Description

Technical Field

[0002] When machining workpieces using CNC (Computer Numerical Control) machine tools, a significant amount of heat is generated between the tool head and the workpiece, necessitating the use of a spray of liquid to cool the tool head.

[0072] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0073] See Figure 1 An embodiment of the present application provides a liquid spraying device 100 , including a connecting mechanism 10 , a liquid guiding tube 20 , a liquid path switching mechanism 30 and a liquid spraying mechanism 40 .

[0074] Specifically, see Figure 1 、 Figure 2 and Figure 3 The connecting mechanism 10 is provided with an air guide channel 11 and is connected to the air guide channel 11 (see Figure 7) has an air inlet 12, a first air outlet 13 and a second air outlet 14, the air inlet 12 is used to connect to the air supply device 200. The connecting mechanism 10 is used to connect to an external device (not shown), such as a tool handle of a processing tool. After the connecting mechanism 10 is fixedly connected to the external device, the liquid spraying mechanism 40 can be made to correspond to the tool head of the processing tool, thereby keeping the liquid spraying position stable. The liquid guide tube 20 is provided in the connecting mechanism 10, and one end of the liquid guide tube 20 is used to connect to the liquid supply device 300. The liquid circuit switching mechanism 30, which is connected to the first air outlet 13, is provided in the connecting mechanism 10 and clamps the liquid guide tube 20, and is used to clamp the liquid guide tube 20 to disconnect the liquid supply when the air guide channel 11 is not conducting air, and to loosen the liquid guide tube 20 to supply liquid when the air guide channel 11 is conducting air. The liquid spraying mechanism 40 is connected to the other end of the liquid guide tube 20 and the second air outlet 14, and is used to synthesize gas and liquid for spraying outward.

[0075] The liquid spraying device 100 provided in the embodiment of the present application has a connecting mechanism 10 connected to the gas supply device 200 through the gas inlet 12, and the gas flows to the first gas outlet 13 and the second gas outlet 14 through the gas guide channel 11. The connecting mechanism 10 can be connected to an external device to stabilize the liquid spraying position. The liquid circuit switch mechanism 30 is connected to the first gas outlet 13 and clamps the liquid guide tube 20, which is used to clamp the liquid guide tube 20 to disconnect the liquid supply when the gas guide channel 11 is not guiding gas, and to loosen the liquid guide tube 20 to supply liquid when the gas guide channel 11 is guiding gas. In this way, whether the liquid circuit switch mechanism 30 is opened can be synchronously controlled by whether gas is supplied in the gas guide channel 11, so as to realize the synchronous supply of gas and liquid, so that the amount of liquid sprayed can be accurately controlled. The liquid spraying mechanism 40 can synthesize gas and liquid into gas-liquid to spray outward.

[0076] In some embodiments, see Figure 2 、 Figure 5 、 Figure 6 and Figure 7 The connection mechanism 10 includes a support member 15, a vertical adjustment assembly 16, and a horizontal adjustment assembly 17. The air guide channel 11 is opened in the support member 15. The support member 15 is used to connect to an external device. The vertical adjustment assembly 16 is slidably connected to the support member 15. The horizontal adjustment assembly 17 is connected to the vertical adjustment assembly 16. The spray mechanism 40 is connected to the end of the horizontal adjustment assembly 17 away from the vertical adjustment assembly 16. The support member 15 can be a plate-like structure. One end of the support member 15 can be fixedly connected to the external device by bolts or the like. When the position of the spray mechanism 40 needs to be adjusted, it can be adjusted by adjusting the vertical adjustment assembly 16 and the horizontal adjustment assembly 17.

