[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0045] like Figures 1 to 4 As shown, a spindle adjustment mechanism provided by an embodiment of the utility model is used for adjusting the position of the spindle. The spindle adjustment mechanism includes a mounting seat 1, a sleeve 2 and an adjustment component 3. The mounting seat 1 has an inner cavity, the sleeve 2 is inserted in the inner cavity, the sleeve 2 and the inner cavity are clearance-matched, the sleeve 2 is used to be sleeved on the outer periphery of the spindle 5 of the PCB processing equipment, and the position of the sleeve 2 can be adjusted by the adjustment component 3, thereby adjusting the position of the spindle 5.

[0046] The mounting seat 1 is fixedly mounted on the PCB processing equipment, and the inner cavity penetrates the mounting seat 1 along the axial direction of the main shaft 5. The main shaft 5 can move up and down in the sleeve 2 along the axial direction to process the PCB board. The PCB processing equipment can be a drilling machine or a drilling and gong integrated machine.

[0047] The adjustment component 3 includes a fixed component 31, a movable part 32 and an adjustment component 33. The fixed component 31 is installed on the mounting seat 1, the movable part 32 is connected to the sleeve 2, one end of the adjustment component 33 is rotatably connected to the fixed component 31 and is a clearance fit, and the other end of the adjustment component 33 is threadedly connected to the movable part 32. It has a simple structure and a low difficulty in the assembly process. When adjusting the main shaft, the movable part 32 can be driven to move back and forth by rotating the adjustment component 33, and the movable part 32 drives the sleeve 2 connected thereto to move within a predetermined plane, thereby driving the main shaft 5 to follow the sleeve 2 to move, so as to adjust the position of the main shaft 5.

[0048] In this embodiment, an adjusting member 33 is connected between the fixed component 31 and the movable member 32. When the positions of the shaft sleeve 2 and the spindle 5 need to be fine-tuned, the adjusting member 33 is screwed to rotate the adjusting member 33. The threaded cooperation between the adjusting member 33 and the movable member 32 drives the movable member 32 to move in one direction, thereby achieving the purpose of moving the shaft sleeve 2 and the spindle 5 in one direction. By controlling the rotation angle of the adjusting member 33, the moving distance of the movable member 32 can be accurately adjusted, and then the moving distance of the shaft sleeve 2 and the spindle 5 can be accurately adjusted, thereby improving the adjustment accuracy of the spindle 5 of the PCB processing equipment, so that the spacing between multiple spindles 5 meets the requirements, reducing the misalignment of the processing holes on the PCB board, and reducing the scrapping of the PCB board. Furthermore, when adjusting through the adjusting member 33, the adjustment can be completed through only one threaded pair. The adjustment process is simple and fast. While ensuring the adjustment accuracy, the adjustment efficiency of the main shaft can also be improved. In addition, there is a clearance fit between the adjusting member 33 and the fixed component 31, and a threaded connection between the adjusting member 33 and the movable member 32, which makes the installation of the adjusting member 33 simple, the installation difficulty is low, and the assembly efficiency is improved.

[0049] In one embodiment, if Figure 3 As shown, the spindle adjustment mechanism also includes a limit assembly 4, which is connected to the adjustment member 33. The limit assembly 4 is used to limit the relative movement of the adjustment member 33 and the fixed assembly 31 in the axial direction of the adjustment member 33. Under the limiting action of the limit assembly 4, the adjustment member 33 can only rotate on its own but cannot move in the axial direction, which facilitates the realization of the adjustment function and improves the adjustment efficiency.

[0050] In one embodiment, if Figure 3As shown, the limiting component 4 includes a first limiting member 41 and a second limiting member 42, which are arranged on both sides of the fixed component 31, the first limiting member 41 is sleeved on the adjusting member 33 and is located between the movable member 32 and the fixed component 31, the first limiting member 41 and the adjusting member 33 are relatively fixed, for example, there is an interference fit between the first limiting member 41 and the adjusting member 33, when the adjusting member 33 rotates, the first limiting member 41 rotates with the adjusting member 33, and the first limiting member 41 can abut against the fixed component 31 to limit the relative movement of the adjusting member 33 and the fixed component 31. The second limiting member 42 is connected to the end of the adjusting member 33 away from the movable member 32, and the second limiting member 42 can abut against the fixed component 31, specifically, the surface of the fixed component 31 on the side away from the movable member 32, to limit the relative movement of the adjusting member 33 and the fixed component 31. The position of the adjusting member 33 is limited by the first limiting member 41 and the second limiting member 42, so that the adjusting member 33 cannot move in the axial direction when the adjusting member 33 is rotated. In a feasible embodiment, the second limiting member 42 and the adjusting member 33 are an integrated structure.

