DETAILED DESCRIPTION

[0027] The utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0028] In this embodiment, reference is made to Figures 1-7 ​​A multi-station five-axis numerical control machining platform, which is a specific implementation of the present application, comprises a fourth-axis overturning mechanism and a bridge plate 1, which is rotatably mounted on the fourth-axis overturning mechanism. The bridge plate 1 is provided with a plurality of fifth-axis rotating mechanisms. Each fifth-axis rotating mechanism comprises a rotating table 2 and a first angle limiting assembly 4. The bridge plate 1 is provided with a first bearing 1A that cooperates with the rotating table 2. The rotating table 2 is rotatably mounted on the upper end of the bridge plate 1 via a rotating shaft 3. The first angle limiting assembly 4 is arranged on the outer side of the rotating shaft 3. The rotating shaft 3 is provided with a gear 3A that cooperates with the first angle limiting assembly 4. The first angle limiting assembly 4 comprises a first driving member 4A and a gear block 4B and a gear rack 4C that respectively cooperate with the gear 3A. The gear rack 4C is slidably mounted on the outer side of the gear 3A. The gear block 4B is arranged on the output end of the first driving member 4A and slidably cooperates with the gear 3A.

[0029] The sliding cooperation between the gear rack 4C and the gear 3A enables the rotating table 2 to rotate and adjust the angle. When the rotating table 2 is rotated to the desired angle, the first driving member 4A can be used to push the gear block 4B to cooperate with the gear 3A, thereby firmly fixing the rotating table 2 and achieving precise angle positioning. The first driving member 4A can adopt a reciprocating driving mode such as a pneumatic cylinder or a linear motor, thereby controlling the sliding of the gear block 4B.

[0030] Furthermore, the gear rack 4C is provided with a limiting block 41C at each end. The limiting block 41C is integrally formed at each end of the gear rack 4C. The limiting block 41C can prevent the gear rack 4C from sliding excessively and thus causing the gear rack 4C to fall out of the meshing range of the gear 3A, thereby affecting the positioning accuracy of the rotating table 2. The integrally formed process makes the connection between the limiting block 41C and the gear rack 4C more secure, thereby reducing the faults caused by assembly problems. Figure 4 As shown in the drawings, the lower end of the bridge plate 1 is provided with a mounting seat 5 for mounting the gear rack 4C and the first driving member 4A. The mounting seat 5 is fixed on the lower end of the bridge plate 1 by bolts. The mounting seat 5 is connected by a plurality of plates. Furthermore, the number of the gear rack 4C and the gear block 4B is two. The gear rack 4C is arranged on both sides of the mounting seat 5, and the first driving member 4A is mounted on both ends of the mounting seat 5.

[0031] Furthermore, the rotating table 2 can be adjusted in angle in two ways, i.e., manually or by driving. When the rotating table 2 is driven to rotate, only one driving device needs to be installed on the mounting seat and connected with the gear rack 4C, and the sliding of the gear rack 4C can be accurately controlled by a control signal. When the rotating table 2 is manually rotated, the operator manually rotates the rotating table 2 to adjust the angle. The driving and manual rotating methods have their own advantages. The driving method is suitable for situations that require frequent adjustment and high-precision positioning, while the manual rotating method is suitable for debugging or infrequent operation scenarios. Furthermore, since the driving device is reduced, the cost of the equipment is also reduced. The two methods enable users to choose according to actual use requirements, thereby improving the flexibility and applicability of the machining platform.

[0032] In addition, the fourth axis overturning mechanism comprises a base 6, an oscillating cylinder 7 and a second angle limiting assembly 8 arranged on the base 6. The oscillating cylinder 7 and the second angle limiting assembly 8 are respectively connected with the two sides of the bridge plate 1, so that the oscillating cylinder 7 drives the bridge plate 1 to rotate. The second angle limiting assembly 8 comprises a second driving member 8A and a rotating disc 8B for synchronous rotation with the bridge plate 1. The second driving member 8A is arranged on one side of the rotating disc 8B. A plurality of limiting tooth portions 81B are arranged on the outer side of the rotating disc 8B. A limiting tooth cone 81A is arranged on the output end of the second driving member 8A and is matched with the limiting tooth portions 81B. One end of the base 6 is provided with a gas connection seat 10 for connecting with an external gas source. One side of the rotating disc 8B is provided with a detachable limiting stopper 82B. When the bridge plate 1 needs to be fixed in the process of carrying or placing in a warehouse, etc., the rotating disc 8B can be clamped by the limiting stopper 82B, so as to avoid unnecessary rotation of the bridge plate 1 due to vibration or accidental collision in the transportation process.

