Description

Technical Field

[0001] This utility model belongs to the field of machine tool machining technology, and specifically relates to a high-efficiency vehicle tool for machining automotive structures. Background Technology

[0002] In the lathe machining of automotive structural components, traditional lathes generally suffer from the following problems: First, the connection structure between the fixed support arm and the base clamping plate lacks rigidity, making it prone to displacement or wobbling due to cutting forces, resulting in decreased machining accuracy. Second, the tool holder clamping relies on a single bolt for fixation, leading to low replacement efficiency and poor positioning accuracy, making it difficult to meet the continuous machining needs of workpieces with multiple specifications. Third, the tool working space is limited by the clamping plate structure, easily causing interference and narrowing its applicability. Fourth, the overall fastening system experiences uneven stress, resulting in significant vibration during high-load machining, affecting equipment stability and service life. Furthermore, traditional lathes lack a center of gravity adjustment mechanism, which, after long-term use, can easily lead to imbalance, accelerating component wear and further reducing machining quality.

[0003] To address the aforementioned technical pain points, this utility model proposes a novel vehicle fitting structure that integrates rigidity enhancement, efficient clamping, space optimization, and balance adjustment functions. The aim is to solve the comprehensive defects in the existing technology through multi-dimensional structural improvements, thereby enhancing the precision, efficiency, and equipment reliability of automotive structure processing. Summary of the Invention

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency machine tool for automotive structure processing, comprising a fixing plate fixed between a lower clamping plate and an upper clamping plate, both the lower and upper clamping plates being fixed on a lathe, a fixing arm fixedly provided at the end of the fixing plate, the fixing arm extending into the space between the lower and upper clamping plates, a clearance slot being provided through the middle of the fixing arm, and a mounting groove being provided on the side wall of the clearance slot away from the fixing plate, a tool holder being provided in the mounting groove, and a cutting tool being provided at the end of the tool holder away from the fixing arm.

[0005] As a further improvement of this utility model, the fixed support arm has a fixed threaded assembly extending through the top of the mounting groove, and the fixed threaded assembly is used to fix the tool bar.

[0006] As a further improvement of this utility model, the fixed thread assembly consists of two sets of first threaded holes and a first screw, wherein the first screw is rotated within the threaded hole by the thread.

[0007] As a further improvement of this utility model, the top of the upper clamping plate is provided with a plurality of second threaded holes, and a second screw is provided in each of the plurality of second threaded holes. The second screw is used to fix the fixing plate and the fixing arm.

[0008] As a further improvement of this utility model, a balance hole is also provided at the center of gravity of the fixed support arm.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The right-angle connection between the fixed plate and the fixed support arm enhances overall rigidity and stability, effectively preventing offset or shaking during processing and improving machining accuracy. The design of the fixed thread assembly and the positioning groove enables quick clamping and precise positioning of the tool holder, ensuring tool stability and improving changeover efficiency, making it suitable for continuous machining of workpieces of various specifications. The avoidance groove expands the tool's working space, avoids interference with the clamping plate structure, and improves machining flexibility and applicability. The multi-point distributed second threaded holes cooperate with the screw to form a uniformly stressed fastening system. Combined with the design of the balance hole and adjustable balance block, the center of gravity distribution is further optimized, vibration interference is reduced, and stability and service life are ensured under high-load machining conditions.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0014] See Figures 1 to 3As shown, a high-efficiency machine tool for machining automotive structures is characterized by: a fixing plate 3 fixed between a lower clamping plate 1 and an upper clamping plate 2, both of which are fixed on a lathe; a fixing arm 4 fixedly provided at the end of the fixing plate 3, the fixing arm 4 extending into the space between the lower clamping plate 1 and the upper clamping plate 2; a clearance slot 8 penetrating through the middle of the fixing arm 4; an installation groove 9 provided on the side wall of the clearance slot 8 away from the fixing plate 3; a tool holder 5 provided in the installation groove 9; and a cutting tool provided at the end of the tool holder 5 away from the fixing arm 4.

