Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Figure 1 shows a structural schematic diagram of the tool turret machine with a guide rail in the present utility model, Figure 2 shows a side view of the tool turret machine with a guide rail in the present utility model, Figure 3 shows a cross-sectional view of the tool turret machine with a guide rail in the present utility model. The tool turret machine with a guide rail includes: a moving guide rail 1 and a tool turret body 2. The moving guide rail 1 is located above the tool turret body 2. The moving guide rail 1 includes an upper moving sub-guide rail and a lower moving sub-guide rail.

[0028] One or more connecting blocks 3 are arranged on the moving guide rail 1. The connecting block 3 is connected to the functional part 4. The connecting block 3 is driven by the first driving motor 5 to move on the moving guide rail 1. In this embodiment, four connecting blocks 3 are arranged on the moving guide rail 1. Two of the four connecting blocks 3 are correspondingly arranged on the upper moving sub-guide rail, and two of the four connecting blocks 3 are correspondingly arranged on the lower moving sub-guide rail. One or more fixing plates are arranged on the connecting block 3. The fixing plate is used to fix the functional part 4 on the connecting block 3, ensuring that when the connecting block 3 is driven by the first driving motor 5 to move, it can drive the functional part 4 to move, thereby changing the position of the functional part 4 to adapt to various environments.

[0029] The turret body 2 includes a turret head 21 and more than one tool holder 22. Any one of the tool holders 22 is installed on the turret head 21. The turret head 21 is driven by a driving mechanism 6 to move left and right in the horizontal direction, and the turret head 21 is driven by the driving mechanism 6 to rotate around its geometric center. It should be noted that in this embodiment, the turret body 2 includes twelve tool holders 22, but the number of tool holders 22 can be increased or decreased according to actual situations. For example, the number of tool holders 22 on the turret body 2 can be increased to eighteen or even more tool holders 22.

[0030] Further, the driving mechanism 6 includes a first driving cylinder 61 and a second driving motor 62. A moving part 7 is arranged at the output end of the first driving cylinder 61, and a rotating part 8 is arranged at the output end of the second driving motor 62. When the output end of the first driving cylinder 61 starts to move, it drives the moving part 7 to move left and right in the horizontal direction, thereby changing the working position of the moving part 7; when the output end of the second driving motor 62 starts to rotate, it drives the rotating part 8 to rotate around its geometric center, thereby driving the rotation to a specified angle.

[0031] Still further, the moving part 7 is connected to the turret head 21, and the rotating part 8 is connected to the turret head 21; the turret head 21 is driven by the moving part 7 to move left and right in the horizontal direction, and the turret head 21 is driven by the rotating part 8 to rotate around its geometric center. The moving part 7 is used to convert the turret head 21 from the locked position to the rotatable position or from the rotatable position to the locked position. The rotating part 8 is used to drive the turret head 21 to rotate a specified angle, so that the required tool holder 22 and tool rotate to the specified position for processing.

[0032] Further, the moving part 7 includes a driven gear 71, and the rotating part 8 includes a driving gear 81. The driving gear 81 meshes with the gear; the thickness of the driving gear 81 is D1, and the thickness of the driven gear 71 is D2. The constraint relationship between D1 and D2 is D1 > D2. When the driving gear 81 rotates, it drives the driven gear 71 to rotate, and the driven gear 71 drives the turret head 21 to rotate, so that the turret head 21 rotates a specified angle to rotate the required tool to the tool setting position. The thickness of the driving gear 81 is greater than the thickness of the driven gear 71, which ensures that the driven gear 71 moves after being driven by the moving part 7 and remains meshed with the driving gear 81, avoiding the situation that the driven gear 71 has no contact with the driving gear 81 after displacement, which is beneficial to the smoothness and stability of the tool changing function of the turret.

