DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a multi-station four-axis fixture, including a fixed frame 1. Two mounting flanges 4 are installed on the inner wall of the fixed frame 1. One end of the two mounting flanges 4 away from the fixed frame 1 is fixedly connected to a main body 13, and the main body 13 is set to be square. Each side of the main body 13 is fixedly connected to a mounting base 5. A first row of equally spaced card slots 6 is provided on the surface of the mounting base 5. A rotating shaft 3 is rotatably connected inside the fixed frame 1, that is, the rotating shaft 3 of the four-axis machining center, used to drive the workpiece to rotate. One end of the rotating shaft 3 is fixedly connected to the mounting flange 4, and the end of the rotating shaft 3 away from the fixed frame 1 is connected to a driving device. A workpiece plate 10 to be processed is inserted into the first row of card slots 6.

[0024] When the device drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the mounting flange 4 to rotate. The mounting flange 4 drives the main body 13 to rotate. The main body 13 drives the mounting base 5 to rotate. The mounting base 5 drives the workpiece plate 10 inserted into the first row of card slots 6 to rotate. Thus, by driving the rotating shaft 3 to rotate through the device, the position of the workpiece plate 10 on the main body 13 is changed, enabling the parts on the other side of the main body 13 to be processed. Therefore, when the device is in use, only by driving the rotating shaft 3 can the position of the workpiece plate 10 be changed, avoiding frequent material replacement and long downtime, greatly improving production efficiency. At the same time, it avoids the operation where only one workpiece can be installed and processed at a time for the staff, facilitating the use of the staff and reducing the labor burden of the staff.

[0025] The workpiece plate 10 to be processed is set to be square, and the first row of card slots 6 is also set to be square. When the workpiece plate 10 is inserted into the first row of card slots 6, the insertion position of the workpiece plate 10 is positioned, avoiding the situation of deviation during the insertion process of the workpiece plate 10.

[0026] The surface of the installation base 5 is fixedly connected with a fixed frame 11. The inner wall of the fixed frame 11 is slidably connected with a rack 8. One end of the rack 8 is rotatably connected with a first threaded rod 7. The surface of the first threaded rod 7 is threadedly connected with the inside of the fixed frame 11. The inside of the fixed frame 11 is rotatably connected with a rotating rod 12. The surface of the rotating rod 12 is fixedly connected with a gear 9. The surface of the rack 8 is meshed with the surface of the gear 9. An adjusting rod 2 is slidably connected inside the rotating rod 12. The adjusting rod 2 is arranged in a regular pentagon shape. One end of the adjusting rod 2 located outside the rotating rod 12 is fixedly connected with a second threaded rod 14. The surface of the second threaded rod 14 is threadedly connected with the inside of the installation base 5. One end of the second threaded rod 14 away from the adjusting rod 2 is rotatably connected with a clamping block 15. The surface of the clamping block 15 is fixedly connected with a convex rod. The clamping block 15 is slidably connected with the inside of the installation base 5. There are holes on the surface of the plate to be processed 10. The convex rod of the clamping block 15 matches the size of the holes on the surface of the plate to be processed 10.

[0027] When the plates to be processed 10 are inserted into the first clamping grooves 6 on the surface of the installation base 5, the worker rotates the first threaded rod 7. Thus, the first threaded rod 7 moves into the inside of the fixed frame 11. The sliding of the first threaded rod 7 pushes the rack 8. The movement of the rack 8 drives the gear 9 to rotate. The gear 9 drives the rotating rod 12 to rotate. And because the adjusting rod 2 is arranged in a pentagon shape, the rotating rod 12 drives the adjusting rod 2 to rotate. The adjusting rod 2 drives the second threaded rod 14 to rotate. Thus, the second threaded rod 14 rotates and continuously moves into the inside of the installation base 5. As a result, the second threaded rod 14 pushes the clamping block 15, so that the clamping block 15 is inserted into the inside of the plate to be processed 10 to fix it. After the plate to be processed 10 is processed, when the device is disassembled from the fixing frame 1, at this time, the worker reverses the first threaded rod 7, which causes the first threaded rod 7 to drive the rack 8 to move. Thus, the rotating rod 12, the gear 9, the adjusting rod 2, and the second threaded rod 14 reverse, so that the clamping block 15 slides out of the inside of the plate to be processed 10 and no longer fixes it. At this time, the installation base 5 is located below the device, resulting in the plate to be processed 10 sliding out of the inside of the first clamping groove 6, avoiding the operation of the worker to disassemble it, thus reducing the labor burden of the worker and facilitating the worker to use.

[0028] Working principle: When the device drives the rotary shaft 3 to rotate, the rotary shaft 3 drives the mounting flange 4, the main body 13, and the mounting base 5 to rotate. The mounting base 5 drives the workpiece plate 10 inserted into the first card slot 6 to rotate. Furthermore, by driving the rotary shaft 3 to rotate, the position of the workpiece plate 10 on the main body 13 is changed. When the workpiece plates 10 are inserted into the first card slots 6 on the surface of the mounting base 5, the staff rotates the first threaded rod 7. Thus, the first threaded rod 7 moves into the fixed frame 11. The sliding of the first threaded rod 7 pushes the rack 8. The movement of the rack 8 drives the gear 9 to rotate. The gear 9 drives the rotating rod 12 to rotate. And because the connecting rod 2 is pentagonal, the rotating rod 12 drives the connecting rod 2 to rotate. The connecting rod 2 drives the second threaded rod 14 to rotate. Thus, the second threaded rod 14 rotates and continuously moves into the mounting base 5. As a result, the second threaded rod 14 pushes the clamping block 15, making the clamping block 15 insert into the workpiece plate 10 to fix it.

[0029] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
