[0032] Specifically, in use, since it needs to interface with existing CNC lathes and shaft-type transmission lines, the entire mechanism must be fixed to the lathe to achieve the interface between the shaft-type transmission line and the CNC lathe. The stepped feeding assembly 1, horizontal feeding assembly 2, vertical feeding assembly 3, positioning and clamping assembly 4, and shaft guiding assembly 5 are independent of each other, each performing different functions. Because it automatically feeds the lathe, all five mechanisms are fixed to the CNC lathe with screws. The stepped feeding assembly 1 receives parts from the shaft-type transmission line and then sends the shaft to the horizontal feeding assembly 2. Since there is a possibility of parts returning from the conveyor line, the stepped feeding assembly 1 has a return detection function. The feeding assembly 2 conveys the shaft to the vertical feeding assembly 3; the vertical feeding assembly 3 conveys the shaft to the positioning and clamping assembly 4; the positioning and clamping assembly 4 positions the shaft (modifying the lathe spindle), clamps it (using the lathe spindle for clamping), and ejects the shaft to the shaft guide assembly 5; the shaft guide assembly 5 guides the shaft to fall onto the shaft conveyor line or into a box; the stepped feeding assembly 1 is fixed to the CNC lathe via the stepped feeding base plate 119, and then connects to the shaft transmission line via the first mechanism base plate 107; the stepped feeding assembly 1 is similar to a hopper; the shaft parts are automatically conveyed to the first mechanism base plate 107. 7. The part rolls onto the part limiting block 124 under gravity. When the sensor on the fixed baffle 205 in the horizontal feeding assembly 2 does not detect the part, the lifting cylinder 101 moves upward, thereby driving the movable block 108 to move upward, thus sending the shaft to the step above the limiting block 124. This continuous action continuously feeds the shaft from bottom to top. The first proximity switch 104 detects whether the shaft is returning. After detecting the return of the shaft part, the pen-shaped cylinder 105 moves, thus pushing the returned shaft into the return collection box 122. The workpiece stop 123 is fixed to the left baffle 125 by screws and the distance can be adjusted to realize the transmission. The system feeds shaft parts of varying lengths (adjustable from 60mm to 300mm). The remaining parts in the stepped feeding assembly 1 are auxiliary installation parts. During operation, the horizontal feeding assembly 2 is fixed to the CNC lathe via the assembly base plate 201 and then connects to the stepped feeding assembly 1 via the material channel plate 210. The shaft parts are fed onto the material channel plate 210 via the stepped feeding assembly 1 and then automatically roll down onto the shaft support block 203 by gravity. After the third proximity switch 216 detects the part, the horizontal feeding cylinder 204 actuates, driving the first push rod 219 to push the shaft part into the vertical feeding assembly 3. The second proximity switch 209 is used to detect the presence or absence of material.The movable baffle 207 is fixed to the feed channel plate 210 with screws and its distance can be adjusted to automatically convey shaft parts of different lengths. The remaining parts in the horizontal feeding assembly 2 are auxiliary installation parts. During operation, the vertical feeding assembly 3 is fixed to the lathe by the fixed seat 325. Then, through the stabilizing block 324 and the second push rod 302, the shaft parts are fed into the second push rod 302 by the horizontal feeding assembly 2. The stabilizing block 324 is fixed to the fixed seat 325 with screws and is used to transfer the shaft parts to the second push rod 302. The lathe sends a signal to the vertical feeding assembly 3 to move it up and down. The cylinder 311 moves the second push rod 302 downwards to the concentric position of the lathe spindle. Then, the cylinder 311 retracts, driving the proximity switch mounting block 305, thereby pushing the shaft part into the positioning and clamping assembly 4. The proximity switch mounting block 305 is fixed with screws by the second limit stop 308 and its length is adjustable. The fourth proximity switch 326 detects whether the shaft has been pushed into place, and its position is adjustable by the adjusting block 327, thereby realizing the automatic conveying of shaft parts of different lengths. The remaining parts in the vertical feeding assembly 3 are auxiliary mounting parts. During the operation of the positioning and clamping assembly 4, the lathe spindle... Shaft 405 and push rod 406 are integral parts of the lathe spindle. The mechanism is connected to the lathe spindle 405 via spindle nut 402. The shaft part is pushed into the three-jaw chuck 407 by the vertical feeding assembly 3, compressing the push rod 406. When the push rod 406 contacts the adjusting screw 403, the shaft extension length is fully positioned by a hard limit. Then, the lathe moves to clamp the shaft part through the three-jaw chuck 407. After machining, the push rod 406 is pushed out by the second spring 404, thus ejecting the shaft part. The adjusting screw 403 is then threaded onto the spindle nut 402. This can be adjusted according to the type of shaft part. Adjust the length and then fix it with adjusting nut 401. During operation, first confirm that there are no shaft parts on the lathe spindle, then connect the power and air supply to the equipment, adjust the total air pressure to 0.4-0.6MPa, and press the start button on the lathe. The mechanism will start running automatically. In the initial state, the lifting cylinder 101 is in the retracted state, the pen-shaped cylinder 105 is in the retracted state, the horizontal feeding cylinder 204 is in the retracted state, the up-down movement cylinder 311 is in the retracted state, and the slider cylinder 304 is in the extended state. When the automatic run button is pressed, the equipment will automatically complete the following actions:

[0033] Action 1: When the second proximity switch 209 does not detect the presence of a shaft, the lifting cylinder 101 moves upward, driving the movable block 108 to move upward, continuously feeding the material to the horizontal feeding assembly 2 until 209 detects a part. During the feeding process to the horizontal feeding assembly 2, the first proximity switch 104 detects whether there is a return of material. The pen-shaped cylinder 105 extends and pushes the returned part into the return collection box 122 to prevent the returned part from proceeding to the next process and to ensure the correct direction of the conveying shaft material.

[0034] Action 2: When both the moving mechanism power plate 309 and the third proximity switch 216 detect material, the horizontal feeding cylinder 204 extends to drive the first push rod 219 to move, and then pushes out a shaft part to the second push rod 302 of the vertical feeding assembly 3. Then the horizontal feeding cylinder 204 retracts and sends a signal to the vertical feeding assembly 3.

[0035] Action 3: After receiving the signal from the horizontal feeding component 2, the vertical feeding component 3 extends the vertical movement cylinder 311 to send the second push rod 302 to a position concentric with the three-jaw chuck 407. Then, the slider cylinder 304 retracts, driving the proximity switch mounting block 305 to send the shaft part into the three-jaw chuck 407. The shaft is clamped by the positioning clamping component 4. Then, the slider cylinder 304 extends and the vertical movement cylinder 311 retracts, so that the vertical feeding component 3 returns to its initial state, avoiding interference between the lathe movement and the vertical feeding component 3. Then, a signal is sent to the lathe.

[0036] Action 4: After receiving the signal, the lathe automatically completes the turning action of the shaft part. After the turning action is completed, the positioning and clamping assembly 4 is released, and then the shaft is ejected and guided to the shaft conveyor line or the receiving tray 512 through the shaft guide assembly 5.
