[0050] In addition, in order to improve the machining precision of the main shaft 5, a cooling member for the main shaft 5 fixing part can be provided on the main shaft 5 fixing part. The cooling member for the main shaft 5 fixing part can cool the main shaft 5 fixing part, thereby avoiding changes in volume and dimensions of the main shaft 5 fixing part and the body part due to high temperature, and further affecting the drilling precision of the main shaft 5, so that the main shaft 5 can always be perpendicular to the workbench surface.

[0051] Wherein, a fastener 4 is further included, which is used to fixedly connect the clamping body 2 and the mounting body 1. The clamping body 2 and the mounting body 1 can be fixed together through the fastener 4. Of course, the fixing method of the motor and the fixing method of the main shaft 5 in this application are not limited to this, and no specific limitation is made here.

[0052] Furthermore, in combination with Figure 3 as shown, the fastener 4 includes a pressing part 411, and the pressing part 411 drives the main shaft 5 to move relative to the clamping body along the first direction and fixes the main shaft 5 on the clamping body.

[0053] Specifically, the fine adjustment mechanism of the main shaft 5 includes the mounting body 1, the clamping body 2, the adjusting member 3 ( Figure 1 shown in Figure 1As shown in the figure, the mounting body 1 is used for fixedly connecting with the workbench. The clamping body 2 is arranged on the mounting body 1 and is used for clamping the main shaft 5. The adjusting member 3 is used for connecting the clamping body 2 and the mounting body 1 and can adjust the mounting position of the clamping body 2 on the mounting body 1. The fastening member 4 is used for fixing the clamping body 2 on the mounting body 1. During PCB drilling operation, the mounting body 1 is fixed on the workbench, and the adjusting member 3 is used to adjust the mounting position of the clamping body 2 on the mounting body 1. After adjusting to the appropriate position, the fastening member 4 is used to fix the main shaft 5 on the clamping body 2 to complete the fine adjustment of the main shaft 5. Or, during PCB drilling operation, the mounting body 1 is fixed on the workbench, the fastening member 4 is used to fix the main shaft 5 on the clamping body 2, and then the adjusting member 3 is used to adjust the mounting position of the clamping body 2 on the mounting body 1. After adjusting to the appropriate position, the fine adjustment of the main shaft 5 is completed.

[0054] Specifically: As shown in combination with Figure 3 shown, a pressing and supporting member 22 is arranged inside the clamping body 2. The pressing and supporting member 22 is arranged inside the inner circumference of the clamping body 2. The clamping body also includes multiple groups of pressing and supporting members 22. The multiple groups of pressing and supporting members 22 are fixed on the inner wall of the clamping space along the circumferential direction of the clamping space. The pressing and supporting member 22 abuts against the outer wall of the main shaft. In an embodiment, multiple groups of pressing and supporting members 22 are arranged inside the clamping body. The multiple groups of pressing and supporting members 22 are arranged at intervals along the circumferential direction of the clamping space. The main shaft is clamped and fixed through the pressing and supporting member 22. When the main shaft is fixed on the pressing and supporting member, the main shaft is pressed and fixed on the main shaft supporting member by moving the pressing part in the first direction.

[0055] Among them, the pressing part 411 includes a pressing screw hole arranged on the clamping body 2, and a connecting member that drives the main shaft 5 to move relative to the clamping body along the first direction through the pressing screw hole and fixes the main shaft 5 on the clamping body. In an embodiment, the connecting member can be a top bolt, a top screw, etc.

[0056] Preferably, a main shaft washer (not shown in the figure) is provided between the top of the main shaft 5100 and the clamping body 22. The main shaft washer is used to ensure the concentricity between the main shaft 5 and the clamping body 2 and ensure the installation accuracy of the main shaft 5. In an embodiment, the material of the main shaft washer can be rubber material. Of course, the main shaft washer can also be other soft materials, which are not limited herein.

[0057] Among them, the adjusting member 3 includes a connecting portion 31 and an adjusting portion 32. The connecting portion 31 is used for connecting the mounting body 1 and the clamping body. The adjusting portion 32 is used to adjust the positions of the clamping body and the main shaft 5 mounted on the clamping body in the first direction and the second direction. The adjusting portion 32 is arranged between the clamping body 2 and the mounting body 1.

