The above-mentioned separate cooling liquid pipe is prone to misalignment under the action of external force, and is inconvenient to use. CONTENT OF THE UTILITY MODEL

[0004] One of the technical problems to be solved by the present application is that the cooling liquid pipe is prone to misalignment and is inconvenient to use.

[0005] To solve the above technical problems, the present application provides a glass drilling cutter assembly, which comprises: a cutter connecting rod structure, the first end of the cutter connecting rod structure having a cooling liquid inlet, the side wall of the second end of the cutter connecting rod structure having a cooling liquid outlet, the cooling liquid inlet being in communication with the cooling liquid outlet; a cutter structure, the first end of the cutter structure being closedly connected to the outer wall of the cutter connecting rod structure, the second end of the cutter structure extending away from the first end of the cutter connecting rod structure, the cooling liquid outlet being located in the cutter structure, and the outer wall of the cutter connecting rod structure and the inner wall of the cutter structure having a predetermined distance.

[0006] In some embodiments, the cooling liquid outlet is inclined downward in the direction from the center axis of the cutter connecting rod structure to the outer wall of the cutter connecting rod structure.

[0008] In some embodiments, d is in the range of 3mm to 6mm, and L is in the range of 4mm to 16mm.

[0009] In some embodiments, in the direction from inside to outside, the cooling liquid outlet gradually increases along the circumference of the cutter connecting rod structure.

[0010] In some embodiments, there are multiple coolant outlets, which are arranged circumferentially along the tool link structure.

[0011] In some embodiments, the second end of the tool structure has multiple grooves.

[0030] The techniques, methods, and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and devices should be considered as part of the specification.

[0031] As Figures 1 to 5 shown, embodiment one shows a glass punching cutter assembly, which comprises a cutter connecting rod structure 10 and a cutter structure 20. The first end of the cutter connecting rod structure 10 has a cooling liquid inlet 11, and the second end of the cutter connecting rod structure 10 has a cooling liquid outlet 12 in the side wall, which is in communication with the cooling liquid inlet 11. The first end of the cutter structure 20 is sealingly connected to the outer wall of the cutter connecting rod structure 10, and the second end of the cutter structure 20 extends away from the first end of the cutter connecting rod structure 10. The cooling liquid outlet 12 is located in the cutter structure 20, and the outer wall of the cutter connecting rod structure 10 and the inner wall of the cutter structure 20 have a predetermined distance.

[0032] By applying the technical solution of embodiment one, the first end of the cutter connecting rod structure 10 has a cooling liquid inlet 11, and the cooling liquid inlet 11 admits liquid. The second end of the cutter connecting rod structure 10 has a cooling liquid outlet 12 in the side wall, which discharges liquid. The cooling liquid outlet 12 is located in the cutter structure 20, so that the cooling liquid is thrown outward under the combined action of external pressure and centrifugal force, and forms splashing or downward flow when encountering the blockage of the cutter structure 20, thus playing a cooling role on the cutter structure 20 and a flushing role on the ground powder. The technical solution of embodiment one effectively solves the problem that the cooling liquid pipe is prone to misalignment and inconvenient to use in the prior art.

[0033] It should be noted that the second end of the tool connecting rod structure 10 is closed, and the tool connecting rod structure 10 and the tool structure 20 are integrally formed.

[0034] As shown in the technical scheme of embodiment one, the cooling liquid outlet 12 is inclined downward in the direction from the central axis of the tool connecting rod structure 10 to the outer wall of the tool connecting rod structure 10. In this way, the cooling effect of the cooling liquid on the cutting edge of the tool structure 20 can be ensured. Figure 5 As shown in the technical scheme of embodiment one, the radial distance between the outer wall of the tool connecting rod structure 10 and the inner wall of the tool structure 20 is d, the shortest distance between the cooling liquid outlet 12 and the cutting edge of the tool structure 20 is L, and the included angle between the shortest line connecting the cooling liquid outlet 12 and the cutting edge of the tool structure 20 and the inner wall of the tool structure 20 is θ, wherein θ = arc tan(d / L). Such a structure arrangement makes the utilization rate of the cooling liquid higher, and most of the cooling liquid will impact the cutting edge of the tool structure 20. In addition, the above structure has a good flushing effect on the grinding powder, so that the glass punching tool assembly has a better machining effect on the glass.

[0035] Figure 5 In the technical scheme of embodiment one, d is in the range of 3mm to 6mm, and L is in the range of 4mm to 16mm. Such a structure can not only ensure that the tool structure 20 has a certain rigidity, but also ensure that the cooling and flushing effect of the tool structure 20 is good.

[0036] It should be noted that, as shown in the technical scheme of embodiment one, the cooling liquid outlet 12 has multiple layers in the axial direction of the tool connecting rod structure 10, that is, the cooling liquid outlet 12 is not only arranged in the circumferential direction, but also arranged in the axial direction of up and down. The above-mentioned included angle θ is the included angle of the bottom layer of the cooling liquid outlet 12. In this way, the cooling liquid outlet 12 in the upper layer can cool and flush the tool structure 20 through flow. Or when the speed is low, or the pressure of the cooling liquid is low, the bottom layer of the cooling liquid outlet 12 cannot reach the cutting edge of the tool structure 20, and the cooling liquid of the cooling liquid outlet 12 above can reach the cutting edge position of the tool structure 20.

