[0050] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0051] See also Figure 1 The embodiment of the present application provides a processing device 200 including a processing spindle (not shown), a cooling mechanism 100 and a processing tool 201. For example, the processing spindle can be a machine spindle, and the processing tool 201 can be a milling cutter with a tool handle.

[0052] See also Figure 1 、 Figure 2 and Figure 3 The cooling mechanism 100 includes a fixing member 10 , a liquid inlet member 20 and a plurality of injection members 30 .

[0053] The fixing member 10 is coaxially connected to the machining spindle and is provided with a through hole 11 and an annular groove 12. The through hole 11 extends axially through the fixing member 10 on opposite sides of the fixing member 10. The fixing member 10 is also used to connect to the machining tool 201. The machining tool 201 passes through the through hole 11 to connect to the machining spindle. The annular groove 12 is arranged around the through hole 11. A liquid inlet 20 is arranged on the outside of the fixing member 10 and is connected to the annular groove 12 and an external liquid supply member (not shown). The liquid inlet 20 is used to introduce liquid provided by the external liquid supply member into the annular groove 12. A plurality of injection members 30 are arranged at intervals around the through hole 11 and are all movably connected to the fixing member 10 to adjust the angle relative to the machining tool 201. Each injection member 30 is connected to the annular groove 12 and is used to guide the liquid in the annular groove 12 to the machining tool 201. For example, the liquid can be a coolant, and the injection member 30 can be an injection portion with a universal joint, an injection head, or a similar injection body. Here, multiple refers to two or more.

[0054] When the above-mentioned cooling mechanism 100 and processing device 200 are in use, the angles of the multiple injection parts 30 relative to the processing tool 201 are adjusted according to the processing cooling requirements, so that the multiple injection parts 30 arranged at intervals around the through hole 11 evenly spray the liquid in the annular groove 12 to the circumference of the processing tool 201, thereby realizing multi-angle injection of liquid to the circumference of the processing tool 201, so that the liquid injected by the multiple injection parts 30 completely covers the processing tool 201, thereby achieving improved cooling efficiency at a low cost.

[0055] See also Figure 2 and Figure 3 In some embodiments, the injection member 30 is provided with an injection hole 31 , which is connected to the annular groove 12 , and the radial cross-sectional area of the injection hole 31 along the injection member 30 is smaller than the radial cross-sectional area of the annular groove 12 along the through hole 11 .

[0056] In this way, by setting the radial cross-sectional area of the injection hole 31 to be smaller than the radial cross-sectional area of the annular groove 12 along the through hole 11, in the process of the liquid being transported from the liquid inlet part 20 through the annular groove 12 to the injection hole 31, the cross-sectional area of the liquid flow channel becomes smaller, thereby increasing the fluid pressure of the liquid, so that the injection part 30 sprays high-pressure liquid to the processing tool 201, so that the high-pressure liquid can stably remove the debris adhered to the processing tool 201, so as to improve the cooling efficiency and thereby the processing quality of the processing tool 201.

[0057] See also Figure 2In some embodiments, the fixing member 10 includes a fixing body 13 and a locking body 14. The fixing body 13 is used to abut against the machining spindle and has a countersunk hole 131. The through hole 11 and the annular groove 12 are both provided in the fixing body 13. The fixing body 13 is respectively connected to the liquid inlet member 20 and the plurality of injection members 30. The locking body 14 is provided through the countersunk hole 131 and is used for detachable connection with the machining spindle. For example, the locking body 14 can be a screw.

[0058] In this way, the locking body 14 is inserted into the countersunk hole 131 and detachably connected to the processing spindle, so that the fixing member 10 and the processing spindle form a split structure, which is convenient for the operator to quickly disassemble and assemble the cooling mechanism 100 to the processing spindle.

[0059] See also Figure 2 In some embodiments, there are multiple countersunk holes 131, which are spaced apart around the through hole 11. There are multiple locking bodies 14, each corresponding to each of the multiple countersunk holes 131. In this way, the fixing body 13 is locked to the machining spindle by the multiple locking bodies 14, thereby improving the fixed installation position of the fixing body 13 and enhancing the installation stability of the fixing member 10.

