Description

Technical Field

[0001] The invention relates to the technical field of CNC lathes, in particular to a dual-spindle synchronous processing CNC lathe. Background Art

[0002] A dual-spindle synchronous machining CNC lathe is a lathe with two spindles. The movement of the two spindles is precisely controlled by the CNC system, enabling synchronous machining operations.

[0003] After searching the Chinese patent with the publication number CN115338687A, a dual-spindle synchronous processing CNC lathe is disclosed, which relates to the technical field of CNC lathes, including a bottom plate, and the top of the bottom plate is respectively slidably embedded with a first sliding mechanism, a second sliding mechanism and a third sliding mechanism. The invention starts the motor H, which will drive the gear C to rotate. Since the gear C is meshed with one of the gears B, and a group of gears B are meshed with each other, the gear C can simultaneously drive a group of gears B to rotate when rotating, thereby driving the turning tool to rotate. When the turning tool is rotating at high speed, the cutting task of the workpiece will be completed. When the workpiece needs to be cut obliquely, it only needs to start the motor I, which will drive the rectangular shell to rotate, so that a certain bevel angle can be formed, and then the cutting of the workpiece bevel angle can be completed, effectively solving the shortcomings of the above patents, while increasing the workpiece processing efficiency, it also ensures the uniformity of the workpiece hole position.

[0004] However, the above invention has the following disadvantages:

[0005] Although the above technology can increase the workpiece processing efficiency while ensuring the uniformity of the workpiece hole position, when processing the workpiece, clean water is generally used to flush the waste chips. Clean water can flush most of the waste chips from the workpiece, but some waste chips will still remain on the workpiece. This causes the workpiece to be stored together with the waste chips when it is unloaded and stored, and the workpiece, waste chips and waste water cannot be completely separated. It needs to be processed again later, which is more troublesome. Summary of the invention

[0018] The present invention provides a dual-spindle synchronous processing CNC lathe through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the present invention sets a screening mechanism. When the workpiece and the wastewater with waste chips fall into the receiving box and the unloading box, the flip plate will first screen the workpiece and the wastewater. The workpiece will remain on the receiving plate and the flip plate, while the wastewater will flow to the inside of the filter seat and then be filtered by the filter screen. The waste chips will remain on the surface of the filter screen, and the wastewater will flow to the inside of the distribution box and then be discharged from the inside of the distribution box through the drain pipe, which is convenient for screening the workpiece and the wastewater.

[0020] Secondly, the present invention sets a transmission mechanism. After the receiving plate screens the workpiece and the wastewater, the workpiece will stay on the top of the receiving plate, and the receiving plate will be located below the inside of the discharge box. At this time, the second motor is started, and the second motor drives the transmission shaft to rotate. The transmission shaft drives the extrusion rod to rotate. The rotation of the extrusion rod will squeeze the bottom of the transmission block, thereby causing the transmission block to drive the receiving plate and the flip plate to move upward, and the receiving plate drives the workpiece to move upward. When the workpiece moves to the rectangular opening position opened on the discharge box, the workpiece will move to the inside of the storage box through the rectangular opening, and then the workpiece can be automatically collected. At the same time, the rotation of the extrusion rod can squeeze the first mounting rod. After the first mounting rod is squeezed, it will drive the cleaning brush to move inside the filter seat. When the cleaning brush moves on the filter screen, it will clean and push the waste on the filter screen. At this time, the waste on the filter screen will be pushed to the inside of the collection box and then collected, thereby achieving the effect of automatically screening the workpiece and the waste, and automatically classifying, collecting and storing the workpiece and the waste.

[0021] Third: In the present invention, through the setting of the L-shaped block, when the receiving plate and the flip plate move downward, the inclined surface of the L-shaped block will be squeezed, and the L-shaped block will then move toward the outside of the discharge box. At this time, the flip plate will not flip; when the receiving plate and the flip plate move upward, the flip plate will contact the bottom wall of the L-shaped block. At this time, the flip plate will be forced to flip, and the waste chips remaining on the flip plate can fall down to the inside of the filter seat, thereby improving the collection effect of the waste chips.

[0022] Fourthly, the present invention arranges a linkage mechanism. When the workpiece is processed, the second telescopic rod can drive the workpiece to move downward, thereby causing the driving motor seat to drive the first rack to move downward, and the first rack is meshed with the transmission gear, and the transmission gear will be driven to rotate. At the same time, the transmission gear is meshed with the second rack. The rotation of the transmission gear will cause the second rack to drive the material receiving box to move upward. When the workpiece approaches the material receiving box, the fixed claw plate can release the workpiece, so that the workpiece falls into the inside of the material receiving box, thereby achieving the operation of the material receiving box moving upward to receive the workpiece while the workpiece moves downward, reducing the impact caused by falling on the material receiving box, and protecting the workpiece and the material receiving box.

The waste chips will remain on the surface of the filter screen 23, and the wastewater will flow into the interior of the distribution box 12, and then can be discharged from the interior of the distribution box 12 through the drain pipe 39;

When the workpiece moves to the rectangular opening position opened on the discharge box 11, the workpiece The workpieces will move through the rectangular opening into the storage box 14, and then the workpieces can be automatically collected. At the same time, the rotation of the extrusion rod 20 can squeeze the first mounting rod 25. After the first mounting rod 25 is squeezed, it will drive the cleaning brush 24 to move inside the filter seat 22. The cleaning brush 24 moves on the filter screen 23 to clean and push the waste chips on the filter screen 23. At this time, the waste chips on the filter screen 23 will be pushed into the collection box 21 and then collected. Thereby, the workpieces and waste chips can be automatically screened, and the workpieces and waste chips can be automatically classified, collected and stored.