[0033] Furthermore, a lubricating coating is provided on the surface of the driving gear 81, and a lubricating coating is provided on the surface of the driven gear 71. The main function of the lubricating coating is to reduce the direct contact between the driving gear 81 and the driven gear 71, reduce the friction and wear between the driving gear 81 and the driven gear 71, and extend the service life of the driving mechanism 6. Secondly, a large amount of heat will be generated due to friction during the use of the driving gear 81 and the driven gear 71. The lubricating coating can absorb and carry away this heat, thereby reducing the temperature of the equipment and preventing damage caused by overheating.

[0034] Furthermore, the functional part 4 includes: a sliding tool magazine, on which a plurality of tool position grooves are provided, and a tool holder is provided on any one of the tool position grooves. The sliding tool magazine is used to store more tools, enabling the turret lathe to meet the cutting requirements of different shapes and improving the flexibility of the turret lathe; the sliding tool magazine enables the turret lathe to perform automatic tool change operations, significantly reducing the time and cumbersome process of manual tool change and improving production efficiency; finally, the sliding tool magazine helps the turret lathe to switch tools of different shapes, reducing the non-cutting time during production and improving production efficiency.

[0035] Furthermore, any one of the tool position grooves is provided with a number, and the number corresponds to the tool position groove one by one, that is, each number corresponds to the tool in the tool position groove, enabling the operator to quickly obtain the relevant information of the tool according to the number, thereby selecting the tool required during the processing and saving the time for selecting and using the tool on site; secondly, by numbering the tools, the real-time monitoring of the tool usage situation can be realized, and potential safety problems can be discovered and solved in time.

[0036] Furthermore, the functional part 4 includes: a fixed power head and a grinding head spindle. The grinding head spindle is inserted into the fixed power head, and the fixed power head and the grinding head spindle are used in combination to provide cutting force and rotational speed, so that the workpiece can be precisely processed. When the functional part 4 is a fixed power head and the grinding head spindle, the functional part 4 can feed simultaneously with the tool on the tool disc 21, and both process the workpiece at the same time, reducing the processing time and thus improving the processing efficiency.

[0037] It should be noted that the functional part 4 can not only be a sliding tool magazine alone or a fixed power head and a grinding head spindle alone, but also both can be arranged on the moving guide rail 1, making the turret have more diverse functions.

[0038] Further, a plurality of fixing holes 211 are provided on the cutter head 21, and the fixing holes 211 are distributed on the side surface of the cutter head 21 according to a preset position. In this embodiment, four fixing holes 211 are provided at the position of the side surface of the cutter head 21 corresponding to each cutter position groove. The four fixing holes 211 are used to fix the required cutting tools. The four fixing holes 211 can fix the workpiece or the mold on the corresponding workbench or machine, effectively preventing it from shifting or rotating during the machining process, ensuring that the cutting tool remains connected to the cutter head 21 during use, and reducing the risk of the cutting tool shifting during use and causing a decrease in accuracy.

[0039] The present utility model further provides a numerical control machine tool. The numerical control machine tool includes a turret lathe with a guide rail and a machining area as described above. The turret lathe with a guide rail is located inside the numerical control machine tool, and the turret lathe with a guide rail is located above the machining area. The turret lathe with a guide rail being located above makes it easier for the cutting tool to approach the workpiece, thereby reducing the additional movement time caused by the excessive distance between the cutting tool and the workpiece during the machining process. Secondly, the turret lathe is located above the machining area, which helps to reduce the machining errors caused by the vibration or deformation of the machine tool. The relative position between the cutting tool and the workpiece is more stable, and the machining accuracy is correspondingly improved.

[0040] In summary, the present utility model realizes different functions of the turret by setting a moving guide rail, providing connection blocks on the moving guide rail, and arranging different functional parts on the connection blocks, thereby improving the flexible manufacturing of the turret. The present utility model also provides a first driving motor. When the connection block is driven by the first driving motor to move, it can drive the functional part to move along the moving guide rail, thereby changing the position of the functional part to adapt to various environments.

[0041] In addition, the above has introduced in detail a turret lathe with a guide rail and a numerical control machine tool provided by the embodiments of the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