[0033] In the embodiment, the angle between the two adjacent limiting tooth portions 81B is 10 degrees, so that the adjustment angle of the rotating disc 8B is 10 degrees or an integer multiple thereof. In this way, it can meet the needs of various angles, thereby providing a highly customized solution for the user. In actual use, the user can select and replace the rotating disc 8B with different adjustment angles according to the specific needs. Such a design makes the adjustment of the rotation angle more flexible and diversified, and the user can easily adjust the bridge plate 1 to the best working angle according to different application scenarios and purposes.

[0034] In addition, the two sides of the base 6 are respectively provided with a support seat 6A. The support seat 6A is provided with a rotatable rotating seat 6B. One side of the rotating seat 6B is provided with a placing seat 6C connected with the bridge plate 1. The rotating disc 8B and the oscillating cylinder 7 are connected with the bridge plate 1 through the rotating seat 6B. The rotating seat 6B is rotatably installed on the support seat 6A through a second bearing 6D and is connected with the bridge plate 1 through the placing seat 6C. The rotating seat 6B is connected with the oscillating cylinder 7 and the rotating disc 8B through a connector 6E and an adjusting disc 6F, respectively. The second bearing 6D enables the rotating seat 6B to rotate flexibly, thereby ensuring the stability and accuracy of the bridge plate 1 at different angles.

[0035] The outer side of the oscillating cylinder 7 is provided with a third angle limiting assembly 9 matched with the rotating seat 6B. The third angle limiting assembly 9 comprises a gear position disc 9A and a plurality of third driving members 9B. The output end of the third driving member 9B is provided with a latch 9C matched with the gear position disc 9A.

[0036] In this embodiment, four third driving elements 9B are provided, which are distributed in four directions on the outer circumference of the swing cylinder 7. The four third driving elements 9B are sequentially divided into a first driving element 91B, a second driving element 92B, a third driving element 93B, and a fourth driving element 94B. The gear shift plate 9A is installed on the side of the rotary seat 6B near the swing cylinder 7.

[0037] like Figure 7 As shown, the gear shift plate 9A is provided with a gear shift groove, which has an inner groove 91A and an outer groove 92A. Both the inner groove 91A and the outer groove 92A have an included angle of 90 degrees. The first drive element 91B cooperates with the inner groove 91A through a pin 9C, and the second drive element 92B and the third drive element 93B cooperate with the outer groove 92A through pins 9C, allowing for fixed angle restrictions of 90 degrees, 180 degrees, and 270 degrees. When a 90-degree rotation is required, the gear shift groove is restricted by the pins 9C on the first drive element 91B and the second drive element 92B. At the same time, the pins 9C on the third drive element 93B and the fourth drive element 94B are retracted to avoid affecting the rotation of the bridge plate 1. When a 180-degree or 270-degree angle rotation is required, the pins 9C on the first, second, and fourth drive elements 94B are retracted, and the gear shift groove is restricted by the pin 9C on the third drive element 93B. Furthermore, when rotating 180 degrees, adjustment must be completed by rotating in the opposite direction.

[0038] The gear shift plate 9A is also provided with three tapered holes 93A that cooperate with the fourth drive element 94B. The tapered holes 93A are arranged around the gear shift plate, forming an included angle of 120 degrees between them. In use, the pin 9C on the output end of the fourth drive element 94B can be pushed to cooperate with the tapered holes 93A to lock the tilt angle of the bridge plate 1.

[0039] The arrangement of the first drive element 91B, the second drive element 92B, the third drive element 93B, and the fourth drive element 94B allows the user to quickly adjust the bridge plate 1 to the commonly used tilt angle during operation, thereby improving work efficiency. When using the third drive element 9B, the fixing block on the second drive element 8A must be retracted to avoid affecting the rotation of the bridge plate 1. Similarly, when using the second drive element 8A, the pins 9C on the third drive element 9B must be fully retracted. Furthermore, the included angle between the inner groove 91A and the outer groove 92A can be 30 degrees or 45 degrees. In actual use, different angled stop plates 9A can be replaced according to different requirements to adapt to different rotation angle needs.

[0040] The utility model discloses beneficial effect: through the cooperation of fourth axis turnover mechanism and a plurality of fifth axis rotating mechanism, make one processing can clamp multiple parts simultaneously, and every part can realize multi -angle inclination to meet the processing demand.
