[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] In the embodiment, Figure 1-3 A sleeve chamfering device is provided, comprising a processing table 1, the table top of the processing table 1 is inclined, a fixed seat 2 is arranged on the processing table 1, a feeding channel 3 adapted to the sleeve is opened on the fixed seat 2, a lifting platform 4 is arranged on the table top of the processing table 1, an electric drill 5 is arranged at the movable end of the lifting platform 4, a chamfering drill bit 6 adapted to the sleeve is arranged at the output end of the electric drill, a clamping assembly 7 for fixing the sleeve is arranged on the processing table 1, a limiting assembly 8 is arranged at the movable end of the lifting platform 4, which is used to position the next sleeve to be processed, the table top of the processing table 1 is inclined, so that the whole device can use gravity to help the transmission of the sleeve when working, and the sleeve located in the feeding channel 3 will be closely connected, and the clamping assembly 7 will fix the sleeve in the processing position when it is opened, and the sleeve can be chamfered by cooperating with the electric drill 5 and the chamfering drill bit 6.

[0019] Reference Figure 1-3 , wherein the clamping assembly 7 includes an electric push rod 71, two electric push rods 71 ​​are fixedly installed on both sides of the fixing seat 2, and the two electric push rods 71 ​​are symmetrically arranged, the table top of the processing table 1 is provided with a slide rail 72, and a slider 73 is fixedly installed at the telescopic end of the electric push rod 71, and the slider 73 is slidably connected to the slide rail 72, and a clamping block 74 is arranged on the surface of the slider 73 away from the electric push rod 71;

[0020] Through the above-mentioned structural setting, the two electric push rods 71 ​​are started at the same time, and their telescopic ends extend outward, pushing the slider 73 to move toward the center position on the slide rail 72. As the slider 73 moves, the clamping block 74 also moves closer until the semicircular hole on the clamping block 74 fits tightly with the outer diameter of the sleeve, thereby fixing the sleeve to prevent it from shifting or falling off due to rotation or vibration, thereby ensuring the accuracy and quality of the chamfering process. After the processing is completed, the electric push rod retracts, the slider and the clamping block return to their original positions, and the sleeve is released, allowing it to slide smoothly to the lower hopper for collection.

[0021] Reference Figure 1-3 , wherein a semicircular hole matching the outer diameter of the sleeve is provided on the surface of the clamping block 74 on one side close to the feeding channel 3;

[0022] Through the above-mentioned structural arrangement, the clamping block 74 can fit tightly against the outer surface of the sleeve, and the size of the semicircular hole is adapted to the outer diameter of the sleeve, thereby ensuring the stability and accuracy of the clamping.

[0023] Reference Figure 1-3 , wherein a notch 9 communicating with the feeding channel 3 is provided on the fixed seat 2, and the notch 9 is adapted to the clamping block 74, and a chip removal groove 10 communicating with the feeding channel 3 is provided on the fixed seat 2;

[0024] Through the above-mentioned structural setting, when the sleeve enters the processing area through the feeding channel 3, the notch 9 allows the sleeve to slide smoothly into the clamping range of the clamping block 74, and ensures that the clamping block 74 can accurately and stably clamp the sleeve to prevent it from shifting or falling off during the processing. During the chamfering process, waste materials such as metal chips will be generated and may accumulate in the processing area, affecting the processing quality and equipment performance. The function of the chip removal groove 10 is to discharge these waste materials in time to keep the processing area clean and smooth.

[0025] Reference Figure 1-3 , wherein the limiting assembly 8 includes a connecting arm 81, the connecting arm 81 is fixedly mounted on the moving end of the lifting platform 4, the table top of the processing table 1 is fixedly mounted with a hinge seat 82, a connecting rod 83 is hinged on the hinge seat 82, one end of the connecting rod 83 is hinged to the connecting arm 81, and a plug 84 is fixedly mounted on the other end, and the plug 84 is located at the unloading end of the loading channel 3;

[0026] Through the above-mentioned structural arrangement, when the lifting platform 4 descends, that is, in preparation for chamfering processing, the connecting arm 81 descends, and through the transmission of the connecting rod 83, the plug 84 leaves the unloading end of the loading channel 3, thereby lowering the last processed sleeve to the finished product collection box 12. When the chamfering processing is completed, the lifting platform 4 rises, and the connecting arm 81 also rises accordingly, so that the plug 84 is reset to the unloading end of the loading channel 3, and the currently processed sleeve is limited, so that the next sleeve to be processed can be fixed in the processing position.

[0027] Reference Figure 1-3 , wherein a lower hopper 11 is provided on the processing table 1, and a finished product collection box 12 located at the discharge end of the lower hopper 11 is provided on one side of the processing table 1;