[0058] The connecting part 31 is used to mount the clamping body 2. The mounting body 1 and the clamping body 2 are provided with positioning holes. The connecting part 31 is located between the positioning holes. The two ends of the connecting part 31 are respectively vertically accommodated in the positioning holes of the adjacent clamping body 2 and the mounting body 1, so that the mounting body 1 and the clamping body 2 are connected.

[0059] Specifically, Figure 5 Fig. shows a partial structural schematic diagram of the mounting body 1. Fig. shows a partial structural schematic diagram of the clamping body 2. In order to ensure that the clamping body 2 can be stably fixed on the mounting body 1 after the position adjustment, as Figures 2-5 shown, the mounting body 1 is provided with a plurality of first positioning holes 12, and the clamping body 2 is provided with second positioning holes 21 communicated with the first positioning holes 12. The connecting piece is passed through the first positioning holes 12 and the second positioning holes 21 to connect the mounting body 1 and the clamping body 2. In addition, the mounting body 1 is provided with a first mounting hole 13 rotatably matched with the rotating part 332, and the clamping body 2 is provided with a waist-shaped hole movably matched with the eccentric part 331. The rotation adjusting member 3 can make the outer wall of the eccentric part 331 push the inner wall of the waist-shaped hole, so that the clamping body 2 moves relative to the mounting body 1. For the design of the waist-shaped hole, on the one hand, the outer wall of the eccentric part 331 is always in contact with the inner wall of the waist-shaped hole, ensuring that the rotation of the eccentric part 331 can push the inner wall of the waist-shaped hole and further realize the movement of the clamping body 2; on the other hand, enough space should be reserved in the waist-shaped hole to ensure that the eccentric part 331 can complete a full circle of rotation and avoid the eccentric part 331 from getting stuck.

[0060] Among them, combined with Figures 2-6 ; the adjusting part 32 includes a second adjusting position 321 and a second adjusting position 322. The second adjusting position 321 is used to adjust the position of the clamping body and the main shaft 5 mounted on the clamping body in the second direction, and the second adjusting position 322 is used to adjust the position of the clamping body and the main shaft 5 mounted on the clamping body in the first direction.

[0061] When the second adjusting position 321 is slightly rotated, the clamping body and the main shaft 5 mounted on the clamping body will move slightly along the second direction; when the second adjusting position 322 is slightly rotated, the clamping body and the main shaft 5 mounted on the clamping body will move slightly along the first direction; realizing the high-precision micro-movement adjustment of the main shaft 5 in the plane.

[0062] Furthermore, the second adjusting position 321 and the second adjusting position 322 are respectively arranged on both sides of the clamping body. The second adjusting position 321 and the second adjusting position 322 both include an eccentric shaft 33. The eccentric shaft 33 includes an eccentric part 331 and a rotating part 332. The eccentric part 331 is movably matched with the clamping body 2, and the rotating part 332 is rotatably matched with the mounting body 1. Rotating the rotating part 332 can make the eccentric part 331 drive the clamping body 2 to move relative to the mounting body 1 to adjust the mounting position of the clamping body 2 in the first direction and the second direction on the mounting body 1.

[0063] Combined withFigure 2 , Figure 6 As shown, specifically, both the second adjustment position 321 and the second adjustment position 322 include a rotating part 332 and an eccentric part 331 that are eccentrically arranged. The rotating part 332 is rotationally engaged with the mounting body 1, and the eccentric part 331 is movably engaged with the clamping body 2. The rotation adjustment member 3 can cause the eccentric part 331 to drive the clamping body 2 to move relative to the mounting body 1 to adjust the mounting position of the clamping body 2 on the mounting body 1. Since the rotating part 332 and the eccentric part 331 are eccentrically arranged, when the rotation adjustment member 3 is rotated, the rotating part 332 is rotationally engaged with the mounting body 1 and the position of the rotating part 332 remains unchanged. The outer contour of the eccentric part 331 will push the clamping body 2 to move relative to the mounting body 1, thereby realizing the adjustment of the position of the clamping body 2 on the mounting body 1 and realizing the fine adjustment of the drill. Optionally, the second adjustment position 321 and the second adjustment can be eccentric pins, which are not limited herein.