[0077] In some embodiments, see Figure 5 and Figure 6The vertical adjustment component 16 includes a first sliding member 161, a limiting plate 162, a connecting pin 163 and a vertical adjustment member 164. The support member 15 is provided with a sliding hole 151. The first sliding member 161 and the limiting plate 162 are arranged on opposite sides of the support member 15 and are connected by a connecting pin 163. The connecting pin 163 is slidably arranged in the sliding hole 151. The limiting plate 162 is provided with a first protrusion 1621. The horizontal adjustment component 17 is connected to the first sliding member 161. The vertical adjustment member 164 is fixedly connected to the support member 15 and is arranged corresponding to the first protrusion 1621. The vertical adjustment member 164 pushes the first protrusion 1621 to move to adjust the position of the limiting plate 162 and the first sliding member 161 in the vertical direction, thereby adjusting the position of the horizontal adjustment component 17 and the spray mechanism 40 in the vertical direction.

[0078] The first sliding member 161 may be a plate-shaped structure and extend vertically below the support member 15. The vertical adjustment member 164 may be a micrometer or the like, which drives the first protrusion 1621 to move vertically, thereby driving the limit plate 162 and the first sliding member 161 to move vertically, thereby changing the vertical position of the horizontal adjustment assembly 17 and the liquid spraying mechanism 40.

[0079] In some embodiments, see Figure 5 and Figure 8 The horizontal adjustment assembly 17 includes a first connecting plate 171, a second connecting plate 172, a second sliding member 173 and a horizontal adjustment member 174. The first connecting plate 171 is connected to the first sliding member 161, the second connecting plate 172 is connected to the side of the first connecting plate 171 away from the first sliding member 161, the second sliding member 173 is slidably connected to the side of the second connecting plate 172 away from the first connecting plate 171 along the horizontal direction, the spray mechanism 40 is connected to the second sliding member 173, the horizontal adjustment member 174 is movably connected to the second connecting plate 172 and connected to the second sliding member 173, and the horizontal adjustment member 174 is used to adjust the position of the second sliding member 173 in the horizontal direction, thereby adjusting the position of the spray mechanism 40 in the horizontal plane.

[0080] The first connecting plate 171 may have an L-shaped cross-section, with one end connected to the first sliding member 161 and the other end connected to the second connecting plate 172. The second connecting plate 172 may be a plate-like structure. A dovetail groove 1723 may be provided on the side of the second connecting plate 172 facing away from the first connecting plate 171. A dovetail protrusion 1731 corresponding to the dovetail groove 1723 may be provided on the side of the second sliding member 173 facing the second connecting plate 172. The dovetail protrusion 1731 slides in the dovetail groove 1723 to limit the vertical position of the second sliding member 173 while the second sliding member 173 is slidably connected to the second connecting plate 172. The horizontal adjustment member 174 may be a micrometer, etc., and the horizontal position of the second sliding member 173 and the liquid spraying mechanism 40 can be adjusted by the horizontal adjustment member 174.

[0081] In some embodiments, see Figure 5 and Figure 8 The horizontal adjustment assembly 17 also includes two rotary adjustment members 175 movably connected to the first connecting plate 171. The second connecting plate 172 is rotatably connected to the first connecting plate 171. The second connecting plate 172 is provided with a second protrusion 1721. The two rotary adjustment members 175 are both movably connected to the first connecting plate 171 and symmetrically arranged on both sides of the second protrusion 1721. The two rotary adjustment members 175 are used to push the second protrusions 1721 to drive the second connecting plate 172 to rotate relative to the first connecting plate 171 in the horizontal plane, thereby driving the second sliding member 173 and the spray mechanism 40 to rotate in the horizontal plane. The second connecting plate 172 can be rotatably connected to the first connecting plate 171 via a pin. The rotary adjustment members 175 can be bolts, etc. The rotary adjustment members 175 can push the second protrusions 1721 to rotate the second connecting plate 172 about the pin, thereby causing the second connecting plate 172 and the spray mechanism 40 to rotate in the horizontal plane to adjust the position of the spray mechanism 40 in the horizontal plane.