[0051] In one embodiment, if Figure 3 As shown, the adjusting member 33 includes a first connecting section 331 and a second connecting section 332 connected to each other, the first connecting section 331 is provided with an external thread, the movable member 32 is provided with an internal thread matching the external thread, the first connecting section 331 is threadedly connected to the movable member 32, and the second connecting section 332 is rotatably connected to the fixed assembly 31. When the adjusting member 33 is rotated, the adjusting member 33 can rotate relative to the fixed assembly 31, and the first connecting section 331 can drive the movable member 32 to move along the axial direction of the adjusting member 33.

[0052] The diameter of the second connecting section 332 is larger than the diameter of the first connecting section 331, so as to form a first step 333 at the connection between the second connecting section 332 and the first connecting section 331. The first stopper 41 is sleeved on the outer periphery of the first connecting section 331 and abuts against the first step 333. The second stopper 42 is connected to one end of the second connecting section 332 away from the first connecting section 331. By setting the diameters of the first connecting section 331 and the second connecting section 332 to be different, the first step 333 is formed at the intersection of the first connecting section 331 and the second connecting section 332, so as to facilitate limiting the installation position of the first stopper 41 on the adjusting member 33, that is, when the first stopper 41 is installed to abut against the first step 333, the first stopper 41 is installed in place, so as to reduce the difficulty of installation. At the same time, the first step 333 can also limit the adjusting member 33 along the axial direction of the adjusting member 33 when the adjusting member 33 is rotated.

[0053] In a preferred embodiment, the adjusting member 33 is a screw rod, and the second limiting member 42 is a nut of the screw rod. The adjusting structure is simple and the cost is low. The screw rod does not have high requirements for thread matching during installation and adjustment, and the assembly difficulty is low.

[0054] In one embodiment, the fixing assembly 31 is provided with a first connecting hole 3121 and a second connecting hole 3122 which are connected to each other along the axial direction of the adjusting member 33, and the first connecting hole 3121 is located at one end of the second connecting hole 3122 close to the movable member 32. The diameter of the first connecting hole 3121 is larger than the diameter of the second connecting hole 3122, so as to form a second step 3123 at the intersection of the first connecting hole 3121 and the second connecting hole 3122 inside the fixing assembly 31, the first connecting hole 3121 is closer to the movable member 32 than the second connecting hole 3122, the first stopper 41 and one end of the first connecting section 331 close to the second connecting section 332 are accommodated in the first connecting hole 3121, the first stopper 41 and the first connecting hole 3121 are clearance-matched, and the first stopper 41 can abut against the second step 3123. The second connecting section 332 is located in the second connecting hole 3122 and is a clearance fit. The adjusting member 33 passes through the first connecting hole 3121 and the second connecting hole 3122 in sequence and then abuts against the second limiting member 42. The second limiting member 42 is located outside the second connecting hole 3122 and abuts against an end of the fixing component 31 away from the movable member 32.

[0055] Since the first limit member 41 can abut against the second step 3123, when the adjusting member 33 is rotated to adjust the spindle position, the first limit member 41 can stop the adjusting member 33 from moving in a direction away from the movable member 32, and the second limit member 42 abuts against the fixed assembly 31, and can stop the adjusting member 33 from moving in a direction close to the movable member 32.

