[0037] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] like Figures 1 to 3 As shown, an embodiment of this utility model provides an adjustment component 10 for adjusting the spindle device of a PCB processing equipment. The adjustment component 10 includes a fixing member 1, a moving member 2, a first adjusting member 3, and a second adjusting member 4. The moving member 2 is used to connect with the bushing 20 of the spindle device. The fixing member 1 is used to install on the bushing seat 30, which is sleeved on the outside of the bushing 20. The fixing member 1 provides a relatively fixed reference position for the entire adjustment component 10. The moving member 2 is movably connected to the fixing member 1 along a first direction, and the adjustment component 10 can be selectively in a locked or unlocked state.

[0039] The movable component 2 is located between the bushing seat 30 and the fixed component 1. When the adjusting assembly 10 is in the unlocked state, the first adjusting component 3 is movably inserted through the fixed component 1 and connected to the movable component 2, so as to drive the movable component 2 to move along the first direction a towards the fixed component 1. The second adjusting component 4 is movably inserted through the fixed component 1 and abuts against the movable component 2, so as to drive the movable component 2 to move along the first direction a away from the fixed component 1. Since the movable component 2 is connected to the bushing, the first adjusting component 3 and the second adjusting component 4 can drive the movable component 2 to reciprocate along the first direction a, and the bushing 20 can move with the movable component 2, thereby adjusting the position of the bushing 20 in the first direction a. When the adjusting assembly 10 is in the locked state, the fixed component 1 and the movable component 2 are relatively fixed.

[0040] In the unlocked state, when the first adjusting member 3 is operated, the first adjusting member 3 applies a force to the moving member 2, causing the moving member 2 to move in one direction along the first direction a; while when the second adjusting member 4 is operated, the second adjusting member 4 applies a force opposite to that of the first adjusting member 3 to the moving member 2, causing the moving member 2 to move in the opposite direction along the first direction.

[0041] Since the bushing 20 is connected to the moving part 2, when the moving part 2 moves along the first direction a under the action of the first adjusting part 3 or the second adjusting part 4, the bushing 20 will move along with the moving part 2, thus achieving effective adjustment of the position of the bushing 20 in the first direction a. In this way, the position of the bushing 20 can be precisely adjusted in the first direction a, and the adjustment position of the bushing 20 is controllable, meeting the specific requirements for the position of the bushing 20 under different working conditions. This avoids the situation where the adjustment range of the bushing 20 is too large, leading to an uncontrollable adjustment position.

[0042] In the drilling machine, the bushing 20 is an air-bearing bushing. The bushing 20 is fitted outside the spindle, and an air gap is formed between the bushing 20 and the spindle. This air gap keeps the bushing 20 and the spindle coaxial. When the bushing 20 moves with the moving part 2, the position of the spindle will also change when the position of the bushing 20 is finely adjusted, thereby enabling fine adjustment of the machining position of the spindle and improving the machining accuracy of the spindle.

[0043] In one embodiment, such as Figure 3 As shown, the first adjusting member 3 includes a first connecting rod 31 and a first locking structure 32. The first connecting rod 31 is movably inserted through the fixed member 1 and connected to the moving member 2 along the first direction a. The first locking structure 32 is threaded to the outer periphery of the first connecting rod 31 so as to drive the first connecting rod 31 and the moving member 2 to move along the first direction a toward the fixed member 1.

[0044] The first connecting rod 31 serves to connect the fixed part 1 and the movable part 2. Under the action of the threaded connection, the first locking structure 32 can rotate relative to the first connecting rod 31 and drive the first connecting rod 31 to move along the first direction a, thereby driving the movable part 2 connected to the first connecting rod 31 to move along the first direction a towards the fixed part 1.

[0045] By rotating the first locking structure 32, a driving force is generated on the first connecting rod 31, which can push the first connecting rod 31 to make linear motion in the first direction a. When the first connecting rod 31 moves along the first direction a, it will move together with the moving part 2 connected to it, thereby realizing the adjustment of the position of the moving part 2 by the first adjusting member 3.

[0046] In one embodiment, such as Figure 3 As shown, the fixing member 1 is provided with a first through hole 11, and the first connecting rod 31 is movably inserted through the first through hole 11 along the first direction a and connected to the moving member 2. The first connecting rod 31 and the first through hole 11 are clearance-fitted, that is, there is a gap between the outer surface of the first connecting rod 31 and the wall surface of the first through hole 11. When the first adjusting member 3 drives the moving member 2 to move, and when the first locking structure 32 drives the first connecting rod 31 to move, this clearance fit allows the first connecting rod 31 to slide smoothly in the first through hole 11, so that the fixing member 1 will not interfere with the relative movement between the first locking structure 32 and the first connecting rod 31.

