Description

Technical Field

[0001] The present invention relates to the technical field of mechanical assembly, and particularly relates to an axis adjustment device and a mechanical device. Background Art

[0002] In the field of mechanical assembly, ensuring the position accuracy of the axes of parts is a key link to achieve the normal operation of equipment and extend its service life. However, in the actual assembly process, due to factors such as machining errors, installation deviations, or wear during equipment use, the positions of the axes of parts often cannot fully meet the design requirements. Deviations in the axis positions may not only cause abnormal equipment functions but also trigger a series of problems, such as excessive wear of the rotating shaft, increased machine vibration, increased noise, and accelerated damage of parts due to fatigue. These problems seriously affect the performance and reliability of the equipment. To solve the above problems, axis adjustment structures are often used in the prior art to correct the positions of the axes of parts. In the existing axis adjustment structures, only a single degree of freedom can be adjusted through one adjustment mechanism, and the adjustment requirements in multiple directions (such as vertical and horizontal) cannot be met simultaneously. To achieve multi-directional adjustment, multiple sets of adjustment mechanisms need to be designed and installed separately, which leads to the complication of the overall structure, increases the manufacturing difficulty and cost. Moreover, multiple sets of adjustment mechanisms may also result in a cumbersome adjustment process, low efficiency, and further increase the manufacturing and maintenance costs due to the high precision requirements for the cooperation of multiple sets of adjustment mechanisms. In addition, the complex mechanism may reduce the reliability of the system due to the increase in components and increase the probability of failures. Therefore, how to meet the multi-directional adjustment requirements of the axes of parts and reduce the overall complexity of the adjustment mechanism has become an urgent technical problem to be solved at present.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] Embodiment 1

[0052] Please refer to Figures 1 to 7As shown in the figure, in an embodiment of the present invention, an axis adjustment device 10 is provided. The axis adjustment device 10 includes a base 100, a bearing seat 200, an adjustment mechanism 300, and a locking structure 400. An adjustment space 30 is provided on the base 100; the bearing seat 200 is adjustably arranged in the adjustment space 30; the adjustment mechanism 300 is arranged between the base 100 and the bearing seat 200. The adjustment mechanism 300 includes an adjustment screw 310 horizontally arranged and rotatably connected to the base 100, a lower sliding seat 320 arranged below the adjustment screw 310, and a wedge block 330 threadedly connected to the adjustment screw 310 and placed between the lower sliding seat 320 and the bearing seat 200. The lower sliding seat 320 and the bearing seat 200 are limited and abutted in the axial direction of the adjustment screw 310. A bevel structure is provided between the wedge block 330 and the bearing seat 200, and a flat structure is provided between the wedge block 330 and the lower sliding seat 320; the locking structure 400 includes a horizontal working state for locking the bearing seat 200 and the wedge block 330, and a vertical working state for locking the lower sliding seat 320 and the base 100; when the locking structure 400 is in the horizontal working state, the adjustment screw 310 can push the bearing seat 200 and the lower sliding seat 320 to be adjusted in the horizontal direction through the wedge block 330; when the locking structure 400 is in the vertical working state, the adjustment screw 310 can push the bearing seat 200 to be adjusted in the vertical direction through the wedge block 330.

[0053] Overall, when the axis adjustment device 10 is in use, the base 100 can serve as an installation foundation to carry the bearing seat 200, the adjustment mechanism 300, and the locking structure 400, ensuring the installation stability of the bearing seat 200, the adjustment mechanism 300, and the locking structure 400. Moreover, the adjustment mechanism 300 can drive the wedge block 330 to perform reciprocating motion through the adjustment screw 310. Among them, the bearing seat 200 is used to install bearings, and the position of the axis of the bearing in the vertical and horizontal directions can be adjusted through the axis adjustment device 10.

[0054] When the locking structure 400 is in the horizontal working state, the locking structure 400 can lock the bearing seat 200 and the wedge block 330. At this time, the adjustment screw 310 can push the bearing seat 200 and the lower sliding seat 320 to be adjusted in the horizontal direction through the wedge block 330.

[0055] When the locking structure 400 is in the vertical working state, the locking structure 400 can lock the lower sliding seat 320 and the base 100. At this time, the adjustment screw 310 can push the bearing seat 200 to be adjusted in the vertical direction through the wedge block 330.

