.
[0021] 3. This frame utilizes mechanical adjustment instead of traditional manual calibration, effectively improving assembly efficiency and saving labor costs. The detachable structure reduces material waste and lowers material costs. The support plates enhance the compressive strength of the lower frame, extending its service life and reducing maintenance costs.

Detailed Implementation
[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0032] Now refer to Figures 1-7The following is a description of a specific embodiment: The adjustable split frame for an automotive clay model according to this utility model includes an upper frame 1 and a lower frame 2. A positioning adjustment mechanism is provided between the upper frame 1 and the lower frame 2, and two such positioning adjustment mechanisms are provided, symmetrically arranged. The positioning adjustment mechanism allows the upper frame 1 and the lower frame 2 to be connected as a whole, and the relative position between the upper frame 1 and the lower frame 2 to be adjusted. The positioning adjustment mechanism includes a connecting column 3 and a fixing seat 4. The connecting column 3 is fixed to the inner bottom side of the upper frame 1, and the fixing seat 4 is fixed to the inner top side of the lower frame 2. The top of the fixing seat 4 has an installation groove 401, and the fixing seat 4 is close to the lower frame 2. The top of one side of the frame 2 is provided with an adjustment groove A402 that communicates with the mounting groove 401; the connecting post 3 is disposed inside the adjustment groove A402, and the end of the connecting post 3 away from the upper frame 1 can extend into the mounting groove 401 through the adjustment groove A402; the side of the fixing seat 4 away from the lower frame 2 is provided with a transverse adjustment bolt 6 that can extend into the mounting groove 401, and the transverse adjustment bolt 6 can abut against the end of the connecting post 3 after extending into the mounting groove 401; the two sides of the fixing seat 4 are respectively provided with longitudinal adjustment bolts 7 that can extend into the mounting groove 401, and the two longitudinal adjustment bolts 7 can abut against the side of the connecting post 3 after extending into the mounting groove 401.
[0033] The connecting post 3 at the bottom of the upper frame 1 is inserted into the adjusting groove A402 of the fixing seat 4 and extends into the mounting groove 401. By rotating the lateral adjusting bolt 6 against the end of the connecting post 3, the left-right relative position of the upper frame 2 and the lower frame 2 can be adjusted; by rotating the longitudinal adjusting bolts 7 on both sides against the sides of the connecting post, the front-back relative position can be adjusted. The two symmetrically arranged positioning and adjusting mechanisms work synchronously to form a stable bidirectional adjustment structure.
[0034] This skeleton achieves precise bidirectional adjustment of the upper and lower parts of the split skeleton in both front-to-back and left-to-right directions through a symmetrical positioning and adjustment mechanism. This solves the assembly deviation problem caused by the large size of heavy-duty automobile clay models, avoids the time-consuming and labor-intensive traditional manual calibration, and significantly improves assembly efficiency. At the same time, the mechanical adjustment effectively improves positional accuracy and reduces assembly errors.
[0035] Specifically, refer to Figures 3-6 The fixed base 4 has a connecting through hole A403 for installing the transverse adjusting bolt 6 on the side away from the lower frame 2. The fixed base 4 has connecting through holes B404 for installing the longitudinal adjusting bolt 7 on both sides. The transverse adjusting bolt 6 and the longitudinal adjusting bolt 7 are both screwed with a fixing nut 8 located inside the mounting groove 401.
[0036] The lateral adjusting bolt 6 passes through the connecting through hole A403 and enters the mounting groove 401. The longitudinal adjusting bolt 7 passes through the connecting through hole B404 and enters the groove. After the bolt end abuts against the connecting column, it is locked inside the groove by the fixing nut 8 to prevent the bolt from loosening.
[0037] The frame features a locking structure thanks to the design of the fixing nut 8. This ensures that the adjusted position remains stable even during model handling or long-term use due to vibration, preventing model deformation caused by loose bolts, improving structural reliability, and effectively reducing subsequent maintenance costs.
[0038] Specifically, refer to Figures 3-7 The mounting groove 401 is provided with a reinforcing plate 9. The top of the reinforcing plate 9 is provided with an adjusting groove B901 corresponding to the adjusting groove A402. The connecting post 3 is provided inside the adjusting groove A402 and the adjusting groove B901. The reinforcing plate 9 is provided with connecting through holes C902 on both sides for installing longitudinal adjusting bolts 7. The longitudinal adjusting bolts 7 can extend into the adjusting groove B901 through the connecting through holes C902, so that the longitudinal adjusting bolts 7 can abut against the side of the connecting post 3 after extending into the adjusting groove B901.
