In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0047] This embodiment provides a boring bar support device. Refer to Figures 1 to 9 As shown, the boring bar support device includes a base 1, an adjustment assembly 2, and a fixing assembly 3. Among them, the base 1 is provided with a guide rail 11 along a first direction. The adjustment assembly 2 includes a first slider 21, a second slider 22, and an adjusting member. The first slider 21 and the second slider 22 are arranged on the base 1 at intervals along the first direction. Both the first slider 21 and the second slider 22 are slidably connected to the guide rail 11. The end of the first slider 21 and the end of the second slider 22 are respectively provided with a first abutting member 23 and a second abutting member 24. The first abutting member 23 and the second abutting member 24 are used to jointly support the boring bar 6, and the supporting end surfaces of the first abutting member 23 and the second abutting member 24 are both tangent to the outer surface of the boring bar 6. The adjusting member is used to adjust the distance between the first slider 21 and the second slider 22 and fix the first slider 21 and the second slider 22 after the adjustment is in place. The fixing assembly 3 is used to fix the second slider 22 and the base 1.

[0048] In this embodiment, when the boring bar support device is in use, first, the base 1 is sleeved on the support mounting shaft of the processing machine tool, and the position of the base 1 relative to the support mounting shaft is controlled so that when the boring bar 6 is fixed subsequently, the support mounting shaft can be located above the boring bar 6, and the first abutting member 23 and the second abutting member 24 can be located on both sides of the boring bar 6. Subsequently, the boring bar 6 is fixed to the processing machine tool. The boring bar 6 is located between the first abutting member 23 and the second abutting member 24. The distance between the first slider 21 and the second slider 22 is adjusted by the adjusting member, so that the first slider 21 and the second slider 22 slide relative to the guide rail 11 to adapt to boring bars 6 of different diameter sizes, so that the supporting end surfaces of the first abutting member 23 and the second abutting member 24 are in a tangential abutting position with the outer surface of the corresponding size boring bar 6. After the positions of the first slider 21 and the second slider 22 are adjusted, the first slider 21 and the second slider 22 are fixed by the adjusting member, and the first slider 21 and the second slider 22 are fixed by the fixing assembly 3, so as to realize the fixation of the base 1, the first slider 21, and the second slider 22, and realize reliable and stable support for the boring bar 6. This device can meet the support requirements of boring bars 6 of different diameter sizes, and has strong applicability and use compatibility.

[0049] Specifically, the first abutting member 23 and the second abutting member 24 are symmetrically arranged.

[0050] Specifically, the supporting end surface of the first abutting member 23 and the supporting end surface of the second abutting member 24 are inclined downward from top right to bottom in a direction approaching each other. The supporting end surfaces of the first abutting member 23 and the second abutting member 24 together form a V-shaped supporting structure.

[0051] Optionally, both the first abutting member 23 and the second abutting member 24 are set as high-hardness and high-precision bearings. The bearing on the first abutting member 23 can rotate relative to the first abutting member 23, and the bearing on the second abutting member 24 can rotate relative to the second abutting member 24. The side end surfaces of the two bearings are the supporting end surfaces for jointly supporting the boring bar 6. With such a setting, during the conveying process of the boring bar 6, the boring bar 6 is in rolling contact with the two bearings, reducing the frictional resistance during the feeding process of the boring bar 6 and protecting the boring bar 6 from being damaged by friction.

[0052] As an alternative embodiment, rubber buffer pads are provided on the supporting end surfaces of the first abutting member 23 and the second abutting member 24. With such a setting, it can buffer the hard contact between the supporting end surfaces of the first abutting member 23 and the second abutting member 24 and the outer surface of the boring bar 6, and avoid damaging the outer surface of the boring bar 6.

[0053] Specifically, the first slider 21 and the second slider 22 move away from each other in the first direction, such that the supporting end faces of the first abutting member 23 and the second abutting member 24 gradually move away from each other. At this time, it can correspondingly support a boring bar 6 with a larger diameter. The first slider 21 and the second slider 22 move closer to each other in the first direction, such that the supporting end faces of the first abutting member 23 and the second abutting member 24 gradually move closer to each other. At this time, it can correspondingly support a boring bar 6 with a smaller diameter.

[0054] In this embodiment, the adjusting member includes a screw rod 25. The screw rod 25 has a first threaded section 251 and a second threaded section 252. The first threaded section 251 and the second threaded section 252 have opposite helix directions. The first slider 21 is provided with a first threaded hole 211, and the second slider 22 is provided with a second threaded hole 221. The screw rod 25 passes through the first threaded hole 211 and extends into the second threaded hole 221. The first threaded hole 211 is threadedly connected to the first threaded section 251, and the second threaded hole 221 is threadedly connected to the second threaded section 252. Specifically, when the first slider 21 and the second slider 22 are slidably connected to the base 1, by rotating the screw rod 25, since the first threaded hole 211 is threadedly connected to the first threaded section 251, the second threaded hole 221 is threadedly connected to the second threaded section 252, and the first threaded section 251 and the second threaded section 252 have opposite helix directions, it will drive the first slider 21 and the second slider 22 to move in the first direction simultaneously towards or away from each other, thereby adjusting the distance between the first slider 21 and the second slider 22. The structure is simple and the operation is convenient.