[0056] By combining the adjusting screw 310, the wedge block 330, the lower sliding seat 320, and the locking structure 400, the axis adjustment device 10 can achieve adjustments in two degrees of freedom (vertical and horizontal) under the drive of a single adjusting screw 310. There is no need to set up multiple sets of adjustment mechanisms 300, making the overall structure more compact and reducing the complexity of manufacturing and assembly. Since a single adjusting screw 310 is used for driving, the number of components is significantly reduced, thereby reducing the failure risk caused by the increase in components.

[0057] Moreover, by providing an inclined plane structure between the wedge block 330 and the bearing seat 200, and a flat plane structure between the wedge block 330 and the lower sliding seat 320, the cooperation of the inclined plane structure and the flat plane structure can convert the slight rotation of the adjusting screw 310 into precise displacement adjustment, enabling the axis adjustment device 10 to achieve stepless adjustment, thus better meeting the requirements of high-precision assembly.

[0058] In addition, the locking structure 400 can be flexibly switched between the horizontal working state and the vertical working state. In the horizontal working state, the adjusting screw 310 pushes the bearing seat 200 and the lower sliding seat 320 to move in the horizontal direction; in the vertical working state, the adjusting screw 310 pushes the bearing seat 200 to move in the vertical direction through the wedge block 330. This adjustment method in two degrees of freedom (vertical and horizontal) enhances the applicability of the axis adjustment device 10 and can better meet the axis adjustment requirements in different scenarios. In addition, the locking structure 400 ensures the stability after adjustment, avoids the axis position deviation caused by external vibration or other interference factors, and improves the reliability.

[0059] In an embodiment of the present invention, as Figure 2 and Figure 6 shown in the embodiment, the inclined plane structure includes a first inclined plane provided at the top of the wedge block 330 and a second inclined plane provided on the bearing seat 200, and the first inclined plane and the second inclined plane are slidably connected. Designers can adjust the inclination angles of the first inclined plane and the second inclined plane according to the usage needs, and no specific limitation is made here.

[0060] In an embodiment of the present invention, as Figure 1 and Figure 2 shown in the embodiment, the base 100 includes a first support portion 110 and a second support portion 120 arranged at intervals, an adjustment space 30 is formed between the first support portion 110 and the second support portion 120, and an avoidance channel 40 for the horizontal movement of the wedge block 330 is provided on the first support portion 110 and / or the second support portion 120.

[0061] By disposing the first support portion 110 and the second support portion 120 on the base 100 at an interval, an adjustment space 30 can be formed between the first support portion 110 and the second support portion 120 , so that the bearing seat 200 can be adjusted in the adjustment space 30 .

[0062] Preferably, the first support portion 110 and the second support portion 120 are both provided with an avoidance channel 40 for the horizontal movement of the inclined wedge block 330, so as to avoid affecting the horizontal movement of the inclined wedge block 330, and then the adjusting screw 310 can be used to drive the inclined wedge block 330 to reciprocate between the first support portion 110 and the second support portion 120.

[0063] The present invention optimizes space utilization by coordinating the adjustment space 30 with the avoidance channel 40, maintains the compactness of the structure of the base 100 while achieving multi-degree-of-freedom adjustment, reduces unnecessary parts, and reduces manufacturing costs and assembly difficulty.

[0064] In an embodiment of the present invention, Figure 3 In the illustrated embodiment, the base 100 further includes a guide portion 130 disposed at the bottom of the adjustment space 30 . The extension direction of the guide portion 130 is parallel to the adjustment screw 310 . The lower sliding seat 320 is slidably disposed on the guide portion 130 .

[0065] By providing a guide block at the bottom of the adjustment space 30 and slidably arranging the lower lower seat 320 on the guide block, the movement stability and accuracy of the lower lower seat 320 are significantly improved, and adjustment errors caused by offset or shaking are avoided. In addition, by making the lower lower seat 320 slide and cooperate with the guide part 130, friction and wear are reduced, thereby extending the service life.

