[0001] The utility model relates to the technical field of connecting shaft processing, in particular to a fixing device for processing and fixing a connecting shaft of a warp knitting machine. Background Technique

[0002] In a warp knitting machine, the connecting shaft not only bears the important task of connecting and supporting rotating parts, but also is responsible for transmitting power to ensure the smooth operation of the entire warp knitting machine mechanical system. When designing the structure of the connecting shaft, it usually needs to be customized according to its specific functions and requirements in the warp knitting machine. Key grooves are provided on the shaft body of the connecting shaft to cooperate with the keys on the rotating parts to achieve precise transmission. When opening the key grooves, a tooling is required to fix the connecting shaft.

[0003] Common fixing devices for processing connecting shafts mainly include a machine table, and at least two clamps are provided on the machine table. The two clamps can fix the shaft from both ends of the shaft. The clamps are divided into fixed clamps and movable clamps. The movable clamp includes two jaws that can move on the machine table. When processing the connecting shaft, the driving parts on the machine table will drive the two jaws to move closer to the shaft direction to fix the shaft body in the middle. Therefore, the connecting shaft is generally only limited from both sides of its shaft body. During the grooving process, the tool often grooves from the top of the shaft body. When the shaft body is impacted by the tool, it will produce a slight up-and-down swing, which will affect the machining accuracy of the shaft body. Content of the Utility Model

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0022] According to Figure 1 、 2 As shown in FIGS. 1, 2 and 3, a fixing device for processing a connecting shaft of a warp knitting machine is proposed in this embodiment, which includes a bottom frame 1. Two bases 2 are provided at the upper end of the bottom frame 1. A first support column 6 and a second support column 7 are provided at the upper end of the base 2. Both the first support column 6 and the second support column 7 are fixedly connected to the base 2;

[0023] The upper end of the first support column 6 is provided with a first V-fork 8. The first V-fork 8 is fixedly connected to the first support column 6. One end of the first V-fork 8 far from the first support column 6 is fixedly connected to the side of the second support column 7 facing the first support column 6; The connecting shaft to be processed is placed on the upper end of the first V-fork 8. The first support column 6 and the second support column 7 cooperate with the first V-fork 8 to support the connecting shaft from both ends of the connecting shaft.

[0024] Two second V-forks 9 are provided above the first V-fork 8. The two second V-forks 9 are slidably arranged on the left and right sides of the second support column 7. The two second V-forks 9 are staggered from the first V-fork 8 and the first support column 6. The upper end of the second support column 7 is provided with a lifting mechanism for adjusting the height of the second V-fork 9. The lifting mechanism is detachably connected to the second V-fork 9. The lifting mechanism pushes the second V-fork 9 to fall. After the second V-fork 9 falls, it presses both ends of the connecting shaft. The first V-fork 8 and the second V-fork 9 surround the connecting shaft, and can limit the connecting shaft from multiple directions. During the processing, the shaft body will not shift. The structural design in which the second V-fork 9 is staggered from the first V-fork 8 enables the second V-fork 9 to fix connecting shafts of different diameters after falling, and has a wide range of applications.

[0025] For the specific structure of the lifting mechanism, please refer to the following description.

[0026] The lifting mechanism includes a slider 11 and a hydraulic push rod 12. The slider 11 is slidably connected in a chute 10 opened at the upper end of the second support column 7. The installation end of the hydraulic push rod 12 is fixedly connected to the upper end of the second support column 7. The output end of the hydraulic push rod 12 is inserted into the chute 10 and fixedly connected to the upper end of the slider 11. The second V-shaped fork 9 is detachably connected to the slider 11.

[0027] The working principle of the lifting mechanism is that the height of the slider 11 is controlled by the hydraulic push rod 12. The chute 10 guides the slider 11 by cooperating with the slider 11. The two second V-shaped forks 9 are installed on the left and right sides of the slider 11. When the slider 11 descends, the second V-shaped forks 9 will also descend, and cooperate with the first V-shaped fork 8 to fix the connecting shaft to be processed. The detachable installation method of the second V-shaped fork 9 and the slider 11 facilitates the staff to replace the bent second V-shaped fork 9.

