[0002] CNC lathes automatically process the parts to be processed according to a pre-compiled processing program. We compile the parts processing process route, process parameters, tool motion trajectory, displacement and cutting parameters and auxiliary functions into a processing program sheet according to the instruction code and program format specified by the CNC machine tool. We then record the contents of this program sheet on the control medium and then input it into the CNC device of the CNC machine tool to command the machine tool to process parts.

[0003] At present, CNC lathes are widely used. However, there are still some shortcomings in CNC lathes for camshaft processing. Some CNC lathes are used for cooling. For example, the coolant is usually discharged directly after cooling, which causes waste. It is not convenient to use the cycle cooling and it is not convenient to clean the waste residue. Therefore, a CNC lathe for camshaft processing with internal cycle cooling function is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 In this embodiment, a rapid cooling device for lathe processing includes a lathe 1, a fixing mechanism 2 is provided on the inner wall of the lathe 1, and a processing part 3 is provided on the lathe 1;

[0023] The workpiece 3 includes a liquid guide tank 31 having one end fixedly connected to the upper end of the lathe 1, a liquid storage tank 35 fixedly connected to the lower end of the lathe 1, a pump body 36 fixedly installed on one side of the liquid storage tank 35, a heat sink 38 fixedly installed on the inner bottom wall of the liquid storage tank 35, a support frame 39 fixedly connected to the lower end of the liquid storage tank 35, a fan 310 fixedly installed on one side of the support frame 39, a filter plate 37 having one end penetrating and extending to the inner side of the liquid storage tank 35 is slidably connected to the front side of the liquid storage tank 35, and a pump body 36 fixedly installed on one side of the liquid storage tank 35. A servo motor 34, the output shaft of the servo motor 34 is fixedly connected to a screw rod 33, the outer side of the screw rod 33 is threadedly connected to a driving block 311, a hydraulic rod 313 is fixedly installed on the inner side of the driving block 311, the output end of the hydraulic rod 313 is fixedly connected to a connecting plate 312, the lower end of the connecting plate 312 is fixedly connected to a rotating motor 314, the output shaft of the rotating motor 314 is fixedly connected to a tool 315, and one side of the liquid guide tank 31 is connected to a drain pipe 32 having one end penetrating and extending to the inner side of the lathe 1;

[0024] The liquid discharge pipe 32 is a hose, and a liquid guide hole is provided on the inner bottom wall of the lathe 1 .

[0025] In this embodiment, when the hydraulic rod 313 is started to drive the connecting plate 311 to move downward through the tool 315 to hit the workpiece, the pump body 36 can be started to transport the coolant in the liquid storage tank 35 to the liquid guide tank 31 and discharge it through the drain pipe 32 to flush and cool the tool, and at the same time, the debris can be washed away. When it flows back to the liquid storage tank 35 through the liquid guide hole on the bottom wall of the lathe 1, it can be filtered by the filter plate 37 and cooled by heat conduction by the heat sink 38, so that the coolant can be recycled, which saves resources and improves the cooling effect.

[0026] Among them, the number of heat sinks 38 is several, and several heat sinks 38 are equidistantly distributed on the inner bottom wall of the liquid storage tank 35. The end of the heat sink 38 located on the inner side of the liquid storage tank 35 is the heat absorption end. The coolant flowing back into the liquid storage tank 35 can be cooled by heat conduction through the several heat sinks 38, so as to improve the cooling effect of the coolant when it is cooled next time.

[0027] In addition, the liquid inlet end of the pump body 36 is connected to the liquid storage tank 35 through a pipe, and the liquid outlet end of the pump body 36 is connected to the liquid guide tank 31 through a pipe, so that the driven pump body 36 can transport the liquid from the liquid storage tank 35 to the liquid guide tank 31.

[0028] Secondly, a through hole is opened on the front of the liquid storage bin 35 and is located outside the filter plate 37 . A sealing ring with one end in contact with the through hole is fixedly connected to the outside of the filter plate 37 . Adding the sealing ring can improve the sealing performance of the filter plate 37 when it is pushed into the liquid storage bin 35 .

[0029] Then, the cross-section of the driving block 311 is U-shaped, and a threaded hole located on the outside of the screw 33 is opened at the upper end of the driving block 311, and the threaded hole cooperates with the thread on the outside of the screw 33. The upper end of the driving block 311 is fixedly connected to a slider with one end extending to the inside of the lathe 1, and a sliding groove adapted to the slider is opened on the inner top wall of the lathe 1, so that the rotating screw 33 can drive the driving block 311 to move laterally.

[0030] It should be noted that the fixing mechanism 2 is a conventional fixing part in an existing lathe and is an existing conventional structure, so the specific structure and operating principle are not described in detail in the text and figures.

[0031] See also Figure 2-3 In this embodiment, a support member for supporting the drain pipe 32 is provided at the lower end of the connecting plate 312. The support member includes a ring 318 whose one end is fixedly connected to the lower end of the connecting plate 312 and is located on the outside of the rotating motor 314. A retaining ring 316 is slidably connected to the inner side of the ring 318. The inner wall of the retaining ring 316 is fixedly connected to the liquid outlet end of the drain pipe 32. A spring 317 is fixedly connected between the upper end of the retaining ring 316 and the inner side of the ring 318.

[0032] In this embodiment, the collar 318 and the retaining ring 316 located outside the rotating motor 314 and the tool 315 can block the tool 315 during cooling processing, reduce the possibility of splashing of coolant and debris, and thus improve the workpiece processing effect.

[0033] The working principle of the above embodiment is:

[0034] Since the started servo motor 34 can drive the driving block 311 to move horizontally and adjust through the screw 33, the started hydraulic rod 313 drives the connecting plate 311 to move downward through the tool 315 to hit the workpiece, the coolant in the liquid storage tank 35 can be transported to the liquid guide tank 31 through the drain pipe 32 by starting the pump body 36 to flush and cool the tool, and at the same time, the debris can be flushed. When it flows back to the liquid storage tank 35 through the liquid guide hole on the bottom wall of the lathe 1, it can be filtered by the filter plate 37 and cooled by heat conduction by the heat sink 38, so that the coolant can be recycled, saving resources and improving the cooling effect. The ring 318 and the retaining ring 316 located on the outside of the rotating motor 314 and the tool 315 can block the tool 315 during cooling processing, reduce the possibility of splashing of coolant and debris, and thus improve the workpiece processing effect.