[0056] In some feasible embodiments, in the axial direction of the adjusting member 33, the distance between the first step 333 and the second stopper 42 is greater than or equal to the distance between the second step 3123 and the second stopper 42. Specifically, the distance between the first step 333 and the second stopper 42 may be equal to the distance between the second step 3123 and the second stopper 42, so that the second step 3123 does not interfere with the installation of the first stopper 41. Alternatively, the distance between the first step 333 and the second stopper 42 may be greater than the distance between the second step 3123 and the second stopper 42, so that a matching gap is formed between the first stopper 41 and the second step 3123, so as to avoid interference with the rotation of the first stopper 41 following the adjusting member 33, thereby ensuring the stability of the adjustment.

[0057] In one embodiment, if Figure 3As shown, the fixing assembly 31 is further provided with a third connection hole 3124 along the axial direction of the adjusting member 33, and the third connection hole 3124 is connected to both the first connection hole 3121 and the second connection hole 3122. The third connection hole 3124 is located at one end of the first connection hole 3121 away from the second connection hole 3122, and the diameter of the third connection hole 3124 is greater than the diameter of the first connection hole 3121.

[0058] In the process of installing the adjusting member 33, the adjusting member 33 is first inserted into the first connecting hole 3121 and the second connecting hole 3122 until the second connecting section 332 is located in the second connecting hole 3122 and the second stopper 42 abuts against the end of the fixing assembly 31 away from the movable member 32, and then the first stopper 41 is sleeved on the first connecting section 331, and the first stopper 41 is assembled to the position abutting against the first step 333 and located in the first connecting hole 3121 by knocking or other processes, thereby completing the installation of the adjusting member 33. By providing the third connecting hole 3124 having a diameter larger than the first connecting hole 3121, the knocking assembly process of the first stopper 41 is facilitated, and the difficulty of installation is reduced.

[0059] In one embodiment, if Figure 3 As shown, the fixing assembly 31 includes a first fixing block 311 and a second fixing block 312. The first fixing block 311 is installed on the mounting seat 1. The first fixing block 311 is provided with a mounting cavity for installing the second fixing block 312. The second fixing block 312 is tightly matched with the first fixing block 311, so that the second fixing block 312 is relatively fixed to the first fixing block 311. The first connecting hole 3121 and the second connecting hole 3122 are both provided on the second fixing block 312. By dividing the fixing block into two parts, the first fixing block 311 and the second fixing block 312, the assembly connection between the adjusting assembly 3 and the fixing assembly 31 and the movable part 32 is facilitated.

[0060] In one embodiment, if Figure 3 , Figure 4 As shown, the movable part 32 includes a movable part body 321 and a tongue 322 connected to the movable part body 321. A limiting groove 21 is provided on the shaft sleeve 2. One end of the tongue 322 away from the movable part body 321 is provided in the limiting groove 21. The movable part 32 is connected to the shaft sleeve 2 through the cooperation between the tongue 322 and the limiting groove 21. When the adjusting part 33 drives the movable part 32 to move, it can drive the shaft sleeve 2 to move together.

[0061] The sleeve 2 includes a sleeve body 22 and a flange 23 disposed at one end of the sleeve body 22. The flange 23 extends from the outer edge of the sleeve body 22 in a direction away from the central axis of the sleeve 2. The sleeve body 22 is disposed in the inner cavity of the mounting seat 1. The flange 23 abuts against the mounting seat 1. Figure 2At the upper end of the orientation shown, the limiting groove 21 is arranged on a side surface of the flange 23 facing the mounting seat 1 .

[0062] In one embodiment, if Figure 3 As shown, the mounting seat 1 is provided with a receiving groove 11, which is provided at one end of the mounting seat 1 facing the movable member 32 and passes through one end of the mounting seat 1 facing the flange 23 of the sleeve 2, and the movable member body 321 is accommodated in the receiving groove 11, and the tongue 322 extends from the receiving groove 11 and fits in the limiting groove 21. The movable member body 321 is arranged between the mounting seat 1 and the fixed assembly 31, and driven by the adjusting member 33, the movable member 32 moves in the receiving groove 11, which can limit the moving range of the movable member 32, and at the same time can also improve the overall compactness of the spindle 5 adjustment mechanism and reduce the overall volume.