[0055] In some other alternative embodiments, the adjusting member may further include a telescopic cylinder (not shown) disposed between the first slider 21 and the second slider 22. Specifically, one of the cylinder body and the cylinder rod of the telescopic cylinder is disposed on the first slider 21, and the other is disposed on the second slider 22. The cylinder rod of the telescopic cylinder expands and contracts relative to the cylinder body, thereby being able to drive the first slider 21 and the second slider 22 to move in the first direction simultaneously towards or away from each other. Similar driving components may also be components with telescopic adjustment functions such as electric telescopic rods, which can automatically adjust the distance between the first slider 21 and the second slider 22 compared with the arrangement of the screw rod 25.

[0056] In this embodiment, the guide rail 11 is provided in a dovetail shape. The first slider 21 is provided with a first dovetail groove 212 slidably connected to the guide rail 11, and the second slider 22 is provided with a second dovetail groove 223 slidably connected to the guide rail 11. The cooperation of the guide rail 11 with the first dovetail groove 212 and the second dovetail groove 223 not only ensures that the first slider 21 and the second slider 22 slide on the base 1, but also can prevent the first slider 21 and the second slider 22 from accidentally coming off, ensuring the reliability and stability of the sliding.

[0057] Optionally, the base 1 is made of high-strength steel.

[0058] In this embodiment, the fixing assembly 3 includes a fixing block 31 and a fixing screw 32. The fixing block 31 is fixedly arranged on the base 1. The second slider 22 is located between the first slider 21 and the fixing block 31 in the first direction. The fixing block 31 is provided with a third screw hole 311, and the second slider 22 is provided with a fourth screw hole 222. The fixing screw 32 passes through the third screw hole 311 and extends into the fourth screw hole 222, and the fixing screw 32 is threadedly connected to the third screw hole 311 and the fourth screw hole 222. Specifically, after the positions of the first slider 21 and the second slider 22 are fixed, the fixing screw 32 passes through the third screw hole 311 and extends into the fourth screw hole 222, and the fixing screw 32 is threadedly connected to the third screw hole 311 and the fourth screw hole 222, so as to realize the fixation of the base 1, the first slider 21, and the second slider 22, and realize a reliable and stable support for the boring bar 6.

[0059] Specifically in this embodiment, the fourth screw hole 222 communicates with the second screw hole 221, and the second screw hole 221, the third screw hole 311, and the fourth screw hole 222 are coaxially arranged. Specifically, the fourth screw hole 222 communicates with the second screw hole 221 and has the same thread helix direction, that is, the fourth screw hole 222 and the second screw hole 221 can be set as a hole structure. The screw rod 25 and the fixing screw 32 are respectively threadedly connected to opposite sides in the axial direction of this hole structure.

[0060] In this embodiment, it further includes a first nut 41 and a second nut 42. The first nut 41 is located on the side of the first slider 21 facing away from the second slider 22. The first nut 41 is sleeved on the screw rod 25 and is threadedly connected to the first threaded section 251. The second nut 42 is located on the side of the fixing block 31 facing away from the second slider 22. The second nut 42 is sleeved on the fixing screw 32 and is threadedly connected to the fixing screw 32. Specifically, the setting of the first nut 41 can firmly lock the screw rod 25 on the first slider 21, and the setting of the second nut 42 can firmly lock the fixing screw 32 on the fixing block 31.

[0061] In this embodiment, the fixing assembly 3 further includes a connecting screw 33. The fixing block 31 is provided with a first mounting hole, and the base 1 is correspondingly provided with a second mounting hole 12. The connecting screw 33 passes through the first mounting hole and is threadedly connected to the second mounting hole 12. The reliable fixation between the fixing block 31 and the base 1 can be realized through the connecting screw 33, and the structure is simple and the connection is convenient.

[0062] In this embodiment, the boring bar support device further includes a first gasket 51 and a second gasket 52. The first gasket 51 is used to be clamped between the first slider 21 and the second slider 22, and the second gasket 52 is used to be clamped between the second slider 22 and the fixed block 31. The numbers of the first gasket 51 and the second gasket 52 are respectively provided with a plurality, and the thicknesses of the plurality of first gaskets 51 and the plurality of second gaskets 52 are both set to be different. Specifically, the thicknesses of the plurality of first gaskets 51 and the plurality of second gaskets 52 respectively adapt to a plurality of boring bars 6 with different diameter sizes, that is, the first gasket 51, the second gasket 52 and the boring bar 6 need to be arranged in one-to-one correspondence. When a boring bar 6 to be supported with a certain diameter size has been obtained, the first gasket 51 with the corresponding thickness is placed between the first slider 21 and the second slider 22, and the second gasket 52 with the corresponding thickness is placed between the second slider 22 and the fixed block 31, which can save the complicated adjustment process and directly adjust the positions of the first slider 21 and the second slider 22 to positions adapted to the boring bar 6 with the corresponding diameter size, further improving the adjustment efficiency. In addition, the first gasket 51 fills the gap between the first slider 21 and the second slider 22, and the second gasket 52 fills the gap between the second slider 22 and the fixed block 31, which also makes the whole device more reliable and stable.

