Description

Technical Field

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

[0002] The dual-spindle core-type CNC lathe is a high-precision and high-efficiency machine tool. It has two spindles, the main spindle and the sub-spindle. The core-type means that the bar is fed through the hollow part of the spindle, and during the processing, the tool performs various cutting operations around the bar. In terms of its structure, the two spindles are usually parallel to each other. The main spindle is used for initial processing procedures, such as external cylindrical turning, drilling, etc. The role of the sub-spindle is to take over the workpiece after the main spindle completes part of the processing and process the other end, such as processing the back of the workpiece, so as to achieve multi-faceted processing in one clamping, greatly improving the processing accuracy and efficiency.

[0003] In the field of mechanical processing, dual-spindle core-moving CNC lathes play an extremely important role and are widely used in the processing and manufacturing of precision parts. However, in the existing dual-spindle core-moving CNC lathe processing process, there are some problems that need to be solved urgently.

[0004] First, when unloading the finished parts, since cooling water is usually used to cool the tools and parts during the processing, the debris generated by the processing will be soaked by the cooling water, and these wet debris will fall onto the unloading plate together with the parts. In addition, even without the influence of cooling water, the dry debris will be unloaded along with the parts. This unloading method will cause the parts to be contaminated by debris, which seriously affects the cleanliness of the parts. Additional cleaning processes are required to ensure the cleanliness of the parts, which undoubtedly increases the production cost and processing time and reduces production efficiency; moreover, most of the existing dual-spindle core-type CNC lathes lack effective automatic loading mechanisms. In actual production, manual loading operations are often required, which not only consumes a lot of manpower and time, but also makes it difficult to ensure the accuracy and consistency of loading. The labor intensity of the operators is high, and the efficiency of manual loading is low, which cannot meet the needs of large-scale and high-efficiency production, limiting the application of dual-spindle core-type CNC lathes in automated production lines.

[0017] Beneficial effects of the present invention:

[0018] 1. When the present invention is working, since cooling water is needed to cool the part tool, the part debris will fall into the unloading plate along with the parts, the driving motor is started, and the driving motor is used to drive the driving disc to rotate. The transmission disc is braked synchronously through the transmission of the belt, and the driving disc is larger than the transmission disc. A tensioning rod is provided, and the tensioning disc is installed in different tensioning holes through fixing bolts to control the tensioning degree of the belt and ensure that both the driving disc and the transmission disc rotate. When the transmission disc rotates, the fan shaft is driven to rotate, and the fan shaft drives the fan blades to rotate, and air is blown outward through the air outlet of the fan housing, and the dry debris is separated from the wet debris and parts by wind force. The wet debris may adhere to the unloading plate due to the cooling water, so that the dry debris enters the dry chip bin through the guidance of the dry chip baffle plate 1 and the dry chip baffle plate 2, and the parts and the wet chips fall into the vibrating dividing plate, and the driving disc drives the crankshaft to rotate. Rotation. As the right side of the vibrating dividing plate rotates on the inner wall of the lower bin shell, the left side of the vibrating dividing plate begins to vibrate through the rotational connection relationship between the crank and the rotating connecting shaft, and the wet chips and parts are shaken to the left side of the vibrating dividing plate. The clumped wet chips have a certain fluidity and flow out of the wet material trough into the wet chip bin. There is a water pump inside the wet chip bin to extract cooling water. A mechanism is specially set to separate the chips soaked in cooling water and the dried chips from the parts, thereby avoiding the contamination of the parts by the chips, reducing the subsequent parts cleaning process, and ensuring that the parts remain clean and tidy during unloading. The surface quality and processing accuracy of the parts are greatly improved, which helps to produce higher quality products and meet the industry's demand for higher part cleanliness. Not only can the chips be separated from the parts, but also the separation of dry chips and wet chips can be completed with the help of the same driving source, which is convenient for the classification and recycling of different types of chips. Wet chips can be processed centrally to recover and reuse the coolant in them, reducing coolant waste and environmental pollution; dry chips can be processed according to the recycling process of metal waste, which increases the recycling value of the waste and complies with the concept of sustainable resource utilization and environmentally friendly production.

[0019] 2. The design of the present invention avoids the problems of inconsistent timing and poor connection that may occur when wet chips and dry chips are driven by different drive sources in traditional devices, improves the overall efficiency and quality of chip separation, ensures that dry chips and wet chips will not be mixed, and optimizes the chip separation process. After filtering out the dry chips, it is not necessary to enter other mechanisms to filter the wet chips. The generated wet chips and dry chips are continuously classified and processed, avoiding processing interruptions and greatly improving the effective processing time of the machine tool.

[0020] 3. The present invention also provides an automatic unloading mechanism. The material rod is placed inside the inclined hopper. Due to gravity, the material rod enters the feeding trough from the unloading trough. The feeding cylinder is started, the feeding cylinder retracts the synchronization rod, and the feeding push plate pushes the material rod into the hollow groove. At the same time, the feeding push plate blocks the material rod from entering the feeding trough. Only after the feeding push plate is reset will the material rod enter the feeding trough. The setting of the automatic loading mechanism enables the dual-spindle core-moving CNC lathe to realize automatic continuous production without frequent manual intervention in the loading process, reducing the impact of human factors on the production process.