[0063] In one embodiment, the adjustment assembly 3 includes a first adjustment assembly 3a and a second adjustment assembly 3b both mounted on the mounting base 1. The first adjustment assembly 3a is used to drive the main shaft 5 to move in a first direction, and the second adjustment assembly 3b is used to drive the main shaft 5 to move in a second direction, and the first direction and the second direction intersect.

[0064] The first adjustment component 3a and the second adjustment component 3b are arranged on the mounting seat 1, which can adjust the position of the main shaft 5 in the first direction and the second direction, thereby reducing the error caused by the manufacture or assembly of the workpiece.

[0065] In a specific embodiment, if Figure 1 As shown, the first direction is the X direction, the second direction is the Y direction, the first direction is perpendicular to the second direction, when adjusting the position of the sleeve 2 in the X direction, the adjusting member 33 of the first adjusting assembly 3a rotates, which can drive the movable member 32 of the first adjusting assembly 3a to move along the X direction, thereby driving the sleeve 2 and the spindle 5 to move in the X direction. When adjusting the position of the sleeve 2 in the Y direction, the adjusting member 33 of the second adjusting assembly 3b rotates, which can drive the movable member 32 of the second adjusting assembly 3b to move along the Y direction, thereby driving the sleeve 2 and the spindle 5 to move in the Y direction.

[0066] It is understandable that when the position of the spindle 5 in the X direction or the Y direction does not meet the requirements, the adjustment in one direction can be achieved by adjusting the first adjustment component 3a or the second adjustment component 3b. When the position of the spindle 5 in both the X direction and the Y direction does not meet the requirements, the first adjustment component 3a and the second adjustment component 3b can be used to achieve adjustment at any position on the XY plane, thereby improving the adjustment accuracy and having a larger application range, thereby reducing the occurrence of low accuracy or misalignment when processing PCB boards.

[0067] In one embodiment, if Figure 3 , Figure 4As shown, the limiting groove 21 includes a first limiting groove 211 and a second limiting groove 212. The tongue 322 of the first adjusting component 3a is arranged in the first limiting groove 211. When the adjusting member 33 of the first adjusting component 3a is rotated, the movable member 32 of the first adjusting component 3a moves along the first direction. The tongue 322 of the first adjusting component 3a can drive the sleeve 2 and the main shaft 5 to move along the first direction, thereby adjusting the position of the main shaft 5 in the first direction. The tongue 322 of the second adjusting component 3b is arranged in the second adjusting groove. When the adjusting member 33 of the second adjusting component 3b is rotated, the movable member 32 of the second adjusting component 3b moves along the second direction. The tongue 322 of the second adjusting component 3b can drive the sleeve 2 and the main shaft 5 to move along the second direction, thereby adjusting the position of the main shaft 5 in the second direction.

[0068] In the first direction, the tongue 322 of the first adjustment component 3a abuts against the groove wall of the first limiting groove 211, so that when the movable member 32 of the first adjustment component 3a moves along the first direction, the sleeve 2 can be driven to move along with it. In the second direction, the tongue 322 of the second adjustment component 3b abuts against the groove wall of the second limiting groove 212, so that when the movable member 32 of the second adjustment component 3b moves along the second direction, the sleeve 2 can be driven to move along with it.

[0069] Among them, Figure 4 As shown, the extension direction of the first limiting groove 211 is different from the extension direction of the second limiting groove 212. The first limiting groove 211 extends along the second direction. When the tongue 322 of the second adjustment component 3b drives the sleeve 2 to move along the second direction, the tongue 322 of the first adjustment component 3a can slide along the first limiting groove 211 to prevent the tongue 322 of the first adjustment component 3a from affecting the movement of the sleeve 2 in the second direction. And due to the abutment between the tongue 322 of the first adjustment component 3a and the first limiting groove 211 in the first direction, the sleeve 2 can only move along the second direction driven by the tongue 322 of the second adjustment component 3b, and remains unchanged in the first direction.

[0070] The second limiting groove 212 extends along the first direction, and when the tongue 322 of the first adjusting component 3a drives the shaft sleeve 2 to move along the first direction, the tongue 322 of the second adjusting component 3b can slide along the second limiting groove 212 to prevent the tongue 322 of the second adjusting component 3b from affecting the movement of the shaft sleeve 2 in the first direction.