[0066] In an embodiment of the present invention, Figure 5 In the illustrated embodiment, a horizontal slide groove 321 is provided at the bottom of the lower slide seat 320 , and the lower slide seat 320 is slidably connected to the guide portion 130 via the horizontal slide groove 321 .

[0067] The horizontal slide groove 321 cooperates with the guide part 130, so that the lower slide seat 320 can be limitedly connected with the guide part 130, ensuring the stability of the movement of the lower slide seat 320 in the horizontal direction, while reducing the friction and shaking during the movement, and improving the accuracy and stability of the adjustment. In addition, the installation method of the horizontal slide groove 321 cooperating with the guide part 130 is also conducive to simplifying the assembly difficulty and enhancing the assembly reliability between the lower slide seat 320 and the base 100.

[0068] In an embodiment of the present invention, Figure 4In the illustrated embodiment, a vertical slider 210 is provided at the bottom of the bearing housing 200, and a vertical chute 322 is provided at the side of the lower sliding seat 320. The bearing housing 200 is slidably connected to the vertical chute 322 through the vertical slider 210.

[0069] Through the cooperation of the vertical chute 322 and the vertical slider 210, the movement stability of the bearing housing 200 in the vertical direction is improved, so that the bearing housing 200 can move relative to the lower sliding seat 320 only in the vertical direction, effectively reducing the offset and shaking of the bearing housing 200 during the movement, thereby improving the adjustment accuracy and reliability. Moreover, by adopting the installation method of the cooperation of the vertical chute 322 and the vertical slider 210, it is also beneficial to simplify the assembly difficulty and enhance the assembly reliability between the bearing housing 200 and the lower sliding seat 320.

[0070] Further, there are two vertical sliders 210, and the two vertical sliders 210 are arranged at intervals on the bearing housing 200. One vertical chute 322 is correspondingly provided on each side of the lower sliding seat 320, and the vertical slider 210 is slidably connected to the corresponding vertical chute 322.

[0071] By providing two vertically spaced-apart vertical sliders 210, the bearing housing 200 can form a multi-point fit with the lower sliding seat 320, further improving the movement stability between the bearing housing 200 and the lower sliding seat 320. Moreover, the two vertical sliders 210 can effectively disperse the force, reduce the wear and deformation caused by single-point load, thereby extending the service life of the bearing housing 200 and the lower sliding seat 320.

[0072] Preferably, the two vertical sliders 210 are symmetrically distributed. By adopting the symmetric arrangement, the anti-eccentric load capacity of the bearing housing 200 during the movement is enhanced, ensuring that the bearing housing 200 moves smoothly in the vertical direction, thereby improving the adjustment accuracy and reliability.

[0073] In the embodiment of the present invention, as Figure 5 shown in the embodiment, the lower sliding seat 320 includes a sliding seat body 3201, two first limiting blocks 3202 arranged at intervals on one side of the sliding seat body 3201, and two second limiting blocks 3203 arranged at intervals on the other side of the sliding seat body 3201. A horizontal chute 321 is formed between the adjacent first limiting blocks 3202 and the second limiting blocks 3203, and a vertical chute 322 is formed between the adjacent first limiting blocks 3202 and / or a vertical chute 322 is formed between the adjacent second limiting blocks 3203.

[0074] Designers can adjust the number and specific structure of the first limiting blocks 3202 and the second limiting blocks 3203 according to the use requirements, and no specific limitation is made here.

[0075] Preferably, the first limiting portion and the second limiting block 3203 have the same structure. More preferably, both the first limiting block 3202 and the second limiting block 3203 are arranged in a cuboid shape, and the middle parts of the first limiting block 3202 and the second limiting block 3203 are connected to the sliding seat body 3201.

[0076] In an embodiment of the present invention, as Figure 4 shown in the embodiment, the bearing seat 200 includes a first connecting portion 220 and a second connecting portion 230 arranged at intervals. The first connecting portion 220 is provided with a first long hole 221 parallel to the adjusting screw 310, and the second connecting portion 230 is provided with a second long hole 231 parallel to the adjusting screw 310; the first supporting portion 110 is provided with a first connecting hole, and the second supporting portion 120 is provided with a second connecting hole; the axis adjusting device 10 further includes a first bolt assembly 500 for connecting the first long hole 221 and the first connecting hole, and a second bolt assembly 600 for connecting the second long hole 231 and the second connecting hole.