[0047] The movable part 2 is provided with a first connecting hole 211. The wall surface of the first connecting hole 211 has an internal thread. The first connecting rod 31 has an external thread that mates with the internal thread. During installation, the first connecting rod 31 first passes through the first through hole 11 and is threadedly connected to the first connecting hole 211, so that the first connecting rod 31 is connected to the movable part 2. When it is necessary to drive the movable part 2 to move towards the fixed part 1 along the first direction a, the first connecting rod 31 can be restricted by a tool so that it cannot rotate. Then the first locking structure 32 rotates, which is converted into the linear movement of the first connecting rod 31, thereby driving the movable part 2 and the bushing 20 to move.

[0048] In one embodiment, the first through hole 11 is a circular hole, a square hole, or an elliptical hole.

[0049] In one embodiment, the first locking structure 32 is sleeved on the outside of the first connecting rod 31. When the adjusting assembly 10 is in the locked state, the end face of the first locking structure 32 abuts against the surface of the fixing member 1 away from the moving member 2, thereby restricting the moving member 2 from moving away from the fixing member 1. When the first locking structure 32 rotates, due to the obstruction of the fixing member 1, it is equivalent to the first locking structure 32 rotating in place, allowing the first connecting rod 31 to move relative to the first locking structure 32 along the first direction a, thereby driving the moving member 2 to move closer to the fixing member 1.

[0050] Preferably, the first connecting rod 31 is a bolt, and the first locking structure 32 is a nut. After the bolt passes through the first through hole 11 and connects to the first connecting hole 211, the nut is turned so that it abuts against the fixing member 1. When the nut that fits against the fixing member 1 is rotated, due to the relative movement process, the bolt will move the moving member 2 and eventually move along the first direction a with the bushing 20.

[0051] In one embodiment, such as Figure 3 As shown, the second adjusting member 4 includes a second connecting rod 41. One end of the second connecting rod 41 is threaded to the fixed member 1, and the other end of the second connecting rod 41 abuts against the moving member 2. Since the second connecting rod 41 is threaded to the fixed member 1, rotating the second connecting rod 41 can drive the moving member 2 to move away from the fixed member 1 along the first direction a. Since the fixed member 1 remains stationary, when the second connecting rod 41 is rotated, the second connecting rod 41 can move relative to the fixed member 1 in the first direction a. The end of the second connecting rod 41 near the moving member 2 abuts against the moving member 2, so that when the second connecting rod 41 moves, it can push the moving member 2 to move away from the fixed member 1, thereby realizing the adjustment of the position of the bushing 20.

[0052] Preferably, the fixing member 1 is provided with a second connecting hole 12, and the second connecting rod 41 passes through the second connecting hole 12 and abuts against the moving member 2. The wall of the second connecting hole 12 has an internal thread, and the external thread on the second connecting rod 41 engages with the internal thread of the second connecting hole 12 to realize the linear movement of the second connecting rod 41.

[0053] In one embodiment, the second adjusting member 4 further includes a second locking structure 42, which is threadedly connected to the outer periphery of the second connecting rod 41. When the adjusting assembly 10 is in the locked state, the end face of the second locking structure 42 abuts against the side of the fixing member 1 away from the moving member 2, thereby restricting the second connecting rod 41 from moving along the first direction. The threaded connection between the second locking structure 42 and the second connecting rod 41 has a certain self-locking characteristic. Under normal circumstances, after the second locking structure 42 is screwed onto the fixing member 1 and the external force operation is stopped, the second connecting rod 41 can be locked. The friction between the threads can keep the second connecting rod 41 stable in this position, and it will not easily loosen or shift due to slight external force interference.

[0054] Preferably, the second connecting rod 41 is a bolt, and the second locking structure 42 is a nut. The bolt passes through the second connecting hole 12 and abuts against the moving part 2. By rotating the screw, the moving part 2 can be moved, and then by tightening the nut, it abuts against the fixed part 1, locking the bolt.

[0055] As an example, the adjustment assembly 10 includes a fixing member 1, a moving member 2, a first adjusting member 3, and a second adjusting member 4. The first adjusting member 3 includes a first connecting rod 31 and a first locking structure 32, and the second adjusting member 4 includes a second connecting rod 41 and a second locking structure 42.

[0056] When adjusting the movable part 2, by screwing the second connecting rod 41, under the action of the threaded connection between the second connecting rod 41 and the fixed part 1, the second connecting rod 41 moves relative to the fixed part 1 and pushes the movable part 2 to move away from the fixed part 1. When the movable part 2 moves into place, the second locking structure 42 is rotated, and the second locking structure 42 can move along the second connecting rod 41 until the second locking structure 42 abuts against the fixed part 1. After tightening the second locking structure 42, the second connecting rod 41 can be locked.

