Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a guide rail slider gap adjustment device and machine tool equipment. Background Technology

[0002] In the field of high-precision machining, the performance of ultra-precision machine tools directly determines machining quality and efficiency. Especially with the continuous advancement of micro-nano fabrication technology, the structural rigidity of machine tools has become particularly important for ensuring stability during machining and achieving nanometer-level or even higher precision. Structural rigidity not only relates to the machine tool's resistance to deformation but also directly affects the relative positional accuracy between the tool and the workpiece, forming the foundation for ensuring machining accuracy. Poor machine tool rigidity will directly impact machining accuracy.

[0003] Meanwhile, simply increasing rigidity and preload will correspondingly increase friction, causing the temperature to rise continuously during production. Thermal deformation of the machining system has a significant impact on machining accuracy, especially in precision machining and large-part machining, where machining errors caused by thermal deformation can sometimes account for 50%-70% of the total workpiece error. Therefore, properly adjusting machine tool rigidity and preload is essential.

[0004] Therefore, adjusting the rigidity and preload of the machine tool is a crucial step, as it is necessary to effectively improve the accuracy of the machine tool while preventing excessive friction. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides a guide rail slider gap adjustment device and machine tool equipment.

[0006] This utility model provides the following technical solution: A guide rail slider gap adjustment device includes a mounting base and an adjustment block.

[0007] The mounting base is installed on the Z-axis fixed seat of the machine tool equipment. The mounting base is assembled and connected to the vertical slider of the machine tool equipment through a connector. The adjusting block is disposed between the mounting base and the vertical slider. The end face of the adjusting block near the vertical slider is an inclined adjustment surface. The plane on which the adjustment surface is located is perpendicular to the horizontal plane. By driving the adjusting block to move horizontally along the end face of the mounting base near the vertical slider, the gap between the slide groove of the vertical slider mounted on the mounting base and the guide rail on the working end can be adjusted.

[0008] As a further improvement to the above technical solution, a complementary block is provided between the adjusting block and the vertical slider. The complementary block is assembled and connected to the vertical slider. The end face of the complementary block near the adjusting block is an inclined complementary surface. The inclination direction of the complementary surface is opposite to the inclination direction of the adjusting surface. The complementary surface fits and cooperates with the adjusting surface.

[0009] As a further improvement to the above technical solution, the connector is a connecting column that can extend and retract horizontally relative to the mounting base. The adjusting block has a through slot corresponding to the connecting column on its end face near the mounting base in the horizontal direction. The connecting column passes through the slot and the through hole of the complementary block in sequence, and is finally assembled and connected with the vertical slider.

[0010] As a further improvement to the above technical solution, the adjustment block has multiple long grooves on its end face near the mounting base.

[0011] As a further improvement to the above technical solution, the angle between the adjustment surface and the end face of the mounting base near the vertical slider is α, and the value range of α is: 0.5°≤α≤2°.

[0012] As a further improvement to the above technical solution, multiple adjustment blocks are provided along the vertical direction, corresponding to the number of vertical sliders.

[0013] As a further improvement to the above technical solution, the slider gap adjustment device further includes a synchronous guide rod, which passes through each of the corresponding vertical sliders in sequence along the vertical direction.

[0014] As a further improvement to the above technical solution, the side of the mounting base is provided with an adjustment seat, and a first adjustment bolt is provided on the adjustment seat. The first adjustment bolt is threaded into the adjustment block near the end of the adjustment block.

[0015] As a further improvement to the above technical solution, a second adjusting bolt is also provided on the adjusting seat through a threaded connection, and the end of the second adjusting bolt near the adjusting block presses against the side of the adjusting block.

[0016] As a further improvement to the above technical solution, the complementary block is provided with a limiting step on the side near the adjusting seat, and the limiting step is located on the outer side wall of the vertical slider near the adjusting seat.

[0017] This utility model also provides a machine tool device, including the guide rail slider gap adjustment device as described above.