[0039] The reinforcing plate 9 is installed in the mounting groove 401, with its adjusting groove B901 aligned with the adjusting groove A402. The connecting post 3 passes through both grooves simultaneously. The longitudinal adjusting bolt 7 passes through the connecting through hole C902 of the reinforcing plate and abuts against the side of the connecting post. The reinforcing plate provides a support base for the adjusting bolt.
[0040] The addition of reinforcing plate 9 upgrades the single-structure support of fixed base 4 to a composite support, making the structure more evenly stressed during adjustment and able to withstand greater adjustment pressure without deformation. At the same time, it enhances the anti-overturning ability of the entire positioning mechanism, making it suitable for heavy load scenarios of heavy vehicle models.
[0041] In one embodiment, guide fillets 406 are provided on both sides of the opening of the adjustment groove A402, and guide slopes 904 are provided on both sides of the opening of the adjustment groove B901.
[0042] The guide radius 406 of the adjusting groove A402 and the guide slope 904 of the adjusting groove B901 form a guide track when the connecting post 3 is inserted, reducing the insertion resistance and allowing the connecting post to slide smoothly into the groove.
[0043] This frame significantly shortens the installation time of the connecting column 3 through the aforementioned guide structure, avoids wear and tear on components caused by hard collisions during manual alignment, reduces installation errors, and ensures the coaxiality of the initial position of the connecting column 3 with the axis of the adjusting bolt, thereby guaranteeing the accuracy of subsequent adjustments.
[0044] Specifically, refer to Figures 3-7 The bottom sides of the reinforcing plate 9 are respectively provided with connecting through holes D903, and the bottom of the fixing seat 4 near the lower frame 2 is provided with a connecting through hole E405 corresponding to the connecting through hole D903; the fixing seat 4 and the reinforcing plate 9 are connected through the connecting through hole E405, the fixing nut 8, the connecting through hole D903 and the connecting bolt A10.
[0045] The reinforcing plate 9 is connected to the fixing base 4 via the connecting through holes D903 and E405 using connecting bolts A10 and fixing nuts 8, forming a detachable rigid whole to ensure that the reinforcing plate will not shift during adjustment.
[0046] The frame allows the reinforcing plate 9 to be quickly disassembled after the model is used, thanks to the detachable connection method described above. This results in a high reuse rate, saving material costs and facilitating the replacement of worn parts, thus shortening maintenance time.
[0047] Specifically, refer to Figures 3-7 The fixing base 4 is provided with a T-shaped fixing plate 11 on the side near the lower frame 2. The bottom of the fixing plate 11 is provided with a connecting through hole F1101 corresponding to the connecting through hole E405. The fixing base 4 is connected to the fixing plate 11 through a fixing nut 8, a connecting bolt A10 and the connecting through hole F1101. The two ends of the fixing plate 11 are connected to the lower frame 2 through a fixing nut 8 and a connecting bolt B12, respectively.
[0048] The T-shaped fixing plate 11 is connected to the fixing base 4 through the connecting through hole F1101, and its two ends are fixed to the lower frame 2 with connecting bolts B12, forming a stable installation structure of T-shaped support + bolt connection.
[0049] The frame distributes the load of the positioning and adjustment mechanism evenly to the square tube of the lower frame 2 through the T-shaped fixing plate 11, avoiding local stress concentration and allowing it to withstand greater vertical loads. At the same time, the bolt connection method makes the installation accuracy of the entire device controllable and the installation error low, which can meet the high precision requirements of the clay model.
[0050] In one embodiment, reference Figure 4 and Figure 6 The connecting through holes B404, E405 and F1101 are all oblong holes.
[0051] The design of the waist hole connecting through holes B, E and F allows the bolt to slide slightly within the hole. When adjusting the bolt to change the position of the connecting post, the waist hole provides room for component displacement, avoiding structural jamming caused by the rigid restriction of the bolt.
[0052] This frame effectively reduces displacement resistance during adjustment through its waist hole structure, making adjustment smoother. It also accommodates machining errors during frame welding, allowing installation to be completed without additional repairs. This increases the tolerance for errors in on-site assembly and significantly reduces the number of rework operations.
[0053] In one embodiment, reference Figure 1 and Figure 2 The bottom of the lower frame 2 is provided with a support plate 5.
[0054] The support plate 5 is fixed to the bottom of the lower frame 2, increasing the contact area between the lower frame 2 and the ground, and providing additional support for the entire split frame.
[0055] This frame, through the support plate 5, can improve the compressive strength of the lower frame 2, effectively preventing the deformation of the lower frame 2 caused by the weight of the heavy vehicle model, ensuring the model remains stable during long-term use, especially suitable for large-sized clay models, and can reduce the overall verticality error of the frame.
[0056] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
