Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, and in particular to a numerically controlled machine tool for linked processing of workpieces. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system.

[0003] In the prior art, the movement of the spindle and the movement of the workbench both need to be driven by a lead screw. However, the lead screw will heat up when it rotates for a long time, causing it to expand due to the heat, which will affect the transmission quality, that is, the transmission accuracy and the processing quality of the product. At the same time, the lead screw is in a heated state for a long time and is prone to deformation, which affects its service life and has a high maintenance rate. At the same time, when processing workpieces, the existing linkage CNC machine tools require the cooperation of staff to manually replace the workpieces. During the replacement, the processing equipment inside the machine tool is in a stopped state. When the equipment is stopped as a whole, the processing time of the workpiece will be increased, which is not conducive to the continuous processing of the workpiece.

[0028] When in use, the workpiece is placed on the conveyor belt 10. The intermittent drive device 6 can intermittently drive the conveyor belt 10 to work. The conveyor belt 10 drives the workpiece to move intermittently, and continuously feeds the workpiece, thereby facilitating the machine tool to continuously process the workpiece, thereby improving the processing efficiency of the workpiece. When the conveyor belt 10 stops, the pressing device 7 presses the workpiece tightly, and then drives the processing mechanism 8 to move downward through the self-cooling lifting mechanism to process the workpiece.

[0029] Embodiment 2

[0030] See also Figure 3-5 As shown, in order to facilitate the installation of the self-cooling lifting mechanism, a hot water chamber 31 and a cold water chamber 32 are respectively opened on the left and right sides of the column 3, a working chamber 33 is opened in the middle of the front end of the column 3, a first equipment chamber 34 is opened at the top of the column 3, and a discharge port 35 is opened in the middle of the lower end of the column 3, and the conveyor belt 10 passes through the discharge port 35.

[0031] The lifting assembly 4 includes a first motor 41, a driving screw 42 and two guide rails 44. The first motor 41 is fixedly installed in the first equipment cavity 34. The output end of the first motor 41 is fixedly installed with a driving screw 42.

[0032] In order to avoid that the transmission quality is affected due to the heat generated by the driving screw 42, a screw hole 431 is opened in the middle of the driving block 43, and a hot and cold exchange channel 432 is opened inside the inner wall of the screw hole 431. The hot and cold exchange channel 432 is spirally wound around the outside of the screw hole 431. The coolant exchanges heat and cools the driving screw 42 through the hot and cold exchange channel 432, thereby extending the service life of the driving screw 42 and ensuring the processing accuracy and quality of the workpiece.

The cold water pipe 93 is fixedly connected to the water inlet channel 433. The water outlet channel 434 is fixedly connected with the hot water pipe 94. A second delivery pipe 95 is fixedly installed at the other end of the hot water pipe 94.

A serpentine pipe 98 is fixedly installed at the rear end of the column 3. One end of the third delivery pipe 97 away from the second water pump 96 passes through the column 3 and is fixedly connected to the serpentine pipe 98. A fourth delivery pipe 99 is fixedly installed at the other end of the serpentine pipe 98. One end of the fourth delivery pipe 99 away from the serpentine pipe 98 passes through and extends into the cold water chamber 32. A heat sink 910 is fixedly installed on the outer surface of the serpentine pipe 98.

[0033] During operation, the coolant in the cold water chamber 32 is transported to the cold water pipe 93 through the cooperation of the first water pump 91 and the first delivery pipe 92, and then enters the cold and hot exchange channel 432 through the water inlet channel 433, absorbs the heat emitted by the driving screw 42 after spirally circling around in the cold and hot exchange channel 432, enters the hot water pipe 94 through the water outlet channel 434 after cold and hot exchange, and finally is transported to the hot water chamber 31 through the second delivery pipe 95, and then the second water pump 96 transports the coolant that has absorbed the heat in the hot water chamber 31 to the serpentine tube 98 through the third delivery pipe 97, and the coolant in the serpentine tube 98 is dissipated and cooled through the heat sink 910 outside the serpentine tube 98. After cooling, the coolant returns to the cold water chamber 32, and the coolant circulates back and forth, continuously absorbing the heat dissipated by the driving screw 42, cools the driving screw 42, extends the service life of the driving screw 42, and at the same time ensures the processing accuracy and quality of the workpiece.

[0034] Embodiment 3

[0035] See also Figure 7As shown, the intermittent drive device 6 includes an equipment box 61 and a third motor. A first drive rod 62 and a second drive rod 64 are connected to the equipment box 61 in rotation from front to back. A fan gear 63 is fixedly installed on the outer surface of the first drive rod 62. A ratchet 66 and a drive gear 65 are fixedly installed on the outer surface of the second drive rod 64 from left to right. The fan gear 63 is meshed with the drive gear 65.

While the second driving rod 64 rotates, it drives the ratchet 66 to rotate, and the ratchet teeth of the ratchet 66 press the pawl 67 downward, which will not affect the rotation of the second driving rod 64. When the fan gear 63 is away from the driving gear 65, the driving gear 65 stops rotating, and then the pawl 67 is squeezed upward by the spring 68 at the bottom, so that the pawl 67 is stuck inside the ratchet teeth, thereby preventing the ratchet 66 from rotating in the opposite direction. At the same time, the fan gear 63 is convenient for the repeated intermittent rotation of the driving gear 65, so that the workpiece on the top of the conveyor belt 10 is moved intermittently, and continuous loading is performed, thereby improving the processing efficiency.