[0018] Compared with related technologies, the beneficial effects of this utility model are: The guide rail slider gap adjustment device provided by this utility model has the following specific operating procedure when it is necessary to adjust the gap between the guide rail and the vertical slider during the assembly of machine tools: First, the adjusting block located between the mounting base and the vertical slider is moved horizontally. The adjusting block is located between the mounting base and the vertical slider, and its position and movement directly affect the gap adjustment effect.

[0019] Next, after moving the adjusting block to the appropriate position, the vertical slider and the mounting base need to be assembled and connected using the connector. During the assembly process, the vertical slider and the mounting base will gradually move closer to each other, clamping the adjusting block in the process.

[0020] It is worth noting that the adjusting block has an inclined adjustment surface on the side near the vertical slider. Different positions of this inclined adjustment surface abut against the vertical slider produce different effects. Because the adjustment surface is inclined, different positions contacting the vertical slider generate forces of varying magnitudes and directions, thus limiting the distance between the mounting base and the vertical slider. In this way, the gap between the vertical slider's groove and the guide rail on the working end can be adjusted. This adjustment method is very convenient and efficient, requiring no complex operating procedures or professional skills, and can complete the initial gap adjustment in a short time.

[0021] After assembling the guide rail and vertical slider at the working end, if further precise adjustment is needed due to a gap, this can be achieved by loosening the connecting parts. Loosening the connecting parts allows the adjusting block to push the vertical slider, causing it to move slightly. This slight movement enables high-precision fine-tuning of the gap between the vertical slider's groove and the guide rail at the working end. This fine-tuning ensures a high level of assembly accuracy for the machine tool, while also guaranteeing good rigidity during subsequent use. It reduces problems such as vibration and wear caused by improper gaps, extends the machine's service life, and improves its performance and stability.

[0031] Combination Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a guide rail slider gap adjustment device, including a mounting base 200 and an adjustment block 300.

[0032] The mounting base 200 is installed on the Z-axis fixed base 110 of the machine tool. The Z-axis fixed base 110 usually adopts a U-shaped structure. Due to accuracy and structural reasons, the vertical movement of the working end 130 is driven by a dual linear motor. The mounting base 200 and the vertical slider 120 of the machine tool are assembled and connected by a connector. The adjusting block 300 is disposed between the mounting base 200 and the vertical slider 120. The end face of the adjusting block 300 near the vertical slider 120 is an inclined adjustment surface 310. The plane on which the adjustment surface 310 is located is perpendicular to the horizontal plane. By driving the adjusting block 300 to move horizontally along the end face of the mounting base 200 near the vertical slider 120, the gap between the slide groove 121 of the vertical slider 120 installed on the mounting base 200 and the guide rail 131 on the working end 130 can be adjusted.

[0033] The guide rail slider gap adjustment device provided in this embodiment operates as follows when adjusting the gap between the guide rail 131 and the vertical slider 120 during machine tool assembly: First, the adjusting block 300 located between the mounting base 200 and the vertical slider 120 is moved horizontally. The adjusting block 300 is positioned between the mounting base 200 and the vertical slider 120, and its position and movement directly affect the gap adjustment effect.

[0034] Next, after the adjusting block 300 is moved to the appropriate position, the vertical slider 120 and the mounting base 200 need to be assembled and connected using the connector. During the assembly process, the vertical slider 120 and the mounting base 200 will gradually move closer to each other, and in this process, the adjusting block 300 will be clamped.

[0035] An inclined adjustment surface 310 is provided on the side of the adjustment block 300 near the vertical slider 120. Different positions of this inclined adjustment surface 310 abut against the vertical slider 120 produce different effects. Because the adjustment surface 310 is inclined, different positions contacting the vertical slider 120 will generate forces of different magnitudes and directions, thereby limiting the distance between the mounting base 200 and the vertical slider 120. In this way, the gap between the groove 121 of the vertical slider 120 and the guide rail 131 on the working end 130 can be adjusted. This adjustment method is very convenient and efficient, requiring no complex operating procedures or professional skills, and can complete the initial adjustment of the gap in a short time.