[0057] When the movable part 2 needs to move along the first direction a towards the fixed part 1, first loosen the second locking structure 42 to release the second locking structure 42 from locking the second connecting rod 41, rotate the second connecting rod 41 so that the second connecting rod 41 gradually moves away from the movable part 2 along the first direction, so as to avoid the second connecting rod 41 blocking the fixed part 1, and prepare for the subsequent movement of the movable part 2 toward the fixed part 1.

[0058] Next, the first locking structure 32 is rotated. Since the first locking structure 32 abuts against the fixed member 1, under the action of the threaded connection between the first locking structure 32 and the first connecting rod 31, relative movement is generated between the first locking structure 32 and the first connecting rod 31, generating a driving force on the first connecting rod 31. This can push the first connecting rod 31 to produce linear movement in the first direction a, thereby driving the movable member 2 connected to it to move towards the fixed member 1 in the first direction, realizing the adjustment of the movable member 2 in the first direction a, and thus realizing the effective adjustment of the position of the bushing 20 in the first direction a.

[0059] In one embodiment, such as Figure 3 As shown, the moving part 2 includes a moving body 21 and a guide part 22. The guide part 22 is disposed on one end of the moving body 21 near the bushing 20 and is used to connect the bushing 20. Through the connection between the guide part 22 and the bushing 20, the synchronous transmission of motion is realized, so that when the moving part 2 moves, it can drive the bushing 20 to move together.

[0060] The first connecting hole 211 is provided on the moving body 21, and the end of the second adjusting member 4 away from the fixing member 1 abuts against the moving body 21.

[0061] In one embodiment, the adjustment assembly further includes a guide member connected to the bushing. The guide member has a guide groove extending along the second direction b, and the guide portion 22 is slidably connected in the guide groove. The first direction a and the second direction b intersect. When the moving member 2 has movement along the second direction b, the guide groove can guide the guide portion 22.

[0062] In one embodiment, such as Figure 3 As shown, the adjustment assembly 10 also includes at least one guide rod 5. One end of the guide rod 5 is connected to the movable member 2, and the other end of the guide rod 5 is movably connected to the fixed member 1. The guide rod 5 is used to guide the movement of the movable member 2, so that the movable member 2 can move in the first direction a.

[0063] Furthermore, one end of the guide rod 5 is fixedly connected to the moving part 2, and the guide rod 5 can move along the first direction a together with the moving part 2. The other end of the guide rod 5 is movably connected to the fixing part 1. The fixing part 1 is provided with a guide hole, and the other end of the guide rod 5 is fitted into the guide hole with a clearance. When the second adjusting part 4 drives the moving part 2 to move, the guide rod 5 can move in the guide hole, thereby playing a guiding role.

[0064] In an alternative embodiment, one end of the guide rod 5 is movably connected to the moving member 2, and the other end of the guide rod 5 is fixedly connected to the fixing member 1. The guide rod 5 remains stationary, and when the moving member 2 moves, the guide rod 5 can move relative to the moving member 2, thereby guiding the moving member 2.

[0065] In one embodiment, multiple guide rods 5 are provided to ensure the guiding effect of the moving part 2. In addition, when the second adjusting member 4 acts on the moving part 2, the guide rods 5 can prevent the moving part 2 from rotating around a certain axis.

[0066] On the other hand, such as Figure 1 As shown, this utility model embodiment provides a spindle device, including a spindle assembly and an adjustment component 10 as described in the above embodiment. The spindle assembly includes a spindle, a bushing 20 and a bushing seat 30. The bushing seat 30 is sleeved on the outside of the bushing 20, and the bushing 20 is sleeved on the outside of the spindle. The fixing member 1 of the adjustment component 10 is connected to the bushing seat 30, and the moving member 2 of the adjustment component 10 is connected to the bushing 20.

[0067] Since the moving part 2 of the adjusting component 10 is connected to the bushing 20, when the moving part 2 reciprocates along the first direction a under the action of the first adjusting part 3 and the second adjusting part 4, the bushing 20 will move synchronously, thereby driving the spindle to change its position in the corresponding direction, thus accurately controlling the position of the spindle and improving the machining accuracy of the spindle.

[0068] In one embodiment, the bushing seat 30 is provided with a receiving groove 303, the adjusting component 10 is located in the receiving groove 303, and the moving member 2 is located between the bushing seat 30 and the fixing member 1, which can restrict the moving member 2 within the receiving groove 303, thereby limiting the movement range of the moving member 2. Specifically, the guide portion 22 of the moving member 2 extends out of the receiving groove 303 and is connected to the bushing 20, and the moving body 21 of the moving member 2 is located in the receiving groove 303.

