[0028] Embodiment 1

[0029] Referring to Figures 1 - 4 , a machine tool for nut processing, including an operating table 1, a support disk 8 is fixed at the top of the operating table 1, a placement table 5 is rotatably connected to the top of the support disk 8, a limiting groove 6 is opened inside the placement table 5, the inner side of the limiting groove 6 is in a snowflake shape, a support 10 is fixed at the top of the placement table 5, a lead screw 12 is rotatably connected to the bottom end inside the support 10, a threaded disk 13 is threadedly connected to the outside of the lead screw 12, several linkage rods 14 are rotatably connected to the outside of the threaded disk 13, and several sliding clamping blocks 15 are slidably connected to the inner side of the limiting groove 6 and away from one end of the lead screw 12, the right end of the sliding clamping block 15 is rotatably connected, a second servo motor 11 is fixed at the top of the support 10, and the output end of the second servo motor 11 passes through the support 10 and is fixed to the lead screw 12;

[0030] Specifically, the prior art is not convenient for processing and producing different models of sizes, which leads to a single product situation in the production process of the prior art. When the device processes nuts of different sizes, at this time, several nuts are placed together inside the limiting groove 6, and the second servo motor 11 is started to drive the lead screw 12 to rotate, so that the lead screw 12 drives the threaded disk 13 to move up and down reciprocally. Furthermore, when the threaded disk 13 moves upward, it drives the linkage rod 14 to squeeze the sliding clamping block 15, and then the sliding clamping block 15 limits and fixes several nuts along the inside of the limiting groove 6, which is convenient for limiting and processing nuts of different size models, thereby increasing the practicability of the device;

[0031] A second buffer member 17 is assembled at the left end of the sliding clamping block 15, and several first buffer members 16 are assembled at the inner side of the limiting groove 6 and away from one end of the lead screw 12;

[0032] Specifically, when the sliding clamping blocks 15 slide in the direction away from each other, at this time, the sliding clamping blocks 15 drive the second buffer member 17 to move in the direction of the first buffer member 16, so that the sliding clamping blocks 15 drive the second buffer member 17 to limit the nuts, and the first buffer member 16 and the second buffer member 17 effectively protect the nuts;

[0033] A first servo motor 3 is fixed at the top of the operating table 1, a transmission gear 4 is fixed at the output end of the first servo motor 3, a meshing tooth 9 is fixed on the outside of the placement table 5, and the outside of the transmission gear 4 is meshed and connected with the meshing tooth 9;

[0034] Specifically, when several nuts are limited by the sliding clamp block 15, the servo motor 1 is started at this time to drive the transmission gear 4 to rotate. The transmission gear 4 drives the placement table 5 and the support disk 8 to rotate, so that each nut can be effectively processed, thereby improving the efficiency of nut processing;

[0035] A storage box 7 is slidably connected inside the operating table 1 and below the support disk 8. A support frame 2 is fixed to one side of the top of the operating table 1. A telescopic grinding assembly is arranged above the placement table 5 on one side of the support frame 2. After the nuts inside the limiting groove 6 are processed by the telescopic grinding assembly, the servo motor 2 is started at this time to drive the lead screw 12 to rotate. The lead screw 12 drives the threaded disk 13 to move downward. The threaded disk 13 drives the linkage rod 14 to move the sliding clamp block 15 and the buffer 2 17 in the direction of approaching each other, so that the sliding clamp block 15 drives the buffer 2 17 to disengage from the nut. Therefore, the nut falls from between the buffer 1 16 and the buffer 2 17 into the storage box 7, which is convenient for collecting the processed nuts;

[0036] In this embodiment, the telescopic grinding assembly is an existing and mature technology that has been publicly disclosed. The present invention will not describe it in detail here, nor is it the main innovation direction of the present invention.

[0037] The use process of a nut processing machine tool provided by the present invention is as follows:

[0038] Working principle: When in use, when several nuts are placed together inside the limiting groove 6, the servo motor 2 is started to drive the lead screw 12 to rotate, so that the lead screw 12 drives the threaded disk 13 to reciprocate upward or downward. Further, when the threaded disk 13 moves upward, it drives the linkage rod 14 to squeeze the sliding clamp block 15. Then, the sliding clamp block 15 limits and fixes several nuts along the inside of the limiting groove 6, which is convenient for limiting and processing nuts of different sizes and models;

[0039] Secondly, the servo motor 1 is started to drive the transmission gear 4 to rotate. The transmission gear 4 drives the placement table 5 and the support disk 8 to rotate, so that each nut can be effectively processed. When several nuts are processed, conversely, the servo motor 2 drives the lead screw 12 to rotate. The lead screw 12 drives the threaded disk 13 to move downward. The threaded disk 13 drives the linkage rod 14, the sliding clamp block 15 and the buffer 2 17 to move in the direction of approaching each other, so that the buffer 2 17 disengages from several nuts. Therefore, several nuts fall from between the buffer 1 16 and the buffer 2 17 into the storage box 7, which is convenient for collecting the processed nuts.