[0036] After assembling the guide rail 131 of the working end 130 with the vertical slider 120, if further precise adjustment of the gap is required, this can be achieved by loosening the connecting parts. Loosening the connecting parts allows the adjusting block 300 to push the vertical slider 120, causing it to move slightly. This slight movement enables high-precision fine-tuning of the gap between the groove 121 of the vertical slider 120 and the guide rail 131 on the working end 130. This fine-tuning ensures a high level of assembly accuracy for the machine tool, guarantees good rigidity during subsequent use, reduces vibration and wear caused by improper gaps, extends the service life of the equipment, and improves its working performance and stability.

[0037] In some specific embodiments, a complementary block 400 is provided between the adjusting block 300 and the vertical slider 120. The complementary block 400 is assembled and connected to the vertical slider 120. The end face of the complementary block 400 near the adjusting block 300 is an inclined complementary surface 410, the inclination direction of which is opposite to that of the adjusting surface 310. The complementary surface 410 and the adjusting surface 310 fit together. In actual operation, when it is necessary to adjust the gap between the guide rail 131 and the vertical slider 120, the adjusting block 300 will be driven to move horizontally. At this time, due to the fit between the complementary surface 410 and the adjusting surface 310, the movement of the adjusting block 300 will cause the complementary block 400 to change accordingly. Specifically, this fit allows the complementary block 400 to provide horizontal support force to the vertical slider 120 during the movement of the adjusting block 300. This supporting force is not a simple unidirectional action, but is evenly and stably distributed on the contact surface between the vertical slider 120 and the complementary block 400, which can effectively resist various external forces generated during the operation of the machine tool.

[0038] This design ensures reliable assembly between the vertical slider 120 and the connecting seat. During prolonged machine tool operation or under heavy loads, the vertical slider 120 will not separate from the connecting seat or experience excessive wobbling due to clearance changes or external forces, thus guaranteeing the stability of the machine tool structure. Simultaneously, this design also ensures the assembly rigidity of the vertical slider 120. Rigidity is a crucial indicator of a mechanical component's resistance to deformation; higher assembly rigidity means that the vertical slider 120 can maintain good shape and positional accuracy under stress, thereby improving the machining accuracy and service life of the machine tool.

[0039] Combination Figure 3 , Figure 6As shown, in some specific embodiments, the connector is a connecting post 210 that can extend and retract horizontally relative to the mounting base 200. The adjusting block 300 has a through-slot 320 on its end face near the mounting base 200, corresponding to the connecting post 210. The connecting post 210 passes sequentially through the through-hole of the slot 320 and the complementary block 400, and finally connects to the vertical slider 120. Specifically, the connecting post 210 can be an electrically controlled telescopic rod or a multi-stage screw with threaded engagement. In actual adjustment, by driving the connecting post 210 to extend and retract relative to the mounting base 200, the tightness between the vertical slider 120 and the mounting base 200 can be precisely controlled. When the connecting post 210 extends, the connection between the vertical slider 120 and the mounting base 200 gradually tightens, restricting the movement of the vertical slider 120; while when the connecting post 210 retracts, the connection loosens, providing some space for the vertical slider 120 to move. This variation in tension allows the adjusting block 300 to be flexibly displaced between the vertical slider 120 and the mounting base 200. Operators can easily adjust the gap by simply controlling the extension and retraction of the connecting column 210. The entire operation is convenient and quick, greatly improving assembly and adjustment efficiency.

[0040] Furthermore, the design of the connecting post 210 passing through the elongated slot 320 on the adjusting block 300 facilitates precise positioning of the adjusting block 300. During machine tool operation, the adjusting block 300 needs to be stably positioned between the vertical slider 120 and the mounting base 200 to perform its function of adjusting the clearance. Through the cooperation of the connecting post 210 and the elongated slot 320, the adjusting block 300 can only move within the range defined by the elongated slot 320 and cannot detach from the vertical slider 120 and the mounting base 200. This positioning method is simple and effective, avoiding equipment failure and safety hazards caused by the adjusting block 300 falling off, ensuring the reliability and stability of this embodiment in actual use, and providing a strong guarantee for the efficient operation of the machine tool.

