[0001] The utility model relates to the technical field of Swiss-type lathes, in particular to a waste material discharging mechanism of Swiss-type lathes. Background Art

[0002] Swiss-type CNC lathe - the full name is Swiss-type CNC lathe, which is a precision processing equipment that can complete complex processing such as turning, milling, drilling, boring, tapping and engraving at the same time. It is mainly used for batch processing of precision hardware and special-shaped non-standard shaft parts.

[0003] A Swiss-type lathe generates a large amount of waste and debris during operation, which need to be discharged by a waste discharge mechanism. A Chinese utility model patent with the prior art publication number CN217045636U proposes a Swiss-type lathe with a chip collecting device, which can automatically clean the chips attached to the inner wall of the Swiss-type lathe body and collect the chips.

[0004] However, in the above-mentioned prior art, after collecting the waste chips on the top of the Swiss-type lathe, they only fall into the chip collecting trough through the chip collecting funnel. In the chip collecting trough, the waste materials and chips are mixed with a large amount of coolant, which is not separated and recycled.

When enough waste chips are accumulated in the receiving chamber, the push cylinder drives the piston rod to extend, pushing the push plate 1 to move along the receiving chamber of the casing toward the roller, so that the push plate 1 pushes the waste chips into the roller for compaction, so that part of the coolant on the waste chips is squeezed out, and the squeezed coolant flows into the bottom of the dehydration chamber of the casing through the micropores of the roller, so that the roller rotates, and the roller drives the compacted waste chips and the push plate 1 to rotate together, so that The remaining coolant in the waste chips is thrown out, and the thrown-out coolant flows into the bottom of the dehydration chamber of the casing through the micropores of the drum. The dehydrated and separated coolant is discharged into the coolant recovery barrel through the drain pipe. After the compaction and dehydration of the waste chips are completed, the piston rod of the push cylinder contracts, causing the push plate to return to the receiving chamber of the casing and reach the right side of the discharge port, and the compacted waste chips in the drum are discharged through the discharge port of the casing, thereby realizing the separation and recovery of coolant and waste chips, and compacting the waste and waste chips, which is convenient for transportation and packaging of waste and waste chips, and has good practicality.

A large number of micropores are arranged on the outer wall of the drum 6. A pick-up and release port is arranged at one end of the drum 6 facing the material receiving chamber. The inner diameter of the pick-up and release port is the same as the inner diameter of the material receiving chamber of the casing 3 and is concentrically aligned. The fixed end of the push cylinder 7 is installed at the right end of the casing 3, and the piston rod of the push cylinder 7 extends into the chamber of the casing 3.

The right end of the threaded rod 12 is concentrically installed with a push plate 13. The outer wall of the push plate 13 is in sliding contact with the inner wall of the drum 6. When the threaded rod 12 rotates in the same direction as the drum 6, the threads of the threaded rod 12 and the threaded sleeve 11 cause the push plate 13 to move rightward. A driving mechanism is arranged at the lower part of the Swiss machine body 1.

[0025] The motor 15 drives the drive shaft 14 to rotate through the transmission assembly 16. When the threaded rod 12 and the drum 6 move relative to each other, the spline groove of the drive shaft 14 and the spline of the threaded rod 12 achieve stable transmission, and the threaded rod 12 rotates forward. Under the action of the threads of the threaded sleeve 11 and the threaded rod 12, the threaded rod 12 pulls the push plate 13 to the left end of the drum 6. When the push plate 13 reaches the left end of the drum 6, the threaded rod 12 continues to rotate and drives the drum 6 to rotate forward under the action of the one-way ratchet 10, thereby realizing centrifugal dehydration of the waste and waste chips in the drum 6; when the waste and waste chips need to be discharged, the push cylinder 7 contracts and pulls the push plate 1 8 to move to the right end of the casing 3, and the push plate 1 8 moves the sliding door 17 to the right through the baffle to open the discharge port of the casing 3, the threaded rod 12 reverses, the one-way ratchet 10 prevents the drum 6 from reversing, and the threaded action of the threaded sleeve 11 and the threaded rod 12 causes the threaded rod 12 to push the push plate 2 13 to the right end of the drum 6, so that the push plate 2 13 pushes the compacted waste and waste chips in the drum 6 to the discharge port of the receiving chamber of the casing 3, thereby realizing automatic discharge of the waste and waste chips. After the discharge is completed, the threaded rod 12 rotates forward to make the push plate 2 13 return to the left end of the drum 6.

Then the motor 15 drives the drive shaft 14 and the threaded rod 12 to rotate through the transmission assembly 16. When the push plate 13 reaches the left end of the roller 6, the threaded rod 12 continues to rotate to drive the roller 6 to rotate forward under the action of the one-way ratchet 10. The roller 6 drives the compacted waste chips and the push plate 18 to rotate together, so that the remaining coolant in the waste chips is thrown out, and the thrown coolant passes through the micropores of the roller 6.

Finally, the threaded rod 12 rotates forward to make the push plate 2 13 return to the left end of the drum 6.