[0064] According to some embodiments of the present application, a first waist-shaped hole 3211 that is movably engaged with the eccentric part 331 of the second adjustment position 321 is provided on the clamping body 2, and a second waist-shaped hole 3221 that is movably engaged with the eccentric part 331 of the second adjustment position 322 is provided on the clamping body 2. The length direction of the first waist-shaped hole 3211 extends along the first direction, and the length direction of the second waist-shaped hole 3221 extends along the second direction.

[0065] Combined with Figures 1-7 , further, rotating the second adjustment position 321 can cause the eccentric part 331 to drive the clamping body 2 to move relative to the mounting body 1 along the second direction to adjust the mounting position of the clamping body 2 in the second direction on the mounting body 1;

[0066] Rotating the second adjustment position 322 can cause the eccentric part 331 to drive the clamping body 2 to move relative to the mounting body 1 along the first direction to adjust the mounting position of the clamping body 2 in the first direction on the mounting body 1.

[0067] Combined with Figure 7 As shown, specifically, when the second adjustment position 322 is rotated, the rotating part 332 installed in the second waist-shaped hole 3221 is rotationally engaged with the mounting body 1, and the position of the rotating part 332 remains unchanged. The outer contour of the eccentric part 331 will push the clamping body 2 to move relative to the mounting body 1, that is, rotate around the central axis of the eccentric part 331. At this time, the first waist-shaped hole 3211 extends along the first direction, and the eccentric part 331 on the second adjustment position 321 can only move along the first direction in the first waist-shaped hole 3211, that is, the eccentric part 331 of the second adjustment position 321 and the first waist-shaped hole 3211 play a limiting role in the second direction, so that the clamping body cannot rotate along the second direction during the rotation process. Thus, when the second adjustment position 321 is rotated, the clamping body is adjusted along the first direction.

[0068] Similarly, combined with Figure 7; When the first adjustment position 321 is rotated, the rotating part 332 installed in the first waist-shaped hole 3211 is rotationally engaged with the installation body 1. The position of the rotating part 332 remains unchanged, and the outer contour of the eccentric part 331 will push the clamping body 2 to move relative to the installation body 1, that is, rotate around the central axis of the eccentric part 331. At this time, the second waist-shaped hole 3221 extends along the second direction. The eccentric part 331 on the second adjustment position 322 can only move along the second direction in the second waist-shaped hole 3221. That is, the eccentric part 331 of the second adjustment position 322 and the second waist-shaped hole 3221 play a limiting role in the first direction, so that the clamping body cannot rotate along the first direction during the rotation process. Thus, when the second adjustment position 321 is rotated, the clamping body is adjusted along the second direction.

[0069] Among them, in combination with Figure 6 As shown, the distance between the center of the eccentric part 331 and the center of the rotating part 332 is t, and t is the adjustable distance of the clamping body 2 in the first direction or the second direction. That is, t is the eccentric distance 34 between the rotating part 332 and the eccentric part 331

[0070] The adjustment range of the main shaft 5 is mainly determined by the eccentric distance 34 between the rotating part 332 and the eccentric part 331 of the adjusting part 3. According to the required adjustment amount t in actual production, the eccentric distance 34 can be 0.1mm, 0.15mm, 0.2mm, etc. Taking an eccentric distance 34 of every 0.05mm as a design standard, the maximum does not exceed 0.5mm. If it exceeds 0.5mm, the adjustment accuracy of this scheme will be reduced. The smaller the eccentric distance 34 between the rotating part 332 and the eccentric part 331 of the adjusting part 3, the smaller the adjustment range of the main shaft 5, but the higher the adjustment accuracy

[0071] In another embodiment, if the eccentric distance 34 between the rotating part 332 and the eccentric part 331 of the main shaft 5 is large enough, the adjustment range of the distance in the first direction and the second direction can be adjusted by the length distance of the first waist-shaped hole 3211 and the second waist-shaped hole 3221. According to the required adjustment amount in actual production, the second waist-shaped hole 3221 can be 0.1 - 10mm, etc. The smaller the adjustment range of the main shaft 5, but the higher the adjustment accuracy.