[0082] In some embodiments, see Figure 5 and Figure 8The horizontal adjustment assembly 17 also includes a locking member 176. The second connecting plate 172 has an arcuate hole 1722. The locking member 176 is inserted into the arcuate hole 1722 and connected to the first connecting plate 171. The locking member 176 is used to lock the first connecting plate 171 and the second connecting plate 172. It is understood that the center of the arcuate hole 1722 is located on the axis of rotation of the second connecting plate 172. The locking member 176 can be a bolt, etc. When adjusting the angle of the second connecting plate 172, the locking member 176 is first loosened, and then the angle of the second connecting plate 172 is adjusted by rotating the adjustment member 175. After adjustment, the locking member 176 is tightened to lock the second connecting member 31 and the first connecting member 31. When adjusting the locking member 176, if the second sliding member 173 blocks the locking member 176, the second sliding member 173 can be moved away by the horizontal adjustment member 174 to clear the locking member 176, making it easier to adjust the locking member 176.

[0083] In some embodiments, see Figure 2 and Figure 3 The liquid circuit switch mechanism 30 includes a connecting member 31, a clamping member 32, an elastic member 33 and a driving member 34. The connecting member 31 is connected to the connecting mechanism 10, and the clamping member 32 is rotatably connected to the connecting member 31. The clamping member 32 includes a first end 321 and a second end 322 opposite to each other. The first end 321 abuts against the liquid catheter 20. The elastic member 33 is connected to the connecting member 31 and the second end 322. The elastic member 33 is used to pull the clamping member 32 to rotate so that the first end 321 presses the liquid catheter 20. The driving member 34 is connected to the connecting member 31 and is arranged toward the second end 322. The driving member 34 is connected to the connecting member 31 and is arranged toward the second end 322. The driving member 34 is connected to the second air outlet 14 through the air guide tube 50. Among them, the elastic member 33 is used to pull the first end 321 of the clamping member 32 to move when the air guiding channel 11 is not guiding air, so that the second end 322 clamps the liquid guiding tube 20 to disconnect the liquid supply. The driving member 34 is used to push the first end 321 of the clamping member 32 to move when the air guiding channel 11 is guiding air, so that the second end 322 loosens the liquid guiding tube 20 to supply liquid.

[0084] The connecting member 31 is fixedly connected to the connecting mechanism 10. The driving member 34 may be a cylinder and is fixedly connected to the connecting member 31. The clamping member 32 may be an L-shaped structure and is rotatably connected to the connecting member 31. The second end 322 of the clamping member 32 abuts the driving member 34 and is connected to one end of an elastic member 33. The elastic member 33 may be a spring, etc., and the other end of the elastic member 33 is connected to the connecting member 31. When the airway tube 50 is not supplying air, the elastic member 33 pulls the second end 322 of the clamping member 32 to move, thereby causing the first end 321 of the clamping member 32 to push against the liquid catheter 20, thereby cooperating with the connecting member 31 to clamp the liquid catheter 20, thereby achieving closure of the liquid catheter 20. At this time, the liquid catheter 20 is not supplying liquid. When the air duct 50 is supplying gas, the gas is simultaneously delivered to the liquid spraying mechanism 40 and introduced into the driving member 34. At this point, the driving member 34 pushes against the second end 322 of the clamping member 32, causing the first end 321 of the clamping member 32 to release the liquid duct 20, allowing the liquid duct 20 to supply liquid to the liquid spraying mechanism 40. It will be appreciated that the distance the driving member 34 moves the second end 322 of the clamping member 32 is consistent with the degree to which the clamping member 32 releases the liquid duct 20, and both are proportional to the gas pressure generated by the gas duct 50 outputting gas to the driving member 34. In this manner, the gas and liquid supply amounts can be controlled to increase or decrease synchronously, achieving precise control of the liquid spraying amount.

