[0029] Please see Figures 1-8 As shown, the purpose of this embodiment is to provide an automatic material receiving mechanism for a lathe, including a housing 1, a machining cavity 11 inside the housing 1, a spindle 2 fixedly mounted on the side wall of the machining cavity 11, a plurality of clamping grooves 24 arranged in a ring array on the side wall of the spindle 2, chucks 25 slidably mounted in the clamping grooves 24, and parts 23 clamped between the chucks 25, a shrinkage groove a21 is provided at the center of the side wall of the spindle 2, and a mounting block 22 is slidably mounted in the shrinkage groove a21. The mechanism also includes a receiving frame 3, a rotating groove a12 is provided on the lower surface of the machining cavity 11, the receiving frame 3 is rotatably mounted in the rotating groove a12, and chucks 13 are symmetrically provided on both sides of the rotating groove a12, and the chucks 13 hold... A bracket 33 is installed, and a receiving groove 311 is opened in the receiving frame 3. A telescopic frame 31 is rotatably installed in the receiving groove 311. The telescopic frame 31 receives the processed part 23. The claw 25 is used to fix the part 23. The mounting block 22 is used to push the part 23. The connecting block 321 is rotated to bring one end of the receiving frame 3 close to the part 23. When receiving material, the telescopic frame 31 is rotated to bring it close to the part 23. The spring c341 pushes the telescopic frame 31 to rotate, so that one end of the telescopic frame 31 extends out of the receiving groove 311, so that the telescopic frame 31 is located directly below the part 23 and the telescopic frame 31 is horizontal. The horizontal telescopic frame 31 is close to the part 23 to prevent the part 23 from being damaged when receiving material.

[0030] The receiving frame 3 has an installation groove 34 on its lower surface. A spring c341 is fixedly installed at the bottom of the installation groove 34. The other end of the spring c341 is fixedly installed on the lower surface of the telescopic frame 31. A pressure block 315 is rotatably installed on the upper surface of the receiving frame 3 near one edge. When the pressure block 315 is rotated, the spring c341 pushes the telescopic frame 31 closer to the part 23 to prevent the part 23 from being damaged when receiving materials.

[0031] A mounting plate 313 is rotatably mounted on one side of the telescopic frame 31. One end of the mounting plate 313 has an angled opening that slopes from the telescopic frame 31 towards the bracket 33. A positioning screw hole 314 is provided through the side wall of the mounting plate 313, and a fixing screw hole 312 is provided on the side wall of the telescopic frame 31. When the mounting plate 313 is rotated to vertical, the positioning screw hole 314 and the fixing screw hole 312 are horizontally aligned. A fixing bolt is installed in the internal thread of the positioning screw hole 314. When receiving material, the mounting plate 313 is rotated to vertical, and the fixing bolt in the positioning screw hole 314 is tightened and threaded into the fixing screw hole 312 to fix the position of the mounting plate 313 and prevent the part 23 from falling off when receiving material. After receiving material, the telescopic frame 31 is pressed into the receiving frame 3, the pressure block 315 is rotated to fix the position of the telescopic frame 31, and the mounting plate 313 is rotated to allow the part 23 to slide along the receiving frame 3 into the bracket 33.

[0032] The main shaft 2 has a shrinkage groove b26 on its side wall that connects to the shrinkage groove a21. A limit block a261 is slidably installed in the shrinkage groove b26. A limit block b262 is fixedly installed on the side wall of the limit block a261. A spring b263 is fixedly installed on the side wall of the limit block b262. The other end of the spring b263 is fixedly installed in the shrinkage groove b26. One end of the limit block a261 is an inclined structure that fits tightly with the limit groove 221. The limit block a261 is used to limit the position of the mounting block 22. After the material is received, the spring b263 pushes the limit block a261. The limit block a261 squeezes the angled corner in the limit groove 221 at the angled corner to push the mounting block 22 to slide inward into the shrinkage groove a21.

[0033] A lead screw 241 is rotatably installed in the clamping groove 24, and a lead screw nut 251 is slidably installed in the clamping groove 24. The lead screw nut 251 is threadedly engaged with the lead screw 241, and the lead screw nut 251 is a T-shaped structure adapted to the clamping groove 24. A chuck 25 is fixedly installed at one end of the lead screw nut 251. Rotating the lead screw 241 controls the sliding of the chuck 25 to control the clamping force of the chuck 25 on the part 23. When it is necessary to receive the part 23 after clamping, rotating the lead screw 241 causes the chuck 25 to move outward so that the part 23 can enter the receiving frame 3.

[0034] A spring a211 is fixedly installed at the bottom of the shrinkage groove a21, and the other end of the spring a211 is fixedly installed on one side of the mounting block 22. A limiting groove 221 is opened on the side wall of the mounting block 22. The limiting groove 221 is inclined from the inside of the shrinkage groove a21 to the outside of the shrinkage groove a21. When one end of the limiting block a261 is engaged in the limiting groove 221, the spring a211 is in a compressed state. When it is necessary to receive the finished part 23, the spring a211 pushes the mounting block 22 and pushes the part 23 into the telescopic frame 31.

[0035] A rotating groove b121 is provided on one side of the rotating groove a12. A shaft hole communicating with the rotating groove a12 is provided on the side wall of the rotating groove b121. A connecting shaft 32 is fixedly installed on the side wall of the receiving frame 3. The connecting shaft 32 is rotatably installed in the shaft hole. A connecting block 321 is fixedly installed on one end of the connecting shaft 32. The connecting block 321 is rotatably installed in the rotating groove b121. Rotating the connecting block 321 drives the receiving frame 3 to rotate. When the part 23 needs to be received after processing, the connecting block 321 is rotated so that one end of the receiving frame 3 is close to the part 23. After the part 23 falls into the receiving frame 3, the part 23 enters the bracket 33 along the receiving frame 3 for storage.

[0036] A locking block 331 is fixedly installed at one end of the bracket 33. The locking block 331 is snapped into the slot 13. The bracket 33 slides along the slot 13 via the locking block 331. The bracket 33 is used to store the processed parts 23. When the stored parts 23 are full, the bracket 33 is slid out of the slot 13 to replace the bracket 33.

[0037] In practical use, when the lathe needs to automatically receive materials, the connecting block 321 is rotated to drive the receiving frame 3 to rotate, so that one end of the receiving frame 3 is close to the part 23. The pressure block 315 is rotated, and the spring c341 pushes the telescopic frame 31 to rotate, so that the telescopic frame 31 is close to the part 23. The mounting plate 313 is rotated to be vertical, and the fixing bolt in the positioning screw hole 314 is tightened to install the thread into the fixing screw hole 312 to fix the position of the mounting plate 313. The screw 241 is rotated to make the pawl 25 slide outward, pulling the limiting block a261 outward. The spring a211 in the shrinkage groove a21 pushes the mounting block 22, and the mounting block 22 pushes the part 23, so that the part 23 enters the telescopic frame 31. The part 23 slides along the receiving frame 3 into the bracket 33. The bracket 33 is used to store the part 23. The bracket 33 is snapped into the slot 13. When the bracket 33 is full, it is taken out and replaced.