[0060] Please continue reading Figure 2 In some embodiments, the fixed body 13 includes a fixed portion 132 and a connecting portion 133. One end of the fixed portion 132 is connected to the machining spindle, the outer side of the fixed portion 132 is connected to the liquid inlet member 20, the annular groove 12 is provided in the fixed portion 132, and the connecting portion 133 corresponds to the fixed portion 132 being away from the machining spindle. The outer side of the connecting portion 133 is connected to the plurality of injection members 30. The through hole 11 sequentially penetrates the fixed portion 132 and the connecting portion 133, and the cross-sectional area of the connecting portion 133 gradually decreases along the direction from the fixed portion 132 to the connecting portion 133.

[0061] In this way, by setting the cross-sectional area of the connecting portion 133 to gradually decrease in the direction from the fixing portion 132 to the connecting portion 133, the installation space occupied by the fixing member 10 is reduced, and interference between the fixing member 10 and other components is avoided, which is beneficial to the reasonable layout of the cooling mechanism 100.

[0062] See also Figure 2 In some embodiments, the fixing body 13 further includes an abutting portion 134 , which is arranged around the through hole 11 and on a side of the connecting portion 133 away from the fixing portion 132 , and is used to abut against the machining tool 201 .

[0063] In this way, since the processing tool 201 includes a tool handle and a tool, the abutment portion 134 is provided to abut the tool handle of the processing tool 201 to support the tool handle, so that the tool handle and the tool connected thereto remain in a stably installed state, thereby allowing the tool to perform processing operations stably.

[0064] See also Figure 2 In some embodiments, the fixed body 13 is provided with a plurality of avoidance grooves 135 , which are all opened on the outside of the fixed body 13 and are arranged one-to-one corresponding to the plurality of injection members 30 , and the avoidance grooves 135 accommodate the corresponding injection members 30 .

[0065] In this way, by setting a plurality of avoidance grooves 135 on the outside of the fixed body 13, the plurality of avoidance grooves 135 can respectively accommodate the corresponding injection parts 30, so that each injection part 30 has a sufficiently large movable space to adjust the injection angle, avoiding interference between the injection part 30 and the fixed body 13 during the angle adjustment process, which is beneficial to the injection angle adjustment of the injection part 30.

[0066] See also Figure 3 In some embodiments, the through hole 11 includes a positioning groove 111 and a mounting groove 112 that are connected to each other. The positioning groove 111 and the mounting groove 112 are coaxially arranged. The positioning groove 111 receives and positions the machining spindle, and the mounting groove 112 receives and positions the machining tool 201.

[0067] In this way, by setting the positioning groove 111 and the installation groove 112 coaxially, the machining spindle accommodated in the positioning groove 111 and the machining tool 201 accommodated in the installation groove 112 can be accurately matched, avoiding misaligned connection between the machining spindle and the machining tool 201, which is conducive to the accurate connection between the machining spindle and the machining tool 201.

[0068] See also Figure 2 In some embodiments, a chamfer 1111 is provided at one end of the positioning groove 111 away from the mounting groove 112 .

[0069] In this way, by setting a chamfer 1111 at the notch of the positioning groove 111, the chamfer 1111 avoids the processing spindle when the processing spindle is inserted into the positioning groove 111, thereby preventing the processing spindle from colliding with the fixing part 10 during the assembly process.

[0070] See also Figure 2 In some embodiments, the connecting portion 133 is provided with a plurality of anti-slip grooves 1331 , and the plurality of anti-slip grooves 1331 and the plurality of injection members 30 are alternately arranged on the outer side of the connecting portion 133 along the circumference of the connecting portion 133 .

[0071] In this way, by providing multiple anti-slip grooves 1331 , the friction between the operator and the fixing member 10 can be increased during the assembly process of the machining spindle and the fixing member 10 , making it easier for the operator to assemble the fixing member 10 to the machining spindle.

[0072] The working process of the above-mentioned processing device 200 is roughly as follows:

[0073] First, the machining spindle and the machining tool 201 are inserted into the positioning groove 111 and the mounting groove 112 respectively, so that the machining tool 201 is connected to the machining spindle. The locking body 14 is inserted into the countersunk hole 131 and connected to the machining spindle, so that the machining spindle is connected to the machining tool 201 through the fixing member 10.

[0074] Then, the angles of the plurality of injection members 30 relative to the machining tool 201 are adjusted according to machining cooling requirements;

[0075] Finally, multiple injection members 30 spaced apart around the through hole 11 evenly spray the liquid in the annular groove 12 to the circumference of the machining tool 201, thereby achieving multi-angle spraying of liquid to the circumference of the machining tool 201, so that the liquid sprayed by the multiple injection members 30 completely covers the machining tool 201, thereby improving the cooling efficiency at a low cost.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
