Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and more specifically, it relates to an integrated tool magazine support for a double-head machine tool. Background Technology

[0002] The tool magazine support of a double-headed machine tool is a key transitional component connecting the tool magazine and the machine tool column. Its core function is to ensure the stable operation of the tool magazine and its precise coordination with the spindle through structural support and position adjustment.

[0003] In the existing tool magazine support structure design of dual-head machine tools, the traditional solution mostly adopts a split tool magazine bracket, that is, the tool magazine bracket and the column are independent components, which are assembled and fixed by bolts, positioning pins and other connecting parts.

[0004] However, the split structure leads to cumulative tolerances in the machining errors and assembly gaps of the various connecting surfaces, making it difficult to accurately control the position and movement trajectory of the tool magazine, directly affecting the dimensional accuracy of the machined parts. During installation and maintenance, it is necessary to align the installation references of multiple components such as the bracket, column, and tool magazine one by one, which is a complex and time-consuming process. Moreover, the split bracket requires additional splicing space, resulting in a loose overall layout of the machine tool. In addition, the tool magazine is installed at a relatively high height, shifting the center of gravity upwards, which significantly affects the impact and torque on the machine tool during operation and easily causes machining vibration.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dual-head integrated tool magazine support to solve the above problems.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a dual-head integrated tool magazine bracket, including a tool magazine bracket body, the tool magazine bracket body is an integrated structure and a reinforcing plate is provided in the middle, and a left tool magazine mounting position and a right tool magazine mounting position are provided on the tool magazine bracket body symmetrically distributed along the reinforcing plate.

[0008] The present invention is further configured such that: a central mounting hole is provided on the reinforcing plate, and lateral mounting holes are provided on both sides of the main body of the tool magazine bracket.

[0009] The present invention is further configured such that both the intermediate mounting hole and the lateral mounting hole are located at the end of the tool magazine bracket body away from the tool magazine.

[0010] The present invention is further configured such that: the middle mounting hole position has two rows of mounting holes, and the two rows of mounting holes are symmetrically arranged along the reinforcing plate.

[0011] The present invention is further configured such that a support partition is provided between the main body of the tool magazine bracket and the lateral mounting hole.

[0012] The present invention is further configured such that the main body of the tool magazine support is integrally cast from HT300 high-grade cast iron.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Firstly, the integrated structure has no assembly gaps and the increased contact area with the column can evenly bear the left and right torsional forces generated during the operation of the tool magazine, reduce local stress concentration, avoid bracket deformation, and ensure the long-term stability of the machine tool. Secondly, by eliminating the multi-component splicing process, the cumulative effect of gaps between connectors and machining errors of components is eliminated. The position accuracy of the tool magazine and the accuracy of the motion trajectory can be controlled within ±0.01mm, and the dimensional consistency and surface quality of the machined parts are significantly improved. Third, the tool magazine is located entirely on the machine bed, lowering the center of gravity by 25%-30% compared to traditional structures, thus reducing the impact and vibration of the tool magazine operation on the machine tool. At the same time, the integrated structure is integrated with the machine tool as a whole, allowing for the adaptation of motors with 20% increased power within the same space, thereby improving the machine tool's ability to process heavy-duty and high-speed parts.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Example

[0017] A dual-head integrated tool magazine support, such as Figures 1-2 As shown, the tool magazine support body 1 is a one-piece structure cast from HT300 high-grade cast iron. HT300 high-grade castings possess high strength and rigidity, better able to withstand the torque and vibration during tool magazine operation. Simultaneously, the casting process employs resin sand molding technology to ensure a smooth surface finish (Ra≤6.3μm) and dimensional tolerances, meeting the CT8 grade requirements of GB / T6414-2022. After casting, the part undergoes artificial aging treatment, i.e., holding at 200-220℃ for 8-10 hours, to eliminate internal stress. This prevents deformation of the support due to long-term stress or environmental changes, thus ensuring long-term stability of the machine tool's geometric accuracy, avoiding frequent downtime for adjustments due to accuracy degradation, extending equipment lifespan, and reducing equipment replacement and maintenance costs for enterprises.

[0018] The integrated structure eliminates the need for multiple component splicing steps, thus fixing the relative positions of the tool magazine, tool magazine support body 1, and column. This prevents tool magazine movement trajectory deviation caused by gaps during component splicing, ensuring precise positioning during tool changes and improving the dimensional accuracy of machined parts. Regarding machining safety: the absence of splicing links reduces loosening and abnormal noise during tool magazine operation, preventing tool magazine detachment or collision with the machine head due to excessive component gaps, reducing the risk of safety accidents during machining, and ensuring the safety of equipment and operators. By eliminating the cumulative effects of gaps in connecting parts and component machining errors, the tool magazine's positional accuracy and movement trajectory accuracy can be controlled within ±0.01mm, significantly improving the dimensional consistency and surface quality of machined parts.

[0019] Meanwhile, a reinforcing plate 2 is provided in the middle of the tool magazine support body 1. The tool magazine support body 1 is provided with a left tool magazine mounting position 3 and a right tool magazine mounting position 4 symmetrically distributed along the reinforcing plate. Thus, after fixing the tool magazine support body 1 to the column, it can be directly installed on the machine bed, and then the tool magazine and the machine head can be fixed. The number of parts is reduced by 60%, and the installation steps are simplified to less than 3 steps, avoiding equipment failure caused by improper installation and reducing labor costs.

[0020] Furthermore, the one-piece molded structure eliminates the need for frequent adjustments to the connectors, and the accuracy decay rate during long-term use is ≤0.005mm / year. The maintenance cycle is extended to more than 3 times that of traditional structures, reducing downtime for maintenance and improving production efficiency.

[0021] Meanwhile, the reinforcing plate 2 has a central mounting hole 5, and the tool magazine support body 1 also has lateral mounting holes 6 on both sides. The connection between the tool magazine support body 1 and the column is achieved through the central mounting hole 5 and the lateral mounting holes 6. The central mounting hole 5 has two rows of mounting holes, symmetrically arranged along the reinforcing plate 2. The combined area achieved by the central mounting hole 5 and the lateral mounting holes 6 is more than 30% larger than that of the traditional split structure. This allows it to evenly bear the lateral torque generated during tool magazine operation, increasing its maximum torsional moment by more than 40%, reducing local stress concentration, preventing support deformation, and ensuring the long-term stability of the machine tool.

[0022] A support partition 7 is provided between the main body 1 of the tool magazine bracket and the side mounting hole 6. The support partition 7 further enhances the overall torsional resistance, can evenly and well bear the left and right torsional force generated by the tool, reduce local stress concentration, and ensure stable accuracy over long-term use without frequent adjustments, ultimately helping to improve machining quality and production efficiency.

[0023] Furthermore, both the central mounting hole 5 and the lateral mounting hole 6 are located at the end of the tool magazine support body 1 furthest from the tool magazine. The entire tool magazine sits on the bed, and the center of gravity is lowered by 25%-30% compared to the traditional structure, reducing the impact and vibration of the tool magazine operation on the machine tool.

[0024] Meanwhile, the integrated structure is seamlessly integrated with the machine tool, optimizing the spatial layout and eliminating the need to reserve extra installation space for splicing the separate brackets. At the same time, this design allows for the installation of a more powerful motor in a limited space, enhancing the equipment's processing capabilities, such as handling harder materials and processing at higher speeds. This enables small and medium-sized enterprises to meet diverse processing needs through equipment upgrades without expanding their factory buildings, reducing the dual costs of site expansion and equipment replacement, and adapting to their "small space, high efficiency" production requirements.