[0037] It should be noted that, as shown in the technical scheme of embodiment one, the cooling liquid outlet 12 gradually increases in the circumferential direction of the tool connecting rod structure 10 from the inside to the outside. The above-mentioned structure arrangement can ensure that the cooling liquid is less splashed, and the cooling and flushing effect can also be ensured. It should be noted that the inner port of the cooling liquid outlet 12 is 1 / 2 of the outer port of the cooling liquid outlet 12. The entire cooling liquid outlet has a certain thickness, and the above-mentioned included angle θ is measured with the outer port of the cooling liquid outlet 12. Figure 4 As shown in the technical scheme of embodiment one, the radial distance between the outer wall of the tool connecting rod structure 10 and the inner wall of the tool structure 20 is d, the shortest distance between the cooling liquid outlet 12 and the cutting edge of the tool structure 20 is L, and the included angle between the shortest line connecting the cooling liquid outlet 12 and the cutting edge of the tool structure 20 and the inner wall of the tool structure 20 is θ, wherein θ = arc tan(d / L). Such a structure arrangement makes the utilization rate of the cooling liquid higher, and most of the cooling liquid will impact the cutting edge of the tool structure 20. In addition, the above structure has a good flushing effect on the grinding powder, so that the glass punching tool assembly has a better machining effect on the glass.

[0038] As shown in the technical scheme of embodiment one, the radial distance between the outer wall of the tool connecting rod structure 10 and the inner wall of the tool structure 20 is d, the shortest distance between the cooling liquid outlet 12 and the cutting edge of the tool structure 20 is L, and the included angle between the shortest line connecting the cooling liquid outlet 12 and the cutting edge of the tool structure 20 and the inner wall of the tool structure 20 is θ, wherein θ = arc tan(d / L). Such a structure arrangement makes the utilization rate of the cooling liquid higher, and most of the cooling liquid will impact the cutting edge of the tool structure 20. In addition, the above structure has a good flushing effect on the grinding powder, so that the glass punching tool assembly has a better machining effect on the glass.

[0039] Figure 4 ​​As shown, in the technical solution of Embodiment 1, there are multiple coolant outlets 12, which are arranged circumferentially along the tool connecting rod structure 10. This structure allows the coolant to cool the cutting edge of the tool structure 20 as uniformly as possible.

[0040] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the second end of the tool structure 20 has multiple grooves. The multiple grooves ensure a cooling effect and allow grinding powder to be flushed out through the gaps between the grooves. Coolant can flow out through the multiple grooves, carrying away heat and cooling as it flows out, and also carrying away the grinding powder.

[0041] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, multiple grooves are evenly spaced apart along the circumference of the tool structure 20. This structure is easy to process, has good performance, and eliminates concerns about uneven grinding.

[0042] The difference between the technical solution of Embodiment 2 and Embodiment 1 is that the inclination direction of the coolant outlets 12 of both the upper and lower layers is towards the cutting edge (i.e., the grinding position) of the tool structure 20. This results in a greater scouring intensity, and the tool assembly of Embodiment 1 or Embodiment 2 can be selected according to specific circumstances.

[0043] The glass drilling tool assembly of Embodiment 2 includes a tool link structure 10 and a tool structure 20. The first end of the tool link structure 10 has a coolant inlet 11, and the second end of the tool link structure 10 has a coolant outlet 12 on its sidewall. The coolant inlet 11 and the coolant outlet 12 are connected. The first end of the tool structure 20 is closedly connected to the outer wall of the tool link structure 10, and the second end of the tool structure 20 extends away from the first end of the tool link structure 10. The coolant outlet 12 is located inside the tool structure 20, and the outer wall of the tool link structure 10 and the inner wall of the tool structure 20 are at a predetermined distance.

[0044] Applying the technical solution of Embodiment 2, the first end of the tool connecting rod structure 10 has a coolant inlet 11 for coolant inflow. The second end sidewall of the tool connecting rod structure 10 has a coolant outlet 12 for coolant outflow. The coolant outlet 12 is located inside the tool structure 20. Thus, under the combined action of external pressure and centrifugal force, the coolant is thrown outwards. Upon encountering the obstruction of the tool structure 20, it splashes or flows downwards, thereby cooling the tool structure 20 and washing away the grinding powder. The technical solution of Embodiment 2 effectively solves the problem of easy misalignment of the coolant pipe and inconvenience in use in the prior art.

[0045] According to another aspect of the present application, there is also provided a glass drilling apparatus comprising a machine tool assembly and a glass drilling tool assembly mounted on the machine tool assembly, the glass drilling tool assembly being the glass drilling tool assembly described above. It is to be noted that the machine tool assembly described above is a machine tool assembly with a cooling line which exists in the prior art. The machine tool assembly and the glass drilling tool assembly can be used even if some leakage of the coolant occurs.

[0046] In the embodiments of the present application, the machine tool assembly comprises a machine tool structure and a chuck structure, and the chuck structure is mounted on the machine tool structure. The chuck structure can be used to position and / or fix the glass. Moreover, the chuck structure is not easy to scratch and damage the glass.

[0047] So far, the embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details which are well known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.

[0048] Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, but not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified or some technical features can be replaced equivalently without departing from the scope and spirit of the present application. In particular, the technical features mentioned in each embodiment can be combined in any way as long as there is no structural conflict.