[0085] In some embodiments, see Figure 4 The liquid spraying mechanism 40 includes a support member 41, an air jet pipe 42, and a liquid spray pipe 43. The support member 41 is connected to the connecting mechanism 10. The air jet pipe 42 is disposed within the support member 41 and connected to the second gas outlet 14 via the air guide pipe 50. The end of the air jet pipe 42 remote from the air guide pipe 50 extends out of the support member 41. The liquid spray pipe 43 is disposed within the support member 41 and connected to the liquid guide pipe 20. The end of the liquid spray pipe 43 remote from the liquid guide pipe 20 is inserted into the air jet pipe 42 to combine gas and liquid for outward spraying. The support member 41 may be a plate-like structure. Both the air jet pipe 42 and the liquid spray pipe 43 may be made of metal to enhance their structural strength and improve the stability of their connection to the support member 41. It is understood that the radius of the air jet pipe 42 is greater than the radius of the liquid spray pipe 43 to facilitate insertion of the liquid spray pipe 43 into the air jet pipe 42. When the air jet pipe 42 sprays air outward and the liquid spray pipe 43 sprays liquid outward, the air jet pipe 42 can generate negative pressure, thereby spraying the liquid provided by the liquid spray pipe 43 outward, providing uniformity in spraying, which is beneficial to improving the uniformity of cooling the external equipment.

[0086] It can be understood that a cover plate 45 can also be provided on the carrier 41. The cover plate 45 can be connected to the carrier 41 to cooperate with the carrier 41 to clamp the air injection pipe 42 and the liquid spray pipe 43, thereby improving stability and protecting the air injection pipe 42 and the liquid spray pipe 43.

[0087] In some embodiments, see Figure 4 The liquid spraying mechanism 40 further includes a clamping member 44, which is disposed at an end of the carrier 41 away from the connecting mechanism 10 and corresponds to the liquid spraying pipe 43. The clamping member 44 is used to clamp the liquid spraying pipe 43 to position the liquid spraying pipe 43. The clamping member 44 can be a bolt or the like. Two clamping members 44 can be provided and symmetrically disposed on both sides of the liquid spraying pipe 43 to clamp the liquid spraying pipe 43 to position the liquid spraying pipe 43.

[0088] The working process of the liquid spraying device 100 provided in the embodiment of the present application is roughly as follows:

[0089] First, connect the support member 15 to the external device, connect the air guide tube 50 to the air supply device 200, and connect the liquid guide tube 20 to the liquid supply device 300. Then, adjust the vertical position of the first slider 161 using the vertical adjustment member 164. Then, adjust the angle of the second connecting plate 172 and the second slider 173 using the rotation adjustment member 175. Finally, adjust the horizontal position of the second slider 173 using the horizontal adjustment member 174. This completes the position adjustment of the liquid spray mechanism 40, aligning the liquid spray tube 43 and the air jet pipe 42 with the tool of the external device. After the positions are adjusted, air is supplied to the air guide tube 50 through the air supply device 200, and liquid is supplied to the liquid guide tube 20 through the liquid supply device 300.

[0090] Then, by controlling the gas flow rate in the airway tube 50, when the gas flow rate in the airway tube 50 is zero, the driving member 34 stops driving the clamping member 32, and the elastic member 33 pulls the second end 322 of the clamping member 32 to move, thereby causing the first end 321 of the clamping member 32 to push against the liquid guide tube 20, thereby cooperating with the connecting member 31 to clamp the liquid guide tube 20, thereby closing the liquid guide tube 20. At this time, the liquid guide tube 20 is not supplied with liquid. When the airway tube 50 is controlled to supply gas, the gas is simultaneously delivered to the liquid spraying mechanism 40 and enters the driving member 34. At this time, the driving member 34 pushes against the second end 322 of the clamping member 32, causing the first end 321 of the clamping member 32 to release the liquid guide tube 20, allowing the liquid guide tube 20 to supply liquid to the liquid spraying mechanism 40. It can be understood that the movement distance of the second end 322 of the clamping member 32 driven by the driving member 34 is consistent with the degree to which the clamping member 32 loosens the liquid guide tube 20, and is proportional to the air pressure generated by the gas guide tube 50 outputting gas to the driving member 34.