[0063] In this embodiment, the base 1 is provided with a keyway hole 13 along the first direction, and the keyway hole 13 is used to be connected with the bracket mounting shaft of the processing machine tool. Specifically, the bracket mounting shaft of the processing machine tool extends along the first direction, and the base 1 is sleeved on the bracket mounting shaft through the keyway hole 13 and can slide relative to the bracket mounting shaft. With such a setting, the position of the base 1, that is, the whole boring bar support device along the first direction can be adjusted, realizing flexible adjustment of the overall position of the device.

[0064] Refer to Figures 1 to 10 As shown, this embodiment also provides a boring bar support method. The boring bar support method includes the above-mentioned boring bar support device, and the boring bar support method includes the following steps:

[0065] S100. Sleeve the base 1 on the bracket mounting shaft of the processing machine tool, control the base 1 to slide relative to the bracket mounting shaft, so that the base 1 moves above the boring bar 6 to be supported, and the symmetry axis of the first abutting member 23 and the second abutting member 24 passes through the center of the boring bar 6;

[0066] S200. Fix the boring bar 6 on the processing machine tool, and the boring bar 6 is located between the first abutting member 23 and the second abutting member 24;

[0067] S300. The adjusting member adjusts the distance between the first slider 21 and the second slider 22, so that the first abutting member 23 and the second abutting member 24 jointly support the boring bar 6, and fix the first slider 21 and the second slider 22 through the adjusting member;

[0068] The S400 and the fixing component 3 fix the second slider 22 and the base 1.

[0069] In step S100, the base 1 is sleeved on the bracket mounting shaft through the keyway hole 13 and slides relative to the bracket mounting shaft, so as to adjust the position of the base 1, and move the base 1 to a position where the symmetry axis of the first abutting member 23 and the second abutting member 24 passes through the center of the boring row 6, which is convenient for the subsequent reliable abutment against the boring row 6.

[0070] In step S200, the boring row 6 is fixed on the machine tool, and the boring row 6 is located between the first abutting member 23 and the second abutting member 24, forming a state roughly as shown in Figure 1 shown in, but different from that in Figure 1 at this time, the first abutting member 23 and the second abutting member 24 are not in an abutting position state with the boring row 6.

[0071] In step S300, the operator rotates the screw 25 to drive the first slider 21 and the second slider 22 to move in the first direction simultaneously towards or away from each other, so as to adjust the distance between the first slider 21 and the second slider 22, and further make the supporting end faces of the first abutting member 23 and the second abutting member 24 be in a tangential abutting position with the outer surface of the boring row 6 with corresponding dimensions, and finally form the position state shown in Figure 1 shown in. And when the position adjustment is completed, the screw 25 is simultaneously threadedly connected to the first slider 21 and the second slider 22, and can also realize the reliable and effective fixation of the first slider 21 and the second slider 22.

[0072] Furthermore, during the adjustment process of step S300, the first gasket 51 and the second gasket 52 corresponding to the boring row 6 with the current diameter dimension can also be directly selected. The first gasket 51 with the corresponding thickness is placed between the first slider 21 and the second slider 22, and the second gasket 52 with the corresponding thickness is placed between the second slider 22 and the fixing block 31. Subsequently, the first slider 21 and the second slider 22 are controlled to move, so that the first gasket 51 is clamped between the first slider 21 and the second slider 22, and the second gasket 52 is clamped between the second slider 22 and the fixing block 31, and the reliable adjustment of the positions of the first slider 21 and the second slider 22 can also be realized.

[0073] In step S400, after the positions of the first slider 21 and the second slider 22 are fixed, the fixing screw 32 passes through the third screw hole 311 and extends into the fourth screw hole 222. The fixing screw 32 is threadedly connected to the third screw hole 311 and the fourth screw hole 222, so as to realize the fixation of the base 1, the first slider 21, and the second slider 22, and realize the reliable and stable support for the boring row 6.

[0074] After step S400, the first nut 41 and the second nut 42 can also be used. The first nut 41 is sleeved on the screw rod 25 and screwed with the first threaded section 251. The second nut 42 is sleeved on the fixing screw 32 and screwed with the fixing screw 32, which can firmly lock the screw rod 25 on the first slider 21 and firmly lock the fixing screw 32 on the fixing block 31.
