[0002] A lathe is a machine tool mainly used for turning and machining rotating workpieces with a turning tool. A lathe is the most important cutting machine tool among metal cutting machine tools. In general machine manufacturing factories, the number of lathes is the largest, and it is also called the mother machine. Drills, reamers, broaches, taps, dies, knurling tools, etc. can also be used for corresponding processing on the lathe. The function of a lathe is to perform cutting processing on various rotating surfaces and helical surfaces with different sizes and shapes.

The second motor 14 is fixed to the end of the fixing plate 12 away from the turntable 23. The output end of the second motor 14 is sleeved with a fourth bevel gear 24, and the side of the fourth bevel gear 24 is engaged with the fifth bevel gear 25. The bottom of the fifth bevel gear 25 is fixed with a second snap ring 26, and the second snap ring 26 is sleeved on the transmission shaft 7. A connecting plate 15 is provided on the side of the second motor 14. The second motor 14, the fourth bevel gear 24, the fifth bevel gear 25, the second snap ring 26, the fixing plate 12 and the first bevel gear 13 are mirror-imaged at both ends of the connecting plate 15. A second slider 17 is provided in the middle of the connecting plate 15. The nozzle 11 is fixed on the second slider 17. The up, down, left and right displacements of the nozzle 11 are controlled by the first motor 8 and the second motor 14, so as to move it to the processing area.

[0027] Furthermore, first clamping blocks 9 are fixed at both ends of the connecting rod 2, and each first clamping block 9 is inserted into an opening 30 opened at the end of the first threaded rod 3 to prevent the spacing between the first threaded rods 3 from changing.

[0028] Furthermore, a plurality of third slide grooves 22 are provided on the side of the transmission shaft 7, and a limit block 20 is provided in each third slide groove 22. The limit block 20 is fixed in a ring shape on the inner wall of the first retaining ring 21. The third slide grooves 22 cooperate with the limit block 20 to drive the transmission shaft 7 to rotate while ensuring that the transmission shaft 7 can move up and down.

[0029] Furthermore, a second clamping block 28 is sleeved on the outer side of the first clamping ring 21 . The second clamping block 28 is fixed on the connecting rod 2 . The second clamping block 28 is used to limit the position of the first clamping ring 21 .

[0030] Furthermore, a second sliding groove 16 is formed on the connecting plate 15 to assist the movement of the second sliding block 17 .

[0031] Further, one end of the nozzle 11 is connected to a delivery hose 5, and the end of the delivery hose 5 away from the nozzle 11 is connected to the processing table main body 112 for delivering coolant to the nozzle 11.

[0032] Further, the inner side wall of the second clamping ring 26 is provided with a thread matching the first threaded rod 3 for assisting the second clamping ring 26 to drive the connecting plate 15 to move up and down.

[0033] Further, a control screen 111 is provided on one side of the processing table main body 112 for controlling the start and stop of the first motor 8 and the second motor 14.

[0034] Working principle: When the lathe starts processing, first drive the nozzle 11 to the required position by moving the first threaded rod 3. Subsequently, control the start and stop of the first motor 8 and the second motor 14 through the control screen 111. When the first motor 8 is started, the first motor 8 drives the second bevel gear 18 to rotate, the second bevel gear 18 drives the third bevel gear 19 to rotate, and the third bevel gear 19 drives the first clamping ring 21 to rotate. Thus, the drive shaft 7 is pushed to rotate through a number of limiting blocks 20 and the third chute 22. The drive shaft 7 drives the sixth bevel gear 27 to rotate, and the sixth bevel gear 27 drives the first bevel gear 13 to rotate, thereby driving the second threaded rod 4 to rotate. The second threaded rod 4 pushes the second slider 17 to move left and right to drive the nozzle 11 to move, so as to control the left and right position of the nozzle 11 and spray coolant on the workpiece processing area.

[0035] By controlling the rotation of the second motor 14 to drive the fourth bevel gear 24 to rotate, the fourth bevel gear 24 pushes the fifth bevel gear 25 to rotate, and the fifth bevel gear 25 drives the second clamping ring 26 to rotate. Since the inner side wall of the second clamping ring 26 is provided with a thread and both ends of the connection are sleeved on the second clamping ring 26, when the second clamping ring 26 rotates, it drives the connecting plate 15 to move up and down along the first threaded rod 3. The connecting plate 15 drives the second slider 17 to move up and down, so as to control the up and down displacement of the nozzle 11. The fixing plate 12 and the turntable 23 ensure that when the connecting plate 15 moves up and down, the drive shaft 7 also moves accordingly. The third chute 22 provided on the side of the drive shaft 7 cooperates with the limiting blocks 20 to ensure that the first motor 8 can also push the drive shaft 7 to rotate through the second bevel gear 18 and the third bevel gear 19 when the drive shaft 7 moves up and down.

[0036] Control the start and stop of the first motor 8 and the second motor 14 through the control screen 111 to control the up, down, left and right displacement of the nozzle 11 until the nozzle 11 stays at the workpiece processing area.

[0037] It should be noted that: The entire device is controlled by a total control device. Since the devices matched with the control device are common devices and belong to the existing mature technology, the electrical connection relationship and the specific circuit structure are not described herein again.

[0038] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
