[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 9 As shown: A frame structure for a milling and turning tool magazine includes: a base 1, a support beam 2, a first connector 3, and a second connector 4; Base 1 is set on the working surface; The support beam 2 is vertically installed and is at least partially installed on the base 1. The support beam 2 adopts a steel structure. The first connector 3 and the second connector 4 are respectively disposed at both ends of the support beam 2; Two sprockets 5 are respectively mounted on the first connector 3 and the second connector 4, and are used to drive the tool magazine chain 6 to rotate.

[0025] Using structural steel as the main structure of the support beam 2, the structural steel is cut and directly used to process the support beam 2 during processing, which eliminates the complex casting, welding and large-area machining processes required for the integral frame or box frame in the existing technology, and significantly simplifies the manufacturing process.

[0026] By using structural steel as the main load-bearing component, only the first connecting piece 3 and the second connecting piece 4 need to be added at both ends to install the sprocket 5. This avoids the complex processing technology of the overall frame or box-type frame in the existing technology, making the overall structure simpler and more compact, reducing large-area casting or welding processing steps, and lowering manufacturing costs.

[0027] Since the sprocket 5 and the support beam 2 are installed separately through the first connector 3 and the second connector 4, it is not necessary to completely disassemble the support beam 2 when replacing the sprocket 5, bearings or maintaining the transmission mechanism, which improves maintenance efficiency and machine tool reliability.

[0028] As a preferred embodiment of the above, a first transition plate 21 is provided on the side of the support beam 2 near the first connector 3; The first transition plate 21 is provided with a first groove 211 and a second groove 212 that are perpendicular to each other; The first connector 3 is provided with a third groove 31 corresponding to the first groove 211 and a fourth groove 32 corresponding to the second groove 212; The first groove 211 and the third groove 31 are provided with a first positioning element to restrict the movement of the first connecting member 3 in the length direction; The second groove 212 and the fourth groove 32 are provided with second positioning members to restrict the movement of the first connecting member 3 in the width direction; The first transition plate 21 and the first connecting piece 3 are fixedly connected by the first locking piece.

[0029] By setting corresponding first grooves 211, second groove 212, third groove 31 and fourth groove 32 on the first transition plate 21 and the first connecting member 3, and cooperating with the first positioning member and the second positioning member, the connecting member can be effectively restricted in the length and width directions, ensuring the accuracy of the sprocket 5 installation position, thereby improving the stability of the tool magazine operation.

[0030] In this embodiment, a second transition plate 22 is provided on the side of the support beam 2 near the second connector 4; A fifth groove 221 is provided on the second transition plate 22 along the length of the support beam 2; The second connector 4 is provided with a sixth groove 41 corresponding to the fifth groove 221, and the length of the sixth groove 41 is greater than the length of the fifth groove 221; The fifth groove 221 and the sixth groove 41 are provided with a third positioning element to restrict the movement of the first connector 3 in the width direction; The second connector 4 is provided with a waist-shaped hole 42, and a second locking member connected to the second transition plate 22 is provided in the waist-shaped hole 42 for adjusting the center distance between the two sprockets 5.

[0031] In this embodiment, when it is necessary to adjust the distance between the two sprockets 5, the second locking member set on the second connecting member 4 can be loosened first; then the second connecting member 4 can be pushed to move along the length direction of the sixth groove 41, so that the second connecting member 4 moves closer or further away from the first connecting member 3, thereby realizing the fine adjustment of the distance between the two sprockets 5; after the adjustment is completed, the second locking member can be tightened again to reliably fix the second connecting member 4 in the required position; this structure makes the center distance adjustment process between the sprockets 5 simple and quick, and has high positioning accuracy, ensuring the stability of the tool magazine chain 6 transmission.

[0032] Among them, a third transition plate 23 is provided on the side of the support beam 2 near the base 1; The third transition plate 23 is provided with a seventh groove 231 along the length of the support beam 2; The base 1 is provided with an eighth groove 11 corresponding to the seventh groove 231; The seventh groove 231 and the eighth groove 11 are provided with a fourth positioning element to restrict the movement of the first connecting member 3 in the width direction; The third transition plate 23 and the base 1 are fixedly connected by a third locking member. In this embodiment, there are two third transition plates 23, or other numbers. Since the support beam 2 is relatively long, the connection between the two third transition plates 23 and the base 1 helps to increase the stability of the support structure.

[0033] In this embodiment, the support beam 2 is made of a U-shaped steel section, an I-shaped steel section, or an H-shaped steel section, at least one of these. In this embodiment, the support beam 2 is made of U-shaped steel section, which is cut and then a transition plate is welded to both ends. This method not only simplifies the processing technology of the support beam 2 and avoids the use of integral casting or complex welding structures, but also provides a reliable installation reference for the connecting parts after the transition plate is welded to the support beam 2. It should be noted that the use of steel sections with other cross sections is also within the scope of protection of this application.

[0034] As a preferred embodiment of the above, both the first connector 3 and the second connector 4 include a base plate 33 and a flange structure 34 disposed on the base plate 33 and protruding from the base plate 33. The flange structure 34 is provided with a mounting hole 341 for mounting a bracket, so that the bracket can be directly mounted on the connector, simplifying the connection between the bracket and the frame and reducing additional transition parts or processing steps.

[0035] The system also includes a fixed shaft 51 for connecting the first connector 3, the second connector 4, and the sprocket 5. The fixed shaft 51 has a base, and the base plate 33 has a countersunk hole 331. The fixed shaft 51 passes through the countersunk hole 331 and the sprocket 5. The base is located inside the countersunk hole 331 and is fixedly connected to the base plate 33 by a locking member. Specifically, the fixed shaft 51 cooperates with the sprocket 5 through the countersunk hole 331. During installation, the fixed shaft 51 only needs to be inserted and locked. When maintenance or replacement of the sprocket 5 is required, the locking member can be loosened for quick disassembly, which improves maintenance efficiency.

[0036] In this embodiment, a gap is provided between the end of the support beam 2 and the base 1, and one of the sprockets 5 is set in the gap. Specifically, this not only makes effective use of the structural space and reduces the overall volume occupied by the frame, but also makes the sprocket 5 more compactly arranged, which facilitates the arrangement and tensioning of the transmission tool magazine chain 6, thereby improving the overall structural rationality and operational stability of the tool magazine.

[0037] As a preferred embodiment of the above, the support beam 2 is provided with a through hole 24, which is used for the control wires of the sensor to pass through. The support beam 2 is also used to accommodate excess control wires. Specifically, the excess control wires are arranged inside the support beam 2 to make the external wiring simple and neat, and to avoid the messy wiring affecting the appearance of the frame and maintenance operations.

[0038] The base 1 has multiple support legs 12 at its bottom for adjusting balance. Specifically, the height of the support legs 12 can be finely adjusted according to the ground conditions at the installation site, so that the base 1 can be quickly leveled, improving the ease of installation of the equipment.

[0039] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
