[0035] Please refer to Figure 1-6 , a shaft core processing device, including a machine body 1. A base 101 and a cutting mechanism 102 are provided on the machine body 1. A cutting table 103 is installed on the base 101, and a shaft core part 104 is provided on the cutting table 103. There are no less than three groups of fixing frames 106 arranged on the cutting table 103. A shaft rod 108 is provided inside the fixing frame 106, and a positioning plate 107 is provided at one end of the shaft rod 108. An extrusion spring 109 is provided between the positioning plate 107 and the fixing frame 106.

[0036] The following will, with reference to the drawings, elaborate on some embodiments of this application in detail:

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, the shaft core processing device of the present application is mainly a processing device composed of a machine body 1, a base 101, a cutting mechanism 102, a cutting table 103, a shaft core part 104 and other structures. Among them, the base 101 is installed on the machine body 1, and the cutting mechanism 102 is located above the base 101. The cutting tool carried at the bottom of the cutting mechanism 102 performs cutting operations on the shaft core part 104 placed on the cutting table 103. During the cutting process, there are no less than three fixing brackets 106 arranged in a circumferential array on the top of the cutting table 103, so that the movable space inside the fixing bracket 106 is circular. At this time, a positioning plate 107 is provided inside each fixing bracket 106, so that the positioning plate 107 surrounds the outer circle of the shaft core part 104. Among them, a shaft rod 108 is connected to the positioning plate 107. One end of the shaft rod 108 is connected to the positioning plate 107, and the other end can move horizontally along the inside of the fixing bracket 106. A compression spring 109 provided between the fixing bracket 106 and the positioning plate 107 surrounds the shaft rod 108. Therefore, during the processing, according to the size of the shaft core diameter, by moving the positioning plate 107 towards one end away from or close to the shaft core part 104, if the compression spring 109 is compressed, when the shaft rod 108 moves towards one end of the fixing bracket 106, the fixed interval is enlarged. After the shaft core part 104 is placed on the support bottom plate 105 and inside the positioning plate 107, the acting force is stopped. After the compression springs 109 at each position generate elastic deformation and drive the positioning plate 107 to return to its original state, the workpiece is fixed. Through this fixing method, while improving the operation convenience, it can also avoid the problem of operation jamming caused by the internal thread rusting and not being processed during long-term application.

[0038] Among them, the inner end face of the positioning plate 107 is provided with a radian that fits the outer wall of the shaft core part 104, so that the positioning plate 107 completely fits the outer circle of the shaft core part 104, so as to improve the stability during the fixing process.

[0039] In some embodiments, a support bottom plate 105 is placed flat at the bottom of the inner end of the fixing bracket 106, so that it is between the positioning plate 107 and the fixing bracket 106. The shaft core part 104 is placed on the support bottom plate 105 to support its bottom. The diameter of the support bottom plate 105 is designed to be smaller than the inner circle surrounding size of the fixing bracket 106 and not less than the diameter size of the shaft core part 104.

[0040] It should also be noted that the support base plate 105 is connected to the cutting table 103 through a lifting structure, and at the same time, the height of the support base plate 105 at the inner end of the fixing frame 106 is adjusted to a certain extent. The lifting structure is a combined application of a threaded rotating rod 202 and a lifting bracket 203. One end of the threaded rotating rod 202 is vertically movably installed on the cutting table 103 through a bearing, and the lifting bracket 203 is installed at one end of the support base plate 105, and the other end is threadedly connected to the threaded rotating rod 202. By rotating the handle of the threaded rotating rod 202, while driving the threaded rotating rod 202 to rotate, the support base plate 105 can move up and down inside the space with a gap between the fixing frame 106 and the positioning plate 107, so as to adjust the height of the support base plate 105 for mounting the shaft core member 104 to a certain extent.

[0041] Please refer to Figure 3 、 Figure 4 and Figure 5 , in this application, a sleeve plate 110 and a stabilizing rod 111 are also provided. The sleeve plate 110 is symmetrically installed on both sides of the support base plate 105, and the stabilizing rod 111 is installed on both sides of the top of the cutting table 103. During application, the sleeve plate 110 is correspondingly slidably connected to the stabilizing rod 111, so that when the support base plate 105 moves up and down, its overall stability can be improved.

[0042] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , in this application, a sleeve 2 is also provided. One end of the shaft rod 108 away from the positioning plate 107 extends outside the fixing frame 106 and has a thread. A sleeve 2 is threadedly sleeved on the outside of this threaded section to lock the shaft rod 108. When the sleeve 2 is disassembled and separated from the threaded section of the shaft rod 108, it can be pulled inward to separate it together with the positioning plate 107 from between the fixing frame 106 for disassembly operation. At the same time, the positioning plate 107 can be replaced according to the usage requirements to improve applicability.

[0043] This application also provides an end pad 201. The inner end face of the sleeve 2 is designed with a rubber material. When the sleeve 2 is rotated on the threaded section of the shaft rod 108, the end pad 201 presses against the outer wall of the fixing frame 106. The outer wall of the fixing frame 106 is flat. After the two come into contact, the friction force of the contact surface can be increased, making the connection more stable.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the said principles, the embodiments of the present invention can have any deformation or modification.