[0041] In some specific embodiments, the adjusting block 300 has multiple elongated slots 320 and multiple corresponding connecting posts 210 on its end face near the mounting base 200. The arrangement of multiple connecting posts 210 greatly enhances the connection strength between the mounting base 200 and the vertical slider 120. When the machine tool is subjected to various external forces, such as vibration, impact, or load changes, the multiple connecting posts 210 can share the force together, avoiding loosening or breakage of the connection due to excessive force on a single connection point. This effectively ensures a reliable connection between the mounting base 200 and the vertical slider 120, providing a solid guarantee for the stable operation of the machine tool.

[0042] Meanwhile, the design of multiple elongated slots 320 also plays a crucial role in reliably limiting the movement of the adjusting block 300. During machine tool operation, the adjusting block 300 needs precise displacement adjustment between the vertical slider 120 and the mounting base 200 according to actual requirements to achieve precise control of the gap between the guide rail 131 and the slider. However, to prevent excessive displacement or deviation from the predetermined position during movement, the multiple elongated slots 320 serve a critical limiting function. Each elongated slot 320 sets a clear range and boundary for the movement of the adjusting block 300, ensuring that the adjusting block 300 can only move within the space defined by the elongated slot 320. This limiting method is not only simple and effective but also ensures that the adjusting block 300 maintains the correct position and posture during movement, thereby guaranteeing the accuracy and stability of the gap adjustment.

[0043] In some specific embodiments, the angle between the adjusting surface 310 and the end face of the mounting base 200 near the vertical slider 120 is α, and the value of α ranges from 0.5° to 2°. From the perspective of adjustment accuracy, setting the α angle of the adjusting surface 310 to a smaller value has significant advantages. During the operation of the machine tool, the gap between the guide rail 131 and the vertical slider 120 needs to be precisely controlled to ensure machining accuracy and the stability of equipment operation. When the α angle is small, the adjustment block 300 can make more subtle and precise changes to the position of the vertical slider 120 during movement. Because a smaller angle means that for every unit distance the adjustment block 300 moves, the displacement change of the vertical slider 120 in the direction perpendicular to the guide rail 131 is relatively small, the operator can more accurately control the gap size and avoid the gap not meeting the requirements due to excessive adjustment range, thereby facilitating the assurance of adjustment accuracy between the vertical slider 120 and the guide rail 131.

[0044] Meanwhile, a smaller α angle setting also helps ensure the reliability of the support provided by the adjusting block 300 to the vertical slider 120. When the machine tool is subjected to various external forces, such as cutting forces and vibration impacts, the vertical slider 120 requires stable support to maintain its position and motion stability. When the α angle is smaller, the contact surface distribution between the adjusting block 300 and the vertical slider 120 is more reasonable, and the pressure transmission is more uniform. The adjusting block 300 can better disperse and transmit the force it bears to the mounting base 200, reducing the risk of damage to the adjusting block 300 or the vertical slider 120 due to local stress concentration, thereby ensuring the reliability and stability of the support provided by the adjusting block 300 to the vertical slider 120.

[0045] In some specific embodiments, multiple adjustment blocks 300 are provided along the vertical direction, corresponding to the number of vertical sliders 120, which facilitates ensuring the reliability of the transmission cooperation between the vertical sliders 120 and the guide rail 131.