[0028] It should be further noted that grooves 13 are provided on both the left and right sides of the slider 11. The two second V-shaped forks 9 are respectively clamped into the two grooves 13. A threaded rod 16 is assembled at the upper end of the slider 11. The threaded rod 16 vertically penetrates the bottom frame 1 and the second V-shaped fork 9. Fastening nuts 17 are provided at the upper and lower ends of the threaded rod 16. The fastening nuts 17 are threadedly connected to the threaded rod 16. When removing the second V-shaped fork 9 from the left and right sides of the slider 11, the fastening nuts 17 at the upper and lower ends of the threaded rod 16 are screwed out. After releasing the limit of the fastening nuts 17 on the threaded rod 16, the threaded rod 16 can also be pulled out from the slider 11. At this time, the second V-shaped fork 9 can be directly removed from the groove 13.

[0029] Preferably, rubber gaskets are also provided at the upper and lower ends of the threaded rod 16. The gaskets are placed between the slider 11 and the fastening nuts 17. By providing gaskets between the slider 11 and the fastening nuts 17, the pressure in the contact area between the fastening nuts 17 and the slider 11 is shared, while improving the fastening degree of the fastening nuts 17, protecting the stressed sides of the fastening nuts 17 and the slider 11.

[0030] During the process of fixing the second V-shaped fork 9 into the groove 13, the second V-shaped fork 9 will slide along the groove 13. Therefore, it will be inconvenient for the staff to assemble the threaded rod 16 on the slider 11 and the second V-shaped fork 9. In the preferred solution, a limiting edge 15 is provided on the groove surface of the groove 13, and a guiding edge 14 is provided on the outer side wall of the second V-shaped fork 9. The limiting edge 15 is fixedly connected to the slider 11, and the limiting edge 15 is snapped into the guiding edge 14 and is slidably connected to the guiding edge 14. Before inserting the second V-shaped fork 9 into the groove 13, it is necessary to align the limiting edge 15 on the groove 13 with the guiding edge 14 on the outer side wall of the second V-shaped fork 9 first. The guiding edge 14 will cooperate with the limiting edge 15 to limit the second V-shaped fork 9 from sliding obliquely along the groove 13. While facilitating the assembly of the threaded rod 16, the fit between the slider 11 and the second V-shaped fork 9 is increased.

[0031] To facilitate the staff to disassemble and replace each group of frame structures, in a relatively good implementation manner, a bolt plate 3 is provided at the lower end of the base 2. The bolt plate 3 is fixedly connected to the base 2. Fixed bolts 4 are assembled at both ends of the bolt plate 3. The fixed bolts 4 pass through the bolt plate 3 and are threadedly connected to the positioning holes 5 opened at the upper end of the bottom frame 1. The base 2 and the bottom frame 1 are fixed by means of bolt connection. When removing the base 2 from the upper end of the bottom frame 1, the fixed bolts 4 at the upper end of the bolt plate 3 can be screwed out from the positioning holes 5 opened at the upper end of the bottom frame 1.

[0032] Furthermore, there are several positioning holes 5 at the upper end of the bottom frame 1, and each positioning hole 5 is evenly arranged along the length direction of the bottom frame 1. The advantage of this design is that by adjusting the fixed position of the bolt plate 3, the distance between the two groups of frame structures can be adjusted, so as to meet the processing requirements of connecting shafts of different lengths, and the applicable range is wider.

[0033] The working principle of this application:

[0034] The connecting shaft to be processed is placed on the upper end of the first V-shaped fork 8, and the first support column 6 and the second support column 7 cooperate with the first V-shaped fork 8 to support the connecting shaft from both ends of the connecting shaft.

[0035] The lifting mechanism pushes the second V-shaped fork 9 to drop. After the second V-shaped fork 9 drops, it presses both ends of the connecting shaft. The first V-shaped fork 8 and the second V-shaped fork 9 surround the connecting shaft, and can limit the connecting shaft from multiple directions. During the processing, the shaft body will not shift. The structural design in which the second V-shaped fork 9 is staggered from the first V-shaped fork 8 enables the second V-shaped fork 9 to fix connecting shafts of different diameters after dropping, and the applicable range is wide.