[0015] The fixing plate 3 is clamped and fixed by the lower clamping plate 1 and the upper clamping plate 2 on the lathe. After the fixing plate 3 is installed and fixed, the fixing arm 4 is connected to the fixing plate 3 by the two right-angled adjacent sides, thus achieving a stable connection of the fixing arm 4. The right-angle structure formed by the two adjacent sides makes the fixing arm 4 more stable during use, less prone to displacement or shaking, thereby improving the rigidity and precision of the overall structure.

[0016] Optionally, the fixed support arm 4 has a through-hole fixed thread assembly 6 at the top of the mounting groove 9, which is used to fix the tool holder 5. By setting the fixed thread assembly 6, the tool holder 5 can be firmly fixed in the mounting groove 9, ensuring the stability of the tool holder 5 during the machining process and avoiding the impact on machining accuracy or the scrapping of the workpiece due to the tool holder 5 loosening. Furthermore, the design of the clearance slot 8 allows the tool to avoid the connection between the lower clamping plate 1 and the upper clamping plate 2 when performing cutting operations, thereby improving the machining flexibility and applicability. In addition, the fixed support arm 4 and the fixed plate 3 are fixed with high strength by welding or bolting, ensuring that stable performance can still be maintained under high load machining conditions.

[0017] Optionally, the fixing thread assembly 6 consists of two sets of first threaded holes and a first screw. The first screw is rotated within the threaded holes via a thread. The two sets of first threaded holes are respectively located on the upper and lower sides of the mounting groove 9. The first screw can pass through the threaded holes and abut against the outer wall of the tool holder 5, achieving a stable fixation through bidirectional locking of the tool holder 5. This design effectively prevents the tool holder 5 from shifting due to vibration or cutting force during machining, thereby further ensuring machining accuracy and stability. In addition, this structure facilitates quick clamping and replacement of the tool holder 5, greatly improving the efficiency and applicability of the tool, especially suitable for continuous machining scenarios of workpieces of various specifications. Furthermore, a positioning groove is provided on the outer wall of the tool holder 5, which forms a precise fit with the end of the screw, allowing for quick alignment and locking of the tool holder 5 during installation, thereby improving clamping efficiency and accuracy. This design not only enhances the reliability of the tool holder 5 fixation but also reduces the accumulation of errors caused by repeated clamping, further ensuring the stability of machining quality.

[0018] Optionally, the top of the upper clamping plate 2 is provided with multiple second threaded holes, each containing a second screw. These second screws are used to fix the fixing plate 3 and the fixing arm 4. The cooperation of the multiple second threaded holes and the second screws provides multi-point fastening to the fixing plate 3 and the fixing arm 4, thereby enhancing the overall stability and uniform force distribution of the connection. Simultaneously, the close fit between the fixing plate 3 and the fixing arm 4, achieved through a right-angle structure formed by adjacent sides, ensures that the connection remains stable even under high cutting forces, preventing deformation or misalignment. This structure not only improves the overall rigidity of the fixture but also effectively reduces accuracy deviations caused by uneven force distribution, ensuring reliable stability even in high-intensity machining environments. Furthermore, this design offers good adaptability, allowing for flexible adjustment of the arm position according to different machining requirements, thereby expanding the equipment's application range and improving machining efficiency.

[0019] Optionally, a balance hole is provided at the center of gravity of the fixed support arm 4, and a balance block is installed in the balance hole via a stud threaded connection. By providing a balance hole at the center of gravity of the fixed support arm 4, the force distribution of the fixed support arm 4 during operation can be effectively adjusted, avoiding vibration or imbalance caused by center of gravity shift, thereby improving the stability and accuracy of the machining process. In addition, the balance hole can also reduce the overall weight of the fixed support arm 4 to a certain extent, reduce equipment energy consumption, and extend service life.

[0020] The balancing hole adopts an M12 threaded hole design. By adjusting the position of the balancing block in the inner balancing hole, the center of gravity of the fixed support arm 4 can be flexibly adjusted to ensure good stability under different working conditions. In practical applications, this balancing hole design can be arranged at multiple points according to processing requirements to achieve a more precise center of gravity adjustment function.

[0021] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