[0069] In one embodiment, such as Figure 1 , Figure 2 As shown, multiple adjustment components 10 are provided, and the fixing members 1 of the multiple adjustment components 10 are spaced apart around the bushing seat 30, enabling adjustment of the bushing seat in multiple directions. Multiple receiving slots 303 are provided, with each adjustment component 10 corresponding to one receiving slot 303. The bushing seat 30 has a first side and a second side connected along its circumference. Adjustment components 10 are provided on both the first and second sides. The adjustment component 10 on the first side is used to drive the bushing 20 to move along the first direction a, and the adjustment component 10 on the second side is used to drive the bushing 20 to move along the second direction b, enabling precise adjustment of the bushing 20 in two directions. The first direction a and the second direction b intersect, for example, the first direction a and the second direction b are perpendicular.

[0070] Further, let's take the two adjustment components 10 as an example for explanation.

[0071] The adjustment assembly 10 includes a first adjustment assembly 10a and a second adjustment assembly 10b, which have the same structure. The fixing member 1 of the first adjustment assembly 10a is installed on the first side of the bushing seat 30, and the fixing member 1 of the second adjustment assembly 10b is installed on the second side of the bushing seat 30. The first adjustment assembly 10a and the second adjustment assembly 10b can adjust the bushing 20 from different directions.

[0072] The first adjustment component 10a is used to adjust the position of the bushing 20 in the first direction a, and the second adjustment component 10b is used to adjust the position of the bushing 20 in the second direction b. By working together, the first adjustment component 10a and the second adjustment component 10b can achieve precise adjustment of the bushing 20 in both directions, enabling the spindle to achieve high-precision positioning in a two-dimensional plane, thereby improving machining accuracy.

[0073] Wherein, the first direction a is the X direction and the second direction b is the Y direction. The first adjustment component 10a and the second adjustment component 10b can realize the adjustment of the spindle at any position on the XY plane, which improves the adjustment accuracy and has a wide range of applications.

[0074] In one embodiment, such as Figure 2 , Figure 3 As shown, the guide includes a first guide 201 and a second guide 202, which are embedded in the flange 204 of the bushing 20. The first guide 201 has a first guide groove 2011 extending along the second direction b, and the guide portion 22 of the moving part 2 of the first adjusting assembly 10a is disposed in the first guide groove 2011. The second guide 202 has a second guide groove 2021 extending along the first direction a, and the guide portion 22 of the moving part 2 of the second adjusting assembly 10b is disposed in the second guide groove 2021.

[0075] The first guide groove 2011 is used to guide the moving part 2 of the first adjustment assembly 10a when the bushing 20 moves in the second direction b, and the second guide groove 2021 is used to guide the moving part 2 of the second adjustment assembly 10b when the bushing 20 moves in the first direction a.

[0076] The movable part 2 of the first adjusting assembly 10a is located in the first guide groove 2011, and the first guide groove 2011 extends along the second direction b, such that when the movable part 2 of the first adjusting assembly 10a moves, the bushing 20 moves along the first direction a with the movable part 2, and the first guide groove 2011 and the movable part 2 of the first adjusting assembly 10a cannot move relative to each other in the first direction a. When the second adjusting assembly 10b drives the bushing 20 to move along the second direction b, the guide portion 22 of the movable part 2 of the first adjusting assembly 10a can move along the first guide groove 2011, avoiding interference between the first adjusting assembly 10a and the movement of the bushing 20, and ensuring the motion coordination between the bushing 20 and the movable parts 2 of each adjusting assembly 10.

[0077] The movable part 2 of the second adjusting assembly 10b is located in the second guide groove 2021, and the second guide groove 2021 extends along the first direction a, such that when the movable part 2 of the second adjusting assembly 10b moves, the bushing 20 moves along the first direction a together with the movable part 2, and the second guide groove 2021 and the movable part 2 of the second adjusting assembly 10b cannot move relative to each other in the second direction b. When the first adjusting assembly 10a drives the bushing 20 to move along the first direction a, the guide portion 22 of the movable part 2 of the second adjusting assembly 10b can move along the second guide groove 2021, avoiding interference of the second adjusting assembly 10b with the movement of the bushing 20, and ensuring the motion coordination between the bushing 20 and the movable parts 2 of each adjusting assembly 10.

[0078] In one embodiment, such as Figure 2 As shown, the bushing seat 30 has an inner cavity 301. The bushing 20 includes a bushing body 203 and a flange 204. The flange 204 is disposed at one end of the bushing body 203 and extends from the outer peripheral surface of the bushing body 203 in a direction away from the central axis of the bushing body 203. A first guide member 201 and a second guide member 202 are embedded in the flange 204. The bushing body 203 passes through the inner cavity 301. The flange 204 can abut against the bushing seat 30. There is a gap between the outer wall surface of the bushing body 203 and the inner wall surface of the inner cavity. By adjusting the assembly 10, the bushing 20 can be moved in the inner cavity 301, thereby fine-tuning the position of the bushing 20, and further fine-tuning the position of the spindle.