[0046] In some specific embodiments, the slider gap adjustment device further includes a synchronization guide rod 500, which passes sequentially through each of the corresponding vertical sliders 120 in the vertical direction. In actual operation, the synchronization guide rod 500 plays a crucial role. During machine tool operation, the vertical sliders 120 often need to work collaboratively to complete complex machining tasks. For example, in multi-axis linkage machining, vertical sliders 120 at different positions need to move simultaneously according to a predetermined trajectory and speed. If the movements of the vertical sliders 120 are not synchronized, it will lead to increased machining errors, or even scrapped workpieces. The synchronization guide rod 500, through its rigid constraint, ensures that the movements of the vertical sliders 120 remain highly consistent in the vertical direction. When a vertical slider 120 is subjected to external force and deviates from its movement, the synchronization guide rod 500 transmits force through contact with the slider, limiting its excessive deviation and prompting it to return to a synchronized motion state with the other sliders.

[0047] From the perspective of ensuring the reliability of machine tool equipment, the role of the synchronization guide rod 500 is indispensable. During long-term operation, machine tool equipment is inevitably affected by various factors, such as temperature changes, vibration, and wear. These factors can all alter the motion characteristics of the vertical slider 120. Without the constraint of the synchronization guide rod 500, the motion differences between the individual vertical sliders 120 will gradually accumulate, ultimately severely affecting the machining accuracy and stability of the machine tool. With the synchronization guide rod 500, the effects of these adverse factors can be effectively offset, ensuring that each vertical slider 120 always works synchronously according to design requirements. This greatly improves the reliability of the machine tool, reduces the probability of equipment failure, and extends the service life of the equipment.

[0048] Combination Figure 4 , Figure 5As shown, in some specific embodiments, the mounting base 200 has an adjusting seat 220 on its side. A first adjusting bolt 221 passes through the adjusting seat 220. The end of the first adjusting bolt 221 near the adjusting block 300 is threaded into the adjusting block 300. In actual operation, when the adjusting block 300 needs to be pulled back, the operator only needs to use a suitable tool (such as a wrench) to rotate the first adjusting bolt 221. Due to the transmission effect of the thread, as the first adjusting bolt 221 rotates, its end will gradually move towards the adjusting seat 220, simultaneously pulling the adjusting block 300 back. This adjustment method is simple to operate; a simple rotation action is sufficient to achieve the displacement of the adjusting block 300, greatly improving the adjustment efficiency. A second adjusting bolt 222 also passes through the adjusting seat 220 via a threaded connection. The end of the second adjusting bolt 222 near the adjusting block 300 presses against the side of the adjusting block 300. When the adjusting block 300 needs to be pushed forward, the operator rotates the second adjusting bolt 222. Driven by the thread, the second adjusting bolt 222 extends along the axis toward the adjusting block 300, and its end applies a pushing force to the side of the adjusting block 300, causing the adjusting block 300 to move away from the adjusting seat 220. This method of pushing movement by rotating the second adjusting bolt 222 is not only convenient to operate, but also allows for precise control of the moving distance of the adjusting block 300. Operators can precisely adjust the position of the adjusting block 300 by controlling the number of rotations of the second adjusting bolt 222 according to actual needs, thereby achieving efficient and accurate gap adjustment.

[0049] By setting an adjusting seat 220 on the side of the mounting base 200, and equipping it with two adjusting components, a complete and flexible adjusting block 300 adjusting system is formed. Operators can flexibly choose to rotate the first adjusting bolt 221 or the second adjusting bolt 222 to pull back or push the adjusting block 300 according to specific processing requirements and clearance adjustments. This greatly improves the convenience and accuracy of adjustment, providing a strong guarantee for the stable operation of the machine tool and high-quality processing.

[0050] In some specific embodiments, the complementary block 400 is provided with a limiting step 420 on the side near the adjusting seat 220. The limiting step 420 is located on the outer side wall of the vertical slider 120 near the adjusting seat 220, so that when the adjusting block 300 is driven to move inward, the complementary block 400 moves accordingly, ensuring the reliability of this embodiment.

[0051] The embodiments of this utility model also provide a machine tool device, which can be divided into adjustable machine tools and fixed machine tools according to its different mechanical processing functions. It includes the guide rail slider gap adjustment device in the above embodiments. The machine tool device has all the beneficial effects of the guide rail slider gap adjustment device, which will not be described in detail here.