[0077] By using the first bolt assembly 500 to connect the first long hole 221 and the first connecting hole, and the second bolt assembly 600 to connect the second long hole 231 and the second connecting hole, the first bolt assembly 500 and the second bolt assembly 600 can provide a vertical adjustment margin for the bearing seat 200 in the vertical direction, and the first long hole 221 and the second long hole 231 can provide a horizontal adjustment margin for the bearing seat 200.

[0078] Designers can adjust the specific structure of the first bolt assembly 500 and the first bolt assembly 500 according to the usage requirements, and no specific limitation is made here. Preferably, the first bolt assembly 500 and the second bolt assembly 600 have the same structure, and the first bolt assembly 500 and the second bolt assembly 600 are arranged at the same height.

[0079] More preferably, as Figure 2 shown in the embodiment, the first bolt assembly 500 includes a first connecting bolt, a first connecting nut arranged on the first connecting bolt, and a first gasket. The first connecting bolt passes through the first long hole 221 and is threadedly connected to the first connecting hole. The first connecting nut is arranged on the first connecting bolt and is axially limited and matched with the first long hole 221, and the first gasket is arranged between the first connecting nut and the first connecting portion 220.

[0080] Moreover, at least part of the first connecting bolt is arranged between the first connecting portion 220 and the first connecting nut to form a first vertical adjustment section, so that the first connecting portion 220 can be vertically adjusted along the first vertical adjustment section. Designers can adjust the setting height of the first vertical adjustment section according to the usage requirements, and no specific numerical limitation is made here.

[0081] The second bolt assembly 600 includes a second connecting bolt, a second connecting nut arranged on the second connecting bolt, and a second gasket. The second connecting bolt passes through the second long slot 231 and is threadedly connected to the second connecting hole. The second connecting nut is arranged on the second connecting bolt and is axially limited and matched with the second long slot 231. The second gasket is arranged between the second connecting nut and the second connecting portion 230.

[0082] Moreover, at least part of the second connecting bolt is arranged between the second connecting portion 230 and the second connecting nut to form a second vertical adjustment section. While the first connecting portion 220 is vertically adjusted, the second connecting portion 230 can be vertically adjusted along the second vertical adjustment section. Designers can adjust the setting height of the second vertical adjustment section according to the usage requirements, and no specific numerical limit is provided here.

[0083] In an embodiment of the present invention, as Figure 3 shown in the embodiment, the second support portion 120 is provided with a mounting hole, and the adjusting screw 310 is rotatably passed through the mounting hole. One end of the adjusting screw 310 extends and is arranged in the first support portion 110, and the other end of the adjusting screw 310 is arranged outside the second support portion 120.

[0084] By providing a mounting hole on the second support portion 120 and rotatably passing the adjusting screw 310 therethrough, the adjusting screw 310 can be horizontally arranged between the first support portion 110 and the second support portion 120. Furthermore, the adjusting screw 310 can drive the wedge block 330 to move horizontally through its own rotation, and then drive the bearing seat 200 to adjust the position by using the wedge block 330.

[0085] In an embodiment of the present invention, as Figure 2 and Figure 7 shown in the embodiment, the axis adjustment device 10 further includes a fixing plate 700 arranged on the second support portion 120. The fixing plate 700 is provided with a fixing hole for the adjusting screw 310 to pass through, and the fixing plate 700 can axially limit the adjusting screw 310 along the axial direction of the adjusting screw 310.

[0086] Specifically, a convex platform portion is arranged on the adjusting screw 310, and the convex platform portion can abut against the fixing plate 700. By arranging the fixing plate 700 on the second support portion 120 and using the fixing hole on the fixing plate 700 to axially limit the adjusting screw 310, the adjusting screw 310 is prevented from moving axially or disengaging from the second support portion 120, ensuring the installation stability of the adjusting screw 310.

[0087] The designer can adjust the rotational mounting method between the adjusting screw 310 and the second support portion 120 according to the usage requirements. For example, the adjusting screw 310 is rotationally connected to the second support portion 120 through a rotating bearing, or the adjusting screw 310 is rotationally connected to the second support portion 120 through a rotating bushing.