[0037] During operation, since cooling water is needed to cool the part tool, the part debris will fall into the blanking plate 402 along with the parts, and the driving motor 303 is started. The driving motor 303 is used to drive the driving disc 304 to rotate, and the transmission disc 305 is synchronously braked through the transmission of the belt 307. The driving disc 304 is larger than the transmission disc 305, and a tensioning rod 306 is provided. The tensioning disc 309 is installed in different tensioning holes 308 through fixing bolts 310 to control the tensioning degree of the belt 307, so as to ensure that the driving disc 304 and the transmission disc 305 are both rotated. When the transmission disc 305 rotates, the fan shaft 404 is driven to rotate, and the fan shaft 404 drives the fan blades 405 to rotate, and the air is blown out through the air outlet of the fan housing 403. The wind separates the dry debris from the wet chips and parts.

A water inlet 702 is opened on the top of the tool station body 701. A cooling pipe 703 is fixedly connected to the front of the tool station body 701.

[0043] When working, the material rod is first fed into the machine tool through the hollow slot 805 of the main shaft 8. The control system drives the tool table 7 to process the material rod according to the pre-written CNC program. The tool 707 can perform various actions. There are various tools 707 on the tool disk 704. The tool table 7 is equipped with a cylinder and a motor, which can control the extension and rotation of the tool disk 704. The rotation effect is to change the tool of the tool disk 704, and the extension effect is to change the position of the tool 707 to process the material rod. The telescopic cylinder 802 on the main shaft 8 is driven by hydraulic pressure to control the extension and retraction of the telescopic cylinder 802. The rotating cylinder 803 is driven by a motor. The rotation of the rotating cylinder 803 is controlled, so that the position of the material rod and the processing angle change. The thumb cylinder 804 is a three-claw finger cylinder driven by compressed air, so that the three clamps synchronously perform linear reciprocating motion, thereby realizing the grabbing, clamping and loosening of the material rod. When the spindle 1 8 completes the processing of the front end of the workpiece, the spindle 2 9 is basically the same as the spindle 1 8 in structure, except that there is no hollow groove 805. The spindle 2 9 will move to a suitable position and cooperate with the spindle 1 8 to transfer the workpiece from the spindle to the spindle 2 9. This process is usually achieved through the synchronous rotation and relative movement of the two spindles. Then the spindle 2 9 drives the workpiece to rotate, and the rotating tool disk 704 replaces the tool 707 to continue processing the other end of the workpiece, such as processing the steps and threads on the back. The processed parts fall from the spindle 2 9 into the unloading port 10 and enter the unloading mechanism 4 together with the waste chips. The cooling pump 11 can extract cooling water and spray it through the cooling pipe 703 to act on the surface of the parts and the tool to prevent their temperature from being too high.

[0044] The present invention provides a dual-spindle core-moving CNC lathe, and the working principle is as follows: during operation, since cooling water is needed to cool the part tool, the part debris will fall into the blanking plate 402 along with the part, and the driving motor 303 is started, and the driving motor 303 is used to drive the driving disk 304 to rotate, and the transmission disk 305 is synchronously braked through the transmission of the belt 307, and the driving disk 304 is larger than the transmission disk 305, and a tensioning rod 306 is provided, and the tensioning disk 309 is installed in different tensioning holes 308 through fixing bolts 310 to control the belt 307. The tension of the drive disc 304 and the transmission disc 305 is ensured to rotate. When the transmission disc 305 rotates, the fan shaft 404 is driven to rotate, and the fan shaft 404 drives the fan blades 405 to rotate, and the air is blown out through the air outlet of the fan housing 403. Due to the cooling water, some dry chips will adhere to the unloading plate 402 into a ball. Generally speaking, the density of dry chips is usually smaller than that of water, and the shape is irregular. Under the action of wind, the debris is more likely to be entrained by the air flow and blown up, while water and wet chips are more likely to gather together due to factors such as surface tension and their own viscosity, and under gravity. The dry chips are more likely to sink under the action of the wind, and the dry chips are separated from the wet chips and parts by wind force, so that the dry chips enter the dry chip bin through the guidance of the dry chip baffle 1 406 and the dry chip baffle 2 407, and the parts and wet chips fall into the vibrating material dividing plate 408. The driving disk 304 drives the crankshaft 413 to rotate. Since the right side of the vibrating material dividing plate 408 rotates on the inner wall of the lower bin shell 401, the left side of the vibrating material dividing plate 408 begins to shake through the rotation connection relationship between the crank 414 and the rotating connecting shaft 415, and the wet chips and parts are shaken to the left side of the vibrating material dividing plate 408. The clumped wet chips are It has a certain fluidity and flows out from the wet material trough 412 into the wet chips bin 410. There is a water pump inside the wet chips bin 410 to extract cooling water. An automatic loading mechanism 6 is also provided. The material rod is placed inside the inclined hopper 601. Due to gravity, the material rod enters the feeding trough 603 from the unloading trough 602. The feeding cylinder 607 is started. The feeding cylinder 607 retracts the synchronization rod 606.
