DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application discloses a gas-liquid spraying mechanism for a machine tool. Figure 1 The gas-liquid spray mechanism for machine tools includes a chuck 1 and a spray head assembly 2. The chuck 1 is used to install the spray head assembly 2 on a spindle motor of a machine tool or a Z-axis sheet metal of the machine tool.

[0034] In some embodiments, the gas-liquid spray mechanism for machine tools further includes a set screw (not shown in the figure), which is a screw without a T-shaped head, and the chuck 1 is installed on the machine tool spindle motor through the set screw. Since the machine tool spindle motor cannot be drilled, the use of the set screw can stably and conveniently fix the chuck 1.

[0035] In some embodiments, the gas-liquid spray mechanism for machine tools further includes a locking screw (not shown in the figure), and the chuck 1 is provided with a mounting hole 3, and the locking screw mounts the chuck 1 on the Z-axis sheet metal of the machine tool through the mounting hole 3. Therefore, the chuck 1 can be conveniently fixed to the Z-axis sheet metal of the machine tool. It should be noted that the locking screw will not interfere with the sliding and mounting of the spray head assembly 2 on the chuck 1.

[0036] The chuck 1 of the present application can be replaced on the machine tool spindle motor or Z-axis sheet metal at any time as needed, and is more flexible to use. Therefore, it overcomes the problem in the prior art that when the spray seat 22 is customized according to the diameter of the machine tool spindle motor, if the outer diameter of the machine tool spindle motor is different, all the spray seats 22 need to be replaced, thereby increasing costs.

[0037] A clamping groove 4 is provided on one side of the chuck 1 along the circumferential direction, and clamping strips 5 are formed on both sides of the width direction of the clamping groove 4, and the clamping strips 5 are in an "L"-shaped structure. An insertion port 6 is provided on one side of the clamping strip 5, and the insertion port 6 is used for inserting the nozzle assembly 2 into the clamping groove 4. In this embodiment, the insertion port 6 is provided on the outer clamping strip 5, so that the nozzle assembly 2 can be inserted more conveniently.

[0038] Reference Figure 2, both sides of the nozzle assembly 2 are provided with matching grooves 7; during installation, the nozzle assembly 2 is inserted into the clamping groove 4 along the insertion port 6, and slides along the circumferential direction of the clamping groove 4, and the clamping strip 5 enters the matching groove 7 and is mutually clamped with the nozzle assembly 2, that is, the nozzle assembly 2 and the chuck 1 are mutually clamped with the matching groove 7 through the clamping strip 5. It should be noted that the nozzle assembly 2 and the chuck 1 are fixed by their own friction force, and a certain amount of manpower is required to slide. Therefore, during work, when the staff slides the nozzle assembly 2 to the corresponding position, the nozzle assembly 2 will not be misplaced.

[0039] In some embodiments, the gas-liquid spray mechanism for machine tools also includes a fixing part 8, which is used to prevent the nozzle assembly 2 from sliding out of the insertion port 6. The fixing part 8 is detachably installed in the clamping groove 4 of the chuck 1 and is located at the insertion port 6. In this embodiment, the fixing part 8 is located at the midpoint of the length direction of the insertion port 6, so that the nozzle assemblies 2 on both sides can be better blocked. In some embodiments, the fixing part 8 is a limit screw, and the limit screw is screwed to the chuck 1. The limit screw can be easily installed or removed at any time, so when the nozzle assembly 2 is inserted, the limit screw can be screwed into the chuck 1. When the nozzle assembly 2 needs to be increased or decreased, the limit screw can be screwed out of the chuck 1.

[0040] Refer again Figure 1 In some embodiments, at least two groups of nozzle assemblies 2 are provided. When installed, the nozzle assemblies 2 are arranged in sequence along the circumferential direction of the clamping groove 4. The number of groups of nozzle assemblies 2 can be set according to actual needs in the work. When it is necessary to increase the nozzle assemblies 2, the corresponding number of nozzle assemblies 2 are pushed in along the direction of the clamping groove 4 and arranged in sequence. When it is necessary to reduce the nozzle assemblies 2, the corresponding number of nozzle assemblies 2 are pushed out from the insertion port 6 along the direction of the clamping groove 4, so that the number of nozzle assemblies 2 can be flexibly increased or decreased. It overcomes the problem of work efficiency caused by the need to replace the nozzle seat 22 or re-drill holes on the Z-axis sheet metal when changing the number of nozzle seats 22 or nozzle members 24 in the prior art.

[0041] Reference Figure 3 In some embodiments, the nozzle assembly 2 includes a cover body 21, a nozzle seat 22, a quick air joint 23 and a nozzle member 24. The matching groove 7 is provided on the cover body 21, and the nozzle seat 22 is connected to the chuck 1 through the cover body 21. The cover body 21, the quick air joint 23 and the nozzle member 24 are all installed on the nozzle seat 22. In this embodiment, the cover body 21 is fixed to the nozzle seat 22 by four bolts and is sealed and fixed by a sealant to ensure the sealing of the nozzle seat 22. At the same time, the matching groove 7 is provided on the cover body 21, and the nozzle seat 22 is connected to the chuck 1 through the nozzle cover seat, so that the installation of the nozzle seat 22 can be facilitated; the quick air joint 23 fixes the nozzle seat 22 by screwing, and the end of the quick air joint 23 away from the nozzle seat 22 is used to connect the air pipe or the coolant pipe, so that compressed air or coolant can be introduced as needed.

[0042] In some embodiments, the nozzle member 24 includes a nozzle seat 241 and a nozzle body 242, the nozzle seat 241 is mounted on the nozzle seat 22, and the nozzle body 242 is rotatably connected to the nozzle seat 241. In some embodiments, the nozzle seat 241 is screwed to the nozzle seat 22, and a sealant is applied between the nozzle seat 241 and the nozzle seat 22 to fix the nozzle seat 22, so that the nozzle seat 22 can be better sealed. In this embodiment, the nozzle body 242 needs to be rotated by manpower, and the gap between the nozzle body 242 and the nozzle seat 241 will not leak coolant.

[0043] The implementation principle of a gas-liquid spray mechanism for a machine tool in an embodiment of the present application is as follows: a chuck 1 is used to install a nozzle assembly 2, and the nozzle assembly 2 is used to transport and spray cutting fluid or compressed air; during installation, the chuck 1 is installed on the machine tool, and the nozzle assembly 2 is inserted into the clamping groove 4 from the insertion port 6, and the nozzle assembly 2 is moved along the direction of the clamping groove 4 to move the nozzle assembly 2 to the desired position, and the nozzle assembly 2 and the chuck 1 are fixed by friction; when working, when the nozzle assembly 2 needs to be moved due to interference between parts, it is only necessary to push the nozzle assembly 2 with force, and the nozzle assembly 2 can slide along the direction of the clamping groove 4 to move the nozzle assembly 2 to a suitable position. Therefore, the position of the nozzle assembly 2 can be quickly adjusted to improve work efficiency.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
